This harbor is located on the northern end of Beal Island. This island is opposite Jonesport on the south side of Moosabec Reach, an east-and-west thoroughfare about 6 miles long, running between the mainland on the north, and the group of islands between Chandler Bay and Pleasant Bay, on the south. It is 168 miles northeasterly of Portland, 88 miles northeasterly of Rockland, and about 38 miles southwesterly of Eastport. (See U. S. Coast and Geodetic Survey Charts Nos. 304 and 1201.) Existing project. This provides for an anchorage 10 feet deep at mean low water over an area about 600 feet long and varying in width from 1,000 feet at the 10-foot depth curve in Moosabec Reach to about 600 feet at the inner end. The mean range of tide is 11.5 feet and the spring range is 13.1 feet. The latest approved estimate of Federal cost for new work is $200,000 (July 1957). The existing project was authorized by the River and Harbor Act of June 30, 1948. The latest. published map is contained in the project document (H. Doc. 553, 80th Cong., 2d sess.). Local cooperation. Fully complied with. Terminal facilities. There are 5 privately owned wharves in Beals Harbor which are used by those engaged in lobstering and fishing. Four of the wharves are located at the inner end of the RIVERS AND HARBORS-NEW ENGLAND DIVISION 5 harbor and are bare at the lower 'stages of tide The fifth, located near the entrance to the harbor on the east side, has less than 2 feet at mean low water. All of these wharves are either of pile or braced-timber construction A short distance to the east of the harbor, in Moosabec Reach, are located a public and a private wharf. The public wharf in .Moosabec Reach is of solid-fill con- struction and open to all, while the private wharf is of pile con- struction and is used as the Beals terminal of the Jonesport-Beals ferry. Operations and results during fiscal year. Improvement dredg- ing by contract, of an anchorage 10 feet deep and 600 feet long, was in progress at the beginning of the fiscal year, and was com- pleted on August 11, 1956, with the exception of rock encountered during the dredging operations. During the period 135,969 cubic yards of ordinary material were removed. Plans and specifications were prepared for removal by contract of approximately 2,000 cubic yards of ledge which was uncovered during the dredging operations. Federal costs during the fiscal year from regular funds amounted to $117,860, all for new work. Condition at end of fiscal year. Construction of the existing project was initiated in April 1956, and was completed in August 1956, with the exception of rock removal in the anchorage area. The controlling depths at mean low water were as follows: 10.9 feet in the easterly half of the anchorage except near the limit in the southeast corner where the depth is 7.8 feet; 6.7 feet in the westerly half over a small ledge area. The total Federal costs for the existing project from regular funds have been $123,929, all for new work.

PENOBSCOT RIVER, MAINE Location. This river drains a large number of lakes and small streams in north, central and eastern Maine and, after assuming definite character as a stream, flows about 100 miles in a southerly direction'through the middle of the State, discharging into Penob- scot Bay, about 90 miles northeast of Portland, Maine. (See U. S. Coast and Geodetic Survey Chart No. 311.) Previous projects. Adopted by the River and Harbor Act of July 11, 1870, and modified by the River and Harbor Acts of March 3, 1899, and July 11, 1947. For further details of previous projects, see page 1732 of Annual Report for 1915, page 48 of Annual Report for 1938, and page 31 of Annual Report for 1949. Existing project. This provides for dredging to a depth of 22 feet between Winterport and Bucksport, about 16 miles below RIVERS AND HARBORS--NEW ENGLAND DIVISION Bangor; for straightening, widening, and deepening to 15 feet the channel near Stearns Mill and near Crosbys Narrows from 3 to 4.5 miles below Bangor; and for deepening the harbor at Bangor to 14 feet and widening it along the Bangor front, giving an additional width of from 100 to 300 feet for a length of about 2,000 feet. The project depths refer to mean low water which is 3 feet above extreme low tide. The mean range of tide at Bangor is 13.1 feet, and the extreme about 15 feet. The Federal cost of new work for the completed project was $292,020, exclusive of amounts expended under previous projects. The average annual maintenance cost during the past 5 years was $7,149.

Local cooperation. None required. Terminal facilities. The river front of Bangor has 12 wharves, most of which are of the timber-crib stone-ballasted type. Exten- sive improvements and alterations have been completed at all the oil terminals to handle increased receipts of petroleum products. Eleven of the wharves have physical connection with a railroad. On the east side of the river at Brewer, opposite Bangor, there is one water terminal, a coal handling plant having mechanical ap- pliances and three petroleum products storage plants. The re- mainder of the terminals on the east side of the river are in poor condition. At South Brewer there is a large pulp and paper plant which has water connections, oil pumping and storage facilities. There are a number of private wharves open to the public at moderate charges. At Bucksport on the north side of the river there are 3 important terminals, 1 a coal handling plant and 2 used by a large paper manufacturing plant which has terminal facilities for the receipt and storage of oil products and pulpwood. The terminal facilities are considered adequate for existing needs. Operations and results during fiscal year. Maintenance dredg- ing by the Government-owned hopper dredge Hyde to remove shoals in the 22-foot channel in Lawrence Cove area above Bucks- port was initiated in August and completed in September 1956. During the period 128,686 cubic yards pay place (credited) of ordinary material were removed. Federal costs during the fiscal year from regular funds amounted to $33,068, all for maintenance. Condition at end of fiscal year. The existing project was com- pleted in 1913. The controlling depths at mean low water were 8 REPORT OF THE CHIEF OF ENGINEERS, U. S.

ROCKLAND HARBOR, MAINE Location. This harbor is on the westerly side of Penobscot Bay, near its mouth, and about 80 miles northeast of Portland by water. It is a natural indentation of the coast line, about 10,000 feet in one direction and about 7,000 feet in the other. Protection from the east is afforded by a breakwater extending from the northerly shore about half-way across the entrance. (See U. S. Coast and Geodetic Survey Chart No. 320.) Previous project. Adopted by the River and Harbor Acts of June 3, 1896. For further details of previous project see page 27 of Annual Report for 1906. Existing project. This provides for construction and mainte- nance of a breakwater 4,346 feet long extending southerly from Jameson Point, which was completed under the previous project, dredging a short approach channel, and 3 branch channels, each with a turning basin, extending from deep water along about 1.5 miles of the central and northern waterfront to depths of 18 feet below mean low water in the outer portion and 14 feet below mean low water in the inner portion and to widths of 150 feet and 100 feet, and a channel 18 feet deep at mean low water and 100 feet wide from deep water to the vicinity of the General Foods Cor- poration marine base in the southern, part of the harbor. The mean tidal range is 9.7 feet; the extreme is 11' feet. The latest approved estimate of Federal ecost for new work is:$1,722,900. The existing project was authorized by the following Rivei and Harbor Acts: The act of June 14, 1880, provided for the break- water; act of June 29, 1956 provided for dredging of the 14-foot and 18-foot channels and ledge removal (S. Doc. 84th Cong., 1st sess.). The latest published map is in the latter document. Local cooperation. Fully complied rith. The terms of local co- operation pertinent to the existing project provide that responsible RIVERS AND HARBORS-NEW ENGLAND DIVISION 9 local interests give assurances satisfactory to the Secretary of the Army that they will provide without cost to the United States all lands, easements, and rights-of-way necessary for the construc- tion of the project and for subsequent maintenance, when and as required; hold and save the United States free from damages due to the construction and maintenance of the project; provide and maintain at local expense adequate public terminal and transfer facilities, estimated at a cost of $225,000, and open to all on equal terms. Terminal facilities. About 15,000 feet of the total water front- age of the harbor has been developed, and over 20 wharves are in active use at the present time. Wharf construction varies from timber cribs filled with stones or earth, to granite faced fills'with wooden-pile additions. Seven of the wharves have depths ranging from 10 to 15 feet; 8 have depths ranging from 5 to 9 feet; 4 have depths ranging from 1 to 4 feet; and the remainder are dry at low water. City of Rockland has provided a public landing with floats attached, having depths at mean low water of about 6 feet along- side. Facilities are considered adequate for existing commerce. (For a further description of terminal facilities, see S. Doc. 82, 84th Cong., 1st sess.) Operationsand results during fiscal year. Improvement dredg- ing, under contract, was initiated on April 12, 1957 in the 14- and 18-foot channels. Work was in progress at the end of the fiscal year and had been approximately 10 percent completed. During the period of operations 122,600 cubic yards of ordinary material were removed, principally from the 18-foot channel. Plans and specifications were prepared for the removal of ledge rock in the 14-foot channels. Federal costs during the fiscal year from regular funds amounted to $160,291, all for new work. Condition at end of fiscal year. The project is about 30 percent complete. The breakwater was completed in 1904. To complete the project there remains completion of improvement dredging and rock removal in the 14-foot channels. The controlling depth at mean low water was about 18 feet over 90 percent of the 18-foot channel area in the central harbor section at the end of June 1957.

For a rubblestone breakwater 2,250 feet long, surmounted by a superstructure of dry walls of heavy split stone enclosing a core of rubblestone from Eastern Point over Dog Bar to. Cat Ledge. b. For the removal of three ledges in the inner harbor, 1 to 12 feet and 2 to 15 feet depth at mean low water, and five ledges in the outer harbor, 4 to 18 feet and 1 to 25 feet depth at mean low water, aggregating a total of 2,206 cubic yards, place measurement. c. For removal to depth of 15 feet below mean low water of ledges and boulders obstructing the approach to the wharves be- tween Harbor Cove and Pews wharf, near the head of the inner harbor; dredging to the same depth the channel leading past the wharves and dredging Harbor Cove to the depth of 10 feet at mean low water. Annisquam River: For a channel 8 feet deep at mean low water 60 feet wide from Gloucester Harbor to the Boston & Maine Rail- road bridge, 100 feet wide from the railroad bridge to the mouth of the river, and 200 feet wide across the bar in Ipswich Bay, in- cluding the removal of a ledge near the Gloucester Harbor en- trance; and for a dredged anchorage area about 17 acres in extent and 8 feet deep at the entrance of Lobster Cove. The project depths refer to mean low water. The mean range of tide in Gloucester Harbor is 8.7 feet; the ex- treme range is 12.6 feet. The mean range of tide in Annisquam River is 8.5 feet; the extreme range is about 10 feet. The latest approved estimate of Federal cost for new work is $810,000 (July 1957), exclusive of amounts expended on previous projects.

The River and Harbor Act of March 2, 1945, provides that local interests contribute one-third of the initial cost of the improvement, but not to exceed $25,000, furnish free of cost to the United States all lands, easements, rights-of- way, and spoil-disposal areas necessary for the improvement and for subsequent maintenance, when and as required, and hold and save the United States free from claims for damages resulting 22 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 from the improvement. Assurances of local cooperation were furnished during fiscal year 1949. Terminal facilities. There are in Gloucester Harbor 61 wharves worthy of mention. The depth beside the wharves varies from 0 to 20 feet at mean low water. Except for 3 wharves, 2 owned by the city and the fish pier which is leased by the city from the Com- monwealth of Massachusetts, all are private and are not available to the public. There are two commercial wharves on Annisquam River on the east bank. These facilities are considered adequate for the existing commerce of the port. For full description see Port and Terminal Facilities at the Ports of Northern New England, 1941. Condition at end of fiscal year. The existing project was about 77 percent complete. The existing project was completed in 1936 except for dredging the anchorage area in Lobster Cove in the Annisquam River. The removal of all ledges and boulders in Gloucester Harbor between Harbor Cove and Pews Wharf, and other obstructing rocks was completed in 1894; and the removal of a pinnacle rock in the outer harbor in 1896. The breakwater, which was completed in 1905, was repaired in 1940 and is in good condition. The removal of all ledges to project depth was com- pleted in 1916. The improvement of Annisquam River was com- pleted in 1936 at a cost of $33,976. Channel depths in Annisquam River need to be restored to project dimensions. The controlling depths over the ledges in the outer harbor in 1916 were from 18 to 25 feet; over ledge C in the inner harbor in 1931, 14 feet; and over ledges A and B in the inner harbor in 1940, 13 and 15 feet respec- tively; 7 feet in the channel from Ipswich Bay to Gloucester Har- bor with the exception of encroachments on the west side of the channel abreast Pearce Island having a depth of 0 feet, and on the east side of the channel just north of Rust Island having a depth of 2 feet (1953), 5 feet in the northwesterly third and +5 feet in the remaining part of the Lobster Cove anchorage. The total costs under the existing project from regular funds have been $721,862, of which $535,154 was for new work and $186,708 was for maintenance. Operationsand results during fiscal year.

The Mystic River rises in Mystic Lakes, Mass., flows in a southeasterly direction, and empties into Boston Harbor near the Boston Naval Shipyard. It is 7 miles in length. (See U. S. Coast and Geodetic Survey Chart No. 248 and U. S. Geological Survey Chart, "Boston.") Previous projects. Original project for the lower Mystic was adopted by the River and Harbor Act of March 3, 1899, and cur- tailed by the River and Harbor Act of June 25, 1910. For further details see page 1743 of Annual Report for 1915, and page 59 of Annual Report for 1938. There has been no previous project for the upper Mystic. Existing project. This provides for a channel 35 feet deep, ex- tending from the upper limit of the 35-foot channel of Boston Harbor at the Mystic River Bridge to approximately 300 feet downstream of the Malden Bridge, having widths varying from about 940 feet at its lower end, to about 1,060 feet at a point about 1,200 feet below the Malden Bridge, thence decreasing to 150 feet at its upper limit; a channel 20 feet deep from the head of the existing 35-foot channel to a point 800 feet above the Malden Bridge, with widths decreasing from 150 feet at the lower end to 75 feet through the drawspan, thence increasing to approximately 340 feet to form a turning basin above the bridge; a channel 6 feet deep and 100 feet wide from the Boston & Maine Railroad (western division) Bridge to about 2,500 feet above Wellington Bridge, about 1 mile, and thence 4 feet deep, gradually narrowing from 100 feet to 50 feet at the upper end for about 2 miles to the head of commercial navigation at Craddock Bridge in Medford. The project depths refer to mean low water. The mean range of tide is 9.6 feet at Mystic River Bridge, 9.6 feet at Wellington Bridge, and 9.3 feet at Craddock Bridge. The extreme range is 13.7 feet. The latest approved estimate of Federal cost for new work is $3,320,000 (July 1957), exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $5,957.

In the section of the river benefited by the 35-foot channel project there are on the south bank of the river four wharves aggregating over 4,000 feet of berthing space used for the receipt, storage, and shipment of coal, lumber, and gypsum. These wharves consist of substantial stone or wooden bulkheads filled solid, and in some cases fronted by pile platforms. There is also on the south bank a lumber terminal, the largest of its kind on the Atlantic coast. It is equipped with the most modern mechan- ical appliances, has railroad connection, and occupies 4,400 feet of water front. On the north bank of the river within the scope of this improvement there is a large wharf for receipt and shipment of oil on an extensive scale; immediately adjacent to this wharf is an extensive terminal constructed in connection with an iron works; downstream of the Malden Bridge there is a wharf for receipt of oil in connection with electric generating plant; on the west bank of Island End River, which flows into Mystic River on the north about midway of the 35-foot channel,. are situated two large terminal wharves, of 800 feet dockage, for receipt and ship- ment of coal, coke, tar, and oil. These wharves are connected with the 35-foot channel by a channel 30 feet deep at mean low water, dredged by private interests. None of the above wharves is publicly owned, and none is open to general public use. Beyond the scope of the authorized 35-foot channel improve- ment, and within the scope of the 20-foot channel and the improve- ment of the upper Mystic, there are on the south bank in Charles- town and Somerville about 1,850 feet, and on the north bank in Medford about 1,235 feet of available dockage, of which 450 feet on the south bank and 435 feet on the north bank are customarily in use. A large automobile assembly plant is located on the south bank in Somerville. The existing wharves consist of stone and wooden bulkheads, solid filled. None is publicly owned, but two are open to the public on payment of wharfage charges. The capacities of the lower Mystic are being utilized to a gratifying extent. These facilities are considered adequate for existing commerce. (For further de- tails see "The Port of Boston, Mass.-Port Series No. 3-Revised 1946.") Operations and results during fiscal year. Improvement dredg- ing, by contract, was in progress at the beginning of the fiscal year in the 35-foot channel. Work was completed in March 1957. Dur- ing the period 1,120,813 cubic yards of ordinary material were re- moved, making a total of 1,742,546 cubic yards of ordinary material removed under the contract. Preliminary work in con- nection with ledge removal in the 35-foot channel was completed during the year. Costs during the fiscal year from regular funds amounted to $1,128,968, all for new work. Condition at end of fiscal year. The existing project is about 85 percent complete. To complete the project there remains the removal of ledge in the 35-foot channel. The controlling depths at RIVERS AND HARBORS-NEW ENGLAND DIVISION 25 mean low water in Mystic River at the time the various sections were last surveyed were: 30 feet over ledge in the 35-foot channel (1956) ; 20 feet in the 20-foot channel (1948) ; 3 feet in the 6-foot channel; 3 feet in the 4-foot channel, but narrowed in width (1946). The total costs under the existing project from regular funds have been $2,751,655, of which $2,543,062 was for new work and $208,593 was for maintenance.

It was recommended in House Document No. 349, 84th Congress, 2d session that the existing project be modified to include the deepening and widen- ing of Reserved Channel to a depth of 35 feet and width of 430 feet extending about 1 mile from the 40-foot main ship channel to the L-Street Bridge, at an estimated Federal cost of $790,000 (July 1957). Local cooperation. Fully complied with. Terminal facilities. There are 183 wharves and piers in the Harbor, not including the Mystic River, Weymouth Fore River, and Town River, which are reported elsewhere. In addition, there are 4 ferry slips and 2 car floats. Of the terminals, 28 are publicly owned, 3 are open to public use, 77 have mechanical-handling facilities, and 57 have railroad connections. The facilities are con- sidered adequate for the present requirements of commerce. (For the latest full description of Terminal Facilities, see Port Series No. 3--the Port of Boston, Mass., revised 1946.) Operationsand results durinq fiscal year. Improvement dredg- ing, by contract, of the extension of President Roads Anchorage and dredging in the 35-foot area lying west of the anchorage was initiated in November 1956 and was still in progress at end of fiscal year. During the period 1,082,500 cubic yards of material were removed. Costs during the fiscal year for new work from regular funds amounted to $732,224. Snagging operations, by hired labor, were carried on throughout the year. Maintenance dredging, by Government-owned Hopper Dredge Comber, to remove shoals in the 35-foot channel at up- stream end of project connecting with the new Mystic-River 35- foot channel, was initiated and completed in July 1956. During the period 65,871 cubic yards of pay place plus natural shoaling of ordinary material were removed. Costs during the fiscal year for maintenance from regular funds amounted to $70,152. Total 28 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 costs during the fiscal year from regular funds amounted to $802,376, of which $732,224 was for new work and $70,152 was for maintenance.

Coast and Geodetic Survey Chart No. 246.) : Existing qIroject.: This provides for a channel 18 feet deep and 175 feet wide to Commercial Point, thence 15 feet deep and 100 feet wide from Commercial Point to the Neponset Highway Bridge. The project depths refer to mean low water. The mean range of tide is 9.6 feet and the extreme range is 13.7 feet. The Federal cost of new work for the completed project was $94,584. The dredging of a channel 25 feet deep and 300 feet wide from the Boston Harbor main ship channel to Commercial Point portion of the project is considered to be inactive and is excluded from the foregoing costs. The cost of this portion was last revised in 1955 and was estimated to be $709,000. The average annual maintenance cost during the past 5 years was $29,200. The existing project was authorized by the River and Har- bor Act of March 2, 1907 (H. Doc. 83, 59th Cong., 2d sess.). 30 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The latest published map is contained in the project document. Local cooperation. Fully complied with. Conditions were im- posed by the act of March 2, 1907, that the portion of the river from Neponset Highway Bridge to Milton Mills should be dredged and maintained by the Commonwealth of Massachusetts or other agency to the depth of 6 feet at mean low water, 100 feet wide up to the Granite Street Bridge, 1.15 miles; 75 feet wide thence to Godfreys wharf, 1.25 miles; and thence 50 feet wide to the rail- road bridge at Milton, a distance of 250 feet. These conditions were accepted by resolves of the Legislature of Massachusetts, ap- proved June 24, 1907, and March 5, 1908. The river was dredged by the Commonwealth of Massachusetts in 1910 and has been maintained periodically by the Commonwealth since that date. Terminal facilities. There are 15 wharves located on these waterways which are used for commercial purposes: 4 handle lumber, 4 are not being used, 1 is used for receiving and storing coal, 1 for receiving and storing coal and oil, and 1 for receiving oil and stone, 1 is a mooring wharf, 1 an outfitting wharf for recrea- tional craft and 1 is used in connection with shipbuilding and repair, and 1 for loading garbage scows. Six have mechanical- handling facilities and 2 have railroad connections. For full description see the Port of Boston, Mass.-Port Series 3-Revised 1946. Operations and results during fiscal year. Maintenance dredg- ing, by contract, to restore 15-foot depths in the channel between Dorchester Bay and Commercial Point and the Neponset River Channel from Commercial Point upstream to the highway bridge, in progress at the beginning of the fiscal year, was completed in August 1956: During the period 70,579 cubic yards of ordinary material were removed, making a total of 90,579 cubic yards of material removed under the contract. Federal costs during the fiscal year from regular funds amounted to $120,837, all for maintenance. Condition at end of fiscal year. The existing project was com- pleted. The controlling depths at mean low water were as follows: 17 feet in Dorchester Bay to about 3,000 feet downstream of Com- mercial Point (1953) ; thence 13 feet to Commercial Point (1953); thence 15.5 feet to the New York, New Haven and Hartford Railroad Bridge (1956); thence 13 feet to Neponset Highway Bridge (1956).

One, owned by the city of Fall River, is used for excursion boats and mooring small training vessels, and the other, a former steamship terminus, was reconstructed by the Common- wealth of Massachusetts. It is a large, modern, deepwater ter- minal for the receipt and shipment of general cargo. The wharves are generally open pile and timber piers extending from solid- filled stone bulkheads. Nine have mechanical handling facilities and seven have railway connections. The facilities are considered adequate for the existing needs of general commerce. (For a further description of terminal facilities, see Port and Terminal Facilities of Southern New England, No. 4, revised 1952.) Operations and results during fiscal year. Improvement dredg- ing, under a continuing contract, in the 35-foot channel was initi- ated in March 1957 and was still in progress at the end of the fiscal year. During the period approximately 412,000 cubic yards of ordinary material were removed. Costs during the fiscal year from regular funds amounted to $347,640 for new work. Condition at end of fiscal year. The existing project is about 65 percent complete. To complete the project there remains the completion of the dredging in the 35-foot channel. The con- trolling depths at mean low water were as follows: 29 feet in the 35-foot channel, 40 feet wide through Mount Hope to Globe wharf, thence 35 feet in the 35-foot channel to the wharves above the bridges (1950) ; 35 feet in the 35-foot turning basin (1950) ; 35 feet in the 35-foot channel to the Gulf Oil Co. wharf, with the exception of boulder areas in the vicinity of Common Fence Point and the Bay Oil Co. wharf where the controlling depths are 32.6 feet and 30.5 feet respectively (1955) ; 19 feet in 25-foot anchor- age (1942) ; 20 feet on Hog Island Shoal at west edge of channel (1940).

BULLOCKS POINT COVE, RHODE ISLAND Location. Bullocks Point Cove is on the east shore of Provi- dence River about three-quarters of a mile above the head of Narragansett Bay and 4.5 miles south of Providence Harbor, R. I. The lower one-half mile of the cove, covering approximately 100 acres, is separated from Providence River by a small peninsula extending southerly from the mainland to Bullock Point. (See U. S. Coast and Geodetic Survey Chart No. 278.) Existing project. This provides for an entrance channel 8 feet deep and 75 feet wide from deep water in Providence River to a point inside the cove; an inner channel 6 feet deep, 75 feet wide from the entrance channel to a point opposite Haines Memorial Park; a south mooring basin on the west side of the inner channel opposite the boat club, 6 feet deep, about 8.3 acres; a mooring and turning basin at the end of the inner channel, 6 feet deep, about 2.9 acres; and rebuilding the tip of Bullocks Point to a height of 9 feet above mean low water with dredged material retained by a rubblestone dike and jetty. The mean range of tide is about 4.6 feet, and the spring range is about 5.4 feet. The latest approved estimate of Federal cost for new work is $249,000 (July 1957). The existing project was adopted by the following River and Harbor Act: June 30, 1955-8-foot channel; 6-foot turning basin; 6-foot anchorage; and reconstruction of Bullock Point Cove entrance to form a breakwater. (H. Doc. 242, 83d Cong., 2d sess.) Local cooperation. These conditions require that local interests contribute, in cash, 42 percent of the cost of the dredging and con- struction of the stone dike and jetty, presently estimated at $181,000, and give assurances satisfactory to the Secretary of the Army that they will (a) furnish free of cost to the United States all lands, easements, rights-of-way, and suitable spoil-disposal areas for construction and for subsequent maintenance when and as required; (b) construct dikes or other structures required to retain dredged materials placed on spoil areas other than the sandfill area at Bullock Point; (c) provide and maintain a public landing, suitably equipped, open to all on equal terms; (d) hold and save the United States free from damage due to construction and subsequent maintenance of the project; and (e) establish a competent public body to regulate use of the waterway. As- surances of local cooperation have been received from the State of Rhode Island and the two adjacent towns of Barrington and East Providence. A portion of the cash contribution amounting to $136,000 was received in fiscal year 1957 ($10,000 of which is in lieu of (b) constructing dikes or other structures required to retain dredged materials placed on spoil areas other than the sandfill area at Bullock Point). Spoil-disposal areas are in the process of being furnished. The State of Rhode Island's plans for construction of public landing are presently being prepared. Terminal facilities. On the westerly side of Bullock Cove are RIVERS AND HARBORS-NEW ENGLAND DIVISION 51 located two boatyards. Three marine railways of 12-ton, 15-ton, and 25-ton capacity respectively, are available. The two boatyards have supply, repair, and service facilities, and have storage space for approximately 125 boats, and in addition, one yard does considerable business in the construction of custom-designed boats. Adjacent to the boatyards is the Narragansett Terrace Boat Club. The boat club and one of the boatyards maintain piers which are open to the public at the owners' convenience. There are no publicly owned piers or landings on the cove, although there are locations at which such piers could be developed, as there is public access to the cove on both sides as well as some undeveloped land. The plan proposed by local interests includes a public pier at the State-owned Haines Memorial Park. Operationsand results during fiscal year. Operations consisted of engineering studies and preparation of plans and specifications for improvement dredging of an 8-foot channel, a 6-foot anchorage and turning basin, and construction of breakwaters and seawalls. Costs from Federal regular funds during the fiscal year amounted to $12,835, all for new work. Condition at end of fiscal year. Construction of the project has not been initiated. To complete the project there remains improvement dredging of an 8-foot channel, a 6-foot anchorage and turning basin, and construction of breakwaters and seawalls.

This harbor is situated in the southeast corner of Connecticut, and on the north shore of Fishers Island Sound. It is 9 miles east of the entrance to New London Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 358 and 1211.) Previous projects. The original project for Stonington Harbor was authorized by the River and Harbor Act of May 23, 1828, and subsequently modified by the Acts of 1873, 1875, 1880, 1894, and 1896. See Annual Report for 1897. Existing project. This provides for dredging of Penguin Shoal to a depth of 10 feet. The mean tidal range is 2.7 feet; the spring range is 3.2 feet. The Federal cost of new work for the completed project was $39,879, exclusive of amounts expended on previous projects. Dredging of the 6-foot anchorage portion of the project is considered to be inactive and is excluded from the estimate of cost for new work. The cost of this portion was last revised in 1956 and was estimated to be $76,000, of which local interests are required to contribute $5,500. The existing project was authorized by the River and Harbor Act of May 17, 1950. The latest published map is contained in the project document (H. Doc. 667, 80th Cong., 2d sess.). Local cooperation. Fully complied with. Terminal facilities. The harbor has a total frontage of 1.5 miles, one-third of which is developed for commercial use. One municipally-owned pier, 200 feet long, is open to the public as a landing for recreational craft. Four wharves, providing 2,700 lineal feet of berthing space with depths ranging from 5 to 12 feet are in active use for receipt of fish and shellfish. Two boatyards with marine railways, and two engine-repair shops are located in the harbor. Operations and results during fiscal year. Improvement dredging, by contract, to deepen Penguin Shoal to 10 feet was initiated in October and was completed in December except for minor shoals. These shoals were removed in May 1957, completing all work. During the period 28,370 cubic yards of ordinary material were removed. Federal costs during the fiscal year from regular funds amounted to $37,802, all for new work. Condition at end of fiscal year. The project has been completed. Construction was initiated in October 1956 and completed in May 1957. The controlling depths at mean low water were as follows: 11 feet in the Inner Harbor (1946) ; 10.1 feet in the 10-foot Penguin Shoal area (1957). The total Federal costs under the existing project from regular funds amounted to $39,879, all for new work.

CONNECTICUT RIVER BELOW HARTFORD, CONN. Location. This river has its source in Connecticut Lake in northern New Hampshire, flows southerly 380 miles, and empties into Long Island Sound at Saybrook, Conn., 14 miles west of New London. Hartford, now the head of commercial navigation, is 52 statute miles, by channel, from the mouth. (See U. S. Coast and Geodetic Survey Charts Nos. 215, 266, 267.) RIVERS AND HARBORS-NEW ENGLAND DIVISION 57 Previous project. Adopted by the River and Harbor Acts of July 14, 1836, and July 11, 1870. For further details, see page 1754, Annual Report for 1915 and page 120, Annual Report for 1938. Project for Eightmile River, Conn.: Elimination as separate project. This provides for a channel 8 feet deep and 75 feet wide from deep water in the Connecticut River to Hamburg and for turning basin of the same depth, 150 feet wide, approximately 300 feet long at Hamburg. The project was adopted by the River and Harbor Act of June 25, 1910. The costs and expenditures have been $9,000, all for new work. In accordance with the River and Harbor Act of May 17, 1950, the project for Connecti- cut River below Hartford was modified to include the project for Eightmile River, which was eliminated as a separate project. The aforementioned act also provided for an anchorage basin 6 feet deep and about 6.5 acres in area in the upper cove at Hamburg. Existing project. This provides for a channel 15 feet deep at mean low water, 300 feet wide from the mouth to the Lyme rail- road bridge, about 3.4 miles, and thence 150 feet wide to Hart- ford, a total distance of 52 miles, the channel to be obtained by dredging and the construction of dikes, training walls, revet- ments, and the accessory works; for two riprap jetties at the mouth of the river, the tops to be 5 feet above high water and 6 feet wide, the easterly one about 2,300 feet and the westerly about 2,750 feet in length; for a training dike about 3,700 feet long at Hartford, and for anchorage 11 feet deep, about 12 acres, and one, 6 feet deep about 17 acres, in North Cove. Old Saybrook, with an entrance channel 11 feet deep and 100 feet wide; for a channel 8 feet deep, 75 feet wide about 1.5 miles in length from the Connecticut River to Hamburg; a turning basin of the same depth 150 feet wide and 300 feet long at Hamburg. The mean tidal range is 3.5 feet at the mouth, and at summer stage is about 1 foot at Hartford. The maximum tidal range at the mouth due to wind or other causes, is 8 feet or more. At Hartford the usual rise due to spring freshets is between 16 and 24 feet above mean low water. The maximum recorded freshet at Hartford (March 1936) was 35.5 feet above mean low water. Below Middletown the height of the crest of the freshet decreases rapidly. The latest approved estimate of Federal cost for new work is $1,455,984 (July 1957) exclusive of amounts expended on previous projects. The dredging of the 6-foot channel, turning basin and anchorage area at Hamburg to a depth of 6 feet, about 6.5 acres in area in Eightmile River portion of the project is considered to be inactive and is excluded from the foregoing estimate. The Federal cost of this portion was last revised in 1956 and was estimated to be $57,000. The average annual maintenance cost during the past 5 years was $99,195. 58 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The River and Harbor Act of August 30, 1935, authorized the 15-foot channel up to Hartford and addi- tional dikes, training walls, and revetments, subject to provision that local interests shall furnish, free of cost to the United States, suitable areas for the disposal of dredged material during initial construction and for future maintenance as and when needed. Areas have been furnished where required and it is understood that future requirements will be met. The River and Harbor Act approved March 2, 1945, authorized the channel and anchor- ages in North Cove subject to the provisions that local interests contribute in cash $67,500, but not to exceed 50 percent of the initial construction cost and give assurances satisfactory to the Secretary of War that they will provide a suitable public landing in the cove, at an estimated cost of $13,000. It is expected that these conditions will be met. Terminal facilities. On both the Connecticut and Eightmile Rivers there are 2 or 3 wharves at each of the river towns, 1 or more in each town being open to public use. At Hartford and at Middletown there is approximately one-half of wharf frontage along the west bank of the river. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Costs from regular funds for new work in the amount of $428 were incurred during the fiscal year for engineering studies of the Eightmile River por- tion of the project, since declared to be inactive. Maintenance dredging, by contract, to restore the project depth to 15 feet in the 52 miles of river channel by removing river bars between Saybrook and Hartford, Conn., was in progress at the beginning of the fiscal year and completed in September 1956 with the removal of 232,125 cubic yards of material, making a total of 301,290 cubic yards of material removed under the contract. Costs during the fiscal year from regular funds amounted to $204,268 for maintenance. Total costs from all funds during the fiscal year amounted to $204,696. Condition at end of fiscal year. The existing project is about RIVERS AND HARBORS-NEW ENGLAND DIVISION 59 70 percent completed. The 15-foot channel from the mouth to Hartford was completed in 1937. The Saybrook jetties and train- ing walls at Hartford, Clay Banks, and Sears Shoal were com- pleted in 1915. The stone dikes and timber spurs at Pistol Point, Glastonbury, Press Barn, Naubuc, Cys Hollow, and Clay Banks were completed in 1927 and those at Wethersfield, in 1947. Timber pile dikes at Press Barn were completed in 1940 and at Press Barn, Glastonbury (including Two Piers), and Gildersleeve Island reaches have been revetted. The jetties at Saybrook need repairs. The revetments and timber dikes have deteriorated and require repairs. To complete the project requires the construction of addi- tional permanent works, and dredging the channel and anchorage in North Cove, Old Saybrook, Conn. The head of commercial navi- gation is at Hartford, 52 miles by channel from the mouth. A dam at Holyoke, Massachusetts, 34 miles above Hartford, completely interrupts navigation. The controlling depths at mean low water are generally 15 feet to Hartford (1956) ; 1.0 feet in the entrance channel to North Cove (1938) ; 0 feet in anchorage in North Cove (1938) ; 7 feet in channel and basin in Eightmile River (1946) ; 0 to 6 feet in anchorage at Hamburg (1946). The total costs under the existing project from regular funds have been $3,350,977, of which $858,984 was for new work which includes $9,000 of com- pleted new work (existing project) transferred from Eightmile River project, and $2,491,993 for maintenance.

The Patchogue River is a small tidal stream 3 miles long, situated in the town of Westbrook, Conn., on the north shore of Long Island Sound, about 7 miles west of the mouth of the Connecticut River. (See U. S. Coast and Geodetic Survey Chart Nos. 216 and 1212.) Existing project. This provides for a channel 75 feet wide and 8 feet deep extending about one mile from deepwater in Duck Island Roads to the highway bridge on U. S. Route 1; an anchorage and maneuvering area 8 feet deep, 75 feet wide, 500 feet long opposite the town wharf; a sand-tight stone jetty extending 600 60 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 feet southerly into Duck Island Roads from a point on the west side of the mouth of the river. The mean range of tide is 4.5 feet and the spring range is 5.3 feet. The Federal cost of new work for the completed project was $149,895. The existing project was authorized by the following River and Harbor Act: September 3, 1954-8-foot channel; an anchorage and maneuvering area; a sand-tight stone jetty. (H. Doc. 164, 83rd Cong., 1st sess.) Local cooperation. Fully complied with. Total actual costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $100,000. Terminal facilities. There are 5 wharves located along the Patchogue River. The town of Westbrook has constructed on the right bank of the river a free public wharf. It has no boat servic- ing nor transfer facilities. There are 60 feet of wharf space used principally by the local fishing fleet for the transfer of its catch to motor trucks that transport it directly to market. The wharf is of solid-fill construction with rubble-stone sides and earthfill, topped with a bituminous pavement. There are 4 private wharves in the central reach. Two of these, owned by the Standard Fish Co., flank the town wharf on the north and south sides, and are timber and pile construction. The wharf on the south side is a 90-foot marginal landing constructed of planks on 2-pile bents. Adjacent to this wharf is a marine rail- way, capable of handling boats up to 30 feet in length, with storage space for 30 boats. The wharf on the north side is a 35-foot long marginal landing of plank and pile construction with fishhouse attached. This wharf is used principally in the fish and lobster business. Immediately upstream and abutting this wharf is a privately owned 100-foot long marginal wharf of similar construc- tion, which will be used in conjunction with the boatyard. Fuel- handling facilities are installed on the wharf. The remaining private wharf is located on the left bank of the river, immediately below the highway bridge. It is a 180-foot long marginal struc- ture of timber, pile and rubble-stone construction. Dock space is rented at this wharf and there is a building located on the shore adjacent to the wharf, in which a retail and wholesale fish business is operated. There is adequate room for expansion of terminal facilities. Operations and results durinq fiscal year. Construction of a stone jetty at the mouth of the Patchogue River, by contract, was in progress at the beginning of the fiscal year and was completed in July 1956. During the fiscal year approximately 467 tons of stone were placed in the jetty, making a total of 6466.81 tons placed.

The mean range of tide is 6.2 feet at the entrance to the harbor, and 6.3 feet at Long Wharf Light. The latest approved estimate of Federal cost for new work is $4,743,000 (July 1957), exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $55,055. Local cooperation. The 35-foot main channel and the 22-foot channel and turning basin in Quinnipiac River were authorized subject to the conditions that local interests furnish free of cost to the United States all lands, easements, and rights-of-way and suitable spoil-disposal areas for the initial work and for subse- quent maintenance when and as required, and hold and save the United States free from damages resulting from the improve- ment. These requirements, as applied to the 35-foot channel, have been met, and assurances have been furnished that the re- quirements for the 22-foot channel and turning basin in the Quinnipiac River will be met. These assurances were approved by the Chief of Engineers on June 2, 1947. Bulkhead spoil areas for the 35-foot channel cost local interests $160,000. The esti- mated cost to local interests of bulkheads for the construction of the Quinnipiac River 22-foot channel is $50,000. Terminal facilities. The port of New Haven is served by 53 waterfront facilities; 48 are located within the city limits of New Haven, and 5 in West Haven. The improved waterways within the port area along which the facilities are located include the West River, Main Harbor, West and East Branches of Mill River, and the Quinnipiac River channels. These facilities are all pri- vately owned and operated with the exception of the City wharf. Depths alongside the piers and wharves range from 35 to zero feet at mean low water. Nearly half of the facilities have rail connections either on or at the rear which connect with the New York, New Haven, and Hartford Railroad and most all of them are accessible by paved streets. Nineteen of the wharves have mechanical-handling facilities. Six of the wharves are open to public use upon agreement with the owners. Facilities are ade- auate for existing commerce. (For further details, see Port and Terminal Facilities of Southern New England No. 4 revised in 1952.) Operations and results during fiscal year. Maintenance dredg- ing, by contract, to remove shoals in the 35-foot main harbor chan- nel and in the 12-foot West River Channel was initiated in June and was still in progress at the end of the fiscal year. To June 30, 1957, approximately 32,000 cubic yards of ordinary material were removed from the 35-foot channel and 20,000 cubic yards from West River, making a total of 52,000 removed under the contract. RIVERS AND HARBORS-NEW ENGLAND DIVISION 67 Hopper Dredge "Comber" was in operation for 3 weeks in May in the entrance channel. During that time approximately 141,953 cubic yards (pay place plus natural shoaling) of ordinary material were removed by the dredge. Miscellaneous inspections and re- ports were made on the project during the fiscal year. Costs during the fiscal year from regular funds amounted to $187,222, all for maintenance. Condition at end of fiscal year. The existing project is about 88 percent complete. The controlling depths at mean low water were: 31 feet in the middle half, 30 feet in the westerly quarter, and 32 feet in the easterly quarter of the 35-foot channel from 500 feet seaward of the east breakwater to abreast Koppers wharf, thence 30 feet to about 500 feet downstream of the Tomlinson Bridge, thence 16 feet to the bridge (1952); 7 feet generally in West River to Kimberly Avenue Bridge, thence 9.0 feet to up- stream limit of Federal Project about 500 feet above Kimberly Avenue Bridge (1952) ; 12 feet in Brewery Street Channel (1940) ; 18 feet in the Quinnipiac River Channel to Ferry Street Bridge, thence 16 feet to Grand Avenue Bridge (1956), 12 feet in the 12- foot Mill River Channel from 900 feet downstream of the Chapel Street Bridge to the junction of the East and West Branches, 10 feet in the westerly three-quarters and 3 feet in the easterly quarter of the East Branch and 10 feet in the West Branch (1952) ; 0 to 10 feet in the West Haven 6-foot anchorage (1952) ; 16 feet in the 15-foot anchorage (1940) ; 0 to 25 feet in the 16-foot anchor- age (1950). Mill River requires dredging to restore project depths. The 35-foot channel requires dredging to remove shoals and restore project depth. To complete the project requires the dredging of the 22-foot Quinnipiac River Channel and turning basin. The total Federal costs under the existing project from regular funds have been $5,395,534, of which $3,523,536 was for new work and $1,871,998 was for maintenance. National In- dustrial Recovery funds amounting to $290,877 and $59,207 Public Works funds, both for new work, have been expended on the project.

HOUSATONIC RIVER, CONN. Location. Rises in northwestern Massachusetts, flows souther- ly 130 miles through Massachusetts and Connecticut, and empties into Long Island at Stratford, 5 miles east of Bridgeport Harbor. (See U. S. Coast and Geodetic Survey Chart No. 219.) Existing project. This provides for a channel 18 feet deep at mean low water and 200 feet wide from the mouth to the lower end of Culvers Bar, about 5 miles, and thence 7 feet deep and 100 feet wide to Derby and Shelton, about 8 miles; a riprap break- water at the mouth, consisting of an inner arm, 3,250 feet long, 3 feet high above mean low water, top width 6 feet, side slopes 1 on 1, and an outer arm 2,571 feet long, 6 feet high above mean high water, inner slope 1 on 1; riprap dike in the river below Stratford not to exceed 1,500 feet in length; and a riprap jetty 163 feet long at Sow and Pigs Rocks. The mean tidal range, ex- clusive of the winter season and freshets, is 6.7 feet at the mouth, 5.5 feet at Stratford, and 5 feet at Shelton; the extreme range due to combined effect of wind and other causes is about 11 feet at the mouth, diminishing toward the head. The spring freshets occasionally rise to a height of 18 feet or more above summer low water, but only average about 12 feet above that datum. The Federal cost of new work for the completed project was $855,735. The enlargement of the outer arm of the breakwater to provide a top width of 12 feet and an outer slope of 1 on 2, and the exten- sion of the Stratford dike not more than 245 feet long are both portions of the existing project considered to be inactive and are excluded from the foregoing cost estimate.

RIVERS AND HARBORS---NEW ENGLAND DIVISION 69 Operations and results during fiscal year. Improvement dredg- ing under a continuing contract, employing the hydraulic dredging process, of the 18-foot project channel from the mouth of the river to Culvers Bar, in progress at the beginning of the fiscal year, was continued. Work under the contract was completed in September 1956, with the exception of the removal of approximately 4,000 cubic yards of material in the vicinity of the old State of Con- necticut Washington Street highway bridge piers, which could not be accomplished until the highway dredging work and removal of piers had been completed. By agreement, this work is to be done by the State. During the fiscal year approximately 669,463 cubic yards of ordinary material were removed, making a total of 1,975,512 cubic yards removed under the contract. Costs during the fiscal year amounted to $167,867 from Federal regular funds, and $94,557 from contributed funds, all for new work. Condition at end of fiscal year. The existing project has been completed. The 18-foot channel from the mouth of the river to Culvers Bar was completed in September 1956, with the exception of the removal of approximately 4,000 cubic yards of material in the vicinity of the old State of Connecticut Washington Street highway bridge piers, which could not be accomplished until the highway dredging work and removal of piers had been completed. The upriver channels were completed in 1893. The breakwater at the mouth was completed in 1914 except that the outer arm has a top width of 8 feet and outer slope of 1 on 11/2 instead of project dimensions; the Stratford dike was completed to its present length of 1,225 feet in 1916, and the jetty at Sow and pigs Rocks was completed in 1871.

The cost of this work was estimated to be $4,053,000, of which $3,346,000 was Federal and $707,000 was local cash contribution (July 1957). 72 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Local cooperation. Fully complied with. Terminal facilities. There are 35 waterfront facilities serving the port of Bridgeport, all of which are used or in usable con- dition. Numerous handling facilities are predominant in every section of the harbor. Although more than 70 percent of the total number of docks are marginal wharf type structures in constricted waterways, there are, however, several offshore wharf and pier type structures in the open waters of the main harbor. All of the piers, wharves, or docks are accessible by paved road- ways, but only half of them have rail connections with the rail line serving the port area. Three of the wharves are owned by the city of Bridgeport and 3 others may be used by the public upon agreement with the owners or operators. (For further de- tails, see Port and Terminal Facilities of Southern New England, No. 4, revised in 1952.) Operations and results during fiscal year. Maintenance dredg- ing by Government-owned hopper dredge Comber to restore the 30-foot main entrance channel was in progress at the beginning of the fiscal year and was completed on 15 July 1956. During the period 191,598 cubic yards (bin measurement) of ordinary material were removed, making a total of 500,665 cubic yards of material removed by the dredge. Maintenance dredging, by con- tract, to restore project depth in the 30-foot inner harbor channel from a point about 1,300 feet south of the Stratford Avenue Bridge to opposite Bug Light and in the 30-foot turning basin adiacent to east limit and opposite Bug Light was initiated on 15 September 1956 and was completed in October 1956. During the period 131,449 cubic yards of ordinary material were removed. Federal costs from regular funds during the fiscal year amounted to $255.654, all for maintenance. Condition at end of fiscal year. The existing project is com- plete. The east breakwater is in good condition; the west break- water and the shore protection works on Fayerweather Island are in need of repairs.

CONNECTICUT RIVER BASIN, VT., N. H., MASS., AND CONN. Location. The works covered by this project are a series of dams and reservoirs on tributaries of the Connecticut River in Vermont, New Hampshire, and Massachusetts, within a radius of 230 miles from Hartford, Conn., and local protection works at several cities in the basin. Existing project. The Flood Control Act, approved June 22, 1936, as amended by the act approved May 25, 1937 (PL 111, 75th Cong.), authorized the construction of 10 reservoirs on tributaries of the Connecticut River in accordance with plans in House Docu- ment No. 412, 74th Congress, 2d session, as the same may be revised upon further investigation of the 1936 flood. The Flood Control Act, approved June 28, 1938, approved a general comprehensive plan for the control of floods and other pur- poses in the Connecticut River Valley, as set forth in House Docu- ment No. 455, 75th Congress, 2d session, and authorized the sum of $11,524,000 for construction of local flood-protection projects in the plan. The act of October 15, 1940, modified the act of June 28, 1938, to provide addional protection at East Hartford, Conn., as set forth in House Document No. 653, 76th Congress, 3d session. The act of August 18, 1941, modified the comprehensive plan ap- proved in 1938 to include the improvements recommended in House Document No. 653, 76th Congress, 3d session, and House Docu- ment No. 724, 76th Congress, 3d session, with such further modifi- cations as may be found justifiable in the discretion of the Secre- tary of the Army and the Chief of Engineers. The latter act also authorized to be appropriated the additional sums of $6 million for local protection works and $10 million for reservoirs. The act of October 26, 1942 (PL 759, 77th Cong., 2d sess.), further modi- fied the plan by including the construction of Gully Brook conduit at Hartford, Conn. The Flood Control Act, approved December 22, 1944, authorized the expenditure of $30 million in addition to the previous author- ization for the comprehensive plan approved in 1938 and modified the plan by (1) directing specific consideration of an alternative plan of the Vermont State Water Conservation Board instead of the Williamsville Reservoir in the West River Basin, Vt., (2) directing consultation with the affected States during the course of investigations and transmission of the proposal and plans to each affected State for written views and recommendations for reser- voir projects heretofore authorized for construction at Cambridge- port, Ludlow, South Tunbridge, and Gaysville, and resubmission of the projects or modifications thereof to the Congress, and (3) rescinded the authorization for construction at the Sugar Hill site.

HARTFORD, CONNECTICUT RIVER BASIN, CONN. Location. Hartford, Conn., is located in Hartford County on the west bank of the Connecticut River, 52 miles above the mouth. Existing project. The plan of improvement provides for the construction of a system of levees and floodwalls approximately 38,000 feet long, along the Connecticut River from high ground immediately north of town to high ground immediately south of town, with the Park River, which discharges into the Connecticut River at about the center of town, confined between concrete walls discharging through a short conduit section through the Con- necticut River dike, including pumping stations for the disposal of interior drainage. The improvements as planned involved the construction of approximately 4,000 linear feet of concrete flood- wall, 22,000 feet of earth dike, and an enlargement of 12,000 feet of existing dike along the Connecticut River, the construction of 5,600 linear feet of concrete conduit on the Park River, con- struction of 2,400 feet of conduit on Gully Brook, construction of 1,900 feet of conduit on Folly Brook, construction of 5 stop-log structures, 3 pumping stations, and other appurtenant drainage structures and facilities. The project grade for levees and walls was designed to protect against a flood greater than any of record, as modified by an approved plan of reservoirs for flood control in the Connecticut River Basin. The grades at all points were above the maximum stage of the record flood, that of March 1936. At the request of the city of Hartford, the wall and dike grades were increased 5 to 6 feet, the crown width for levees increased from 10 to 15 feet, a conduit provided for the Park River in lieu of the open channel improvement; special equipment provided for the Keney Lane and Bushnell Park pumping stations, and a super- structure of special architectural treatment provided for the Bush- nell Park pumping station. Additional expense of approximately $2,542,500 involved in these changes was borne by the city of Hartford. The existing project was authorized by the Flood Con- trol Act approved June 28, 1938 (H. Doc. 455, 75th Cong., 2d sess.), and modified by the Flood Control Act of August 18, 1941 (H.

INSPECTION OF COMPLETED FLOOD-CONTROL WORKS In accordance with provisions of the Flood Control Act of 1936, as amended, local flood-protection works constructed with Federal funds are transferred to local interests to operate and maintain. To insure compliance with regulations prescribed for their opera- tion and maintenance, regular and periodic inspections of the following projects were made during the fiscal year: Northampton, Mass. Norwalk, Conn. Holyoke, Mass. Springfield, Mass. Springdale, Mass. Hartford, Conn. Riverdale, Mass. East Hartford, Conn. Chicopee, Mass. Winsted, Conn. West Springfield, Mass. Nashua, N. H. Lowell, Mass. At Chicopee, Mass., additional pumping capacity, necessary dur- ing construction of bridge approach to new Massachusetts Turn- pike, was no longer required. Upon completion of the approach, pumping, and appurtenant drainage facilities were removed by the Turnpike Authority and inspection of the area was made by the Corps of Engineers. GENERAL INVESTIGATIONS-NEW ENGLAND DIVISION 135 At East Hartford, Conn., approach fill for a new crossing of the Connecticut River to Hartford was placed. Erection of the super- structure of the new bridge was initiated by the Greater Hartford Bridge Authority in April 1957. Inspection of this work as it affects or modifies the dike and drainage system is being done by the Corps of Engineers as a part of maintenance inspection of Local Protection Works.

This stream empties into a shallow bay in the north shore of East River, 11 miles by water northeast of the Battery, New York City. (See U. S. Coast and Geodetic Survey Chart No. 226.) Previous project. Adopted by the River and Harbor Act of June 3, 1896. For further details, see Annual Report for 1915, page 1762, and Annual Report for 1938, page 166. Existing project. This provides for a channel 10 feet deep at mean low water and 100 feet wide, to extend from deep water in East River to the head of navigation at the dam at East 177th Street, involving the first dredging from East River at Randall Avenue to a width of 200 feet; thence to Spofford Avenue, 150 feet; thence to Watson Avenue, 125 feet; thence to the railroad bridge near Westchester Avenue, 100 feet, except in the southern approach to the bridge, where it is to be 140 feet. The length of the section included in the project is about 2.4 miles. Mean tidal range, 6.9 feet in the estuary; mean range of spring tides, 8.2 feet; irregular fluctuations due to wind and barometric pressure vary from 4 feet below mean low water up to 8.5 feet above mean high water. The cost of new work for the completed active portion of the project as described above was $1,080,910, exclusive of amounts expended under previous projects, and exclusive of $10,000 con- tributed by local interests. The average annual maintenance cost during the past 5 years was $21,800. The channel widening from Westchester Avenue to East 172d Street is considered to be inactive and is excluded from the foregoing description of the existing project and cost estimate. The cost of this portion was last revised in 1953 and was estimated to cost $299,000. The existing project was adopted by the River and Harbor Act of March 4, 1913 (H. Doc. 897, 62d Cong., 2d sess.). For latest published map, see Annual Report for 1912, page 1470. Local cooperation. The River and Harbor Act of March 4, 1913, provides that any right-of-way that may be necessary for the execution of the project shall be furnished free of cost to the United States. Right-of-way within the bulkhead lines below the Westchester Avenue Bridge was accepted by the Chief of Engi- neers under date of June 9, 1920, and above the Westchester Avenue Bridge under date of October 4, 1928. Under date of September 10, 1940, the Chief of Engineers approved releases from damages furnished by adjoining property owners in the reach of the river between Westchester Avenue and East 174th Street. Under date of November 12, 1940, the Chief of Engineers approved an agreement under which the city of New York would reimburse the United States for the cost of a retaining wall to protect adjoining property in the reach of the river between Westchester Avenue and New York, New Haven & Hartford railroad bridge in lieu of furnishing additional right-of-way. On October 28, 1940, the Secretary of War authorized the acceptance of $10,000 from the city of New York to defray the cost of the RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 139 retaining wall. The $10,000 was deposited to the credit of the United States on December 7, 1940. Additional right-of-way required in the section below East 172d Street has not been furnished. The city of New York has indicated that it does not feel justified in acquiring any additional land along the river. Terminal facilities. There are 17 terminals with 3,600 feet of bulkheads and wharves available for dockage, located along the east and west banks from Randall Avenue to East 173d Street. One of the terminals is publicly owned. Five of the terminals are equipped with mechanical handling devices. Additional terminals with modern facilities will be needed when the existing project is developed. Operations and results during fiscal year. The U.S. Derrick Boat Babcock, and attendant plant, were employed from July 11, 1956, to September 27, 1956, and on November 3, 1956, in dredging shoals in the vicinity of Randall Avenue and for the removal of two abandoned wrecks. During the fiscal year, 40,300 cubic yards, place measurement, of material were removed at a cost of $109,000, including $120 for engineering preliminary to dredging for maintenance. Condition at end of fiscal year. The existing project was about 82 percent completed. A channel to project dimensions was completed from deep water in East River up to the Westchester Avenue Bridge in 1926. A channel 10 feet deep and 65 to 123 feet wide from Westchester Avenue Bridge to East 174th Street was completed in 1941. When examined in September-October 1956, the controlling mean low water depth was 10 feet for a width varying from 50 to 100 feet from East River to 800 feet south of Bruckner Boulevard Bridge, thence 8 feet for a width varying from 50 to 60 feet to 800 feet south of Westchester Avenue Bridge, thence 6 feet for a width varying from 30 to 100 feet to the New York, New Haven & Hartford railroad bridge. The work remaining to be done under existing project consists of widening to project width the reach between Westchester Avenue Bridge and East 172d Street. The channel between East 172d Street and the upper limit of the authorized project is in process of being filled in by the city of New York under a Department of the Army permit, and is no longer a waterway.

LONG ISLAND INTRACOASTAL WATERWAY, N. Y. Location. This waterway extends from East Rockaway Inlet, on the south side of Long Island, to Great Peconic Bay at the eastern end of Long Island. The section included under this project extends from Great South Bay opposite Patchogue to the south end of Shinnecock Canal. (See U. S. Coast and Geodetic Survey Chart No. 578.) Existing project. This provides for a channel 100 feet wide and 6 feet deep at mean low water from the federally improved channel in Great South Bay, opposite Patchogue to the south end of Shinnecock Canal. The length of the section included in the project is 34 miles. The mean tidal range varies from 1.0 foot in Shinnecock Bay to 0.7 foot in Patchogue Bay; mean range of spring tides varies from 1.2 feet to 0.8 foot; irregular fluctua- tions due to wind and barometric pressure vary from 1.8 feet below mean low water to 12.0 feet above mean high water. The cost for new work for the completed project was $235,964. The average annual maintenance cost during the past five years was $18,454. The existing project was adopted by the River and Harbor Act of August 26, 1937 (H. Doc. 181, 75th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Fully complied with except that local interests are required to furnish suitable spoil-disposal areas for subsequent maintenance as required. Terminal facilities. There are 17 boat repair and storage yards within the area immediately adjacent to the Federal im- provement. There is ample room for expansion and development of terminals when future commerce warrants. Operations and results during fiscal year. Under a contract for dredging to restore a depth of 6 feet in the vicinity of Moriches Inlet, Ponquogue Bridge and the Shinnecock Canal, work was commenced on April 29, 1957 and completed on June 10, 1957. During the fiscal year, 90,447 cubic yards, place measurement, of material were removed at a total cost of $54,333, including $2,603 for engineering preliminary to dredging for maintenance. Condition at end of fiscal year. Work under the existing project was commenced October 1939 and completed September 1940. When examined in October 1953, August 1955, and May 1957, the controlling mean low water depth in the channel was 5 feet for a width varying from 100 to 50 feet, except in the reach from Speonk Point to West Bay Bridge, where the con- trolling depth was 4 feet for a width of 100 feet and in the reach from Ponquogue Bridge to the south end of Shinnecock Canal, where it was 4.9 feet. The total cost of the existing project to June 30, 1957 was $419,406, of which $235,964 was for new work, and $183,442 for maintenance. RIVERS AND HARBORS-NEW YORK, N.

FIRE ISLAND INLET, N. Y. Location. Fire Island Inlet is situated on the south shore of Long Island, about 50 miles by water south and east of the Battery, New York City. It is the main entrance into Great South Bay from the Atlantic Ocean. (See U. S. Coast and Geodotic Survey Chart No. 578.) Existing project. This provides for the construction of a jetty extending generally southwest and south for a length of 5,000 feet from high ground on Democrat Point at the west end of Fire Island, and a channel 10 feet deep and 250 feet wide from deep water in the ocean to deep water within the inlet. Mean tidal range at ocean and inlet ends of Democrat Point are 4.1 and 2.6 feet, respectively. Irregular fluctuations due to wind and baro- metric pressure vary from 2.5 feet below mean low water up to 2.6 feet above mean high water. The cost for new work for the completed project was $594,355, exclusive of $90,190 contributed by local interests. The average annual maintenance cost during the past 5 years was $24,133. The existing project was authorized by the following: Acts Work authorized Documents Aug. 26, 1937 Construction of jetty---- Rivers and Harbors Committee Doec. 33, 75th Cong., 1st sess. May 17, 1950 Channel 10 feet deep H. Doc. 762, 80th Cong., 2d sess. (contains latest published map). Local cooperation. The River and Harbor Act of May 17, 1950, provides that local interests shall: a. Furnish free of cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas necessary for the new work and subsequent maintenance, when and as required. b. Hold and save the United States free from any damages resulting from the improvement. The requirements under the acts of August 26, 1937 and May 17, 1950 have been fully complied with. Terminal facilities. No terminals are within the area im- mediately adjacent to the Federal improvement. There are 42 commercial and pleasure boating terminals with a total berthage of 15,935 feet located at Patchogue, Sayville, West Sayville, Islip, and Bay Shore. In addition, 49 boat repair and storage yards are located along the shores of Great South Bay and adjacent creeks. 142 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The facilities are ample for present and probable future needs. There is room for expansion should future commerce warrant. Operations and results during fiscal year. The U.S. seagoing hopper dredge Hyde and attendant plant were employed inter- mittently from April 29, 1957 to May 15, 1957, in dredging to restore the project channel to a depth of 10 feet. During the fiscal year 42,300 cubic yards, place measurement, of material were removed at a total cost of $38,672, including $4,077 for engineering preliminary to dredging for maintenance. Condition at end of fiscal year. Work under the existing project was commenced June 1939. The jetty was completed in 1941 and in view of the fact that a survey made in November 1953, revealed the existence of a channel with dimensions sub- stantially the same as those authorized, work under the existing project was considered complete as of November 1953. When last examined in March 1957, the controlling mean low water depth was 10 feet for a width of 250 feet from deep water in the ocean to deep water within the inlet. The jetty has surpassed its capacity as a sand entrapping agent and when examined in October 1953, was found to be in fair condition. The total cost of the existing project to June 30, 1957, was $807,436-$594,355 United States funds, and $90,190, contributed funds--a total of $684,545 for new work and $122,891 for maintenance.

JONES INLET, N. Y. Location. This is a small inlet on the south shore of Long Island connecting Hempstead Bay with the Atlantic Ocean. It is 37 miles by water southeast of the Battery, New York City. (See U. S. Coast and Geodetic Survey Chart No. 579.) Existing project. This provides for an entrance jetty and a channel 12 feet deep and 250 feet wide, from that depth in the ocean through the inlet to the Loop Causeway Bridge over Long Creek. The length of section included in the project is about 2.1 miles. The mean tidal range varies from 4.2 feet at the ocean entrance to 3.1 feet at the Loop Causeway Bridge; the mean range of spring tides varies from 5.0 feet to 3.7 feet, respectively; irregular fluctuations due to wind and barometric pressure vary from 3.9 feet below mean low water up to 8.5 feet above mean high water. The estimate of cost for new work is $1,780,000 (July 1957) RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 143 exclusive of $1,780,000 (one-half of total cost) to be contributed by local interests. The existing project was adopted by the River and Harbor Act of March 2, 1945 (H. Doc. 409, 77th Cong., 1st sess.). For latest published map see project document. Local cooperation. The River and Harbor Act of March 2, 1945, provides that local interests shall- a. Contribute 50 percent of the first cost of the improvement. b. Furnish assurances satisfactory to the Secretary of War that they will provide free of cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas needed for the initial work and subsequent maintenance, when and as required. c. Hold and save the United States free of claims for damages resulting from the improvements. d. Provide and maintain a channel 12 feet deep and generally 200 feet wide from the Loop Causeway Bridge over Long Creek to the head of navigation in Freeport Creek at Mill Road. Assurances of compliance with the above conditions were ac- cepted by the Secretary of the Army on April 15, 1953. Authority was also granted by the Secretary of the Army on September 16, 1952, to accept an advance of funds amounting to $2,000,000 offered by the State of New York, the county of Nassau and the town of Hempstead to carry out the improvement at this time. The total sum of $3,615,000, $1,807,500 advanced and $1,807,500 contributed, was deposited to the credit of the United States. Terminal facilities. Within the area tributary to Jones Inlet there are a number of privately owned small wharves and 40 boat repair and storage yards. The latter are equipped for the repair of pleasure craft and fishing vessels. In addition, there are nine public wharves open to the public free of charge, with a total dockage of 2,180 feet. Additional terminals would have to be constructed for the receipt of commercial freight in any sizable quantity. Operations and results during fiscal year. Under a contract for construction of a stone jetty at the entrance to the inlet, work was commenced November 18, 1953 and was in progress at the end of the fiscal year. During the fiscal year 618,454 cubic feet, solid measure, of stone were placed at a cost of $584,185 for new work. Under contract for dredging the inshore channel of Jones Inlet between Point Lookout and the Loop Causeway Bridge to a depth of 12 feet, work was commenced on September 4, 1956, and completed on December 13, 1956. During the fiscal year, 247,397 cubic yards, place measurement, of material were removed at a total cost of $147,365, including $4,908 for engineering preliminary to dredging for new work. The U. S. seagoing hopper dredge Hyde, and attendant plant, were employed during the period September 5, 1956 to November 16, 1956, in dredging the outside channel to a depth of 12 feet from the Atlantic Ocean to Point Lookout. During the fiscal year, 86,800 cubic yards, place measurement, of material were removed at a total cost of $155,130, including $541 for engineering preliminary to dredging for new work. The total cost was $886,680 for new work. 144 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Condition at end of fiscal year. Construction of the project is about 94 percent complete. When examined in August through December 1956, and June 1957, the controlling depths were 12 feet for a width of 250 feet from the ocean to Point Lookout, thence 12 feet for widths varying from 250 feet to 190 feet to the Loop Causeway Bridge. The work remaining to be done under the existing project consists of completion of the jetty. The total costs of the existing project to June 30, 1957, was $3,331,373-$1,475,000 United States funds, $1,664,468 contri- buted funds, and $189,345 advanced funds, a total of $3,328,813 for new work and $2,560 for maintenance.

It is 10 miles east of Rockaway Inlet and about 27 miles by water south and east from the Battery, New York City. (See U. S. Coast and Geodetic Survey Charts Nos. 579 and 1215.) Existing project. This provides for a channel 12 feet deep at mean low water and 250 feet wide from the 12-foot contour in the Atlantic Ocean to the 12-foot contour in Long Beach Channel, a distance of about 0.6 mile, protected by a jetty. Mean tidal range, 4.1 feet; mean range of spring tides, 4.9 feet; irregular fluctua- tions due to wind and barometric pressure vary from 4.1 feet below mean low water up to 5.2 feet above mean high water. The cost of new work for the completed active portion of the project as described above was $503,969 (excluding $100,000 contributed funds). The average annual maintenance cost during the past 5 years was $64,728. The west jetty portion of the project is considered to be inactive and is excluded from the foregoing description of the existing project and the cost estimate. The cost of this portion was last revised in 1954, and was estimated to be $806,000. The existing project was adopted by the River and Harbor Act of July 3, 1930 (H. Doc. 19, 71st Cong., 1st sess.). The latest published map is in the project document. Local cooperation. The River and Harbor Act of July 3, 1930, provides that local interests shall contribute $100,000 to the cost of the work; give assurances satisfactory to the Secretary of War and the Chief of Engineers that they will provide and maintain at their own expense interior channels suitable for navigation, not less than 12 feet deep, from East Rockaway Inlet to the Hempstead-Oyster Bay line, a distance of about 15 miles, to Hewlett Harbor and to Freeport Harbor; furnish, without expense to the United States, necesary land, easements and rights-of-way for construction and maintenance of the jetties, and agree to hold and save the United States free of claims for damages to public and private property resulting from the improvement. Assurances of compliance with the conditions of local coopera- tion precedent to construction of entrance channel and east jetty were approved by the Chief of Engineers and Secretary of War on July 14 and 15, 1932, respectively. Local contribution of $100,000 was deposited to the credit of the United States on August 23, 1932. Since the construction of the west jetty is not considered necesary at this time, easements, rights-of-way, and release of claims for damages necessary for construction are not being secured. Terminal facilities. There are 33 terminals in Oceanside, Island Park, Long Beach, and East Rockaway. Eight of these are oil terminals-6 at Oceanside, one of which has a railroad spur, and 2 at Island Park. The other terminals consist of repair and mooring docks with a berthage of 3,150 feet. Of these 14 have marine railways and 1 has mechanical handling facilities. There are public wharves at East Rockaway and Woodmere, and the 146 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 waterfront on the north side of Long Beach has been bulkheaded. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. The U. S. sea- going hopper dredge Hyde and attendant plant were employed intermittently from June 22, 1956 to July 12, 1956, and April 15, 1957 to May 9, 1957 in dredging to restore the project channel to a depth of 12 feet. During the fiscal year, 42,500 cubic yards, place measurement, of material were removed at a total cost of $62,294, including $1,250 for engineering preliminary to dredging for maintenance. Condition at end of fiscal year. Work under the existing project was commenced February 1933, and is about 85 percent complete. The east jetty, 4,250 feet long, was completed in July 1934. The project channel was completed in May 1935. When examined in May 1957, the controlling mean low water depth through the channel from deep water in Atlantic Ocean to deep water in East Rockaway Inlet was 12 feet for a width of 250 feet. The east jetty was in good condition. The work remaining to be done under the existing project consists of building a west jetty, if necessary, to protect the channel. The total cost of the existing project to June 30, 1957 was $1,088,492--$421,369 from regular funds and $82,600 from Public Works funds, a total of $503,969 for new work and $584,523 from regular funds for maintenance. In addition, the costs from contributed funds were $100,000 for new work.

JAMAICA BAY, N. Y. Location. This is a bay inside the south shore of Long Island, the entrance being about 17 miles by water south and east of the Battery, New York City. (See U. S. Coast and Geodetic Survey Chart No. 542.) Previous projects. Adopted by the acts of June 14, 1880, and July 13, 1892. For further details, see page 1770 of Annual Report for 1915, and page 185 of Annual Report for 1938. Existing project. This provides for an interior channel ex- tending from the vicinity of the Marine Parkway Bridge along the west and north shores of the bay, 18 feet deep at mean low water and 300 feet wide to Mill Basin, with a swinging basin, 1,000 feet wide and 1,000 feet long at that point; thence 12 feet deep and 200 feet wide to Fresh Creek Basin; and interior channel extending from the same locality along the south shore to Head of RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 147 Bay, 15 feet deep and 200 feet wide; a channel in Mott Basin, 15 feet deep and 200 feet wide extending from the channel along the south shore, 3,000 feet to the junction of the two branches, thence 2,200 feet in the north branch (Inwood Creek) and 3,200 feet in the south branch; and an entrance channel connecting the two interior channels with deep water in the Atlantic Ocean, of suitable hydraulic dimensions to maintain the present tidal prism in the bay, but not less than 18 feet deep and 500 feet wide from opposite Barren Island to Rockaway Point, thence enlarging to not less than 20 feet deep and 1,000 feet wide to sea, protected by one riprap jetty. Length of section included in project is 19.7 miles. Mean tidal range, 4.9 feet at Barren Island, and 5.1 feet at Head of Bay; mean range of spring tides, 5.9 and 6.1 feet, respectively; irregular fluctuations due to wind and barometric pressure vary from 4 feet below mean low water to 4.9 feet above mean high water. The estimate of cost for new work is $5,351,000 (July 1957), excluding amounts expended on previous projects but including $4,228,439 expended for new work under River and Harbor Act of June 25, 1910. The average annual maintenance cost during the past 5 years was $9,422. The existing project was authorized by the following: Acts Work authorized Documents June 25, 1910 Construction of 1 jetty. ------------------------ H. Doc. 1488, 60th Cong., 2d sess.

Local cooperation. The River and Harbor Act of March 2, 1945, provides that in lieu of conditions heretofore prescribed, local interests shall furnish free of cost to the United States, suitable areas for the disposal of dredged materials for new work and subsequent maintenance, when and as required, and shall hold and save the United States free from claims for damages resulting from the improvement. The city of New York was notified of the conditions of local cooperation in letter dated January 25, 1946. In letter dated February 7, 1946, the mayor of the city of New York advised that disposal areas are available and that the necessary document "holding the United States free from claim for damages" would be executed. The River and Harbor Act of May 17, 1950, provides that local interests shall: a. Furnish free of cost to the United States all lands, easements, rights-of-way, and suitable areas for disposal of dredged material during construction of the project and for subsequent maintenance, as and when required. b. Hold and save the United States free from damages due to the construction works and subsequent maintenance. 148 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 c. Perform all necessary alterations to the existing terminals and bulkheads, and dredge adequate approaches thereto. These conditions have not been fulfilled. Terminal facilities. There are 40 terminals with a total available berthage of 16,493 feet located along the shores of Jamaica Bay, most of which are concentrated at two general localities; Mill Basin on the west shore, and from Seaside to and including Head of Bay on the south shore. Two of the terminals are available for public wharfage; none has direct rail connections. Nineteen yacht clubs and 18 boatyards, equipped with marine railways, are located within the bay. In addition, there are a number of small landings for pleasure craft. The existing facilities are considered adequate for existing commerce. Operations and results during fiscal year. Under a contract for repair of the jetty, work was commenced on November 9, 1956, and completed on November 20, 1956. During the fiscal year 394.3 tons of stone were placed in the jetty at a total cost of $15,594, including $539 for engineering preliminary to repairs for maintenance. Condition at end of fiscal year. Work under the existing project was commenced August 1912 and is about 87 percent complete. The westerly interior channel from Barren Island to Fresh Creek Basin and the swinging basin at Mill Basin have been dredged to project dimensions. No new work dredging of the entrance channel was done, since depths were greater than those required under the project. The east jetty, completed August 4, 1933, for a total length of about 8,400 feet, was in good condition when examined in August 1953. The controlling mean low water depths of the channels included in this project are as follows: Section Depth Width Date (feet) (feet) Entrance channel: From Atlantic Ocean to Rockaway Point ....... 20 1,000 June 1952.

The length of the waterfront along both shores of the Harlem River is about 16 miles, of which 4 miles are unavailable for commercial use. There are 52 terminals with a total available berthage of 17,865 feet. Thirty of the terminals are owned by the city of New York. Twenty-four of the terminals are equipped with mechanical handling devices and 13 have railroad connections. In addition, there are 5 railroad float bridges. The terminal facilities are considered adequate for present needs. Operations and results during fiscal year. The U.S. Derrick Boat Babcock and attendant plant were employed from November 3, 1956 to November 16, 1956, in the removal of a shoal in the vicinity of the Macombs Dam Bridge to a depth of 15 feet. During the fiscal year, 1,410 cubic yards, place measurement, of material were removed at a total cost of $10,000, including $597 for engineering preliminary to dredging for maintenance. Condition at end of fiscal year. Work under the existing project-was commenced January 1888, and was substantially com- pleted May 1938. Remaining widening to be done in the section above High Bridge is prohibited by the proximity of bulkheads to the channel line. The present width is considered adequate for navigation. No further improvement is contemplated under the project. A channel 15 feet deep at mean low water and 400 feet wide has been excavated from East River to High Bridge, thence 15 feet deep and 350 to 400 feet wide to the Hudson River. The RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 153 rock cut through Dyckmans Meadow was completed to 18-foot depth and 350-foot width in 1896. The straightening of the chan- nel at Johnson Iron Works was completed to 15-foot depth and 400-foot width in 1938. The controlling depth from East River to Hudson River, as shown by examination made in December 1949 and June 1954 was 13.5 feet at mean low water through a navigable channel varying from 120 to 400 feet in width, except for a shoal in the vicinity of Broadway Bridge having a minimum depth of 11 feet and scattered shoals between Sherman Creek and 207th Street Bridge having a minimum depth of 10 feet. The total cost of the existing project to June 30, 1957, was $3,877,676-$3,595,119 for new work and $282,557 for maintenance.

RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 155 Operations and results during fiscal year. The U. S. seagoing hopper dredge Chester Harding and attendant plant were em- ployed intermittently from September 4, 1956 to September 29, 1956 and from February 7, 1957 to March 14, 1957, in dredging to restore the channel along the Weehawken-Edgewater waterfront to a depth of 30 feet. During the fiscal year 275,700 cubic yards, place measurement, of material were removed at a total cost of $185,350 including $2,854 for engineering preliminary to dredging for maintenance. Condition at end of fiscal year. Work under the existing project was commenced April 1913 and was completed in Septem- ber 1952. The work of widening and deepening Weehawken- Edgewater Channel to project dimensions was completed in August 1937. The work of widening the 40-foot channel for the full width of the river from Ellis Island to West 59th Street, Manhattan, was completed in March 1939. The work of widening the 48-foot project to full project width of 2,000 feet from West 40th Street to West 59th Street was completed in November 1950. Deepening of the 45-foot channel for a width of 2,000 feet from Upper Bay to West 40th Street was completed to project dimensions in September 1952.

This river has its source in the Adirondack Moun- tains, about 250 miles in a direct line and 315 miles along its course from the Battery, New York City, and flows in a generally southerly direction into New York Bay. The section under improvement extends from New York City to Waterford, a dis- tance of about 156 miles. (See U. S. Coast and Geodetic Survey Charts Nos. 282, 283, 284, 747, and 748.) Previous projects. The original project for improvement by the United States was adopted by River and Harbor Act of June 30, 1834, and modified in 1852 and 1866. A second project was adopted by River and Harbor Act of July 13, 1892, and modified in 1899. For further details, see page 1764, Annual Report for 1915, and page 226, Annual Report for 1938. Existing project. This provides for a channel 600 feet wide from New York City to Kingston and thence 400 feet wide to Albany, with widening at the bends, a turning basin 700 feet wide and 1,200 feet long at Albany, and 2 anchorages, 1 near Hudson and 1 near Stuyvesant, each with a width of 400 feet and an average length of 2,400 feet; all with depths of 32 feet in soft material and 34 feet in rock; thence 14 feet deep at lowest low water and generally 400 feet wide to the Federal lock at Troy; and thence of same depth and 200 feet wide to the southern limit of the State barge canal at Waterford; and removal of State dam at Troy and the construction of a lock and dam about 21/2 miles below Waterford. The channel is to be formed by dredging and rock excavation, and to be maintained by dredging and by constructing new, and raising and repairing old, longitudinal dikes, built partly under previous projects and partly by the State of New York. The mean range of pool elevation above the Federal dam at Troy, in seasons of moderate rains, is about 2.2 feet, as determined in 1934. The mean tidal range is about 4.7 feet at the Federal dam at Troy and about 4.6 feet at Albany, extreme range due to freshets is 33 and 25.7 feet, respectively. The normal pool level above the Federal dam from Troy to Waterford is 14.33 feet above mean sea level at Sandy Hook, N. J. In the tidal section of the river below the dam the assumed lowest low water plane from Troy to Albany is 3 feet below mean sea level at Sandy Hook, N. J.

S. ARMY, 1957 Terminal Facilities The piers and other terminal or transfer facilities served by the improvement are as follows: Between Waterford and the Federal dam at Troy there are 14 wharves aggregating approximately 5,000 feet in length. The State of New York has constructed a barge-canal terminal at Cohoes. There is a dock 325 feet long on the west side of the river just north of the Federal dam. At Troy there are 9 terminals with available dockage of 2,383 feet, including the State barge-canal terminal with 960 feet. In addition, 11/4 miles of concrete bulkhead were constructed along the waterfront by the city of Troy. At Watervliet there is a stone bulkhead 755 feet long. Between this point and Albany there are 5 timber wharves aggregating 4,275 feet in length. At Albany, and Rensselaer on the east side of the river, there are 30 terminals aggregating 18,661 feet of available berthage, including a city-owned recreation pier of 900 feet and the State barge-canal terminal with 1,586 feet located on the west side of the river. These terminals are adequately served with railroad trackage. There are 5 transit sheds, 1 warehouse, a 13,500,000 bushel grain elevator, and a molasses-storage plant, all provided by the Albany Port District Commission. Between Albany and Hudson there are about 100 timber wharves aggregating 36,700 feet in length; at Hudson there are 12 timber wharves aggregating 5,000 feet in length; at Athens there are 9 timber wharves aggregating 4,000 feet in length. Between Hudson and the upper limits of New York City the entire waterfronts of Poughkeepsie, Newburgh, and Yonkers are equipped with transfer facilities. At Poughkeepsie there are 14 terminals with available dockage of 7,823 feet, including a city- owned pier of 270 feet. At Newburgh there are 17 terminals with a total dockage of 8,431 feet, of which 1 with 90 feet of dockage is open to the public. At Yonkers there are 28 terminals with dockage of 10,659 feet, of which 531 feet are for public use. The existing wharves are ample for Hudson River traffic. Operations and results during fiscal year. By use of Govern- ment plant and hired labor, brush and small trees growing on 60,721 linear feet of dikes were sprayed during the period May 27, to June 17, 1957. In addition Government plant and hired labor were employed intermittently from July 2, to October 31, 1956 and from May 23, to June 28, 1957 on repairs to Schodack (N.Y.S.) Dike and Base Island Dike at a total cost of $31,162 for maintenance. By use of Government plant and hired labor, stumps and snags which formed a potential menace to navigation and other ob- structions were removed from the shores and channel of the river during the fiscal year at a cost of $26,668 for maintenance. The cost of surveys, tidal observations, engineering and surveys pertaining to maintenance operations and contingencies was $26,649 for maintenance. The lock and dam in the Hudson River at Troy, New York, was operated and maintained during the fiscal year. Operation of the RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 159 lock for the 1956 navigation season was suspended on December 17, 1956, and resumed April 5, 1957 for the 1957 season. Derrickboat H. R. No. 1 was employed December 12 to 28, 1956 in removing fender booms and installing pumping equipment and emergency dams, and March 20, to April 17, 1957 in removing emergency dams and pumping equipment and replacing fender booms. The total cost of work was $281,927-$84,479 for Maintenance and $197,448 for operation and care of lock and dam at Troy, New York. Condition at end of fiscal year. Work under the existing project was commenced July 1910 and is about 61 percent complete. The construction of a new lock and dam at Troy, removal of old dam at Troy, and construction of 15,545 linear feet of dikes have been completed. In the reconstruction of old dikes, 39,672 linear feet have been raised to the adopted crest height. The channel from Albany to Waterford has been completed to a depth of 14 feet, with the exception of a small part of the widening to form a harbor at Troy, which work is not deemed necessary for the present. The work of deepening the channel south of Albany to 27 feet mean low water has been completed with the exception of about 1,500 linear feet at the northern end. The controlling mean low water depth from New York City to Hudson is 27.0 feet for a width varying from 270 to 400 feet thence 26.5 feet for a width varying from 170 to 400 feet to about 4,700 feet below the Dunn Memorial Bridge, thence 15.6 feet for a width varying from 190 to 400 feet to the Dunn Memorial Bridge. The controlling lowest low water depth from Albany to the lock and dam at Troy is 13.5 feet for a width varying from 400 feet at Albany to 45 feet near the south entrance to the lock at Troy. At the lock entrance it is 14 feet deep for a width of 45 feet. Con- trolling depth over the lock sills is 13 feet at the lower sill. The controlling pool level depth above the lock at Troy to Waterford, the head of the improvement, is 14 feet for a width varying from 45 feet to 200.feet. The work remaining to be done under the project consists of the construction and reconstruction of dikes, and deepening of the channel from New York City to Albany to 32 feet, construction of the turning basin at Albany, and construction of the anchorages at Hudson and Syuyvesant.

This waterway consists of that portion of the New York State Barge Canal system extending from the Hudson River at Waterford to Oswego Harbor on Lake Ontario. (See U. S. Lake Survey Charts Nos. 183, 184, and New York Canal Charts.) Existing project. This provides for the allotment of Federal funds to the State of New York for expenditure under suitable Federal control and supervision in the improvement of the canal connecting Lake Ontario with the Hudson River. The improve- ment provides for a depth of 13 feet below normal pool level through all locks between Waterford and Oswego, deepening be- tween locks to 14 feet below normal pool level, widening at bends and elsewhere, and increasing the overhead clearance to 20 feet at maximum navigable stage at bridges and other overhead struc- tures. The widths of channel to be provided under the project are 104 feet in earth cuts, 120 feet in rock cuts, 200 feet in river sec- tions, with widening at bends and elsewhere as may be necessary. The length of the waterway included in this project is about 184 miles, of which 160 miles are in the Erie Canal from Waterford to Three Rivers Point and 24 miles are in the Oswego Canal from Three Rivers Point to Oswego. The estimated cost for new work is $38,950,000 (July 1957), of which not more than $27,000,000 shall be expended on deepening between locks and raising of bridges and other overhead clearances Acts Work authorized Documents May 28, 19351 Deepening between the locks to 14 feet, increasing Rivers and Harbors Committee, 2 Aug. 30, 1935 overhead clearances to 20 feet and widening at Doc. 20, 73d Cong., 2d sess. bends and elsewhere. 2 Mar. 2, 1945 Depth of 13 feet below normal pool level through all S.

No estimate of maintenance with Federal funds is included, as maintenance of the canal is not a part of the Federal project. Local cooperation. The River and Harbor Act of March 2, 1945, authorized the deepening of the locks subject to the condition that an agreement be entered into between the United States and the State of New York embodying certain limitations and provisions to safeguard the interests of general commerce and navigation, insure Federal control of the disposition of Federal funds, and provide for Federal supervision of the work performed. A supple- mental agreement dated June 5, 1947, containing all provisions necessary for efficient prosecution of the improvement, was entered into by the Chief of Engineers and the Department of Public Works, State of New York. The requirements under the prior acts have been fully complied with. Terminal facilities. The State of New York has provided ter- minal and transfer facilities at all important points along the Erie and Oswego Canals, and at Buffalo, Troy, Albany, and New York Harbor. The freight-handling equipment, as well as the storage and dock facilities, is governed by the requirements of the par- ticular locality. The State-owned terminal at Oswego has a grain elevator with a capacity of 1,000,000 bushels. The Albany Port District Commission has erected a grain elevator at Albany with a capacity of 13,500,000 bushels. The Port of New York Authority grain terminal in New York Harbor on Gowanus Bay has a capacity of approximately 1,800,000 bushels. Terminals at Buffalo, Rochester, Syracuse, Schenectady, Troy, Albany, and Oswego are provided with direct railroad connections. All State-owned terminals are open to the public on equal terms. Lakeport terminals are extensive in character. The available terminals appear ample to meet all requirements. Operations and results during fiscal year.

Fully complied with as required by the River and Harbor Act approved January 21, 1927, except that local interests are required to provide suitable spoil-disposal areas for maintenance dredging in the 30-foot channel in the Hackensack River above Central Railroad of New Jersey bridge; in the 10-foot channel in the Passaic River; and whenever required by the Secretary of War, for dredging in the 30-foot channel in Newark Bay and the Hackensack River below the Central Railroad of New Jersey bridge, as required by the River and Harbor Act approved September 22, 1922. The River and Harbor Act of March 2, 1945, provides that local interests shall: a. Agree to furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas needed for new work and subsequent maintenance, when and as required; b. Hold and save the United States free from claims for dam- ages resulting from the improvements; c. Provide and maintain suitable berthing areas at Port Newark terminal. 174 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Assurances providing compliance with the local cooperation requirements under this act were accepted by the Chief of Engi- neers on March 22, 1950. In addition, the sum of $285,600 was contributed by the Port of New York Authority to cover the cost of dredging the berthing areas at Port Newark Terminal, which work was completed by the United States in conjunction with the excavation of the project channel during 1951. It further provided, for the 10-foot channel in Passaic River from Montclair & Greenwood Lake Railroad bridge to the Eighth Street Bridge in Passaic, that when spoil-disposal areas are not available, or the placing of dredge spoil ashore is uneconomical as compared with other methods of disposal, local interests shall not be required to furnish disposal areas for maintenance dredg- ing. The River and Harbor Act of September 3, 1954, further provides that local interests shall agree to: a. Furnish, without cost to the United States, all lands, ease- ments, rights-of-way, and suitable spoil-disposal areas for initial construction, and for subsequent maintenance when and as re- quired; b. Provide depths commensurate with the channel depth in ap- proaches and berths at the terminals of the companies which would use the improvement; and c. Hold and save the United States free from damages due to construction and maintenance of the improvement. Terminal facilities. Along the waterways of this project there are 142 terminals with a total berthage of 58,276 feet as well as a large shipyard. Of these, Port Newark, which is owned and operated by the New York Port Authority, provides about 10,625 feet of wharfage. Fifty-seven of the terminals are equipped with mechanical-handling devices and 54 have railroad connections. Six of the terminals aggregating a berthave of 1,789 feet are not used for waterborne commerce. These facilities are considered adequate for existing commerce.

SUPERVISION OF NEW YORK HARBOR Supervisor: Col. T. DeF. Rogers, United States Army from 10 Dec. 1956. The laws enacted for the preservation of the tidal waters of New York Harbor, its adiacent or tributary waters, and the waters of Long Island Sound are administered by the Supervisor of New York Harbor. The Supervisor is charged under the laws with the duties of preventing obstructive or injurious deposits in the waters under his jurisdiction and the prevention of anchorage in the entrance channels of the harbor to promote the safe navigation of deep draft vessels. The laws relating to the supervision of New York Harbor are the Act of Congress approved June 29, 1888 (25 Stat. 209) as amended by section 3 of the River and Harbor Act of August 18, 1894 (28 Stat. 360), section 8 of the River and Harbor Act of May 28, 1908 (35 Stat. 424, 426), Act of February 16, 1909 (35 Stat. 623) and Act of July 12, 1952 (66 Stat. 596); section 2 of the River and Harbor Act of August 18, 1894 (28 Stat. 360) ; and Act of Congress approved June 7, 1924 (Oil Pollution Act, 43 Stat. 604). Supervision was exercised by means of the U. S. Patrol Boats Active and San Luis II for a total of 12 boat months, two patrol launches for a total of 3 boat months, and 45 man months of shore patrol and inspection. Patrols, to the extent of available funds, were maintained to preclude obstructive or injurious material being deposited at places other than in the designated dumping grounds; to endeavor to keep the main entrance channels free of anchored craft for safe navigation by deep-draft vessels; and to detect the discharge into navigable waters of waste oil and sludge, rubbish, and other types of debris. RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 189 The total cost of all work during the fiscal year, including the cost of operating the vessels and the work of the office for the supervision of New York Harbor to 30 June 1957 was $259,000.

The Staten Island Rapid Transit Railway Company bridge crosses the Arthur Kill, New York and New Jersey Chan- nels approximately 1.5 miles south of Newark Bay and connects Elizabeth, N. J., with Staten Island, N. Y. (See U. S. Coast and Geodetic Survey Chart No. 369). Existing project. This provides for the construction of a new railroad bridge to replace the single track swing bridge completed in 1888. The center pier and fender system of the existing bridge result in inadequate horizontal clearances which present a serious obstruction and hazard to navigation. The new bridge will provide a vertical lift span with vertical clearances of 135 feet above mean high water in the open position and 31 feet above mean high water in the closed position. The new bridge will eliminate the existing center pier and leave a clear and unob- structed channel 500 feet wide. The center of the new span is to be located about 158 feet east of the center of the existing bridge. The notice to alter the existing bridge was signed by the Secre- tary of the Army on July 5, 1949, as authorized by the Truman- Hobbs Act of June 13, 1940, as amended. The estimated Federal share of the cost of new work, revised in 1956, is $8,160,000. The estimated cost to local interests, re- vised in 1956, is $1,670,000. ALTERATION OF BRIDGES-NEW YORK, N. Y., DISTRICT 221 Local cooperation. The Truman-Hobbs Act of June 23, 1940, provides that, upon notice to alter by the Secretary of War, the bridge owners shall (a) prepare and submit to the Secretary for approval, plans and specifications for the alteration of the bridge; (b) take bids for the alteration of the bridge in accordance with the approved plans; submit all bids to the Secretary together with a recommendation as to the most competent bid; submit a written guaranty that the total cost of the project will not exceed a stated sum; and upon authorization by the Secretary, proceed with the work of alteration; (c) bear such part of the cost as determined by the Secretary to be attributable to the direct and special benefits which will accrue to the bridge owners as a result of the alteration, including the expectable savings in repair or maintenance costs; and that part of the cost attributable to the requirements of traffic by railroad or highway, or both, including any expenditure for increased carrying capacity of the bridge, and including such proportion of the actual capital cost of the old bridge or of such part of the old bridge as may be altered or changed or rebuilt, as the used service life of the whole or a part, as the case may be, bears to the total estimated service life of the whole or such part. In complying with the provision of the Truman-Hobbs Act, the bridge owners have completed the following actions: (a) re- tained consulting engineers, completed necessary foundation in- vestigations, and prepared plans and specifications for the altera- tion of the bridge which have been approved by the Secretary of the Army; (b) taken bids for the construction of the substructure and approaches in accordance with the approved plans and speci- fications; submitted all bids to the Secretary together with a recommendation as to the most competent bid; submitted a written guaranty that the total cost of the project will not exceed a stated sum; and, upon authorization by the Secretary, have awarded a contract for the construction of the substructure and approaches; (c) accepted an apportionment of cost prepared by the Chief of Engineers and approved by the Secretary of the Army; (d) agreed to proceed with reconstruction of the bridge on an annual appropriation basis; and (e) donated the land re- quired for the necessary widening of the bend in the Arthur Kill at the railway bridge. Operations and results during fiscal year. Construction was continued on Contract No. 1 for the substructure and approaches, by the completion of excavation and concreting of the eleven land piers and the abutment on the New Jersey side of the project, and the abutment on the New York side; and initiating work prepara- tory to concreting on the two water piers. Contract No. 2 'for construction of the bridge superstructure was awarded, and work preliminary to construction was initiated on December 3, 1956. The total Federal cost of the work for the fiscal year was $1,170,825, all for new work. 222 REPORT OF THE CHIEF OF' ENGINEERS, U. S. ARMY, 1957 Condition at end of fiscal year. The overall project was about 16 percent completed on June 30, 1957. Contract No. 1 for the substructure was about 69 percent completed, and Contract No. 2 for the superstructure was less than 1 percent completed. The work remaining to be done consists of completion of the substruc- ture and superstructure of the new bridge and removal of the old bridge. The total Federal cost of the existing project to June 30, 1957, was $1,266,767, all for new work.

This inlet is located on the east coast of New Jersey, about 50 miles south of Sandy Hook. It forms the main entrance to Barnegat Bay, the largest of the bays on the New Jersey coast which are separated from the ocean by narrow barrier beaches. The inlet lies between Island Beach on the north and Long Beach on the south. (See U. S. Coast and Geodetic Survey Charts Nos. 825 and 1216.) Existing project. This provides for a channel 8 feet deep through the inlet and 10 feet through the outer bar, the channel to be protected by two converging stone jetties extending to the 12-foot contour in the ocean and spaced 1,000 feet apart at the outer ends; a channel of suitable hydraulic characteristics ex- tending in a northwesterly direction from the gorge in the inlet to Oyster Creek Channel just northwest of Sunset Shoal, thence via Oyster Creek Channel to deep water in the bay; and the maintenance of a channel 8 feet deep and 200 feet wide to connect Barnegat City Harbor with the main inlet channel. The total length of the section included in the project is about 4.5 miles. All depths refer to the plane of mean low water. The mean tidal range at the inlet gorge is 2.7 feet and in Barnegat Bay 0.5 foot. The extreme tidal range at the inlet is from about 2 feet below mean low water to about 3 feet above mean high water. The cost for new work for the completed project was $448,849, exclusive of $300,000 contributed by local interests. The average annual maintenance cost during the past 5 years was $68,431.

Assurances of local cooperation furnished by local interests in connection with the deepening of the channel only, were approved by the Chief of Engineers on February 15, 1951. The requirements under prior acts have been fully complied with. RIVERS AND HARBORS-PHILADELPHIA, PA., DISTRICT 257 Terminal facilities. Five landings with a total wharfage of 700 feet, used by commercial fishermen, and 7 landings and boat basins for pleasure craft are located along the river and its branches. The pleasure boat landings and basins are equipped with marine railways, boatbuilding and repair facilities, and boat storage facilities. Two yacht clubs with a mooring capacity of 45 boats and numerous pleasure boat landings are also located along the waterway. The existing facilities are considered adequate for present requirements. Operations and results during fiscal year. Maintenance, con- tract: Rehabilitation of the south bulkhead was commenced April 30, 1957 and was completed May 17, 1957. Costs were $965. Maintenance, hired labor: An examination of the channel and structures was made at a cost of $1,786. The cost of all work was $2,751 for maintenance. Condition at end of fiscal year. The existing project was about 82 percent complete. Two rubblemound jetties, 1,230 feet long north of the entrance and 1,030 feet long south of the entrance, were completed in 1931. Two steel bulkheads, each 950 feet long, at the inshore ends of the jetties, were completed in 1937. A steel bulkhead 698 feet long and two steel groins of an aggregate length of 570 feet, constructed on the northerly beach, were completed in 1938. A channel 10 feet deep and 250 feet wide from the 10-foot depth curve in the ocean to a point near the inshore ends of the jetties and thence 8 feet deep and 300 feet wide to a point 700 feet below the New York and Long Branch Railroad was completed in 1933, and the widening on the northerly side of the channel was completed in 1938. The work remaining to be done is the deepening of the channel between the jetties from 10 feet to 14 feet, thence to a point 700 feet below the railroad bridge from 8 feet to 12 feet, and extending the 12-foot channel to within 300 feet of the railroad bridge; also the dredging of the 19-acre anchorage south of the channel and 27.5-acre anchorage west of the highway bridge.

NEW JERSEY INTRACOASTAL WATERWAY Location. This waterway, a sea-level inland water route approximately parallel with the New Jersey coast, extends from the Atlantic Ocean at Manasquan Inlet, about 26 miles south of Sandy Hook, N. J., to Delaware Bay about 3 miles above Cape May Point. The waterway extends through the inlet and up Manasquan River a distance of about 2 miles; thence by the Manasquan-Bayhead Canal through high ground for a distance of 2 miles to the head of Barnegat Bay. It then passes through a series of bays, lagoons, and thoroughfares along the New Jersey coast to Cape May Harbor; thence across Cape May County to Delaware Bay through a land cut by way of the New England Creek basin. (See U. S. Coast and Geodetic Survey Charts Nos. 234, 795, 825, 826, 827, 1216, 1217, 1218, and 1219.) Existing project. This provides for a channel 12 feet deep at mean low water and generally 100 feet wide, extending from the Atlantic Ocean at Manasquan Inlet, N. J., to Delaware Bay above Cape May, N. J., by the further improvement of Manasquan River and Inlet, N. J., and the present New Jersey Intracoastal Waterway, and by the construction of a canal of similar dimen- sions from Cape May Harbor to Delaware Bay via the New England Creek basin, with adequate jetties at the Delaware Bay entrance. The total length of the project is about 117 miles. Normal tidal range in sections of the waterway remote from inlets is 0.5 foot. Near the inlets the mean tidal range generally is 3 feet; in the ocean, 4 feet; at the head of Cape May Harbor, 4.6 feet; and in Delaware Bay, near the entrance, 4.7 feet. The estimate of cost for new work is $54,000 (July 1954), exclusive of $1,824,940 Navy Department funds and $99,000 contributed by local interests. The average annual maintenance cost during the past 5 years was $133,825. The portion of the project extending from Manasquan River to Cape May Harbor is to be restudied and is excluded from the new work cost estimate. The estimated cost of this portion is $6,470,000 (July 1954). The existing project was adopted by the River and Harbor Act approved March 2, 1945 (H. Doc. 133, 76th Cong., 1st sess.). The latest published map is in the project document. The River and Harbor Act approved July 24, 1946 (Public Law 525, 79th Cong., 2d sess., as extended by Public Law No. 240, 82d Cong., dated October 30, 1951), authorized the use for a period not to exceed 6 years, of funds from appropriations heretofore or hereafter made for maintenance and improvement of rivers and harbors, for the maintenance of the canal from Cape May Harbor to Delaware Bay constructed as an emergency wartime project with Navy Department funds, including the cost of maintaining the temporary railroad and seashore highway bridges over the canal. RIVERS AND HARBORS-PHILADELPHIA, PA., DISTRICT 259 Local cooperation. The project is subject to the conditions that the State of New Jersey cede to the United States all right, title, and interest that it has acquired to lands, easements, rights-of- way, and structures other than bridges for the Manasquan- Bayhead Canal; that the State of New Jersey furnish, free of cost to the United States, all lands, easements, rights-of-way, and disposal areas required for construction of the Cape May Canal and for improvement of the proposed waterway and for their subsequent maintenance; that local interests provide, maintain, and operate suitable bridges over the waterway; that the State of New Jersey donate to the United States the navigation aids in use on the present New Jersey Intracoastal Waterway; and that the State of New Jersey hold and save the United States and its agents free from any claims for damages resulting from the work of improvement. Compliance with these conditions was completed January 15, 1954, except that local interests are required to furnish disposal areas for the construction and the subsequent maintenance of the proposed improvement. Terminal facilities. There are numerous piers, wharves, and docks at resorts located at or adjacent to the waterway, most of which are open to general public use, and fuel, water, and other supplies are readily available. Public and privately owned boat basins are located in a number of streams entering the bays and thoroughfares through which the waterway passes. Boat repair and storage yards with marine railways for small craft are also scattered along the waterway. Transfer facilities, including facilities for icing, storing, and shipping food fish, are available at most of the larger communities along the waterway, including Atlantic City, Wildwood, and Cape May. The plants at the two latter places have direct railroad connections. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance, con- tract: Dredging miscellaneous shoals by leased dredge com- menced January 14, 1957 and was completed on May 20, 1957. A total of about 520,000 cubic yards of material, place measure- ment, was removed at a cost of $391,039. Costs in the amount of - $338 were incurred in connection with a contract for fencing Bayhead-Manasquan Canal completed in the previous fiscal year. Maintenance, hired labor: Costs in the amount of $890 were incurred for removal of unused wharf and office in Cape May Canal, $486 for disposals of leased and Government owned real estate; removal of a small shoal, $2,664 and $5,676 for real estate management services. The cost of all work was $400,417 for maintenance. Condition at end of fiscal year. The existing project was about 25 percent complete. A canal 12 feet deep and 100 feet wide from Cape May Harbor to Delaware Bay was completed in 1942; two parallel stone jetties at the Delaware Bay entrance and a temporary highway drawbridge in 1943; and a temporary high- way drawbridge and a railroad bridge in 1944, all with Navy Department funds. The work remaining to be done is the dredging of a channel 12 feet deep and 100 feet wide from the Atlantic Ocean at Manasquan Inlet to Cape May Harbor. 260 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The inactive portion is widening the 35-foot depth channel from 150 feet to 400 feet from Port Covington to Ferry Bar, widening the 27-foot depth channel from 150 feet to 250 feet to Hanover Street bridge, and providing a channel 27 feet deep by 250 feet wide to the Western Maryland Railway bridge with an anchorage and turning basin at the upper end. 276 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 nel from 150 feet to 250 feet to Hanover Street Bridge, and provid- ing a channel 27 feet deep by 250 feet wide to the Western Mary- land Railway bridge with an anchorage and turning basin at the upper end is considered to be an inactive portion of the project and is excluded from the foregoing estimate. The cost of this portion was last revised in 1954, and was estimated to be $1,603,000. Local cooperation. The River and Harbor Act of August 8, 1917, required that on all new work under the project approved by that act, except the channel into Curtis Bay, improvement by the United States is conditional upon local interests providing, free of cost to the United States, suitable disposal areas behind bulkheads or other revetment, satisfactory to the district engineer, whenever required by the Chief of Engineers. This condition has been met as far as the channel has been completed. The River and Harbor Act of July 3, 1930, provided for in- creased anchorage facilities subject to the provisions that no work shall be started on the area therein recommended until local in- terests have provided suitable disposal areas satisfactory to the district engineer alongside of bulkheads behind which said in- terests will agree to pump the material without delay to the Government work; or. in lieu of the above requirement, agree to contribute the sum of 5 cents per cubic yard, scow measure, to cover the additional cost to the United States for disposal of the material on its own dumping area. This condition has been met. The River and Harbor Act of March 2, 1945, required that re- sponsible local interests agree to hold and save the United States free from claims for damage resulting from the work. This condi- tion has been met in a resolution adopted by the city council of Baltimore and approved by the mayor on March 1, 1949. Terminal facilities. The Port of Baltimore consists of 46 miles of waterfront, 30 miles of which are developed. There are 271 piers, wharves, and docks in Baltimore Harbor with depths in the berthing areas ranging up to 40 feet at mean low water. Most deep- draft shipping, other than that handled at the wharves of the nu- merous industrial plants, is concentrated at the modern ocean ter- minals operated by three trunkline railroads, the Baltimore & Ohio, the Pennsylvania, and the Western Maryland; and by a terminal railroad, the Canton. All of these terminals are equipped with depressed or apron tracks permitting the transfer of cargoes directly between ship and car. Facilities also are provided at the rail terminals for the receipt and delivery of motor truck freight. The railroads, with tracks extending to all portions of the port area, have voluntarily granted 5 days free time on piers to truck freight on both imports and exports. The supporting yards for the railroad terminals can accommodate a total of 11,800 cars and the combined ground storage capacity is 32,250 cars. Major facilities in the port include 3 grain elevators with a total capacity of approximately 12 million bushels, 15 modern ore cranes with a total rated unloading capacity of more than 11,000 tons per hour, 30 public general-merchandise warehouses, 3 modern cold-storage RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 277 facilities, 4 coal piers, 13 oil receiving stations and 2 refining plants, and 12 shipbuilding and ship repair yards. The shipbuild- ing and repair yards are equipped with facilities for handling every type of vessel construction, conversion, and repair. The facil- ities include 11 shipways ranging in length from 150 to 650 feet, 7 floating drydocks with lifting capacities of from 6,000 tons to 20,000 tons, 2 graving docks and 7 marine railways in addition to numerous outfitting piers and shops. All piers are accessible by adequate paved highways. A municipally owned beltline railway some 3 miles long encircles the upper end of the inner harbor and connects the tracks of the Baltimore & Ohio, Pennsylvania, and Western Maryland Railroads. The latest description of terminal facilities is contained in the publication entitled "Port Series No. 10 (Revised 1946)" on the Port of Baltimore, Md., issued by the Board of Engineers for Rivers and Harbors. The State legislature has authorized the city of Baltimore to in- cur an indebtedness of $60 million for further development of port facilities. The Port of Baltimore Commission, which is charged with administration under this authorization, is reviewing re- quests from various companies who desire to obtain funds for con- struction and reconstruction of port facilities. The Commission is presently processing applications for loans totaling more than $41 million. The Commission expects work utilizing most of these funds to begin in the near future. Under authorization granted by the former Port Development Commission, the following work was completed: An $8,500,000 terminal pier at Port Covington, and a $1,500,000 terminal pier on the Canton area of the port. The Port of Baltimore Commission, with more liberal financing powers, re- placed the Port Development Commission. The City of Baltimore expends about $100,000 annually for rehabilitation of existing structures. Operations and results during fiscal year. Maintenance dredg- ing, by the U. S. hopper dredge Chester Harding, to restore proj- ect dimensions in the Craighill-Cutoff Angle, Cutoff-Brewerton Angle and the Northwest Branch commenced April 16, 1957 and was completed June 30, 1957. A total of 850,000 cubic yards, place measure, of material was removed and deposited on the authorized dumping area in Chesapeake Bay at Kent Island, Md. Condition surveys and estimates of yardage of shoal material were made by hired labor in reaches of the main channel and in the Kent Island disposal area. The total costs, all for maintenance, were $234,073. Condition at end of fiscal year. The active portion of the exist- ing project, excluding the York Spit Channel which is under the jurisdiction of the Norfolk District, was completed in March 1954. The total costs under the existing project (including York Spit Channel prior to fiscal year 1942) were $15,802,768 of which $8,329,403 was for new work and $7,473,365 was for maintenance.

BALTIMORE HARBOR, MD., COLLECTION AND REMOVAL OF DRIFT Location. The project applies to Baltimore Harbor, Md., and its tributaries. Existing project. This provides for the collection and removal of drift from Baltimore Harbor and its tributary waters, and authorizes the Secretary of the Army to allot such amounts as may be necessary for the work from appropriations for maintenance and improvement of existing river and harbor works or other available appropriations, and that this work shall be carried as a separate and distinct project. It is wholly a work of maintenance. The purpose of the work is to afford relief from variable conditions of obstruction. RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 279 The average annual maintenance cost during the past 5 years was $39,200. The existing project was authorized by the River and Harbor Act of June 30, 1948. Terminal facilities. Described in the report for Baltimore Harbor and Channels, Md. Operationsand results during fiscal year. Operations, by hired labor, consisted of the collection and disposal of 45,125 cubic feet of driftwood, ranging from small blocks up to timbers of large dimensions. The total costs, all for maintenance were $41,424. Condition at end of fiscal year. The existing project is one of continuous maintenance for which no percentage of completion exists. Navigation has been made safer by continual patrol of the harbor and removal of drift material which began in July 1949. The total costs, all for maintenance for removing and disposing of 393,972 cubic feet of driftwood were $342,681.

ROCK HALL HARBOR, MD. Location. Rock Hall Harbor is a shallow, open cove on the east side of Chesapeake Bay immediately to the south of Swan Point and 23 miles southeast of Baltimore. (See U. S. Coast and Geodetic Survey Charts No. 548 and 1226.) Previousprojects. The original project was dated June 3, 1896. Modifications were made by the River and Harbor Acts of June 13, 1902, and March 4, 1913. For further details, see page 493 of the Annual Report for 1920, and page 370 of the Annual Report for 1938. Existing project. Provides for a channel 10 feet deep and 100 feet wide from the 10-foot depth curve in Swan Creek Inlet to a channel of the same dimensions, 700 feet in length parallel to the harbor terminals at Rock Hall; an anchorage basin of the same depth 100 feet wide, 250 feet long in a northwesterly extension of the channel fronting the harbor terminals; an anchorage basin 8 feet deep, 100 feet wide and 350 feet long on an extension of the centerline of the 10-foot basin; with an anchorage basin 8 feet deep, 200 feet wide, and 600 feet long attached to and extending in a southwesterly direction from the west end of the above mentioned 8-foot basin; with twin breakwaters at the harbor entrance. The cost of new work for the completed project was $113,903, exclusive of amounts expended on previous projects. The existing project was adopted by the River and Harbor Act of August 26, 280 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 1937 (H. Doc. 204, 75th Cong., 1st sess.), and modified by the River and Harbor Act of June 30, 1948 (H. Dec. 273, 80th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Local interests have constructed a btilkhead 500 feet long and have acquired and reserved for public use an area 100 feet wide behind the bulkhead with a highway connection thereto. It is required that they furnish free of cost to the United States, when and as required, all lands, easements, rights-of-way, and spoil-disposal areas for new work and subsequent main- tenance; and hold and save the United States free from damages due to the improvements. Assurances of local cooperation were approved on December 21, 1955. Terminal facilities. There are several private terminals, a marine railway, a public timber-pile wharf, and a public bulkhead wharf about 500 feet long. Present facilities are adequate for existing and reasonably prospective commerce. Operations and results during fiscal year.

QUEENSTOWN HARBOR, MD. Location. Queenstown Creek is an estuary of Chester River about 2 miles long on the easterly side of the Chesapeake Bay about RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 281 35 miles southeast of Baltimore. (See U. S. Coast and Geodetic Survey Chart No. 548.) Previous projects. The original project was dated March 3, 1871. The cost and expenditures on it prior to adoption of the existing project in 1902 were $19,000. For further details of previous projects see page 1789 of Annual Report for 1915. Existing project. This provides for a channel 10 feet deep at mean low water and 200 feet wide from that depth in Chester River to the 10-foot contour in Queenstown Creek, a distance of about 4,000 feet; and for a channel 7 feet deep at mean low water and 75 feet wide extending from the 7-foot contour in Queenstown Creek to and including a mooring basin of the same depth and 300 feet square opposite the town wharf in Little Queenstown Creek. The mean range of tide is about 1.3 feet; however, greater fluctuations frequently result from prolonged or high winds. The estimate of cost of new work, revised in 1957, is $54,000. The existing project was adopted by the River and Harbor Acts of June 13, 1902 (H. Doc. 92, 56th Cong., 1st sess.) and September 3, 1954 (H. Doc. 718, 81st Cong., 2d sess.). Maps are published in the project documents. Local cooperation. None required for the 10-foot depth and 200-foot width portion of the project, authorized by the River and Harbor Act of June 13, 1902. Under the remaining portion of the project, authorized by the River and Harbor Act of September 3, 1954, local interests are to furnish without cost to the United States all lands, easements, rights-of-way, and suitable spoil-disposal areas for initial work and for subsequent maintenance when and as required; and hold and save the United States free from damages due to construction and maintenance of the project, including such damage as may occur to the public or leased oyster beds. Assurances of local cooperation were approved on March 29, 1956. Terminal facilities. There are several small private wharves and bulkheads on Little Queenstown Creek. A public bulkhead wharf has been constructed and dredging to a depth of 7 feet of the area around the wharf has been accomplished by order of the town commissioners of Queenstown, Md. Local interests are plan- ning to install gasoline tanks on the town wharf in the near future. Adequate space is available for the construction of additional private or public wharves. Operations and results during fiscal year. New work dredging, by contract, to provide a channel 7 feet deep, and 75 feet wide extending from the 7-foot contour in Queenstown Creek to and including a mooring basin of the same depth and 300 feet square opposite the town wharf in Little Queenstown Creek began June 10, 1957 and was continued throughout the fiscal year. A total of 13,300 cubic yards of material, place measure, was removed and deposited in authorized spoil-disposal areas ashore. The total costs, all for new work were $12,140.

Location. Black Walnut Harbor is a large tidal cove on the east side of Chesapeake Bay at the south end of Tilghman Island near the entrance to the Choptank River, and is about 50 miles south of Baltimore, Md. It is about 4,500 feet long. (See U. S. Coast and Geodetic Survey Chart No. 1225.) Existing project. This provides for a channel 6 feet deep and 60 feet wide to and including an anchorage basin of the same depth 400 feet square. The mean range of tide is about 1.4 feet. Greater fluctuations are caused by prolonged high winds on Chesa- peake Bay. The harbor is well sheltered except from the south. The cost of new work for the completed project was $32,631. The average annual maintenance cost for the past 5 years was $6,600. The existing project was adopted by the River and Harbor Act of March 2, 1945 (House Doc. 217, 76th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Fully complied with except that local in- terests are to furnish spoil-disposal areas as needed for future maintenance. Terminal facilities. There are a few small timber wharves at Fairbank, one of which is publicly owned. Similar facilities exist at Bar Neck. There is also a small marine railway and boat-repair yard on Barney Cove, the western prong of the harbor. Sufficient areas are available for the erection of additional terminals if required. Operations and results during fiscal year. Maintenance dredg- ing, by contract, to restore project dimensions in the channel and anchorage basin began March 19, 1957 and was completed June 28, 1957.

NANTICOKE RIVER (INCLUDING NORTHWEST FORK), DEL. AND MD. Location. The headwaters of Nanticoke River consist of numerous branches rising mainly in the northern portion of Sussex County, Del. The river is about 50 miles long and flows in a south- westerly direction from its source to Tangier Sound. The Northwest Fork is a branch of the Nanticoke River which rises in Kent County, Del., and flows past Federalsburg, Md., in a generally southerly direction through Dorchester County, Md., to its junction with the main river opposite Riverton, Md. It is about 30 miles in length. (See U. S. Coast and Geodetic Survey Chart No. 77.) Previous projects. The original project for the Nanticoke River was adopted August 18, 1894. For further details, see page 1790 of Annual Report for 1915, and page 378 of Annual Report for 1938. There has been no previous project for Northwest Fork. Existing project. Nanticoke River: This provides for a channel 12 feet deep and 100 feet wide from the 12-foot contour in Tangier Sound to the highway bridge at Seaford, Del., with a turning basin at the upper end. The length of the disjointed sections included in the project is about 4 miles, extending over 32 miles of the river; the lower end of the first section of the project is about 8 miles above the mouth of the river. The mean range of tide is 3.4 feet and the extreme tidal range is 4.3 feet. Northwest Fork: This provides for dredging a channel 6 feet deep and 60 feet wide at mean low water from upper Browns wharf to within one-half mile of the southern boundary of the town of Federalsburg, with a turning basin at the upper end. The length of the section included in the project is about 4 miles, and its lower end is 113/4 miles above the mouth of the river. The mean range of tide is 2.6 feet, and the extreme tidal range is 3.3 feet. The cost of new work for the completed project was $138,134, exclusive of amounts expended on previous projects. 284 REPORT OF THE CHIEF OF ENGINEERS, U. S.

Local cooperation. Local interests are required to furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas necessary for the improvement and for subsequent maintenance, when and as required, and hold and save the United States free from claims for damages resulting from the improvement. Assurances of local cooperation were approved on February 21, 1956. Terminal facilities. The waterfront at Seaford consists largely of unconnected pile-and-timber bulkhead wharves with earthfills. One public wharf is used principally for unloading fuel oil for the local utility plant. The remaining wharves are privately owned. A rail siding extends along a considerable portion of the waterfront and offers facilities for interchange of rail and water traffic. Exist- ing terminals are reasonably adequate for present and prospective commerce. The terminal facilities on the Northwest Fork are all privately owned and open to general public use. They consist of 1 solid bulk- head wharf of 80-foot frontage and 3 landings each with 60-foot frontage. The depths of water are from 2 to 8 feet. The landings are log revetments backed by earthfill and are in poor condition. Operations and results during fiscal year. New work dredging, by contract, to provide a channel 12 feet deep, at mean low water, and 100 feet wide from the 12-foot contour in Tangier Sound to the highway bridge at Seaford, Del., was continued and completed July 20, 1956. A total of 49,677 cubic yards of material, place measure, was removed and deposited ashore in authorized spoil- disposal areas. The total costs, all for new work, were $30,380.

The total costs of the existing project were $176,817, of which $138,134 was for new work and $38,683 was for maintenance. 7. WICOMICO RIVER, MD. Location. Wicomico River has its source in the northern part of Wicomico County, Md., and flows in a generally southwardly direction, emptying into Monie Bay, a tributary of Tangier Sound on the east side of Chesapeake Bay about 85 miles southeast of Baltimore. Webster Cove is the site of an improved small-boat harbor located on the southeast bank of the Wicomico River about 3 miles above the mouth. (See U. S. Coast and Geodetic Survey Charts Nos. 567 and 1224.) Previous projects. Adopted by River and Harbor Act of June 10, 1872. For further details see page 1789 of Annual Report for 1915, and page 380 of Annual Report for 1938. Existing project. This provides for a channel 14 feet deep and 150 feet wide from Chesapeake Bay to Salisbury, the length of the section included in the project being 37 miles, including about 12 miles from the mouth of the river to Chesapeake Bay; a depth of 14 feet in the channels and turning basins in the north and south prongs with channel widths of 100 feet, and a channel 6 feet deep and 60 feet wide extending from the 6-foot contour in Wicomico River to and including a basin in Webster Cove of the same depth, 100 feet wide and 400 feet long; and extension of the basin 200 feet long and 100 feet wide on each side. The plane of reference is mean low water. Mean range of tide is about 3 feet and the extreme tidal range is 4.4 feet. The Federal cost of new work for the completed project was $421,609, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $3,600. The existing project was authorized by the following: Acts Work authorized Documents Sept. 19, 1890 Channel 9 feet deep from Main St. Bridge to about H.

S. ARMY, 1957 Local cooperation. Fully complied with for work authorized under the River and Harbor Act approved August 26, 1937, and prior acts, except that local interests are to furnish spoil-disposal areas as required for future maintenance. Work authorized under the River and Harbor Act approved Sep- tember 3, 1954, requires that local interests agree to: (1) provide without cost to the United States all lands, easements, and rights- of-way necessary for construction and maintenance of the im- provement and furnish suitable spoil-disposal areas for initial work and subsequent maintenance when and as required; (2) acquire and reserve for public use a strip of land at least 50 feet wide on the southeast side abutting the Federal right-of-way re- quired for the extension of the basin in Webster Cove and a 10- foot right-of-way on all other sides of the extension and on the northeast side of the existing basin to guarantee free public access; and (3) hold and save the United States free from all damages due to construction and maintenance of the project, including such damage as may occur to public or leased oyster beds. Assurances of local cooperation were approved on July 19, 1956. Terminal facilities. The present water front at Salisbury con- sists of pile-and-timber bulkheads with earthfills. Some of the wharves have warehouses and factories with mechanical freight- handling facilities and rail sidings. With the exception of a wharf on the north prong, owned by the State Roads Commission, and a wharf on the south prong, owned by the county, all of the terminals are privately owned. A shipyard, with 2 marine rail- ways with capacities of 1,200 and 500 tons, respectively, is located on the right bank of the river below the prongs. Areas for the development of new terminals on the north and south prongs are limited. Areas for a considerable expansion of terminal facilities are available on the main river. A public wharf on the main river at Salisbury is desirable but not essential. There is a pile-and-timber wharf which is situated about 4 miles above the mouth of the river at Mount Vernon. There is a wharf of similar construction at White Haven. There is a county wharf at the head of the basin in Webster Cove, a pile-and-timber pier at the oyster house on the southwest side of the basin, a T-shaped pile-and-timber pier at the cafe on the southwest side of the basin and several small timber piers or walkways that have been constructed around the basin by local interests. Fueling facilities are available at the T-shaped pier. Sufficient areas are available for the construction of additional facilities when required. Operations and results during fiscal year. New work by con- tract, to provide for enlarging the existing basin at Webster Cove, by dredging an extension 6 feet deep, 100 feet wide and 200 feet long on each side of the existing basin to form a T-shaped harbor began October 2, 1956 and was completed November 3, 1956. A total of 21,100 cubic yards of material was removed and deposited ashore in authorized spoil-disposal areas. The total costs, all for new work, were $13,762. RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 287 Condition at end of fiscal year. The existing project was com- pleted in 1942 except for enlarging the basin in Webster Cove which was completed November 3, 1956.

CRISFIELD HARBOR, MD. Location. The harbor is situated along the western limits of the town of Crisfield on the east bank of Little Annemessex River, an estuary of Tangier Sound on the east side of Chesapeake Bay. (See U. S. Coast and Geodetic Survey Chart No. 1224.) Previous projects. The original project was adopted by the River and Harbor Act approved March 3, 1875, and modified by the River and Harbor Act approved March 2, 1907. For further details see page 1790 of Annual Report for 1915, page 432 of Annual Report for 1924, and page 384 of Annual Report for 1938. Existing project. This provides for a channel 12 feet deep at mean low water, 425 feet wide from the 12-foot contour in Tangier Sound to Somers Cove Light, thence 266 feet wide to the bend about 1,800 feet southwest of the railroad pier, and thence of irregular width to a point opposite the Consumers Ice Co.; a spur channel 10 feet deep and 100 feet wide from the ice plant to Hop Point; a channel 7 feet deep and 60 feet wide from the 7-foot depth curve in Little Annemessex River, via Cedar Creek, a land- cut, and Daugherty Creek to Big Annemessex River; a mooring basin 7 feet deep, 160 feet wide and approximately 875 feet long roughly parallel to Brick Kiln Road, with a channel 7 feet deep and 100 feet wide leading therefrom to the 7-foot project channel con- necting Little Annemessex and Big Annemessex Rivers; and for an anchorage basin in Somers Cove 10 feet deep, 600 feet wide, and 1,000 feet long, with an approach channel 10 feet deep and 100 feet wide from the 10-foot depth curve in Little Annemessex River through a land cut in Jersey Island to the basin in Somers Cove. 288 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The mean range of tide at Crisfield is about 1.9 feet and the extreme range is about 6 feet. The estimated Federal cost of new work, revised in 1957, is $279,000 exclusive of amounts expended under previous projects. The average annual maintenance cost during the past 5 years was $3,250. The existing project was authorized by the following: Acts Work authorized Documents 1 Mar. 3, 1925 A 12-foot channel of varying widths to opposite the H. Doc. 355, 68th Cong., 1st sess.

Local cooperation. Fully complied with for improvements authorized under the River and Harbor Act of March 2, 1945, and prior acts except that local interests are to furnish spoil-disposal areas as required for future maintenance. The River and Harbor Act approved September 3, 1954, modi- fied the project to provide for an anchorage basin in Somers Cove and approach channel thereto subject to the conditions that local interests are required to furnish free of cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas for the construction and maintenance of the project when and as required; remove existing structures from the area to be dredged; hold and save the United States free from damages due to the construction and maintenance of the project; construct a suitable road con- necting the lower portion of Jersey Island with Crisfield; and to contribute a sum equal to the estimated difference in cost between providing an entrance channel through the present entrance to Somers Cove and providing the channel across Jersey Island. Local interests have expressed unwillingness to comply with the terms of local cooperation and have requested a departure from the plan contained in the authorizing document. Such modification would provide for entrance to Somers Cove via the existing open- ing to the Cove rather than by land cut across Jersey Island. It is believed that local interests will meet the requirements of local cooperation if the requested modification is approved. Terminal facilities. The waterfront of Crisfield Harbor is built up principally with solid-bulkhead wharves and pile-and-timber piers. The majority of the wharves are privately owned, but are RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 289 open to the public for transaction of business with the owners. A few of the terminals have mechanical freight-handling devices, but most of the freight is transferred by hand. There are 3 boat-repair yards with marine railways having capacities up to 250 tons. The existing terminals are adequate for present and reasonably pro- spective commerce. Sufficient areas are available north of Hop Point and on Somers Cove for the construction of additional terminals as needed. Operations and results during fiscal year. Operations consisted of negotiations with local interests in connection with preconstruc- tion planning for providing an anchorage basin in Somers Cove and an approach channel thereto. The total costs, all for new work, were $328. Condition at end of fiscal year. The project was completed in March 1948 except for providing an anchorage basin in Somers Cove and an approach channel thereto. The controlling depths, at mean low water, were 11.3 feet in midchannel from Tangier Sound to Consumers Ice Company Wharf, ascertained in November 1954; 4.4 feet in midchannel from the ice plant to Hop Point, ascertained in August 1954; and 7 feet from Little Annemessex River to Big Annemessex River via Cedar and Daugherty Creeks and 7 feet in the mooring basin adjacent to Brick Kiln Road, ascertained in March 1946. The condition of the basin in Somers Cove is as described in the project document. The work remaining to be done is providing an anchorage basin in Somers Cove and an approach channel thereto, authorized by the River and Harbor Act of September 3, 1954. The total costs under the existing project were $195,888, of which $176,783 was for new work and $19,105 was for maintenance.

POCOMOKE RIVER, MD. Location. This river is a tributary of Pocomoke Sound, an estuary of and on the easterly side of Chesapeake Bay about 40 miles north of Cape Charles, Va. Previous projects. The original project for Pocomoke River was adopted June 18, 1878, and modified by the River and Harbor 290 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Act of August 5, 1886. For further details, see page 1789, Annual Report for 1915, and page 385, Annual Report for 1938. Existing project. This provides for a channel 11 feet deep at mean low water and 150 feet wide from the 11-foot depth in Pocomoke Sound to Tulls Point, thence 100 feet wide to deep water in Pocomoke River above Williams Point, and for construction of a dike along the offshore side of the channel between Tulls Point and the end of the existing dike; and a channel 9 feet deep at mean low water and 100 to 130 feet wide from Shad Landing to the bridge at Snow Hill. The length of the project is about 8.7 miles from Pocomoke Sound to Williams Point, and about 4.5 miles from Shad Landing to Snow Hill, Md. Shad Landing is about 25.7 miles above the mouth of the river. The mean range of tide is 2.4 feet in Pocomoke Sound and 2.5 feet in the river at Snow Hill. Prolonged high winds on Chesa- peake Bay frequently cause greater fluctuations. The estimated Federal cost of new work, revised in 1957 is $841,000, exclusive of amounts expended under previous projects. The average annual maintenance cost during the past 5 years was $31,400. Extension of the channel above the bridge at Snow Hill, 100 feet wide, 9 feet deep and widened to 150 feet to form a turning basin at the upper end, is considered to be an inactive portion of the project and is excluded from the foregoing estimate. The cost of this portion was last revised in 1956 and was estimated to be $22,000. The existing project was authorized by the following: Acts Work authorized Documents June 3, 1896 A 9-foot channel from Shad Landing to Snow Hill___ Annual report for 1895, p. 1167. 1 Aug. 30, 1935 For a channel 7 feet deep and 100 feet wide from H.

Local cooperation. Fully complied with for the section of the project from Pocomoke Sound to Pocomoke River and from Shad Landing to the highway bridge at Snow Hill, authorized by the acts of June 3, 1896, and August 30, 1935, except that local in- terests are required to furnish releases from damage to oyster beds and spoil-disposal areas as required for future maintenance. The terms of local cooperation for the section of the project above the highway bridge at Snow Hill, authorized by the Act of March 2, 1945, require that local interests furnish, free of cost to the United States, all lands, easements, and rights-of-way and spoil-disposal areas for the initial work and for subsequent main- tenance, when and as required; hold and save the United States RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 291 free from claims for damages resulting from the improvement; and contribute one-half the initial cost of that portion of the project, but not to exceed $4,250. This portion of the project is considered to be inactive. The terms of local cooperation for the 11-foot depth channel from Pocomoke Sound to deep water in Pocomoke River above Williams Point authorized by the act of September 3, 1954, require that local interests provide without cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas necessary for the construction and subsequent maintenance of the project, when and as required; and hold and save the United States free from damages due to the construction and maintenance of the project, including such damage as may occur to public or leased oyster beds. It is believed that these conditions will be met. Terminal facilities. The waterfronts at Pocomoke City and Snow Hill are built up principally with earth-filled timber bulk- heads, the majority of which are privately owned. A few of the warehouses and factories situated on the river at these communi- ties have railroad sidings and mechanical freight-handling facili- ties. Any appreciable increase in commerce at Pocomoke City or Snow Hill would necessitate the construction of new facilities and repair of existing structures.

RIVERS AND HARBORS-BALTIMORE, MD., DISTRICT 295 12. WATERWAY ON THE COAST OF VIRGINIA Location. The waterway lies between the barrier beach along the Atlantic Ocean on the east and the Virginia portion of the mainland peninsula on the west. It extends from the south end of Chincoteague Bay through a number of creeks, thoroughfares and bays, to enter Chesapeake Bay in the vicinity of Fisherman Inlet, just south of Cape Charles, the southern tip of the peninsula, for a distance of 83.7 miles. (See U. S. Coast and Geodetic Survey Charts Nos. 1220, 1221, and 1222.) Existing project. This provides for an inland waterway 6 feet deep and 60 feet wide from Chesapeake Bay to Chincoteague Bay, Va. The mean range of tide is about 3 feet. Greater fluctuations in water level are caused by high winds and storms. The estimate of cost for new work, revised in 1957, is $1,039,000. The average annual maintenance cost for the past 5 years was $5,100. The existing project was adopted by the River and Harbor Act of June 25, 1910 (H. Doc. 957, 60th Cong., 1st sess.), and modified by the River and Harbor Act of March 2, 1945 (H. Doc. 268, 76th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Local interests are to furnish free of cost to the United States, as and when required, all lands, easements, and rights-of-way and spoil-disposal areas for the initial work and for subsequent maintenance, and hold and save the United States free from all claims for damages resulting from the work of improve- ment. These terms have been partially met by local interests. Local interests are expected to meet the terms when required, and will furnish spoil-disposal areas for subsequent maintenance. As- surances of local cooperation were approved on February 27, 1957. Terminal facilities. The larger towns in the area adiacent to the route of the desired improvement have fairly substantial pile- and-timber wharves which are used primarily by boats engaged in the seafood business. There are also a number of small landings scattered along the shore between the towns. The Pennsylvania Railroad owns and operates a water terminal at Franklin City. There are also wharves at the various Coast Guard stations in the area. All of the wharves are privately owned, but are open to the public for transaction of business with the owners. No mechanical freight-handling facilities are available. The terminals are ade- quate for existing commerce. A material increase in commerce which would follow the proposed improvement makes desirable but not essential the erection of adequate terminals at Chinco- teague, Wachapreague, Willis Wharf, and Oyster. Adequate public facilities are available at Ocean City. Operationsand results during fiscal year.

The mean range of ocean tide is 3.4 feet. The extreme range is from 3 feet below mean low water to about 3.5 feet above mean high water, a total of 9.9 feet. In the bays the mean range of tide varies from approximately 2.5 feet at the inlet to 0.3 foot at their heads. Greater fluctuations are caused by prolonged high winds. The estimate of cost for new work, revised in 1957, is $508,000 exclusive of $500,000 contributed by local interests. The average annual maintenance cost during the past 5 years was $106,900. Local cooperation. Fully complied with for the project adopted under authority of the River and Harbor Act of August 30, 1935. Modification adopted by the River and Harbor Act of Septem- ber 3, 1954, requires that local interests furnish free of cost to the United States all lands, easements, rights-of-way, and suitable spoil-disposal areas for the new work and subsequent maintenance when and as required; hold and save the United States free from damages due to the improvements; and that prior to construction, responsible local interests furnish assurances that they will install and maintain adequate tank-storage facilities at Ocean City for the handling of petroleum products. Terminal facilities. The facilities on the bay side of Ocean City include 2 storage basins, for pleasure and small commercial craft, and numerous privately owned pile-and-timber piers and bulkhead wharves. Facilities at the project harbor include a public landing about 1,000 feet long, several privately constructed bulkhead wharves open to the public for transaction of business with the owners, and a boat-repair yard with a marine railway capable of handling boats up to about 150 tons. The project harbor is served by the Baltimore, Chesapeake & Atlantic Railway, which has a spur line parallel to the harbor on the north side about 200 feet away. All the piers and wharves are accessible by highway. Adequate space is presently available for expansion of facilities as required. Terminal facilities for the channel across Sinepuxent Bay to Assateague Island consist of a county-owned timber-bulkhead landing at both the South Point and Assateague Island termini of the channel. Adequate space is available for expansion of these facilities. Operations and results during fiscal year.

Washington Harbor is located within the District of Columbia at the junction of the Anacostia River with the Potomac River which flows in a southeasterly direction 108 miles to the Chesapeake Bay. It is southerly 202 miles by water from Balti- more, Md., and northerly 195 miles from Norfolk, Va. (See U. S. Coast and Geodetic Survey Chart No. 560.) Previous projects. The original project for the Potomac River was adopted by the River and Harbor Acts of March 2, 1833, July 11, 1870, and August 2, 1882. For further details, see page 1791 of Annual Report for 1915, and page 295 of Annual Report for 1934. The River and Harbor Act of September 19, 1890, author- ized an allotment for work on the Anacostia River; joint reso- lution of Congress of April 11, 1898, made appropriation for a survey; and a project was adopted by the River and Harbor Act of June 13, 1902 (H. Doc. 87, 55th Cong., 3d sess., and Annual Report for 1899, p. 1443). For further details see page 430 of the Annual Report for 1932 and page 421 of Annual Report for 1938. Existing project. This project is a combination and extension of the latest projects for the Potomac River at Washington, D. C., and the Anacostia River, D. C. The project provides for: (1) 321 322 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Virginia Channel, from Giesboro Point to Francis Scott Key Bridge, 24 feet deep and 400 feet wide, with the width increased as necessary to afford a low water cross-section area of 25,000 square feet; (2) Washington Channel, from Hains Point to the head of Washington Channel, 24 feet deep and 400 feet wide; (3) Anacostia River from Giesboro Point to Anacostia Bridge, 24 feet deep and 400 feet wide, with turning basin 800 feet wide and approximately 2,400 feet long of same depth opposite the Naval Gun Factory; (4) Anacostia River from Anacostia Bridge, 24 feet deep and 200 feet wide to turning basin 400 feet square of same depth at foot of Fifteenth Street SE. The channel lengths including turning basins are: Virginia Channel, 25,000 feet; Washington Channel, 10,000 feet; and Anacostia River, 15,000 feet; (5) operation and maintenance of the inlet gates and lock and the outlet gates of the Tidal Basin constructed under a previous project to flush the Washington Channel. The plane of reference is low water datum which is 0.35 foot below mean low tide as observed from 1932 to 1942. Tidal ranges are: Mean, 2.9 feet; irregular, 4.5 feet; and extreme, 10.7 feet. The estimate of cost to the Federal Government for new work, revised in 1955, is $572,000, exclusive of amounts expended under previous projects. The average annual maintenance cost during the past 5 years was $73,394. The existing project was adopted by the River and Harbor Act of August 30, 1935 (Rivers and Harbors, Committee Doc. 22, 74th Cong., 1st sess.). The latest published maps are in the project document. Local cooperation. Not required. Terminal facilities. On the Virginia Channel (Georgetown waterfront) there are 10 wharves generally of the bulkhead type, of timber, stone, and concrete, privately owned. Railroad and crane service are available at a number of the wharves. On the Washington Channel there are 2 yacht basins with a total capacity of 198 yachts, under jurisdiction of the District of Columbia and 12 wharves of open-pile and bulkhead construction, all owned by the Federal Government, but most of which are leased to private parties or serve governmental agencies. On the Anacostia River there are about 23/4 miles of commercial waterfront on which are located 7 privately owned and 2 governmental wharves, and 3,500 linear feet of bulkhead with slips for governmental agencies. In addition, there are numerous small stagings and floats used by yacht clubs for mooring small boats. Some of the wharves and slips have transfer and rail facilities. The wharves of the Washington Harbor are only open to the public by special arrangement, except for the District of Columbia fish wharves on the Washington Channel. Terminal facilities, except for those in the Washington Channel, are considered adequate for existing commerce. Operations and results during fiscal year. The Tidal Basin gates were repaired and operated by hired labor throughout the year at a cost of $10,958. Maintenance dredging was performed by Government plant RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 323 and hired labor at the wharf of the Corps of Engineers in the Anacostia River during the month of April 1957. A total of 10,000 cubic yards of material was dredged and deposited in a disposal area at Daingerfield Island, Va., at a cost of $4,300. As a result of an overestimate of quantities removed from the Washington Channel by a dredging contractor during the pre- ceding fiscal year, a credit of $11,757 was received during the current fiscal year. Replacement of triangulation stations along the Virginia Channel was performed during the fiscal year at a cost of $856. The cost of supervision and administration for the year was $2,358. The net total costs for the year were $6,715, all for maintenance. Condition at end of fiscal year. The existing project was started in April 1937 and was about 50 percent complete at the end of the fiscal year. The channels and basins in the Anacostia River are complete and those at the forks of the channel at Hains Point are partially complete. Except for dredging between the limits of 2,000 feet above and 3,000 feet below the Memorial Bridge, no new work has been done downstream of Key Bridge in Virginia Channel. The controlling depths in the channels throughout the harbor were as follows: Name of channel Codeptrollin Date Potomac River, Virginia Channel from Giesboro Point to Key 4 Bridge__ ------------------------------------------------ 14.6feet June1956.

The water chestnut, botanically known as Trapa natans, is an annual fresh-water plant infesting the navigable portions of the Potomac River and its tributaries between Key Bridge in the District of Columbia and Maryland Point, 48 miles downstream of Washington, D. C. Washington, D. C., is located 108 miles upstream of the mouth of the river. At the height of infestation in 1939, it covered about 10,000 acres of navigable waters between these limits. (See U. S. Coast and Geodetic Survey Charts Nos. 559 and 560.) Existing project. This provides a plan for complete eradication of the water chestnut from the Potomac River and its tributaries at and below Washington, D. C., by (1) 4 years of mechanical cutting in heavily infested areas with manual removal of scattered plants; (2) 3 years of intensive patrol and manual removal of scattered plants; (3) 2 years of concentrated patrol during the growing season; (4) 6 years of patrolling the entire area every 2 years. The tidal ranges are: Mean, 1.1 feet at Maryland Point and 2.9 feet at Washington; irregular, 2 feet at Maryland Point and 4.5 feet at Washington; extreme, approximately 7.5 feet at Maryland Point and 10.7 feet at Washington. The estimate of cost to the Federal Government, made in 1947, was $142,000, which is the total of annual costs over a 15-year period, decreasing from $32,000 during the first year to $3,500 for the ninth year and an average of $1,000 for each of the 6 years thereafter. This is an average of $9,467 annually for the 15 years. If a longer period is required, the average annual cost for each subsequent year is estimated to be $1,000. The work is maintenance. The existing project was authorized by the River and Harbor Act approved May 17, 1950 (H. Doc. 113, 81st Cong., 1st sess.). The latest published map is in the project document. Operations and results during fiscal year. Removal of water chestnut growth was in progress during July and August 1956 in the following areas: Washington Harbor, Potomac River at Alexandria, Va., Potomac River at Mt. Vernon, Va., Occoquan Creek, Va., and Potomac River below Washington, D. C., by Government plant and hired labor at a total cost for the year of $7,837, for maintenance. Condition at end of fiscal year. Work on the elimination of water chestnut has been in progress since 1939 under allotments for maintenance of five existing river and harbor projects. Prior to the adoption of this project and through the fiscal year ending June 30, 1950, a total of 25,000 acres of the growth has been cut and recut from the Potomac River and its tributaries between Washington, D. C. and Maryland Point. All infested areas have been cut at least once. Two years of mechanical cutting in heavily infested areas and manual removal of scattered plants as listed for accomplishment under the eradication schedule for the exist- ing project have been completed under maintenance of other 326 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 existing river and harbor projects prior to adoption of the eradication project. Prior to the adoption of the project and through the fiscal year ending June 30, 1950, maintenance funds in the amount of $310,187 were expended for removal of water chestnut. This amount includes $10,000 allotted under section 3 of the River and Harbor Act of July 3, 1950, and $10,000 allotted under section 3 of the River and Harbor Act of October 17, 1940, to ten tribu- taries of the Potomac River, and the following maintenance funds from existing river and harbor projects in the affected area: Washington Harbor, D. C., $19,726; Potomac River at Alexandria, Va., $22,023; Potomac River below Washington, D. C., $200,937; Potomac River at Mt. Vernon, Va., $18,202; and Occoquan Creek, Va., $29,300.

By act, Public Law 378, 64th Congress, approved March 3, 1917, the furnishing of water to adjacent Maryland areas from the District of Columbia water system was authorized by Congress; by act, Public Law 119, 69th Congress, approved April 14, 1926, the furnishing of water to Arlington County, Va., from the District of Columbia water system was authorized by Congress; and, by act, Public Law 118, 80th Congress, 1st session, approved June 26, 1947, the furnishing of water to Falls Church or any competent state or local authority in the Virginia metropolitan area, similarly, was authorized. A description of the District of Columbia water supply system and of previous capital-improvement and operation-and-main- tenance projects is printed on pages 2206-2208 and 2218-2220 of the Annual Report of the Chief of Engineers, 1930; in an informa- tion pamphlet published June 1939 and revised December 1950; and in House Document 480, 79th Congress, 2d session. Local cooperation. Prior to July 1, 1880, the expenses of the Washington Aqueduct for construction, operation, and mainte- nance were paid wholly out of the revenues of the United States. From July 1, 1880 to June 30, 1882, the expenses of operation and maintenance were paid one-half by the United States and the other half out of the general revenues of the District of Columbia. From July 1, 1882 to June 30, 1898, one-half of construction costs were charged to a capital account on the books of the Treasury to be repaid by the District of Columbia from water rents with interest at 3 percent. From July 1, 1898 to June 30, 1916, the expenses of construction, operation, and maintenance were paid one-half from surplus general revenues of the District of Columbia and the other half from the United States Treasury. From July 1, 1916 to June 30, 1927, the expenses of construction were paid 60 percent out of 336 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the general revenues of the District of Columbia and 40 percent by the United States. From July 1, 1927 to date, all expenses for construction have been paid out of the water revenues of the District of Columbia. From July 1, 1916 to date, the expenses of operation and maintenance have been paid wholly out of the water revenues of the District of Columbia. From April 1953 to June 30, 1957, the sum of $8,100,000 was borrowed from the United States Treasury in installments, to finance the expansion and improve- ment of the District of Columbia water system as authorized by Public Law 533, 81st Congress, 2d session, approved June 2, 1950 and as amended by Public Law 364, 83d Congress, 2d session, approved May 18, 1954. By Public Law 280, 66th Congress, 2d session, approved June 10, 1920, the sum of $25,000 was appropriated wholly from United States revenues to prepare, among other things, a report to assure an increased and adequate water supply for the District of Columbia. The report submitted, known as the Tyler report, was the basis for the improvements constructed from 1922 to 1927. Included in the District of Columbia appropriation acts of 1941 and 1942, approved June 12, 1940 and July 1, 1941, respectively, a total of $40,000 was appropriated from the water fund, District of Columbia, for the preparation of a report "for the development of a plan to insure an adequate future water supply for the District of Columbia". This report, published as House Document 480, 79th Congress, 2d session, contains the comprehensive plan and program for the improvements and additions to the water system. Annually, since July 1, 1920, on a percentage basis and, since July 1, 1924, on a lump-sum basis, the United States has contrib- uted to the support of the District of Columbia but, prior to July 1, 1947, no part of such annual percentage or lump-sum con- tribution has been allocated to the water fund, District of Columbia. Beginning with the fiscal year 1948 and continuing through June 30, 1954, pursuant to Public Law 195, 80th Congress, 1st session, approved July 16, 1947, an annual amount of $1,000,000 was authorized for water consumed by the Federal Government. Public Law 364, 83d Congress, 2d session, approved May 18, 1954, which is known as the "District of Columbia Public Works Act of 1954", provided for payment by the Government of the United States for all water and water services furnished, and increased the authority for borrowing. Public Law 533, 81st Congress, 2d session, approved June 2, 1950, authorized the Secretary of the Treasury to lend with a limit of $23,000,000, to the Commissioners of the District of Columbia, such sums as may hereafter be appropriated to finance expansion and improvement of the water system when sufficient funds therefor are not available from the District of Columbia Water Fund established by law (D. C. code 1940 edition, title 1943, ch. 15). The above public law was amended by Public Law 364, 83d Congress, 2d session, approved May 18, 1954, by striking RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 337 the figures "23,000,000" and inserting in lieu thereof the figures "35,000,000". Operationsand results during the fiscal year. An uninterrupted and adequate supply of purified water was furnished to the District of Columbia; to Arlington County, Va., and Falls Church, Va.; and to Federal establishments in Arlington County, Va., and in Montgomery and Prince Georges County, Md. The total con- sumption for the year was 55,902,214,000 gallons; the maximum daily consumption was 238,430,000 gallons and the average daily consumption was 153,160,000 gallons. Based upon the estimated average number of consumers of 1,000,000 in the District of Columbia and 169,000 in Arlington County, the average per capita daily consumption was 131 gallons. The average daily con- sumption in the District of Columbia alone was 135,160,000 gallons or an average per capita daily consumption of 135 gallons. The average daily amount of water furnished to Arlington County and Falls Church, Va., was 18,000,000 gallons or an average per capita daily consumption of 107 gallons. The gross cost of $489,408.75 for the supply of water furnished Virginia com- munities was reimbursed to the Water Fund, D. C. The average daily consumption of water in all Federal Government establish- ments including parks, zoological garden, etc., was 28,308,718 gallons. A total of 132,591,000 gallons or an average of 360,000 gallons per day was delivered to Maryland communities during the fiscal year 1957 by the Water Division, D. C., through connec- tions to the Washington Suburban Sanitary Commission's system. On June 23, 1952, fluoridation equipment was put in service and the application of sodium silicofluoride started and has been continued throughout fiscal year 1957. The average turbidity of the raw water from the Potomac River was reduced from 39 parts per million to 0.0 parts per million and the average bacterial content was reduced from 2,310 to .83 per milliliter. Analyses were made for coliform bacteria on 107,104 tubes of water taken from 128 sampling points in the collection, purification, and distribution systems. After sterilization of the filter effluent, the average most probable number of coliform bacteria per 100 milliliters was found to be .049 at Dalecarlia and .096 at the McMillan filter plant. The average calcium carbonate alkalinity of the filtered water was 59 parts per million and the average pH value was 7.7 from the Dalecarlia filter plant, and 57 and 7.7, respectively, from the McMillan filter plant. The average hardness was 102 parts per million from Dalecarlia and 97 parts per million from McMillan. Fluorine content of 3,686 water samples was determined. In fiscal year 1957, the direct operating cost of water treated and delivered to the system per million gallons was $35.87 as compared with the cost of $37.08 per million gallons in fiscal year 1956. The overall cost of water delivered, including depreciation and interest was $81.21 per million gallons as compared with $75.48 in fiscal year 1956. 338 REPORT OF THE CHIEF OF ENGINEERS, U. S.

Control. All funds were expended in conformity with the legislative provision contained in the annual appropriation act which is as follows: Nothing herein shall be construed as affecting the superintendence and control of the Secretary of the Army over the Washington Aqueduct, its rights, appurtenances, and fixtures connected with the same, and over appropriations and expenditures therefor as now provided by law. Condition at end of fiscal year. The intakes, conduits, reser- voirs, filter plants, pumping stations, mechanical equipment, and structures were in good condition generally. For several years, however, the summertime demands upon the filtered water supply system have exceeded combined plant nominal capacity, and operation has been in the overload category. During summertime maximum consumption demand periods, the basic raw-water supply was exceeded and standby raw-water pumping equipment had to be utilized. Construction work authorized with "no year" funds not previously reported as completed was as follows: Circulating facilities in 1st and 2d high service reservoirs 79 percent; modification to provide quality control of filtered water 67 percent; Dalecarlia pumping station, intake, conduit, and con- trol chamber 82 percent; conduit repairs (periodic) 100 percent; acquisition of supplementary land 81 percent; purchase and instal- lation of federal meters 97 percent; Little Falls pumping station, dam, and tunnel 70 percent; utility relocations and system inter- connections 75 percent; hydro station improvements 100 percent; and 3d high service reservoir at Reno (first half, 90 percent).

Hampton Roads is a natural harbor located 300 miles south of New York and 180 miles south of Washington, D. C. Its principal tributaries are the James River, affording a natural deep harbor at Newport News, Va.; the Elizabeth River, with its Southern, Eastern, and Western Branches, providing harbors for Norfolk and Portsmouth, Va.; and Hampton Creek serving the harbor at Hampton, Va. (See U. S. Coast and Geodetic Survey Charts Nos. 400 and 452.) Existing project. This provides for the collection and removal of drift in Hampton Roads and its tributary waters and author- izes the Secretary of the Army to allot such amounts as may be necessary for the work from appropriations for the maintenance and improvement of existing river and harbor works or from other available appropriations, and that this work shall be carried on as a separate and distinct project. It is wholly a work of maintenance. The purpose of the work is to afford relief from variable conditions of obstruction, and no advance estimate of the amount of work required and its proper cost can be made. The average annual maintenance cost during the past 5 years was $20,655. The existing project was authorized by the River and Harbor Act of May 17, 1950, as specified in the act. Terminal facilities. For a description of the terminal facilities on this project see this heading under "Norfolk Harbor" and "Channel to Newport News, Va." Operations and results during fiscal year.

(See U. S. Coast and Geodetic Survey Chart No. 452.) Existing project. This provides for the construction of a new railroad bridge to replace the existing outmoded, grossly mis- alined bridge. The new bridge will include a vertical-lift span 383 feet long, providing a horizontal clearance of 300 feet perpendicu- lar to the axis of the channel and a vertical clearance of 145 feet above mean low water in its fully raised position and 14.5 feet in ALTERATION OF BRIDGES-NORFOLK, VA., DISTRICT 381 its lowered position. The lift span will be flanked on the west by a through truss span about 180 feet long and 3 deck-girder spans each about 57 feet long, and on the east by 2 through truss spans each about 180 feet long and a single 57-foot deck-girder span. The notice to alter the existing bridge was signed by the Secre- tary of the Army on October 6, 1947, as authorized by the Truman- Hobbs Act of June 23, 1940. The estimated Federal share of the cost of new work, revised in 1957, is $2,340,000. The estimated cost to local interests, revised in 1956, is $390,000. Local cooperation. The Truman-Hobbs Act of June 23, 1940, provides that, upon notice to alter by the Secretary of the Army, the bridge owners shall (a) prepare and submit to the Secretary for approval, plans and specifications for the alteration of the bridge; (b) take bids for the alteration of the bridge in accordance with the approved plans; submit all bids to the Secretary together with a recommendation as to the most competent bid; submit a written guaranty that the total cost of the project will not exceed a stated sum; and upon authorization by the Secretary, proceed with the work of alteration; and (c) bear such part of the cost as determined by the Secretary to be attributable to the direct and special benefits which will accrue to the bridge owners as a result of the alteration, including the expectable savings in repair or maintenance costs; and that part of the cost attributable to the requirements of traffic by railroad or highway, or both, including any expenditure for increased carrying capacity of the bridge, and including such proportion of the actual capital cost of the old bridge or of such part of the old bridge as may be altered or changed or rebuilt, as the used service life of the whole or a part, as the case may be, bears to the total estimated service life of the whole or such part. In complying with the provisions of the Truman-Hobbs Act, the bridge owners have completed the following actions: (a) retained consulting engineers, completed necessary foundation investiga- tions, and prepared plans and specifications for the alteration of the bridge which have been approved by the Secretary of the Army; (b) taken bids for the construction of the substructure and approaches and superstructure of the new bridge in accord- ance with the approved plans and specifications; submitted all bids to the Secretary together with a recommendation as to the most competent bid; submitted a written guaranty that the total cost of the project will not exceed a stated sum; and, upon authori- zation by the Secretary, have awarded a contract for construction of the superstructure and approaches; (c) accepted an apportion- ment of cost prepared by the Chief of Engineers and approved by the Secretary of the Army; and (d) agreed to prosecute the project in three separable phases as Federal funds for each phase become available. Operations and results during fiscal year. Construction on the contract for substructure and grading, in progress at the beginning of the year was continued to the end of the year.

ATLANTIC INTRACOASTAL WATERWAY BETWEEN NORFOLK, VA., AND THE ST. JOHNS RIVER, FLA. (WILMINGTON DISTRICT) Location. This waterway is a sea-level route through coastal sounds and marine marshes, approximately parelleling the Atlan- tic Coast between Norfolk, Va., and the St. Johns River, Fla. (See U. S. Coast and Geodetic Survey Charts Nos. 830 to 842, inclusive.) The section within the Wilmington District begins at the Vir- ginia-North Carolina State line and extends generally southerly to Beaufort, thence southwestward to Cape Fear River, and thence westward to Little River, S. C., 308 statute miles. Previous projects. Adopted by River and Harbor Acts of July 4, 1836; March 3, 1837; July 7, 1938; June 18, 1878; March 3, 1879; June 14, 1880; March 3, 1881; August 2, 1882; August 5, 1886; September 19, 1890; March 3, 1905; June 25, 1910; and August 8, 1917. For further details, see page 1803 of Annual Report for 1915; pages 585, 587, and 589 of Annual Report for 389 390 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 1917; page 522 of Annual Report for 1926; page 497 of Annual Report for 1932; and pages 476 and 523 of Annual Report for 1938. Existing project. This provides for a waterway 12 feet deep at mean low water, with bottom widths varying from 90 feet in land cuts to 300 feet in open waters; for the construction, operation, and maintenance of suitable bridges; for a channel 10 feet deep at mean low water and 90 feet wide on the bottom in New River between the Intracoastal Waterway and the Atlantic Coast Line Railroad bridge at Jacksonville, N. C., 21 miles; for a side channel 12 feet deep and 90 feet wide to a turning basin of the same depth, 200 feet wide and 350 feet long, opposite the principal wharves at Swansboro; for an entrance channel 6 feet deep and 90 feet wide at New River Inlet, with connecting channel of same dimensions to the Intracoastal Waterway near the mouth of New River; for a channel 14 feet deep and 400 feet wide across the ocean bar at Masonboro Inlet, thence 12 feet deep and 90 feet wide to the chan- nel of the Intracoastal Waterway at Wrightsville by way of Banks and Motte Channels; a turning basin 15 feet deep having a maxi- mum width of 300 feet and length of 700 feet on the east side of Banks Channel near Masonboro Inlet, with three 15-pile dolphins therein; for an entrance channel in Peltier Creek, 6 feet deep, 50 feet wide, from the Intracoastal Waterway in Bogue Sound to and including a basin in Peltier Creek, 6 feet deep, 200 feet wide, and 600 feet long; for a yacht basin 230 feet wide, 450 feet long, and 12 feet deep near the town of Southport, connected with the waterway by a suitable channel of the same depth; and for salt- water-intrusion preventive measures in the vicinity of Fairfield, N. C., as follows: Construction of a pumping plant and a dam, with control gates and appurtenant works on Fairfield Canal near the Intracoastal Waterway; restoration and enlargement where necessary of Boundary Canal from the vicinity of Swindell Canal to the vicinity of Baum Canal, together with appurtenant works necessary to cut off inflow from other areas; and construction of dams with automatic floodgates across Swindell, Florida, Burris, and Baum Canals near Mattamuskeet Lake. That portion of the waterway north of the mouth of Neuse River is nontidal; variation in the water surface, due to winds, seldom exceeds 2 feet above or below mean stage. In the section between Beaufort and Cape Fear River the normal tidal range varies from 31/2 feet at the inlets to 1 foot at points between. The tidal range for New River varies from 31/2 feet at New River Inlet to 1 foot at the head of the marshes, and nothing at Tar Landing, 31 miles above. The mean range of tide in the section from Cape Fear River, N. C., to Little River, S. C., varies between 4.7 feet in the Cape Fear River, 4 feet at intermediate inlets, and 2 feet at points midway between inlets. The tide reached an elevation of 17.6 feet on October 15, 1954, at Holden Beach. The estimate of cost for new work, revised in 1956, exclusive of amounts expended on previous projects, is $10,056,000. Those portions of the project, including the tidal lock in the landcut of RIVERS AND HARBORS-WILMINGTON, N. C., DISTRICT 391 the Intracoastal Waterway near the Cape Fear River, jetties at Masonboro Inlet, 6 mooring basins in the Intracoastal Waterway, the 12-foot by 90-foot channel in New River to and including a basin at Jacksonville, N. C., and the 12-foot by 90-foot entrance channel in Peltier Creek from the waterway in Bogue Sound to and including a basin in Peltier Creek, are inactive, or are to be restudied, and are excluded from the foregoing cost estimate. The last approved costs for these portions were estimated to be: $1,750,000 (1954) for the tidal lock, $1,590,000 (1954) for jetties at Masonboro Inlet, $109,000 (1954) for the 6 mooring basins in the Intracoastal Waterway, $267,000 (1954) for the 12-foot project in New River, and $51,000 (1956) for the 12-foot project in Peltier Creek. The average annual maintenance cost during the past 5 years was $233,980, including $104,310 for operating and care of five highway bridges.

S. ARMY, 1957 Local cooperation. Complied with except for the following: a. Peltier Creek (H. Doc. 379, 81st Cong., 1st sess.), which re- quires that local interests give assurances satisfactory to the Secretary of the Army that they will provide without cost to the United States, all lands, easements, rights-of-way, and spoil-dis- posal areas necessary for the construction and subsequent mainte- nance of the project, when and as required; hold and save the United States free from damages due to the construction and sub- sequent maintenance of the works; and provide, without cost to the United States, a suitable area, accessible by road, for a public landing. Local cooperation requirements were adopted by the county of Carteret in a resolution on February 4, 1957, by the Board of County Commissioners. The guarantee of fulfillment of the assurances of local cooperation by Carteret County was accepted as satisfactory by the district engineer on February 21, 1957. The local sponsor was notified on February 21, 1957, that the public landing requirement of local cooperation would have to be met before any expenditure of funds is made for maintenance of the project. Because of changed conditions since the study of the project was completed, local interests contend that it is now impracticable to comply with all terms of local cooperation for the 12-foot project as authorized. They were advised of the proposed action of the Chief of Engineers in classifying the 12-foot proiect as inactive, with the provision of making the 6-foot by 50-foot project, as provided under emergency funds in September 1955, eligible for future maintenance. However, they were informed that all the provisions of local cooperation were to remain in full force and effect, even though the project is maintained to a depth of only 6 feet. The Board of County Commissioners of Carteret County adopted a resolution on May 2, 1957, agreeing to the decision of the Chief of Engineers. On June 26, 1957, the Chief of Engineers accepted the assurances of local cooperation as satis- factory, classified the 12-foot project as inactive, and proposed that the lesser project be maintained. Spoil-disposal areas neces- sary for the proiect are contemplated in the shallow waters along Bogue Sound; other provisions of cooperation will be met as the need arises. h. Vicinity of Fairfield (H. Doc. 723, 80th Cong., 2d sess.), which reouires that local interests provide, without cost to the United States, all lands, easements, and rights-of-way necessary for construction, maintenance, and operation of the project; hold and save the United States free from damages due to the con- struction works, and from all past damage in the area herein under consideration, which may have been caused by salt-water intrusion as a result of construction of the landcut of the Intracoastal Water- way: obtain and hold rights-of-way to present canals involved in the improvement, including the extinguishment of all present claims of rights, title, and interest to any of the canals; construct all necessary bridges and culverts for roads, and construct, enlarge, and clean all canals and ditches necessary for the efficient opera- tion of the project; and maintain and operate the works after RIVERS AND HARBORS-WILMINGTON, N. C., DISTRICT 393 completion. In June 1954, local interests were advised that before construction could start they would have to fulfill the pro- visions of local cooperation. They engaged an engineer in 1955 to make a survey of the area for the purpose of obtaining data to form a drainage district under North Carolina laws. That survey has been made. Local interests were duly organized pursuant to the provisions of Chapter 156 of the General Statutes of North Carolina, whereof by an order entered by the Clerk of the Superior Court of Hyde County, N. C., in Special Proceeding No. 1084 on March 21, 1957, Hyde County Drainage District No. 7 was established for the fulfillment of local cooperation requirements. Under the afore-mentioned proceeding Hyde County Drainage District No. 7 was vested with a fee simple title to a tract of land required for a pumping station site and with perpetual easements embracing all rights-of-way to present canals required for the project. A Board of Drainage Commissioners was appointed on April 2, 1957, by the court for the drainage district. Assurances of local cooperation requirements were adopted on April 12, 1957, by the Board of Drainage Commissioners of the district. The district engineer on April 22, 1957, accepted the resolution of assurances as a satisfactory guarantee of fulfillment of local co- operation requirements. Hyde County Drainage District No. 7 by warranty deed dated May 9, 1957, conveyed to the United States of America a fee simple title to a tract of land required for the pumping station site. The drainage district has the ability to operate the works after completion. c. Masonboro Inlet and connecting channels (H. Doc. 341, 81st Cong., 1st sess.), which requires that responsible local interests give assurances satisfactory to the Secretary of the Army that they will provide, without cost to the United States, all lands, ease- ments, rights-of-way, and spoil-disposal areas necessary for the construction and subsequent maintenance of the project, when and as required, and hold and save the United States free from damages due to the construction and maintenance of the improve- ments. Local cooperation requirements were adopted by the county of New Hanover in a resolution on December 10, 1956, by the Board of County Commissioners. The guarantee of fulfillment of the assurances of local cooperation by New Hanover County was accepted as satisfactory by the district engineer on December 10, 1956. Spoil-disposal area permits necessary for construction of the project were adequately provided by the local sponsor. Such areas required for future maintenance were guaranteed in the resolution; no difficulty is contemplated in getting local interests to provide all subsequent local cooperation requirements necessary for completion of the project. Terminal facilities. There are numerous wharves and landings along the present waterway, used mostly for shipping agricultural and timber products and for docking commercial and pleasure fishing boats. These wharves are of the open pile-and-timber type. The facilities are considered adequate for existing commerce. 394 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Operations and results during fiscal year. The work consisted of maintenance and new work dredging by contract, repair and replacing directional signs with Government plant and hired labor, painting of five highway bridges, operation and care of five bridges, engineering and design studies, condition and operation studies, and preparation of plans and specifications for construc- tion of salt-water-intrusion preventive measures. Between November 27, 1956, and March 27, 1957, the contract dredge Northwood II, on maintenance dredging, removed 312,200 cubic yards from the through waterway, 120,917 cubic yards from the channel to Jacksonville, and 47,361 cubic yards from the channel to New River Inlet at a cost of $188,452. Between February 23 and April 2, 1957, the contract dredge Pullen, on new work dredging, removed 321,324 cubic yards from the basin and the channels between Masonboro Inlet and the Intra- coastal Waterway at Wrightsville at a cost of $113,500. Between March 13 and April 19, 1957, the U. S. derrickboat Northeast and hired labor repaired and replaced directional signs along the waterway at a cost of $7,678. Between May 13 and June 30, 1957, painting of five highway bridges by contract was partially completed at a cost of $8,447. Engineering and design studies cost $1,086.

ROANOKE RIVER, N. C. Location. This stream rises in the Blue Ridge Mountains, west of Roanoke, Va., and flows southeasterly about 200 miles to Clarks- ville, Va., where it is joined by Dan River, its principal tributary; and thence in the same general direction about 198 miles and empties into the westerly end of Albemarle Sound, N. C. (See U. S. Coast and Geodetic Survey Chart No. 1228 and Post Route Map of North Carolina.) Existing project. This provides for dredging a channel 12 feet deep and 150 feet wide from the 12-foot contour in Albemarle Sound into Roanoke River and thence upstream to about 1 mile above Plymouth, N. C., 10 miles; thence a channel 10 feet deep and 100 feet wide to Hamilton, 53 miles; and thence a channel 8 feet deep and 80 feet wide to Palmyra Landing, 18 miles, with a cutoff 396 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 channel of like dimensions about 2 miles above Hamilton. Depths of channels are referred to mean low water. The rise and fall of the river from freshets is from 18 to 33 feet for about 70 miles below Weldon, but this fluctuation diminishes toward the mouth, the variations in water levels being from 1 to 2 feet in the lower 15 or 20 miles. The total length of channels included in the project is 81 miles. The cost to the Federal Government for completed work was $404,600. The 50-mile portion of the project providing for a channel 5 feet deep and 50 feet wide to Weldon, N. C., by dredging, snagging, and regulation is inactive and is excluded from the fore- going cost estimate. The cost of this portion, as last approved in 1955, is $234,400. The average annual maintenance cost during the past 5 years was $14,450.

Between that point and Hamilton there are 10 wharves. Between Hamilton and Halifax there are 13 log landings. These facilities appear to be adequate for existing commerce. Operations and results during fiscal year. The work consisted of clearing and snagging with Government plant and hired labor, and maintenance dredging by contract. Between November 23, 1956, and January 31, 1957, and between May 27 and June 18, 1957, the U. S. derrickboat Northeast with hired labor removed obstructions from the channel and banks and repaired and replaced mile boards between the mouth of the river and a point 79 miles upstream. The costs were $22,811. Between April 2 and 25, 1957, the contract dredge Savannah removed 79,718 cubic yards from shoals in the mouth of the river. The costs were $40,283. Total costs were $63,094 for maintenance. Condition at end of fiscal year. The existing project has been completed to the practicable limit. Dredging to obtain the present project dimensions from the mouth to Palmyra was commenced in September 1940 and completed in August 1941. At the close of the fiscal year the limiting depths at local mean low water were as follows: Between Albemarle Sound and 1 mile above Plymouth, 12 feet; thence to Hamilton, 7.6 feet; thence to Palmyra, 2.4 feet; and thence to Weldon, 1 foot. The total costs under the existing RIVERS AND HARBORS-WILMINGTON, N. C., DISTRICT 397 project to June 30, 1957, were $404,584 for new work and $307,572 for maintenance, a total of $712,156.

STUMPY POINT BAY, N. C. Location. Stumpy Point Bay is a circular indentation 2 miles in diameter on the mainland side near the northerly end of Pamlico Sound. The town of Stumpy Point is on the northeasterly shore of the bay and the hamlet of Lake Worth is on the northwesterly shore. Existing project. This provides for a channel 7 feet deep at mean low water, 75 feet wide, and about 8,000 feet long, from the 7-foot contour in Pamlico Sound through Stumpy Point Bay to Lake Worth, with a boat basin of the same depth, 50 feet wide by 600 feet long, at the inner end. Lunar tides are imperceptible. Normal variations in the water surface due to wind action seldom exceed 1 foot, but may be as much as 5 feet during severe storms. The cost to the Federal Government for the completed project was $40,600. The average annual maintenance cost for the past 5 years was $7,440. The existing project was adopted by the River and Harbor Act of June 30, 1948 (H. Doc. 422, 80th Cong., 1st sess.). The latest published map is in that document. 400 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Local cooperation. Fully complied with. Terminal facilities. At Lake Worth the bulkheads in the exist- ing basin provide about 550 linear feet of berthing space, and a wholesale fish house provides about 250 linear feet. Part of the space along the bulkheads is publicly owned. There are numer- ous small, cheaply constructed wharves along the shore of Stumpy Point Bay. No mechanical freight-handling devices are available. The facilities are considered adequate for existing and prospective commerce. Operations and results during fiscal year. The work consisted of maintenance dredging. Between August 5 and 14, 1956, the contract dredge Hampton Roads removed 96,861 cubic yards from the channel and basin, at a cost of $36,629.

FAR CREEK, N. C. Location. Far Creek is in Hyde County, N. C., and flows east- erly into Pamlico Sound about 95 miles south of Norfolk, Va. (See U. S. Coast and Geodetic Survey Chart No. 1232.) Existing project. This provides for a channel 12 feet deep and 100 feet wide from that depth in Pamlico Sound along the general alinement of the existing channel through the wide section of the creek, and thence 12 feet deep and 80 feet wide to about 200 feet below the highway bridge at Engelhard, with a turning basin of the same depth with maximum width and length of about 200 feet and 900 feet, respectively, at the head. The total length of channels included in the project is about 2.7 miles. There is some lunar tide in Pamlico Sound, but the principal variations in the level of the water surface are due to winds. Ordinarily winds cause a variation of about 1 foot, while severe storms will double or triple this variation. The cost to the Federal Government for the completed project was $164,596. The average annual maintenance cost for the past 5 years was $4,460. RIVERS AND HARBORS-WILMINGTON, N.

WALLACE CHANNEL, PAMLICO SOUND, N. C. Location. Wallace Channel extends generally northwest from the inlet gorge of Ocracoke Inlet at the Atlantic Ocean, through an inner bar to the 12-foot depth in Pamlico Sound, a distance of 404 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 about 7.4 miles. (See U. S. Coast and Geodetic Survey Charts Nos. 418, 419, and 1231.) Existing project. The project provides for a channel 12 feet deep and 200 feet wide in Wallace Channel, from that depth in the Ocracoke Inlet gorge to Pamlico Sound. The normal tidal varia- tion of the water surface is about 2.5 feet in the gorge with wind tides of about 2.5 feet in Pamlico Sound. Tides have reached over 7 feet during severe storms. This project was authorized by the River and Harbor Act of September 3, 1954 (H. Doc. 453, 81st Cong., 2d sess.). This document contains the latest published maps. The cost of new work to the Federal Government for the com- pleted project was $54,000. (See emergency maintenance work done on this project under authority of section 3 of the River and Harbor Act approved March 2, 1945 (Annual Report for 1955).) Local cooperation. Fully complied with. Terminal facilities. Since this is a through waterway, no ter- minal facilities are necessary. Adequate terminal facilities are available at ports on connecting waterways to care for present and prospective commerce over Wallace Channel. Operations and results during fiscal year. The work consisted of new work dredging. Between July 1 and 23, 1956, the contract dredge Savannah removed 111,799 cubic yards from the channel at a cost of $41,769. Condition at end of fiscal year.

WATERWAY CONNECTING PAMLICO SOUND AND BEAUFORT HARBOR, N. C. Location. This waterway begins at the southeast corner of Pamlico Sound, passing southwesterly through Wainwright Slough, Core Sound, and The Straits, to Beaufort Harbor, a total length of 33.9 miles. (See U. S. Coast and Geodetic Survey Chart No. 1233.) Existing project. This provides for a channel 7 feet deep at mean low water and 75 feet wide from Pamlico Sound to Beaufort Harbor by way of Wainwright Slough, Core Sound, and The Straits; also for an alternative route of the same width and depth through Back Sound by way of channels at east and west ends of RIVERS AND HARBORS-WILMINGTON, N. C., DISTRICT 405 Harkers Island; for a channel 7 feet deep and 75 feet wide from the main channel in Core Sound to the town of Atlantic; for a side channel 5 feet deep, 75 feet wide, with basin 150 feet by 130 feet, same depth, at Davis; for a side channel 7 feet deep, 75 feet wide, with basin 200 feet by 500 feet, same depth, at Sealevel; and for a side channel 6 feet deep, 60 feet wide, with basin 100 feet by about 600 feet, same depth, at Marshallberg. On June 14, 1948, the Chief of Engineers approved transfer of the Taylors Creek reach of this project to the project for Beaufort Harbor, N. C. (H. Doc. 111, 81st Cong., 1st sess.). The estimate of cost for new work, revised in 1957, is $178,000, exclusive of amounts expended by other agencies. The channel and basin at Sealevel has been restored to active status, and is thus included in the foregoing cost estimate. The average annual maintenance cost for the past 5 years was $9,340.

Local cooperation. The River and Harbor Act of March 2, 1945, provided that local interests furnish, free of cost to the United States, all necessary rights-of-way and spoil-disposal areas for new work and subsequent maintenance, remove all structures from the area to be dredged, release the United States from all claims for damages incident to work of improvement, and pro- vided further that local interests be required to contribute $1,000 toward the cost of dredging the side channel and basin at Sealevel. The River and Harbor Act of May 17, 1950, provides that respon- sible local interests furnish, without cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas necessary for the construction of the project and subsequent maintenance, when and as required; hold and save the United States free from all damages due to the construction and subsequent maintenance of the project; and provide at their own expense suitable space for a public landing at Marshallberg, open to all on equal terms. Local cooperation requirements were adopted by Carteret County in a resolution by the Board of County Commissioners on (1) August 6, 1956, for construction of two channels near the east and west ends of Harkers Island and a harbor and approach channel at Marshallberg and on (2) May 6, 1957, for a side channel and turning basin at Sealevel. The assurances of ful- fillment of local cooperation requirements were accepted as 406 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 satisfactory by the district engineer on September 28, 1956, and May 15, 1957, respectively. Carteret County by deed dated October 25, 1956, conveyed a perpetual easement to the United States of America for a right-of-way for the basin at Marshallberg, also furnished all required spoil permits for dredging operations. The county of Carteret can be expected to obtain title to and to dedicate a public landing at Marshallberg by August 31, 1957. The $1,000 was contributed toward the cost of dredging at Sea- level, by Carteret County, on May 17, 1957. The county was ad- vised June 10, 1957, of the approval of a public terminal proposed by local interests at Sealevel and an easement title to Carteret County thereunto is estimated to be finalized by July 31, 1957. Local sponsor appears willing and competent to comply with all subsequent local cooperation requirements of the project. Terminal facilities. Between Pamlico Sound and the southern end of Core Sound there are 15 small wharves, which are open to all when not required by the owners. Marshallberg has 4 privately owned wharves with about 700 feet of berthing space and a public dock with 200 feet of berthing space. Additional wharves are needed at several of the communities along Core Sound. Operations and results during fiscal year. The work consisted of new work dredging and preparation of plans and specifications for new work dredging in the side channel and basin at Sealevel, N. C. Between January 23 and February 12, 1957, the contract dredge Marion removed 60,422 cubic yards of material from the entrance channel and basin to Marshallberg, N. C., at a cost of $22,874. Between February 13 and April 13, 1957, the contract dredge Marion removed 257,241 cubic yards of material from connecting channels at the east and west ends of Harkers Island, N. C., at a cost of $86,750. Preparation of plans and specifications for new work dredging at Sealevel, N. C., cost $425. Cost incurred for maintenance dredging in fiscal year 1957 was $99. The total costs during the fiscal year were $110,049 for new work and $99 for maintenance, a total of $110,148. Condition at end of fiscal year. The existing project was about 95 percent completed. That portion of the project providing for a through channel from Pamlico Sound to Beaufort Harbor was commenced in August and completed in December 1934; the side channel to Atlantic was commenced in January and completed in February 1937; the side channel and basin at Davis, N. C., were commenced and completed in January 1948; the entrance channel and basin at Marshallberg were commenced in January and completed in February 1957, and the channels at the east and west ends of Harkers Island were commenced in February and completed in April 1957. No dredging has been done on the contract for the 7- by 75-foot side channel and the basin at Sealevel, N. C.

Recommended modifications of project. On October 26, 1954, the Chief of Engineers recommended modification of the Morehead City Harbor project to provide for a bar channel through Beaufort Inlet, 35 feet deep and 400 feet wide, increased to 600 feet at the bend, thence an inner channel 35 feet deep and 300 feet wide to an enlarged turning basin, 35 feet deep, all at an estimated cost of $1,197,000 for construction, subject to certain conditions of local cooperation. This report was submitted to Congress by the Secretary of the Army on June 10, 1955. Local cooperation. Fully complied with. Terminal facilities. There are 26 wharves along the main waterfront of the town, with a total frontage of about 1,250 feet. The marine terminals provide 2,731 feet of berthing space with a depth alongside of 27 feet at mean low water, and facilities for transfer of cargoes between rail and water carriers. The exist- ing facilities are considered adequate for existing and prospective commerce. For further details, see Port Series No. 16 (1954), Corps of Engineers. Operations and results during fiscal year. The work consisted of maintenance dredging by contract and by Government plant and hired labor, replacement of survey and dredging ranges by contract, and condition and operation studies.

Piers and slips extend for about 1 mile along the eastern waterfront of the city of Charleston, and an additional mile is covered by marginal wharves. The South Carolina State Ports Authority operates the terminal at Columbus Street, large piers near Market Street, and the beltline rail- way serving all wharves and warehouses, and connecting with trunklines entering the city. Modern facilities are also at the Southern Railway coal pier and the wharves of the Standard Oil Co., the Charleston Shipyards, Inc., the Seaboard Air Line Rail- road, the Southern Railway Co., and the Concentration Warehouse and Compress Co. RIVERS AND HARBORS-CHARLESTON, S. C., DISTRICT 427 On Cooper River above the navy yard a compress and ware- house company has a marginal wharf 750 feet long; the Texas Corp., the Sinclair Refining Co., and the Cooper River Terminals, Inc., maintain piers at their properties; and the South Carolina State Ports Authority operates a large terminal capable of berth- ing four cargo vessels. The facilities are considered adequate for existing commerce. For further details, see Port Series No. 13, revised 1950, Corps of Engineers. Operations and results during fiscal year. The pipeline dredge Admiral performed maintenance dredging by contract during the period September to December 1956 in the inner harbor on shoals 5A, 6 and 6A, including a realinement of channel in the vicinity of shoal 5A, removing a total of 1,613,823 cubic yards of material at a cost of $571,245. The marl portion of material removed from the realined channel at shoal 5A was placed as a hydraulic fill forming a base for a channel contraction dike being constructed at shoal 5A. The dredges Admiral and Floridaperformed maintenance dredg- ing by contract during the period May and June 1957 in the inner harbor at shoals 1, 2, 3, 4, and 6, removing a total of 460,000 cubic yards of material at a cost of $146,594. The dredge Admiral also performed maintenance work during the same period as follows: removed 335,030 cubic yards of marl from the chan- nel at shoal 6, at a cost of $221,120, and placed it as hydraulic fill forming the bases for channel contraction dikes being con- structed in the vicinity; and also stripped 100,000 cubic yards of undesirable muck from the marl borrow area in the channel in the same operation, at a cost of $27,000. An incidental benefi- cial effect of dredging the hydraulic fills was to provide advance maintenance dredging over a large portion of shoal 6 to an average depth of 46 feet. Costs in connection with procurement by the Government of sheet steel piling for construction of the contraction dikes through June 30, 1957 were $235,460. Govern- ment costs in connection with the hydraulic fills for the shoal 6 contraction dikes, and for continuation of field surveys, borings, and engineering and design work for the dikes were $68,444. The Waterways Experiment Station reproduced a limited num- ber of copies of appendixes 1, 2, and 3 of the report of the model study to reduce maintenance dredging in Charleston Harbor. The channel realinements and contraction dikes are remedial works resulting from these studies. Costs in connection with the model and prototype studies were $7,958. The Carolina Dredging Co. performed improvements to Bay- view Acres Spoil Area by contract as follows: Constructed 3,099 feet of new diking, rebuilt 3,200 feet of existing diking, cleaned out 3,100 feet of existing drainage canal and installed five 24-inch automatic drainage gates at a total Government cost of $22,091. In addition work was performed in connection with mosquito control in spoil area at a cost of $2,113. The cost of surveys and supervision was $7,676. The total cost for the year was $1,309,701 for maintenance. Condition at end of fiscal year. The jetties protecting the 428 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 entrance channel across the bar were completed in 1895. The existing project was completed during January 1956 except for the national defense portions of the project. Surveys during the latter part of the fiscal year in the entrance and Cooper River channels showed a controlling depth of 35 feet for a 600-foot width from the 35-foot contour in the ocean to the north end of Drum Island; thence 34 feet for a 400-foot width to the head of the project at shoals 1, 2, 3, and 4 where the controlling depth is 30.5 feet for a 400-foot width. A survey in Shem Creek during June 1956 showed a controlling depth of 10 feet for full project width. The costs of the existing project have been $2,057,964 from regular funds and $57,813 from public works funds, a total of $2,115,777 for new work, and $9,567,583 from regular funds and $56,087 from public works funds, a total of $9,623,670 for maintenance; a grand total of $11,739,447 exclusive of $600 contributed funds.

Location. The Yadkin River rises on the eastern slope of the Blue Ridge Mountains in western North Carolina, flows generally northeasterly 100 miles to the vicinity of Donnaha, N. C., thence southeasterly 104 miles to its confluence with the Uwharrie River near Badin, North Carolina, where its name changes to the Great Pee Dee River. (See U. S. Geological Survey map of North Carolina.) Existing project. The Flood Control Act approved July 24, 1946, authorized the construction of four flood control dams in the upper Yadkin River basin, 2 on the Yadkin River above Wilkesboro, N. C., and 2 on the Reddies River, a tributary stream. Studies made subsequent to the authorization act established the economic advantage of providing the needed flood control storage in two reservoirs, one on the Reddies and one on the Yadkin, rather than in four reservoirs as originally planned. Present planning con- siders only the two-reservoir plan.

WILKESBORO RESERVOIR, YADKIN RIVER, N. C. Location. The Wilkesboro Dam site is on Yadkin River, about 6 miles upstream from Wilkesboro, N. C. At full flood-control pool elevation, the reservoir will extend 15.7 miles up the Yadkin River to the Wilkes-Caldwell County line. Existing project. The existing project for the Yadkin River was authorized by the Flood Control Act approved July 24, 1946. A review report dated August 14, 1953, established that modifica- tion of the authorized multiple-reservoir plan to provide a single reservoir at the Wilkesboro site would be more economical. The estimated cost, revised in 1957, is $6,570,000 for design and construction, $764,000 for lands, and $716,000 for relocations and rights-of-way; a total of $8,050,000. Local Cooperation. None required. Operations and results during fiscal year. In compliance with request of Senate Appropriations Committee, an investigation of alternate plans providing reservoirs on tributary streams in lieu of the Wilkesboro Reservoir on the main stem of the Yadkin River was made in fiscal year 1957. Engineering and economic studies of three alternate plans providing from 5 to 31 reservoirs on tributary streams were made. These studies indicated that tributary reservoirs would be less effective for flood control than Wilkesboro Reservoir; that their cost would be more than double that for Wilkesboro Reservoir; and that none of the alternate plans for tributary reservoirs could be economically justified under prevailing benefit-cost criteria. In conjunction with the investigation of alternate plans, minor revisions were made in the 1956 restudy of Wilkesboro Reservoir benefits and costs which established the economic justification of the authorized project. The total cost for work accomplished during the year was $54,508. Condition at end of fiscal year. On the basis of the 1956 restudy of Wilkesboro Reservoir, and the 1957 investigation of alternate plans, it was determined that the authorized Wilkesboro Reservoir will provide for the best control and use of the water resources of the upper Yadkin River basin, and the project was reclassified from "deferred for restudy" to "active" status. 434 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The cost for new work for Wilkesboro Reservoir to June 30, 1957 is $87,840.

This section of the waterway connects Port Royal Sound, S. C., with Fernandina, Fla. (See U. S. Coast and Geodetic Survey Charts Nos. 838-841, inclusive.) Previous projects-between Savannah, Ga., and Fernandina, Fla. Previous improvements in this section were authorized by River and Harbor Acts of August 2, 1882; August 11, 1888; July 13, 1892, and March 3, 1905. For further details, see pages 1814, 1821-1823, Annual Report for 1915, and page 585, Annual Report for 1938. Existing project. This provides for a waterway 12 feet deep at mean low water and not less than 90 feet wide between Port Royal Sound, S. C., and Savannah, Ga.; for a waterway 12 feet deep at mean low water, with widths of 90 feet in landcuts and narrow streams and 150 feet in open waters, between Savannah, Ga., and Fernandina, Fla., to follow in general the alinement of the existing waterway, except for such cutoffs or other changes in the route as may be found desirable and justified by the resultant benefits to navigation; and for a suitable anchorage basin at Thunderbolt, Ga. The total distance from Port Royal Sound, S. C., to Fernan- dina, Fla., is 165 miles. The project also provides for the follow- ing: (1) removing logs and snags from Generals Cut, Ga.; (2) an alternative and more protected route 7 feet deep at mean low water from Doboy Sound to Brunswick Harbor, via Darien River, Three Mile Cut, Altamaha River, One Mile Cut, Buttermilk Sound, 437 438 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Mackay River, Back River, Clubbs Creek, and Plantation Creek; (3) a protected channel 7 feet deep at mean low water and 75 feet wide around St. Andrews Sound, extending from the main route of the waterway in Jekyll Creek through Jekyll Sound, Little Satilla River, Umbrella Cut, Umbrella Creek and its south branch, through Dover Cut to Dover Creek, thence up Dover Creek and through a narrow neck of land to Satilla River, thence through a landcut south of Todd Creek and through Floyd Creek to the main route of the waterway in Cumberland River; (4) a channel 5 feet deep at mean low water and 50 feet wide to connect Baileys Cut to Satilla River and Dover Creek, Ga., (5) a loop 8 feet deep at mean low water to reach the wharves at the southern end of Cumberland Sound; (6) an alternative route 9 feet deep and 150 feet wide in that part of Frederica River, Ga., not now traversed by the main route, at no additional cost to the United States. In general, the work is to be accomplished by dredging, supplemented by training walls as necessary. The mean tidal range between Port Royal, S. C., and Fernan- dina, Fla., is from 6 to 8 feet, with fluctuations from 11/ to 21/2 feet, due to winds and lunar phases.

The main 12-foot channel of the existing project was completed in 1941. The 7- foot protected route around St. Andrew Sound was completed in 1939. The training walls and closure dams were completed in 1912, and are in satisfactory condition. All other improvements were completed in 1932. Since March 1943, the previous route of the Intracoastal Water- way, through the westerly end of South Channel and the northerly end of Wilmington River, has been superseded by the route through the Elba-McQueens Island Cut and the northwesterly end of St. Augustine Creek. The former route will be maintained to a depth of 7 feet for traffic moving from Savannah to points south of Savannah Harbor and for northbound traffic from southern points below Savannah Harbor to Savannah, Ga. The main route had a controlling depth of 12 feet or more except as follows: October 1956, Ramshorn Creek (mile 568.1 to mile 569.0) 11 feet; Walls Cut (mile 572.3) 8 feet; Fields Cut (mile 573.4 to mile 573.9) 9 feet; June 1957, Elba-McQueens Island Cut (mile 576.6) 11 feet; St. Augustine Creek (mile 578.6) 11 feet; Wilmington River (mile 579.0 to 581.1) 11 feet; Hell Gate (mile 600.7) 11 feet; Florida Passage (mile 607.5) 11 feet; Creighton Narrows (mile 642.3) 11 feet; Rockdedundy River (mile 652.9) 10 feet; Buttermilk Sound (mile 663.0 to 663.3) 11 feet; MacKay River (mile 664.5) 11 feet; St. Simon Sound (mile 677.0 to 677.7) 11 feet; Jekyll Creek (mile 681.2 to 683.5) 10 feet.

The maintenance of the channels, anchorage basins, enlarge- ments at Drakies Cut, Kings Island, West Broad, and Barnard Streets, mooring dolphins near Fort Oglethorpe, and the existing training walls and jetties. The plane of reference is mean low water, which varies for different parts of the harbor. The mean range of tide is 7.6 feet at the upper end of the harbor and 7.1 feet at the lower end. Extreme ranges are about 10.5 feet and 11 feet, respectively. Tides below mean low water occur 6 or 7 times a month and minus 2-foot tides occur from 6 to 8 times a year. The improvement has increased the mean tidal range by about 2.8 feet at the upper end. The estimate of cost for new work, revised in 1956, is $9,110,000 exclusive of amounts expended on previous projects. The con- struction of bank protection and extension of permeable dikes in the upper reaches of the harbor are inactive and are excluded from the foregoing cost estimate. The last approved costs for these features were estimated to total $266,000 (1956). The average annual maintenance cost during the past 5 years was $1,287,543. Local cooperation. The River and Harbor Acts approved November 7, 1945, and July 24, 1946, impose the conditions that local interests shall: (1) Provide free of cost to the United States, all lands and rights-of-way required for the initial construction and subsequent maintenance when and as required; (2) hold and save the United States free from damages due to the construction works. The River and Harbor Act approved on September 3, 1954, in authorizing the construction of the new turning basin and exten- sion of the 34-foot channel further required that "local interests provide, free of cost to the United States, and prior to the initiation of any construction work, all lands, easements, rights- of-way and spoil areas necessary for this improvement and for the subsequent maintenance of the entire project." The mayor and aldermen of the city of Savannah on March 6, 1957, resolved to act as local assurer in securing necessary spoilage easements in Savannah Harbor. The conditions imposed on the local assurer by these acts have been complied with to date. 442 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 During the year, the "Twenty-five year spoilage plan, Savannah Harbor, Georgia" previously furnished the mayor and aldermen was modified. It was agreed that the city of Savannah would furnish a 25-year spoilage easement on approximately 466.47 acres located on the northeast bank of Back River opposite Hutchinson Island designated as Area 12 and, further, furnish assurance in the form of a resolution that an easement in per- petuity on the area immediately east of said Area 12 and extending along the northern side of Barnwell Island to the Missroon property and which said spoilage area will be designated as Area 13. The aforementioned two new spoilage areas are in substitu- tion for a portion of Hutchinson Island for which the requirement under the original 25-year plan was a 20-year easement and only short term easements have been available. The city has procured all easements and short term permits as required under the 25-year spoilage plan as modified and has furnished resolution in which assurance was given that, within one year from date of resolution, the city would furnish an easement on Area 13. The condemnation action (CA 3490, United States v. Pinckney, McLaws, Missroon, et al.) was amended to delete 1,616 acres not required; however, this proceeding has not been completely adjudicated and the surety bond in the amount of $70,000 is still in effect. In the past, the city of Savannah has acted in good faith, and its present efforts are evidence of its intent to achieve full compliance with the law. Terminal facilities. There are 48 piers and wharves to serve waterborne commerce of the port. These facilities, with the use of dolphins, have a combined berthing space of 28,054 feet, with depths of water alongside ranging from zero to 34 feet at mean low water. Five of these terminals are opposite the city on Hutchinson Island; the remaining 43 are on the south side of the river between 3 miles below and 6.8 miles above the center of the city. Thirteen piers and wharves are operated by railroads, 6 by oil companies, 2 by coal companies, 5 by ship repair companies, 14 by various private industries, and 1 by the Georgia Ports Authority. The site of a former shipyard has been acquired by the city of Savannah for future development of industrial sites. There is a large municipal wharf at the center of the city. All have railway and highway connections. The facilities are con- sidered adequate for existing commerce. For further details, see Port Series No. 14, Corps of Engineers (revised 1954). Operations and results during fiscal year. New work: The Design Memorandum was forwarded to higher authority Novem- ber 15, 1956 and approved December 5, 1956. Preparation of plans and specifications for deepening the channel to 34 feet and 400 feet wide from the presently authorized 34-foot channel in the vicinity of the Mexican Petroleum Corp. refinery to a point above the Georgia Ports Authority terminal with turning basin 34 feet deep at upper end was completed and the work advertised. Bids have been received three times and on each occasion the low RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 443 bid has been excessive; however, award is pending on the latest bid opening. The cost was $5,497. Maintenance: The contract dredge Clinton did maintenance dredging in the upper harbor during the period October 14 to December 30, 1956, removing 901,072 cubic yards of material at a cost of $154,653. The contract dredge Admiral worked in the inner harbor during the period March 3 to May 19, 1957, removing 2,206,875 cubic yards of material at a cost of $434,778. The United States pipeline dredge Gillespie worked in the upper and inner harbor during the period December 26, 1956 to June 30, 1957, removing 2,765,561 cubic yards of material at a cost of $425,546. The United States hopper dredge Gerig did mainte- nance dredging in the inner and outer harbor during the periods August 4 to September 10, 1956; October 1 to October 22, 1956; May 1 to June 30, 1957, removing 3,316,709 cubic yards of material at a cost of $433,884. Construction of spoil dikes cost $40,873. Dragging and sweeping the inner harbor cost $15,691. Condition and operation studies and supervision and ordinary maintenance cost $110,285. Included in this amount is $49,698 for operation of the model of Savannah Harbor. The sum of $9,023 was charged to the deferred account in connection with transportation of the United States dredge Gillespie pipeline. The total cost for maintenance was $1,624,733.

The 30-foot channel and extension of the 444 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 harbor above the Seaboard Air Line Railroad bridge was com- pleted February 5, 1948. The 34-foot channel was completed January 7, 1953. The 36-foot bar channel was completed April 15, 1951. The previous 30-foot project from the sea to old quarantine station was completed in 1930, and the rest of the 30- foot channel in 1937. That part of the previous 26-foot channel from the Seaboard Air Line Railroad bridge to the foot of Kings Island was completed in 1931; the rest, from the foot of Kings Island to the Atlantic Creosoting wharf, including the turning basin opposite the Savannah Sugar Refinery's wharf, in 1937. Crosstides channel was closed with a hydraulic fill in 1937. The anchorage basin and mooring dolphins near Fort Oglethorpe were completed in 1926; of the 10 dolphins originally constructed, all have been destroyed. The channel enlargements at Drakies Cut, Kings Island, and at West Broad and Barnard Streets, were completed in 1931, 1929, and 1924, respectively. Whitehall chan- nel training wall was completed in 1929 and was replaced by three spur dikes in 1937; these spur dikes are in good condition. Fig Island training wall was raised and extended in 1940 and is in good condition. Long Island training wall hydraulic fill was ,com- pleted in 1931 and other training walls and jetties prior to 1929, and are in fair condition. The work remaining to complete the proj- ect consists of construction of bank protection and extension of permeable dikes in the upper reaches of the harbor and deepening the channel to 34 feet and 400 feet wide from the presently authorized 34-foot channel to a point above the Georgia Ports Authority terminal with a turning basin at upper end. In June 1957, least depths in midchannel for half-project width at mean low water were 34 feet from the sea to Blinker 24 (in the vicinity of Fort Pulaski); thence 28 feet to the Mexican Petroleum Corp.; thence varying from 28 feet to 12 feet at the extreme upper limits of the harbor. The turning basins had the following controlling depths: Kings Island Turning Basin, 34 feet; Whitehall Turning Basin, 30 feet; Port Wentworth Turning Basin, 19 feet in the lower half and 13 feet in the upper half. The costs under the existing project to June 30, 1957, have been $8,699,475 for new work and $27,109,265 for maintenance, a total of $35,808,740.

SAVANNAH RIVER BELOW AUGUSTA, GA. Location. This river is formed by the confluence of the Tugaloo and Seneca Rivers on the northwestern part of the South Carolina- Georgia boundary line. It flows southeast 314 miles, forming the boundary line, and empties into the Atlantic Ocean 16.6 miles below Savannah, Ga. (See U. S. Geological Survey maps of South Carolina and Georgia.) Previous project. Adopted by the River and Harbor Act of March 3, 1881. A subdivision between new work and maintenance is not possible. For further details see page 1813, Annual Report for 1915 and page 581, Annual Report for 1938. Existing project. Provides for a channel 9 feet deep and 90 feet wide (at ordinary summer flow, which corresponds to a discharge of 5,300 second-feet at Augusta, Ga., with the Clark Hill powerplant in operation), from the upper end of Savannah Harbor to the head of navigation at Augusta, 3 miles above Fifth Street Bridge, about 199 miles. The improvement is to be ob- tained by construction of one lock and dam at New Savannah Bluff, use of contraction works, closure of cutoffs, bank protection, dredging, removal of snags, overhanging trees and wrecks, and open-river regulation. The mean tidal variation at the mouth of the river is 7.1 feet. The freshet variation above the normal pool level (elevation 114.5 mean sea level) of the New Savannah Bluff lock and dam at the head of the improvement is ordinarily about 13 feet with an extreme of 34 feet.

ARMY, 1957 The estimate of cost of new work, revised in 1956, is $6,982,000, exclusive of amount expended on previous projects. The average annual maintenance cost during the past 5 years was $77,096, of which $28,114 was for operating and care. Local cooperation. The project provides that local interests furnish, without cost to the United States, all necessary rights-of- way and spoil-disposal areas for the new work and subsequent maintenance, when and as required; hold and save the United States free from any damage resulting from construction and maintenance of the improvement; and provide and maintain ade- quate terminal and transfer facilities, including a suitable public terminal at Augusta, Ga., open to all on equal terms. The city of Augusta has agreed to act as local assurer for the project in accordance with a resolution passed by the City Council of Augusta on May 6, 1957. Terminal facilities. The only water terminals served by this improvement are at Augusta and at or near Savannah. The city of Augusta owns and operates, on equal terms to all, a wharf and warehouse; a short distance below this terminal the Pure Oil Co. has a terminal (storage capacity of 27,500 barrels) for berthing and discharging oil barges; The Texas Co. has under construction a terminal for berthing and discharging oil barges; and just outside the eastern city limits is the Merry Brothers Brick and Tile Co.'s terminal. This company also has terminal facilities at Savannah. At Savannah there is one municipal wharf and a State dock suitable for berths for river steamers, open to the public on equal terms. In addition, there are extensive facilities at Savannah, privately owned, for oceangoing and smaller vessels. Along the river there are numerous natural landings without wharves or railway connections. The terminal facilities are considered ample for existing commerce. Operations and results during fiscal year. New work: Ad- vance engineering and design to provide a 9-foot channel from Savannah to Augusta was initiated. The cost was $52,203. Maintenance: Construction of pile dikes, by contract, at miles 197 and 199 was initiated. The cost was $53,681. The U. S. nonpropelled crane barge No. 1 with towboat Piasi did mainte- nance snagging during the period February 4 to June 30, 1957, removing 4,160 snags between mile 32 and mile 43 and mile 92 and mile 203. The cost for snagging was $25,902. Condition surveys, supervision and administration by Government plant and hired labor cost $3,258. The minimum daily flow of the river at New Savannah Bluff lock and dam during fiscal year 1957 was 5,300 cubic feet per second. Minimum weekly flow was 5,300 cubic feet per second. The minimum daily and weekly flows of record prior to 1957 were 1,105 and 1,220 cubic feet per second, respectively. Powerplants with storage on the river are Clark Hill Dam, a Federal multipurpose project 22 miles above Augusta; the Stevens Creek Plant, 9 miles above Augusta; and the 6 plants of the Georgia Power Company on the headwaters. From the time that filling of the Clark Hill Reservoir was begun in December 1951 RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 447 until the second generating unit was placed in operation in February 1953, a flow of about 3,000 cubic feet per second or better was maintained 95 percent of the time. Since that time the flow releases from Clark Hill have been those resulting from the operation of the project in the interest of flood control, navigation and hydroelectric power, which provides a minimum flow of 5,300 cubic feet per second at the Butler Creek gage for navigation. The severe drought during 1954 and 1955 necessi- tated reducing the flow below 5,300 second feet. Maintenance (operating and care) : The lock and dam at New Savannah Bluff was operated, and ordinary repairs and improve- ments were made to the structure and appurtenant works, at a cost of $29,116. The total cost of work from regular funds was $111,957, of which $82,841 was for maintenance and $29,116 for operating and care. Condition at end of fiscal year. The existing project was about 40 percent completed. The lock and dam at New Savannah Bluff was completed in 1937 and is in good repair. In general, the open- channel works are in fair condition; a few of the structures are in need of repairs; however this work will be accomplished by the authorized modification to the existing project. The controlling depth was 6 feet or greater 100 percent of the fiscal year. This depth corresponds to a discharge of 5,300 second-feet at the Butler Creek gage. The work remaining to be done to complete the project is as follows: Deepen the channel to 9 feet and widen to 90 feet between the upper end of Savannah Harbor and the present head of navigation at Augusta, Ga.

No planning funds have been allotted for the other projects. Individual reports on the two reservoirs are given in the following pages. 7. HARTWELL RESERVOIR, SAVANNAH RIVER BASIN, GA. AND S. C. Location. The site of the Hartwell Dam is on the Savannah River 305 miles above its mouth and 89 miles upstream from Augusta, Ga. At full-power-pool elevation, the reservoir will ex- tend 7.1 miles up the Savannah River to the confluence of the Tugaloo and Seneca, 41 miles up the Tugaloo, 27 miles up the Seneca to the mouth of upstream Little River, S. C., thence 2 miles up Little River to the Newry site, and 7 miles up the Keowee to the Old Pickens site, and 8 miles up Deep Creek. (See U. S. Geological Survey maps of Georgia and South Carolina.) Existing project. The Flood Control Act approved May 17, 1950, authorized $50 million to be appropriated for constructing the Hartwell Reservoir in the general plan for the comprehensive development of the Savannah River Basin approved in the Flood 450 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Control Act of December 22, 1944, in addition to the authorization for project construction in the act of December 22, 1944, recom- mended in House Document 657, 78th Congress, 2d session. This project, as now planned, provides for a gravity-type concrete dam 1,948 feet long with earth embankments at either end, 9,621 feet long on the Georgia side and 6,366 feet long on the South Carolina side. The total length of the dam will be about 17,935 feet. The main dam will consist of two nonoverflow concrete sections, 540 feet long on the Georgia side and 444 feet long on the South Carolina side, a gravity-type concrete spillway 568 feet long equipped with 12 tainter gates 40 by 35 feet, in the channel, and an intake section 340 feet long with the powerhouse on the Georgia side of the river. The maximum height of the concrete section will be 204 feet above river bottom and the earthfill embankments will vary in height to a maximum of about 106 feet. At full- power-pool elevation 660 the reservoir will provide a total storage of 2,562,600 acre-feet of which 1,427,600 acre-feet will be usable. The initial power installation will be 198,000 kilowatts, and the ultimate will be 330,000 kilowatts. The estimated cost, revised in 1956, is $67,588,000 for construc- tion, $10,495,000 for lands, and $16,217,000 for relocations and rights-of-way, a total of $94,300,000. Local cooperation. None required. Operations and results during fiscal year. A restudy of the entire Hartwell project was initiated in January as a result of questions raised by the Clemson College Board of Trustees and the South Carolina Congressional delegation. The restudy is for the general purpose of reevaluating and reinvestigating the feasi- bility of the present project plan as well as alternate plans includ- ing lower power-pool elevations. Because of this issue, work on detailed planning has been limited and construction contracts were let only during the first six months of the year. Work was continued under existing contracts and acquisition of land was continued with 10,200 acres being acquired in fee simple during the year. The cost during the fiscal year was $3,244,626, all for new work. Condition at end of fiscal year. Construction of the project, commenced October 24, 1955, was about 7 percent completed. The Hartwell restudy was about 90 percent completed. The status of work on major construction contracts initiated to date is as follows: Percent complete Relocation of Twelve Mile Creek portion of State Route 133..................... 100 Earth embankments (phase I) --------------------------------------------------- 100 U.S. 29 Roadway --------------------------------------------------------------- 100 U.S. 29 Bridge ----------------------------------------------------------------- 22 Ga.

CLARK HILL RESERVOIR, SAVANNAH RIVER BASIN, GA. AND S. C. Location. The work covered by this project is a dam and reser- voir on the Savannah River and its tributaries in Georgia and South Carolina. (See U. S. Geological Survey maps of Georgia and South Carolina.) Existing project. The Flood Control Act approved December 22, 1944, approved the general plan for the comprehensive develop- ment of the Savannah River basin for flood control and other pur- poses as recommended in House Document 657, 78th Congress, 2d session, and authorized the construction of the Clark Hill Reservoir on the Savannah River in Georgia and South Carolina at an esti- mated cost, revised in 1956, of $78,540,000. The latest (1956) approved estimate for annual cost of maintenance and operation is $534,000. The Clark Hill Reservoir is on the Savannah River, Ga., and S. C., about 22 miles upstream from Augusta, Ga. The dam is 5,680 feet long, consisting of a concrete section 2,282 feet long with a maximum height of 200 feet, and a controlled-spillway section 1,096 feet long. The concrete section is flanked on the west by a rolled-earth embankment extending 2,069 feet to the abutment, and on the east by a similar embankment 1,329 feet long. The reservoir has a total storage capacity of 2,900,000 acre-feet, of which 390,000 acre-feet is reserved for flood control and 1,340,000 acre-feet is used for the storage of water for generating hydro- electric power. The power installations consist of 7 generating units of 40,000 kilowatts each, a total of 280,000 kilowatts. Local cooperation. None required. Operations and results during fiscal year. All lands have been procured but final settlement is incomplete pending court action on several tracts. Switchboard equipment has been installed in connection with additional transmission lines extended into the 452 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 area by Georgia Power Co. The centralized, automatic control system in the powerhouse was completed. Animated display of power plant and audio-visual equipment were installed. Road to shop and storage buildings in the service area was completed. A remodeled building was provided for the display of scientific in- formation and historical relics. The cost during the fiscal year was $153,448, all for new work. Operation and maintenance. Operation and ordinary mainte- nance of the dam, powerhouse, reservoir, service and recreation facilities, including rehabilitation, and supervision and administra- tion incidental thereto cost $448,867. The total cost during the year was $602,315, of which $153,448 was for new work and $448,867 was for operation and mainte- nance. Condition at end of fiscal year. Major construction items were completed. Work remaining to be done involves real estate de- ficiency judgments and construction of additional recreational facilities. The project, commenced in November 1945, and completed in July 1954, was in operation. The costs under the existing project to June 30, 1957, have been $78,609,661 for new work and $1,641,357 for operation and maintenance, a total of $80,251,018.

This section includes that part of the Intracoastal Waterway between the southerly limit of Fernandina Harbor, Fla., at the junction of Lanceford Creek and Amelia River, and the St. Johns River, Fla. (See U. S. Coast and Geodetic Survey Chart No. 577.) (For Beaufort, S. C., to Cumberland Sound section, see p. ?) Previous projects. The first project for the improvement of that part of the waterway was authorized by the River and Harbor Act of May 23, 1828, and modified by River and Harbor Act of June 23, 1874. For further details see Annual Report for 1915, page 1823, and Annual Report for 1938, page 605. Existing project. This provides for dredging and maintaining a channel 12 feet deep, with widths of 90 feet in land cuts and narrow streams and 150 feet in open waters, following in general the alinement of the existing waterway from Fernandina Harbor to St. Johns River, about 21.9 miles, with a cutoff in Kingsley Creek just north of the Seaboard Air Line Railroad bridge, and with such additional cutoffs or other changes in the adopted route as may be found desirable and justified by the resultant benefits to navigation. The mean range of tide is 6.1 feet at Fernandina 455 456 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 and 3.8 feet in the St. Johns River, with fluctuations from 1.5 to 3 feet, due to winds and lunar phases. The actual cost of new work was $263,659, excluding amounts expended under previous projects. The average annual mainte- nance cost during the past 5 years was $17,637. The existing project was authorized by the following: Acts Work authorized Documents Mar. 4, 1913 For a channel 100 feet wide and 7 feet deep_--------- H. Doc. 898, 62d Cong., 2d sess.

Maintenance: Con- tract pipeline dredge Ideal removed 23,246 cubic yards of material from the waterway to restore project depth over shoals at Sawpit Bluff and north end of Sawpit Creek Cutoff April 16-25, 1957, at a cost of $23,113. Hired labor surveys and reports during the year cost $8. The total costs for the fiscal year were $23,121 for maintenance. Condition at end of fiscal year. A 7-foot channel, dredged be- tween October 1913 and February 1915, was deepened to 12 feet with present authorized widths between November 1940 and Sep- tember 1941, thereby completing the existing project. The length of the waterway was reduced 2.4 miles between May and October 1943 by making five cutoffs and widening bends at three localities. To safeguard navigation through bridge openings and to permit breaking tows when tidal conditions are adverse, 14 protective and 10 tieup dolphins have been constructed at the Sisters Creek bridge at the southerly entrance to the waterway, and 8 protective and 10 tieup dolphins have been constructed at the Kingsley Creek bridges, about 4 miles south of Fernandina. At the Kingsley Creek bridges, three of the four center protective dolphins, one on the north side and two on the south side, have been destroyed.

The St. Johns River rises in the marshes of Brevard County, Fla., near the east coast, and flows northwesterly to Jacksonville, thence easterly into the Atlantic Ocean, 122 miles south of Savannah River. Its total length is about 285 miles. (See U. S. Coast and Geodetic Survey Chart No. 577.) Previous projects. Six appropriations for surveys and experi- mental dredging on the bar were made from 1852 to 1878. Proj- ects for permanent improvement were adopted by the River and Harbor Acts of June 14, 1880, and June 3, 1896. For further details see page 1823, Annual Report for 1915, and page 607, Annual Report for 1938. Existing project. This provides for: (a) A channel 34 feet deep from the ocean to Commodore Point via a cutoff channel from St. Johns Bluff (Fulton) to Dame Point and via Terminal Channel along the west bank of the river to Commodore Point, and thence 30 feet to the Florida East Coast Railway bridge at Jacksonville, with widths of 800 feet at the entrance and between the jetties, from 900 to 1,200 feet in Pilot Town Cut, from 1,050 to 1,335 feet in Mayport Cut, generally 500 feet in the St. Johns Bluff-Dame Point Cutoff, 1,200 feet at Dame Point, 590 feet in Terminal Channel (with the westerly edge 60 feet from the new pierhead-bulkhead line), from 400 to 900 feet in other cuts, in- creasing to as much as 1,115 feet at bends, and 300 feet in Arlington Cut, which is 30 feet deep and generally parallel to Terminal Channel; (b) a depth of 24 feet between that depth contour and the pierhead line at Jacksonville from Hogan Creek to the foot of Laura Street; (c) a depth of 28 feet to within 60 feet of the pierhead line in the area between the foot of Laura Street and the St. Elmo W. Acosta Bridge (formerly Duval County highway bridge) ; (d) a navigation and floodway channel 26 feet deep and 200 feet wide along the south side of the Com- modore Point terminals, terminating in deep water at each end; and (e) construction of training walls and revetments. All depths are referred to local mean low water. No dredging is to be done within 60 feet of a pierhead line. Natural depths of 34 feet or more, for adequate width, exist in midchannel from Commodore Point to the Florida East Coast Railway bridge at Jacksonville. Two converging rubblestone jetties, built at the entrance under a previous project, are maintained under the existing project. The north jetty is 14,300 feet long, and the south jetty is 11,183 feet long. The jetties are parallel and 1,600 feet apart for 4,022 feet from the sea ends. Stone retaining walls have been built at 7 localities, involving about 7 miles of this class of structure. 458 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Stone revetments at 5 localities provide about 3.7 miles of shore protection. The training walls and revetments are located be- tween Dame Point and Wards Bank, near the inner ends of the jetties. About 4 miles of these structures are located along the shores of the old channel which has now been replaced by the Dame Point-Fulton Cutoff. The length of section included in the project is 26.1 miles via the cutoff channel. The mean tidal range is 5.3 feet on the bar, 4.9 feet at Mayport, 2.6 feet at Dame Point (12 miles above the entrance), and 1.1 feet at Jacksonville (St. Elmo W. Acosta Bridge). The extreme range varies from about 9 feet on the bar to about 1.5 feet at Jacksonville. Strong northeasterly winds raise the water level about 2 feet at Mayport and Jacksonville. Strong southwesterly winds lower the water about 1.5 feet at Mayport and 1 foot at Jacksonville. The estimate of cost for new work (July 1956), is $12,750,000, exclusive of the amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $165,191.

RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 459 project is considered to be inactive and is excluded from the fore- going cost estimate. The cost of this portion was last revised in 1953, and was estimated to be $75,000. Local cooperation. All work authorized by the River and Har- bor Act of March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, and rights-of-way and spoil-disposal areas for the initial work and for subsequent maintenance when and as re- quired, and hold and save the United States free from claims for damages resulting from the improvement. It is provided that these requirements as to the 28-foot depths dredging between the foot of Laura Street and the St. Elmo W. Acosta Bridge may be waived or modified if in the discretion of the Chief of Engineers such action is necessary in the interest of national defense (H. Doc. 322, 77th Cong., 1st sess.). The deepening of the improve- ment to 34 feet is subject to the additional requirement (S. Doc. 230, 78th Cong., 2d sess.) that local interests give assurances satisfactory to the Secretary of War that they will modify ter- minal facilities as necessary to permit full utilization of the deeper channel. A resolution adopted January 4, 1946, by the Jackson- ville Chamber of Commerce, agreeing to comply with the above- mentioned features of local cooperation, was accepted by the Secretary of War on February 11, 1946, as satisfactory assurance of compliance. All spoil-disposal areas and rights-of-way re- quired in connection with the new-work dredging between Com- modore Point and the ocean and for the cutoff channel have been furnished. Terminal facilities. There are 77 piers and wharves serving the waterborne commerce of the port. The depths of water vary from 34 feet at the larger terminals to a few feet at the inner end of the slips and at the barge berths. The Jacksonville municipal terminals at Talleyrand Avenue consist of three piers; depth at these piers is maintained at 30 feet mean low water. There are 30 other piers and wharves used for handling water- borne commerce of the port or mooring vessels, 10 of which are open to the public. All have railway and highway connections except 7 of the smaller piers, which have highway connections only. Of the remaining piers, 26 are used in connection with shipyards and marine repair plants, 2 for recreational craft, 8 for industrial purposes, and 2 are not used. A large waterfront parking area was constructed by the City of Jacksonville which replaced 8 piers, and 3 new piers were constructed, 1 by the Navy' Department and 2 by oil companies. In addition, privately operated piers and wharves are available at Mayport, Fla., to serve the fishing industry, and facilities for serving recreational craft are available at Fulton. The facilities are considered adequate for existing commerce. (See Port Series No. 15, revised 1947, Corps of Engineers.) Operationsand results during fiscal year. Maintenance: Dredg- ing, under continuing contract, to restore project dimensions in the 460 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 ship channel, which was begun March 9, 1956, and 79 percent com- pleted at beginning of fiscal year, was completed August 3, 1956. Contract dredge Congaree removed 150,901 cubic yards of material at a cost of $54,089. Extension to St. Johns Bluff training wall was completed by contract April 16-26, 1957 at a cost of $14,722. Hired labor surveys, inspections, and reports cost $2,854. The total cost for the fiscal year was $71,665 for maintenance. Condition at end of fiscal year. The existing project was about 97 percent completed. Dredging was begun about November 1910. A channel at least 30 feet deep and of practicable width from the entrance to Jacksonville was completed in March 1922. Widening the 30-foot channel to authorized widths was completed in July 1937, except Terminal Channel, which was only 400 feet wide. Deepening the existing channels to 34 feet including widen- ing Terminal Channel to 575 feet was begun in July 1947, and was completed in December 1951. The Dame Point-Fulton Cutoff was opened to traffic in June 1951. The easterly end of Bar Cut was dredged to depths of 40 and 42 feet and 700 feet wide between April and September 1951. Those depths were obtained to accom- modate United States Navy aircraft carriers at no cost to the project. A depth of 24 feet was provided between the 24-foot contour and the pierhead line at Jacksonville, from Hogan Creek to the Florida East Coast Railway bridge, between October 1907 and January 1912. The two jetties at the entrance, constructed between December 1880 and June 1904, under a previous project, have been maintained under the existing project. About 3,555 linear feet of the inner end of the north jetty has been capped with concrete. All training walls and revetments considered necessary on 30-foot project were constructed between July 1892 and May 1894, by Duval County, and by the United States, under the former existing project, intermittently between October 1903 and September 1927. The easterly end of Wards Bank training wall has been revetted with granite riprap. Material dredged near the westerly end of Bar Cut and deposited along the north side of the north jetty near the Fort George River encroachment has effectively prevented further erosion adjacent to that struc- ture. The jetties are in fair condition except as follows: South jetty: Capstone has been displaced in isolated locations and at the outer 800 feet. North Jetty: The north shoreline has receded about 1,400 feet leaving the jetty exposed. Capstone has been displaced in the outer 300-foot section and in the 1,300-foot section seaward of the monolithic cap. The monolithic cap has been broken and concrete washed away in two locations, one 50 feet long and the other 20 feet along, near the middle of the section. Revetments and training walls: Ward Bank training wall, having been reinforced with heavy capstone at the easterly end by the Navy Department, is in good condition. The 800-foot westerly extension, a Wakefield-pile wall, has been replaced by a rubble concrete revetment by the Navy Department. Mile Point training wall is in fair condition. The adjacent shore at the east end is eroding. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 461 White Shells training wall has been repaired and is in good condition. St. Johns Bluff training wall has been extended up- stream approximately 300 feet to prevent some of the erosion occurring near Fulton, Fla. Fulton training walls are in good condition; however, due to Dame Point-Fulton Cutoff they are no longer in the proper location to prevent the erosion now occurring in the vicinity of Fulton, Fla. Dame Point training wall is in poor condition and should be repaired and extended eastward along both north and south banks to prevent continued erosion. Bank erosion, apparently resulting from recent new-work dredg- ing operations, is visible at several locations; remedial measures may be required. These areas are: (a) North bank of river from Haulover Creek, (Pilot Town) to the north jetty; (b) south bank east of Mile Point training wall; (c) south bank from Intracoastal Waterway to White Shells Point; (d) south bank at Dame Point- Fulton Cutoff; (e) north and south banks along upper one-fourth of Dame Point-Fulton Cutoff; and (f) north bank from Dame Point to Dunns Creek. The Matthews Bridge (fixed) crosses the river at mile 22.3. Vertical clearance over the Terminal Channel is 148.3 feet and over Arlington Cut, 86.8 feet. A survey in July 1955 gave evidence of shoaling in most of the cuts. Controlling depths in the more affected areas are 28.8 feet in St. Johns Bar Cut Range-West Section, 26.0 feet in Quarantine Island Upper Range, and 29.5 feet in Broward Point Turn. The limiting depth in the left outside quarter of Terminal Channel was 29.3 feet; left inside quarter, 32.5 feet; right inside quarter 33.4 feet; and right outside quarter 33.2 feet. A controlling depth of 24 feet was available to the pierhead line between Hogan Creek and the foot of Laura Street in 1934 and to within 60 feet of the pierhead line, thence to the St. Elmo W. Acosta Bridge in 1938. The work remaining to complete the project is to dredge the area between the foot of Laura Street and St. Elmo W. Acosta Bridge to a depth of 28 feet, and the navigation and floodway channel along the south side of Commodore Point terminals.

This provides for a channel 13 feet deep and 200 feet wide from the Florida East Coast Railway bridge at Jacksonville to Palatka (54.5 miles), thence 12 feet deep and 100 feet wide to Sanford (86.1 miles), with a side channel of like dimensions to Enterprise and with cutoffs and easing of bends, and thence 5 feet deep and 100 feet wide to Lake Harney (20.9 miles), with a cutoff channel 5 feet deep and 75 feet wide between Lake Monroe and the vicinity of Osteen Bridge; and for a channel 8 feet deep, 100 feet wide across the bar at the mouth of Deep Creek, and thence 50 feet wide to Hastings Landing, 5 miles above the mouth. The plane of reference is local mean low water. The length of the project is 161.5 miles in the St. Johns River, 5 miles in Deep Creek, 2.7 miles in the approach channel to Enterprise, and 0.9 mile in the alternative approach channel to Sanford. Two pile-and-stone jetties at Volusia Bar at the head of Lake George, built under a previous project, are maintained under the existing project. The jetties are 3,400 and 2,200 feet long, respectively. The mean tidal range is 1.1 feet at Jacksonville and 1.2 feet at Palatka. At low water stages, tidal influence is perceptible at Sanford, 140.6 miles above Jacksonville, and upstream currents are sometimes noticeable as far as Lake Harney. The extreme tidal range is about 1.5 feet at Jacksonville and 2 feet at Palatka. Brisk northerly and northeasterly winds raise the water level about 2 feet at Jacksonville and 1 foot between Palatka and San- ford. Brisk southerly and southwesterly winds lower it about 1 foot between Jacksonville and Sanford. Flood stages in the river usually occur during the fall; and the usual maximum is about 2 RIVERS AND HARBORS--JACKSONVILLE, FLA., DISTRICT 463 feet at Palatka, 3 feet at Lake George, 8 feet at Sanford, and 9 feet at Lake Harney. The actual cost of new work was $1,141,677. The average annual maintenance cost during the past 5 years was $22,135. Two portions of the project, which are considered to be inactive and are excluded from the project are (1) improvement of Deep Creek, as authorized by the River and Harbor Act approved March 2, 1919 (H. Doc. 699, 63d Cong., 2d sess.) providing for a channel 8 feet deep and 50 to 100 feet wide up the creek to near Hastings, Fla., and (2) Beresford Cutoff in the Palatka to Lake Harney section, as authorized by the River and Harbor Act ap- proved July 24, 1946 (S. Doc. 208, 79th Cong., 2d sess.), providing for a 1/2 -mile-long cutoff 12 feet deep, 100 feet wide across Beres- ford Peninsula from Lambs Bluff to Lake Beresford. The costs of these portions were last revised in 1953, and were estimated to be $44,400 for Deep Creek and $108,000 for Beresford cutoff, a total of $152,400.

All requirements prior to those imposed by the River and Harbor Act approved March 2, 1945, have been fully complied with. The requirements imposed by that act and the River and Harbor Act approved July 24, 1946, have been fully complied with as regards new work except for furnishing rights- of-way and spoil-disposal areas for Beresford Cutoff, which is not to be provided at this time. Those acts imposed the requirement, among others, that local interests furnish, free of cost to the United States, suitable spoil-disposal areas for subsequent mainte- nance. The Woodruff Creek cutoff (H. Doc. 445, 78th Cong., 2d sess.) is subject to the additional requirement that local interests 464 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 agree to hold and save the United States free from any damages resulting from this work. Deepening to 12 feet between Palatka and Sanford and in the branch to Enterprise (S. Doc. 208, 79th Cong., 2d sess.) is subject to the additional requirement that re- sponsible local interests will give assurances satisfactory to the Secretary of War that they will provide and maintain, without cost to the United States, adequate terminal facilities, when and as required, which shall be open to all on equal terms. A resolution adopted July 5, 1945, by the Board of County Commissioners for Seminole County, agreeing to comply with the conditions imposed by House Document 445, 78th Congress, 2d session, was accepted by the Secretary of War on October 3, 1945, as satisfactory assurances of compliance. Local interests at San- ford have indicated that they will construct additional facilities when and as required by the traffic on the waterway. The present facilities are considered adequate for the existing commerce. Terminal facilities. There are ample wharves and terminals at Jacksonville and about 24 piers and wharves at various points on the river above Jacksonville. These include the following: Municipal piers or wharves at Mandarin, Green Cove Springs, Federal Point, and Palatka; a municipal recreational pier at San- ford; and 6 privately owned piers at Palatka, five at Sanford, and eight at other points along the river between Palatka and Sanford. Five of the private piers have nearby tank storage for petroleum products as follows: One at Palatka, one at Lake Monroe, one at Enterprise, and two at Sanford. All piers have highway connec- tions and one at Palatka has railway connections. In addition, there are a number of small, privately owned piers and wharves for recreational craft at various points along the river. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: The contract pipeline dredge Ideal removed 179,039 cubic yards of material in the reach between Astor and Sanford and Enterprise May 7-29, 1957, at a cost of $109,068. Hired labor surveys, inspections, and reports cost $12. The total cost for the fiscal year was $109,080 for maintenance. Condition at end of fiscal year. The existing project is com- plete. Dredging between Jacksonville and Palatka was begun in April 1900 and completed in November 1915. In 1939, the Department of the Navy deepened the channel between Jackson- ville and the United States Naval Air Station at Black Point to 18 feet. A channel 8 feet deep and 100 feet wide from Palatka to Sanford, including side channel to Enterprise, was dredged be- tween February 1911 and June 1923, except for making three cutoffs and easing a number of bends, which were completed in June 1935. Deepening that channel to 12 feet, including the side channel to Enterprise and easing a number of bends was begun in August 1947 and completed in October 1948. A channel 5 feet deep and 100 feet wide from Sanford to Lake Harney was dredged between November 1911 and March 1912, and the Woodruff Creek cutoff channel, 5 feet deep and 75 feet wide was dredged during RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 465 February and March 1948. Two converging pile-and-stone jetties at Volusia Bar at the head of Lake George, built under a previous project between December 1880 and May 1887, have been maintained under the existing project. When last surveyed, controlling depths were as follows: Jack- sonville to the United States Naval Air Station, 18 feet for project width in 1939; thence to Palatka, 9.7 feet in the middle 100-foot width of channel at Federal Point, with 11.2 feet available in the easterly half of the channel, in October 1945; from Palatka to Sanford, 12 feet, based on surveys in February 1956; Enterprise side channel, 12 feet in May 1957; and Sanford to Lake Harney, 7 feet in Woodruff Creek Cutoff and 4.2 feet in midchannel elsewhere, with a limiting edge depth of 2.5 feet, April 1949. The total costs under the existing project to June 30, 1957, have been $1,141,677 for new work and $542,755 for maintenance, a total of $1,684,432.

OKLAWAHA RIVER, FLA. Location. This river has its source in the system of large lakes in the central part of the Florida peninsula and flows generally northerly, then easterly, emptying into the St. Johns River, 22 miles above Palatka. The extreme head of the system may be taken as Lake Apopka, 120 miles above the mouth of the river. Previous projects. The first improvement was authorized by an act of Congress approved February 24, 1835. For further details see page 1825, Annual Report for 1915, and page 613, Annual Report for 1938. Existing project. This provides for clearing the river of ob- structions from the mouth to Leesburg, including the Kyle and Young Canal and its extension to Morrisons Landing and the J. D. Young Canal from Morrisons Landing to Starks Ferry (clear title to the canals and sufficient land adjacent thereto to provide for future widening has been conveyed to the United States), and for maintaining the dikes with a view to obtaining a navigable depth of about 4 feet to 'Leesburg, 85.7 miles above the mouth. The work embraces dredging, snagging, removing overhanging trees and obstructive aquatic vegetation, and constructing a lock and dam at Moss Bluff to maintain the water level in Lake Griffin. 466 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The project includes, under maintenance, the operation and care of that lock and dam. Lock and dam at Moss Bluf Distance to nearest town_ 20.2 miles by canals.

The river is nontidal except for a short distance above the mouth at the St. Johns River, where the mean range at low-water stage is about 0.5 foot. The mean fluctuation due to rainfall is about 2 feet at the mouth, about 3 feet at the mouth of Silver Springs Run, and about 2.5 feet at Lake Griffin. The extreme fluctuation is about 3 feet at the mouth, 5 feet at Silver Springs Run and about 4.5 feet at Lake Griffin. The actual cost of new work was $315,264. The average annual maintenance cost during the past 5 years was $28,564. The por- tion of the project authorized by River and Harbor Act approved March 2, 1907 (H. Doc. 782, 59th Cong., 1st sess.), providing for a 6-foot depth channel to the head of Silver Springs Run is con- sidered to be inactive and is excluded from the project.

Numerous private and public landings and boatlaunching ramps are along the river. A public recreation- craft basin and boatlaunching ramps owned by the county, are RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 467 located near Silver Springs, Ocala, Fla., and a municipal wharf is located at Leesburg. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance. The lock and dam were operated and maintained, and the buildings and grounds were maintained by hired labor, at a cost of $11,826. Minor rehabilitations cost $28. The costs for the fiscal year were $28 for maintenance and $11,826 for operations and care, a total of $11,854. Condition at end of fiscal year. The existing project was com- plete. By dredging, making cutoffs, and snagging intermittently between January 1892, and June 1914, a clear channel with a depth of about 6 feet at ordinary stages was obtained to a point about 32 miles above the mouth. A channel 4 feet deep at mean low water and 30 feet wide between Silver Springs Run and Moss Bluff lock was dredged between late 1924 and November 1929. A lock and dam at Moss Bluff were constructed between about March 1923 and late 1925. For further details relative to this lock see paragraph "Existing project." The United States reser- vation comprises 13 acres of land, 2 dwellings, a storehouse, and other small buildings. Most of the original dredging of the canal between Heather Island (6.3 miles above the mouth of Silver Springs Run) and Starkes Ferry near Lake Griffin was done by private interests between 1911 and 1923. Between June 1929 and June 1930, the canal between Moss Bluff lock and Starkes Ferry was enlarged to 8 feet deep by 50 feet wide to provide for control of Lake Griffin. The dike on the east side of the canal was re- paired and improved as a maintenance feature from June to December 1936. The river was cleared of obstructions between October 1955 and May 1956. The dike between Moss Bluff lock and dam and Starkes Ferry was repaired and graded between March and April 1956. The lock was placed in good condition between March and June 1956. High waters from abnormal discharge during 1954 developed weak points in the dike below the dam. The controlling depths at normal stages were approximately as follows: Mouth of the river to Silver Springs Run, 3.5 feet; Silver Springs Run to Moss Bluff lock, 1.0 feet; and Moss Bluff lock to Leesburg, 5.0 feet.

In addition, $11,415 was expended between August 1, 1929, and June 30, 1935, on the operation and care of the works of the improvement under the provisions of the permanent indefinite appropriation for such purposes. 5. RICE CREEK, FLA. Location. Rice Creek rises in north-central Putnam County, Florida and flows easterly 10 miles through generally low, swampy, and densely forested areas to empty into St. Johns River about 3.5 miles north of Palatka and 43 miles south of Jackson- ville (see U. S. Coast and Geodetic Survey Chart No. 686). Existing project. This provides for a channel 12 feet deep and 100 feet wide from beacon 64 in the St. Johns River to the mouth of Rice Creek, and thence 75 feet wide to the access channel of the Hudson Pulp and Paper Corp. except through the rail- road and highway bridges, including a cutoff and suitable straightening, widening, and snagging. The mean tidal range is about 1.2 feet. The actual cost of new work was $170,415, including $85,207 contributed by local interests. No maintenance cost has been incurred since completion of the project in October 1956. The current annual maintenance estimate is $2,000. The existing project was authorized by the River and Harbor Act approved September 3, 1954 (H. Doc. 446, 82d Cong., 2d sess.). The latest published map is in the project document. Local cooperation. The act adopting the project imposed con- ditions that local interests (Hudson Pulp and Paper Corp.) contribute in cash 50 percent of the cost of constructing the chan- nel; furnish without cost to the United States all lands, easements, rights-of-way, and suitable spoil-disposal areas for initial con- struction, and subsequent maintenance when and as required; hold and save the United States free from damages due to construction and maintenance of the improvement; and maintain the access channel and turning basin at the paper mill to project depth. On February 24, 1956, the Chief of Engineers accepted as satis- factory the Hudson Pulp and Paper Corp. agreement to comply with the stated conditions with the exception that future main- tenance of the project channel will in each instance be subject to advance provision by the corporation of suitable spoil-disposal areas, and agreement by the corporation to hold and save the United States free from damages resulting from claims due to that particular maintenance operation. The Atlantic Coast Line Railroad widened the north half of its swing bridge to 40 feet under a Department of the Army permit, dated August 2, 1950. Between July 21 and August 13, 1952, while awaiting decision on its request for aid in clearing sunken logs and stumps from Rice Creek which were damaging oil barges delivering to its RIVERS AND HARBORS--JACKSONVILLE, FLA., DISTRICT 469 dock, the Hudson Pulp and Paper Corp. expended $1,558.81 in clearing the more prominent obstructions from the creek. Sub- sequently, the corporation contributed the balance of the required cash, or $1,806.68, for cooperative completion of the snagging and clearing of the creek by Government plant and hired labor be- tween February 9 and April 13, 1953. This work was accom- plished under authority of section 3 of the River and Harbor Act approved March 2, 1945. All rights-of-way and spoil-disposal areas and cash contribution required for the initial dredging of the project channel have been furnished. Terminal facilities. There are no public piers or wharves along Rice Creek, and there is no foreseeable need for any. A steel- sheet pile-and-timber bulkhead at the head of the Hudson Pulp and Paper Corp. turning basin and access channel affords about 300 feet of marginal berthing space. A mobile railroad crane is available for handling freight. Controlling depth at the bulkhead is about 10 feet. The basin has connections with U. S.17, Atlantic Coast Line Railroad, Georgia Southern and Florida Railway, and the Port of Jacksonville through Rice Creek and St. Johns River. The basin is open to all on equal terms and is adequate for present and prospective commerce. Ample space is available for future terminal expansion on Rice Creek and at the paper mill. Operations and results during fiscal year. New work: Con- tract dredge DeWitt Clinton began dredging operations August 26, 1956 and completed the 12-foot depth channel on October 3, 1956. Total material removed was 208,919 cubic yards at a cost of $163,785. Hired labor surveys, inspections, and reports cost $15. The total cost for the fiscal year was $163,800 ($81,672 Federal; $82,128 non-Federal) for new work.

INTRACOASTAL WATERWAY, JACKSONVILLE TO MIAMI, FLA. Location. The waterway extends from Jacksonville to Miami, Fla., following the St. Johns River to the mouth of Pablo Creek, 20 miles, and thence following in general the line of a canal con- structed by the Florida Coast Line Canal and Transportation Co. (See U. S. Coast and Geodetic Survey Charts Nos. 842-847.) Previous projects. Adopted by River and Harbor Acts of June 15, 1844, July 13, 1892, August 18, 1894, and Deficiency Act of February 26, 1896. For further details, see page 1825, An- nual Report for 1915; page 655, Annual Report for 1926; and page 618, Annual Report for 1938. Existing project. This provides for an inland waterway 12 feet deep at local mean low water and generally 125 feet wide from Jacksonville to Miami, with such modifications in cutoff and other questions of alinement as may be required by the Chief of Engineers; and for a basin 8 feet deep extending from the Intra- coastal Waterway to the easterly shore, about 1,140 feet wide at the waterway and 280 feet wide at the shoreline, at or near Vero Beach, Fla. The length of the waterway is 370 miles, of which 20 miles are included in the project for improvement of Jacksonville Harbor, Fla. The project also includes the operation and main- tenance of the Palm Valley highway bridge, the title to which was passed to the United States, along with all other property of the Florida Coast Line Canal and Transportation Co., under the conditions of local cooperation. The mean range of tide is 3.8 feet at the St. Johns River, 0.7 foot in the Indian River at Fort Pierce, 1.8 feet in Lake Worth at the Port of Palm Beach terminals, 2.3 feet at the Port Ever- glades terminals, and 2 feet in Biscayne Bay. The extreme range is about 7 feet at the St. Johns River, 1.5 feet at Fort Pierce, and 3 feet in Biscayne Bay. Tidal effect is imperceptible at points along the waterway distant from inlets.

RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 471 The estimate of cost for new work (July 1956) is $26,651,000, excluding amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $139,318. The Jacksonville Beach and Sebastian portions of the project are considered to be inactive and are excluded from the foregoing cost estimate. The Jacksonville Beach basin was essentially provided by local interests in dredging fill for highway at no cost to the United States. The cost of the Sebastian portion was last revised in 1953, and was estimated to be $35,700. Local cooperation. The conditions imposed by the River and Harbor Acts approved January 21, 1927, and July 3, 1930, have been fully complied with, including furnishing suitable spoil-dis- posal areas for subsequent maintenance of the improvement as and when required. Subsequent acts authorizing enlargement of the waterway have imposed the same requirement with respect to spoil-disposal areas for maintenance. The Florida Inland Naviga- tion District, a special taxing district empowered by State law to comply with certain features of local cooperation, was requested to furnish additional spoil-disposal areas in perpetuity for a 25- year maintenance program in the southerly and northerly halves of the waterway on May 15 and July 1, 1944, respectively. Numerous areas have been furnished and the navigation district is actively engaged in securing other areas by negotiation, or, when necessary, by condemnation. The areas are being fur- nished at a satisfactory rate. Temporary spoil-disposal areas for maintenance have been and are being furnished as and when required. All work authorized by the River and Harbor Act of March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, and rights-of- way and spoil-disposal areas for new work and for subsequent maintenance, when and as required, and hold and save the United States free from claims for damages resulting from the improvement. The act imposed additional requirements as fol- lows: (a) Deepening the waterway to 12 feet is subject to the conditions (H. Doc. 740, 79th Cong., 2d sess.) that local interests bear the cost of all alterations of bridges, cables, pipelines, and other structures made necessary by the improvement and that, if for any cause the Secretary of War finds it advisable, he may cause proceedings to be instituted in the name of the United States for acquirement by condemnation or otherwise of any lands, easements, rights-of-way, and spoil-disposal areas needed for the improvement, after receipt of assurances satisfactory to him from responsible local agencies that they will reimburse the United States for the costs; (b) provision of the basin at Vero Beach is subject to the requirements (H. Doc. 261, 76th Cong., 1st sess.) that local interests furnish assurances satisfactory to the Secretary of War that they will protect the shoreline with an adequate bulkhead, and provide, maintain, and operate terminals adequate for full utilization of the improvement, open to all on equal and reasonable terms. 472 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 A resolution adopted August 2, 1946, by the Florida Inland Navigation District was accepted by the Chief of Engineers December 24, 1946, as satisfactory assurance that the navigation district will furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas needed for new work and subsequent maintenance when and as required, and will hold and save the United States free from damages resulting from the construction and maintenance of the 12-foot project. The navigation district assumes no responsibility for the additional requirement that local interests bear the cost of all alterations of bridges, cables, pipelines, and other structures made necessary by the improvement (H. Doc. 740, 79th Cong., 2d sess.), as it is not empowered by State law to comply with such features of local cooperation. The bridges, cables, pipelines, and other structures are owned by various individuals and public and private corporations. Most of those structures were constructed under permits issued by or under authority of the Secretary of War. Alteration of all bridges, cables, pipelines, and other structures, made necessary by the improvement, can properly be required of the owners under existing Federal law. Procurement by the navigation district of the required rights-of-way and temporary spoil-disposal areas for new work is virtually complete for some sections of the waterway, and is well advanced and actively in progress in others. The navigation district states that it is in a position to furnish all remaining areas in a short time after it is evident that funds will become available. No delays due to lack of suitable rights-of-way and spoil-disposal areas, nor to alterations of bridges, cables, pipelines, and other structures made necessary by the improvement, are expected. On February 28, 1956, the City of Vero Beach stated that the resolution that it adopted August 8, 1945, agreeing to comply with the features of local cooperation pertaining to the basin at Vero Beach, which was accepted by the Secretary of War on November 28, 1945, as satisfactory assurances of compliance, remains effective. Terminal facilities. Extensive terminals with railway and street connections are available at Jacksonville and Miami. Terminals with railway and highway connections, for coastwise vessels have been constructed at Fort Pierce (Indian River), Riviera (Lake Worth), and Port Everglades Harbor. Municipal piers or wharves have been constructed at Titusville, Courtenay, Cocoa, Melbourne, and Vero Beach for handling general freight, and at St. Augustine, Daytona Beach, New Smyrna Beach, Eau Gallie, West Palm Beach, Delray Beach, Fort Lauderdale, and Miami for use by recreational craft. At Jacksonville Beach, Daytona Beach, Titusville, Eau Gallie, Fort Pierce, West Palm Beach, Fort Lauderdale, and Miami, yacht basins open to the public have been provided. They are connected with the Intra- costal Waterway by channels 6 to 8 feet deep and 80 to 100 feet wide. At Fort Pierce a channel 6 feet deep and 80 feet wide has been dredged by the United States from the Intracoastal RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 473 Waterway to and up Taylor Creek to the United States Coast Guard buoy depot. There are also a number of privately owned piers, wharves, and landings at various points along the water- way. The facilities are considered adequate for the existing commerce. (For further details on facilities at Jacksonville, Fort Pierce Harbor, Port of Palm Beach, Port Everglades, and Miami, see Port Series Nos. 15 and 16, revised 1947, and Port and Terminal Facilities Report, 1941, Corps of Engineers.) Operations and results during fiscal year. New work: Dredg- ing by continuing contract to enlarge the waterway to 12 by 125 feet between Eau Gallie and Wabasso and to provide the turning basin at Vero Beach was begun April 15, 1957. Pipeline dredge DeWitt Clinton removed 29,734 cubic yards of material, April 15-22. 1957, from Vero Beach Turning Basin at a cost of $41,312. The Clinton removed 275,443 cubic yards of material from the main channel, April 22-May 19, 1957, at a cost of $195,538. Maintenance: Dredging under contract to restore project dimen- sions in the waterway between St. Johns River and Melbourne, which was begun March 27, 1956 and 61 percent completed at be- ginning of fiscal year, was completed September 18, 1956. Pipeline dredge Ideal removed 177,702 cubic yards of material at a cost of $58,837. Dredging to restore an 8-foot depth between Melbourne and Miami, which was begun June 1, 1956 and 73 percent completed at beginning of fiscal year, was completed July 9, 1956. Contract pipeline dredge Two Brothers removed 9,903 cubic yards of mate- rial at a cost of $10,715. Under another contract, pipeline dredges Sandy and No. 2 removed about 61,500 cubic yards of material from shoaled areas in the same reach of the waterway between April 11 and June 30, 1957 at a cost of $49,439. Hired labor surveys, inspections, and reports cost $9,467. Operating and care: The steel and concrete double-leaf bascule highway bridge near Palm Valley was operated and maintained by hired labor throughout the fiscal year at a cost of $24,815. The total costs for the fiscal year were $236,850 for new work, $128,458 for maintenance, and $24,815 for operation and care, a total of $390,123 Condition at end of fiscal year. The existing project was about 43 percent completed. A channel 8 feet deep at local mean low water and 100 feet wide was dredged between March 1930 and May 1935. The northerly 171 miles section between the St. Johns River and Eau Gallie was enlarged to 12 by 125 feet between June 1951 and November 1953, except for a small plug, about 1 mile long, at Daytona Beach, which was removed year before last by the State Road Department. A steel and concrete, double-leaf bascule highway bridge near Palm Valley, to replace the temporary pontoon bridge at that locality, was constructed between September 1936 and July 1937, at a cost of $117,917. The existing channel widths are reduced at 55 localities by bridges, with a limiting horizontal clearance of 51 feet at the Deerfield Beach Bridge. 474 REPORT OF THE CHIEF OF ENGINEERS, U. S.

ST. AUGUSTINE HARBOR, FLA. Location. On the east coast of Florida, about 35 miles south of the entrance to St. Johns River and about 180 miles north RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 475 of Fort Pierce Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 1243 and 1244.) Previous projects. Appropriations were made by the acts ap- proved March 2, 1829, and June 27, 1834, for a survey of the harbor and the bar at the entrance. The River and Harbor Act approved August 11, 1888, authorized improvement of the harbor, subject to a subsequent report of a board of engineers. For further details see page 284, Annual Report for 1904, and page 623, Annual Report for 1938. Existing project. This provides for an entrance channel along the best natural alinement as it may exist from time to time, 200 feet wide and 16 feet deep at mean low water across the new inlet bar, thence 12 feet deep to the Intracoastal Waterway; for a sandtrap groin on the north side of the inlet and extending seaward from the ocean shore of Vilano Beach and a sandtight jetty on the south side of the inlet extending seaward from the ocean shore of Conch Island (formerly Vilano Point or North Point) parallel to and coextensive with the groin; and for a channel 10 feet deep and 100 feet wide in San Sebastian River from the Intracoastal Waterway to the King Street Bridge with a turn- ing place near the upper end. Those improvements are subject to such modification as in the discretion of the Secretary of the Army and Chief of Engineers may be advisable. The length of the inlet channel is about 1.5 miles, and the length of the San Sebastian River channel about 2.6 miles. The sandtrap groin now on the north side of the inlet is 1,580 feet long, with a 300-foot landward extension at an angle of 45 ° , constructed of granite, native rock, and creosoted timber. The south jetty, including a landward extension of revetment, is to be about 3,650 feet long. The mean tidal range is 4.5 feet in the ocean at St. Augustine Inlet (the old inlet) and 4.2 feet at the city waterfront. A 10-foot tide above mean low water was recorded at the water- front during a tropical storm in 1944 and again in 1950. The tidal range in San Sebastian River is about 4.5 feet; strong northerly winds, mostly in winter, lower the water surface about 1 foot. The estimate of cost of new work (July 1957) is $1,794,000 for the work at the new inlet and the channel in San Sebastian River, exclusive of amounts on previous projects but including $137,500 contributed by local interests. There is no current annual main- tenance estimate for the project as a whole; maintenance of San Sebastian River channel has been estimated at $3,600. The por- tion of the project of future landward extension of the groin is considered to be inactive and is excluded from the foregoing cost estimate. The cost of that portion was last revised in 1956, and was estimated at $605,000. Dredging of an entrance channel is now not necessary as a natural channel exists. The last estimate of cost was $35,000, in 1956. Extension to the south jetty has been made a part of the jetty construction in the form of revetment. 476 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The existing project was authorized by the following: Acts Work authorized Documents June 20, 1938 For a straight entrance channel 27 feet deep and 200 H.

Local cooperation. The work authorized by the River and Harbor Act of May 17, 1950, is subject to the condition that local interests furnish without cost to the United States all lands, easements, and rights-of-way necessary for construction and maintenance of the project, when and as required, and agree to hold and save the United States free from all claims for damages due to construction and maintenance of the works. The St. Augustine Port, Waterway and Beach District (Florida State Legislature empowered representative of local interests) adopted a resolution July 22, 1955, agreeing to comply with the local cooperation requirements. This assurance was accepted by the District Engineer August 3, 1955. All requirements have been met. Terminal facilities. There are 7 timber docks on the Matanzas waterfront of St. Augustine-the municipal yacht dock south of the highway bridge, 2 excursion boat docks, 2 private docks, and 2 motel docks. The principal terminals are the numerous shrimp docks in the San Sebastian River which flows southward through the city into the Matanzas River south of the bridge; these consist of timber wharves, with frame and corrugated-iron warehouses thereon, and 2 marine railways for small boats. The present terminals have highway connections and several of the shrimp docks have rail connections. They are considered adequate for existing commerce and recreational craft. Any extensive in- crease in commerce would require more suitable terminals. Operationsand results during fiscal year. New work. Contract pipeline dredge Overland, which began dredging April 27, 1956, on the 10- by 100-foot channel in San Sebastian River, completed the work July 1, 1956. The total yardage removed during the entire dredging operations was 101,870 cubic yards. The cost for the fiscal year was -$222. Construction of the south jetty by contract began January 15, 1957. The cost for the fiscal year was $543,098. The total costs for the fiscal year were $542,876 for new work. Condition at end of fiscal year. The existing project was about 64 percent completed. Between February and August 1941, a straight entrance channel 27 feet deep and 200 feet wide was dredged from the ocean across North Point (Vilano Beach) to RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 477 deep water in Tolomato River and a granite, native-rock, and creosoted-timber sand-trap groin, 1,580 feet long and extending from the coastline into the ocean, was constructed on the north side of the inlet. The channel rapidly shoaled, and maintenance of adequate depths along that alinement has been impracticable. To stop flanking caused by sea action at the shore end of the structure, the groin was extended 300 feet shoreward at an angle of 450, between September and December 1943. (The groin is in fair condition except for the seaward 300 feet which has subsided to about elevation 3.0 feet, mean low water.) In Sep- tember 1950, a depth of 9.8 feet was available in a marked, natural channel leading generally northeast from the inlet. The channel in San Sebastian River was completed and had project dimensions at the close of the fiscal year. The south jetty was 80 percent completed. The work remaining to be done is that of completing the south jetty. The costs under the existing project have been $1,015,376 for new work and $159,582 for maintenance, a total of $1,174,958. In addition, $137,500 were expended from contributed funds for new work.

FORT PIERCE HARBOR, FLA. Location. On the east coast of Florida, about 218 miles south of the entrance to St. Johns River and about 124 miles north of the entrance to Miami Harbor. (See U. S. Coast and Geodetic Survey Chart No. 582.) Existing project. This provides for the maintenance, enlarge- ment and deepening of the project developed by private interests, to provide a channel 350 feet wide at the 27-foot contour in the ocean, tapering to 200 feet wide at station 100+00 near the westerly side of the inlet, thence 200 feet wide across Indian River to station 30+00, and thence flaring on the southerly side to form a turning basin 1,650 feet long on the northerly side, 478 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 750 feet long on the southerly side, and 900 feet wide, the depth to be 25 feet in the basin and in the channel to station 130+00, and thence 27 feet to the 27-foot contour in the ocean; and for maintenance of the jetties at the ocean end of the inlet, and of shore revetments within the inlet in prolongation of the jetties. The two parallel rubblestone jetties with revetment extensions, constructed by local interests to protect the entrance, are 900 feet apart, the north jetty and revetment being about 3,500 feet long, and the south jetty and revetment about 3,200 feet long. The length of the section included in the project is about 3.5 miles. The mean range of tide is about 2.6 feet at the entrance and 0.7 foot at the terminal, with northeast tides as high as 5 feet above mean low water. The actual cost of new work was $337,183. The average annual maintenance cost during the past 5 years was $28,480. The existing project was authorized by the following: Acts Work authorized Documents Deficiency Act of The expenditure of $20,000 for dredging the channel, Specified in Act.

Local cooperation. Fully complied with. Terminal facilities. These consist of 2 earth-filled piers re- tained by steel sheet piling and forming a slip 200 feet wide by 330 feet long with bulkhead wharf at inner end. These facilities afford a berthing space of about 1,653 feet. The south pier and the bulkhead wharf are municipally owned, the pier having a berthing space of 524 feet with depths of 22.0 to 11.0 feet. The steel sheet-pile bulkhead on the south pier is in disrepair. A warehouse (in poor condition, needs extensive repairs) 75 by 280 feet is on the municipal pier and a precooling plant 102 by 365 feet occupies the north pier just landward of which is another warehouse, 50 by 100 feet. A fruit packinghouse 170 by 390 feet is at the west end of the slip. The north pier is served by railway and both piers by highway connections. The slip on north side of the north pier has depths of 21 to 29 feet. North of the turning basin there is a bulkhead wharf with a depth of 8 to 10 feet with ample room for open storage, and with tank storage in the rear for petroleum products. The facilities are considered adequate for existing commerce. (See Port and Terminal Facilities Report, 1941, Corps of Engineers.) Operations and results during fiscal year. Maintenance. United States hopper dredge Hyde removed 104,281 cubic yards of ma- terial, bin measurement, from the entrance channel and turning RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 479 basin, December 5-18, 1956, at a cost of $47,666. Hired labor inspections and reports cost $173. The total costs for the fiscal year were $47,839 for maintenance. Condition at end of fiscal year. The existing project was com- pleted in February 1938. Dredging was begun in July 1936 and completed in February 1938. Restoration of the jetties con- structed by local interests was begun in October 1933, and com- pleted in August 1934 as a maintenance feature. Both jetties are in good condition. The revetments are in poor condition; both are ragged, with nearly vertical faces along the water side, resulting from loss of numerous stones into the water. The westerly 500 feet of the south revetment was repaired in 1956 with broken concrete from the demolition of an adjacent structure and is now in good condition.

PALM BEACH HARBOR, FLA. Location. On the east coast of Florida about 71 miles north of the entrance to Miami Harbor. It is the entrance channel to 480 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the Port of Palm Beach. (See U. S. Coast and Geodetic Survey Chart No. 1248.) Existing project. This provides for maintaining, deepening, and enlarging the improvements constructed by local interests to provide a channel 25 feet deep at mean low water (plus 2 feet of overdepth from the ocean to station 65+00 and 1 foot of over- depth thence to and in the turning basin), and 300 feet wide from deep water in the ocean to station 69+00, thence reducing to a width of 200 feet at station 65+00, near the westerly side of the inlet, thence 200 feet wide across Lake Worth to station 31+54, with widening at the junction with the turning basin, thence flaring to form a turning basin of the same depth on the westerly side of the lake, of irregular shape, varying in length from about 1,375 feet on the north side to 900 feet on the south side, and with a minimum width of 1,250 feet over the westerly 900 feet of its length; for removing the obstructive point on the south side of the inlet; for revetting the banks of the inlet; and for restoring the existing jetties. The jetties constructed at the entrance by local interests consist of two parallel rubblestone structures 800 feet apart, the north jetty and revetment being about 1,800 feet long and the south jetty, 1,700 feet long. The length of section under improvement is about 1.5 miles. The mean range of tide is 2.8 feet at the inlet and 1.8 feet at the Port of Palm Beach terminals. The extreme range is about 4.5 feet at the inlet and 3 feet at the terminals. The actual cost of new work was $1,688,741. The average annual maintenance cost during the past 5 years was $25,547.

Local cooperation. The conditions imposed by the River and Harbor Act of August 30, 1935 (H. Doc. 185, 73d Cong., 2d sess.), have been complied with except for furnishing perpetual ease- ments for access to the easement areas adjacent to the channel through the inlet. The River and Harbor Act of March 2, 1945, among other conditions imposed the requirement that local interests give assurances satisfactory to the Secretary of War RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 481 that they will provide additional berthing space and terminal facilities when needed to accommodate any increase in the com- merce of the port, and furnish suitable spoil-disposal areas for subsequent maintenance of the work as and when required. A resolution adopted August 1, 1945, by the Port of Palm Beach District agreeing to comply with all conditions imposed by the act was accepted by the Secretary of War on October 3, 1945, as satisfactory assurance of compliance. All other requirements imposed by the act of 1945 have been fully complied with. The River and Harbor Act approved May 17, 1950 (H. Doc. 704, 80th Cong., 2d sess.), imposed the condition that local interests furnish assurances satisfactory to the Secretary of the Army that they will furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas for the work and subsequent maintenance, when and as required; and will provide and maintain, in accordance with plans approved by the Chief of Engineers, a new slip with highway and rail connections and other appurtenances, open to all on equal and reasonable terms. In partial compliance, local interests have completed slip No. 2 as described in the paragraph "Terminal facilities." While not required under the conditions of local cooperation, the Port of Palm Beach District, during 1944, dredged the area south and southeast of the then-existing project turning basin to a depth of 12 to 15 feet or to rock. During 1946, the port district widened the turning basin generally 200 feet to the south and east, to a depth of 22 feet. During November and December 1953, local interests enlarged the turning basin, at their expense, by dredging to 25 feet plus 2 feet overdepth, an area 250 feet wide and about 1,900 feet long along the easterly side of the turning basin. Terminal facilities. These consist of 2 slips and a marginal wharf. Slip No. 1 is 690 feet long, 210 feet wide, and 26 feet deep, with a wharf on either side and a bulkhead at the inner end; slip No. 2 is 650 feet long, 225 feet wide, and 32 feet deep, and is bulkheaded on both sides and at the west end. The west end is used for barge unloading and has a depth of 15 feet at the bulkhead. The marginal wharf extends north 454 feet from slip No. 1 along the west side of the turning basin with a depth at dockside of 25 feet. The face of the pier between the two slips is bulkheaded. On the north side of slin No. 1 is a 70- by 620-foot steel and concrete warehouse, a 70- by 140-foot wooden frame building, and an office building; a 36- by 124-foot former precooling plant north of the warehouse has been remodeled for an express traffic warehouse. A new office building completed in 1956, houses the port offices and United States immigra- tion and United States Customs Services. One storage tank for imported sirup and 2 storage depots for petroleum products are connected with the terminal by pipelines. On the pier between slips Nos. 1 and 2 a steel warehouse 60- by 360-feet has been built with paved open storage for bulk cargoes around it. Oil 482 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 pipelines have been installed on both sides of slip No. 2 to enable tankers to unload. Equipment for transferring railroad freight cars to and from car ferries has been installed and is used ex- tensively. Rail and highway connections, water supply, and other facilities have been provided in the warehouses and ship- side on the slips. A railroad spur track south of slip No. 2 serves the 131,000 kilowatt plant of the Florida Power and Light Co. Two additional railroad spurs were built in 1956 on each side of slip No. 2 principally for handling scrap metal shipments. The port's railroad trackage east of the Federal Highway totals about 3 miles. These facilities afford total berthing space of 3,929 feet, with depths of 17 to 32 feet. All wharves belong to the Port of Palm Beach District. Two areas west of slip No. 2 are leased to firms which manufacture and distribute concrete building products. West of slip No. 1 a paved area 240 feet by 300 feet is provided for open storage of lumber. On the port property west of the Federal Highway the West India Fruit and Steamship Co., which operates the railroad car ferries, has a 40- by 800-foot roofed platform for handling Cuban fruits and vegetables. One mile of spur track has been built to serve this facility, and more than 2 additional miles of railroad track have been built for railroad yards and switching purposes on port lands west of the Federal Highway. A paved entrance roadway 80 by 300 feet leads to the port facilities west of the Federal Highway. The roofed platform there is provided with a paved area 30 by 900 feet on the north side and 60 by 900 feet on the south side. The U. S. Naval Reserve and U. S. Coast Guard are provided with warehouse and shop facilities on port property. The port facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: United States hopper dredge Hyde removed 81,551 cubic yards of material, bin measurement, from the entrance channel and turning basin, November 19-December 4, 1956, at a cost of $28,442. Hired labor surveys, inspections, and reports cost -- $1. The total costs for the fiscal year were $28,441 for maintenance. Condition at end of fiscal year. The existing project was com- pleted in July 1950. Between 1918 and 1920, local interests dredged a channel 15 to 18 feet deep, 300 feet wide through the inlet, and 150 feet wide across Lake Worth, with a turning basin on the western shore of the lake, and constructed two stone jetties and revetment extensions to protect the channel at the entrance. The United States deepened the entrance channel and turning basin to 20 feet and widened the channel across Lake Worth to 200 feet between February 1935 and December 1937, and restored the stone jetties and revetments and removed the obstructive land point at the south side of the inlet between October 1936 and June 1938. The entrance channel and turning basin were further deepened to 25 feet, plus overdepth, between March 1947 and No- vember 1948. During July 1949, local interests began dredging, on a reimbursable basis, to extend the turning basin 550 feet RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 483 southward, with a flare to the east. The work was later discon- tinued, but was resumed by them during June 1950 and completed in July 1950. Local interests were reimbursed for the work in November 1951. During November and December 1953, local interests again enlarged the turning basin at their expense and not on a reimbursable basis. The latest enlargement involved dredging to 27 feet deep an area about 250 feet wide and 1,900 feet long along the entire easterly side of the turning basin. As reconstructed, the north jetty and revetment are 950 and 1,500 feet long, respectively; 850 feet of the shoreward end of the jetty has been capped with concrete, and voids in the granite en- rockment at the seaward end of the structure have been filled with asphaltic concrete which is now in poor condition. The south jetty and revetment are 1,890 and 420 feet long, respectively; 1,790 feet of the shoreward end of the jetty has been capped with concrete. Repairs by contract were performed on the south jetty and revetment, and new granite base rocks were placed on both sides of the concrete cap for its full length. The work was completed September 8, 1950. Rebuilding of the north revetment was completed in April 1950. Both jetties were in good condition except for hurricane and storm damages to the south jetty as follows: Due to displacement and scattering of outlying granite base rocks formerly protecting the concrete cap, the outer 500 feet of concrete cap has settled generally from 1 to 6 inches: two 40-foot sections of the concrete cap were badly cracked longi- tudinally-one 400 feet from the east end of the concrete cap, the other near the land end; and the 100-foot section of nonbonded rubble granite at the seaward end is in good condition since its repair in 1950. The gully along the landside of the west half of the concrete cap on the north jetty continued to enlarge by erosion of sand leaking under the cap into the inlet through large voids in the underlying base rock. Repair of this condition begun by contract in April and completed in June 1955, included placement of large granite boulders along channel side of concrete cap as protection from storm-wave action.

MIAMI HARBOR, FLA. Location. Miami is near the northerly end of Biscayne Bay, about 335 miles southeasterly from the entrance to Jacksonville Harbor. Miami River has its source in the Everglades and flows southeasterly to enter Biscayne Bay at Miami. (See U. S. Coast and Geodetic Survey Charts Nos. 547 and 1248.) Existing project. This provides for the following: (a) A channel 30 feet deep and 500 feet wide from the 30-foot contour in the ocean to near the outer end of the north jetty, thence 300 feet wide through the entrance and across Biscayne Bay to and including a turning basin 1,400 feet long and 1,350 feet wide on the westerly side of Biscayne Bay in front of the municipal ter- minals at Miami; (b) two parallel rubblestone jetties at the en- trance, 1,000 feet apart and 3,000 and 2,750 feet long, respectively; (c) a channel 15 feet deep and 200 feet wide from the mouth of Miami River to the turning basin at the municipal terminals; (d) a channel 8 feet deep and 200 feet wide from the mouth of Miami River to the Intracoastal Waterway and thence 100 feet wide to Government Cut; (e) a channel at the mouth of Miami River, 15 feet deep at mean low water, 250 feet wide at the outer end and ta- pering to 170 feet wide at Brickell Point in a distance of about 1,400 feet; thence a channel in Miami River, 15 feet deep under flood conditions, 150 feet wide for 3 miles, thence 125 feet wide for 1.1 miles, and thence 90 feet wide for 1.4 miles; (f) a channel 12 feet deep and 100 feet wide from Miami River to a harbor of refuge in Palmer Lake, the location of the harbor of refuge and channel leading thereto being subject to modification at the discre- tion of the Chief of Engineers, and (g) an approach channel 6 feet deep and 700 feet wide to the harbor line at the seaplane base at Dinner Key, with an enlargement at the inner end and with a chan- nel 8 feet deep and 50 feet wide along the easterly edge of the widening. RIVERS AND HARBORS--JACKSONVILLE, FLA., DISTRICT 485 The plane of reference is mean low water, except for the 15-foot channel in Miami River where depths are based on flood conditions. The total length of the waterway under improvement is about 17.7 miles, including about 6 miles of entrance channel from the ocean to and including the turning basin at the municipal terminals, 5.8 miles in Miami River, 3.5 miles in the connecting channels leading therefrom into the bay, and 0.8 mile at Dinner Key Airport. The mean tidal variation is 2.5 feet at the entrance and 2 feet in the bay. The extreme variation is about 4.5 feet at the entrance and 3 feet in Biscayne Bay. Strong easterly winds raise the water level about 1.5 feet at the entrance and 1 foot in the bay. Strong westerly winds lower the water level about 1 foot at the entrance and about 0.5 foot in the bay. The estimate of cost for new work (July 1956) is $7,379,000, excluding $23,000 to be contributed by local interests. The average annual maintenance cost during the past 5 years was $18,624. The Virginia Key portion of the project is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1953, and was estimated to be $7,451,200.

Local cooperation. All work authorized by the River and Har- bor Act approved March 2, 1945, is subject to the conditions that 486 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 local interests furnish, free of cost to the United States, all lands, easements, and rights-of-way and suitable spoil-disposal areas for the initial work and subsequent maintenance, as and when re- quired, and hold and save the United States free from claims for damages resulting from the improvement. In addition, the pro- vision of a channel from Miami River to the harbor of refuge is subject to the conditions that local interests contribute one-third of the initial cost of the channel, furnish assurances satisfactory to the Secretary of War that they will provide and maintain suit- able depths in the harbor of refuge and construct and maintain adequate mooring facilities therein, and agree that, at any time upon the approach of a hurricane or severe storm and specifically upon the request of the district engineer or his authorized repre- sentative, the refuge basin will be open to all without charge until storm danger is past. On September 5, 1945, the Commission of the city of Miami, Fla., adopted a resolution agreeing to assume responsibility for compliance with the local cooperation requirements imposed in House Document 91, 79th Congress, 1st session, except those per- taining to the channel from Miami River to the harbor of refuge in Palmer Lake. On May 9, 1946, that resolution was accepted by the Secretary of War as satisfactory assurance of partial compliance. All prior requirements have been fully complied with. Terminal facilities. These consist of 45 piers and wharves of which one is on Fisher Island, three are at Miami Beach, five are along the south side and one is along the westerly bend of Mac- Arthur Causeway; 10 are along the west side of Biscayne Bay at Miami, and 25 are on Miami River. Six of the facilities are open to the public for handling general cargo. Four of these, including three municipal piers on the west side of the bay and a privately owned wharf near the east end of the MacArthur Cause- way, accommodate deep-draft vessels. The other two general cargo facilities are suitable for small vessels, and include the Florida East Coast Railway wharf south of the municipal piers, and one privately owned wharf on Miami River. All of the general cargo wharves have highway and railway connections, except the cause- way terminal which has highway connections only. A municipal yacht anchorage and basin and a municipal wharf are open to the public for recreational craft. Of the remaining piers and wharves, four in the bay and three on Miami River are used for handling petroleum products, 17 are used in connection with ship repair activities, and six are used for mooring vessels or handling private freight. Three of these facilities have railway connec- tions, and all have highway connections, except a petroleum wharf on Fisher Island. In addition, numerous landing facilities in and around Miami, especially on Miami River, at Dinner Key, and at Crandon County Park are designed for and used exclusively by recreational craft. The facilities are considered inadequate for the existing commerce. (See Port Series No. 16, revised 1947, Corps of Engineers.) RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 487 Operations and results during fiscal year. Hired labor mainte- nance of United States reservation and bank revetments through- out year cost $6,011. Hired labor inspections and reports cost $702. The total costs for the fiscal year were $6,713 for maintenance. Condition at end of fiscal year. The existing project was about 49 percent completed. The main 30-foot entrance channel from the ocean to and including the turning basin was dredged progres- sively between August 1904 and March 1939. A landcut 20 feet deep and 300 feet wide was dredged across the peninsula to Bis- cayne Bay between August 1904, and October 1923; a channel 25 feet deep from the ocean, to and including the former municipal turning basin at Miami (200 feet wide across the bay, and follow- ing the alinement of the former municipal channel), was dredged between July 1926, and December 1933, and was deepened to 30 feet, including widening the channel across the bay to 300 feet and enlarging the turning basin, between April 1934 and March 1939. A channel 15 feet deep at mean low water and 150 feet wide along the land point at the mouth of Miami River for 1,400 feet, and thence northerly along the bay front for about 1,200 feet, and a channel in Miami River for 5.5 miles above its mouth, 15 feet deep under flood conditions and of project widths, were dredged between March 1932 and August 1933. The channels at the Dinner Key seaplane base were dredged between February and August 1933. These facilities are no longer used by aircraft, and the Dinner Key base was taken over by the city of Miami in 1947, converted to accommodate pleasure boats, and is now known as the Dinner Key Marina. The 2 stone jetties at the entrance were constructed to the 18-foot contour between March 1904, and October 1908, extended 405 feet each in 1922, and extended to their present lengths between September 1926, and March 1929. The north jetty and revetment is 4,688 feet long, and the south jetty and revetment is 3,850 feet long. The south jetty, both revetments, and that part of the north jetty landward of the low tide shoreline in the ocean are in good con- dition. Seaward of the low tide shoreline the north jetty is in fair condition; that section was damaged during the November 1935. hurricane. Pieces of granite dislodged from the upper part of the jetty now lie on the ocean bed beside the jetty. At several points in the jetty, the crest has been lowered to the plane of mean high tide. The work remaining to be done to complete the project is as follows: Widen the channel at the mouth of Miami River by 20 to 100 feet for 1,400 feet; widen the existing channel along the southerly end of Bayfront Park north of Miami River to 200 feet, and thence provide a channel 15 feet deep and 200 feet wide to the turning basin in front of the municipal terminals; provide a chan- nel 8 feet deep, 200 feet wide from the mouth of the river to the Intracoastal Waterway, and thence 100 feet wide to Government 488 REPORT OF THE CHIEF OF ENGINEERS, U.

OKEECHOBEE WATERWAY, FLA. Location. Caloosahatchee River has its source in Lake Okeecho- bee and flows generally southwesterly, emptying into the Gulf of Mexico through San Carlos Bay, about 30 miles south of the en- RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 489 trance to Charlotte Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 473, 1247, 1255, and 1289.) Lake Okeechobee is a large, fresh-water lake in south central Florida. (See U. S. Coast and Geodetic Survey Chart No. 1289.) St. Lucie Canal was constructed by the Everglades Drainage District as a control canal for Lake Okeechobee. It begins at about the middle of the east shore of Lake Okeechobee, and empties into the south fork of the St. Lucie River at St. Lucie lock. The length of the canal is 23.9 miles. (See U. S. Coast and Geodetic Survey Chart No. 1289.) St. Lucie River, South Fork, flows north from the entrance of the St. Lucie Canal about 7.4 miles to Stuart, where it joins North Fork to form the St. Lucie River, thence east, southeast, and east about 7.7 miles, emptying into the Indian River opposite St. Lucie Inlet. (See U. S. Coast and Geodetic Survey Charts Nos. 1247 and 1289.) Taylor Creek is formed by several small streams in central Okeechobee County, and flows generally southeasterly, emptying into Lake Okeechobee at its most northerly extremity. (See U. S. Coast and Geodetic Survey Chart No. 1289.) For description of above waterways see p. 705, Annual Report for 1932.) Previous projects. Original projects for Caloosahatchee River below and above Fort Myers were adopted by River and Harbor Acts of August 2, 1882, and August 11, 1888, respectively. The next project was adopted by the River and Harbor Act approved June 25, 1910, which authorized the present project depths in Caloosahatchee River from Fort Myers to the Gulf of Mexico, with a turning basin at Fort Myers, and was modified by the River and Harbor Acts approved July 3, 1930, and August 30, 1935, under the title "Caloosahatchee River and Lake Okeechobee drainage areas, Florida," to provide, among other things, for a navigable channel across the State and for control of Lake Okeechobee, in- cluding construction of locks at Ortona and Moore Haven. For further details see page 1828, Annual Report for 1915; page 707, Annual Report for 1932; pages 878-888, Annual Report for 1948; and pages 785 and 831, Annual Report for 1949. Existing project. This provides for: (a) Replacing old locks Nos. 1 and 2, St. Lucie Canal, by a single new lock with a usable width of 50 feet, a usable length of 250 feet, a depth of not less than 8 feet over the sills, and a new weir structure; (b) a channel 8 feet deep from Fort Myers to the Intracoastal Waterway near Stuart, with widths of 90 feet from Fort Myers to Moore Haven, thence 80 feet along the southerly shore of the lake to the hurri- cane gate at Clewiston, thence 100 feet across Lake Okeechobee to and in the St. Lucie Canal to St. Lucie lock, and thence 80 feet to the Intracoastal Waterway; (c) a channel 8 feet deep and 100 feet wide from the project turning basin to the existing municipal yacht basin at Fort Myers; and (d) under maintenance, the operation and care of St. Lucie lock. 490 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The project also includes maintenance of features completed under previous projects as follows: (a) A channel 12 feet deep and 200 feet wide from the Gulf of Mexico to Punta Rasa, about 3.8 miles, thence 10 feet deep and 100 feet wide to Fort Myers (Edison Memorial Bridge), about 16.3 miles, with a turning basin at that point; (b) a channel in Taylor Creek 6 feet deep when the lake is at elevation 12.56 mean sea level, and 60 feet wide from the town of Okeechobee into the lake, 4 miles; (c) a navigation chan- nel 6 feet deep and 80 feet wide following in general the south shore of Lake Okeechobee from Clewiston to the St. Lucie Canal, 36.7 miles; and (d) the operation and care of the Moore Haven and Ortona locks. The total length of the waterway from the Gulf of Mexico to the Intracoastal Waterway is about 154.6 miles via the channel across Lake Okeechobee, or about 165.3 miles via the channel along the south shore of the lake. On July 1, 1947, mean sea level datum, which is 1.44 feet above the Lake Okeechobee datum previously used between the St. Lucie and Ortona locks, was adopted for use throughout the project.

The mean range of tide at Punta Rasa is 1.7 feet and at Fort Myers, 0.7 foot. The extreme range is about 4.5 feet at Punta RIVERS AND HARBORS---JACKSONVILLE, FLA., DISTRICT 491 Rasa and about 2 feet at Fort Myers. At low-river stage, tidal influence is perceptible at the Ortona lock, 57.3 miles above Punta Rasa. The mean range of tide at St. Lucie Inlet is 2.6 feet and the extreme range, about 4.5 feet. Tidal effect is perceptible to St. Lucie lock, 15.1 miles. Lake Okeechobee is maintained, so far as possible, between elevations 13 and 15 feet, mean sea level. The Federal cost for new work, excluding amounts expended on previous projects, is $3,803,448. The average annual main- tenance cost during the past 5 years was $199,728. The Stuart basin portion of the project is to be restudied and is excluded from the foregoing cost estimate. The cost of this portion was estimated to be $5,000 in 1954.

Local cooperation. All work authorized by the River and Harbor Act approved March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas when and as required for the initial work and for subsequent maintenance, and hold and save the United States free from all claims for dam- ages resulting from the improvement. The provision of a channel from the project turning basin to the municipal yacht basin at Fort Myers is subject to the additional requirements that local interests provide, maintain, and operate adequate mooring and servicing facilities open to all on equal and reasonable terms, and make addi- tional improvements to protect the Fort Myers yacht basin from wave action. A resolution adopted November 10, 1945, by the Board of Com- missioners of the Okeechobee Flood Control District (an agency created by the State of Florida to comply with the requirements imposed by the River and Harbor Act of July 3, 1930) agreeing to comply with the requirements of local cooperation imposed in reference to deepening the waterways to 8 feet between Fort Myers and the Intracoastal Waterway (H. Doc. 696, 76th Cong., 3d sess.) was accepted by the Chief of Engineers on February 18, 1946, as satisfactory assurance of compliance. All lands and spoil-disposal areas required for the initial work of deepening the waterway to 8 feet have been furnished. On July 28, 1949, the Okeechobee 492 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Flood Control District adopted two resolutions transferring the agreements, commitments, and assets of the Okeechobee Flood Control District to the Central and Southern Florida Flood Con- trol District. On July 14, 1949, the Central and Southern Florida Flood Control District adopted a resolution accepting the assets of the Okeechobee Flood Control District and assuming its agree- ments and commitments as of midnight July 31, 1949. On Novem- ber 25, 1949, the Chief of Engineers authorized the Jacksonville district engineer to notify both districts that the subject transfer was satisfactory to the Corps of Engineers. A resolution adopted November 17, 1949, by the City Council of Fort Myers, agreeing to comply fully with all the requirements in connection with the side channel at Fort Myers as set forth in House Document 736, 79th Congress, 2d session, was accepted by the Chief of Engineers on January 23, 1950, as satisfactory assur- ances of compliance. All prior requirements have been fully complied with. Terminal facilities. In the vicinity of Fort Myers on the Caloo- sahatchee River, these consist of three freight piers, one railroad terminal pier, one municipal recreation pier, four privately owned piers, and a municipal yacht basin. A mooring basin has been provided at La Belle. There are numerous small wooden-pile landings along the upper Caloosahatchee River, along the lake shore, on St. Lucie Canal, and on St. Lucie River, including one railroad terminal pier, a municipal pier, and a pier for handling petroleum products at Stuart. Marginal wharves with highway and railway connections are available along the waterway, as follows: 125-foot wharf at LaBelle; 180-foot wharf at Clewiston; 150-foot wharf at Belle Glade; 125-foot wharf at Moore Haven; 50-foot wharf at Alva; and 30-foot wharf on Taylor Creek at the town of Okeechobee. A breakwater and turning basin installation with highway connec- tion at Pahokee, Florida provides 1,000 feet of wharf and other limited harbor facilities on the east shore of Lake Okeechobee. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Ex- tension to the control house at Moore Haven was accomplished by contract, December 21, 1956-January 31, 1957, at a cost of $4,205. Traffic warning gates were installed at Moore Haven Lock by contract during June 1957 at a cost of $3,691. A safety fender system was installed at Ortona Lock during November and December 1956 and a traffic warning gate was installed in June 1957, all by hired labor, at a cost of $5,072. Sunken obstruc- tions in the waterway were removed by hired labor throughout the year at a cost of $955. Operating and care: Moore Haven and Ortona Locks on the Caloosahatchee River and St. Lucie Lock on the St. Lucie Canal were operated and maintained by hired labor throughout the year at a cost of $70,191. Hired labor surveys and inspections cost $6,452. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 493 The costs of all work for the fiscal year were $16,498 for mainte- nance and $74,068 for operation and care, a total of $90,566. Condition at end of fiscal year. The existing project was com- plete. Construction of St. Lucie lock and spillway at the lower end of St. Lucie Canal near Stuart was begun in August 1939 and completed in June 1943 except for installation of tainter gates in the spillway, which was completed in March 1950. An auxiliary lock gate has been installed in the upstream end of old lock No. 2, which was constructed by the Everglades Drainage District, and lies adiacent to and supnlements the new lock. Dredging to deepen the waterway to 8 feet between Fort Myers and the Intra- coastal Waterway near Stuart, with overdepth in St. Lucie Canal, was begun in June 1948, and completed August 9, 1950, with dredging to provide a channel 8 feet deen and 100 feet wide to connect the project turning basin at Fort Myers with the municipal yacht basin. Features completed under the previous project and maintained under the existing project are as follows: A channel 12 feet deep and 200 feet wide from the Gulf of Mexico to Punta Rasa, and thence 10 feet deep and 100 feet wide to Fort Myers, with a turn- ing basin at that locality, January 1911 to January 1913; the im- proved Caloosahatchee Canal and River channel from Moore Haven to Fort Myers, 56.5 miles, providing a floodway and navi- gation channel at least 7 feet deep and 90 feet wide, and with a discharge-outlet capacity of 2,500 cubic feet per second from Lake Okeechobee, February 1931 to June 1937: a channel 8 feet deep and 80 feet wide in St. Lucie River between Palm City bridge and St. Lucie lock, about 2.8 miles, September to December 1931; a chan- nel 6 feet deep and 60 feet wide in Taylor Creek from the town of Okeechobee to Lake Okeechobee, about 4 miles, July 1936 to March 1938: 58.3 miles of naviegation channel from Moore Haven lock to St. Lucie Canal, generally 8 feet or more deep with a minimum width of 80 feet, following in general the south shore of the lake, January 1932. to March 1936; a lock at Ortona, and a combined lock and hurricane gate at Moore Haven, November 1934 to June 1943. For work constructed under previous projects and now main- tnined under the flood-control project for central and southern Florida, see paragraph "Existing project," central and southern Florida. For information relative to the St. Lucie, Moore Haven, and Ortona locks, see table in the paragraph "Existing project." Depths in excess of 8 feet exist in the St. Lucie Canal and in the channel following in general the south shore of Lake Okeechobee. St. Lucie Canal was constructed 8 feet deep and 150 to 165 feet wide by the Everglades Drainage District between 1916 and 1928 as a control canal for Lake Okeechobee. The controlling depths when last surveyed were as follows: Gulf of Mexico to Punta Rasa, 12 feet for a width of 200 feet in August 1950; Punta Rasa to" Fort Myers, 10 feet for a width of 100 feet in August 1950; Fort 494 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Myers to Ortona lock, 8 feet for a width of 90 feet in August 1950; Ortona lock to Lake Okeechobee at Moore Haven, 8 feet for a width of 90 feet in April 1949; Lake Okeechobee from Moore Haven to St. Lucie Canal via south-shore channel, 9 feet for a width of 50 feet in April 1949; via Liberty Point floodway channel and open lake, 5 feet for a width of 60 feet in April 1950; via Clewiston approach channel, 8 feet for a width of 100 feet in March 1950; Lake Okeechobee to St. Lucie lock, 9 feet for a width of 80 feet in November 1949; St. Lucie River from the lock to Intracoastal Waterway near Stuart, 8 feet for a width of 80 feet in March 1950; and Taylor Creek from the town of Okeechobee to Lake Okeechobee, 6 feet for a width of 60 feet in February 1949. The present controlling channel width of 80 feet is reduced to 50 feet at locks and at 19 localities by bridges. The total costs under the existing project to June 30, 1957, have been $3,803,478 for new work, $512,681 for maintenance, and $1,077,872 for operation and care, a total of $5,394,031.

Knight Field, Davis Islands, about 2,000 feet long and partially inclosing a landing basin for seaplanes (main- tenance to be assumed by local interests). The length of the section included in the existing project is about 66.4 miles, including about 10.0 miles in the Hillsboro River and about 3.6 miles in the Alafia River Channel. The plane of reference is mean low water. The mean range of tide is 1.3 feet at the lower end of the bay, 1.6 feet at Port Tampa, and 1.8 feet at Tampa. The extreme range is about 3.8 feet at the lower end of the bay and 4.8 feet at Tampa. Strong southwesterly winds raise the water level about 1.5 feet. Strong northerly winds, which usually occur in winter, lower the water level about 2 feet. The estimate of cost of new work (July 1956) is $22,400,000, excluding amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $30,917, excluding the breakwater at Peter O. Knight Field. Local cooperation. The River and Harbor Act of June 20, 1938 (S. Doc. 164, 75th Cong., 3d sess.), authorized widening the bend between Sparkman Channel and Cut D of Hillsboro Bay Channel by 250 feet, widening Ybor Channel from 300 to 400 feet, and extending the turning basin at the west end of Garrison Channel easterly for 300 feet, subject to the conditions that local interests furnish, free of cost to the United States, necessary rights-of-way and suitable spoil-disposal areas for new work and for subsequent maintenance as required, and move and reconstruct all bulkheads, wharves, buildings, roads, railroad tracks, and all other structures as may be necessary. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 497 The River and Harbor Act of March 2, 1945, authorized the further widening of Ybor Channel to 500 feet, widening Sparkman Channel to 400 feet, widening the bend between Garrison and Sparkman Channels, and reducing the widening between Seddon and Garrison Channels from 300 to 150 feet (S. Doc. 183, 78th Cong., 2d sess.), subject to the conditions that the city of Tampa agree to commence and complete promptly, the construction of the beltline railroad and the paving of streets on the north and east sides of Ybor Channel (first required by River and Harbor Act of August 8, 1917, and complied with as regards the west side of the channel) when necessary in the judgment of the Secretary of War; and provided further, that local interests furnish, free of cost to the United States, all lands required for the provision of the improvements and for the disposal of dredged material during construction, and for subsequent maintenance as and when re- quired, and construct such bulkheads and retaining walls, and strengthen or move adjacent structures, as may be required to safeguard both the channels and the adjacent lands and structures, all in a manner satisfactory to and approved by the Chief of Engineers and the Secretary of War, and agree to hold and save the United States free from claims for damages resulting from the improvement. In 1945 the Florida Legislature adopted a bill creating the Hillsborough County Port Authority as the governing body and authority of the area defined in the act as Hillsborough County Port District, comprising approximately the northwest quarter and part of the southwest quarter of Hillsborough County. It includes all channel and terminal areas of Tampa and Port Tampa, but excludes the Alafia River and the relatively undeveloped area east of the upper harbor. On September 9, 1949, the Hillsborough County Port Authority adopted a resolution agreeing to comply with all conditions imposed in Senate Document 164, 75th Con- gress, 3d session. On October 11, 1949, the port authority adopted a resolution agreeing to, and assuming full responsibility for compliance with, the requirements as set forth in Senate Document 183, 78th Congress, 2d session, except any requirement to extend the trackage of the municipal beltline railroad (extension not now required in accordance with the provisions of the River and Harbor Act of May 17, 1950), but specifically including the obligation in respect to the portion thereof already completed. The Chief of Engineers accepted those resolutions on November 21, and December 28, 1949, respectively, as satisfactory assurance of compliance. The port authority has furnished, or caused to be furnished, all lands, easements, rights-of-way, and spoil-disposal areas required for new work provided for in those documents. All streets on the west side of Ybor Channel have been paved, and the through streets on the north and east sides have been paved. In addition, the port authority has furnished evidence satisfactory to the district engineer that the United States will be held harmless in the event of sloughing of banks as a result of dredging. The width of Ybor Channel has been restricted to a minimum of 480 feet at some localities to make unnecessary 498 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the construction of bulkheads and retaining walls and the strengthening or moving of structures. The River and Harbor Act approved March 2, 1945, authorized certain improvements in Hillsboro River (H. Doc. 119, 77th Cong., 1st sess.), subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, rights-of- way, and suitable spoil-disposal areas for initial work and subse- quent maintenance when and as required; agree to make at their expense necessary alterations to structures crossing the river; and hold and save the United States free from claims for damages resulting from the improvement. The Hillsborough County Port Authority was requested on June 3, 1956, to execute its previous offer to furnish assurances that it will comply with these requirements when funds are made available. The work authorized by the River and Harbor Act approved May 17, 1950, is subject to the conditions that for new work responsible local interests give assurances satisfactory to the Secretary of the Army that they will: (a) Provide without cost to the United States all lands, easements, rights-of-way, and spoil- disposal areas necessary for construction and subsequent mainte- nance of the project, when and as required; (b) hold and save the United States free from damages due to the construction and subsequent maintenance of the works; (c) construct such bulk- heads and retaining works, and strengthen or move adjacent structures as may be required, prior to dredging, to safeguard the channels, basins, and adjacent lands and structures, in accordance with plans approved by the Chief of Engineers; (d) provide, prior to or concurrently with the Federal improvement, additional or enlarged slips and berthing space with necessary terminal facilities at Port Tampa in accordance with plans approved by the Chief of Engineers; (e) open existing terminal facilities in Alafia River to all at the same rates and charges that apply to other Tampa Harbor terminals and expand those facilities as and when required to meet the needs of commerce; and (f) open the terminal facilities at Tampa Harbor to all on equal terms. The project document further provides: (1) that the existing conditions of local cooperation whereby approval of wharfage charges by the Secretary of War is required (River and Harbor Act of August 8, 1917), be revoked; (2) that the requirements pertaining to the municipal beltline railroad imposed by the River and Harbor Act of August 8, 1917 (H. Doc. 1345, 64th Cong., 1st sess.) and by the River and Harbor Act of March 2, 1945 (S. Doc. 183, 78th Cong., 2d sess.) be modified so as to require no further extension of trackage with the understanding that the city's obligation with respect to the completed portion shall remain in force until relieved by the Chief of Engineers. The River and Harbor Act approved September 3, 1954, authorized additional improvement in Hillsboro River (H. Doc. 567, 81st Cong., 2d sess.), subject to the condition that responsible local interests give assurances satisfactory to the Secretary of the Army that they will (a) provide without cost to the United States all lands, easements, and rights-of-way necessary for the construction of the project; (b) provide at their own expense all necessary alterations to structures RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 499 and utilities; (c) hold and save the United States free from damages due to the construction works; and (d) maintain the cleared channel after completion in accordance with regulations prescribed by the Secretary of the Army. A resolution adopted July 11, 1955, by the Hillsborough County Port Authority was accepted July 27, 1955, as satisfactory assur- ances of compliance with all requirements of local cooperation imposed by the River and Harbor Act of 1950, for improvement of all main channels of Tampa Bay and Port Tampa, and Alafia River. Despite the fact that the latter is not in the port district area, the Authority has accepted representation of all interests for Federal improvement of Tampa Harbor project. Assurances have been requested from the Authority relating to Hillsboro River dredging, clearing and snagging, authorized by the River and Harbor Acts of 1945 and 1954. All other and prior requirements have been met. Terminal facilities. There are 57 piers and wharves at Tampa, including 14 on Hillsboro River at Tampa, 28 other piers within the Tampa City limits, one at East Tampa, 13 on the slip at Port Tampa, and one on Old Tampa Bay at Rattlesnake, Fla. Those on Hillsboro River are suitable for small vessels drawing up to 11 feet; all others are used by deep-draft vessels. The municipal terminals are on Ybor Channel and consist of a slip 778 feet long, 250 feet wide, with a wharf on either side, one of which has a steel-frame transit shed. The city of Tampa also owns a shore wharf on Hillsboro River and another on Garrison Channel. Forty-eight of the facilities, including the municipal slip, have railway connections, and all have highway connections. The municipal terminals, one city wharf, and 10 private terminals are open to the public. The piers and wharves on the various channels are used principally as follows: 39 for general cargo and private commodities, 10 for mooring or berthing vessels at shipyards, and three for various industrial purposes; five are not in use. The facilities are considered adequate for the existing commerce except at Port Tampa. (See Port Series No. 17, revised 1947, Corps of Engineers.) Operations and results during fiscal year.

Condition at end of fiscal year. The existing project was about 68 percent completed. Dredging was begun in August 1899 to provide a channel 24 feet deep and of sufficient width from the Gulf of Mexico to Port Tampa, and in November 1910, to provide a channel of the same depth in Hillsboro Bay to Tampa. Dredging has been continued intermittently to secure greater depths and widths as authorized from time to time. Egmont Channel, 29 feet deep and 500 feet wide was completed in July 1931, and channels 30 feet deep, 400 feet wide at Mullet Key Cut and Tampa Bay Channel Cut A, 300 feet wide thence to and including the Port Tampa Channel, Hillsboro Bay Channel, Seddon Channel, Spark- man Channel, Ybor Channel, and 275 feet wide in Garrison Chan- nel were completed in June 1936.

Sparkman Channel was widened to a total width of 400 feet and the bends between Sparkman Channel and Cut D of Hillsboro Bay Channel were widened to project dimensions between July 1947 and May 1949. A turning basin 2,750 feet long and 550 feet wide was dredged at the entrance to the Port Tampa terminals between November 1933 and December 1935. The turning basin at the entrance to Ybor Channel was completed in July 1947, and that at the west end of Garrison Channel (mouth of Hillsboro River), in May 1949. Ybor Channel was widened to its present width between April and June 1950. Project dimensions were provided in Tampa Bay Channels between March 7, 1956 and April 16, 1957. A channel 12 feet deep and 200 feet wide in Hillsboro River from the mouth to within 100 feet of the Lafayette Street Bridge was dredged between December 1899 and about June 1905, under a previous project, and has been maintained under the existing project. The breakwater of dredged material at Peter O. Knight municipal airport was constructed from August 1940 to January 1941, and the city of Tampa has formally assumed responsibility for its care, preservation, and maintenance.

Doc. 258, 81st Cong., 1st sess.). 13. ST. PETERSBURG HARBOR, FLA. Location. St. Petersburg is on the west shore of Tampa Bay 8.75 miles southwest of Port Tampa City. The entrance from the Gulf of Mexico to Tampa Bay is about midway of the west coast of the Florida peninsula, about 330 miles southeast of Pensacola, Fla., and 65 miles northerly from Charlotte Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 586, 587, and 1257.) Previous projects. Adopted by River and Harbor Acts of July 25, 1912, and August 8, 1917. For further details see page 769, Annual Report for 1929, and page 671, Annual Report for 1938. Existing project. This provides for: (a) a channel 250 feet wide, 19 feet deep, leading westward from that depth in Tampa Bay to the basin at the Port of St. Petersburg, a distance of about 1 mile; (b) a depth of 21 feet, 1,400 to 1,700 feet long and 900 feet wide, in the Port of St. Petersburg; (c) a basin in Bayboro Harbor 12 feet deep, 700 to 1,400 feet long, and 800 feet wide; (d) a channel 12 feet deep, 75 feet wide, and 300 feet long in the mouth of Salt Creek; and (e) an entrance channel from the south, 20 feet deep and 200 feet wide extending northerly about 5.5 miles from deep water in lower Tampa Bay, and thence a channel 19 feet deep and 250 feet wide leading westward to the 24-foot-depth entrance channel. The general plan for construc- tion of items (c) and (d) is subject to such modifications as in the discretion of the Secretary of the Army and the Chief of Engineers may seem advisable. The Deficiency Act of March 4, 1929, authorized the expenditure of $17,000 for dredging a chan- nel 16 feet deep and about 200 feet wide on the easterly side of, and as close as practicable to, the Point Pinellas lighted beacon, bearing about 328 ° true. The total length of the project is about 8.9 miles. The plane of reference is mean low water. The mean range of tide in Tampa Bay is 1.5 feet; the spring range, 1.9 feet. Strong southwesterly winds raise the water level as much as 1.5 feet; strong northerly winds, mostly in winter, lower it as much as 2 feet. The estimate of cost for new work is $212,000 (July 1957), exclusive of amounts expended on previous projects, but including $17,000 for the Point Pinellas Channel. No maintenance has been accomplished during the past 5 years; the approved estimate (1950) is $9,000. The parts of the project authorized by the River and Harbor Act adopted May 17, 1950, except the 12-foot depth in Bayboro Harbor and the 12-foot-depth channel at the mouth of Salt Creek, are considered to be inactive and are excluded from the foregoing cost estimates. The cost of those inactive parts was last reviewed in July 1955, and was estimated to be $269,000.

Local cooperation. The River and Harbor Act approved May 17, 1950, imposed the condition that local interests give assurances satisfactory to the Secretary of the Army that they will: (a) furnish, without cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas necessary for the initial construction and subsequent maintenance, when and as required, (b) hold and save the United States free from damage due to the construction works and subsequent maintenance, and (c) strengthen or move such municipal and privately owned structures as may be necessary to safeguard both the channels and adjacent lands and structures. All prior requirements have been fully complied with. Terminal facilities. At the Port of St. Petersburg turning basin, these consist of a municipal concrete wharf 1,500 feet long and two warehouses on the north side of the basin. The space between the Port of St. Petersburg and Bayboro Harbor is occupied by the United States Maritime Service training station, with about 1,360 feet of wharfage space available. The United States Coast Guard depot is south of the entrance channel and east of Salt Creek. On the north, west, and south sides of Bayboro Harbor are five oil company wharves, two marine repair and supply plants, a sand and shell wharf, six marine railways, the steam-electric plant and fuel wharf of the Florida Power Corporation, and four privately owned marginal wharves. Two oil companies have terminals on Salt Creek. Three municipal yacht basins, the Atlantic Coast Line Railroad Pier and the Municipal Recreational Pier are north of the Port of St. Peters- burg. The railroad pier is used for switching purposes and is not available to harbor traffic. None of the terminals have rail connections; all are served by paved highways. The facilities are considered adequate for the existing and immediately prospective commerce, and are open to all on equal terms. Operations and results during fiscal year. New work. Dredg- ing, by contract, to provide project dimensions in Bayboro Harbor and Salt Creek was begun June 5, 1957. Dipper dredge Atlas 504 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 removed about 3,900 cubic yards of material from Salt Creek by the end of the year, at a cost of $8,863. The total costs for the fiscal year were $8,863, for new work. 'Conditionat end of fiscal year. The existing project was about 95 percent completed. About 1911, local interests dredged Bayboro Harbor 14 feet deep, 450 feet wide, and 1,360 feet long with a connecting channel to Tampa Bay, but by 1912 the depth had shoaled to about 10 feet. Between 1924 and 1928, the City of St. Petersburg virtually completed the dredging of an entrance channel 19 feet deep and 250 feet wide leading westward from Tampa Bay to the city terminals, with a turning basin 20 feet deep, known as the Port of St. Petersburg, at the inner end of the channel. Dredging spoil was used to make additional land around the basin, on which the wharves, transit sheds, and other terminal facilities were constructed. The United States completed the entrance channel to full depth of 19 feet and the Port of St. Petersburg to full depth of 21 feet during March and April 1931. During December 1929 and January 1930, the Point Pinellas Channel was dredged 14 feet deep, 200 feet wide, and 6,200 feet long. The 20-foot-depth entrance channel leading northerly from lower Tampa Bay was dredged between November 1938 and September 1939. In 1943, under authority of section 3 of the River and Harbor Act approved October 17, 1940, Salt Creek was dredged 10 feet deep and from 50 to 75 feet wide for about 1,500 feet from its mouth. Under authority of section 3 of the River and Harbor Act approved March 2, 1945, a 12-foot basin was dredged in Bayboro Harbor, about 1,300 feet long on the south and 700 feet on the north, and about 800 feet wide. The work was done during September 1945 as a war-emergency measure. The controlling mean low water depths when last ascertained were as follows: 20.5 feet for a width of 200 feet in the 20-foot channel leading northward from Tampa Bay, in April 1940; 19 feet for a width of 225 feet in the 19-foot entrance channel and 21.1 feet throughout the Port of St. Petersburg basin, in February 1943; 14.5 feet for a width of 200 feet in Point Pinellas Channel, in May 1938; and 10.5 feet in Bayboro Harbor, in August 1956. The costs under the existing project have been $197,753 for new work, and $49,165 for maintenance, a total of $246,918.

ANCLOTE RIVER, FLA. Location. Anclote River rises in the western part of the peninsula of Florida and flows southwesterly, emptying into the Gulf of Mexico about 38 miles north of the entrance to Tampa Bay. (See U. S. Coast and Geodetic Survey Chart No. 1257.) Existing project. This provides for a channel 9 feet deep at mean low water and 100 feet wide, with width increased at entrance and at bends, from the Gulf of Mexico to and including a turning basin of irregular shape, 850 feet long and 300 feet in maximum width, at Tarpon Springs. The length of the section included in the project is about 8.5 miles. The mean range of tide is about 2 feet at the entrance, 1.5 feet at the mouth of the river, and 2 feet at Tarpon Springs. The extreme range is about 5.5 feet at the entrance. Strong south- westerly winds raise the water level about 1 foot; strong northerly or northeasterly winds, which occur mostly during the winter, lower the water level about 1.5 feet. The estimate of cost for new work is $246,000 (July 1956). There has been no maintenance of the project in the past 5 years. The current approved estimate is $5,000 (1950). The existing project was authorized by the following: Acts Work authorized Documents Mar. 3, 1899 A channel 6 feet deep and 100 feet wide to Sponge Har- H.

The River and Harbor Act of March 2, 1945, imposed the conditions that local interests furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas for the initial work and for subsequent maintenance as required; construct additional bulkhead wharves, as required and approved by the Chief of Engineers and the Secretary of War; and hold and save the United States free from claims for damages resulting from the improvement. A resolu- tion adopted June 4, 1946, by the city of Tarpon Springs, agreeing to assume responsibility for complying with the above require- ments, was accepted by the Chief of Engineers on July 11, 1946, as satisfactory assurance of compliance. The city of Tarpon Springs has furnished all but two parcels of land required for the enlarged turning basin. All prior requirements have been fully complied with. Terminal facilities. These consist of the Sponge Exchange marginal wharf 330 feet long, three fish wharves, three petroleum- products wharves, and several small marine ways at Tarpon Springs, and numerous privately owned boathouses, piers, and wharves along the river. Highway connections only are provided. The Sponge Exchange wharf is considered inadequate for the 506 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 sponge fleet; other terminals are considered adequate for the existing commerce. Operations and results during fiscal year. New work: A de- sign memorandum on the project was completed September 14, 1956. Completion of plans and specifications was delayed pending receipt of additional parcels of right-of-way. Hired labor, surveys, and reports cost $5,383. The total cost for the fiscal year was $5,383 for new work. Condition at end of fiscal year. The existing project was about 86 percent completed. A channel 100 feet wide and 6 feet deep from the Gulf of Mexico to Sponge Harbor and thence 4 feet deep to Tarpon Springs was provided betwen May 1900 and November 1910. The 6-foot channel was extended to Tarpon Springs, with a turning basin 200 feet wide and 500 feet long at that locality, between December 1928 and May 1929. The channel was deepened to 9 feet from the Gulf of Mexico to the lower end of the turning basin at Tarpon Springs between September 1936 and September 1938. In May 1948, the controlling depth from the entrance to Tarpon Springs was 9.5 feet except for a spot shoal with a limiting depth of 7.6 feet about opposite Beacon 9, and a depth of 6 feet was available in the existing 6-foot-depth turning basin. The work remaining to be done to complete the project is extension and enlargement of the channel upstream to form a new turning basin of irregular shape, 9 feet deep, 850 feet long, and 300 feet in maximum width at Tarpon Springs. The costs under the existing project have been $183,810 for new work and $88,957 for maintenance, a total of $272,767.

REMOVING THE WATER HYACINTH FROM NAVIGABLE WATERS IN THE STATE OF FLORIDA Location. The water hyacinth is found in the fresh-water streams and lakes in various parts of the district. Existing project. This provides for the destruction or removal of the water hyacinth in the navigable waters of the State so far as they constitute an obstruction to commerce, using any mechanical, chemical, or other means not injurious to cattle, and the use of log booms to close sloughs and backwaters as an auxiliary means. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 507 No estimate of the final cost of the work has been made. The average annual maintenance cost during the past 5 years was $59,146.

A chemical for spraying was tested in August and September 1900; spraying was begun in November 1902 but was discontinued in February 1906 because of the injurious effect on cattle. Subse- quent operations through the fiscal year 1938 consisted chiefly of breaking up jams and drifting, except from November 1909 to February 1918, when an elevator was used to either place the plants on shore or to form them in deep piles that could be carried away by the currents. Later operations, through April 1948, have consisted principally of construction of temporary and per- manent traps at strategic points, and shredding with cutterboats. Spraying with a new chemical, which is not injurious to cattle or fish, was begun in March 1948, to supplement other methods, and has proven to be highly effective. Since that date, spraying has gradually become the principal method of destruction, supple- mented by previously used methods.

S. ARMY, 1957 18. CENTRAL AND SOUTHERN FLORIDA Location. The project area includes the Upper St. Johns River and related areas, the Kissimmee River basin and related areas, and the Lake Okeechobee-Everglades-east coast areas, all in central and southern Florida. (See U. S. Coast and Geodetic Survey Charts Nos. 473, 1245, 1246, 1247, 1248, and 1289 and "Florida Everglades Drainage District," U. S. Geological surveys quadrangle sheets of the area, and Soil Conservation Service maps Nos. 1524 to 1561, July 1946.) The Upper St. Johns River and related areas lie principally in Orange, Brevard, Indian River, and St. Lucie Counties. The Kissimmee River basin and related areas begin in Orange County and extend southerly through Osceola, Polk, Highlands, Okeechobee, and Glades Counties. Lake Okeechobee and its regulatory outlets lie in Palm Beach, Martin, Okeechobee, Glades, Hendry, and Lee Counties. St. Lucie Canal flows from the lake to the Atlantic Ocean; the Caloosahatchee River, from the lake to the Gulf of Mexico. The lower east coast region embraces the populous urban and agricultural areas in Palm Beach, Broward, and Dade Counties. The region lies along the coast from the St. Lucie Canal south to near the tip of the State, and extends 9 to 20 miles inland. The conservation areas lie in Palm Beach, Broward, and Dade Counties west of the lower east coast region, and include 1,344 square miles of the Everglades suitable only for water and wildlife conservation. Lake Okeechobee agricultural area lies south of the lake, mostly in western Palm Beach County, but including part of Hendry County. The area embraces 1,130 square miles of muck and peat land which is suited for long-term agricultural use. Previous projects. Previous projects consist of completed works for control of Lake Okeechobee included in and constructed under the navigation project for Okeechobee Waterway, Florida (formerly Caloosahatchee River and Lake Okeechobee drainage areas, Florida), and under provisions of River and Harbor Acts, approved July 3, 1930, and August 30, 1935. For further infor- mation see pages 877-882, Annual Report for 1948, and page 785, Annual Report for 1949. Existing project. This provides for modification and expansion of the previous project to include the comprehensive plan for flood 10 Inaddition, $40,000 to be contributed by local interests. 11In addition, $1,000 were expended from contributed funds. 12Includes $6,532 expended on special report on local cooperation. 13Includes $12,217 expended on special report on economic analysis. 14The estimate of $8,000 represents the extent to which the Federal Government is authorized to par- ticipate and is one-third the cost chargeable to publicly owned shore frontage. The estimated cost to local interests is $242,500. 15Authorizing Act limits Federal participation to $140,000. In addition, $280,000 is to be contributed by local interests. 16Authorized by River and Harbor Act approved September 3, 1954, but due to no activity in the fiscal year and policy on brevity, details of project have not been reported. 17The estimate of $35,000 represents the total estimated cost applicable to Federally-owned shore and one-third of the cost applicable to publically owned shore. The estimated cost to local interests is $683,000. 18In addition, $21,960 was expended from contributed funds. 19Included with total costs to date for the project. 20In addition, $1,672 was expended from contributed funds. 21Curtailment of existing project recommended in H.

Upon completion, local interests are to assume maintenance and operation of all works in c and d above, except the gated spillways referred to in c and features (7) through (10) in d, which works will be operated and maintained by the United States. In addition, the project includes maintenance (since July 1, 1950) of control works completed with river and harbor funds under the previous navigation project for Okeechobee Waterway, Fla. (formerly Caloosahatchee River and Lake Okeechobee drainage areas, Florida), as follows: (a) A levee about 67.8 miles long from Fisheating Creek to St. Lucie Canal, following in general the south shore of the lake, and a northshore levee 15.74 miles long (those levees are to be improved and enlarged under the existing project); (b) 4 auxiliary floodway channels extending into Lake Okeechobee at or near Liberty Point, mouth of Fisheating Creek, mouth of Kissimmee River, and mouth of Taylor Creek; (c) collection and evaluation of meteorological data; and (d) opera- tion and care of spillways at the St. Lucie and Ortona locks, 5 FLOOD CONTROL-JACKSONVILLE, FLA., DISTRICT 513 hurricane gates on Lake Okeechobee, 16 drainage culverts through the west-, south-, and east-shore levees and 4 on the north shore of Lake Okeechobee, 16 drainage spillways along the St. Lucie Canal, and an intercommunicating radio-telephone network of 8 stations.

They are constructed of concrete with steel sector gates, and have no lift. Hurricane gate No. 6 has an auxiliary culvert spillway with automatic control. Lake Okeechobee is maintained, so far as possible, between elevation 13 and 15 feet, mean sea level. The estimate of cost for new work (spring 1957, on interim basis) is $228,455,000 Federal funds and $37,845,000 contributed funds, exclusive of river and harbor funds expended on previous projects. Local interests costs in reviewing plans and specifica- tions are expected to be $230,000. In addition, the estimated cost to local interests of lands, rights-of-way, and relocations is $34,700,000 (November 1956). The average annual maintenance cost during the past 5 years was $132,474. The existing project was authorized by the following: Acts Work authorized Documents June 30, 1948 The first phase of the comprehensive plan for flood H. Doc. 643, 80th Cong., 2d sess. control and other purposes, and authorized to be (contains latest published maps). appropriated $16,300,000 for partial accomplish- ment of the first phase. May 17, 1950 Authorized to be appropriated an additional $20 Specified in act. million for continuation of the first phase. Sept. 3, 1954 Modification and expansion of authorization for the H. Doc.643, 80th Cong., 2d sess. comprehensive plan given by the Flood Control Act of June 30, 1948, as amended, to include entire comprehensive plan of improvement as recom- mended by the Chief of Engineers in House Docu- ment 643, 80th Cong., 2d sess., and authorized'to be appropriated an additional $7,000,000 for partial accomplishment of said plan. Local cooperation. The Flood Control Act approved June 30, 1948 (H. Doc. 643, 80th Cong., 2d sess.), imposed the conditions that local interests shall provide all lands, easements, and right- of-way; make a cash contribution of 15 percent of the estimated construction cost for each part of the work prior to its initiation (with the provision that the total cash contribution for the entire comprehensive plan shall not exceed $29,152,000); and furnish assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from damages due to the 514 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1951 construction and operation of the works and that they will maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of the Army, except the levees, channels, locks, and control works of the St. Lucie Canal, Lake Okeechobee, and Caloosahatchee River, and the main spillways of the conservation areas. In May 1949, the Florida State legislature passed legislation providing for creation of districts for flood control, reclamation, conservation, and allied purposes to cooperate with the United States on Federal projects; for creation of the Central and Southern Florida Flood Control District, and for consolidation of the former Everglades Drainage District with that district; and for other measures necessary for full compliance with all require- ments of local cooperation. A resolution adopted August 1, 1949, by the Central and Southern Florida Flood Control District, as- suming full responsibility for compliance with the requirements of local cooperation as set forth in the project document, was accepted by the Chief of Engineers on November 25, 1949, as satisfactory assurance of compliance. The Flood Control District has furnished right-of-way and other interest in land, and has contributed the required 15 percent of the estimated construction cost for each feature of the project, when and as requested by the district engineer. In response to a request of local interests on June 10, 1950, urging construction of the eastern boundary levees of the conservation area to an intermediate grade, the Chief of Engineers outlined a general policy permitting such construction, provided that local interests agree to maintain the levees at those heights pending completion to full grade. The Central and Southern Florida Flood Control District has agreed to assume full responsibility for maintenance of the levees so constructed. The Flood Control District has accepted responsibility for operation and maintenance of features as they are completed and formally transferred to them. (See par. "Condition at end of fiscal year" for features and transfer dates.) Those features are periodically inspected by District Engineers' Staff and the Flood Control District advised of maintenance needed. The Flood Control District was authorized, and obtained Congressional approval to advance $2,900,000 to accelerate the construction program beginning in the fiscal year 1955, and to receive credit for that amount on the total cash contribution required of $29,152,000. The Flood Control Act approved September 3, 1954, imposed the requirements that the conditions of local cooperation for the authorized first phase heretofore approved by said flood-control act shall apply to that authorized first phase, but for all work over and beyond that previous authorization such conditions shall apply on an interim basis only until they shall be modified as deemed appropriate by the Congress, based on recommendations to be submitted at the earliest practicable date by the Chief of Engineers, through the Bureau of the Budget to the Congress: provided, that whatever conditions of local cooperation are established by Congress as the result of such recommendations FLOOD CONTROL-JACKSONVILLE, FLA., DISTRICT 515 shall be retroactive to any units of the comprehensive plan authorized in this act which may be started prior to establishment of the exact conditions of local cooperation. The Flood Control District's resolution adopted September 15, 1954, agreeing to all the conditions imposed by the 1954 Act, has been accepted by the District Engineer as satisfactory assurance of compliance. The special report (Nov. 1956) required by the 1954 act has been accepted by the Bureau of the Budget and transmitted to the Congress. Contribution on construction of works authorized by the 1954 act has been made on an interim basis pending Con- gressional approval of modified conditions set forth in the special report. In addition to the local cooperation requirements for the author- ized project, local interests propose additional and related works in the form of a secondary system of channels to further serve the land developer, who in turn will construct the necessary laterals, field ditches, farm levees and pump units, all of which will permit maximum benefits from the major flood-control works as provided by the project. The Flood Control District, with the cooperation of local interests, has completed plans of secondary works in the Everglades Agricultural Area in Dade County, and is now plan- ning other areas. The District estimates that secondary works for the total project will exceed $80,000,000. The Flood Control District proposes to provide the necessary rights-of-way for the secondary channel system. The land de- veloper, either an organized subdrainage district or individual landowner, will bear the cost of construction of the secondary channels and all cost for development of the farm protective works. In 1950 the Flood Control District adopted a program of emergency construction of new works or improvements of existing works necessary to prevent flood damages in areas where the con- struction of the works of the flood control program would be years in being realized. This program is estimated by the Flood Control District to cost $2,000,000, of which about half of that amount has been spent. Operations and results during fiscal year.

Corps of Engineers. Lake Okeechobee stages varied between elevation 13.9 and 10.1 feet above mean sea level during fiscal year 1957. Under the approved regulation schedule lake stages are maintained between elevations 15.5 and 12.5 feet insofar as possible. Severe drought conditions during 1955 and 1956, however, caused the lake to recede to the lowest stage of record during August 1956. Navigation on the Okeecho- bee Waterway was curtailed during the period from July through October when the lake stage was below elevation 12.56 feet which is required to provide project depth of 8 feet. Although the lake reached the lowest stage of record, water was available to supply most of the irrigation needs in the developed agricultural area southeast of the lake. b. Central and Southern FloridaFlood Control District. Struc- tures and pumping stations constructed as part of the Central and Southern Florida Flood Control Project were operated by the Flood Control District. Following heavy rains on January 21, 1956 when the average precipitation over Lake Okeechobee agri- cultural area was about 6 inches, pumping stations 2 and 5A were operated to remove about 37,000 acre-feet from the agricultural area. Those pumping stations and related project works pre- vented $7,500,000 damage during that storm. Following heavy showers in January, February, and April, canals 2, 9, 11, 12, and 13, and related project works prevented flooding which would have caused damages of about $350,000 in the East Coast area. Condition at end of fiscal year. The project was about 16 percent completed. The following features were constructed under previous proj- ects for the Okeechobee Waterway, Fla., and are maintained under this project: A levee 67.8 miles long from Fisheating Creek to St. Lucie Canal, following in general the south shore of the lake, January 1932 to March 1936; a north-shore levee 15.74 miles long, July 1936 to February 1938; the spillway at Ortona lock, Novem- ber 1934 to August 1937; four auxiliary floodway channels ex- tending into Lake Okeechobee at or near Liberty Point, mouth of 518 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Fisheating Creek, mouth of Kissimmee River, and mouth of Taylor Creek, June 1932 to February 1938; five hurricane gates through the levees at entrance to canals at Clewiston, Lake Harbor, South Bay, Canal Point, and Taylor Creek, November 1933 to December 1936; 16 drainage culverts through the west-, south-, and east-shore levees, and four similar culverts through the north-shore levee, December 1933 to December 1936; and 16 drainage spillways at drainage openings along the banks of the St. Lucie Canal, November 1934 to September 1935.

Adopted by the River and Harbor Acts approved May 23, 1828, and July 25, 1912, for the section between Mobile Bay and Mississippi Sound. For further details, see page 906, Annual Report for 1930. Existing project. This provides for a waterway 12 feet deep and 125 feet wide at mean low water from Apalachee Bay, Fla., to Mobile Bay, Ala., and 12 feet deep and 150 feet wide from Mobile Bay, Ala., to the Rigolets, La. (Lake Borgne Light No. 41), and for a tributary channel (the Gulf County Canal), 9 feet deep, 100 feet wide, and about 6 miles long connecting the Intra- coastal Waterway at White City, Fla., with St. Joseph Bay. Length of the waterway between the 12-foot depth contours in Apalachee Bay and Lake Borgne Light No. 41 at the Rigolets is 379 miles. The estimated cost of new work (1957) is $5,945,000, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $147,013. That portion of the project consisting of construction of a movable span in the Georgia, Florida, and Alabama Railroad bridge crossing the Ochlockonee River, Fla., as authorized by the River and Harbor Act of March 2, 1945, is inactive and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1951, and was estimated to be $33,000. The portion of the project from Apalachicola Bay to St. Marks River, Fla., via St. George Sound, Carrabelle, Crooked and Ochlockonee Rivers and Ochlockonee and Apalachee Bays, is to be restudied and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1955, and was estimated to be $760,000.

APALACHICOLA, CHATTAHOOCHEE, AND FLINT RIVERS, GA. AND FLA. Location. The Apalachicola River is formed at the southwest corner of the State of Georgia by the junction of the Chattahoochee and Flint Rivers and flows south 108 miles, emptying into Apa- lachicola Bay. The Florida River enters the Apalachicola River from the east at mile 45.4 and the River Styx also enters from the east at mile 36.7, and the Chipola River enters from the west at mile 28.2. (See U. S. Coast and Geodetic Survey Chart No. 1262.) The Chattahoochee River, 418 miles long, rises in northeast Georgia and flows southwesterly to West Point, and thence south- erly to join the Flint River at the southwest corner of Georgia, forming the Apalachicola River. (See U. S. Geological Survey mans for northwest Georgia.) The Flint River, 330 miles long, rises in west central Georgia, flows generally southeasterly to Albany, and thence southwest to the southwest corner of the State, where it joins the Chatta- hoochee River to form the Apalachicola River. (See U. S. Geological Survey maps for southwest Georgia.) Previous projects. Expenditures on the Apalachicola River were made between 1828 and 1831, but apparently under no definite project. In 1835 and 1836, appropriations were made for the Chipola River. For further details, see page 690, Annual Report for 1938. Projects for the Apalachicola River were adopted by the River and Harbor Acts of June 23, 1874, June 13, 1902, January 6, 1934, and June 20, 1938. For further details, see the existing project for Apalachicola River, page 568, Annual Report for 1944. Projects for Flint River, Ga., were adopted by River and Harbor Acts of June 23, 1874, and June 14, 1880. For further details, see the existing project for Flint River, Ga., page 570, Annual Report for 1944. The River and Harbor Act of July 13, 1892, made an appropria- tion for the section of the Chattahoochee River between West Point and Franklin, Ga., and appropriations therefor were con- tinued until 1899, when they were discontinued. For further 528 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 details, see page 1834, Annual Report for 1915, and page 696, Annual Report for 1938. The River and Harbor Act of June 23, 1874, adopted the project for the Chattahoochee River from its mouth to Columbus, Ga. For further details, see existing project for that river on page 572, Annual Report for 1944. For total cost and expenditures on all previous projects, see cost and financial summary for the Apalachicola, Chattahoochee, and Flint Rivers, Ga. and Fla., on page 812 of the Annual Report for 1945. Existing project. Prior to the River and Harbor Act ap- proved March 2, 1945, the existing project for the Apalachicola River provided for a channel therein 6 feet deep at low water and 100 feet wide, to be secured by removing snags and over- hanging trees and by widening and straightening Moccasin Slough, for a channel 5 feet deep and 60 feet wide through the Cutoff, Lee Slough, and lower Chipola River, together with snag- ging and dredging to a depth of 6 feet the lower 2,500 feet of Styx River and improving of Florida River by dredging a new outlet 6 feet deep, 80 feet wide, and about 600 feet downstream of its present mouth; for the Chattahoochee River, a channel 4 feet deep at low water and 100 feet wide from the mouth to Columbus, Ga., 164 miles, by removing timber obstructions, dredging, contraction works, and shore protection; and for the Flint River, a channel 100 feet wide and 3 feet deep at extreme low water from the mouth to Albany, 103 miles, to be obtained by dredging, rock excavation, contraction works, and removal of snags, together with a channel for light-draft steamers at moderate stages from Albany to Montezuma, 79 miles, to be obtained by removing loose rocks, snags, and overhanging trees. The River and Harbor Act of March 2, 1945, approved the general plan presented in House Document 342, 76th Congress, 1st session, for the full development of the Apalachicola, Chatta- hoochee, and Flint River system in the combined interest of navigation and power, and authorized certain works for the initiation and partial accomplishment of that plan. Prior to its initiation, that phase of development was modified by the River and Harbor Act of July 24, 1946. The River and Harbor Act of July 24, 1946, approved modifi- cation of the general plan in accordance with House Document 300, 80th Congress, 1st session, to include improvements proposed by the Chief of Engineers in lieu of the corresponding works of the plan presented in House Document 342, 76th Congress, 1st session, and authorized for the initiation and partial ac- complishment of the modified plan the construction of Buford multipurpose reservoir, Fort Benning lock and dam, and the Upper Columbia and Jim Woodruff, formerly Junction, multiple- purpose development, and supplemental channel work to provide a channel depth of 9 feet for a minimum width of 100 feet in the Apalachicola River, to Columbus, Ga., on the Chattahoochee River, 268 miles, and to Bainbridge, Ga., on the Flint River, 29 miles above its junction with the Chattahoochee River. The Committee on Public Works of the House of Representatives, by RIVERS AND HARBORS-MOBILE, ALA., DISTRICT 529 resolution adopted May 19, 1953, approved the plan as proposed by the Chief of Engineers for a low dam at the Columbia site and a high dam at the Fort Gaines site in lieu of a high dam at the Upper Columbia site and a low dam at the Fort Benning site.

The estimated cost for new work, revised in 1957, is $188,- 201,000, including $1,257,000 for dredging in the Apalachicola River, and exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $22,080. The mean range of tide at the mouth of the Apalachicola River is 1.6 feet; at the point where the river is formed the variation between low and high water is about 37 feet. On the Chatta- hoochee River, the variation between average low and high water is about 20 feet, and the extreme fluctuation is 65.3 feet at Eufaula. On the Flint River, the extreme fluctuation of stage due to floods is 40 feet, while the average variation between low and high water is about 21.5 feet. Local cooperation. This provides that local interests agree to furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas, as and when required, for provision and maintenance of the channel in Apalachicola River below Jim Woodruff Dam, to maintain and operate at their expense all utility and highway facilities which are relocated or otherwise altered as a part of the improvement, to provide suitable public-terminal facilities open to all on equal terms, 530 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 and to hold and save the United States free from damages which might arise from the construction of the improvement. In regard to the Jim Woodruff lock and dam and the Apalachi- cola River below the dam, appropriate State, county, and other responsible local agencies concerned have furnished satisfactory assurances that the conditions of local cooperation will be met as and when required. These conditions are being fulfilled. Easements for rights-of-way and spoil-disposal areas have been provided as required along the Apalachicola River, and adequate terminals are being constructed by local interests at Bainbridge, Ga., on the Flint River. No local cooperation is required in connection with the Buford Dam. The conditions of local cooperation applicable to the Fort Gaines development require that local interests maintain and operate, at their expense, relocated or altered utility and high- way facilities, and provide suitable public-terminal facilities. This matter has been discussed with appropriate local agencies and organizations, and their willingness and ability to comply with all requirements of local cooperation have been indicated. No action has been taken in the matter of local cooperation with respect to the Columbia lock and dam. Terminal facilities. At Apalachicola, Fla., the facilities consist of several pile-and-timber wharves. There is a private wharf with spur line rail connection at Chattahoochee, Fla., which is used mainly for handling sand and gravel. At Bainbridge, Ga., on the Flint River, there is a public wharf with concrete deck for handling general cargo, and a riverside bulk storage terminal for petroleum products. The facilities on the Chattahoochee River consist of natural landings at Columbus, Ga., and Eufaula, Ala., and a masonry marginal landing at Columbus. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work per- formed under contract in the Apalachicola River channel was as follows: The contractor's dredge Greenville, operating in the channel from July 6 to December 26, 1956, and from January 1 to March 11, 1957, removed 1,243,610 cubic yards of earth material and 2,763 cubic yards of rock material; the contractor's dredge Plaquemines, operating in the channel from August 11, 1956 to January 4, 1957, and from January 9 to March 10, 1957, removed 466,097 cubic yards of earth material; the contractor's dredge Chickasaw, operating in the channel from September 1 to Decem- ber 26, 1956, January 1 to March 26, 1957, and June 10 to June 30, 1957, removed 1,004,142 cubic yards of earth material and 28,023 cubic yards of rock material; and, during the period July 16 to December 31, 1956, the contractor cleared 19.4 acres, all at a cost of $887,738 for dredging and clearing.

Fly Creek (Volanta Bayou) is a small stream about 4.5 miles long rising in Baldwin County, Ala., 3 miles east of the town of Fairhope, from whence it flows northerly, thence westerly and southerly, to form an estuary on the eastern shore of Mobile Bay just north of Fairhope and about 13 miles southeast of Mobile, Ala. (See U. S. Coast and Geodetic Survey Chart No. 1266.) Existing project. This provides for a channel 6 feet deep, 80 feet wide, and about 1,650 feet long, from the 6-foot depth in Mobile Bay to a turning basin of the same depth, 100 feet wide and 350 feet long, in Fly Creek. The mean tidal range in the vicinity of the project is about 1.3 feet, and the extreme, except during storms, is 3.5 feet. The approved estimated cost for new work, revised in 1957, was $26,000. The latest (1957) approved estimate for annual cost of main- tenance is $2,000. The existing project was authorized by the River and Harbor Act of May 17, 1950 (H. Doc. 194, 81st Cong., 1st sess.). The project document contains the latest published map. Local cooperation. Local interests are required to give as- surances satisfactory to the Secretary of the Army that they will comply with conditions of local cooperation prescribed as follows: (a) Provide without cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas necessary for the construc- tion and subsequent maintenance of the project; (b) hold and save the United States free from damages due to the construction and subsequent maintenance of the works; (c) provide at their own expense necessary mooring facilities, including a public land- ing with suitable supply facilities, parking areas, and an all- weather access road to the harbor facilities, and maintain the existing timber jetty at the mouth of the creek; and (d) establish a competent and properly constituted public body empowered to regulate the use, growth, and free development of the harbor facilities with the understanding that all such facilities shall be open to all on equal terms. By resolution adopted December 17, 1956, the City of Fairhope, representing local interests, agreed to comply with the prescribed conditions of local cooperation. Terminal facilities. The Fairhope Yacht Club has facilities for small recreational craft on both banks near the mouth of the creek, consisting of a small pile-and-timber service wharf, several sheet-metal boat sheds, boat slips, and other mooring facilities. There is also a marginal timber wharf and shed for commercial fishing boats on the right bank of the creek immediately above the first bend. Operations and results during fiscal year. A contract for construction of the project was awarded in June 1957. The total cost for the fiscal year was $2,587, all charged to new work.

ALABAMA-COOSA RIVERS, ALA. AND GA. Location. The Alabama River is formed 18 miles above Mont- gomery, Ala., by the junction of the Coosa and Tallapoosa Rivers. Thence it flows southwesterly through Alabama 318 miles, and RIVERS AND HARBORS-MOBILE, ALA., DISTRICT 547 unites with the Tombigbee River about 45 miles north of Mobile, in southwestern Alabama, to form the Mobile River. (See U. S. Geological Survey maps for central and southwest Alabama.) The Coosa River is formed at Rome, Ga., in northwest Georgia, by the junction of the Oostanaula and Etowah Rivers, which have their sources in southeastern Tennessee and northern Georgia. From Rome the Coosa River flows southwesterly through Georgia and Alabama 286 miles, and unites with the Tallapoosa River near Montgomery, Ala., at about the center of the State, to form the Alabama River. (See U. S. Geological Survey maps for northeast Alabama, southeast Tennessee, and northwest Georgia.) Previous projects. Projects for Alabama River were adopted by the River and Harbor Acts of June 18, 1878; July 13, 1892; March 3, 1905; and June 25, 1910. For further details, see page 1837, Annual Report for 1915; page 725, Annual Report for 1938; and paragraph "Existing project", page 592, Annual Report for 1944. Projects for the Coosa River were adopted by the River and Harbor Acts of August 14, 1876; September 18, 1890; July 13, 1892; June 25, 1910; and June 26, 1934. For further details of previous projects, see page 1837, Annual Report for 1915; page 728, Annual Report for 1938; and paragraph "Existing project", page 594, Annual Report for 1944. Existing project. This provides for the initial and ultimate development of the Alabama-Coosa Rivers and tributaries for navigation, flood control, power, and other purposes, substantially in accordance with plans being prepared by the Chief of Engineers, with such modifications thereof from time to time as in the- dis- cretion of the Secretary of the Army and the Chief of Engineers may be advisable for the purpose of increasing the development of hydroelectric power; for the initiation and accomplishment of the ultimate plan, it authorizes appropriations in such amounts as Congress may from time to time determine to be advisable, the total of such appropriations not to exceed $60 million. Public Law 436, 83d Congress, approved June 28, 1954, sus- pended authorization of the comprehensive plan, insofar as it provides for the development of the Coosa River, to permit non- Federal interests to develop the Coosa River by construction of a series of dams in accordance with the conditions of a license, if issued, pursuant to the Federal Power Act and in accordance with certain other provisions and requirements of the aforementioned Public Law. The initial phase of the ultimate development of the Alabama River provides for the construction of Jones Bluff and Millers Ferry multiple-purpose improvements, Claiborne lock and dam, and supplemental channel work to provide a channel depth of 9 feet for navigation from the mouth of the Alabama River to Montgomery. The variation between average high and low water is 40.4 feet. The extreme variation is 58 feet at Montgomery. 548 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The estimated cost for new work on the Alabama River, revised in 1957, is $121,570,000, consisting of $119,900,000 for multiple- purpose structures, and $1,670,000 for supplemental channel im- provement, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $7,329. The existing project was adopted by the River and Harbor Act of March 2, 1945 (H. Doc. 414, 77th Congress, 1st Sess.). The aforecited document contains the latest published map of the Alabama-Coosa Rivers and tributaries. Local cooperation. The conditions of cooperation required are to be determined as the formulation of plans for development of the project progresses. No action in the matter of local cooperation has been initiated. Terminal facilities. On the east bank at Montgomery, a natural landing connects with the city streets. The Wofford Oil Co. has a small wharf about 10 miles below Montgomery equipped for handling petroleum products. There are also various natural landings along the river. These facilities and natural landings on the Alabama River are considered adequate for the existing commerce. Operationsand results during fiscal year. New work: A con- tinuation of review of plans for the development of the Coosa River, submitted by non-Federal interests pursuant to Public Law 436, 83d Congress, cost $4,515. No new work was performed toward development of the Alabama River. Maintenance: Miscellaneous surveys and investigations cost $358. RIVERS AND HARBORS-MOBILE, ALA., DISTRICT 549 The total cost for the fiscal year was $4,873, of which $4,515 was charged to new work, and $358 to maintenance. Condition at end of fiscal year. No construction has been per- formed on the existing project as authorized by the River and Harbor Act of March 2, 1945. Site selection and other pre- liminary planning studies have been initiated. Maintenance operations on the Alabama River, since authorization of the exist- ing project, have been limited mainly to periodic dredging to re- store the 4-foot open channel depth from the mouth to Wetumpka as provided for under previous projects. Maintenance operations on the Coosa River, which were discontinued in 1950, consisted mainly of the care of Government property at locks and dams which had been constructed under the previous projects. Those locks and dams have been inoperative for some years and no longer serve any useful purpose. Inspections of the lower Alabama River in 1955 indicated a controlling depth of 4 feet from the mouth to Claiborne. The controlling depths, ascertained in 1938, were as follows: Mouth to Selma, 4 feet; Selma to Montgomery, 3.5 feet; and Montgomery to Wetumpka, 3 feet. Boats drawing 3 feet can usually operate throughout the year; greater depths are usually available from November to June. On the Coosa River, the controlling depth on several of the bars, as ascertained in 1938, was 2.5 feet, and in other reaches of the river, 3 to 4 feet. Since all existing locks on the river are inoperative, through navigation is impossible. The cost under the existing project to June 30, 1957, was $1,787,862, of which $1,665,094 was for new work (preliminary planning studies), $103,505 for maintenance of existing channel in Alabama River (4-foot project), and $19,263 for operating and Cost and financial statement Fiscal year ending June 30 Total to June 30, 1957 1 1953 1954 1955 1956 1957 New work: Appropriated $200,000 ...-------- -$41, 000 -$30, 615 $15, 000 2 $1, 668,985 Cost---------------- 784 101, 38,614 8,929 6,594 515 $4, 11,665, 094 Maintenance: Appropriated-------...... 5, 886 -826 ------------........ 31, 587 -122, 768 Cost----------------- 5, 886 -826 ------------.....358 31,229 122,768 1Exclusive of $3,692,483 for new work and $2,978,050 for maintenance on previous projects. 2 Includes $1,012,985 allotted for planning studies on Howells Mill Shoals Dam on Coosa River and $15,000 allotted for review of plans for development of Coosa River submitted by non-Federal interest pursuant to Public Law 436, 83d Congress. 8Includes $1,012,985 applied to new work on Howell Mill Shoals dam on Coosa River, and $11,109 ex- pended during fiscal years 1956-57 on review of plans submitted by non-Federal interests pursuant to Public aw 436, 83d Congress.

BLACK WARRIOR, WARRIOR, AND TOMBIGBEE RIVERS, ALA. Location. The Black Warrior and Warrior Rivers, a single stream, rise in northern Alabama above Birmingham and flow generally southwesterly to unite with the Tombigbee River at Demopolis, Ala. Thence, the Tombigbee flows south, uniting with the Alabama River to form the Mobile River 45 miles above the head of Mobile Bay. The distance by water from Mobile to the vicinity of Birmingham is about 415 miles. Previous projects. The original project for the improvement of Warrior River, now combined with Black Warrior and Tombig- bee Rivers, was adopted by Act of March 3, 1875. For further details, see page 1841, Annual Report for 1915, and page 732, Annual Report for 1938. Existing project. This provides essentially for a canalized channel with minimum depth of 9 feet and a width of 200 feet, where practicable, from the mouth of the Tombigbee River, 45 miles above Mobile, to the vicinity of Birmingham, via the Tom- bigbee and Warrior Rivers, to mile 447.6 on Sipsey Fork, mile 444.6 on Mulberry Fork, and mile 420.6 on Locust Fork, a total distance of 426.6 miles. The lift is accomplished by 12 locks and dams, 1 of the locks being a double-lift structure. The project provides also for operation and care of all locks and dams. The project was essentially completed in May 1915 when the last of the original series of 17 locks and dams was opened to navigation. Subsequent work has consisted mainly of modifica- tion and modernization of the project. The River and Harbor Act of March 3, 1909, granted discretionary authority to the Secretary of War to reconstruct any existing structure whenever reconstruction is absolutely essential to its efficient and economical maintenance and operation. The reconstruction may include such modification in plan and location as may be necessary to provide adequate facilities for existing navigation. Under that authority and subsequent authorizations, locks 10, 11, and 12 on the Warrior River were replaced by a single-lift lock at Tuscaloosa, Ala., which was opened to navigation in August 1939; lock 4 on the Tombigbee River, and locks 5, 6, and 7 on the Warrior River were replaced by a single-lift lock at Demopolis, Ala., which was opened to naviga- tion in August 1954; locks 8 and 9 on Warrior River will be re- placed by a single-lift lock (Warrior lock and dam) near Eutaw, Ala., which is now under construction; and locks 1, 2, and 3 on the Tombigbee River will be replaced by a single-lift lock (Jackson lock and dam) near Coffeeville, Ala., which also is under construction.

RIVERS AND HARBORS-MOBILE, ALA., DISTRICT 553 Tidal influence extends from Mobile 101.6 miles to lock 1, where the tidal effect is apparent only at low stages of river. At Mobile the mean and extreme tidal ranges are 1.5 and 3.6 feet, respec- tively. These are at times slightly increased by the effect of winds. The greatest fluctuation of river stages is at Demopolis, Ala., the maximum being 59.7 feet. The maximum fluctuations at other points are 40 feet at lock 1, 101.6 miles from Mobile; 57.8 feet at Tuscaloosa, 352.6 miles from Mobile; 13 feet at Birming- port, 409.6 miles from Mobile; and 27 feet at Cordova, 429.6 miles from Mobile. The ordinary fluctuations at these points are at lock 1, 20 feet; at Demopolis, 35 feet; at Tuscaloosa, 40 feet; at Birmingport, 4 feet; and at Cordova, 7 feet. The works of improvement have reduced the amount of fluctuations at different points by 3 to 10 feet. The estimated cost of new work, revised in 1957 is $72,205,000, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $1,001,536. Local cooperation. Fully complied with. Terminal facilities. Facilities comprising loading and transfer stations, wharves, etc., have been provided where required along this waterway. All are privately owned and operated except the terminals at Tuscaloosa, which are leased to a private company but serve the general public, and the terminals at miles 357.6 and 409.6 which are owned and operated by the Inland Waterways Corp., but also serve the general public. These terminals are considered adequate for the existing commerce. Operations and results during fiscal year.

Temporary facilities cost $20,909. The total cost for new work on Jackson lock and dam, during the fiscal year, was $682,625. Maintenance: The U. S. pipeline dredge Guthrie, operating in the Warrior and Tombigbee Rivers from July 1 to October 20, 1956 and April 15 to June 30, 1957, removed 1,924,401 cubic yards of material: the U. S. snagboat Montgomery, operating in the Warrior and Tombigbee Rivers from July 1 to December 31, 1956 and April 1 to June 30, 1957, removed 1,690 cubic yards of flood deposit from lock pits and approaches, 1,735 tons of rock from channel and approaches and 7,436 snags and obstructions; all at a cost of $345,270 for dredging and $122,002 for removal of obstructions. Rehabilitation of locks and dams cost $172,908. Miscellaneous surveys and investigations, supervision, administra- tion, and overhead cost $71,256. Operation and care of locks and dams cost $368,741. The total cost for the fiscal year was $8,642,056, of which $7,561,879 was for new work, and $1,080,177 'for maintenance, including operation and care of locks and dams. Condition at end of fiscal year. The existing project, com- menced in 1887, was essentially completed in 1915 when the last of the original series of 17 locks and dams was completed and opened to navigation. Since that time, 3 of the original locks and dams (10, 11, and 12) have been removed and replaced by the Tuscaloosa lock and dam which was completed in 1940, and 4 of the original locks and dams (4, 5, 6, and 7) have been removed and replaced by the Demopolis lock and dam on which all major construction work was completed during the fiscal year 1955. Construction work on the Warrior lock and dam (to replace existing locks and dams 8 and 9), was commenced in November 1954, and is about 82 percent completed. Planning studies on the Jackson lock and dam (to replace locks and dams 1, 2, and 3) were completed and construction commenced. Channel snagging and dredging have been completed, including dredging of a cutoff channel in 1938 through Sunflower Bend on the Tombigbee River. Construction of crest gates on dam 17 was completed in 1938. A depth of 9 feet and a minimum width of 100 feet are available at all times throughout the project, except at lock 1 where a depth of 9 feet over the lower miter sill is available about 91 percent of the time and a depth of 6.9 feet is available at extreme low tide. The work remaining to be done under present plans for modernization of the project consists of completing minor items of construction at the Demopolis lock and dam, and completing construction of the Warrior and Jackson locks and dams.

DAUPHIN ISLAND BAY, ALA. Location. This bay lies between Dauphin and Little Dauphin Islands, on the west side of the entrance to Mobile Bay, about 30 miles south of Mobile, Ala., and 55 miles west of Pensacola, Fla. (See U. S. Coast and Geodetic Survey Chart No. 1266.) Existing project. This provides for (1) a channel 7 feet deep and 150 feet wide from that depth in Mobile Bay to an anchorage basin of the same depth, 600 feet long and 500 feet wide, in the marsh just north of Fort Gaines on Dauphin Island; a channel 4 feet deep and 40 feet wide from the anchorage basin to the 3-foot hydrographic contour in Dauphin Island Bay; and for a jetty on the north side of entrance channel if the construction of such jetty is found necessary in order to prevent excessive shoaling in the channel; and (2) an anchorage basin 7 feet deep and 500 feet square at Dauphin Island village, with an entrance channel of like depth, 100 feet wide and about 8,300 feet long, extending to the 7-foot hydrographic contour in Mississippi Sound. The mean tidal range is 1.1 feet, and the extreme, except during storms, is about 4 feet. The estimated cost for new work, revised in 1957, is $295,100, of which $227,000 is for those features of the project located in 556 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the vicinity of Fort Gaines, and $68,100 for those features of the project located in the vicinity of Dauphin Island village. The estimate for the Fort Gaines channel ($227,000) includes $132,000 for bank stabilization works and a jetty, but does not include any estimate of cost for the 4- by 40-foot channel from the basin to the 3-foot contour in Dauphin Island Bay. That feature of the project has been eliminated in accordance with the desires of local interests since it is considered to be no longer necessary or warranted. The latest (1956) approved estimate for annual cost of maintenance of completed works is $7,500. The existing project was authorized by the River and Harbor Acts of March 2, 1945 (H. Doc. 333, 76th Cong., 1st sess.), and September 3, 1954 (H. Doc. 394, 82d Cong., 2d sess.). The documents contain the latest published maps. Local cooperation. For that portion of the project in the vicinity of Fort Gaines (Fort Gaines Channel), local interests are required to give assurances satisfactory to the Secretary of the Army that they will furnish, free of cost to the United States, necessary rights-of-way and spoil-disposal areas, when and as re- quired, for construction and subsequent maintenance of the project, and hold and save the United States free from claims for damages resulting from the improvement. No action has been taken in the matter of local cooperation in connection with the Fort Gaines Channel. For that portion of the project in the vicinity of Dauphin Island village (Village Channel), the requirements for local cooperation are the same as those for the Fort Gaines Channel, with the addi- tional provision that local interests are required to give satisfac- tory assurance that they will provide suitable landing facilities and access thereto, open to all on equal terms. These conditions have been complied with. Terminal facilities. The existing terminal facilities, all located at the village basin, consist of several privately owned pile-and- timber wharves for handling sea foods, one small pier for recrea- tional craft, and a public mooring slip. These facilities, with the proposed public wharf to be provided, are considered adequate for existing commerce. Operations and results during fiscal year. A general design memorandum on the Fort Gaines Channel was prepared and sub- mitted at a cost of $253. The total cost for the fiscal year was $253, all charged to new work.

Work remaining to be done to complete the project consists of dredging the Fort Gaines channel and basin, and constructing protective works proposed in connection therewith. The total cost under the existing project to June 30, 1957, was $69,570, all for new work. 15. PASCAGOULA HARBOR, MISS. Location. This harbor, located along the lower 6.8 miles of Pascagoula River and the lower 4 miles of Dog River, is in south- eastern Mississippi., about 61 miles by water west of Mobile Harbor, Ala., and about 44 miles east of Gulfport Harbor, Miss. (See U. S. Coast and Geodetic Survey Chart No. 1267.) Previous projects. Appropriations were made for Pascagoula River by the River and Harbor Acts of March 2, 1827, May 23, 1828, and August 30, 1852. The first definite project was adopted by the River and Harbor Act of June 14, 1880. Other proiects were adopted by the River and Harbor Acts of August 5, 1886, August 18, 1894, June 3, 1896, March 3, 1899, June 13, 1902, and June 25, 1910. For further details, see page 1843, Annual Report for 1915, and page 741, Annual Report for 1938. Existing project. This provides for a through channel of the maximum dimensions that can be secured by the expenditure of $283,000 but not exceeding 25 feet deep and 300 feet wide across the outer bar at Horn Island Pass, thence 22 feet deep and 225 feet wide to the railroad bridge at Pascagoula, thence 22 feet deep and 150 feet wide, increased at sharp bends, to a point on Dog River 4 miles above its mouth. The River and Harbor Act of May 17, 1950, modified the existing project to provide a cutoff channel, 12 feet deep and 125 feet wide, from State Highway 63 bridge over Dog River through Robertson and Bounds Lakes to mile 3.4 on Dog River, thence up Dog River to mile 4, in lieu of that part of the present proiect channel upstream of the State Highway 63 bridge (H. Doc. 188, 81st Cong., 1st sess.). The total length of the existing proiect is about 21.7 miles. Under ordinary conditions the mean tidal range is 13/4 feet and the extreme range is 33/t feet. The River and Harbor Act approved September 3, 1954. author- ized modification of the existing proiect in accordance with plans on file in the office of the Chief of Engineers. The plans for modification of the project are being further developed in ac- cordance with a resolution adopted August 16, 1950, by the Com- mittee on Public Works of the House of Representatives. which authorized and directed a review of reports on Pascagoula Harbor with a view to determining if it is advisable for the Federal Government to assume maintenance of the existing project of the Pascagoula Harbor, Miss., as modified by local interests. The project was modified by local interests in 1949, at their expense, 558 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 to provide a channel 35 feet deep and 325 feet wide through Horn Island Pass, 30 feet deep and 275 feet wide through Mississippi Sound and Pascagoula River to the Louisville and Nashville Rail- road bridge, and a turning basin 30 feet deep on the right bank of the river below the railroad bridge. The estimate of cost for new work, revised in 1957, is $1,260,000, including $958,000 for modification of the project as authorized by the River and Harbor Act approved September 3, 1954, but exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $69,574.

Allatoona Dam is on the Etowah River in Bartow County, Ga., about 48 miles upstream from Rome, Ga., about 5 miles due east of Cartersville, Ga., and about 2,000 feet down- stream from the mouth of Allatoona Creek. The reservoir extends about 27 miles up the Etowah River at maximum-power-pool elevation of 835 feet above mean sea level. Existing project. This provides for a dam and reservoir for flood control, regulation of streamflow for navigation, and develop- ment of hydroelectric power. The height above river bottom of the concrete gravity-type dam is about 190 feet, from elevation 690 feet to 880 feet above mean sea level. The spillway, with 568 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 crest at elevation 835, is controlled by 9 Tainter gates, 40 feet wide by 25 feet high, and 2 Tainter gates 20 feet wide by 25 feet high; it has a discharge capacity of 318,500 cubic feet per second with water surface at elevation 870.1. One 48-inch diameter sluicing conduit with free discharge valve, and 4 sluices 5 feet 8 inches wide by 10 feet high, are included in the dam. The reservoir, covering 19,200 acres at elevation 860, has a storage capacity of 671,000 acre-feet. The estimated cost (1957) is $31,321,000. The average annual maintenance cost during the past 5 years was $223,248. This project was authorized by the Flood Control Acts of August 18, 1941, and December 22, 1944 (Public Law 228, 77th Cong., 1st sess.), as outlined in House Document 674, 76th Congress, 3d session. Local cooperation. None required (sec. 2 of the Flood Control Act approved June 28, 1938, applies). Operations and results during fiscal year. New work, hired labor: Work in connection with acquisition of lands cost $2,642. Operation and maintenance: Operation and ordinary mainte- nance of dam, reservoir, powerhouse, service facilities and recrea- tional facilities, and supervision and administration incidental thereto cost $227,066. Replacement of appurtenances to dam and powerhouse cost $16,888. The net total cost for the fiscal year was $246,596, of which $2,642 was for new work, and $243,954 for operation and maintenance. Rains in the headwater area during the latter part of January 1957 caused a 12-foot rise in the pool elevation, impounding about 100,000 acre-feet, 75 percent of which was in flood-control storage. The natural stages at Rome, Ga., and Gadsden, Ala., were reduced about 2 feet. Corresponding reductions in flood losses were estimated at $82,700, all rural. Rains in April 1957 resulted in a rise of 11 feet in the reservoir pool elevation, impounding about 125,000 acre-feet, all of which was in flood-control storage. The natural stage at Rome, Ga., was reduced about 6.5 feet, and the stage at Gadsden, Ala., was Cost and financial statement Fiscal year ending June 30 Total to June 30, 1957 1953 1954 1955 1956 1957 New work: Appropriated ...... -$135,065 -$79, 978 $65, 000 $5, 659 $555 $31, 246, 191 Cost .---------------- 330,942 51,343 92,688 30,396 2,642 31,246,109 Maintenance: Appropriated ...... 235,000 241,960 185,500 213,500 246, 775 1,540,585 Cost_ --- 237,218 220,622 202,275 212,172 243,954 1,529,969 Other new work data: Unobligated balance, fiscal year ending June 30, 1957- -- $84 Unobligated balances available for succeeding fiscal year ending June 30, 1958 ____- 84 Estimated additional amount needed to be appropriated for completion of existing project__ _ 74, 800 FLOOD CONTROL-MOBILE, ALA., DISTRICT 569 reduced about 2.5 feet.

The Red River rises in the arid regions of eastern New Mexico, flows in a general easterly and southeasterly direction for 1,300 miles, and enters the Atchafalaya and Old Rivers and the Mississippi Ri.ver at Red River Landing, La., via Old River. (See U. S. Geological Survey State maps and Missis- sippi River Commission, Corps of Engineers, United States Army, alluvial valley quadrangle maps.) Previous projects. Authorized by River and Harbor Acts of May 23, 1828; June 10, 1872; June 18, 1878; March 3, 1879; August 2, 1882; July 5, 1884; August 11, 1888; and September 19, 1890. For further details, see page 1868 of Annual Report for 1915, and page 895 of Annual Report for 1938. Existing project. This provides for continuing improvement of Red River from Fulton, Ark., to the Atchafalaya River, La., 455.6 miles by systematic clearing of the banks, snagging, dredging shoals, building levees (either alone or in cooperation with riparian States), closing outlets, revetting caving banks, and preventing injurious cutoffs. The lower end of this project, RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 573 exclusive of Overton-Red River Waterway, is at Old River, 7.6 miles west of the Mississippi River. No proposed channel dimensions are given. Floods ordinarily cause fluctuations of stage between high and low water of from 30 to 45 feet. Unusual floods occasionally increase this range about 10 feet. The flood of March-April 1945 produced crest stages 1 to 3 feet higher than maximum previously recorded. As the work is continuing, no estimate for completion was made. The average annual maintenance cost during the past 5 years was $29,549. The existing project was authorized by the River and Harbor Act of July 13, 1892 (Annual Reports for 1890, p. 1829, and for 1891, p. 1957), and modified by the River and Harbor Act of July 24, 1946, to authorize construction of the Overton-Red River Waterway to Shreveport, La., and provide a channel 9 feet deep and 100 feet wide from the Mississippi River to the north bank of Black River (mile 35.5). (For latest published maps, see H. Doc. 378, 74th Cong., 2d sess.) Local cooperation. None required. Terminal facilities. None. Operations and results during fiscal year. Predredging and reconnaissance surveys and noncooperative stream gaging were carried on by hired labor at a cost of $3,663, and the U. S. dredge Nelson, under the jurisdiction of the United States Army Engineer District, Vicksburg, Miss., removed approximately 32,452 cubic yards of shoaled material from Kings Bayou Crossing during the period July 29 to August 5 and 13,174 cubic yards from Sugar House Chute and Three-Mile Bayou during the period November 18 to 22, 1956, at a cost of $27,268. The total cost for maintenance during the fiscal year was $30,931. Condition at end of fiscal year. Maintenance in recent years provides for navigation to Shreveport, La., at medium and high stages. The head of navigation is the Arkansas-Oklahoma State line, to which point boats may occasionally run during high water if snags, overhanging trees, or similar obstructions do not inter- fere. From January to July the prevailing stage is 6 feet and over, and controlling depths are about 4 feet to Fulton, 5 feet to Shreveport, and 6 feet to Alexandria. During the remainder of the year stages near zero may be expected, with controlling depths less than 1 foot from Fulton to Shreveport, 1 to 2 feet from Cost and financial statement Fiscal year ending June 30 Total to June 30, 1957 1 1953 1954 1955 1956 1957 New work: Appropriated -----------------------------------------------------------.. $1,963,806 Cost------.----------------------------------------------------------- 1,963,806 Maintenance: Appropriated -.---- $50,000 $14,000 $24,000 $29,000 $31,000 1,923,680 Cost----------------- 50,000 11,939 21,531 33,344 30,931 1,923,426 1Includes $1,553,878 for new work for previous projects. 574 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Shreveport to Alexandria, 4 feet from Alexandria to mouth of Black River, and 6.5 feet thence to mouth. The total costs under the existing project to the end of the fiscal year were $2,333,355, of which $409,929 was for new work and $1,923,426 for maintenance. 2. OVERTON-RED RIVER WATERWAY, LA. Location. The work covered by this improvement is located in the State of Louisiana between the junction of the Old and Mississippi Rivers and Shreveport, La., along the Old and Red Rivers, through landcuts and natural channels on the south bank of Red River. (See U. S. Geological Survey State maps and Mississippi River Commission, Corps of Engineers, United States Army, alluvial valley quadrangle maps.) Existing project. This improvement provides for a channel 206 miles long, 9 feet deep, and 100 feet wide, extending from the Mississippi River at mile 301.5 above the Head of Passes through Old River and Red River to mile 31, thence by a lateral canal extending through landcuts and existing waterways, across the Mississippi-Red River backwater area and along the south bank of Red River flood plain to Shreveport, La. The project includes the construction of nine locks, a pumping plant on Red River near Shreveport, bridges, drainage structures, and appurtenant work. Floods ordinarily cause fluctuations of stage between high and low water in Old River, Red River, and the backwater area of from 30 to 45 feet; the fluctuations of stages on the south bank tributary streams are somewhat less. The estimate of cost for new work is $96,800,000 (July 1957). This improvement was authorized by the River and Harbor Act approved July 24, 1946 (H. Doc. 320, 80th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Local interests are required to furnish free of cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas for new work and subsequent maintenance when and as required; make all necessary changes in existing highways, highway bridges, and approaches thereto, and all necessary changes in public utilities, except railroad facilities; maintain parts of all railroads, highways, bridges, and utilities affected by the improvement; establish, maintain, and operate adequate terminal and transfer facilities; and hold and save the United States free from damages incident to construction, maintenance, and operation of the improvement. A proposed constitutional amendment to establish a local state agency to furnish all requirements of local cooperation was presented to the voters of Louisiana in the November 1956 general election and was defeated. No advice has been issued by the State of Louisiana, Department of Public Works, as to what action is now proposed for furnishing the local cooperation required for the project. Terminal facilities. None. Operations and results during fiscal year. A comprehensive restudy of the benefits to be derived from the project was RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 575 conducted by members of the staff of the Board of Engineers for Rivers and Harbors, assisted by personnel of the division and district offices. Cost estimates were reviewed and refined in keeping with the present status of the planning. The results of these operations indicated that a favorable benefit-cost ratio for the project currently exists. The total cost for new work during the fiscal year was $56,047. Condition at end of fiscal year. Only preliminary planning work has been done to date. The total cost under the project to the end of the fiscal year was $420,402 for new work.

CHEFUNCTE RIVER AND BOGUE FALIA, LA. Location. The Chefuncte River rises in the upper portions of Tangipahoa and Washington Parishes, La., and flows southerly into Lake Pontchartrain, opposite New Orleans. (See U. S. Coast and Geodetic Survey Chart No. 1269, Corps of Engineers, Missis- sippi River Commission alluvial valley map, and Covington quadrangle.) Previous projects. Authorized by the River and Harbor Act of June 10, 1872. For further details of previous projects, see page 731, Annual Report for 1913, and page 783, Annual Report for 1938. Existing project. This provides for a channel 8 feet deep at mean Gulf level from that depth in Lake Pontchartrain via Chefuncte River and Bogue Falia to Washington Street, Coving- ton, La. The total length of improvement is 14 miles. Under ordinary conditions the mean range of tide at the mouth is about 10 inches, and near Covington about 3 inches, and the extreme range about 14 inches, and 5 inches, respectively. The variation of water surface in the upper Chefuncte River and Bogue Falia, due to floods, is about 8 feet; that in the lower Chefuncte River at Lake Pontchartrain, due to winds, is about 3 feet. The cost of new work for the existing project, completed in fiscal year 1929, was $19,342.24. The average annual maintenance cost during the past 5 years was $5,537. 576 REPORT OF THE CHIEF OF ENGINEERS, U. S.

On the lower Chefuncte, wharves used in connection with the boatyards have been constructed at Houltonville and Madisonville and these, in addition to minor wharves constructed by owners of pleasure boats, are adequate for navigation needs. On both waterways additional sites are available if needed. Operations and results during fiscal year. Reconnaissance sur- veys were carried on by hired labor during the fiscal year at a cost of $2,657 and the leased dredge Pontchartrainduring the period October 19 to 27, 1956, removed approximately 101,610 cubic yards of shoaled material in restoring the Chefuncte River bar channel to project dimensions for a distance of 0.68 mile, at a cost of $25,030. The total cost for maintenance during the fiscal year was $27,687. Condition at end of fiscal year. Because of the maintenance work performed under the previous project, the work required by the project adopted in 1930 was completed in 1929. The ob- structions in the Chefuncte River and Bogue Falia were originally removed in 1886, and the channel through the bar was originally dredged in 1903. The controlling depths, mean low Gulf, were: (October 1956), over the bar at the mouth of Chefuncte River, 8.3 feet; (July 1956), in the river to Madisonville Bridge, 11 feet; (September 1951), to mile 12, 11 feet; to mile 13, 6 feet; to mile 14, 2 feet. Overhanging trees are above mile 12. The total cost under existing project to the end of the fiscal year was $96,502, of which $19,342 was for new work and $77,160 was for maintenance.

GULF INTRACOASTAL WATERWAY BETWEEN APALACHEE BAY, FLA., AND THE MEXICAN BORDER (NEW ORLEANS DISTRICT) Location. The section of the Gulf Intracoastal Waterway with- in the New Orleans District extends from Lake Borgne Light No. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 577 41, near the mouth of the Rigolets, to the Sabine River, La., and Tex. The section from Lake Borgne Light No. 41 to the Mississippi River follows the Rigolets and Lake Pontchartrain to the lake end of the State-owned Inner Harbor Navigation Canal, thence by way of this canal to the Mississippi River, a distance of 40.5 miles. By Public Law No. 675, 77th Congress, approved July 23, 1942, the project was modified to provide for a landcut through the marsh from the Rigolets to a point on the Inner Harbor Navigation Canal about 2.25 miles from the Mississippi River, eliminating passage through Lake Pontchartrain and five drawbridges, a distance of 30.8 miles to the Mississippi River by this route. From the Inner Harbor Navigation Canal to the entrance to Harvey lock, the route follows the Mississippi River for a distance of 5.5 miles. The section from the Mississippi River to Atchafalaya River, La., leaves the Mississippi River through Harvey lock about 3.3 miles above Canal Street and follows Harvey Canal No. 1 and Bayou Barataria to Bayou Villars, a landcut south of Lake Salva- dor to Harvey Canal No. 2, Harvey Canal No. 2 to Larose, La., and a landcut to Houma, La., thence over a landcut south of Bayou Black and Bayou Cocodrie, thence through Bayou Cocodrie and a landcut to Bayou Black; thence through Bayou Black, Bayou Chene, and Bayou Boeuf to the Atchafalaya River, about 0.5 mile south of Morgan City, La., a total distance of 95.5 miles. The alternate connection with the Mississippi River in the vicinity of Algiers, La., about 10.3 miles below Harvey lock, con- sisting of a lock and landcut about 9 miles in length intersecting the Intracoastal Waterway at about mile 6, is complete. An alternate route from the Mississippi River at Plaquemine, La. (113 miles above New Orleans), follows Bayou Plaquemine passing Indian Village, La., and continuing on through lower Grand River to and through a lock at Bayou Sorrel in the East Atchafalaya Basin protection levee, thence through the levee borrow pit to Berwick Bay; and thence through Berwick Bay to Morgan City, La., a total distance of 56 miles. This alternate route is being enlarged from the vicinity of Morgan City to Indian Village, La., and is being extended from Indian Village, La., through Bayou Grosse Tete and a new landcut to and through a new terminal lock and entrance channel to the Mississippi River in the vicinity of Port Allen, La., a total distance of 65 miles. The section from the Atchafalaya River to Vermilion River, La., begins at the western end of the Mississippi-Atchafalaya section and follows the Atchafalaya River about 2.5 miles, portions of Little Wax Bayou, Possum Bayou, cutoffs, a landcut passing through North Bend Plantation to Bayou Bartholomew, Bayou Bartholomew to Little Bay, a landcut skirting the north edge of Cote Blanche Island and the west edge of Weeks Island to Ver- milion River, about 24 miles below Abbeville, La., a total distance of about 63.6 miles. Franklin Canal, St. Mary Parish, La., extends southwesterly from Franklin, La., on Bayou Teche, for 5.15 miles to Bayou Portage, a section of "The Inland Waterway from Franklin to the 578 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Mermentau River, La.," and through the bayou for 0.75 mile to the Gulf Intracoastal Waterway, 121 miles west of Harvey lock. The section from Vermilion River to Mermentau River, La., begins at the western end of the Atchafalaya-Vermilion section and follows Vermilion River 1.3 miles, a part of the Schooner Bayou cutoff canal, and a landcut running in a general north- westerly direction to Mermentau River at a point about 0.5 mile above its entrance into Grand Lake and about 16 miles below the town of Lake Arthur, La., a total distance of about 42.7 miles. Vermilion lock has been constructed about 1.75 miles west of Vermilion River to prevent the ingress of salt water from Vermilion Bay. The section from Mermentau River to Calcasieu River, La., begins at the western end of the Vermilion-Mermentau section and follows the Mermentau River upstream for about 1.5 miles, a landcut running in a west-southwesterly direction to Lake Misere, passing north of the lake and Bayou Misere, westerly to Sweet Lake, south and west of Sweet Lake, northwesterly to Bayou Tete Bois, through Bayou Tete Bois, Black Bayou and cutoffs to a point on Calcasieu River about 16.6 miles below the city of Lake Charles, La., a total distance of about 37.1 miles. Calcasieu lock has been constructed near the intersection of Calcasieu River and Intracoastal Waterway, mile 238 west of Harvey lock, Calcasieu Parish, approximately 16.6 miles below Lake Charles, La. The section from the Calcasieu River to Sabine River, La., and Tex., begins at the western end of the Mermentau-Calcasieu section, and follows the Calcasieu River upstream about 1.6 miles, a landcut running in a southwesterly direction 2.8 miles, thence west 22 miles to Sabine River at a point about 3 miles below Orange, Tex., a total distance of about 27.1 miles.

Previous projects. Previous projects for the different sections of this improvement were adopted by the following River and Harbor Acts: August 11, 1888; March 2, 1907; March 3, 1909; June 25, 1910; February 27, 1911; July 25, 1912; August 8,1917; July 18, 1918; March 2, 1919; and September 22, 1922. For further details, see pages 878-895 of Annual Report for 1924. Existing project. This provides for a waterway 384.1 miles long within the district which is 12 feet deep and 125 feet wide RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 579 at mean low Gulf, except in the section between Lake Borgne Light No. 41 and New Orleans (via landcut through the marsh and Industrial Canal), 33.1 miles long, where a width of 150 feet is provided; an alternate route 9 feet deep by 100 feet wide between Lake Borgne Light No. 41 and New Orleans (via Rigolets, Lake Pontchartrain, and Industrial Canal), 40.5 miles long; an alternate connection with the Mississippi River below Algiers, 12 feet deep and 125 feet wide about 9 miles long; a channel 12 feet' deep and 125 feet wide for the Plaquemine-Morgan City alternate route from the Mississippi-Atchafalaya section of the waterway, in the vicinity of Morgan City, through Lower Atchafalaya River (Berwick Bay) and the borrow pit of the East Atchafalaya protection levee to and through Bayou Sorrel lock which was constructed under the existing project "Flood control, Mississippi River and tributaries," thence through Lower Grand River to Indian Village, and thence by way of Bayou Grosse Tete and a new landcut to and through a new terminal lock and entrance channel to the Mississippi River in the vicinity of Port Allen, La., opposite the lower limit of the Port of Baton Rouge; a channel 9 feet deep and 100 feet wide from Indian Village on the Plaquemine-Morgan City alternate route through Bayou Plaque- mine and Plaquemine lock to the Mississippi River at Plaquemine, La.; improvement of Franklin Canal as a connecting channel from Gulf Intracoastal Waterway (mile 121) to Franklin, La., to afford a channel 8 feet deep and generally 60 feet wide with a width of 100 feet in its upper 300 feet; and a salt water guard lock (Calcasieu lock) in the waterway at mile 238 west of Harvey lock. The project also provides for the following: widening at bends; passing places; mooring basins; locks or guard locks; such railroad bridges over artificial cuts as are necessary; purchase of pipeline dredge; construction and operation of new drainage canals and pumping facilities to restore parish drainage systems where intercepted; construction of movable bridges at Missouri Pacific Railroad and State Highway Nos. 31 and 996 (in lieu of the State Highway Bridge No. 31, a tunnel was constructed, and the additional cost over estimated cost of bridge was borne by local interests); fixed-trestle bridges for crossing of proposed landside drainage canals; lift bridges at Louisiana Highway No. 168, Port Allen, La., at Texas and Pacific Railway, Port Allen, La., and at Texas and Pacific Railway, Morley, La.; and for annual payments to the Board of Commissioners of the Port of New Orleans for use of a portion of the Inner Harbor Navigation Canal. The length of the waterway within the district is 384.1 miles via the northerly or Port Allen route, and 299.4 miles via the southerly or Harvey Canal route. Under ordinary conditions the mean range of tide is about 10 inches and the extreme range is 14 inches. A severe storm may cause a high tide of from 6 to 9 feet. The estimate of cost for new work exclusive of amounts ex- pended on previous projects is $55,550,700 (July 1956) divided as follows: Algiers lock and canal $14,900,000; Plaquemine-Morgan City Route $24,800,000 (July 1957); and the remainder of the waterway $15,850,700 (July 1956). Construction of bulkheads and 580 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 jetties at Lake Borgne and Chef Menteur, La., is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this item was last revised in 1956 and estimated to be $440,000. The construction of a double-leaf bascule, four-lane highway bridge provided for under this project has become unnecessary due to the fact that the portion of the project over which the bridge was to be constructed has been incorporated in the project "Mississippi River-Gulf Outlet" which provides for a larger bridge. The average annual maintenance cost during the past 5 years was $1,626,894. Bayou Sorrel lock and Bayou Boeuf lock were constructed and are being maintained and operated with Flood Control, Mississippi River and Tributaries, funds. Therefore, construction, mainte- nance, and operation costs are not included in the approved estimates referred to hereinbefore. Inner Harbor Navigation Canal lock Miles below New Orleans, La.

Request has been submitted for Order of Immediate Possession. Terminal facilities. The terminals at New Orleans which are most generally used by Intracoastal Waterway traffic are those controlled by the State of Louisiana on the Inner Harbor Naviga- tion Canal. Since April 1, 1944, the portion from the Mississippi River to its intersection with the New Orleans-Rigolets section of the Gulf Intracoastal Waterway has been under lease to the United States and is now operated by the United States, toll free, 24 hours per day. Except for the terminal facilities at New Orleans, facilities are in general confined to privately owned piers, wharves, or oil docks. At Morgan City on the Atchafalaya River there are 2 large and 3 small wharves open to all without charge. The facilities are considered adequate for existing commerce.

The advertisement for bids is being held up pending a decision of the highway department's request for a review of vertical clearance of the bridge. Relocation of utilities continues to coincide with progress of the work. Work remaining to complete the project, other than that neces- sary to complete the Algiers alternate connection and the Plaque- mine-Morgan City alternate route, consists of the construction of bulkheads and jetties at Lake Borgne and Chef Menteur, La., if found necessary, in the Lake Borgne Light No. 41 to the Mississippi River section. In December 1956, project depths were obtained from Lake Borgne Light No. 41, La., to Sabine River, Tex., with the following exceptions: The controlling depth of the Plaquemine-Morgan City alternate route (June 1956) was 9 feet, and a deficient spot in the main channel (December 1956) was at mile 153.5 west of Harvey 588 REPORT OF THE CHIEF OF ENGINEERS, U.

The canal extends from Hanson lock to Bayou Teche through Hanson Canal and Bayou Portage to the Intracoastal Waterway, and along the Intracoastal Waterway to mile 161, west of Vermilion Bay. The total length of the waterway is 26.8 miles. (See U. S. Coast and Geodetic Survey Chart No. 1116; Corps of Engineers, Mississippi River Commission alluvial valley map, and Foster, Bayou Sale, Jeanerette, and Derouen quadrangles; U. S. Geological Survey maps, Abbeville (southeast), and Abbeville (southwest). Existing project. This project, as modified by the River and Harbor Act approved July 24, 1946 (S. Doc. 231, 79th Cong., 2d sess.), provides for a waterway from Bayou Teche at or near Franklin, La., to the western end of Vermilion Bay, having a depth of 5 feet below mean low Gulf and a bottom width of 40 feet, with appropriate side slopes; also the purchase of the Hanson Canal. This project, reported in the Annual Report for 1924 under the headings, Intracoastal Waterway, Franklin to Mermentau, La., and Intracoastal Waterway from Vermilion River to Schooner Bayou, La., has been superseded for most of its length by the project "Gulf Intracoastal Waterway (New Orleans District)." The River and Harbor Act approved July 24, 1946 (S. Doc. 231, RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 589 79th Cong., 2d sess.), authorized the incorporation of the exist- ing project "Inland Waterway from Franklin, La., to the Mermen- tau River," west of Vermilion Bay, in the modified Flood Control, General, project "Mermentau River, La." Under ordinary condi- tions the mean range of tides is about 10 inches and the extreme range about 14 inches. A severe storm may cause a high tide of from 6 to 9 feet. The estimate of cost for new work (revised in 1950) is $125,000. The average annual maintenance cost during the past 5 years was $1,991.

The project was considered complete prior to the modification by the River and Harbor Act approved July 24, 1946, which provided for channel enlargement and realinement from Vermilion Bay to White Lake and from White Lake to Grand Lake; for channel enlargement of North Prong of Schooner Bayou and for construction of a gated control structure in the new channel near Schooner Bayou lock, and the 590 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 incorporation of the existing project "Inland Waterway from Franklin to the Mermentau River, La.," west of Vermilion Bay, in the modified project "Mermentau River, La." The Hanson Canal and lock were acquired on October 16, 1923; the lockmaster's house was completed in 1924; and was moved to Berwick lock during the period August 27 to October 26, 1951. The United States property on which the lock is situated is a strip of land 300 feet wide between parallel lines running from Bayou Teche to Bayou Portage, containing 148 acres. Dredging from Vermilion Bay to the Mermentau River was completed in 1912. The controlling depths, mean low Gulf (October 1955) ; were: From Gulf Intracoastal Waterway through Cutoff Canal, 7 feet; to Schooner Bayou lock, 13 feet; to White Lake, 14 feet; over bar in White Lake, 4 feet; White Lake to Grand Lake (new cut) (Collicon Lake), 8 feet; and over bar in Grand Lake, 4 feet. The total cost to the end of the fiscal year was $797,702, of which $249,052 was for new work, $137,262 for maintenance, and $411,388 was for operating and care.

MISSISSIPPI RIVER, BATON ROUGE TO THE GULF OF MEXICO, LA. Location. The Mississippi River between Baton Rouge and the Gulf of Mexico flows in a general southeasterly direction through the southeastern portion of the State of Louisiana. At the Head of Passes, 233.1 miles below the Louisiana Highway Commission bridge at Baton Rouge, the river is broken up into 3 main passes: Southwest Pass, South Pass, and Pass a Loutre, 2 of which, South- west Pass and South Pass, are improved under the existing project. The distances from Head of Passes to the mouths of Southwest and South Passes are 20.1 miles and 13.5 miles, respec- tively. The mouth of Southwest Pass is 141 miles west of Mobile, Ala., and 349 miles east of Galveston, Tex. The mouth of South Pass is 18.5 miles northeast of the mouth of Southwest Pass. (See U. S. Coast and Geodetic Survey Charts Nos. 1269, 1271, and 1272; Corps of Engineers, Mississippi River Commission alluvial valley map and Zachary, Baton Rouge, White Castle, Donaldson- ville, Thibodaux, Mount Airy, Bonnet Carre, Hahnville, New Orleans, St. Bernard, Barataria, Pointe a la Hache, Black Bay, Empire, Forts, West Delta, East Delta, and Southwest Pass quadrangles and Folio of Flood Control and Navigation Maps, RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 591 Mississippi River, Cairo, Ill. to Gulf of Mexico, La., published by the president, Mississippi River Commission, Corps of En- gineers, U. S. Army.) Previous projects. Previous projects for the different sections of this improvement were adonted by the following River and Harbor Acts: July 4, 1836; March 3, 1837; August 30, 1852; July 8, 1856; March 3, 1875; June 19, 1878; March 3, 1879; June 6; 1900; June 13, 1902; May 28, 1908; March 3, 1909; January 21, 1927; June 26, 1934; and June 20, 1938. For further details, see page 1847, Annual Renort for 1915; page 724, Annual Report for 1937; pages 767 and 775, Annual Report for 1938; and page 602, Annual Report for 1956. Existing project. This provides for channel dimensions as follows: Between a line one-half mile below the Louisiana Highway Commission bridge at Baton Rouge and the upper port limits of New Orleans, a distance of 128.6 miles, 35 feet deep (mean low Gulf) by 500 feet. Within the limits of the port of New Orleans, where that author- ity has jurisdiction over both banks of the river, a distance of 17.2 miles, 35 feet deep (mean low Gulf) and a maximum width of 1.500 feet, measured from a line generally 100 feet from the face of the left-bank wharves, but not closer than 100 feet to wharves on the right bank. From the lower limits of the port of New Orleans to the Head of Passes, a distance of 86.7 miles, 40 feet deep (mean low Gulf) by 1,000 feet wide. Southwest Pass from Head of Passes to the outer ends of the jetties, a distance of 20.1 miles, 40 feet deep (mean low Gulf) by 800 feet wide. Southwest Pass bar, 40 feet deep (mean low Gulf) by 600 feet wide. South Pass from Head of Passes to the outer ends of the jetties, a distance of 13.5 miles, 30 feet deep (mean low Gulf) by 450 feet wide. South Pass bar, 30 feet deep (mean low Gulf) by 600 feet wide. The general plan of improvement of Southwest Pass provides for contracting the pass to uniform cross section with approxi- mately 1,420-foot surface width by means of jetties, spur dikes, and bulkheads: for channel improvement by dredging and retain- ing the dredged material between the dikes, bulkheads, and jetties; for dredging a channel through the outer bar inclining to the left of the jetty axis; for the construction of small revetted openings through the narrow portions of the banks of the pass for purpose of strengthening these banks; for closure of minor outlets not re- auired for maintenance of the banks; for the construction of sills to prevent the enlargement of the Jump and Cubits Gan; for dredg- ing to elevation minus 40 feet in the river at Head of Passes, as far as Cubits Gap, a distance of 3.5 miles; for repairs to sill across Pass a Loutre and bank revetment at Head of Passes: for construc- tion of dikes with a view to reducing the width of the river above Head of Passes; for the construction of a submerged deflecting 592 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 dike above the Head of Passes; and for other minor work. The east jetty is approximately 24,950 feet in length and the west jetty 19,699 feet. The jetties are composed of a substructure of brush mattresses, originally built to about the elevation of mean low water, surmounted with a superstructure of concrete and large riprap. Spur dikes are composed of cribwork of round pil- ing filled with willows and stone, or with a curtain of round piles along the upstream face. The general plan of improvement of South Pass provides for the construction and maintenance of jetties and spur dikes; mainte- nance of a sill across Pass a Loutre; for dredging a channel 40 feet deep and no specified width through the shoals of the river between Cubits Gap and Head of Passes, 3.5 miles, and for seaward exten- sion of east jetty at mouth of pass; removal of west dike and con- struction of spur dikes and bank revetment at Head of Passes; removal of false point at head of South Pass to bottom elevation of minus 45 feet and revetment of new bank line. The east jetty foundation is 12,070 feet long; the inner east jetty is 11,170 feet long; the west jetty is 7,820 feet long; and the inner west jetty is 4,710 feet long. The jetties are composed of a substructure of brush mattresses surmounted by a superstructure of stone and concrete. Spur dikes are composed of cribwork of round piling filled with willows and stone. The plane of reference is mean low Gulf level. Variation of water surface is 16 inches at the mouths and 10 inches at the heads of the passes, due to tides. The extreme range of tides at the mouths of the passes due to hurricanes is about 6 feet. At New Orleans the extreme range of water surface is about 20 feet due to floods. At Baton Rouge the extreme range is about 45 feet due to floods. The existing project was authorized by the River and Harbor Act of 1945 and modified by the River and Harbor Act of 1956, which provides for the construction of a seaway canal 36 feet deep and 500 feet wide from Micheaud to the 38-foot contour in the Gulf of Mexico and an inner tidewater harbor consisting of a 1.000- by 2,000-foot turning basin 36 feet deep and a connecting channel 36 feet deep and 500 feet wide to the Inner Harbor Navigation canal, and further provides, when economically justi- fled, for construction of a lock to the Mississippi River at Meraux, La. (The above-mentioned improvement authorized by the River and Harbor Act of 1956 will be reported on separately as the "Mississippi River-Gulf Outlet, La.") The estimate of cost for new work is $33,681,000 (July 1956). The average annual maintenance cost during the past 5 years was $1.642,676. Local cooperation. None required, except for modification of project in connection with Mississippi River to Gulf Outlet, which will be reported separately. Terminal facilities. Some 100 piers, wharves, or docks serve the Port of New Orleans. Practically all wharves on the east or left bank parallel the riverbank forming nearly a continuous covered quay about 10 miles long. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 593 A foreign trade zone is located in the Port of New Orleans. Public wharves controlled by the Board of Commissioners of the Port of New Orleans (the Dock Board) cover 62 percent of the im- proved waterfront. The board also controls the terminal facili- ties on the Inner Harbor navigation canal (the Industrial Canal) which connects the Mississippi River with Lake Pontchartrain and turning basin (1,000 by 1,000 feet). Since April 1, 1944, the por- tion of the Inner Harbor navigation canal from the Mississippi River to its intersection with the New Orleans-Rigolets section of the Gulf Intracoastal Waterway, exclusive of terminal facilities, but inclusive of the lock and the bridges at St. Claude Avenue and at Florida Avenue, has been under lease to the United States and is now operated by the United States on a toll-free basis, 24 hours per day. From the turning basin to the river the canal has a controlling depth of 30 feet. A quay wharf of reinforced con- crete, 265 feet wide by 2,400 feet long owned by the Dock Board is located on the west bank of the canal. All public port facilities are served by paved roadways (gener- ally city streets) and by the Public Belt Railroad, municipally owned and operated, which connects with all 12 trunk lines enter- ing New Orleans. The existing terminal facilities include a shipside grain elevator, general cargo and cotton wharves, fruit landings, bunkering facili- ties, terminal warehouses, railroad terminals, marine railways, and drydocks. They are considered adequate for present com- merce. (For further details see Port Series No. 20, "The Port of New Orleans, La." 1947.) Modern terminal facilities were installed by the city of Baton Rouge in 1926. A reinforced concrete dock for deep-sea vessels, 308 feet in length, has covered shed area of approximately 20,000 square feet and is equipped with a 12-ton locomotive crane. At- tached to the downstream end of the wharf is a floating wharf boat 231 by 401/2 feet, of 2,000-ton capacity. The facilities are served by a transfer boat and municipal terminal, having a capacity of 40 cars per day. Private terminals for handling oil and other products are lo- cated at points on both sides of the river between New Orleans and Baton Rouge. The facilities are considered adequate for the existing commerce. (For further details, see "Port Facilities" included in "Flood Con- trol and Navigation Maps of the Mississippi River, Cairo, Ill., to the Gulf of Mexico, Louisana," published by the president, Mississippi River Commission.) Operations and results during fiscal year. New work planning for improvement of Southwest Pass by hired labor consisted of installation of a system of hydrologic stations within the project area; collection of comprehensive prototype data for model verifi- cations; and sediment composition, salinity, tide and velocity, wind waves, discharge, bed contours, slush, and direction of flow studies. The costs were $255,703. 594 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Maintenance work performed on the project was as follows: a. Baton Rouge to New Orleans: A good channel was available in this section and no dredging was required on the river crossings. Reconnaissance surveys were made of Red Eye, Medora, Gra- nada, Philadelphia Point, Bayou Goula, Belmont, and Fairview Crossings by hired labor, as required. b. New Orleans Harbor: Maintenance dredging was accom- plished by leased dredges Pontchartrainand Tchefuncte under continuing contracts, removing 747,960 cubic yards of material from the channel to provide project dimensions within the harbor at New Orleans beyond the 100-foot line from the face of the wharves along the left bank, from the Napolean Avenue wharf intermittently downstream to and including the Bienville-Toulouse Street wharves.

On November 17, 1952, a supplemental agreement extended the contract for a period of 5 years. During the fiscal year under this reciprocal agreement 37,256 cubic yards were removed by leased dredges Pontchartrain and Tchefuncte from within the 100-foot line and 89,250 cubic yards were removed by the Board of Commissioners outside the 100-foot line. River traffic signal lights in the vicinity of Westwego, La., Gretna, La., and Governor Nicholls Street in New Orleans, to govern the movement of vessels during flood stages on the Mis- sissippi River in the vicinity of Algiers Point, Port of New Orleans, were in operation from February 13 to March 5, April 12 to May 17, and from May 27 through June 30, 1957. Necessary surveys to determine the condition of the channel in the harbor were made. Costs were as follows: Maintenance by contract: Dredging by leased plant $195, 810 Maintenance by hired labor: Surveys 4, 474 Operation of signal lights__ 21, 063 Total_--------------- - $221, 347 c.

S. dredge RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 595 Langfitt at the Head of Passes for a distance of approximately 2,400 feet along the entrance range into Southwest Pass. At Southwest Pass lower jetty channel and the bar channel, maintenance work consisted of dredging 6,766,667 cubic yards of material by hired labor and U. S. dredge Langfitt between mile 17.5 below Head of Passes and the sea buoy, a distance of approximately 13,975 feet. At miles 12.5 to 17.4 below Head of Passes in Southwest Pass, maintenance dredging was performed by hired labor and U. S. dredge Langfitt removing 1,023,295 cubic yards of material be- tween Ranges 184-C and 80-D for a distance of approximately 25,870 feet. In Southwest Pass between miles 11.9 and 13.3 on the west bank and between miles 9.3 and 10.2 on the east bank below Head of Passes hydraulic fill was placed until September 3, 1956, by leased dredge under continuing contract to strengthen the west and east banks of the pass where wave action from bay sides had caused excessive erosion. Construction of mooring clusters at Venice, La., for hopper dredge Langfitt initiated by contract in previous fiscal year, was completed on July 5, 1956, and strengthening of these mooring clusters by installing additional batter piles for lateral support, was accomplished by hired labor during the period July 16 to 20, 1956. Construction of 16 permeable pile dikes on the west bank of Southwest Pass between miles 10.0 to 13.5 below Head of Passes was accomplished by contract during the period December 5, 1956, to May 16, 1957, with approximately 1,151 tons of stone blanketing placed at landside end of each dike. Extension and restoration of east jetty and restoration of west jetty commenced by contract on February 11, 1957. Work on the east jetty is complete having placed approximately 23,108 tons of dike stone which extended the jetty upstream 700 linear feet, re- paired the jetty over a distance of 1,500 linear feet, and added additional stone over a distance of 8,900 linear feet. Work was in progress at the end of the fiscal year on the west jetty with approx- imately 558 cubic yards of concrete capping poured in forming 27 blocks on the jetty. Repair and maintenance of outlets and miscellaneous structures, inspections, routine channel surveys, miscellaneous hydraulic in- vestigations and examinations, and observations were made by hired labor forces. A portion of the former Burrwood reservation continued under lease to the United States Weather Bureau. A small guard force consisting of two men were kept at the reservation for protection of Government property. On May 28, 1957 bids were opened for sale of 36 buildings on the reservation consisting of 20 residences, 10 laundry sheds, the sheet metal shop, community center, post office, club store, dispen- sary, and cooks' quarters. Removal of the structures should be accomplished by September 30, 1957. 596 REPORT OF THE CHIEF OF ENGINEERS, U. S.

Minor deficiencies in project dimensions at the lower end of Du- maine Street and Governor Nicholls Street wharves in the New Orleans Harbor were not corrected because of the presence of re- vetment mattresses at these points. Existing depths opposite these locations are adequate for present and anticipated future commerce. The normal width of channel between 35-foot contours within the limits of the Port of New Orleans varies from 1,600 to 2,400 feet. Thalwag depths exceed 100 feet. Shoals along edges of the channel which develop at various points during high-river stages, make dredging necessary as the river stages fall, to maintain proj- ect depths to wharves along the east bank. Dredging by leased dredge was in progress at end of fiscal year. A natural channel of project dimensions or greater was available throughout the remainder of this portion of the project. hb. Southwest Pass: Deepening of the pass and bar channel from 35 to 40 feet, mean low Gulf, as approved by Act of March 2, 1945, is yet to be performed. Design and construction of model of Southwest Pass and the rational analysis of the prototype data collected to date have been comnleted. Maintenance dredging in Southwest Pass by hired labor is in progress. The east and west ietties are being repaired under continuing contract and restoration due to settlement will have to be resumed in fiscal year 1959. The west headland structure, Head of Passes, has been restored to effective grade and section. The east headland structure, 598 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 damaged by unknown vessels, requires extensive repairs which will be performed during fiscal year 1958. All existing permeable pile dikes for channel contraction are effective, but require some maintenance. Additional spur dikes were constructed during fiscal year 1957 on the west bank between miles 10.0 and 13.5 to build up the west bank of the pass and prevent further erosion by river action. For last complete report on the existing works of this pass, see pages 607 and 608 of the Annual Report for 1956. Channel conditions on June 30, 1957, were as follows: 35-foot channel Length Minimum of central channel Minimum Average depth (miles) width width (feet) (feet) (feet) Entrance channel into head of the pass .--- 1. 0 435 659 36 Through pass from head to sea end of jetties___ 19.1 1 330 787 34 Through bar channel at mouth of pass .-. 1. 3 700 810 38 1 This width at mile 19.9 in lower jetty channel. c. South Pass: A good channel was available throughout the length of the pass during the fiscal year with dredging required only on the bar. All outlets in the pass have been reinforced with stone to prevent erosion of banks on the South Pass side. The east jetty has been restored to effective grade and section and the west jetty, damaged on March 2, 1957, will be repaired by hired labor on a reimbursable basis. For last complete report on the existing works of this pass, see pages 608-609 of the Annual Report for 1956. Controlling channel conditions on June 30, 1957, were 31 feet over the bar channel at the Gulf entrance to the pass. Total costs under the existing project to the end of the fiscal year were $66,335,740, of which $25,552,604 was for new work and $40,783,136 for maintenance.

The work covered by this improvement is located in the State of Louisiana and extends from the existing Inner Harbor RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 599 Navigation Canal at a point 7,500 feet north of the existing lock and approximately 11,000 feet from the Mississippi River, to a turning basin south of Micheaud, La., and then as a land and water cut from the turning basin south of Micheaud, La., southeasterly to and along the south shore of Lake Borgne and through the marshes to and through Chandeleur Sound to the 38-foot contour in the Gulf of Mexico. Existing project. This improvement provides for a seaway canal, 36 feet deep and 500 feet wide, extending 76 miles as a land and water cut from Micheaud southeasterly to and along the south shore of Lake Borgne, and across Chandeleur Sound to Chandeleur Island and increasing gradually to a width of 600 feet and depth of 38 feet in the Gulf of Mexico, with protective jetties at the en- trance, a permanent retention dike through Chandeleur Sound, and a wing dike along the islands as required. It also provides for an inner tidewater harbor consisting of a 1,000- by 2,000-foot turning basin 36 feet deep at the landward end of the seaway canal, and a connecting channel 36 feet deep and 500 feet wide extending westerly along the Gulf Intracoastal Waterway from the turning basin to the Industrial Canal, including construction of a suitable highway bridge with approaches to carry Louisiana State High- way 47 (formerly 61) over the channel. The plan further pro- vides for the future construction of a channel and lock at Meraux to furnish an additional connection between the tidewater harbor and the Mississippi River. The estimate of cost for new work is $95,900,000 (July 1957). This improvement was authorized by the River and Harbor Act of March 29, 1956 (Public Law 455, 84th Cong., 2d sess.). The latest published map is in the project document (H. Doc. 245, 82d Cong., 1st. sess.). Local cooperation. Local interests are required to: (a) Fur- nish free of cost to the United States all lands, easements, rights- of-way, and spoil-disposal areas for the initial construction, and when and as required for subsequent maintenance; (b) accept ownership of the highway bridge and approaches upon completion of construction, together with maintenance, operation, and future replacement or alteration as may be required; (c) provide and maintain any other bridges required over the waterway, and ac- complish all necessary utility and other highway relocations and alterations and the maintenance thereof; (d) construct, maintain, and operate terminal facilities commensurate with requirements of the expanded port; and (e) hold and save the United States free from all claims for damages due to construction, maintenance, and operation of the project. The Board of Commissioners, Port of New Orleans, was desig- nated by the Governor of Louisiana as the local State agency to cooperate with the United States in the accomplishment of the project. The local agency furnished assurances of local coopera- tion required, which were forwarded on June 7, 1957, for approval of the Chief of Engineers. Right-of-way requirements for the portion of the project in Orleans Parish were furnished the local 600 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 agency on March 20, 1957. The Port Commission proposes to acquire fee title to all lands required in Orleans Parish and to con- vey the necessary easements to the United States over its fee lands. Plans for conveyance of rights-of-way in St. Bernard Parish are incomplete. The commission has requested waiver of the require- ment for Certificates of Guarantee of Title with authority to fur- nish its attorney's opinion as to validity of title. This request was forwarded to the Chief of Engineers on June 5, 1957. Operations and results during fiscal year. Planning, initiated during the fiscal year, consisted of surveys, reconnaissance soil borings in Chandeleur Sound to determine a tentative channel alignment, and assembling available information, such as historic United States Coast and Geodetic Survey field sheets, wind data, and geological and coastal processes of the area. A preliminary report was prepared also. A system of hydrologic stations was set up over the project area to collect data on current direction and velocity, wind direction and velocity, wave heights, salinity, and other information to aid in determining the most feasible route. The location of the first five miles of the channel at the New Orleans terminus was finalized. A detail design memorandum (No. 1A) covering this reach was prepared. Local interests were requested to acquire the rights-of-way and plans and specifications were completed for this reach. The total cost for new work during the fiscal year was $304,512. Condition at end of fiscal year. Only preliminary work has been done to date. The total cost under the project to the end of the fiscal year was $304,512 for new work.

BAYOU SEGNETTE WATERWAY, LA. Location. Bayou Segnette Waterway is a natural water traffic route, located in the lowlands of Jefferson Parish, La., just south of the Mississippi River, opposite New Orleans. The waterway heads at the mouth of an artificial canal known as Company or Westwego Canal, and ends where Bayou Villars is cut by the Intra- coastal Waterway. The channel prior to improvement included or traversed in turn, Bayou Segnette, Bayou Bordeaux, Lake Salvador, and Bayou Villars, and is 13.5 miles long. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 601 Existing project. The plan of improvement provides for a channel dredged to a depth of 9 feet below mean low Gulf level over a bottom width of 60 feet, commencing at the southern end of Com- pany Canal and following the existing channel of Bayou Segnette (including its cut-offs) southward to approximately mile 6.4; thence southerly via a new landcut lying to the east of Lake Salvador to Bayou Villars. The total length of improvement is 12.2 miles. The channel is to be maintained to a depth of 6 feet until such time as, in the discretion of the Chief of Engineers, maintenance to a greater depth not to exceed 9 feet is economically advisable. The estimate of cost (revised in 1957) is $374.000. This improvement was authorized by the River and Harbor Act of September 3, 1954 (H. Doc. 413, 83d Cong., 2d sess.). The latest published map is in the project document. Local cooperation. Local interests are required to: (a) furnish without cost to the United States all lands, easements, rights-of- way and suitable spoil-disposal areas necessary for the new work and for subsequent maintenance when and as required; (b) accom- plish and maintain without cost to the United States all necessary alterations in pipelines, and drainage and other facilities; (c) hold and save the United States free from damages due to construction and maintenance of the improvements; (d) maintain Company Canal free from vegetative growth obstructive to navigation and provide and maintain therein a minimum depth of 7 feet or a depth equivalent to that maintained in the Federal channel, which- ever is the lesser, for a width of at least 30 feet, with transit at published rates open to all on equal terms; (e) provide and main- tain a public wharf, not less than 20 feet wide and 200 feet long near the head of Bayou Segnette, accessible by highway and open to all on equal terms; and (f) cooperate with the Corps of Engi- neers in preventing the release of water hyacinths and other growths obstructive to navigation from local drainage ditches into the proposed improvement. Assurances of local cooperation were approved by the division engineer on August 15, 1956, and accepted by the district engineer. All rights-of-way required for construction have been acquired by the local agency and made available. No conveyance has been made to the United States and no title evidence has been furnished. The local agency has relocated all interfering utilities and pipe- lines. It is estimated that the local agency will commence trans- mitting deeds and title evidence for review in approximately 60 days. Terminal facilities. None. Operations and results during fiscal year. Drafting and engi- neering and design were carried on and plans and specifications, soil studies, and surveys were made by hired labor in connection with the improvement dredging in Bayou Segnette Waterway and the necessary rights-of-way were acquired for this dredging, all at a cost of $28,361 for new work. Improvement of Bayou Segnette Waterway, La., to elevation minus 6.0 feet mean low Gulf, over a bottom width of 60 feet, from 602 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 mile 0.0 to mile 12.2, was initiated by contract on January 10 and completed on June 21, 1957, with 644.1 stations excavated. During the period January 10 to April 11, 1957, approximately 306 stations were excavated in completing the channel between miles 6.4 to 12.2, 11.15 of these stations having been dredged by the sub- contractor's dredge Neches and the remaining stations by dragline. Approximately 338 stations were excavated by dragline in con- structing the new land cut from Bayou Segnette to Bayou Villars, La., between miles 0.0 to 6.4 during the period February 6 to June 21, 1957. Costs incurred during the fiscal year for this dredging amounted to $202,728 for new work. Total cost of new work for the fiscal year was $231,090. Condition at end of fiscal year. The project on which construc- tion was initiated January 10, 1957, is 62 percent complete. Work remaining to complete the project consists of dredging the waterway to a depth of not to exceed 9 feet, if and when found economically advisable. The total cost of the existing project to the end of the fiscal year was $231,090 for new work.

Under ordinary conditions the mean range of tide is about 10 inches at the mouth, 4 inches just below the lock, and zero above the lock, the extreme range of tide being about 12 inches, 6 inches, and zero, respectively. The variation of the water surface above Keystone lock due to freshets is from 2 to 7 feet, while just below the lock it has been as high as 12 or 15 feet and near the mouth about 4 or 5 feet. The estimate of cost for new work (revised in 1954) is $708,600, exclusive of amount expended on previous projects. Widening and deepening of the channel between mile 50.06 and Keystone lock and dam (mile 72) is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was 604 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 last revised in 1954, and was estimated to be $371,400. The average annual maintenance cost during the past 5 years was $57,275.

There are privately owned terminals for trans- ferring crude oil to barges near the towns of Charenton, Jeaner- ette. Olivier, and St. Martinville. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Hired labor carried on noncooperative stream gaging and reconnaissance surveys at a cost of $2,511, and initiated dredging of Bayou Teche between mile 5.5, Wax Lake outlet, to mile 19.5, Irish Bend, on February 18, 1957. At the end of the period approximately 196,231 cubic yards had been removed by Government and leased draglines in complet- ing intermittently approximately 2.43 miles of the channel and partially completing the improvement for the remainder of its length. This dredging is 80 percent complete with accrued costs of $70,334. Keystone lock was operated throughout the fiscal year, and the lock, dam, structure, and grounds were maintained, as necessary, with costs of $13,960. The raising of the pool level of Keystone lock by 1.5 feet above the dam was accomplished by contract during the period Septem- ber 19, 1956, to March 27, 1957, with costs for the fiscal year of $116,682. The total costs for the fiscal year were $203,487, of which $189,- 527 was for maintenance and $13,960 for operating and care. Condition at end of fiscal year. The existing project is approximately 67 percent complete. Keystone lock and dam was completed in 1913. The dredging and snagging done in 1916 completed that part of the existing project for the 6- by 50-foot channel from Arnaudville to Key- stone lock. The contract dredging done in 1918-20 completed that part of the previous project for a 6- by 50-foot channel from Keystone lock to mile 39.7 above the mouth. The 8- by 80-foot channel from New Iberia to the mouth is 98 percent complete. From the mouth to mile 5.8 a channel 8 by 80 feet, or greater, RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 605 already existed, and a new channel has been excavated, 8 by 80 feet, from this point to mile 50.06, about 3.65 miles below New Iberia, and 8 by 60 feet from this point to New Iberia. Keystone lock is in good condition and the pool level was raised by 1.5 feet above the dam by contract during the period September 19, 1956, to March 27, 1956. The controlling depths, mean low Gulf, were: (October 1954), from mile 0 to mile 6, 6 feet; to Charenton drainage canal (mile 29.5), 7 feet over pipeline crossing at miles 8 and 9, otherwise con- trolling depth, 9 feet; through "Y" Charenton drainage canal, 6 feet; to New Iberia (mile 54.5), 7 feet; (October 1953), to Key- stone lock (mile 72), 5 feet; controlling depths, mean low water, were: (May 1955), Keystone lock to Ruth Bridge (mile 87.0), 9 feet; Ruth Bridge to Ruth Canal (mile 87.5), 6.5 feet; Ruth Canal to Cecelia (mile 98.5), 4.5 feet; and Cecelia to Arnaudville Bridge (mile 106.5), 6 feet. The waterway is narrow with overhanging trees and drift rafts above Poche Bridge (mile 95.2). The total cost under the existing project to the end of the fiscal year was $1,654,288, of which $708,625 was for new work, $550,- 734 for maintenance, and $394,928 for operating and care. In addition, the sum of $91,389 was expended between July 1, 1913, and June 30, 1935, on the operation and care of the works of im- provement under the provisions of the permanent indefinite appropriation for such purposes.

BAYOU TECHE ANID VERMILLION RIVER, LA. Location. Bayou Teche has its source in Bayou Courtableau, in St. Landry Parish, and flows in a southeasterly direction a dis- tance of 125 miles to its confluence with the lower Atchafalaya River, about 101/2 miles above Morgan City, La. Vermilion River, also called Bayou Vermilion, is formed by the junction of Bayous Fusilier and Bourbeau, west of Arnaudville, La., and flows in a southwesterly direction to the western end of Vermilion Bay, a distance of 72 miles. Bayou Teche is connected with the Ver- milion River by Bayou Fusilier at Arnaudville; and by Ruth Canal, an artificial, privately owned, nonnavigable waterway, constructed for diversion of water from Bayou Teche to Ver- milion River for rice irrigation. (U. S. Coast and Geodetic Sur- vey Charts Nos. 1116 and 1277; Corps of Engineers, U. S. Army, 606 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Mississippi River Commission alluvial valley maps; and U. S. Geological Survey maps.) Existing project. This provides for the excavation of a navi- gable channel (51 miles long) 8 feet deep and 80 feet wide from the 8-foot depth contour in Vermilion Bay to the Gulf Intracoastal Waterway, thence 9 feet deep by 100 feet wide from the Gulf Intracoastal Waterway to Lafayette, La. (fixed bridge at Louisi- ana State Highway No. 1092), with additional enlargement below Abbeville necessary to provide adequate capacity for flood flows; improvement of Vermilion River from Lafayette, La., mile 52.0, to its junction with the lower end of Ruth Canal, mile 57.2, by both widening and deepening so as to provide a channel of 60-foot bottom width at minus 6.0 feet, mean Gulf level, in order to pro- vide adequate capacity for flood discharges from the upper Ver- milion River Basin, and also serve irrigation interests by conduct- ing the flow of Ruth Canal to the lower Vermilion River during the rice season. Clearing and enlargement of the channel from Ruth Canal to Bayou Fusilier by both widening and deepening so as to provide a cross-section approximately 50 percent larger than that of the existing channel. This improvement is required in the interest of flood control in the upper Vermilion Basin. Enlargement of the channel of Bayou Teche from it head in Bayou Courtableau to a point approximately 21 miles downstream thereof, by widening and deepening so as to provide a channel of 35-foot bottom width at minus 2 and minus 3, mean Gulf level. Increasing the height of Keystone Dam from its present crest elevation of 8.0 feet, above mean low Gulf, by 3 feet (later revised to 1.5 feet) by the installation of a fixed crest spillway. (See individual report of navigation project for Bayou Teche, La.) In connection with the improvements outlined above, the project provides for replacement of an existing pontoon bridge at Woodlawn on the navigable portion of Vermilion River with a vertical-lift structure. Relative minor work, consisting of lengthening and strengthening of approaches, is required on five existing movable bridges over Vermilion River below Lafayette, La., located at Louisiana State Highway No. 43 at Perry, La.; Southern Pacific Railroad at Abbeville, La.; Louisiana State Highway No. 25 at Abbeville, La.; Milton, La.; and United States Highway No. 90 (Pinhook Bridge) just below Lafayette, La. Similar work on existing fixed spans over nonnavigable streams is provided for on 11 bridges over Bayou Vermilion above Lafayette, La., and three over upper Bayou Teche. The estimate of cost for new work (approved in 1956) is $2,912,000. The average annual maintenance cost during the past 5 years was $36,476. The existing project was authorized by the Flood Control Act of August 18, 1941 (S. Doc. 93, 77th Cong., 1st sess., which also contains the latest published map). The project was reclassified as an "Operation and Maintenance, General" project under the RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 607 category, "Navigation (Locks, Dams, Reservoirs, and Canals)" by authority of the Office, Chief of Engineers, in 1st indorsement, April 23, 1956, on letter of the division engineer, Lower Mississippi Valley Division, March 6, 1956, subject: "Classification of the Mermentau River and Bayou Teche and Vermilion River, Opera- tion and Maintenance, General Projects." Local cooperation. Fully complied with for new work. Final acquisition of the rights-of-way for future maintenance by formal acts of conveyance is in process and local interests have completed acquisition of approximately 70 percent of rights-of- way required for maintenance. Operations and results during fiscal year. Hired labor con- tinued noncooperative stream gaging operations at a cost of $3,257 for maintenance. Condition at end of fiscal year. Construction under the project commenced on March 20, 1944, and was completed on March 27, 1957, when the crest of Keystone Dam was raised to provide an increase of 1.5 feet in the pool elevation, in order to increase the flow through Ruth Canal into Vermilion River. This work was accomplished under the navigation improvement "Bayou Teche, La." Channel improvements on Vermilion River consisted of con- structing an 8- by 80-foot channel from the 8-foot depth contour in Vermilion Bay to the Gulf Intracoastal Waterway; a 9- by 100- foot channel from Gulf Intracoastal Waterway to mile 52 (it was necessary to redredge Vermilion River channel between miles 36.9 and 46.0 during the fiscal year 1953, to reestablish project di- mensions, due to sedimentation caused by deposits from tributary streams excavated by local interests) ; and a 6- by 60-foot channel from mile 52 to mile 57.4. Channel enlargement was accom- plished between miles 3.5 and 17.5 and 57.4 and 76.21. Clearing and snagging was accomplished in Bayou Fusilier and Bayou Vermilion between miles 67.7 and 79, and an earth dike was con- structed in Bayou Fusilier. The channel of Bayou Teche was improved between miles 103.8 and 124.8. A new bridge was con- structed over Vermilion River at Woodlawn, the bridge at Milton was reconstructed; modification of bridges over Vermilion River above Lafayette, La., of fixed spans over upper Bayou Teche, of railroad bridge numbered 3.78, and of Louisiana State Highway bridges numbered 988 over Bayou Vermilion and 245 over Bayou Fusilier has been accomplished; the bridge at Pinhook was altered, and riprap was placed to insure bridge against possible damage by bank caving; and excavation and riprapping was performed in the vicinity of Southern Pacific Railroad bridge, Lafayette, La. Local interests have constructed improvements in Ruth Canal. The controlling depths, mean low Gulf, Vermilion River, were: (June 1956) Over bar, 6 feet; to Gulf Intracoastal Waterway, 10 feet; (October 1955) to Abbeville, 11 feet; to mile 49, 7 feet; and to highway bridge at Lafayette (mile 50.9), 5 feet, except a plug 600 feet long about one mile below the bridge, 3.5 feet. 608 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The total cost under the existing project to the end of the fiscal year was $3,180,227, of which $2,891,922 was for new work and $288,305, for maintenance.

MERMENTAU RIVER, LA. Location. The work covered by this project is located 35 to 70 miles southeast of Lake Charles, La., along the lower Mermentau River below Grand Lake, mile 25, to the Gulf of Mexico; the In- land Waterway from Vermilion Bay to White Lake, White Lake to Grand Lake, and from Schooner Bayou to the Intracoastal Waterway-Gulf section (Schooner Bayou cutoff); the North Prong of Schooner Bayou; and the waterway from White Lake to Pecan Island, La., an artificial canal, extending from the 5-foot- depth contour in White Lake, almost due south for a distance of approximately 1.8 miles to Pecan Island. (See U. S. Coast and Geodetic Survey Charts Nos. 1277 and 1278, and U. S. Geological Survey maps.) Previous project. Authorized by Flood Control Act of August 18, 1941. For further details, see page 1034 of Annual Report for 1946. Existing project. The plan of improvement covers flood con- trol, navigation, irrigation, and salinity control in the coastal marsh of the lower Mermentau River Basin and provides for channel enlargement of the lower Mermentau River below Grand Lake, mile 25, to a minimum section of 3,000 square feet below mean low Gulf level for discharge of floodflows; construction of a sector gated control structure at Catfish Point, mile 24 above mouth of Mermentau River, for discharge of flood flows and control of tidal flows and salt-water intrusion in the Mermentau River; channel enlargement and realinement of the Inland Waterway from Vermilion Bay to White Lake, 12.04 miles, and from White Lake to Grand Lake, 6.14 miles, to a minimum section of 3,000 square feet below mean low Gulf level or interflow between lakes and discharge of flood flows; construction of a sector gated con- trol structure in the enlarged channel immediately north of the abandoned Schooner Bayou lock reservation for discharge of floodflows and control of tidal flows and salt-water intrusion; channel enlargment of North Prong of Schooner Bayou and RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 609 Schooner Bayou cutoff, 6.69 miles, to 6 by 60 feet, mean low Gulf level, for navigation purposes; and maintenance of the existing 5- by 40-foot, mean low Gulf level, waterway from White Lake to Pecan Island, La., 1.8 miles long, for navigation. In addition, the project provides for the incorporation of that section of the project, "Inland Waterway from Franklin, La., to Mermentau River," west of Vermilion Bay, a waterway that included the Schooner Bayou lock. The project was reclassified as an "Operation and Maintenance, General" project under the category, "Navigation (Locks, Dams, Reservoirs, and Canals)" by authority of the Office, Chief of En- gineers, in 1st indorsement April 23, 1956, on letter of the division engineer, Lower Mississippi Valley Division, March 6, 1956, sub- ject: "Classification of the Mermentau River and Bayou Teche and Vermilion River, Operation and Maintenance, General Projects." Because of the failure of both east and west gates, Schooner Bayou lock has been closed by a dike across the east approach channel and traffic has been routed through the new control structure. Under ordinary conditions the mean range of tide on the Mermentau River near the mouth is 1.6 feet and near the head about 3 inches. The variation of the water surface near the mouth may be as much as 7 or 8 feet, due to hurricanes on the Gulf, and near the head from 8 to 12 feet, due to freshets. The estimate of cost for new work (approved in 1956) is $4,632,400. The average annual maintenance cost during the past 5 years was $73,184.

Local cooperation. Fully complied with. Operations and results during fiscal year. Reconnaissance sur- veys, engineering studies, and noncooperative stream gaging were carried on by hired labor at a cost of $13,560 for maintenance. 610 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Maintenance funds in the amount of $600 and $1,000 were transferred to the United States Weather Bureau and the United States Geological Survey, respectively, as the projects's pro rata share of costs for the operation of the cooperative hydroclimatic network and the cooperative stream-gaging program. Schooner Bayou and Catfish Point control structures were operated as required during the fiscal year to conserve fresh water by maintenance of normal lake stages and to prevent un- controlled tidal inflow during the rice irrigation season; to release promptly flood waters during abnormal stages; and to limit minimum stages in the interest of navigation. The costs were $16,896 and $31,960 for operation of Schooner Bayou and Catfish Point control structures. The total cost for the fiscal year was $64,016, of which $15,160 was for maintenance and $48,856 was for operating and care. Condition at end of fiscal year. The project, on which work commenced April 21, 1947, was completed July 10, 1952, except real estate activities. New work dredging on the existing project was accomplished during the period April 21, 1947, to June 21, 1952. Catfish Point control structure was constructed during the period November 6, 1948, to August 16, 1951. The reservation comprises 9.7 acres. Schooner Bayou lock and control structures: Schooner Bayou lock and dam were completed in 1913 and 1914, respectively, and the lockmaster's house in 1917. The lock was closed to naviga- tion May 7, 1951, and abandoned by authority of the Chief of Engineers on October 9, 1951. Permanent closure of the lock channel and tie-in dikes was completed on September 22, 1951. Construction of the control structure and dikes was accom- plished during the period August 8, 1949, to May 22, 1951. The reservation comprises 6.9 acres. Minor damage to operating machinery of these structures was sustained on June 27, 1957, as a result of high tides following hurricane "Audrey", making them inoperative for a short duration. The controlling depths, mean low Gulf, were: (October 1955) Mermentau River: Over bar, 6 feet; to Upper Mud Lake, 9 feet; through Upper Mud Lake, 8 feet; to Catfish Point, 9 feet; to Gulf Intracoastal Waterway through Grand Lake, 6 feet. Inland Waterway from Franklin to the Mermentau River: Gulf Intra- coastal Waterway through Cutoff Canal, 7 feet; to Schooner Bayou Control Structure, 13 feet; to White Lake, 14 feet; over bar in White Lake, 4 feet; to Grand Lake (new cut), 8 feet; over bar, 4 feet; North prong of Schooner Bayou (March 1952): Gulf Intracoastal Waterway to Schooner Bayou, 8 feet; at centerline, 6 by 60 feet; Waterway from White Lake to Pecan Island, La. (October 1955) : Over bar, 1 foot; to Pecan Island, 4 feet. The total cost under the existing project to the end of the fiscal year was $5,177,809, of which $4,631,910 was for new RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 611 work, $163,474 for maintenance, and $382,425 for operating and care, including $13,163, river and harbor funds. In addition, $2,000 was expended from contributed funds for maintenance.

CALCASIEU RIVER AND PASS, LA. Location. Calcasieu River has its source in southwestern Louisiana, and flows in a general southerly direction to the Gulf of Mexico. About 25 miles from the Gulf it debouches into Cal- casieu Lake, which lake is about 18 miles long. The connection between the lake and the Gulf, about 7 miles long, is known as Calcasieu Pass. (See U. S. Coast and Geodetic Survey Charts Nos. 591 and 592; U. S. Geological Survey maps, Edna, Thompson Bluff, Hecker, Moss Bluff, Lake Charles, West Lake, Moss Lake, Hackberry, Sweet Lake, Brown's Lake, Holly Beach, Grand Bayou, and Cameron quadrangles; and Corps of Engineers navigation maps of Intracoastal Waterway and Atchafalaya River system.) Previous projects. The original project for this improvement was adopted by the River and Harbor Act of June 10, 1872. Ap- propriations were made by the River and Harbor Acts of March 3, 1881, August 2, 1882, July 5, 1884, and August 11, 1888. The project was modified by the River and Harbor Acts of September 19, 1890, July 13, 1892, and September 22, 1922. For further details, see Annual Report for 1936, page 719, and Annual Report for 1938, page 819. Existing project. This provides for a channel 35 feet deep and 250 feet wide (49.5 miles long) from the wharves of the Lake Charles Harbor and Terminal District by way of Calcasieu River, including Clooney Island Loop, to the head of Choupique Cutoff; thence by a land-and-water cut along the west shore of Calcasieu Lake; thence to and through Calcasieu Pass by a designated route to the Gulf of Mexico, subject to such change in alinement as is ap- proved by the Chief of Engineers; the reconstruction and extension of the existing jetties initially to the seaward end of the east jetty, and further extension to the 15-foot depth contour if found ad- visable to reduce maintenance dredging costs; dredging a channel 35 to 37 feet deep and 250 feet wide between jetties, and an ap- proach channel 37 feet deep and 400 feet wide from the sea end of the jetties to a depth of 37 feet in the Gulf of Mexico; also for the 612 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 improvement of the river from Lake Charles to Phillips Bluff (52.6 miles) by removing logs, snags, overhanging trees, and by dredging. Total length of improvement is 102.1 miles. Under ordinary conditions, the mean range of tide is 10 inches at the mouth, diminishing to zero at Phillips Bluff, the extreme range being 14 inches and zero, respectively. The estimate of cost for new work, including $5,551,000 for the extension of the jetties to the 15-foot depth contour (revised in 1956), is $14,399,800. The average annual maintenance cost during the past 5 years was $212,949.

Local cooperation. Fully complied with. Under date of January 5, 1922, a permit was granted by the As- sistant Secretary of War to the police jury of Calcasieu Parish to enlarge this river where necessary between Lake Charles and the eastern end of the Calcasieu-Sabine section of the Intracoastal Waterway to a depth of 30 feet over a bottom width of 125 feet. Terminal facilities. Terminal facilities at the Port of Lake Charles are owned by the Lake Charles Harbor and Terminal Dis- trict and operated by a board of commissioners. In addition to the municipally owned terminals, there are several privately owned and operated wharf structures located on the existing ship chan- nel. (For further details, see Port Series No. 21, "The Port of Lake Charles, La.," revised 1947, and Folio of Navigation Maps, Intracoastal Waterway, New Orleans to Port Arthur, 1954, pub- lished by Mississippi River Commission, Corps of Engineers, United States Army.) Operations and results during fiscal year. Surveys, drafting, and engineering and design were accomplished by hired labor at a cost of $2,101 for new work. Real estate activities, hydraulic studies, salinity investigations, flow studies, noncooperative stream gaging, economic justification report, predredging and reconnaissance surveys, and danger zone and fairways studies were carried on by hired labor at a cost of $27,182. Funds in the amount of $500 were transferred to the United States Geological Survey as the project's pro rata share of costs for operation of the cooperative stream-gaging program. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 613 Retaining dikes were built during the period May 14 to 25 and topped on June 12 and 13, 1957, under a continuing contract for constructing a turning basin in vicinity of mile 29.5 and for ac- complishing maintenance dredging between miles 5.1 to 15.5 on Calcasieu River and Pass, La. Operations were suspended on June 13, 1957 to await the arrival of the contractors dredge. The costs for this work were $32,807. The total cost for the fiscal year was $62,590, of which $2,101 was for new work and $60,489 was for maintenance. Condition at end of fiscal year. The project as modified is 54 percent complete, including extension of the jetties seaward to the 15-foot depth contour; if and when found necessary. Dredging under the existing project, prior to the modifications adopted by the River and Harbor Acts of March 2, 1945, and July 24, 1946, was completed in 1941, and the 30- by 250-foot ship chan- nel was formally opened to deep-draft traffic on July 12, 1941. Work on the modified project of deepening the 250-foot channel to 35 feet from Lake Charles to the 37-foot depth contour in the Gulf of Mexico was initiated on September 7, 1948, and completed on April 25, 1953. This work was accomplished as follows: 35- by 250-foot channel from Lake Charles Harbor downstream: To Gulf Intracoastal Waterway, mile Commenced Completed 12.8, dredge Texas_ Sept. 7, 1948 Feb. 2, 1949 From Gulf Intracoastal Waterway, mile 12.8 to mile 24.1, dredge Duplex Sept. 5, 1949 Apr. 6, 1950 From mile 24.1 to mile 30.4, and dredging in the 6 by 20-foot connecting channel, dredge Texas and two draglines. _.

The Calcasieu Pass jetties, initiated under the previous project and completed in May 1942, extend to the 10-foot depth contour and are in good condition. The east jetty, approximately 8,620 feet long, has been built to approximately 6 feet above mean low Gulf, and extends seaward from the existing Gulf shoreline a dis- tance of 6,820 feet. The west jetty, 8,050 feet long, has been built to approximately 4 feet above mean low Gulf and extends seaward from the existing Gulf shoreline a distance of 6,795 feet. The jetty structure is considered complete unless at a later date 614 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 it is found necessary to extend the jetties seaward to the 15-foot depth contour, as provided for in the project. Work remaining to be done to complete the project consists of extending the jetties seaward to the 15-foot depth contour, if and when found necessary. The controlling depths, mean low Gulf, were: (February 1957), through jetty channel to mile 0, 33 feet, to upper and St. Johns Island (mile 5) deep and wide; (January 1957), through Cal- casieu Lake to mile 17.0, 27 feet; mile 17.0 to 20.4, 25 feet; to mile 23.9, 27 feet; to mile 27.4, 29 feet; to mile 31, 33 feet; to mile 34.4, 33 feet; to West Fork, 24 feet; (January 1954), to mile 50, 17 feet; to mile 51, 5 feet; to mile 53, 13 feet; to mile 57, 10 feet; to mile 63, 7 feet; to mile 65 (Hecker), 10 feet; to mile 70.4, 2 feet (nonnavigable above this point due to snags and trees). The total cost of the existing project to the end of the fiscal year was $10,011,560 of which $7,793,910 was for new work and $2,217,650 was for maintenance.

Lakes and streams tributary to the Gulf Coast. Existing project. This project provides for the removal of plants from the navigable waters. of the States of Florida, Ala- bama, Mississippi, Louisiana, and Texas, so far as they are or may become an obstruction to navigation, by any mechanical, chemical, The existing project was authorized by the following: Acts Work authorized Documents Mar. 3, 1899 Made appropriations for the States of Florida and H.

RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 615 or other means whatsoever; for the construction and operation of boats equipped with suitable machinery for such removal; and for the construction and operation of booms to prevent the drifting of plants from one stream to another. The average annual main- tenance cost during the past 5 years was $221,093. Local cooperation. None required. Terminal facilities. The terminal facilities of the various streams from which hyacinths were removed are described in the report for the improvement of these streams. Operationsand results during fiscal year. A well-balanced com- bination of mechanical and chemical methods of destruction was undertaken to take the maximum advantages of funds available. Economics in effect resulted in curtailed operations and limited the work to only those main waterways over which the major portion of navigation moves. Preventive maintenance work in secondary streams and feeder areas was sharply curtailed with a resultant increase in vegetation in these areas. Some momen- tary inconvenience was caused at times when this vegetation dis- gorged into the main streams after a heavy squall. Feeder areas previously freed of the hyacinth and placed on a patrol mainte- nance basis have now become heavily infested with alligator weed which has not proved susceptible to chemical treatment. A total of 40,611,750 square yards (8,267 acres) of vegetation was destroyed by chemicals and 7,607,750 square yards (1,572 acres) by machinery in Bayou Black, Lake Cataouatche and feeder streams, streams of the Lake des Allemands Basin, the Lake Dauterive area, the Intracoastal Waterway, Bayou Lafourche, streams of the Lake Maurepas Basin, the Bayou Penchant-Bayou Copassaw area, the Plaquemine Waterway, and in Bayous Teche, Misere, and Lacassine. Operations were conducted on a curtailed schedule with the work being confined to the main navigational channels on a recurring basis. Some handicap to navigation resulted. No permanent results can be expected on this basis as work must be accomplished in feeder areas and secondary streams if complete reinfestation of the main channels is to be avoided. Operations were conducted only in areas where severe hardship would have resulted if the work had not been undertaken. The total cost for the fiscal year was $241,738 for maintenance. Condition at end of fiscal year. From 1900 to 1902 a boat with suitable machinery for destroying the hyacinth by crushing was operated. From that time until 1937 hyacinths were destroyed through the use of a solution of arsenic and caustic soda which was sprayed on the vegetation, removal by hand crews and con- trolled in their movements by means of booms and barricades. The use of arsenic has been discontinued and hand removal has been supplanted by use of mechanical equipment in conjunction with the chemical spray (2,4-dichlorophenoxyacetic acid). Present methods of control are by means of mechanical rotary saw-type destroyers, chemical treatment, and the use of booms and barri- 616 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 cades. Excellent results are being obtained on water hyacinths by these methods. The total cost to the end of the fiscal year was $4,668,255 for maintenance.

McKinney Bayou rises in the northeastern part of Bowie County, Tex., and flows easterly an original distance of 76 miles, passing eight miles north of Texarkana, Tex., and entering Red River at mile 386. Flows from the upper 20 miles of this stream were diverted into Red River at mile 494.3 by levee and channel construction across McKinney Bayou below the mouth of Barkman Creek, a right-bank tributary, which rises in the hills to the south. Existing project. The plan of improvement provides for chan- nel clearing, realinement, and enlargement of McKinney Bayou 620 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 below mile 50; the enlargement of the existing hillside floodway levee between miles 12 and 14 and the extension thereof upstream to the mouth of Red Chute, mile 27, thence up Red Chute for 2 miles; the construction of a new levee and closure of high water outlets between miles 31 and 43, and the construction of ap- purtenant drainage works including a floodgate; all of which would reduce flood damage on approximately 26,000 acres of cropland. It also provides for channel clearing, realinement, and enlarge- ment, along Barkman Creek below the mouth of Jones Creek, mile 11, and along the canal for its diversion into Red River at mile 494, with construction of a supplementary new floodway levee and ap- purtenant drainage works which would reduce flood damage on approximately 4,000 acres of cropland. The estimate of cost for new work (approved in 1957) is $1,405,800 of which Federal costs are $1,290,00 and non-Federal costs are $115,800. The existing project was authorized by the Flood Control Act approved August 3, 1955 (H. Doc. 488, 83d Cong., 2d sess.). The latest published map is in the project document. Local cooperation. Local interests are to provide without cost to the United States all lands, easements, and rights-of-way, and make alterations and relocations of highways and related facilities, and utilities except railroads necessary for the construction; hold and save the United States free from damages due to the construc- tion; and maintain and operate all works after completion, and preserve channel capacities by preventing encroachment, in ac- cordance with regulations prescribed by the Secretary of the Army. Assurances of local cooperation for the McKinney Bayou area have been received from the Miller County, Ark., Improve- ment and Drainage District. The Bowie County, Tex., Levee Board No. 1 was requested to furnish assurances of local coopera- tion for the Barkman Creek area on December 6, 1956. That agency advised on March 26, 1957, that its financial status would not permit execution of the assurances required and did not state when its financial status would permit granting such assurances. Operations and results during fiscal year. Topographic and hydrographic surveys, soil investigations, hydraulic design studies, and preparation of the design memorandum for the Barkman Creek area were completed and the preparations of plans and specifications for construction are in progress. Surveys and hydraulic studies for the McKinney Bayou area were accomplished. Costs for the fiscal year were $18,672 for advance planning of new work by hired labor. Condition at the end of fiscal year. Preparation of plans and specifications for the Barkman Creek area and field surveys and office studies for the McKinney Bayou area are in progress.

COOPER RESERVOIR AND CHANNELS, TEX. Location. Cooper Dam and Reservoir is approximately 10 miles northwest of Sulphur Springs, Tex., and is at mile 29 on South Sulphur River, which rises in Fannin County, Tex., and flows generally east for approximately 80 miles to its confluence with the North Sulphur River to form Sulphur River. Existing project. The plan of improvement provides for the construction of an earth-fill dam with a height of about 42 feet above the valley floor, a length of 17,000 feet at its crest, and a gate-controlled spillway. The reservoir area would be 12,500 acres at the top of flood-control pool and 1,300 acres at top of con- servation pool. The plan of improvement also provides for chan- nel clearing, realinement, and enlargement; enlargement and ex- tension of existing levees; and the construction of appurtenant drainage works, along the main stem of Sulphur River above mile 126; channel clearing, realinement, and enlargement and levee enlargement and modification of appurtenant drainage works on Cuthand Creek below mile 24, on Sulphur River below mile 70, except in the proposed Cooper Reservoir, miles 29 to 42, and on Middle Sulphur River below mile 8; channel clearing and realine- ment on Brushy Creek below mile 5; and levee enlargement on North Sulphur River between miles 1 and 5. The estimate of cost for new work is $14,705,000, of which Federal costs are $13,350,000 and non-Federal costs are $1,355,000 (July 1957).

Eight counties in Texas and one county in Arkansas will be required to furnish assurances of local cooperation for the project. Details of the project and requirements of local cooperation were furnished the Red River Valley Association in August 1956. Seven counties in Texas have furnished resolutions indicating 622 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 their willingness to comply with requirements of local cooperation for features other than the Cooper Dam construction. Complete assurances have not yet been furnished by any local agency. Operations and results during fiscal year. Maps of the reser- voir area were partially completed under contract at a cost of $27,205. Additional surveys, soil borings, compilation of hydro- logic data and preliminary studies were carried on by hired labor forces at a cost of $82,888. An architect-engineer contract was awarded for engineering studies, design work, including prepara- tion of plans and specifications for the dam, reservoir, levees, and channel improvements. This work was brought to about six percent completion during the fiscal year at a cost of $1,545. The total cost for the fiscal year was $111,638 for advanced planning of new work.

OUACHITA AND BLACK RIVERS BELOW CAMDEN, ARK. Location. Ouachita River rises in Polk County, Ark., and flows about 600 miles in a general southeasterly and southerly direction through Arkansas and Louisiana. It is joined by the Tensas and Little Rivers at Jonesville, La., below which place it is called Black River, and enters Red River 35.5 miles above it mouth. (See Mississippi River Commission, Corps of Engineers, U. S. Army alluvial valley map and Moro Bay, Ingalls, Strong, Felsen- thal, Haile, Drew, Monroe, Columbia, Fort Necessity, Harrison- burg, Manifest, Tooleys, and Deer Park quadrangle maps), also folio of maps of the Ouachita-Black Rivers, Ark., and La., from Blakely Mountain Reservoir to Mississippi River including Old River and portion of Red River, scale 1: 62,500. Previous projects. The project was adopted by the River and Harbor Acts of March 3, 1871, June 10, 1872, August 14, 1876, and July 5, 1884. A separate project for work in the Ouachita River between Camden and Arkadelphia was adopted by the River and Harbor Act of August 11, 1888. For further details, see page 1869 of the Annual Report for 1915, and page 900 of the Annual Report for 1938. Existing project. This provides for a navigable depth of 61/9 feet at low water from the mouth of Black River, La., to Camden, 639 640 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Ark., a distance of 351 miles, by the construction of 6 locks and dams, with necessary dredging, and for removal of logs, wrecks and overhanging trees, etc., between mouth of Black River and Arkadelphia, Ark., 417 miles, and for a channel 7 feet deep and of suitable width from the improved channel of the Ouachita River above dam No. 6 to the vicinity of the railroad bridge over Lake St. Mary, thence a canal of the same depth and 70 feet in width along the south side of the railroad embankment to high ground with a suitable turning basin near Felsenthal, a distance of 3,600 feet. The project also provides for operation and care of all locks and dams included therein. The River and Harbor Act of May 17, 1950, authorized the modification of the existing project and the project for the Red River below Fulton, Ark., to provide a channel 9 feet deep and 100 feet wide from the authorized 9-foot navigation project at mile 31 on the Red River to the mouth of Black River at mile 35.5, thence from the mouth of Black River to Camden, Ark., mile 351 on the Ouachita River, to be obtained by lengthening and deepening the 6 existing locks, channel realinement cutoffs where necessary, re- habilitation of the dams, dredging and contraction works, in- cluding the deepening of the Felsenthal Canal below the previously authorized depth. Floods ordinarily caused fluctuations of stage from 25 to 45 feet between high and low water. Extreme floods occasionally increase this range about 10 feet. The latest approved (1957) estimate of cost for new work is $14,100,000.

Total estimated costs for all requirements of local cooperation under terms of the project authorization, in- cluding required non-Federal contributions, amount to $1,420,000, based on July, 1957 price levels. Terminal facilities. At Camden, Ark., there is a privately owned loading dock with a gasoline-operated crane. At Calion, Ark., there is a privately owned conveyor and dock for unloading logs. At Champagnolle Landing there is a privately owned dock for the loading of gasoline into barges, and a privately owned dock for unloading liquid sulfur from barges and loading petro- leum into barges. At Sterlington, La., there is a private loading dock for loading chemicals. At West Monroe, La., there is one privately owned warehouse. Terminal facilities are being expanded as required to meet the need of barge traffic. Operations and results during fiscal year. Advance engineer- ing and design for the modified project was continued. Mainte- nance dredging was done in the channel of the stream at 12 locations between Camden, Ark., and the mouth of Black River. A total of 154,094 cubic yards of material was moved by the U.S. cutterhead dredge Nelson. The six locks and dams were operated and maintained through- out the fiscal year by hired labor. Cost of advance engineering and design during the fiscal year was $66,623 for new work. The total cost of maintenance was $470,011 of which $226,289 was for maintenance dredging, and $243,722 was for operation and care of locks and dams. 'Condition at end of fiscal year. The project providing for a depth of 6.5 feet has been completed and is being maintained. New work under the modified project has not been started. The six locks and dams embraced in the existing project for slack-water improvement of the Ouachita River were completed in 1924 and provide navigation to Camden, Ark. (See table under existing project.) Construction of the canal to Felsenthal, authorized in 1937, has not been started. The head of navigation is Arkadelphia, Ark., to which point boats may occasionally run during high water if snags, overhang- ing trees, or similar obstructions do not interfere. From Janu- ary to June the gage at Monroe generally exceeds pool stage (13.3 feet), caused by the river above, and minimum depths exceeding 7 feet are usual between the mouth of Black River and Camden, Ark., a distance of 351 miles. At intervals during this period, the reading of the Camden gage exceeds 15 feet, and minimum depths of 7 feet may be expected between Camden and Arkadel- phia. During the remainder of the year the pools furnished by the six dams, with moderate dredging in Black and Ouachita Rivers, provide depths of 6.5 feet between the mouth of Black River and Camden, Ark., and depths of only a few inches may be expected between Camden and Arkdelphia, Ark. At the end of the fiscal year project depth of 6.5 feet below mean low water was available between Camden, Ark., and the mouth of Black River. RIVERS AND HARBORS-VICKSBURG, MISS., DISTRICT 643 The total costs to the end of the fiscal year under the existing project were $4,691,174 for new work, $5,115,492 for maintenance, and $3,389,244 for operation and care of locks and dams, totaling $13,195,910. In addition, the sum of $2,940,952 was expended between Janu- ary 25, 1913, and June 30, 1936, on the operation and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes.

Ouachita River rises in Polk County, Ark., and flows about 600 miles in a general southeasterly and southerly direction through Arkansas and Louisiana. It is joined by the Tensas and Little Rivers at Jonesville, La., below which place it is called Black River, and enters Red River 35.5 miles above its mouth." (See U. S. Geological Survey State maps; McAlester, Little Rock, El Dorado, Shreveport, and Natchez sheets of the U. S.

Army, Alluvial Valley quadrangle maps and folio of maps of the Ouachita-Black Rivers, Ark. and La., from Blakely Mountain Reservoir to Mississippi River including Old River and portion of Red River, scale 1:62,500.) The Ouachita River Basin embraces about 25,000 square miles. Headwater streams drain about 3,500 square miles of rugged terrain of the Ouachita Mountains (including some 1,500 square miles of the Ouachita National Forest). Downstream the basin comprises about 21,500 square miles of hilly uplands and broad plains. Below Riverton, La., approximately 1,490 square miles are in the Red River backwater area. Existing project. The River and Harbor Act of May 17, 1950 (S. Doc. No. 117, 81st Cong., 1st sess.), approved the general plan for flood control on Ouachita River and tributaries, Arkansas and Louisiana, which provides for the construction of one multi- ple-purpose and one flood-control reservoir; protection works for three localities and channel improvement at several points. This act further authorized the incorporation into the general plan of the several separate existing projects for flood control along the Ouachita River and tributaries in the basin above the lower end of the levees on the east bank of Ouachita River. The total estimated Federal cost of the project (1957) is $50,607,279 for new work, as itemized in the following tables: 3 Channels adequate for existing commerce. 4 Inactive project.

WOLF RIVER (MEMPHIS HARBOR), TENN. Location. Wolf River rises near the western edge of Tippah County, Miss., and flows generally northwesterly about 117 miles, through Shelby County, Tenn., emptying into the Mississippi River within the corporate limits of the city of Memphis, Tenn. (See Mississippi River Commission alluvial valley maps, scale 1:62,500, and scale 1:500,000.) Previous projects. The River and Harbor Act of August 18, 1894, authorized dredging at the mouth of Wolf River as an item in the improvement of Memphis Harbor, the work being carried out under the supervision of the Mississippi River Commission. Existing project. This provides for a channel 9 feet deep at low water from its mouth to Hindman Ferry Road (5.5 miles) with bottom widths of 250 feet from the mouth to Keel Avenue (mile 1.75) and 200 feet from Keel Avenue to North Second Street Road (mile 3.5), and thence 125 feet wide from North Second Street Road to Hindman Ferry Road. The portion of the project from the river mouth up to mile 3.0 is completed and maintained. The average annual mainte- nance cost during the past 5 years was $137,005. The remaining upstream portion of the project is to be restudied, and is excluded from the foregoing cost estimate. The construction cost of this upstream portion was last revised in 1954, and was estimated to be $900,000. The work of improvement up to mile 3.0 under the existing project was authorized September 6, 1933, by the Public Works Administration. The existing project was adopted by the River 653 654 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 and Harbor Act approved August 30, 1935 (Rivers and Harbors Committee Does. 26, 72d Cong., 1st sess. and 45, 74th Cong., 1st sess.) Sketch maps are printed in the project documents. Local cooperation. The work under the existing project is subject to the condition that local interests shall furnish, free of cost to the United States, all rights-of-way required for channel enlargement and straightening, and suitable areas with retaining levees where needed for disposal of dredged material during initial construction and future maintenance as and when needed, and shall furnish assurances satisfactory to the Secretary of Army saving the United States free from damages resulting from the work. The work is also subject to the provision that no works shall be undertaken on any section of the channel through or above any bridge until such bridge has been altered in a manner satisfactory to the Secretary of Army, without cost to the United States. The conditions as pertaining to the improvement up to mile 3.0 have been complied with. Terminal facilities. There are 24 terminals in the lower 3 miles of Wolf River. Five terminals are operated by common carriers, 3 by contract carriers, and 16 are operated privately. Operations and results during fiscal year. Maintenance dredg- ing during the fiscal year 1957 was conducted with one leased dredge, the Burlington, which moved a total of 696,574 cubic yards of material in maintaining a channel of project dimensions. The total costs for the year were $92,778. Condition at end of fiscal year. The portion of the existing project to mile 3.0 is complete and at the end of the fiscal year ample depths existed in the channel below a point 900 feet above Hall Street. Project depth at low water is maintained by dredging as required. Exclusive of maintenance dredging done during the fiscal year 1936 with Mississippi River funds which were included in the annual report of the Mississippi River Commission for that year under the caption "dredges and dredging," the total costs to June 30, 1957, were $2,334,604, of which $586,500 were from public work funds for new work, $1,730,604 were from regular funds for maintenance, and to cover the cost of retaining levees required Cost and financial statement Fiscal year ending June 30 Total to June 30, 1957 1953 1954 1955 1956 1957 J New work: Appropriated------------------------- ---------------------------------- $586,500 Cost- - -- ----------------- -------------------- 1 586,500 Maintenance: Appropriated .-------..... $88,730 $197,351 $253,000 $57,100 $86,000 21,731,028 Cost...----------------- 90,056 193,617 216,196 92,380 92,778 1,730,604 1 In addition, $17,500 for new work was expended from contributed funds. 2 Includes $35,000 deferred maintenance, channels and harbors funds.

Location. The work covered by this project lies within and ad- jacent to the city of Memphis in Shelby County, Tenn., on the left bank of Wolf River and the right bank of Nonconnah Creek from the confluence of these streams with the Mississippi River upstream for approximate distances of 10 and 4 miles, respective- ly. (See U. S. Geological Survey map of Tennessee, scale 1:500,000, and Mississippi River Commission alluvial valley maps, scale 1:62,500, 1:250,000, and 1:500,000.) Existing project. The plan of improvement provides for the construction of a system (eight sections) of levees, floodwalls, and bank protection, consisting of the following features: about 22,000 feet of earth levee and 2 concrete railroad floodgates along the right bank of Nonconnah Creek, extending from high ground near Tennessee Chute south of Riverside Park to high ground at Bodley Avenue east of Prospect Street; about 15,600 feet of con- crete floodwall, and 31,500 feet of earth levee along the left bank of Wolf River, extending from downtown Memphis to high ground near Douglas Park; construction of 6 new pumping sta- tions and 8 storage reservoirs with appurtenant works for the disposal of interior drainage; and the construction of a culvert under North Bellevue Boulevard near Cypress Creek for the enlargement of the Cypress Creek Reservoir. The project will provide protection, with 3 feet freeboard, for the city of Memphis and adjacent areas against a Mississippi River flood of 54.5 feet stage, or 4.1 feet higher than the maximum flood of record, which occurred in February 1937. The project was adopted by the Flood Control Act approved August 28, 1937, and so modified by the War Department Civil Appropriation Act approved June 28, 656 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 1939, that the cost of providing pumping stations and outlet works for interior drainage shall be borne by the United States, and further amended by the Flood Control Act approved July 24, 1946, to increase the total estimated cost of the project by $1,500,000.

The Mississippi River rises in Lake Itasca, Minn., and, from that lake flows in a southerly direction about 2,350 miles and empties into the Gulf of Mexico. The portion included in this report embraces the 195-mile section known as the middle Mississippi, between the tributary Ohio and Missouri Rivers, about 984 to 1,179 miles from the Gulf. See folder by U. S. Army Corps of Engineers of Navigation Charts Middle and Upper Mississippi River, Cairo to Minneapolis. Previous projects. The original project for the improvement of the Mississippi River between the Ohio and Missouri Rivers was recommended by a board of engineers in a report, dated April 13, 1872, and concurred in by the Chief of Engineers. For further details, see page 1879 of the Annual Report for 1915, and page 1014 of the Annual Report for 1938. Existing project. This provides for obtaining and maintaining a minimum channel depth of not less than 9 feet, a minimum width of not less than 300 feet at low water, with additional widths in bends from the mouth of the Ohio River (about 984 miles from the Gulf) to the northern boundary of the city of St. Louis, 191 miles; thence 200 feet wide, with additional width in bends to the mouth of the Missouri River, 4 miles; to be ob- tained: First, by regulating works, for closing sloughs and secondary channels, and narrowing the river; by building new banks where the natural width is excessive and protecting new and old banks from erosion where necessary to secure per- manency; second, by dredging or other temporary expedients to maintain channels of project dimensions; third, by construction of works authorized for the Chain of Rocks reach in the River and Harbor Act of March 2, 1945, which approved a comprehen- sive plan for development of the Mississippi River at Chain of Rocks so as to provide for construction of a lateral canal at an estimated first cost to the United States of approximately $10,290,000, with annual maintenance and operation cost of $70,000, subject to such modification as the Chief of Engineers may find necessary when the project is undertaken; and to authorize the relocation of the river channel and reclamation of the area in Sawyer for airport, park, recreational, and similar purposes at a cost to local interests of approximately $17,555,000: Provided, That any modification of the present river channel re- quired by the civic development be deferred until completion of the lateral canal in the interest of navigation and that the river diversion work connected with such civic development be under the supervision of the Chief of Engineers in order to insure that the interests of interstate and foreign commerce be properly pro- tected: And further provided, That local interests hold and save the United States free from any claims for damages that might be incurred due to the construction, maintenance, or operation of such civic development or any part thereof (H.

Terminal facilities. Most of the water terminal and transfer facilities of the district are described in volumes 1 and 4 of the 4-volume report of the Board of Engineers for Rivers and Har- bors, entitled "Survey of Terminals and Landings on the Inland Waterways of the United States". Operations and results during fiscal year. Construction works were carried on by contract and by hired labor with Government plant, weather conditions and river stages being favorable for construction during the year. Regulating works were main- tained, and project dimensions of channels were secured by dredging. New work: Costs of $29,682 were incurred on the improvement at Chain of Rocks as follows: $1,852 for distributive costs and by contract, $27,830 for payment of claim. By hired labor, en- gineering and design, $2,568; and other distributive costs, $17,425. 662 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 By contract $52,957 for revetment, and $175,046 for dikes. Total costs of new work were $277,678. Maintenance: Dikes (13,870 linear feet) and revetments (5,050 linear feet) were repaired by United States plant and hired labor at a cost of $520,189. The required 9-foot channel was maintained by two United States hydraulic dredges. Channel dredging was performed at 68 localities, removing 4,154,214 cubic yards of material from the main channel at a cost of $956,224. The channels dredged had a combined length of 26.42 miles, an average width of 285 feet, and an average gain in depth of 5.9 feet. Hydrographic surveys were made covering 143 miles of river, costing $35,316. Aids to navigation were installed at a cost of $46,912. Other costs were: flood forecasting and discharge observations, $8,616; cooperative hydro-climatic network (rain gages), $340; cooperative stream gaging (river gages), $15,941; non-cooperative stream gaging (river gages), $9,447; lock 27 lift gate chains, $3,037; payment of damage to Government structures by others, $5,047; distributive costs, $21,724; miscellaneous, $11,023; and damages to Government property and building and improvement credit, -$5,179. Work by contract consisted of $13,511 for stream gage repair. The cost of operating and care of lock No. 27 (and canal) was $172,256. Total costs $1,814,404. Deferred maintenance: For the rehabilitation of dikes, $50,846; and for dredging, $120,258. Work by contract consisted of $166,831 for rehabilitation of dikes. Total deferred maintenance costs were $377,935. Total cost of maintenance including operating and care was $2,152,339. Condition at end of fiscal year. Construction on the existing project was initiated in 1881, and the project has been in bene- ficial use practically from its inception. Work under the project, including the Chain of Rocks Canal is about 82 percent complete. The quantities required to complete the project are estimated at 97,995 linear feet of dikes, 104,275 linear feet of revetment, 280,000 cubic yards of rock removal, and minor items of work at Chain of Rocks. Dikes and revetments were in poor condition along some reaches of river due to critical damage inflicted by heavy ice flows during the winter of 1950-51 and by floods in spring and summer of 1951. The channel as a whole has been greatly improved by the work that has been completed to date. Dredging is required at low stages to remove temporary shoals and maintain the required channel depths. The project dimensions of channels have generally been main- tained throughout the navigation season. The navigation season formerly extended from the middle of February to the middle of December, the river being generally closed by ice the remainder of the year. However, in recent years increased demands of commerce and the use of steel hull boats have combined to extend the navigation season throughout the year except when blocked by heavy running ice or gorges. The river is generally RIVERS AND HARBORS-ST. LOUIS, MO., DISTRICT 663 above the 10-foot stage, St. Louis gage, for 6 months of the year, latter part of February to latter part of August, during which time project channel depths generally prevail without dredging. The mean stage of the river, St. Louis gage, was 1.90 feet for the fiscal year 1956 and 3.44 feet for the fiscal year 1957.

CARLYLE RESERVOIR, UPPER MISSISSIPPI RIVER BASIN, ILLINOIS Location. The Carlyle Reservoir will be located on the Kas- kaskia River, Ill., extending from about mile 107 to mile 155 above the mouth of that river, which enters the Mississippi River at mile 118 above the mouth of Ohio River. The dam will be located at mile 107, about one mile upstream from the town of Carlyle, and the proposed reservoir will extend northeastward through Clinton, Marion, Bond, and Fayette Counties, Ill. (See U. S. Geological Survey state and quadrangle maps.) Existing project. The plan of improvement provides for the construction of a compacted earthfill dam across the main valley floor, and a reinforced concrete spillway with tainter gates and sluices. The crest of the dam will be at elevation 474, approxi- mately 55 feet above the valley floor. The total length of the structure including the spillway section will be about 6,535 feet. The spillway structure will consist of an ogee overflow section surmounted by seven 40-foot by 30-foot tainter gates. The outlet works for controlling discharge under normal operating conditions FLOOD CONTROL---ST. LOUIS, MO., DISTRICT 685 will consist of four rectangular 8-foot by 10-foot sluices located in the nonoverflow section of the spillway. Because of the topog- raphy near the dam it will be necessary to construct 3 earthfill saddle dams, 1 north and 2 east of Carlyle, in order to contain the maximum pool level proposed for the reservoir. Total length of these embankments will be about 35,650 feet. The maximum res- ervoir area will be 57,500 acres. The total storage capacity is 983,000 acre-feet, of which 900,000 acre-feet will be for flood con- trol, 33,000 acre-feet for water supply, and 50,000 acre-feet for sediment retention. Total drainage area above the dam site is 2,680 square miles. The storage of floodwaters in the reservoir will provide substantial flood control benefits to about 75,000 acres of land along Kaskaskia River below the dam, in addition to pro- viding navigation and flood control benefits on the middle and lower Mississippi Rivers, and recreation, water supply, and fish and wildlife benefits on the Kaskaskia River. The Carlyle Reservoir was made eligible for selection as a unit of the general comprehensive plan for flood control and other pur- poses in the upper Mississippi River Basin under the Flood Control Act approved June 28, 1938. The latest estimate of the cost of the project (revised in 1957) is $36,100,000 of which $30,309,500 is for construction and $5,790,500 is for lands and damages. Local cooperation.

SABINE-NECHES WATERWAY, TEX. Location. This is a consolidation of the old improvements of "Harbor at Sabine Pass and Port Arthur Canal" and "Sabine- Neches Canal, including Sabine River to Orange and Neches River to Beaumont, Tex." Sabine Pass is on the Gulf of Mexico, approximately 58 miles east of Galveston and 280 miles west of Southwest Pass, Mississippi River. It connects Sabine Lake with the Gulf of Mexico. The Port Arthur Canal extends from near the upper end of Sabine Pass to the Port Arthur docks at the mouth of Taylors Bayou, a distance of 7 miles. Near its upper end, the Sabine-Neches Canal joins and extends to the mouth of 689 690 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the Neches and Sabine Rivers. The waterway next extends up the Neches River to Beaumont and up the Sabine River to Orange. (See U. S. Coast and Geodetic Survey Charts Nos. 517 and 533.) Previous projects. The original project for improvement of Sabine Pass was adopted by River and Harbor Act of March 3, 1875, and subsequent projects and modifications by River and Harbor Acts of August 2, 1882, June 3, 1896, June 13, 1902, and June 19, 1906. The Port Arthur Canal was conveyed to the United States free of cost in 1906, and the River and Harbor Act of July 25, 1912 incorporated it in the project. The Sabine and Neches Rivers were first improved under the River and Harbor Acts of June 18, 1878, and March 3, 1899, and the Sabine-Neches Canal was first improved under the River and Harbor Acts of March 3, 1905, and March 2, 1907. The project was enlarged by the River and Harbor Acts of February 27, 1911, July 25, 1912, March 2, 1919, and September 22, 1922. For further details, see page 1863 of Annual Report for 1915 for the Sabine and Neches Rivers, Sabine Pass, and Port Arthur Canal, and page 985 of the report for 1916 for Sabine-Neches Canal. (See also pp. 1100 and 1105 of Annual Report for 1921 and p. 874 of Annual Report for 1926.) Existing project.

The project also provides for two stone jetties at the Sabine Pass entrance from the Gulf of Mexico, the western jetty to be RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 691 21,860 feet long and the eastern jetty to be 25,270 feet long. The project further provides for the removal of the guard lock in the Sabine-Neches Canal, the construction of suitable permanent protective works along the Sabine Lake frontage owned by the city of Port Arthur to prevent dredged material from entering Sabine Lake and to prevent the erosion of the material deposited, the reconstruction of the Port Arthur Bridge, and the relocation of the Port Arthur field office. The mean tidal variation at the entrance is about 11/2 feet, at Port Arthur about 1 foot, and at Orange and Beaumont about five-tenths foot. Prolonged north winds during the winter sea- son have depressed the water surface as much as 3.4 feet below mean low tide while tropical disturbances have caused heights as much as 7 feet above mean low tide. The estimated cost for new work is as follows: Federal (Corps of Engineers) $24,938,000 (July 1957), exclusive of amount expended on previous projects, and non-Federal $3,046,000 (July 1957), including $385,500 contributed funds and value of useful work performed. The widening and deepening of the channel between Port Arthur west turning basin and Taylors Bayou turning basin, and the channel extension above the Cow Bayou turning basin near Orangefield portions of the project are con- sidered to be inactive and are excluded from the foregoing cost estimate. The cost of these portions was last revised in September 1954, and was estimated to be $73,000. The average annual maintenance cost during the past 5 years was $683,964, exclusive of $5,600,000 (July 1957) estimated cost of rehabilitating jetties.

The existing project provides for a channel 12 feet deep at mean low water over a bottom width of 125 feet, with such passing places, widening at bends, locks, or guard locks, and railway bridges over artificial cuts as are necessary from the Sabine River to Brownsville, Tex.; for the purchase or con- struction of a 20-inch pipeline dredge; for the maintenance of a suitable flood-discharge channel in the Colorado River from Matagorda, Tex., to the Gulf of Mexico; for a tributary channel 9 feet deep and 100 feet wide in the San Bernard River, extending from the main channel to the State highway bridge some 31 miles above the mouth of the stream; for a tributary channel in the Colorado River 9 feet deep and 100 feet wide, extending from the main channel upstream a distance of 17 miles, with a turning basin of the same depth, 400 feet wide and 500 feet long at the head of the improvement; for a tributary channel 9 feet deep RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 697 and 100 feet wide from Palacios, Tex., through Trespalacios and Matagorda Bays to the main channel; for a tributary channel 9 feet deep and 200 feet wide from the main channel to the harbor at Rockport, Tex., and improvement of that harbor to a depth of 9 feet; for rerouting the main channel along the north shore of Red Fish Bay between Aransas Bay and Corpus Christi Bay with no change in present authorized dimensions; for a tributary chan- nel 12 feet deep and 125 feet wide from the main channel near Port Aransas, Tex., to the town of Aransas Pass, Tex., ending in a basin of the same depth, 300 feet wide and 2,200 feet long; straighten and widen to 125 feet the connecting channel to Conn Brown Harbor and maintenance of Conn Brown Harbor, all to a depth of 12 feet; a tributary channel 9 feet deep and 100 feet wide extending from the main channel in San Antonio Bay to Victoria, Tex., for a side channel to Seadrift 9 feet deep and 100 feet wide connecting with the tributary channel to Victoria in San Antonio Bay; for a harbor of refuge at Seadrift 9 feet deep, 200 feet wide, and 1,000 feet long with an entrance channel 9 feet deep and 100 feet wide from the side channel to Seadrift; for a tributary chan- nel 12 feet deep and 125 feet wide in Red Fish Bay from the main channel to Port Mansfield with a turning basin 400 feet by 600 feet and 12 feet deep at Port Mansfield; for a tributary channel 12 feet deep and 125 feet wide from the main channel to the vicinity of Harlingen, Tex., via the Arroyo Colorado with a turning basin 12 feet deep, 400 feet wide, and 500 feet long at the upper end; for side channels 12 feet deep and 125 feet wide and 6 feet deep and 60 feet wide leading from Laguna Madre around the south part of Port Isabel, Tex., a total length of 11/2 miles; for an alternate channel 12 feet deep and 125 feet wide across South Galveston Bay between Bolivar Peninsula and the Galveston Causeway; and for operating and care of the waterway. From the Sabine River (3 miles below Orange, Tex.) to the Port Arthur Canal, from Port Bolivar to the west end of Galveston Channel, from Port Aransas to Corpus Christi and from Port Isabel to Brownsville, Tex., the waterway coincides with deep water channels improved and maintained under other projects. The mean tidal variation is 0.5 foot at Orange, 1 foot at Port Arthur, 1.3 feet in Galveston Bay, 1.5 feet at Freeport, 1 foot in Matagorda Bay, 1 foot in San Antonio Bay, 1 foot at Corpus Christi, 1.5 feet at Port Isabel, and 1.5 feet at Brownsville. The extreme ranges of tide under ordinary conditions are 1 foot at Orange, 1.5 feet at Port Arthur, 2 feet in Aransas Bay, 2.0 feet at Freeport, 1.5 feet in Matagorda Bay, 1.5 feet in San Antonio Bay, 1.5 feet at Corpus Christi, 2 feet at Port Isabel, and 1.5 feet at Brownsville. The height of tides is dependent largely on the wind. Strong north winds have depressed the water surface as much as 2 feet below mean low tide. The modified route of the main channel between Aransas Bay and Corpus Christi Bay is subject to the provision that no dredg- ing shall be done by the United States within 50 feet of any wharf or structure, the proposed drawbridge piers and fenders near Aransas Pass, Tex., being excepted from this provision. 698 REPORT OF THE CHIEF OF ENGINEERS, U.

RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 699 The tributary channel from Palacios, Tex., through Trespalacios and Matagorda Bays, the tributary channel to Aransas Pass, Tex., and the tributary channel to Harlingen, Tex., are subject to the provision that no dredging shall be done by the United States within 50 feet of any wharf or structure. The estimated cost for new work is as follows: Federal (Corps of Engineers) $36,807,000 (July 1957), exclusive of amount ex- pended on previous projects, and non-Federal $11,218,000 (July 1957), including $360,000 voluntarily expended. The upper 31/2 miles of the tributary channel in the San Bernard River, channel into Barroom Bay, and the upper 5 miles of the tributary channel to Harlingen via the Arroyo Colorado are portions of the project to be restudied. The estimated cost of the modifications including these portions is excluded from the foregoing cost estimate and was estimated in July 1954 to be $3,886,000 of which $1,851,000 has been completed. The average annual maintenance cost during the past 5 years was $1,188,236, including an average of $272,000 for operation and care of Mud Bayou Bridge, Brazos River Floodgates, and Colorado River locks. Operating and care of the waterway was included in the project July 1, 1935, under the provisions of the Permanent Appropria- tions Repeal Act approved June 26, 1934. Local cooperation.

Terminal facilities. There are terminal facilities at Orange, Port Arthur, Galveston, Freeport, Port Lavaca, Port Aransas, Corpus Christi, Port Isabel, and Brownsville where this waterway coincides with channels improved under other projects. (See Port Series No. 22 (Revised 1946), No. 23 (Revised 1948), and No. 25 (Revised 1948), Corps of Engineers, and reports on Freeport Harbor; Channel from Pass Cavallo to Port Lavaca, and Brazos Island Harbor, Tex.) Terminal facilities are under construction at Port Mansfield, and local interests are also con- structing additional harbor basins and an 8.8-mile channel exten- sion through Padre Island with parallel jetties in the Gulf of Mexico. These facilities should be completed early in 1958. There are privately owned piers and wharves at Port Bolivar, Palacios, Fulton, Rockport, Seadrift, North Seadrift, and Aransas Pass, and municipal wharves at Palacios and Aransas Pass. An assembling basin 300 feet wide by 5,500 feet long with mooring facilities, Government owned, is located at Port Bolivar, Tex., for interchange purposes of navigation between shallow- and deep- draft channels. The facilities are adequate for existing commerce. Operations and results during fiscal year.

GALVESTON HARBOR AND CHANNEL, TEX. Location. This is a consolidation of the authorized improve- ments at Galveston, Tex., which includes the projects formerly identified as Galveston Harbor, Tex.; Galveston Channel, Tex.; and the Galveston seawall extension. The entrance to Galveston Harbor is located on the Gulf of Mexico, on the northern portion of the coast of Texas, 328 miles west of Southwest Pass on the Mississippi River and 278 miles northeast from the mouth of the Rio Grande. Galveston Channel extends from a point in Galveston Harbor between Bolivar Peninsula and Fort Point across the former inner bar to and along the wharf front of Galveston, and has a length of about 5 miles and a width of 1,200 feet. (See U. S. Coast and Geodetic Survey Chart No. 520.) Previous projects. The original project for the improvement of Galveston Harbor, Tex., was authorized by the River and Harbor Acts of June 23, 1874, June 14, 1880, and August 5, 1886. For further details see page 1854, Annual Report for 1915, and page 851, Annual Report for 1938. Existing project. The existing project provides for a channel 800 feet wide and 38 feet deep, from deep water in the Gulf of Mexico to a point between the jetties 2 miles west of the seaward end of the north jetty, thence 800 feet wide and 36 feet deep to Bolivar Roads; a channel 36 feet deep at mean low tide and 1,200 feet wide from Bolivar Roads (outer end of the old inner bar near Fort Point) to 43d Street; for two rubblestone jetties extend- ing from Galveston Island (on the south) and Bolivar Peninsula (on the north) into the Gulf of Mexico (the south jetty being 35,900 feet long and the north jetty 25,907 feet long) ; the con- struction of 13 groins to protect the seawall along the Gulf shore from about 12th to 61st Street, Galveston, Tex.; for an extension of the seawall, which lies along the Gulf front of Galveston, from its angle at 6th Street and Broadway to the south jetty, with protection at its junction with the south jetty, and for an exten- sion of the existing seawall in a southwesterly direction from its present terminus near 61st Street for a distance of approximately 16,300 feet along the shore of the Gulf of Mexico. Under ordinary conditions, the mean tidal range in Galveston Harbor is 1.6 feet on the outer bar and 1.4 feet on the inner bar with extreme ranges of 2.3 and 2.1 feet, respectively. The mean tidal range in Galveston Channel is about 1.3 feet and the extreme range about 2 feet under ordinary conditions. The height of the tides in both Galveston Harbor and Channel is dependent largely 704 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimated cost for new work is as follows: Federal (Corps of Engineers) $16,918,000 (July 1957), and non-Federal $3,799,000 (July 1957), including $3,580,000 cash contributions. Extension of the 32-foot channel from 43d to 57th Street in the city of Galveston over a width of 1,200 feet to 51st Street and 1,000 feet thence to 57th Street is to be restudied and the cost of the modifications including these portions is excluded from the foregoing cost estimate.

The average annual maintenance cost during the past 5 years was $386,232, exclusive of $5,900,000 (July 1957) estimated cost of rehabilitating jetties. Local cooperation. Fully complied with except for the furnish- ing by local interests of assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from claims for damages due to the construction and maintenance of the Galveston Channel portion of the project as modified by the River and Harbor Act of June 30, 1948, and furnishing land easements required by the River and Harbor Act of May 17, 1950, in connection with the extension of the Galveston seawall subsequent to the initial extension by local interests. Terminal facilities. There are no terminals on Galveston Har- bor, but it is the entrance channel leading to the extensive terminal facilities located on Galveston Channel, Texas City Channel, and Houston Ship Channel. The terminal facilities on Galveston Channel are located almost entirely on the south side of the channel. The principal wharves are owned by the city of Galves- ton and extend from 10th Street to 41st Street. Piers and transit sheds have been constructed and timber bulkheads and aprons have been replaced with steel bulkheads, and concrete aprons and concrete slab decks at piers 10, 11, 12, 14, 34, 35, 36, 37, 38, and 40. (Code Nos. 958, 954, 952, 951, 917, 915, 912, 910, 909, 907, and 905, Port Series No. 23, revised 1948.) Reconstruction of Pier 29-33 (Code No. 918-924) is in progress. Wood bulkheads and open timber piles are being replaced with steel pile bulkheads, solid fill and concrete apron. Facilities are listed in the above Port Series and Port Series No. 6, Part 1, Corps of Engineers, and are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Con- dition surveys and miscellaneous inspections and reports were made at a cost of $4,306. Minor repairs to the seawall extension slope and pavement were made at a cost of $509. Preliminary surveys, plans, and specifications were made for dredging Galveston Channel at a cost of $52.

The existing project was about 52 percent complete, exclusive of inactive portions. The jetties 706 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,.1957 were completed in 1910. The 35-foot harbor channel was com- pleted in 1922. The first seawall extension, with fill and paving, was completed in 1926. The 36-foot outer bar harbor channel and the 34-foot Galveston Channel from Fort Point light to 43d Street was completed in the fiscal year 1938. The groins along the gulf side of Galveston seawall were completed in 1939. The inner and outer harbor bar channels were completed in the fiscal year 1950 to depths of 36 and 38 feet, respectively. The westward extension of the Galveston seawall, with fill and paving was approximately 26 percent complete at the end of fiscal year 1954. The work remaining, exclusive of portions to be restudied, consists of dredging Galveston Channel to a depth of 36 feet from Bolivar Roads to 43d Street; and completing the 16,300-foot extension of the existing Galveston seawall from its present terminus approxi- mately 5,400 feet southwest of 61st Street in a southwesterly direction along the shore of the Gulf of Mexico. The controlling depth over usable widths at mean low tide in the outer bar harbor channel, the inner bar harbor channel, and Galveston Channel were 37 feet, 37 feet, and 30 feet, respectively.

TEXAS CITY CHANNEL, TEX. Location. Texas City is on the mainland of Texas on the west side of Galveston Bay, about 10 miles northwest of the city of RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 707 Galveston. (See U. S. Coast and Geodetic Survey Charts Nos. 520 and 1282.) Previous projects. Adopted by River and Harbor Act ap- proved March 3, 1899, and enlarged by River and Harbor Act approved June 25, 1910 (H. Doc. 328, 61st Cong., 2d sess.). For further details see page 1856, Annual Report for 1915, and page 858, Annual Report for 1938. Existing project. This provides for a channel 36 feet deep at mean low tide and 400 feet wide on bottom from deepwater in Galveston Harbor to the harbor at Texas City, a distance of about 61/2 miles, with a pile dike on its north side 28,200 feet long covered with clay and other material dredged from the channel, with a harbor 1,000 feet wide on bottom and 36 feet deep at mean low tide extending approximately 4,250 feet to the southward of the south property line of the Monsanto Chemical Co., and for the construction of a rubblemound dike a short distance south of the existing pile dike and extending between stations - 1 + 600 (the shore) and 26 + 000, a distance of 27,600 feet. Under ordinary conditions the mean tidal range is about 1.3 feet and the extreme range is about 2 feet. The height of tide is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimated cost for new work is as follows: Federal (Corps of Engineers) $3,623,000 (July 1957), exclusive of amount ex- pended on previous projects, and non-Federal $28,700 (July 1957) all contributed funds. The average annual maintenance cost during the past 5 years was $52,801, exclusive of $830,000 (July 1957), estimated cost of rehabilitating rubble mound dike.

Local cooperation. Under the provisions of the River and Harbor Acts of August 26, 1937, and June 30, 1948, local interests are required to furnish free of cost to the United States necessary rights-of-way and suitable spoil-disposal areas for new work and for subsequent maintenance as required, and release the United 708 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 States from claims for damages attributable to the work of im- provement and furnish assurances satisfactory to the Secretary of the Army that they will construct a common-carrier oil terminal substantially as proposed. None of these conditions have been complied with. All prior requirements have been fully complied with. Terminal facilities. Modern terminal facilities, privately owned, are located on the mainland at the inner end of this channel and are considered adequate for existing commerce. (See Port Series, No. 23, revised 1948, Corps of Engineers.) A sea train terminal, privately owned, was completed in 1940. Operations and results during fiscal year. Maintenance: Con- dition surveys and miscellaneous inspections and reports were made at a cost of $1,073. Preliminary surveys, plans, and specifi- cations for dredging the channel were made at a cost of $872. The total cost for all work for fiscal year was $1,945. Condition at end of fiscal year. The existing project was about 63 percent complete. The work remaining consists of extending the turning basin 1,000 feet southward and enlarging the project, including the turning basin extension, to a depth of 36 feet over a bottom width of 400 feet in the channel and 1,000 feet in the turning basin. The channel and turning basin, except the authorized extension referred to above, were completed in 1937 to a depth of 34 feet over bottom widths of 300 feet and 800 feet, respectively. The pile dike was completed in 1915; the rubble- mound dike in 1934. The controlling depth over a usable width in the channel was 32 feet and in the completed portion of the turning basin was 30.5 feet at mean low tide. The total cost of the existing project to June 30, 1957, was as follows: New work Maintenance Total Regular funds----------------------------- $2, 151,680 $4, 486,556 $6, 638,236 Public works funds 136,296 -------------------- 136,296 Total United States funds ........... 2,287,976 4,486,556 6,774,532 Contributed funds_ ------------------------- 28,741 -------------------- 28,741 Total all funds ----------------------- 2,316,717 4,486,556 6,803,273 Cost and financial statement Fiscal year ending June 30 Total to June 30, 1957 12 1953 1954 1955 1956 1957 New work: Appropriated -- .... . ...-- ------ ------------------------------- $2,654,799 Cost--------------------- ----------------------- ------------- 2,654,799 Maintenance: Appropriated . -$12,130 $130,200 -$13, 000 $139,000 $1,073 4,682,057 Cost ----------------- 6,729 112,851 4,562 137,918 1,945 34,681,639 1 Includes $366,823 for new work and $195,083 for maintenance for previous projects. 2 In addition, $28,741 for new work was expended from contributed funds. 3 Includes costs for reconnaissance and condition surveys for fiscal years 1956 and 1957.

HOUSTON SHIP CHANNEL, TEX. Location. The channel connects Galveston Harbor, at a point opposite Port Bolivar, with the city of Houston, Tex., extending 50 miles in a northwesterly direction across Galveston Bay through the San Jacinto River and Buffalo Bayou to a turning basin at the head of Long Reach with light draft channel 7 miles long from the turning basin to Main Street, Houston. (See U. S. Coast and Geodetic Survey Charts Nos. 1282 and 532.) Previous projects. Authorized by River and Harbor Act of June 10, 1872, modified in 1877, and by River and Harbor Acts of March 3, 1879; March 3, 1899; February 20, 1900; March 3, 1905; and March 4, 1913. For further details see page 1856 of the Annual Report for 1915 and page 862 of the Annual Report for 1938. Existing project. This provides for a channel 36 feet deep at mean low tide from deepwater in Galveston Bay to and including the Houston turning basin, with a width of 400 feet from Bolivar Roads to 5,000 feet above Baytown, thence 350 feet to the mouth of Boggy Bayou, thence 300 feet to the Houston turning basin (about 1,000 feet wide); for turning points at the mouth of Hunting Bayou and at the lower end of Brady Island; for such off-channel silting basins on any part of the waterway as the Chief of Engineers may consider advisable; and for suitable widening of the bends at Lynchburg, Norsworthy, Manchester, and Harrisburg. The project also provides for suitable widening of the channel in front of the navigation district's wharf at Man- chester; for certain cutoffs and easing of sharp bends; and for a branch channel 10 feet deep at mean low tide and 60 feet wide in the old channel of Buffalo Bayou behind Brady Island. The mean tidal range under ordinary conditions is 0.6 foot to 1.3 feet in the lower part of Galveston Bay; 0.6 foot to 1.3 feet in the upper bay; and 0.5 foot to 1 foot in the San Jacinto River and Buffalo Bayou. The extreme ranges under ordinary conditions are about 2 feet, 1.2 feet, and 1 foot, respectively. Freshets sometimes cause rises of over 12 feet in Buffalo Bayou. The height of the tides, however, is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimated cost for new work is as follows: Federal (Corps of Engineers) $18,433,000 (July 1957), exclusive of amount expended on previous projects, and non-Federal $7,716,000 (July 1957), including $1,365,000 contributed. The construction of a dike 26,000 feet long in upper Galveston Bay and the light draft extension of the channel, 10 feet deep and 60 feet wide, in Buffalo Bayou from the turning basin to the mouth of White Oak Bayou, portions of the project are considered to be inactive and are excluded from the foregoing estimate. The cost of these portions was last revised in July 1954 and was estimated to be $298,000. The average annual maintenance cost during the past 5 years was $603,390. 710 REPORT OF THE CHIEF OF ENGINEERS, U. S.

ANAHUAC CHANNEL, TEX. Location. The town of Anahuac is on the northeast side of upper Galveston or Trinity Bay, opposite the mouth of the Trinity River, 38 miles north of Galveston and 25 miles northeast of Seabrook. (See U. S. Coast and Geodetic Survey Chart No. 1282.) Existing project. There is no definite project for this channel. The River and Harbor Act approved March 3, 1905, contained an item for "Improving West Galveston Bay Channel, Double Bayou, and mouths of adjacent streams, including Trinity River, Anahuac Channel, and Cedar Bayou," but at the time of the appropriation no recommendation of definite channel dimensions had been made to Congress. A channel 6 feet deep at mean low tide and 80 feet wide was dredged in 1905 from Galveston Bay to the wharves at Anahuac, a distance of 16,000 feet. Under ordinary conditions the mean tidal range is about 0.75 foot and the extreme range is about 1.2 feet. The height of tide is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 11/2 feet below mean low tide. RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 713 The average annual maintenance cost during the past 5 years was $24,386. The latest published map is contained in House Document 440, 56th Congress, 1st session. Local cooperation. None required. Terminal facilities. The terminal facilities are at Anahuac and consist of several small privately owned wharves and slips for local use. They are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Con- dition surveys and miscellaneous inspections and reports were made at a cost of $416. Preliminary surveys, plans, and specifica- tions were made for dredging the channel from Beacon 17 to 1.1 miles bayward from Beacon 9 at a cost of $1,337, and work under the contract was performed during the period June 14 to 30, 1957, removing 71,200 cubic yards of material over a channel length of 4,690 linear feet at a cost of $19,876. The total cost of all work for the fiscal year was $21,629. Condition at end of fiscal year. The existing project was com- pleted in 1911. The controlling depth over a usable width was 6 feet at mean low tide. The total cost of the existing project to June 30, 1957, was $655,254, of which $5,975 was for new work and $649,279 was for maintenance.

TRINITY RIVER AND TRIBUTARIES, TEX. Location. This river rises in north central Texas and flows southeasterly about 760 miles, discharging into Galveston Bay, 37 miles northeasterly from Galveston (U. S. Geological Survey base map, Texas, scale 1:500,000). Previous projects. The project outlined in House Document 409, 56th Congress, 1st session, was adopted in part by the River and Harbor Acts of June 13, 1902, March 3, 1905, March 2, 1907, June 25, 1910, July 25, 1912, March 4, 1913, and July 27, 1916, each of which acts authorized the construction of certain named locks and dams. The portion of the project relating to locks and dams construction was abandoned by the River and Harbor Act of September 22, 1922. For further details, see page 1113 of Annual Report for 1921, and page 986 of Annual Report for 1932. Existing project. With abandonment of the lock and dam construction, the improvement of the Trinity River by a channel 6 feet deep and of navigable width from the mouth to Liberty (river mile 41.4) was left as the existing project, being continued as provided for in the River and Harbor Act of July 25, 1912. The 714 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,_1957 existing project was modified by the River and Harbor Act of March 2, 1945, which approved a comprehensive plan of develop- ment of the Trinity River and tributaries, Texas, in accordance with the recommendations set forth in House Document 403, 77th Congress, 1st session, subject to such future modifications as in the discretion of the Chief of Engineers and the Secretary of the Army may be advisable. That comprehensive plan of development provided for a navigable channel from a point in Galveston Bay at the Houston Ship Channel to a terminus at Fort Worth, Tex. Such navigable channel was to be not less than 9 feet in depth, and to have a minimum bottom width of 200 feet in Galveston Bay and 150 feet in the river section on tangents, with shunting places and suitable widening on curves, and with a turning basin at Liberty. The navigation locks would have clear inside dimensions of 75 feet by 400 feet. The 1945 act, however, authorized for construction at this time only that portion of the channel as far upstream as Liberty, Tex. The River and Harbor Act of July 24, 1946, further modified the comprehensive plan for the Trinity River Basin development so as to locate the section of the navigation channel below Anahuac nearer the eastern shore of Trinity Bay, in accordance with the recommendations of the Chief of Engineers in House Document 634, 79th Congress, 2d session. This modification provides for a navigation channel 9 feet deep and 150 feet wide from the Houston Ship Channel near Red Fish Reef along the easterly shore of Galveston Bay with a protective embankment to the mouth of the Trinity River near Anahuac. The estimated Federal cost of this portion of the comprehensive plan below Liberty is $7,750,000 (1949), exclusive of amounts expended on previous projects. This portion of the project is being restudied. The average annual maintenance cost during the past 5 years was $12,526. The latest published maps are contained in House Document 634, 79th Congress. The estimated first cost to the United States of the approved comprehensive plan for canalization to Fort Worth is $96 million (1939 prices), with $1,760,000 annually for maintenance and operation. Under ordinary conditions the mean tidal range in the bay is from about 0.6 foot to about 1.2 feet. The height of tide is depen- dent largerly on the wind, and during strong northerly winds in the winter season the water surface may be depressed 1.5 feet below mean low tide. Local cooperation. The work recommended in House Docu- ment 403, 77th Congress, is authorized subject to the conditions that local interests furnish necessary rights-of-way, suitable areas for disposal of dredging material, and make necessary changes in utilities crossing the natural river channel below Liberty; and give assurances satisfactory to the Secretary of the Army that they will provide adequate terminal and transfer facilities on the waterway, and hold and save the United States free from claims for damages that may result from construction and operation of the improvements. RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 715 Local interests have not complied with conditions of local cooperation for the portion of the channel from Anahuac to Liberty, but have fully complied with the conditions contained in House Document 634, 79th Congress, 2d session, for the completed portion of the channel below Anahuac. Terminal facilities. There are 5 wharves on this river between the mouth and a point 38 miles upstream at Liberty, Tex. Four range from 10 to 20 feet in length; the fifth, at Liberty, is 150 feet in length. All are privately owned, and usage is free at all except one. One has a hand derrick; the other 4 have no freight-handling facilities. They have no physical connection with any railroad. They are adequate for the existing commerce, and there is ample room for future enlargement. The Texas Gulf Sulphur Co. has constructed a channel 12.5 feet deep, 100 feet wide, and 4,500 feet long from mile 11.1 on the Trinity River to a slip 12.5 feet deep, 380 feet wide, and 1,320 feet long, with terminal and transfer facilities for the unloading of sulphur from the Moss Bluff mines. Operations and results during fiscal year. Maintenance: Con- dition surveys and miscellaneous inspections and reports were made at a cost of $157. The total cost for all work for fiscal year was $157. Condition at end of fiscal year. The navigation channel below Liberty, Tex., is 13 percent complete. The original project was completed in 1925. The channel from its junction with the Houston Ship Channel to a point 1 mile below Anahuac, Tex., has been dredged to a depth of 9 feet below mean low tide over a bottom width of 150 feet. The controlling depth over a usable width between the Houston Ship Channel and a point 1 mile below Anahuac, Tex., was 2.5 feet, between the mouth of the Trinity River and mile 28.5 was 6 feet, and 3 feet thence to Liberty at mean low tide. Authorized construction remaining under the comprehensive plan consists of completing that portion of the navigation channel from 1 mile below Anahuac to Liberty, Tex. The total cost of the existing project to June 30, 1957, was $1,274,391, of which $1,042,660 was for new work and $231,731 was for maintenance.

CLEAR CREEK AND CLEAR LAKE, TEX. Location. Clear Creek has its source about 13 miles south of Houston, Tex., and flows southeast for a distance of about 25 miles, emptying into the west side of upper Galveston Bay at a point 24 miles northwest of Galveston, Tex. (See U. S. Coast and Geodetic Survey Chart No. 1282.) Existing project. This provides for a channel 7 feet deep at mean low tide and 75 feet wide from deep water in Galveston Bay to a new entrance to Clear Creek, and a channel 7 feet deep and 60 feet wide in Clear Creek and Clear Lake to the county highway bridge at League City. Under ordinary conditions the mean tidal range is about 0.8 foot and the extreme range is 1.4 feet. The height of tides is dependent largely on the wind and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The average annual maintenance cost during the past 5 years was $9,151.

This harbor is formed by the improvement of the Brazos River, Tex., from the mouth to Freeport about 6 miles above. (See U. S. Coast and Geodetic Survey Chart No. 525.) The mouth of the Brazos River is about 47 miles southwest of Galveston Harbor entrance and about 137 miles northeast of Aransas Pass (Port Aransas). Previous projects. Authorized by River and Harbor Act of June 14, 1880. For further details see page 1860 of Annual Report for 1915, and page 872 of Annual Report for 1938. Existing project. This provides for a project depth of 38 feet at mean low tide in the outer bar channel from that depth in the Gulf of Mexico to a point within the jetties; thence 36 feet in the authorized channels and basins to and including the upper turning basin about one-half mile below the Stauffer Chemical Co. plant, with two turning basins, one 700 by 700 feet at Brazosport and one 600 by 600 feet at the upper end of the channel, the channel to have a width of 300 feet seaward of the jettied entrance, 200 feet from the jettied entrance to the Brazosport turning basin, widened at the bend, and averaging 375 feet, thence to the upper turning basin; the widths in the approaches to the turning basins to converge within a distance of 800 feet from the width of the turning basin to the width of the channel; and for the extension of the channel with a depth of 30 feet and a width of 200 feet to and including a turning basin, 500 by 500 feet, near the Stauffer Chemical Co. plant at Freeport, when required in the interests of commerce and navigation. The work is to be accomplished as may be found desirable, by dredging, by jetties at the mouth of the harbor, and by a diversion dam in the Brazos River, a diversion channel, and necessary auxiliary works in general accordance with plan No. 6, as proposed by the district engineer, together with a lock in the diversion dam, approximately 200 feet long, 55 feet wide and 121/ feet deep over the miter sills. The River and Harbor Act of July 3, 1930, modified the act of March 3, 1925, so as to provide that when local interests shall have furnished assurances satisfactory to the Secretary of the Army that they will maintain the diversion channel, the United States shall assume the cost of maintenance of the navigable channel, estimated at $75,000 annually, including care and operation of the lock, if provided (Rivers and Harbors Committee Doc. 18, 70th Cong., 1st sess.). Under ordinary conditions the mean tidal range is about 1.5 feet and the extreme range about 21/2 feet. Freshets in the river, except under extreme conditions, do not cause a greater variation in the water surface than the tidal action. 718 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The estimated cost for new work is as follows: Federal (Corps of Engineers) $1,963,000 (July 1957), and non-Federal $858,300 (July 1957), including $758,300 contributed. The construction of a lock in the Brazos River diversion dam at cost of local interests and dredging upper one-half mile of 32-foot channel to vicinity of Stauffer Chemical plant portions of the project are considered to be inactive and are excluded from the foregoing cost estimates. The cost of these portions was last revised in July 1954 and was estimated to be $29,700 Federal costs and $1,299,700 local costs. The average annual maintenance cost during the past 5 years was $194,106. The existing project was authorized by the following: Acts Work authorized Documents Mar. 3, 1899 Dredging and such other work as may be deemed Specified in act. most effective in the judgment of the Secretary of War in improving and developing the harbor; for taking over the jetties and other privately built works at the mouth of the river.

Contains latest published maps. Recommended modifications. Under date of March 22, 1956, the Chief of Engineers recommended modification of the existing project to provide for relocation of the outer bar channel on a straight alinement with the jetty channel in lieu of the presently authorized channel, the realined channel to be 38 feet deep and 300 feet wide; and for maintenance of the Brazos Harbor channel and turning basin, as constructed by local interests, consisting of a channel 30 feet deep, 200 feet wide, and 2,790 feet long, flared at both ends, and extending from the existing Federal channel near the upper turning basin to a basin 30 feet deep, 550 feet wide, and 600 feet long, with such modifications thereof as in the discretion of the Chief of Engineers may be advisable. The estimated cost to the United States is $57,000 for construction, in addition to that already authorized, and $2,300 annually for maintenance in addition to that now required (H. Doc. 433, 84th Cong., 2d sess.). Local cooperation. All required local cooperation has been RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 719 fully complied with, except for the inactive portions and the requirements for work authorized by the River and Harbor Act of May 17, 1950 (H. Doc. 195, 81st Cong., 1st sess.). Terminal facilities. The terminal facilities consist of small privately owned wharves. Other facilities privately owned are 1 sulfur loading dock, 3 oil docks, an acid dock, 2 shell unloading docks, and 1 caustic dock. The present facilities are considered adequate for existing commerce. The Brazos River Harbor Navigation District opened in Decem- ber 1954 a 200- by 2,500-foot entrance channel to a 600- by 650- foot turning basin with a 650-foot steel and concrete dock and a 150- by 396-foot transit shed over rail facilities permitting all-weather work without damage to cargo. Operations and results during fiscal year. Maintenance: Con- dition surveys and miscellaneous inspections and reports were made at a cost of $3,007. Preliminary surveys, plans, and specifications for dredging from Brazosport turning basin to upper-turning basin were made at a cost of $1,858. Preliminary surveys, plans, and specifications for dredging the Sea Bar and Jetty Channel with U. S. Hopper Dredge A. Mackenzie were made at a cost of $2,284, and dredging was performed during the period April 18 to June 16, 1957 removing 1,210,700 cubic yards of material over a channel length of 16,400 linear feet at a cost of $144,734. The total cost of all work for fiscal year was $151,883. Condition at end of fiscal year. The existing project was 73 percent complete, exclusive of inactive portions. The existing project has been improved to a depth of 32 feet to and including the upper-turning basin. The work remaining consists of deepen- ing the 32-foot channel to and including the turning basin near Stauffer Chemical Co. plant and constructing a lock in the diver- sion dam in the old Brazos River, now considered to be inactive, and deepening the entrance channel to 38 feet and the remaining channels and basins to 36 feet to and including the upper turning basin. The controlling depths over a usable width at a mean low tide in the various channels and turning basins were as follows: Channel from deep water in the Gulf of Mexico to seaward end of jetty, 35.5 feet; channel from seaward end of jetty to Brazos- port turning basin, 33 feet; Brazoscort turning basin, 26 feet; channel from Brazosport turning basin to upper turning basin, 30 feet; upper turning basin 30 feet; channel from upper turning basin to Stauffer Chemical Co. plant, 19 feet; and turning basin at Stauffer Chemical Co. lant, 20 feet.

CHANNEL FROM PASS CAVALLO TO PORT LAVACA, TEX. Location. The bar at Pass Cavallo is 125 miles southwest of Galveston entrance and 54 miles north of Aransas Pass. Port Lavaca lies 26 miles to the northwest of the pass, across Mata- gorda and Lavaca Bays. (See U. S. Coast and Geodetic Survey Chart No. 1117.) Existing project. This provides for a depth of 9 feet and a width of 100 feet from Lynns Bayou at Port Lavaca, Tex., to deep water in Matagorda Bay near Port O'Connor, Tex., a distance of about 11 miles; for a channel 6 feet deep and 100 feet wide from Port Lavaca via Lavaca Bay, Lavaca and Navidad Rivers to Red Bluff about mile 3 on the Navidad River, a total distance of 20 miles; and for a harbor of refuge 9 feet deep near Port Lavaca with an approach channel 9 feet deep and 100 feet wide. Under ordinary conditions the mean tidal range is about 1 foot and the extreme range about 2 feet. The height of tide is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimated cost for new work is as follows: Federal (Corps of Engineers) $642,000 (July 1957), and non-Federal $280,000 (July 1957), including $77,000 contributed funds. The average annual maintenance cost during the past 5 years was $19,818.

RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 721 Recommended modification. Under date of February 15, 1956, the Chief of Engineers recommended that the existing project be incorporated into another project now being recommended, which would be designated as the Matagorda Bay Ship Channel. This ship channel project would provide for a deep-draft navigation channel from the Gulf of Mexico through Pass Cavallo to and in- cluding a turning basin at Point Comfort, Tex. consisting of an outer bar and jetty channel, 38 feet deep, 300 feet wide and about 6 miles long, from the Gulf through Pass Cavallo; an inner channel 36 feet deep, 200 feet wide and about 22 miles long across Matagorda and Lavaca Bays to Point Comfort, Tex.; a turning basin at Point Comfort 36 feet deep and 1,000 feet square; and dual jetties at the entrance, the southwest jetty extending to the 16-foot depth in the Gulf and the northwest jetty extending to the 24-foot depth; with such modifications thereof as in the discretion of the Chief of Engineers may be advisable. The estimated cost to the United States is $9,641,000 for construction, and $381,000 annually for maintenance in addition to costs now required (H. Doc. 388, 84th Cong., 2d sess.). The estimated cost to local interests is $7,280,000. Under date of October 28, 1954 the Chief of Engineers recom- mended that the existing project for the channel from Pass Cavallo to Port Lavaca be modified to provide for a depth of 12 feet and a width of 125 feet in the channel from the 12-foot depth in Matagorda Bay to the Turning Basin at Port Lavaca, a distance of 13.2 miles, and in the authorized channel to the harbor of refuge near Port Lavaca, a distance of 2.1 miles; for a depth of 12 feet in the harbor of refuge and the turning basin with the Federal Government assuming the maintenance of the latter; and that no dredging be done within 50 feet of any existing pierhead, or established pierhead line, or any wharf or structure; and with such modifications thereof as in the discretion of the Chief of En- gineers may be advisable; at an estimated cost to the United States of $316,000 for new work and $17,800 annually for maintenance in addition to that now required (H. Doc. 131, 84th Cong., 1st sess.). Local cooperation. Under the River and Harbor Act of March 2, 1945, local interests are required to furnish, free of cost to the United States, all necessary land, easements, and rights-of-way and suitable spoil-disposal areas for the initial construction and subsequent maintenance when and as required; hold and save the United States free from damages that may result from the con- struction and maintenance of the project; and provide necessary mooring facilities to which all vessels shall have free and equal access during storm periods, none of which has been complied with except for assurances to hold and save the United States free from claims for damages in connection with construction of the channel to Red Bluff, forwarded to Chief of Engineers for approval on June 29, 1955. Requirements under prior acts have been complied with. Terminal facilities. The terminal facilities consist of several privately owned piers and three privately owned slips at Port 722 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 Lavaca, and a municipally owned wharf, turning basin, one oil dock, and refrigerated-seafood processing and packing plant at the mouth of Lynns Bayou. The municipally owned facilities are open to the general public and are adequate for existing commerce. In addition, there is a privately owned channel, turning basin with private wharves, oil dock, and loading facilities owned by Aluminum Co. of America at Point Comfort, Tex. Operations and results during fiscal year. New work: Pre- liminary surveys, plans, and specifications were made for dredging an extension channel to Red Bluff at a cost of $2,057, and work under the contract was performed during the period December 14, 1956 to April 18, 1957 removing 945,277 cubic yards of material over a channel length of 55,435 linear feet at a cost of $132,536, and in addition $72,055 was expended from contributed funds. Maintenance: Condition surveys and miscellaneous inspections and reports were made at a cost of $81. Preliminary surveys, plans, and specifications were made for dredging from Lynns Bayou to Magnolia Beach at a cost of $1,666 and work under contract was peformed during the period December 13, 1956 to March 1, 1957, removing 429,931 cubic yards of material over a channel length of 35,500 linear feet at a cost of $55,252. The total cost for all work for fiscal year was $263,647, of which $206,648 was for new work, consisting of $134,593, Federal funds, and $72,055, contributed funds, and $56,999 was for maintenance. Condition at end of fiscal year. The existing project was about 47 percent complete. The channel from the 9-foot contour in Matagorda Bay to the mouth of Lynns Bayou was completed in 1939, and the 6-foot channel extending through Lavaca Bay and the Lavaca and Navidad Rivers to Red Bluff was completed in 1957. The work remaining consists of dredging the harbor of refuge and approach channel at Port Lavaca after being re- studied. The controlling depth over a usable width at mean low water to Port Lavaca was 9.0 feet and in the extension channel to Red Bluff was 7.0 feet. The total cost of the existing project to June 30, 1957 was $796,159, of which $336,550 was for new work consisting of $264,495 Federal funds and $72,055 contributed funds, and $459,609 was for maintenance.

RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 723 11. LITTLE BAY, TEX. Location. The improvements authorized in the vicinity of Little Bay are located adjacent to the town of Fulton, Tex., which is on the west shore of Aransas Bay, on the south central coast of Texas, 30 miles northeast of Corpus Christi, Tex., and 3 miles northeast of Rockport, Tex. Existing project. This provides for an entrance channel 8 feet deep at mean low tide and 100 feet wide extending from that depth in Aransas Bay to a turning basin 8 feet deep at mean low tide, 200 feet wide and 1,400 feet long opposite the town of Fulton, Tex.; and for a protective dike on the north side of the basin, 1,000 feet long, connecting the north end of the existing breakwater with the shore of Aransas Bay. Under ordinary conditions the mean tidal range in Aransas Bay is about 1 foot and the extreme range about 2 feet. The height of tide is dependent largely on the wind and, during strong "northers" in the winter season, the water surface may be depressed as much as 3 feet below mean low tide, while hurricanes have raised the surface as much as 12 feet above mean low tide. The Aransas County Navigation District, Rockport, Tex., con- structed the improvements in Little Bay at Fulton, Tex., as authorized by the River and Harbor Act of May 17, 1950 (H. Doc. 114, 81st Cong., 1st sess.). The work was performed from April 1, 1955 to December 21, 1955 under Department of the Army Permit No. W-N-243-41-Permit-3035, at an approximate cost of $32,300. Local cooperation. Fully complied with. Terminal facilities. The existing terminal facilities consist of several privately owned wharves adjacent to seafood processing houses. The Aransas County Navigation District No. 1 owns in fee simple title ample waterfront areas with bulkheads for docking vessels and is open to all on equal terms. In addition, the Naviga- tion District owns an ample number of boat stalls to accommodate all vessels operating from this terminal. Operations and results during fiscal year. Maintenance: Con- dition surveys and miscellaneous inspections and reports were made at a cost of $630. The total cost for all work for fiscal year was $630. Condition at end of fiscal year. The Aransas County Naviga- tion District, Rockport, Tex., constructed the improvements in Little Bay at Fulton, Tex., as authorized by the River and Harbor Act of May 17, 1950 (H.

The controlling depths at mean low tide were about 8 feet in the entrance channel and about 9 feet in the turning basin. 12. PORT ARANSAS-CORPUS CHRISTI WATERWAY, TEX. Location. This is a consolidation of the old improvements of Port Aransas, Tex., and the channel from Aransas Pass to Corpus Christi, Tex. Aransas Pass is on the southern portion of the coast of Texas, 180 miles southwest of Galveston and 132 miles north of the mouth of the Rio Grande. Aransas Pass connects Corpus Christi Bay and Aransas Bay with the Gulf of Mexico. The waterway extends from deep water in the Gulf through the Aransas Pass jettied entrance, thence westerly 203/4 miles to and including a turning basin at Corpus Christi, thence westerly 13/4 miles through the Industrial Canal to and including the turning basin at Avery Point, thence westerly 41/4 miles to and including a turning basin near Tule Lake. (See U. S. Coast and Geodetic Survey Charts Nos. 523, 1285, and 1286.) Previous projects. The original project for improvement of Aransas Pass (Port Aransas) was authorized by the River and Harbor Act of March 3, 1879. The improvement was taken over by the Aransas Pass Harbor Co. on June 30, 1890, under authority of the act of May 12, 1890. This company relinquished its rights to the United States on March 27, 1899. The channel from Aran- sas Pass to Corpus Christi was first improved under the River and Harbor Acts of March 2, 1907, and June 25, 1910. For further details, see page 1861 of Annual Report for 1915 and page 877 of Annual Report for 1938. Existing project.

S. ARMY, 1957 Mustang Islands, the project lengths of which are 9,240 and 7,385 feet, respectively. The project further provides for a stone dike on St. Joseph Island about 19,100 feet long connecting with the north jetty and extending up this island to prevent a channel being cut around the jetty. Under ordinary conditions, the mean tidal range at Aransas Pass is about 1.1 feet and the extreme range about 2 feet, and at Corpus Christi the mean range about 1 foot and the extreme about 11 feet. The heights of tides are dependent largely on the strength and directions of winds, and during strong "northers" in the winter season the water surface may be depressed as much as 3 feet below mean low gulf level. The estimated cost for new work is as follows: Federal (Corps of Engineers) $14,108,000 (July 1957), exclusive of amount ex- pended on previous projects, and non-Federal $5,932,000 (July 1957), including $2,621,000 contributed funds and value of useful work performed. The extension of the north jetty 1,950 feet and the south jetty 1,265 feet and the extension of the Inner Basin at Harbor Island 2,000 feet by 650 feet portions of the project are considered inactive and are excluded from the foregoing cost estimate. The cost of these portions was last revised in July 1954 and was estimated to be $21,351,000. The average annual maintenance cost during the past 5 years was $717,409. Recommended Modification. Under date of March 6, 1956, the Chief of Engineers recommended modification of the existing proj- ect to provide for dimensions in the project channel to La Quinta as follows: A depth of 36 feet in the channel and turning basin; a width of 200 feet in the channel, suitably widened on curves, and width of 300 feet in the reach between the north curve and the turning basin; a width of 1,000 feet and length of 800 feet in the turning basin; and a flared entrance to the channel and rectifica- tion of the south curve; all at an estimated first cost to the United States of $857,000 for new work and an increase of $17,000 in the approved cost of annual maintenance. (Report sent to Congress April 15, 1957, not yet printed.) Local cooperation. Fully complied with except for the provi- sions of the River and Harbor Acts of June 30, 1948, and Sentem- ber 3, 1954, local interests being required to furnish, free of cost to the United States, all necessary lands, easements, rights-of-way, and suitable spoil-disposal areas for the initial work and for sub- sequent maintenance as and when required; hold and save the United States free from damages that may result from construc- tion and maintenance of the project: accomplish without cost to the United States the alteration of pipeline and cable crossings on the rights-of-way and the removal of buildings, structures, and a por- tion of the rubblemound breakwater on the right-of-way for the 400-foot entrance channel into the Corpus Christi turning basin; provide and maintain without cost to the United States adequate mooring facilities within the anchorage basin at Port Aransas and a nublic landing which shall be open to all on equal terms; and contribute in cash 50 percent of the cost of constructing the branch RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 727 channel to and turning basin in the vicinity of La Quinta, none of which has been complied with except local interests have furnished the required assurances for construction of the branch channel to La Quinta, accepted on April 9, 1955, and have expended $1,200,000 on construction of the project in lieu of a cash contribution. Terminal facilities. Terminal facilities located on Harbor Is- land at the head of Aransas Pass, Ingleside, Corpus Christi, La Quinta, and Avery Point are considered adequate for existing com- merce.

BRAZOS ISLAND HARBOR, TEX. Location. At the extreme south end of the coast of Texas, about 7 miles north of the mouth of the Rio Grande, and about 125 miles south of Port Aransas. The harbor is at the inner end of Brazos Santiago Pass, which lies between Brazos and Padre Islands, and is the natural outlet from the Laguna Madre to the Gulf of Mexico. (See U. S. Coast and Geodetic Survey Chart No. 1288.) Previous projects. Authorized by River and Harbor Acts of June 18, 1878, March 3, 1881, and March 2, 1919. For further details, see page 1017, Annual Report for 1932, and page 882, Annual Report for 1938. Existing project. This provides for depths of 38 feet in the channel from deep water in the Gulf of Mexico through Brazos Santiago Pass and 36 feet in all other channels and basins; and widths of 300 feet in the channel from deep water in the Gulf of Mexico through Brazos Santiago Pass, 200 feet in the channel RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 731 across Laguna Madre, 200 feet in the Port Isabel Channel includ- ing the "wye" junction with the Brownsville Channel, 200 feet in the Brownsville Channel for a distance of about 12.6 miles and 300 feet for a distance of about 1.4 miles; from 550 feet to 1,000 feet in the Brownsville turning basin from this point for a distance of 2,640 feet over a bottom width varying from 550 feet to 1,000 feet ; for a small boat basin 12 feet deep, 300 feet wide and 1,500 feet in length with a connecting channel 12 feet deep and 125 feet wide adjacent to the existing Brownsville Channel; and for 36 feet in the Port Isabel turning basin for a distance of 2,900 feet over a bottom width varying from 200 feet at its entrance to 1,000 feet, connecting with the existing turning basin. All depths refer to mean low tide. The project also provides for two jetties at the Brazos Santiago Pass entrance. Under ordinary conditions the mean tidal range is about 11/2 feet and the extreme range is about 2 feet. The height of the tides is dependent, to some extent on the wind, and during strong "northers" in the winter season the water surface in the southern end of the Laguna Madre may be raised 4 feet or more above the mean low tide in the Gulf. The estimated cost for new work is as follows: Federal (Corps of Engineers) $10,970,000 (July 1957), exclusive of amount ex- pended on previous projects, and non-Federal $2,046,000 (July 1957), including $1,683,300 contributed. The average annual maintenance cost during the past 5 years was $384,160.

The obstructive bridge to be replaced is located over the entrance channel to the main turning basin of the Port Aran- sas-Corpus Christi Waterway, Tex., at Corpus Christi, Tex. The new bridge will be located over the Tule Lake extension of the Port Aransas-Corpus Christi Waterway about 41/2 miles up channel from the present bridge. ALTERATION OF BRIDGES-GALVESTON, TEX., DISTRICT 737 Existing project. The existing project provides for the reloca- tion of the existing bascule bridge at Corpus Christi, Tex., with a vertical-lift type bridge over the Tule Lake extension. The existing bascule bridge accommodates a single-track railway and 2- lane highway with a limited horizontal clearance of 97.6 feet and being critically located has become unreasonably obstructive to marine and vehicular traffic. To avoid the critical location, the bridge will be replaced by a new vertical-lift bridge of like capacity upchannel across the Tule Lake extension about 41/2 miles where marine traffic is considerably less dense. The new bridge will pro- vide for an ultimate channel width of 300 feet and a vertical clearance of 138 feet at mean high water. Under ordinary conditions the mean tidal range at Corpus Christi and in the Tule Lake extension is about 1 foot and the extreme about 11/2 feet. The estimated cost to construct the new bridge is $4,790,000 (July 1957), exclusive of $1,780,000 non-Federal costs. The existing project was authorized under the provisions of the Truman-Hobbs Act dated June 21, 1940. Local cooperation. Not applicable since the bridge construction is not a local cooperation project. However, under the provisions of the Truman-Hobbs Act, the bridgeowner is required to pay a pro rata portion of the approved apportionment schedule of costs. Operations and results during fiscal year. A contract was awarded on February 8, 1956, by the City of Corpus Christi, bridge-owner, for the construction of substructure and fenders for the new bridge. The contract is scheduled to be completed in Sep- tember 1957. Work under this contract was performed during fiscal year 1957 at a cost of $374,715. A contract for the super- structure portion of the bridge was awarded on September 28, 1956 in the amount of $2,197,358. Steel shortage has delayed start of construction on the superstructure. Steel shipment is expected to arrive at the job site by November 1957. Total Federal cost for the fiscal year was $374,715. Condition at end of fiscal year. The existing project was approximately 11 percent complete.

BUFFALO BAYOU, TEX. Location. These improvements are located on Buffalo Bayou, a tributary of the San Jacinto River, in Harris County, west and northwest of the city of Houston, Tex. (See U. S. G. S. quadrangle sheets for Harris County.) Existing project. The authorized plan provides for the im- provement of Buffalo Bayou and its tributaries above the turning basin (Houston) of the Houston Ship Channel to control floods for the protection of the city of Houston, and to prevent the deposition of silt in the turning basin of the ship channel by construction of detention reservoirs, enlargement and rectification of channels and construction of control works. The estimated cost for new work is as follows: Federal (Corps of Engineers) $50,230,000 (July 1957) and non-Federal $41,000,- 000 (July 1957). The average annual Federal maintenance cost during the past 5 years was $71,300 and non-Federal $115,000 (July 1956). The existing project was authorized by Flood Control Acts ap- proved August 11, 1939, and September 3, 1954 (H. Doc. 250, 83d Cong., 2d sess.), which provided, in lieu of the features authorized by the River and Harbor Act approved June 20, 1938 (H. Doc. 456, 75th Cong., 2d sess.), for Barker and Addicks Reservoirs on Buf- falo Bayou and for clearing, straightening, enlarging, and lining where necessary the channels of Buffalo, Brays, and White Oak Bayous. Barker and Addicks dams control 150 and 129 square miles, respectively. Barker Dam is an earthfill detention dam 71,900 feet long, including outlet works, and approximately 37 feet high, with a reservoir capacity of 207,000 acre-feet. Addicks Dam is an earthfill detention dam 61,166 feet long, including outlet works, and approximately 49 feet high, with a reservoir capacity of 204,- 500 acre-feet. Each dam has outlet works consisting of three gated and two ungated culverts. Local cooperation. The River and Harbor Act of September 3, 1954, requires that responsible interests give assurances satis- factory to the Secretary of the Army that they will furnish with- out cost to the United States all necessary lands, easements, rights- of-way. and spoil-disposal areas required for construction of the channel improvements and reimburse the United States for the cost of lands for the existing rectified channel below Addicks and Barker reservoirs; bear the cost of all highway bridge, utility, and sewer changes required for the improvements; hold and save the United States free from damages due to the construction works; maintain and operate all of the channel improvements after com- pletion, including the existing 7.4 miles of channel rectification works below Addicks and Barker reservoirs, in accordance with FLOOD CONTROL--GALVESTON, TEX., DISTRICT 739 regulations prescribed by the Secretary of the Army, except such dredging as may be required to maintain the desilting basin and the Federal navigation project in Buffalo Bayou; and establish and enforce building limit lines approved by the Secretary of the Army along all of the improved channels. None of these requirements have been formally complied with. However, local interests have established building limit lines along Buffalo Bayou and have re- moved encroachments from the floodway and have acquired about 50 percent of the lands needed for the improvement. In addition, local interests started a program in 1955 for reconstruction of highway bridges, utilities and sewer facilities. The offer of the Harris County flood control district to advance the sum of $2,900,- 000 to the Department for prosecution of the Buffalo Bayou proj- ect was accepted by the Secretary of War, and $2,500,000 was ac- cepted on December 18, 1940, $400,000 on July 10, 1945, and $1,- 500,000 on March 5, 1956. $4,400,000 was refunded to the Harris County Flood Control District in September 1956. Operations and results during fiscal year. New Work: Defi- ciency payments totalling $555.00 were made in acquiring two tracts of land on the Buffalo Bayou rectified channel and one tract of land at Barker Reservoir. Advance planning for channel rectification at White Oak Bayou was performed at a cost of $1,753. Advance planning and preliminary surveys for the Buffalo Bayou Rectified Channel were performed at a cost of $32,668. Channel rectification including design and supervision in Brays Bayou between the mouth and Chimney Rock Road (Mile 16.1) under three continuing contracts was performed during the fiscal year at a cost of $2,325,909. Maintenance: Routine operations, maintenance and care were carried on during the fiscal year at Barker and Addicks Reservoirs and the rectified channel at a cost of $46,399. Repair of fences at Barker and Addicks Reservoirs was performed with hired labor and Government furnished material during the fiscal year at a cost of $9,406. The total cost for maintenance of $55,805 does not include income in the amount of $8,201 expended during the fiscal year. The total cost of all work for fiscal year was $2,416,690 of which $2,360,885 was for new work and $55,805 was for maintenance. Condition at end of fiscal year. The existing project was about 28 percent complete. Construction of Barker Dam was completed in February 1945. Addicks Dam and 7.4 miles of channel rectification to South Canal were completed in October 1948. Land acquisition for Barker and Addicks Dams and channel rectification work was 99 percent complete. Work remaining consists of the completion of the design and construction of channel rectification for Brays, White Oak, and Buffalo Bayous. The total cost of the existing project to June 30, 1957 was $15,- 176,084, of which $14,273,829 was for new work and $902,255 was for maintenance. 740 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The Neches River has its source 60 miles southeast of Dallas and flows generally southeast 416 miles to Sabine Lake 4 miles east of Port Arthur, Tex. The Angelina River flows south- east 200 miles to its confluence with the Neches River 126 miles above its mouth. The authorized features are located as follows: Rockland Dam on Neches River approximately 3 miles west of Rockland, Tex.; McGee Bend Dam on Angelina River approxi- mately 10 miles northwest of Jasper, Tex.; Dam A on Neches River approximately 4 miles west of Horger, Tex.; Dam B on Neches River approximately one-half mile north of Town Bluff, Tex. (See U. S. Geological Survey Base Map, Northeast Texas, Scale 1 : 500,000.) Existing project. The plan of improvement provides for dams and reservoirs to be located at the Rockland and McGee Bend Dam sites on the Neches and Angelina Rivers, respectively, which will effect a large measure of flood protection to agricultural lands in the lower river valley and to the city of Beaumont, reduce the haz- ards to navigation resulting from floods, and provide a regulated flow in the lower river to supply municipal, agricultural, and in- dustrial demands. In addition, these proposed projects would permit the development of a large amount of firm power and afford opportunities for recreation. The plan also provides for construction of Dam A, located on the Neches River below Rockland Dam, for the development of power; and Dam B, located below the confluence of the Angelina and Neches Rivers, to regulate the daily fluctuations in discharge from the turbines in the upper projects and to develop a limited amount of power. Construction of Rockland and Dam A Reservoirs and of power facilities at Dam B is to be deferred until justified by future conditions. 1 Rockland McGee Bend Dam A 1 Dam B Stream__ ---.---- Neches-------.......

RIVERS AND HARBORS-FORT WORTH, TEX., DISTRICT 745 As itemized in the tables on page 744, the estimate of cost for new work, revised in 1957 for Dam B and McGee Bend Reservoirs and in 1954 for Dam A and Rockland Reservoirs, is $110,566,000 in- cluding $5,000,000 non-Federal costs. The flood-control works included in the comprehensive plan are listed on page 744. 2. McGEE BEND RESERVOIR, ANGELINA RIVER, TEX. Location. The improvement is located on the Angelina River 25.2 miles upstream from its confluence with the Neches River and about 10 miles northwest of Jasper, Tex. Existing project. The plan of improvement, a unit of the com- prehensive plan for flood control, water conservation, and hydro- electric power development in the Neches-Angelina Rivers Basin, provides for the construction of a rolled-earthfill embankment 11,300 feet in length, earthen dikes totaling 3,790 feet, an uncon- trolled concrete saddle spillway with a net length of 2200 feet, and a concrete non-overflow section 500 feet long, including power in- take and flood control outlets. The top of the dam will be about 120 feet above the river bed. The reservoir which will control 3,453 square miles of drainage area, will have a storage capacity of 4,040,800 acre-feet, including 1,148,900 acre-feet of flood control storage, 1,383,500 acre-feet of power storage, and 1,508,400 acre- feet of dead storage. The capacity of the initial installation of hydroelectric power generating facilities will be 45,000 kilowatts. The estimated cost of the project is $29,718,300 for construction and $23,281,700 for lands and damages, a total of $53,000,000 (July 1957), including $3,000,000 to be contributed by local interests. The existing project was authorized by the River and Harbor Act approved March 2, 1945 Public Law 14, 79th Cong., 1st sess.) in accordance with the plan of improvement outlined in Senate Document 98, 76th Congress, 1st session. Local cooperation. The project was adopted subject to the pro- vision that before construction is started upon any element, the State of Texas or other responsible local agency give assurances satisfactory to the Secretary of the Army that upon completion of the entire project it will contribute toward the first cost of the work the sum of $5,000,000. The Lower Neches Valley Authority has furnished assurances, which were accepted by the Assistant Secre- tary of the Army on November 13, 1947, that at any time after Congress appropriates sufficient funds for the construction of Dam B Reservoir, which by the addition of $2,000,000 would be suffi- cient to complete Dam B Reservoir, upon demand by the Secretary of the Army it will contribute $2 million toward the cost of con- struction of Dam B Reservoir; and upon completion of McGee Bend Reservoir on the Angelina River, it will contribute $3 million toward the first cost of the work.

CHAMITA RESERVOIR PROJECT, RIO CHAMA, N. MEX. Location. The Chamita Reservoir project is one unit of the flood-control phase of the comprehensive plan for the Rio Grande and tributaries, New Mexico. The authorized project provided for the construction of only 1 dam, a high dam, to be located at river mile 5 in Rio Arriba County about 6 miles northwest of Espanola, N. Mex.; however, on the basis of further studies and investigations, a substitute plan has been developed which is 782 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 composed of a combination of 2 dams, 1 of which is a low dam at the authorized Chamita site and the other a high dam at a site near Abiquiu, N. Mex. Both dam sites are located in Rio Arriba County, N. Mex., on Rio Chama, a tributary of the Rio Grande. Low Chamita Dam is approximately 5 miles upstream from the confluence of Rio Chama and Rio Grande, and is about 6 miles northwest of Espanola, N. Mex. Albiquiu Dam site, located near the town of Abiquiu, N. Mex., is about 25 miles upstream from the Chamita Dam site. The Abiquiu Dam will control 2,147 square miles and the Chamita Dam 979 square miles downstream from Abiquiu Dam, or a total of 3,126 square miles. (See U. S. Geological Survey map for plan and profile of Rio Chama, N. Mex., from mouth to mile 103, sheet 1.) The sub- stitute plan is considered to be the most economical and practical plan for protecting the Espanola and Middle Valleys of Rio Grande from sediment and floods originating in the Rio Chama watershed. It will also provide the same degree of protection as the authorized plan and will offer several distinct advantages, including a substantial saving in first cost. Existing project. The plan of improvement provides for con- struction of two dams for flood control and sediment storage as an aid in the prevention of flood damages and river sedimentation in Espanola and Middle Valleys of Rio Grande in New Mexico. Abiquiu Dam is an earthfill dam about 1,540 feet in length, rising 325 feet above streambed, with an outlet works, which pro- vides for controlled and uncontrolled releases of floodwaters. The controlled outlet consists of a 12-foot-diameter conduit with regulating gates, and the uncontrolled outlet consists of a separate 10-foot-diameter tunnel. The inlet to the uncontrolled outlet would be provided with a concrete ogee weir 16 feet high which limits the flood control and sedimentation reserve capacity of the reservoir to 562,000 acre-feet. After completion of Low Chamita Dam, the concrete weir at the inlet to the uncontrolled outlet would be removed which would reduce the flood and sedi- mentation reserve capacity of the reservoir to 449.000 acre-feet and limit the combined capacity of Abiquiu and Low Chamita Dams to 700.000 acre-feet for flood and sedimentation reserve. An uncontrolled spillway with bottom width of 25 feet would be located in a natural saddle about 1 mile north of the left abutment. The reservoir will have a canacity of 1,211,000 acre-feet at spillway crest. The uncontrolled outlet tunnel is provided in order to limit the reservoir storage to the required flood and sedimentation reserve capacities pursuant to the provisions of the authorizing legislation. Low Chamita Dam is an earthfill dam about 5,830 feet in leng'th, rising to a height of 153 feet above streambed, with an offchannel, uncontrolled, concrete-lined snillway, and an outlet works comprised of a gate structure, stilling basin, and a flood- control conduit 13 feet in diameter. The reservoir will have a storage canacitv at snillway crest of 251,000 acre-feet for flood control and sedimentation reserve. The estimated costs are as follows: FLOOD CONTROL-ALBUQUERQUE, N. MEX., DISTRICT 783 Abiquiu Dam: $1,770,000 for lands and damages and $17,630,000 for construction, a total of $19,400,000 (1957). Low Chamita Dam: $3,125,900 for lands and damages and $14,274,100 for construction, a total of $17,400,000 (1957). Total project cost (substitute plan-Abiquiu and Low Chamita Dams combined) : $4,895,900 for lands and damages and $31,904,100 for construction, a total of $36,800,000 (1957). The existing project was authorized by the Flood Control Acts approved June 30, 1948, and May 17, 1950. (See H. Doc. No. 243, 81st Cong., 1st sess., which contain the latest published maps.) Operations and results during fiscal year. Construction by contract of the controlled outlet tunnel and a portion of the relocation of State Highway No. 96 was commenced on August 24, 1956, and was about 50 percent complete on June 30, 1957. Engineering and design studies were continued. Model studies of the uncontrolled outlet were continued. The costs during the fiscal year were $2,492,812. Condition at the end of the fiscal year. Preconstruction plan- ning for Abiquiu Dam is complete. Planning of the entire Abiquiu project is approximately 79 percent complete. Pre- construction planning for Low Chamita Dam is 60 percent com- plete. Construction of Abiquiu Dam was initiated early in fiscal year 1957. Total costs under the existing project to June 30, 1957, were $3,406,932.

RIO GRANDE FLOODWAY, RIO GRANDE, N. MEX. Location. The project is located on the Rio Grande in New Mexico. It covers the section of the river commencing near Truth or Consequences (formerly Hot Springs) and going up- stream to the lower end of the Rio Grande Canyon, approximately 14 miles upstream from Espanola. Existing project. The plan of improvement provides for flood protection and major drainage improvements by channel rectifica- tion and levee enlargement and construction as a joint under- taking by the Bureau of Reclamation and the Corps of Engineers between river miles 123 and 394 (river mile 0 being at the inter- section of the New Mexico-Texas State line with the international boundary at El Paso). The portion to be accomplished by the FLOOD CONTROL--ALBUQUERQUE, N. MEX., DISTRICT 785 Corps of Engineers will consist of levee enlargement and con- struction, and bank protection work where necessary, to protect levees. Levees constructed by local interests now exist through the reach of the river involved, but are not uniform as to grade, section, or standard of construction and in many places are threatened by the meandering river channel. These levees will be modified and supplemented by additional levees where re- quired. The levees as modified or constructed will have a stand- ard section with a crown of 12 feet, 1 on 2.5 side slopes, and a freeboard of 4 feet above maximum water surface. Based on studies performed it is definitely known that the cost of the proposed work for the entire floodway, if accomplished to adequate standards, will exceed by several times the estimated cost as contained in the authorized plan. The authorized plan was predicated upon general investigations and local conditions prevailing in the mid-1940's; however, as a result of detailed engineering investigations and designs the plan has been ma- terially altered, taking into account recent local developments, and previously undisclosed foundation and seepage conditions. The character and amount of stabilization works have also been increased based upon further design studies and observation of the river's behavior. Since detailed plans and specifications and engineering and design studies are not sufficiently advanced, except for the Albuquerque Unit, to determine the quantities of work involved from which a realistic estimate of cost of the en- tire floodway can be determined, it was decided to initiate con- struction in the Albuquerque Unit first with funds appropriated for fiscal year 1953 and 1954 and initiate a review of the entire project with a view to development of a firm plan for the remain- der of the floodway. At the time this decision was made an estimate of $5 million (1954) was established for levee and flood control work in the Albuquerque Unit only. Several plans of improvement have been investigated; however, a firm plan has not been adopted. The current estimate of cost of the Albu- querque Unit is $3,155,000 (1957) including coordination of work of the Corps of Engineers with the United States Bureau of Reclamation during fiscal years 1956, 1957, and 1958. The project was authorized by the Flood Control Acts approved June 30, 1948, and May 17, 1950. (See H. Doc. No. 243, 81st Cong., 1st sess., which contains the latest published maps.) Local cooperation. In addition to the usual requirements, local interests must assume responsibility for all highway bridge and public utility relocations or replacements required. Operations and results during fiscal year. Construction by contract of Albuquerque Unit levees and bank stabilization, was completed on June 29, 1956. Necessary coordination of the work of the Corps of Engineers on the floodway with that of the United States Bureau of Reclamation was accomplished. Preparation of general design memorandum for the Cochiti to Rio Puerco Unit was initiated and was approximately 50 percent complete on June 30, 1957. The costs during the fiscal year were -$18,537. 786 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Condition at the end of the fiscal year. Construction of the Albuquerque unit was completed on June 29, 1956. Total costs under the existing projects to June 30, 1957, were $3,141,984.

ALBUQUERQUE DIVERSION CHANNELS, TRIBUTARIES OF RIO GRANDE, N. MEX. Location. The Albuquerque Diversion Channels project is located in the area which comprises the watersheds of the ephemeral streams entering a 15-mile reach of the Rio Grande from the east at Albuquerque, N. Mex., and vicinity. The com- bined drainage area of the tributaries is about 260 square miles. The Sandia Range of the Rocky Mountains, a prominent escarp- ment parallel to and about 12 miles east of the Rio Grande, forms the eastern border of the watersheds. The crest of this mountain range rises more than a mile in height above the river to an elevation of 10,692 feet above mean sea level. (See U. S. Geologi- cal Survey map, Albuquerque, N. Mex., quadrangle, 1: 62,500.) Existing project. There is a serious flood problem on the tributaries to the Rio Grande from the east in Bernalillo County, Albuquerque, N. Mex., and vicinity. There are no existing flood control works constructed by the Corps of Engineers on these tributaries. Flash floods originating on the steep slopes of the Sandia Range inundate large areas of the highly developed low- lands area adjacent to the river. As no adequate outlets to the river exist, the ponded waters remain until removed by seepage, evaporation, or by discharge through small irrigation ditches. The Heights area in eastern Albuquerque is a residential and business district. Embudo Arroyo flows through the northern part of the Heights and causes damage to street crossings and property. Campus Wash and several minor tributaries ori- ginating within the Heights also cause damage to streets and urban properties. The central business district, mainline and division shops of the Atchison, Topeka & Santa Fe Railway, Federal and State highways, commercial, industrial, residential, and suburban property in the lowlands are subject to flood damages. Floods also disrupt traffic on vital transcontinental rail lines and highways that traverse the lowlands area, and impounded waters create a serious health problem. FLOOD CONTROL-ALBUQUERQUE, N. MEX., DISTRICT 787 The authorized plan of improvement for flood control consists of the north diversion channel and south diversion channel lo- cated on high ground east of and parallel to the valley. The north diversion channel extends from Campus Wash north for about 9 miles and intercepts the discharge from the numerous arroyos north of United States Highway No. 66. The south diver- sion channel begins about one-half mile south of United States Highway No. 66, extends south for about 5 miles to intercept several minor arroyos, and merges with a channel in Tijeras Can- yon. The combined channels discharge into the Rio Grande through an outfall channel. The north and south diversion chan- nels are designed to carry floods equal in magnitude to the stand- ard project flood from all the tributaries. The estimated Federal cost is $9,637,800 for construction and $562,200 for relocations, a total of $10,200,000 (1957). The estimated non-Federal cost, including cash contribution of $282,000 for construction, is $5,076,000 (1957). Lands and damages costs are the responsibility of local interests. The existing project was authorized by the Flood Control Act of 1954, approved September 3, 1954. (See H. Doc. No. 464, 83d Cong., 2d sess., which contains the latest published maps.) Local cooperation. In addition to the usual requirements, local interests are required to make any alterations to existing improvements, other than railroads, which may be required and take steps to prevent further encroachment upon existing defined waterways of the tributaries by zoning or other means, or con- struct adequate waterways, or provide other drainage facilities to prevent the flood problem in the heights area of Albuquerque from developing into one of serious proportions. Local coopera- tion requirements also include cash contribution to cost of con- struction in lump-sum amounts equivalent to about 1.3 percent of the total first cost of the north diversion channel and about 3.4 percent of the total first cost of the south diversion channel. The total estimated cost to local interests, including cash con- tribution to the cost of construction proportional to the enhance- ment of land values in the protected areas, is $5,076,000 (1957). Local interests have organized the Sandia Conservancy District to cooperate with the Federal Government in the construction of the project, to construct complementary works, and plan and supervise flood plain zoning as required. A master plan has been approved and adopted. Appraisal of property has been initiated by a board of appraisers. The attitude of the property owners in general is favorable. Formal assurances will be requested in fiscal year 1958. Operations and results during fiscal year. Engineering and design studies were continued during the fiscal year. The costs during the fiscal year were $181,197. Condition at the end of the fiscal year. All planning is ap- proximately 45 percent complete. Preconstruction planning is about 90 percent complete. Total costs under the existing project to June 30, 1957, were $226,838. 788 REPORT OF THE CHIEF OF ENGINEERS, U. S.

LOS ESTEROS RESERVOIR AND MODIFICATION OF ALAMOGORDO DAM, PECOS RIVER, NEAR SANTA ROSA, N. MEX. Location. Los Esteros Dam is located in Guadalupe County, on the Pecos River, at river mile 776.4, approximately 7 miles north of Santa Rosa, N. Mex. Alamogordo Dam (existing) is located in Guadalupe County on the Pecos River, at river mile 710.8 about 21 miles upstream from Fort Sumner, N. Mex., and about 29 miles southeast of Santa Rosa, N. Mex. (See U. S. Geological Survey map, Corazon, N. Mex., sheet, scale 1: 125,000.) Existing project. The authorized plan of improvement pro- vides for construction of an earthfill dam 1,865 feet long with a maximum height of 218 feet above streambed for flood control, irrigation, possible municipal water supply, and sediment storage. An uncontrolled spillway 630 feet long will be located about 1,000 feet back from the left abutment and will be an unlined open rock cut. The outlet works, composed of a combination pressure tunnel and penstock with two 54-inch diameter balanced, free discharge valves will be located under the left abutment. An earthfill saddle dam 1,420 feet long and 12-foot maximum height will be located 4,000 feet back from the left abutment of the main dam. Storage capacity of the reservoir at spillway crest is 587,000 acre-feet, of which 60,000 acre-feet is allocated to sedi- mentation reserve, 250,000 acre-feet to irrigation and water sup- ply, and 277,000 acre-feet to flood control. Capacity of the reservoir at maximum pool level is 791,000 acre-feet. Area of the reservoir at spillway crest is 11,650 acres and at maximum pool level is 13,775 acres. The dam controls 2,479 square miles of drainage area. The authorized project also includes modification of existing Alamogordo Dam and Reservoir located on Pecos River (river mile 710.8) about 21 miles upstream from Fort Sumner, N. Mex., to exclusive flood-control use. Under the terms of the Pecos River compact and with the consent of the Carlsbad Irrigation District, the irrigation storage from Alamogordo Reservoir will be transferred to Los Esteros Reservoir. The existing dam is an earth and rockfill structure composed of two sections: the main FLOOD CONTROL--ALBUQUERQUE, N. MEX., DISTRICT 789 dam and a dike section which extends from the main dam to the left abutment. The main dam is 148 feet in height and there is a 3-foot parapet wall on the crest of the dam. A concrete chute spillway controlled by three tainter gates is located in the right abutment. A small hydroelectric plant, with a capacity of 7.5 kv-a., supplies local power requirements at the dam. The reservoir is about 14 miles long, and has a capacity of about 128,000 acre-feet, considering the most recent estimate of displacement by sediment. To effect the change of Alamogordo Reservoir to exclusive flood-control use, the embankment will be raised 10.5 feet and an emergency spillway 500 feet long will be cut through the sandstone and shale ridge on the right abutment. Because the maximum water surface would be higher under the modified condition, the crest of the service spillway will be raised to limit the discharge to the existing capacity of the chute. The tainter gates and piers will be removed. Also the needle valves on the outlet works will be removed. The modified reservoir will have a capacity at service spillway crest of 93,500 acre-feet, and a capacity at maximum pool level of 210,000 acre-feet. Area of reservoir at service spillway crest will be 3,480 acres and at maximum pool level 6,350 acres. The storage capacity of Alamogordo Reservoir is diminishing annually at the rate of about 2,200 acre-feet by sedimentation and if operated under existing conditions will not be capable of supplying the full irrigation demand of the Carlsbad Irrigation District for more than 40 years. With the reservoir operated exclusively for flood control in combination with Los Esteros Dam, an appreciable amount of the sediment from the intervening area will be sluiced through, and therefore it is estimated that deposition of sediment will be reduced to an average of about 460 acre-feet annually. With the reduced rates of sediment deposi- tion and with the proposed modification to the dam and spillway, the Alamogordo Reservoir will be effective for flood control for 100 years. Modifications of Alamogordo Dam already completed by the United States Bureau of Reclamation consist of raising the dam to required height, modifying the service spillway for proper functioning due to increased height of dam, and construction of emergency spillway. Preliminary studies by the Corps indicate some minor changes in the modified service and emergency spill- ways may still be necessary to adequately comply with require- ments of the authorized project for flood control and irrigation. Modifications of the dam completed by U. S. Bureau of Reclama- tion have greatly increased the spillway capacity and will have the effect of greatly reducing the cost of the project to the Corps. Full extent of the reduction in cost, however, will not be known until general design studies are completed. The estimated Federal cost is $6,677,700 for Los Esteros Dam and Reservoir, plus $442,300 for lands and damages, and $1,080,000 for modification of Alamogordo Dam, a total of $8,200,000 (1957). There are no relocations involved. The 790 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 estimated annual cost of operation and maintenance is $32,400 (1957), and the Carlsbad Irrigation District will be responsible for additional maintenance costs estimated at $10,000, which is approximately equivalent to the amount they now pay toward the operation and maintenance of Alamogordo Dam. The project is a unit of the general comprehensive plan for flood control on Pecos River and tributaries, Tex. and N. Mex., authorized by the Flood Control Act of September 3, 1954 (sec. 203, Public Law 780, 83d Cong., 2d sess.). (See H. Doc. No. 339, 84th Cong., 2nd sess., which contains the latest published maps.) Local cooperation. In addition to first costs, operation and maintenance of both reservoirs will be the responsibility of the Federal Government; however, the Carlsbad Irrigation District will be required to contribute to operation and maintenance costs an annual amount equal to what they now pay toward Alamogordo Dam. The Carlsbad Irrigation District also will be required to agree to the use of Alamogordo Reservoir for flood-control pur- poses only, and because they will realize equivalent benefits from storage capacity in Los Esteros Reservoir, they will be required to continue to fullfill their repayment obligation. Studies are underway by the Engineering Advisory Committee and subcommittees of the Pecos River Compact Commission to determine the effects of project on water supply of Pecos River to assist the State of New Mexico in making arrangements for transfer of conservation storage for irrigation from Alamogordo Reservoir to Los Esteros Reservoir as stipulated in the authoriz- ing legislation. Participants in these studies include the En- gineering Advisors of New Mexico and Texas to the Pecos River Compact Commission, representatives of the Carlsbad Irrigation District (local interests-owners of Alamogordo Reservoir), Bureau of Reclamation, Corps of Engineers and United States Geological Survey. These studies are essentially complete, but conclusions have not been reached and arrangements have not been made for transfer of conservation storage for irrigation. Operations and results during fiscal year. Engineering and design studies were continued during the fiscal year. The Corps of Engineers participated in the studies to determine effects of the project on water supply of Pecos River to assist the State of New Mexico in making arrangements for transfer of con- servation storage for irrigation from Alamogordo Reservoir to Los Esteros Reservoir. The costs during the fiscal year were $26,631. 'Condition at the end of the fiscal year. The hydrology design memorandum is approximately 57 percent complete. Topographic survey of Los Esteros Reservoir was completed by contract dur- ing the fiscal year. All planning is approximately 16 percent complete.

TWO RIVERS RESERVOIR, RIO HONDO, NEAR ROSWELL, N. MEX. Location. Two Rivers Reservoir project is located about 12 miles southwest of Roswell, N. Mex., on the Rio Hondo. Rio Hondo is formed at the confluence of Rio Ruidoso and Rio Bonito, near the Village of Hondo, N. Mex., in the foothills region of Sierra Blanca in the southeastern part of Lincoln County, N. Mex., and flows in a general easterly direction to its confluence with Pecos River near Roswel, N. Mex. (See U. S. Geological Survey map, Hondo Reservoir quadrangle, scale 1: 24,000.) Existing project. The authorized project consists of two earthfill dams, Diamond "A" Dam on Rio Hondo at about river mile 36 and Rocky Dam on Rocky Arroyo at about river mile 14, which will form the Two Rivers Reservoir. Diamond "A" Dam is 106 feet high and 4,994 feet long and Rocky Dam is 120 feet high and 2,924 feet long. Topography of the site permits the use of 4 natural saddles in limestone on the rim of the reservoir for spillways, which have a total length of 2,375 feet. Three of the spillway saddles are between the dams and one is south of Rocky Dam. Outlet works structures will be provided in each dam with a gated structure at Diamond "A" Dam and an uncontrolled outlet at Rocky Dam. No provision is made for conservation storage or storage for any purpose except flood-control. Flood releases from Diamond "A" Dam will be controlled, insofar as possible, so that flows through Roswell will not exceed the channel capacity of Rio Hondo which is 1,000 c. f. s. The capacity of Two Rivers Reservoir at spillway crest is 207,500 acre-feet of which 6,000 acre-feet is provided for sedimentation reserve, but which will be utilized for flood-control until filled with sediment. The area at spillway crest is about 5,670 acres and at maximum pool level is 7,130 acres. The dam controls 1,009 square miles of drainage area on Rio Hondo and 75 square miles on Rocky Arroyo, or a total of 1,084 square miles. The estimated Federal cost is $6,500,000 (1957) all of which is for construction. Lands and damages costs are the responsibility of local interests. There are no relocations involved. The esti- mated annual cost of operation and maintenance is $44,500, of which $14,700 is the estimated cost to local interests and $29,800 is estimated Federal cost. 792 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The project is based on the interim report of the Chief of Engineers on Rio Hondo at Roswell, N. Mex., prepared under the authority for a report on Pecos River and tributaries, Tex. and N. Mex., granted by the Flood Control Act approved June 28, 1938. (See H. Doc. 436, 83d Cong., 2d sess., which contains the latest published maps.) The existing project was authorized by the Flood Control Act of September 3, 1954 (Public Law 780, 83d Cong., 2d sess.). Local cooperation. Since this is principally a local protection project, under the provision of the authorizing act no construction is to be started until local interests have furnished to the United States, in fee-simple title, all lands necessary for construction of the project; obtained the necessary rights-of-way for and con- structed an all-weather access road to the project area; and given assurances satisfactory to the Secretary of the Army that they will (a) maintain the access road after completion of the dams; (b) maintain the present channel capacities in Rio Hondo be- tween the dam site and mile 12, estimated at 1,000 c. f. s., and in Rocky Arroyo between the dam site and the mouth, estimated at 900 c. f. s.; and (c) hold and save the United States free from damages due to the construction, maintenance and operation of the project, including any effects on underground and surface water supplies in the Rio Hondo Basin and along the Pecos River. The total estimated cost to local interests, not including the cost of annual maintenance, is $130,000, of which amount $55,000 is for construction of access road and $75,000 for lands and rights-of-way. Chaves County and Roswell city officials have given their ap- proval of the project and indicated that they would assume the responsibilities of local cooperation at the proper time. Because of the damaging floods of October 1954, there is strong local support for the project. Operations and results during the fiscal year.

Total costs under the existing project to June 30, 1957, were $121,605. 10. ARTESIA DIVERSION CHANNEL, EAGLE CREEK, N. MEX. Location. The Artesia diversion channel project is located on Eagle Creek, a tributary of Pecos River, approximately 4 miles upstream from Artesia, Eddy. County, N. Mex. Existing project. The project will control the runoff from ap- proximately 182 square miles of the watershed of Eagle Creek and consists of a diversion levee about 5.7 miles long, with a maximum height of about 10 feet, which will intercept the flood- flows of Eagle Creek and divert them into Tumbleweed Draw, a tributary which enters Pecos River about 4 miles downstream from Artesia. It also involves the construction of a low water highway crossing about 2,000 feet long on United States High- way No. 285 and a new trestle and grade raise for the Atchison, Topeka & Santa Fe Railway crossing on Tumbleweed Draw south of Artesia to provide for flood flows which will be diverted from Eagle Creek. The estimated Federal cost is $720,000 (1957), all of which is for construction. Lands and damages costs are the responsibility of local interests. No relocations are involved. The estimated annual cost of operation and maintenance is $3,000 (1957), all of which is non-Federal cost for ordinary maintenance of the diversion levee. The project is a unit of the general comprehensive plan for flood control on Pecos River and tributaries, Texas and New Mexico, authorized by the Flood Control Act of September 3, 1954 (sec. 203, Public Law 780, 83d Cong., 2d sess.). (See H. Doc. No. 339, 84th Cong., 2d sess., which contains the latest published maps.) Local cooperation. In addition to the usual requirements, local interests must assume responsibility for making alterations to existing improvements, other than railroads, which are required because of the construction works. Resolution constituting re- quest for formal assurances of local cooperation was submitted to the city of Artesia on June 26, 1957, for execution. The total estimated cost to local interests, not including annual maintenance costs, is $300,000 (1957), of which amount $270,000 is for construction of a bridge on United States Highway No. 285, and $30,000 is for rights-of-way and flowage easements. Operations and results during fiscal year. Engineering and design studies were continued during the fiscal year. The costs during the fiscal year were $24,242. Condition at the end of the fiscal year. The hydrology and general design memorandums are complete. Field surveys are complete.

SCHEDULING OF FLOOD-CONTROL RESERVOIR OPERATIONS The Flood Control Act approved December 22, 1944, section 7, Public Law 534, 78th Congress, 2d session, authorized the Secre- tary of War to prescribe regulations for the use of storage al- located for flood control or navigation at all reservoirs constructed wholly or in part with Federal funds provided on the basis of such purposes, and the operation of any such project shall be in accordance with such regulations: Provided, That this section shall not apply to the Tennessee Valley Authority, except that in case of danger from floods on the Lower Ohio and Mississippi Rivers, the Tennessee Valley Authority is directed to regulate the release of water from the Tennessee River into the Ohio River in accordance with such instructions as may be issued by the War Department. Pursuant to this Act, expenditures were made during fiscal years 1952 through 1957 for scheduling of flood-control reservoir operations and the preparation of reservoir regulation manual for Platoro Dam, located on the Conejos River, near the Town of Platoro, Conejos County, Colo. Platoro Dam was authorized by the Congress in the Interior Appropriation Act of 1941 (Act of June 18, 1940, ch. 395, 54 Stat. 406). (See H. Doc. 693, 76th Cong., 3d sess.) Construction of the project was completed by the Bureau of Reclamation during fiscal year 1952. Flood-control regulation of Platoro Reservoir was accomplished during the period of May 29, 1957 through June 30, 1957. Costs during the fiscal year were $799. Total costs for all work under this heading to the end of the fiscal year were $18,075.

NAVIGATION FEATURES Location. The Arkansas River rises in the Rocky Mountains near Leadville, Colo., and flows southeastward for about 1,459 miles through the States of Colorado, Kansas, Oklahoma, and Arkansas to join the Mississippi River at a point about 575 miles above the Head of Passes, La. (See U. S. Geological Survey State maps, scale 1: 500,000.) Previous projects. Previous projects were adopted by the River and Harbor Acts of July 3, 1832, April 8, 1876, March 3, 1879, June 14, 1880, July 5, 1884, August 5, 1886, August 11, 1888, June 13, 1902, and March 2, 1907. For further details, see page 1066, Annual Report for 1932 and pages 744, 864, and 881, Annual Report for 1943. Existing project. The River and Harbor Act of July 24, 1946, approved the multiple-purpose plan recommended in the report of the Chief of Engineers dated September 20, 1945 (H. Doc. 758, 79th Cong., 2d sess.), and letter of the Chief of Engineers dated March 19, 1946, and limited appropriations thereunder to $55 million for initiation and partial accomplishment of the proj- ect. The Flood Control Act of June 30, 1948, increased the 797 798 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 authorization for appropriations by $1 million by authorization to construct, as an emergency measure, bank protection and con- trol works at Bradens Bend, Okla., thereby increasing the total authorization to $56 million. The River and Harbor and Flood Control Acts of May 17, 1950, increased the authorization for ap- propriations an additional $80 million or to a total of $136 million and modified the multiple-purpose plan and the general comprehensive plan for flood control by substitution of Keystone Reservoir, located on the Arkansas River 538.8 miles above the mouth, for the approved Mannford Reservoir on the Cimarron River and by deletion of the approved Blackburn and Taft Reser- voirs on the Arkansas River as recommended by the Chief of Engineers (S. Doc. 107, 81st Cong., 1st sess.). Details concerning the Keystone Reservoir are shown under flood control, Tulsa District. The existing project provides for improvement of the Arkansas River and tributaries by construction of coordinated develop- ments to serve navigation, produce hydroelectric power, afford additional flood control, and provide related benefits in connec- tion with other activities such as recreation and wildlife propa- gation. The navigation features provide for a channel 9 feet deep following generally the Verdigris River from Catoosa, Okla., 52 miles downstream to the Arkansas River; thence along the channel of the latter stream to mile 101.7 (1943 survey); thence by a land cut, designated as the North Bank Canal route, to the White River at mile 17.2; thence along the channel of the White River to mile 7.8; thence by landcut to the Mississippi River at a point about 590.5 miles above the Head of Passes, La. The waterway would be canalized throughout its length by 3 naviga- tion locks and dams on the Verdigris River and 12 navigation locks and dams, 3 navigation locks, 1 navigation dam, and 4 navi- gation and hydroelectric power dams downstream therefrom. The 4 navigation and power dams are the Webbers Falls, Short Mountain, Ozark, and Dardanelle projects. Lock chambers are 110 by 600 feet on the Arkansas and White Rivers and 83 by 600 feet on the Verdigris River. A minimum channel width of 150 feet is proposed for the Verdigris River section and 250 feet for the Arkansas and White River sections. The estimated Federal cost of the project (July 1957) is $770,300,000 for new work and is itemized in the following table: Estimated Feature Location 1 cost TULSA DISTRICT MAIN STEM RESERVOIRS Webbers Falls lock and dam-----------............

The existing project was authorized by the River and Harbor Act of July 24, 1946, as amended by the Flood Control Act of 800 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 June 30, 1948, and the Flood Control Act of May 17, 1950. (See H. Doc. 758, 79th Cong., 2d sess., which contains the latest published maps.) Local cooperation. Local interests are required to provide adequate terminal and transfer facilities for navigation and to bear the increased cost of maintenance and operation of all altered rail and highway routes, including bridges and appurtenances, utilities, and other existing improvements, other than federally owned. Terminal facilities. Terminal facilities along the Arkansas River consist of a paved bank slope, under municipal control, at Little Rock; privately owned log slips at sawmills and stave mills at Little Rock; and sand and gravel derricks and elevators at Van Buren, Dardanelle, Little Rock, and Pine Bluff. These facilities, which are adequate for existing commerce on the river, are located at or near rail connections. Operations and results during fiscal year. General studies for the multiple-purpose plan were resumed. Planning and con- struction of emergency bank protection and channel rectification were continued. Observation and study of bank caving conditions were continued and plans and specifications prepared for emer- gency bank-stabilization and channel-rectification works at specific localities. Planning for the Dardanelle Lock and Dam was con- tinued and construction of the right bank access road and service facilities was begun. A cooperative program was initiated with the United States Geological Survey for the study of ground water levels in the Arkansas River Valley. For details see individual reports on following pages. The costs during the fiscal year were $3,473,619, of which $3,413,017 was for new work and $60,602 was for maintenance. The costs for the new work include $249,630 for the Tulsa District, $2,047,083 for the Little Rock District, and $1,116,304 for the Vicksburg District. The maintenance costs include $58,402 for the Tulsa District, and $2,200 for the Vicksburg District. Condition at end of fiscal year. General studies for the develop- ment of the overall plan are under way. Planning is 20 percent complete for the Dardanelle Lock and Dam and 12 percent com- plete for Lock and Dam No. 7. Construction of the emergency bank stabilization and channel rectification is 93 percent complete, the completed work amounting to about 28 percent of that work for the existing project. Construction of the Dardanelle Lock and Dam is about 1 percent complete. For details see individual reports on the following pages.

This project is located on the left bank of the Black River in and adjacent to the eastern part of the city of Poplar Bluff, Butler County, Mo. (mile 210.9). (See U. S. Geological Survey map for Poplar Bluff, Mo., quadrangle, and Corps of Engineers map for Harviell, Mo. quadrangle.) Existing project. The project consists of a new compacted earthfill levee encircling that part of the city of Poplar Bluff lying east of the Black River. The levee begins at a point opposite Black River mile 211.8, extends southeastward along Palmer Slough and across the Missouri Pacific Railroad, then southward to Black River at mile 208.4, thence up the left bank of Black River and FLOOD CONTROL--LITTLE ROCK, ARK., DISTRICT 807 along the city waterfront to the point of beginning. The project includes construction of 3.9 miles of earthfill levee; raising of 0.5 mile of street to serve as levee; construction of 1 large drainage structure and 13 small culverts; and excavation of 0.7 mile of ditch along the riverside of the east levee. The levee has a 3-foot free- board above the flow line of a project flood as modified by Clear- water Reservoir and confined by the levee. The discharge of the modified project flood is 37,000 cubic feet per second. The project protects 410 acres within the city of Poplar Bluff and 310 acres adjacent thereto. This project is a modification of the original project plan and provides essentially the same degree of protection. The estimated Federal cost of the project (1957) is $306,000 for construction and the estimated cost to local interests for lands and damages is $59,000, a total of $365,000. The existing project was authorized by the Flood Control Act approved June 22, 1936. (See H. Doc. 102, 73d Cong., 1st sess.) Local cooperation. Assurances of local cooperation were sub- mitted by local interests and approved by the Secretary of War on June 2, 1947. All rights-of-way have been furnished.

WHITE RIVER BASIN, LITTLE ROCK DISTRICT Location. These improvements are located on the White River and tributaries thereof and are in the States of Arkansas and Missouri. More definite locations of the individual items are given in the following paragraph. Existing project. The Flood Control Act of June 28, 1938, ap- proved the general comprehensive plan for flood control and other purposes in the White River Basin, as set forth in Flood Control Committee Document 1, 75th Congress, 1st session, with such modifications thereof as in the discretion of the Secretary of War 808 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 and the Chief of Engineers may be advisable, and authorized the sum of $25 million for reservoirs, for the initation and partial accomplishment of the plan, the reservoirs to be selected and ap- proved by the Chief of Engineers. The Flood Control Act ap- proved August 18, 1941, authorized to be appropriated the sum of $24 million, in addition to previous authorizations, for the prosecu- tion of the comprehensive plan approved in the act of June 28, 1938, for the White River Basin in Missouri and Arkansas, includ- ing the projects for flood control and other purposes recommended by the Chief of Engineers in House Document 917, 76th Congress, 3d session, and the modifications in the Norfork Reservoir project recommended by the Chief of Engineers in House Document 290, 77th Congress, 1st session. The Flood Control Act approved De- cember 22, 1944, authorized to be appropriated the sum of $45 million, the Flood Control Act approved July 24, 1946, authorized to be appropriated the sum of $40 million, and the Flood Control Act ainroved May 17. 1950, authorized to be appropriated the sum of $35 million, in addition to previous authorizations, for the pros- ecution of the comprehensive plan. The Flood Control Act ap- proved September 3, 1954, modified the general comprehensive nlan to provide for the generation of power in conjunction with flood control at the Greers Ferry Reservoir and the addition of Beaver Reservoir for flood control, power generation, and other nurnoses, substantially as recommended by the Chief of Engineers in House Document 499, 83d Congress, 2d session. The reservoirs included in the comprehensive plan are listed on the following page: Beaver, Table Rock, Bull Shoals, Norfork, Clearwater, and Greers Ferry Reservoirs were selected and approved for construc- tion by the Chief of Engineers in accordance with the above au- thorizations and individual reports on the six reservoirs are given on the following pages. All costs for those reservoirs previously reported under the heading "White River Basin, Little Rock District" have been transferred to the individual reports. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. Stream gaging was continued. Four major rises occurred on the Upper White and North Fork Rivers during the fiscal year. Regulation of flow on the North Fork River in the Norfork Reservoir and on the Upper White River in the Bull Shoals-Table Rock Reservoir system during the fiscal year preventing flooding on an average of about 43,400 acres of improved land for each rise of which approximately 34,400 and 9,000 was credited to the Bull Shoals-Table Rock system and Nor- fork, respectively. Beginning on April 3 and continuing until July 1 a series of storms occurred over the Upper White River Basin which produced three major rises above Table Rock, Bull Shoals, and Norfork Dams. The storms which occurred during the latter part of May produced a flood with a natural peak flow of 115,000 c.f.s. at the Table Rock Dam on May 25.

S. ARMY,. 1957 monolith being at elevation 817.5 feet above mean sea level at the beginning of the April-May floods. The construction kept apace of the floods until the low monolith at elevation 885.0 feet above mean sea level was overtopped on May 26. The controlled outflow was about 27,000 c.f.s. on June 11 when the Table Rock Reservoir crested at elevation 896.2 feet above mean sea level, corresponding to 1,981,000 acre-feet of total storage. As a result of this, con- siderable flooding of rural areas was prevented between Table Rock Dam and the head of the Bull Shoals Reservoir as the chan- nel capacity is about 20,000 c.f.s. in this reach. Also considerable damage was prevented to recreational property along Lake Taney- como and urban property in Branson and Hollister, Missouri, where significant damage begins when the flow exceeds about 60,000 c.f.s. Branson and Hollister are located at the upper end of Lake Taneycomo and about 8 miles downstream from the Table Rock Dam. Without the Table Rock Dam, flooding of rural areas would have been considerably greater below the Bull Shoals Dam as approximately 1,750,000 acre-feet of the volume of these floods was in storage behind the Table Rock Dam at the time of the Bull Shoals crest (elevation 694.4) which was only 0.6 foot below the top of the spillway gates. The total volume in the Bull Shoals Reservoir at the crest was 5,364,700 acre-feet or 43,300 acre-feet less than that at the top of spillway gates (elevation 695). Flood modifications on the White River at Calico Rock 17 miles down- stream from the mouth of the North Fork and 59 miles down- stream from the Bull Shoals Dam and at Newport, 102 miles downstream from Calico Rock, are given in the tabulation on the preceding page. The pool elevation of the Norfork Reservoir at the beginning of the fiscal year was 549.58 feet above mean sea level, corresponding to 1,198,800 acre-feet of total storage. At the end of the fiscal year the pool elevation was 570.73 feet above mean sea level, cor- responding to 1,713,000 acre-feet of total storage. The maximum pool elevation during the fiscal year was 573.44 feet above mean sea level, corresponding to 1,788,900 acre-feet of total storage. The pool elevation of the Bull Shoals Reservoir at the beginning of the fiscal year was 654.80 feet above mean sea level, corresponding to 3,084,400 acre-feet of total storage; and at the end of the fiscal year was 693.29 feet above mean sea level, corresponding to 5,287,300 acre-feet of total storage. The maximum pool elevation during the fiscal year was 694.40 feet above mean sea level, corresponding to 5,365,400 acre-feet of total storage. There were no costs during the fiscal year. Condition at end of fiscal year. Planning is 57 percent complete for Water Valley Reservoir and 15 percent complete for Lone Rock Reservoir. The progress on projects selected for construction is given in individual reports. The total costs to the end of the year were $612,972 for new work. There have been no appropriations or costs since the fiscal year ending June 30, 1952. The estimated additional amount needed to be appropriated for completion of existing project is $53,597,028. FLOOD CONTROL--LITTLE ROCK, ARK., DISTRICT 811 5. BEAVER RESERVOIR, WHITE RIVER BASIN, ARK. Location. The Beaver Dam site is at mile 608.5 on the White River in Carroll County, Ark., 6 miles west of Eureka Springs, Ark., and 80 miles upstream from the Table Rock Dam site. (See sectional aeronautical chart, Tulsa sheet, scale 1: 500,000; U. S. Geological Survey map for Eureka Springs, Ark.-Mo., quad- rangle, scale 1: 125,000.) The reservoir will extend about 66 miles upstream from the dam in Carroll, Benton, and Washington Counties, Ark. Existing project. The project plan provides for construction of a dam 2,475 feet long consisting of a concrete gravity structure across the main part of the valley with a rolled-earthfill section on the left abutment, and a hydroelectric power generating plant. The concrete portion of the dam will be 1,229 feet long and 217 feet high above the streambed. It will include a spillway section 328 feet long which will be bridged for a roadway across the dam. Flow over the spillway will be controlled by seven tainter gates 40 feet wide and 32 feet high. Flow through the dam will be regu- lated by six 4- by 7-foot conduits equipped with hydraulically- operated slide gates. Flow to the powerhouse will be through two 18-foot diameter penstocks. The powerhouse at the base of the dam will contain two 32,000-kilowatt generating units. The switchyard will be located on the left bank downstream from the powerhouse. The reservoir formed by the Beaver Dam will be one unit of a comprehensive plan for flood control and other pur- poses in the White River Basin and will control the runoff from an area of 1,186 square miles. It will have a total storage capacity of 1,654,000 acre-feet, of which 308,000 will be for flood control and 1,346,000 will be for generation of hydroelectric power. The estimated cost of the project (July 1957) is $44,240,000 for construction and $2,460,000 for lands and damages, totaling $46,700,000. The existing project was authorized by the Flood Control Act approved September 3, 1954. (See H. Doc. 499, 83d Cong., 2d sess., which contains the latest published map.) Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938 applies. Operations and results during fiscal year. Planning of the proj- ect was continued. Work included studies for selection of the dam site and for determining the height and type of dam, and for ex- ploratory drilling by hired labor. Investigations were made for sources of soil borrow and concrete aggregates. The costs during the fiscal year were $181,388 for new work. Condition at end of fiscal year. Overall plannning of the project was about 9 percent complete at the end of the fiscal year. Construction has not begun.

TABLE ROCK RESERVOIR, WHITE RIVER BASIN, MO. Location. The Table Rock Dam site is at mile 528.8 on the White River in Taney County, Mo., about 8 miles upstream and southwest of Branson, Mo. (See sectional aeronautical chart, Tulsa sheet, scale 1: 500,000; Harrison sheet NJ15-11, Army Map Service series V502, scale 1 : 250,000; U. S. Geological Survey map for Forsyth, Mo., quadrangle, scale 1 : 125,000). From the dam the reservoir will extend westward into Stone and Barry Counties, Mo., and into Boone, Carroll, and Benton Counties, Ark. Existing project. The project comprises the construction of a dam 6,423 feet long and 252 feet in height above the streambed. The dam consists of a concrete-gravity structure across the main part of the valley with two rolled-earthfill abutment sections and a hydroelectric power generating plant. The concrete portion of the dam will be 1,602 feet long and 261 feet high above the lowest point of foundation. The left abutment embankment will be 3,798 feet long, with a maximum height of 172 feet. The right abut- ment embankment will be 1,023 feet long, with a maximum height of-35 feet. The concrete portion of the dam will include a spillway section 531 feet long which will be bridged for a roadway across the dam. The flow over the spillway will be controlled by 10 radial crest gates 45 feet wide and 37 feet high. Flow through the dam will be regulated by four 4- by 9-foot conduits equipped with hy- draulically operated slide gates. The total discharge capacity of the outlets will be 14,500 cubic feet per second with the reservoir filled to the top of flood-control pool, elevation 931. Flow to the powerplant will be through four 18-foot-diameter penstocks. The powerhouse at the downstream base of the dam will contain four 50,000-kilowatt generating units. The switchyard will be located on the left bank downstream from the powerhouse. The reservoir formed by the Table Rock Dam will be one unit of a comprehensive plan for flood control and other purposes in the White River Basin and will control the runoff from an area of 4,020 square miles. It will have a total storage capacity of about 3,462,000 acre-feet, of which 760,000 will be for flood control and 2,702,000 for the generation of hydroelectric power. The estimated cost of the project (July 1957) is $63,347,300 for FLOOD CONTROL--LITTLE ROCK, ARK., DISTRICT 813 construction and $6,252,700 for lands and damages, totaling $69,600,000.

The existing project which is a modification of a previously authorized flood-control project provides protection for approxi- mately 32,000 acres of rural land in three separate levee systems known as the Fourche Island levee, the Fourche Place levee, and the Woodson levee, by a levee having a 11/2 -foot freeboard above a confined flood profile based on a flow of 800,000 cubic feet per second in the Arkansas River. The modified project differs from the previously authorized project in that it provides a levee grade about 2 feet higher and a compacted earthfill embankment. The estimated Federal cost of the project (July 1957) is $1,375,151 for the construction and the estimated cost to local interests for lands and damages is $71,064, a total of $1,446,215. The existing project was authorized by section 3 of the Flood Control Act approved August 18, 1941, and modified by section 10 of the Flood Control Act approved December 22, 1944. (For latest printed maps, see H. Doc. 447, 78th Cong., 2d sess.) Local cooperation. Assurances of local cooperation were sub- mitted by local interests and approved by the Secretary of War on February 28, 1947. All rights-of-way have been furnished. Operations and results during fiscal year. Repair of a scour at the outlet end of the drainage structure in the levee at Pennington Bayou was completed by contract. A contract for repair of a section of the levee which was partly destroyed by a slide was awarded and partly completed but work was discontinued due to high water. The costs during the fiscal year were $9.936 for new work. Condition at end of fiscal year. Except for repair of the section of levee damaged by slide, the project is complete. The repair was 40 percent complete at the end of the fiscal year. Construction of FLOOD CONTROL-LITTLE ROCK, ARK., DISTRICT 823 the project was begun July 12, 1947, and completed October 21, 1953.

BLUE MOUNTAIN RESERVOIR, ARKANSAS RIVER BASIN, ARK. Location. The Blue Mountain Dam is located in Yell County, Ark., on the Petit Jean River about 74.4 miles above its confluence with the Arkansas River, and about 12 miles south of Paris, Logan County, Ark. Blue Mountain Reservoir extends westward from the dam into Logan County. (See U. S. Geological Survey map for Magazine, Ark., quadrangle, scale 1: 125,000.) Existing project. The project consists of an earthfill dam about 2,800 feet long and about 115 feet in height above the streambed. Outlet works consist of a gate-controlled, concrete- lined tunnel through the right abutment, discharges from which 824 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,. 1957 are directed back into the Petit Jean River at a point about 3,000 feet below the dam. An uncontrolled saddle spillway 150 feet long is located on the left abutment, about 1,200 feet downstream from the dam axis. The reservoir, which is one unit of a comprehensive plan for flood control and other purposes in the Arkansas River Basin, controls the runoff from an area of 488 square miles, or about 46 percent of the total drainage area of Petit Jean River. It provides storage capacity of 233,000 acre-feet for flood control, and 25,000 acre-feet is in a permanent pool for sedimentation reserve, and as a wildlife refuge, or a total of 258,000 acre-feet. The estimated cost of the project (July 1957) is $4,267,163 for construction and $545,887 for lands and damages, totaling $4,813,050. The average annual maintenance cost during the past 5 years was $52,815. The existing project was authorized by the Flood Control Act approved June 28, 1938. (See Flood Control Committee Doc. 1, 75th Cong., 1st sess.) Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938 applies. Operations and results during fiscal year. Ordinary operation and maintenance of the project were continued. Eleven notable rises occurred on the Petit Jean River during the fiscal year. Flooding was prevented on an average of about 1,310 acres of improved land for each flood. The results of flood regulation on the river stages at Danville are given in the following tabulation.

The balance unexpended June 30, 1957, including accounts receivable, $4,474, will be applied during the fiscal year 1958 to payment of outstanding liabilities and other expenses to be incurred under this heading. Additional funds in the amount of $25,000 can be profitably expended during the fiscal year 1958 for investigations. 21. RESEARCH AND DEVELOPMENT Ninety-three stream-gaging stations were operated during the fiscal year, 38 of which were operated cooperatively by the United States Geological Survey and the Corps of Engineers, and the remainder independently by one or the other of these agencies. Suspended sediment samples were collected at 40 stations during the fiscal year in cooperation with the United States Geological Survey and suspended loads were determined at certain stations. Approximately 120 rainfall and/or river reporting stations were operated in a cooperative program by the United States Weather Bureau and the Corps of Engineers for use in forecasting stream- flow for flood warning and operation of reservoir projects. Records also were collected at certain hydroclimatic rainfall stations under a cooperative program of the two agencies. General hydrologic studies relating to streamflow frequency and distribution were continued. The costs during the fiscal year were $1,966 for hydrologic studies.

Geological Survey map for Wichita, Kans., quadrangle, scale 1: 125,000.) Existing project. The project plan consists of a diversion channel and a system of levees to prevent flooding in the cities of Wichita and Valley Center, Kans., and environs, starting at a point 760 miles above the mouth of the Arkansas River and extending upstream about 33 miles. Under the plan Little Arkansas River is being diverted into the Arkansas River by means of a flood- way beginning at a point about 2 miles northwest of Valley Center and extending southward to the Arkansas River about 9 miles northwest of Witchita. The flows of Chisholm Creek and its middle and west branch tributaries will be collected by a system of levees and channels north of Wichita and diverted across the Little Arkansas River into the Arkansas River (at mile 780). The combined flows of the Little Arkansas River, Chisholm Creek, and Arkansas River will be confined and diverted to the west of the city by a floodway, with existing stream channels being utilized to carry floodflows to the limit of their capacity. This bypass floodway will begin at a point about 3.1 miles downstream from the Kansas State Highway No. 96 river crossing and will provide a channel having a normal bottom width of 80 feet and an average depth of 10.9 feet. Levees flanking the floodway will, in general, be spaced 900 feet center to center with an average height of 8.5 feet and a crown width of 8 feet or more. From the Arkansas River the floodway would extend southwest 2 miles to intercept Big Slough, along Big Slough for 5 miles, thence south and southeast 3 miles to intercept Cowskin Creek, along Cowskin Creek for 2 miles, thence east, and southeast about 5 miles entering the Arkansas River approximately 1 mile north- west of Derby, Kans. (at river mile 760). Existing levees and drainage canals previously constructed by local interests, are being enlarged, strengthened, or rectified as required. The com- pleted system with five control structures will provide about 91.2 miles of levee. The estimated Federal cost (July 1957) is $12,200,000 and the estimated non-Federal cost is $6,580,000. FLOOD CONTROL-TULSA, OKLA., DISTRICT 833 The existing project was authorized by the Flood Control Act, approved June 22, 1936. (See H. Doc. 308, 74th Cong., 1st sess., which contains the latest published maps.) Local cooperation. The city of Wichita has furnished assur- ances of local cooperation for the entire project which were approved by the Secretary of War on February 25, 1946. Right of entry has been granted for the entire project. Operations and results during the fiscal year. Construction of the project was continued from 61 percent completion to 81 per- cent completion. The work accomplished during the fiscal year consists of completion, by contract, of all railroad relocation and alteration work and channel construction work required for the Big Slough-Cowskin Floodway. Work was continued by contract on the Little Arkansas River Floodway diversion canal; the first segment was completed September 1956; and work on the final segment was started October 1, 1957 and continued to 82 percent completion. Construction of Chisholm Creek Diversion Canal was started on April 29, 1957 and continued to 9 percent completion by continuing contract. Railroad relocation work required for the Little Arkansas River Floodway and for the Chisholm Creek Diversion Canal was initiated and continued to 81 percent completion, by continuing contract. Owing to the desires of local interests, a pressure box culvert constructed for the Chisholm Creek Diversion Canal is being constructed on a reimbursable basis. This culvert is being constructed wide enough to accommodate relocation of United States Highway No. 81 and a Sedgwick County road in addition to providing a crossing for the Atcheson, Topeka and Santa Fe and St. Louis-San Francisco railroads. The costs during the fiscal year were $2,381,835 of which $2,341,635 was from regular new work funds and $40,200 was from special funds contributed for work desired by local interests. Condition at end of fiscal year. Construction by contract for clearing, snagging, widening, and otherwise improving the exist- ing East Branch interception canal and Witchita drainage canal was initiated in May 1950 and completed in August 1950. This portion of the project was transferred to the city of Wichita, Kans. on February 7, 1951, for future maintenance and operation. Construction was started in June 1950 on the Big Slough-Cowskin Floodway and completed May 29, 1957. The downstream portion of Parcel "A" of the Big Slough-Cowskin Floodway was accepted by the city of Wichita and Sedgwick County on January 2, 1957. Work is underway on the remaining useful units of the project. The little Arkansas River Floodway is 87 percent complete, the Chisholm Creek Diversion Canal is 11 percent complete and the work continues. The project as a whole is 81 percent complete. In general, the work required to complete the project in addition to the Little Arkansas River Floodway and the Chisholm Creek Diversion Canal consists of extension of riprap and construction of jetties along the main stem of the Arkansas River and general cleanup and seeding of spotted areas. The total costs to the end of the fiscal year were $9,923,066 of 834 REPORT OF THE CHIEF OF ENGINEERS, U. S.

FORT SUPPLY RESERVOIR, NORTH CANADIAN RIVER, OKLA. Location. Fort Supply Reservoir is located on Wolf Creek, a tributary of the North Canadian River, about 12 miles northwest of Woodward, Woodward County, Okla. (See sectional aeronautical chart, Wichita sheet, scale 1: 500,000.) Existing project. The plan of improvement consists of an earthfill dam and concrete spillway with a total length of 11,865 feet, rising 85 feet above the streambed, the reservoir providing for storage of 92,700 acre-feet for flood control and 13,400 acre- feet for a permanent pool for recreation and preservation of wild- life, or a total storage capacity of 106,100 acre-feet. The outlet works, consisting of a semielliptical conduit controlled by three 71/2- by 16-foot vertical-lift gates, and a stilling basin, are located in the left abutment. A concrete chute-type spillway, 540 feet long, controlled by a concrete weir at the upstream end, provides for the passage of floodflows around the left end of the dam. The reservoir controls 1,735 square miles, or practically the entire drainage area of Wolf Creek, and is operated as a unit of the coordinated reservoir system for flood control in the Arkansas River Basin. The estimated costs (July 1957) are $7,325,600 for construction and $245,000 for lands and damages, a total of $7,570,600. The average annual maintenance cost during the past 5 years was $52,926. FLOOD CONTROL--TULSA, OKLA., DISTRICT 835 The existing project was authorized by the Flood Control Act approved June 22, 1936. (See H. Doc. 308, 74th Cong., 1st sess.) Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during the fiscal year. All structures were operated and maintained in a serviceable condition through- out the year, by hired labor. The pool elevation at the beginning of the fiscal year was 2,002 feet above mean sea level, and the ele- vation at the end of the fiscal year was 2,021 feet. During May 1957, flood waters stored in the reservoir reduced the peak stage on North Canadian River at Woodward, Okla., 1.8 feet. The costs during the fiscal year were $50,618 for maintenance. Condition at end of fiscal year. Construction of the project is complete. Mobilization for construction was started in March 1938. After a construction camp had been built, actual work on the dam was started during October 1938, by contract. Four years later, the project was placed in operation. However, after the temporary office building had deteriorated, the last item of construction, consisting of erection of a prefabricated steel maintenance building, was completed on March 31, 1952, by hired labor. The project is complete except for additional public use facilities. The total cost of new work to the end of the fiscal year was $7,477,649, of which $7,390,611 was from regular funds and $87,038 was from emergency relief funds. The total cost accrued for maintenance was $715,527, all from regular funds.

OKLAHOMA CITY FLOODWAY, NORTH CANADIAN RIVER, OKLA. Location. The project is located on the North Canadian River at Oklahoma City, Okla. (See U. S. Geological Survey map, Chickasha, Okla., quadrangle, scale, 1: 125,000.) Existing project. The plan of improvement consists of an enlarged and straightened channel through the city, designed to carry 45,000 cubic feet per second. The improvement will be about 13.4 miles in length, beginning about 1 mile upstream from South May Avenue (river mile 273.7) and extending to the vicinity of Spencer, Okla. (river mile 257.5). The major part of the improvement will be about 13 feet deep and will have a bottom width of 425 feet. The side slopes will be lined with stone. Natural drainage ways will be modified to drain into the canal by the construction of 15 lateral drainage ditches. Excavated material will be placed in old channel and low areas. The estimated Federal cost (July 1957) is $8,300,000 and the non-Federal cost is $7,071,600. The project, as authorized by the Flood Control Act of July 24, 1946, was modified by the Flood Control Act, approved May 17, 1950, to provide for construction in accordance with the canal plan described above. Local cooperation. The city of Oklahoma has furnished assur- ances of local cooperation and rights-of-entry has been granted for the entire project. Operations and results during the fiscal year. Construction of the project was continued from 61 percent completion to 92 per- cent completion. All work on railroad facilities requiring altera- tion or relocation due to construction of the floodway was essentially completed by contract. Construction on the fourth segment of the floodway (vicinity of Robinson Avenue to the upper limits of the project) was continued from 10 percent com- pletion to 84 percent completion by continuing contract. On Janu- ary 7, 1957, work was started on the last major feature of the floodway which covers certain floodway laterals and gaps held in abeyance pending completion of bridge crossings downstream from Robinson Avenue. This work was carried to 37 percent completion at the end of the fiscal year and the work continues by continuing contract. In addition, a temporary low water crossing was constructed as desired by local interests owing to local interests' delay in construction of a highway bridge. The costs during the fiscal year were $2,106,146 of which 838 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 $2,101,429 was from regular new work funds and $4,717 was from special funds contributed for work desired by local interests. Condition at end of fiscal year. Construction of the project as a whole is 92 percent complete. That portion of the floodway downstream from 4th Street was accepted by the city of Oklahoma City during September 1955, for future operation and mainte- nance. Railroad relocation work initiated January 5, 1955 is 99 percent complete and floodway channel work initiated January 29, 1953 is 89 percent complete. This work has been accomplished under 19 separate contracts. In general, the work required to complete the project covers completion of the fourth segment of the floodway upstream from Robinson Avenue and completion of certain gaps and floodway laterals downstream from Robinson Avenue. The total costs to the end of the fiscal year were $7,608,962, of which $7,604,245 was from regular new work funds and $4,717 was from special contributed funds.

GREAT SALT PLAINS RESERVOIR, SALT FORK OF ARKANSAS RIVER, OKLA. Location. Great Salt Plains Reservoir is located on the Salt Fork of the Arkansas River 103.3 miles above its mouth, and about 12 miles east of Cherokee, Alfalfa County, Okla. (See sectional aeronautical chart, Wichita sheet, scale 1: 500,000.) Existing project. The plan of improvement consists of an earthfill dam and concrete spillway 6,010 feet long, rising 72 feet above the riverbed, with a reservoir providing for the storage of 245,300 acre-feet for flood control and 46,700 acre-feet for sedimentation reserve, recreation, and preservation of wildlife, or a total storage capacity of 292,000 acre-feet. A concrete cascade- type spillway 310 feet wide, containing 3 gravity-type concrete FLOOD CONTROL--TULSA, OKLA., DISTRICT 839 weirs, provides for the passage of floodflows around the right end of the dam into the river valley below. The outlet works consist of 4 ungated 10- by 12-foot conduits through the center section of the upper weir. The reservoir controls 3,200 square miles, and is operated as a unit of the coordinated reservoir system for flood control in the Arkansas River Basin. The estimated costs (July 1957) are $4,188,400 for construction and $488,800 for lands and damages, a total of $4,677,200. The average annual maintenance cost during the past 5 years was $46,868. The existing project was authorized by the Flood Control Act approved June 22, 1936. (See H. Doc. 308, 74th Cong., 1st sess., which contains the latest published maps.) Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. The project struc- tures were operated and maintained in a serviceable condition throughout the year, by hired labor. On three separate occasions during the spring of 1957 the reservoir was operated for storage of flood waters thereby reduc- ing the peak stage on Salt Fork of the Arkansas River at Tonkawa by 2.4, 5.4, and 0.2 feet. Peak crest on the Arkansas River at Tulsa was reduced by about 0.02 foot. The cost for maintenance during the fiscal year was $44,604. Condition at end of fiscal year. Construction of the project is complete. Mobilization for construction was started in May 1938. After a construction camp had been built, actual construction work on the dam was initiated in September 1938. The project was placed in operation during July 1941. No addi- tional new work construction is presently scheduled for this project except for additional public use facilities. The total cost of new work to the end of the fiscal year was $4,598,631, of which $4,573,887 was from regular funds and $24,744 was from emergency relief funds. The total cost of maintenance was $721,949, all from regular funds.

Keystone Dam is located on the main stem of the Arkansas River about 539 miles above its mouth, and about 2 840 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 miles downstream from the mouth of the Cimarron River near Keystone, Okla., and about 15 miles west of Tulsa, Okla. (See U. S. Geological Survey map for Hominy, Okla., quadrangle, scale 1: 125,000, Skedee and Yale, Okla., quadrangles, scale 1: 62,500.) Existing project. The plan of improvement consists of an earthfill dam and an integral gate-controlled concrete spillway of a total length of 4,570 feet and rising 121 feet above the streambed. The dam, which will form a reservoir with a total storage capacity of 1,879,000 acre-feet, includes provision in the structure for future installation of power facilities. Under an initial plan of operation 1,414,000 acre-feet of the storage is allo- cated for flood control and 465,000 acre-feet is set aside for conservation, water supply, and sedimentation reserve. The reservoir has a drainage area of 74,506 square miles and will be operated as a unit of the comprehensive plan for flood control in the Arkansas River Basin. The estimated costs (July 1957) are $39,535,626 for construc- tion and $97,464,374 for lands and damages, a total of $137,000,000. The existing project was authorized by the Flood Control Act approved May 17, 1950. (See S. Doc. 107, 81st Cong., 1st sess., which contains the latest published map.) Modification of the above plan to include the power aspects of the project authorization for operation of the reservoir as a unit in the multiple-purpose plan for Arkansas River and tributaries could be accomplished by addition of a powerhouse and attendant generating facilities at an increased cost (July 1955) of $15,000,000; however, under present criteria power is not justified at this time. The project would also serve as a unit of the authorized navigation plan for Arkansas River by retention of sediment in the reservoir. Local cooperation. Section 2 of the Flood Control Act, approved June 28, 1938, applies. Operations and results during the fiscal year.

POLECAT CREEK, OKLA. (HEYBURN RESERVOIR AND CHANNEL IMPROVEMENTS) Location. Polecat Creek is a minor tributary to the Arkansas River near Sapulpa, Creek County, Okla. (See U. S. Geological Survey maps for Nuyaka, Hominy, and Claremore, Okla., quadrangles, scale 1: 125,000.) Existing project. The plan of improvement consists of flood protection in the Polecat Creek Valley by means of a reservoir at mile 48.6, near Heyburn, Okla., which controls 123 square miles and channel improvements at Sapulpa on Rock Creek, its major tributary, and on Polecat Creek below the mouth of Rock Creek. The Heyburn Dam is an earthfill structure 2,920 feet long and rising 89 feet above the streambed with the reservoir providing a storage capacity of 49,500 acre-feet for flood control and 10,200 acre-feet for sedimentation reserve, recreation and preservation of wildlife, a total of 59,700 acre-feet. Outlet works consist of an uncontrolled circular drop inlet conduit. An uncontrolled saddle spillway, located about 1,000 feet west of the right abutment, pro- vides for the passage of floodflows into the river below. The channel of Rock Creek from mile 4.4 to the mouth has been cleared by removal of debris and about 1.3 miles of this length is deepened. The channel of Polecat Creek is cleared from the mouth of Rock Creek, mile 21.2 to the Arkansas River. The estimated Federal costs (July 1957) are $1,802,900 for construction, including $135,300 for construction of channel improvement on Polecat and Rock creeks, and $615,200 for lands and damages in the reservoir area, a total of $2,418,100. Esti- mated non-Federal costs are $113,000. The average annual maintenance cost during the past 5 years was $34,812. The existing project was authorized by the Flood Control Act approved July 24, 1946 (See H. Doc. 290, 80th Cong., 1st sess., which contains the latest published maps). Local cooperation.

Geological Survey map for Eureka, Kans., quadrangle, scale 1: 125,000.) Existing project. The plan of improvement consists of an earthfill dam and concrete spillway with a total length of about 6,015 feet and rising 94 feet above the streambed with a reservoir providing for the storage of 236,000 acre-feet for flood control and 27,000 acre-feet for water supply, pollution abatement, sedimenta- tion reserve, recreation, and preservation of wildlife, a total of 263,000 acre-feet. A concrete channel spillway, controlled by FLOOD CONTROL--TULSA, OKLA., DISTRICT 843 eight 50- by 25-foot gates on the weir crest, provides for passage of floodflows into the river valley below. The outlet works consist of seven 5- by 8.5-foot gated sluices through the spillway weir. The reservoir which controls 585 square miles is operated as a unit of the comprehensive reservoir system for flood control in the Arkansas River Basin. The costs were $8,505,261 for construction and $1,949,500 for lands and damages, a total of $10,454,761. The average annual maintenance cost during the past 5 years was $66,636. The existing project was authorized by the Flood Control Act approved August 18, 1941. (See H. Doc. 440, 76th Cong., 1st sess., which contains the latest published map.) Local cooperation. Section 2 of the Flood Control Act, approved June 28, 1938, applies. Operations and results during fiscal year. All project struc- tures were operated and maintained in a serviceable condition throughout the year, by hired labor. Six noteworthy rises occurred on Fall River above the Fall River Reservoir during the fiscal year. The pool elevation at the beginning of the fiscal year was 942.88 feet above mean sea level, corresponding to 15,000 acre-feet of total storage; and was 949.48 feet above mean sea level at the end of the fiscal year, correspond- ing to 30,000 acre-feet. The maximum pool elevation during the fiscal year was 967.47 feet, corresponding to 107,000 acre-feet of total storage.

OOLOGAH RESERVOIR, ARKANSAS RIVER BASIN, OKLA. Location. Oologah Reservoir is located on the Verdigris River 90 miles above its confluence with the Arkansas River and about 10 miles northwest of Claremore, Rogers County, Okla. (See U. S. Geological Survey maps for Claremore and Nowata, Okla., quadrangles, scale 1: 125,000.) Existing project. The plan of improvement provides for con- struction of an earthfill dam, 4,100 feet long and rising 129 feet above the riverbed. The reservoir would provide for 963,000 acre-feet for flood-control storage, 48,700 acre-feet for water sup- ply and 9,300 acre-feet for sedimentation reserve, a total of 1,021,000 acre-feet. Two gated concrete conduits will be con- structed through the embankment to form the outlet works. An off-channel uncontrolled saddle spillway about 2 miles east of the left abutment would provide for passage of floodwater into the valley below the dam. The reservoir, which will control 4,339 square miles, will be operated as a unit in the comprehensive plan of development of the Arkansas River Basin. The estimated costs (July 1957) for the initial development are $9,644,132 for construction and $21,755,868 for lands and damages, a total of $31,400,000. The above plan of improvement is adaptable for future modifi- cation to include additional storage by construction of a gated FLOOD CONTROL-TULSA, OKLA., DISTRICT 847 spillway, a dike east of the spillway, and additional reservoir clearing. Based on July 1956 estimates, the provision of additional storage would increase the cost of the project by $4,700,000.

Local cooperation. Section 2 of the Flood Control Act, approved June 28, 1938, applies. Operations and results during the fiscal year. Construction on the project as a whole was advanced 6 percent. First stage construction on the main dam embankment and excavation for outlet works, which started March 26, 1956, was continued from 21 percent to 72 percent completion, by continuing contract. Construction on project administration and maintenance building was continued to completion, by contract. On January 22, 1957 work was started by contract on construction of access road and excavation for an off-channel spillway and at the end of the fiscal year this work was 33 percent complete. Hired labor operations were continued during the fiscal year on engineering studies and preparation of contract plans and specifications, acquisition of reservoir lands and rights-of-way, and negotiations with owners of highways, railways, and pipeline facilities which require re- location or alteration. Owing to the desires of local interests, the access road under construction is being made wider than project requirements on a reimbursable basis. The costs during the fiscal year were $1,843,247 of which $1,835,147 was from regular new work funds and $8,100 was from special funds contributed for work desired by local interests. Condition at end of fiscal year. After the dam site had been acquired and right abutment access road constructed, the project was placed in a standby status during October 1951 in view of the intent of the Civil Functions Appropriation Act of 1952. How- ever, construction of the project was resumed in December 1955 and at the end of the fiscal year the project as a whole was 9 percent complete. Project administration and maintenance build- ing is complete and work continues on the first stage of the main dam and outlet works, access road to left abutment, and spillway excavation are underway. Contract plans for the second phase of the main dam embankment, outlet works and spillway are underway, as are contract plans for relocation of United States Highway Nos. 169 and 60, Oklahoma State Highway No. 28 and Missouri Pacific Railroad. Land acquisition for the entire reser- voir is 9 percent complete.

PENSACOLA RESERVOIR, ARKANSAS RIVER BASIN, OKLA. Location. Pensacola Dam is located on the Grand (Neosho) River, 77 miles above its mouth, and adjacent to the town of Dis- ney, Mayes County, Okla. (See U. S. Geological Survey maps for FLOOD CONTROL-TULSA, OKLA., DISTRICT 853 Pryor, Wyandotte, Vinita, Okla., and Siloam Springs, Ark., quadrangles, scale 1 : 125,000.) Existing project. During fiscal year 1941 the Grand River Dam Authority, an agency of the State of Oklahoma, under a license dated July 26, 1939, issued by the Federal Power Commission, com- pleted the construction of a reservoir for flood control and hydro- electric power at the Pensacola site in the Arkansas River Basin. The dam is of the concrete, multiple arch type, 6,565 feet long and 147 feet above the streambed. The existing dam and reservoir provides 1,653,000 acre-feet of storage to top of power pool and 245,000 acre-feet of flood-control storage. The flood-control stor- age lies between elevations 745 and 750. However, under the terms of the Federal Power Commission license, the dam and appurtenant structures were constructed to a height which would allow storage of flood waters to elevation 755 (Pensacola datum) when necessary lands or rights-of-way were acquired by the Federal Government. The Flood Control Act approved August 18, 1941, modified the general comprehensive plan for flood control and other purposes for the Arkansas River Basin to include the Pensacola, Markham Ferry, and Fort Gibson Reservoirs in the Grand (Neosho) River Basin in Oklahoma and Missouri, in accordance with recommenda- tions of the Chief of Engineers in House Document 107, 76th Con- gress, 1st session. The improvements recommended in that document included a reservoir for flood control at the Pensacola site which provided for 960,000 acre-feet of flood-control storage. The existing project which controls 10,298 square miles now provides for making available 278,000 acre-feet of flood-control storage between elevations 750 and 755 in addition to the storage provided in the project as constructed by the Great River Dam Authority. Flowage easements for certain portions of the neces- sary lands have been acquired by the Federal Government through the Southwestern Power Administration, Department of the In- terior, and the Federal Works Agency. The estimated cost (July 1957) for acquisition of additional flowage easements necessary for operation of the reservoir to elevation 755 is $1,760,000. The average annual maintenance cost during the past 5 years was $4,898. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. Flood control storage in the project was operated by the Grand River Dam Authority (an agency of the State of Oklahoma) under the direction of the Corps of Engineers. The Grand River Dam Authority was reimbursed for their expense in connection with maintaining and operating local protection works at Wyandotte, Okla. There were six noteworthy rises on the Grand (Neosho) River during the fiscal year. The pool elevation at the beginning of the fiscal year was 735.06 feet above mean sea level, corresponding to 1,259,000 acre-feet of total storage; and was 749.18 feet above mean sea level at the end of the fiscal year, corresponding to 1,875,000 acre-feet. The maximum pool elevation during the fiscal 854 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 year was 755.15 feet, corresponding to 2,206,000 acre-feet of total storage.

WISTER RESERVOIR, ARKANSAS RIVER BASIN, OKLA. Location. The Wister Dam is located on the Poteau River about 61 miles above its confluence with the Arkansas River and about 2 miles south of Wister, Le Flore County, Okla. (See U. S. Geological Survey map for Winding Stair, Okla., quadrangle, scale 1: 125,000.) Existing project. The plan of improvement consists of an earthfill dam about 5,700 feet long and rising 99 feet above the riverbed, with a reservoir storage of 400,000 acre-feet for flood control and 30,000 acre-feet for sedimentation reserve, recreation, and preservation of wildlife, a total of 430,000 acre-feet. An un- controlled concrete spillway located in a ridge in the right abut- ment provides for passage of floodflows into the valley below the dam. The outlet works consist of two 15.8 by 14-foot elliptical gated conduits near the present channel. A dike about 2,400 feet long and 40 feet in maximum height is provided in the right abut- ment. The reservoir, which controls 993 square miles, is operated as a unit of the coordinated reservoir system for flood control in the Arkansas River Basin. The costs (July 1955) were $7,587,700 for construction and $2,840,300 for lands and damages, a total of $10,428,000. The average annual maintenance cost during the past five years was $73,379. The existing project was authorized by the Flood Control Act approved June 28, 1938. (See Flood Control Committee Doc. 1, 75th Cong., 1st sess., which contains the latest published maps.) Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. The project was operated and maintained in a serviceable condition throughout the fiscal year, by hired labor. There were 15 noteworthy rises on the Poteau River during the fiscal year. The pool elevation at the beginning of the fiscal year was 471.60 feet above mean sea level, corresponding to 30,000 acre- feet of total storage; and was 502.75 feet above mean sea level at 862 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the end of the fiscal year corresponding to 435,000 acre-feet. The maximum pool elevation during the fiscal year was 505.73 feet corresponding to 507,000 acre-feet of total storage.

The cost for maintenance during the fiscal year was $58,982. Condition at end of fiscal year. The project is complete and is in operation. Construction of the embankment, spillway, and out- let works was started April 10, 1946; embankment closure opera- tions were started June 18, 1948, and completed in May 1949. However, initial storage operations were not begun until October 1949, inasmuch as the land acquisition, and relocation programs were not far enough advanced to permit storage prior to that date. Dedication ceremonies were held June 16, 1951. No additional new work construction is presently scheduled for this project. The total costs accrued to the end of the fiscal year were $10,428,000 for new work and $635,396 for maintenance.

Location The Denison Dam is located on Red River, 726 miles above the mouth of the river and 5 miles northwest of Denison, Tex. (See U. S. Geological Surveys maps for Denison, Tex., and Tishomingo, Okla., quadrangles scale 1 : 125,000.) Existing project. The plan of improvement consists of a rolled earthfill dam 15,200 feet long, rising 165 feet above the streambed with the reservoir providing a total storage capacity of 5,530,000 acre-feet, of which 2,694,000 are for flood control with 21,300 acre- feet of this amount being used jointly for flood control, power, and water supply, 1,730,000 are for power drawdown and the re- mainder, 1,106,000 acre-feet, is inactive storage for power head. The outlet works, consisting of a gate-control house and 8 conduits, each 20 feet in diameter, and the powerhouse, are located on the right abutment. A chute-type spillway 2,000 feet wide located in a saddle on the right bank will discharge floodflows through a creek to a point 1 mile below the dam. The plan of improvement also provides for the diversion of the Washita River and the construc- tion of levees to protect the Cumberland oil field from inundation, which levees have a length of 23,480 feet. A dike is provided across a saddle near Platter, Okla., on the left bank of Washita River, which has a length of 5,870 feet. The project, which con- trols 39,719 square miles, provides for flood protection to lands in Texas, Oklahoma, Arkansas, and Louisiana, the generation of power, improvement of navigation, regulation of the flow of the FLOOD CONTROL-TULSA, OKLA., DISTRICT 865 Red River, and for other beneficial uses. The hydroelectric de- velopment consists of 2 units having an installed capacity of 70,000 kw. The ultimate installation planned is for 5 units with a total of 175,000 kw.

The existing project was authorized by the Flood Control Act approved June 28, 1938, and amended by section 4, Public Law 868, 76th Congress, 3d session, approved October 17, 1940. (See H. Doc. 541, 75th Cong., 3d sess., which contains the latest published maps.) The Congressional act, Public Law 454, 78th Congress, chapter 456, 2d session, approved September 30, 1944, provided that from and after the enactment of that act the lake formed by the im- pounding of waters of the Red River by Denison Dam, shall be known and designated on the public records as Lake Texoma. The Congressional act, Public Law 273, 83d Congress, chapter 487, 1st session, approved August 14, 1953, further modified the project by authorizing the making of a contract with the city of Denison, Texas, for storage for a regulated water supply. The Congressional Act, Public Law 164, 84th Congress, chapter 371, 1st session, approved July 15, 1955, further modified the project to provide for a highway bridge across Lake Texoma at or near the Willis Ferry site. Local cooperation. Section 2 of the Flood Control Act, approved June 28, 1938, applies. In accordance with authority in Public Law 273, 83d Congress, 2d session, a water conservation contract has been negotiated with the city of Denison, effective October 5, 1953, wherein 21,300 acre- feet of storage are made available to that city at an annual cost of $13,800. The States of Texas and Oklahoma are each required to con- tribute the sum of $606,000 toward the cost of constructing the highway bridge across Lake Texoma at or near the Willis Ferry site. Operations and results during the fiscal year. All completed structures were operated and maintained in a serviceable condition throughout the fiscal year. Engineering studies for construction of highway bridge at Willis Ferry site were coordinated with the 866 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Oklahoma Department of Highways and contract plans and speci- fications were substantially completed. Construction of additional recreation facilities was started August 24, 1956 and continued throughout the fiscal year at a cost of $220,100 of which $9,800 was by contract and $210,300 was by hired labor. In addition, revet- ment protection to bridge foundations of the St. Louis-San Fran- cisco Railroad were started on November 19, 1956 and continued to 41 percent completion by contract. A total of 146,436,800 kilowatt-hours of electrical energy was delivered during the fiscal year to the Southwestern Power Administration for marketing. There were six noteworthy rises on Red River during the fiscal year. The pool elevation at the beginning of the fiscal year was 606.00 feet above mean sea level, corresponding to 1,969,000 acre- feet of total storage; and was 624.34 feet above mean sea level at the end of the fiscal year, corresponding to 3,560,000 acre-feet. The maximum pool elevation during the fiscal year was 643.15 feet, corresponding to 5,987,000 acre-feet of total storage.

RED RIVER BELOW DENISON DAM, TULSA DISTRICT Location. The work covered by this project is located on the Red River and its tributaries below Denison Dam, in Oklahoma, Arkansas, Texas, and Louisiana. Existing project. The Flood Control Act approved July 24, 1946, approved the general plan for flood control on Red River below Denison Dam, which provides for the construction of six flood-control reservoirs in combination with existing or authorized Federal and non-Federal levee improvements, modified as required, and channel stabilization at locations where levee setbacks are im- possible or uneconomical. Of the 6 reservoirs only 3 would be in the Tulsa District, with the other 3 located in the New Orleans District. This act further authorized the incorporation of the several separate existing projects for flood control along the Red River below Denison, above the jurisdiction of the Mississippi River Commission, into this project. The existing flood-control project for Red River below Denison Dam was further modified by the Flood Control Act approved August 3, 1955. The total estimated cost to the United States in the Tulsa Dis- trict (July 1957) is $99,252,105 for construction and lands and damages. The project was authorized substantially in accordance with House Document 602, 79th Congress, 2d session, and modified in accordance with House Document 488, 83d Congress, 2d session, which contains the latest published maps.

KANSAS CITYS ON MISSOURI AND KANSAS RIVERS, MO. AND KANS. Location. Kansas Citys on Missouri and Kansas Rivers in Missouri and Kansas. The municipal and industrial areas which require flood protection extend from the mouth of the Kansas River about 61/ miles up and 91/2 miles down the Missouri River and 91/2 miles up the Kansas River. Existing project. The general plan of improvement contem- plates protection works consisting principally of levees and flood- walls, for 13 separate project units, which are designated as follows : Argentine; Armourdale; Central Industrial; Fairfax- Jersey Creek; North Kansas City; East Bottoms; channel im- provement, Kansas River; bridge and approach alterations, Kan- sas River; channel improvement Missouri River; floodway im- provement, Missouri River; Birmingham; Blue Valley Industrial; and Liberty Bend cutoff. The existing project was authorized by the following: Acts Work authorized Documents June 22, 1936 Levees and flood walls for the protection of the Kan- H.

July 24, 1946 Authorized the Chief of Engineers to include neces- sary railroad bridge and approach alterations as a Federal responsibility. Sept. 3, 1954 Authorized accomplishment of alternate plan of improvement proposed by local interests for the Armourdale Unit (downstream section). Recommended modification of project. None. The estimated cost (1957) is $49,352,700, of which $44,300,000 is the Federal cost, $619,800 is for work accomplished with funds contributed FLOOD CONTROL-KANSAS CITY, MO., DISTRICT 883 by local interests, and $4,432,900 is for lands, damages, and relocations to be borne by local interests. This project will be operated as part of the comprehensive plan for the Missouri River Basin and it is contemplated that, with reservoir control, substantially complete flood protection will be provided for the Kansas Citys. The units involve construction approximately as follows: Argentine unit: The original levees and floodwalls built by private interests were of sufficient height to protect the district from the design flood, but to correct inadequate design and im- proper materials used in constructing the levees it was originally planned to strengthen the levees, install necessary facilities for control of underseepage, and construct a pumping unit. Since the inadequacies of the original construction by private interests were corrected through proper design and selection of materials in the emergency restoration necessitated by the flood of 1951, the levee work formerly contemplated under this unit no longer will be required. Armourdale unit: The earth levee along the left bank of the Kansas River from mile 6.7 to mile 2.91 is of sufficient height to provide protection from the design flood. The project provides for raising the existing levee from mile 2.9 to 2.8;1 constructing a new levee riverward of the existing floodwall from mile 2.8 to 1.7,1 replace existing floodwall with a new floodwall from mile 1.7 to 1;1 construct a new levee from mile 1 to 0.7;1 and raising existing streets and railroad tracks above the design flood eleva- tion between mile 0.7 and 0.25 ;2 with necessary alterations to the James Street Bridge and the Intercity Viaduct, and effecting a permanent raise of the Missouri Pacific Railroad bridge No. 1 in lieu of proposed temporary lifting facilities (bridge raise shown under Bridge and Approach Alterations, Kansas River, Unit). Central Industrial unit: Beginning at the south end of the Armour-Swift-Burlington Bridge over the Missouri River, mile 376.92 the protection for the district extends upstream along the right bank of the Missouri River to the mouth of the Kansas River, mile 378.8,2 a distance of 1.9 miles, and thence upstream along the right bank of the Kansas River to mile 3.4,1 in the vicinity of the Seventh Street Bridge a total distance of 5.3 miles. The improvements consist of concrete floodwalls and earth levees to protect the portion of the unit lying in the State of Missouri, and raising existing structures and new concrete floodwalls and earth levees to protect the portion of this unit located in the State of Kansas. Fairfax-Jersey Creek unit: About 30,900 feet of earth levee, 1,981 feet of concrete floodwalls, and 32,100 feet of bank-protec- tion works, extending along the right bank of the Missouri River from a point immediately above the Kansas City, Kansas, water and light plant (mile 385.3)2 downstream to the mouth of the Kansas River, thence along the left bank of the Kansas River to 1Above mouth of Kansas River. 2 Above mouth of Missouri River. 884 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the vicinity of the intercity viaduct (mile 0.3) ;1 pumping plants; and appurtenant works. Subsequent to the construction of the above work, the elevation of the design flood was raised due to a decrease in the width of the floodway, necessitating the raising of the Fairfax-Jersey Creek flood-protection works and the con- struction of 2,593 feet of concrete floodwall along the left bank of the Kansas River. North Kansas City unit: Beginning at a point northwest of the Kansas City, Mo., municipal waterworks, the protection for the unit extends downstream along the left bank of the Missouri River for a distance of about 6.55 miles and opposite approxi- mately Missouri River mile 375; thence north along the right bank of Rock Creek to the Wabash Railroad right-of-way, a distance of about 0.8 mile; thence northwesterly along a drain- age ditch to high ground northeast of the Kansas City, Mo., municipal waterworks, a distance of about 1.6 miles. The im- provements consist of raising and realinement of existing levees and a railroad embankment and new earth levees and concrete floodwalls to protect the city of North Kansas City, Mo., and the municipal airport and waterworks for the city of Kansas City, Mo. The total length of the system is 9 miles. East Bottoms unit: Beginning at the south end of the Armour- Swift-Burlington Bridge over the Missouri River, mile 376.9,2 the protection for the district extends downstream along the right bank of the Missouri River to the mouth of the Big Blue River, thence southwesterly along the left bank of Big Blue River to high ground. The improvements consist of levees and a floodwall and appurtenances. The plan also contemplates necessary rectification of the Big Blue River Channel near the mouth of this stream. Channel improvement, Kansas River unit: Bank-stabilization works along the right bank of the Kansas River from the Seventh Street Bridge to the Kansas City Terminal Railway bridge (mile 3.50 to mile 2.491 ) ; excavation of a foreshore bar along the right bank of the Kansas River, extending from the Kansas City Southern Railroad bridge (mile 0.84)1 to the mouth; and re- moval of major obstructions from the bed of the main channel of the Kansas River between the Argentine Bridge (mile 5.13)1 and the mouth. Bridge and approach alterations, Kansas River unit: In order to permit the free passage of drift during flood periods, it is con- templated that all bridges across the Kansas River between mile 5.13 and the mouth which do not now provide adequate floodway will be raised above the design flood profile. This would involve the permanent raising of 4 highway and 4 railroad bridges, and provision of facilities for the temporary raising during flood periods of 2 other railroad bridges. Channel improvement, Missouri River unit: The work under this unit consisted of dredging of a foreshore bar along the left bank of the Missouri River in the vicinity of mile 377.5 and of dredging the left bank where it extends riverward of the adopted 1Above mouth of Kansas River. 2Above mouth of Missouri River. FLOOD CONTROL--KANSAS CITY, MO., DISTRICT 885 channel alinement in the vicinity of mile 374.2 In addition, the abandoned overbank area between the North Kansas City levee and the present channel to approximately low water elevation was excavated. The left-bank approach fills to the Armour-Swift- Burlington and Hannibal Bridges were replaced by approach spans. This was necessitated by the widening of the Kansas City reach by setting back the North Kansas City levee and dredging the abandoned overbank area. Floodway improvement, Missouri River unit: The work con- templated under this unit consists of removing brush and timber from the area riverward of the existing Birmingham drainage mile 3702 and mile 3632 and of removing brush from the area district levee along the left bank of the Missouri River between riverward of the pronosed East Bottoms levee along the right bank between mile 373.52 and 367.8.2 Birmingham unit: In order to provide protection to the Birm- ingham district. various sections of the Birmingham levee, be- tween mile 371.6 and mile 361.5,2 were raised by the addition of rolled fill. Blue Valley industrial unit: The work contemplated under this unit consists of the construction of levees and floodwalls at ap- proximately present Big Blue River mile 5.4 to provide flood protection for a section of the Big Blue River Valley. However, this work has been assigned to inactive status based on official notification from local interests that the proposed improvements are no longer desired. Liberty Bend Cutoff: The work under this unit consisted of the construction of a main cutoff channel beginning at mile 363.7 and extending downstream to a mile 358.5 ;2 a second cutoff chan- nel from mile 358.5 to mile 357:2 and a new highway bridge where the main cutoff channel intersects United States Highway No. 71 (by-pass), which at present crosses the Missouri River north of the pronosed cutoff at mile 361.2 Local cooperation. The necessary assurances of cooperation by local interests with respect to the Flood Control Act of June 22. 1936. were approved by the Secrtary of the Army as follows: A rgentine ; Armourdale: bridge and approach alterations, Kan- sas River: Central Industrial (Kansas section) : channel improve- ment.

Other miscellaneous costs, all charged to maintenance, were stream gaging and special studies for working data at a cost of $40,477, surveys and mapping at a cost of $67,199, navigation studies at a cost of $200, channel reconnaissance at a cost of $51,300, channel marking at a cost of $76,242, and all other costs of $196,369. The total cost during the fiscal year of all maintenance work was $2,995,933. Condition at end of fiscal year. Construction was initiated on the project in fiscal year 1928 and the scheduled completion dates are Sioux City to Omaha fiscal year 1967 and Omaha to Kansas City fiscal year 1964. The work on the entire project Kansas City, Mo. to Sioux City, Iowa, was approximately 63 percent complete at the end of the fiscal year, based on the present approved estimate of cost. Kansas City to Omaha: The work on this section of the project was approximately 82 percent complete at the end of the fiscal year. The work remaining to be done to complete this section of the project consists principally of the construction of additional bank stabilization structures and the strengthening of existing pile structures to improve their effectiveness and to prevent their deterioration prior to final stabilization of the banks. A reliable channel suitable for navigation is available through this section. The practical draft at ordinary stages of the river is 61/ feet, with additional depths available during high stages. Commercial navigation was inaugurated on this section in May 1939 but was interrupted due to the war from 1942 until October 1946, at which time common carrier transportation service was inaugurated. Omaha to Sioux City: The work between Omaha, Nebr. and Sioux City, Iowa was approximately 43 percent complete at the end of the fiscal year. Considerable progress has been made in stabilizing the river channel and alleviating the critical erosion problems from Sioux City to Dakota City, a 16-mile stretch up- stream from Decatur, the reach from Mondamin to Blair, and from Fort Calhoun to Omaha since resumption of work in 1955. Where work has not been initiated much of the channel is wild and erosion is active. In those reaches the crossings are wide and very crooked, resulting in extensive shoaling. The channel is not used commercially as the controlling depth is limited to 4 feet. Under the existing project for systematic work on the 9-foot channel, the work accomplished includes 1,655,258 linear feet of revetment for permanently fixing the banks, 2,636,309 linear feet of pile and rock dikes, 143,884 linear feet of abatis, 2,287 linear feet of jetties, recrowning 700 linear feet of an existing levee, 19,218 linear feet of retards for stabilization of channel widths, construction of five impermeable structures to close off auxiliary channels, construction of 48,237 linear feet of asphalt revetment, effecting three channel cutoffs, and removal of 104,029,592 cubic yards of material dredged from the channel to obtain project depth and width.

A project for flood protection on Little Sioux River, Iowa, authorized by Public Law 341, 80th Congress, 1st session, ap- proved August 4, 1947, in accordance with the recommendations in House Document 275, 80th Congress, 1st session, was modified and supplemented substantially in accordance with recommenda- tions of the Chief of Engineers in Senate Document 127, 83d Congress, 2d session, and was authorized by the Flood Control Act approved September 3, 1954. The estimated cost of the improvement is $18,890,000 (July 1957) of which $15,500,000 is Federal cost for construction and $3,390,000 is local costs for lands, damages, bridge construction, bridge alterations, and relocations of roads, buildings, power and telephone lines and pipe lines. Local cooperation. Local interests are required to furnish, free of cost to the United States, all lands, easements and rights-of- way; to perform without cost to the United States all necessary highway, highway bridge and utility alterations except raising of highway bridges which would be done at Federal expense; main- tain the project upon completion; and hold and save the United States free from claims for damages resulting from the improve- ments. The project is sponsored by the Nagel drainage district and the Little Sioux intercounty drainage district. The Nagel drainage district covers the area along the Little Sioux River from the proposed diversion ditch below Kenebec, Iowa, upstream to near Smithland, Iowa. The Little Sioux intercounty drainage district was organized by the county boards of Monona and Harrison Counties and includes all the area covered by the project except those covered by the Nagel drainage district. Formal assurances of local cooperation from the Little Sioux intercounty drainage district were approved by the District Engineer on 28 February 1956. Formal assurances from the Nagel drainage district will be requested when final channel and levee alignments are known in order to eliminate the necessity for filing an amended plan with the State of Iowa. However, there is a formal agree- ment between the two drainage districts which provides that the Nagel drainage district will provide the local cooperation for their portion of the project when requested. Approximately 25 percent of the total rights-of-way have been acquired by the Little Sioux intercounty drainage district. Rights-of-way for the remainder of the work will be requested as final plans are 926 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 completed.

LOWER HEART RIVER, N. DAK. Location. The project is located in the vicinity of Mandan, N. Dak. on both banks of the Heart River in the 14-mile reach extending upstream from the mouth of the river. Existing project. The plan of improvement provides for raising the present Mandan levees, highway and railroad bridges; provides a closure levee extending from United States Highway No. 10 to high ground upstream (west) from Mandan; and provides for channel improvement and levee construction down- stream (east) of Mandan. Improvement will increase protection to the city of Mandan and the State Training School and will provide protection for two additional areas which are rural in development. The project was authorized in the Flood Control Act approved September 3, 1954. (Public Law 780, 83d Cong., 2d sess.) The estimated cost of improvement (July 1957) is $2,052,400, of which $1,750,000 is Federal cost of construction and $302,400 is local cost. Local cooperation.

BILLINGS, YELLOWSTONE RIVER, MONT. Location. The work covered by this project is located at Bil- lings and vicinity on Yellowstone River, Mont., 346 river-miles upstream from its confluence with the Missouri River. Existing project. The overall plan of improvement for the flood protection of Billings and contiguous areas consists of a system of ditches, channels, and levees by means of which flood- waters approaching the city from the west, east, or south may be diverted away from the area subject to flooding. The proposed plan is divided into three separate units. The western unit of the plan consists of an interception ditch which will divert runoff from west of Billings into the Yellowstone River. Reinforced concrete spillways will divert storm waters from four irrigation canals which cross the alinement of the proposed interception ditch, and drainage from other areas will enter the ditch through control spillways. Necessary appurtenances to the interception ditch are a reinforced concrete stilling basin, earth levees, a reinforced con- crete chute and stilling basin. A railroad bridge and several ad- ditional highway bridges over the proposed interception ditch and other similar improvements will be necessary for completion of this unit. The eastern unit of the plan is designed to protect the fairgrounds and adjacent areas east of Billings from floods on Alkali Creek. The proposed plan consists of two sections of levee along the right bank of the existing channel; a cutoff channel 510 feet long excavated through the rock escarpment including a still- ing basin; and an enlargement of the existing channel from the stilling basin to the Yellowstone River. A railroad bridge will be necessary for this unit. The southern unit of the overall plan is designed to protect the areas south and east of Billings from floods on the Yellowstone River. This unit consists of a levee along the left bank of the river, and necessary appurtenant interior drainage 950 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 structures. An existing levee will be incorporated into the pro- posed works. The project was authorized by the Flood Control Act approved May 17, 1950 (H. Doc. 216, 81st Cong., 1st sess.). The estimated Federal cost (July 1957) is $4,290,000; the esti- mated local cost (July 1957) is $327,000 for relocations, lands, and damages. Local cooperation. In addition to the usual requirements for local cooperation, local interests are required to remove or relocate all structures at or near the alinement of the proposed work, pro- vide all bridges and similar improvements, and construct or re- locate roads. Assurances of local cooperation have not been requested from local interests. In September 1956, the city of Billings advised that they are delaying any future plans for de- velopment of flood control for the western unit due to inability to furnish necessary assurances of local cooperation and lack of local support for construction of that unit. In November 1956, Yellow- stone County officials requested that consideration be given toward early construction of the eastern unit of the project. These offi- cials have indicated that the County is financially able to provide necessary local cooperation and are now conducting a survey of affected property owners before forming a special improvement district. Assurances of local cooperation will be requested upon firm assurance from local interests that local cooperation for the eastern unit can be furnished. Operations and results during the fiscal year. Work was con- tinued on field surveys, investigations and detailed plans. The total cost during the fiscal year was $13,066. Condition at end of fiscal year. The general design memo- randum is complete and preparation of plans and specifications is approximately 5 percent complete. No construction has been initiated. Total cost to June 30, 1957 was $47,270, all regular new work funds.

SHERIDAN, YELLOWSTONE RIVER, WYO. Location. The work covered by this project is located at Sheri- dan and vicinity on both sides of Goose Creek and Little Goose Creek approximately 11.6 miles above the junction of Goose Creek with the Tongue River, FLOOD CONTROL--GARRISON, N. DAK., DISTRICT 951 Existing project. The overall plan of improvement for flood protection at Sheridan consists of a system of levees and flood- walls in combination with alterations of the channels of Goose Creek and Little Goose Creek. The area subject to flooding from Little Goose Creek will be protected by approximately 12,800 feet of levee, 2,750 feet of vertical concrete floodwall and approximately 1,500 feet of new channel. The proposed works for protection of areas along Big Goose Creek include approximately 1,700 feet of new channel, 28,600 feet of levee, 330 feet of concrete floodwall, and 9,500 feet of improved channel. Riprap will be placed on earth slopes for a distance of 50 feet above and below all bridges, and the outside banks on all curves where erosion is likely to occur. Grouted riprap will be placed in drop sections of both streams. The project was authorized by the Flood Control Act approved May 17, 1950 (H. Doc. 216, 81st Cong., 1st sess.). The estimated Federal cost (July 1957) is $2,590,000; the estimated local cost (July 1957) is $46,000 for relocations, lands, and damages. Local cooperation. In addition to the usual requirements for local cooperation, local interests are required to remove or relocate all structures at or near the alinement of the proposed work, pro- vide all bridges and similar improvements, and construct or re- locate roads. It is estimated that assurances of local cooperation will be requested from local interests early in fiscal year 1958. Local interests have indicated their willingness and ability to comply with all requirements of local cooperation. Operations and results during fiscal year. Preparation of the design memoradum was initiated. The total cost during the fiscal year was $61,651, all regular new work funds. Condition at end of fiscal year.

CONSTRUCTION OF LOCKS AND DAMS ON THE OHIO RIVER Location. The Ohio River is formed by the junction of the Allegheny and Monongahela Rivers at Pittsburgh, Pa., and flows in a general southwesterly direction for a distance of 981 miles to join the Mississippi River near Cairo, Ill. For description of the river see page 1227, Annual Report for 1932. Previous projects. The first lock and dam on the Ohio River was provided for by River and Harbor Act of March 3, 1879. The construction of dams was provided for by River and Harbor Acts, as follows: Dam 6, September 19, 1890; dams 2, 3, 4, and 5, June 3, 1896; 13 and 18, March 3, 1899; 8, 11, 19, and 37, June 13, 1902; 26, March 2, 1907. For further details see page 1907 of Annual Report for 1915. For expenditures on the previous 6-foot canal- ization see paragraph "Condition at end of fiscal year" of this report. Existing project. This provides for the improvement of the entire river by the construction of locks and dams to provide a channel depth of 9 feet and for the widening of the Louisville and Portland Canal at Louisville, Ky. The project provides for a lock with usable dimensions of 110 by 600 feet at each of the dams and, in addition, an auxiliary lock 56 by 360 feet is available at Ems- worth, Dashields, Montgomery, and dam 41, with an auxiliary lock at Gallipolis being 110 by 360 feet. Dashields is a fixed dam, while Emsworth, Montgomery, and Gallipolis are fixed dams with movable crests. The remainder of the 46 dams are of the movable type, with navigable pass varying in width from 600 to 1,248 feet. In addition to the navigable pass, the movable type 955 956 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 dams are also provided with one or more regulating weirs. At dam 41 a canal (Louisville and Portland) extends along the left bank for a distance of 2 miles, with locks at the lower end. Modi- fications to the existing project provide for fixed dams with mov- able crests with two locks (110 by 1200 feet and 110 by 600 feet) at New Cumberland, Greenup, New Richmond, and Markland, and reconstruction to provide a 110- by 1200-foot lock and other improvements at locks and dam 41. Operation and care of the locks and dams were included in the project July 1, 1935, under the provisions of the Permanent Appropriations Repeal Act approved June 26, 1934. The estimate of cost of new work (existing project) (1957), ex- clusive of Gallipolis locks and dam reported under the Kanawha River project, is $633,135,000. The foregoing estimate does not include expenditures on previous projects. The following items previously included in this project are con- sidered to be inactive and are excluded from the foregoing cost estimate: Raising crest of dam 14; construction of beartraps at dam 21; construction of additional beartraps at dams 18, 22, 23. 27, 30, 39, and 43 and construction of guard wall and guide wall extensions at locks and dams 35, 41, 44, 45, 46, 48, 49, 50, 51, and 52. The cost of these items was last revised in 1954 and was estimated to be $11,064,700. The average annual operation and maintenance cost during the past 5 years was $6,893,000. The existing project was authorized by the following: Acts Work authorized Documents Mar. 3, 1909 Secretary of War authorized to approve reconstruc- tion with such modifications in plan and location of existing works as may be necessary to provide adequate facilities for existing navigation.

The navigation system of 46 locks and dams is in operation and 9-foot navigation throughout the entire length of the river is generally available at all times. At certain unstable bars the project depth is maintained by dredging, supplemented by contraction works. (See project "Open channel work Ohio River", page 962.) Table A under "Existing project" shows cost and year of completion of locks and dams now in opera- tion. The existing project does not provide adequate facilities for present day navigation due to obsolescence of the structures. Since repair and modernization of these facilities would be ex- tremely costly, replacement and reconstruction is being undertaken as rapidly as funds can be made available for the purpose. Con- struction of the following locks and dams was initiated during the fiscal year 1955: New Cumberland locks and dam (Strattonville, Ohio) to replace locks and dams 7, 8, and 9; and Greenup locks and 962 REPORT OF THE CHIEF OF ENGINEERS, U.

The portion of the river included in the project extends from the head of the river at Pittsburgh, Pa., to the mouth of the Cache River (Mound City, Ill.), a distance of 974.7 miles. Open channel improvement from the mouth of the Cache River to the mouth of the Ohio River is under the jurisdiction of the Mississippi River Commission. Existing project. Prior to the completion of the canalization project, no project depth had been fixed by Congress under the project for open channel work, but in order to properly aid packet and barge navigation it was found necessary to secure a low water channel having a minimum depth of from 4 to 6 feet, and a width, depending upon the difficulty of running the channel, of from 400 to 600 feet; also to permit the movement of large coal tows, which movement occurred at stages of water exceeding 10 feet, it was found necessary to remove the points of projecting bars which formed at various locations along the river. The accomplishment of this purpose involved the concentration of current by closing back channels at islands with low dams, the contraction and straightening of wide, open channels by low dikes, dredging of bars and shoals, and the removal of snags and wrecks. Since the completion of the canalization project, the work under the project for open channel work provides mainly for widening, deepening, and maintenance of the channel in the pools of the dam, and in the open river section of the river below lock and dam 53 so as to provide and maintain the full project depth of 9 feet contemplated by the canalization project. Channel widths generally are in excess of 500 feet, except at critcal bars where there is periodic recurrent shoaling. Channels 300 feet in width are maintained at critical bars by periodic dredging. Such channels may become constricted to a width of 250 feet before dredging can be accomplished. These channel widths are the minimum that will facilitate the movement of the present day barge tows. The accomplishment of this work not only involves dredging of bars and shoals, but the construction and maintenance of back channel dams, dikes, and bank revetments for stabilizing the channel, and the removal of snags and wrecks. Incidental to the direct improvement of the Ohio River is the construction and maintenance of ice piers as required for the protection of river craft. The stage of extreme high water on the Ohio River varies from 46 feet at Pittsburgh, Pa., to 80 feet at Cincinnati, Ohio, with 57.2 feet at Louisville, Ky. (head of falls), 53.8 feet at Evansville, Ind., and 59.5 feet at Cairo, Ill. (mouth of river). The estimated cost of new work (1957) is $16,160,000, which is exclusive of the additional ice piers authorized by the River and Harbor Act of January 21, 1927, and the reforestation of sloughs on Kentucky Peninsula near Evansville, Ind., authorized by the River and Harbor Act of July 3, 1930. The following.items included in the project are considered to be inactive and are ex- cluded from the foregoing cost estimate: Ice piers authorized, by the River and Harbor Act of January 21, 1927; reforestation of 964 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 sloughs on Kentucky Peninsula near Evansville, Ind., authorized by the River and Harbor Act of July 3, 1930; dredging to widen the channel at certain points; and placing of revetment at various points. The cost of these items was last revised in 1954, and was estimated to be $6,565,000. The average annual maintenance cost during the past 5 years was $750,135. The existing project was authorized by the following: Acts Work authorized Documents Mar. 3, 1827 The project adopted by this act originally covered the entire length of the Ohio River from its mouth near Cairo to Pittsburgh, a distance of 981 miles. It pro- vided for the removal of all obstructions which tend to endanger steamboat navigation. Jan. 21, 1927 Construction of ice piers as a part of the project, with H.

Doc. 409, 69th Cong., 1st sess. near Evansville, Ind., and a 200-foot strip along the upstream bank and for bank protection at an estimated cost of $200,000. Operation of snag boats on the Ohio River below the Pennsyl- vania State line was included in the project July 1, 1935, under the provisions of the Permanent Appropriations Repeal Act approved June 26, 1934. Local cooperation. The River and Harbor Act approved Janu- ary 21, 1927, authorizing the construction of ice piers for general open-channel work, imposes the condition that before work is begun on any ice pier, local interests convey to the United States free of cost such riparian rights as may be deemed necessary in connection with the improvement at the locality (H. Doc. 187, 67th Cong., 2d sess.). Existing ice piers are adequate for present purposes and local cooperation is not needed since no additional construction is under consideration. The River and Harbor Act approved July 3, 1930, authorizing the reforestation of the sloughs on Kentucky Peninsula near Evansville, Ind., and a 200-foot strip along the upstream bank and for bank protection, provides that no expense shall be incurred by the United States for acquiring of any lands required for the pur- pose of this improvement (H. Doc. 409, 69th Cong., 1st sess.). However, since no serious overbank erosion has occurred since the bank revetment in 1933-34, reforestation is not considered justifiable at this time and no local cooperation is required. Terminal facilities. See page 960. Operations and results during fiscal year. Dredging, where re- quired to provide an adequate and dependable channel of project depth at minimum pool conditions, was executed. The dike and revetments were maintained and the routine work of maintaining navigation aids, removing snags, making channel studies, and hydrographic surveys was performed as required. The specific work accomplished during the year was as follows: Operation and maintenance, general: The following dredging and other maintenance work was performed: OHIO RIVER 965 Operation and ordinary mainteance: Channel soundings; hydrographic surveys; stream gaging operations; channel inspections and aids to navigation; preparation of navigation charts; miscellaneous inspections and reports ----------------------------------- $188, 617 Rehabilitation: Dredging (contract and hired labor) : Cubic yards Cost Pittsburgh District: 3, 039 $11, 234 Huntington District:--------------- 196, 871 75, 449 Louisville District :---------------- 2, 683, 602 600, 797 687, 480 Snagging and clearing------------------------------------- 288 Total ---------------------------------------------- 876, 385 The total cost during the fiscal year on the entire river, all for operation and maintenance, general, was $876,385.

In addition to dredging, local stabilization of the channel has been effected at various points by construction of dikes and revetment. The work which remains to be done consists of dredging to widen the channel at certain points to the project depth. The total costs of the existing project to the end of the fical year were as follows: Public works Class of work Regular funds funds Total New work ------------------------------- $14,922,024 $1,040,236 $15,962,260 Operation and maintenance, general... 134,045,387 ---... -.-. 34,045,387 Total------------------------------- $48,967,411 $1,040,236 $50,007,647 1This amount includes $1,000 for removal of obstructions in Licking River under authority of Sec. 3 of the River and Harbor Act approved July 3, 1930.

This river is formed by the junction of Poor and Clover Forks in Harlan County, Ky., about 692.8 miles above its mouth, and flows west to Burnside, Ky., from whence it makes a loop southwestward into Tennessee, passes Nashville, and returns northwestward to Kentucky, emptying into the Ohio near Smith- land, Ky. (See U. S. Geological Survey base maps of Tennessee and Kentucky.) Previous projects. Below Nashville: The River and Harbor Act of July 3, 1832, made the first appropriation for this section of the river, but the River and Harbor Act of March 3, 1871, was the first to define a project for its improvement. The River and Harbor Act of September 19, 1890, adopted a special project for the im- provement of the mouth of the river. For further details see page 1901 of Annual Report for 1915, and page 1208 of Annual Report for 1938. Above Nashville: Adopted by River and Harbor Acts of August 14, 1876, March 3, 1881, and July 5, 1884. For further details see page 1898 of Annual Report for 1915, and page 1208 of Annual Report for 1938. Existing project. Below Nashville: Prior to adoption of the 9-foot navigable channel defined in succeeding paragraphs, the project for this section of the river provided for the construction of locks and dams A, B, C, D, E, and F, and dredging in the 43.6 miles from lock F to the mouth to secure 6-foot navigation at the extreme low water from the mouth to lock and dam 1, Nashville, 967 968 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Tenn. (188.4 miles above the mouth), the first lock constructed under the project for the section of the river above Nashville. The surmounting of dams A to F with movable crests was also provided. Dredging in the lower river was made unnecessary by the con- struction of lock and dam 52, Ohio River, which created a pool of more than 6-foot depth from lock F to the mouth. The cost of new work for completion of the 6-foot navigation project was $4,706,883, excluding amounts expended on previous projects.

(See H. Doc. 761, 79th Cong., 2d sess.) In addition to supplemental authority granted in Public Law 396, 82d Congress, 2d session, approved June 19, 1952, which provided RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 969 for the construction of hydroelectric power-generating facilities at Cheatham Dam, river mile 148.7, the River and Harbor Act of 1954 (Public Law 780, 83d Cong., 2d sess.) authorized further modi- fication of the project for navigation on the Cumberland River, Tenn. and Ky., to provide, in lieu of the previously authorized works at Kuttawa, mile 32.2, and Dover, mile 100.1, for the con- struction of a multiple-purpose improvement for navigation, flood control, and hydroelectric power consisting of a dam, lock, and powerplant in the vicinity of mile 30.6 on the lower Cumberland River and a canal for navigation and other purposes connecting the proposed reservoir with the reservoir formed by Kentucky Dam on the Tennessee River.

S. ARMY, 1957 be constructed on the lower Cumberland River, Ky., authorized by the River and Harbor Act of 1954, and the reservoir to be formed by the waters impounded by such dam, should thereafter be known and designated on the public records as Barkley Dam and Lake Barkley, respectively. Provision of the interconnecting canal, equipped with control gates and involving excavation of a channel through the narrow watershed divide at a point about 2.5 miles up- stream from the dam site, will make alternative routes available for navigation between either the Cumberland or Tennessee Rivers and the Ohio River, and will afford integrated operation of Barkley and Kentucky Reservoirs through the diversion of flows in the interests of flood control and power production. The estimated cost of the modified project for 9-foot navigation and multiple-purpose development is $204,200,000 (July 1957). The principal features of the works of improvement are sum- marized in the table on page 969, using tentative data for the Barkley project pending completion of definite design studies. Under flood conditions as regulated by upstream reservoirs, the extreme fluctuation in stage of the river below Nashville, Tenn., varies at different localities from about 16 to 48 feet. Ordinary fluctuations vary with power flows from as much as the allowable 3-foot drawdown below normal pool elevation 385 at Cheatham Dam to a range of about 5 feet above that level at Nashville, with variations up to 7 feet in the reach of the river below Cheatham Dam. The existing project for the section below Nashville was authorized by the following River and Harbor Acts: Acts Work authorized Documents July 13, 1892 Provision made for lock A_----------------------- Annual Report, 1890, p. 2151.

Above Nashville: The River and Harbor Acts of August 5, 1886, March 2, 1907, March 2, 1919, and June 5, 1920, provided for the construction of locks and dams 1 to 17 and 21 to secure 6-foot navigation at low water from Nashville (lock and dam 1, 188.4 miles above the mouth) to Waitsboro Shoals (a distance of 324.6 miles), and 4-foot navigation from Waitsboro Shoals to Burnside (3 miles); provision also being made for the periodic removal of snags and similar obstructions from Nashville (lock and dam 1) to Burnside (327.6 miles). The project as modified by the River and Harbor Act of July 3, 1930, further provided for RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 971 raising dam No. 1 by 3 feet (Rivers and Harbors Committee Doe. 26, 70th Cong., 2d sess.). Under the above authority, locks and dams 1 to 8, inclusive, and 21 were completed and placed in operation during the period 1888-1924. The raising of dam 1 by installation of crest wickets was completed in October 1931. Proposed locks and dams 16 and 17 were eliminated from the project upon authorization of Lake Cumberland (Wolf Creek Reservoir) (p. 990), the construction of which has also resulted in the permanent inundation of lock and dam 21. The principal features of locks and dams 1 to 8, inclusive, are given in the following tabulation; for comparable details on lock and dam 21 (abandoned) and the other structures contemplated under the project, see Annual Report for 1950: Lock 1 1 Lock 21 Lock 31 Lock 4 1 Nearest railroad sta- tion.

S. ARMY, 1957 above Nashville for navigation and power. The cost, including a lock at Old Hickory, is estimated as $125,100,000 (July 1957). Prosecution of the modified project for this section of the river will result in the elimination of locks and dams 2 to 8, inclusive, and precludes further consideration of the previously projected locks and dams 9-15, inclusive.

At Nashville, Tenn., there is a 5-story terminal building 300 feet long and 140 feet wide, built of rein- forced concrete having large and convenient loading platforms, electric elevator and gantry crane, with railroad connections, municipally owned and open for public use. There is an additional terminal, privately owned, with modern facilities and railroad connections, also available for public use. At Clarksville, Tenn., there is a privately owned warehouse with inclined tramway. Privately owned terminals for the transfer of petroleum prod- ucts have been constructed at Dover, Clarksville, and Nashville, Tenn. There are also privately owned terminals located near Smithland, Ky., used for the transfer of riprap rock; near Kut- tawa, Ky., for the transfer of asphalt; at Dycusburg, Ky., for the transfer of fluorspar; at Clarksville, Tenn., for the trans- fer of sand and gravel; and at Nashville, Tenn., for the transfer of sand and gravel, scrap metals, asphalt, and molasses. In addi- tion to the foregoing there are many unimproved private landings along the river. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. a. Below Nashville: Operations for completion of the Cheatham unit of the existing project as modified for 9-foot navigation and multiple-purpose development were continued. 974 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Under a continuing contract for construction of the powerhouse superstructure, the following quantities of major items of work were accomplished, in addition to various operating equipment installations: Common excavation, 250 cubic yards; concrete placed, 10,855 cubic yards; steel reinforcing, 1,502,900 pounds; and galvanized steel, 84,825 pounds. With continuation of activ- ities under outstanding supply contracts, Government-furnished items of power plant equipment were received on the project as follows: main power transformers; 175-ton powerhouse crane; 50-ton intake gantry crane; 15-ton draft-tube gantry crane; and miscellaneous accessory electrical equipment. Delivery was also made under a contract initiated and completed during the year for microwave-radio transmitting, receiving, multiplexing, and accessory equipment. Reservoir operations consisted of completion of work under a continuing contract for additional (Group 3) clearing, and under an agreement for adjustment of the Ashland City, Tenn., water plant to project conditions; rebrushing for malaria control pur- poses by hired labor; and activities under the real estate program. In the latter connection, three acres were acquired in fee; and with continued legal action, final judgments were entered on seven cases in condemnation. Two acres previously acquired in ease- ment merge with fee taking under the Old Hickory lock and dam project. jired labor operations also included procurement of permanent operating equipment, preparation and issuance of plans and speci- fications for power plant equipment contracted during the year, and several minor construction items pertaining to completion of lock, dam, and powerhouse features of the project. Construction of the Barkley project was initiated late in the fiscal year under a continuing contract for placement of the coffer- dam for the navigation lock, common excavation for the lock chamber and wall structures, construction of the left bank earth- dam section, and provision of an access road to the work area. Preparation of the general design memorandum and definite de- sign studies relating to various project features were accomplished by hired labor, as were preparation and issuance of plans and specifications for the initial phase of construction. In addition to acquisition of approximately 633 acres of the lands required for the dam site and work area, a one-acre tract in the reservoir area of Cadiz, Ky., was acquired for use as a real estate project office. The costs for new work were $5,615,956. Channel work by Government plant and hired labor consisted of removing 262 snags from the channel, and dredging 27,825 cubic yards of material at the following sites: 6,125 cubic yards at Kuttawa Bar; 10,915 cubic yards at Big Horse Ford; and 10,785 cubic yards at Tobaccoport Bar. The cost of channel maintenance was $47,357. b. Above Nashville. Construction under the modified project for this section of the river was continued under contracts for features of the Old Hickory unit. Under the continuing contract RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 975 for construction of the power plant, the work accomplished con- sisted principally of the following: concerete placed, 6,400 cubic yards; structural and reinforcing steel placed, 235,200 pounds; essential completion of powerhouse building proper; work incident to installation of turbines, governors, generators, cranes, and various operating systems; and construction of the permanent upper lock-gate sill. The initial power unit was completed and placed on the line, and installation of Unit No. 2 was essentially completed. Delivery of all Government-furnished items of powerhouse equipment under outstanding supply contracts was completed. Work was also completed under contracts or agreements for the following: necessary roadway relocations in Davidson and Trousdale Counties, Tenn.; adjustment of power lines and facilities of the Nashville, Tenn., Electric Power Board; relocation of the Hendersonville, Tenn., water plant; relocation of affected power lines of the Cumberland Electric Membership Corporation; modifi- cation of the Lebanon, Tenn., raw water plant; reservoir clearing, Group 3 (1,883 acres) ; and construction of repair and storage facilities at the project site. Operations under continuing con- tracts for channel dredging below the dam and demolition of locks and dams 2, 5, and 6 were essentially completed. A contract was entered into during the year for construction of a combination office and comfort station building, with supporting utilities, on which work was undertaken and well advanced. Operations under a contract awarded near the end of the year for demolition of lock and dam 7 were not commenced. In addition to preparation and issuance of plans and specifica- tions for work items contracted during the year, hired labor operations included preparation of such for bank protection meas- ures for the lower approach to the lock; bank emergency repairs; operational access road construction; procurement of permanent operating equipment items; miscellaneous work concerning demoli- tion of existing locks; and cleanup, minor construction, and instal- lations pertaining to completion of the dam and power features of the project. Dredging operations during the year by hired labor to provide project depth for navigation in the upper reach of the Old Hickory pool consisted of removing 109,766 cubic yards of material at the following sites: Saunders Island, 41,428 cubic yards; head of Goodall Island, 41,822 cubic yards; lower end of Goodall Island, 24,826 cubic yards; and Carters Island, 1,630 cubic yards. With continuation of legal action under the real estate program, final judgments were entered on 38 cases in con- demnation. Authority was granted during the year to acquire an additional 15 acres immediately below the dam which are affected by velocity and direction of flow of water discharged. This area includes 2 acres originally acquired as easement in the Cheatham pool. Preliminary work (engineering and design) in connection with the Carthage and Celina Dams was suspended throughout the year. The costs for new work were $4,322,614. No channel maintenance costs were incurred. 976 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 c. Operation and maintenance of structures: Locks B to F, inclusive, Cheatham, Old Hickory, and No. 2 were operated as required. Maintenance and improvement operations included relatively minor repair and alteration of lock operating machinery and installation of navigation distance markers at the Cheatham and Old Hickory projects; and installation of boat davits and floodlights, respectively, at those locks. The cost of operation and maintenance of structures was $721,654. The total costs during the fiscal year were $10,707,581, of which $9,938,570 was for new work, and $769,011 for operation and maintenance, general. Condition at end of fiscal year. a. Below Nashville: Locks and dams A to F, inclusive, under the 6-foot navigation project for this section of the river were constructed during the period 1895-1923. The dates on which the individual units were com- pleted and placed in operation are given in the tables under para- graph "Existing project." Full all-year project depth between the mouth and Nashville was obtained in December 1935, with completion of work for surmounting the dams with movable crests. Subject to replacement by new facilities under construc- tion, lock and dam A was closed to navigation on September 22, 1954, and the structures demolished. Under the authorized modification of the existing project for multiple-purpose development, including further improvement be- low Nashville for 9-foot navigation, new work as a whole was approximately 14 percent complete. Engineering and design were about 32 percent complete. Construction was commenced in April 1950 when operations were initiated under a continuing contract for construction of the Cheatham lock, access road, and operations building. The lock was placed in temporary operation on December 12, 1952, and completed for permanent operation on August 7, 1954. The dam was constructed during the period August 1952 to October 1954. A contract for the powerhouse substructure, iniated in October 1954, was completed in May 1956. Construction of the power- house superstructure was initiated in March 1956, and was ap- nroximately 55 percent complete at the end of the fiscal year. The statls of work under outstanding contracts for Government- furnished equipment was as follows: Turbines, 97 percent com- plete. %vernors, 96 percent; generators, 84 percent: accessory electrical equipment, 88 percent; and miscellaneous power plant eauipment, 77 percent. Provision of storage facilities for the spillwav bulkheads under the contract for completion of the powerhouse was 78 percent complete. Reservoir clearing (3 contracts), relocation of affected roads in the two counties involved, cemetery removals (73 graves), neces- sarv railroad relocation work, demolition of locks and dams, A, and 1, and required channel dredging have been completed. Ap- proximately 7,111 acres, or 99.8 percent of the lands required for nurnoses of the project, have been acquired: 5,717 acres in fee simnle. and 1,394 acres in easement. The Cheatham project as a whole was 89 percent complete. RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 977 Operations under the contract for the initial phase of con- struction on the Barkley project (cofferdam and excavation for the lock; left-bank embankment section; and access road) were in progress. Upon mobilization of forces and plant, the con- tractor commenced work on June 7, 1957. The reservoir lands acquired to date, 634 acres, represents 0.6 percent of the total project requirements. The total new work costs for this section to June 30, 1957, were $33,374,040, including $685,000 from public works funds. The total costs for channel maintenance were $971,918. b. Above Nashville: Prior to modification of the existing project for this section of the river in 1946, locks and dams 1 to 8, inclusive, and 21 had been completed; the initiation of work on lock and dam 1 in September 1888 marking the commencement of construction under the project. The dates on which the com- pleted structures 1 to 8 were placed in operation are given in the table under paragraph "Existing project." Lock and dam 21, completed in October 1911, has since been inundated by Lake Cumberland (described on page 990), which also eliminated pro- jected locks and dams 16 and 17. Operation of lock 21 was dis- continued on May 4, 1947; custodial services only being main- tained until May 31, 1949, at which time the structure was abandoned. Lock and dam 1, demolished in connection with con- struction of the Cheatham project below Nashville, was closed to navigation on October 15, 1954. Locks and dams 3 and 4 were operated to June 12 and December 18, 1954, respectively, and have been inundated with filling of Old Hickory Reservoir. Op- eration of lock and dam 2 was discontinued on December 5, 1956, and has been demolished with construction of the Old Hickory project, as have locks 5 and 6 which were permanently closed on June 30, 1956. Upon removal of lock and dam 7, scheduled for accomplishment early in the fiscal year 1958, the Old Hickory proj- ect will provide a through channel for 9-foot navigation on the Cumberland above Nashville to the vicinity of Carthage, Tenn., at river mile 308, the present head of navigation. Owing to cessation of river traffic above that locality, lock 8 was placed in an inoperative status on November 30, 1951. New work under the authorized modification of the existing proj- ect for this section of the river, as a whole, was 37 percent complete. Engineering and design were 46 percent complete. Construction of Old Hickory under the modified project was commenced in January 1952, and the contract for the lock and dam structures has been completed. The lock was placed in temporary operation on June 14, 1954, and completed for per- manent operation on September 22, 1956. Work under a con- tinuing contract for construction of the power plant was initiated in March 1954, and was approximately 96 percent complete at the end of the fiscal year. Under the various supply contracts, de- livery has been made on all items of Government-furnished powerhouse equipment. Reservoir clearing under 3 contracts (17,323 acres) has been completed, as have contracts for the following: Relocation of 978 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 affected roads in the five counties involved; relocation of telephone lines of the Southern Bell Telephone Co.; rearrangement and alteration of natural gas lines of the Texas Eastern Transmission Corp. and the East Tennessee Natural Gas Co.; relocation of power lines of the Tennessee Valley Authority; cemetery removals (92 remains) ; relocation of power lines and facilities of Nashville Electric Power Board; relocation of the Hendersonville, Tenn., water plant; relocation of power lines of the Cumberland Electric Membership Corp.; modification of the Lebanon, Tenn., raw water plant; and construction of repair and storage facilities at the project site. Under outstanding contracts, except for demolition of lock and dam 7 on which the notice to proceed was not issued prior to close of the year, work has been brought to the following percentages of completion: Dredging below Old Hickory Dam and demolition of lock and dam 2, 94 percent; removal of locks and dams 5 and 6, 96 percent; and construction of reservoir manager's office and comfort station, 59 percent. Approximately 29,071 acres, or 99.7 percent of the necessary reservoir lands have been acquired: 25,835 acres in fee simple, 2,541 acres in easement, and 695 acres by transfer from another Government agency. The Old Hickory Project, as a whole, was about 95 percent complete. The total new work costs for this section to June 30, 1957, were $49,533,433. The total costs for channel maintenance were $357,611. c. Operation and maintenance of structures: Locks B to F, inclusive, and the new Cheatham and Old Hickory locks were in operation at the end of the year; the structures and appurtenances having been maintained in serviceable condition. The total costs under the existing project for the entire stream were $93,910,583, of which $82,907,473, including $685,000 from public work funds, was for new work, and $11,003,110 for operation and maintenance.

The costs for permanent work were $15,123,219. Existing project. The River and Harbor Act of July 3, 1930 (Public Law 520, 71st Cong., 2d sess.), authorized the permanent improvement of the river for a navigable depth of 9 feet at low water from the mouth to Knoxville, Tenn., a distance of about 650 miles, to be obtained by the construction of low dams; pro- vided, that under the provisions of the Federal Water Power Act a high dam with locks may be substituted for any two or more of the low dams and built by private interests, States, or municipalities; and provided further, that in case high dams are built before the United States shall have built the projected locks and low dams which are to be replaced, the United States shall contribute to the cost of the substituted structures an amount equal to the estimated cost of the work of navigation for which substitution is made. (See H. Doc. 328, 71st Cong., 2d sess.) The estimated cost of the authorized project as contained in House Document 328, 71st Congress, 2d session, exclusive of amounts expended on previous projects, is $74,709,000 for new work and $40,000 annually for the maintenance and operation of each lock and dam. The latest published maps are in the project document. 980 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The above-mentioned act also authorized the appropriation of $5,000,000 for the prosecution of work on this project. The only construction performed by the Corps of Engineers thereunder was the construction of the lock at the General Joe Wheeler Dam and miscellaneous appurtenant improvements. No low dams were constructed under this authorization. The cost of new work completed by the Corps of Engineers is $2,244,236, excluding amounts expended on previous projects. The average annual cost during the past 5 years for operation and maintenance of channels, the 10 locks, and dam 1 (including the locks constructed by the Tennessee Valley Authority and operated by the Corps of Engineers) was $732,000. Under the provisions of the Tennessee Valley Authority Act of 1933, approved May 18, 1933 (Public Law 17, 73d Cong.), as amended by an act approved August 31, 1935, the Tennessee Valley Authority is given power to construct such dams in the Tennessee River as will provide a 9-foot channel and maintain a water supply for same from Knoxville to its mouth. The Tennessee Valley Authority program provided for ob- taining the authorized 9-foot project by the construction of high dams and locks and utilization of certain locks and dams previ- ously constructed under the jurisdiction of the Corps of Engineers. The functions of the Corps of Engineers, since adoption of the Tennessee Valley Authority Act of 1933 have been those of cooperation with the Authority through preparing (with Corps of Engineers forces and funds) the designs of locks at Pickwick, Guntersville, Chickamauga, Watts Bar, and Fort Loudoun Dams; and, in accordance with the general navigation laws placing con- trol and supervision over navigable waters in the Secretary of the Army, the Corps of Engineers: Operates and maintains all locks, lifts, or other facilities in aid of navigation; maintains navigation channels and safety harbors by performing all necessary dredg- ing and snagging operations; examines and passes upon plans for all bridges, wharves, or other structures in navigable waters prior to construction, including construction plans involving the alteration or modification of existing channels; establishes harbor lines where essential to the preservation and protection of har- bors; provides for removal of unlawful structures, including wrecks; cooperates and reviews plans of individuals, corporations -municipal or private-in the improvement of navigable waters at their own expense and risk; issues rules and regulations governing the opening and operation of drawbridges, the trans- portation and dumping of dredgings or other material into navi- gable waters; promulgates rules and regulations governing the use, administration, and navigation of navigable waters, in- cluding harbors thereof; compiles statistics of waterborne com- merce. The division of responsibility regarding the project is outlined in memorandum of agreement dated July 11, 1946, be- tween the Tennessee Valley Authority and the Corps of Engineers.

The River and Harbor Act of July 3, 1930, requires no local cooperation in the construction of the alternate system of low dams. It does, however, provide that in case high dams are built before the United States shall have built the pro- jected locks and low dams which are to be replaced, the United States shall contribute to the cost of the substituted structures an amount equal to the estimated cost of the works of navigation for which substitution is made. Terminal facilities. Public use river terminals with railroad connections, owned by the Tennessee Valley Authority, have been constructed at Decatur and Guntersville, Ala., and Chattanooga and Knoxville, Tenn. River terminals with railroad connections, municipally owned, have been constructed at Sheffield, Ala., and Chattanooga, Tenn. The other public terminals are mostly un- improved landings. Government-owned facilities for the trans- fer of sulfur and toluene are located at Volunteer Ordnance Works, Tyner, Tenn.; and for the transfer of coal and salt at Redstone Arsenal, Greene Grove, Ala., and at the following Tennessee Valley Authority steam-electric powerplants along the river: Colbert, Wilson, and Widows Creek in Alabama; and Hales Bar, Watts Bar, Kingston, and Johnsonville in Tennessee. Railroad inclines and sidings are available at Sheffield, Decatur, Hobbs Island, Guntersville, and Bridgeport, Ala., and Chattanooga, Tenn. Privately owned terminals have been constructed for the transfer of certain commodities as follows: Limestone at Clifton, Bennetts Lake, and Chattanooga, Tenn.; molasses and asphalt at Knoxville, Tenn.; automobiles and miscellaneous merchandise at Guntersville, Ala.; coal at Calvert City and Grand Rivers, Ky., Guntersville, Ala., and Chattanooga, Tenn.; grain at Decatur and Guntersville, Ala., and Chattanooga, Tenn.; petroleum products at Sheffield, Decatur, and Guntersville, Ala., Reidland, Ky., and Perryville, Chattanooga, and Knoxville, Tenn. In addition to the foregoing there are many unimproved private landings along the river. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. No new work was accomplished. Channel work by Government plant and hired labor consisted of replacing 4 pile dolphins. The cost of channel maintenance was $20,434. Operation and maintenance of structures: All locks were operated and lock appurtenances and standby plant were main- tained as required. Maintenance, improvement, and reconstruc- tion work was held to a minimum in compliance with current policy concerning use of critical materials and equipment. Re- pairs were made as follows: Valves and lock lighting system at Pickwick lock; lock wall and upper and middle gates at Wilson lock and valves at Fort Loudoun lock. Work for renewal of sewer lines at Hales Bar lock was initiated. The cost of operation and maintenance of structures was $767,021. The total cost of operation and maintenance, general, during the fiscal year was $787,455. RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 983 Condition at end of fiscal year. The existing project was complete. Construction under the project was commenced in January 1933, when work was initiated on Wheeler lock. With the opening of Kentucky lock for permanent operation in Sep- tember 1944, all projected locks and dams had been completed. affording a navigable depth of 9 feet between the mouth and Knoxville, Tenn. (head of river), except in the lock 1 canal and a short stretch in the upper reaches of Hales Bar pool. Dredging in the canal and the raising of dam 1 and Hales Bar Dam remain- ing under the Tennessee Valley Authority program to provide full project dimensions were completed by that agency in 1948. The table under the paragraph "Existing project" gives the year opened to navigation and other information concerning the 10 locks now in operation. Construction of new and modified navigation features at the Wilson project, to provide for more efficient handling of the in- creasing traffic past the dam, was undertaken by the Tennessee Valley Authority on July 1, 1956, and is currently in progress. The plan of improvement contemplates construction of a new single-lift lock, with larger chamber dimensions (110 x 600 feet) and affording additional lift; provision of auxiliary service, or standby lockage facilities, through alterations to the existing double-lift lock; and, in conjunction with these features, realine- ment and deepening of the navigation canal immediately down- stream to bypass and eliminate the necessity for operation of lock and dam 1. The completed locks were operated and maintained under the permanent indefinite appropriation to the end of the fiscal year 1935, as follows: Hales Bar, since November 1, 1913; lock (and dam) 1, since March 1, 1926; Wilson, since June 1, 1927; and Wheeler, since November 27, 1934. Subsequent to June 30, 1935, operation and maintenance of lock and dam 1, Hales Bar, Wilson, and Wheeler locks have been carried on with funds appropriated for the preservation and maintenance of river and harbors, as well as the following: Pick- wick Landing lock, since September 1, 1937; Guntersville lock, since September 1, 1937; Chickamauga lock, since October 15, 1937; Watts Bar lock, since March 3, 1941; Kentucky lock, since February 10, 1942; and Fort Loudoun lock, since October 10, 1943.

MIDDLESBORO, CUMBERLAND RIVER BASIN, KY. Location. This project is located at Middlesboro, Ky., on Yel- low Creek, a tributary entering the Cumberland River about 660 miles above its mouth. Existing project. The improvement provides for a system of canals and levees around one side of the town, arranged so as to divert most of the headwaters of Yellow Creek away from the present channel through the heart of the city. The series of canals and levees are about 4 miles in length, beginning on Ben- netts Fork at the western edge of the town and ending at Yellow Creek near the Middlesboro Tannery at the northern edge of the town. The cuts involved excavation of approximately 695,000 cubic yards of material, of which about 410,000 cubic yards were FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 985 utilized in the levee system. Besides construction of the diversion channel, there was other incidental work, which included the installation of cuverts and the relocation and rebuilding of road- ways and bridges. The project diverts from the business district and from a large part of the residental section the floodwaters which originate in that part of the basin lying north and west of the city, thus affording protection, in a large measure, to life and property from these headwater floods which cause the greatest damage. The project was authorized by the Flood Control Act approved June 22, 1936. The cost of the completed project is $817,830. The average annual maintenance cost during the past 5 years was $7,000. Local cooperation. None required. Operations and results during fiscal year. New work: None. Maintenance: Levees, canals, and appurtenances were main- tained by hired labor at a cost of $4,912. Operation of the project during the 1956-57 flood season resulted in the prevention of damages estimated as $299,000. Condition at end of fiscal year. New work under the existing project was completed in March 1945, when final settlement was made with the city of Middlesboro in connection with the acquisi- tion and transfer to the United States of rights-of-way and flow- age easements. Construction of the canal and levee system, ini- tiated in May 1938, was completed and the improvement placed in operation in December 1939. Relocation work was completed in September 1940. The total costs to June 30, 1957, were $892,361, of which $817,830, including $38,876 from emergency relief funds, was for new work and $74,531 for maintenance. In addition surplus prop- erty valued at $4 was transferred to the project without reimbursement.

PINEVILLE, CUMBERLAND RIVER BASIN, KY. Location. This project is located at Pineville, Ky., on the Cum- berland River about 655 miles above the mouth. Existing project. The plan of improvement comprises the con- struction of a system of earth levees and concrete floodwalls, with appurtenant facilities, to afford protection for the city and its residential suburb, Wallsend, against a flood equal in magnitude to the maximum of record (1946). The freeboard allowance is 986 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 5 feet for the upstream section of the proposed works above Pine Street Bridge, and 3 feet downstream. Protection for Pineville proper is to be provided by about 6,175 feet of concrete walls and a relatively short levee section, 250 feet in length, beginning at a connection with United States Highway No. 25E near the up- stream limit of the city and following in general the top of the left bank of the Cumberland River to terminate in the approach to the Tennessee Avenue (Pineville-Wallsend) Bridge. Raising of the bridge and the provision of ramps or gated structures at necessary highway and street crossings will maintain access to the protected area. Two pumping stations, with appurtenant out- let works and intercepting sewers, will provide for the disposal of interior drainage. Including extension of a roadway ramp to high ground south of the intersection of United States Highway No. 25E with the Tennessee Avenue Bridge approach, the overall reach of the structures in the Pineville section of the project ap- proximates 6,800 feet. On the right bank of the river provision is made for about 3,660 feet of earth levee to partially encom- pass Wallsend, beginning and terminating within a distance of 1,500 feet in the embankment of the Louisville & Nashville Rail- road which runs along the northern edge of the community. In- cidental construction in this section includes necessary ramp crossings, sewer modifications and one pumping station. The project was authorized by the Flood Control Act approved June 22, 1936. The estimated Federal cost of new work (July 1957) is $1,670,000; the estimated non-Federal cost is $460,000. Local cooperation. Assurances of local cooperation were ac- cepted by the Corps of Engineers on May 5, 1953. Bonds in the amount of $200,000 of an issue voted for financing the city's share of the project costs were sold on January 5, 1953, and the acquisi- tion of necessary lands and rights-of-way initiated. Additional bonds in the amount of $250,000 were sold on February 1, 1954. All properties affected by the construction works have been acquired. During the fiscal year 1956, funds were contributed by the city of Pineville in the amount of $9,950 to cover additional costs to be incurred as a result of a change in the plan of improvement to provide, in accordance with the desires of local interests, for the construction of a floodwall structure in lieu of a 230-foot levee section previously contemplated at the upstream end of the proj- ect between United States Highway No. 25E and Cumberland Avenue. Operations and results during fiscal year. A contract for con- struction of Unit 4-Wall and Closure Structures (Pineville section) was initiated and completed, with the following quantities of major items of work having been accomplished: Excavation, 720 cubic yards; compacted backfill, 190 cubic yards; random fill, 225 cubic yards; steel sheet piling, 60 tons; concrete placed, 318 cubic yards; reinforcing steel, 17,990 pounds; bumper guards, 1,065 feet; 8-inch sewer pipe, 490 feet; 6-inch corrugated metal pipe, 28 feet; toe drain, 320 feet; compacted fill, 325 cubic yards; dumped rock fill, 220 tons; bituminous mixture binder course, 87 FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 987 tons; bituminous surface course, 40 tons; 24-inch corrugated metal culvert, 58 feet; 54-inch reinforced concrete pipe, 246 feet; and 6-inch sanitary sewer pipe, 220 feet. Unit 4 consisted pri- marily of a wall section about 380 feet in length, including a gated opening for United States Highway No. 25E, remaining to be constructed at the upstream end of the works for completion of the floodwall feature of the project; and also provided for permanent closure of a 25-foot gate opening left in the Unit 1 Floodwall at the Kentucky Avenue Bridge, since abandoned. Work was initiated and brought to about 94 percent completion under a con- tinuing contract awarded during the year pursuant to an agree- ment entered into with the Commonwealth of Kentucky, Depart- ment of Highways, providing for reimbursement by the Govern- ment of costs for adjustment of the intersection of United States Highway No. 25E and Tennessee Avenue of the lower limit of the project, including bridge approach and construction of a roadway ramp extension to high ground. A continuing contract for construction of the Wallsend levee, including provision for raising the Tennessee Avenue (Pineville- Wallsend) Bridge, also was completed. In addition to outlet works and bridge alterations, the approximate quantities of major items of work performed were: Clearing and grubbing, 5 percent; stripping and excavation, 5,200 cubic yards; borrow excavation, 41,345 cubic yards; levee embankment, 68,525 cubic yards; hand- placed riprap, 345 cubic yards; sewer pipe installed, 712 feet (8- inch, 174 feet; 24-inch, 312 feet; 30-inch, 226 feet); 48-inch cul- vert pipe, 147 feet; concrete sidewalks, 184 square yards; header curb, 283 feet; 4-inch traffic-bound surfacing, 625 square yards; 8-inch water-bound macadam base, 960 square yards; and 2-inch bituminous surfacing, 960 square yards.

Existing project. The plan of improvement provides for the construction of local flood protection works at Barbourville, Ky., which consist principally of a system of levees having an average height of 15 feet, beginning at a point where branches of the Louisville & Nashville Railroad enter the main line northeast of town and following in general the top of bank of Richland Creek and the Cumberland River a distance of about 18,500 feet to terminate into the Louisville & Nashville Railroad embankment southeast of the town. Provision for a low area immediately across the railroad consists of regarding an adjoining high knoll and construction of a concrete and steel pile I-type wall, about 290 feet in length, having a gated opening to pass United States High- way No. 25E and extending to high ground beyond. Other inci- dental construction includes nine gravity outlet structures and four combined gravity outlets and pump stations, with intercepting ditches or pipelines, for disposal of interior drainage; a gated opening for Kentucky State Highway No. 459; and five ramps at road and street crossings. The proposed works will afford pro- tection for the town against the greatest flood of record (1946) with a freeboard of 3 feet. The project was authorized by the Flood Control Act approved May 17, 1950. The estimated cost of new work (July 1957) is $1,780,000 for construction (Federal) and $265,000 for lands and damages (non-Federal). Local cooperation. The plan of improvement and the require- ments of cooperation were first discussed at a meeting with local interests on May 18, 1948. Formal assurances of cooperation, attested by an instrument executed by the city of Barbourville on August 13, 1953, were accepted by the Corps of Engineers on FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 989 September 9, 1953. Bonds in the amount of $130,000 of an issue voted for financing the city's share of the project costs were sold on August 31, 1954, and the acquisition of necessary lands and rights-of-way initiated. Additional bonds in the amount of $130,000 were sold on February 23, 1956. Properties affected by completed works and construction underway have been acquired. Operations and results during fiscal year. Construction opera- tions were continued with accomplishment of the following quan- tities of major items of work under the contract for Levee Unit 1: Excavation, common and borrow, 26,475 cubic yards; levee em- bankment, 27,015 cubic yards; filter blanket, 950 cubic yards; hand-placed riprap, 2,325 cubic yards; steel reinforcement and miscellaneous metal, 4,800 pounds; placement of 98 feet of 16-inch corrugated iron pipe; traffic-bound surfacing, 102 square yards; water-bound macadam base, 240 square yards; 2-inch bituminous surfacing, 240 square yards; 3-inch stone insulating course, 35 square yards; integral and header curb, 90 lineal feet; and concrete sidewalk, 155 square yards. This unit embraces 6,685 feet of levee and related drainage facilities, including pump- ing plant outlets, beginning at a point about 350 feet downstream from the Walker Park (Kentucky Highway No. 439) Bridge across Richland Creek, then following the creek and main stream to the tie-in with the railroad embankment southeast of the city. Under a continuing contract initiated during the year for con- struction of Levee Unit 2 (remaining embankment and appur- tenances), the approximate quantities of work performed were: Clearing and grubbing, 90 percent; excavation, stripping, 40,000 cubic yards; excavation, common and borrow, 117,000 cubic yards; levee embankment, 15,000 cubic yards; concrete placed, 590 cubic yards; steel reinforcement and miscellaneous metal, 88,000 pounds; placement of 565 feet of sewer pipe (8-inch, 165 feet; and 12-inch, 400 feet); 24-inch culvert pipe, 445 feet; 24-inch bituminous coated metal pipe, 108 feet; and excavation for outlet structures, 76,000 cubic yards. Hired labor operations included completion of plans and speci- fications for Levee Unit 2, contracted during the year; preparation and issuance of such for the Walker Street gated closure structure; and essential completion of engineering and design studies for pumping stations and the floodwall feature of the project. During a flood experienced in January-February 1957, the partially completed levee system protected the town from destruc- tive current and lowered the water level at some points as much as 1.5 feet, resulting in the prevention of damages estimated as $50,000. The costs during the year for new work were $437,342. Condition at end of fiscal year. Construction of the project was commenced in June 1955. With the completion of Levee Unit 1 and about 44 percent completion of Unit 2 during the fiscal year, the project as a whole was 52 percent complete. Engineering and design were 81 percent complete. The total costs to June 30, 1957, were $925,722. 990 REPORT OF THE CHIEF OF ENGINEERS, U. S.

LAKE CUMBERLAND (WOLF CREEK DAM), OHIO RIVER BASIN, KY. Location. Wolf Creek Dam is located on the Cumberland River at mile 460.9 (above mouth) in Russell County, Ky., about 10 miles southwest of Jamestown and 12 miles north of Albany, Ky. Lake Cumberland, formerly Wolf Creek Reservoir, extends 101 miles up the main stream, 48 miles up the South Fork of Cum- berland River, and lies within Russell, Clinton, Wayne, Pulaski, McCreary, Laurel, and Whitley Counties, Ky. Existing project. The plan of improvement provided for the construction of a combination earth and concrete gravity-type dam, 5,736 feet long and 258 feet in height above its lowest foundation; and a hydroelectric power-generating plant. The dam consists of a rolled-earth embankment section extending 3,940 feet from the right abutment across the flood plain portion of the valley, and a concrete structure, 1,796 feet in length, comprised of spillway, power intake, and adjacent nonoverflow sections, con- necting the embankment with the left abutment. The spillway contains six gate-controlled conduits and is surmounted with 10 tainter crest gates to provide for regulating and discharging flood- flows. The powerhouse, a reinforced concrete structure of the conventional indoor type, is located directly at the downstream base of the power intake section of the dam through which six penstocks were constructed. The power installation consists of six 45,000 kilowatt generating units. The project is one unit of a coordinated plan for the control of floods and the development of the water resources of the Cumberland River Basin, this plan in turn forming an integral part of the comprehensive plan of de- velopment for the Ohio and Mississippi Rivers. At maximum controlled pool level, top of spillway crest gates, the reservoir covers an area of 63,530 acres and provides a storage capacity of 6,089,000 acre-feet, of which 2,094,000 is allocated for flood con- trol and 2,142,000 for power drawdown, leaving a minimum pool of 1,853,000 acre-feet available at all times for public use and conservation purposes. The drainage area controlled is 5,810 square miles or approximately one-third of the Cumberland River Basin. The project was selected for construction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938, and the additional FLOOD CONTROL--NASHVILLE, TENN., DISTRICT 991 authorization contained in the River and Harbor Act approved July 24, 1946, under the title "Wolf Creek Reservoir." Public Law 323, 82d Congress (2d sess.), approved April 17, 1952, pro- vided upon enactment that the lake formed by the waters im- pounded by Wolf Creek Dam, Ky., should thereafter be known and designated on the public records as Lake Cumberland. The estimated cost of the project, including the six-unit power installation, is $79,060,000 (July 1957). The average annual operation and maintenance cost during the past 5 years was $318,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operation and results during fiscal year. New work: Cor- rective work with respect to improvement of the power plant transil oil system, contracted just prior to the close of fiscal year 1956, was completed. Several minor construction items pertain- ing to the dam and the comfort station at the project site were accomplished by hired labor. Real estate activities consisted of completing legal action on all except one pending condemnation cases on mineral interests; acquiring fee title to an island tract affected by flows from maximum power production; continuation of action to acquire flowage easement over 5,324 acres of land from another Government agency; and the preparation of two litigation reports on Court of Claims cases. Operation and maintenance: The dam was operated and the structures and appurtenances maintained as required. Operation of the powerplant was continuous except for normal interruptions and necessary shutdowns for inspection and maintenance purposes. Under existing regulations, the total net energy generated (966,900,000 kilowatt-hours) was made available through the Department of the Interior to the Tennessee Valley Authority for distribution. Regulation of the reservoir during the year was limited to re- leases for the generation of power, except during the period February 11-March 13, 1957, when gate releases were made to supplement turbine discharge in emptying the flood-control portion of the reservoir. The maximum release of 27,470 cubic feet per second was made on March 5, 1957. The average pool elevation was 710.1 feet, which is 12.9 feet below the spillway crest level. Reservoir storage varied from a minimum of 2,248,000 acre-feet on December 12, 1956, corresponding to a pool elevation of 683.6 feet, to a maximum of 4,588,000 acre-feet on February 13, 1957, cor- responding to elevation 734.4. During the occurrence of a flood on the Cumberland River in January and February 1957, the com- bined effect of this project and the Dale Hollow and Center Hill Reservoirs resulted in computed crest reductions of 22.4 feet at Celina, Tenn.; 25.6 feet at Carthage, Tenn.; 13.6 feet at Nashville, Tenn.; 8.9 feet at Clarksville, Tenn.; and 7.5 feet at Dover, Tenn. The Lake Cumberland share of the damages prevented by these operations, including the average annual benefits credited to the project as its share of the reservoir system effect in the reduction 992 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of flood flows on the lower Ohio and Mississippi Rivers, is estimated to be approximately $4,360,000. Activities under the reservoir management program, comprising shoreline sanitation, malaria control, conservation, land manage- ment and disposal, and operation and maintenance of public-use facilities were continued. The costs were $365,248, of which $38,957 was for new work and $3.26,291 for operation and maintenance. Condition at end of fiscal year. The project as a whole was 99 percent complete. Construction of right and left bank access roads and the provision of a temporary construction camp at the project site for Government inspection personnel were completed during early stages of the project. Work under the original con- tract for construction of the dam and appurtenant works was begun in August 1941, but was terminated in 1943 in interest of the war effort, when only about 8 percent complete. Under a new continuing contract awarded for completion of the dam, work was commenced in September 1946 and completed in August 1951. Closure of the dam was effected in December 1950, at which time the project was placed in operation for flood control. The power- plant was constructed during the period November 1949-March 1953, with the six power units being placed in operation on the following dates: October 6, 1951; October 31, 1951; December 16, 1951; March 17, 1952; July 24, 1952; and August 22, 1952. Reservoir operations including mapping (731 square miles), clearing (48,775 acres), removal and salvage of improvements (91,475 acres), and necessary relocations have been completed. Acquisition has been completed on 92,759 acres in fee simple and 579 acres in easement. Disposal action has been completed on 64 acres in fee, and 114 acres in easement. The principal items of work remaining for full accomplishment of the project involve settlement of pending claims, and other rel- atively minor activities, under the land acquisition propram; necessary changes in powerhouse equipment (centralization of controls) ; and completion of project "as-constructed" drawings.

Dale Hollow Dam is located on the Obey River 7.3 miles above its confluence with the Cumberland River (mile 380.9) at Celina, Tenn. It is in Clay County, Tenn., and is about 80 miles northeast of Nashville, Tenn., 28 miles north of Cookeville, Tenn., 13 miles west of Byrdstown, Tenn., and 3 miles east of Celina, Tenn. Dale Hollow Reservoir extends about 51 miles up the main stream, 10 miles up the East Fork, and 6 miles up the West Fork of Obey River, and lies within Cumberland and Clinton Counties, Ky., and Clay, Pickett, Overton, and Fentress Counties, Tenn. Existing project. The plan of improvement provided for con- struction of a concrete gravity-type dam, 1,717 feet long and 200 feet in height above its lowest foundation; and a hydroelectric power-generating plant. The dam consists of spillway and power intake sections across the flood plain portion of the valley width, flanked by nonoverflow transition sections terminating in the abutments. Four gate-controlled conduits through the base of the spillway section and six tainter crest gates provide for regu- lating and discharging flood flows. The powerhouse, a reinforced concrete structure of the conventional indoor type, is located directly at the downstream base of the power intake section of the dam through which three penstocks were constructed. The power installation consists of three 18,000-kilowatt generating units. The project is one unit of a coordinated plan for the con- trol of floods and the development of the water resources of the Cumberland River Basin, this plan in turn forming an integral part of the comprehensive plan of development for the Ohio and Mississippi Rivers. At maximum controlled pool level, top of spillway crest gates, the reservoir covers an area of 30,990 acres and provides a storage capacity of 1,706,000 acre-feet of which: 353,000 is allocated for flood control and 496,000 for power draw- down, leaving a minimum pool of 857,000 acre-feet available at all times for public use and conservation purposes. The drainage area controlled is 935 square miles or 99 percent of the Obey River Basin. The project was selected for construction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938, and the additional authorization contained in the River and Harbor Act approved July 24, 1946. The cost of the completed project is $25,920,368. The average annual operation and maintenance cost during the past 5 years was $241,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. New work: None ; minor current fiscal year costs only were incurred in connection with orders placed but undelivered as of June 30, 1956. 994 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Operation and maintenance: The dam was operated and the structure and its appurtenances maintained as required. Opera- tion of the powerplant was continuous during the year except for normal interruptions and necessary shutdowns for inspection and maintenance purposes. Under existing regulations, the total net energy generated (124,322,000 kilowatt-hours) was made avail- able through the Department of the Interior to the Tennessee Valley Authority for distribution. Regulation of the reservoir during the year was limited to re- leases for the generation of power, with a maximum release for this purpose of 5,800 cubic feet per second. The average pool ele- vation was 644.2 feet, which is 6.8 feet below the spillway crest level. Reservoir storage varied from a minimum of 938,000 acre- feet on December 11, 1956, corresponding to a pool elevation of 634.6 feet, to a maximum of 1,345,000 acre-feet on February 11, 1957, corresponding to elevation 650.7. During the occurrence of a flood on the Cumberland River in January and February 1957, the combined effect of this project and the Lake Cumberland (Wolf Creek) and Center Hill Reservoirs resulted in computed crest reductions of 22.4 feet at Celina, Tenn.; 25.6 feet at Carthage, Tenn.; 13.6 feet at Nashville, Tenn.; 8.9 feet at Clarksville, Tenn.; and 7.5 feet at Dover, Tenn. The Dale Hollow Reservoir share of the damages prevented by these operations, including the average annual benefits credited to the project as its share of the reservoir system effect in the reduction of flood flows on the lower Ohio and Mississippi Rivers, is estimated to be approximately $2,164,000. Activities under the reservoir management program, comprising shoreline sanitation, malaria control, conservation, land manage- ment and disposal, and operation and maintenance of public-use facilities were continued. The costs were $235,055, of which $153 was for new work and $234,902 for operation and maintenance. Condition at end of fiscal year. The project was complete. Work under the contract for construction of the dam and its ap- purtenances was initiated in March 1942, and final closure of the dam was effected in October 1943, at which time the project was placed in operation for flood control. The powerplant, with two 18,000-kilowatt generating units (initial development) in commer- cial operation, was completed in April 1949. Generating units Nos. 1 and 2 were placed on the line December 18, 1948, and Jan- uary 26, 1949, respectively. Installation of the third and final generating unit (initiated in March 1952) was completed in De- cember 1953, with the unit having been placed in commercial operation on November 17, 1953. Reservoir operations included mapping (258 square miles), clearing (17,168 acres), removal and salvage of improvements, re- locations, and development of management and public-use facili- ties. Construction of relocated Tennessee Highway No. 42 Bridge, removal of six highway bridges, relocation of 2,293 graves, and clearing of 10,179 acres of the reservoir area were accomplished by contract. FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 995 All lands required for project purposes, totaling 52,496 acres, have been acquired; comprising 52,405 acres in fee simple, 89 acres of flowage easements, and 2 acres of road easements. Disposal action has been taken on 1.55 acres of road easements. The total costs to June 30, 1957, were $28,106,121, of which $25,920,368 was for new work and $2,185,753 for operation and maintenance.

CENTER HILL RESERVOIR, OHIO RIVER BASIN, TENN. Location. The site of the Center Hill Dam is on the Caney Fork River, 26.6 miles above its confluence with the Cumberland River (mile 309.2) at Carthage, Tenn. It is in DeKalb County, Tenn., and is about 55 miles east of Nashville, Tenn., 30 miles north of McMinnville, Tenn., 20 miles west of Cookeville, Tenn., and 14 miles southeast of Carthage, Tenn. Center Hill Reservoir extends about 64 miles up the main stream and about 10 miles up Falling Water River and lies within DeKalb, Putnam, White, and Warren Counties, Tenn. Existing project. The plan of improvement provided for con- struction of a combination earth and concrete gravity-type dam, 2,160 feet long and 250 feet in height above its lowest foundation; and a hydroelectric power-generating plant. The dam consists of a rolled-earth embankment section extending 778 feet from the left abutment across the flood plain portion of the valley, and a concrete structure 1,382 feet in length, comprised of spillway, power intake, and adjacent nonoverflow sections, connecting the embankment with the right abutment. The spillway contains six gate-controlled conduits and is surmounted with eight tainter crest gates to provide for regulating and discharging floodflows. In addition to the main dam structure, the project provided for construction of a rolled-earth dike, 770 feet in length, to close a saddle in the reservoir rim on the right bank near the dam site. The powerhouse, a reinforced concrete structure of the conven- tional indoor type, is located directly at the downstream base of the power intake section of the dam through which three pen- stocks were constructed. The power installation consists of three 45,000 kilowatt generating units. The project is one unit of a coordinated plan for the control of floods and the development of 996 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the water resources of the Cumberland River Basin, this plan in turn forming an integral part of the comprehensive plan of development for the Ohio and Mississippi Rivers. At maximum controlled pool level, top of spillway crest gates, the reservoir covers an area of 23,060 acres and provides a storage capacity of 2,092,000 acre-feet, of which 762,000 is allocated for flood control and 492,000 for power drawdown, leaving a minimum pool of 838,000 acre-feet available at all times for public use and con- servation purposes. The drainage area controlled is 2,195 square miles, or approximately four-fifths of the Caney Fork River Basin. The project was selected for construction under the general au- thorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938 and the additional authorization con- tained in the River and Harbor Act approved July 24, 1946. The estimated cost of the project, including the 3-unit power installa- tion, is $44,351,000 (July 1957). The average annual operation and maintenance cost during the past 5 years was $245,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. New work: Ac- quisition was completed on an additional 26 acres of the easement area below the dam which are damaged by flows from maximum power production. Legal action in connection with pending con- demnation cases was continued and final judgments were entered on 10 cases. Other operations consisted of engineering and design studies concerning foundation relief piping in dam and powerhouse structures. Operation and maintenance: The dam was operated and the structure and its appurtenances maintained as required. Opera- tion of the powerplant was continuous except for normal interrup- tions and necessary shutdowns for inspection and maintenance purposes. Under existing regulations, the total net energy gener- ated (339,997,000 kilowatt-hours) was made available through the Department of the Interior to the Tennessee Valley Authority for distribution. Activities under the reservoir management program, comprising shoreline sanitation, malaria control, conservation, land manage- ment and disposal, and operation and maintenance of public-use facilities were continued. Regulation of the reservoir during the year was limited to re- leases for the generation of power, except during the period Feb- ruary 3-February 16, 1957, when gate releases were made to supplement turbine discharge in emptying the flood-control portion of the reservoir. The maximum release of 29,990 cubic feet per second was made on February 5, 1957. The average pool elevation was 638.8 feet, which is 9.2 feet below the spillway crest level. Reservoir storage varied from a minimum of 933,000 acre-feet on January 21, 1957, corresponding to a pool elevation of 624.4 feet, to a maximum of 1,618,000 acre-feet on February 3, 1957, cor- responding to elevation 663.0. During the occurrence of a flood on the Cumberland River in January and February 1957, the com- bined effect of this project and the Lake Cumberland (Wolf FLOOD CONTROL--NASHVILLE, TENN., DISTRICT 997 Creek) and Dale Hollow Reservoirs resulted in computed crest re- ductions of 22.4 feet at Celina, Tenn.; 25.6 feet at Carthage, Tenn.; 13.6 feet at Nashville, Tenn.; 8.9 feet at Clarksville, Tenn.; and 7.5 feet at Dover, Tenn. The Center Hill Reservoir share of the damages prevented by these operations, including average annual benefits credited to the project as its share of the reservoir system effect in the reduction of flood flows on the lower Ohio and Mississippi Rivers, is estimated to be approximately $2,810,000. The costs were $264,012, of which $21,742 was for new work and $242,270 for operation and maintenance. Condition at end of fiscal year. The project as a whole was 99 percent complete. Work under the contract for construction of the dam, appurtenant works, and access roads was begun in March 1942, but was suspended in March 1943 in interest of the war effort, when about 40 percent complete. Operations were resumed in January 1946. Closure of the dam was effected in November 1948, at which time the project was placed in operation for flood control. Work under the prime contract as modified to include construction of the powerplant was completed in November 1951. Generator units Nos. 1, 2, and 3 were put in service commercially on December 11, 1950, January 17, and April 11, 1951, respectively. Reservoir operations included mapping (178 square miles), clearing (15,850 acres), removal and salvage of improvements, cemetery romovals, and relocation of Tennessee State Highway Nos. 2'6 (Sligo) and 56 bridges. All necessary reservoir lands have been acquired; 37,744 acres having been obtained in fee simple, 87 acres in road and flowage easements, and 829 acres by transfer from another Government agency. In addition, 394 acres of 521 authorized for acquisition in easement below the dam because of damages incurred from project operation have been acquired. Disposal action on transfer of 79 acres in road easements to the State of Tennessee has been completed. Work yet to be accomplished under the project involves fulfill- ment of the remaining lands requirements, including settlement of claims pending in court, and installation of foundation relief piping in the dam and powerhouse structures.

The project is located at Lake City, Tenn., on Coal Creek, which rises in northern Anderson County, Tenn., flows northeasterly and easterly about 12 miles, and discharges into the Clinch River (a tributary of the Tennessee River) at a point about 5 miles downstream from Norris Dam and 20 miles northwest of Knoxville, Tenn. Existing project. The plan of improvement provides for local flood protection at and in the vicinity of Lake City, Tenn., by en- largement and rectification of the stream channel to obtain a bot- tom width of 100 feet from a point near the upstream corporate limits, extending through the town and downstream therefrom for a total distance of about 2.5 miles; provision also being made for a supplementary cutoff, having a bottom width of 20 feet, across the narrow portion of a bend in the creek just downstream of the channel improvement. Incidental work includes alterations to bridges and sewers and construction of a new bridge across the cutoff. Authorized by the Flood Control Act approved Sep- tember 3, 1954 (Public Law 780, 83d Cong., 2 sess.), in accordance with House Document 154, 82d Congress, 1st session, the project is designed to afford protection against a flood approximately 50 percent greater than the maximum of record (1929). The esti- mated cost of new work (July 1957) is $655,000 for construction, Federal; and $105,000 for lands and damages, non-Federal. Local cooperation. The project was adopted subject to the or- dinary requirements of local cooperation, with respect to lands and damages and maintenance of the works of improvement, and on the further condition of local interests assuming responsibility for the prevention of encroachment upon the rectified stream channel after completion. The plan of improvement was sub- mitted to and discussed with members of the city council on October 5, 1949, prior to final compilation and processing of the authorization document, at which time approval of the proposed works and assurances of compliance with the conditions of local participation were expressed. In anticipation of a favorable proj- ect, local interests had legislation passed by the General Assembly of the State of Tennessee which, along with other provisions, em- powers the Board of Commissioners of Lake City to levy taxes on all taxable property for purposes of financing the city's share of the project costs. Formal and final assurances of cooperation were furnished by the Mayor pursant to a resolution adopted at a regular meeting of the city council on January 14, 1957, and were accepted by the Corps of Engineers on April 4, 1957. Operations and results during fiscal year. Definite design stud- ies comprising investigations and preliminary designs required for definition of overall features of the project were initiated and essentially completed at a new work cost of $15,210. FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 999 Condition at end of fiscal year. Construction of the project has not been commenced. Engineering and design were about 38 percent complete.

PAINT ROCK RIVER, ALA. Location. Paint Rock River, a tributary of the Tennessee River, is formed by the confluence of Estill and Hurricane Forks, in the northwest corner of Jackson County, Ala., flows generally south about 60 miles and empties into Wheeler Reservoir at a point 5.8 miles below Guntersville Dam and 12 miles northwest of the town of Guntersville, Marshall County, Ala. Existing project. Improvement of Paint Rock River for flood control and related purposes was authorized by the Flood Control Act approved September 3, 1954 (Public Law 780, 83d Cong., 2d sess.), in general accordance with the recommendations of Senate Document 161, 83d Congress, 2d session, subject to certain condi- tions of local cooperation. The principal features of the project consist of clearing the main stream of snags and obstructions, removal of timber along the banks, and excavation of the channel at critical points, combined with a drainage system to be con- structed by local interests. The plan provides for clearing, clean- ing, and minor straightening of the channel of Paint Rock River for a distance of about 53 miles, extending from about mile 7 (above mouth) to its head at the junction of Hurricane and Estill Forks; and for similar work within the lowermost reaches of the principal tributary streams as follows: Little Paint Creek, 4.8 miles; Guess Creek, 1.8 miles; Hurricane Fork, 2.1 miles; Larkin Fork, 2.5 miles; and Estill Fork, 3.0 miles. These improvements are designed to afford an outlet adequate to permit the undertak- ing by local interests of drainage and related works on some 27,000 acres of land within the watershed. Flows resulting from the more rapid concentration of runoff from the upstream drain- age works will be accommodated by the improved channel without raising crest elevations over those occurring under natural con- ditions. Major benefits will result from increased net returns from agricultural lands and reduced maintenance on existing improvements. 1000 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The current (July 1957) estimate of total cost for the project is $3,212,000, of which $1,881,400 is for the upstream drainage works, to be provided entirely by local interests, and $1,330,600 for the work on the main stream and tributary channels to be provided jointly by local interests and the United States with the costs thereof to be shared as follows: $1,184,000 for construction, Federal; and $146,600 for lands and damages, non-Federal. Local cooperation. The authorizing act specified that the pro- visions of the Flood Control Act approved June 22, 1936, as amended, pertaining to the ordinary conditions of cooperation with respect to lands and damages and maintenance of the works of improvement after completion, shall apply; and that local in- terests shall also construct and maintain local drainage works re- quired to fully and effectively utilize the improved outlet system. Prior to and at several meetings subsequent to authorization, in which the plan of improvement and the requirements of local cooperation were discussed, local interests expressed willingness to participate to the full extent of their ability and have voiced approval of continuing action in furtherance of the project. Action has been initiated toward establishment of a drainage district or similar body to assume full local responsibility and to determine the legal steps necessary in implementing its formation.

Costs were incurred in the amount of $15,014 for engineering and economic studies con- cerned with revaluating the approved project plans for Middles- boro (Yellow Creek), Ky., and Stewarts Ferry Reservoir, Tenn. Condition at end of fiscal year. The status of the Center Hill, 1002 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Dale Hollow, and Lake Cumberland (Wolf Creek) projects, se- lected for construction under this authorization, is given in individual reports. The remaining projects under the comprehensive plan within the Nashville District have been deferred for restudy. Detailed plans previously developed for Three Islands and Rossview Reser- voirs are subject to certain supplementary studies and investiga- tions, and consequent revisions, to reflect current conditions and engineering practices. Mapping of the reservoir area (213 square miles), reservoir area-capacity determinations, and additional foundation exploration work for further site analysis studies in- cident to revision of the Three Islands project plans have been completed. Engineering and design for Stewarts Ferry Reser- voir were discontinued in fiscal year 1953, when about 40 percent complete. Further work on the Middlesboro (Yellow Creek), Ky., local protection project was deferred upon completion of definite design studies in fiscal year 1949. In view of known changes in economic development and recent expressions of con- certed local interest studies for revaluation of the plan of im- provement for the latter project were undertaken during the fiscal year ending June 30, 1956, and have been brought to about 90 percent completion. A restudy of the Stewarts Ferry project in the light of existing conditions of development and prices, includ- ing consideration of recent flood experience, was initiated during the current fiscal year and brought to 85 percent completion. The total costs to June 30, 1957, were $535,360.

KENTUCKY RIVER, KY. Location. The Kentucky River is formed by the confluence of its North and Middle Forks about 4 miles east of the town of Beattyville in east central Kentucky, the South Fork joining the 1005 1006 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 main stream at that place, and flows in a general northwesterly direction 258.6 miles and empties into the Ohio River at Carroll- ton, Ky., mile 545.8 below Pittsburgh, Pa. (See U. S. Geological Survey Chart for State of Kentucky; scale, 1: 500,000.) Existing project. The project provides for 14 locks and fixed dams to give in connection with the improvement of the Ohio River, slack water navigation of 6 feet minimum depth from the Ohio River to points on the three forks a short distance above Beattyville, Ky. The length of the 6-foot-depth project on the main system of the Kentucky River is 258.6 miles to the confluence of the Middle and North Forks. The river frequently rises to a height of 35 feet or more. Extreme flood height at lock 1 due to backwater from Ohio River when in flood is 60.3 feet, while ex- treme floods reach a height of 47.6 feet at lock 4, and 35.5 feet at lock 14. At some intermediate locks the extreme height of floods exceeds 40 feet. All flood heights are referred to upper pool gages. The cost of new work for the completed project, which con- templated the rehabilitation of the 5 State locks and dams and the extension of slack water to the three forks at Beattyville, was $4,176,749. The average annual maintenance and operation cost during the past 5 years was $293,979. The existing project was adopted by the River and Harbor Act of March 3, 1879, in accordance with the report published in House Executive Document 47, 45th Congress, 3d session (Annual Re- port, 1879, p. 1398). Operation and care of the locks and dams were included in the project July 1, 1935, under the provisions of the Permanent Appropriations Repeal Act, approved June 26, 1934. No project map of the river has been published. The statement on page 1007 shows the characteristics of the several locks and dams in this project: Terminal facilities.

Condition at end of fiscal year. The existing project was com- pleted in 1917. The work accomplished under the project has been the rehabilitation of the five old State locks and dams and the construction of new locks and dams Nos. 6 to 14, inclusive. The year of completion of the various locks and dams is given in the table in the paragraph "Existing project." The canalization system of the Kentucky River is in poor con- dition. Repairs have been made to the deteriorated locks and dams as required to keep the locks in operation and to maintain pool levels above the dams except in extreme dry weather, when some pools fall below normal levels. Channel work has been performed as required to relieve critical hardship conditions for existing river traffic. The controlling navigable depth in the section covered by the existing project was 6 feet at the end of the fiscal year. All locks were staffed with two employees each for the lockage of the limited amount of commercial traffic using the river.

The authorization required local interests to release necessary land under their control at no cost to the United States and give assurances that they would prevent future channel encroachment below the dam site in connection with the flood control reservoir. For enlargement of the reservoir to in- clude a conservation pool, local interest would contribute one-half the additional cost of such pool, including one-half the cost of relo- cation of sanitary sewer, and agree to hold and save the United States free from damages resulting from its provision. The board 1018 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of county commissioners of Hamilton County, Ohio, adopted a resolution on October 8, 1947, signifying willingness to fulfill local cooperation requirements including the provision of the con- servation pool. Assurances of local cooperation were executed on the same date. A contract with the United States for the relocation of the sanitary sewer outside the reservoir area in order to include the conservation pool in the project was accepted by Hamilton County, in which the United States paid one-half the cost of such relocation work. The amount of $50,000, required as a local contribution toward the additional cost of providing the conservation pool, was furnished by the Hamilton County Commissioners. The Hamilton County Park district has undertaken the develop- ment and management of recreation facilities in the reservoir area for use of the public in accordance with license granted by the Secretary of the Army on October 31, 1951. Operations and results during fiscal year. Work in connection with the acquisition of lands was continued. Routine operations and maintenance were performed during the year.

Massillon, Ohio, is located in Stark County, on the Tuscarawas River, 200 miles above the mouth of the Muskingum River. Existing project. The project providing for improvement of the channel of the Tuscarawas River, together with the construc- tion of drainage facilities, levees, and pump stations, consists of the following features: 12,800 linear feet of channel rectification and improvements; 4,300 feet of new channel; two reinforced concrete pressure conduits with a total length of 4,300 feet; 15,900 feet of earth levee; 200 feet of concrete wall; four pump stations; and three gate openings. The project necessitated the relocation of 6 miles of railroad; the construction of five railroad bridges, railroad terminal facilities, one highway bridge, and two highway viaducts; the removal of three railroad bridges, one highway bridge, and 10,550 feet of railroad track; and the raising of one highway bridge. The project provides protection (with 3-foot freeboard) against a flood with peak discharge 20 percent greater than maximum of record. The existing project was selected for construction under the general authorization for the Ohio River Basin, contained in the Flood Control Act approved June 28, 1938. The project was constructed at a total Federal cost of $8,139,406. The average annual maintenance cost during the past 5 years was $4,500. Local Cooperation. None required by Law, however, the Massil- lon Conservancy District, a corporation and political subdivision of the State of Ohio, acting for the city of Massillon, Ohio, con- tributed $477,813 for the construction of two pressure conduits, two viaducts over the Tuscarawas River, and furnished rights-of- way required for the improvements outside the scope of the authorized project. On June 4, 1940, the Massillon Conservancy District furnished assurance that it would maintain and operate, after completion, without cost to the United States, all pump stations and maintain all grade elimination structures according to law. The Massillon Conservancy District's obligations, relative to the operation and maintenance of the project, were delegated to and accepted by the city of Massillon.

MUSKINGUM RIVER RESERVOIRS, OHIO Location. The Muskingum River lies in southeastern Ohio and, with its tributaries, drains approximately 8,000 square miles. Its headwaters rise about 25 miles south of Lake Erie and it flows into the Ohio River at Marietta, Ohio, 172.2 miles below Pittsburgh, Pa. Existing project. This project provides for the construction, operation, and maintenance of 14 reservoirs and appurtenant works in the Muskingum River Basin. It was originally author- ized by the Public Works Administration February 20, 1934, to include 15 reservoirs as set forth in an official plan prepared by the Corps of Engineers and adopted by the Muskingum watershed conservancy district of Ohio, the sponsoring agency. Subsequent amendments to the official plan provided, among other things, for the elimination of one reservoir and the inclusion and later elimi- nation of a project for channel improvement of the Tuscarawas River at Massillon, Ohio. Allotments totaling $27,190,000 were made from December 1933 to July 1937 by the Public Works Ad- ministration to aid in financing construction of this project. The project was operated and maintained by the conservancy district from July 1938 to August 1939 when it was taken over by the Corps of Engineers for maintenance and operation in accordance with the provisions of the Flood Control Act approved August 11, 1939. FLOOD CONTROL-HUNTINGTON, W. VA., DISTRICT 1053 The Flood Control Act approved June 28, 1938, authorized and directed the Secretary of War to reimburse the conservancy dis- trict a sum not to exceed the actual expenditures made by it in acquiring lands, easements, and rights-of-way for reservoirs in the Muskingum River Valley, such reimbursements not to exceed $4,500,000, nor include an expenditures for lands, easements, and rights-of-way heretofore or hereafter purchased from said district by the United States. The first allotment under this authorization was made June 29, 1939, from the War Department Appropriation Act of June 28, 1939. The Flood Control Act approved August 11, 1939, contained the provisions that the Muskingum River reservoirs be included in the flood-control plan for the Ohio River Basin authorized in the Flood Control Act approved June 28, 1938; that section 2 of the latter act apply to those reservoirs; and that the conservancy district be relieved of any obligation to maintain and operate the dams. The Flood Control Act approved July 24, 1946, authorized such channel rectification works or other measures at or below the Muskingum River reservoirs as in the discretion of the Chief of Engineers and the Secretary of War may be found necessary to provide for the most efficient operation of those reservoirs, at an estimated cost of $2,200,000. The estimate of Federal cost for new work (1957), is $40,800,- 000 of which $18,281,900 is for construction, and $22,518,100 is for lands and damages. The average annual maintenance cost during the past five years was $213,100. The table on the following page gives the principal features of the 14 reservoirs. Local Cooperation. Fully complied with. For details, see Annual Report for 1942, page 1257. Operations and results during fiscal year. New work: Work in connection with the acquisition of land continued. Payment of an agreed amount of $525,062 was made to the Muskingum Watershed Conservancy District, as complete and final payment of reimbursements authorized by the Flood Control Act of 1939. Operation and maintenance, general. The reservoirs were operated for the benefit of flood control, as required, and neces- sary repairs were made to the dams and their appurtenances and to the operators' quarters and grounds. General moderate rains on April 1 to 5 inclusive and April 7 and 8, 1957 caused a rise in the reservoirs during which 273,700 acre-feet of water was stored. The Muskingum River crested at Coshocton at 10.2 feet; Dresden at 16.9 feet; Zanesville at 22.0 feet and McConnelsville at 9.8 feet. The reductions effected by the reservoirs were 7.0 feet at Coshocton; 7.6 feet at Dresden; 5.5 feet at Zanesville and 3.7 feet at McConnelsville. Minor floods at Coshocton, Dresden, and McConnelsville were averted. The total cost during the fiscal year was $766,310 of which $537,783 was for new work and $228,527 was for maintenance.

INSPECTION OF COMPLETED FLOOD-CONTROL WORKS The Flood Control Act approved June 22, 1936, and subsequent acts require local interests to furnish assurances that they will maintain and operate certain local protection projects after com- pletion in accordance with regulations prescribed by the Secretary of the Army. District Engineers are responsible for the admin- istration of these regulations within the boundaries of their re- spective district. The average annual cost of this work in the Huntington District during the past 5 years was $3,600. Maintenance inspections were made during the fiscal year of completed units of projects transferred to local interests for main- tenance and operation. Local interests were advised, as neces- sary, of measures required to maintain these projects in accordance with standards prescribed by the regulations. The cost during the year was $2,947 for maintenance. The cost to the end of the fiscal year was $24,094 for maintenance.

How- ever, inclusion of a more comprehensive project in the pending Omnibus R and H Bill eliminates con- sideration under PL 685. The projects studies at Grundy, Pound, and Haysi indicated the infeasibility of constructing improvements within monetary limitations of the Act. Plans and Specifications for construction at Prestonsburg and Olive Hill were initiated. Costs incurred during the fiscal year were $20,705. Total costs to the end of the fiscal year were $20,705. Emergency flood-control activities--repairs and flood fighting and rescue work (Public Law 99, 84th Cong., 1st sess., and ante- cedent legislation). Work during the year consisted of revision of the District's flood emergency plan, assistance to communities and compilation of data during the floods of January 27, to February 1, 1957 in the Big Sandy and Guyandot River Basins, and initiation of a post-flood report thereon. The total costs incurred during the fiscal year were $23,936. The total costs to the end of the fiscal year were $154,808.

An allotment for fiscal year 1958 of $54,500, plus an unexpended balance of $12,832 will be applied to four flood-control survey reports, and a basin-wide Ohio River Review. The additional sum of $46,200 can be profitably expended during fiscal year 1959 in accomplishing work under this heading. 23. RESEARCH AND DEVELOPMENT Hydrologic studies were accomplished during this fiscal year at a cost of $217. An unexpended balance of $383 will be profitably expended during fiscal year 1958 in completing work in progress under this heading.

This river rises in northern Pennsylvania, flows northwestward into New York, thence generally southwestward to Pittsburgh, Pa., where it joins with the Monongahela River to form the Ohio. Its length is 325 miles. (See U. S. Geological Survey charts for western Pennsylvania and southwestern New York.) Existing project. This provides for eight locks and dams to afford slack water navigation from Pittsburgh, Pa., to above East Brady, Pa., a distance of 72 miles. Original locks and dams 2 and 3 were replaced by new locks and dams 2 and 3 in 1934. Lock and dam 1 was eliminated in 1938 by the raising of the Emsworth Dam, Ohio River. The controlling depth throughout the canalized por- tion is 9 feet at normal pool level, and the channel width varies from a minimum of 200 feet to full width of river at the mouth. 1077 1078 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The cost of new work for the completed project is $18,157,860. The average annual maintenance cost during the past 5 years was $324,000.

Local cooperation. Fully complied with. Terminal facilities. The city of Pittsburgh has constructed a modern wharf for river freight. There are numerous privately maintained terminals and docks, consisting of tipples, various types of hoists, chutes, and pipelines for use in loading and unload- ing coal, coke, sand, gravel, limestone, cement, petroleum products, steel products, and other commodities. The trans-shipment of freight between river and railroads is handled at privately owned river-to-river terminals. Operations and results during the fiscal year. Operation and maintenance, general: Routine investigations and inspections were performed by hired labor. Snagging operations were performed as required to maintain the navigation channel. The locks and dams were operated as required and necessary repairs and improvements made thereto and to the appurtenant structures to maintain them in a serviceable condition. In addi- tion thereto, the following major rehabilitation work was per- formed by hired labor: at lock 2, the filling and emptying valves were repaired; at locks 4 to 7, inclusive, the lock walls were spot- repaired with gunite; at lock 8, the gratings over the recesses were regalvanized; and at locks 2 to 9, inclusive, dredging of lock chambers and approaches was accomplished. The costs were $322,750, all for operation and care of locks and dams. Condition at end of fiscal year. The existing project is com- plete, the last lock being placed in service in 1938. All locks and dams are in good condition. The navigation channel has been widened at certain points and, in general, maintained to project depth, thus affording adequate depth for passage of commercial tows.

TYGART RIVER DAM, W. VA. Location. The dam site is located on the Tygart River in Taylor County, W. Va., about 22.7 miles above the mouth of the river at Fairmont, W. Va. It is 2.25 miles upstream from Grafton, W. Va., and about 78 miles south of Pittsburgh, Pa. The reser- voir is located in Taylor and Barbour Counties, W. Va. (See U. S. Geological Survey charts for Fairmont, Thornton, and Belington, W. Va.) Existing project. The construction of a concrete gravity dam was authorized by the Public Works Administration January 11, 1934, and adopted by the River and Harbor Act approved August 30, 1935. This dam is 1,921 feet in length at the top and rises 207 feet above the river bed at the uncontrolled center spillway section, which is flanked by abutment sections 23 feet higher. The struc- ture provides for the gross controlled storage of 289,600 acre-feet of water from a tributary drainage area of 1,183 square miles. Approximately 278,400 acre-feet of this controlled storage are available for flood prevention in the Monongahela and Ohio Valleys, while the remaining 11,200 acre-feet are permanent storage. Low water control is also provided by storing 100,000 acre-feet during the spring months for release during low rainfall periods to make up the deficiency of water in the Monongahela RIVERS AND HARBORS-PITTSBURGH, PA., DISTRICT 1081 River. Two penstocks are contained in the dam for possible future generation of hydroelectric power. The cost of new work for the completed project is $18,431,844. The average annual maintenance cost during the past 5 years was $35,500. Operations and results during the fiscal year. Operation and maintenance, general. The reservoir was operated effectively, as required, and necessary repairs were made to the dam and its appurtenances and to the operators' quarters and grounds. In addition, thereto, the needle valves and the sluice gate follower legs were repaired by hired labor. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th caused appreciable flooding along the Monongahela River during the 6th-7th between lock 6 (lower) and lock 2 (lower). The Ohio River crested at Pittsburgh at 24.87 feet on the 6th and at Wheeling, W. Va. (lock 12) at 34.75 feet on the 7th. This was the highest summer rise since July 1896 along the upper Ohio River Valley. The reduction made by this reser- voir at both Pittsburgh and Wheeling was 0.25 foot and in com- bination with the other seven reservoirs above Pittsburgh was 2.8 feet, and in combination with the other nine reservoirs above Wheeling was 3.0 feet. The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatest natural summer flood since August 1888. The Monongahela River at locks 15 and 5 crested at 15.9 and 29.0 feet while the reductions were 2.5 feet and 0.7 foot, respectively. The water stored during this flood caused the reservoir to rise to elevation 1136.0 on the 8th or 42.0 feet above summer pool (1094.0). This level, the highest reached during the year, represents an impoundment of 87,000 acre-feet above summer pool (111,200 acre-feet), or about 49 percent of the usable capacity of the reservoir. Water stored in the reservoir also averted flooding for one-half day along the upper Monongahela River and reduced the period of flooding by one-half day along the lower Monongahela River. Minor direct flood- control benefits were achieved by this reservoir along the upper Ohio River valley between Pittsburgh and Wheeling and along the Monongahela River and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to Mile 25.4, Ohio River), $115,200; Wheeling Damage Dis- trict (Mile 25.4 to Mile 109, Ohio River), $50,900; Monongahela River from Fairmont, W. Va. to lock 2, $55,200. 'of Heavy rainfall over the Monongahela River basin from the afternoon of December 13 until the afternoon the December 14, 1956, following 2 days of intermittent light to moderate rainfall, caused a minor flood during the 14th-15th along a reach between lock 6 (lower) and lock 2 (upper). The Monongahela River at locks 15 and 5 crested at 16.7 and 24.0 feet while the reductions were 2.1 and 1.4 feet, respectively. The water stored during this flood caused the reservoir to rise to elevation 1091.9 on the 16th or 81.9 feet above winter pool, representing an impoundment of 96,400 acre-feet above minimum pool, or about 35 percent of the 1082 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 usable winter flood control capacity of the reservoir. Water stored in the reservoir averted minor flooding for one-half day between lock 7 and lock 15. Along the lower Monongahela River valley the period of flooding was reduced by one-half day. Along the entire river suspension of navigation was reduced by one-half day. Minor direct flood control benefits were achieved by this reservoir along the entire course of the Monongahela River from Fairmont, W. Va. and lock 2 and were estimated at $42,800. Heavy rainfall from late on January 9, 1957 until early on the 10th over the Monongahela River basin accompanied by a moderate thaw caused a moderate rise in the reservoir during which 57,600 acre-feet of water was stored. The Monongahela River at locks 15 and 5 crested at 13.5 and 21.5 feet, while the reductions were 2.35 and 1.6 feet, respectively. Along the lower Monongahela River flood stage and attendant minor flooding was averted for one-half day. Along the upper Monongahela River suspension to navigation was averted for one day, while along the lower river suspension to navigation was reduced by one-half day. Very minor direct flood control benefits were achieved along the lower Monongahela River and were estimated at $300. Water stored in the reservoir during this rise in conjunction with storage in Youghiogheny, Conemaugh, and Loyalhanna Reservoirs prevented the Ohio River at Pittsburgh from exceeding pool limit. Heavy rainfall from the afternoon of January 22, 1957 until morning of the 23d caused a moderate rise in the reservoir during which 42,700 acre-feet of water was stored. Along the lower Monongahela River suspension to navigation was averted for one day. Heavy rainfall during January 28-29, 1957 accompanied by light snow melt caused a major rise in the reservoir during which 80,100 acre-feet of water were stored. Along the unper Monon- gahela River suspension to navigation was averted for 11/ days, while along the lower river suspension to navigation was reduced by 11/9 days. The reduction made by this reservoir in combination with Youghiogheny Reservoir at lock 2 was 2.1 feet, just averting flood stage. During the rise, water stored in conjunction with storage in Youghiogheny Reservoir also prevented the Ohio River at Pittsburgh from exceeding pool limit. Heavy rainfall over the Monongahela River basin on February 1, 1957 caused a moderate rise into the reservoir during which 18,000 acre-feet of water were stored. Along the lower Monon- gahela River suspension to navigation was averted for one-half day. Heavy rainfall again over the Monongahela River basin from early on February 9, 1957 until early on the 10th caused a minor flood during the 10th-llth along a reach between lock 6 (lower) and lock 2 (upper). The Monongahela River at locks 15 and 5 crested at 15.0 and 25.2 feet, respectively, while the reduction was 4.5 feet at both locks. The water stored during the flood caused the reservoir to rise to elevation 1115.8 on the 12th or 105.8 feet above winter pool, representing an impoundment of 141,500 acre- feet above minimum pool, or about 51 percent of the usable winter RIVERS AND HARBORS-PITTSBURGH, PA., DISTRICT 1083 flood control capacity of the reservoir. This was both the maxi- mum amount and percent of flood control storage used for the year. Water stored in the reservoir averted minor flooding for one day between lock 7 and lock 15, and reduced the period of flooding along the lower Monongahela River valley by one-half day. Along the upper Monongahela River suspension to naviga- tion was reduced by 11/2 days, while along the lower river sus- pension to navigation was reduced by one-half day. Major direct flood-control benefits were achieved by this reservoir along the entire course of the Monongahela River from Fairmont, W. Va. to lock 2 and were estimated at $546,100. During October 17-25, 1956 the outflow was regulated to ac- commodate critical repair work at lock 15, Monongahela River while more than satisfying the navigation flow requirements for the river. During the remainder of the year routine operations were made in accordance with the storage schedule, except on the occasion of 14 minor rises when some water was stored and released as river conditions permitted. Some reservoir management activity was continued throughout the year comprising sanitation measures, conservation, land management, and operation and maintenance of public-use facil- ities. This work was limited in scope as the State of West Virginia has jurisdiction over recreation in the reservoir area. The costs were $38,865, all for operation and maintenance. Condition at end of fiscal year. The authorized project is complete. The reservoir is in operation for low water control in the Monongahela River and for the purpose of flood protection in the Monongahela and Ohio Valleys. Construction of the dam was started in 1935 and placed in operation in 1938.

S. ARMY, 1957 3. MONONGAHELA RIVER, PA. AND W. VA. Location. This river is formed by the junction of the Tygart and West Fork Rivers about 1 mile south of Fairmont, W. Va., and flows in a northerly direction 128 miles to its junction with the Allegheny River, forming the Ohio River at Pittsburgh, Pa. (See U. S. Geological Survey charts for southwestern Pennsylvania and northern West Virginia.) Previous projects. These provided for acquisition by the United States in 1897 of original locks 1 to 7, inclusive, which were built by the Monongahela Navigation Co., and the extension of slack water navigation to the head of the river by the construction of original locks 8 to 15, inclusive, prior to 1904. The projects were adopted by the River and Harbor Acts of June 10, 1872, June 3, 1896, and June 4, 1897. For further details see page 1910 of Annual Report for 1915, and page 1248, Annual Report for 1938. Existing project. This provides for the improvement of the river by 12 locks and dams to afford slack water navigation for its entire length from Pittsburgh, Pa., to above Fairmont, W. Va. Original locks and dams 7, 8, and 9 were replaced by new locks and dams 7 and 8 in 1925. Increased traffic necessitated an enlargement and improvement of locks and dams 1 to 6 between Pittsburgh and Rices Landing, Pa., by the building of two parallel chambers and fixed concrete dams. Locks and dam 1 were eliminated in 1938 by the raising of the Emsworth Dam, Ohio River. Recon- struction of lock 2 provides for two modernized navigation locks, one 110 by 720 feet and one 56 by 360 feet. Locks and dams 5 and 6 are inadequate for the present traffic and are nearing the end of their economic life and should be replaced. Original locks and dams 10 to 15, inclusive, are inadequate for the present traffic and should be replaced as soon as practicable. Construction of Morgantown lock and dam was the initial step in the replacement program and replaced locks and dams 10 and 11. Hildebrand and Opekiska locks and dams will replace locks 12 to 15, inclusive. Alterations to dam 8 will raise pool 8 by 4 feet. Completion of these improvements from dam 8 upstream will pro- vide for the entire river length a minimum channel depth of 9 feet, varying in width from a minimum of 300 feet to practically full width at the mouth. The estimate of cost for new work (1957) (exclusive of amounts expended on previous projects) is $133,315,000. The average annual maintenance cost during the past 5 years was $1,267,500. Terminal facilities. The city of Pittsburgh has constructed a modern wharf for river freight. Boat landings are maintained by some municipalities along the river. A large number of tipples at mines and various types of hoists at manufacturing plants and sand and gravel supply companies are maintained for private use in loading and unloading coal, coke, billets, steel products, sand, gravel, and other commodities. These terminals and docks are not available for the purpose of general commerce.

May 17, 1950 Modification of the existing project as follows: Senate Doc. 100, 81st Cong., 1st Provide for 2 new locks and dams similar to the sess. Morgantown lock and dam to replace existing locks and dams 12 to 15, inclusive. Provide for a movable crest on existing dam 8 to raise the existing pool-full elevation 4 feet. Provide for a navigation channel of 300-foot mini- mum bottom width and a 9-foot project depth above lock and dam 8. Provide for an extension of the navigable channel of the upper Monongahela River, into the lower Tygart River for a distance of 2.1 miles at a maximum bottom width of 200 feet and a 9-foot project depth. 1Public Res. 117, 71st Cong., 3d sess. 2 Permanent Appropriations Repeal Act. A number of docks and pipelines are also privately maintained for petroleum and acid products. Marine ways are maintained by some of the larger industries. There are also several ter- minals for rail-to-river and river-to-rail transfer. Existing private terminals are adequate for shipments and receipt in the Pittsburgh district of the type of commerce now in existence. The provision of river-to-rail and rail-to-river trans- fer terminals on an extensive scale is not important, since 98 percent of traffic using the river passes through the private terminals which are more than adequate for the prospective commerce.

(Raise Crest): Plans, specifications and analysis of design for alterations to the existing dam and river lock wall were completed by architect-engineer contract and are under final review. Plans for anchoring the river wall and miter gate sills are being pre- pared by hired labor. This work will be incorporated with that of the architect-engineer and all advertised under one construction contract. Hildebrand lock and dam: Construction of the locks and dam was continued under continuing contract. Excavation for the lock structure was completed except for the lower guide wall re- sulting in the removal of approximately 476,000 cubic yards of material. The placing of concrete in the lock commenced in mid- March resulting in seven monoliths being topped out on the river wall, all but two monoliths being completed on the upper guide wall and all but four monoliths on the upper guard wall. A total of 36,600 cubic yards of concrete were placed in these operations. Operation and maintenance, general: The locks and dams were operated as required and necessary repairs were made thereto and to the appurtenant structures to maintain them in a serviceable condition. A preliminary design memorandum on reconstruction of locks and dams on the middle Monongahela River was completed. In addition to ordinary repairs to structures and plant, the following major rehabilitation work was performed by hired labor except where noted: at lock 2, installation of connec- tions for lifting the land chamber gates was completed; at lock 4, the upper and lower gates, land chamber, were replaced with previously repaired spare gates; at lock 5, repairs were made to the turbines, the piping in the crossover and the lower river wall emp- tying valve; at lock 6, replacement was made of the lower land chamber gates, upper river chamber gates and repairs made to the valves, sills, gates, operating machinery, and turbine of both chambers; at lock 7, replacement was made to the lower gates, and repairs initiated to the valves, sills, walls, and operating ma- chinery; at lock 8, the lock chamber walls, guide walls, and river face of river wall were refaced and the top of walls repaired; miter sills were drilled and the core holes capped by contract; the lower approach to lock 3 was dredged by contract; work was initiated for the removal of a bar at Mile 21.1-21.6 and at locks 2 to 15, inclu- sive, lock chambers and approaches were dredged where required and snags removed from the channel. The costs were $4,733,520 of which $3,318,272 was for new work, and $1,415,248 for operation and care of locks and dams. Condition at end of fiscal year. The locks and dams are in operation and are complete except for replacement of locks 5 and 6, by construction of Maxwell locks and dam and supplemented by raising of dam 4, raising the crest of dam 8, and replacement of locks 12 to 15, inclusive, by construction of Hildebrand lock and dam and Opekiska lock and dam. A controlling depth of 9 feet in the navigation channel is maintained from Pittsburgh to the upper reaches of pool 8 which has a controlling depth of approximately 7 feet. The recent construction of Morgantown lock and dam 1088 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 provides for a 9-foot channel from Morgantown dam to lock and dam 12. Upon completion of improvements at dam 8, and con- struction of Hildebrand lock and dam and Opekiska lock and dam, a minimum channel depth of 9 feet will exist for the entire length of the river, varying in width from a minimum of 300 feet to full width of the river at the mouth. Reconstruction of the 56-foot lock (river chamber) at lock 2 was commenced by contract January 7, 1949, and was accepted as complete June 29, 1951. Construction of the 110-foot lock (land chamber) was initiated by contract June 26, 1951, and was completed November 29, 1953. Construction of Morgantown lock and dam was started by contract September 9, 1948, and accepted as complete December 22, 1950. All miscellaneous appurtenances pertaining to the new lock are complete. Relocation and land acquisition are complete. No work has been performed in connection with the proposed re- placement of locks and dams 5 and 6. In connection with the proposed improvements at dam 8, plans, specifications and analysis of design have been completed and are under final review. Con- struction of Hildebrand lock and dam was initiated by contract April 29, 1956, and is approximately 34 percent complete to date. Work remaining for completion of the project consists of the following: Replacement of locks 5 and 6; raising the crest of dam 8; construction of Hildebrand lock and dam which will re- place existing locks and dams 12 and 13; and construction of Opekiska lock and dam to replace existing locks and dams 14 and 15.

The dam site is located on the Allegheny River in the vicinity of Kinzua, Warren County, Pa., approximately 200 miles above the mouth of the river at Pittsburgh, Pa. The reser- voir is located in Warren and McKean Counties, Pa. and, Cat- taraugus County, N. Y. (See U. S. Geological Survey charts for Warren and Kinzua, Pa.-N. Y., and Randolph and Salamanca, N. Y.) Existing project. This provides for the construction of a reservoir dam for flood control, pollution abatment and related purposes. The dam will be of the concrete gravity type with a gate-controlled center spillway and discharge conduits controlled by slide-gates and will provide for a gross storage of approximately 1,125,000 acre-feet of water from a tributary drainage area of 2,190 square miles. Of this storage, approximately 1,105,000 acre-feet will be available for flood control and flow regulation. The remaining 20,000 acre-feet would be in permanent storage. The reservoir will be operated as required for flood-control pur- poses as a unit of a reservoir system for the protection of the Allegheny Valley, Pittsburgh and the upper Ohio Valley, generally, and for low flow regulation in the interest of industrial and domestic water supply, pollution abatement and navigation in the Allegheny and Ohio River Valleys. The existing project was authorized by the Flood Control Acts approved June 22, 1936, June 28, 1938, and August 18, 1941. The estimated cost for new work (1957) is $101,000,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operationsand results during fiscal year. New work: Advance planning continued throughout the year and consisted of com- pletion of the hydrology design memorandum and the site selection memorandum.

TIONESTA RESERVOIR, OHIO RIVER BASIN, PA. Location. The dam site is located on Tionesta Creek, 1.25 miles above the junction of the creek with the Allegheny River at Tionesta, Pa., and about 78 miles northeast of Pittsburgh, Pa. The reservoir is located entirely in Forest County, Pa. (See U. S. Geological Survey charts for Tionesta, Tidioute, and Sheffield, Pa.) Existing project. This provides for the construction of a flood-control reservoir dam of the earthfill type with separate uncontrolled saddle spillway and tunnel outlet works. The dam is 1,050 feet long at the top, rises 154 feet above the streambed, and provides for the gross storage of 133,400 acre-feet of water from a tributary drainage area of 478 square miles. Of this storage 125,600 acre-feet are available for flood prevention at Pittsburgh and in the upper Ohio Valley, generally. The re- maining 7,800 acre-feet are in permanent storage. The reser- voir is operated as a unit of a coordinated reservoir system for the protection of Pittsburgh and the upper Ohio Valley gener- ally. The existing project was authorized by the Flood Control Acts approved June 22, 1936, and June 28, 1938. The estimated cost for new work (1957) is $5,324,000. The average annual maintenance cost during the past 5 years was $47,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operationsand results during fiscal year. Operation and main- tenance, general: The reservoir was operated for the benefit of flood control, as required, and necessary repairs were made to the dam and its appurtenances and to the operator's quarters and grounds. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th caused a minor rise in the Allegheny FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1(093 and Ohio Rivers. The Ohio River crested at Pittsburgh at 24.87 feet on the 6th and at Wheeling, W. Va. (lock 12) at 34.75 feet on the 7th. This was the highest summer rise since July 1896 along the upper Ohio River valley. The reduction made by this reser- voir at both Pittsburgh and Wheeling was 0.15 foot and in com- bination with the other seven reservoirs above Pittsburgh was 2.8 feet, and in combination with the other nine reservoirs above Wheeling was 3.0 feet. The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatest natural summer flood since August 1888. The water stored caused the reservoir to rise to elevation 1103.7 on the 8th or 18.7 feet above minimum pool. This represented an impoundment of 12,400 acre- feet above minimum pool, or about 10 percent of the usable flood- control capacity of the reservoir. Minor direct flood-control benefits were achieved by this reservoir along the upper Ohio River valley between Pittsburgh and Wheeling and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to mile 25.4, Ohio River), $70,500; Wheeling Damage District (mile 25.4 to mile 109, Ohio River), $30,300. Heavy rainfall over the Allegheny River basin from the after- noon of January 22, 1957 until morning of the 23d accompanied by a rapid thaw during the 22d of a heavy snow cover over the upper Allegheny River basin above Franklin, Pa. caused a flood along the Allegheny River from lock 7 (upper) to lock 8 (lower). The Allegheny River at Franklin crested at 16.0 feet on the 23d, while the reduction was 1.0 feet, just averting flood stage. The Allegheny River at locks 7 and 4 crested at 20.7 and 18.8 feet, re- spectively, on the 24th. The reduction made at lock 7 was 0.65 foot and in combination with Mahoning Reservoir was 1.05 feet, reducing both the period of flooding and the period of suspension to navigation by one day. The reduction made by this reservoir at lock 4 in combination with Mahoning, Crooked Creek, Loyal- hanna, and Conemaugh Reservoirs was 2.5 feet, averting suspen- sion of navigation for one day. The water stored during the flood caused the reservoir to rise to elevation 1117.9 on the 25th or 32.9 feet above minimum pool. This represented an impound- ment of 26,700 acre-feet above minimum pool, or about 21 percent of the usable flood-control capacity of the reservoir. Minor direct flood-control benefits were achieved by the reservoir along Alle- gheny River in the Kittanning Damage District (mile 30.4 to mile 46.0, Allegheny River) and were estimated at $19,500. Intermittent, mixed heavy precipitation during April 3-8, 1957 over the basin caused a major rise in the reservoir which resulted in the reservoir reaching the highest level during the year, eleva- tion 1122.8 on the 9th or 37.8 feet above minimum pool. This represented an impoundment of 32,600 acre-feet above that pool or about 26 percent of the usable capacity of the reservoir. The reservoir pool was drawn down below minimum pool during September 23-29 for an investigation by the district geologist of the grading for a boat-launching ramp. During the remainder 1094 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of the year routine operations were made except on the occasion of 19 minor rises when some water was stored and released as river conditions permitted. Activities under the reservoir management program compris- ing sanitation measures, conservation, land management, and operation and maintenance of public use facilities were continued. Construction of a public access road to the reservoir was continued. The total costs were $45,765, all for operation and maintenance. Condition at end of fiscal year. The dam and its appurte- nances are complete, and the reservoir is in operation as a unit of the reservoir system designed for the protection of Pittsburgh and the reduction of flood heights in the upper Ohio Valley, generally. Construction of the dam was started in May 1938 and completed in January 1941. All work relative to relocations and acquisition of land is complete. The total acreage involved has been acquired and consists of 3,040 acres in fee simple and flow- age easements over 349 acres. A master land use plan is com- plete. Remaining work consists of provision on project lands of additional recreational facilities required to serve the public needs.

Location. The dam site is located in Elk County, Pa., on the East Branch of the Clarion River above Middle Fork, approxi- mately 7 miles above the junction of the East and West Branches of the Clarion River at Johnsonburg, Pa., and approximately 151 miles northeast of Pittsburgh, Pa. The reservoir is located entirely in Elk County, Pa. (See U. S. Geological Survey chart for Mount Jewett, Pa.) FLOOD CONTROL--PITTSBURGH, PA., DISTRICT 1095 Existing project. This provides for the construction of a reservoir dam of the rolled-earthfill type with gate-controlled con- crete tunnel under right abutment and a paved uncontrolled spill- way on the left abutment slope. The dam, 1,725 feet long at the top and rising 184 feet above the streambed, will provide for the gross controlled storage of 84,300 acre-feet, from a tributary drainage area of 72.5 square miles. Of the total storage, 83,300 acre-feet will be available for flood control and low water regula- tion purposes, in the Clarion River Valley below. The remaining 1,000 acre-feet will be in permanent storage. The reservoir will be operated as a unit of a coordinated reservoir system for the pro- tection of Pittsburgh and the upper Ohio Valley, generally. The project was selected for construction under the general authoriza- tion for the Ohio River Basin contained in the Flood Control Acts approved June 28, 1938, and December 22, 1944. The estimate of cost for new work (1956) is $9,163,000. The average annual maintenance cost during the past 5 years was $27,500. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. New work: Investi- gations were underway to determine the extent of remedial work required. Operation and maintenance, general: The reservoir was oper- ated for the benefit of flood control, as required, and necessary repairs made to the dam and its appurtenances and to the opera- tor's quarters and grounds. Intermittent, heavy thundershowers from late on August 4, 1956 until noon on the 7th caused a triple peak, moderate rise in the upper Clarion River. The Clarion River crested on the 6th at Johnsonburg at 5.44 feet and on the 7th at Ridgway at 5.86 feet. The reductions made by this reservoir at Johnsonburg and Ridg- way were 1.15 and 1.25 feet, respectively, averting light flooding along the upper Clarion River for one day. Minor direct flood- control benefits were achieved along the upper Clarion River valley and were estimated as follows: Johnsonburg Damage District, $6,000; Ridgway Damage District, $3,900. The water stored caused the reservoir to rise to elevation 1663.6 on the 9th or 6.9 feet above the normal drawdown pool level on that date. This represented an impoundment of 7,200 acre-feet above schedule or about 22 percent of the usable flood-control storage capacity of the reservoir for that date. This rise resulted in the use of the maximum amount and percent of flood-control storage for the year. On December 2, 1956 the reservoir had fallen to elevation 1624.1, the lowest elevation for the 1956 low water season. During the following six months there was sufficient precipitation and runoff to amply replenish the low water storage while complying with the flow-temperature schedule at Johnsonburg. The outflow was in- creased in January during four periods to break up critical ice conditions and improve the flow along the upper Clarion River during periods of near or subzero weather in the basin; 2nd-4th, 6th-7th, llth-12th and 13th-16th. During the remainder of the year until mid-May routine operations were made in accordance 1096 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 with the low water schedule for maintaining satisfactory flows in the upper Clarion River, except on the occasion of 13 minor rises when water was stored, with the excess above normal schedule storage being released as river conditions permitted. Intermittent moderate rainfall during April 24-26, 1957 produced a series of minor rises which resulted in the reservoir reaching the highest level during the year, elevation 1671.3 on the 28th or 1.3 feet above summer pool. This represented an impoundment of 1,500 acre- feet above summer pool or about 8 percent of the usable summer flood-control storage capacity of the reservoir. From the 2d week in May until the final week in June the reser- voir was lowered to elevation 1570.7 feet, m.s.l., for investigation and repair work. Activities under the reservoir management program comprising sanitation measures, conservation, land management and opera- tion and maintenance of public-use facilities were continued. The Federal Power Commission in Determination of Proportion of Annual Charges for Headwater Benefits, Document No. E-6759 issued July 6, 1956, stated therein that the Piney hydroelectric development of the Pennsylvania Electric Co. benefited directly from the initial operation of the project in the amount of $12,864 covering the 3-year period from November 1, 1952 through October 31, 1955.

The dam site is located on Mahoning Creek in Arm- strong County, Pa., 21.6 miles above the junction of the creek with the Allegheny River. It is about 61/2 miles southeast of New Bethlehem, Pa.; and about 51 miles northeast of Pittsburgh, Pa. The reservoir is located in Armstrong, Indiana, and Jefferson Counties, Pa. (See U. S. Geological Survey charts for Rural Valley and Smicksburg, Pa.) Existing project. This provides for the construction of a flood-control reservoir dam of the concrete gravity type with a gate-controlled center spillway flanked by abutment sections join- ing the valley sides. The dam is 926 feet long at the top, rises 162 feet above the streambed, and provides for the gross controlled storage of 74,200 acre-feet of water from a tributary drainage area of 339 square miles. Of this storage 69,700 acre-feet are available for flood prevention at Pittsburgh and in the upper Ohio Valley, generally. The remaining 4,500 acre-feet are in per- manent storage. Two penstocks are contained in the structure for possible future generation of hydroelectric power. The reser- voir is operated as a unit of a coordinated reservoir system for the protection of Pittsburgh and the upper Ohio Valley, generally. The existing project was authorized by the Flood Control Acts ap- proved June 22, 1936, and June 28, 1938. The cost of the com- pleted project is $6,421,345. The average annual maintenance cost during the past 5 years was $29,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operationsand results during fiscal year. Operation and main- tenance, general: The reservoir was operated for flood control, as required, and necessary repairs made to the structure and to the operators' quarters and grounds throughout the year. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th caused a minor rise in the Allegheny and Ohio Rivers. The Ohio River crested at Pittsburgh at 24.87 feet on the 6th and at Wheeling, W. Va. (lock 12) at 34.75 feet on the 7th. This was the highest summer rise since July 1896 along the upper Ohio River Valley. The reduction made by this reservoir at both Pittsburgh and Wheeling was 0.2 foot and in combination FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1101 with the other seven reservoirs above Pittsburgh was 2.8 feet, and in combination with the other nine reservoirs above Wheeling was 3.0 feet. The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatestnatural summer flood since August 1888. The water stored during this rise and through subsequent rises from intermittent, heavy thundershowers until early on the 12th caused the reservoir to rise to elevation 1127.5 on the 14th or 52.5 feet above minimum pool. This repre- sented an impoundment of 19,900 acre-feet above minimum pool, or about 29 percent of the usable flood-control capacity of the reservoir. Minor direct flood-control benefits were achieved by this reservoir along the upper Ohio River valley between Pitts- burgh and Wheeling and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to mile 25.4, Ohio River), $92,700; Wheeling Damage District (mile 25.4 to mile 109, Ohio River), $40,600. Heavy rainfall over the Allegheny River basin from the after- noon of January 22, 1957 until morning of the 23d accompanied by a rapid thaw during the 22d of a heavy snow cover over the upper Allegheny River basin above Franklin, Pa. caused a flood along the Allegheny River from lock 7 (upper) to lock 8 (lower). The Allegheny River at locks 7 and 4 crested at 20.7 and 18.8 feet, respectively, on the 24th. The reduction made at lock 7 was 0.4 foot and in combination with Tionesta Reservoir was 1.05 feet, reducing both the period of flooding and the period of suspension to navigation by one day. The reduction made by this reservoir at lock 4 in combination with Tionesta, Crooked Creek, Loyal- hanna, and Conemaugh Reservoirs was 2.5 feet, averting suspen- sion of navigation for one day. The water stored during the flood caused the reservoir to rise to elevation 1122.5 on the 25th or 47.5 feet above minimum pool. This represented an impound- ment of 16.100 acre-feet above minimum pool, or about 23 percent of the usable flood-control capacity of the reservoir. Minor direct flood-control benefits were achieved by this reservoir along the Allegheny River in the Kittanning Damage District (Mile 30.4 to Mile 46.0, Allegheny River) and were estimated at $12.100. Intermittent, mixed heavy precipitation during April 1-8, 1957, over the basin caused a series of minor to maior rises in the reservoir which resulted in the reservoir reaching the highest level during the year, elevation 1143.9 on the 9th or 68.9 feet above minimum pool. This represented an impoundment of 37,500 acre- feet above that pool or about 54 percent of the usable capacity of the reservoir. During the remainder of the year routine opera- tions were made except on the occasion of 22 minor rises when some water was stored and released as river conditions permitted. Activities under the reservoir management program com- prising sanitation measures, conservation, land management, and operation and maintenance of public use facilities were continued. The total costs were $24.767, all for operation and maintenance. Condition at end of fiscal year. The dam and its appurtenances are complete and the reservoir is in operation as a unit of the 1102 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 reservoir system designed for the protection of Pittsburgh and the reduction of flood heights in the upper Ohio Valley generally. Construction of the dam was started in February 1939, and com- pleted in June 1941. All work in connection with relocations and acquisition of land is complete. The total acreage involved has been acquired and consists of 2,533.49 acres in fee simple and flowage easements over 76.89 acres.

CROOKED CREEK RESERVOIR, OHIO RIVER BASIN, PA. Location. The dam site is located on Crooked Creek 6.7 miles above the junction of the creek with the Allegheny River near Ford City, Pa., and about 32 miles northeast of Pittsburgh, Pa. The reservoir is located entirely in Armstrong County, Pa. (See U. S. Geological Survey charts for Freeport and Elders Ridge, Pa.) Existing project. This provides for the construction of a flood- control reservoir dam of the earthfill type with separate uncon- trolled saddle spillway and tunnel outlet works. The dam is 1,480 feet long at the top, rises 143 feet above the streambed, and pro- vides for the gross storage of 93,900 acre-feet of water from a tributary drainage area of 277 square miles. Of this storage 89,400 acre-feet are available for flood prevention at Pittsburgh and in the upper Ohio Valley, generally. The remaining 4,500 acre-feet are in permanent storage. The reservoir is operated as a unit of a coordinated reservoir system for the protection of Pittsburgh and the upper Ohio Valley generally. The existing project was authorized by the Flood Control Acts approved June 22, 1936, and June 28, 1938. The cost of the completed project is $4,204,888. The average annual maintenance cost during the past 5 years was $26,500. FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1103 Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operationsand results during fiscal year. Operation and main- tenance, general: The reservoir was operated for the benefit of flood control, as required, and necessary repairs were made to the dam and its appurtenances and to operators' quarters and grounds. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th caused a minor rise in the Allegheny and Ohio Rivers. The Ohio River crested at Pittsburgh at 24.87 feet on the 6th and at Wheeling, W. Va. (lock 12) at 34.75 feet on the 7th. This was the highest summer rise since July 1896 along the upper Ohio River valley. The reduction made by this reservoir at both Pittsburgh and Wheeling was 0.3 foot and in combination with the other seven reservoirs above Pittsburgh was 2.8 feet, and in combination with the other nine reservoirs above Wheeling was 3.0 feet. The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatest natural summer flood since August 1888. The water stored caused the reservoir to rise to elevation 867.7 on the 7th or 27.7 feet above minimum pool. This represented an impoundment of 16,900 acre-feet above minimum pool, or about 19 percent of the usable flood-control capacity of the reservoir. Moderate direct flood-control benefits were achieved by this reservoir along the upper Ohio River valley between Pittsburgh and Wheeling and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to mile 25.4, Ohio River), $139,800; Wheeling Damage District (mile 25.4 to mile 109, Ohio River), $60,600. Heavy rainfall over the Allegheny River basin from the after- noon of January 22, 1957 until morning of the 23d accompanied by a rapid thaw during the 22d of a heavy snow cover over the upper Allegheny River basin above Franklin, Pa. caused a major rise in the Allegheny River during which 11,900 acre-feet of water was stored in the reservoir. The Allegheny River at lock 4 crested at 18.8 feet on the 24th, while the reduction by this reservoir in com- bination with Tionesta, Mahoning, Loyalhanna and Conemaugh Reservoirs was 2.5 feet, averting suspension of navigation for one day. Intermittent, mixed heavy precipitation during April 1-7, 1957 over the basin caused a major rise in the reservoir which resulted in the reservoir reaching the highest level during the year, eleva- tion 885.7 on the 7th or 24.7 feet above minimum pool. This represented an impoundment of 35,400 acre-feet above that pool or about 40 percent of the usable capacity of the reservoir. Dur- ing the remainder of the year routine operations were made except on the occasion of 15 minor rises when some water was stored and released as river conditions permitted. Activities under the reservoir management program comprising sanitation measures, conservation, land management and opera- tion and maintenance of certain public-use facilities were con- tinued. This work was limited as the Commonwealth of Pennsyl- vania has jurisdiction over recreation in the reservoir area. 1104 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The dam, 1,265 feet long at the top and rising 137 feet above the streambed, will provide for the gross controlled storage of 274,000 acre-feet of water from a tributary drainage area of 1,351 square miles. Of this storage, 270,000 acre-feet will be available for flood-control purposes. The remaining 4,000 acre- feet will be in permanent storage. The reservoir will be operated as a unit of a coordinated reservoir system for the protection of Pittsburgh and the upper Ohio Valley, generally. The existing project was authorized by the Flood Control Acts approved June 22, 1936, and June 28, 1938. The estimated cost for new work (1957) is $45,820,000. The average annual maintenance cost during the past 5 years was $32,000. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. New work: Ac- quisition of land and related work was continued and involved work relative to settlements for land acquired by condemnation. Relocation of sewers in the reservoir area under agreement with owning agencies was completed. Construction of a service road to the left abutment of the dam was completed by contract. Operation and maintenance, general: The reservoir was oper- ated effectively for flood control as required and necessary repairs made to the structure and to the operators' quarters and grounds. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th caused a minor rise in the Allegheny and Ohio Rivers. The Ohio River crested at Pittsburgh at 24.87 feet on the 6th and at Wheeling, W. Va. (lock 12) at 34.75 feet on the 7th. This was the highest summer rise since July 1896 along the upper Ohio River valley. The reduction made by this reservoir at both Pittsburgh and Wheeling was 0.65 foot, and in combination with the other seven reservoirs above Pittsburgh was 2.8 feet, and in combination with the other nine reservoirs above Wheeling was 3.0 feet. The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatest natural summer flood since August 1888. The water stored during this rise and subsequent rise from intermittent, heavy thundershowers until late afternoon on the 7th caused the reservoir to rise to elevation 914.4 on the 8th or 34.4 feet above minimum pool. This represented an impoundment of 28,000 acre-feet above minimum pool, or about 10 percent of the usable flood-control capacity of the reservoir. FLOOD CONTROL--PITTSBURGH, PA., DISTRICT 1107 Major direct flood-control benefits were achieved by this reservoir along the upper Ohio River valley between Pittsburgh and Wheel- ing and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to mile 25.4, Ohio River) $303,000; Wheeling Damage District (mile 25.4 to mile 109, Ohio River) $131,400. Heavy rainfall over the Allegheny River basin from the after- noon of January 22, 1957 until morning of the 23d accompanied by a rapid thaw during the 22d of a heavy snow cover over the upper Allegheny River basin above Franklin, Pa. caused a major rise in the Allegheny River during which 35,000 acre-feet of water was stored in the reservoir. The Allegheny River at lock 4 crested at 18.8 feet on the 24th, while the reduction by this reservoir in combination with Tionesta, Mahoning, Crooked Creek and Loyal- hanna Reservoirs was 2.5 feet, averting suspension of navigation for one day. Intermittent, mixed heavy precipitation during April 1-6, 1957 over the basin caused a series of minor to moderate rises in the reservoir which resulted in the reservoir reaching the highest level during the year, elevation 935.2 on the 7th or 55.2 feet above minimum pool. This represented an impoundment of 78,000 acre- feet above that pool or about 29 percent of the usable capacity of the reservoir. During the remainder of the year routine opera- tions were made except on the occasion of 19 minor rises when some water was stored and released as river conditions permitted. Storage during a minor rise on January 10-11, 1957 in conjunction with storage in Tygart, Youghiogheny and Loyalhanna Reservoirs averted the Ohio River at Pittsburgh from exceeding pool limit. Activities under the reservoir management program comprising sanitation, conservation, land management, and operation and maintenance of public use facilities were continued. The costs during the year were $258,673, of which $227,495 was for new work and $31,178 for operation and maintenance. Condition at end of fiscal year. The dam and its appurtenances are complete and the reservoir is in operation as a unit of the reser- voir system designed for the protection of Pittsburgh and the re- duction of flood heights in the upper Ohio Valley, generally. Con- struction of the dam and appurtenances was started by contract April 25, 1949, and completed December 31, 1952. The furnish- ing and erection of two gantry cranes and 14 crest gates by con- tract were started November 16 and December 9, 1951, and com- pleted August 6 and September 4, 1953, respectively. Relocation of the main line of the Conemaugh Division, Pennsylvania Railroad, was started by contract April 1946 and completed September 19, 1950. Highway and utility relocations are complete. Land acquisition and related work is approximately 98 percent complete. A total of 114 tracts were acquired for the railroad relocation consisting of 1,331 acres in fee and easements over 3 acres.

LOYALHANNA RESERVOIR, OHIO RIVER BASIN, PA. Location. The dam site is located on Loyalhanna Creek, 4.5 miles above the junction of the creek with the Conemaugh River at Saltsburg, Pa., and about 29 miles east of Pittsburgh, Pa. The reservoir is located entirely in Westmoreland County, Pa. (See U. S. Geological Survey chart for Latrobe, Pa.) Existing project. This provides for the construction of a flood- control reservoir dam of the concrete gravity type with a gate controlled center spillway flanked by abutment sections joining the valley sides, and an earth embankment section terminating in the left abutment. The dam, 960 feet long at the top, rises 114 feet above the streambed, and provides for the gross controlled storage of 95,300 acre-feet of water from a tributary drainage area of 290 square miles. Of this storage 93,300 acre-feet are available for flood prevention at Pittsburgh and in the upper Ohio Valley, generally. The remaining 2,000 acre-feet are in permanent storage. One penstock is contained in the structure for possible future generation of hydroelectric power. The reser- voir is operated as a unit of a coordinated reservoir system for the protection of Pittsburgh and the upper Ohio Valley, generally. The existing project was authorized by the Flood Control Acts ap- proved June 22, 1936, and June 28, 1938. The cost of the com- pleted project is $5,452,862.

The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatest natural summer flood since August 1888. The water stored caused the reservoir to rise to elevation 934.8 on the 7th or 24.8 feet above minimum pool. This represented an impoundment of 13,300 acre-feet above minimum pool, or about 14 percent of the usable flood-control capacity of the reservoir. Moderate direct flood-control benefits were achieved by this reservoir along the upper Ohio River valley between Pittsburgh and Wheeling and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to mile 25.4, Ohio River), $186,800; Wheeling Damage District (mile 25.4 to mile 109, Ohio River), $80,600. Heavy rainfall over the Allegheny River basin from the after- noon of January 22, 1957 until morning of the 23d accompanied by a rapid thaw during the 22d of a heavy snow cover over the upper Allegheny River basin above Franklin, Pa., caused a major rise in the Allegheny River during which 6,900 acre-feet of water was stored in the reservoir. The Allegheny River at lock 4 crested at 18.8 feet on the 24th, while the reduction by this reservoir in combination with Tionesta, Mahoning, Crooked Creek and Cone- maugh Reservoirs was 2.5 feet, averting suspension of navigation for one day. Intermittent, mixed heavy precipitation during April 1-8, 1957 over the basin caused a series of minor to moderate rises in the reservoir which resulted in the reservoir reaching the highest level during the year, elevation 939.9 on the 9th or 29.9 feet above mini- mum pool. This represented an impoundment of 18,700 acre-feet above that pool or about 20 percent of the usable capacity of the reservoir. During the remainder of the year routine operations were made except on the occasion of 18 minor rises when some water was stored and released as river conditions permitted.

ELKINS, OHIO RIVER BASIN, W. VA. Location. The city of Elkins is located on the Tygart River in north central Randolph County, W. Va., approximately 155 miles south of Pittsburgh, Pa. It is situated at the downstream end of a long, broad reach of the upper Tygart Valley, approximately 75 miles above the mouth of the river. (See U. S. Geological Survey chart for Elkins, W. Va.) Existing project. The plan of improvement provides for di- verting flood discharges from the upstream arm of the loop of the natural river channel into an artificial cutoff channel, thereby bypassing the city of Elkins. The improvement consists of a fully impervious rolled-earth upstream diversion dike, approxi- mately 1,250 feet long; a diversion or cutoff channel, approxi- mately 1,600 feet long, 140 feet wide and 15 feet deep; a down- stream protection dike, approximately 2,500 feet long; controlled inlet and outlet conduits through the dikes; a pondage basin within the protected area to store storm runoff during diversion periods; and an incidental pondage basin upstream from the diversion dike to aid low water flow. The structures of the project will be adequate to provide complete protection of Elkins against the maximum flood of reasonable expectancy. The exist- ing project was authorized by the Flood Control Act approved June 28, 1938. The Federal cost of the completed project is $1,772,627; non- Federal cost $40,000. The average annual maintenance cost during the past five years was $2,500. FLOOD CONTROL--PITTSBURGH, PA., DISTRICT 1111 Local cooperation.

YOUGHIOGHENY RIVER RESERVOIR, OHIO RIVER BASIN, PA. Location. The dam site is located on the Youghiogheny River about 74.2 miles above its junction with the Monongahela River at McKeesport, Pa. It is 1.2 miles upstream from Confluence, Pa., and about 57 miles southeast of Pittsburgh, Pa. The reser- voir is located in Fayette and Somerset Counties, Pa., and Garrett County, Md. (See U. S. Geological Survey charts for Confluence, Pa., Accident, Md., West Virginia, and Pennsylvania.) Existing project. This provides for the construction of a reservoir dam of the rolled-earthfill type with separate uncon- trolled side channel spillway and tunnel outlet works. The dam is 1,610 feet long at the top, rises 184 feet above the streambed, and provides for the gross storage of 254,000 acre-feet of water from a tributary drainage area of 434 square miles. Of this storage 5,200 acre-feet are in permanent storage and the remain- ing 248,800 acre-feet are available for flood control, navigation aid, and pollution abatement purposes. The reservoir is operated as required for flood-prevention purposes as a unit of a coordi- nated reservoir system for the protection of Pittsburgh and the upper Ohio Valley generally. The project was selected for con- struction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938. The estimated cost for new work (1957) is $9,780,000. The average annual maintenance cost during the past 5 years was $41,000. 1112 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. Operation and main- tenance, general: The reservoir was operated for flood control, as required, and necessary repairs made to the structure and to the operators' quarters and grounds throughout the year. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th caused light flooding along the Youghio- gheny River and appreciable flooding along the Monongahela River during the 6th-7th between lock 6 (lower) and lock 2 (lower). The Ohio River crested at Pittsburgh at 24.87 feet on the 6th and at Wheeling, W. Va., (lock 12) at 34.75 feet on the 7th. This was the highest summer rise since July 1896 along the upper Ohio River Valley. The reduction made by this reser- voir at both Pittsburgh and Wheeling was 0.85 foot and in com- bination with the other seven reservoirs above Pittsburgh was 2.8 feet, and in combination with the other nine reservoirs above Wheeling was 3.0 feet. The reduction made by this reservoir in combination with the other reservoirs averted flooding along the Ohio River below Pittsburgh for one day and the greatest natural summer flood since August 1888. The Youghiogheny River at Connellsville crested at 14.0 feet on the 6th while the reduction was 1.8 feet. The period of flooding was reduced by one-half day. The water stored during this flood caused the reservoir to rise to elevation 1456.3 on the 8th or 17.3 feet above summer pool (1439.0). This level, the highest reached during the year, represents an impoundment of 52,600 acre-feet above summer pool (154,500 acre-feet) or about 53 percent of the usable flood control capacity of the reservoir. The water stored during this flood was also the maximum amount stored and the maximum percent of summer flood-control storage used during the year. Major direct flood-control benefits were achieved by this reservoir along the upper Ohio River valley between Pittsburgh and Wheel- ing and along the Youghiogheny River from the mouth to Con- fluence, Pa., and were estimated as follows: Pittsburgh Damage District (lock 2, Allegheny River and lock 2, Monongahela River to mile 25.4, Ohio River), $397,000; Wheeling District (mile 25.4 to mile 109.0, Ohio River), $171,400; Youghiogheny Damage District (mouth to Confluence, Pa.), $183,000. Heavy rainfall over the Monongahela River basin from the afternoon of December 13, 1956 until the afternoon of the 14th following 2 days of intermittent light to moderate rainfall caused a minor flood during the 14th-15th along a reach between lock 6 (lower) and lock 2 (upper). The Youghiogheny River at Con- nellsville crested at 10.2 feet on the 14th while the reduction by this reservoir was 2.9 feet averting light flooding for 1/2 day. Water stored in conjunction with Tygart Reservoir reduced the period of flooding at lock 2, Monongahela River, by 1/2 day and likewise reduced the period of suspension of navigation by one- half day. A total of 53,600 acre-feet of water was stored during this flood a anantecedent minor rise, raising the reservoir to elevation 1419 (winter pool) on the 18th. FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1113 Minor direct flood control benefits were achieved by this reser- voir along the Youghiogheny River and lock 2 pool, Monongahela River, and were estimated at $6,500. The water stored during this flood represented a rapid recovery in the low water storage. On December 8, 1956 the reservoir had fallen to elevation 1390.8, the lowest elevation for the 1956 low water season. It is to be noted that the water stored brought the reservoir up to winter pool in 10 days while maintaining the low water schedule. This is the earliest that winter pool has been attained during the low water storage season since 1950. Heavy rainfall from late on January 9, 1957 until early on 10th accompanied by a moderate thaw caused a major rise in the reservoir during which 26,700 acre-feet of water was stored. Water stored in conjunction with Tygart Reservoir averted sus- pension of navigation at lock 2 and consequent use of the floodway for one-half day. During the rise, water stored in the reservoir in conjunction with storage in Tygart, Conemaugh and Loyalhanna Reservoirs averted the Ohio River at Pittsburgh from exceeding pool limit. Heavy rainfall during January 28-29, 1957 accompanied by light snow melt caused a moderate rise in the reservoir during which 13,900 acre-feet of water was stored. The reduction made by this reservoir in combination with Tygart Reservoir at lock 2 was 2.1 feet, just averting flood stage and consequent use of the floodway. During the rise, water stored in conjunction with storage in Tygart Reservoir also prevented the Ohio River at Pittsburgh from exceeding pool limit. Heavy rainfall over the Monongahela River from early on Feb- ruary 9, 1957 until early on the 10th caused a minor flood during the 10th-llth along a reach between lock 6 (lower) and lock 2 (upper). The water stored during the flood caused the reservoir to rise to elevation 1436.7 on the 12th or 17.7 feet above winter pool, representing an impoundment of 44,900 acre-feet above that pool level, or about 30 percent of the usable flood-control capacity of the reservoir. This was the maximum percent of winter flood- control storage used during the year. Water stored in conjunction with Tygart Reservoir reduced the period of flooding and suspension of navigation at lock 2, Monongahela River by one-half day. During the remainder of the year routine operations were made in accordance with the low water schedule for maintaining satisfactory flows at Connellsville, Pa., except on the occasion of thirteen minor rises when water was stored, with the excess above normal schedule storage being released as river conditions permitted. Activities under reservoir management program comprising sanitation, conservation, land management, and operation and maintenance of public use facilities were continued. The total costs were $38,014, all for operation and maintenance. Condition at end of fiscal year. The dam is complete and the reservoir is in operation for flood control, navigation, and pollu- tion abatement purposes. For flood control, the reservoir is 1114 REPORT OF THE CHIEF OF ENGINEERS, U.

The dam site is located on the Mahoning River about 73 miles above its confluence with the Shenango River. It is about 10 miles above the existing Milton Reservoir Dam and 35 miles upstream from Warren, Ohio. The reservoir is located in Portage, Mahoning, and Stark Counties, Ohio. (See U. S. Geological Survey charts for Warren, Ravenna, and Alliance, Ohio.) Existing project. This provides for the construction of a reservoir dam with a partially controlled, concrete, gravity center spillway flanked by rolled-earthfill abutment sections joining the valley sides. The dam is 5,750 feet long at the top, rises 96 feet above the streambed, and provides for the gross controlled storage of 91,200 acre-feet of water from a tributary drainage area of 249 square miles. Of this storage 1,800 acre-feet are in per- manent storage and the remaining 89,400 acre-feet are available for flood control and water supply purposes in the industrialized Mahoning Valley below. The project was selected for construc- tion under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938. The estimated cost for new work (1957) is $6,432,000. The average annual maintenance cost during the past 5 years was $48,500. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1115 Operations and results during fiscal year. Operation and maintenance, general: The reservoir was operated effectively for flood control and for low water regulation, as required, and neces- sary repairs made to the structure and to the operators' quarters and grounds throughout the year. Intermittent, heavy thundershowers from late on August 4, 1956 until early on the 6th over the Mahoning River basin caused nuisance flooding in the vicinity of Warren, Ohio. The Mahoning River crested on the 6th, at Youngstown at 9.5 feet and at Warren at 5.2 feet. At Youngstown the reduction made by this reser- voir was 1.0 feet and in combination with Mosquito Creek Reser- voir was 2.05 feet. At Warren the reduction made by this reser- voir was 1.2 feet. Light flooding was averted at both Youngstown and Warren for 11/2 and 1 day, respectively. The Ohio River at Wheeling, W. Va., (lock 12) crested at 34.75 feet on the 7th. The reduction made by this reservoir at Wheeling was 0.1 foot, and in combination with the other nine reservoirs above Wheeling was 3.0 feet, averting flooding along the Ohio River for 1 day. The water stored during this flood caused the reservoir to rise to elevation 1024.5 on the 8th or 5.4 feet above the normal low water drawdown guide curve for this date. This represented an impoundment of 16,400 acre-feet above the guide curve or about 33 percent of the usable flood control storage capacity of the reservoir for this date. Moderate direct flood-control benefits were achieved along the Mahoning River valley and light benefits along the upper Ohio River valley between the mouth of the Beaver River and Wheeling and were estimated as follows: Youngstown Damage District (Mahoningtown to mile 55, Mahoning River), $71,300: Warren Damage District (mile 55 to and including New- ton Falls, Mahoning River), $51,600; Wheeling Damage District (mile 25.4 to mile 109, Ohio River), $20,000. Heavy rainfall from the afternoon of January 22, 1957, until early morning of the 23d over the Mahoning River basin ac- companied by a rapid thaw during the 21st-22d of a moderate snow cover caused light flooding along the Mahoning River in the vicinity of Warren, Ohio. Warren crested at 6.2 feet on the 23d while the reduction was 1.1 feet, reducing the period of flooding by one day. The Mahoning River at Youngstown crested at 9.25 feet on the 24th while the reduction by this reservoir was 1.65 feet. In combination with Mosquito Creek Reservoir the reduction was 2.65 feet averting light flooding for 11/2 days. During the rise 14,800 acre-feet of water was stored in the reservoir, equivalent to 1.1 inches of runoff, representing a sharp recovery in the low water storage. Major direct flood-control benefits were achieved along the Mahoning River valley and were estimated as follows: Youngstown Damage District, $135,200; Warren Damage District, $529,700. Mixed, heavy rainfall and sleet from the afternoon of April 3, 1957 until the afternoon of the 4th over the Mahoning River basin caused light flooding at Youngstown and Warren, Ohio. The Mahoning River crested on the 5th, at Youngstown at 11.6 feet and at Warren at 6.75 feet. At Youngstown the reduction 1116 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 made by this reservoir was 2.25 feet and in combination with Mosquito Creek Reservoir was 3.2 feet averting a major flood. At Warren the reduction made by this reservoir was 1.65 feet, also averting a major flood. The water stored during this flood and following moderate rise from mixed, heavy rainfall and sleet during the 7th-8th caused the reservoir to rise to the highest elevation of the year 1028.5 on the 9th or 8.8 feet above the normal low water storage guide curve for this date. This represented an impoundment of 30,700 acre-feet above the guide curve or about 64 percent of the usable flood control storage capacity of the reservoir for this date. This was the maximum amount and percent of flood-control storage used for the year. Major direct flood-control benefits were achieved along the Mahoning River valley and were estimated as follows: Youngs- town Damage District, $1,019,600; Warren Damage District, $1,613,900. Heavy rainfall during June 28, 1957 over the Mahoning River basin caused light flooding at Warren, Ohio. The Mahoning River crested on the 30th, at Youngstown at 9.05 feet and at Warren at 5.2 feet. At Youngstown the reduction made by this reservoir was 1.2 feet and in combination with Mosquito Creek Reservoir was 1.9 feet. At Warren, the reduction made by this reservoir was 0.85 foot, and reduced the period of flooding by one-half day. In conjunction with Mosquito Creek Reservoir light flooding was averted at Youngstown for one day. During the flood 8,600 acre-feet of water was stored replenishing the low water storage and brought the reservoir level back up to summer pool. Major direct flood-control benefits were achieved along the Mahoning River Valley and were estimated as follows: Youngstown Damage District, $42,300; Warren Damage District, $237,100. Routine operations were made during the remainder of the year in accordance with the low water schedule for maintaining satisfactory flows at Leavittsburg and Youngstown. A total of seven minor rises occurred during which water was stored according to the low water storage and release schedule. It is noteworthy that the runoff for the 4-month period ending August 1956, under summer regulation, was 8.3 inches or 425 percent of normal, an unique record. Activities under the reservoir management program com- prising sanitation, conservation, land management, and operation and maintenance of public-use facilities were continued. The total costs were $36,958, all for operation and maintenance. Condition at end of fiscal year. The dam is complete and the reservoir is in operation for flood control and low water regula- tion purposes in the industrialized Mahoning Valley below. Con- struction of the dam was started in January 1942 and completed in June 1943. All work relative to relocations and land acquisi- tion is complete. The total acreage involved has been acquired and consists of 6,931 acres in fee simple and flowage easements over 1,059 acres. Remaining work consists of provision on project lands of additional recreational facilities required to serve the public needs.

MOSQUITO CREEK RESERVOIR, OHIO RIVER BASIN, OHIO Location. The dam site is located on Mosquito Creek, 9 miles above the junction of the creek with the Mahoning River at Niles, Ohio, and about 18 miles upstream from Youngstown, Ohio. The reservoir is located in central Trumbull County, northeastern Ohio. (See U. S. Geological Survey charts for Bristolville and Kinsman, Ohio, and Pennsylvania.) Existing project. This provides for the construction of a reservoir dam of the rolled-earthfill type with outlet facilities through the dam, and an uncontrolled natural wasteway to dis- charge overflow from the reservoir. The wasteway is located at the upper end of the reservoir area on the low-lying reach of the Mosquito Creek-Grand River Divide and overflow will be dis- charged into the Grand River, a tributary of Lake Erie. The dam is 5,650 feet long at the top, rises 47 feet above the stream- bed, and provides for the gross controlled storage of 104,100 acre- feet of water from a tributary drainage area of 97 square miles. Of this storage, 96,100 acre-feet are available for low water regu- lation and flood-control purposes in Mahoning and Beaver Valleys below. A modicum of effect applies to the upper Ohio River valley, below the mouth of the Beaver River. Of the remaining 8,000 acre-feet, 6,000 acre-feet are available for water supply storage and 2,000 acre-feet are in permanent storage. The reser- voir is operated for flood-prevention purposes as a unit of a coordinated reservoir system. The project was selected for con- struction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938. The cost of the completed project is $4,035,400. The average annual maintenance cost during the past 5 years was $29,500. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. Operation and maintenance, general: The reservoir was operated effectively for flood control and for low water regulation, as required, and neces- sary repairs made to the structure and to the operators' quarters and grounds throughout the year. 1118 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Intermittent, heavy thundershowers from late on August 4, 1956, until early on the 6th over the Mahoning River basin caused a moderate rise in the Mahoning River. The Mahoning River crested on the 6th at Youngstown at 9.5 feet. The re- duction made by this reservoir was 1.05 feet. In combination with Berlin Reservoir, the reduction was 2.05 feet, averting moderate flooding for 11/2 days. The Ohio River at Wheeling, W. Va. (lock 12) crested at 34.75 feet on the 7th. The reduction made by this reservoir at Wheeling was 0.1 foot, and in com- bination with the other nine reservoirs above Wheeling was 3.0 feet, averting flooding along the Ohio River for one day. The water stored caused the reservoir to rise to elevation 902.4 on the 7th or 5.8 feet above the normal low water drawdown guide curve for this date. This represented an impoundment of 41,100 acre-feet above the guide curve or about 75 percent of the usable flood-control storage capacity of the reservoir for this date. This was the maximum amount and percent of flood-control storage used for the year. Moderate direct flood-control benefits were achieved along the Mahoning River valley and light benefits along the upper Ohio River valley between the mouth of the Beaver River and Wheeling and were estimated as follows: Youngstown Damage District (Mahoningtown to mile 55, Mahoning River), $74,800; Wheeling Damage District (mile 25.4 to mile 109, Ohio), $20,000. Heavy rainfall from the afternoon of January 22, 1957 until early morning of the 23d over the Mahoning River basin ac- companied by a rapid thaw during the 21st-22d of a moderate snow cover caused a moderate rise in the vicinity of Youngstown, Ohio. Youngstown crested at 9.25 feet on the 24th, while the reduction by this reservoir was 1.0 feet. In combination with Berlin the reduction was 2.65 feet averting moderate flooding for 11/ days. During the rise, 8,400 acre-feet of water was stored in the reservoir, equivalent to 1.6 inches of runoff, representing a significant recovery and replenishment in the low water storage for that date. Moderate direct flood-control benefits were achieved in the Youngstown Damage District and were estimated at $81,800. Mixed, heavy rainfall and sleet from the afternoon of April 3, 1957 until the afternoon of the 4th over the Mahoning River basin caused light flooding at Youngstown, Ohio. The Mahoning River at Youngstown crested at 11.6 on the 5th. The reduction made by this reservoir was 0.95 foot. In combination with Berlin Reservoir the reduction was 3.2 feet averting a major flood. The water stored during this flood, antecedent minor rise from heavy rainfall from the afternoon on the 1st until morning on the 2nd, and subsequent series of minor rises from mixed, heavy rainfall and sleet during the 7th-9th caused the reservoir to rise to elevation 902.15 on the 12th or 1.7 feet above the normal low water storage guide curve for this date. This represented an impoundment of 13,400 acre-feet above the guide curve or about 46 percent of the usable flood-control storage capacity of the reservoir for this date. Major direct flood-control benefits were FLOOD CONTROL--PITTSBURGH, PA., DISTRICT 1119 achieved in the Youngstown Damage District and were estimated at $430,700. Heavy rain showers from the afternoon of April 23, 1957 until morning of the 24th over the Mahoning River basin (except southwest portion) caused a moderate rise in the Mahoning River. The Mahoning River at Youngstown crested on the 25th at 9.1 feet, while the reduction made by this reservoir was 0.85 foot, just averting flood stage. During this rise 5,300 acre-feet of water was stored, equivalent to 1.0 inches of runoff. Heavy rainfall during June 28, 1957 over the Mahoning River basin caused a moderate rise in the Mahoning River at Youngs- town. The river crested at 9.05 feet on the 30th at Youngstown. The reduction made by this reservoir was 0.7 foot and in com- bination with Berlin Reservoir was 1.9 feet, averting light flood- ing for one day. During the rise 4,500 acre-feet of water was stored replenishing the low water storage. Minor direct flood- control benefits were achieved in the Youngstown Damage District and were estimated at $24,600. It is noteworthy that the runoff from the basin for the 4 months, May-August 1956, inclusive, under the period of summer regulations, while complying with the low water temperature control schedule at Youngstown, was 10.2 inches or 710 percent of normal, an unique record at the dam. A nominal minimum flow of five second-feet was passed during July 4-17, 1956, to main- tain some flow in the channel below the dam while the low water storage was conserved because of the steel strike in the Youngs- town area. During the remainder of July and until the end of October, because of the high runoff through August, storage was available for release in excess of normal schedule and was re- leased as down river summer conditions permitted or was dis- tributed according to the drawdown guide curves. Thus the augmented flows above scheduled low water requirements for the Mahoning River at Youngstown represented a very favorable temperature and flow regimen for river water users, the best since records commenced at the dam 13 years ago. On November 20, 1956 the reservoir had fallen to elevation 896.05, the lowest elevation for the 1956 low water season. This was the maximum autumn drawdown elevation of record and reflects the record- breaking above normal runoff conditions for the summer of 1956. Routine operations were made during the remainder of the year in accordance with the schedule for maintaining satisfactory flows and water temperature at Youngstown. A nominal mini- mum flow of five second feet was released from November 16, 1956 until April 8, 1957, while the net inflow was stored from the flood rises and nine minor rises in accordance with the low water storage schedule for subsequent release during the 1957 low water season. This is the third complete year that the City of Warren, Ohio diverted their water supply from Mosquito Creek Reservoir. The water withdrawal from the reservoir to their filtration plant was 3.432 billion gallons or 10,531 acre-feet, representing 13.1 percent of the available low water regulation and water supply storage. This is a slight decrease over the previous year. 1120 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Activities under the reservoir management program compris- ing sanitation measures, conservation, land management, and operation and maintenance of certain public-use facilities were continued. This work was limited as the State of Ohio has jurisdiction over recreation in the reservoir area. The total costs were $31,070, all for operation and maintenance. Condition at end of fiscal year. The dam and appurtenances are complete and are in operation for flood-control and low water regulation purposes in the industrialized Mahoning and Beaver Valleys below. Construction of the dam was started in July 1943, and was ready for beneficial use in January 1944. All work relative to relocations and acquisition of land is complete. The total acreage involved in the acquisition of land consists of 11,213.98 acres in fee simple and flowage easement over 275.21 acres. The State of Ohio has obtained a license from the Secre- tary of the Army for development and operation of recreation facilities in the reservoir area. The total costs to the end of the fiscal year were $4,343,244, of which $4,035,400 was for new work and $307,844 for operation and maintenance, general.

EXAMINATIONS AND SURVEYS The costs incurred during the year amounted to $170,643, of which $165,689 was for flood-control studies and $4,954 was for special studies. The balance unexpended on June 30, 1957, $19,354, plus an allotment of $108,800, a total of $128,154, will be applied to the completion of five flood-control studies and con- tinuation of one study. The balance unexpended on June 30, 1957, $8,046, plus an allotment of $29,000, a total of $37,046, will be applied to continuation of special studies. The additional sum of $117,000 can be profitably used during the fiscal year 1959 for work to be accomplished under this heading. 28. RESEARCH AND DEVELOPMENT Work under this heading consisted of collection of hydraulic and hydrologic data. The costs incurred during the fiscal year amounted to $4,560.

The harbor is situated on the north shore of Lake Superior, 106 miles northeasterly from Duluth, Minn. (See United States Lake Survey Chart No. 9.) 1127 1128 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Existing project. This provides for rock-filled timber crib breakwater piers 350 feet in length from the east and west points of the bay to narrow the entrance; for constructing concrete seawalls across the ledge at the southeast corner of the harbor; for dredging an anchorage area of 36.5 acres to a depth of 16 feet with depths near the entrance of 18 and 20 feet, and for a small boat basin 100 feet wide, 600 feet long, and 8 feet deep in the northwestern part of the harbor protected by a breakwater 600 feet long with a rubblemound shore connection. All depths are referred to low water datum for Lake Superior, which is 601.6 feet above mean tide at New York. The ordinary seasonal variation of water level extends from 0 to +1 foot above low water datum. The harbor is subject to extreme fluctuations of water level of a temporary nature, due to wind and barometric conditions, of about 1 foot above or below the mean lake level prevailing at the time. The estimate of cost for new work (1957) is $494,000. The average annual maintenance cost during the past 5 years was $800. The existing project was authorized by the following: 1 Acts Work authorized Documents Mar. 3, 1879 Breakwaters and dredging of anchorage area of 26 H. Ex.

Doc. 187, 81st Cong., 1st sess. 1 Contains latest published map. Local cooperation. The improvement authorized by the act of May 17, 1950, is subject to the conditions that responsible local interests give assurances satisfactory to the Secretary of the Army that they will-- a. Provide without cost to the United States all lands, ease- ments, rights-of-way, and spoil-disposal areas necessary for the construction and subsequent maintenance of the work, when and as required. b. Hold and save the United States free from damages due to the construction and subsequent maintenance of the works. c. Provide and maintain without cost to the United States, and in accordance with plans approved by the Chief of Engineers, a suitable and adequate wharf for the accommodation of small craft which shall be open to all on equal terms. d. Establish a competent and properly constituted public body empowered to regulate and manage the inner harbor facilities. Local interests were notified on September 29, 1950, of the required conditions of local cooperation. None of the above conditions have been complied with. Terminal facilities. There are two general merchandise wharves, and several fish wharves, all privately owned. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. The seawalls were extended 73 feet where the rock reef had disintegrated and had RIVERS AND HARBORS-ST. PAUL, MINN., DISTRICT 1129 lessened the protection of the harbor. The work was accomplished by hired labor at a cost of $2,135, all for maintenance. Condition at end of fiscal year. The existing project is about 77 percent complete. Project depths of 16 feet in the anchorage basin and 18 to 20 feet in the entrance channel are available. Private parties dredged 420,795 cubic yards of gravel from the harbor between 1922 and 1930 under permits and without cost to the United States. To complete the project there remains the construction of the inner small boat basin and protecting breakwater. The concrete seawalls and the breakwaters are in good con- dition. The gravel spit along the eastern side of the harbor is too low to prevent waves from rolling into the harbor during severe storm periods. The total costs of the existing project at the end of the fiscal year were $209,820 for new work and $130,245 for maintenance, a total of $340,065.

KNIFE RIVER HARBOR, MINN. Location. This harbor is located near the mouth of Knife River on the north shore of Lake Superior, 19 miles northeasterly from Duluth, Minn., and 7 miles southwest of Two Harbors, Minn. (See United States Lake Survey Chart No. 96.) Existing project. This provides for an entrance channel, of varying width, 10 feet deep from that depth in Lake Superior; an inner straight channel 8 feet deep, 50 feet wide, and 600 feet long with a spending beach at its inner end having a radius of 150 feet; northerly and southwesterly side channels 8 feet deep, 50 feet wide, and 150 feet and 250 feet long, respectively; and a breakwater about 210 feet long on the south side of the entrance. The project depths are referred to low water datum for Lake Superior, which is 601.6 feet above mean tide at New York. The ordinary seasonal variation of water level extends from 0 to +1 foot above low water datum. The harbor is subject to extreme fluctuations of water level of a temporary nature, due to wind and barometric conditions, of about 1 foot above the mean lake level prevailing at the time. The estimated cost for new work, revised in 1957, is $258,000. 1130 REPORT OF THE CHIEF OF ENGINEERS, U. S.

PORT WING HARBOR, WIS. Location. The harbor is situated on the south shore of Lake Superior, 34 miles easterly from Duluth. (See United States Lake Survey Chart No. 96, Lake Superior.) Existing project. This provides for the construction of two parallel piers at the entrance, 200 feet apart and 800 and 825 feet long, respectively, the piers to consist of 2 rows of piling filled in with slabs and topped with large rock; for the construction of a return pile revetment at the inner end of the east pier 45 feet in length, to preserve the sand spit from erosion; for dredging 2 inner channels 8 feet deep, one extending southerly 340 feet with a width of 60 feet, and one easterly, 1,170 feet with a width of 70 feet, from an irregular-shaped turning basin 15 feet deep at the inner end of the piers, and for dredging a channel 150 feet wide with a 15-foot depth between the piers. The project depth is referred to low water datum for Lake Superior, which is 601.6 feet above mean tide at New York. The ordinary seasonal variation of water level extends from 0 to +1 foot above low water datum. The harbor is subject to extreme fluctuations of water level of a temporary nature, due to wind and barometric conditions, of about 1 foot above or below the mean lake level prevailing at the time. The estimated cost for new work (1954) is $63,400. The portion of the dredging of the entrance channel to complete the project width and depth is considered unnecessary to meet present 1134 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 navigation requirements, and is excluded from the foregoing cost estimate. The cost of this portion of the work was last revised in 1954, and was estimated to be $22,600. The average annual maintenance cost during the past 5 years was $2,332.

Operations and results during fiscal year. Condition surveys and miscellaneous inspections and reports were made at a cost of $8,416. Repair of revetments and upper entrance breakwaters was accomplished at a cost of $55,248. All work was performed by hired labor and use of Government plant. The total cost was $63,664 for maintenance. Condition at end of fiscal year. The existing project is 75 percent complete. The breakwaters are in good condition except for a weakness occuring in about 300 feet of the substructure of the breakwater at the lower entrance, and the stone-covered portions of the breakwaters at the upper entrance are in need of minor repairs. The mooring pier at the Lily Pond requires repairs to halt movement and permit dredging to project depth adjacent thereto; the mooring pier at the Portage River harbor of refuge is in good condition. Annual redredging of channels will be required indefinitely. The controlling depth on June 30, 1957 was 25 feet. To complete the project there remains the extension of the lower entrance breakwater, and the necessary alteration or replacement of structures due to deepening of channels. RIVERS AND HARBORS-ST.

The harbor is located on the south shore of Lake Superior on the North Face of Keweenaw Point 31 miles north- easterly from the Upper Entrance to Keweenaw Waterway. It is a bay 4,900 feet long by 1,100 feet wide with a natural opening of 1,500 feet, but the opening, except for very small boats, is restricted to 130 feet. (See U. S. Lake Survey Chart No. 94.) Existing project. The project as authorized provides for a short entrance channel 130 feet wide through the reef with a depth of 14 feet: for a guide pier marking the entrance on the west side having a length of 98 feet; for an inner breakwater 170 feet in length; and for a harbor basin 380 feet wide, 420 feet long and 12 feet deep. However, local interests requested that the site of the harbor be changed from the western to the eastern part of Eagle Harbor bay in the vicinity of an abandoned Coast Guard station. The improvement contemplated by this change provides for dredg- ing a harbor basin approximately 200 feet wide and 900 feet long to a depth of 12 feet and removal of a timber-crib guide pier. The project depths are referred to low water datum for Lake Superior, which is 601.6 feet above mean tide at New York. The ordinary seasonal variation of water level extends from 0 to +1 foot above low water datum. The harbor is subject to extreme fluctuations of water level of a temporary nature, due to wind and barometric conditions, of about 1 foot above or below the mean lake level prevailing at the time. 1144 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The estimate of Federal cost for new work, (1957) based on the modified plan is $175,000, and $27,800 is to be contributed by local interests.

The improvement authorized by the act of March 2, 1945, is subject to the requirement that local interests: a. Contribute $27,800 in cash toward the cost of protective structures and dredging. b. Provide and maintain, without cost to the United States and in accordance with plans approved by the Chief of Engineers, a suitable and adequate public wharf for the accomodation of transient vessels. c. Establish a competent and properly constituted public body empowered to regulate the use, growth, and free development of harbor facilities (exclusive of Federal property) with the under- standing that harbor facilities shall be open to all on equal and reasonable terms. d. Hold and save the United States free from damages due to the construction and maintenance of the works. e. Provide, without cost to the United States, all lands, ease- ments, and rights-of-way necessary for the construction of the project. It is further provided that no work shall be done by the United States at this harbor until the prescribed requirements for local cooperation have also been complied with at the following addi- tional projects in this area: Grand Traverse Bay, Mich., Lac La Belle Harbor, Mich., and Chippewa Harbor, Mich. Assurances of local cooperation were approved on March 22, 1948. Local interests were unable to obtain necessary rights-of- way for the project as originally authorized which prompted the request to relocate the basin. Transfer of the Coast Guard property cannot be accomplished immediately. Because of the change in location of the basin, local interests will be required to formally agree to its relocation and other considerations. Terminal facilities. An old L-shaped timber wharf is available but is in poor condition. Operations and results during fiscal year.

There are two commercial fish wharves each 60 feet in length, not open to the public, one of which is served by a spur track. There are also a number of minor wharves. These facilities are ample for the needs of existing commerce. Operations and results during fiscal year. The United States hydraulic dredge Depoe Bay removed 77,000 cubic yards of material from the river channel and lake approach at a cost of $47,799, all for maintenance. Condition at end of fiscal year. The project as'a whole is complete except for the inactive portion. The protective jetty completed in 1910 and reconstructed as a rubblemound in 1929, is in good condition. The turning basin at the Warroad wharves was completed in 1911, and a channel 200 feet wide and 8 feet deep was completed in 1915. The controlling depths in the river channel and lake approach channel were 8 and 4 feet, respectively, below low water datum which is 1,056 feet above mean tide level at New York, for a least width of 100 feet. Annual maintenance is necessary. The shore revetment is in need of minor repairs. The uncompleted part of the existing project consists of widening the lake channel from 200 to 300 feet for a distance of 7,460 feet, and the turning basin from 250 by 900 feet to 500 by 900 feet. The additional widths are not necessary to meet present requirements.

For map, see p. 1978, Annual Report for 1911. 1150 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The cost of new work for the completed project was $881,985, exclusive of amount expended on previous projects. The average annual maintenance cost during the past 5 years was $79,968. The above dams are of solid concrete construction, Pokegama being built on bedrock and the others on pile foundations. The Sandy Lake Dam includes a lock 160 feet long, 30 feet wide, with a maximum lift of 9.5 feet and a depth of 2.5 feet on the lower sill at low water. The abandonment of the ditches to connect Long Lake to Round Lake and Round Lake to Gull Lake was recom- mended in House Document 413, 64th Congress, 1st session, and was ordered by Congress in the River and Harbor Act of July 27, 1916.

Fully complied with. Terminal facilities. None. Operations and results during fiscal year. A contract was awarded and completed for repairs to apron at Pokegama Dam at a cost of $42,994. A contract was awarded for repairs to Leech Lake Dam which has been brought to 7 percent completion. On June 4, 1957, the cofferdam extending from piers 26 to 39 failed and the rush of water resulting from the break undermined and washed out 11 piers of the permanent dam and damaged others. The cofferdam has been repaired and study of remedial measures to be taken is being made. The reservoirs were operated according to plan except for the variance necessary by the reconstruction of the apron at Winni- bigoshish Dam and by the failure of Leech Lake Dam. At the beginning of the fiscal year lake stages were normal for the four lower reservoirs while somewhat below normal for Winni- bigoshish and Leech reservoirs due to evaporation exceeding in- flow. Lack of sustained inflow precluded storage release from Leech Reservoir as an aid to the wild rice crop in Mud and Goose Lakes downstream. Winter drawdown was begun on schedule with all reservoirs near minimum levels before spring rise. Although runoff conditions were below normal the first half of the fiscal year, the spring runoff and subsequent rainfall was sufficient to fill the reservoirs. During the spring rise proper balance was maintained between Sandy Lake Reservoir, Pokegama Reservoir and Aitkin, Minn., all of these locations cresting below their respective flood stages. It is estimated that the reduction in stage at Aitkin, as a result of the operation of the reservoirs and the Aitkin diversion project, was about 0.2 and 3.3 feet, respectively. During the month of March the discharge at Winnibigoshish Dam was maintained at zero flow to facilitate repairs to the dam. RIVERS AND HARBORS-ST. PAUL, MINN., DISTRICT 1151 The closure of the dam caused about a 0.4 foot rise during the month to an 8.7 stage. After failure of the Leech Lake cofferdam on June 4, the uncontrolled flow from that lake reached a maxi- mum of about 2,500 second-feet. To partly compensate, the discharge at Winnibigoshish Dam was reduced from about 600 to 50 second-feet to reduce flooding of the area below the mouth of Leech Lake River. Flooding occurred principally from the Mud-Goose Lake area to the White Oak Lake area. The closure of the breach and the subsequent sheet-piling protection for the remainder of the dam was accomplished by June 26. Only a reduction of less than 0.5 foot occurred in Leech Lake levels due to the failure of the dam. Heavy rains coupled with the closure of Winnibigoshish Dam caused this reservoir to rise to a stage of 11.7 feet, about 1.2 to 1.5 feet above the desirable summer stage. Several complaints were registered by resort owners due to erosion of the banks. The storage at the end of the fiscal year amounted to 640,900 second-foot days. 1 Mean monthly stages for the fiscal year 1956 1957 Reservoir July Aug. Sept. Oct. Nov. Dec. Jan. Feb. Mar. Apr.

This river rises in Big Stone Lake, Minn., and S. Dak., and flows southeasterly about 224 miles to Mankato, Minn., thence northeasterly about 106 miles to join the Mississippi River opposite St. Paul, Minn. (For general location, see U. S. Geological Survey map of Minnesota.) Previous projects. The original project was adopted by the River and Harbor Act of March 2, 1867, and modified by the River and Harbor Acts of August 11, 1888, and July 13, 1892. For further details, see page 1890 of Annual Report for 1915, and page 1105 of Annual Report for 1938. Existing project. This provides for open-channel improve- ment from the Mississippi River to Shakopee (25.6 miles) to obtain a channel with 4 feet of water from the Mississippi River to Shakopee, which will accommodate vessels of 3-foot draft. The cost for new work for the completed project was $12,730, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $3,018. The existing project was adopted by the River and Harbor Act of July 13, 1892, (p. 2209 of the Annual Report for 1891). The latest published map will be found on page 1574 of the Annual Report for 1888. Local cooperation. None required under the existing project. Local interests on March 27, 1942, requested that the section of the chanel between the mouth and Savage, Minn., mile 13.2, RIVERS AND HARBORS-ST. PAUL, MINN., DISTRICT 1153 be dredged to a depth of 9 feet, and the Secretary of War, under authority contained in section 4 of the River and Harbor Act approved March 4, 1915, authorized acceptance of a total of $139,670.91 as local contribution to defray costs of dredging in excess of the authorized 4-foot project depth. Terminal facilities. At Port Cargill, mile 13.1, Cargill, Inc., owns and operates a launching ways, dock 650 feet in length with warehouse adjacent, with additional mooring space 1,300 feet in length and has facilities for loading grain and vegetable oils and receipt of coal. The Northern States Power Co. is operating a terminal for the receipt of coal on the left bank at mile 9.0, and the Richards Oil Co. is operating a terminal at mile 14.5, Savage, Minn. Operations and results during fiscal year. Fifty-five snags were removed by hired labor at a cost for the year of $1,685. Condition at end of fiscal year. The existing project was completed in 1931. Additional channel dredging (see "Local cooperation"), completed in July 1943, provides: A channel with minimum depth of 9 feet and a width of 100 feet from the mouth to Port Cargill, mile 13.1, except that the 9-foot depth is re- stricted to a width of 74 feet at the Chicago, Milwaukee, St. Paul & Pacific Railroad bridge mile 1.6; and a launching basin at Port Cargill, near Savage, Minn., with depths up to 20 feet. Depths in this reach greater than project depth are not dependable. Navigation was practicable from Port Cargill, mile 13.1, to Shako- pee for drafts not in excess of 3 feet. The total costs and ex- penditures under the existing project to June 30, 1957, were $102,999, being $12,730 for new work and $90,269 for mainte- nance. In addition, the cost and expenditure from contributed funds was $139,671 for new work dredging to a depth of 9 feet, under the provisions of section 4 of the River and Harbor Act of March 4, 1915.

ST. CROIX RIVER, WIS. AND MINN. Location. The source of the river is in northwestern Wis- consin. It is about 164 miles long and for its greater part forms the boundary between Wisconsin and Minnesota. It flows south- westerly and then southerly into the Mississippi River at Prescott, Wis., 41.7 miles below the lower Northern Pacific Railway bridge, Minneapolis, Minn. The portion included in this improvement 1154 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 extends from the mouth to Taylors Falls, Minn., a distance of 51.8 miles. (See United States Geological Survey map of Minnesota, scale 1:500,000, for general location.) Existing project. This provides for the maintenance of a channel, 9 feet in depth and of suitable width from the mouth to Stillwater, Minn., 24.5 miles, created by the improvement of the upper Mississippi River; a channel 3 feet deep at mean low water, between Stillwater and Taylors Falls (27.3 miles); im- provement of the harbor and waterfront at Stillwater; and a small boat harbor at Hudson, Wis. The estimate of cost of new work, revised in 1957, is $272,000. The average annual cost of maintenance for that portion of the project between the mouth and Stillwater during the past 5 years was $8,157. The latest authorization (1954) for maintenance work on the reach between Stillwater and Taylor Falls is limited to an expenditure of not to exceed $5,000 per year.

Local interests for Hudson Harbor are required to give assurances satisfactory to the Secretary of the Army that they will: (1) provide, without cost to the United States, all lands, easements, and rights-of-way necessary for con- struction of the project and subsequent maintenance, when and as required; (2) hold and save the United States free from damages due to the construction of the project; (3) provide and maintain, without cost to the United States, access roads, parking and storage areas, mooring facilities, and utilities, including a public landing with suitable supply facilities, open to all on equal terms; and (4) establish a competent and properly constituted public body empowered to regulate the use, growth, and free development of the harbor facilities with the understanding that such facilities shall be open to all on equal terms. Local interests have not been formerly requested to furnish assurances. Terminal facilities. At Stillwater there is a concrete paved levee, 550 feet long and 40 feet wide, sloping from the top of the riverbank to the water. There is also a piling and timber trestle wharf on the right bank, of which 276 feet is dock and 96 feet approach. At other points along the river, landing may be made on the banks. Facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance dredg- ing, consisting of the removal of about 43,603 cubic yards of material, was accomplished by Government plant and hired labor at a cost of $6,572. RIVERS AND HARBORS-ST. PAUL, MINN., DISTRICT 1155 Condition at end of fiscal year. All new work was completed in 1930, except the subsequently authorized harbor at Hudson. The extension to provide a 9-foot channel from the mouth to Stillwater was completed on August 12, 1938, when full pool at dam No. 3 of the Mississippi River canalization project was reached. The minimum draft from Stillwater to Taylors Falls is about 1 foot at extreme low water, and from the mouth to Stillwater, 9 feet.

The Houghton-Hancock bridge is a combination rail- road and highway bridge crossing the Keweenaw Waterway between Houghton and Hancock on the upper peninsula of Michigan. (See United States Lake Survey Chart No. 944.) Existing project. Provides for a new combination railroad and highway bridge to be constructed by the Michigan State Highway Department to replace an existing combination bridge completed in 1906. The center pier and fenders of the existing bridge result in inadequate horizontal clearances which present a serious ob- struction and hazard to navigation. The new bridge will provide a vertical lift span with vertical clearances of 100 feet above high water elevation 605.3 above mean tide of New York City and 250-foot horizontal clearance. The center of the new bridge will be located about 135 feet west of the center of the existing bridge. The existing bridge will be removed. The notice to alter the existing bridge was served on the owner on August 9, 1955 as authorized by the Truman-Hobbs Act of June 21, 1940, as amended. The estimated Federal share of the cost of new work, revised in 1957, is $4,120,000. The estimated cost to local interests, revised in 1957, is $6,480,000. Local cooperation. The Truman-Hobbs Act of June 21, 1940, provides that, upon notice to alter by the Secretary of War, the bridge owners shall (a) prepare and submit to the Secretary for approval, plans and specifications for the alteration of the bridge; (b) take bids for the alteration of the bridge in accordance with the approved plans; submit all bids to the Secretary together with a recommendation as to the most competent bid; submit a written guaranty that the total cost of the project will not exceed a stated 5Exclusive of $38,000 to be contributed by local interests. 6 Channels adequate for commerce. 7 Inactive. 8 Exclusive of $38,200 to be contributed by local interests. 9 No commerce reported. toAbandonment recommended in 1915 (H.

Existing project. The project includes improvements for local protection in the interests of flood control and major drainage to be accomplished by channel improvement, levees, etc., in addition to the construction of a multiple-purpose reservoir on Otter Tail River to control floods and, in conjunction with the previously authorized Federal reservoir projects at Baldhill site of the Sheyenne River and at Red Lake, to increase low flows for water supply and pollution abatement. The units in the comprehensive basin plan are shown on page 1159. The project was authorized by the Flood Control Act approved June 30, 1948, which authorized the appropriation of funds for the partial accomplishment of the plan. The Flood Control Act of 1950 authorized completion of the plan. The Public Works Appropriation Act, 1957, authorized the Chief of Engineers to acquire such lands as are beyond the legal authority of the city of Grand Forks to acquire, at a cost of not to exceed $100,000.

The improvements, with the exception of the Orwell Reservoir on the Otter Tail River, are subject to the conditions that local interests will (1) provide, without cost to the United States, all lands, easements, rights-of-way, and spoil- disposal areas necessary for the construction and subsequent maintenance of the project, when and as required; (2) hold and save the United States free from damages due to the construction and subsequent maintenance of those works; (3) maintain the channels after completion in accordance with regulations pre- scribed by the Secretary of the Army; and (4) make at their own expense all necessary changes to utilities, highways, and bridges, including aproaches. No local cooperation is required in connection with the reservoir on the Otter Tail River. Local interests for the Otter Tail and Rush River units were formally requested to furnish assurances on August 7, 1950, and January 26, 1954, respectively. Local interests for other units have not been formally advised in writing of the requirements of local cooperation. However, assurances have been furnished as follows, with dates of approval indicated: Wild Rice-Marsh, December 30, 1949; Sand Hill, January 9, 1950; Mustinka, June 16, 1950; Otter Tail, October 27, 1950; Grand Forks, July 23, 1953; and Rush, August 13, 1954. Local interests at East Grand Forks state that they are unable to furnish assurances at this time. Lands required for construction of the Wild Rice, Marsh, Otter Tail, Rush, Sand Hill, and Mustinka Rivers have been furnished. Lands for Grand Forks improvements have been furnished except for the modified levee alinement and floodwall which have been acquired by the Government. The completed Wild Rice River improvements were formally transferred to local interests effective August 1, 1952, those for Marsh River on August 2, 1954, those for the Otter Tail River on 1160 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 August 15, 1954, and those for the Rush River on December 3, 1956. Operations and results during fiscal year. Advance planning was carried on for the Grand Forks improvements and detailed planning was continued for Fargo-Moorhead improvements. Mis- cellaneous designs and public contacts were carried on for other units. Contracts for Mustinka and Rush River improvements were completed. Work on a contract for Sand Hill River improvements was brought from 37.5 to 95 percent completion. The contract for Grand Forks improvements was brought from 67.6 to 96 per- cent completion. Modification of the contract is being negotiated to provide for construction of a floodwall. The United States acquired 0.74 acre in fee for this work. Orwell Reservoir was operated according to plan throughout the year. During July and August 1956 the pool was allowed to fill from elevation 1048.0 msl (1912 adjustment) to about elevation 1059. During September and October the pool was maintained essentially between elevation 1059 and 1060 as a protective measure against fall floods. From October 28, 1956 to January 11, 1957, the pool was filled to elevation 1069.3. Thereafter, drawdown of the reservoir was initiated to supplement low water conditions. Discharges ranging from 75 second-feet to 230 second-feet were maintained until breakup about March 20, 1957, lowering the pool to about elevation 1061 during this time. Although minimum operating pool level is about elevation 1048, the pool was not allowed to drop to this elevation because of the lack of snow during the winter and the growing concern of a possible drought. However, heavy rains during the latter portion of May and in June 1957 dispelled these fears. As a result moderate discharges up to 750 second-feet or about bankfull discharge have been released from Orwell Dam during May and June. Due to the low runoff only slight reduction in stages downstream have been occasioned by the operation of the reser- voir. At the end of the fiscal year the pool was being maintained at about elevation 1059.5 and the discharge at about 660 second-feet.

RED LAKE RIVER, MINN., INCLUDING CLEARWATER RIVER, MINN. Location. The works covered by this project lie along the upper reach of the Red Lake River and also along the Clearwater River, a tributary of the Red Lake River, between a point near Plummer, Minn., and a point just above the mouth of Ruffy Brook. Red Lake River, the principal tributary of the Red River of the North, has its source at the outlet of Lower Red Lake in the northwestern portion of Minnesota and has a total length of about 196 river miles. It flows in a westerly direction to its junction with the Red River of the North at East Grand Forks, Minn. The meandering length of the Clearwater River in its general westerly course from its source near Ebro, Minn., to its junction with the Red Lake River at Red Lake Falls, Minn., is about 205 miles. (For general location, see U. S. Geological Survey map of Minnesota.) Existing project. The following features are included in the plan of improvement: Rectification and enlargement of 27.5 miles of the channel of the Red Lake River so as to provide sufficient channel capacity throughout the reach between river mile 154.3 near High Landing, Minn., and a point 4.5 miles east of the west boundary of the Indian Reservation, and the reach from the outlet of Lower Red Lake to a point 3.2 miles westerly thereof at which point an 80-foot concrete overflow structure with a fixed crest at elevation 1166.0 will be constructed to replace an existing rock and brush dam to restore the marshes adjacent to the channel. Modification of the existing stoplog structure, which was constructed at the outlet of Lower Red Lake by the Indian Service, so as to provide for the installation of three hand-operated lift gates, and one stoplog bay; raising 6.9 miles of highway at west end of Lower Red Lake to prevent overtopping; and rectifi- cation, clearing, and enlargement of 47.3 miles of the channel of the Clearwater River so as to provide sufficient channel capacity FLOOD CONTROL--ST. PAUL, MINN., DISTRICT 1163 between river mile 31.8 at Plummer, Minn., and mile 79.1 up- stream from the mouth of Ruffy Brook. The channel improve- ments eliminate a large percentage of the flood damages resulting from overflow of the rivers and provide adequate channels in Red Lake and Clearwater Rivers to carry the discharge from drainage ditches. Modification of the existing control works at the outlet of Lower Red Lake provides for a discharge capacity of 1,000 cubic feet per second through the structure when the lake is at normal elevation (1,174) and will insure the release of sufficient water to provide water supply and pollution abatement benefits to municipalities along Red Lake River, and to assist in such pro- vision along the Red River of the North below the mouth of Red Lake River. The estimated (July 1957) cost to the United States for comple- tion of the project is $2,844,030. The average annual maintenance cost during the past 5 years was $6,262. The project was authorized by the Flood Control Act approved December 22, 1944, (H. Doc. 345, 78th Cong., 1st sess.). The latest published map is contained in the project document. Local cooperation. The improvement is subject to the con- ditions that responsible local interests give assurances satisfac- tory to the Secretary of the Army that they will, without cost to the United States, provide all flowage easements and rights-of- way; hold and save the United States free from damages due to the construction works and operation; make a cash contribution of $33,220 in lieu of altering bridges; take over the maintenance and subsequent replacement of all bridges improved by the United States; maintain the improved river channels; control the con- tamination by rural areas and villages without sewer systems of Red Lake, Clearwater, and Thief Rivers; require that municipali- ties which discharge sewage into Red Lake, Clearwater, or Thief River treat their sewage before discharge into the streams so as to effect a reduction in the biochemical oxygen demand of not less than 85 percent for towns of 1,000 population or greater and of 35 percent for municipalities having a population of less than 1,000; and prevent the construction of any new dams or the raising of any existing dams in Red Lake, Clearwater, or Thief Rivers downstream from Lower Red Lake, Clearwater Lake, or Mud Lake unless authorized by the Department of the Army. Provisions of local cooperation for completed work have been complied with. Rights-of-entry were furnished as inicated in real estate final report submitted September 8, 1954, and local interests furnished $33,220 cash contribution of which $3,200 was refunded to them in July 1953 for alteration of the River Valley bridge performed by them. Completed portions of the project except the outlet structure, the control structures on Butcher Knife Creek, and the weir on the Red Lake River within the Indian reservation were formally transferred to local interests in two portions effective November 15, 1953, and November 5, 1954, respectively. Additional rights-of-way will be required for remedial measures on Red Lake River. Operations and results during fiscal year. The Red Lake Dam was operated in accordance with the prescribed plan. The pool 1164 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,. 1957 at the beginning of the fiscal year was at elevation 1174.4 msl (1929 adjustment) 0.4 foot above normal pool. However, due mostly to evaporation, the lake had receded to elevation 1173.5 by October 25. Evaporation during this time was almost 10 times greater than the average discharge of about 150 second-feet. From October 1956 through the middle of April 1957 little change in elevation of the lake was noted. During the latter period the discharge varied from about 250 to about 15 second-feet. Snow- melt runoff caused the lake to rise to elevation 1174.7 by the end of May. Heavy rains of about 8 inches during June caused Red Lake to rise to 1175.4 by the end of the fiscal year. It is estimated that the operation of the dam effected a decrease in stage of about 1.0-foot at Highlanding, Minn., and possibly 0.5 foot at Crookston. The crest stages at both latter places thereby being maintained only slightly above flood stage. Costs for the year for new work were $44 United States funds. Costs for the year for operating and care were $6,597. Total costs for the fiscal year were $6,641. 'Conditionat end of fiscal year. The project was completed in June 1956. However, additional funds have been received with which to replace the existing rock and brush dam with a concrete overflow structure and for closure of spoil banks and construction tie-back dikes along both sides of the Red Lake River to restore marsh conditions in the area to better wildlife condition. This work remains to be done. Construction initiated in February 1948, on the Red Lake River, and in October 1948, on the Clear- water River, has been completed. About 6,576,700 cubic yards of material were removed under the seven contracts embracing this work. Operation of the Red Lake Dam was taken over by the Department of the Army from the Department of the Interior, Office of Indian Affairs, on April 1, 1951. Channels are in good condition and have indicated the effectiveness of the project as a flood control measure. Total cost of new work for the project to June 30, 1957, was $2,791,095, of which $2,761,075 were Federal funds and $30,020 were contributed funds. Cost of operation and care was $35,647. Total costs were $2,826,742.

Dak., and 62.1 miles above the mouth of the Park River. South, Middle, and North Branches, the headwater streams of the Park River, rise in Cavalier County in northeastern North Dakota and flow in an easterly direction to an almost common confluence near Grafton, N. Dak., forming the main stream which flows easterly 35 miles to join the Red River of the North about 35 miles south of the international boundary. (For general location, see U. S. Geological Survey map of North Dakota.) Existing project. The following features are included in the plan of improvement: An earthfill dam, having a height of about 67 feet above the streambed and a length of 865 feet; a 5-foot inside diameter concrete conduit under the dam, with control gates located in tower at upstream end; and a spillway adjacent to the dam with 150-foot crest at an elevation of 19 feet below the dam crest and a chute with a bottom width of 150 feet. Partial flood control protection is afforded by the reservoir of 7,100 acre- feet capacity which is created by the dam, and the reservoir storage capacity of 3,650 acre-feet below spillway (1,080) is used to provide a flow of about 5 second-feet in the river to meet the water conservation needs in the reach from the dam to Grafton, N. Dak. In addition, a 16-inch cast-iron pipe water supply outlet through the dam has been provided at the request of local interests with payment by them. The estimate of cost to the United States for new work is $1,321,300. The average maintenance cost during the past 5 years was $18,246. The project was authorized as "Park River Reservoir" by the Flood Control Act approved December 22, 1944, (S. Doc. 194, 78th Cong., 2d sess.) and was redesignated "Homme Reservoir and Dam" by Public Law 435, 80th Congress, 2d session, approved March 5, 1948. The latest published map is contained in the project document. Local cooperation. The improvement is subject to the condi- tions that local interests make a cash contribution of $40,000 toward the construction cost, and give assurances satisfactory to the Secretary of War that they will provide, without cost to the United States, all lands, easements, and rights-of-way necessary for the construction of the project; make necessary changes in roads, bridges, and utilities; maintain the channel below the reservoir; hold and save the United States free from damages due to the construction works; limit future construction of dams below the reservoir; and prevent the discharge of raw sewage into the river by municipalities. Provisions of local cooperation have been fully complied with. Total costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal con- tributions, amout to $62,800. In addition, local interests contri- buted $16,220 for construction of a water supply outlet through the dam and incurred other costs amounting to $19,600. 1166 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Operationsand results during fiscal year. Funds were received with which to construct additional recreational facilities. Privies were constructed in one area and a well was driven in another area by hired labor. An access road to a third area was advertised but no bids were received. The structure was operated and necessary minor repairs were made by hired labor. Homme Reservoir was maintained at or near full pool, elevation 1180.0 msl (1929 adjustment), from the beginning of the fiscal year to October 1, 1956. During October the discharge from the reservoir was increased at the request of the City of Grafton to insure an adequate water supply for that town. This increased discharge was maintained most of the winter. By March 20, 1957, the pool was lowered to 1174.0 msl, 6.0 feet below full pool. High temperatures during the period March 20-22, resulted in a rapid runoff. The reservoir was filled and crested on March 23 about 1.1 feet above full pool at elevation 1081.1 msl with a peak discharge of about 335 second-feet. For the remainder of the fiscal year the pool has been maintained slightly above full pool elevation. Costs for the year for new work were $1,963 by hired labor. Costs of operation and maintenance for the year were $8,128. Total costs were $10,091. Condition at end of fiscal year. The project was completed in June 1956 except for additional recreational facilities for which funds were made available. Construction was initiated in April 1948, and major structures were completed in May 1951. Struc- tures are in good condition. Work remaining consists of construc- tion of an access road to Walsh Memorial Park and furnishing a well at that location. The total cost of new work for the project to June 30, 1957, was $1,371,479 of which $1,315,259 were Federal funds and $56,220 were contributed funds. Cost of operation and maintenance was $98,195.

LAKE ASHTABULA AND BALDHILL DAM, SHEYENNE RIVER, N. DAK. Location. The Baldhill Dam site is located on the Sheyenne River, 16 miles upstream from Valley City, N. Dak., and about FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1167 271 miles above the mouth. The Sheyenne River rises in central North Dakota and flows 500 miles generally southeast to enter the Red River of the North about 10 miles north of Fargo, N. Dak. (For general location, see U. S. Geological Survey map of North Dakota.) Existing project. The plan of improvement provides for the construction of an earthfill dam, having a height of about 61 feet above the streambed and a total length of 1,650 feet, with a con- crete spillway-control section consisting of a concrete gravity ogee section with overall length, including piers, of 140 feet. The crest is at elevation 1,252 and is surmounted by three standard design Tainter gates each 40 feet long and top elevation at 1,267. A gate-controlled 3-foot diameter conduit has been provided in each of the two center piers. The dam creates a reservoir of 70,700 acre-feet capacity and controls the runoff from an effective drainage area of 1,988 square miles, thereby providing a sub- stantial degree of flood control to the cities, villages, and urban areas along the Sheyenne River and providing substantial water supply and pollution abatement for the section of the Sheyenne River below the dam and the section of the Red River of the North below the mouth of the Sheyenne River. In order that a part of the regulated flow may be available for water supply and pollution abatement in the Red River of the North at Fargo, N. Dak., the plan also provides for the construction of a low diver- sion dam in the Sheyenne River 35 miles above the mouth, and a short ditch leading thence to the existing Stanley ditch, the latter to be cleared and deepened to the Red River of the North which it enters about 9 miles above Fargo. The estimated cost to the United States (1957) for new work is $2,706,300. The average estimated annual maintenance cost during the past 5 years was $28,278. The project was authorized by the Flood Control Act approved December 22, 1944 (S. Doc. 193, 78th Cong., 2d sess.). The latest published map is contained in the project document. The reser- voir above Baldhill Dam has been designated as Lake Ashtabula by Public Law 772, 81st Congress, 2d session, approved September 8, 1950. Local cooperation. The improvement is subject to the condi- tion that no funds shall be expended on construction of the project until local interests have contributed $208,000 towards the first cost of the reservoir and until responsible local agencies have given assurances satisfactory to the Secretary of War that they will (1) hold and save the United States free from damages due to the construction works; (2) bear the expense of all necessary alterations of utilities, roads, highways, and bridges; (3) construct, operate, and maintain the Fargo diversion dam and diversion ditch improvements in accordance with plans and regu- lations to be approved by the Secretary of War; (4) maintain the channels below the reservoir in satisfactory condition for the flow of water released from storage, to include the prevention of encroachments on the carrying capacity of the channel which would unduly interfere with the conveyance of floodwater; and 1168 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 (5) establish and enforce suitable regulations to prevent pollution of the water of Sheyenne River. Provisions of local cooperation have been complied with except for construction of the Fargo diversion dam and ditch, assurances for which, furnished by the city of Fargo, were approved by the Secretary of War on June 26, 1947. Plans for this feature have been prepared. Operations and results during fiscal year. Structures were operated as required and necessary repairs made by hired labor. Baldhill Dam was operated according to plan the entire fiscal year. The reservoir was slightly above full pool elevation 1266.0 msl (1929 adjustment) at the beginning of the year. No diffi- culties were encountered during the summer and fall in maintain- ing practically full pool and at the same time discharging the minimum required amounts. Immediately prior to ice formation on November 14, 1956, the discharge was increased from about 10 second-feet to 50 second-feet to assure adequate flow down- stream during time of ice formation. This discharge was later increased to about 100 second-feet in February. Due to the lack of snow cover during the winter and the possibility of drought conditions the pool was not drawn to the minimum operation level, elevation 1262.5, but was drawn only to elevation 1263.7. By conserving nearly all of the runoff the pool was filled by May 8, 1957. Continued rains during May and June resulted in runoff which maintained the pool above elevation 1266.0 for the re- mainder of the fiscal year. The discharge averaged about 50 second-feet during this latter period. No flooding was prevented by the operation of the reservoir due to the lack of spring runoff. Total costs for the year were $24,984, for operation and maintenance by hired labor. Condition at end of fiscal year. The project was completed in March 1956 except for construction of recreational facilities. Land acquisition for the project, included acquisition of 7,816.5 acres in fee and easements on 666.2 acres. Construction was initiated in July 1947 and major features were completed in November 1950. The dam was placed in emergency operation in April 1950 and in permanent operation in the spring of 1951. Structures are in good condition.

LAKE TRAVERSE AND BOIS DE SIOUX RIVERS, S. DAK. AND MINN. Location. The works covered by this project lie along Lake Traverse and Bois de Sioux River between the upper end of Lake Traverse at Browns Valley, Minn., and the mouth of Bois de Sioux River at Breckenridge, Minn. The lake drains through the river to the Red River of the North, and the two waters form a portion of the boundary between the State of Minnesota and the States of North and South Dakota. (For general location, see U. S. Geological Survey map of Minnesota.) Existing project. The plan of improvement provides for use of Lake Traverse as a flood control and water conservation reservoir and for channel improvement in the river below the lake. It includes construction of a dam near White Rock, S. Dak., at the north end of Lake Traverse, a structure at the Reservation Highway crossing for control of the upper section of the reser- voir, levees, and embankments necessary near Browns Valley, Minn., and channel improvement of approximately 24 miles of the Bois de Sioux River from the outlet of Lake Traverse north- ward toward Breckenridge, Minn. The dam near White Rock, S. Dak., consists of a control section with concrete abutments, piers, and stilling basin and 3 Tainter gates, each 13 feet wide by 16 feet deep between 2 sections of rolled-fill embankment with a total length of approximately 14,550 feet from high ground on the Minnesota side to high ground on the South Dakota side. This dam supplemented by channel improvement of the Bois de Sioux River downstream and an embankment approximately 5,000 feet long at the south end of Lake Traverse for the protec- tion of Browns Valley, Minn., constitutes the flood-control feature of the project. The structure at Reservation Highway crossing consists of a stone-paved dike spillway with superimposed stop- log spans with total length of approximately 113 feet between steel-sheet pile abutment walls behind which compacted fill with soil-cement slab pavement connects with the existing highway, and is operated to maintain the water level in the upper section of the lake. The project, with reservoir capacity for flood control of 137,000 acre-feet, affords protection to about 42,000 acres of agricultural land from floods up to those which may be expected to occur once in 30 years and has restored Lake Traverse to its former natural condition as a habitat for an abundance of wildlife and fish. The cost of the completed project was $1,332,200. The average annual maintenance cost during the past 5 years was $16,089. The existing project was authorized by the Flood Control Act approved June 22, 1936. Local cooperation. None required. Operations and results during fiscal year. The project was 1170 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 operated according to plan and necessary repairs were made by hired labor. The project was operated according to plan. At the beginning of the fiscal year Lake Traverse was a conservation elevation of 976.0 msl (1912 adjustment). White Rock pool was at elevation 971.0, 1-foot below conservation level. Rainfall during the first week of August caused a 0.3 foot rise in Lake Traverse by the tenth while White Rock pool rose to elevation 971.8 by August 21. No additional rainfall of consequence fell prior to the freeze- up. Evaporation gradually reduced both pools and minimum ele- vations of 975.5 and 971.2 at Lake Traverse and White Rock pools, respectively, were reached by October 31. During the winter through February, the pools remained at nearly these minimum elevations. Recovery in both pools began March 1, 1957, and on April 18, Lake Traverse and White Rock pool reached elevations 976.4 and 972.1, respectively. The spring break-up aided by rains occurring April 19 and 20 caused rapid rise in both pools. As a result discharge was released at White Rock Dam for the first time since about December 1, 1953. Lake Traverse and White Rock pool reached a maximum elevation of 977.0 and 974.2 on April 24 and 27, respectively. Thereafter both pools continued to fall gradually returning to their conservation levels the middle of May and have remained at or near these levels the balance of the fiscal year. Discharge from White Rock Dam continued and at the end of the fiscal year the flow through White Rock Dam was about 200 second-feet. Costs for the year were $17,842 for operation and maintenance by hired labor. Condition at end of fiscal year. The existing project was com- pleted in June 1948. Fee title to 1,315.48 acres and easements on 5,952.35 acres of land have been acquired. The White Rock dam and reservation control structure are in operation, and the struc- tures and appurtenances are in good condition. The roadways across structures are open to public travel. The total costs under the existing project to June 30, 1957, were $1,524,740, being $1,332,200 for new work and $192,540 for operation and maintenance.

MISSISSIPPI RIVER NEAR AITKIN, MINN. Location. The area under consideration lies mainly in Aitkin County in northeastern Minnesota, approximately 80 miles west of Lake Superior and about 100 miles north of Minneapolis and FLOOD CONTROL--ST. PAUL, MINN., DISTRICT 1171 St. Paul. The Mississippi River in this area flows in a general southwesterly direction through Aitkin County. Aitkin, Minn., is on the Mississippi River 1,055.9 miles above the mouth of the Ohio River. (For general location, see U. S. Geological Survey map of Minnesota.) Existing project. The following features are included in the plan of improvement. A diversion channel on a general east-west alinement between miles 1,064 and 1,040.4 on the Mississippi River, being a channel about 6 miles in length and, with the ex- ception of a contracted section at each end of the main diversion channel, a bottom width of 90 feet and 1 on 3 side slopes; a chan- nel about 1,100 feet in length permitting the Little Willow River to enter the main diversion channel and a 2,800-foot channel diverting Wakefield creek into the main diversion channel; ero- sion control structures at the mouth of the Little Willow and Wakefield Creek diversions and at one other point. In addition, 2 supplementary diversion channels are located downstream, the 800-foot Pine Knoll diversion between miles 1,040.9 and 1,040.1 and the 1,300-foot Tow Head Rapids diversion located between miles 1,031.4 and 1,030.5. The improvements alleviate the flood condition and improve drainage in and near Aitkin, Minn. The cost of the completed project was $1,672,535. The project was authorized by the Flood Control Act approved June 30, 1948 (H. Doc. 599, 80th Cong., 2d sess.). The latest pub- lished map is in the project document. Local cooperation. The improvement is subject to the condi- tions that responsible local interests give assurances satisfactory to the Secretary of the Army that they will (1) provide, without cost to the United States, all lands, easements, and rights-of-way necessary for the construction of the project; (2) hold and save the United States free from damages due to the construction works; (3) bear the expense of all necessary construction or alter- ations of utilities, roads, highways, and bridges; (4) maintain all works after completion in accordance with regulations prescribed by the Secretary of the Army; and (5) prevent future encroach- ment in the flood plain of the Mississippi River within limits of the project. The responsibility for local cooperation was assumed by the Aitkin Drainage and Conservancy District which has furnished assurances and provided necessary rights-of-entry to lands re- quired for construction. The project was transferred to local interests on December 24, 1956. Operations and results during fiscal year. Designs were com- pleted by hired labor. Remedial work on county ditch No. 11 and at the inlet control was accomplished during September, October, and November 1956. It is estimated that operation of the project in the 1957 high water resulted in a reduction in stage of about 3.3 feet in the vicinity of Aitkin. Costs for the year for engineering, including designs by hired labor were $6,083 and for construction by contract were $75,228. Total costs were $81,311. 1172 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Condition at end of fiscal year. Preparation of detailed plans and plans and specifications are complete. Construction was initiated in September 1952 and was completed in November 1956.

LAC QUI PARLE RESERVOIR, MINNESOTA RIVER, MINN. Location. The works covered by this project lie along Marsh and Lac qui Parle Lakes and the Minnesota River between the head of Marsh Lake and Granite Falls, Minn. (For general loca- tion, see U. S. Geological Survey map of Minnesota.) Existing project. Construction of the Lac qui Parle Reservoir was initiated as a Works Progress Administration project spon- sored by the State of Minnesota, prior to its authorization as a Federal project by the Flood Control Act approved June 22, 1936. The plan of improvement provides for completion and mainte- nance by the Department of the Army of the structures on Marsh and Lac qui Parle Lakes and the Chippewa River diversion works, substantially completed by the Works Progress Administration for use of Marsh and Lac qui Parle Lakes as flood control and water conservation reservoirs, and for channel improvement of the Minnesota River below the lakes. The project includes a main dam at the outlet of Lac qui Parle Lake, a structure between Marsh Lake and Lac qui Parle Lake, for control of the Marsh Lake Reservoir, a dam and diversion channel near Watson, Minn., for diverting floodwaters of the Chippewa River into the Lac qui Parle Reservoir, necessary alterations to highways, railroads, and bridges in the vicinity, and improvement of the channel of the Minnesota River at various locations between Lac qui Parle Lake and Granite Falls. The Lac qui Parle Dam, which carries a high- way across the Minnesota River, consists of a control structure of 12 bridge spans incorporating sluice gates and fixed spillway weirs, a 2,500-foot emergency spillway, and sections of highway embankment connecting with high ground on either side of the valley. The Marsh Lake Dam consists of a 112-foot concrete spill- way, and two sections of dredged earthfill totaling approximately 9,700 feet in length, including an auxiliary 90-foot grouted riprap overflow spillway. The Chippewa River flood diversion dam con- sists of a concrete fixed crest structure supporting a highway bridge, and section of earthfill through which is provided a con- duit for discharge of low water flow. The diversion channel for passing floodwaters of the Chippewa River into the Lac qui Parle FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1173 Reservoir is 3,500 feet in length cut through a natural ridge sep- arating the river and an arm of the lake and includes a 6-span con- crete submerged weir, also supporting a bridge, which allows a reverse flow from the lake. A rolled-earthfill dike extending along the lower south side of the channel is an extension of the diversion dam and serves also to protect the adjacent railroad tracks from being flooded. Completion of the project included improvements to Lac qui Parle Dam and spillway, improvements to Marsh Lake Dam, access roads, and dike, Great Northern bridge alterations, and construction of a Tainter gate at the Chippewa Dam, and stage-recorder houses. Improvement of the Minnesota River be- tween Lac qui Parle Lake and Granite Falls consists of rock removal, snag removal, and cutoffs at various locations to provide for increasing the bank-full capacity of the channel. The project, with reservoir capacity of about 96,700 acre-feet for flood control above normal elevations of the 2 conservation pools, provides pro- tection for agricultural lands against summer floods. Storage of 58,500 acre-feet for conservation purposes provided below normal elevations of conservation pools results in improved lake levels for recreation and game conservation in addition to providing for in- creased low water flow downstream for agricultural interests and for sewage disposal at Granite Falls. The estimate of cost (1957) to the United States for completion of the project is $942,000 including about $383,000 for lands and damages. The average annual maintenance cost during the past 5 years was $32,191. Local cooperation. None required. Operations and results during fiscal year. Work pertaining to transfer of land from the State of Minnesota to the United States was continued by hired labor. Structures were operated accord- ing to plans and necessary minor repairs were made to them. Lac aui Parle Reservoir was maintained at approximately conservation elevation, 931.2 mean sea level (1929 adjustment) throughout the fiscal year until after spring breakup. Higher stages were oc- casioned as the result of heavy rains during the period May 14 thru June 17, 1957. A crest stage of 940.35 msl (0.75 foot below the emergency overflow dike) was reached on June 29, 1957. Except for one day when a local rain of 7.5 inches fell in 24 hours the stage at Montevidio, the critical area downstream from the project, was maintained below flood stage. Until the heavy rains of May, the discharge from the dam remained below the downstream chan- nel capacity of 1,500 second-feet, the variation being from 1,200 second-feet in August to a winter low of about 25 second-feet. When the heavy rain of May 14 occurred it was apparent that the runoff would fill the pool rapidly, therefore the discharge from the dam was increased to channel capacity downstream. The pool rose to elevation 936.5 by June 6 and remained near this level with- out change in outflow until extremely heavy rain throughout the area on June 17 caused additional rise, reaching crest on June 29. The latter rain caused the release of flows in accordance with sum- mer flood-control procedure which resulted in a peak discharge of 1174 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 about 4,000 second-feet on the day of crest. On June 30, the day after crest, the pool elevation was 940.30. Costs for the year for new work were $916, being $258 for engineering by hired labor, and $658 for land acquisition activities. Costs for operation and maintenance were $17,730. Total costs were $18,646. Condition at end of fiscal year. Transfer of the project from the State of Minnesota to the United States was consummated on September 7, 1950. Previously operated by the State of Minne- sota, the project has been operated by the Government according to the approved plan of operation since that time. Easements on 32.8 acres of land have been obtained and fee title to 516.3 acres and easements on 19,642.6 acres of land are in process of acquisi- tion. Construction under the present plan of improvement was started in September 1941 and was completed in December 1951. All structures are in good condition. Completion of land acquistion will complete the project. Total cost under the existing project to June 30, 1957, were $1,148,666 of which $924,238 was for new work and $224,428 for operation and maintenance.

UPPER IOWA RIVER, IOWA Location. The works covered by the project include improve- ment of the Upper Iowa River in the vicinity of its mouth with an outlet through the floodplain west of the Mississippi River, about 1.5 miles south of New Albin, in the extreme northeast corner of the State of Iowa. (For general location see the U. S. Geological Survey map of Iowa.) Existing project. The plan of improvement provides for an adequate outlet for the Upper Iowa River and to improve the present channel above mile 0.2 by rectification of the existing channel from mile 4.2 to mile 0.2 and construction of a new outlet channel from the latter point to a point on Minnesota Slough opposite mile 671.5 on the Mississippi River, a distance of about 3 miles. The channel would accommodate a maximum discharge of 10,000 cubic feet per second. Spoil material would be placed FLOOD CONTROL--ST. PAUL, MINN., DISTRICT 1175 in levees which would give agricultural lands maximum protection from the design flow. The plan also provides for riprap protection at the railroad bridge and two highway bridges. The estimated cost to the United States for new work, revised in 1957, is $943,000. The project was authorized by the Flood Control Act approved September 3, 1954 (H. Doc. 375, 83d Cong., 2d sess.). The latest published map is in the project document. Local cooperation. The improvement is subject to the condition that local interests give assurances satisfactory to the Secretary of the Army that they will: (a) Furnish without cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas necessary for construction of the project; (b) hold and save the United States free from damages due to the construction works; (c) maintain and operate the project in accordance with regula- tions prescribed by the Secretary of the Army; and (d) prevent encroachments which would reduce the flood-carrying capacity of the channel. Assurances of local cooperation were approved on June 12, 1956. Local interests have acquired all privately owned lands and have been furnished rights-of-entry to the Government for those and other properties. Relocation agreements have been made by local interests with the highway departments. The drain- age district has obtained easements for necessary entry on lands controlled by the Corps of Engineers and the Department of the Interior. Operations and results during fiscal year. Preparation of de- tailed plans and plans and specifications were completed by hired labor. A relocation agreement was consummated with the Chi- cago, Milwaukee, St. Paul and Pacific Railroad Co. for removal of fences and poles. A contract for reach A, the lower 2.1 miles, was awarded and brought to 7 percent completion. About 40 percent of the clearing has been accomplished on this contract. Excavation has not been started. A contract for reach B, the upper 5.5 miles was also awarded and brought to 21 percent com- pletion. About 90 percent of the clearing has been accomplished and about 175,500 cubic yards of material have been excavated on the latter contract.

(ROCK ISLAND DISTRICT) For report on this improvement, see page 1203. 2. ILLINOIS AND MISSISSIPPI CANAL, ILL. Location. This canal connects the Illinois and the Mississippi Rivers, proceeding from a point on the Illinois River about 12 miles from La Salle across the State of Illinois to the Mississippi River at the mouth of Rock River. Existing project. This provides for the construction of a canal from the Illinois River, near Bureau, running westerly via the Bu- reau Creek Valley to Rock River, near Colona, thence in the bed 1179 1180 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of Rock River to the rapids near Milan, and thence to the Mis- sissippi River at the mouth of Rock River, at Rock Island, the length of the main line being 75 miles. The feeder, 29.3 miles in length, extends from Rock Falls on Rock River to the summit level of the canal, about 28 miles from the Illinois River. There are 32 locks in the main canal, described in the following tabulation. There is also a lock and controlling works at the head of the feeder at Rock Falls and a lock in Rock River at Rock Falls connecting the pool of the Government dam with the pool of the power company's dam below. This lock has dimensions similar to those in the main canal and cost $75,000. The cost of new work for the completed project was $7,605,- 143.41. The average annual maintenance cost during the past 5 years was $86,200. The existing project was authorized by the following: Acts Work authorized Documents Sept. 19, 1890 Existing project adopted_----------------------- H. Ex.

The latest published map is shown on page 2013 of Annual Report for 1908. Local cooperation. Fully complied with. Terminal facilities. None. Operations and results during fiscal year. The canal structures were not operated or maintained for purposes of navigation during the fiscal year. Minimal maintenance pending disposal of the canal was performed by hired labor. A detailed study of the problems involved in effecting disposal of the lands and facilities was in progress. Federal, State, and local governmental agencies and private interests were contacted to obtain their views relative to the use of the lands and facilities for park or other beneficial pur- poses, and assumption of the responsibility for future operation and maintenance. The costs during the fiscal year were $90,341 for operation and care. Condition at end of fiscal year. The existing project was com- pleted in 1918. Locks, dams, aqueducts, buildings, and other appurtenances are in fair-to-poor condition. Tabulation under paragraph "Existing project" gives data regarding the principal features of construction. Since June 30, 1951, canal structures have not been operated or maintained for purposes of navigation, in accordance with the policy of the Corps of Engineers to suspend lock operation and maintenance of waterways affording little or no benefit to general commerce and navigation, and to eliminate nonessential maintenance expenditures.

MILL CREEK AND SOUTH SLOUGH AT MILAN, ILL. Location. Mill Creek empties into South Slough about 1 mile east of the town of Milan, Ill., and 6.5 miles above the mouth of South Slough, which empties into the Mississippi River. Previous projects. Adopted by the River and Harbor Act of January 21, 1927. (For further details, see p. 1132, Annual Report for 1932, and p. 1081, Annual Report for 1938.) Existing project. This provides for floodgates in the walls of the Illinois and Mississippi Canal, or other devices for carrying the floodwaters of Mill Creek across the canal right-of-way into Rock River; for the construction of a levee on the east bank of Mill Creek extending from the Chicago, Rock Island & Pacific Railroad to the canal embankment; for the construction of a levee on the west bank of Mill Creek and its extension in a westerly direction to a connec- tion with Water Street at the point E, shown on map of project document; and for the removal of obstructions in Mill Creek and South Slough. The cost of new work for the completed project was $63,633.58. The average annual maintenance cost during the past 5 years was $4,100. The existing project was adopted by the River and Harbor Act approved July 3, 1930 (Rivers and Harbors Committee Doc. No. 19, 71st Cong., 2d sess.). The latest published map is in the project document. Local cooperation. Fully complied with. Terminal facilities. None. Operations and results during fiscal year. Hired labor forces cut and burned timber and brush along Mill Creek and South Slough in channel clean-out operations. The costs during the fiscal year were $15,000 for maintenance. Condition at end of fiscal year. The existing project was com- pleted in 1932. The project was in fair condition at the end of the 1184 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 fiscal year. The total costs under the previous project were $85 for new work and under the existing project to June 30, 1957, were $153,834, of which $63,634 was for new work and $90,200 was for maintenance.

THE SNY BASIN, ILL. Location. This project is located in the basin of the Sny, a former bychannel of the Mississippi River, in Pike, Adams, and Calhoun Counties, Ill., approximately miles 260.9 to 315.4 above the mouth of the Ohio River. The major tributaries of the Sny are McCraney, Hadley, Kiser, Six Mile, and Bay Creeks. Several minor tributaries include Fall, Pigeon, Horton, and Dutch Creeks. (The entire Sny Basin is shown on topographic maps of the U. S. Geological Survey, scale 1 : 62,500, dated 1921-28.) Existing project. The plan of improvement now being con- sidered for the prevention of interior flooding within the Sny bot- tom lands consists of construction of two retarding and desilting reservoirs for Pigeon Creek and for Horton-Dutch Creeks; con- struction of three diversion channels for McCraney-Hadley Creeks, Kiser Creek, and Six Mile-Bay Creeks to conduct the runoff from the uplands drainage area directly to the Mississippi River; im- provement of certain reaches of the Sny channel to collect bottom- land runoff; construction of three pumping stations; construction of a closing levee to exclude backwater up the Sny; construction of aqueducts or culverts to pass drainage which would otherwise be blocked; and the construction of remedial works necessitated by the improvements. FLOOD CONTROL--ROCK ISLAND, ILL., DISTRICT 1185 The estimated Federal cost for construction of the project is $21,000,000 (July 1957). The project was authorized by the Flood Control Act approved July 24, 1946, substantially in accord- ance with the recommendations of the Chief of Engineers in House Document 713, 79th Congress, 2d session. The latest published map is in the project document. Local cooperation. Section 3 of the Flood Control Act approved June 22, 1936, applies. In addition, local interests will be re- quired to furnish necessary authority to abandon obstructive bridges, and make all necessary alterations and relocations of highway bridges, roads, subsurface drains, and public utilities affected by the improvement. Local interests were informed of the local cooperation require- ments on September 8, 1947. Assurances, executed by the com- missioners of the Sny Island Levee Drainage District on February 9, 1948, were forwarded to the Chief of Engineers on July 25, 1952, and acceptance thereof was authorized on August 8, 1952. The assurances were formally accepted by the district engineer on September 6, 1952. In order that the Sny Island Levee Drainage District may raise the necessary funds to meet the local cooperation requirements, it will be necessary for them to secure court approval of the project. The drainage district must file a petition accompanied by detailed construction plans and rights-of-way maps in the county court. These plans and maps were furnished the drainage district by the district engineer on October 27, 1954. The commissioners of the drainage district, by formal action taken on May 12, 1955, author- ized and directed the attorney and the engineer for said drainage district to prepare and file in the county court, a petition setting forth the proposed plan of improvement, accompanied by rights- of-way maps, and to pursue said legal proceedings with a view to securing court approval of the project. As a preliminary step to obtaining court approval of the project, a reorganization of the district has been accomplished through court approval of a petition whereby certain independent subdistricts were merged with the Sny Island Levee Drainage District and additional protected areas were annexed to the district. The next action planned by local in- terests is to present the plan of improvement to the court for approval of the assessment and bond issue. The plans of the pro- posed work to be used as a basis for the assessment and bond issue have been completed by the commissioners and approved by the bond consultants. Operationsand results during fiscal year. Further preliminary planning for the project was, for the most part, held in abeyance during the fiscal year pending further progress on fulfillment of the requirements of local cooperation by the Sny Island Levee Drainage District. Work in connection with consultations and the furnishing of project information to local interests, and the col- lection of basic hydrologic data was performed by hired labor. The costs during the fiscal year were $5,194 for new work. Condition at end of fiscal year. Construction has not been started.

BEAR CREEK AT HANNIBAL, MO. Location. Bear Creek rises in Marion County, Mo., and flows easterly to its junction with the Mississippi River at a point 308.8 miles above the mouth of the Ohio River. The creek has a basin about 11 miles long and averaging 4.6 miles in width. The lower 3 miles of the stream are within the southeastern part of the city of Hannibal. Much of Hannibal's manufacturing and business districts and more than 500 homes are located in the Mississippi River and Bear Creek floodplains. The area is shown on topo- graphic maps of the U. S. Geological Survey, 1945, scale 1 : 62,500. Existing project. The plan of improvement authorized by this project consists of construction of a dam and reservoir on Bear Creek, about 5.4 miles above its mouth, together with remedial and appurtenant works, for the reduction of flood damages in the city of Hannibal. The proposed reservoir would have an initial storage capacity of 7,500 acre-feet which is equivalent to 5.1 inches of water depth over the drainage area of 27.6 square miles above the dam. Bear Creek floods with an average expectancy of once in 100 years would be contained in the reservoir; however, the reser- voir would provide no relief from Mississippi River floods alone. The estimated Federal cost for construction of the project is $3,330,000 (July 1957). The project was authorized by the Flood Control Act approved September 3, 1954, substantially in accord- ance with the recommendations of the Chief of Engineers in House Document 435, 83d Congress. The latest published map is in the project document. Local cooperation. Section 3 of the Flood Control Act approved June 22, 1936, applies. In addition, local interests will be required to pay for all necessary relocations except the relocation of rail- roads within and immediately downstream from the reservoir, and to prevent the construction of buildings, artficial fills, or any other obstructions within the city limits which, in the opinion of the Chief of Engineers, would reduce the flood capacity of the Bear Creek channel. The requirements of local cooperation have not been met in whole or in part. Local interests were informally ad- FLOOD CONTROL--ROCK ISLAND, ILL., DISTRICT 1187 vised of said requirements at a hearing on the subject at Hannibal on April 3, 1956. Local interests have not yet been requested to furnish assurances that the conditions of local cooperation will be met. After a firm project plan has been established, the city will be formally advised of the local cooperation requirements and requested to furnish the necessary assurances. Operations and results during fiscal year. Preliminary plan- ning, including field surveys, foundation investigations, design, and estimates, by hired labor, was continued during the fiscal year. The costs during the fiscal year were $60,615 for new work. Condition at end of fiscal year. Construction has not been started. Preliminary planning of the project is partially com- pleted. The total costs to June 30, 1957, were $106,898 for new work.

FABIUS RIVER DRAINAGE DISTRICT, MO. Location. The Fabius River Drainage District is located along the right bank of the Mississippi River, opposite the city of Quincy, Ill., 323.5 to 332.4 miles above the mouth of the Ohio River, in Lewis and Marion Counties, Mo. The District has an area of 14,264 acres. The area is shown on topographic maps of the U. S. Geological Survey, 1890-1943, scale 1 :62,500. Previous projects. A previous project for improvement of the levee system of the district was authorized by the Flood Control Act approved June 22, 1936. For further details, see page 1160 of Annual Report for 1941. Existing project. The plan of improvement consists of modi- fication of existing agricultural levees to provide increased protection to the district from Mississippi River floods. The estimated Federal cost for construction of the project is $2,500,000 (July 1957). The project was authorized by the Flood Control Act approved September 3, 1954, substantially in accordance with the recommendations of the Chief of Engineers in House Document 281, 83d Congress. Local cooperation. Section 3 of the Flood Control Act apprQved June 22, 1936, applies. Local interests have not yet been notified 1188 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of the local cooperation conditions nor requested to furnish assurances that said conditions will be met. Operations and results during fiscal year. Preliminary plan- ning, including field surveys, foundation investigations, design, and estimates, by hired labor, was initiated during the fiscal year. The costs during the fiscal year were $56,560 for new work. Condition at end of fiscal year. Construction has not been started. Preliminary planning of the project is partially com- pleted.

MISSISSIPPI RIVER AT CANTON, MO. Location. The work covered by this project is on the Missis- sippi River at the city of Canton, in Lewis County, Mo., 342.3 miles above the mouth of the Ohio River. Existing project. The project provides for local flood protec- tion at the city of Canton by means of diversion around the city, of Canton Creek and the runoff from the hills south of the creek, construction of levees and floodwalls with the necessary closure structures, and construction of two pumping plants with necessary intercepting ditches for removal of interior drainage. The esti- mated Federal cost for construction of the project is $1,060,000 (July 1957). The project was authorized by the Flood Control Act approved May 17, 1950, substantially in accordance with the recommendations of the Chief of Engineers in House Document 107, 81st Congress, 1st session. The latest published map is in the project document. Local cooperation. Section 3 of the Flood Control Act approved June 22, 1936, applies. In addition, local interests will be required to provide at their own expense all changes in highways and utili- ties including bridges and incidental remedial measures. Local interests were requested to furnish assurances of local cooperation on April 11, 1956. The city of Canton furnished formal assur- ances to the district engineer on August 20, 1956, but said assur- ances have not yet been accepted, pending receipt of evidence of the city's legal authority and financial ability to carry out the re- quirements. When a firm project plan has been developed, it will FLOOD CONTROL--ROCK ISLAND, ILL., DISTRICT 1189 be forwarded to the city for approval and for submission to the voters of Canton for a bond issue to finance the cost of local cooperation. Operations and results during fiscal year. Preliminary plan- ning, including field surveys, foundation investigations, design, and estimates, by hired labor, was continued during the fiscal year.

RED ROCK RESERVOIR, UPPER MISSISSIPPI RIVER BASIN, IOWA Location. The Red Rock Reservoir, on the Des Moines River, will be chiefly in Marion County, Iowa, but will extend into Jasper, Warren, and Polk Counties. The dam (Howell site) will be located approximately 142.9 miles above the mouth of the water- way which empties into the Mississippi River about 361.4 miles above the mouth of the Ohio River. The Iowa capital city of Des Moines lies northwesterly from the site on the banks of the river approximately 60 miles upstream. The entire watershed is shown on aeronautical maps of the United States Coast and Geo- detic Survey, scale 1: 500,000, dated 1937-38, Des Moines and Dubuque sections. Existing project. The plan of improvement provides for the construction of a dam consisting of a rolled-earthfill embankment and a gravity-type concrete spillway with crest gates, located near the center of the valley, each end of which will be tied into the embankment by a gravity-type nonoverflow, concrete section. The dam, at crest elevation of 798 feet above mean sea level, will be approximately 6,260 feet long and of maximum height of 95 feet above the valley floor. The proposed gated spillway is to be of concrete founded on bedrock with crest at elevation 744. The full flood-control level (top of crest gates) will be at elevation 780. The spillway crest gates, eight in number, will be 37 feet high and 40 feet wide. The outlet works, consisting of eighteen 5-foot by 8-foot gated conduits will extend through the spillway section and will discharge into the spillway stilling basin. The nonoverflow concrete sections of the dam at each end of the spillway will, be of the gravity type, firmly keyed into the foundation rock. The drainage area above the dam site is 12,250 square miles. With pool at full flood control elevation, the reservoir area FLOOD CONTROL-ROCK ISLAND, ILL., DISTRICT 1191 will be about 68,000 acres; the reservoir will contain approxi- mately 1,850,000 acre-feet of water at that height; 1,800,000 acre-feet of the reservoir will be allotted to flood control pur- poses; the remaining 50,000 acre-feet will be used for a con= servation pool which will furnish a minimum downstream flow of 300 cubic feet per second. The impoundment of flood waters by the reservoir will result in materially reduced flood heights on the Des Moines River below the dam, and will also provide substantial supplementary benefits by reducing Mississippi River floods. The latest estimate of cost of the project is $81,400,000 (July 1957). The Flood Control Act of December 22, 1944, authorized to be appropriated certain moneys for prosecution of the comprehensive plan approved in the Flood Control Act of June 28, 1938, for the Upper Mississippi River Basin, including the project for the Red Rock Dam on the Des Moines River substantially in accordance with the recommendations of the Chief of Engineers in House Document 651, 78th Congress, 2d session. The Red Rock project was made eligible for selection as a unit of the general comprehen- sive plan for flood control and other purposes in the Upper Missis- sippi River Basin under the aforementioned Flood Control Act of June 28, 1938. The latest published map is in House Document 651, 78th Congress, 2d session. Local cooperation. None required. Operations and results during fiscal year. Preliminary plan- ning, including field surveys, foundation investigations, design, and estimates, by hired labor, deferred since 1950, was resumed during the fiscal year.

This project is on the Iowa River, several miles up- stream from Iowa City, in Johnson County, Iowa, approximately 83 miles above the mouth of the Iowa River, which empties into the Mississippi River about 433 miles above the mouth of the Ohio River. Existing project. The plan of improvement provides for the construction of an earthfill dam rising approximately 100 feet above the streambed, a 500-foot uncontrolled spillway, outlet works to control the flow of the river to bankfull stage below the dam, and a reservoir providing for a controlled storage of 492,000 acre-feet, including a 17,000 acre-foot conservation pool. The Coralville Reservoir will be used to store Iowa River flows tem- porarily during flood periods. The project will minimize flood damages on the Iowa River from the dam to the mouth of the Cedar River, and will provide a large degree of protection for lands along the Iowa River below the mouth of the Cedar River. The proiect will effect significant reductions of Mississippi River flows at Keokuk, Iowa, and reduction of flows at Cairo, Ill. Incidental benefits to conservation and recreation will accrue from the proj- ect. Power development is not contemplated. The project was selected and approved by the Chief of Engineers as a unit in the general comprehensive plan for flood control in the Upper Mis- FLOOD CONTROL-ROOK ISLAND, ILL., DISTRICT 1193 sissippi River Basin authorized by the Flood Control Act of June 28, 1938.

SABULA, MISSISSIPPI RIVER, IOWA Location. The town of Sabula is located along the right bank of the Mississippi River in Jackson County, Iowa, 535.3 miles above the mouth of the Ohio River. The town is on a sandy ridge which is separated from the Iowa shore by a low swale or high water channel of the Mississippi River. The area is shown on topo- graphic maps of the U. S. Geological Survey, 1890-1943, scale 1 : 62,500. Previous project. A project for protecting the existing levees at Sabula against erosion and wave-wash was authorized by the Flood Control Act approved December 22, 1944; however, no con- struction was ever performed under this authorization. For further details, see page 1430 of Annual Report for 1947. Existing project. The existing project authorized a higher degree of flood protection to the town than was contained in the 1198 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 previously authorized project referred to in the preceding para- graph. The present plan of improvement consists of constructing 4,100 feet of new north levee along the Turnpike Road; construct- ing 2,100 feet of new east levee from high ground near the foot of Quarry Street to high ground at the southern edge of the town; constructing 3,800 feet of new south levee, mainly along the Chi- cago, Milwaukee, St. Paul & Pacific Railroad embankment crossing the submerged swale area; riprapping of the levees where neces- sary to protect from wave-wash; constructing roadway ramps; and providing necessary drainage structures. The project would protect the town against floods of a probable frequency of occur- rence of once in a hundred years. The project was authorized by the Flood Control Act approved September 3, 1954, substan- tially in accordance with the recommendations of the Chief of Engineers in House Document 281, 83d Congress. The estimated Federal cost is $407,000 (July 1957). The latest published map is in the project document. Local cooperation. Fully complied with. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $12,000 (1957 price level). Operations and results during fiscal year. Preliminary plan- ning, including field surveys, foundation investigations, design, estimates, plans, and specifications, was continued during the fiscal year. Construction of the north levee, by hired labor and equip- ment-rental contract, was initiated in December 1956, but weather conditions in January 1957 made further fill work impossible at that time and the contract was terminated. Clearing and grub- bing of levee foundations were continued by the hired labor force until March 1957. Work was resumed on the north levee in June 1957 by hired labor and a second equipment-rental contract. Con- struction of the remainder of the project consisting of levees and appurtenant works along the south and east sides of the town was initiated, by contract, in May 1957. The costs during the fiscal year were $81,792 for new work. Condition at end of fiscal year. The project is under construc- tion and is about 27 percent completed. The total costs to June 30, 1957, were $108,490 for new work.

This project provides for a channel of 9-foot depth and of adequate width between the mouth of the Missouri River (1,179 miles from the Gulf) and the Minneapolis, St. Paul & Sault Ste. Marie Railway bridge at Minneapolis, by the con- struction of a system of locks and dams, supplemented by dredg- ing. The project also provides for further improvements at St. Paul to provide a basin 9 feet deep, varying in width from 400 to 1,100 feet and extending downstream from the Robert Street Bridge for a distance of 2.7 miles, and at Minneapolis to provide adequate terminal facilities, and for miscellaneous and other harbor improvements. Pertinent data for existing and proposed locks and dams, etc., are given in table above. All dams are concrete. Three dams (St. Anthony Falls, 1, and 19) are fixed, the remainder are movable. The estimate of cost for new work, revised in 1957, is $225,491,000, which includes $33,300,000 for work upstream from the lower Northern Pacific Railway bridge at Minneapolis (St. Anthony Falls), but is exclusive of amounts expended on previous projects. The modification of the project providing for a harbor at Alma, Wis., is to be restudied and is excluded from this estimate. The cost of this portion was last revised in 1955 and was estimated to be $52,000. Also excluded from the estimate is $205,000 (1955) for Remedial Works in Sny Island Levee Drain- age District, Illinois, to be restudied after completion of the Sny Basin flood-control project. The average annual maintenance cost during the past 5 years was $4,303,851. See House Document 669, 76th Congress, 3d session, for a report of Chief of Engineers dated February 27, 1940, containing a general plan for improvement of the Mississippi River between Coon Rapids Dam and the mouth of the Ohio River for purposes of navigation, power development, the control of floods, and the needs of irrigation.

Existing project. This provides for protecting the mouth of the river by parallel piers 400 feet apart and about 1,870 and 2,681 feet in length for the north and south piers, respectively; for a channel 21 feet deep from that depth in the bay to the upper end of the Marinette municipal wharf, about 4,700 feet above the Ogden Street Bridge, and 10,700 feet from the outer end in the bay where the width is 600 feet, reducing to 300 feet between the piers and up to Ogden Street Bridge, thence 200 feet in the river to the upper end of the municipal wharf, with an enlarged turning basin 21 feet deep on the south side of the channel just below that wharf, and for a channel 12 feet deep and generally 90 feet wide upstream from the upper end of the municipal wharf for a distance of 2,500 feet to the vicinity of the Marinette Yacht Club. Except for 168 feet of concrete caissons at outer end of south pier, the piers are formed of stone-filled piling and timber cribs, the entire north pier and 2,156 feet of the south pier having been repaired with concrete superstructure. The project depths are referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage, and extreme fluctua- tions of a temporary nature, due to wind and barometric pres- sures, of several feet above or below the mean lake level prevailing at the time. The cost for new work was $149,505 exclusive of amounts ex- pended on previous projects. The average annual maintenance cost during the past 5 years was $79,900.

RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 1221 Operations and results during fiscal year. Condition surveys were made at a cost of $6,076. The total cost was $6,076. Condition at end of fiscal year. The project in effect prior to the modification of March 2, 1945, was completed in 1938. No additional work was necessary under the modification of March 2, 1945, to provide a depth of 12 feet in the extension of the channel to the vicinity of the Marinette Yacht Club as project depth or more was available. The entrance piers were com- pleted in 1884, and are in generally fair condition except for portions of the south pier which require repairs. Dredging of the channel below the Marinette municipal wharf and enlarging the turning basin, to existing project depth, was commenced in May 1938, and completed in November 1938. The inner 654 feet of the north pier is no longer essential for the preservation of the channel and is therefore maintained for a length of about 1,216 feet. The controlling depths at low water datum at the close of the fiscal year were 20 feet in the channel to the Marinette municipal wharf and in the turning basin; thence 12 feet to a point 300 feet east of the upper limit of the project; thence 9.7 feet to project limit. The river is available for rafting and logging for about 102 miles above its mouth. The costs under the existing project were $149,505 for new work and $940,095 for maintenance, a total of $1,089,600.

The wharf and landing facilities are, in general, adequate for the accommodation of existing commerce. Operations and results during fiscal year. Condition surveys, discharge observations and inspections and reports were con- ducted by hired labor at a cost of $8,506. The locks and dams were operated as required and the necessary repairs made to the structures at a cost of $232,974. The total maintenance costs were $241,480. Condition at end of fiscal year. The existing project is about 44 percent complete (upper river, 25 percent; lower, 83 percent). Twenty-two original locks and nine original dams have been re- built; five additional locks and dams have been built by the United States. (See existing project for year of completion of each.) The structures and the dredging in pools have increased the original depths generally about 2 feet. The controlling depths at standard low water at the close of the fiscal year were as follows: Fox River: De Pere to mouth of Wolf River---------- ------ 6.0 Thence to Eureka lock_________________________________ 4.0 Wolf River: Mouth to 1 mile below Partridge Crop Lake-_ 4.0 Thence to New London_____________________________ 4.0 Harbors on Lake Winnebago ____________________---______- 1.0-3.0 The practicable vessel drafts are about one-half foot less than the controlling depths which prevail throughout the year except when the rivers are frozen, usually from December 1, to April 1. As commerce no longer existed on the upper Fox River from the Wolf River to the Wisconsin River, Federal expenditures for continuing the operation of the nine locks on this portion of the project were no longer justified. Accordingly the operation of these structures was discontinued in July 1951. The work re- maining to be done to complete the project is dredging in the upper Fox River and the upper portion of the Wolf River and rock removal and deepening Neenah Channel on lower Fox River; which are no longer considered necessary. Except for Menasha lock, which should be rebuilt, the existing locks and dams are in generally fair to good condition.

In addition, the sum of $3,795,496 (including $89,309 under previous projects) was expended between July 5, 1884, and June 30, 1935, on the operat- ing and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes. 5. STURGEON BAY AND LAKE MICHIGAN SHIP CANAL, WIS. Location. This improvement is on the west shore of Lake Michigan, distant about 52 miles northeasterly from Green Bay and about 128 miles northerly from Milwaukee. (See U. S. Lake Survey Chart No. 728.) Previous projects. Adopted by River and Harbor Acts of March 3, 1873, and June 14, 1880. The United States assumed possession of the canal April 25, 1893, as authorized by the River and Harbor Act of July 13, 1892. The original project for the canal was adopted by the River and Harbor Act of August 18, 1894, modified by River and Harbor Act of June 3, 1896. For further details, see page 1935 of Annual Report for 1915 and page 1441 of Annual Report for 1938. Existing project. This provides for an outer harbor or stilling basin protected by two converging breakwaters, each 1,344 feet in length, extending from the shore on either side of the easterly or Lake Michigan end of the canal; for a revetted canal 7,200 feet in length, varying in width from 160 to 250 feet; for a channel 23 feet deep in rock cut, extending from that depth in Lake Michigan to about 800 feet west of the east entrance of the revetted canal, a length of about 0.6 mile; thence a channel 22 feet deep through an additional 6,400 feet of revetted canal and through Sturgeon Bay to the vicinity of Sherwood Point, a length of about 8 miles, the total length of channel being about 8.6 miles; the width of channel being 600 feet in Lake Michigan, reducing to 200 feet through the harbor and 130 to 220 feet through the revetted canal, thence 250 feet through Sturgeon Bay to a point 5,400 feet north- west of the railroad bridge in the city of Sturgeon Bay and thence 500 feet to the vicinity of Sherwood Point; for a turning basin 20 feet deep, on the southwesterly side of the channel, southeasterly of the highway bridge, between the city and the Bushman wharves; and that the turning basin immediately west of the revetted canal be eliminated from the project. The breakwaters are formed of stone-filled piling and timber cribs and have been provided with concrete superstructures; the revetments are formed of timber and steel piling, 886 feet having been provided with concrete superstructure. The project depth is referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage, and extreme fluctua- tions of a temporary nature, due to wind and barometric pressure, of several feet above or below the mean lake level prevailing at the time. RIVERS AND HARBORS--CHICAGO, ILL., DISTRICT 1231 The cost for new work for the completed project was $736,303, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $103,100.

Fully complied with. Terminal facilities. As the canal and connecting channel is a through waterway, the only terminal facilities are in the city of Sturgeon Bay, 4 miles from the west end of the revetted portion of the canal. These facilities consist of four coal wharves, four shipbuilding yards, and one package-freight wharf. The city of Sturgeon Bay has provided a public wharf. There is also a large inactive stone wharf located about 5 miles northwesterly from the city of Sturgeon Bay. The facilities are considered adequate for existing commerce. Operation and results during fiscal year. Condition surveys were made at a cost of $8,007. The reconstruction of 620 linear feet of south revetment was started in May 1957, with fiscal year 1957 costs of $136,840. The reconstruction will be completed in fiscal year 1958. Total maintenance costs were $144,847. Condition at end of fiscal year. The existing project was com- pleted in 1946. The breakwaters were completed in 1880, and the canal revetments in 1903. Dredging and rock removal at the easterly entrance to the canal and dredging in the westerly section of the canal, to existing project depth, were commenced in May 1940, and completed in September 1940. Deepening and widening the middle section of the canal to existing project depth and width was commenced in May 1942, and completed in August 1942. Dredging of the turning basin was commenced in June 1946, and completed in July 1946. The breakwaters are in good condition. The canal revetments require repairs and backfilling. The controlling depths for practicable widths at low water datum at the close of the fiscal year were 20.9 feet in the canal and 18.2 feet in the turning basin. The costs under existing project were $736,303 for new work and $2,142,363 for maintenance, a total of $2,878,666. In addition, the sum of $425,259.17 (including $189,319.35 under previous projects) was expended between April 25, 1893 and June 30, 1917, on the operating and care of the works of improvement under the provision of the permanent indefinite appropriations for such purposes. 1232 REPORT OF THE CHIEF OF ENGINEERS, U.

KEWAUNEE HARBOR, WIS. Location. On the west shore of Lake Michigan, distant about 105 miles northerly from Milwaukee and about 78 miles from Green Bay, via Sturgeon Bay Canal. The harbor is at the mouth of the Kewaunee River. (See United States Lake Survey Chart No. 73.) Previous projects. The original project was adopted by the River and Harbor Act of March 3, 1881. For further details, see page 1936 of Annual Report for 1915, and page 1447 of Annual Report for 1938. Existing project. This provides for a converging north break- water and shore connection about 3,130 feet long, removal of about 1,400 feet of the total length of about 1,850 feet of the north pier, a south pier about 1,850 feet long, an entrance channel, about 2,800 feet long and 20 feet deep, leading to an interior turning basin of the same depth, the entrance channel to have a general width, of 505 feet for a distance of about 1,500 feet through the outer basin, decreasing thence to about 156 feet between the piers to the turn- ing basin; also for removal of the outer south shoal to a depth of 22 feet. The parallel piers are formed of stone-filled piling and are capped with concrete superstructure, except for 216 feet of the south pier which consists of steel sheet piling. The north break- water is formed of concrete caissons and the north-shore connection is a rubble mound. The project depth is referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage, and extreme fluctua- tions of a temporary nature, due to wind and barometric pressure, of several feet above or below the mean lake level prevailing at the time. The cost of the completed portion of the project is $492,057, exclusive of the amount expended on previous projects. The August 30, 1935, River and Harbor Act portion of the project is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1954 and was estimated to be $668,000. The average annual maintenance cost during the past 5 years was $40,700.

These facilities are considered adequate for existing commerce. Operations and results during fiscal year. Condition surveys were made at a cost of $3,822. Structural repairs were made at a cost of $95,640. The U. S. dipper dredge Kewaunee during the period 18 March to 8 April 1957 removed 47,165 cubic yards of material at a cost of $29,207. Total maintenance costs were $128,669. Condition at end of fiscal year. The existing project is com- plete except for the inactive portion of the project which consists of removal of the outer shoal and an additional 700 linear feet of the north pier; widening of the inner 700 feet of the channel through the outer basin, and closing the gap in the north shore connection, all of which is not considered necessary under present conditions. The piers were completed in 1897 and are in generally good condition except that the south pier requires repairs. Con- struction of the north breakwater and shore connection, except for a gap of 150 feet about 830 feet from the shoreward end, and the removal of the outer 706.5 linear feet of the north pier were commenced in September 1935 and completed in June 1937. Dredging the entrance channel and interior basin, to existing project depth, was commenced in April 1938 and completed in October 1938. The controlling depth at low water datum at the close of the fiscal year was 20 feet in the south 160 feet of the entrance channel, and 20 feet between the piers and over an area 500 by 500 feet in the interior turning basin. The Kewaunee River is navigable for a distance of about 61/ miles above the mouth for craft drawing not more than 4 feet.

TWO RIVERS HARBOR, WIS. Location. This harbor is on the west shore of Lake Michigan, distant about 82 miles northerly from Milwaukee and about 101 miles from Green Bay via Sturgeon Bay Canal. (See United States Lake Survey Chart No. 73.) Previous projects. Adopted by the River and Harbor Act of March 3, 1871. For further details, see page 1936 of Annual Report for 1915, and page 1450 of Annual Report for 1938. Existing project. This provides for two entrance piers at the mouth of Twin Rivers, 245 feet apart at the outer ends and 750 feet apart at the shore line, having lengths of about 1,642 feet and 1,720 feet for the north and south piers, respectively; for a channel 2,600 feet long and 18 feet deep extending from that depth in the lake to an inner basin of the same depth at the confluence of the East and West Twin Rivers, the channel varying in width from 500 feet at the outer end to 200 feet between the piers; for a revet- ment about 450 feet long on the north side at the inner end of the channel and for a small stilling basin beyond the shoreline on the north side of the channel. The piers are formed of stone-filled tim- ber cribs and piling, and have been provided with concrete super- structure; the pile revetment on north side of channel is also provided with concrete superstructure. The project depth is referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage and extreme fluctua- tions of a temporary nature, due to wind and barometric pressure, of several feet above or below the mean lake level prevailing at the time. The cost of the completed portion of the project is $74,722, ex- clusive of the amount expended on previous projects. The August 30, 1935, River and Harbor Act portion of the project is considered to be inactive and is excluded from the foregoing estimate. The cost of this portion was last revised in 1954 and was estimated to be $14,300. The average annual maintenance cost during the past 5 years was $44,100.

Recommended modification of project. The Chief of Engineers in House Document 362, 84th Congress, 2d session, recommends that the existing project for Two Rivers Harbor, Wis., be modified as follows: Part A, extension of the navigation channel in the West Twin River for a distance of 300 feet with a depth of 18 feet, and Part B, extension of a navigation channel in the East Twin River from the upper limit of the existing project to 22nd Street bridge at a width of 100 feet and depth of 10 feet. The estimated first cost for this modification as contained in the document is $66,000. Operations and results during fiscal year. Condition surveys were made at a cost of $878. The United States dipper dredge Kewaunee, during the period 20 April to 9 May 1957, removed 54,885 cubic yards of material at a cost of $24,679. Preliminary costs in connection with the repair of 450 feet of section G of the north revetment amounted to $9,465. Total maintenance costs were $35,022. Condition at end of fiscal year. The existing project is com- plete except for the inactive portion of the project which con- sists of dredging a 10-foot width along each side of the lakeward portion of the entrance channel between the piers. This dredging was omitted to avoid removal of necessary riprap along the entrance piers. The present width of channel is considered ade- quate for present and reasonably prospective commerce. The south pier was completed in 1883 and is in generally good con- dition. The north pier was completed in 1908. The north revetment, completed in 1917, is in need of repair. Dredging of the entrance channel and inner basin to existing project 'depth was commenced in March 1937, and substantially completed in May 1937. The controlling depth at the end of the fiscal year, at low water datum was 18.0 feet in the channel between the piers and 16.8 feet in the inner basin. East and West Twin Rivers are navigable for about 3 and 7 miles, respectively, from the harbor piers for craft drawing not more than 4 feet. The costs under the existing project were $74,722 for new work and $884,719 for maintenance, a total of $959,441. 1236 REPORT OF THE CHIEF OF ENGINEERS, U. S.

This harbor is on the west shore of Lake Michigan, distant about 79 miles northerly from Milwaukee and about 106 distance about 79 miles northerly from Milwaukee and about 106 miles from Green Bay via Sturgeon Bay Canal. (See United States Lake Survey Chart No. 735.) Previous projects. The original project was adopted in 1854, the first appropriation for the improvement having been made by the River and Harbor Act of August 30, 1852. The project was modified by subsequent River and Harbor Acts of March 3, 1881, September 19, 1890, June 3, 1896, and June 13, 1902. For further details, see page 1937 of Annual Report for 1915, and page 1453 of Annual Report for 1938. Existing project. This provides for an outer harbor or stilling basin formed by two breakwaters extending from the shore on either side of the mouth of the Manitowoc River 425 feet apart at their outer ends and diverging to a distance of about 2,325 feet apart at their inner ends, having lengths of 2,540 feet and 2,290 feet for the north and south breakwaters, respectively; for a channel 21 feet deep, extending from that depth in the lake through the outer harbor to the mouth of the river, a total length of about 2,500 feet, with a width of about 650 feet; for a channel 21 feet deep in Manitowoc River from the river mouth to the second rail- way bridge, a distance of approximately 1.7 miles, with widths of 180 feet at the mouth, reducing to 150 feet at the upper end, with intermediate reductions and enlargements; for removal of old north stub pier at the river entrance; and for dredging in the outer harbor an approach channel 21 feet deep to a proposed city ter- minal on the lake front south of the shore end of the south break- water. The breakwaters are formed of stone-filled timber cribs, concrete caissons, and piling, all of which are capped with concrete superstructures. The project depth is referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York.

The act of August 30, 1935, provided that the work of dredging an approach channel to the proposed city terminal in the outer harbor "shall not be undertaken until local interests shall have submitted assurances satisfactory to the Secre- tary of War that such terminal will be constructed." The plan for the municipal terminal has been abandoned. All other requirements have been complied with. Terminal facilities. There are 3 car ferry slips, 2 grain eleva- tors, 2 shipbuilding yards, and several wharves used for handling coal, building materials, cement, and miscellaneous commodities. While these facilities are considered fairly adequate for existing commerce, it is believed the city should provide a suitable wharf with warehouse and railway connection, which should be open to the general public. Operations and results during fiscal year. Condition surveys were made by hired labor and use of Government plant at a cost of $2,427. Preliminary engineering in connection with re- pairs to breakwater was performed at a cost of $447. Total maintenance costs were $2,874. Condition at end of fiscal year. The existing project is about 87 percent complete. The work remaining to be done consists of dredging the approach channel in the outer harbor, which is not now desired by local interests. The breakwaters completed in 1910 are in generally good condition, except at the outer ends which require repairs. The dredging of the channel through the outer basin to existing project depth, and the removal of a portion of the old north stub pier at the river entrance were commenced in May 1937, and completed in December 1937. Dredging of the river channel was commenced in June 1939, and completed in July 1942. The controlling depth for practicable widths at low 1238 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The act of September 3, 1954, provides that no dredging in the inner harbor shall be accomplished until local interests agree to (a) hold and save the United States free from damages due to construction and maintenance of the improvement, and (b) make available an adequate area to locate the transfer facilities required for unloading bulk-petroleum carriers. Local interests were notified of the required conditions on September 7, 1955, and requested to furnish assurances. The City Council of Sheboygan by special resolution on February 18, 1956, assured the Government that they would hold and save the United States free from damages due to the construction and maintenance of the improvement; and the Wisconsin Oil Refinery Company has as- sured that an adequate area will be made available for unloading bulk-petroleum carriers. Both of the above assurances were accepted on March 1, 1956. Terminal facilities. These consist of four wharves used for handling coal, building material, fish, and miscellaneous commodi- ties. The city has provided a public wharf. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work. The United States dipper dredge Kewaunee, during the period 26 June to 19 November 1956, removed 433,505 cubic yards of material at a cost of $192,390.

ARMY, 1957 foot above or below the annual mean stage and extreme fluctua- tions of temporary nature, due to wind and barometric pressure, of about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work (1957) is $4,995,000, exclu- sive of the amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $241,400. Local cooperation. The act of August 30, 1935 provided that the original dredging of the outer harbor area be done by the city of Milwaukee and the city of Milwaukee be reimbursed at actual cost but not to exceed 10 cents per cubic yard, place measurement, for original dredging done subsequent to the authorization of the work by Congress. Agreement covering the dredging was exe- cuted by the Secretary of War February 23, 1934, after this work was originally authorized as part of the Public Works program. All other requirements have been complied with. The act of March 2, 1945 required that no dredging shall be done by the United States until local interests have released the Govern- ment, in a manner satisfactory to the Secretary of War, from all liability for damages to lands, revetments, structures, and suba- querous installations attributable to the dredging operations. Local interests were notified in April 1945, of the required conditions and requested to furnish assurances, that they will be met. The com- mon council of the city of Milwaukee, on October 15, 1945, adopted a resolution (No. 82734) releasing the Government from all lia- bility as required. This assurance was accepted and approved by the Secretary of War on April 8, 1946. Terminal facilities. There are four car ferry slips, and 56 other wharves, private and municipal, used for the handling of coal, grain, building materials, cement, petroleum products, and miscel- laneous commodities. As the facilities in the inner harbor are considered inadequate for existing commerce, the Milwaukee Harbor Commission is engaged in building an outer harbor. Operations and results during fiscal year. New work: A con- tract was awarded in June 1957 for maintenance and new work dredging in the Milwaukee, Menomonee, and Kinnickinnic Rivers and preliminary work in connection therewith was performed at a cost of $1220. Maintenance: Condition surveys and inspections were con- ducted by hired labor at a cost of $13,471. Work on the re- construction of 800 feet of the north breakwater was performed by contract at a cost of $231,328. Dredging in the Milwaukee, and Kinnickinnic Rivers was commenced by contract at a cost of $19,237. Work was performed in connection with reconstruc- tion of 400 feet of north breakwater at a cost of $67,012. Repairs to breakwater by hired labor and purchase of materials for future breakwater repairs were made at a cost of $90,176. Total maintenance costs were $421,224. Condition at end of fiscal year. The project in effect prior to the modifications of August 30, 1935, and March 2, 1945, was com- pleted in 1934. No work has been done on deepening the outer harbor area to 21 feet north of the inner entrance piers, nor on RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 1245 the last modification of the project providing for dredging the river channels to 21 feet deep. The north breakwater was com- pleted for a length of 8,210 feet in 1909. Construction of 1,744 feet in extension of the north breakwater was commenced in May 1924 and completed in August 1925, making the total length 9,954 feet. The north pier was completed in 1905 and con- struction of the south pier was commenced in April 1909 and completed in November 1910. Construction of the south break- water and shore connection was commenced in May 1925 and completed in October 1929, except for placing additional riprap and rebuilding about 756 feet on the breakwater damaged by a storm of October 22-23, 1929. Rebuilding the damaged section of the south breakwater and placing of additional riprap were commenced in April 1931 and completed in August 1932. Dredg- ing for deepening and widening the entrance channel to existing project depth and width, was commenced in May 1929 and com- pleted in September 1930. Placing additional small stone around the caisson breakwaters to chink the voids in the large riprap was commenced in 1930 and completed in 1934. Prior to the modification of August 30, 1935, the city of Milwaukee dredged the area in the outer harbor south of the inner entrance piers and lakeward of the pierhead line to more than 21 feet below datum without cost to the United States. The concrete superstructures and the timber crib sections of the north breakwater and the harbor piers are showing dis- integration and require repairs. The south breakwater and shore connections are in generally good condition. The controlling depth at low water datum at the close of the fiscal year was 21 feet and more in the entrance channel through the outer basin and between the inner piers; 21 to 19 feet in the Milwaukee River to Buffalo Street Bridge, and 18 feet to head of project; 20 feet in Kinnickinnic River to 100 feet upstream of C. and N. W. Railway bridge, and 19 feet to Kinnickinnic Avenue Bridge; and 20 feet in the Menomonee River to the 16th Street Bridge, and 20 to 15 feet to upper end of project. The costs under the existing project were $4,539,032 for new work, and $2,718,986 for maintenance, a total of $7,258,018.

CALUMET HARBOR AND RIVER ILL. AND IND. Location. Northeastern Illinois (Cook County), near the southern end of Lake Michigan, 121/2 miles south of Chicago Har- bor, and known on the Great Lakes as South Chicago Harbor, it being in the southerly part of and within the corporate limits of the city of Chicago, except for a part of the breakwaters and of the anchorage behind same, which are in Indiana. The Calumet River is within the Chicago city limits. (See United States Lake Survey Chart No. 755.) For description, see page 1471 of Annual Report .for 1932. Previous projects. The original project for Calumet Harbor was adopted by River and Harbor Act of July 11, 1870, and modi- fied August 11, 1888. Work was continued under these projects until 1896. The original project for Calumet River was adopted by River and Harbor Act of July 5, 1884, and modified August 5, 1886. For further details, see page 1943 of Annual Report for 1915, and page 1515 of Annual Report for 1938. Existing project. This provides for the following work: a. For an outer harbor protected by a breakwater extending eastward from the shore about 4,400 feet and thence southeasterly about 8,100 feet to the harbor entrance. b.

For widening and straightening the river channel, except through the rock cut, to within 20 feet of bulkhead lines now or hereafter established. 1258 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 g. For five turning basins spaced along the river channel, of suit- able size for turning the largest lake cargo vessels, and each of the same depth as the adjacent channel. The project depths are referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. Fluctuations in stage of the river are practically those resulting from changes of water level in Lake Michigan. On Lake Michi- gan, seasonal fluctuations in mean stage from low water in winter to high water in summer average about 1.2 feet. Local and tem- porary fluctuations of 0.1 to 0.5 foot, due to wind and difference in barometric pressures, occur daily. Seiches of 3 to 4 feet occur at infrequent intervals. The estimate of cost for new work, revised in (1957) is $12,827,000, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $101,400.

Local cooperation. The act of March 3, 1905, required, as a condition precedent to Federal expenditures upon any one of the five turning basins, the donation to the United States of the land necessary for that turning basin. As a result, the land needed for turning basins 1, 3, and 5 was conveyed to the United States. The total area thus conveyed is 17.8 acres, and the value of the land at the time of its conveyance was approximately $35,700. The act of August 30, 1935, provided that the widening of the channel at any locality, or the future excavation of a turning basin, shall not be commenced until local interests have furnished, free of cost to the United States, the lands or easements necessary for such widening or excavation, and have either provided any neces- sary bulkheads, or have released the United States from all damages to adjacent lands by reason of the excavation. The Republic Steel Corp. has dredged a new turning basin on the east side of the Calumet River just north of 122d Street, to replace the original turning basin 3, and has constructed a bulk- head along the channel side of the original basin 3, and reclaimed the area to provide land for plant expansion. The corporation has RIVERS AND HARBORS--CHICAGO, ILL., DISTRICT 1259 also built a bulkhead along two portions of the east side of the river between a point opposite the Semet-Solvay slip and the new turning basin 3, and has widened and deepened the east side of the rock section between the United States east channel line and its bulkhead. The United States has widened and deepened 3 portions on the east side of the river, and 2 portions on the west side of the river between 100th Street and turning .basin No. 3. Local interests donated the necessary land for the widening. Terminal facilities. There are 41 docks handling foreign over- seas, lake vessels, and river barge cargoes. The most important cargoes handled are iron ore, grain, coal, limestone, sand and gravel, iron and steel products, and miscellaneous package freight. There are two boatyards, one for repairs to large lake vessels (this yard has two large drydocks), and the other boatyard has one floating dry-dock for repairing and building commercial river craft. The United States Government owns one dock which is used by the Corps of Engineers only. There are no other publicly owned docks on the Calumet River, except for the one reserved for the exclusive use of the city of Chicago fireboat. Operations and results during fiscal year. New work: Dredg- ing by contract, adjacent to the Rail-to-Water Transfer Corpora- tion dock, was accomplished at a cost of $104,569. Total cost of new work was $104,569. Maintenance: Condition surveys and flue dust investigations were made at a cost of $45,926. Channel dredging by contract was accomplished at a cost of $32,882. Repairs to breakwaters were made by placement of 17,845 tons of stone protection at a cost of $158,293. Total maintenance costs were $237,101. Condition at end of fiscal year. The existing project is about 47 percent complete. The work remaining to be done to complete the project consists of the construction of turning basins 2 and 4; dredging portions of the outer harbor; deepening, and completing the widening, and straightening the Calumet River; dredging an approach channel to the harbor through the shoals outside the detached breakwater; anrid closing the gap between the break- waters. The timber crib breakwater (6,712 feet, completed in 1904; concrete superstructure completed in 1924) is in fair condi- tion. The cellular type steel-sheet pile breakwater (5,007 feet, completed in 1935) is in fair condition. Under permit from the Secretary of War, the Youngstown Sheet & Tube Co. and its pre- decessors have removed all of the south pier (completed in 1897) and replaced it with a concrete dock wall 2,961 feet in length and 50 feet southerly of the pier's original location. Under permits from the Department, the Defense Plant Corporation built two sections of bulkhead on the east side of the river between a point opposite the Semet-Solvay slip and the new turning basin 3 at mile 4.7. The United States has widened and deepened the chan- nel adjoining the new bulkhead except through the rock section, where the widening was done by the corporation. Depths in the outer harbor vary from 23 to 26 feet. Controlling nidchannel depth in the entrance channel is 25.2 feet. The controlling mid- channel depth in the river is about 17 feet, up to and including 1260 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 turning basin 5. Depths are based on soundings taken in Novem- ber and December 1956 and January 1957, and are referred to low water datum. The head of navigation for deep-draft vessels in the river is at turning basin 5 at the entrance to Lake Calumet. The total costs, all funds, to June 30, 1957, were $9,631,230, of which $6,594,627 was regular funds and $3,036,603 was Public Works funds; $5,973,421 being for new work and $3,657,809 for maintenance.

To provide for the 300-foot channel, a parcel of land (of about 4.6 acres), generally 100 feet wide, lying on the east side of the Calumet River Branch, commencing at the north side of 141st Street and extending northward toward The Forks 1262 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 for a distance of about 2,107 feet, has been conveyed to; and accepted by the United States. Local interests have also con- structed about 1,350 feet of bulkhead along the east side of the Calumet River Branch, and have reconstructed the bulkhead on the west side from The Forks to 141st Street. The Defense Plant Corporation has built a bulkhead along the east side of the canal between the Pennsylvania Railroad Co.'s bridge and Dickey Place Bridge; the United States has widened and deepened the east side of this portion of the widening. The Youngstown Sheet and Tube Co. has constructed a bulkhead along the west side of the canal between the Indiana Harbor Belt Railroad Co.'s bridge and the Pennsylvania Railroad Co.'s bridge, and the United States has widened and deepened the west side of this portion of the widening. All prior requirements have been fully complied with. Terminal facilities. There are 16 docks handling lake and river cargoes. The most important cargoes handled are iron ore, petroleum products, limestone, iron and steel products, sand and gravel, and coal. There are no public docks in this harbor. Operations and results during fiscal year. New work: Dredg- ing adjacent to the Youngstown Sheet & Tube Co. dock in the canal was accomplished by contract at a cost of $41,588. Contributed funds in amount of $2,518 were expended for preparation of plans and specifications for proposed modification of the northerly breakwater. Maintenance: Condition surveys and flue dust investigations were made at a cost of $30,187. Dredging in the canal was accom- plished by contract at a cost of $48,147. Upon completion of the work, the United States Steel Corp. reimbursed the United States in the amount of $63,000 for a portion of the dredging, accom- plished in fiscal years 1956 and 1957. Total maintenance costs were $15,334. Conditionat end of fiscal year. The existing project is about 80 percent complete. The work remaining to be done to complete the existing project consists of completing the widening of the main stem of the Indiana Harbor Canal to a bottom width of 260 feet, with a depth of 22 feet from the outer harbor to The Forks; com- pleting the widening of the Calumet River Branch from The Forks to 141st Street to the same width and depth, and completing the deepening and widening to full project dimensions of the upper 3,440 feet of the Lake George Branch. The rorth breakwater (rubblemound, 2,520 feet, completed in 1922) is in good condition. The east breakwater (concrete caisson, 1,507 feet, completed in 1926) and northerly extension (rubblemound, 2,324 feet, com- pleted in 1935) are in good condition. The controlling midchannel depths are as follows: 26 to 28 feet in the entrance channel parallel to the rubblemound breakwater and generally 23 to 26 feet in the outer harbor; 25 feet between the bulkheads of the steel companies to the five bridges; 22 feet from the five bridges to the turning basin at The Forks; from 20 feet at the entrance to 15 feet at a point 50 feet from the inner end of the turning basin east of Canal Street; 22 feet in the turning basin at The Forks; 22.0 feet from the turning basin at The Forks to 1,300 feet below the RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 1263 141st Street Bridge and thence 16 feet to 100 feet below the 141st Street Bridge; and 22.0 feet from the turning basin to 800 feet above the Indianapolis Boulevard Bridge on the Lake George Branch. Depths are referred to low-water datum. The head of navigation for commercial vessels is at the Baltimore & Ohio terminal railroad bridge on the Lake George Branch, about 3 miles from the outer harbor, and at a point about 2,200 feet from The Forks on the Calumet River Branch, about 2.5 miles from the outer harbor. The total costs of the existing project to June 30, 1957, all funds, were $6,014,839, of which $4,387,004 was regular funds, $1,618,044 public works funds, and $9,791 contributed funds; $3,680,567 being for new work and $2,334,272 for maintenance.

Operations and results during fiscal year. Condition surveys, inspections and reports, were performed by hired labor at a cost of $3,360. Dredging was performed by the U. S. dipper dredge Kewaunee and the U. S. bucket dredge Winneconne during the periods August 21 to November 10, 1956 and November 20 to December 10, 1956 at a cost of $100,436. The total costs for the fiscal year were $103,796, all maintenance. RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 1265 Condition at end of fiscal year. The existing project was com- pleted in December 1936. Concrete superstructure, 1,304 feet, on the detached breakwater, completed in 1925, is in fair condition, and the entrance piers, completed in 1931, are in good condition. Under permit from the Secretary of War, the Northern Indiana Public Service Co. has removed 615 feet of the inner end of the west pier and about 719 feet of the bulkhead south of the pier, and has replaced them with a steel-sheet pile bulkhead located land- ward of the former dock lines. The area channelward of the new bulkhead was dredged by the permittee to 18 feet. Depths in the entrance channel up to the Franklin Street Bridge vary from 9 to 25 feet. Between the Franklin Street Bridge and the turning basin at the head of the project, the depths vary from 1.0 to 15.0 feet in a channel about 60 feet wide, except in the draws of the Michigan Central Railroad Co.'s bridge where the width is about 40 feet. The turning basin at the head of the project has shoaled above datum. Available anchorage depths in the basin are 12 feet in the northerly portion and 8 feet in the southerly portion. Depths are referred to low water datum. The head of navigation for commercial vessels is the turning basin at the head of the project, 1.04 miles above the outer end of the west pier. Above this point, depths are only sufficient for small launches. The total costs of the existing project to June 30, 1957 were $2,771,576, of which $1,212,385 was for new work and $1,559,191 for maintenance.

Local cooperation. The River and Harbor Act of January 21, 1927, modified the existing project subject to the condition that the State of Illinois transfer to the United States without cost all rights and titles in the two State-owned dams on the Illinois River, and that local interests furnish the United States without cost all necessary areas for the disposal of materials dredged in creating and maintaining the channel authorized (S. Doc. 130, 69th Cong., 1st sess.). By deed dated March 28, 1928, the State of Illinois transferred these locks and dams to the United States. Permission has been granted by many riparian landowners for use of their lands for the disposal of dredged material. The River and Harbor Act of July 3, 1930, modified the exist- ing project subject to the following provisions: That the project thus adopted shall be in all its parts a navigable waterway of the United States, forever free to the public use of all, unen- cumbered by any tolls or restrictions of any kind whatsoever except such as may be imposed by Congress; that the State of Illinois shall proceed, subject to the supervision and approval of all expenditures and obligations by the Secretary of the Army, to construct the highway bridges at Brandon Road and Marseilles Canal, to make the necessary alterations in other highway bridges across the Illinois Waterway, to make the necessary arrangements and agreements for the alterations of the railroad bridges across said waterway, and to do such other work on said waterway as the Secretary of the Army shall direct and the available funds of the State make possible, the bridges mentioned not to become the property of the United States, and no obligations to be incurred by the United States to maintain, operate, or replace them; and that no claim shall lie against the United States because of any contractual obligations which have been or may be entered into by the State of Illinois as regards the construction of a waterway between Utica and Lake Michigan (S.

RIVERS AND HARBORS-CHICAGO, ILL, DISTRICT 127.1 The State of Illinois appropriated $20,000,000 for the construc- tion of a waterway providing minimum 8-foot depths in channels not less than 150 feet wide, from the upper end of the Federal project on the Illinois River, to Lockport. The lock and, dam at Starved Rock was about 95 percent complete, the Marseilles lock was about 95 percent, the Marseilles Canal 98 percent, Dresden Island lock and dam about 20 percent, Brandon Road lock and dam about 70 percent, and the Lockport lock about 95 percent com- plete, before the passage of the River and Harbor Act of July 3, 1930. The River and Harbor Act of August 30, 1935, as modified by the River and Harbor Act of June 20, 1938, provides that local interests furnish to the United States, free of cost, all necessary land to effect the improvements recommended in House Document 180, 73d Congress, 2d session, and install. operating machinery - and place in operating condition the three drawbridges across the Chicago Sanitary and Ship Canal between its junction with the Calumet-Sag Channel .and Lockport when directed by the Secretary of the Army. All requirements have been met except for the installation of operating machinery in the Atchison, Topeka & Santa Fe Railway bridge at Lemont, Ill. The River and Harbor Act of July 24, 1946, superseded the provisions of River and Harbor Act of March 2, 1945, and pro- vided that local interests furnish free of cost to the United States all lands, easements and rights-of-way, and spoil-disposal areas necessary for the new work and for subsequent maintenance when and as required, including the alteration of utilities as necessary, with the exception of such land needed for the waterway as is now occupied by abutments or railroad tracks at the approaches to railroad bridges; and agree to remove at their own expense, or satisfactorily alter, the highway bridges across Des Paines River at McDonough and Cass Streets (Joliet) across the Chicago Sani- tary and Ship Canal. at 16th Street (Lockport), Romeo Road, and Lemont Road, and all highway and street bridges across the channels included in the project lakeward. of Sag Junction Which,, in the opinion of the Secretary of the Army, constitute unreason- able obstructions to navigation; construct all necessary new high- way, street, or foot bridges across these channels; agree to pro- vide near Clark Street, Gary, Ind., an adequate public barge-rail- truck terminal open to all on equal terms; and that the several sections of the proposed channel may be improved as separate units when considered advisable by the Secretary of the Army and the Chief of Engineers after local interests have provided, or furnished assurances satisfactory to the Secretary of the Army that they will provide the cooperation required for any unit. The city of Chicago has supplied informal assurances that it will furnish the lands between 130th and 138th Streets for the Calumet River lock site and appurtenances. The following formal assurances have been accepted: a. Resolution adopted by the Board of Trustees of the Sanitary District of Chicago on May 9, 1955, furnishing ,assurance that easements would be granted through its lands on the south side 1272 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of the channel from 96th Avenue to the controlling works foot bridge east of Blue Island and also an easement through the right-of-way on the north side of said channel in the vicinity of Blue Island; also the Sanitary District would use its efforts and offices to effect relocation of all utility lines from 96th Avenue to the foot bridge east of Blue Island and remove the bridges at Kean Avenue, 86th Avenue, Homan Avenue and Francisco Avenue. b. Resolution adopted by the Board of Trustees of the Metro- politan Sanitary District of Greater Chicago on May 31, 1956, furnishing assurance that it will furnish all lands, easements, and rights-of-way and spoil-disposal areas necessary for the widening, construction and for subsequent maintenance of the Calumet-Sag Channel. The Sanitary District is presently engaged in the acqui- sition of the privately owned land required for spoil disposal and the funds appropriated are adequate to complete the recommended increment of the project. c. By letter dated May 4, 1955, from Hon. Daniel Ryan, presi- dent of the Board of Commissioners of Cook County, Ill. assurance was given that the Board of Commissioners will adopt a resolution pledging that Cook County will fulfill its obligation for the follow- ing bridges: Kean Avenue, 86th Avenue, Harlem Avenue, Ridge- land Avenue, 127th Street, Kedzie Avenue, and Western Avenue. Formal resolution was adopted by the Board in July 1956. d. By letter dated March 14, 1955, (accepted July 29, 1955) from Governor William G. Stratton of Illinois, assurances were given as follows: "The Sanitary District of Chicago has agreed to provide necessary ease- ments for right-of-way and spoil-disposal areas, to require alteration of utilities and to remove such bridges as are owned by the Sanitary District and which will no longer be needed. The Board of Commissioners of Cook County have programed four bridges and Mr. Ryan assured me that the Board of Commissioners of Cook County would take care of the bridges at Ridgeland Avenue and Francisco Avenue. The city of Chicago has agreed to rebuild the bridge at Indiana Avenue. "Assurances have also been received from the Forest Preserve District of Cook County to provide easements and spoil areas for that portion of the channel traversing forest preserve district property. "The State desires to cooperate to the fullest extent in advacing and pro- moting the Calumet-Sag project. The State will rebuild the bridge across the channel on 96th Avenue and will alter the bridge at Cicero Avenue to clearances required by the Corps of Engineers. The State will also support legislation to acquire approximately three hundred acres needed for spoil- disposal area now owned by private interest and assures the Federal Govern- ment that work required by local interests, including the bridges in Blue Island, will be performed within say a period of 5 years after an initial Federal appropriation is granted."

BEARDSTOWN, ILLINOIS RIVER, ILL. Location. Beardstown is located in Cass County, Ill., on the south bank of the Illinois River at river mile 89, about 70 miles below Peoria, Ill. Existing project. The project provides for construction of a new section of floodwall to replace that lost or damaged, and for raising, strengthening, and exteriding the remaining portion of the floodwall and adjacent levees, and the modification of existing levees in the adjacent Lost Creek, South of Beardstown, and Valley drainage and levee districts. The project when completed will afford flood protection to the city of Beardstown and adjacent land against the maximum flood of record, having an expectancy of once in 80 years. The project was authorized by the Flood Control Act approved May 17, 1950 (see H. Doc. 332, 81st Cong.). The estimated cost, revised in 1956, is $4,680,000 Federal costs; lands and damages, $50,000 non-Federal costs; total $4,730,000. Local cooperation. Local interests have indicated that require- ments will be met. All rights-of-way and easements required for construction of the floodwall have been furnished. Local interests are now negotiating for the required rights-of-way for the new levee construction and it is anticipated that assurances will be fully complied with by August 1, 1956. Operations and results during fiscal year. Surveys, explora- tions, tests, designs, and preparation of plans and specifications were conducted by hired labor. Construction of the Floodwall was initiated in December 1954 by continuing contract and com- pleted in November 1956. The total cost for the fiscal year was $128,126, of which $70,301 was for engineering and miscellaneous hired labor works, and $57,825 was for contract work on the Floodwall. Condition at end of fiscal year. The project is 29 percent com- plete. Preliminary planning was continued. Construction of the floodwall was completed. The work remaining to be done consists of completing reconstruction of the following levees, (1) Levees adjacent to Beardstown, (2) Lost Creek Levees, and (3) the South Beardstown and Valley District Levees.

The St. Marys River, a Great Lakes connecting channel, is about 63 miles long, and flows in a southeasterly direc- tion between the State of Michigan and the Province of Ontario, Canada, from the eastern end of Lake Superior into the northern end of Lake Huron. (See United States Lake Survey Chart Nos. 61, 62, and 63.) At Sault Ste. Marie, Mich., about 14 miles down- stream from Lake Superior, are located 4 parallel locks and a hydroelectric powerplant. Previous projects. Authorized by River and Harbor Acts of July 8, 1856, July 11, 1870, June 14, 1880, August 2, 1882, and 1285 1286 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 August 5, 1886. For further details, see page 1955, Annual Report for 1915, and page 1529, Annual Report for 1938. Existing project. This provides for channels through St. Marys River, which at low water datum are suitable for vessels drawing 25.5 feet, with a least channel width of 300 feet, and for chan- nels between Lake Superior and the falls having minimum widths of 1,000 feet and a depth of 30 feet below low water datum over Gros Cap and Point Iroquois Shoals and through Round Island Shoals and Middle Ground, and 28 feet through Vidal Shoals. The specific improvements include dredging shoals between the mouth of the river and Lake Munuscong; excavating channels from Lake Munuscong to Lake Nicolet on either side of Neebish Island, a distance via West Neebish of 14 miles and via Middle Neebish 15 miles, the Middle Neebish, or upbound, route to have a least width of 500 feet with a least depth of 21 feet in the easterly 200-foot width, and a least depth of 27 feet in the westerly 300-foot width, and the West Neebish, or downbound route to have a least width of 300-feet; widening and deepening the anchorage.area on the west side of the channel in Lake Nicolet to a maximum width of 1,000 feet over a length of 5,500 feet, with a depth of 28 feet for anchorage and maneuver; dredg- ing to widen and deepen the upper entrance channel into Lake Nicolet; dredging through shoals between the lower end of the canals and the upper entrance to Lake Nicolet, including ex- tension of anchorage and maneuver area below the locks and widening of the angle at black gas buoy No. 33; constructing compensating works at the falls; constructing remedial works at the inlet of the power canal of the Carbide Power Co.; deepening and widening the tailrace of the United States powerplant and construction of the first step (14,000 kilowatt capacity) of a new hydroelectric powerplant of 45,000 kilowatt ultimate capacity, constructing and operating 4 locks, 2 canals, and an emergency dam for each of the canals at the falls; including a new lock on site of Weitzel lock and replacement of Poe lock, deepening the approach channels and reconstruction of approach piers; widening and deepening the channels through Vidal Shoals; widening the channel from Point Louise. 1,000 feet and Brush Point to bottom width of 1,200 feet, widening the channel across Point Iroquois Shoals a maximum width of 1,500 to 5,300 feet as measured from the center line of Birch Point Range, with a depth of 29 feet for anchorage and maneuver. The following table shows the principal features of the locks and emergency dams. All structures are located at Sault Ste. Marie, Mich. The Poe lock was operated and maintained under the permanent indefinite appropriation from August 3, 1896, the Davis lock from October 21, 1914, and the Sabin lock from September 18, 1919, to the end of the fiscal year 1935. The original State locks were operated and maintained under the same appropriation from June 9, 1881, to November 2, 1886, after which they were destroyed by excavation for the present Poe lock.

Actual costs to June 30, 1957, $12,718,806. 9 Including engineering office, and inspection. 1o Not separable from cost of locks. Note. The limiting draft to the locks is determined by the depth over the breast walls. The Weitzel lock, destroyed in 1942 by excavation for the MacArthur lock, was operated and maintained under the same appropriation from September 1, 1881, to the end of the fiscal year 1935. The project depths are referred to low water datum for Lakes Superior and Huron, which are 601.6 and 578.5 feet respectively above mean tide at New York. Each year the St. Marys River rises and falls about 1 foot as measured by the monthly mean levels. During the navigation season the difference between the highest and lowest monthly mean levels above the locks, since 1871, has been about 4 feet, and below the locks, since 1903, about 4.3 feet. In addition to these changes in level, occasionally a considerable oscillation takes place within 2 or 3 hours, which is somewhat in the nature of a seiche; such changes amounting to over 5 feet have been known to occur within 3 hours. The estimate of cost for new work, revised in 1957, is $162,509,000, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $1,782,397. 1288 REPORT OF THE CHIEF OF ENGINEERS, U. S.

ST. CLAIR RIVER, MICH. Location. This river, a section of the Great Lakes connecting channels, is about 40 miles long and flows in a southerly direction from Lake Huron into Lake St. Clair. (See U. S. Lake Survey Chart No. 43.) Existing project. This provides for channels through the St. Clair River, which, at low water datum, are suitable for vessels drawing 25.5 feet. The project also provides for compensating works, consisting of a number (estimated at 31) of submerged rock sills, with crests 31 feet below datum. The project depths are referred to local low water datums which correspond to low water datums for Lakes Huron and St. Clair, which are 578.5 and 573.5 feet above mean tide at New York. The water level of this river fluctuates with the levels of the lakes above and below it, which during the course of each yer ar e subject to a consistent Seasonal rise and fall, the lowest stages prevailing 1294 REPORT OF THE CHIEF OF ENGINEERS, U.

Existing channel has depth of 27.3 feet. 2Cutoff channel may be constructed in Canada if determined to be feasible. At the head of St. Clair River, as measured by monthly mean levels, the water may rise and fall each year during the navigation season as much as 1.3 feet. Since 1900 the difference between the highest and lowest monthly mean level during the navigation season has been about 4.5 feet. Occasional fluctuations due to winds of high velocity may be as much as 3.5 feet in 6 hours. The River and Harbor Act of July 24, 1946, approved the modi- fication of the project to provide for widening and deepening the Southeast Bend and improvement of the outlet of the North Chan- nel, St. Clair River, in general accordance with the following de- scriptions: (a) That the two-way channel at Southeast Bend, St. Clair River, from light 12 to St. Clair Flats Canal, be widened to a width of 700 to 800 feet, with a depth of 26 feet for 24-foot navigation; (b) that the North Channel outlet at the mouth of the St. Clair River be widened to provide a channel 100 feet wide and 10 feet deep from lower St. Clair River to Lake St. Clair, for small craft apart from the regular steamboat channels. The Act'approved March 21, 1956, provides for a project safe draft of 25.5 feet over the full width of the downbound and two- way channels when the levels of Lakes Huron and St. Clair are at their respective low water datums; except that a cutoff channel may be constructed in Canada at Southeast Bend, generally in accordance with the alternate plan of the District Engineer for that section and with such modification thereof as in the discretion of the Chief of Engineers is advisable, in lieu of further improve- ment along the existing alinement, if prior to the initiation of con- struction in this reach accomplishment of the cutoff is found to be feasible; at an estimated additional cost to the United States of $6,000,000 for new work and $10,000 annually for maintenance. RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1295 The estimate of cost for new work, revised in 1957, is $25,083,000. The average annual maintenance cost during the past 5 years was $55,084. The project feature for construction of the compensating works consisting of submerged rock sills is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this feature was last revised in 1954 and was estimated to be $10,600,000, for construction. No expense of maintenance will probably be required for the submerged sills.

Lake St. Clair, a section of the Great Lakes connect- ing channels, is located at the easterly limit of Detroit,' Mich. This lake is an expansive shallow basin having a steamer track length of about 18 miles from the mouth of the St. Clair River to the head of the Detroit River. (See United States Lake Survey Chart No. 42.) Previous projects. Authorized by River and Harbor Acts of August 30, 1852, March 2, 1867, and March 3, 1878. For further RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1297 details, see page 2882, Annual Report for 1896; pages 1957-1958, Annual Report for 1915, and page 1539, Annual Report for 1938. Existing project. This provides for a channel across Lake St. Clair which, at low-water datum, is suitable for vessels drawing 25.5 feet. The works authorized include a channel 700 feet wide and 27.5 feet deep from the mouth of the south channel of the St. Clair River to the open channel in Lake St. Clair, thence increas- ing to 800 feet width for the same depth in a length of about 2 miles and maintaining such channel dimensions across Lake St. Clair to the head of Detroit River, and a stone riprapped earth dike, 7,221 feet long, on the east side of the mouth of the south channel of St. Clair River. The project depth is referred to low water datum for Lake St. Clair, which is 573.5 feet above mean tide at New York. As measured by monthly mean levels, the water may rise and fall during the navigation season each year as much as 1.4 feet. Since 1860 the difference between the highest and lowest monthly mean level during the navigation season has been about 4.5 feet. Occa- sional fluctuations due to winds of high velocity may be as much as 1 foot in 6 hours. The estimate of cost for new work, revised in 1957, is $8,357,000, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $18,988.

S. ARMY, 1957 The project depths are referred to local low-water datum planes which correspond to low water datum for Lakes St. Clair and Erie and are taken at 573.5 and 570.5 feet, respectively, above mean tide at New York. Each year during the navigation season the river rises and falls about 2 feet as measured by the monthly mean levels. Since 1906 the difference between the highest and lowest monthly mean level during the navigation season has been about 4.0 feet. Occasional fluctuations in depths of several feet, produced by high easterly or westerly winds, respectively, raise or lower the water level at the west end of Lake Erie, and similarly affect the level of the lower Detroit River; such changes have been as much as 6 feet within 8 hours. The estimate of cost for new work, revised in 1957, exclusive of amounts expended on previous projects, is $76,238,000. The average annual maintenance cost during the past 5 years was $226,073.

Local cooperation. Fully complied with for completed portions of project. For the American channel north of Belle Isle as authorized by the Act of 1945, local interests are required to fur- nish free of cost to the United States, suitable spoil-disposal areas for new work and subsequent maintenance when and as required, RIVERS AND HIIARBORS-DETROIT, MICH., DISTRICT 1301 and hold and save the United States free from claims for damages resulting from the improvement. For the Trenton Channel modification approved May 17, 1950, responsible local agencies are required to give assurances satisfactory to the Secretary of. the Army that they will furnish without cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas necessary for the construction and subsequent maintenance of the project, when and as required; and hold and save the United States free from damages due to the construction and subsequent maintenance of the works. No local cooperation is required in connection with the modifications authorized by the Acts of July 24, 1946 and March 21, 1956. Terminal facilities. Within the limits of the port of Detroit are more than 8.4 linear miles of docks fronting on the river. A number of docks are owned by railroads and large manufacturing corporations over which no freight is received except for their own use. Other docks are owned by steamship lines, where preference is given to their own vessels. There are, however, still other docks that are open to the use of all vessels upon equal terms including one with terminal warehouse. Present terminals are considered adequate for existing commerce. Operations and results during fiscal year. Regular funds. New work: Deepening of the Amherstburg Channel was com- menced under three separate continuing contracts. The principal features of this work are the excavation of ledge rock and over- burden and the construction of compensating dikes. The work is scheduled for completion on June 30, 1960. Total costs during the fiscal year for new work were $1,115,719. Maintenance: Condi- tion surveys were made over the channel passing east of the Detroit River Light and Lower Livingstone Channel in July and August 1956 and June 1957 at a cost of $32,132. Revisory survey costs applied to U.S. Lake Survey operations were $2,342. The cost of supervision and administration of the project was $2,314. The location and removal of obstructions above 21-foot depth in the Amherstburg Channel and above 26-foot depth in the Living- stone Channel, a total channel length of about 8 miles, were ac- complished by sweeping survey and U. S. derrick boat Huron operation at a cost of $37,582. Repairs were made to the Sugar Island compensating dike by Government plant and hired labor at a cost of $7,128. The U. S. hopper dredge Hains operated in Lower Livingstone Channel and the channel passing east of the Detroit River Light during the period of August 25 to September 26, 1957, removing 266,724 cubic yards, bin measure, of shoal material at a cost of $69,916. Total costs for maintenance during this fiscal year were $151,414. Condition at end of fiscal year. The project in effect prior to the modifications of March 21, 1956, with the exception of the channel north of Belle Isle, deepening the westerly 300 feet of the Amherstburg Channel and the Ballards Reef Channel (south of its junction with the Livingstone Channel), and extenfd the turning basin in Trentorn Channel, was completed in 1'94". he 1302 REPORT OF THE CHIEF OF ENGINEERS, U.

ARMY, 1957 Terminal facilities. The wharves are located at the city of Holland, at the inner end of Lake Macatawa, and are used for handling coal, building materials, petroleum products, and miscel- laneous commodities. Two shipbuilding yards are located on the south shore of Lake Macatawa. The city of Holland has provided a public wharf for small craft. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: A con- struction contract for dredging a channel in Black River, widen- ing its junction at the turning basin was commenced on March 4, 1957. During the fiscal year, 160,000 cubic yards of material was dredged. The contract was about 67 percent complete at the end of the fiscal year, with completion scheduled for November 1957. Total costs during the fiscal year for new work were $109,610. Maintenance: Condition surveys were made during March 1957 at a cost of $2,742. Revisory survey costs applied to U. S. Lake Survey operations were $1,802. The U. S. hopper dredge Hains operated in the entrance channel during the period of April 4-9, 1957, removing 32,253 cubic yards, bin measure, of shoal material at a cost of $14,158. Advance planning and design for future re- construction of 493 linear feet of the north pier was accomplished at a cost of $864. The cost for supervision and administration of the project was $374. Total costs for maintenance during this fiscal year were $19,940. Condition at end of fiscal year. The existing project with the exception of the modifications authorized by the act of September 3, 1954, was completed in 1938. The breakwaters, piers, and re- vetments completed in 1910 are in generally good condition except that portions of the north pier and revetment require repairs. Dredging of the entrance channel to existing project depth, and the channel and turning basin in Lake Macatawa was commenced in May 1938, and completed in October 1938. The controlling depths at low water datum at the close of the fiscal year were 22 feet in the channel to Lake Macatawa, 21 feet in the inner channel in Lake Macatawa to the wharves at Holland, and 18 feet in the turning basin.

GRAND HAVEN HARBOR AND GRAND RIVER, MICH. Location. This harbor is on the east shore of Lake Michigan, about 108 miles northeasterly from Chicago and about 23 miles northerly from Holland. The river rises in Jackson County, Mich., and flows in a general westerly direction into Lake Michi- gan, with a total length of about 260 miles. (See United States Lake Survey Chart No. 765, and U. S. Geological Survey Grand Rapids quadrangle.) Previous projects. The original project for the river was adopted by the River and Harbor Act of March 3, 1881. A new project was adopted by the River and Harbor Act of June 3, 1896, and was modified by the River and Harbor Act of June 13, 1902. For further details, see page 1949 of Annual Report for 1915, and page 1481 of Annual Report for 1938. Existing project. This provides for protecting the mouth of the river by piers and revetments, 415 feet apart at the entrance diminishing to 390 feet inside, about 3,569 and 5,549 feet in length for the north and south sides, respectively, and for a channel 23 feet deep and generally 300 feet wide and 1,500 feet lohg from that depth in the lake to a point about 1,000 feet inside the pier ends; thence 21 feet deep and 300 feet wide and 11/4 miles long to the car-ferry slip, with an enlargement at the upper end; thence 21 feet deep and 300 feet wide and 11/4 miles long from the car- ferry slip to the Grand Trunk Railway bridge at Ferrysburg; with a turning basin 18 feet deep on the south side of the channel just below that bridge; thence a channel 18 feet deep and generally 100 feet wide to deep water in Spring Lake, a distance of about 1,350 feet in the river and about 1,750 feet up the outlet from Spring Lake; and for a channel in Grand River 8 feet deep at low water 1314 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 datum, 100 feet wide and 141/2 miles long to Bass River, the total length of river channel being about 171/ miles. The piers and revetments are built of stone-filled timber cribs and piling, all of which are capped with concrete superstructure. The project depths are referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level in the harbor are seasonal changes of about one-half foot above or below the annual mean stage, and extreme fluctuations of a temporary nature, due to wind and barometric pressure of about 11/ feet above or below the mean lake level prevailing at the time. The estimate of cost of new work, revised in 1954, is $964,800, exclusive of amounts expended on previous projects. The dredg- ing on the northerly side of the inner channel is considered to be inactive and is excluded from the foregoing estimate. The cost of this portion of the project, revised in 1954, was estimated to be $38,600. The average annual maintenance cost during the past 5 years was $250,307.

Condition surveys were made over the entire project channels during March and April 1957 at a cost of $10,937. Revisory survey costs applied to U. S. Lake Survey operations were $2,703. The U. S. bucket dredge Tompkins and the U. S. hydraulic dredge Depoe Bay opera- ted in the Grand River channel during the periods of October 10-21, 1956, and July 1 through September 7, 1956, respectively, removing 9,946 cubic yards, scow measure and 91,100 cubic yards, place measure, respectively, of shoal material at a cost of $72,249. The U. S. hopper dredge Hains operated in the harbor entrance and river channel upstream to the car-ferry dock during the period of April 10-29, 1957, removing 88,245 cubic yards, bin measure, RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1315 of shoal material at a cost of $34,425. Work under contract for reconstruction of 854 linear feet of the south pier was initiated in April 1957 and was still in progress June 30, 1957, at a cost of $165,682. Preliminary work for reconstruction of 605 linear feet of the north pier was accomplished at a cost of $57. The costs for administration and supervision of the project were $997. The total costs for maintenance this fiscal year were $287,050. Condition at end of fiscal year. The existing project is com- plete except for a small amount of dredging on the northerly side of the inner channel at the point of land 1,350 feet upstream from the inner end of the north revetment. This dredging cannot be done without revetting the bank"or endangering private cottages. The present channel past this site, having a least width of 240 feet, is considered adequate for present and reasonably prospec- tive commerce. The piers and revetments were completed in 1893 and are in fair condition except that a portion of the old timber crib piers requires repairs. Dredging of that portion of the channel between the car-ferry slip and the Grand Trunk Rail- way bridge to a width of 200 feet was commenced in August 1930, and completed in October 1930. Dredging of the river above the railway bridge to Bass River to existing project depth was com- menced in April 1931 and completed in June 1931. Dredging the channel into Spring Lake was commenced in September 1938 and completed in November 1938. Widening of the channel between the car-ferry slip and the Grand Trunk Railway bridge to 300 feet and dredging the turning basin on the south side of the channel just below that bridge were commenced in October 1948 and completed in September 1949. The controlling depths at low water datum at the close of the fiscal year were 23 feet at the entrance; thence 21 feet between the piers and in the river to the Grand Trunk Railway bridge, and 18 feet in the turning basin, and thence 8 feet to Bass River and 17 feet in the outlet from Spring Lake.

ARMY, 1957 The cost of new work for the completed project was $1,036,086, exclusive of amount expended on previous project. The average annual maintenance cost during the past 5 years was $121,202. Local cooperation. None required. Terminal facilities. In addition to the main terminal of the Pere Marquette Railway Co., consisting of three car-ferry slips and a wharf with warehouses, there are several wharfs used for handling coal, building materials, and miscellaneous commodities. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. Condition surveys were made over the entire project during April 1957 at a cost of $3,539. Revisory survey costs applied to U. S. Lake Survey operations were $1,802. The contract for reconstruction of 600 feet of south breakwater was initiated and is still in progress June 30, 1957, at a cost of $1,132. The cost of supervision and administration of the project was $425. The U. S. hopper dredge Hains operated in the entrance and river channel during the periods of May 7-9, 1957, and May 17-19, 1957, removing 19,330 cubic yards, bin measure, of shoal material at a cost of $9,809. Total costs for maintenance during the fiscal year were $16,707. Condition at end of fiscal year. The existing project was com- pleted in 1918. Construction of the breakwaters was commenced in 1908 and completed in May 1911. The construction of the shore connections was commenced in 1912 and completed in November 1894.: The dredging was completed in 1917, and the placing of ad- ditiona stone as riprap in 1918. The breakwaters and shore con- nections and the inner piers and revetments are in generally good cozidition except that the outer end of the north pier and a portion of the south shore connection substructure are in poor condition and require repairs. The outer 100 feet of the south breakwater were removed by private interests in 1939, by authority of the Chief of Engineers dated June 2, 1939, thereby increasing the width between the outer ends of the breakwaters to 475 feet. The south breakwater is therefore maintained for only a length of about 1,700 feet. The controlling depths at low water datum at the close of the fiscal year were 26 feet at harbor entrance, thence decreasing through the outer basin to 19 feet at lakeward end of the inner piers and in the channel between the inner piers and revetments to Pere Marquette Lake.

The project also provides for a south breakwater having a main arm 1,300 feet long and a shore connection 1,185 feet long, north pier and revet- ment 2,797 feet long, and south pier and revetment 770 feet long. The breakwater, shore connection, and north pier are built of stone-filled timber cribs and piling and are capped with concrete superstructure. The south pier and revetment consist of steel sheet piling with stonefill in pier. The project depths are referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage, and extreme fluctuations of a temporary nature, due to wind and barometric pressure, of about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work, revised in 1954, is $745,800, exclusive of amount expended on previous projects. The dredging of the river from near the Maple Street Highway Bridge to Manistee Lake portion of the project is considered to be inactive, and isexcluded from the foregoing cost estimate. The cost of this portion was last revised in 1954, and was estimated to be $16,500. The average annual maintenance cost during the past 5 years was $27,566. Local cooperation. The act of July 3, 1930 provided "that no work shall be undertaken on the section of the river through and above the bridges until they have been modified in a manner satisfactory to the Secretary of War." The Smith Street Bridge and the railroad bridge have been rebuilt, but the Maple Street Highway Bridge has not been modified as required. All other requirements have been complied with. 1324 REPORT OF THE CHIEF OF ENGINEERS, U. S.

The Inland Route, consisting of a series of intercon- nected lakes and streams in the northern tip of the Lower Peninsula of Michigan, extends from Conway at the western end of Crooked Lake near the shore of Lake Michigan, to Cheboygan at the Lake Huron end of the Straits of Mackinac, a distance of about 35 miles. Crooked and Indian Rivers are connecting channels in the waterway. Existing project. This provides for ,improvement of Crooked and Indian Rivers, Mich., and connecting lakes and channels to provide a channel 5 feet deep below the surface of the water when Crooked Lake, Burt Lake, and Mullet Lake are at low water datum, and generally. 30 feet wide with necessary widening at the bends, from Conway at the west end of Crooked Lake to the navigation lock in Cheboygan River with suitable jetties at the head of Indian River, and in Pickerel Channel from Pickerel Lake to Crooked Lake. The estimated cost for new work, revised in 1957, is $320,000, excluding $85,000 to be contributed by local interests. The existing project was authorized by the River and Harbor Act approved September 3, 1954 (H. Doc. 142, 82d Cong., 1st sess.). This document contains the latest published map. Local cooperation. Fully complied with including cash contribution of $85,000. Terminal facilities. No facilities for the transfer of freight exist along the Crooked and Indian Rivers, as the streams have RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1381. carried no freight tonnage for many years. Numerous small privately owned timber piers and wharves, some equipped with covered boat wells for servicing and storing recreational craft, have been constructed along the waterway. Landings maintained by hotel and resort operators are available to the public without charge for transfer of passengers. Public docks are located at Conway and Oden on Crooked Lake, the village of Indian River, Topinabee, and Mullet Lake Village on Mullet Lake, and at Cheboygan. Approximately 30 highways dead end at the water's edge, permitting public access to the water for all kinds of marine activities. Existing dock facilities are considered adequate for present and reasonably prospective traffic.

Seven small timber-pile docks are used primarily as fishing terminals by their owners. Ample space for mooring small craft is available along the face of old cribbing, and present terminals are considered adequate for all existing or reasonably prospective commerce. Operations nd results during fiscal year. Condition surveys were made over the entire project during June 1957 at a cost of $2,115. Advance planning for future reconstruction was initiated at a cost of $1,133. Revisory survey costs applied to United States Lake Survey operations were $901.00. The contract for dredging- the channel and reconstruction of the jetties with steel sheet piling was initiated and is still in progress June 30, 1957. Cost for the work this fiscal year was, $185,109. An adjustment was made in the cost of dredging completed in fiscal year 1956 and involved a reduction in costs of $1,345. Cost of supervision and administration of the project was $243. Total costs for maintenance during the fiscal year were $187,005. Condition at end of fiscal year. The existing project has not been constructed but the entrance channel" is being maintained under the previous project. The existing jetties have deteriorated to the point where they afford little or no protection from wave RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1335 action during storms and are ineffective in intercepting littoral drift from entering the channel. The controlling depth at the present time is about 3.5 feet below low water datum, from the State Highway Bridge through the entrance channel. The con- trolling depth could be reduced to about 3.0 feet in a very short period of time as a result of severe storm from either northeasterly or southeasterly direction.

S. ARMY, 1957 of the existing channel between the Court Street and Bristol Street Bridges; and for elimination from the authorized project, of the existing entrance channel in Saginaw Bay upon completion of the new entrance channel. The project depths are referred to low water datum for Lake Huron, which is taken at 578.5 feet above mean tide at New York. Due to storms, the level of the river at its mouth rises and falls about 3 feet. Spring freshets and excessive rains have caused an abnormal rise.of as much as 14 feet at Saginaw. Occasionally a considerable change takes place within a few hours, resulting from the raising or lowering of Saginaw Bay by violent winds. The estimate of cost for new work, revised in 1957, exclusive of amounts expended on previous projects, is $8,072,000. The average annual maintenance cost during the past 5 years was $88,420.

For further details, see page 1530 of Annual Report for 1932, and page 1558 of Annual Report for 1938. Existing project. This provides for the following: a. A channel 21 feet deep from that depth in Detroit River through the Short Cut Canal, 400 feet wide at the entrance, taper- ing to 200 feet in a distance of 2,000 feet, thence 200 feet to Maples Road, including a turning basin, 21 feet deep, near the upper end of the project. b. A channel 25 feet deep from that depth in Detroit River through the mouth of the old channel upstream for a distance of 1,300 feet, with a width of 240 feet at the mouth, tapering to 100 feet at a distance of 800 feet from the mouth, thence 18 feet deep and 100 feet wide for a distance of 1,425 feet, thence 17 feet deep and 100 feet wide to the Detroit, Toledo, & Ironton Railroad bridge, a distance of about 1,550 feet, thence 21 feet deep and 100 feet wide, flaring to 130 feet at the north end of the Peerless Portland Cement Co. wharf, thence 21 feet deep, with width flaring from 130 feet to 150 feet at the junction of the old channel with the Short Cut Canal, suitably widened at the bend opposite the Detroit Sulphite Pulp & Paper Co. plant. The distance from Detroit River to the head of the project at Maples Road is about 31/2 miles via the Short Cut Canal, and about 41/2 miles via the old channel. The project depths are referred to local low water datum in the Detroit River at the mouth of the Rouge River, which is 572.2 feet above mean tide at New York. The level of this river, except during floods, changes with the level of the Detroit River, which fluctuates to an average extent of about 1.5 feet during the navigation season. The estimate of cost for new work, revised in 1954, is $591,200 exclusive of amounts expended on previous projects. Except for dredging of the 25-foot channel to a distance 1,150 feet upstream of the mouth in the old channel, the work authorized in the act of August 30, 1935, is considered to be inactive and is excluded from the foregoing cost estimate. The cost of the inactive portion, revised in 1954, was estimated to be $657,800. The average annual maintenance cost during the past 5 years was $73,193. Recommended modifications of project. On March 16, 1954, the Chief of Engineers recommended modification of the existing project to provide in the Old Channel, from its junction with the Short Cut Canal to the north property limit of the Peerless Cement Corp., a channel 21 feet deep and 100 feet wide, widened to 150 feet at 2 bends, at an estimated cost to the United States of $101,500, which is $60,500 less than the amount presently 1340 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 authorized for this channel, with no change in the cost of annual maintenance over that now authorized. The recommended modification was submitted to Congress on October 19, 1956.

There is an iron ore dock near the river's mouth equipped with unloading machinery. The Ford Motor Co. has an ore and coal dock near the head of the river improve- ment, with improved type of unloaders. Eight docks fully equipped for handling oil and oil products, and one dock equipped for handling gypsum rock, have been constructed along the river- bank. These docks have good railroad connections. In addition, there are four docks owned by sand and gravel companies which have unloading machinery, and one pulpwood dock. There are 10 docks that receive coal, nine docks that receive stone, one dock that receives coal tar, and one dock that ships salt. There are also a number of smaller docks for launches. All docks along the river are privately owned and understood to be restricted to use of the owners. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. Condition surveys were made over the entire project during October 1956 at a cost of $4,681. Revisory survey costs applied to U. S. Lake Survey operations were $2,703. The cost of miscellaneous inspections and reports including supervision and administration was $544. The U. S. hopper dredge Hains operated over the entire project during the periods of July 23-25, 1956, and November 5 to December 29, 1956, removing 259,067 cubic yards, bin measure, of shoal material at a cost of $69,289. This cost was exclusive of the financial participation by industries (obtained as a result of studies on illegal deposit of industrial waste) in the following RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1341 amounts: Ford Motor Co., $11,405.00; Semet Solvay Co., $3,358.00; and Peerless Cement Co., $2,500.00. Total financial participation by industries during the fiscal year was $17,263. Total costs for maintenance during the fiscal year were $77,217. Condition at end of fiscal year. The 21-foot project, which consisted of dredging a 21-foot channel from the Detroit River via the Short Cut Canal to the upper limit of improvement and the construction of 5 dolphins at the mouth of the Short Cut Canal, was completed in 1923. The 25-foot project at the mouth of the old channel was started with funds from the Emergency Relief Administration, but due to shortage of funds, dredging was re- stricted to a distance of 1,150 feet upstream of the mouth of the old channel. All other work provided for in the act of August 30, 1935, relative to the improvement of the old channel, is held in abeyance until local interests have complied with the terms of local cooperation. The controlling depth of the 21-foot project, via the Short Cut Canal, is 21 feet along the center half of the channel to the turn- ing basin which has a controlling depth of 21 feet except along the channel banks. The controlling depth of the old channel, from its intersection with the Short Cut Canal to the 25-foot project, is- 17 feet. The 25-foot section has a controlling depth of 25 feet, except along the channel banks. All bridges have been altered to comply with the requirements of law. The dolphins at the mouth of the Short Cut Canal have been removed. The head of navigation is determined by a fixed bridge about 2,600 feet above the upper limit of improvement.

S.BARMYi 1157 26. MONROE HARBOR, MICH. Location. The harbor is on the lower reach of the Raisin River, which empties into Lake Erie at Monroe, Mich. (See United States Lake Survey Chart No. 3.) Existing project. This provides for a channel 21 feet deep and 300 feet wide in Lake Erie, a distance of about 15,800 feet; thence 21 feet deep and 200 feet wide, with necessary additional widths at bends, in Raisin River, for a distance of about 8,200 feet; thence 9 feet deep and 100 feet wide to the lower wharves at Monroe, a distance of about 3,800 feet. The project also provides for rip- rapping of protecting dikes on each side of the channel extending lakeward for a distance of about 1,200 feet; and for a turning basin with an area of about 22 acres and depth of 18 feet. The project depths are referred to low water datum for Lake Erie, which is 570.5 feet above mean tide at New York. The level of the river varies with that of Lake Erie, which fluctuates irregularly from year to year, the greatest annual fluctuation being about 2.75 feet and the least about 0.90 of a foot, measured by monthly mean levels. Since 1860, the difference between the highest and lowest monthly mean level during the navigation season has been about 4.9 feet. The cost for completed new work is $687,340, excluding $300,000 contributed by local interest. The average annual maintenance cost during the past five years was $11,240. The project feature for riprapping the protecting dikes is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this feature, revised in 1954, was estimated to be $90,000.

Condition surveys were made in the turning basin and outer channel during Septem- ber 1956 at a cost of $86. The cost of supervision and administra- tion of the project was $5. The U. S. hopper dredge Hains operated in a portion of the outer channel and turning basin RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 1343 during the period August 27 to September 25, 1956, removing 206,953 cubic yards, bin measure, of shoal material at a cost of $54,011. Total costs for maintenance during the fiscal year were $54,102. Condition at end of fiscal year. The existing project was completed in 1936, except for riprapping of protecting dikes on each side of the channel, which is not considered necessary at the (the present time. Due to the combined effect of severe storms and continued high water, dikes have largely disappeared. A sounding survey made in April 1956 indicates controlling depths of 14.5 feet through the center half of the channel. An after- dredging survey made in September 1956 indicates a controlling depth of 13.5 feet in the turning basin.

The Maumee River has its source in northern Indiana and empties into Lake Erie. The harbor is located at the westerly end of Lake Erie, 99 miles westerly frowtn Cleveland, Ohio. (See United States LakeiSurvey Chart No. 3.) Previous projects. Authorized by River anid Harbor Acts of June 23, 1866, June 14, 1880, July 5, 1884, August 5, 1886, July 13, 1892, and August 18, 1894. For further details, see page 1959 of Annual Report for 1915, and page 1565 of Annual Report for 1938: Existing project. This provides for a chnnel 25 feet deep and 500 feet wide from deep water in Lake Erie to the mouth of the Maumee River, with a width of 300 feet on each side of center dike in the bay channel; for a channel 25 feet deep in Maumee River to the Baltimore & Ohio Railroad dock, 400 feet wide from the mouth of the river to the Fassett Street Bridge, and 200 feet wide above that point; for a turning basin at the upper end, 18 feet deep and 8.25 acres in area; for a triangular widening at the bend in the channel at the mouth of the river, on the north side, of the channel opposite the Chesapeake & Ohio Railway dock, 3,055 feet in length, 460: feet maximum width and 16.2 acres in area; and for removal of the stone-revetted earth dike, foundation for range lights in Maumee Bay. ,1,000 feet long, forming a The project depths are referred to low water datum for Lake Erie, which is 570.5 feet above mean tide at New York. Ordinary fluctuations of water level are from 4 feet above to 2 feet below low water datum, and extreme fluctuations, produced by wind and other causes are from 9 feet above to 7.6 feet below that plane. The estimate of cost for new work, revised in 1957, is $6,206,000, exclusive of amounts expended on previous projects. The average annual maintenance cost during the past 5 years was $331,420.

On April 24, 1956, the Chief of Engineers recommended modification of the existing project to provide for widening the channel for an area of 22.4 acres and a depth of 25 feet opposite the Lakefront Dock at an estimated cost to the United States of $786,000 for construction and $6,200 annually for maintenance in addition to that now required, and for an area of 5 acres and a depth of 20 feet opposite RIVERS AND HARBORS--DETROIT, MICH., DISTRICT 1345 the American Shipbuilding Company at an estimated cost to the United States of $73,000 for construction and $1,500 annually for maintenance in addition to that now required. The recommended modification was submitted to Congress on June 7, 1956. Local cooperation. Fully complied with for completed portions of the project. For Widening at bend opposite Chesapeake & Ohio dock, approved May 17, 1950, and for removal of dike in Maumee Bay Channel, approved September 3, 1954, local interests are required to hold the United States free from damages resulting from the construction works. For the removal of the center dike, assurances of local cooperation furnished by the Toledo-Lucas County Port Authority were formally accepted for the United States as of November 30, 1956. Terminal facilities. There are three large railroad terminals for receipt of ore and five for handling coal, one fuel dock, four docks for handling grain, five docks for handling petroleum products, five sand and gravel docks, one cement dock, three private fish docks, and two package-freight terminals which are open to all vessels on equal terms. The terminal facilities are regarded as adequate for existing commerce. Operations and results during fiscal year. New work: A con- tract for the removal of the center dike in Maumee Bay, in the amount of $448,750 was commenced on June 3, 1957. The principal features of the work are removal and disposal of structures, reinforced and plain concrete, timber piling, framing and decking, rubble and earth. The project was 2.5 percent complete as of June 30, 1957. The contract completion date is November 22, 1957. Total costs during the fiscal year for new work were $3,595. Maintenance: Condition surveys were made over the project during July 1956, and May and June of 1957 at a cost of $23,118. Revisory survey costs applied to United States Lake :Survey operations were $2,703. The cost of miscellaneous inspections and reports, including supervision and maintenance of the project and custody of the harbor was $9,128. The cooperative stream-gaging program and hydroclimatic network studies were accomplished at a cost of $1,714. The U. S. hopper dredges Hoff/man, Hains, and Lyman operated in the Maumee Bay and River Channel during the periods of August 23 to December 22, 1956; September 26 to November 2, 1956; and November 26 to December 21, 1956; respectively. The total quantity of material removed by hopper dredge operations was 991,971 cubic yards, bin measure, of shoal material at a total cost of $345,211. Total costs for maintenance during the fiscal year were $381,874. Condition at end of fiscal year. The existing project, exclusive of widening the channel opposite the Chesapeake & Ohio Railway dock and removal of the center dike in Maumee Bay, was com- pleted in 1936. Maintenance dredging normally performed during the late summer and fall months usually restores project depth over a center width of 300 feet in the lake section and over about 80 percent pf the river channel.

This river drains an area of about 1,980 square miles in Hillsdale, Jackson, Calhoun, Eaton, Barry, Kalamazoo,: Van Buren, Allegan, Kent, and Ottawa Counties in southwestern FLOOD CONTROL-DETROIT, MICH., DISTRICT 1349 Michigan, and discharges into Lake Michigan about 2 miles down- stream from the village of Saugatuck. The city of Battle Creek is about 108 miles upstream from the mouth of the Kalamazoo River. (See United States Lake Survey Chart No. 76.) Existing project. This provides for flood protection along the Kalamazoo River at, and in the vicinity of, Battle Creek, Mich.,; to consist generally of excavation and clearing of the Battle Creek Channel to provide for an enlarged channel within the city of Battle Creek extending from above the Union Street Bridge downstream to its junction with the Kalamazoo River; rerouting the Kalamazoo River Channel in the vicinity of Liberty Street and Washington Avenue to bypass the constricted existing channel through the heart of the city; excavation and straightening the Kalamazoo River Channel downstream from the confluence of Battle Creek and the new rerouted Kalamazoo River Channel to below the Fort Custer Waterworks Bridge; riprapping or paving channels at critical locations in the new enlarged channels where the velocity of floodflows might be high enough to cause damage; constructing new and reinforcing existing highway and railroad bridges as required, and constructing a submerged weir and levees. The project is designed to provide protection for the city of Battle Creek from such peak flood discharges in the channels as would cause, when combined, a discharge of approximately 11,000 cubic feet per second below the confluence of Battle Creek and the Kalamazoo River. The estimated cost for new work, revised in 1957, is $6,170,000, excluding $155,000 to be contributed by local interests. The estimated cost to local interests, revised in 1957, is $3,093,000. The existing project was authorized by the Flood Control Act approved September 3, 1954 (S. Doc. 98, 83d Cong., 2d sess.). This document contains the latest published maps. Local cooperation. The Act of September 3, 1954, provides that no money shall be expended on the construction by the United States until responsible local interests have given assurances satis- factory to the Secretary of the Army that they will (a) provide without cost to the United States all lands, easements, and rights- of-way necessary for the construction of the project; (b) hold and save the United States free from damages due to the construction works; (c) maintain and operate all the works after completion, including supervision of maintenance and operation of the existing Monroe Street Dam and headrace on the Kalamazoo River, in ac- cordance with regulation prescribed by the Secretary of the Army; (d) prescribe and enforce regulations designed to prevent encroachments on the rights-of-way and improved channels; (e) construct new highway bridges across the new Kalamazoo River cutoff; (f) make all changes and additions to streets, water mains, electric powerlines, sewers, and other utilities necessitated by the improvements; and (g) contribute toward the project in accord- ance with the recommendation of the Secretary of the Army; and provided further that construction of the initial stage of the project as defined in the district engineer's report may be under- taken whenever funds are available and the prescribed local 1350 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 cooperation has been provided and whenever, in addition, local interests have agreed to remove, at their own expense concurrently with construction of the first-stage improvement, such buildings from the Battle Creek Channel as in the opinion of the District Engineer may jeopardize the effectiveness of that improvement. At the time of authorization of the improvement the Secretary of the Army recommended in the project document that a cash contribution of $93,000, at report price levels, should be made by non-Federal interests. Assurances of local cooperation were furnished by the city of Battle Creek and were formally accepted by the United States as of December 10, 1956. Lands and rights-of-way downstream of the 20th Street Bridge have been furnished. Acquisition of lands upstream to the cut-off canal and for the cut-off canal are in progress. Funds in the amount of $125,000 have been advanced by the city of Battle Creek. Certain buildings which may jeopardize the improvement are being removed as required. Operations and results during fiscal year. New work: A con- tract for construction in the estimated amount of $381,780 was awarded to the Wright Construction Co. of Lansing, Mich., for the portion of the project between the 20th Street Bridge in the city of Battle Creek downstream to a point just below the Fort Custer Waterworks Bridge. The principal features are clearing, excavation, and seeding. Work commenced on April 1, 1957. The clearance of 58 acres and the removal of 22,980 cubic yards, bin measure, of material was accomplished. Planning work was continued. Total costs this fiscal year for new work were $182,099. Condition at end of fiscal year. The project was 6 percent com- plete at the end of the fiscal year. The contract completion date is May 9, 1958. Insufficient work had been completed at the end of the fiscal year to provide any measurable flood protection to the city of Battle Creek.

SEBEWAING, SEBEWAING RIVER, MICH. Location. The Sebewaing River drains an area of about 105 square miles in Huron and Tuscola Counties on the westerly side of the Thumb area of the Lower Peninsula of Michigan and dis- charges into Saginaw Bay, an arm of Lake Huron, about 20 miles northeast of the mouth of Saginaw River. The village of Sebewaing is located near the mouth of the river. (See United States Lake Survey Chart No. 5.) Existing project. This provides for the enlarging of the pres- ent channel of the Sebewaing River through the village of Sebe- waing, Mich., to a capacity of 7,500 cubic feet per second from the junction of the Columbia and State drains to a point 4,500 feet lakeward of the railroad bridge near the mouth, for altering the railroad bridge and three highway bridges to permit free passage of ice; and for removal of the present dike on the south side of the channel lakeward of the railroad bridge. The project is designed to provide protection for the village of Sebewaing from floods with a frequency of occurrence of once in 15 years and with a magnitude greater than the maximum flood of record. The estimated cost of new work, revised in 1951, is $380,500. The average annual maintenance cost during the past 5 years was $2,265. The existing project was authorized by the Flood Control Act approved August 18, 1941 (H. Doc. 286, 76th Cong., 1st sess.). This document contains the latest published maps. Local cooperation. With the exception of the furnishing of easements and rights-of-way for the removal of the remaining portion of the dike on the south side of the channel lakeward of the railroad bridge, all requirements of local cooperation have been complied with. Operations and results during fiscal year. Condition surveys were made at a cost of $236. An adjustment was made in the cost of removing ice jams which was accomplished in fiscal year 1956 and involved an additional cost of $1,051. Total costs for maintenance during this fiscal year were $1,287. 1352 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Condition at end of fiscal year. The work required to construct the project is 95 percent complete. The incomplete portion of the project consists of the removal of the remainder of the old earth dike on the south side of the channel lakeward of. the railroad bridge. All items of the project are in good condition with exception of the channel which has shoaled to considerable extent throughout the entire length, and extensively at the upper end of the project and downstream of the railroad bridge.

(See Lake Series No. 4, revised 1950, Corps. of Engineers.) Operations and results during fiscal year. Miscellaneous in- spection services and condition surveys were accomplished by Government plant and hired labor at a cost of $5,998. The U. S. hopper dredge Hoffman removed 229,261 cubic yards, bin measure, of shoaled material over approximately 1.5 miles of the Black River channel and a 20,000 square yard area of the outer harbor, for restoration of project depths of 24 and 25 feet, at a cost of $67,720. The U. S. derrick boat McCauley repaired 110 linear feet of the west breakwater and 74 linear feet of the east breakwater, at a cost of $28,794. Snagging and clearing in project channels were accomplished by Government plant and hired labor at a cost of $5,593. The total.cost for maintenance was $108,105. 'Conditionat end of fiscal year. The existing project was com- pleted in 1951 at a cost of $2,748,513 (including $3,000 con- tributed by local interests). An outer harbor has been pro- vided by constructing breakwaters and pierheads completed in 1915, except the extension of the west breakwater to shore, which was completed in 1921. A channel through the outer harbor to the entrance to Black River was deepened to 25 feet in 1937, also a channel 16 feet deep to the municipal pier was provided in 1986. Deepening the outer harbor was completed in 1946. The entrance to the river has been improved by the construction of parallel piers completed in 1909. Widening of two bends in the river was completed in 1934. The river channel and upstream turning basin opposite the National Tube Co. dock were deepened to project depth in 1937 and 1938 and the turning basin widened in 1944. Deepening of the downstream turning basin in the bend of Black River immediately upstream of the Baltimore & Ohio Railroad coal dock to project depth of 20 feet was completed in 1951. The protection works are generally in poor condition:. The shoreward section of the west breakwater which was completed in 1921 has disintegrated and settled and in places is below low water datum. At various locations on the lake face of::thelake- ward section of the west breakwater stones have shifted .- eaving holes in the wall, and in many sections of the east breakwater the stones above water have deteriorated and shifted. The concrete superstructure of the East Pier is badlyrdeteriorated. The controlling depth is 25 feet in the channel through the outer harbor, 24 feet in the river channel to the upper end of the National Tube Co. dock, 16 feet in the.- outer harbr;hannel to 1362 REPORT OF THE CHIEF OF ENGINEERS, U.

ARMY, 1957 response to resolution for review of reports on Cleveland Harbor, Ohio and recommends modification to the existing project to provide for: (1) a channel generaly 500 feet wide and 25 feet deep through the east basin of the outer harbor, at an estimated cost to the United States of $535,000 for construction and $4,000 annually for maintenance in addition to that now required; (2) replacement of the Erie Railroad bridge over the Cuyahoga River at mile 4.1 and widening of the channel at that point, with elimi- nation of the reconstruction of the east pier of the bridge as now authorized for the existing project at a cost of $208,000, at an estimated cost to the United States of $7,402,000 for construc- tion in addition to that now .authorized and no increase for annual maintenance; and (3) replacement of the Baltimore and Ohio Railroad bridge over Old River near its mouth and the Willow Avenue Highway Bridge about 800 feet above the mouth, and widening of the channel at four locations along the lower 2,000 feet of the river, at an estimated cost to the United States of $6,990,000 for construction and $300 annually for maintenance in addition to that now required. All estimated costs are on April 1956 price levels. Local cooperation. Assurances required for the improvements authorized by the July 24, 1946, act were received and approved on May 3, 1949, by the Assistant Secretary of the Army. Nego- tiations for furnishing lands, easements, and rights-of-way are currently under way by the city of Cleveland. All other conditions are fully complied with. Total estimated costs for all requirements of local cooperation under terms of the project authorization amount to $10,106,000 (July 1957). Terminal facilities. There are approximately 48 terminals for the handling of various types of cargoes, the most important of which are iron ore, steel products, coal, scrap, cement, sand and gravel, stone, grain, petroleum products, automobiles, newsprint paper, salt, sulfur, coke, coal tar, and fish. In general, the terminals operated by the railroads, which include 2 of the iron- ore and a coal terminal, are open to shippers of the commodities handled. The city of Cleveland owns three terminals, one of which is leased for a miscellaneous freight and automobile termi- nal. The Corps of Engineers owns a wharf at the foot of East Ninth Street which is private. Several yacht club docks and numerous other privately owned servicing and storage docks are for recreational and other small craft. The facilities are con- sidered adequate for the existing commerce. (See Lake Series No. 3, revised 1950, Corps of Engineers.) Operationsand results during fiscal year. New work: Reloca- tions, consisting of replacement of railroad bridges 1, 15, and 3 over the Cuyahoga River, were carried on by separate continuing contracts, and widening of Cuyahoga River was continued. At the end of the fiscal year, bridge No. 1 was 89 percent completed, bridge No. 15 was 87 percent completed, bridge No. 3 was 92 percent completed, widening at bridge No. 9 was completed and widening in the vicinity at bridge No. 1 was 15 percent completed. Maintenance: Miscellaneous inspection services and condition RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 1365 surveys were accomplished by Government plant and hired labor, at a cost of $9,962. The U. S. hopper dredges Lyman and Hoffman removed a total of 471,716 cubic yards, bin measure, of shoaled material over an area of approximately 300,000 square yards of the outer harbor and entrance channel for restoration of project depths of 23 and 25 feet at a cost of $81,164. The U. S. derrick boats McCauley and Tonawanda repaired approximately 600 linear feet of the east breakwater at a total cost of $81,767 (includes $12,925 deferred maintenance funds fiscal year 1957). Snagging and clearing in the project channels were accomplished by Gov- ernment plant and hired labor, at a cost of $5,258. Maintenance of the Cuyahoga and Old Rivers, by contract, was continued and 573,362 cubic yards, scow measure, of shoaled material was re- moved for restoration of project depth of 21 feet, at a cost of $548,129, (includes $42,075 deferred maintenance funds fiscal year 1957.) Advance spring dredging of the upper Cuyahoga River, by contract, was accomplished and 259,280 cubic yards, scow measure, of shoaled material was removed to approximately 26 feet below low water datum at a cost of $301,900. The total cost was $2,949,843 of which $1,921,663 was for new work and $1,028.180 for maintenance. Condition at end of fiscal year. The existing project is about 90 percent complete. The river entrance channel has been im- proved by the construction of parallel piers 325 feet apart, and dredging to a depth of 25 feet at low water datum up to the New York Central Railroad bridge. The piers were completed in 1900 and the dredging in 1935. An outer harbor, about 1,300 acres in extent, has been formed by the construction of an aggregate length of about 30,000 feet of breakwater, including converging arms, completed in 1915. The main entrance has been widened to 700 feet and protected by converging arms extending lakeward from the east and west breakwaters, completed in 1908. The outer harbor was deepened, 1933 to 1935, to 25 feet at low water datum throughout the west basin, in the entrance channel, and over a portion of the east basin adjacent to the entrance channel; over the remaining nortion of the east basin a depth of 23 feet at low water datum has generally been secured. Portions of the channel in Cuyahoga River were widened each year from 1939 to 1942. Removal of 150 feet of easterly end of west breakwater and construction of 400 feet of spur breakwater to protect the gap in the west breakwater shore arm were completed in 1935. A concrete base for a light tower was constructed at the east end of east breakwater in 1917 in lieu of the east-end pierhead. Pro- viding a 1,300-foot extension of the Cuvahoga River channel to the present project limit was authorized by the River and Harbor Act of March 2, 1945, and partially completed with Defense Plant Corporation funds during 1942. Old River to the Sand Products Corp. dock was deenened to 23 feet in 1952. Replacement of New York, Chicago & St. Louis Railroad bridge No. 25 was com- nleted during April 1953. Replacement of the New Ybrk Central Railroad bridge No. 8 was completed during December 1953. Replacement of New York Central Railroad bridge No. 9 was 1366 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 completed during June 1956 and the channel in the vicinity of the structure widened during 1957. The harbor structures require extensive repairs. Completing the remainder of the channel extension, widening portions of the Cuyahoga River, deepening Cuyahoga River to 23 feet, and replacement or pier reconstruction of four railroad bridges over the Cuyahoga River, remain to be done to complete the project. The controlling depth in the main entrance channel, through the west basin and between the piers, was 25 feet, and in the channel through the east basin, 23 feet. Depths elsewhere in the east basin within the project area range from 10 to 28 feet. The controlling depth in the Cuyahoga River was 21 feet; in Old River to Sand Products Corp. dock, 23 feet; in remainder of Old River, 21 feet; and in the turning basin, 18 feet. The total costs of the existing project were $35,563,825, of which $22,589,049, including $616,767 public works funds, was for new work and $12,974,776, including $125,000 public works funds, for maintenance. In addition, $50,000 was expended from contributed funds for maintenance.

ARMY, 1957 Local cooperation. The River and Harbor Act of January 21, 1927, requires local interests to contribute $304,000 toward the cost of extending the breakwater 4,000 feet, and dredge the channel of approach to their terminal at their own expense. The River and Harbor Act approved July 3, 1930, waived the condition requiring local interests to contribute to the cost of the breakwater extension. The condition requiring dredging has not been complied with. The act of July 24, 1946, provides for the 8-foot channel subject to the condition that local interests agree to hold and save the United States free from damages resulting from the improvement. The assurances were furnished by the village of Fairport on August 16, 1955 and were accepted by the District Engineer, Buffalo District, on September 19, 1955. All other conditions have been complied with. Terminal facilities. One coal dock does a general public busi- ness. Two limestone docks, two limestone and sand and gravel docks, four fish docks, a yacht club dock and one dock equipped with a derrick for handling small pleasure craft, are privately owned. There are no publicly owned terminals. The facilities are regarded as adequate for the existing commerce. (See Lake Series No. 2, 1950, Corps of Engineers.) Operations and results during fiscal year. Miscellaneous in- spection services and condition surveys were accomplished by Government plant and hired labor, at a cost of $7,593. The U. S. hopper dredge Lyman and Hoffman removed a total of 292,635 cubic yards, bin measure, of shoaled material over the entire area of the Grand River channel and 125,000 square yards of the outer harbor for restoration of project depths of 21, 24 and 25 feet, at a cost of $92,853. Snagging and clearing in project channels were accomplished by Government plant and hired labor at a cost of $3,693. Contract plans and specifications for repairs to 274 linear feet of the east pier were completed, at a cost of $8,818 (includes $8,066 deferred maintenance funds fiscal year 1957). The total cost for maintenance was $112,956. Condition at end of fiscal year. The existing project was com- pleted in 1956 at a cost of $2,525,000. A length of 400 linear feet of the east pier was repaired with steel sheet piling and sand filled, in 1949. The river entrance has been improved by the construction of an east pier completed in 1904, and the removal of the old west pier and construction of the bulkhead, completed in 1939. The east breakwater was completed in 1931 and the west breakwater in 1935. The river channel was deepened to project depths, and the turning basin was excavated in 1939. The outer harbor was deepened and the river channel was widened at its mouth in 1940. Deepening the 8-foot depth channel in Grand River at the upper end of and adjacent to the west side of the 21-foot project channel, was completed in 1956. The harbor structures require repairs. The concrete cap of two cells of the cellular section of the west breakwater requires replace- ment. At several places along the remainder of the west break- water and along the east breakwater, the slope stone has disinte- grated and settled. The inner 274 feet of the east pier requires RIVERS AND HARBORS--BUFFALO, N. Y., DISTRICT 1369 replacement and is under contract for accomplishment during Sept. 1957 through June 1958. The outer end of the structure requires extensive repairs. The controlling depth is 25 feet in the outer harbor, 24 feet in the river channel for 3,700 feet upstream from the outer end of the east pier, thence 21 feet in the river channel upstream to the project limit, 18 feet in the turning basin, and 8 feet in project area at upper end of Grand River. All depths are referred to low water datum. The total costs of the existing project were $4,563,315, of which $2,525,000, including $187,772 public works funds, was for new work and $2,038,315 for maintenance.

An entrance 28 feet deep between existing breakwaters 600 feet apart; thence a channel of 25-foot depth and 1,100-foot maxi- mum bottom width through the outer harbor to the old inner east breakwater; thence 24 feet deep to the mouth of Ashtabula River; thence a channel 24 feet deep with a bottom width of 160 feet 1370 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 to a point 2,000 feet upstream; thence a channel 18 feet deep (except where ledge rock may be encountered) with a bottom width of 160 feet decreasing to 100 feet and suitably widened at the southerly end, to the upper car-ferry slip; thence a channel 16 feet deep (except where ledge rock may be encountered) with a bottom width of 100 feet suitably widened at bends and in the turning basin, to the southerly end of the turning basin; thence a channel 16 feet deep with a bottom width of 100 feet to a point 1,550 feet upstream of the turning basin; also an approach channel 24 feet deep, with a minimum width of 250 feet from the 24-foot depth section of the outer harbor eastward to the New York Central Railroad Co.'s slip. f. A 700-foot wide access channel leading southeastward from the present entrance channel and terminating in a basin having a width of 1,200 feet and a length of 1,500 feet, all dredged to a depth of 25 feet in earth and 26 feet in rock. g. Maintenance to 21-foot depth of that portion of the outer harbor between the deepened channel and a meridian line through the westerly angle of the east breakwater. The project depth is referred to low water datum for Lake Erie, which is 570.5 feet above mean tide at New York City. Ordinary fluctuations of water level are from 3.5 feet above to 0.5 foot below low water datum, and extreme fluctuations, produced by the winds or other causes, are from 4 feet above to 1 foot below low water datum. The estimated cost of new work is $7,254,000 (1957), exclusive of amounts expended on previous projects. Portions of the project consisting of the removal of 250 feet of the east inner breakwater at an estimated cost of $128,000 (1954) and extension of the Ash- tabula River channel at an estimated cost of $134,000 (1955), are to be restudied and are excluded from the foregoing estimate.

RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 1371 Local cooperation. Fully complied with. Total estimated costs for all requirements for local" cooperation under terms of the project authorization amount to $4,539,000 (July 1955). Terminal facilities. There are three iron. ore and two coal terminals with an aggregate developed dock frontage of 18,500 feet, all open to the public. There are three privately owned fish docks, one privately owned limestone dock, one limestone and sand and gravel dock, one salt dock, one dock for sand, gravel, salt and silicon ore, a large inactive shipyard and drydock, and a car-ferry terminal. A yacht club dock and several other privately owned servicing and storage docks are for recreational and other small craft. The facilities are considered adequate for the existing commerce. (See Lake Series No. 2, 1950, Corps of Engineers.) Operationsand results during fiscal year. New work: Deepen- ing the approach channel and turning basin in the east outer harbor to 25-foot project depth was scheduled to be accomplished in two stages. Stage I, which provides a minimum 150-foot wide channel through the east outer harbor to the new docks, was completed in June 1956 except for cleanup work which was accomplished during July 1956. Funds available from fiscal year 1956 appropriation were insufficient to cover the cost of stage I. However, the contractor elected to complete all the work required for stage I and was subsequently reimbursed from fiscal year 1957 appropriation. Preconstruction planning was com- pleted and construction initiated for stage II which provides for deepening the remainder of the project area in the east outer harbor. The total cost for new work was $1,251,777. Maintenance: Miscellaneous inspection services and condition surveys were accomplished by Government plant and hired labor at a cost of $6,288. The U. S. hopper dredge Lyman removed 33,696 cubic yards, bin measure, of shoaled material over an area of 20,000 square yards of the Ashtabula River channel for restora- tion of project depths of 18 and 24 feet, at a cost of $10,867. The U. S. derrick boat McCauley repaired 90 linear feet of the west breakwater at a cost of $20,216. The total cost was $1,289,148 of which $1,251,777 was for new work and $37,371 for maintenance. Condition at end of fiscal year. The existing project is about 62 percent complete. The west breakwater was completed in 1915 except 580 feet of the inner end which was completed in 1923, and 600 feet of the outer end which was completed in 1935. The east breakwater was completed in 1915; 800 feet of the westerly end was removed and a lakeward extension of 700 feet was com- pleted in 1935. The old inner east breakwater 1,200 feet long was completed in 1909, and the westerly 600 feet was removed in 1913 and 350 feet in 1935. The 18- and 16-foot sections of the river channel and the turning basin were deepened to project depth in 1939. The channel through the outer harbor, the ap- proach channel to the New York Central Railroad Co.'s slip, and the channel in Astabula River to a point 2,000 feet upstream from its mouth, were deepened to project depths in 1940. The 150-foot 1372 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 wide approach channel through the east outer harbor to the new dock was completed in 1956 and deepening of the remainder of the east outer harbor and turning basin was initiated during October 1956. The harbor structures require repairs. Portions of both the east breakwater and the west breakwater, where the slope stone has pulled away, the core stone has washed away, and the deck stones have dropped, require major repairs. The work remaining to be done to complete the project consists of deepening the remaining portion of the access channel and basin in the east outer harbor, and restudy of the other features comprising the deepening of the upper 1,550 feet of the river channel and the conditional removal of the east inner breakwater. The portion of the outer harbor to be maintained to 21 feet has not been deepened to that depth, shale rock being above project depth over a portion of the area. The controlling depth is 25 feet in the 150-foot wide east outer harbor approach channel and the channel through the outer harbor lakeward of the inner breakwater, 24 feet shoreward thereof, 20 feet in the east basin, 24 feet in the approach channel to the New York Central Railroad Co.'s slip, and in the Ashtabula River channel to a point 2,000 feet upstream from its mouth, 18 feet to the upper car-ferry slip, and 16 feet up to and including the turn- ing basin. Controlling depth in completed portion of east outer harbor is 25 feet. No controlling depth is established for remainder of east outer harbor. The total costs of the existing project were $6,123,916 of which $4,474,239, including $536,648 public works funds, was for new work, and $1,649,667 for maintenance.

Miscellaneous in- spection services and condition surveys were accomplished by Government plant and hired labor at a cost of $4,075. The U. S. hopper dredge Lyman removed 54,406 cubic yards, bin measure, of shoaled material over an area of approximately 80,000 square yards of the outer harbor for restoration of project depth of 25-feet, at a cost of $18,938. The U. S. derrick boat Tonawanda repaired 422 linear feet of the west breakwater at a cost of $126,024. The total cost for maintenance was $149,037. Condition at end of fiscal year. The existing project is about 63 percent complete. Under the existing project, a length of 4,445 feet of the new west breakwater was completed in 1916; the old east breakwater, 1,050 feet long, was extended shore- ward 800 feet (completed 1911) and lakeward 900 feet (com- pleted 1923). The 1,670-foot shore arm to the west breakwater was completed in 1934. Extension of the west breakwater 830 feet lakeward, the east breakwater 925 feet lakeward, and removal of the lake arm of the west breakwater were completed in 1935; 642 feet of the old west breakwater was removed in 1916, and the remaining 600 feet in 1925. Two piers have been constructed at the mouth of the Conneaut River. Removal of west pier and 459 feet of east pier were completed in 1934. The east pier is now 1,008 feet long. A channel through the outer harbor was dredged to 25 and 26 feet in 1938. The inner 1,200 feet of the west breakwater was rebuilt to its original elevation during 1941 to 1952. At several places along the remainder of the west breakwater and along the east break- water, the slope stone along the lakeside is disintegrating and pulling away and the deck stone is settling. Other harbor structures are generally in fair condition.

Total esti- mated costs for all requirements of local cooperation under terms of the project authorization amount to $958,000 (July 1957). Terminal facilities. The developed waterfront has a length of about 2 miles. Two groups of terminals have been established along this harbor frontage. The westerly group consists of three piers, one of which is used for sand and stone, one for petroleum products, and one for sand and petroleum products. The easterly group consists of one terminal for iron ore, lime- stone, and coal; one for petroleum; one for coal; one for pulpwood; one for sand, stone, and petroleum; one grain elevator; and one municipal pier used as a passenger terminal. There are two small boat basins in which there are docks for fish, marine repair work, and small pleasure craft. The facilities are considered adequate for the existing commerce. (See Lake Series No. 1, 1951, Corps of Engineers). Operations and results during fiscal year. Miscellaneous in- spection services,.and condition surveys were accomplished by Government plant and hired labor, at a cost of $4,437. The U. S. hopper dredge Lyman removed 81,359 cubic yards, bin measure, of shoaled material over approximately one mile of the inner entrance channel and 27,000 square yards of the easterly approach channel for restoration of project depths of 25 feet, at a cost of $33,257. The total cost for maintenance was $37,694. Condition at end of fiscal year. The existing project is 29 per- cent complete. The breakwater and piers were completed in 1915. A 3,050-foot section of rubblemound protection work on the peninsula was completed in 1921, 5,281 feet of steel sheet piling protection work with stone facing were completed in 1930, and two experimental 300-foot stone groins and about 1,385 feet of stone protection work at beach 2 were completed in 1943. The con- struction of 2,750 feet of stone protection work, just north of the Kelso groin, was completed in 1944. The 18-foot harbor basin was deepened in 1900. Widening and straightening of the entrance channel was completed in 1936. The deepening of the entrance channel and approach channel to the easterly docks to 25 feet, except for small triangular areas along the southeasterly and southwesterly limits of the approach channel, was completed in 1939. The 21-foot harbor basin was deepened in 1940. The harbor structures are generally in poor condition. The con- crete superstructure of the north pier has disintegrated, broken, and dropped in various sections. In the outer 200-foot section of the south breakwater, the slope stone on the channel side has pulled away and dropped. A length of 40 linear feet of the south pier and 1,141 linear feet of the north pier has been reinforced and repaired with steel sheet piling and concrete. Approximately 1,400 linear feet of the steel sheet piling bulkhead with stone fac- ing adjacent to the mainland, Presque Isle protection works, con- structed in 1930, in which the stone facing has settled has been completely covered with sandfill as provided in the shore protec- tion project authorized for Presque Isle Peninsula (see page 1409). 1378 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The work remaining to be done to complete the project consists of dredging an approach channel and turning basin to the westerly docks, deepening and widening the approach channel to the easterly docks, and the conditional extension of the north pier. There is a controlling depth of 25 feet at low water datum in the entrance channel and in the approach channel to the docks at the easterly end of the harbor, 15 feet to docks at the westerly end, and 21 feet to the public docks, foot of State Street. The total costs of the existing project were $4,536,727, of which $768,075 was for new work and $3,768,652 for maintenance. In addition, there was a cost and expenditure of $154,500 from contributed funds for maintenance.

Deepening of the 23-foot project area in the outer harbor was completed in 1956 except for strips 50 feet wide along the harbor line and 180 feet wide between the Merchants Refrigerating Co.'s piers and the south end of the city dike. The harbor structures are generally in good condition except at various points of the south breakwater and old breakwater, where the slope stone on the lakeside has been displaced, portions of the stone banquette on the harbor side of the old breakwater have RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 1385 dropped, and the riprap protection along, the lakeside of the northerly 1,200 feet of the old breakwater has settled. The controlling depth in the completed portion of the northerly part of the outer harbor is 22 feet; in the north entrance channel is 21 feet; in the south entrance channel, and the southerly outer harbor is 25 feet; 22 feet in the Buffalo River Entrance channel and in Buffalo River; and 22 feet in the Buffalo Ship Canal; all at low water datum. The work remaining to be done to complete the project consists of the deepening of the north entrance channel to 25 feet in earth and 26 feet in rock; deepening the remainder of the 23-foot outer harbor area. The total costs of the existing project were $14,032,344 of which $8,444,867, including $655,500 public works funds, was for new work; $5,587,477 for maintenance. In addition $390,000 was expended from contributed funds for maintenance.

BLACK ROCK CHANNEL AND TONAWANDA HARBOR, N. Y. Location. This improvement is essentially that of the upper 131/2 miles of the Niagara River from its head at Lake Erie, Buffalo, N. Y., to and including Tonawanda Harbor, N. Y. It comprises the improvements formerly designated by three titles; viz, Lake Erie entrance to Black Rock Harbor and Erie Basin, N. Y., Black Rock Harbor and Channel, New York, and Tonawanda Harbor and Niagara River, N. Y. (See United States Lake Survey Chart No. 312.) Previous projects. Lake Erie section, none. The original project for Black Rock Harbor and Channel was adopted by the River and Harbor Act of March 2, 1829. The original project for Tonawanda Harbor and Niagara River was adopted by the River and Harbor Act of March 3, 1881. For further details, see items 5 and 7, page 1970 of Annual Report for 1915, and page 1612 of Annual Report for 1938. Existing project. This provides for a channel 21 feet deep from Buffalo Harbor north entrance channel, to opposite Sixth Avenue, North Tonawanda, total length 131/2 miles, as follows; from 1386 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Buffalo north entrance channel to the foot of Maryland Street, Buffalo, a distance of about 4,200 feet, about 1,000 to 500 feet wide, with a short branch channel leading to Erie Basin; thence 350 feet wide, narrowing to 200 feet wide, 500 feet northwest; thence generally 200 feet wide through Black Rock Channel to the ship lock at the foot of Bridge Street, a distance of 3.3 miles, widening at the curve opposite the foot of Porter Avenue and at the angle immediately south of the International Bridge. From the lock the channel is 400 feet wide in the Niagara River to the natural deepwater pool at the upstream end of Rattlesnake Island, a distance of 3.4 miles; thence through natural deepwater to the downstream end of the deepwater pool at the Tonawanda water- works intake crib, a distance of about 4.7 miles, widened to 500 feet opposite the Colorado Iron & Fuel Corp.'s plant, by the re- moval of 200 feet of the westerly end of Rattlesnake Island Shoal; thence 400 feet wide to the foot of Tonawanda Island opposite Second Avenue, North Tonawanda, a distance of 5,000 feet, ending in a turning basin about 1,230 feet long and 1,250 feet wide extending to a point opposite Sixth Avenue. The project also provides for the removal of rock shoals from the Lake Erie entrance to the canal, and in the canal south of Ferry Street Bridge, to a depth of 22 feet; for a channel 6,800 feet long, and generally 400 feet wide in Tonawanda inner harbor-the lower 1,500 feet to be 21 feet deep and the remainder 16 feet deep; for a channel 16 feet deep, 1,400 feet long, and generally 180 feet wide in Tonawanda Creek; for a ship lock at Bridge Street, Buffalo; for the repair and 800-foot extension of Bird Island pier; for the improvement and extension of the guide pier; and for the repair of the towpath wall. The project depth in the canal is referred to low water datum in Lake Erie, elevation 570.5 feet above mean tide at New York City. The project depth in the river is referred to the river surface when Lake Erie is at low water datum. Ordinary fluctuations of water level above the lock are from 3.5 feet above to 0.5-foot below low water datum, and extreme fluctuations produced by winds and other causes, are about 9 feet above to 31/ feet below that plane. River fluctuations gradually decrease to about 70 percent of fluctuations above the lock when they reach North Tonawanda. The estimate of cost for new work is $10,675,000 (1957) exclu- sive of amounts expended on previous project's. The improve- ment of guide pier at the Black Rock lock is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1954, and was estimated to be $931,000. The average annual maintenance cost during the past 5 years was $277,000 including $207,000 for operation and care. Descriptionof Black Rock lock Location: Foot of Bridge St., Buffalo, N. Y.

Local cooperation. Fully complied with except for the deepen- ing of the lower 1,500 feet of the Tonawanda Inner Harbor which is subject to the condition that local interests agree to- a. Furnish free of cost to the United States all necessary land, easements and rights-of-way for the new work and subsequent maintenance. b. Hold and save the United States free from damages which may result from construction and maintenance of further improve- ment. c. Provide and maintain suitable depth between the Federal channel and adjacent terminals. Assurances are required from four adjacent dockside owners. Assurances were received during March and June 1957 from three 1388 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 dockside owners and have been accepted by the District Engineer. Submission of the remaining assurances are anticipated during the later part of calendar year 1957. Total estimated costs for all requirements of local cooperation under terms of the project authorizations amount to $1,488,000 (July 1957). Terminal facilities. There are no freight terminals along the channel above the Black Rock lock. Along the upstream end of the channel there are two small boat harbors, one unused seaplane terminal, one naval militia dock, two yacht club docks, and several other privately owned servicing and storage docks for recreational and other small craft, and two State-owned barge canal terminals at Erie Basin. Below the Black Rock lock and at Tonawanda Harbor, there are eight terminals for petroleum products, two for iron ore, stone, and pig iron, two for coal, one for molasses, four for sand and gravel, one for lumber, and one for pulpwood, all of which are private. There are also two State-owned barge canal terminals at Tonawanda, N. Y. There are seven marine service and supply docks for recreational and other small craft. The Corps of En- gineers owns a wharf adjacent to the Black Rock lock, which is private. The facilities are considered adequate for the existing commerce. (See Lake Series No. 1, revised 1951, Corps of Engineers.) Operations and results during fiscal year. New work: Pre- construction planning for deepening the lower 1,500 feet of the Tonawanda Inner Harbor from 16 to 21 feet deep was initiated by hired labor, and was 80 percent completed. Total cost for new work, $4,714. Maintenance: Miscellaneous inspection services and condition surveys were accomplished by Government plant and hired labor at the project. The U. S. hopper dredge Lyman removed 35,246 cubic yards, bin measure, of shoaled material from the Black Rock Canal and Niagara River for restoration of project depths. The U. S. derrick boat Niagara repaired sections of Bird Island pier and accomplished snagging and clearing in the project channels. Operation and care-Black Rock Lock: The lock was in con- tinuous operation 275 days and closed for the winter season- January 1 through April 1, 1957, inclusive. Ordinary mainte- nance and repair of structures and grounds were accomplished throughout the year. The signal station, located on the canal at the foot of West Genesee Street, was in continuous operation 245 days.

Y., DISTRICT 1389 Condition at end of fiscal year. The existing project is about 87 percent complete. The channel from Buffalo Harbor north en- trance to opposite Sixth Avenue, North Tonawanda, is complete. The different sections of this channel were completed to project depth as follows: Lake Erie section in 1909; Black Rock Canal section in 1915; Niagara River section from lock to deepwater pool above Tonawanda, in 1913; and Tonawanda section, including turning basin, 1921. The channel was further widened as follows: the triangular area at Lake Erie entrance to the canal was com- pleted in 1922 and transferred from Buffalo Harbor project in 1945; Lake Erie section was widened at the bend opposite foot of Georgia Street, Buffalo, in 1924; Black Rock Canal section, just south of the International Bridge at Buffalo, in 1928, and opposite the foot of Maryland Street, Buffalo, in 1930; and Niagara River section in the vicinity of the westerly end of the Rattlesnake Island shoal in 1928. Rock shoals extending above a depth of 21.4 feet were removed from the Lake Erie entrance to the canal and in the canal south of Ferry Street Bridge, in 1937. Rock shoals extending above a depth of 22 feet were removed from the Lake Erie entrance to the canal, in Black Rock Canal, and in the Niagara River portion of the canal in 1948-1949. The Tonawanda Creek Channel was completed in 1902. Tona- wanda Inner Harbor Channel was completed in 1904. The en- largement of the Tonawanda turning basin and the extension of Bird Island pier, were completed in 1936. The lock, including wing walls and retaining walls above the lock, was completed in 1914, and the 100-foot east wing wall extension in 1927. The guide pier connecting with the west lower wing wall was completed in 1916, except for the 200-foot northerly extension and construc- tion of concrete platform in the angle. The upstream 100 linear feet of the lower West Guide pier were repaired during 1951. The bridge at Ferry Street, operated and maintained by the city of Buffalo since 1954, was completed in 1914, and the lock-operating houses in 1924. The work remaining to be done to complete the project consists of improvement and extension of the guide pier, as authorized by the River and Harbor Act of August 30, 1935, widening the Lake Erie entrance to the canal, and deepening of the lower 1,500 feet of the Tonawanda Inner Harbor. All structures are in poor condition. Both the towpath wall and Bird Island pier are badly deteriorated and require considerable annual maintenance. Several sections of the towpath wall fail yearly, requiring removal of stone and debris from the channel and repair of the structure. The operating equipment and con- trols for the Black Rock lock are antiquated and inefficient. The east channel face of the lock wall was repaired in 1953, and the west channel face in 1954. The upper wing wall of the lock has shifted laterally approximately 2 feet at the maximum point, and the concrete superstructure on the lower wing wall is badly cracked, indicating a possible failure of the timber-crib. 1390 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The controlling depths at low water datum are Black Rock Chan- nel 21 feet, 20 feet in the Niagara River section of the channel and in the Tonawanda turning basin, Tonawanda Inner Harbor 14 feet, and Tonawanda Creek Channel 12 feet. The costs of the existing project were $15,728,505, of which $10,065,812, including $1,764,922 emergency relief funds, was for new work; $2,010,809 for maintenance; and $3,651,884 for operat- ing and care. In addition, the sum of $1,356,007 was expended between July 9, 1914, and June 30, 1935, on the operation and care of the works of improvement under the provisions of the permanent indefinite appropriation for such purposes.

NIAGARA RIVER, N. Y. Location. This improvement covers that portion of the Niagara River from Tonawanda Harbor, N. Y., to Niagara Falls, N. Y., a distance of 71/ miles, and compensating works near the head of the river. The downstream limit of the improvement is about 16 miles from the mouth of the river at Lake Ontario. (See United States Lake Survey Chart No. 312.) Previous projects. Adopted by River and Harbor Acts of July 13, 1892, August 18, 1894, and June 25, 1910. For further details, see page 1970 of Annual Report for 1915, and page 1619 of Annual Report for 1938. Existing project. This provides for a channel 12 feet deep and 300 feet wide in the east channel from the downstream end of the existing 21-foot channel opposite Sixth Avenue, North Tonawanda, to the upstream end of the 12.7-foot channel near the Niagara Falls waterworks intake crib; and for a channel 12.7 feet deep and from 1392 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 300 to 400 feet wide from the Navy Island channel (natural) to the foot of Hyde Park Boulevard (formerly called Sugar Street), Niagara Falls, N. Y. The project also provides for the construction of compensating works just above the contracted section of the river at Fort Erie, this work forming a part of the project for deeper channels in the connecting waters of the Great Lakes. The project depths are referred to the river surface when Lake Erie is at low water datum, elevation 570.5 feet above mean tide at New York City. Ordinary fluctuations of water level are from 3 feet above to low water datum, and extreme fluctuations, produced by wind and other causes are from 51/2 feet above to 11/ feet below that plane. The estimate of cost for new work is $463,000 (1954) exclusive of $27,563 contributed by local interests and amounts expended on previous projects. The construction of the compensating works portion of the project is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1954, and was estimated to be $2,887,000. The average annual maintenance cost during the past 5 years was $6,000.

NIAGARA REMEDIAL WORKS, N. Y. Location. The improvement is located in the Niagara River adjacent to the cities of Niagara Falls, N. Y., and Niagara Falls, Ontario, Canada. (See U. S. Lake Survey Charts Nos. 312 and 31.) Previous project. Authorized by Senate executive resolution dated November 27, 1941, ratifying Executive G, 77th Congress. For further details, see pages 2189 and 2190 of the Annual Report for 1949. Existing project. The plan of improvement provides for the following: (1) Chippawa-Grass Island Pool control structure ex- tending 1,550 feet from the Canadian shore out into the Niagara River parallel to the existing submerged weir and about 300 feet downstream therefrom. With the exception of an approach fill adjacent to the Canadian shore, the structure will consist entirely of piers and 13 movable control gates; (2) excavation in the Horse- shoe Cascades lying immediately upstream from the Canadian flank of the Horseshoe Falls and a crest fill on that flank about 100 feet long; (3) excavation in the Horseshoe Cascades lying im- mediately upstream from the Goat Island flank of the Horseshoe Falls and a crest fill on that flank about 300 feet long. Construc- tion of the Chippawa-Grass Island Pool control structure and ex- cavation in the Horseshoe Cascades on the Canadian flank will be accomplished by the Government of Canada. Excavation in the Horseshoe Cascades on the Goat Island flank will be accomplished by the Government of the United States. The estimate of cost for new work is $12,440,000 (1957) ex- clusive of amounts expended on previous projects. In accordance with article II of 1950 treaty, costs will be divided equally between the Governments of United States and Canada. The existing project was authorized by a treaty concerning the uses of the waters of the Niagara River between the United States and Canada as signed at Washington, D. C., on February 27, 1950, approved by the Canadian Parliament on June 14, 1950, consented 1394 REPORT OF THE CHIEF OF ENGINEERS, U. SA- ~MY; 1957 to by the U. S.

Y., DISTRICT 1401 and subsequent maintenance, as and when required; hold and save the United States free from damage due to the construction and subsequent maintenance of the project; construct a wharf about 1,300 feet long, including the necessary extension of the water in- take line, in accordance with plans approved by the Chief of Engi- neers, and construct handling and storage facilities of such design and capacity as to insure expeditious handling and adequate stor- age for the wood pulp required by paper mills in the vicinity, and for prospective commerce in soybeans; dredge and maintain the area between the project limit and wharf face to project depth; and agree to receive, handle and store, at reasonable and equal terms to all, the wood pulp requirements of paper mills in the vicinity. Assurances of local cooperation were furnished and submitted for approval. The assurances were returned without action because they were not in strict accordance with the require- ments. Negotiations are in progress to obtain the revised assur- ances. All prior conditions have been complied with. Total estimated costs for all requirements of local cooperation under terms of the project authorizations amount to $2,668,000 (July 1957). Terminal facilities. One coal terminal and two State-owned terminals for grain and barge canal traffic are open to the public. Two terminals for coal, one for cement, one for woodpulp, and one for fish are private. One dock owned by the State naval militia and one by the city of Oswego are used by recreational craft. The facilities are considered adequate for the existing commerce. Operations and results during fiscal year. New work: Pre- construction planning for removal of shoals in the approach to the harbor entrance was completed and preconstruction planning for the detached breakwater was continued, all at a cost of $38,600 for the year. Removal of shoals in the approach to the harbor en- trance was initiated during May 1957 by Government plant and hired labor and was 85 percent completed at a cost for the year of $146,835. Maintenance: Miscellaneous inspection services and condition surveys were accomplished by Government plant and hired labor at a cost of $4,026. The U. S. hopper dredge Lyman removed 60,156 cubic yards, bin measure, of shoaled material over an area of 75,000 square yards of the outer harbor for the restoration of project depths of 21 and 22 feet at a cost of $16,667. The U. S. derrick boat Niagara repaired 120 linear feet of the west break- water at a cost of $27,097. Snagging and clearing were accom- plished by Government plant and hired labor at a cost of $2,266. The total cost was $235,491, of which $185,435 was for new work and $50,056 for maintenance. Condition at end of fiscal year. The existing project is about 21 percent complete. The west outer breakwater was completed in 1882, and was originally 6,032 feet long with a 119-foot gap near the westerly end, but was reduced to 4,359 feet in 1931, and the gap was closed in 1942. The west arrowhead breakwater was completed in 1931, and the east arrowhead breakwater in 1932. The old lighthouse pier, a part of the west inner breakwater, and 1402 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 the upper and lower islands in Oswego River, were removed in 1931. A depth of 21 feet was obtained in Oswego River to within 50 feet of the harbor line and in the outer harbor east of the Lackawanna coal dock, except a strip about 200 feet wide along the harbor line east of the mouth of the river, in 1932. The chan- nel in Oswego River was widened to the harbor lines in 1937. A channel, 16 feet deep and 100 feet wide, with a turning basin at its westerly end, was dredged in 1932 in the outer harbor west of the Lackawanna coal dock. The channel was widened to 250 feet and deepened to 21 feet below low water datum in 1948. The removal of shoals to 25 feet in the approach to the entrance channel was initiated and partially completed. The breakwaters are generally in fair condition except that the riprap protection along the lake side of the old west breakwater for a length of approximately 1,000 feet has settled, and a 400-foot portion of the concrete section has disintegrated and broken; slope stone in portions of the west arrowhead breakwater has disintegrated and settled and the core stone in a 1,500-foot section of the west breakwater has settled in many places. A depth of 21 feet at low water datum is available in the Oswego River to the north line of Seneca Street, and in the outer harbor east of the Lackawanna coal dock, except in a 200-foot wide strip along the harbor line east of the mouth of the Oswego River which has a controlling depth of 18 feet. The 250-foot channel in the outer harbor west of the Lackawanna coal dock and the turning basin have a controlling depth of 21 feet at low water datum. The work remaining to be done to complete the project is the deepening of the 200-foot strip along the harbor line east of the Oswego River, deepening the remainder of the outer harbor west of the Lackawanna coal dock, construction of the east outer harbor, construction of the detached breakwater, and completion of removal of shoals in the approach to the harbor entrance.

(See United States Lake Survey Chart No. 13.) Previous projects. Adopted by River and Harbor Acts of March 2, 1867, August 2, 1882, and September 19, 1890, by authority of the Chief of Engineers dated February 27, 1897; and by River and Harbor Act of March 3, 1899. For further details of previous projects, see page 1975 of Annual Report for 1915, and page 1635 of Annual Report for 1938. Existing project. This provides for an upper entrance channel 400 feet wide, a city waterfront channel 350 feet wide, and for a lower entrance channel 250 feet wide, all suitably widened at entrances to, and at angles in channels and all 19 feet deep; and for a lower basin 2,400 to 3,500 feet wide and 21 feet deep, extending from deep water in the river to within 50 feet of the existing dock lines. The project depths are referred to the river surface when Lake Ontario is a low water datum, elevation 244 feet above mean tide at New York City. Ordinary seasonal fluctuations of water surface are from 4 feet above to 0.5 foot below low water datum. Other fluctuations due to wind and other causes are small. The estimate of cost for new work is $375,000 (1954), exclusive of amounts expended on previous projects. The removal of re- maining hard-material shoals from the lower basin portion of the project is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was last revised in 1954, and was estimated to be $183,000. The average annual maintenance cost during the past five years was $4,000.

Operations and results during fiscal year. New work. The State of New York has requested the Corps of Engineers to design the outlet structure at Grindstone Creek and has advanced an amount of $5,000 to finance the costs of the requested planning work. Planning by hired labor was initiated and the total cost for the year was $977, all of which was expended from the contributed funds. Condition at end of fiscal year. The State of New York be- tween the period from October 1953 to July 1954 has constructed, under two separate contracts, a new groin, a short section of stone revetment, and the placement of a portion of the authorized beach fill. Plans and specifications for this work were subsequently approved by the Chief of Engineers on February 16, 1956 as forming a part of the authorized project. No other construction has been done and the existing project is about 14 percent completed. No Federal funds have been expended to date. The State of New York has previously expended $55,923 for construction of portions of the project.

LAWRENCE SEAWAY DEVELOPMENT CORPORATION Constitution and duties. The St. Lawrence Seaway Develop- ment Corporation was created by Public Law 358, 83d Congress, 2d session, approved on May 13, 1954. The Corporation was authorized to construct, in United States territory, deepwater navigation works substantially in accordance with the "Controlled single stage project, 238-242" (with a controlling depth of 27 feet in channels and canals and locks at least 800 feet long, 80 feet wide, and 30 feet over the sills), designated as "works solely for navigation" in the joint report dated January 3, 1941, of the Canadian Temporary Great Lakes-St. Lawrence Basin Committee and the United States St. Lawrence Advisory Committee, in the International Rapids section of the St. Lawrence River together with necessary dredging in the Thousand Islands section; and to operate and maintain such works in coordination with the St. Lawrence Seaway Authority of Canada. Responsibility of the Corps of Engineers. The St. Lawrence Seaway Development Corporation by letter to the Secretary of the Army, dated September 17, 1954, designated the Corps of Engi- neers to represent the Corporation as agent for design and construction of the project. Location. The St. Lawrence River is part of a system which comprises all of the five Great Lakes with their drainage area and connecting waterways, and the St. Lawrence River proper from Lake Ontario to the Gulf of St. Lawrence, with its tributaries., 1414 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Project. The project involves the construction of navigation facilities in the reach of the St. Lawrence River that is between the United States and Canada, and coordination thereof with the power facilities to be constructed concurrently by others. The project has been divided into four sections, namely; Thousand Islands, Point Rockway, Long Sault Canal, and Cornwall Island. In the Thousand Islands section only channel dredging is required; in the Point Rockway Section a channel and lock structure is to be constructed; in the Long Sault Canal section a channel, two lock structures, highway tunnel, access roads, maintenance and operation facilities, and miscellaneous appurtenant works; and, in the Cornwall Island section channel dredging, training dikes, removal of the existing high-level bridge and construction of a new International high-level bridge with necessary relocated access roads thereto. In addition, General Purpose Facilities are required consisting of navigation aids anid related facilities and an operational building for the Saint Lawrence Seaway Development Corporation at Massena, N. Y. Operations and results during fiscal year. Preparation of de- tailed plans and specifications for the Thousand Islands Section was completed and was continued for the Long Sault, Cornwall Island and General Purpose Facilities. Portions of the precon- struction planning are completed, contracts have been awarded and construction of practically all major project features are now underway. a. Thousand Islands Section. The channel dredging comprises the removal of shoals from the St. Lawrence River and the work has been divided into two stages with geographical limits for the initial stages commencing in the vicinity of Clayton, N. Y. to approximately 1 mile downstream of Alexandria Bay, a distance of 12 miles and with geographical limits for the second stage commencing at the downstream limit of the initial stage and proceeding further downstream to a point about 8 miles upstream of Morristown, N. Y. where the channel crosses the International Boundary into Canadian waters. Contract operations for the initial stage were initiated on August 16, 1956 and were 30 percent complete at the end of the fiscal year. A contract was awarded for the second stage on June 28, 1957 and dredging operations will be initiated in July 1957. b. Long Sault Section. Excavation for the upstream section, and for the main land portion, of Long Sault Canal were con- tinued by contracts. Construction of Dwight D. Eisenhower and Grass River locks were continued by contracts. At the end of the fiscal year contract operations for the general construction of the Dwight D. Eisenhower lock were about 58 percent complete and for Grass River lock were about 56 percent complete. Operations were continued on numerous lock machinery and electrical supply contracts some of which were completed during the year and the completed units were delivered to the concerned lock sites. A con- tract was awarded for providing a channel in the downstream approach to the Grass River lock and dredging operations were initiated during June 1957. Contract for construction of a gate MISCELLANEOUS ACTIVITIES-BUFFALO, N. Y., DISTRICT 1415 lifter was awarded and fabrication of hull material was initiated during May 1957. A contract for furnishing a spare miter gate was awarded and work on the gate commenced during June 1957. c. Cornwall Island Section. For construction of the Inter- national High Level Bridge the substructure is to be accomplished by Canada while the superstructure is the responsibility of United States. Construction of the substructure (by Canada) was initiated by contract during December 1956. A contract for construction of the superstructure (by United States) was awarded during November 1956 and site clearing operations were initiated during May 1957. Dredging of the south channel was geographically divided into five sections, designated as sections A to E progressing from about one mile upstream of the location of the International High Level Bridge crossing to about one mile downstream of the bridge. Dredging operations for sections C and D were initiated by separate contracts during May 1957. Dredging operations for section A were initiated by government owned plant and hired labor during June 1957. Construction of training dike "B" was initiated by contract during May 1957. d. General Purpose Facilities. Construction of navigation aids and related facilities was subdivided into areas by geographical limits to be accomplished by several contracts. Contract for the initial stage has been awarded and work will be initiated during first quarter fiscal year 1958. No other contracts have yet been awarded. Construction of an operational building at Massena, N. Y. for the Saint Lawrence Seaway Development Corporation was initiated by contract during November 1956 and was about 15 percent complete at the end of the fiscal year. Total cost of the contracting authority delegated to the Corps of Engineers for the year was $45,643,252. In addition, $973,107 non-Federal construction costs were incurred. Condition at the end of the fiscal year. For the contracting authority delegated to the Corps of Engineers operations are about 55 percent complete. Virtually all major project features are under contract and either in progress or in preparatory stage of construction. Preparation of detailed plans and specifications for minor appurtenant project features has progressed satisfac- torily and work is being continued. The work remaining to be done consists of completion of construction underway by numerous contracts; completion of numerous machinery and electrical supply contracts; dredging sections B and E of South Cornwall channel; construction of operational buildings at lock sites; construction of marine base for floating plant; construction of the spare gate storage pit; and construction of remaining navigation aids and related facilities. No work is scheduled for Point Rockway. The total cost of the contracting authority delegated to the Corps of Engineers was $57,583,239. In addition $1,317,050 non-Federal construction costs have been incurred; UNITED STATES LAKE SURVEY This district embraces the United States portion of the Great Lakes-St. Lawrence River drainage basin, Lake Champlain, the lakes and other naturally navigable waters of the New York canal system, and the Minnesota-Ontario border lakes. In addition, contiguous Canadian areas are included where essential to the integrity of charting and other activities. IMPROVEMENTS Navigation 1. Survey of Northern and Northwestern Lakes-------------------1417 General Investigations 2. Examinations and surveys- -____----------1425 1. SURVEY OF NORTHERN AND NORTHWESTERN LAKES Location. The region thus covered, in which operations are conducted for the benefit of navigation and other interests, lies within the States of Vermont, New York, Pennsylvania, Ohio, Michigan, Indiana, Illinois, Wisconsin, and Minnesota. The Great Lakes portion alone covers 61,000 square miles of United States waters and 4,000 miles of United States coast line. The Lake Champlain portion covers 430 square miles and 560 miles of coast line of that lake. The additional New York State portion stretches 62 miles along the canalized waters of the State from the south end of Lake Champlain along the Hudson River to the head of tidewater at Albany and 333 miles westward from Troy at the confluence of the Hudson and Mohawk Rivers along the Erie Canal to Lyons, along the Oswego Canal to Oswego, and along the Cayuga and Seneca Canal into the Finger Lakes. The Minnesota-Ontario border lakes portion reaches about 300 miles from Lake Superior to and including Lake of the Woods in the Hudson Bay drainage basin. Previous projects. In the region described, previous projects of the Lake Survey have specified provision of complete navigation charts designed to suit the needs of existing use of the waters. These projects, in addition to hydrographic and topographic str-. veys, contemplated the establishment of the requisite horizontal and vertical control where not already in existence, and the measurement and analysis of other factors pertaining to naviga- tion. The most recent comprehensive statement concerning prior projects on the Great Lakes, and formulation of "a general project covering to completion the operations of the Survey" appeared in the Annual Report for 1907, pages 844 to 850. The Sundry Civil Act of March 4, 1911, extended the charting responsibility to include the lakes and other naturally navigable waters of the New York canals. The project extension contem- plated compilation of navigation charts of the added waters from all existing survey data pertaining thereto, supplemented by such additional surveys as might be required. The scope of responsibility was again extended by the Sun ry Civil Act of June 23, 1913, to include Lake Champlainand again 1417 1418 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 by the Sundry Civil Act of August 1, 1914, to include the Minne- sota-Ontario boundary waters from Lake Superior to Lake of the Woods. Here, as in the extension to the New York canals, the project extensions contemplated compilation of charts from existing surveys, supplemented by additional surveys as required. Responsibilities of the United States Lake Survey in the Great Lakes portion of the region covered, apart from the charting and navigational aspects, consist of those pertaining to lake levels, hydrology, and hydraulics of the connecting and outflow rivers. The 1907 Annual Report, referred to above in connection with the charting and navigational portions of the project, also discussed prior and existing responsibilities in these respects. A board appointed by the Division Engineer, Great Lakes Division, to study and clarify United States Lake Survey activities in this second category formulated a report which included definite recommendations. The board report was presented to the Chief of Engineers and approved on January 21, 1935, as the basic description of such responsibilities. Thus the report is the foun- dation for the continuing activities of the United States Lake Survey relating to lake levels, hydrology, and hydraulics. It is to be noted that these activities do not include the waters separate from the Great Lakes, which were added for charting only. Existing project. That portion of the existing project con- cerned with charting provides for general maintenance of chart coverage. Various classes of charts are issued, consisting essen- tially of general charts employing small scales, suitable for the needs of open-lake navigation; coastal, river, and sectional charts employing medium scales affording greater detail for closer navigation in the areas covered; harbor and confined locality charts employing large scales showing details pertinent to the restricted navigation involved; and special charts such as those of the Minnesota-Ontario border lakes employing scales suitable to the purposes intended. The number of charts and individual chart scales and coverages are not fixed. Changing requirements of navigation render existing charts inadequate, alter coverage and scale requirements, and make new charts desirable. Within the region assigned for charting, the project is flexible in permitting alterations to keep abreast of changing needs. Closely related to charting, but pertinent to lake levels and hydraulics as well, is the portion of the project relating to hori- zontal and vertical control. The original control was established under the early projects in connection with the initial surveys by the United States Lake Survey on the Great Lakes and by other Government agencies in the other areas of the district. The original control has been preserved wherever possible; where destroyed, it has been replaced as needed, and where necessary, it has been augmented by additional control for use in connection with later surveys and other Corps of Engineers work. Present efforts are directed toward preservation of both horizontal and vertical control by periodic recovery of monuments, replacement when they are found destroyed or damaged, determination of U. S. LAKE SURVEY 1419 correctness of elevations by instrumental means and water trans- fers, and augmentation where required for United States Lake Survey and North Central Division activities. In the same connection, necessary readjustments are made as indicated to correlate United States Lake Survey horizontal control with nationwide horizontal control networks of the United States Coast and Geodetic Survey. The project includes publications of information for the benefit of navigation, in addition to that provided by the charts. These consist primarily of the Great Lakes Pilot and the supplements thereto. The Pilot, issued annually, supplies full descriptions of physical conditions of the waters charted and the particulars of constantly changing conditions not adapted to adequate or prompt representation on the charts. The supplements, issued monthly during the navigation season, provide corrections and additions to the Pilot text occasioned by constantly changing conditions in the navigational areas. Revisory material for the annual editions of the Pilot and material for the supplements are collected by United States Lake Survey sections operating in the field, the various Corps of Engineers districts having jurisdiction over the waters concerned, and by other United States and Canadian governmental organizations. Other data collected and disseminated to navigation, or included in the project for future collection and dissemination, consist of such features as lake and river bottom characteristics, water temperatures, etc. This phase of activity often requires field determination, analysis of data, and publication of results. Since 1859, lake level gages installed and operated by the United States Lake Survey have provided a continuous record of stages of the Great Lakes and their connecting rivers. These records have interest in both the navigational and hydraulic aspects of the work. The present project provides for continued operation of sufficient gages for these purposes and includes reduction of the records obtained, tabulation and study of the data, use in other studies such as that of movement of the earth's crust, and publication of the results in various forms. In the field of hydraulics, the present project provides for con- tinuing studies of all phases relating to the connecting and outflow rivers to affirm the fundamental laws of flow or to determine the changed relationships resulting from changes in river regimen. In addition to the operation of stage recorders, as discussed above, periodic and special measurements of current velocities and river discharges are involved. The fundamental flow relationships determined and the equations derived enter into such studies as lake level regulation, compensations for increases in river capacity caused by channel improvements, diversions for sanitary purposes and power, changes in river capacity resulting from marine construction, wrecks, commercial sand and gravel dredging, and problems of like nature. The hydrology of the lakes included in the present project, in addition to factors discussed above, deals with precipitation over the lake basins, runoff, evaporation from the lake surfaces, ice 1420 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 retardations and effects, and similar phenomena. The work involves compilation of data, supplied primarily by other organizations, in form to be used in studies and problems discussed above. The over-all responsibility of the United States Lake Survey, involving the measurement of lake and river levels, hydraulics, and hydrology, presented as part of the present project in the foregoing paragraphs, is concerned with the preservation of levels of the Great Lakes, and with the establishment and maintenance of datum planes which are used for control of Corps of Engineers river and harbor work and as planes of reference for navigation charts. Operations and results during fiscal year. Offshore sounding of the western half of Lake Superior, which was started during fiscal year 1956, was completed during July, August, and Sep- tember, using Shoran for positioning the survey vessel. In mid- May, the Surveyship Williams proceeded to Marquette, Michigan, to commence offshore soundings of the eastern half of Lake Superior. Because of the extensiveness of the area to be sounded and the limited range of Shoran, Electronic Position Indicator equipment was used for positioning the vessel. Inshore soundings were conducted on the southwest shore of Lake Huron during the first two months of fiscal year 1957. During the last month, preliminary field work was accomplished in preparation for continuation of the survey northward to Saginaw Bay. The essential function of collecting all data necessary for the triennial revision of the Great Lakes navigation charts was accomplished through full-scale operation of the revisory survey program. Revisory surveys are composed of field survey,work and office reduction of data to a form suitable for the compilation of revised chart editions. Revisory field work includes hydro- graphic surveys over all harbor areas outside the limits of Federal dredging projects, comprising such areas as harbor approaches, mooring slips, and other areas subject to change. It also includes investigating areas where chart inaccuracies are alleged to exist, recording new or changed landmarks, revising names of principal docks, shipping companies, and other waterfront establishments, locating new marine construction, and checking of the fringe-of roads and other topographic features adjacent to the shore line. During fiscal year 1957, revisory surveys were accomplished in harbors on the north and east shores of Lake Michigan, on the north and west shores of Lake Huron, and in the west end of Lake Superior. Routine maintenance of the vertical control network was accom- plished coincident with the triennial revisory survey program. This phase of field activities consists of recovery and replacement of benchmarks where necessary and instrumental levels between selected marks to check their stability. During the year, compu- tations were made to place 232 second and third order triangulation stations on North American Datum of 1927, U. S. LAKE SURVEY 1421 There follows a detailed description of aggregate accomplish- ments in the field during the fiscal year, consolidated according to geographical position on the various bodies of water: Lake Superior: Approximately 5,528 lineal miles of offshore soundings were accomplished between the Keweenaw Peninsula and Duluth, Minn. Sweeping operations were conducted in vicinity of the Apostle Islands over four shoal areas where substantial reductions in depths were obtained. Approximately 2,736 lineal miles of offs'hore soundings were accomplished in the eastern half of Lake Superior. 19 special water level gages were installed in selected United States harbors on Lake Superior for verifying vertical control datum and furnishing. data for crustal movement study. Recovery was made of triangu- lation stations required for the offshore sounding program and all descriptions were revised to incorporate changes in references. Revisory surveys were made of Duluth-Superior harbor. St. Marys River: Gages were examined and vertical control maintenance was accomplished at selected sites along the United States side of the river. Lake Michigan: Revisory surveys were completed and vertical control maintenance was accomplished in all harbors on the west, north, and east shores of Lake Michigan from Two Rivers, Wis., to South Haven, Mich. Lake Huron: Recovery of triangulation stations required for inshore sounding operations was completed and approximately 629 lineal miles of inshore soundings were accomplished between Port Huron and a point 8 miles north of Port Sanilac, Mich. Three special water level gages were installed in Lake Huron for verifying vertical control datum and furnishing data for crustal movement study. Revisory surveys and maintenance of vertical control were accomplished at selected harbors on the west and north shores. St. Clair River: Gaes were examined and vertical control maintenance was.accomplished at selected sites along the United States side of the river. Lake St. Clair: Reconnaissance surveys for chart revision were made and vertical control maintenance was accomplished along the Michigan shore line of the lake. Detroit River: Vertical control maintenance was accomplished at selected sites along the Michigan shore line. Revisory surveys were made along the entire river. Niagara River: The construction of a new water level record- ing gage installation at the Maid of the Mist pool was completed and the gage was put into operation. Discharge measurements on the lower Niagara River for calibrating the new recording gage were started. St. Lawrence River: Discharge measurements were made at Massena Point. In cooperation with Canadian personnel, an in- spection was made of the construction automatic gages for the St. Lawrence seaway and power projects. 1422 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 In addition to the operations listed above, hydraulic and hydro- logic activities included routine inspection and checking of water level gages over the Great Lakes and the connecting and outflow rivers; reduction, tabulation, and dissemination of data relating to lake and river levels: river flows, diversions, precipitation, and other hydraulic and hydrologic factors; and study and prepara- tion of numerous reports on hydraulic and hydrologic problems in connection with such matters as the St. Lawrence Seaway, the deepening of the connecting channels, the'redevelopment of power on the Niagara River, the joint United States-Canada study of basic Great Lakes hydraulic and hydrologic data, and the survey report on water levels of the Great Lakes. Forty-four gaging sites were maintained, of which 40 were equipped with self-registering instruments. Forecasts of the ranges in which the 1956-57 winter low levels and the 1957 summer high levels of the Great Lakes could be expected to occur were made approximately 4 months in advance of the estimated months of occurrence. Peak levels of all lakes during the summer of 1956 occurred within the ranges predicted. Minimum levels of Lakes Superior and Ontario during the winter of 1956-57 also occurred within the ranges predicted. The minimum levels of Lakes Michigan- Huron and Erie during the winter of 1956-57 occurred below the ranges predicted because of below average precipitation on the basins of those lakes. Lakes Erie and Ontario were at or near their summer high levels in June 1957, and both were within the predicted ranges. As of June 30, 1957, Lakes Superior and Michigan-Huron were still rising, but indications were that their maximum levels would be established within the predicted ranges. Data collected by United States Lake Survey field sections, supplemented by information from numerous sources, were com- piled for production of 47 revised chart editions, the revised edition of the New York Canals booklet, two new chart inserts, and 11 chart reprints. Modification in aids-to-navigation and other critical chart data was made by hand on 119,267 copies of the stock of printed charts to maintain it currently accurate to the date of issue or sale. This undertaking involved 1,000,452 separate operations consisting of deletion of changed chart features and addition of the new features. Revised editions of 47 charts, the New York Canals booklet, and 11 reprints were processed and printed during the year. In addition to the charts, 770 hydrographs of lake levels and 15,000 chart catalogs were printed. Chart sales for the year amounted to 87,430 copies which were 9,700 more than the 77,730 copies sold during the fiscal year 1956. The proceeds of sales amounted to $64,736.50. An additional 8,302 charts were issued for official use. The 1957 edition of the Great Lakes Pilot was prepared, the copy was forwarded to the Government Printing Office for reproduction, and the publication became available in March 1957. Supplements Nos. 3 through 7, inclusive, to the 1956 Pilot were prepared and the copy provided to the printing contractor monthly from July through November U. S. LAKE SURVEY 1423 1956. Supplements Nos. 1 and 2 to the 1957 Pilot were prepared in a similar manner in May and June 1957. The United States Lake Survey, as agent for the Superintendent of Documents, sold 2,438 copies of the Great Lakes Pilot during the fiscal year, and transmitted a total of $5,485.50 to that official for such sales. An additional 429 copies of the publication were issued for official use. Sales of supplements to the 1957 Pilot amounted to 2,425 sets, realizing $1,827.75 in sales proceeds. The 429 Pilots which were issued were complemented by 429 sets of Supplements. A total of $900.20 was realized from the sale of 1,240 Waterborne Commerce Statistics publications, parts 1-5. An additional 761 copies of these publications were issued for official use. In addition to the above publications, mimeographed notices of the monthly mean stages of the Great Lakes and tabulations of other hydraulic and hydrologic factors were sent to individuals, newspapers, vessel interests, industrial interests, and Government agencies in both the United States and Canada to which the information is of concern. The foregoing operations were all maintenance. The total cost during the year was $606,316. Reimbursable printing work amounted to $79,952.87, of which $17,167.77 were received for reproducing project and other special maps for Corps of Engi- neers districts and the remainder was received for Army Map Service ground maps. To include the costs of revisory surveys and adjacent inshore soundings in the operations and maintenance budget for each project, direct allotments are not made to the United States Lake Survey for those purposes, but reimburse- ments for the work are made by the districts concerned. Reim- bursable work under this category amounted to $42,800 for in- shore soundings and $77,200 for revisory surveys during the fiscal year 1957. Other reimbursable work accomplished by the Lake Survey for other district offices amounted to $17,885.05 during the fiscal year. Condition at end o f fiscal year. All new work under the various projects has been completed. Work under the existing project is composed solely of maintenance. The total cost of new work under all projects since the inauguration of the survey in 1841, amounted to $6,729,811. New work under the existing project cost $2,755,914 and maintenance thereunder to June 30, 1957, cost $8,084,829, amounting to a total for the present project during its 51 years of existence of $10,840,743. At the end of the fiscal year, publications available for issue to official users and for sale to the general public consisted of 114 charts of the Great Lakes and connecting rivers, five charts of Lake Champlain, three charts (and a volume of 60 small charts) of New York canals, 17 charts of the Minnesota-Ontario border lakes, the 1957 Great Lakes Pilot and the supplements to the Pilot. In addition, mimeographed reports of lake levels showing current elevations, comparisons with past levels, and forecasts of future levels are mailed early each month to a list of about 1,700 official and private recipients; and tabulations of river discharges, pre cipitation, and stages at specific locations on the lakes are dis- 1424 REPORT OF THE CHIEF'OF ENGINEERS, U. S. ARMY, 1957 patched regularly to 61 additional receivers, the latter being pril marily official. Numerous other tabulations and compilation of data in the charting, geodetic, hydraulic, and hydrologic fields are posted currently for use in answering the large number of inquiries for such data received each year. The following work was accomplished during the fiscal year in connection with various international boards and committees: INTERNATIONAL LAKE SUPERIOR BOARD OF CONTROL Regular and systematic reports of pertinent water levels and recommendations regarding the regulation of Lake Superior as indicated by the current rule curve were furnished to the Board. INTERNATIONAL LAKE ONTARIO BOARD OF ENGINEERS AND WORKING COMMITTEE Representatives of the Lake Survey attended 12 meetings at various locations in Caliada and the United States to accomplish the missions of the Board and Working Committee.

LAWRENCE JOINT WORKING 'COMMITTEE ON RIVER GAGING The District Engineer, who is Chairman of the United States Section of the Committee, made an inspection of the St. Lawrence River construction automatic gages with the Committee, and his U. S. LAKE SURVEY 1425 representative attended one other meeting of the Committee. A representative of the Lake Survey cooperated with the Hydro- Electric Power Commission of Ontario in a joint inspection of the construction automatic gages. Monthly spot checks were made of the reduction of the construction automatic gage records by the Hydro-Electric Power Commission of Ontario. Preparation of two progress reports of the Committee was coordinated with the Canadian Section. COORDINATING COMMITTEE ON GREAT LAKES BASIC HYDRAULIC AND HYDROLOGIC DATA AND SUBCOMMITTEES The Chief Technical Assistant of the Lake Survey serves as a member of this committee. Three meetings of the committee were held during the year. Members of the engineering staff of the Lake Survey serve on each of the three subcommittees appointed by the coordinating committee. (1) Lake Level Subcommittee. The United States member of the subcommittee attended two of the three meetings of the coordinating committee and one meeting of the subcommittee. Work was accomplished on the procedure to be followed in the adjustment of past water levels and on the establishment of the methods to be used in the recording of future water levels. (2) River Flow Subcommittee. The United States member of the subcommittee attended two meetings of the coordinating committee. An interim report on St. Lawrence River flows was compiled, reproduced, and distributed to the members of the coordinating committee. (3) Vertical Control Subcommittee. The United States mem- ber of the subcommittee attended two meetings of the coordinating committee and three meetings of the subcommittee. The work of the subcommittee consisted mainly of studies of the movement of the earth's crust. 2. EXAMINATIONS AND SURVEYS The cost of work during the fiscal year for special studies in connection with the survey report on Great Lakes wafer levels was $74,092. The unexpended balance of $8,028 at the end of the fiscal year plus an additional $5,500, or a total of $13,528, can be profitably expended during fiscal year 1958 for continuation of the study.

Morro Bay is on the Pacific coast, 110 miles south of Monterey Bay, 120 miles northwest of Santa Barbara Harbor, and nearly midway between San Francisco and Los Angeles. (See U. S. Coast and Geodetic Survey Chart No. 5387.) Existing project. The plan of improvement provides for 2 randomstone breakwaters, the upcoast breakwater extending 1,800 feet south by west from Morro Rock, and the downcoast breakwater extending west from the sandspit 1,399 feet, thence northwest 433 feet, a total distance of 1,832 feet; an entrance channel 16 feet deep and 350 feet wide; the Navy channel 16 feet deep, ranging in width from 350 feet to 800 feet from the entrance channel to the town of Morro; Morro channel from the town of Morro to the lower bay, 12 feet deep and generally 150 feet wide; a stone dike extending from Morro Rock to the mainland, a dis- tance of 1,600 feet; and a quarry-waste revetment levee extending for a. distance of 6,930 feet along the waterfront at Morro, to retain marginal fills. The plane of reference is mean lower low water. The range between mean lower low water and mean higher high water is 4;7 feet. The extreme range is about 8.5 feet. The 'Federal first cost for new work for the completed project was $2,612,093 from Navy funds. The average annual Federal maintenance cost during the past 5 years was $132,843. The existing project, which was adopted by the River and fHarbor Act of March 2, 1945, authorized (1) improvements as set forth in House Document 283, 77th Congress, 1st session; and (2) further harbor development as desired by the Navy Depart- ment in accordance with the plans on file in the office of the Chief of Engineers. Local cooperation. Fully complied with. Terminal facilities. Facilities, which are adequate for existing commerce, comprise 640 feet of existing piers constructed by the Navy, 205 feet of piers and 95 feet of floating docks con- structed by San Luis Obispo County, 263 feet of floating docks constructed by California Division of Beaches and Parks, 893 feet of privately owned piers, and 1,532 feet of privately owned floating docks. Operations, and results during fiscal year. The following maintenance was completed: (1) Dredging the entrance channel, the Navy channel, and the Morro channel; (2) constructing a rock groin at the sandspit near the entrance channel; (3) filling RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1'429 the breach in the sandspit at the root of the south breakwater with the dredged material; and (4) making an afterdredging survey. The costs, from regular funds, were $465,582, comprising $464918 for maintenance performed by contract and $664 for maintenance performed by hired labor. Condition at end of fiscal year. The existing project was com- pleted in 1946. The downcoast breakwater and the stone dike connecting Morro Rock and the mainland were completed in 1942; the retaining levee, the marginal fills along the waterfront, and the channel to the lower bay, in 1944; and the upcoast (Morro) breakwater, in 1946. Morro breakwater, which is subject to pounding by heavy seas, is rapidly deteriorating; and the south breakwater is in need of minor repairs. The navigation channels were dredged to project dimensions in August 1956. The project was in usable condition at the end of the fiscal year.

SANTA BARBARA HARBOR, CALIF. Location. Santa Barbara Harbor is on the Pacific coast, 90 miles northwest of Los Angeles Harbor and 320 miles' stgue-t of San Francisco Harbor. (See U. S. Coast and Geodetic Survey Chart No. 5261.) 1430 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Existing project. The plan of improvement provides for main- tenance by dredging of depths existing in 1934 in the harbor formed by the breakwater constructed by local interests and permits the maintenance of the harbor by means of a fixed sand- intercepting plant to be provided and operated by and at the expense of local interests; the United States to make available for the operation of the plant an amount not exceeding $30,000 annually, whenever funds are allotted for such purpose, provided that there shall be deducted from such funds the actual cost of harbor maintenance found necessary if and when the intercepting plant has been installed. The plane of reference is mean lower low water. The range of tide between mean lower low water and mean higher high water is 5.4 feet.- The extreme range is about 10 feet. The average annual Federal maintenance cost during the past 5 years was $37,725. The existing project was authorized by the following: Acts Work authorized Documents Aug. 30, 1935 Maintenance by dredging of the present depths into Senate Committee print, 73d the harbor formed by the breakwater constructed Cong., 2d sess. by local interests. Mar. 2, 1945 Permits maintenance by means of a fixed sand-inter- H. Doc. 348, 77th Cong., 1st sess. cepting plant to be provided and operated by and (contains latest published map). at the expense of local interests, the United States to contribute to operating expense an amount not to exceed $30,000 annually, whenever funds are allotted therefor, the funds thus contributed to be reduced by actual cost of harbor maintenance if and when the intercepting plant has been installed. Prior to adoption by Congress, the work was authorized by the Public Works Administration. Local cooperation. No specific local cooperation is required. However, $462,986 of non-Federal funds made available by local interests have been spent as follows: $450,322 to cover excess cost of depositing dredged material on the beach, over the estimated cost of similar dredging with disposal at sea; and $12,664 for dredging in the vicinity of the pier formerly owned by the Navy. The city of Santa Barbara has entered into a contract with the United States to substitute, in lieu of the fixed sand-intercepting plant, a movable dredge to work within the protected area to shape the shoal resulting from the travel of sand around the breakwater so as to provide added protection within the harbor and to pump the surplus sand and future accretions from the harbor area to the downcoast beaches. The city will provide and operate a dredge of sufficient capacity to maintain an entrance channel into the harbor with a minimum depth of 15 feet and a minimum width of 300 feet. Subject to the availability of operation and mainte- nance funds, the United States will reimburse the city on or before June 30 of each fiscal year, the sum not to exceed $30,000 toward the actual cost of condition surveys and operation of the dredge. This contract, dated March 6, 1956, was executed March 22, 1956, to be effective as of July 1, 1956. Terminal facilities. Terminal facilities consist of a wharf RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1431 2,200 feet long, a pier 335 feet long, and a landing float and mooring facilities for small craft. The wharf, which is equipped with a warehouse, is used for general cargo and for servicing fishing boats. The pier, which was owned by the Navy, is now operated by the city of Santa Barbara. Facilities are adequate for existing commerce. Operations and results during fiscal year. Condition surveys and maintenance-dredging payroll reports submitted by the city of Santa Barbara were audited, and the city of Santa Barbara was reimbursed under the terms of the maintenance-dredging contract. The costs, from regular funds, were $30,680, comprising $30,000 for maintenance performed by contract and $680 for maintenance performed by hired labor. Condition at end of fiscal year. The city of Santa Barbara has submitted evidence that it has maintained an adequate entrance channel into the harbor.

S. ARMY, 1957 3. PORT HUENEME HARBOR, CALIF. Location. Port Hueneme Harbor is on the coast of California, 65 miles northwest of Los Angeles Harbor and 345 miles south of San Francisco. (See U. S. Coast and Geodetic Survey Charts 5007 and 5202.) Existing project. The plan of improvement provides for es- tablishment of a harbor for light-draft vessels on the coast of southern California about a mile northwest of the existing harbor of Port Hueneme and for construction of shore-protection works. Ventura County, the sponsor of the project, requested modification of the document plan of harbor improvement to utilize more land now unimproved and less subdivided land and submitted a modified plan that was adopted and approved by the district engineer. This plan, which provides facilities for berthing and servicing about 500 small craft and commercial fishing boats at approxi- mately the same site as that under the document plan, provides for an entrance channel 20 feet deep, 300 feet wide, and about 1,650 feet long-protected by two parallel jetties about 1,300 feet long; an irregularly shaped entrance basin 20 feet deep and 1,750 feet long, and ranging in width from 300 to 750 feet; an inner basin 10 feet deep, 900 to 1,400 feet wide, and 1,200 to 2,000 feet long; a 10-foot-deep basin extending northward with a width of 250 to 100 feet and a length of 950 feet along the east side of the inner basin; the deposition of the dredged material (about 3,667,000 cubic yards) to restore the downcoast shoreline; a 2,300-foot-long offshore breakwater placed to form a sand trap in conjunction with the entrance jetties; and initial and biennial dredging of about 1,600,000 cubic yards of material from the sand trap and placing that material to restore and maintain the downcoast shoreline. The plane of reference is mean lower low water. The mean tidal range in this area is 3.7 feet; the diurnal range is 5.4 feet; and the extreme range, about 10.5 feet. The latest (1957) approved estimate of Federal first cost of new work on the project as modified is $7,160,000. The existing project was adopted by the River and Harbor Act of :September 3, 1954 (H. Doc. 362, 83d Cong., 2d sess.). A map of the modified plan is contained in "Design Memorandum No. 1, General Design for Harbor and Shore Protection Works Near Port Hueneme, California," prepared by the United States Army Engineer District, Corps of Engineers, Los Angeles, under date of May 1957. Local cooperation. Local interests are required to provide with- out cost to the United States all lands and rights-of-way properly cleared, access roads, and relocation of utilities necessary for construction and maintenance of the improvement; to provide adequate facilities for berthing, servicing, and maintaining small craft, open to all on equal terms; to establish a public body empowered to regulate the use and development of the harbor facilities; to acquire and hold in the public interest lands border- ing the harbor to a width sufficient for proper utilization of the RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1433 harbor; to maintain and operate all necessary harbor facilities except those parts of the project that are constructed by the United States; to eliminate and prohibit pollution of the bathing beaches affected; to hold and save the United States free from all damages due to the construction and maintenance of the im- provement; and to make fish-cannery sites available and .to encourage the construction of canneries by private interests. The biennial dredging and bypassing of beach material is to be continued at Federal expense only so long as Federal ownership' or use of the lands and improvements necessitates such protection. Terminal facilities. There are no existing terminal facilities at th6 site of the authorized harbor. Operations and results during fiscal year. Work on the general design memorandum for the modified plan was completed. The costs, from regular funds, were $11,130 for new work performed by hired labor. Condition at end of fiscal year. No construction work has been accomplished. The general design memorandum will be submitted in July 1957. Total costs for the existing project to June 30, 1957, were as follows: Costs Funds New work Maintenance Total funds------------------------------ Regular funds $58, 211 ------------- 211 ................. $..............................58, $5,211 $58, Total, Federal funds----- "---------, ------ 258,211 ._._-,------ 58,211 Other fnd ~, --- --------- i------------- ---- ----- -- -- -------- _ -- _ Total, all funds ------------------- . 58, 211 -------------------- 5.8, 211 Cost and financial statement Fiscal year ending June 30 Total to June 80, 1957 1958 1954 1955 1956 1957 une 0, 19 New work: Appropriated-----------------........

PLAYA DEL REY INLET AND HARBOR, VENICE, CALIF.: Location. Playa del Rey is on Santa Monica Bay on the coast of California, 20 miles northwest of Los Angeles Harbor and 410 miles southeast of San Francisco Bay. (See U. Coast and Geodetic Survey Charts 5101 and 5144,) 1434 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Existing project. The plan of improvement provides for es- tablishment of a harbor for light-draft vessels at Playa del Rey, on the coast of southern California. Los Angeles County, the sponsor of the project, requested modification of the document plan because the county believes that the large central water area uses a larger part of the Marina site than is necessary for navi- gation; that:the side basins have narrow entrances that will re- tard water circulation, causing fouling of water in the basins; that greater use of the area available is economically desirable owing to high cost of acquisition; that the central entrance channel isolates a large section of beach between it and Ballona Creek; and that several schools and colleges in the tributary area are interested in shell racing and no straight stretch of water of the required length is provided. The modified plan, which replaces the document plan, was approved by the Chief of Engineers on June 29, 1956. This plan, which provides for mooring 6,200 small craft and fow parking 2,000 trailer-mounted craft, consists of an entrance channel 5,190 feet long, 700 feet wide and 20 feet deep adjacent to the north jetty of the Ballona Creek flood-channel outlet pro- tected by 2 randomstone jetties about 2,000 feet long. The exist- ing north Ballona Creek jetty would be extended about 750 feet to function as the south jetty of the entrance channel and as a barrier between the flood channel and entrance channel; a new jetty about 2,000 feet long would be located at the north side of the entrance channel; a main interior channel about 950 feet wide, 12 to 15 feet deep, and about 5,010 feet in prolongation of the entrance channel; and 8 side basins ranging in length from about 2,400 to about 1,200 feet, 600 feet wide with intervening moles 354 feet wide. All basins would be dredged to a depth of 10 feet, except basin A, which would be dredged to 15 feet. The dredged material, amounting to about 14,000,000 cubic yards, is to be utilized for construction of the moles and for deposition on adjacent lowlands and beaches. Federal participation is limited by the authorizing act to 50 percent of the cost of the entrance jetties, entrance channel, and interior main channel. The plane of reference is mean lower low water. The mean tidal range is 3.7 feet, the diurnal range is 5.6 feet, and the extreme range is about 10.5 feet. The latest (1957) approved estimate of first cost of new work on the project as modified is $7,680,000, of which $3,840,000 would be borne by local interests and $3,840,000 by the United States. The existing project was adopted by the River and Harbor Act of September 3, 1954 (H. Doc. 389, 83d Cong., 2d sess.). A map of the modified plan is contained in "Design Memorandum No. 1, General Design for Playa Del Rey Inlet and Harbor, Venice, Calif.," prepared by the United States Army Engineer District, Corps of Engineers, Los Angeles, under date of November 1956. Local cooperation. Local interests are required to (a) con- tribute 50 percent of the cost of constructing the entrance jetties, RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1435 dredging the entrance and main channels, and revetting the banks adjoining the entrance channel--all of which work is to be per- formed by the United States; (b) provide without cost to the United States all rights-of-way necessary for construction and maintenance of the improvement and supply suitable spoil-disposal areas for initial work and subsequent maintenance when and as required; (c) secure and hold in the public interest the lands bordering on the proposed development to a width sufficient for proper functioning of the harbor; (d) remove and relocate all interfering facilities, including oil wells, and relocate and con- struct public utilities as required; (e) construct bulkheads or stone revetments on the side and end slopes of the basins and moles; (f) provide for vacating or relocating roads and high- ways; (g) clear all structures and improvements from the rights- of-way required for the proposed construction by the United States; (h) relocate the tide gates, which connect the main Venice canal with the Ballona Creek flood-control channel, from the right bank of the flood-control channel to the north bank of the entrance channel; (i) provide adequate berthing facilities and other facilities for small craft; (j) provide adequate parking areas; (k) establish a public body to regulate the use and develop- ment of harbor facilities, which shall be open to all on equal terms; (1) dredge or bear the actual cost of dredging the side basins; (m) maintain and operate the entire project except the aids-to-navigation, the entrance jetties, the stone revetments con- structed by the United States, and the project depths in the entrance and main channels; (n) hold and save the United States free from damages due to the construction and maintenance of the improvement; (o) agree that construction of a project as recommended shall not relieve local interests of responsibility for stabilization of the beach fill at Santa Monica (see Public Law 780, 83d Cong., 2d sess., approved Sept. 3, 1954; and H. Doc. 277, 83d Cong., 2d sess., titled "Appendix II, Coast of California, Point Mugu to San Pedro Breakwater, Beach Erosion Control Study"); and (p) relocate that part of the Venice Sewer that crosses the proposed harbor site as soon as possible, to prevent unreasonable delay in the completion of the project. Terminal facilities. No terminal facilities exist at the site of the authorized harbor.

REDONDO BEACH HARBOR, CALIF. Location. Redondo Beach Harbor is on'the Pacific coast in the southern (downcoast) part of Santa Monica Bay, about 18 miles by sea northwest of Los Angeles and Long Beach Harbors and about 417 miles southeast of San Francisco Bay. (See U. S. Coast and Geodetic Survey Charts 5101 and 5144.) Existing project. The plan of improvement provides for recon- struction of about 1,455 linear feet of the existing 2,400-foot stone breakwater, construction of a 2,830-foot extension of the existing breakwater, and construction of a south breakwater 600 feet long; and for maintenance of the entire existing breakwater as recon- structed, the breakwater extension, and the south breakwater. The plane of reference is mean lower low water. In Santa Monica Bay, the mean tidal range is 3.8 feet; the diurnal range 5.6 feet; and the extreme range, about 10.5 feet. RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1437 The latest (1957) approved estimate of Federal first cost of new work is $5,120,000. The existing project was adopted by River and Harbor Act of May 17, 1950 (H. Doc. 303, 81st Cong., 1st sess.). The project document contains the latest published map. Local cooperation. Local interests are required to provide, through a competent and duly authorized public body, all lands and rights-of-way necessary for construction and maintenance of the proposed improvements, including transfer of ownership of the existing section of the breakwater to the United States; to construct a quay wall along the land side of the harbor between the existing breakwater and the vicinity of Beryl Street; to dredge the harbor area a least depth of 12 feet below mean lower low water; to deposit the dredge spoil landward of the quay wall and in the eroded area south of the wall; to construct an access trestle, pier, slips, and all other facilities necessary for adequate berthing, servicing, maintaining, and supplying small craft; to maintain the specified depth in the harbor area and maintain and operate the harbor facilities, except the breakwater, with such facilities available to all on equal terms; and to hold and save the United States free from responsibility for any effects of the improvement on adjacent shorelines and from any damages due to construction and maintenance of the harbor improvements. Satisfactory assurances of local cooperation, in compliance with the pertinent act of Congress, were submitted by the city of Redondo Beach. The bill of sale covering the existing breakwater and a perpetual easement over the lands involved have been supplied by the city of Redondo Beach. Terminal facilities. The only existing commercial terminal facility is the Monstad pier. This pier is privately owned. It is 20 feet wide and extends seaward about 300 feet to a depth of 15 feet below mean lower low water. Facilities are considered adequate for existing commerce. Operations and results during fiscal year. Project construc- tion, which had been started under a continuing contract in May 1956, was continued, as follows: Reconstruction of the existing breakwater was completed, the south breakwater was completed, and the extension of the existing breakwater was initiated. The costs, all from regular funds, were $2,220,590, comprising $2,- 219,822 for new work performed by contract and $768 for new work performed by hired labor. Condition at end of fiscal year. Reconstruction of the existing breakwater was started in May 1956 and was completed in Octo- ber 1956. The south breakwater was started in November 1956 and was completed in January 1957. The extension of the exist- ing breakwater was started in October 1956: about 2,000 feet of substructure and 1,500 feet of superstructure have been com- pleted. The project as a whole is about 49 percent completed. Total costs for the existing project to June 30, 1957, were as follows: 1438 REPORT OF THE CHIEF OF ENGINEERS, U. S.

LOS ANGELES AND LONG BEACH HARBORS, CALIF. Location. Los Angeles and Long Beach Harbors are on the Pacific coast, 410 miles southeast of San Francisco Harbor and 96 miles northwest of San Diego Harbor. (See U. S. Coast and Geodetic Survey Chart No. 5147.) Previous projects. Los Angeles Harbor. There was no project for the outer harbor prior to the existing project. Original project for the inner harbor was adopted by the River and Harbor Act of March 3, 1871, and modified by the River and Harbor Acts of March 3, 1881, August 2, 1882, June 3, 1896, June 13, 1902, June 25, 1910, July 18, 1918, and March 3, 1925. Long Beach Harbor. There was no previous project. For further details, see page 1977 of Annual Report for 1915 and page 1646 of Annual Report for 1938. Existing project. The plan of improvement provides for a stone breakwater 11,152 feet long (San Pedro breakwater) ex- tending eastward from Point Fermin; for a stone-and-earth de- tached breakwater 18,500 feet long (middle breakwater); for a stone-and-earth detached breakwater 13,350 feet long (Long Beach breakwater) ; for maintenance of the original Long Beach breakwater south of the outer end of pier A (now an integral part of pier A as extended) ; for an entrance channel 1,000 feet wide and 40 feet deep to outer Los Angeles Harbor, with a turning basin 3,500 feet long and 1,500 feet wide of the same depth oppo- site the end of pier 1, and enlargement of the entrance to the inner harbor by dredging to a depth of 35 feet a triangular area at the junction of the inner harbor with this turning basin; for RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1439 irregular anchorage areas (areas A and B) 40 feet deep adjacent to the 40-foot-depth entrance channel; for an inner-harbor channel (Los Angeles channel) 35 feet deep and 1,000 feet wide, with a turning basin at its north extremity 35 feet deep; for a channel (East Basin channel) 35 feet deep and 650 feet wide extending from the turning basin to slip No. 5; for a channel (Cerritos channel) 35 feet deep and 400 feet wide from slip No. 5 to a turning basin in Long Beach inner harbor; for a turning basin 35 feet deep in Long Beach inner harbor; for an entrance channel to Long Beach inner harbor 35 feet deep and 300 to 500 feet wide; for a settling basin at the mouth of the Los Angeles River diversion channel, the dredged material to be deposited on the beaches eastward therefrom to Belmont pier; for a silt-diversion channel (Los Angeles River) for the protection of Los Angeles and Long Beach Harbors; and for maintenance of the entire project except the silt-diversion channel. Dredging in East Basin was authorized as a modification of the existing project by act approved September 3, 1954. Local interests have dredged about 1,290,000 cubic yards of material from the basin by using their own funds for which they were re- imbursed by the Federal Government. Approximately 700,000 yards of material remain to be dredged by the Federal Government. The plane of reference is mean lower low water. The range of tide between mean lower low water and mean higher high water is 5.5 feet. The extreme range is about 10 feet. The latest (1957) approved estimate of Federal first cost of new work for the existing project is $31,322,000, including $962,000 for dredging in East Basin as a modification of the existing project. This estimate does not include the cost of constructing 6,000 feet of the middle breakwater by the Navy Department. The average annual Federal maintenance cost during the past 5 years was $10,115. The last maintenance dredging was ac- complished in April 1946 at a cost of about $183,200. Rehabili- tation of the 12,500-foot middle-breakwater section constructed by the Corps of Engineers was accomplished in December 1947 at a cost of about $786,690. Local cooperation. The River and Harbor Act of July 3, 1930, requires that local interests take the following action: (1) cede to the United States, in lieu of that part of the military reservation at Reservation Point that will be required for widening the main entrance channel, an equivalent area to the east, adjoining the present Federal holding; and (2) dredge, at local expense, a portion 200 feet in width for the proposed 30-foot channel along the eastern, northern, and western sides of West Basin. The River and Harbor Act of August 30, 1935, requires local interests to dredge East channel and berths adjacent to pier 1 to a depth of 40 feet. The River and Harbor Act of October 17, 1940, requires no local cooperation except that, if local interests desire to use dredged material to reclaim land or to build up beaches in addition to that recommended therein, the cost in excess of the cheapest 1440 REPORT OF THE CHIEF OF ENGINEERS, U.

The city of Long Beach has supplied the Government with the sum of $335,575 to pay the increased cost of depositing dredged materials at desired locations. All conditions of local cooperation have been fully complied with. RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1441 In addition to the Federal project requirements, the cities of Los Angeles and Long Beach have expended approximately $100,000,000 and $60,000,000, respectively, for harbor improve- ments and facilities. Terminal facilities. In Los Angeles Harbor, there are 75,338 linear feet of wharves, of which 67,677 linear feet are owned by the city and 7,661 linear feet are owned by private interests. Facilities are considered adequate for existing commerce. In Long Beach Harbor, there are 53,541 linear feet of wharves and bulkheads, of which the city owns 31,530 linear feet (22,562 linear feet of completed wharves and quays, 5,293 linear feet of usuable bulkheads, and 3,675 linear feet of wharves and bulkheads to be completed in 1957) ; of which the Federal Government owns 15,470 linear feet; and of which 6,541 linear feet are owned by private interests. Facilities are considered adequate for existing commerce. Operationsand results during fiscal year. Condition and opera- tion studies of the harbors were accomplished, and reimbursement was made to the city of Los Angeles for dredging completed by the city in July 1953. The costs, all from regular funds, were $494,284, comprising $485,000 for new work performed by con- tract and $9,284 for maintenance performed by hired labor. Condition at end of fiscal year. The existing project was completed in 1949 except for dredging of East Basin. The 11,152-foot San Pedro breakwater was completed in 1912; the silt-diversion works, in 1923; the Los Angeles inner-harbor channels and turning basin, in 1931; the Long Beach entrance channel, in 1932; the Los Angeles Harbor entrance channel, in 1937; and the outer-harbor turning basin, in 1939. The 18,500- foot (middle) breakwater, comprising 12,500 feet built by the Corps of Engineers and 6,000 feet built by the Navy, was com- pleted in 1942. The 13,350-foot (Long Beach) breakwater was completed in 1949. Dredging from the settling basin at the mbtUth of the Los Angeles River diversion channel was completed in 1946. Dredging of areas A and B was completed in February 1949.

Newport Bay Harbor is on the Pacific coast, 24 miles southeast of Los Angeles-Long Beach Harbors, and 72 miles north- west of San Diego Harbor. (See U. S. Coast and Geodetic Survey Chart No. 1508.) Existing project. The plan of improvement provides for rub- blemound entrance jetties, 900 feet apart, 1,620 and 2,860 feet in length on the east and west sides of the channel, respectively; an entrance channel 20 feet deep and 500 feet wide; a main channel 20 feet deep, 700 feet wide just inside the entrance, narrowing to a general width of 350 feet; an anchorage area 20 feet deep, ap- proximately 3,800 feet long, and ranging in width up to 520 feet on the north side of the main channel in the eastern end of the bay; an anchorage area 20 feet deep, approximately 5,200 feet long, and ranging in width up to 600 feet on the south side of the main channel in the eastern end of the bay; a yacht-anchorage area 15 feet deep, 1,200 feet wide, and 1,700 feet long on the south side of the main channel midway of the bay; the Newport channel 15 feet deep, approximately 6,000 feet long, and ranging in width up to 330 feet; a turning basin 20 feet deep, approximately 2,000 feet long, and ranging in width up to 1,000 feet at the western RIVERS AND HARBORS- LOS ANGELES, CALIF., DISTRICT 1443 end of the bay; and a depth of 10 feet in the remainder of the main bay area. Excepting improvements authorized in the River and Harbor Act approved March 2, 1945 (i. e., widening the 20-foot-deep main channel from a general width of 200 feet to a general width of 350 feet and to a width of 300 feet just inside the entrance, deepening Newport channel to 15 feet over a width ranging up to 330 feet, and dredging two anchorages to a depth of 20 feet), all work de- scribed in the preceding paragraph was recommended by the Chief of Engineers to the Secretary of War (Secretary of the Army) under date of September 25, 1933, and was authorized by the Public Works Administration June 15, 1934, at a total estimated cost of $1,835,400 for new work, of which amount local interests were required to contribute one-half. The plane of reference is mean lower low water. The range between mean lower low water and mean higher high water is 4.3 feet. The extreme range is about 10 feet. The latest (1957) approved estimate of Federal first cost of new work is $1,974,000, comprising $797,000, the Federal first cost of new work authorized by the Public Works Administration, and $1,177,000 (revised 1957), the Federal first cost of new work authorized by the River and Harbor Act of March 2, 1945. The average annual Federal maintenance cost during the past 5 years was $1,957. The last major maintenance work consisted of repairs to the entrance jetties in November 1948 at a cost of $35,000. The existing project was authorized by the following: Acts Work authorized Documents Aug. 26, 1937 Maintenance of the work authorized by the Public Senate Commerce Committee Works Administration. print, 75th Cong.

The improvements authorized by the River and Harbor Act of March 2, 1945, are subject to the conditions that local interests contribute $255,000 to the first cost, and that re- sponsible local agencies agree to furnish without cost to the United States suitable areas for the disposal of dredge spoil for the initial work and subsequent maintenance when and as required and to hold and save the United States free from damages resulting from the improvements. These conditions of local cooperation have not been complied with. Local interests state that they expect to be able to guaran- tee the $255,000 as soon as Federal funds become available. All prior conditions imposed by the Public Works Administration and by the River and Harbor Act of August 26, 1937, are fully complied with. In addition to the Federal project requirements, the city of New- port Beach and Orange County have expended for dredging and jetty work the sum of $2,662,545 since 1916. Private interests have spent $683,000 for dredging and other harbor work, making 1444 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 a total expenditure of $3,345,545 for harbor improvements by local interests. Terminal facilities.

The River and Harbor Act of July 3, 1930, provides that, before any work is undertaken on the turning basin, local interests shall furnish necessary disposal areas and give as- surances satisfactory to the Secretary of War and Chief of Engi- neers that they will deepen areas adjacent to the municipal piers to a depth of 35 feet; and that, before any work is undertaken on the channel to Chula Vista, local interests shall contribute $10,000 in cash. These conditions have been complied with, except in the case of the channel to Chula Vista (one of the inactive parts of the project). The modification of the project in the act of October 17, 1940, is subject to the provision that the Chief of Engineers may direct the disposal of dredged materials on lands not under Federal ownership, provided that local interests reimburse the United States for the cost involved in excess of the cost of disposal by the most economical method and hold and save the United States free from claims for damages resulting from such disposal. This requirement was accepted by resolution of the city of Coronado and RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 1447 approved by the Chief of Engineers. The River and Harbor Act of March 2, 1945, requires no local cooperation. Terminal facilities. In San Diego Harbor, there are 42,100 linear feet of wharves, exclusive of Government-owned wharves, of which 20,445 linear feet are municipally owned; and 21,655 linear feet, privately owned. In addition, there are 2 wharves at Coronado and 1 Government-owned wharf at North Island. Facilities are being expanded to meet increased commerce. Operations and results during fiscal year. Condition surveys and operation studies were made. The costs, all from regular funds, were $9,343 for maintenance performed by hired labor. Condition at end of fiscal year.

West Basin Bridge is over the navigable entrance to West Basin, Los Angeles Inner Harbor, Calif. (See U. S. Coast and Geodetic Survey Chart 5147.) Existing project. The bridge is owned by the Southern Pacific Company and is operated by the Harbor Belt Line Railroad, which handles all railroad freight in the Los Angeles Harbor area. The bridge, authorized in 1911, is a steel, trunion-type, single-leaf bascule bridge having a span of 180 feet, with fixed timber ap- proaches on both sides. The channel under the bridge is about 30 feet deep. The bridge has been determined to be unreasonably obstructive to navigation and the owner has been ordered by the Secretary of the Army to remove the entire bridge, including dolphins and ap- proach trestles, channelward of the established pierhead lines, in accordance with the Truman-Hobbs Act, which requires the Government to share that part of the cost of removal that is at- tributable to the needs of navigation, with due regard to the sal- vage value and to the evaluated useful life already enjoyed by the owner, both reduced to present worth from the end of the economic life of the various parts of the bridge. The bridge as a whole is obstructive to navigation and has ad- versely affected the movement of approximately 60,000,000 tons of general cargo, lumber, and petroleum since. 1931, when reliable reporting was begun. Since the keeping of records on marine accidents at the bridge was commenced (May 1921), there have been more than 200 marine accidents due to the existence of the bridge, the last acci- dent occurring on September 28, 1955. The bridge was damaged so badly that it was impossible to lower it after the accident. It now remains in a fully open position. The latest (1956) estimate of the Federal share of the cost to remove the bridge is $245,000. On April 24, 1957, $125,000 of this amount were revoked. The bridge will be removed under the provisions of the Truman- Hobbs Act, approved June 21, 1940 (Public Law 647, 76th Cong., ch. 409, 3d sess., H. R. 9381). Local cooperation. The bridge owner in accordance with law is required to prepare and submit to the Secretary of the Army, within 90 dayA after service of his order for removal of the bridge, 1452 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 19570 general plans and specifications to provide for the removal of the bridge for the Secretary's approval. After approval of such general plans and specifications, and within 90 days after notification of such approval, the bridge owner shall, in such manner as the Secretary of the Army may prescribe, advertise and take bids for the removal of the bridge. All bids, including any bid for all or part of the project, shall be submitted to the Secretary, together with a recommendation by the bridge owner as to the most competent bid or bids. At the same time, the bridge owner shall submit to the Secretary a written guaranty that the total cost of the project, including the cost of such work as is to be performed by the bridge owner and not in- cluded in the work to be performed by contract, shall not exceed the sum stated in the guaranty. The Secretary may direct the bridge owner to reject all bids and to take new bids or may authorize the bridge owner to proceed with the project by contract, or partly by contract and partly by the bridge owner, or wholly by the bridge owner. Upon such: authorization and fixing of the proportionate shares of the cost as provided in section 6, Truman-Hobbs Act, the bridge owner shall, within a reasonable time to be prescribed by the Secretary, proceed with the work of removal of the bridge as provided in section 7 of the aforementioned act. The requirements of local cooperation have been fully complied with. Operationsand results during fiscal year. Southern Pacific Co., owner of the bridge, has initiated its removal. Plans and specifi- cations prepared by the owner for the removal of the bridge, low bidder, and guaranty of cost were approved by the Secretary of the Army on March 25, 1957. Southern Pacific Co. entered into contract with Healy-Tibbits Construction Co. on April 16, 1957. Actual work of removal of the bridge was started in May 1957. No payment of Federal funds will be made until the project is completed. Condition at end of fiscal year. The contractor has started to remove the superstructure.

SANTA MARIA VALLEY LEVEES, SANTA MARIA RIVER BASIN, CALIF. Location. Santa Maria Valley levees would be loc.ated along the Santa Maria River and Bradley Canyon in Santa Barbara and San FLOOD CONTROLLOS ANGELES, CALIF., DISTRICT 1453 Luis Obispo Counties, Calif., about 60 miles northwest of the city of Santa Barbara. The improvements along the Santa Maria River would extend for about 17 miles from Fugler's Point (at the junction of the Cuyama and Sisquoc Rivers) to a point approxi- mately 600 feet downstream from the highway bridge at Guada- lupe. The improvements along Bradley Canyon would extend from the canyon mouth to the Santa Maria River. Existing project. The plan of improvement provides for levee and channel improvements along the Santa Maria River and along Bradley Canyon. The Santa Maria River levee and channel im- provements would consist of (a) a levee on the left bank com- mencing at Fugler's Point and extending downstream for about 17 miles to a point approximately 600 feet below the highway bridge at Guadalupe, (b) a levee on the right bank commencing about 11/4 miles below U. S. Highway No. 101 and extending downstream for about 5 miles to a point about 11/ miles above the Southern Pacific railroad bridge at Guadalupe, and (c) channel clearing from Fugler's Point to the Pacific Ocean. The Bradley Canyon levee and channel improvement would consist of about 1.9 miles of leveed channel to divert the floods of Bradley Canyon to the Santa Maria River. This channel, which would have a bottom width of 100 feet, would have a double levee system extending 2,600 feet upstream from the Santa Maria River and a single levee extending 7,500 feet upstream from the double levee system to the mouth of Bradley Canyon. The latest (1957) approved estimate of Federal first cost is $10,800,000. The improvement was authorized by the Flood-Control.Act of September 3, 1954. The levees would be a part of a comprehensive improvement, including the multiple-purpose Vaquero Reservoir that is authorized for construction on the Cuyama River by the Bureau of Reclamation. (See H. Doc. 400, 83d Cong., 2d sess.) References to published articles not previously reported. Southwest Builder and Contractor (May 8, 1953, vol. 121, No. 19, p. 42). Local cooperation.

The act of July 3, 1930, requires that local interests provide free of cost to the United States suitable areas for the disposal of dredged materials, and royalty-free stone for construction and repair of the jetties, together with suitable rights-of-way needed in transporting the stone to the jetties. These requirements have been fully complied with for work performed to date. The act of March 2, 1945, requires that local interests provide the necessary rights-of-way and easements for the construction and maintenance of the breakwater, including access thereto, and a suitable royalty-free quarry in the locality; and give assurances satisfactory to the Secretary of War that they will provide suitable public facilities and arrangements for the loading and unloading of vessels in Noyo Harbor. These require- ments have not been complied with. The act of June 30, 1948, requires that local interests establish a competent public body empowered to regulate the use and development of the port facilities, which shall be open to all on equal terms, and provided such public body (1) furnishes, without cost to the United States, all lands, easements, and rights-of-way necessary for construction of the improvement; (2) agrees to hold and save the United States free from damages resulting from construction and maintenance of the project; (3) reserves for spoil-disposal areas all presently unused lands adjacent to the lower 1.6 miles of the river and lying below an elevation of 16 feet above mean lower low water; (4) agrees to furnish, free of cost to the United States, easements over these areas for the deposit of spoil from the new work and maintenance dredging and for the construction thereon of im- pounding levees and to furnish royalty-free material for the con- struction of such levees, all when and as required; and (5) agrees to contribute to the United States funds equal to the Federal cost RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DIST. 1511 of constructing such levees as and when required. The Noyo Harbor district was established by the Board of Supervisors of Mendocino County on October 18, 1950, as an initial step in fulfilling the requirements of local cooperation. Terminal facilities. There are no facilities in the harbor proper. In the river above the harbor there are two piers and six fish receiving wharves, three of which have boat fueling stations thereon; five boat building and repair plants; one boat fueling and icing terminal; and a number of mooring facilities, all privately owned. These facilities are considered adequate, with the exception of mooring and berthing facilities for fishing boats. Improvement of the project as authorized will provide additional protected area for required facilities. Operations and results during fiscal year. As maintenance, engineering and design was accomplished by hired labor and 33,000 cubic yards of material were removed from the river channel by contract at a cost of $66,883. Condition at end of fiscal year. The project is about 15 percent complete. The work remaining to be done is the construction of the breakwater in Noyo Harbor and the extension of the channel one-half mile upstream to mile 1.15. The jetties, rock removal, and dredging of the entrance channel and approximately five- eighths of a mile of the river channel were completed in 1931. The controlling depths on the dates indicated were as follows: In April 1955, 10.5 feet at the entrance to the channel; in February 1957, 5.1 feet between the jetties, 7.0 feet to the green navigation light at the first curve (quarter-mile point), thence 4 feet through the completed portion of the project except for zero depth at the extreme end.

OAKLAND HARBOR, CALIF. Location. This harbor is on the eastern side of San Francisco Bay, opposite the city of San Francisco. The inner harbor is situated between the cities of Oakland and Alameda. (See U. S. Coast and Geodetic Survey Chart No. 5535.) Previous projects. Adopted by the River and Harbor Acts of June 23, 1874, June 13, 1902, and March 2, 1907. For further details, see page 1979 of Annual Report for 1915, page 1755 of Annual Report for 1921, and page 1674 of Annual Report for 1938. Existing project. This provides for an entrance channel to Oakland Outer Harbor, 35 feet deep from deep water in San Francisco Bay and 800 feet wide across the shoal southeast of Yerba Buena Island, thence narrowing to 600 feet at Oakland Mole; thence a channel and turning basin 35 feet deep and from 600 to 950 feet wide in the outer harbor to the Army Base. The project also provides for an entrance channel to Oakland Inner Harbor, 30 feet deep and 800 feet wide at the bayward end, narrowing to 600 feet wide at the ends of the Oakland jetties; a channel from the ends of the jetties 30 feet deep and 600 feet wide to the west end of Government Island, with additional widening to the pierhead line in front of the Grove and Market Street (formerly municipal) piers, and widening to within 75 feet of the pierhead line along the south side of the channel from Harrison Street eastward to harbor-line point 119 in Brooklyn Basin; a channel 30 feet deep and 500 feet wide through Brooklyn Basin; for dredging to a depth of 30 feet a triangular area about 2,700 feet long and of a maximum width of 300 feet at the western end of Brooklyn Basin; maintenance of a channel 25 feet deep and 300 feet wide at the north end of Brooklyn Basin; a turning basin at the east end of Brooklyn Basin 30 feet deep, 500 feet wide, and 1,200 feet long; a navigation channel in the tidal canal 30 feet deep and 275 feet wide from Brooklyn Basin to Park Street, thence 18 feet deep to San Leandro Bay; a total channel length of 81/2 miles from San Francisco Bay to San Leandro Bay. The project RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DIST. 1521 also includes parallel rubblemound jetties at the entrance to the inner harbor, a north jetty 9,500 feet long and a south jetty 12,000 feet long; and three highway bridges across the tidal eanal, two of which (at Park Street and High Street) have been replaced by local interests. The railroad and highway bridges at Fruitvale Avenue are being maintained and operated by the United States. All depths refer to mean lower low water. The range between mean lower low water and mean higher high water is 6 feet in the outer harbor and 6.3 feet in the inner harbor at the Park Street Bridge. The extreme range is about 11 feet. The project was completed in 1931 except for deepening the tidal canal above the Park Street Bridge to 25 feet. The cost of the completed work was $2,622,031, exclusive of contributed funds in the amount of $83,547 and of amounts expended on previous projects. The uncompleted portion of the project is to be re- studied. The cost of this portion was last revised in 1954,and was estimated to be $489,069. The average annual maintenance cost during the past 5 years was $223,721.

The act of January 21, 1927, as modified by the. act of March 2, 1945, requires that local interests contribute one-half the cost of the entrance channel (400 feet wide) to the outer harbor and that the future maintenance 'by, the United States -of the north channel in Brooklyn Basin be contingent upon the removal by local interests of all sewers emptying therein, or, in lieu of such removal, upon the contribution of one-half the cost of maintenance (H. Doc. 407, 69th Cong., 1st sess., and H. fDoc. 466, 77th Cong., 1st sess.). The first of the above requirements 1522 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY i 1957 has been fulfilled. The others have not been fulfilled. In com- pliance with a 1910 license issued by the Secretary of War pursuant to provisions of the act of June 25, 1910, local interests have replaced the bridges at Park Street and High Street and are operating and maintaining them. They operated and maintained a combined highway and railroad bridge at Fruitvale Avenue until 1942 when the California Court of Appeals ruled that it was illegal for the County of Alameda to use appropriated funds for the sole benefit of a private corporation. The Southern Pacific Railroad Co. operated trains over the combined bridge until June 1951 when a separate railroad bridge, constructed for its use by the Federal Government, was placed in operation. (The railroad and highway bridges at Fruitvale Ave. are maintained and operated by the United States.) Terminal facilities. In the inner harbor there are 64 wharves of which 36 are owned by the Port of Oakland, 7 shipyards, and numerous small boat moorings. In the outer harbor there are 5 wharves, owned by the Port of Oakland, and 2 privately owned ferry terminals. These facilities are exclusive of those owned by the United States and are considered adequate for existing commerce. Operations and results during fiscal year.

REDWOOD CITY HARBOR, CALIF. Location. Redwood City Harbor is on Redwood Creek, a tribu- tary of San Francisco Bay about 20 miles south of the city of San Francisco. The project works also include a channel in San Francisco Bay east of Point San Bruno. (See U. S. Coast and Geodetic Survey Chart No. 5531.) Previous projects. The original project was adopted by the River and Harbor Act of July 5, 1884, and modified by the River and Harbor Act of June 13, 1902. For further details, see page 1979 of Annual Report for 1915, and page 1672 of Annual Report for 1938. Existing project. This provides for a channel 500 feet wide and 30 feet deep across San Bruno Shoal in San Francisco Bay; a channel 300 feet wide and 30 feet deep to the vicinity of the confluence of West Point Slough and Redwood Creek, with a basin at that location 2,200 feet long and from 400 to 900 feet wide; thence a channel 400 feet wide, 30 feet deep, and approximately 1,300 feet long, flaring to a second turning basin approximately 900 feet wide, 1,700 feet long, and 30 feet deep; thence a channel 150 feet wide and 5 feet deep extending to Steinberger Slough. All depths refer to mean lower low water. The tidal range be- tween mean lower low water and mean higher high water is 6.9 feet at Point San Bruno and 7.9 feet at Redwood City. The extreme ranges are estimated to be 12 feet and 13 feet at the respective localities. The authorized channel across San Bruno Shoal is about 41/3 miles long. In the creek, the authorized deqp- water channel is 3.4 miles long including the basins, and the 5-foot channel extends to mile 4.3. 1524 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The latest approved estimate of cost for new work (1957) is $2,010,000, of which $1,890,000 is Federal cost and $120,000 is the amount contributed by local interests. The average annual maintenance cost during the past 5 years was $79,160.

Project name changed from Redwood Creek, Calif., to Redwood City Harbor, Calif. Local cooperation. Fully complied with for work performed to date. The act of August 30, 1935, requires that local interests furnish areas for disposal of dredged materials removed during maintenance. No local cooperation is required by the act of March 2, 1945, but local interests have voluntarily offered to provide necessary spoil-disposal areas and impounding works. The act of May 17, 1950, requires that the port of Redwood City give assurances satisfactory to the Secretary of the Army that it will (1) provide, without cost to the United States, all necessary land, easements, rights-of-way, and spoil-disposal areas with necessary impounding works, for the construction and subsequent maintenance of the project, when and as required; (2) hold and save the United States free from damages due to the construction and subsequent maintenance of the works; (3) arrange with responsible local interests to relocate, without cost to the United States, the municipal yacht harbor and provide new facilities at least equal to those now available; (4) maintain at its own expense the existing public terminal and construct and maintain, without cost to the United States, an additional public wharf, sufficient in size to accommodate a modern cargo vessel, located on the proposed extension of the project, with the understanding that all public terminals shall be open to all on equal terms. The board of port commissioners of the city of Redwood City has furnished resolutions of intent to comply with these requirements. Preliminary plans for relocating the municipal yacht harbor have been lcompleted. In addition, the port has expended in excess of $200,000 in recent years for additions and improvements to exist- ing municipally owned and operated shore facilities. In 1951 the Leslie Salt Co. placed in operation a multimillion dollar salt- production, storage, and bulk shiploading facility at the upper limit of the upstream turning basin authorized by the act of May 17, 1950. To provide access to the shiploading facility, they have dredged and are maintaining a small channel and turning basin within the area included in the authorized, but unconstructed, RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DIST. 1525 portion of the Federal project. The bulk loading facilities are available for public use through contractual arrangements with the Port of Redwood City. Terminal facilities. There are 3 municipally owned wharves, 4 privately owned wharves, a boat repair yard, a bulk salt-loading facility, and a pleasure boat mooring in Redwood City Harbor. Local interests have definite plans for additional facilities to accommodate anticipated increases in commerce. Operations and results during fiscal year. As maintenance, engineering and design, including a dredging survey, was ac- complished and 158,000 cubic yards of material were removed from the entrance channel and outer turning basin by the U. S. hopper dredge Davison at a cost of $76,678. In addition to the project maintenance, a reconnaissance and condition survey of a portion of the project was accomplished at a cost of $240. Condition at end of fiscal year. The existing project is about 20 percent complete. The work remaining to be done is the widening and deepening of the channel across San Bruno Shoa!,. and of the channel and turning basin in Redwood Creek as authorized by the act of March 2, 1945, and the channel and turning basin in Redwood Creek as authorized by the act of May 17, 1950. The controlling depths in the various channels on the dates indicated were as follows: March 1956, 28.5 feet in San Bruno Shoal Channel; December 1956, 25 feet in San Francisco Bay to the outer turtiing basin, and 21 feet in turning basin; May 1954, 10 feet to the municipal yacht harbor, and 3.5 feet to Steinberger Slough, except at extreme end of project where depth was 1.5 feet.

KAWAIHAE HARBOR, T. H. Location. This harbor is in Kawaihae Bay, adjacent to the town of Kawaihae, and is on the northwest coast of the island of Hawaii, approximately 45 miles northwesterly from Hilo, island of Hawaii. (See U. S. Coast and Geodetic Survey Chart No. 4166.) Existing project. This provides for an entrance channel 400 feet wide and approximately 2,900 feet long to a depth of 40 feet, a harbor basin 1,250 feet square to a depth of 35 feet;. and a protective breakwater with maximum crest elevation 13 feet above mean lower low water and approximately 4,400 feet long, of which 3,200 feet would be protected with heavy stone revetment. The plane of reference is mean lower low water. The range of tide between mean lower low water and mean higher high water is 2.1 feet, and the extreme range under ordinary conditions is 4.5 feet. The latest approved estimate of cost for new work (1957) is $6,830,000. The existing project was authorized by the River and Harbor Act of May 17, 1950 (H. Doc. 311, 81st Cong., 1st sess.). The latest published map is in that document. Loca cooperation. The River and Harbor Act of May 17, 1950, requires that local interests give assurances satisfactory to the Secretary of the Army that they will (1) furnish without cost to the United States all lands, easements, rights-of-way and spoil- disposal areas necessary for the construction and subsequent maintenance of the project, when and as :required, to include specifically properties landward of the harbor basin and break- water from the shoreline to the paved public highway; (2) hold 1534 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 and save the United States free from damages due to the construc- tion and subsequent maintenance of the project; (3) provide and maintain at their own expense adequate public terminal and transfer facilities open to all on equal terms; and (4) accomplish without cost to the United States all necessary alterations in water supply, sewerage, drainage, and other utilities. The Board of Harbor Commissioners of the Territory of Hawaii, by resolution adopted May 27, 1955, has indicated that it will comply with all requirements of local cooperation. The Legislature of the Territory, by Act 95 Session Laws 1947, authorized the Territorial Board of Harbor Commissioners to expend $1,000,000 for harbor facilities at Kawaihae, upon ap- proval and development of the project by the Federal Government. The Kohala Sugar Co. would abandon its wholly owned subsidiary, the Mahukona Terminals, Ltd., which represents a substantial investment, and is prepared to participate jointly with other sugar companies to finance the installation of bulk sugar handling facilities at Kawaihae. The Territory of Hawaii has acquired and conveyed to the Federal Government necessary quarry rights, and lands, easements, and rights-of-way, and has initiated preliminary engineering and design of required terminal facilities. By Act No. 136 of the 1953 session of the Territorial Legisla- ture, the Board of Harbor Commissioners was authorized to provide partial harbor improvements at Kawaihae at a cost of $500,000. Of this amount, $300,000 was authorized for dredging a channel and harbor basin and $200,000 was authorized for construction of terminal facilities and acquisition of lands and rights-of-way. The Territory of Hawaii has completed a channel 200 feet wide, 1,600 feet long, and 20 feet deep, and a small-boat basin 250 feet square and 10 feet deep to augment the Federal deep-draft harbor and to accommodate tugs, barges, and other small craft. Terminal facilities. There is a paved barge landing, approxi- mately 60 feet wide and 400 feet long, along the recently dredged Territorial Channel. The Territory of Hawaii has constructed a pier shed on the landing. A cattle corral was completed during the fiscal year. The old Kawaihae wharf, approximately 2,200 feet northwesterly from the new Kawaihae Harbor, is not being maintained. The existing facilities are owned and administered by the Territory of Hawaii and are open to all on equal terms. Present facilities are considered inadequate to accommodate exist- ing commerce and the increasing shipping needs of the western half of the island of Hawaii. Transpacific and inter-island commerce is expected to be adequately provided for upon comple- tion of terminal facilities on which preliminary engineering has been initiated by the Territory of Hawaii. Operations and results during fiscal year. As new work, ad- vance engineering and design was completed by hired labor at a cost of $1,684; and construction of causeways, dike, and revetment was initiated by contract at a cost of $667,342, including con- struction engineering and design by hired labor. The total project cost during the fiscal year was $669,026 for new work. RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DIST. 1535 Condition at end of fiscal year.

The Russian River rises in the Coast Range in north- western California, flows southerly for a distance of 87 miles, and then turns westerly to flow for 23 miles to the Pacific Ocean at Jenner, 60 miles northwest of San Francisco, Calif. (For the general location see U. S. Geological Survey map for the State of California.) Existing project. The authorized project provides for the con- struction of the initial stage of the plan of improvement consisting of Coyote Valley Reservoir on the East Fork of Russian River ap- proximately 0.8 mile above the mouth of that tributary near Ukiah, Calif., and channel stabilization works on the lower 97 1538 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 miles of the Russian River and on the lower reaches of several tributaries. The dam is an earthfill type with a crest length of 3,500 feet at elevation 784, mean sea level datum, and a height above the streambed of approximately 160 feet. A paved overflow spillway, having a fixed crest at elevation 764.8 and a crest length of 200 feet, will be located in an existing saddle approximately 0.6 mile upstream from the left abutment. Gated outlet works, located through the dam, will provide capacity to empty the flood control storage in about 4 days. The dam will control runoff from 105 square miles of drainage area and will create a reservoir hav- ing a capacity at spillway crest of 122,500 acre-feet, of which 48,000 acre-feet are reserved for flood control and the remainder for water conservation and siltation. The estimated cost of the principal features of the project is as follows: Estimated cost Project feature Lands and dam- Construction ages (including Total relocations) Coyote Valley dam and reservoir....----------- $10, 480, 000 $5, 649, 000 $16,129, 000 Channel improvement works--------------- 2,471,000 (1) 2, 471, 000 Total-------------------------------- 12, 951, 000 5, 649, 000 18, 600, 000 1 To be provided by local interests. The latest approved estimate of cost for new work (1957) is $18,600,000, of which $13,002,000 is Federal cost and $5,598,000 is the amount contributed by local interests. The project was authorized by the Flood Control Act approved May 17, 1950 (H. Doc. 585, 81st Cong., 2d sess. as modified by the Chief of Engineers).

Local cooperation. The improvements are subject to the condi- tion that prior to starting construction, local interests shall con- tribute the sum of $5,598,000 in cash in full payment of the conservation benefits, and shall (1) furnish free of cost to the United States all lands, easements, and rights-of-way necessary for the construction of the channel stabilization works; (2) make all necessary road and bridge revisions and utility alterations and relocations required for the channel stabilization works; (3) ad- just all claims concerning water arising from the construction and operation of the improvements; (4) hold and save the United States free from damages due to the construction works; (5) main- tain the channel stabilization works, after completion, in accord- ance with regulations prescribed by the Secretary of the Army; (6) prevent any encroachment on the stream channel which would interfere with the proper functioning of the improvements or lessen their beneficial effects; and, (7) enter into an agreement among themselves as to the method of operation of the reservoir for conservation subject to flood control priority. FLOOD CONTROL-SAN FRANCISCO, CALIF., DISTRICT 1539 Sonoma and Mendocino Counties formed legally constituted flood control acrd water conservation districts in 1949 as an initial step toward meeting the requirements of local cooperation. A successful bond election, held in Sonoma County on May 10, 1955, authorized a bonded indebtedness of $5,650,000 to provide for the full amount of the cash contribution required for the project and for costs and expenses incidental thereto. In addition, a bonded indebtedness of $8,500,000 was authorized to provide a local water distribution system. The Board of Directors of the Sonoma County flood control and water conservation district, by Resolu- tion No. SA 6847 dated May 25, 1955, guaranteed fulfillment of all local cooperation required for the project except that pertaining to the channel stabilization works to be constructed outside the boundaries of Sonoma County. The required cash contribution of $5,598,000 was made by the County of Sonoma to the Department of the Interior in full repayment of the conservation benefits of the project and transferred to the Department of the Army on March 5, 1956. On January 24, 1956, the voters of southern Mendocino County passed a $650,000 bond issue in support of Mendocino County's share of the project cost and approved the formation of the Russian River Flood Control and Water Conser- vation District, which has initiated action to provide the remain- ing items of local cooperation. In December 1956 Sonoma County was reimbursed $633,000 by Mendocino County for its share of the local cash contribution for the water-conservation benefits of the project.

Sacramento River rises in the Trinity Mountains in north-central California, flows in a general southerly direction about 374 miles and empties into Suisun Bay, an arm of San Francisco Bay, at Collinsville, Calif. (See U. S. Geological Survey topographic map of the Sacramento Valley, Calif.) Previous projects. The original project was adopted by the River and Harbor Act of March 3, 1875, and provided for im- provement of the low water channels in the Sacramento River and for snagging and construction of temporary wing dams in the Feather River, a tributary entering the Sacramento River about 16 miles above the city of Sacramento. The project was subse- quently modified by the River and Harbor Acts adopted August 2, 1882, December 21, 1889, July 13, 1892, and August 18, 1894. These modifications provided for dredging in the Sacramento and Feather Rivers and for restraining barriers (for mining debris) in the Yuba, Bear, and American Rivers, tributaries of the Sacra- mento River, as an aid to navigation; for improving navigation by repairing damages caused by floods; for a snag boat above Sacramento; removal of obstructions in the lower Sacramento River; further treatment of the Yuba River near and above the 1549 1550 REPORT OF THE CHIEF OF ENGINEERS, U. S.:ARMY, 1957 city of Marysville and improvement of the navigable channel of the Feather River; and for treatment of the Bear River and con- struction of a cutoff on the Feather River to avoid Shanghai Bend. For further details see page 1985, Annual Report for 1915, and page 1708, Annual Report for 1938.. Existing project. The project provides for construction of the: Sacramento River Deep Water Ship Channel from deep water in Suisun Bay to Washington Lake, 11/2 miles west of the Sacramento River at the city of Sacramento, a distance of 43 miles, construc- tion of a harbor and turning basin at Washington.Lake, and a connecting canal with navigation lock from the harbor to the Sacramento River. The project also provides for a shallow-draft channel ten feet deep at mean lower low water, 150 to 200 feet bottom width, from Suisun Bay to Sacramento, Calif.,; a distance of 60 miles; a depth of 6 feet at low water between Sacramento and Colusa, a distance of 85 miles; a depth of 5 feet at low water between Colusa and Chico Landing, a distance of 50 miles; and such depths as practicable between Chico Landing and Red Bluff, a distance of 52 miles. The deep water channel will be formed by widening and deepen- ing existing channels for the first 18 miles above Suisun Bay to 6 miles above Rio Vista and excavation of a new channel forthe remaining 25 miles to Washington Lake, to a depth of 30 feet at mean lower low water with a bottom width of 200 to 300 feet, including related confining embankments and such works as may be necessary to compensate for or to alleviate any possible detri- mental effects on salinity of Delta tidal channels which might result from the ship channel. The triangular harbor and turning basin will be formed by deepening and widening Washington Lake to a depth of 30 feet at mean lower low water, 2,400 feet by 2,000 feet by 3,400 feet, with provision for future enlargement. The construction of the 11/2 -mile long canal 13 feet deep and 120 feet wide between the harbor and the Sacramento River, together with a navigation lock 86 feet wide by 600 feet long, will provide for- the transfer of barges between the two different water surface elevations. A single leaf combination highway and railroad bascule bridge will cross the canal at the harbor end of the naviga- tion lock. Local interests will construct, operate,: and maintain an adequate public terminal with necessary utilities and rail and highway connections at the harbor. The deep-draft channel will provide access inland to Sacramento for oceangoing vessels and, in addition, Will also be used for large amounts of barge shipping because its length is shorter than that of the river and because the greater depth and slack water will: permit handling larger barges. It will serve an area covering northern California, southern Oregon, and' western' Nevada. These facilities will also be utilized by military installations in the area. Above Sacramento the results are to be obtained by removal of snags and concentration of the channel by dredging aind wing dams and by streamflow regulation by the Siaast Reservoir. The 10-foot channel below Sacramento was completed in 1931 RIYEV S AND HARBORS-SACRAMENTO, CALIF., DISTRIC: 1551 and the 6-foot channel between Sacramento and Colusa was com- pleted in 1946; these channels are to be maintained for local navi- gati n. Provision of the 5-foot depth between Colusa and Chico Landing (50 miles) has not been initiated. Construction of the 30-foot deep. water ship channel was initiated in July 1949 and is about 12 percent complete.

Doe. 142, 79th Cong, 24 ses. 1552 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Maintenance bank protection on the deep-draft channel was performed in 1952 and 1955, at a total cost of $187,840, to repair serious erosion along the deep-draft channel caused by tidal action and wave wash due to construction of the ship channel. The above cost will not be sufficient on an annual basis to properly maintain the deep-draft channel when construction is completed. The average annual maintenance cost for the shallow-draft channel during the past 5 years was $363,590, including the ex- penditure of $69,695 deferred maintenance funds. Exclusion of this $69,695 expenditure would reflect an average annual maintenance cost during the past five years of $349,650. Recommended modification of project. In House Document 1893, 64th Congres, 2d session, it recommended that Chico Land- ing, about 52 miles downstream from Red Bluff, be made the head of the improvement. Local cooperation. The improvement for the deep water chan- nel is subject to the condition that responsible local interests give assurances satisfactory to the Secretary of the Army that they will: (1) Furnish without cost to the United States all lands, ease- ments, rights-of-way, and spoil-disposal areas for the initial work and subsequent maintenance when and as required and make all necessary utility changes necessary for the construction of the project; (2) Construct, operate, and maintain at the Washington Lake basin an adequate public terminal with necessary utilities and rail and highway connections open to all one equal terms; and (3) Hold and save the United States free from any damages which may arise from construction, operation, and maintenance of the improvement. The Sacramento-Yolo Port District was formed under the laws of the State of California in April 1947, for the purpose of carry- ing out the required local cooperation. The Port District, by re- solution dated December 24, 1947, gave assurances that it would accomplish all requirements for local cooperation. These as- surances were accepted on February 3, 1948, by the Secretary of the Army. A total bond issue of $3,750,000 was authorized by the voters in the Port District in November 1947. Bonds in the amount of $1,750.000 were sold prior to 1956 and the proceeds used toward part of the project works. In November 1956 $1,000.000 in bonds were sold by the Port District, proceeds of which will be used by the District for acouisition of rights-of-way and for port facilities. In addition, the California State Legislature appropriated $750,000 in 1947 to assist the acquisition of necessary rights-of-way. The Sacramento-Yolo Port District has furnished all lands, rights-of-way, and easements required for project purposes to date, and, in addition, has acquired in fee all lands for the lock and bridge except that owned by the Sacramento Northern Railway. The Port District is actively negotiating for an easement through this property. RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1553 Total estimated costs for all requirements of local cooperation for lands, rights-of-way, utility relocations and modifications, and spoil disposal areas under terms of the project authorization, in- cluding required non-Federal contributions, amount to $3,100,000 (1957). In addition, total estimated costs for construction of the public terminal with necessary utilities and rail and highway connections at Washington Lake, required under terms of the proj- ect authorization, amount to over $5,000,000 (1957). About $1,150,000 (January 1957) have already been expended toward accomplishing this plan. A master plan covering development of terminal facilities has been prepared for the future development of the port. The port district has completed construction of a 500,000-bushel grain elevator, placed in operation in June 1950, together with necessary railroad, highway, and appurtenant facilities. The Port District currently has additional construction underway for expansion of storage capacity amounting to 375,000 bushels in three storage bins. These bins will increase the storage capacity about 74 per- cent and will be so located as to tie in with the ultimate completion of a tremendous shipside grain elevator. In addition to developments by the port district, the Farmers' Rice Growers Corp. has constructed a rice dryer, mill, and elevator designed for direct conveyor-belt connection with seagoing vessels, at an expenditure in excess of $2,250,000. A warehouse company has constructed and placed in operation two warehouses at a cost of $300,000 each. These facilities are served by the port belt railroad and by highway connections. The State of California has completed construction of the highway overpass entrance to the port terminal area at a cost of about $300,000. The current (1957) estimate of cost to local interests for terminal facilities is $5,000,000. The sum of $500,000 was advanced to the United States in June 1949, to accelerate construction, which has been returned to the port authority. Repayment of the last $200,000 was accomplished in fiscal year 1957. No local cooperation is required on the shallow-draft feature of the project. Terminal facilities. All of the piers, wharves, and docks at the port of Sacramento are open pile structures with timber decks, some of which are designed to meet the extreme high waters at flood stages. Eleven facilities are located along the east bank, or Sacramento side, of the river, and 10 are on the west bank at Broderick, West Sacramento, and points below. Of the 21 pier, wharf, and dock facilities at the port, nine are used for receipt of petroleum products, with 955 linear feet of berthing space; two are general cargo wharves, with 592 linear feet berth- ing space and 40,000 square feet of transit shed storage area; two are used for the receipt and shipment of sacked rice with 150 linear feet of berthing space; and one is receiving point for diesel oil used in the gas and electric powerplant with 130 linear feet of berthing space. Four facilities, providing 1,620 linear feet of 1554 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 berthing space and comprised mainly of floats, are used for moor- ing and servicing recreational craft; the three remaining wharves provide 1,292 linear feet of berthing space but are not operated from the waterside. However, the 39,885 square feet of transit sheds are occupied for storage purposes. These facilities provide a total of 4,739 linear feet of berthing space, with 79,885 square feet of transit sheds, of which 40,000 square feet are available for receipt and shipment of general cargo. All the preceding is for shallow-draft navigation. All the main wharves at Sacramento have rail connections. Municipal-belt-railroad tracks serve the shedded wharves from the rear. Ten public warehouses, located within a radius of 31/2 miles from the waterfront, provide 305,000 square feet of space for dry cargo and approximately 3,074,000 cubic feet of space for the cold storage of perishable foods. The amount of storage space at Sacramento varies according to the season of the year owing to the great amounts of rice, fruits, vegetables, and other commodi- ties that are produced in the Sacramento Valley. Thirteen of the waterfront facilities are served by one or more of the four carriers operating in the port area. Two of the carriers are trunkline railroads and two are interurban lines operated for freight service; all traverse the rich agricultural areas and provide connections with other transcontinental and local carriers. All waterborne movements to and from the port are transported by shallow-draft river steamers, tank barges, and freight barges, and will continue to be handled thusly until such time as the authorized deepwater ship channel is completed. Two grain elevators are located at the port. One, handling rice exclusively, is located on the river at West Sacramento, and is served by two wharves. The elevator, a warehouse, and storage bins have a combined capacity of approximately 1 million 100- pound sacks of rice. Additional facilities are located near Lake Washington, on the site of the new port development to be built upon completion of the deep water channel. The port district grain elevator has a capacity of 500,000 bushels of barley, wheat, or other grains in its 12 concrete silos. Additional storage capacity amounting to 375,000 bushels is currently under construc- tion by the Port District. Construction of a rice dryer, mill, and elevator, designed for direct conveyor-belt connection with sea- going vessels, has been completed by the Farmers' Rice Growers Corporation. The new plant has a capacity of more than four hundred thousand 100-pound bags of rice and there are 40 storage bins. Two warehouses have also been constructed in this area. These facilities are all serviced by rail and highway facilities. Between Sacramento and Chico Landing there are 47 ware- houses and numerous small landings. Several oil companies have recently made major capital investments for the storage of petro- leum products in the vicinity of Colusa. Freight is also handled on the bank. On the river channels, between Sacramento and the mouth of the river, there are, in addition to 1,440 linear feet of wharf with warehouse facilities at Rio Vista, 19 large wharves, RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1555 about 38 large warehouses, and many small warehouses and land- ings all owned and operated by private interests. The facilities below Sacramento, except at Rio Vista, are for shallow-draft navigation. They are considered adequate for existing commerce. The total tonnage along the project channels, including the Port of Sacramento, in calendar year 1955 was 2,228,431 tons. Operations and results during fiscal year. New work: There were no new work operations on the shallow-draft portion of the project. New work activities for the deep-draft channel to Sacramento included office engineering and design studies, preparation of a design memo for review of project benefits, and preparation of construction plans and specifications, all of which were accom- plished by hired labor. Channel enlargement, west channel of Yolo Bypass, Liberty Cut, and Prospect Slough, initiated by con- tinuing contract in fiscal year 1956, was continued; 97 percent of the work was accomplished during the fiscal year. In addition, $200,000 was expended to complete repayment of funds advanced in fiscal year 1950 by the Sacramento-Yolo Port District. Total costs during the fiscal year for new work on the deep-draft channel were $2,237,269 of which $2,437,269 was from Federal funds and minus $200,000 from funds advanced by the Sacramento-Yolo Port District. In addition, construction and minor engineering was accom- plished for the Sacramento-Yolo Port District at its expense in connection with acquisition of rights-of-way and utility alterations at a cost of $4,756. Maintenance: Deep-draft channel-None. Shallow-draft channel-Regular funds: Preliminary surveys, preparation of plans and specifications, condition surveys of the channel at various locations, minor snagging at isolated locations, miscellaneous minor spoil-area maintenance, and miscellaneous inspections and reports were accomplished by hired labor during the fiscal year. In addition, maintenance operations were per- formed as follows: a, Dredging mouth of American River and Sacramento River from "Y" Street Bend to Bryte Bend, Sacramento and Yolo Counties, by suction dredge under continuing contract, resulted in the removal of 313,067 cubic yards of material. b. Dredging of shoals in Steamboat Slough and in Sacramento River below Sacramento and from Sacramento to Colusa, by hired labor and rented clamshell dredge, resulted in the removal of 201,255 cubic yards of material. c. Removal of snags from Sacramento River, between Sacra- mento and Colusa, was accomplished by hired labor and rented equipment. d. Removal of shoals, Sacramento River, between Sacramento and Colusa, was accomplished by hired labor and rented equipment. Shallow-draft channel-deferred maintenance funds: Snags were removed from the Sacramento River between Sacramento and Colusa, by hired labor and rented equipment. 1556 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 19567 Total costs for maintenance during the fiscal year were $383,200 from Federal funds, of which $313,506 was from regular funds and $69,694 from deferred maintenance funds.

Construction of the 7-foot shal- low-draft below Sacramento was initiated in September 1899 and completed in 1904. The modified 10-foot shallow-draft up to Sacramento was initiated in fiscal year 1928 and completed in 1931. The shallow-draft channel above Sacramento was initiated in April 1946. New work on the shallow-draft channel is about 60 percent complete. The work remaining to complete the shal- low-draft portion of the project is the provision of a 5-foot depth between Colusa and Chico Landing (50 miles), subject results to be obtained by removal of snags, construction of wing dams, concentration of the channel by temporary works, and streamflow regulation of 5,000 second-feet by operation of Shasta Reservoir. Construction of the 30-foot deepwater ship channel, under the modification authorized by the River and Harbor Act approved July 24, 1946, was initiated in July 1949, and is about 12 percent complete. Construction of road, railroad, and levee embankments in the harbor area was completed by contracts in October 1949, and February 1950. Excavation of the ship channel together with necessary levee reconstruction, mile 14.1 to mile 17.8, by con- tract, was completed in October 1951. Further new construction was suspended in accordance with Presidential directive dated July 21, 1950, until fiscal year 1956. Channel enlargement, west channel Yolo Bypass, Liberty Cut, and Prospect Slough, was initiated in April 1956, by continuing contract; 99 percent of the work has been accomplished. Work remaining to complete the deep-draft portion of the project is construction of the lock with gates and operating equipment, barge canal, bascule bridge, bank protection and levees, channel and turning basin, and pumping plants and drainage facilities. The entire project as modified is about 13 percent complete. Recreational use of the Sacramento River and adjacent water- ways involves several thousand small craft and, although no record is available as to the number of persons or small craft using the waterway, it is considered to be substantial. The controlling low-water season depths were as follows: From the mouth of the river to Cache Slough, 20 feet; mouth of Cache RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1557 Slough to Sacramento, 10 feet; thence to Colusa, 6 feet in low water season; thence to Sidds Landing, 3 feet; and thence to Red Bluff, head of navigation, 1.5 feet. The channel is navigable during the entire year; however, there is no regular navigation above Sidds Landing, 178 miles above the mouth of the river.

S. ARMY, 1957 wave wash due to construction of the ship channel; however, the erosion continued and extension of the bank-protection work on the Egbert Tract levee was accomplished in 1955. The floods of December 1955-January 1956 caused failure of the bankhead on four wing dams along the shallow-draft channel above Sacramento. Failure of the bankhead causes erosion to the adjacent bank and loss of the structure and/or affects the safety of the adjacent flood control levee. Due to the extensive dredging required in fiscal year 1957 resulting from these floods, no funds have been available to perform the repairs. These wing dams will require repair in the near future. Annual maintenance dredging is required in both sections of the shallow-draft channel to remove accumulated shoals caused by settlement of floodborne sand and silt to provide the project depths in satisfactory condition to accomodate navigation require- ments. The shallow-draft channel provides a satisfactory naviga- tion channel that accommodates the using traffic throughout most of the year. Any less dredging would be unsatisfactory. The re- quired annual dredging has become of increased importance be- cause in recent years the trend has been toward increased tonnage and larger vessels.

SUISUN CHANNEL, CALIF. Location. Suisun Channel is the project channel in Suisun Slough, a tidal inlet with its mouth on the northwest side of Suisun Bay, about 7 miles northeast of Benicia and 36 miles northeast of San Francisco. The head of navigation is at the RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1559 city of Suisun, about 13 miles north of the mouth. (See U. S. Coast and Geodetic Survey Chart No. 5534.). Existing project. This provides for dredging a channel 8 feet deep at mean lower low water from Suisun Bay to and in the basin at the city of Suisun, about 13 miles in length, straightened by four cutoffs in the upper portion; channel widths to be 200 feet in the bar channel, 100 feet in the cutoffs, and a minimum of 125 feet in the remaining parts of the project channel; widening four bends located 5, 51/, 71/2, and 121/2 miles below Suisun; the removal of ledge rock from the channel at a location about 31/2 miles below Suisun; and a 1,400 by 150-foot harbor at Suisun, with an extension for a turning basin 275 feet wide and 600 feet long. The range between mean lower low water and mean higher high water is about 5 feet during the low water season, with an extreme range of 10 feet. The total Federal cost of new work for the project, completed in 1947, was $217,677. The average annual, maintenance cost during the past 5 years was $13,905. The existing project was authorized by the following: Acts Work authorized Documents June 25, 1910 To secure a channel up to Suisun, 6 feet deep at low H.

Local cooperation. Local interests are required to furnish free of cost to the United States all necessary rights-of-way and suit- able spoil-disposal areas for new work and subsequent mainte- nance, undertake any necessary reconstruction of the powerline crossing over the proposed cutoff near Suisun, and provide at Suisun adequate public terminal facilities subject to the approval of the Chief of Engineers. These requirements have been fulfilled except for the public terminals, which will be completed when materials are available at reasonable cost. Terminal facilities. There are three wharves in the city of Suisun, with a total of 600 feet of berthing space. There is also warehouse space of 33,500 square feet, and ari oil storage terminal. These are all privately owned and operated and will be increased in compliance with the provisions of local cooperation, as land has been purchased, financing arranged, and plans have been prepared for construction when materials are available at reasonable cost. Certain facilities are in use for military purposes. The total tonnage through the channel in calendar year 1955 was 159,067 tons. 1560 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 Operationsand results during fiscal year. Maintenance: Opera- tions during the year consisted of condition surveys of the channel and preparation of spoil area, all of which was accomplished by hired labor. Total costs during the fiscal year were $2,593 for maintenance. Condition at end of fiscal year. The construction of new work was initiated in March 1912; improvement of the channel modification authorized in 1937 was initiated in May 1946, and completed in June 1947. The channel is navigable during the entire year; head of navigation is in the city of Suisun, Calif., about 400 feet above Sacramento Street. The controlling depth is 7 feet in the channel and harbor basin at mean lower low water. The periodic maintenance performed on this waterway provides a satisfactory navigation channel that accommodates general navi- gation and defense transportation requirements. Maintenance dredging is required to remove accumulated shoals to assure adequate project depths, to accommodate general navigation and defense transportation requirements. The Delta Region of the Sacramento-San Joaquin River Sys- tems, together with Suisun Bay and associated waterways, is within reach of the large population in and about the San Fran- cisco Bay Area. Recreational use of these waterways involves several thousand small craft. No record has been maintained of persons or small craft using Suisun Channel; however, it is con- sidered to be substantial. Total costs for the project to June 30, 1957, were $354,920, of which $217,677 was for new work and $137,243 for maintenance.

SUISUN BAY CHANNEL, CALIF. Location. Suisun Bay is about 30 miles northeast of San Francisco, Calif., and is an integral part of the waterways which provide access to the Pacific Ocean from inland ports of Califor- nia. Sacramento and San Joaquin Rivers flow to a junction and empty into Suisun Bay near Collinsville, and New York Slough, a distributary of San Joaquin River, leads to the head of Suisun Bay at Pittsburg, Calif. The port of Sacramento is situated on the Sacramento River about 60 miles north of Collinsville; the city of Stockton is on the San Joaquin River about 40 miles above Pittsburg and access to the city has been provided by Stockton Deepwater Channel. (See U. S. Coast and Geodetic Survey Chart No. 5534.) RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1561 Previous project. The River and Harbor Act of March 2, 1919, provided for a channel 300 feet wide from Martinez to Antioch, Calif., 24 feet deep across the lower shoal near Bulls Head Point, 20 feet deep across Point Edith and Middle Ground Shoals, and 18 feet deep through New York Slough; all depths refer to mean lower low water. Local interests were required to contribute toward the first cost of construction and to provide spoil area together with the required impounding levees. For further de- tails, see page 1756 of Annual Report for 1920, page 1562 of Annual Report for 1926, and page 1714 of Annual Report for 1938. Existing project. This provides for a channel 300 feet wide and 30 feet deep through Bulls Head Point, Point Edith, and Middle Ground Shoals to the mouth of New York Slough, a dis- tance of about 13 miles, and for a channel 250 feet wide and 20 feet deep south of Seal Island from the main channel at Point Edith, mile 3, to the main channel again at Bay Point, mile 6. All depths refer to mean lower low water. The tidal range between mean lower low water and mean higher high water is about 6 feet. The extreme range is about 9.5 feet. The total Federal cost of new work for the existing project, completed in 1934, exclusive of work accomplished under the public works program as part of the San Joaquin River 30-foot project, was $142,026. The average annual maintenance cost during the past 5 years was $60,350. The existing project was authorized by the following: Acts Work authorized Documents 1 Jan. 21, 1927 __-------- ..

Local cooperation. Fully complied with. Terminal facilities. Along the channel between the western end of the bay and mouth of New York Slough, there are three wharves and two car-ferry slips, all privately owned and used. Also, a naval magazine with wharves and warehouses has been constructed at Port Chicago, on the southern shore (mile 6). These facilities are considered adequate for existing commerce. The total tonnage through the channel in calendar year 1955 was 3,925,056 tons. Operationsand results during fiscal year. Maintenance: Opera- tions during the year accomplished by hired labor included pre- liminary surveys, preparation of plans and specifications, mis- cellaneous inspections and reports, and condition surveys. The Government owned hopper dredge Pacific was utilized to remove 160,958 cubic yards of material in maintenance dredging at scattered locations in Suisun Bay Channel. Total costs for maintenance during the fiscal year were $55,780. 1562 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Condition at end of fiscal year. New work under the existing project was initiated in June 1930, and completed in 1934; a por- tion of this work was accomplished under the public works program. The portion of the existing project authorized prior to the public works program was completed in 1931 except for deepening the 26-foot channel across Bulls Head Point to 30 feet; this portion was subsequently included in the public works pro- gram. Work under the public work program was accomplished during 1933 and 1934. The channel is navigable during the entire year and provides access to San Francisco Bay from the naviga- tion channels of San Joaquin and Sacramento Rivers. The Delta Region of the Sacramento-San Joaquin Rivers together with Sui- sun Bay and associated waterways is within reach of the large population of the San Francisco Bay Area. Although no record is available of the numbers of craft or persons participating, recre- ational use is considered substantial. The controlling depth at mean lower low water in the main channel is 30 feet, and in the channel south of Seal Island is 14 feet. The project has been maintained in a condition to satisfy general and defense navigation requirements. Annual dredging is required to maintain the project depth and width in a satisfactory manner without undue interference to essential general and defense navigation require- ments. Total costs for the existing project to June 30, 1957, exclusive of the work performed under the public works program at a cost of $207,198 as a part of the San Joaquin River 30-foot project, were $1,195,667, of which $142,026 was for new work and $1,053,641 for maintenance.

OLD RIVER, CALIF. Location. Old River is the most westerly branch of the inter- connecting tidal channels into which San Joaquin River divides in crossing its delta. It leaves the main river 21/2 miles down- stream from the Mossdale State Highway Bridge, or 13/ miles above the mouth of Stockton Channel, and flows westerly and northerly 32 miles to its lower confluence with the main river 23 miles above its mouth in Suisun Bay. RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1563 Existing project. This project extends along Old River from its mouth near Venice Island to its source in the San Joaquin River near Mossdale and provides for a side channel 10 feet deep and 80 feet wide to Santa Fe wharves and Phillips cannery at Orwood; for channels 10 feet deep and 100 feet wide in Grant Line Canal west of Doughty Cut, 10 feet deep and 80 feet wide from the westerly end of Doughty Cut to the Holly Sugar factory, 2 miles north of Tracy, 8 feet deep and 80 feet wide from the southerly end of Doughty Cut to head of Old River, and 6 feet deep and 80 feet wide in Old River from the westerly end of Grant Line Canal to Lammers Ferry Road; and for entrances 8 feet deep and 80 feet wide to Fabian-Bell Canal at its westerly end and also westerly of Grant Line Bridge. All depths are referred to mean lower low water. The tidal range between mean lower low water and mean higher high water at the head of Old River is about 3 feet; and at its mouth about 5.5 feet; ordinary flood ranges are, respectively, 16 feet and 8 feet; extreme flood ranges are, respectively, 20 feet and 11 feet. The Federal cost of new work for the completed portion was $23,185. The average annual maintenance cost during the past 5 years was $14,415. The uncompleted portion of the project, consisting of comple- tion of the project channels at Orwood, from Crocker Cut to the head of Old River, and in the original channel of Old River from Grant Line Canal up to Lammers Ferry Road, is considered to be inactive and has been excluded from the foregoing cost estimate. The cost of this portion was last revised in July 1954, and was estimated to be $62,815. The existing project was adopted by the River and Harbor Act of August 26, 1937 (H. Doc. 151, 75th Cong., 1st sess.). This document contains the latest published map. Local cooperation. Local interests are required to furnish without cost to the United States all necessary rights-of-way and suitable spoil-disposal areas for new work and for subsequent maintenance as necessary, and to agree to provide public landings satisfactory to the Chief of Engineers on each side of the proposed channel in the Old River near Lammers Ferry Road and on the Fabian-Bell Canal west of Grant Line Bridge. Spoil-disposal areas have been provided for those channels so far completed. Terminal facilities. The Santa Fe Railroad has a warehouse and wharf at Orwood for transfer of farm produce from boat to rail. The Phillips cannery at Orwood has similar facilities. The Holly Sugar Co. refinery and terminal near Tracy has a large wharf and an unloading basin with three mechanical unloading and conveying units connecting with a warehouse; there is also a passing basin one-half mile downstream. There are about 100 private bank landings along the project channels; some have sheds for storage. These are all privately owned and operated. Public landings should be provided as set forth above under "Local cooneration." The total tonnage through the channels of the project in calendar yer,1955 was 202,627 tons. : 1564 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Operation and results during fiscal year. Maintenance. Opera- tions during the year consisted of miscellaneous inspections and reports, including maintenance of gages and gage reading by hired labor. In addition, dredging operations, by contract clamshell dredge, were also performed in Crocker and Paradise Cuts near Old River, resulting in the removal of 26,875 cubic yards of material. Total costs during the fiscal year were $9,121 for maintenance. Condition at end of fiscal year. New work was accomplished in fiscal year 1939 in Old River Channel from its head in San Joaquin River to Grant Line Canal and in the channels of Grant Line Canal, Crocker Cut, and Doughty Cut. Existing commerce does not indicate a need for completion of the remaining channel con- struction. The channel is navigable during the entire year and provides the only avenue of water transportation from the delta islands to certain agricultural processing plants. The project has been maintained in a condition to satisfy general navigation re- quirements. It is necessary to perform annual maintenance dredg- ing to maintain full channel dimensions in order to accommodate the using traffic. Approximately 200,000 cubic yards of shoals were caused by floodborne sand and silt along Grant Line Canal and in channels leading to Holly Sugar Factory as a result of the floods of December 1955-January 1956. The two heads of naviga- tion are at the head of Old River in San Joaquin River, and at the Holly Sugar Factory wharf, 2 miles north of Tracy. The con- trolling depths at the end of the fiscal year were: From the mouth of the river to Orwood, 11 miles, 10 feet; thence to the lower end of Grant Line Canal, 10 miles, 10 feet; thence (1) to Holly Sugar Factory near Tracy, 5 feet (low water season), or (2) to head of Old River in San Joaquin River, 5 feet (low water season). All depths refer to mean lower low water. There is a minor amount of recreational traffic that uses this channel and interconnecting sloughs. Total costs for the project to June 30, 1957, were $321,973, of which $23,185 was for new work and $298,788 for maintenance.

SAN JOAQUIN RIVER, CALIF. Location. San Joaquin River rises in east Central California in the Sierra Nevada about 25 miles southeast of the Yosemite RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1565 Valley and flows southwesterly to the town of Mendota, thence northerly to its confluence with Sacramento River about 48 miles northeast of San Francisco to empty into Suisun Bay near Collins- ville, Calif. Total length of the river is about 340 miles. Near the mouth, a distributary channel, New York Slough, 3 miles long, leads to the head of Suisun Bay at Pittsburg; thence a deep chan- nel extends through this bay and others to San Francisco. The city of Stockton is on the east side of San Joaquin River about 40 miles above Pittsburg and access to the city has been provided by Stockton Channel, an artificial cut extending from the river about 21/4 miles into the city. (See U. S. Coast and Geodetic Survey Sheet No. 5527.) Existing project. The San Joaquin River project for naviga- tion was authorized in numerous River and Harbor Acts since 1876. It provides for the Stockton Deep Water Ship Channel to the city of Stockton and for minor channel improvements from Stockton Channel upstream for 86 miles to Hills Ferry to facilitate light-draft navigation. The 1927 River and Harbor Act author- ized the original deep water channel with a depth of 26 feet, which was subsequently modified to 30 feet by the 1935 authorization, and the most recent modification of the project was authorized by the 1950 River and Harbor Act. This improvement, as authorized by the River and Harbor Acts through May 17, 1950 (Public Law 516, 81st Cong.), provides for a channel 30 feet deep at mean lower low water and for channel bottom width of 400 feet below Criminal Point (near river mile 25) and 225 feet above that point, from the mouth of New York Slough to Mormon Channel at Stockton, a distance of 41 miles (suitably widened at bends and at the entrances to New York Slough and to channels through shoals, with levees set back 230 feet from the center of the channel) ; for a channel 30 feet deep and 150 feet wide thence to Weber Point, 1 mile; for a 9-foot depth, thence to the head of navigation at Eldorado Street, one- half mile; for a 9-foot depth at Fremont Channel and McLeod Lake, arms of Stockton Channel; and for a channel 9 feet deep and 100 feet wide in Mormon Channel from its mouth to Washing- ton Street, head of navigation, about 1 mile. It also provides for suitable passing basins and a turning basin 30 feet deep, 960 feet wide and 1,900 feet long at Stockton; for a turning basin 30 feet deep, 600 feet wide and 1,350 feet long adjacent to Rough and Ready Island; for a triangular shaped settling basin 30 feet deep and average side length of about 1,000 feet at the San Joaquin River just above its junction with the deep water channel (mile 42) and a second settling basin 30 feet deep, 100 feet wide and 1,200 feet long adjoining the deep water channel at the mouth of Calaveras River; for dredging an additional settling basin 17 feet deep, 600 feet wide and 2,000 feet long on San Joaquin River above the head of Burns Cutoff; for a leveed channel 30 feet deep and 225 feet wide around Rough and Ready Island including con- struction of a combination railroad and highway bridge; for the reconstruction to grade and section of about 4,000 feet of levee along the north side of Venice Island Cut, and the setting back of 1566 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 levees where required for channel improvements and placement of bank protection on the face of such levees along the San Joaquin River below Stockton as have been critically damaged by traffic- induced wave action; for cutting off sharp bends and making cut- offs in the river; for filling Mormon Channel and Mormon Slough above Washington Street with dredge spoil insofar as is eco- nomically feasible; for partial closing of side channels at Laird Slough and Paradise Cut by weirs to confine the low-water flow to one main channel; and for snagging, removing overhanging trees, and constructing brush wing dams from the mouth of Stock- ton Channel to Hills Ferry, 86 miles, to facilitate light-draft navi- gation on this part of the river during higher stages of water. The entire project is about 32 percent complete; the 1950 modification is about 7 percent complete.

The Federal cost of work authorized prior to the 1950 modification was $4,010,000. Maintenance of the channel to project depths after completion is the responsibility of the Federal Government. The average annual maintenance cost during the past 5 years was $112,820. The average cost is lower than the estimated cost due to lower than average availability of funds during these years. Operations and maintenance of the combined rail and highway bridge and any other bridges required over the waterway, main- tenance of utilities, and maintenance of existing levees and new levees is the responsibility of local interests. Local cooperation. All requirements for work accomplished to date under the authorization of the River and Harbor Acts through August 26, 1937, have been complied with. In accordance with those acts, local interests were required to furnish, free of cost to the United States, all lands, rights-of-way, and suitable spoil-disposal areas for new work and for subsequent maintenance; contribute $1,307,500 toward the first cost of the dredging for the 26-foot project; provide terminal facilities; and assume main- tenance of the levees. In accordance with the River and Harbor Act of May 17, 1950; local interests are required to (1) except for the new turning basin, furnish free of cost to the United States all necessary lands, RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1567 easements, rights-of-way, and suitable spoil-disposal areas for the new work and subsequent maintenance, when and as required; (2) agree to accept ownership of the combined rail and highway bridge upon completion of construction, together with maintenance, operation, and future replacement or alteration as may be re- quired, provide and maintain any other bridges required over the waterway, and accomplish all necessary utility relocations and alterations and the maintenance thereof; (3) contribute progres- sively as the project is constructed, at such rate as is satisfactory to the Secretary of the Army, a total of $530,000 in cash toward the cost of new work of the improvement; (4) prior to enlarge- ment of Stockton Channel and construction of the channel around Rough and Ready Island, agree to provide, maintain, and operate suitable terminal and related facilities at the site of the improve- ment under consideration; (5) agree to continue to maintain the levees along the deep water channel including those provided with bank protection by the Federal Government and those bordering the improved channel around Rough and Ready Island; and (6) agree to hold and save the United States free from damages resulting from construction, maintenance, and operation of the proposed improvements.

Local interests are represented by the Stockton Port District formed under the laws of the State of California as provided in chapter 1028 of the Statutes of 1931 for the purpose of carrying out the required local cooperation. The district furnished as- surances, dated September 21, 1954, for the 1950 authorized modification; Sacramento District accepted the agreement for the 1568 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMYS19B7: Secretary of the Army on December 14, 1954. Required lands and rights-of-way will be provided as required for prosecution of the project. Total non-Federal cost of the earlier work is not available since the total cost to local interests of compliance with local cooperation requirements is not known. It is known, how- ever, that the local interests contributed $1,307,500 toward the construction cost of that work. Total estimated costs for all re- quirements of local cooperation for the 1950 modification under terms of the project authorization, including required non-Federal contributions but exclusive of terminal facilities, amount to $1,930,000 (1957). The estimated costs include a cash contribu- tion of $530,000 and an additional outlay of $1,400,000 for lands, rights-of-way, and relocations required for project construction. Estimated costs for the additional terminal facilities are not available. Authority was granted October 12, 1954, by the Comptroller of the Army for acceptance of funds to be contributed by the port of Stockton progressively as the project is constructed. $35,000 was contributed in November 1954 toward they enlargement of the turning basin as Stockton. Terminal facilities. The harbor facilities at the port of Stock- ton, Calif., consist of 55 piers, wharves, and docks which are lo- cated along the San Joaquin River and on the Stockton, Mormon, and Fremont Channels. With the exception of four facilities on the San Joaquin River and three on Mormon Channel, all facilities are located on Stockton Channel or in proximity thereto. Nearly half of the port's water terminals are bulkhead-type shore wharves with sufficient depths of water to accommodate ordinary river craft; the ocean terminals are concrete marginal wharves; and the remainder are generally open pile, timber-decked piers, shore wharves, or offshore wharves. General cargo facilities (six in number) and petroleum handling facilities (seven in number), are indicative of the foremost items of waterborne commerce handled at the port. The harbor facilities include a marine service sta- tion, facilities for handling creosote, treated piling, fruits, vege- tables, ore and other bulk materials. About one-half of the waterfront facilities are owned by the city of Stockton and are under the jurisdiction of the Stockton Port District governed by the board of port commissioners. The Stockton Port District is the agency operating the Stockton ocean terminal, comprised of seven public wharves and a bulk-material wharf providing 3,335 feet of berthing space in depths of 28 and 29 feet, mean lower low water, with approximately 303,400 square feet of transit sheds, as well as 508 feet of open wharf. Eight oceangoing vessels can be accommodated at one time at the public ocean terminal. The transit sheds are provided with rail connec- tions by the Stockton public belt railroad. The port also owns and operates five storage warehouses with a total of 799,420 square feet of storage area available for public merchandise, equipped with portable mechanized handling equipment and served by trackage of the belt railroad, adjacent to the public ocean termi- nal which includes a cotton warehouse and compress with 246,400 RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1569 square feet of floor area and a grain terminal. The grain termi- nal has a flood area of 185,140 square feet and a cubical capacity of 3,414,600 feet. Approximately 1,000,000 square feet open-stor- age space is available at Stockton Port District public wharves for' commodities not affected by weather conditions. The open- storage space is readily accessible to trucks and is served by trackage of the belt railroad. Portable handling equipment and a 12 1/2 -ton locomotive crane serve the storage areas on the port district property. Certain facilities at the Stockton port terminal are in use for military purposes. A naval supply depot (Stockton Annex) has been completed on Rough and Ready Island, bounded by the Stockton Deepwater Channel on the north side, San Joaquin River on the east side, and Burns Cutoff on the south and west sides. Shallow-draft facilities on the upper channel include 12,500 linear feet of wharves of which 8,620 linear feet are privately operated, the remainder being operated by the Stockton Port District. Included along these wharves are 341,600 square feet of -transit sheds and 225,370 square feet of storage warehouses. There are two privately owned cold-storage warehouses located on Mormon Channel with a total storage capacity of 1,582,750 cubic feet, of which 1,124,750 cubic feet are available for public storage. The port owns and operates the belt-line railroad, which con- nects with three transcontinental railroads and serves all facilities in the area; highway trucks are afforded easy access by paved streets and roads. An excellent system of improved highways connects the port with the Pacific coastal areas, as well as the surrounding agricultural area. Downstream from Stockton, the traffic is accommodated by bank landings and sheds, except at Antioch and near Pittsburg, where there are wharves for shallow- and deep-draft vessels. The terminal transfer facilities at the public ocean terminal of the port of Stockton are adequate for the present and immediate future. There has been a sustained annual growth of traffic in and out of the port of Stockton. The turning basin enlargement, accomplished in 1955, facilitates the use of the loading and storage facilities added by the port of Stockton during recent years to accoinmodate the greatly increased tonnage handled by the port. The port has expanded its loading and storage facilities to handle iron ore brought in by rail from Nevada: it is expected that this item 'will reach 1,000,000 tons a year. It is expected that con- struction of the remaining facilities authorized by the 1950 River and Harbor-Flood Control Act will be required in the relatively near future to accommodate the additional requirements of indus- try and commerce. The total tonnage along the project channels, including the port of Stockton, in calendar year 1955 was 2,413,938 tons. Of this amount, over 1,000,000 tons was deep-draft cargo and the balance barge traffic. Operations and results during fiscal year. New work: En- gineering, including surveying and mapping, design office studies, 1570 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 and preparation of contract plans and specifications, was continued during the fiscal year by hired labor. Stone protection along Stockton Deep Water Channel, San Joaquin County, was accom- plished by contract. In addition, levee repairs and stone protec- tion along Stockton Deep Water Channel, San Joaquin and Contra Costa Counties, was accomplished by contract. Maintenance: Dredging operations, by contract suction dredge, resulted in the removal of 176,650 cubic yards of materials in Stockton Deep Water Channel at junction of San Joaquin River and Stockton Channel, San Joaquin County. Dredging opera- tions, by Government hopper dredge Pacific, were also performed along San Joaquin River from Calaveras River to New York Slough, resulting in the removal of 4,000 cubic yards of material. Hopper dredge surveys, New York Slough to Antioch Bridge, were performed by hired labor and rented equipment. Operations dur- ing the year also included condition surveys of the channel at various locations, maintenance of gages and gage readings, prep- aration of plans and specifications, and miscellaneous field re- connaissance and reports, all of which were performed by hired labor. Total costs during the fiscal year were $570,980 from Federal funds of which $434,400 was for new work and $136,580 for maintenance. Condition at end of fiscal year. The existing project is about 32 percent complete. Construction of the project was initiated in December 1877; further modifications were subsequently author- ized and accomplished. The 9-foot channel up to Stockton, author- ized in 1910, was initiated in 1915 and completed in 1923. Im- provement of Fremont Channel and McLeod Lake, authorized in 1912, was accomplished in 1914. Dredging of the 26-foot chan- nel up to Stockton, authorized in 1927, was initiated in 1930 and completed in 1933. The original 30-foot channel up to Stockton, which was included in the public works program under the Na- tional Industrial Recovery Act and subsequently authorized in 1935, was accomplished during 1934 and 1935. Dredging of the widened 30-foot channel, authorized in 1937, was initiated in 1938 and completed in October 1940;- Mormon Channel was dredged from the junction with Stockton Deep Water Channel to a point near Washington Street Bridge at Stockton in 1948. All work authorized prior to May 1950 is complete except for the dredging above the south line of Main Street in Stockton to a depth of 9 feet; local interests have advised that dredging above the south line of Main Street will not be required. Enlargement of the existing turning basin, authorized in 1950, was accom- plished in 1955. Levee repairs and bank protection were initiated in fiscal year 1957. The 1950 modification is about 7 percent com- plete. The turning basin in Stockton Channel is 960 feet wide and has a length of 1,900 feet along the northerly edge, tapering to 1,100 feet along the southertly edge. The Delta Region of the Sacramento-San Joaquin River is ideal for fishing and aquatic sports and is within reach of the large population in and about the San Francisco Bay Area. Although RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 1571 no attempt has been made to determine the numbers of craft or persons participating, recreational use in considered substantial. The controlling depth from mouth of the river in Suisun Bay to Mormon Channel, 41 miles, is 30 feet; thence to Edison Street, three-quarters of a mile, 22 feet; and thence to head of navigation at Center Street, one-half mile, 9 feet. A 9-foot depth is available in Mormon Channel, up to Main Street, 0.9 mile; thence 2 feet to Center Street, head of navigation; and 9 feet in Fremont Channel and McLeod Lake. All depths are referred to mean lower low water. The channel is navigable during the entire year. The river, from its junction with Stockton Channel to the Moss- dale Bridge (16 miles), usually has a controlling depth of 3 feet from April to June, inclusive, and from Mossdale Bridge to Hills Ferry (70 miles), head of navigation, the usual controlling depth is 3 feet from April to June, inclusive. Navigation in the section above the San Joaquin Bridge (Southern Pacific Railroad cross- ing), at Mossdale, is impracticable in the low stages after June. New work remaining to complete the project consists of the con- struction authorized by the River and Harbor Flood Control Act of May 17, 1950, except for enlargement of the existing turning basin, including completion of levee construction and bank pro- tection, for modification of the navigation project.

SACRAMENTO RIVER AND TRIBUTARIES, CALIF., FROM COLLINSVILLE TO SHASTA DAM Location. The Sacramento River rises in the Trinity Moun- tains in north-central California, flows in a general southerly direction about 374 miles and empties into Suisun Bay, an arm of San Francisco Bay at Collinsville, Calif. The works covered by this improvement are on the Sacramento River and tributaries from Collinsville to Shasta Dam, about mile 312. The drainage FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1573 area above Rio Vista is 26,500 square miles. (See U. S. Geologi- cal Survey quadrangles of the area for Sacramento River and upper Butte Basin; Flournoy and Fruto quadrangles for Black Butte Reservoir; and the Tuscan Buttes, Tehama, Redding, and Hooker quadrangles for Table Mountain Reservoir). Existing project. The improvement of Sacramento River and tributaries, from Collinsville to Shasta Dam, was authorized as a unit of comprehensive plan for flood control and other related purposes in the Sacramento River Basin. The active elements of the project comprise the enlargement of existing levees on Sacra- mento River between vicinity of Moulton weir and Ord Bend; the construction of new levees from the present levee terminus to vicinity of Chico Landing; construction of Chico Landing weir; the extension of the existing Moulton weir; and the enlargement of existing levees in Sutter, Tisdale, and Sacramento Bypasses and a portion of Yolo Bypass. In addition to the above, the project includes levee construction and/or channel enlargement on the following minor tributaries of the Sacramento River below Red Bluff: Antelope Creek; Chico and Mud Creeks, and Sandy Gulch; Butte and Little Chico Creeks; Cherokee Canal; Elder Creek; Deer Creek (Tehama County) ; Thomes Creek, and Willow Creek. These improvements are for the purpose of flood control. The improvement provides for approximately 265 miles of channel improvement and about 335 miles of levees with an average height of 12 feet. A freeboard of 3 feet will be provided by the river levees and 5 to 6 feet by the bypass levees. Construction of the levee and channel improvements was initiated in May 1949 and is about 10 percent complete. The above levee construction supplements the program of levee improvements which are being accomplished pursuant to the Flood Control Act of March 1, 1917, as amended by subsequent acts, including the Flood Control Act of August 18, 1941, and which are reported by California Debris Commission under im- provement No. 4 "Sacramento River, Calif., Flood Control." The project is an integral part of the overall plan for flood control and other purposes in the Sacramento River Basin. It is designed either to supplement certain of the proposed reservoirs by directing or confining the regulated flood flows to nondamaging channel sections or stages, or to reduce or alleviate the local flood hazard along streams on which no impoundment is planned at this time. The areas affected by the active portion of the project include the towns of Chico, Willows, and smaller communities, and about 112,000 acres of agricultural lands. In addition, limited protection will be provided to Upper Butte Basin. In conjunction with authorized reservoirs, the project will provide flood protec- tion to some areas along the main river and to Highway Nos. 99E and 99W, to the main lines of the Southern Pacific Railroad, to other State and county highways, and feeder railroads. The authorization also provides for the construction of the Black Butte Reservoir, an earthfill dam, with a maximum height of 127 feet, to create a reservoir with a gross storage capacity of 160,000 acre-feet for flood control and water conservation pur- 1574 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 poses. The improvement will be located in Tehama and Glenn Counties about 9 miles westerly of Orland, Calif., on Stony Creek, a tributary entering the Sacramento River at mile 190. The reservoir will provide flood protection from flooding by Stony Creek to the towns of Orland and Hamilton City, to a transconti- nental highway, to a transcontinental railroad, to important food processing plants, and to about 35,000 acres of agricultural land lying along the lower reaches of Stony Creek and west of Sacra- mento River and, in addition, will provide about 60,000 acre-feet of new water annually for irrigation. This project, in conjunc- tion with the levee and channel improvements of the comprehensive plan, will help reduce flooding along the Sacramento River and in Butte Basin. The latest approved estimate of Federal cost for new work (1957) of the principal features is as follows: Estimated cost Project Lands and dam- Construction ages (including Total relocation) Levees, Sacramento River and tributaries 2.. $22,000,000 ..-.-.. --..- $22, 000,000 Black Butte Reservoir...................... 17, 338, 000 $962,000 18, 300, 000 Total_- ....-----. . --. --.-..... -.- 39, 338, 000 962, 000 40, 300, 000 1 Active units of Sacramento and tributaries. The construction of the necessary works for improvements of Upper Butte Basin, authorized by the 1950 Flood Control Act, exclusive of the work applicable to the extension of Moulton weir which has been retained in the active portion, has been deferred for restudy and is excluded from the foregoing cost estimate. The cost of this unit was last revised in July 1954 and was esti- mated to be $3,530,000 for construction. Levee construction in Lower Butte Basin and in Lower Yolo Bypass, exclusive of work applicable to the extension of Moulton weir which has been retained in the active portion, are considered to be inactive and are also excluded from the foregoing cost esti- mate. The costs of these units were last revised in July 1954 and were estimated to be $7,286,500 for Lower Butte Basin and $3,733,500 for Lower Yolo Bypass for construction. In addition, Table Mountain (Iron Canyon) Reservoir is also considered to be inactive and is excluded from the foregoing cost estimate. The cost of this project unit, including the power facility, was last revised in July 1954 and was estimated to be $77,200,000, of which $4,417,900 was for lands and damages including relocations and $72,782,100 for construction. Operation and maintenance of the levee and channel improve- ments after completion will be the responsibility of local interests. Operation and maintenance of the Black Butte Reservoir will be the responsibility of the Federal Government. Local interests will reimburse the United States for conservation accomplishments of the reservoir. FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1575 The improvement was adopted by the Flood Control Act of December 22, 1944 (H. Doc. 649, 78th Cong., 2d sess., which con- tains the latest published map), which authorized to be appro- priated for the initiation of the project the sum of $15,000,000; further amendment by the Flood Control Act of May 17, 1950 (H. Doc. 367, 81st Cong., 1st sess.), included construction and monetary authorization for the necessary works of improvement for the protection of the Upper Butte Basin, currently deferred for restudy. Local cooperation. Levee and channel improvements, Sacra- mento River and tributaries: Local interests are required to pro- vide all lands, easements, and rights-of-way necessary for the project; bear the expense of all necessary utility changes and modifications; hold and save the United States free from claims for damages resulting from construction; and maintain and operate at their own expense all flood control works after com- pletion in accordance with regulations prescribed by the Secretary of the Army. The State of California officially adopted the project by chapter 1514 of the Statutes of 1945 and instructed the Reclamation Board of the State of California to carry out the required local coopera- tion. By letter dated March 4, 1945, the Reclamation Board furnished the Sacramento District an opinion by the State At- torney General that the assurances furnished by the State by chapter 656 of the Statutes of 1939, State of California, for the Sacramento River Flood Control project were sufficient to cover this project. On March 22, 1948, the Chief of Engineers accepted this opinion as satisfactory for the required assurances. The Reclamation Board has furnished all rights-of-way required to date and has indicated that it will furnish all rights-of-way required as needed for future construction. Units of the project are transferred to the State of California for maintenance and operation as they are completed. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non- Federal contributions, amount to $3,500,000 (July 1957) for the active units of the levee and channel improvements. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non- Federal contributions, amount to $1,787,000 (1954) for the Upper Butte Basin improvements, which is currently deferred for restudy. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non- Federal contributions, amount to $2,285,000 (1954) for Lower Butte Basin and $222,000 (1954) for Lower Yolo Bypass. These units are considered to be inactive. Black Butte Dam and Reservoir: Local interests are required to make payment to the United States for the conservation features of the project, but no local cooperation is required for construction of the dam and reservoir. Chapter 1514 of the Statutes of 1945, State of California, officially adopted the project. Only informal 1576 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 general assurances have been furnished by local interests that they would meet the requirement. At a public meeting on November 29, 1955, local water users expressed the opinion that there would be little difficulty in contracting for conservation storage in the reservoir. Operations and results during fiscal year. a. Construction and enlargement of levees and, local improvements on Sacramento River and major and minor tributaries (active portions): En- gineering and design, including surveying and mapping and preparation of contract plans and specifications, was continued by hired labor during the year. Additional field surveys were ac- complished, utilizing contract engineering survey services. In addition, levee construction along the left bank of Deer Creek, at Delaney Slough, Tehama County, was accomplished by contract. Total cost of new work for the levee and channel improvements during the fiscal year was $161,794, of which $158,459 was from Federal funds and $3,335 from contributed nonproject funds. b. Black Butte Reservoir: Engineering and design, including field surveys and investigations, preparation of design memor- anda, and preliminary cost allocation studies, was accomplished by hired labor during the year. In addition, field surveys and investigations were accomplished by contract and/or hired labor and rented equipment. Total cost of new work for Black Butte Reservoir during the fiscal year was $209,308. c. Table Mountain (Iron Canyon) Reservoir: This improve- ment is considered to be inactive and there was no operation nor cost during the fiscal year.

Construction and enlarge- ment of levees and channel improvements on Sacramento River and minor tributaries (active portions) : Construction of the project was initiated in May 1949; items completed include the Deer Creek levees and a portion of the Butte Creek Channel improvements and levees. Further construction was suspended as a result of the Presidential directive dated July 21, 1950, due to the Korean emergency. Construction was resumed on this improvement in fiscal year 1957. Engineering, including field surveys, and preparation of detailed plans and contract plans and specifications, is being continued. The active portion of this improvement is about 10 percent complete. FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1577 Levee work remaining to be done for the active portions of the project includes enlargement of existing levees on Sacramento River between the vicinity of Moulton weir and Ord Bend; the construction of new levees from the present levee terminus to the vicinity of Chico Landing; construction of Chico Landing weir; the extension of the existing Moulton weir; and the enlargement of existing levees in Sutter, Tisdale, and Sacramento Bypasses and a portion of Yolo Bypass. In addition to the above, the project includes uncompleted levee construction and channel enlargement on the following minor tributaries of the Sacramento River; Antelope Creek; Chico and Mud Creeks, and Sandy Gulch; com- pletion of Butte and Little Chico Creeks; Cherokee Canal; Elder Creek; Thomes Creek; and Willow Creek. Total cost of new work to June 30, 1957, was $2,162,760, of which $2,058,531 was from Federal funds and $104,229 from contributed non-project funds. As a result of the heavy rainfall in December 1955, flood peaks on minor tributaries of Sacramento River (Cherokee Canal and Butte, Little Chico, Chico, Antelope, Elder, Thomes, and Willow Creeks) were large, but did not exceed previous record flows, except on Thomes Creek where a peak of about 23,700 cubic feet per second on December 22, 1955, exceeded the previous record flow of about 18,600 cubic feet per second in January 1943. Per- sistent stormy weather in January and February 1956 caused some flooding in many places, but the damage had already been done by the December 1955 flooding. The Deer Creek levees, partially completed in 1949, prevented flooding along Deer Creek, although they were severely eroded and broken in some places. Areas within Sutter, Tisdale, Yolo, and Sacramento Bypasses, and part of Butte Basin were flooded, as is to be expected when the river reaches certain stages of flow. Damage prevented by the partially completed Deer Creek project and the partially completed Butte Creek project, amounted to about $300,000. Local interests levees, along the lower reaches of many of the minor streams, prevented some flooding. An additional $1,300,000 damage experienced during these floods would have been prevented had the entire project been completed and in operation, of which $250,000 would have been attributable to the Little Chico-Butte Creek unit. b. Black Butte Reservoir: Data for definite design studies have been assembled, including general design, surveying and mapping and exploration and materials tests. The design memo for the dam and appurtenances is about 40 percent complete. Engineer- ing studies were discontinued subsequent to fiscal year 1952 due to lack of funds until resumed during fiscal year 1956. Construc- tion has not been initiated. Total cost of new work to June 30, 1957 was $366,265. During the floods of December 1955, flood damages on Stony Creek were principally to roads and bridges in the mountainous headwater area, and to levees on the lower reach of the stream. The damages above Black Butte Dam site amounted to $128,000 and below Black Butte Dam site to $29,000. If the reservoir had 1578 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 been built and in operation, it would have prevented all of the damages to the levees in the lower reach of the creek. c. Table Mountain (Iron Canyon) Reservoir: This improve- ment is considered to be inactive. If this improvement had been constructed and in operation, it would have reduced the flows of the December 1955-January 1956 floods into the flood-bypass system upstream of Fremont Weir. Total cost of new work for the entire project to June 30, 1957, was as follows: Federal Contributed Project funds funds 1 Total Sacramento River and major and minor tributaries (active portions) ----------- $2, 058,531 $104,229 $2, 162,760 Black Butte Reservoir_ _ __-------------- - - 366,265 ------------------- _ 366,265 Total -------------------------------- 2,424,796 104,229 22,529,025 1Contributed nonproject funds for miscellaneous construction at the expense of local interests in connec- tion with acquisition of rights-of-way and utility alterations for Sacramento River and major and minor tributaries. 2 Exclusive of costs in the amount of $151,000 for the portion of Sacramento River and Major and Minor tributaries and $614,608 for Table Mountain (Iron Canyon) Dam and Reservoir, which are considered to be inactive.

FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1579 8. MIDDLE CREEK, CALIF. Location. Middle Creek, which has a drainage area of 200 square miles, is located in Lake County. It is tributary to Clear Lake, which flows into Cache Creek, a tributary of the Sacra- mento River. Scott and Clover Creeks are tributaries of Middle Creek near the town of Upper Lake. (See U. S. Geological Survey quadrangle for the Lakeport area.) Existing project. The improvement provides for enlargement of existing levees and the construction of additional levees and incidental channel improvement on Middle Creek for a total dis- tance of about 8 miles; a channel, about 11/2 miles in length, for diversion of Clover Creek floodflows to Middle Creek above the town of Upper Lake; and a levee on the left bank of Scott Creek from its mouth upstream for a distance of about 11/2 miles. Construction of the project will provide flood protection to about 5,000 acres of highly developed agricultural lands and to the town of Upper Lake. The latest approved estimate of Federal cost for new work (1957) is $1,400,000, for construction. Construction has not been initiated. The existing project was authorized by the Flood Control Act of September 3, 1954. (See H. Doc. 367, 81st Cong., 1st sess., which contains the latest published map.) Local cooperation. Local interests must give assurances satis- factory to the Secretary of the Army that they will provide with- out cost to the United States all lands, easements, and rights-of- way; hold and save the United States free from damage; and maintain and operate improvements after completion. The proj- ect has been officially adopted by chapter 1949, Statutes of 1955, State of California, and provides that the State Reclamation Board will give the required assurances. Lake County has formed the Lake County Flood Control and Water Conservation District for the purpose of working with the State Reclamation Board. Chapter 1396, Statutes of 1955, State of California, authorized that district to cooperate with the United States Government and the State in construction of the project. Formal assurances were requested of the State of California by Sacramento District letter of February 8, 1957. It is expected that these assurances will be furnished early in fiscal year 1958. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $1,240,000 (1957). Maintenance and operation of the project works after comple- tion will be the responsibility of local interests. The latest estimate (1957) of the cost to local interests for annual maintenance, operation, and the replacements is $16,900. Operations and results during fiscal year. Engineering was initiated during the fiscal year. Contract plans and specifications are being prepared by contract and are about 80 percent complete. Total cost of new work for the project during the fiscal year was $69,541. 1580 REPORT OF THE CHIEF OF ENGINEERS, U. S. RIMY, 1957 Condition at end of fiscal year. Preconstruction planning was initiated in fiscal year 1957. The hydrology and general design memos have been completed. Contract plans and specifications are about 80 percent complete. About 2,000 acres of farmland were flooded, extending from the reclamation district just above Clear Lake to and including the town of Upper Lake. The December 1955 flood caused agricul- tural damages and soil erosion; road surfacing was damaged and bridge abutments were eroded. Water reached a depth of 4 feet in the town of Upper Lake and flooded homes and business estab- lishments. If this project had been completed before the flood, it would have prevented all of the flood damages which occurred in the town of Upper Lake and in Middle Creek Valley, amounting to $334,000. Total cost to June 30, 1957, for the project was $69,541, for new work.

FOLSOM RESERVOIR, AMERICAN RIVER, CALIF. Location. Folsom Dam is on the American River about 21/x miles above or northeasterly of the town of Folsom in Sacramento County, Calif., about 1 mile below the confluence of the north and south forks of this stream, and about 20 miles upstream from the city of Sacramento. The reservoir extends from the dam up the main river to this confluence and about 14 niles farther upstream in each of the two forks. The American River system originates on the western slope of the Sierra Nevada, and' the main river flows into the Sacramento River at the city of Sacramento. The lower portion of the American River, 25 miles below Folsom, is in the Sacramento Valley. The drainage area of the river system contains 2,115 square miles of which 1,875 square mile are above the dam. (See U. S. Geological Survey quadrangles of the area. ) Existing project. The authorization provided initially for the construction of a dam, with gross storage capacity of 355000 acre-feet, and facilities for future power generation The proj- ect, as modified, consists of a multiple-purpose reservoir with' a storage capacity of 1,000,000 acre-feet in the joint interests of flood control, irrigation, municipal water supply and power gener- ation. The reservoir has been formed by construction of earth- FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1581 fill wing dams and a concrete gravity dam in the river channel with a gated spillway and with a maximum height of approxi-. mately 340 feet and crest length of 1,400 feet. The earthfill wing dams on each side of the river with a maximum height of 145 feet complete the closure, the crest length of the right wing dam is about 6,700 feet and the left wing dam about 2,100 feet. An earth- fill auxiliary dam is provided at Mormon Island, about 21/f miles easterly from the main dam, with a maximum height of 110 feet and a crest length of about 4,820 feet. Eight earthfill dikes, with a total crest length of approximately 11,700 feet and maximum height of 10 feet to 105 feet, close saddles in the reservoir per- imeter. Outlet facilities have been provided for irrigation and flood control releases and for power generation. Simultaneous construction of a hydroelectric powerplant at the dam site with power facilities of 162,000-kilowatt capacity, a downstream re- regulatory afterbay at Nimbus Dam with power facilities of 13,500-kilowatt capacity, and related transmission lines was ac- complished by the United States Bureau of Reclamation. The three generating units in the Folsom Powerhouse were placed on the line by the Bureau of Reclamation in May, October, and De- cemnber 1955. Folsom Dam was transferred to the Bureau of Reclamation on May 14, 1956, for operation and maintenance of the° project by that agency in conjunction with other units of the Central Valley project. The dam will also be operated for flood control in accordance with criteria established by the Secretary of the Army. The project will provide flood protection to the cities of Sacra- miento and North Sacramento and adjacent suburban areas, will make available annually about 500,000 acre-feet of new water for irrigation and municipal water supply and will make possible the generation of about 500,000,000 kilowatt-hours of electrical energy per year. The ltest approved estimate of Federal cost for new work (July 1956) is $63,019,000, of which $6,344,800 is for lands and damages, including relocations, and $56,674,200 for construction, including $4,898,000 for penstocks, trash racks, penstock face gates, and tailrace excavation constructed by the Corps of En- inpeers for and in coordination with the facilities built at the Folsom Dam by the Bureau of Reclamation. The latest estimate (January 1955) of the cost of the Federal facilities constructed by the United States Bureau of Reclamation is $38,020,000. Local interests will reimburse the United States for the conservation accomplishments of the project. The existing project was adopted by the Flood Control Act of December 22. 1944 (H. Doc. 649, 78th Cong., 2d sess.), which contains the latest published map, as modified by the American River Basin Development Act (Public Law 356, Oct. 14, 1949, 81st Cong., 1st sess.). Locai tobperation. None required, except payment for cost of conservation features when used. Conservation features of the project are to be'integrated into the Central Valley project of the United States Bureau of Reclamation. The State of California 1582 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 officially adopted the project by chapter 1514 of the Statutes of 1945, State of California. Operations and results during fiscal year. Minor engineering was accomplished by hired labor. Engineering and economic studies on relocation of Rattlesnake Bridge were accomplished by contract. Minor costs were incurred for land acquisition activi- ties. Purchase and installation of sump pumps and furnishing of auxiliary drainage pumps, initiated by two separate contracts in fiscal year 1956, were completed. Dewatering of the stilling basin and the grouting of Natoma Tunnel plug and backfilling of the tunnel portal were accomplished by contracts during the fiscal year. In addition, payment in lieu of relocation of Rattlesnake Bridge was accomplished. Total cost of new work during the fiscal year for the project was $731,013. Condition at end of fiscal year. Construction was initiated in October 1948 and completed in May 1956; minor construction and cleanup work remains to be accomplished. Land acquisition is completed with the exception of legal proceedings. Major items of work completed include construction of eight earthfill dikes; the Government administration and operations buildings; the main dam and appurtenances, including additional drilling and grouting, and the fabrication of tandem slide gates for the main dam outlet works and other appurtenant operating equipment; Mormon Island auxiliary dam including riprapping; relocation of North Fork Ditch Company and of Natoma Canal and appur- tenant facilities; reservoir clearing; relocation of Folsom-Auburn Road and of South Fork Road; and construction of South Fork Road, Sweetwater Creek section extension. Design and construction programs of the Corps of Engineers and the Bureau of Reclamation were coordinated to provide for orderly prosecution of the project; construction work accom- plished by the Corps of Engineers in the interest of power development was completed. The formal dedication of Folsom Dam and powerhouse was held on May 5, 1956. On May 14, 1956 the keys to the control tower of the dam were turned over to the Bureau of Reclamation, effecting the transfer of the dam to the Department of Interior for operating and maintenance. The three generating units in the Folsom powerhouse were placed on the line by the Bureau of Reclamation on the following dates: May 20, October 7, and December 1, 1955. During December 1955, the largest flood of record was com- pletely controlled, the reservoir storing about 670,000 acre-feet of water in 7 days, and preventing about $20,000,000 in damages. Further data pertaining to the prevention of these flood damages is reported under Improvement No. 10, "American River. Calif." A storage of 880,000 acre-feet was reached on May 14, 1956, com- pared to the capacity of 1,000,000 acre-feet, at which time the project was transferred to the Department of Interior for main- tenance and operation. The reservoir filled for the first time on June 23, 1956. FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1583 Legal proceedings in connection with land acquisition are to be completed.

AMERICAN RIVER, CALIF. Location. The American River, which drains an area of about 1,921 square miles of the Sierra Nevada, is one of the main tributaries of the Sacramento River. It joins the Sacramento River at the cities of Sacramento and North Sacramento. (See U. S. Geological Survey quadrangles Carmichael, Sacramento-east, and Sacramento-west.) Existing project. The project provides for construction of a levee on the right (north) bank of American River, in the vicinity of the city of Sacramento, Calif., for flood-control purposes. The project begins at an existing levee near the Elvas Bridge, and extends upstream along the right bank of American River about 7 miles to Carmichael Bluffs, near the town of Carmichael. Proj- ect construction includes reconstruction of a portion of an existing local interest levee and the provision of drainage facilities required to prevent excess ponding of runoff behind the levee. Construction was initiated in May 1957 and is 4 percent complete. The improvement is an integral part of the plan for flood con- trol for the city of Sacramento and environs, which plan includes Folsom Reservoir now in operation for flood control, power, and irrigation. Although the levee construction is not necessary to the power-production and irrigation functions of the reservoir, its operation for flood control will be restricted until releases of 115,000 second-feet can be made without causing damage along American River. The levee will provide flood protection to about 2,200 acres of land near the city of Sacramento, about 580 acres of which are currently devoted to suburban use, the remainder being agricul- tural land occupied largely by highly productive hop and truck farms. The latest approved estimate of Federal cost for new work (1957) is $2,190,000 for construction. 1584 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 The existing project was authorized by the Flood Control Act of September 3, 1954. (See H. Doc. 367, 81st Cong., 1st sess., which contains the latest published map.) Local cooperation. Local interests are required to provide all lands, easements, and rights-of-way necessary for the project; hold and save the United States free from claims for damages resulting from construction; and maintain and operate all project works after completion in accordance with regulations prescribed by the Secretary of the Army. The project has been officially adopted by chapter 321 of the Statutes of 1955, State of California. Local interests are represented by the Reclamation Board of the State of California. Assurances were furnished by the State Reclamation Board by letter dated October 3, 1956, and accepted by the Sacramento District on November 20, 1956, for the Secre- tary of the Army. All lands, easements and rights-of-way required for construction have been furnished. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contribution, amount to $750,000 (1957). Maintenance and operation of the project works after com- pletion will be the responsibility of local interests. Annual non- Federal cost of operation, maintenance, and replacement is estimated (1957) at $28,000. Operations and results during fiscal year. Engineering and design was continued by hired labor. Contract plans and specifi- cations were prepared by contract. Levee and pumping plant construction was initiated, by continuing contract, and is about 4 percent complete. Total cost of new work during the year for the project was $224,961, of which $224,536 was from Federal funds and $425 from contributed nonproject funds. Condition at end of fiscal year. Construction was initiated in May 1957; the project is about 13 percent complete. Levee and pumping plant construction is about 4 percent complete. The project is scheduled for completion in June 1958. Flooding on the American River by the December 1955 flood was confined to the mountainous areas above Folsom Reservoir; there was no flooding below Folsom Reservoir, despite the large volume of inflow. Although Folsom Dam was operationally complete at the time of the flood, the reservoir was nearly empty, and therefore was able to control the outflow to the present chan- nel capacity of about 70,000 cubic feet per second, and thereby protect the area below the reservoir from overflow. If the reser- voir had been up to the maximum permissible stage, the available flood-control space could not have controlled the outflow to the present channel capacity, and releases up to 115,000 cubic feet per second would have been required. Such a flow would have flooded about 2,200 acres of highly developed agricultural and suburban residential lands on the right bank of the river in the vicinity of H Street Bridge, and would have caused damages of about $1,000,000. If Folsom Reservoir had not been in operation during the flood it has been estimated that flood damages in the FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1585 order of $5,000,000 would have occurred on the right side of the river and about $15,000,000 on the left side of the river in the River Park residential area and downstream industrial area. Folsom Reservoir thus prevented about $20,000,000 in flood damages during the flood. The completion of the American River levee will permit maximum project releases of 115,000 cubic feet per second to be made from Folsom Reservoir without causing damage to the area between the reservoir and the city of Sacra- mento, thereby increasing the degree of protection to Sacramento and environs. -Total cost of new work to June 30, 1957, was $282,921, of which $282,496 was from Federal funds and $425 from contributed nonproject funds.

CALAVERAS RIVER AND LITTLEJOHN CREEK AND TRIBUTARIES, INCLUDING HOGAN AND FARMINGTON RESERVOIRS, CALIF. Location. The streams comprising the Calaveras River and Littlejohn Creek groups rise in the Sierra Nevada and its foot- hills, flow westerly across the flat lands of San Joaquin Valley and enripty into the San Joaquin River directly, or through various sloughs, in the vicinity of Stockton, Calif. The Littlejohn Creek group drains 487 square miles, of which 184 miles are below the base of the foothills; the watershed is located in Calaveras, Stanislaus, and San Joaquin Counties. The three principal stream 1586 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 systems of the group are, from south to north, Lone Tree Creek, Littlejohn Creek, and Duck Creek. This group is bounded on the south by Stanislaus River watershed, and on the north by the Calaveras River group. The Calaveras River group drains 173 square miles below the base of the foot hills and 560 square miles above. It is located in Calaveras and San Joaquin Counties, and is bounded on the south by Littlejohn Creek group watershed, and on the north by Mokelumne River watershed. The two principal streams of the group are, from south to north, Calaveras River and Bear Creek. The valley lands are essentially a delta area in which the streams of both groups are more or less interconnected by creeks and swales. (See U. S. Geological Survey Valley Springs quadrangle for Hogan Reservoir area and Trigo and Bachelor Valley quadrangles for Farmington Reservoir area.) Existing project. This consists of: a. Construction of Farmington Dam and Reservoir, with a gross storage capacity of 52,000 acre-feet, construction of a di- version channel from Duck Creek to Littlejohn Creek and of 2 dikes across downstream channels leading from Duck Creek to Mormon Slough, and enlargement of downstream Littlejohn Creek channels for the exclusive purpose of flood control. The reservoir is formed by an earthfill dam with a maximum height of about 58 feet and a length of about 7,800 feet; it is located on Littlejohn Creek 31/2 miles upstream from Farmington and about 18 miles easterly of Stockton, Calif. The outlet works are located in the right abutment and consist of two rectangular con- crete conduits, each 6 feet by 9 feet, controlled by slide gates, and a stilling basin. A concrete broad-crested weir approximately 95 feet long, located in the right abutment, serves as the spillway. Construction of the main dam and spillway was completed in June 1951. The Duck Creek diversion, located approximately 1 mile east of Farmington, comprises an earth dike across Duck Creek with two pipe outlets, an overflow concrete weir adjacent thereto, and a diversion channel approximately 5,000 feet long with a capacity of 2,000 cubic feet per second to Littlejohn Creek. The two dikes across the downstream channels are of earthfill con- struction and are located approximately 3 and 8 miles, respective- ly, west of Farmington. Duck Creek channel improvements were completed in November 1951. The Littlejohn Creek downstream channel improvement comprises an enlarged and improved chan- nel from the vicinity of Farmington to French Camp. The im- provement, consisting of clearing, channel excavation, and minor levee construction, was completed in April 1955. These improve- ments provide flood protection for about 58,000 acres of agricul- tural land, suburban areas, and industrial sites in the area immediately southeast of Stockton. The latest approved estimate of Federal cost for new work (1955) is $3,687,000, of which $1,140,400 is for lands and dam- ages including relocations and $2,546,600 for construction. Maintenance and operation of the dam, reservoir and appur- tenant gages are the responsibility of the Federal Government. The average annual maintenance cost during the past 5 years was FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1587 $6,495. Maintenance and operation of the channel improvements are responsibility of local interests. b. The New Hogan Reservoir provides for construction of a dam on Calaveras River to create a reservoir with a gross capacity of 325,000 acre-feet for flood control, irrigation, and related pur- poses. The dam will be an earthfill structure with maximum height of 200 feet and length of about 2,170 feet, together with four dikes having a combined length of about 1,400 feet and a maximum height of 20 feet. A gated spillway will be located near the south abutment of the dam. The improvement will be located on the Calaveras River, about 28 miles northeast of Stockton, California, at or below the site of the present small Hogan Dam, which is owned and operated by the city of Stockton for the partial flood-protection of that city. Construction has not been initiated. The project will provide adequate protection to the city of Stockton and adjacent urban areas, and to some 46,000 acres of contiguous agricultural lands. The project will also protect from floods originating on the Calaveras River access routes to important military installations in the Stockton area. In addi- tion, it will make available 62,000 acre-feet of new water annually for irrigation, required for the continued agricultural growth of the area, and will provide a potential municipal water source for Stockton and its industries. The latest approved estimate of Federal cost for new work (1957) is $19,300,000, of which $884,000 is for lands and damages, including relocations, and $18,416,000 for construction. Operation and maintenance of the project will be the responsi- bility of the Federal Government. Local interests will reimburse the United States for the conservation accomplishments of the project.

Sacramento, Calif., District-Flood Control. The levee and channel improvement of Bear Creek, San Joaquin County, an authorized unit of the entire project, is to be restudied and is excluded from the foregoing cost estimate. The cost of this unit was last revised in July 1954, and was estimated to be $705,000, for construction. The latest estimate (1954) of the cost to local interests for lands, damages, and bridges and utility relocations for this project unit is $573,000. 1588 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Maintenance and operation of the levee and channel improve- ments after completion will be the responsibility of local interests. The existing project was adopted by the Flood Control Act of December 22, 1944. (See H. Doc. 545, 78th Cong., 2d sess., which contains the latest published map.) Recommended modifications of project. In House Document 367, 81st Congress, 1st session, a plan of improvement was recom- mended which would provide for construction of a levee on the right bank of the Stockton diverting canal and incidental channel improvement, such work to extend from its source at Mormon Slough to its confluence with the lower Calaveras River. The recommended work would supplement the authorized Hogan Reservoir, and would control Calaveras River floods by confining regulated flows to leveed channels. The estimate of Federal cost for new work (1948) is $52,000. Local cooperation. None is required for construction of Farm- ington Dam and Reservoir. Payment for conservation storage in Hogan Reservoir, when used, is to be made to the United States by the State of California or other responsible agency. Arrange- ments for such repayment have not been undertaken as yet. The State of California has officially adopted the project by chapter 1514 of the Statutes of 1945, State of California. Assurances were furnished and all requirements have been com- plied with for the Duck Creek diversion structures and dikes. Duck Creek diversion structures and dikes were transferred to the State of California for maintenance and operation in June 1952. Assurances were furnished and all requirements have been complied with for the downstream Littlejohn Creek channel im- provement. The improved channel was transferred to the State of California for maintenance and operation on October 11, 1955. Total estimated costs for all requirements of local cooperation on the Duck Creek and downstream Littlejohn Creek improve- ments under terms of the project authorization, including required non-Federal contributions, amount to $319,300 (1955). Operations and results during fiscal year. New work: a. Farmington Reservoir: Minor engineering and office studies, minor costs in connection with legal proceedings for land acquisi- tion, and installation of Duck Creek gage were accomplished by hired labor during the fiscal year. The cost of new work for Farmington Reservoir during the fiscal year was $6,652. b. Hogan Reservoir: Engineering and design studies were resumed in Fiscal Year 1957. Surveys, field explorations, design memos, and cost allocation studies were accomplished by hired labor. In addition, engineering service contracts and rented equipment were utilized to accomplish additional surveys and field explorations. The cost of new work for Hogan Reservoir during the fiscal year was $277,830. c. Bear Creek (levee and channel improvement) : This project FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1589 is to be restudied and there were no operations nor costs during the year. Maintenance: Farmington Reservoir: Maintenance and opera- tion of the dam and outlet works and service facilities were ac- complished during the year by hired labor. In addition, peri- odic gage readings and other operational functions were also accomplished by hired labor. Runoff in the Littlejohn Creek basin during the year was below normal. With the exception of two short periods-March 1-9, 1957, and May 21-24, 1957, there was negligible storage, inflow and outflow. The maximum storage for the year, 2,700 acre-feet, occurred on March 6, 1957, while the May storage, although much smaller, was of interest due to its occurrence so late in the season. The reservoir was empty on July 1, 1956, and June 30, 1957. The peak flow in Duck Creek above the diversion works was about 550 cubic feet per second on March 5, 1957, of which about 450 cubic feet per second was diverted into Littlejohn Creek below the reservoir. The peak flow on Littlejohn Creek at the control station below the diversion was about 1,400 cubic feet per second on March 5, 1957. Total cost of maintenance for Farmington Reservoir during the fiscal year was $4,445 from Federal funds. Total costs for the entire project during the fiscal year were $288,927, of which $284,482 was for new work and $4,445 for maintenance. Condition at end of fiscal year. a. Farmington Reservoir: Construction of Farmington project was initiated in July 1949, and was completed for beneficial flood- control operation in calendar year 1952. The following major features have been completed: Construction of outlet works, in- cluding installation of slide gates and appurtenances; main dam and spillway in June 1951; Duck Creek Channel improvement in November 1951; relocations of necessary roads and utilities; in- stallation of gaging facilities; construction of embankment slope protection, relief wells, and upstream connecting channel between Littlejohn Creek and Rock Creek; and channel improvement on south Littlejohn Creek, May 1955. The reservoir, Duck Creek diversion facilities, and channel improvement of Littlejohn Creek are in operation. Condition of the dam and appurtenances is good. Approximately 2 miles of road are maintained: by the Corps. Condition of the road is good. There are no recreation facilities and no public-use areas. During December 1955, the largest flood of record was regulated to practically nondamaging flows. About 32,000 acre-feet of space was filled in 2 days. The maximum storage of record, 32,000 acre-feet, occurred on December 24, 1955. The peak flow in Duck Creek above the diversion works was about 2,600 cubic feet per second, of which about 2,400 cubic feet per second was diverted into Littlejohn Creek below the reservoir. That inflow exceeded the estimated preproject peak flow of 2,500 cubic feet per second in February 1917. The peak flow on Littlejohn Creek at the control station below the 'diversion was about 2,750 cubic 1590 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 feet per second. Flooding in the Littlejohn Creek area amounted to about 1,800 acres of which about 1,400 acres were on the south branch of the creek between Mariposa Road and Van Allen Road, and about 400 acres were on the north branch of the Creek at United States Highway No. 99. Farmington Reservoir controlled Littlejohn Creek inflows to safe channel capacity, but the uncon- trolled flow from Duck Creek, through the Duck Creek Diversion Channel, was more than the lower creek channels could carry. There was no flooding on Duck Creek from Duck Creek water. Flooding along lower Duck Creek was from Mormon Slough water, and the damage from this overflow has been included with that of Calaveras River. Flood damages below Farmington Reservoir amounted to $30,000; there were no flood damages above the reservoir. The operation of Farmington Reservoir reduced the December flood flow on Littlejohn Creek below the Duck Creek Diversion from about 22,400 cubic feet per second to about 2,700 cubic feet per second. This operation prevented flood damages of about $2,200,000 in the December 1955 flood and $300,000 in the January 1956 flood. Total cost of new work for Farmington project to June 30, 1957, was $3,751,501, of which $3,643,445 was from United States funds and $108,056 from contributed funds. Total cost of maintenance for Federal operation and mainte- nance of the Farmington Reservoir and appurtenant gages was $32,471 from United States funds between July 1952 and June 30, 1957. b. Hogan Reservoir: Preliminary definite design studies have been prepared for selection of reservoir capacity and a survey and preliminary geological investigations of the dam site have been made. Dam and appurtenances memorandum is about 40 percent complete, general design memorandum is about 47 percent complete, and preliminary cost allocation is about 50 percent complete. Construction has not been initiated. Total cost of new work for Hogan Reservoir to June 30, 1957, was $400,011 from Federal funds. The existing Hogan Reservoir, constructed and operated by the city of Stockton, effectively reduced floodflows and flood damages during the floods of December 1955-January 1956. The damages prevented by this project have not been evaluated in detail, but they were substantial; probably in the order of $10,000,000. Without the flood control provided by Hogan Reser- voir, a much larger part of the city of Stockton and of the adjacent suburban area would have been flooded, and the flood damages would have been correspondingly larger than actually occurred. If the authorized project had been completed and in operation, it would have prevented flood damages of approximately $2,000,000 which occurred in and near the city of Stockton. The authorized project would also have helped to reduce the damages which occurred in the delta area. c. Bear Creek (levee and channel improvement) : This project is to be restudied. During the December 1955 flood, Bear Creek FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1591 overflowed its banks to flood about 7,000 acres of land, from a point above Jack Tone Road down to the Davis Road northwest of Stockton. The flood damages totaled $239,000. The project would have prevented all flood damages caused by the December flood. Total costs for the entire project to June 30, 1957, were as follows: New work Maintenance Total Funds costs costs costs United Statesfunds.....------------------------ $4, 043,456 $32,471 1$4, 075,927 Contributed funds (nonproject)............ 108,056- .---.-. -- 108,056 Total-------------------------------- 4,151,512 32,471 4,183,983 1 Excludes costs of $17,057 for Bear Creek Channel improvements (deferred for restudy).

LOWER SAN JOAQUIN RIVER AND TRIBUTARIES, INCLUDING TUOLUMNE AND STANISLAUS RIVERS, CALIF. Location. The San Joaquin River has its sources in the Sierra Nevada, r and flows generally southwest through the mountains and 1592 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 foothills to the vicinity of Friant, where it enters the flat alluvial valley through which it flows west 60 miles to Mendota midway of the valley floor. At Mendota the river turns northwest and flows 149 miles to Mossdale at the head of the San Joaquin Delta, an extensive area of reclaimed tidal swamplands through which the river flows with numerous side channels and sloughs to join the Sacramento River at the head of Suisun Bay near Pittsburgh. The river drains an area of 17,000 square miles. The Tuolumne and Stanislaus Rivers, two of the principal tributaries of the San Joaquin River, likewise have their sources in the Sierra Nevada, and flow in a generally westerly direction through the mountains and foothills to enter the alluvial valley and join the main river from the east in its lower reaches. Stockton, at the head of the delta, and Fresno, just south of the San Joaquin watershed, are the principal commercial and distributing centers serving the area under consideration. (See U. S. Geological Survey quad- rangles of the area.) The lower San Joaquin River is under im- provement for navigation, the existing project providing for a 30-foot ship channel to Stockton and various minor improvements for the benefit of light-draft navigation in the delta channels. Existing project. This improvement provides for: a. Construction of New Melones Dam and Reservoir, on the Stanislaus River about 45 miles easterly of the city of Stockton, and about 25 miles upstream from the town of Oakdale, to create a reservoir with a gross storage capacity of 1,100,000 acre-feet for flood control, irrigation, and other related water conservation purposes. The dam will be located about three-quarters of a mile downstream from the existing Melones Dam, which is owned and operated by the Oakdale and South San Joaquin Irrigation Dis- tricts. It will be located in Calaveras and Tuolumne Counties and will be of concrete gravity type about 482 feet high and 1,140 feet long, with a gated overflow spillway located in the center of the dam. Facilities will be provided in the dam for a proposed downstream powerplant to replace the existing powerplant. Construction has not been initiated. New Melones Reservoir will provide needed protection from flooding by Stanislaus River to 25,000 acres of agricultural lands lying along the valley reaches of Stanislaus River, and to suburban areas of small communities. In addition to the flood-control bene- fits, the project will provide some 175,000 acre-feet of new water annually for irrigation and related purposes. It will also provide sufficient water for generation of about 321,000,000 kilowatt hours of additional usable power when a power plant is authorized. In conjunction with storage projects on Tuolumne River and the authorized levees for the San Joaquin River, the project will pro- vide a high degree of flood protection to the bottom land along the San Joaquin River below the Stanislaus River and to tracts in the upper delta. Two mainline railroads, United States Highway No. 99 and important roads crossing the Stanislaus River, and railroads and highways crossing the San Joaquin River will be protected. The latest approved estimate of Federal cost for new work FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1593 (1957) is $76,700,000, of which $14,285,000 is for lands and damages including relocations and $62,415,000 for construction including proposed powerplant. Maintenance and operation of the dam and reservoir are the re- sponsibility of the Federal Government; the latest (1957) esti- mate for annual Federal cost of this maintenance and operation, including replacements is $347,000. Local interests will re- imburse the United States for the conservation accomplishments of the project. b. An expenditure toward the first cost of Cherry Valley Reser- voir and the New Don Pedro Reservoir in the Tuolumne River Basin. Federal interest in the development is in the flood protec- tion to be afforded by reservoirs constructed by local interests, comprising the city and county of San Francisco and the Turlock and Modesto irrigation districts; the Federal Government will contribute toward first cost of the construction an amount com- mensurate with the flood-control benefits to be derived. The Federal Government has contributed a total of $9,000,000 toward construction through June 30, 1957. Ultimately the flood pro- tection will be derived from the operation for flood control of at least 340,000 acre-feet of storage in the New Don Pedro Reservoir, proposed for a total capacity in the order of 1,200,- 000 acre-feet. First phase of the development by local interests is the construction for municipal water supply, power genera- tion, and other purposes of the Cherry Valley Reservoir, in the upper Tuolumne River watershed, about 25 miles east of the town of Sonora, Calif. The dam is a composite earth and rock embankment 315 feet high and about 2,500 feet long, which creates a reservoir with a capacity of 268,000 acre-feet below the spillway crest. The local interests will operate this reservoir and the existing Hetch Hetchy and Don Pedro Reservoirs for flood control until such time as the New Don Pedro Reservoir is constructed and placed in operation. This improvement is an integral unit of the authorized plan for flood control in the San Joaquin River Basin; operation of the Tuolumne River Reservoirs will provide flood pro- tection to about 8,000 acres of agricultural lands and several communities along the Tuolumne River. The latest approved estimate (1957) of the Federal contribu- tion toward the first cost of the Cherry Valley Reservoir is $9,255,000, including $255,060 incidental Federal costs, in return for that portion of the ultimate contribution justified by the degree of flood protection provided. The latest approved estimate (1957) of the total Federal contribution toward the first cost of the Tuolumne River Reservoirs is $12,340,000, including $340,000 incidental Federal costs. c. A levee and channel improvement project located on the San Joaquin River and major tributaries upstream of the delta near Stockton, Calif. It provides for improvement of the existing channel and levee system on the San Joaquin River upstream from the delta to the mouth of the Merced River, and on the lower reaches of the Stanislaus and Tuolumne River by raising and strengthening the existing levees; construction of new levees; revetment of river banks where required; removal of accumulated 1594 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,. 1957 snags in the main river channel; and for the acquisition, by local interests, of flowage rights on natural overflow lands where neces- sary to insure continued effectiveness of channel storage on the San Joaquin River. Public Law 327, 84th Congress, 1st session, approved August 9, 1955, modified the project to permit local in- terests to construct levees and channel improvements upstream from Merced River, when required, in lieu of acquiring flowage easements. The local interests' plans of improvement will be coordinated with that of the Federal Government. Construction was initiated in July 1956 and is 7 percent complete. This project is an integral unit of the authorized plan for flood control and other purposes in the San Joaquin River Basin; it is designed to supplement the reservoir units of the overall plan, in- volving flood control storage on the Tuolumne and Stanislaus Rivers and in the existing Friant Reservoir on the upper San Joaquin River, by providing channel capacities along the San Joaquin River sufficient to safely pass regulated flows. The levee and channel improvement project, together with the reservoir units, will provide urgently needed flood protection to a rich agricultural area of approximately 140,000 acres, to numerous commercial and public installations, and to a suburban area adjacent to the city of Stockton. The latest approved estimate of Federal cost for new work (1957) is $11,900,000, for construction. The existing project was adopted by the Flood Control Act of December 22, 1944. (See H. R. Flood-Control Committee Doc. 2, 78th Cong., 2d sess., which contains the latest published map.) The 1944 Flood-Control Act authorized $8,000,000 for partial accomplishment of the project. Further monetary authorizations of $2,500,000 and $5,000,000 were provided for this project by Public Laws 235, 83d Congress, 1st session, and 780, 83d Congress, 2d session, making a total monetary authorization of $15,500,000 available. Recommended modifications of project. In House Document 367, 81st Congress, 1st session, it was recommended that power- generating facilities, not now included in the authorized project, be constructed concurrently with and as part of New Melones Dam. For an initial installation of 41,000 kilowatts, the first cost was estimated (1948) at $4,727,000, and the annual cost of maintenance and operation at $194,400. Local cooperation. a. New Melones Reservoir (Stanislaus River) : The State of California or other responsible agency will be required to pay for the conservation storage when used. Such payment will be based upon future cost allocation studies by the Department of the Army. The State of California has officially adopted the project by chapter 1514, Statutes of State of California, 1945. b. In Tuolumne Basin: Local interests are to construct, main- tain, and operate the dams and reservoirs, allocate storage for flood control, and agree to operate such storage in accordance with rules and regulations prescribed by the Secretary of the Army. Local interests have agreed by means of a negotiated contract to FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1595 construct, maintain, and operate in the interest of flood control, the Cherry Valley Reservoir, as well as allocate flood control storage space in their existing facilities until such time as the New Don Pedro Dam and Reservoir are constructed by local interests and flood control storage is provided therein. Local interests have been operating their existing reservoirs for flood control since December 1949 in accordance with applicable regulations and the above cited contract. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non- Federal contributions, amount to $5,000,000 for Cherry Valley Reservoir and $67,000,000 for New Don Pedro Reservoir, a total of $72,000,000 (1955). c. San Joaquin River: For improvement downstream from the mouth of Merced River, the State of California or other re- sponsible local agencies must furnish assurances satisfactory to the Secretary of the Army that they will: (1) furnish flowage rights to overflow certain lands along the main San Joaquin River, and all lands, easements, and rights-of-way necessary for construc- tion of levees; (2) hold and save the United States free from dam- ages due to the construction works in the San Joaquin River and tributary channels, and their subsequent maintenance and opera- tion; and (3) maintain all levees and channel improvements after completion in accordance with regulations prescribed by the Secretary of the Army. In addition, local interests must bear the cost of improvements as required along the San Joaquin River upstream from the mouth of Merced River. Chapter 1514, Statutes of State of California, 1945, provides for furnishing the requirements for the levee and channel im- provement work. Chapter 1048, California Statutes of 1955 amended the Water Code and approved the execution of a plan which includes provisions for the State to construct levee and channel improvement works above the mouth of Merced River, as required, in lieu of furnishing flowage easements, to protect such lands against floods. Local interests are represented by the Reclamation Board of the State of California. The required assurances were furnished December 21, 1955, and accepted January 6, 1956, by Sacramento District, Corps of Engineers, for the Secretary of the Army. All lands, easements and rights-of-way have been furnished by the State of California as required to date, in accordance with the above assurances. Requirements for future construction will be furnished as needed. Maintenance and operation of the levee and channel improve- ments after completion are the responsibility of local interests. The latest estimate (1957) of annual cost to local interests is $168,000. The latest estimate (1957) of the cost to local interests is $3,200,000, below the mouth of the Merced River, for lands, damages, and relocations. Estimated cost to local interests for limited reclamation above the mouth of Merced River in lieu of acquisition and flowage easements is $5,000,000 (1957). 1596 REPORT OF THE CHIEF OF ENGINEERS, 'U. S. ARMY 1957 Operations and results during fiscal year. New work. a. New Melones Reservoir (Stanislaus River): Engineering and design was resumed in fiscal year 1957. Design and office studies, surveys, field explorations, and economic studies were accom'- plished by hired labor during the fiscal year. The economic feasibility report for the project was completed. Total cost of new work for New Melones Reservoir during the fiscal year was $59,840. b. Cherry Valley Reservoir, Tuolumne River Basin: Final payment of the Federal contribution toward the cost of Cherry Valley Reservoir was made during fiscal year 1957. Minor office engineering was accomplished by hired labor. Construction of Cherry Valley Reservoir was completed in fiscal year 1957 by the contractors, the city and county of San Francisco, and the Turlock and Modesto Irrigation Districts. The contractors also continued to operate their existing Don Pedro Reservoir facilities for flood control. Total cost of new work for Cherry Valley Reservoir during the fiscal year was $66,292. c. Construction of levee and channel improvement works on Lower San Joaquin River and tributaries: Engineering, including surveying and mapping and preparation of contract plans and specifications, was continued by hired labor. Construction was initiated on this project in fiscal year 1957. Stone protection along the right and left banks of San Joaquin River, from head of Old River to Brandt Bridge in San Joaquin County and from the vicinity of Brandt Bridge to Stockton Channel, was accomplished during the year under two separate contracts. Total cost of new work for the levee and channel improvement works on Lower San Joaquin River was $949,673, of which $850,881 was from Federal funds and $98,792 from contributed nonproject funds. The total cost for the entire project during the fiscal year for new work was as follows: Federal Contributed Project funds funds 1 Total New Melones Reservoir, Stanislaus River-_ $59, 840 ----- .----- $59, 840 Tuolumne River Basin Reservoirs, includ- ing Cherry Valley Reservoir ........... 66,292 .. - 66,292 Lower San Joaquin River and tributaries_ 850,881 $98,792 949,673 Total -------------------------------- 977,013 98,792 1,705,805 1 Contributed funds for miscellaneous engineering and construction (nonproject) at the expense of local interests in connection with acquisition of rights-of-way for Lower San Joaquin River and Tributaries.

Stanislaus River: Engineering accomplished consists of collection of data for design memoranda, including topographic surveys and hydrologic data, consideration of its interrelationship with other units in the comprehensive plan, revision of project costs and benefits, and the preparation of preliminary plans. The economic feasibility report has been completed; hydrology design FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1597 memorandum is about 80 percent complete. Construction has not been initiated. On- December 21, 1955, there was about 90,000 acre-feet of available storage space in the 112,000 acre-feet capacity existing Melones Reservoir, which is operated by the South San Joaquin and Oakdale Irrigation Districts. Inflow to the reservoir began to increase in the early hours of December 22 and reached a peak of about 100,000 cubic feet per second by 5 a. m. on the 23d, which exceeded the previous record peak inflow of about 90,000 cubic feet per second in 1950. On the morning of the 23d, the reservoir was full and began to spill. The peak outflow of about 62,800 cubic feet per second at about 3 p. m. on December 23 exceeded the previous record peak flow of about 49,000 cubic feet per second in 1950. At Ripon, the peak flow was about 65,000 cubic feet per second on December 24, which exceeded the previous record peak flow of about 48,000 cubic feet per second at that point in 1950. Persistent stormy weather during January and February 1956 kept river flows high, with occasional moderate peaks. These flows were generally controlled by the existing Melones Reservoir, except during the storm of January 12 and 13 when the reservoir spilled a maximum of about 13,000 cubic feet per second on January 16th. The flow caused some renewed flooding through damaged levees near the mouth of the river. The areas inundated by the December 1955 and January 1956 floods extended from the foothill line near the community of Knights Ferry to San Joaquin River. Below Ripon, floodwaters of Stanislaus River intermingled with those of San Joaquin River, and a large area was inundated. Compared with the 1950 floods, these floods inundated more land above Ripon and slightly less below Ripon, and flooding north of the river was not as large. The flooded area totaled about 15,100 acres, which was practically the,same total as reported for the 1950 floods. The flooded lands are highly productive and intensively cultivated. The towns of Ripon, Riverbank, and Oakdale, which are located on high ground adjacent to the river, were flooded only to a minor extent. The historical community of Knights Ferry was flooded. About 85 percent of the total damage was caused by the December 1955 flood and about 15 percent by the January 1956 flood. If the New Melones Reservoir had been completed and in operation during the flood period, it would have prevented all of the damages which occurred below the existing Melones Dam, amounting to about $1,928,000, and would also have aided ma- terially in reducing the damages which occurred along the lower San Joaquin River. Total cost for New Melones Reservoir to June 30, 1957 is $122,995. b. Cherry Valley Reservoir, Tuolumne River Basin: Engi- neering and design studies, including preparation of flood-control- operation criteria, review and approval of plans prepared by the ontractor,: and design analyses, have been accomplished. Under the terms of a contract awarded in fiscal year 1950, to the city and county of San,Francisco and the Turlock and Modesto 1598 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Irrigation Districts, modification of existing facilities as necessary at Don Pedro, Hetch Hetchy, and Lake Eleanor Reservoirs was accomplished. The contractors have been operating the existing reservoir facilities for the flood control in accordance with regu- lations of the Secretary of the Army for flood-control purposes (phase I of the project). Construction of Cherry Valley Reservoir (phase II) was ini- tiated in September 1950, and was sufficiently completed to act as a detention dam and to provide incidental reduction of down- stream flows during the floods of December 1955-January 1956. The reservoir was completed in Fiscal Year 1957. Construction of New Don Pedro Reservoir (phase III) remains to be accomplished; and is scheduled for completion in 1964. On December 21, 1955, there was about 515,000 acre-feet of available space in the Tuolumne River reservoir system, of which about 205,000 acre-feet were in Don Pedro Reservoir and the remainder in the upstream Hetch Hetchy, Cherry Valley, and Lake Eleanor Reservoirs. By December 23, Hetch Hetchy and Cherry Valley Reservoirs had stored about 130,000 acre-feet of floodwater with complete control and Lake Eleanor was full and passing, inflow. The inflow to Don Pedro Reservoir began to increase rapidly on December 22, virtually filling the reservoir by 12:00 p. m. on the 23d, and the outflow increased from about 2,000 cubic feet per second to a peak of about 42,000 cubic feet per second at 9:00 a. m. on the 24th. Downstream flows were all less than the record flows in December 1950, which were about 61,000 cubic feet per second at La Grange Dam and 57,000 cubic feet per second at Modesto. About 7,100 acres of agricultural land were inundated by the December 1955 flood. Above Don Pedro Reservoir, about $90,000 in damages were reported, mainly to county roads and bridges. Below Don Pedro Reservoir, the river flooded and damaged agri- cultural areas along the river, sewage and water facilities of the city of Modesto, and a few residences on the southwestern fringe of Modesto. These flood damages amounted to about $549,000. At the time of the flood, the recently constructed, but not com- pleted Cherry Valley Reservoir, stored about 43,000 acre-feet of floodwater. Under the initial plan of the project, 100,000 acre- feet of space in Don Pedro Reservoir was operated for flood control. This operation, in conjunction with the incidental flood protection provided by the existing reservoirs, materially reduced the amount of the flooding in Tuolumne River Valley, and lessened the peak contribution to San Joaquin River. The operation of the Federal-interest storage prevented damages of about $3,000,000 along Tuolumne River, along the lower San Joaquin River, and in the upper delta. The project also provides for the operation of 340,000 acre-feet of flood-control space in the New Don Pedro Reservoir, to be constructed by local interests. Operation of that space would have controlled the December 1955 flood to nondamaging channel capacities, and would have prevented damages amounting to about $549,000. New Don Pedro Reservoir, in conjunction with the FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1599 authorized New Melones Reservoir Project and the Lower San Joaquin River levee project, with some incidental flood-control assistance from the Tri-Dam project (a private conservation and power development project currently under the construction on the Stanislaus River), would have prevented damages along San Joaquin River estimated at $1,459,000. The initial Federal contribution was made in 1950 and total costs for Cherry Valley Reservoir to June 30, 1957, were $9,229,882, consisting of $9,000,000 as direct payments to local interests and $229,882 for incidental Federal costs. c. Construction of levee and channel improvement works on lower San Joaquin River and tributaries: Construction was initiated in July 1956; the project is about 7 percent complete. Data for definite design studies have been assembled, including studies of existing channel capacities, topographic surveys, re- connaissance of existing levees, derivation of project design flood plan, and determniation of potential benefits. General design memorandum is complete. Cooperative studies with the State of California have been made to determine plans for preservation of natural valley storage above Merced River. Stone protection along San Joaquin River, from head of Old River to Brandt Bridge and from the vicinity of Brandt Bridge to Stockton Channel, in San Joaquin County, has been completed. Work remaining to be done includes completion of levees and initiation and completion of channel improvements. During the floods of December 1955-January 1956 floodflows along the lower San Joaquin River were high for a prolonged period, but in general were considerably less than the flows in 1950. The peak flow from the several tributaries did not coincide, and the peak flows measured at key gaging stations along the main river resulted principally from the peak outflow of the nearest upstream tributary. Continued stormy weather, and evacuations of floodwater stored in the several tributary reservoirs, main- tained high stages along the entire length of the river until March 19, 1956, when flows at Vernalis finally dropped below 10,000 cubic feet per second. In the area between the mouth of Merced River and Mossdale (at the head of the delta), floodwater from San Joaquin River intermingled with floodwater from Merced, Tuolumne, and Stanis- laus Rivers to flood about 25,500 acres of valley-flood lands on both sides of the river. The area included in the upper delta extends from the Mossdale Bridge (at the head of the delta islands on San Joaquin River) to a line about 8 miles west, which has been established as the practical limit of tidal effects. Flooding from overflow was negligable, but it was reported that on several islands a total of about 8,400 acres were inundated from seepage. The streams included in the west side tributaries are Los Banos Creek, Orestimba Creek, and Marsh Creek. A total of about 10,700 acres were flooded by this group. In the reach from Merced River to Mossdale, damages totaled $1,854,000. Damages in the upper delta were caused mostly by seepage, were all agricultural, and totaled about $168,000. Flood 1600 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,. 1957 damages on the west side tributaries totaled $447,000. Total flood damages on the lower San Joaquin River project were $2,469,000. The following existing reservoirs had a significant effect on flood flows and flood damages on the lower San Joaquin River reaches: Friant Reservoir on upper San Joaquin River; Exchequer Reser- voir on Merced River; the existing Don Pedro Reservoir on Tuolumne River; Hetch Hetchy Reservoir on Tuolumne River; Cherry Valley Reservoir on Tuolumne River; and the existing Melones Reservoir on Stanislaus River. No accurate determina- tion has been made of the effect on flooded areas and flood damages that these reservoirs had on the lower San Joaquin River area and the upper delta area, but there is no doubt that the damages prevented were very substantial, amounting to several million dollars. When the authorized work on the lower San Joaquin River is completed, flows in San Joaquin River below the mouth of Merced River will be generally confined by levees. Some incidental flood protection will be provided for the area between the mouth of Stanislaus River and Mossdale by the Tri-Dam project, a private conservation and power development currently under construction on Stanislaus River. Of the $1,854,000 damages incurred along the reach from Merced River to Mossdale, about $395,000 were above the mouth of Tuolumne River on areas which would still be subject to flooding after completion of the authorized project. Damages of about $1,459,000 would be prevented by the authorized project in conjunction with the Tri-Dam project. There are no authorized projects on streams in the west-side tributaries group. The total costs for the entire project to June 30, 1957, for new work were as follows: Federal Contributed Project funds funds 1 Total New Melones Reservoir, Stanislaus River $122,995 ...... ..._ _ $122,995 Tuolumne River Basin Reservoirs, includ- ing Cherry Valley Reservoir .___________ 9,229,882 _____________ ___ 9,229,882 Lower San Joaquin River and tributaries 1,309,019 $100, 110 1,409,129 Total ______________ _____________ 10,661,896 100,110 10,762,006 1 Contributed funds for miscellaneous engineering and construction (nonproject) at the expense of local interests in connection with acquisition of rights-of-way for Lower San Joaquin River and Tributaries.

MERCED COUNTY STREAM GROUP, CALIF. Location. The streams comprising the Merced County stream group rise in the Sierra Nevada foothills of the Central Valley of California and flow in a general westerly direction to join the San Joaquin River west of the city of Merced. The streams form three general groups; Bear Creek with its tributaries, Black Rascal Canal, Fahrens and Burns Creeks; Mariposa Creek with its tributaries, Miles and Owens Creeks; and Deadmans Creek with its tributaries, Little Deadmans, Big Deadmans, and Dutchmans Creek. The latter group crosses an area of pasture land and flood-control improvements are not provided for this group. The remainder of the Merced County stream group drains an upper area of 398 square miles, ranging from mountains to low foothills, and a lower area of 312 square miles of broad alluvial valley. The flow of the streams of the Merced County group is inter- mittent. (See U. S. Geological Survey Haystack Mountain quad- rangle for Burns Reservoir area and Indian Gulch quadrangle for Bear, Owens, and Mariposa Reservoirs areas.) Existing project. Improvement of Merced County stream group is a unit in the comprehensive plan for flood control and other purposes in the Sacramento-San Joaquin Basins. The proj- ect consists of four retarding-type reservoirs and provides for channel improvements, in the vicinity of the city of Merced, Calif., for the exclusive purpose of flood control. Mariposa Dam, completed in November 1948, comprises an earthfill main dam 1,300 feet long with a maximum height of about 88 feet and two auxiliary dikes aggregating 1,375 feet in length; the reservoir has a gross storage capacity of 15,000 acre-feet; the spillway is located in a saddle near the left abutment of the main dam. The dam is located on Mariposa Creek about 18 miles east of Merced. Owens Dam, completed in October 1949, consists of an earthfill main dam with a maximum height of 75 feet and a crest length of 1602 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 790 feet and an auxiliary dike approximately 370 feet long in a saddle near the left abutment; the gross storage capacity of the reservoir is 3,600 acre-feet; the spillway is located in a saddle near the left abutment of the auxiliary dike. Owens Dam is located on Owens Creek about 16 miles east of Merced. Burns Dam, completed in January 1950, is an earthfill structure with a maximum height of 55 feet and a crest length of 4,075 feet; a low auxiliary dike about 290 feet long is located in a saddle near the left abutment; the reservoir has a gross storage capacity of 7,000 acre-feet; the spillway is located near the right abutment. Burns Dam is located on Burns Creek about 13 miles northeast of Merced. Bear Dam, completed in December 1954, is an earthfill structure with a maximum height of 92 feet and a crest length of 1,830 feet; an ungated saddle spillway; and an auxiliary dike about 290 feet long; the reservoir has a gross storage capacity of 7,700 acre-feet. Bear Dam is located on Bear Creek about 15 miles northeast of Merced. Diversion of flow from Black Rascal Creek to Bear Creek was accomplished by means of a 3,000 second-foot capacity canal with a length of 1.3 miles, and diversion of flow from Owens Creek to Mariposa Creek, by means of a 400 second-foot capacity canal with a length of 1.6 miles. These improvements were completed in April 19.56 and are located east of Merced 4 and 11 miles, respectively. In addition, channel enlargement of a constricted portion of Miles Creek and restoration of impaired channel capacities of Burns, Owens, and Mariposa Creeks was accomplished in 1956 by responsible local interests at their expense. Improvement of Bear Creek and Black Rascal Slough, below their confluence, has been deferred pending possible improvements downstream, outside the limits of the project. The project will provide flood protection to about 136,000 acres of agricultural lands, to the city of Merced, to the towns of Planada and Le Grand and other smaller communities, and to highway and transportation facilities. The latest approved estimate of Federal cost for new work (1955) is $2,764,000 for construction. Operation and maintenance of the project and the existing chan- nel improvements is the responsibility of local interests. Opera- tion and maintenance of the reservoirs and appurtenant gaging facilities is the responsibility of the Federal Government. The average annual maintenance cost during the past 5 years was $11,020. The existing project was adopted by the Flood Control Act of December 22, 1944. (See H. Doc. 473, 78th Cong., 2d sess., which contains the latest published map.) Local cooperation. Construction of the project was subject -to the conditions that the State of California or other responsible local agencies give assurances satisfactory to the Secretary of the Army that they would (1) provide without cost to the United States all land, easements, and rights-of-way necessary for the FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1603 construction; (2) bear the expense of all necessary highway and utility changes; (3) complete the enlargement of the channel of Miles Creek and restore the channel capacities of Black Rascal, Burns, Bear, Owens, and Mariposa Creeks in accordance with , the plan of the district engineer; (4) hold and save the United States free from damages resulting from construction of the works; and (5) except for the reservoirs, dams, and appurtenant gages, main- tain and operate the completed project works and existing channel in accordance with regulations prescribed by the Secretary of the Army. Chapter 1514, Statutes of State of California, 1945, pro- vided for the furnishing of the required assurances which were furnished and accepted by the Secretary of the Army on January 22, 1948. All lands, easements, and rights-of-way have been furnished by the State of California as required, in accordance with the above assurances. Senate bill 1659, chapter 1118, Statutes of State of California of 1953, authorized the State reclamation board to provide the enlargement and restore the channel capacities of the creeks enumerated in (3) above. This work was completed in fiscal year 1956, with the exception of improvement of Bear Creek and Black Rascal Slough below their confluence, which has been deferred pending possible improvements downstream, outside the limits of the project. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $737,000 (1955). Operations and results during fiscal year. New work: Minor engineering and preparation of operation and maintenance manuals was accomplished by hired labor. Sedimentation range survey and other related data for Bear Reservoir was accom- plished by contract. Construction of a gaging station on Bear Creek below Bear Reservoir was accomplished by contract. In addition, local interests completed the channel enlargement of Miles Creek and the restoration of channel capacities of Burns, Owens, and Mariposa Creeks at their expense as a part of the requirements of local cooperation. Maintenance: Maintenance and operation of the dams and reservoirs, and service facilities and condition and operation studies, including periodic gage reading and other operational functions, were accomplished throughout the fiscal year by hired labor. Riprapping of the outlet works at Bear Dam was accomplished by contract. -During the year, the runoff from the drainage areas above the Merced County stream group reservoirs was below normal. With the exception of three short periods-February 24-27, 1957, March 1-4, 1957, and April 18-20, 1957, there was negligible storage, inflow, and outflow at all of the reservoirs. The maxi- mum storage for the system occurred on February 25, 1957, with Mariposa storing 360 acre-feet, and the other reservoirs storing> smaller quantities. Minor flows were produced in both the Owens-Mariposa Diversion channel and the Black Rascal-Bear 1604 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Diversion channel. The flows in Black Rascal, Fahrens, Deadman, and Dutchman Creeks are uncontrolled and not recorded. Total cost of new work for the project during the fiscal year was $17,202. Total cost of maintenance for Federal operation and mainte- nance of the four completed reservoirs and appurtenances during the fiscal year was $15,208. Total cost of all work for the project during the fiscal year was $32,410. Condition at end of fiscal year. Construction under this im- provement is completed and was initiated in March 1948, with the construction of Mariposa Dam and Reservoir, which was completed in November 1948. Construction of Owens Dam and Reservoir, initiated in March 1949, was completed in October 1949, and Burns Dam and Reservoir, initiated in July 1949, was com- pleted in January 1950. Bear Dam and Reservoir, initiated in April 1954, was completed in December 1954. Black Rascal and Owens Creek Diversion Channels and stream gaging stations were completed in April 1956. The Master Manual of Reservoir Regulations for San Joaquin Basin, Calif., and appendix III there- to covering the Merced County stream group project, and the maintenance manuals have been completed. During the disastrous flood of December 1955, all of the Merced County stream group reservoirs filled to capacity and spilled moderate amounts of water. This is the first time any of the reservoirs has filled. Flows on all of the principal streams of the group were outstanding in both peak and volume. Although the volumes of inflow to all of the reservoirs were much greater than those in 1950, the peak flows were generally only moderately higher. At the Owens-Mariposa Diversion Channel, an estimated flow of 600 cubic feet per second exceeded the design capacity of 400 cubic feet per second, and considerable flow escaped over the right levee of the bypass. At the Black Rascal-Bear Diversion Channel, flows did not exceed the design capacity of 3,000 cubic feet per second. The peak flow of Bear Creek at Merced was estimated at about 8,000 cubic feet per second, which exceeded the 1950 peak flow of about 5,000 cubic feet per second. The flood- waters of this group of creeks (Canal, Fahrens, Black Rascal, Bear, Miles, Owens, Duck, Deadman, and Dutchman Creeks) flooded about 15,300 acres of farm and pasture land. Residences on the north and west sides of the city of Merced were flooded; this residential damage was estimated at $74,000. The reservoirs on Bear, Burns, Owens, and Mariposa reduced the peak flows considerably, but the outflow of each was greater than the down- stream channel capacity, and some flooding resulted. Fahrens Creek, and Deadman and Dutchman Creeks are uncontrolled and contributed to the flooding. The damages on these creeks were estimated at $40,000 and $100,000, respectively. Damages for the entire Merced group totaled $522,000. The four Federal reser- voirs prevented damages estimated at $4,800,000, of which $4,700,000, was incurred during the December 1955 floods and $100,000 during the January 1956 floods. FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1605 Local interests completed the channel enlargement and restora- tion of channel capacities of Miles, Burns, Owens, and Mariposa Creeks in 1956 at their expense. Improvement of Bear Creek and Black Rascal Slough, below their confluence, has been deferred pending possible improvements downstream, outside the limits of the project. The four completed dams are in good condition. There are nio recreation facilities and no public use areas. There are approxi- mately 15 miles of access road maintained by the Corps. Condi- tion of the road is fair. Repairs will be required. Total costs of maintenance for Federal operation and main- tenance of the four completed reservoirs and appurtenances was $62,898 from Federal funds between July 1948 and June 30, 1957.

The area covered by this project comprises the upper watershed of Kings River, its valley alluvial fan or delta, and the lake bed known as Tulare Lake. The upper basin above the town of Piedra is rugged and mountainous. Below Piedra the river enters the relatively flat alluvial valley where the river divides, one branch known as Fresno Slough flowing north to join the San Joaquin River, and the second south to Tulare Lake, an area which in its unreclaimed state varied from a completely dry condition to a body of water some 750 square miles in extent. There is not natural outlet from this lake as it is separated from the San Joaquin Basin by a low ridge, but lake waters have es- caped over this ridge at least once since settlement of the region. Tulare Lake also receives floodwaters of Tule, Kaweah, and Kern Rivers in some years. The area below Piedra, including Tulare Lake, is known as the Kings River service area. (See U. S. Geological Survey quadrangles of the area.) Existing project. The improvement is a unit in the compre- hensive plan for flood control and other related purposes for the Sacramento-San Joaquin Basins. The project consists of a 430- foot high concrete gravity dam, including a gated overflow section with a maximum discharge capacity of 391,000 cubic feet per second, creating a reservoir with a gross storage capacity of 1,000,000 acre-feet, for flood control, irrigation, and related pur- poses. Outlet provisions for future power development are in- cluded in the dam, but Federal construction of power generating facilities is not authorized. The dam is located on Kings River, about 25 miles east of the city of Fresno, Calif., and about 4 miles upstream from the town of Piedra; construction of the dam was completed in June 1954. The improvement also includes a limited amount of channel improvement on Kings River and its distribu- taries on the valley floor about 25 miles south of Fresno. The channel improvement work will enlarge channel capacities and regulate flows in the lower branches of the Kings River. The channel improvement work has not been initiated. There are seven public use and recreation areas; one maintained by the United States Forest Service, two by concession, one by Fresno County, and three by the Corps of Engineers. Total area of Corps of Engineers maintained facilities is approximately 200 acres. The improvement will provide flood protection for about 80,000 acres of rich agricultural lands in the Kings River area and, in conjunction with the completed Isabella Reservoir on Kern River and the authorized projects on Kaweah and Tule Rivers, will pro- vide protection against floods to 260,000 acres of rich croplands in the Tulare Lake area. In addition, the project will improve the irrigation water supply with an average of 165,000 acre-feet of new water annually by retention of floodflows, and will provide a means of regulating the normal supply. The improvement to irri- gation will benefit 460,000 acres in the Kings River service area and 260,000 acres in the Tulare Lake area. FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1607 The latest approved estimate of Federal cost for new work (July 1957) is $40,900,000, of which $4,702,000 is for lands and damages including relocations and $36,198,000 for construction. Operation and maintenance of the dam and reservoir is the responsibility of the Federal Government. The average main- tenance cost during the past 4 years was $79,430. This average is lower than the latest estimated annual maintenance require- ments of $169,000 (1957) due to lack of available funds. An in- crease in funds will be required to properly maintain and operate the project for the authorized purposes. Local interests will re- imburse the United States for the conservation accomplishments of the project. The existing project was adopted by the Flood Control Act of December 22, 1944. (See H. Doc. 630, 76th Cong., 3d sess., which contains the latest published map.) Recommended modifications of project. In House Document 367, 81st Congress, 1st session, it was recommended that a power installation be authorized for construction at such time as it may be economically feasible. For an initial installation of 45,000 kilowatts, the first cost is estimated (1948) at $5,500,000, and the annual cost for maintenance and operation at $224,000. Local cooperation. The allocation to local interests for repay- ment for use of conservation storage when used, has been estab- lished in accordance with War Department Civil Appropriation Act, 1947, and published in House Document 136, 80th Congress, 1st session. The exact amount is to be agreed upon between the Bureau of Reclamation of the Department of the Interior and the local agencies concerned. Negotiations with local interests are now under way. The State of California has officially adopted the project by chapter 1514 of the Statutes of 1945, State of California. Pine Flat Reservoir is being operated for flood control purposes and for irrigation purposes under an interim agreement with Kings River Conservation District, and for storage of power water under a contract with Pacific Gas and Electric Co. Operations and results during fiscal year. Engineering and design was continued with hired labor. Cooperation was main- tained with the United States Bureau of Reclamation regarding a long-term contract for conservation operation of Pine Flat proj- ect. The following work was accomplished by hired labor: Re- moval of floatable debris; instrumentation studies; installation of a sump pump for main dam drainage; hydrological telemetering facilities and local communication net; and miscellaneous minor work. Construction of parking area and turnaround on Deer Creek Road was accomplished by hired labor and rented equip- ment. The following contracts, initiated in fiscal year 1956, were completed during the year: Bridge and weir construction and tainter gate drive shaft, inspection catwalk and miscellaneous work. Modification to the sluice stoplog gate was accomplished by contract. Maintenance: Maintenance and operation of the dam and reser- voir, service facilities, channel and river control structures, and 1608 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 public recreational facilities was accomplished by hired labor during the year. Pine Flat Reservoir was operated during the fiscal year for flood control purposes and for irrigation purposes under an interim contract with Kings River Conservation District, and for storage of power water under a contract with Pacific Gas and Electric Co. During the year, runoff from the Pine Flat drainage area was below normal. The maximum storage of the fiscal year was 937,400 acre-feet as compared to 1,000,000 acre-feet capacity and occurred on July 1, 1956. Of the 937,400 acre-feet maximum storage, 887,600 acre-feet was irrigation water and 49,800 acre-feet belonged to power interest. During the year, storage decreased to a minimum of 405,800 acre-feet on September 30, 1956 and subsequently rose to a maxi- mum for the runoff season of 898,600 acre-feet on June 20, 1957, then decreasing to 868,100 acre-feet on June 30,1957. The reser- voir pool elevation on July 1, 1956 was 940.53 feet and on June 30, 1957 was 928.14 feet. 1,516,200 acre-feet of water was released for irrigation use. The maximum mean daily release of 8,800 cubic feet per second occurred on July 1, 1956. Throughout the snowmelt season the snow pack above the reser- voir was below the 50-year average. Although this snow pack was materially increased by a late-season storm occurring May 18-21, 1957, it did not constitute a flood threat, and flood releases were not required. Total costs during the year for the project were $237,192, of which $103,469 was for new work and $133,723 for maintenance. Condition at end of fiscal year. Contruction was initiated in April 1947; the project is 95 percent complete. Construction of the main dam was initiated in January 1950, and completed in June 1954; final concrete pour was made in March 1953. The dam has been operating since February 1954 to provide the flood protection for which it was designed. Acquisition of lands.re- quired for the project is complete. Reservoir clearing, relocations of roads and utilities, construction of operational buildings, and a portion of the hydrological telemetering facilities have been completed. The dam and appurtenances are in good condition. There are 2.3 miles of project roads of which 0.8 miles are now inundated by the conservation storage pool. Minor repairs to the inundated portion will be required after drawdown. The remaining road system is in good condition. There are seven public use and re- creation areas: one maintained by the United States Forest Ser- vice, two by concession, one by Fresno County and three by the Corps. Total area of Corps maintained facilities is approximately 200 acres. Public attendance in the reservoir area for calendar year 1956 was in the order of 250,000 visitor days. Pine Flat Reservoir completely controlled the largest rain flood of the past 60 years, during December 1955, storing about 345,000 acre-feet in 7 days. and preventing about $5,000,000 damages. Toward the end of the snowmelt season, on June 30, 1956, a maxi- FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1609 mum storage of 940,500 acre-feet was reached as compared to 1,000,000 acre-feet capacity. During June 1956 spillway releases amounting to a maximum of about 12,000 cubic feet per second were made. This was the first water over the spillway and the highest stage reached since the dam was placed in operation in February 1954. During the December 1955 and January 1956 flood period, about 55,000 acre-feet of floodwaters reached the Tulare Lake area from the uncontrolled Kaweah and Tule Rivers, and during February 1956, an additional 10,000 acre-feet of water reached the lake area. The December flood contributed about 18,800 acre-feet of that in- flow, of which about 16,000 acre-feet were stored in the central "sump" area and in adjacent channels, and about 2,800 acre-feet were stored in an outlying area west of Corcoran. No inflow to the Tulare Lake area came from Kings or Kern Rivers, which were completely controlled by Pine Flat and Isabella Reservoirs, respec- tively. The principal flood damages in the Tulare Lake area were the loss of a crop of barley growing on the flooded land loss of irrigation equipment, and the erosion of levees and land. Flood damages amounted to $573,300. Without Isabella Reservoir, Kern River would have put no water in the Tulare Lake. Without Pine Flat Reservoir, Kings River would have put about 80,000 acre-feet of water in the lake. This amount of water added to the amount of water which entered the lake from Kaweah and Tule Rivers, would have flooded an addi- tional 5,700 acres in the lakebed, and would have caused additional damages of about $450,000. If the authorized Terminus Reser- voir on Kaweah River and the authorized Success Reservoir on the Tule River had been built and in operation at the time of the flood, they would have controlled the flows to nondamaging channel capacities through the project areas, but probably would have put more water into the lake than actually occurred, the exact amount depending on operating criteria to be adopted. Work remaining to be done consists of completion of work underway, installation of gages and communication facilities for operation purposes, the provision of channel improvements, and the provision of recreation facilities in connection with the overall development of the reservoir area. The radio transmitting snow gages and associated relay station are required for efficient opera- tion of the project during the snowbelt periods. These gages will be installed at remote sites at high elevations in the watershed after the snow gages already installed for this project have com- pleted one full year of satisfactory operation. The provision of channel improvements cannot be definitely scheduled; assurances of local cooperation will be required for this portion of the project prior to construction. In addition, full operation of the project during a wet year is desirable to determine the design require- ments for the channel improvements. Engineering and design is also required in connection with the above activities. Total cost of new work for the project to June 30,1957, was $38,884,236. 1610 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 Total cost of maintenance for Federal operation and mainte- nance of Pine Flat Reservoir and appurtenances was $397,147 between July 1953 and June 30, 1957. Total cost of all work for the project to June 30, 1957, was $39,281,383.

KAWEAH AND TULE RIVERS, INCLUDING TERMINUS AND SUCCESS RESERVOIRS, CALIF. Location. The area covered by this project comprises the upper watersheds of Kaweah and Tule Rivers, their valley alluvial fans and the reclaimed Tulare Lake area, their common terminus. Kaweah River, which drains an area of 630 square miles in the Sierra Nevada is formed by the junction of its north, middle, and south forks near Three Rivers, flows southwest 10 miles through low foothills and emerges on the valley floor near the town of Lemon Cove. The drainage area above the dam site is 560 square miles. At this point the river divides into two channels, the flow to each being divided equally by control weirs. The northerly channel, known as St. Johns River, flows west 23 miles and unites with Cottonwood Creek to form Cross Creek, which flows thence southwest 35 miles to Tulare Lake. The southerly channel, which continues as Kaweah River, flows southwest 4 miles and then divides into numerous distributary channels. Flows in these channels not diverted for irrigation or lost by seepage cross the delta region and unite with Tule River or Cross Creek to enter Tulare Lake. Tule River, which drains an area of 420 square miles in the Sierra Nevada, adjoining the Kaweah Basin on the south, is formed by the junction of its north and middle forks near Springville, flows southwest 13 miles and emerges on the valley floor near the city of Porterville. The drainage area above the dam site is 388 square miles. From this point the river continues west about 40 miles across the alluvial fan to Tulare Lake. Tulare Lake has been largely reclaimed for crop production and is now one of the richest crop-producing areas in the Nation. (See U. S. Geological Survey quadrangles of the area.) Existing project. The improvement provides for construction FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1611 of the Terminus and Succeess Reservoir projects including supple- mental spreading works, for flood control, irrigation, and other related purposes. The Terminus project will comprise a dam, reservoir, and spreading works. The dam will be located on Kaweah River about 20 miles east of the city of Visalia, Calif., and will be an earthfill structure 250 feet high and 2,375 feet long, with an ungated spill- way located in the left abutment of the dam, creating a reservoir of 150,000 acre-foot capacity. The spreading works will be con- structed in the valley below the reservoir and will have an infiltra- tion capacity of about 60,000 acre-feet per month. The spreading areas will range in size from about 300 acres to about 2,000 acres and the construction will consist of diversion levees, control struc- tures, channel improvement, check structures, and leveed spreading works. The project is about 3 percent complete. Success Reservoir will be located on Tule River about 5 miles east of Porterville, Calif. The main dam will be an earthfill structure 142 feet high and 3,490 feet long across the Tule River, with an auxiliary earthfill dam or dike 40 feet high and 7,650 feet long across Frazier Valley about 31/2 miles northwesterly from the main dam, and an ungated saddle spillway. It will create a reservoir of 80,000 acre-feet capacity. The project is about 14 percent complete. It is expected that the two reservoirs will receive extensive public use due to the increasing demand for additional outdoor recreational areas in that part of the State. The reservoirs are units in the comprehensive plan for flood control and other purposes for the Sacramento-San Joaquin Basin. Terminus Reservoir will provide flood protection to about 110,000 acres of agricultural land in the Kaweah River area and for the city of Visalia and adjacent urban areas. Success Reservoir will provide flood protection to about 60,000 acres of agricultural and surburban lands along the Tule River and distributaries and to the Porterville urban area. In addition, Terminus and Success Reservoirs will provide additional water for irrigation use through reductions in evaporation losses and will provide means for regu- lating the present irrigation supply. These two reservoirs in conjunction with the completed Pine Flat and Isabella Reservoirs, will help to provide adequate flood protection to 260,000 acres of croplands in the Tulare Lake area. The latest approved estimate of cost for new work (1957) is as follows: Estimated cost Project Lands and dam- Construction ages (including Total relocations) Terminus Dam and Reservoir _-----------_ . $16,058,000 $7,042,000 $23, 100,000 Success Dam and Reservoir------.. ------......... 10,368,000 4,532,000 14,900,000 Total 26,426,000 11,574,000 -..............---------...........-----------...... 38,000,000 1612 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Maintenance and operation of the reservoirs will be the responsi- bility of the Federal Government. Maintenance and operation of the channels and diversions under project conditions at Success Reservoir and the spreading works for Terminus Reservoir will be the responsibility of local interests. The existing project was adopted by the Flood Control Act of December 22, 1944. This act authorized $4,600,000 for the in- itiation and partial accomplishment of the construction of Success and Terminus Reservoirs. (See H. R. Flood Control Committee Doc. 1, 78th Cong., 2d sess., and H. Doc. 559, 78th Cong., 2d sess., which contains the latest published map.) Local cooperation. Payment, as determined by the Secretary of the Army upon the basis of continuing studies by the Bureau of Reclamation, the Department of the Army, and local organizations, is to be made to the United States by the State or other responsible agency for the conservation storage, when used. These amounts have not yet been allocated. Preliminary cost allocation studies for Success Reservoir were furnished to the four local water-users organizations in July 1956 and to the Director of the Bureau of Reclamation in September 1956. The water-users organizations passed resolutions (in August and September 1956) expressing their willingness to enter into repayment contracts. The report on preliminary cost alloca- tion studies was approved by the Chief of Engineers in March 1957. At a meeting in July 1956 of water users along the Kaweah River below the Terminus Dam site, a committee was formed to assist in the assembly of the preliminary cost allocation data. The preliminary cost allocation studies for Terminus Reservoir are about 82 percent complete and the report is scheduled for completion in fiscal year 1958. The State of California officially adopted the project by chapter 1514 of the Statutes of 1945, State of California. Local interests have agreed to maintain the spreading works portion of the Kaweah River (Terminus Reservoir) project after completion. No other local cooperation is required for construction. The latest estimate (1957) of annual cost to local interests for maintenace and operation of the spreading works for Terminus Reservoir is $23,000. In addition, local interests have constructed and are operating some of the spreading works contemplated by the project. The cost of this construction is not available. Operations and results during fiscal year. New work: a. Ter- minus Reservoir: Engineering and design, including surveys, ex- plorations, and preparation of contract plans and specifications, was continued by hired labor during the year. Engineering ser- vice contracts and rented equipment were utilized for additional surveys and field investigations. Contract engineering services were utilized for preparation of main dam plans and specifications. Preliminary cost allocation studies are about 82 percent complete. Surveys and reports in connection with land acquisition activities were accomplished by hired labor. A continuing supply contract FLOOD CONTROL--SACRAMENTO, CALIF., DISTRICT 1613 was awarded for fabrication of the outlet works slide gates and appurtenances. b. Success Reservoir: Engineering and design, including sur- veys, explorations, and preparation of contract plans and specifica- tions, was continued by hired labor during the year. Engineering service contracts and rented equipment were utilized for additional field investigations. Contract engineering services were utilized for preparation of main dam plans and specifications. Prelimi- nary cost allocation studies were completed. Land acquisition was initiated. Construction was initiated on this project with the drilling of a water well at the job site; this work was accomplished by contract and by hired labor. Fabrication of the slide gates for the outlet works was initiated by continuing contract; this work is about 84 percent complete. Contracts have been awarded to the State of California for relocation of State Highway No. 127, to Southern California Edison Co. for relocation of telephone lines around the dam and reservoir, and to county of Tulare for reloca- tion of county roads. Award of the main dam contract is pending result of court hearing for possession of construction areas. Total costs during the fiscal year for the project were $1,819,867, of which $293,964 was for Terminus Reservoir and $1,525,903 for Success Reservoir. Condition at end of fiscal year. New work: a. Terminus Reser- voir: Planning, which had been halted since fiscal year 1952 due to the Korean conflict, was resumed in fiscal year 1956 and con- tinued during fiscal year 1957. Field explorations and surveys required for definite design studies have been accomplished. De- sign memorandums for utility revisions, real estate, dam and ap- purtenances, and administration and utility buildings have been completed. Land acquisition activities have been initiated. Pre- liminary cost allocation studies are about 82 percent complete. Construction of this project will be initiated in fiscal year 1958. b. Success Reservoir: Planning for this project was also halted due to the Korean conflict and resumed in fiscal year 1956. Con- struction on this project was initiated in November 1956; the over- all project is about 14 percent complete. Design memorandums are substantially completed; preliminary cost allocation studies have been completed. Fabrication of slide gates for the outlet works is 84 percent complete; contracts have been awarded for relocation of roads and telephone lines; and land acquisition has been initiated. Construction'of the main dam is scheduled to be initiated in fiscal year 1958. Work remaining to be done includes completion of work under- way; relocation of cemeteries; reservoir clearing; construction of the main dam auxiliary dike, spillway, outlet works, roads, and operational buildings and utilities; installation of permanent operating equipment; and provision of recreational facilities. During the December 1955 and January 1956 storms, Kaweah River flooded about 126,200 acres of land. Flood runoff during December 1955 from the Kaweah River Basin was excessive in both peak and volume and exceeded the previous record of Novem- ber and December 1950. The flooded area extended from Termi- 1614 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 nus Dam site on the east to Cross Creek on the west, and from Cottonwood Creek on the north to Elk Bayou on the south, where Kaweah River and Tule River waters intermingled. Of the 120,000 acre-feet of runoff at the foothill line, only a minor amount reached the Tulare Lake area. The city of Visalia and the towns of Farmersville and Three Rivers were flooded. Over one-half of the city of Visalia was flooded in December. Nearly one-fourth of the city was reflooded in January. Nearly all roads in the area were flooded and damaged. In January, much of the area damaged by the December flood was reflooded. Flood damages for Kaweah River totaled $13,359,000, of which $1,514,000 was above the dam site and $11,845,000 below the dam site. If the authorized Terminus Reservoir had been completed and in operation, it would have controlled the floods to nondamag- ing channel capacity. The project would have prevented all flood damage along Kaweah River and its distributaries below the dam site, amounting to $11,845,000. However, under this con- dition, Kaweah River probably would have put more water into Tulare Lake than under natural conditions, thus causing some additional damage in the lake area. During the December 1955 flood, Tule River flooded about 38,000 acres of agricultural land between the foothills and Tulare Lake. The January 1956 flood inundated about 27,000 acres, including much of the same land that was flooded in December. Flood run- off from the Tule River Basin, although large in both peak and volume, was generally less than the record flows in 1950. The runoff volume of about 59,000 acre-feet at Worth Bridge, below the junction of the two forks, exceeded the 36,000 acre-feet volume of 1950. Downstream from the foothill line, there were numerous levee breaks. Of the 39,000 acre-feet of runoff at the foothill line, only a minor amount reached the Tulare Lake area. Along streams in the foothill area above Success dam site, damages occurred to roads and bridges, a small dam on North Fork, a Pacific Gas and Electric Co. powerplant intake structure, canal headworks, and to summer cottages at Doyle Springs. In the town of Springville, damages were held to a minimum by the heavy masonry walls built along the river bank, but bridge ap- proaches and parts of the roads were washed out. Between Suc- ceess dam site and the Friant-Kern Canal crossing, there was severe erosion along the river, but only minor flooding. The city of Porterville and its suburbs were not flooded. Most of the canal diversions and headworks on the river were washed out. Below the Friant-Kern Canal crossing, there was erosion in the flooded area along the stream channels, accompanied by drifts of sand, silt, and debris. Homes, farm buildings and equipment, crops, highways, and bridges in the flooded area were damaged. Flood damages for Tule River totaled $1,925,000, of which $197,000 was above the dam site and $1,728,000 below the dam site. If the authorized Success Reservoir had been completed and in operation it would have completely controlled the December 1955 and January 1956 floods to nondamaging channel capacity. The project would have prevented all of the flood damage which FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1615 occurred along Tule River and its distributaries below the dam site, estimated at $1,728,000. However, under this condition, Tule River probably would have put more water into Tulare Lake under natural conditions, thus causing some additional damage in the lake area. Total, cost of new work to June 30, 1957, was $2,729,528, of which $679,417 was for Terminus Reservoir and $2,050,106 for Success Reservoir.

ISABELLA RESERVOIR, KERN RIVER, CALIF. Location. The area covered by this project comprises the upper watershed of Kern River, its valley alluvial fan (which includes the Buena Vista Lake area and a large portion of that part of the San Joaquin Valley floor south of Tulare Lake), and the Tulare Lake area. Kern River is the most southerly of the major streams flowing into the San Joaquin Valley and drains an area of some 2,400 square miles in the Sierra Nevada. North Fork and South Fork, headwaters of Kern River, have their sources in the high Sierra Nevada, flow south 83 and 82 miles, respectively, and join near the town of Isabella to form Kern River, which flows south- west 72 'miles past the city of Bakersfield to a point in the valley trough just north of Buena Vista Lake. River flows at this point are either diverted into the Buena Vista Lake Basin for temporary storage or are carried northwest along the trough of the valley toward Tulare Lake by improved flood and irrigation channels. Under normal conditions of runoff the flow of Kern River below Bakersfield is gradually dissipated by irrigation diversions so that Kern River water reaches Tulare Lake only during large floods. (See U. S. Geological Survey quadrangles of the area.) Existing project. The improvement is a unit in the comprehen- sive plan for flood control and other related purposes for the Sacramento-San Joaquin Basins. The project consists of a 185- foot high earthfill structure, an ungated concrete spillway in the left abutment with a discharge capacity of 53,000 cubic feet per second, and a 100-foot high earthfill auxilary dam, creating a reservoir with a gross storage capacity of 570,000 acre-feet, for flood control, irrigation, and related purposes. Outlet facilities 1616 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 for the Borel Power Canal are included in the auxiliary dam. The dam is located about 50 miles northeast of the city of Bakersfield, Calif., near the confluence of the north and south forks of Kern River; the auxiliary dam is about one-half mile east of the main dam. Construction of the dam was completed in April 1953. Sinrce April 1954, when conservation storage began in Isabella Reservoir, the public has made increasing use of the reservoir area for recreational purposes. The Corps of Engineers has provided an observation point with paved parking area in the vicinity of the main dam. Kern County has developed four campground areas. In addition, there are two boating concessions. The improvement provides flood protection for about 350,000 acres of agricultural land and oil fields in the Kern River area and for the city of Bakersfield. In conjunction with the com- pleted Pine Flat Reservoir on Kings River and the authorized projects on Kaweah and Tule Rivers, it will provide flood protec- tion to 260,000 acres of cropland in the Tulare Lake area. The project also provides an improvement in the average annual irri- gation water supply amounting to about 50,000 acre-feet of new water, through reduction in evaporation losses, and provides means for regulating the irrigation supply. No power facilities were provided in the authorized construction, but existing downstream plants benefit incidentally from reservoir regulation. The latest approved estimate of Federal cost for new work (1956) is $21,030,000, of which $11,456,300 is for lands and damages, including relocations and $9,573,700 for construction. Operation and maintenance of the dam and reservoir is the re- sponsibility of the Federal Government. The average annual maintenance cost during the 4 years of operation was $38,215. This is lower than the estimated (1957) annual maintenance cost of $80,000 due to lack of funds. An increase in funds will be required to properly maintain and operate the project for the authorized purposes. Local interests will reimburse the United States for the conservation accomplishments of the project- The existing project was adopted by the Flood Control Act of December 22, 1944. (See H. Doc. 513, 78th Cong., 2d sess., which contains the latest published map.) Local cooperation. Payment, as determined by the Secretary of the Army upon the basis of continuing studies by the Bureau of Reclamation, the Department of the Army, and local organizations, is to be made to the United States by the State or other responsible agency for the conservation storage when used. Local interests have stated that they will meet these requirements. Studies to determine the amount of the payment have been made, and nego- tiations have been initiated on the repayment contract. The reser- voir is being operated for flood-control purposes and for irrigation purposes under an interim contract with North Kern Water Stor- age District, Buena Vista Water Storage District, and Tulare Lake Basin Water Storage District. The State of California has offi- cially adopted the project by chapter 1514 of the Statutes of 1945, State of California. FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 1617 Operations and results during fiscal year. New work: Engin- eering and design activities were continued by hired labor. In addition, engineering and economic studies of the Kernville- Weldon Road were accomplished by contract. Settlement of out- standing claims under land acquisition activities was accomplished. An agreement was reached with the county of Kern for settlement of pending claims in connection with Kernville-Weldon and Kern- ville-Fairview Road relocations. Drainage for Borel Canal was accomplished by contract and additional hydrologic telemetering facilities were installed by hired labor. Trash rack, rake, and gate seal modfications, initiated in fiscal year 1956 by contract, were completed. Purchase and installation of radio active snow gages and relay station was initiated by continuing contract. Maintenance: Maintenance and operation of the dam and reser- voir service facilities and public recreational facilities was accom- plished by hired labor. In addition, hired labor was utilized during the fiscal year for condition and operation inspections and for condition surveys, including maintenance of gages and gage readings. Isabella Reservoir was operated during the fiscal year for flood- control purposes and for irrigation purposes under an interim contract with North Kern Water Storage District, Buena Vista Water Storage District, and Tulare Lake Basin Water Storage District. Runoff from the main Kern River during the year was below normal. The maximum storage during the fiscal year was 283,000 acre-feet as compared to 570,000 acre-feet reservoir capa- city and occurred on July 1, 1956. Of the 283,000 acre-feet maxi- mum storage, 253,900 acre-feet was irrigation water and 29,100 acre-feet was stored for recreation. During the year, storage decreased to a minimum of 123,900 acre-feet on April 16, 1957 and subsequently rose to a maximum for the runoff season of 184,000 acre-feet on June 20, 1957, then decreasing to 181,200 acre-feet on June 30, 1957. The reservoir pool elevation on July 1, 1956 was 2575.80 feet and on June 30, 1957 was 2561.38 feet. 594,500 acre-feet of water was released for irrigation use. Of this, 323,100 acre-feet was released through Borel Canal and 271,400 acre-feet was released through the Kern River outlets. The maximum mean daily total release of 2,230 cubic feet per second occurred on July 1, 1956. Throughout the snowmelt season the snow pack above the reser- voir was below the 50-year average. Although the snow pack was materially increased by a late-season storm occurring May 18-20, 1957, it did not constitute a flood threat, and flood releases were not required. Total costs during the fiscal year for the project were $431,275, of which $374,676 was for new work and $51,259 for maintenance. Condition at end of fiscal year. Construction was initiated in March 1948; the project is 99 percent complete. Construction of the main dam and Borel Canal outlet works and appurtenances and completion of the auxiliary dam was completed in April 1953. 1618 REPORT OF THE CHIEF OF ENGINEERS U. S. At1MY, 1957 The project is operating to provide the flood protection and con- servation benefits for which it was designed. Other major fea- tures completed include; Acquisition of lands required for the project except for legal proceedings; relocations of roads and utilities; construction of operational buildings; alteration of Borel Canal facilities; relocation of United States Forest Service facilities; and reservoir clearing. Runoff from the main Kern River, although large in both volume and peak, was generally less in December 1955 than in 1950. Isabella Reservoir completely controlled the December floodflows of Kern River to nondamaging releases, and no flooding occurred below the reservoir. Above Isabella Reservoir, roads along the river were damaged by erosion, the diversion dam to Borel powerplant canal was washed out, the Kern River Power- plant No. 3 suffered damage to its intake works, the fish hatchery was flooded and its stock of fish washed away, and the Forest Service Camp and the Kernville picnic grounds were flooded. Total damages caused by the Kern River were $136,000. Esti- mated damages prevented by the reservoir were about $1,000,000. In 1950, before the project was built, floods caused damages below the dam site of about $1,600,000. The dam and appurtenaces are in good condition. Public at- tendance in the reservoir area for calendar year 1956 was in the order of 475,000 visitor-days, with a peak day of 12,000 visitors. Items remaining to complete the project consist of completion of relocation of power and communication lines; construction of fishway for Borel Canal intake :modification of Borel Canal structure and automatic gate controls; additional recreational facilities; installation of radio transmitting snow gages and as- sociated relay stations (hydrologic facilities required for the effi- cient operation of the project during snowmelt periods); and completion of legal proceedings for acquisitions of lands. Date of completion for the relocations work depends upon imminence of inundation of existing facilities. The gages and relay stations will be installed at remote sites at high elevations in the watershed. Total cost of new work for the project to June 30, 1957, was $21,149,646.

SALT LAKE CITY, JORDAN RIVER, UTAH Location. The Jordan River has its source in Utah Lake, north central Utah, flows northward through a mountain gap for 9 miles, then continues north for 51 miles to enter Great Salt Lake about 15 miles north of Salt Lake City. The flood-control im- provements are located in and adjacent to Salt Lake City. Existing project. The project provides for control of floods from the Jordan River at Salt Lake City by diverting to the Great Salt Lake, via Surplus Canal, the floodflows in excess of the exist- ing river channel capacity within the city. The plan of improve- ment involves (a) increasing the channel capacity of Jordan River between Mill Creek and the head of the Surplus Canal by channel excavation and levee construction; (b) modifying the existing control structures at the head of Surplus Canal; (c) enlarging Surplus Canal by channel excavation and levee construction from its head downstream to the existing diversion structure leading to Goggin Drain, an existing secondary distributory to Great Salt Lake; (d) reconstructing or modifying five railroad and three street bridges; and (e) modifying an obstructive irrigation di- version and other utilities. Except for the alteration of railroad bridges and the modification of the existing structures at the junction of Jordan River and Surplus Canal, local interests will provide the necessary alteration and construction of structures and utilities. Construction has not been initiated. The project will protect the westerly part of Salt Lake City and surburban lands west of the city from Jordan River floods. The area to be benefited includes about 5,800 acres of urban and subur- ban residential, industrial, and Commercial property. Protection also will be provided to segments of United States Highways Nos. 40 and 50, and four railroads and the municipal airport, irrigation facilities, and other utilities. The latest approved estimate of Federal cost for new work (1957) is $1,720,000, of which $236,000 is for railroad bridge alterations and extensions and $1,484,000 for construction. The existing project was authorized by the Flood Control Act approved July 24, 1946. (See H. Doec. 562, 79th Cong., 2d sess., which contains the latest map.) Local cooperation. Local interests are required, before work is undertaken, to give assurances satisfactory to the Secretary of the Army, that they will (a) provide without cost to the United States all lands, easements, and rights-of-way necessary: for the construction of the project works, and in addition, bear the ex- pense of all necessary alterations and construction of highway facilities, irrigation works, and other utilities except railroad bridges and except control structures at the junction of Jordan River and the Surplus Canal; (b) hold and save the United States free from damages due to the construction works; and (c) main- 1620 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 tain and operate all the works after completion in accordance with regulations prescribed by the Secretary of the Army. The Board of Commissioners, Salt Lake County, representing local interests, have expressed their willingness to fulfill the requirements of local cooperation. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $410,000 (1957). The estimated annual cost of maintenance and operation, including replacements, is $36,000 (1957). Operations and results during fiscal year. Engineering and design was continued by hired labor.

S. ARMY, 1957 December 1955 storm, ground conditions continued to be critically wet throughout the Sacramento-San Joaquin River Basins, and a series of moderate size storms, during January and February 1956, caused repeated rises on various streams. As a result of the intense rainstorms and the exceptionally large streamflows which occurred throughout the Sacramento-San Joaquin Valley, the Tulare Basin, and the western Nevada areas, virtually every major stream overflowed its banks at some point, and many levees were broken. Rights-of-way and assurances relative to holding the United States free from damages and future maintenance of project work were received prior to initiation of emergency works. The following activities were conducted under authority of Public Law 99, 84th Congress, approved June 28, 1955: Advance preparation for flood emergencies; preliminary investigations of required repairs and restoration; preparation of post flood reports; and supervision and administration of rehabiliation work by Sacramento District. emergency repair and restoration of navigation and flood- control works were continued and accomplished under the provi- sions of applicable authority at the following locations.

SCHEDULING OF FLOOD-CONTROL OPERATIONS The reservoir regulation manual for Folsom Reservoir was com- pleted. Summaries of monthly operations at Folsom, Friant, Shasta, Don Pedro, Cherry Valley, Hetch Hetchy, and Big Dry Reservoirs were prepared and distributed. Navigation-flow requirements were analyzed to determine operational criteria for Shasta Reservoir. Further analysis was deferred until the navigational needs are more imminent. Data were assembled on weather, river stages and flows, and tidal stages in the Sacramento and San Joaquin River Basins. The cost of this work during the fiscal year 1957 was $2,765. Total cost of this work to June 30, 1957, was $32,480.

EXAMINATIONS AND SURVEYS Work performed under this category includes all investigations of authorized navigation and flood-control preliminary examina- tion, survey, and review studies for the purpose of determining the advisability of recommending projects for construction which are economically feasible within specific water basins. The ra- pidly developing economy of the Nation requires that the Federal Government keep its program of authorized public works coordi- nated with current and prospective needs for rivers and harbors improvements and flood-control and related purposes. The scope and extent of the navigation, flood-control, and water resources problems involved affect national and local economy and security. ,During fiscal year 1957, work under this activity included con- tinuation of 10 investigations, initiation of one investigaton, and completion of one investigation. Total costs during fiscal year 1957 were $294,457. The balance unexpended on June 30, 1957, $19,956, and an antic- ipated allotment for fiscal year 1958 of $218,800, a total of $238,756, will be applied during fiscal year 1958 to payment of expenses to be incurred for continuation of investigations. 23. RESEARCH AND DEVELOPMENT Hydrologic studies conducted under this activity are essential basic activities pertaining to navigation, flood control, and related programs, which are essential to the proper evaluation of water resources of river basins. These studies provide a background of information and experience which is subsequently utilized in the design, construction, and operation of water-control struc- tures; the studies are not properly chargeable to authorized projects or reports. 1628 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 Civil-works investigations designed to assist in the solution of unsolved or incompletely solved problems associated with design, construction and operation, and maintenance of civil-works proj- ects. These investigations are engineering problems which are encountered over a wide segment of the area of the civil functions performed by the Corps of Engineers. The solutions are dissemi- nated to permit optimum utilization of the results throughout the Corps of Engineers. Miscellaneous hydrologic studies in connection with the collec- tion and study of basic data were conducted to the extent permitted by the very limited funds available for fiscal year 1957. Stream- flow data and recording rain gage data were obtained from the operations of general coverage stations in the noncooperative Corps of Engineers streamgaging program and independent general coverage rain gages operated by Sacramento District which could not be assigned to authorized project or examination and survey investigations. Analysis of current flood potential on all principal streams of the Sacramento District was accomplished from current runoff, snow cover, and soil-moisture data. Aerial reconnaissance surveys were conducted of the snow fields in the Cascade-Sierra Nevada area for progress of snow-melt runoff. In addition, a flood reporting network was maintained throughout the district in cooperation with United States Forest Service, United States Weather Bureau, United States Geological Survey, State of California, and local interests. Special sedimentation surveys were made of principal Corps reservoirs to determine sediment accumulation that occurred during the major 1955 rain- flood. The above studies provided for partial assembly and analy- sis of basic data covering the Sacramento-San Joaquin Basins and for use in reviewing the regulations for Shasta and Friant Reservoirs, operated by the Bureau of Reclamation. The costs during the fiscal year for research and development were $22,669, comprising $3,289 for hydrologic studies and $19,380 for civil-works investigations. The balance unextended at the end of the fiscal year, amounting to $1,178, plus an anticipated allotment of $20,200, a total of $21,378, will be applied to hydrologic studies and civil-works in- vestigations planned for fiscal year 1958.

This project is located on Columbia River at the head of the pool behind Bonneville Damn, approximately 193 miles above the mouth of the river and 90 miles east of Portland, Oregon. Existing project. This project provides for a dam, powerplant, navigation lock and appurtenant facilities. The improvement will provide for navigation and hydroelectric power generation. The dam is designed for a normal pool at elevation 160 mean sea level. The normal pool will create a reservoir extending upstream about 25 miles providing slackwater to the John Day dam site. The total length of The Dalles Dam is 8,700 feet and consists of a rock, gravel, and sand river closure section from the Oregon shore connecting to a non-overflow section which in turn joins the power- house, then concrete non-overflow sections connecting the spill- sway with the powerhouse and the spillway with the navigation lock located at the right abutment on the Washington shore. Fish passing facilities including two ladders are provided. The power- house is constructed for 14 units which are to be installed initially and substructure constructed for 8 additional units, an ultimate total of 22 units. Initial installation, including 2-13,500 kw fish- water units, will be 1,119,000 kilowatts. The structures are founded on Columbia River basalt. The principal data concerning the lock, spillway and powerhouse are shown in the following table.

The estimate of cost for new work (1957) is $255,000,000 of which $56,000,000 is for lands and damages including relocations, and $199,000,000 for construction. The existing project was authorized by the River and Harbor and Flood Control Act approved May 17, 1950, House Document 531, 81st Congress, 2d session. Local cooperation. None required. Operationsand results during fiscal year. Construction of the project continued satisfactorily throughout the fiscal year with all major phases of work accomplished approximately as scheduled. Relocation of 23 miles of U.P.R.R. on the Oregon shore and 14 miles of Spokane Portland and Seattle track on the Washington shore was completed and both relocated lines placed in full opera- tion. On the Oregon shore all highway and highway bridge work was completed except for placing of the asphaltic concrete pave- ment to be completed by the Oregon State Highway Commission under a relocation agreement. Under the phase II continuing contract, which includes the powerhouse superstructure for main units 1-14, and west non- overflow dam, work continued ahead of schedule. The nonoverflow dam was completed. Installation of turbine embedded parts and concrete placing for the main generating units were in progress at the end of the year. Installation of mechanical and electrical equipment in the power- ouse progressed satisfactorily. Station service units were activated. Fishwater supply generator unit No. 1 was placed on the line May 13, 1957. Fishwater unit No. 2 was on the line June 3, 1957. Installation of piping, conduit, electrical work, and painting were continued. Construction of the river closure dam was completed, and on 1632 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 March 9, 1957, the pool behind the dam was raised to approximate elevation 130 m.s.l. On March 16 the pool was raised to minimum pool elevation of 155 m.s.l. and the completed navigation lock was opened to river traffic on March 17, 1957. Raising to normal pool elevation of 160 m.s.l. will be accomplished July 15, 1957, when the new lift span of the reconstructed Oregon Trunk Railway bridge at Celilo is placed in full operation. Fabrication, delivery, and installation of main unit turbines, generators, and control equipment, are progressing with no delays forseen in meeting scheduled completion dates. Total costs for the fiscal year were $54,513,424, of which $54,410,166 was for new work and $103,258 for maintenance. Power Generation: A total of 15,482,000 kilowatt-hours of electric power were generated, of which 14,486,000 kilowatt-hours were delivered to Bonneville Power Administration, the marketing agency, for disposition. Condition at end of fiscal year. Construction of the project initiated February 1952 is 81 percent complete as a whole. Relocation work is complete except for work being performed by the operating companies under the relocation agreements. Both the Union Pacific Railroad and Spokane Portland and Seattle Railway relocated lines are in full operation. The spillway dam, nonoverflow dams, powerhouse substructure, navigation lock, and fish passing facilities are complete. Fishwater supply generators are in operation and main genera- tor units No. 1 and 2 are scheduled to be placed on the line November 1957. Construction of the powerhouse superstructure and appurtenant work is 91 percent complete and is scheduled to be 100 percent complete August 1958.

The lower end of the canal is about 4 miles and the lower end of the Threemile Rapids about 1/2 miles above The Dalles, Oreg. The normal pool level at the lower end of the canal has an eleva- tion of 72.5 feet above mean sea level and the highest flood 114.2 feet above mean sea level. At the upper end of the canal the normal freshets are about 18 feet and the maximum rise 33 feet. The canal was designed to operate to a stage of 18 feet at the upper pool and is then "drowned out" until the river recedes to a stage of 18 feet. The actual cost for new work was $4,669,092.23, exclusive of amount expended on previous projects. The average annual maintenance cost during the past 5 years was $87,490. The existing project was adopted by the River and Harbor Act of 1March 3, 1905 (Annual Report, 1904, p. 3475). Operation and care of the canal were included in the project July 1, 1935, under the provisions of the Permanent Appropriations Repeal Act approved June 26, 1934. For latest published map see Annual Report for 1915, page 3380. Local cooperation. Fully complied with. Terminal facilities. None. Operations and results during fiscal year. The canal and locks were in complete operation until January 2, 1957, when the canal was closed to through traffic because of the construction of The 1634 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Dalles Dam river closure section at Big Eddy. Pumping of petroleum products through the closure section was accomplished until March 1, 1957, when the canal and locks were closed to all traffic and dismantling of lock gates, machinery, and other salvage- able items was accomplished prior to the "drowning out" of the project by the raising of The Dalles Dam pool on March 9, 1957. During the fiscal year a total of 17,550 cubic yards of material was dredged from the canal and turning basin. The cost of maintenance (operation and care) for the fiscal year was $31,596. Condition at end of fiscal year. Construction of the project was completed in 1919. From that year to March 1, 1957, the canal and locks were in continuous operation except for temporary closures, required for maintenance and improvement, modification, and repair. On March 9, 1957, the project was drowned out by the raising of the pool behind The Dalles Dam multiple purpose project. Total costs excluding those under a previous project have been $6,979,831 of which $4,669,092 was for new work, $5,445 for main- tenance and $2,305,294 for operation and care. In addition, the sum of $525,267 was expended between May 5, 1915, and June 30, 1935, on operation and care of the project, under provisions of the permanent indefinite appropriation for such purposes.

COLUMBIA RIVER AT BONNEVILLE, OREG. Location. This project is located on Columbia River, 42 miles east of Portland, Oreg., about 144 miles above the mouth of the river. For description of Columbia River see page 1657. Existing project. This project provides for a dam, powerplant, and lock, for power and navigation. The spillway dam extends across the main channel from the Washington shore to Bradford Island, which divides the river at this point. The overflow crest at 24 feet above mean sea level is surmounted by 18 vertical-lift steel gates placed between piers which extend to elevation 99 feet where a service roadway permits the operation of two 350-ton gantry cranes for regulating the gates. The powerhouse extend- ing across Bradford Slough to the Oregon shore has an installa- tion of 10 units, consisting of two units of 43,200 kilowatts each and eight units of 54,000 kilowatts each, totaling 518,400 kilowatts. The ordinary and extreme fluctuations of the river at the lower RIVERS AND HARBORS-PORTLAND, OREG., DISTRICT 1635 lock gate are about 21 and 47 feet, respectively. The project includes fish ladders and locks to serve both the main channel and the Bradford Slough channel. The lock and powerhouse are founded on andesite, and the main dam rests upon solidified sedimentary rock of volcanic origin. The pool created by the dam provides a navigable channel with a depth of 30 feet and over between Bonneville and Big Eddy, a distance of 47 miles. The principal data concerning the ship lock and spillway dam are shown in the following table: Ship Lock Dimensions: Clear width of chamber--- 76 feet.

The River and Harbor Act approved March 2, 1945, provides in connection with the Camas-Washougal turning basin that local interests furnish assurances that they will con- struct a suitable freight terminal, open to all on equal terms, and bear additional cost of disposing of dredged material behind bulkheads provided by them; and provides that no dredging will be performed by the United States within 50 feet of the proposed dock. Total estimated costs for all requirements of local coopera- tion under terms of the project authorization, amount to $125,000 (1957). The act of July 24, 1946, provides that for improvements at Hood River, Oreg., and at Bingen, Wash., local interests furnish free of cost to the United States all necessary rights-of-way, agree to maintain depths in the basins, and to construct, operate, and maintain necessary mooring facilities and public wharf available to all on equal terms. Total estimated costs for all requirements of local cooperation under the terms of the project authorization, amount to $59,500 for Hood River boat basin and $213,000 for Bingen barge canal (1957). Assurances of local cooperation for The Dalles Harbor were approved by the Secretary of the Army October 5, 1948. Terminal facilities. At Vancouver, Wash., immediately up- stream from the highway bridge, are a private sand and gravel wharf, a United States Coast Guard dock, a private towboat moorage equipped with marine railway, and facilities for transfer of bulk petroleum from river barges. (For further details con- cerning facilities at Vancouver see Port Series No. 33, Corps of Engineers, published in 1953.) At North Portland, Oreg., on the south bank of the river, about 1.7 miles upstream from the highway bridge, is a wharf with a 110-ton crane used for transfer of cargo from truck to water. At Camas, Wash., about 13.5 miles upstream from Vancouver, are located a private wharf used for transfer of paper mill supplies and paper to and from barges, and also facilities for RIVERS AND HARBORS-PORTLAND, OREG., DISTRICT 1641 discharging bulk oils from barges. The port of Camas-Washougal has a wharf 528 feet in length at Washougal, Wash., which will be available for oceangoing vessels when a suitable channel is provided. At the port of The Dalles (mile 44 above Bonneville) there is a municipal wharf 125 by 1,100 feet for use by both ocean vessels and river boats. There are two 1-story timber and corrugated- iron warehouses, each 94 by 461 feet, on this wharf with rail connections. There is also a municipal oil terminal consisting of a concrete and timber wharf 27 by 193 feet, located about a mile below the main wharf. There are private storage tanks with a total capacity of 2,300,000 gallons located near this ter- minal for handling petroleum products. Storage tanks have rail, truck, and water connections. A private elevator with a capacity of 40,000 bushels and a public elevator of 868,000-bushel capacity for handling bulk grain to river craft are also located at The Dalles. The public elevator has rail, truck, and water connec- tions. There is a privately owned rail connection about three- fourths mile below the municipal wharf where certain types of cargo may be handled between railroad cars and river boats or barges by means of a derrick of up to 22-ton capacity. At numerous locations over the entire waterway are log rollways for transfer of logs to water from trucks. The existing facilities are considered adequate for present commerce. Operations and results during fiscal year. New work: A de- sign memorandum was completed and preparation of contract plans and specifications in progress covering construction of a channel 10 feet deep and 300 feet wide at the upper entrance to Oregon Slough, Oreg. Maintenance: The repair of existing pile dikes and construction of dolphins halted in April 1956 because of high waters were resumed in September and all work completed November 1956. Dredging of the moorage area below the Bonneville Dam naviga- tion lock was accomplished February-March 1957 with a total of 7,921 cubic yards of material removed by contract at a cost of $8,789. A total of 258,450 cubic yards of material were removed from the navigation channel by Government plant at a cost of $59,857. Hydrographic surveys were made at a cost of $23,173. Total costs for the fiscal year were $102,772, of which $792 was for new work and $101,980 for maintenance. Condition at end of fiscal year. The existing project is 44 per- cent complete. Dredging of the main channel between Vancouver and Bonneville was completed to project dimensions of 27 feet deep and 300 feet wide in 1949. Some work, consisting of the improvement of the lower entrance to Bonneville canal, remains to be accomplished. This channel, at the present time, is used principally for barge transportation and log towing and is main- tained to a depth of 15 feet. Depths of 20 feet or more are avail- able between Bonneville and The Dalles. Construction of The Dalles Harbor was completed in 1949. 1642 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 No construction work has been done on the 27-foot channel be- tween Bonneville and The Dalles, the channel at the upper entrance to Oregon Slough, the Camas-Washougal turning basin, the Hood River boat basin, or the Bingen channels. Plans and specifications are being prepared for channel dredging at Oregon Slough early in fiscal year 1958. Total costs have been $3,978,592, of which $3,075,305 was for new work and $903,287 for maintenance.

This provides for improvement of Willam- ette River between Portland (14 miles above the mouth) and Oregon City (mile 26) by a channel 8 feet deep at low water, 200 feet wide below Cedar Island and 150 feet wide thence to Oregon City; for such channel improvement and contraction works as may be necessary to secure with streamflow regulation, controlling depths of 6 feet at low water and of no prescribed width, from Oregon City to the mouth of Santiam River (mile 108.5), 5 feet from that point to Albany (mile 120), 2.5 to 3.5 feet deep from Albany to Corvallis (mile 132), and for a channel 2.0 to 2.5 feet deep from Corvallis to Eugene (mile 185) ; and for RIVERS AND HARBORS-PORTLAND, OREG., DISTRICT 1643 necessary snagging between Corvallis and Harrisburg (mile 163). The project also provides for a channel in Yamhill River 4 feet deep at low water and 60 feet wide from its mouth to McMinnville (18 miles) secured by means of a lock and dam near Lafayette and by the removal of obstructions. The section of Willamette River in the vicinity of Willamette Falls at Oregon City is covered by the project described on page 1645 of this report. Operation of Yamhill Lock was discontinued February 7, 1954, due to lack of use by commercial traffic. For the Willamette River below the falls at Oregon City ordinary fluctuation of stage of water is 15 feet and the extreme fluctuation due to flood conditions 35 to 50 feet. Above Oregon City the ordinary fluctuation is 12 to 20 feet and the extreme is 20 to 27 feet. For the Yamhill River the ordinary fluctuation is 35 feet and the extreme 48 feet. Tidal changes vary from about 21/2 feet at the mouth of the Willamette to zero, 26 miles above the mouth. The approved estimate (1957) of cost for new work is $2,780,)00. The average annual maintenance cost for the past 5 years is $408,487.

Local cooperation. None required. Terminal facilities. Between Portland and Willamette Falls the terminal facilities consist of privately owned mill wharves, sand and gravel wharves, and oil-receiving stations. Above the falls there are privately owned landings including a facility at pulp siding (3 miles above the falls) with rail and water connec- tions for shipment of clay and receipt of paper mill products, by barge. About 5 miles downstream from Albany there is a tank farm of 1,367,100-gallon capacity with truck and water connec- tion which receives petroleum by barge from Portland. At numerous locations over the entire waterway there are log roll- ways with water and rail or truck connections, to facilitate the movement of logs to mills in the lower Columbia and Willamette Rivers. These facilities are considered adequate for existing commerce. 1644 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Operations and results during fiscal year. Maintenance channel dredging above Oregon City was accomplished during the fiscal year with the removal of a total of 914,280 cubic yards of material; 791,400 by Government plant and 122,880 cubic yards by contract, respectively. This dredging with removal of snags maintained sufficient depths for the requirements of navigation. The construction of channel stabilization works at Scatter Bar, about 6.5 miles downstream from Corvallis, was accomplished by contract. Releases of stored water from Fern Ridge, Cottage Grove, Detroit, Lookout Point, and Dorena Reservoirs aided materially during low water periods in providing sufficient depths for existing traffic. For detailed information on reservoir releases see pages covering those reservoirs under "Flood Control Projects." The various items of maintenance and costs incurred were as follows: Dredging, Government plant______------- ---- ____ $309, 331 Dredging, contract plant--------------------------------- 61, 286 Hydrographic surveys----------------------------------40, 298 Channel stabilization works __________------____ - 51, 500 Total costs for the fiscal year were $494,363, all for maintenance. Condition at end of fiscal year. The existing project is approxi- mately 40 percent complete. The 8-foot channel between Portland and Oregon City and a 2.5 to 3.5-foot channel between Oregon City and Albany were completed in 1939. The 2.5 to 3.5-foot channel between Albany and Corvallis was completed in 1945. The remaining work required to complete the project consists of the construction of such contraction works and channel improve- ments as may be necessary, with stream-flow regulation, to secure controlling depths of 6 feet at low water from Oregon City to the mouth of Santiam River, and 5 feet from that point to Albany. Controlling depths at low water are 8 feet from Portland to Oregon City, and 3.5 feet from Oregon City to Corvallis. In Yamhill River, the controlling depth is 4 feet from the mouth to Yamhill Lock. Traffic consists of towboats, log rafts, launches, and dredges. Between Oregon City and pulp siding (about 3 miles) and between Oregon City and Portland, barges are used in the transportation of paper and wood-pulp products. Petroleum products are also barged between Portland and Albany. Due to lack of use by commercial traffic for which the facilities were provided, operation of Yamhill Lock was discontinued February 7, 1954. Total costs under the existing project, from Federal funds, have been $8,818,776, of which $615,170 was for new work; $8,059,478 for maintenance; and $144,128 for operation and care. In addi- tion, the sum of $106,433 was expended between September 24, 1900, and June 30, 1935, on operation and care of the improvement under the provisions of the permanent indefinite appropriations for such purposes. The additional sums of $7,500 were expended from contributed funds for maintenance and $484,900 from Emergency Relief Administration funds for new work.

The locks and dam covered by this project are located at Willamette Falls, a rocky reef in the Willamette River at Oregon City, Oreg., about 26 miles above the mouth of the river. Existing project. This provides for the construction of a new single-lift main lock and a guard lock each with clear dimensions of 56 feet by 400 feet and a minimum depth over the sills of 91/2 feet, to replace the authorized existing facilities which were pro- vided for by the purchase, rehabilitation, and deepening to 6 feet at low water of the existing canal and locks and the separation of the canal from the waterpower intake by construction of a concrete division wall. The total length of the existing canal and locks is about 3,500 feet. The following table shows the principal features of the existing canal and locks at Willamette Falls: 1 Usable lock dimensions __-.-- Series of 4 locks, each 1752 by 37 feet.

' The dam is owned by private parties. The ordinary fluctuation of the stage of water above the locks is 12 feet, and the extreme, due to flood conditions, 20 feet. Below the locks the ordinary fluctuation is 15 feet and the extreme 50 feet. The estimated Federal cost (1957) is $10,300,000. The average annual maintenance cost for the past 5 years is $173,340. Local cooperation. Fully complied with. Terminal facilities. The Crown Willamette Paper Co. has a 1646 REPORT OF THE CHIEF OF ENGINEERS, U. S.

Operationsduring fiscal year. The canal and locks were in con- tinuous operation throughout the fiscal year, except for temporary closures required for maintenance operations. Periods of closure were: April 11, 7:00 a. m. to 1:30 p. m. for repair of gate No. 4, and from 11:00 p. m. to 7:00 a. m. April 30 to May 3, 1957, for dredging and removal of debris from the locks, canal, and ap- proaches. Ordinary maintenance of the grounds and facilities was accomplished as required. Total costs during the fiscal year were $150,411, for operation and maintenance. Condition at end of fiscal year. The existing canal and locks originally constructed by private interests in 1873 were purchased by the United States in April 1915 for $375,000. The final report on the purchase and rehabilitation of the canal and locks is con- tained in the Annual Report for 1923, when the project was re- ported 98 percent complete. No further work on that phase of the existing project has been necessary. The controlling depth is 6 feet at low water on the miter sill of the upper lock. ,The existing locks and grounds are in fair condition and are in continuous operation except when flooded out by high water or undergoing repair. Thefacilities are obsolete and inadequate for existing traffic. No construction work has been done on the lock and guard lock, which was authorized to replace the existing facilities, by the Flood Control Act of June 28, 1939, and the River and Harbor Act of March 2, 1945. Plans and specifications for the work have been essentially completed, but will require review and revision. Total costs have been $3,170,940, of which $520,005 was for new work ($377,122 for purchase and rehabilitation of existing lock and canal and $3,883 for new lock from River and Harbor funds and $139,000 for new lock from Flood Control funds), and $2,650,935 for maintenance (operation and care) from River and Harbor funds. In addition $300,000 was expended from contributed funds for new work on existing canal and lock and $452,110 was expended between April 16, 1915, and June 30, 1935, on the operation and care of the improvement under the provisions of the permanent indefinite appropriations for such purposes.

COLUMBIA AND LOWER WILLAMETTE RIVERS BELOW VANCOUVER, WASH., AND PORTLAND, OREG. Location. This project embraces 1031/2 miles of Columbia River below Vancouver, Wash., and 14 miles of Willamette River below Portland, Oreg. For description of Columbia River see page 1657 and of Willamette River, page 1642. Previous project. Some relief dredging was done between 1866 and 1876. Projects were adopted by the River and Harbor Acts of June 18, 1878; July 13, 1892; June 13, 1902; and March 3, 1905. For further details see pages 1995 and 1998 of Annual Report for 1915, and page 1746 of Annual Report for 1938. Existing project. This provides for a channel 35 feet deep and 500 feet wide in the Columbia River from its mouth to the mouth of the Willamette, 101.5 miles, and thence up Willamette River to Broadway Bridge at Portland 12 miles; 30 feet deep and 300 feet wide from Broadway Bridge to Ross Island, 14 miles above the mouth of Willamette River to be maintained by the port of Port- land. The existing project also provides for maintenance at not to exceed a depth of 35 feet at low water, over such areas in the Portland harbor and Willamette River between its mouth and Broadway Bridge as have been or may be dredged to project depth by the port of Portland; no dredging, however, shall be done by the United States within 50 feet of the pierhead line. In addition, the existing project also provides for the following: A channel 30 feet deep and 300 feet wide in the Columbia River from the mouth of the Willamette River to the interstate highway bridge at Van- couver, Wash., about 5 miles, with two turning basins of the same depth at Vancouver, 800 feet wide and approximately 2,000 and 3,000 feet long for the upper and lower basins, respectively, auxili- ary channels 10 feet deep and 300 feet wide in the vicinity of Cath- lamet, Wash., 30 feet deep and 300 feet wide in St. Helens (Oreg.)

The actual cost for new work, exclusive of amounts expended under previous projects and contributed funds, is $5,384,677. The average annual maintenance cost for the past 5 years is $1,690,872. Local cooperation. Fully complied with. Terminal facilities. At Portland, Oreg., there are under public ownership and open to all on equal terms, three terminals for handling general cargo, bulk grain, coal, phosphate, lumber, oils, and similar commodities. Extensive modernization and rehabili- tation of these public facilities are currently underway as a result of the outcome of the May 1954 primary election when a 6.5- million dollar expenditure of public funds was authorized for this work. Under private ownership and operation there are five general cargo, five flour and grain, six lumber, one cement, one bulk creosote, one salt, and 10 fuel oil and gasoline wharves and piers, besides outfitting and repair, sand and gravel, and construc- tion equipment wharves. Three of the private general cargo ter- minals subscribe to Commission of Public Docks Terminal Tariff 2A and four of the five flour and grain facilities publish terminal tariffs and may therefore be considered to be open to the public on equal terms. The port of Portland Commission, a State of Oregon agency, has completed at Swan Island, modern ship repair and outfitting facilities complete with three dry docks, one of 2,000-ton, one of 12,500-ton and one on long term lease from the U. S. Navy of 14,000-ton capacity. Also available at this facility and available to the public on equal terms are five rail-mounted gantry cranes each of 45-ton capacity, and one truck-mounted crane, as well as machine shops, rail lines, staging, compressed air, steam, electricity, and water. Seven berths are available at the outfitting dock of this facility which is open to all on equal terms. Also located within the harbor are one dry dock of 85-ton capacity, three privately owned marine railways for handling small vessels and barges, as well as several skid-type haulouts on which launches and other small craft can be accommodated. Heavy lift to equipment at the general cargo wharves include 10 locomotive cranes and auto cranes with up 35-ton capacity, one 150-ton swinging boom derrick, one 100-ton swinging boom derrick, one 100-ton shear-leg derrick crane, two 35-ton traveling gantry cranes and two 75-ton floating cranes. At Astoria, Oreg., there is a large municipal terminal with grain elevator and flour mill, facilities for receiving oil products by tanker, and bunkering of vessels. There are also private wharves used for receipt of fish, sand and gravel, and bunkering of fishing vessels. At Vancouver, Wash., below Interstate Bridge, there are two municipal terminal wharves. There are also several privately owned wharves for the shipment of lumber, a fuel and gasoline terminal, and a privately owned grain elevator and wharf. The port of Longview has a public terminal on the Columbia River at Longview, Wash., and the Long-Bell Lumber Co. and Weyerhaeuser Timber Co. have wharves in the same vicinity for 1650 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the shipment of lumber. A privately operated grain elevator for shipment of grain is located at the port terminal; a fuel oil and gasoline terminal is also located at the port dock for the receipt of petroleum products. There is a heavy lift of 125-ton capacity at the public terminal. At other locations on the Columbia River between Portland and Columbia River entrance, there are sufficient private facilities to accommodate the river vessels and fishing craft, and at seven points there are large sawmill docks used exclusively for shipment of lumber in ocean-going vessels. These facilities, with planned extensions, are considered ade- quate for existing commerce. (For further details see Port Series Nos. 33 and 34, Corps of Engineers, published in 1953 and 1954, respectively.) Operations and results during fiscal year. The repair of exist- ing pile dikes and construction of dolphins were completed under two contracts. A total of 11,113,493 cubic yards of material were removed from bars and shoals in the main and side channels; 8,252,738 cubic yards by Government plant, and 2,860,755 by contract, at a cost of $1,235,203 and $530,165 respectively. Hydrographic condition surveys were made at a cost of $143,542. Total costs for the fiscal year were $1,977,472, all for main- tenance. Condition at end of fiscal year. The existing project was com- pleted September 1950. The main channel project was completed in 1933, except that a revision at Harrington Point was made in 1935. The dikes were completed in 1935 and the extension of the Vancouver turning basin in 1939. The auxiliary channel in the vicinity of Longview was completed in 1949, and the improvement of the old mouth of Cowlitz River and the small boat mooring basin at Astoria were completed in 1950. The controlling depth at low water in Columbia River from its mouth to the mouth of Willamette River is 35 feet. Above the mouth of Willamette River the Vancouver channel has a con- trolling depth of 30 feet and in Willamette River from its mouth to Broadway Bridge the controlling depth is 33 feet. Project depths are maintained throughout the year except during short shoaling periods following freshets which generally occur in May, June, and July.

Dredging of the entrance channel to the project depth of 48 feet was continued by the Government hopper dredges Essayons and Biddle during the fiscal year until October 1956, when opera- tions were suspended through the winter storm season. The quantity to be dredged to complete the 48-foot bar channel was approximately 4,980,000 cubic yards in November 1956. An incomplete survey made in March 1957 during rough sea condi- tions indicated that shoaling had probably occurred during the 1658 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 winter months in the amount of 6,800,000 cubic yards. How- ever, extensive scour during the spring freshet, May and June 1957 removed a major part of this material. On April 8, 1957, work was resumed by the Biddle. A total of 8,651,811 cubic yards of material was removed during the fiscal year. Maintenance. A total of 393,960 cubic yards of material was removed from the entrance channel by Government plant. Under two contracts, steel rail and fittings were removed from the abandoned Jetty "A" tramway and from the south jetty tramway. Total costs for the fiscal year were $1,316,733 of which $1,210,078 was for new work and $106,655 for maintenance. Condition at end of fiscal year. The existing project is 62 percent complete. The project as originally authorized, consist- ing of the extension of the south jetty constructed under the pre- vious project, construction of the north jetty and the 40-foot channel depth over the entrance bar, was completed in 1918. Dredging of the 48-foot bar channel initiated April 1956 is 64 percent complete. A total of 15,189,313 cubic yards of mate- rial has been removed to date. A survey made in June 1957 showed a controlling depth in the entrance channel, of 48 feet at mean lower low water except at Clatsop Spit where the controlling depth for the left quarter of the channel was 47 feet. Total costs under the existing project from Federal funds have been $26,282,986, of which $13,444,027 is for new work and $12,838,959 for maintenance. In addition $475,000 and $25,000 were contributed by the ports of Portland and Astoria, respectively, and expended for new work.

Under the provisions of the River and Harbor Act approved March 2, 1945, State or other local interests are required, for the Winchester Bay channel, to furnish free of cost to the United States suitable areas for spoil disposal for initial work and subse- quent maintenance, when and as required, and hold and save the United States free from claims for damages resulting from the improvements; construct, maintain, and operate suitable public terminal and mooring facilities with essential utilities and supply services at the basin, open to all on equal terms, and at their own expense maintain project depths within the mooring and turning basin after its construction has been accomplished. These assur- ances have been received and approved. Total estimated costs for all requirements of local cooperation under terms of the project authorization, amount to $17,200 (1957). The River and Harbor Act of September 3, 1954, provides in connection with construction of Scholfield River channel, that local interests contribute in cash $10,000 toward the cost of the new work; agree to furnish, free of cost to the United States, suitable spoil-disposal areas for initial work and subsequent maintenance, when and as required; and hold and save the United States free from damages due to the construction and maintenance of the project. A non-Federal contribution of $10,000 is re- quired under the terms of the project authorization. Sub- mission of assurances of local cooperation was requested of Port of Umpqua, July 3, 1956. On April 8, 1957, local interests reported inability to furnish required cooperation. Assurances in connection with construction of Gardiner channel were approved December 26, 1947. RIVERS AND HARBORS-PORTLAND, OREG., DISTRICT 1669 Terminal facilities. At Gardiner there is approximately 650 feet of wharf frontage, of which 60 feet is publicly owned. At Reedsport there is about 750 feet of usable wharf frontage, all privately owned. . The port of Umpqua owns 1 wharf with 456 feet of water frontage and another with about 75 feet of water frontage which has not been used generally for commercial shipping. On Bolon Island across the river from Reedsport a wharf has been constructed which has about 5 acres of open stor- age for lumber and is available to all on equal terms. At Win- chester Bay, there is a public landing float with a wooden pile and timber shore approach, and a privately owned wharf used by excursion and commercial fishing vessels. The facilities are considered adequate for present commerce. Operations and results during fiscal year. New work: Re- moval of a rock ledge from the east side of the Winchester Bay channel was accomplished by Government plant and hired labor. Preliminary engineering for construction of the 12-foot channel in Scholfield River was discontinued due to inability of local interests to provide assurances of cooperation and rights-of-way. Maintenance: A total of 574,957 cubic yards of material were removed from the entrance bar and inner channel by Govern- ment hopper dredge at a cost of $124,400. Condition surveys were made at a cost of $13,436. Total costs for the fiscal year were $158,537, of which $16,631 was for new work and $141,906 for maintenance. Condition at end of fiscal year. The existing project is 98 percent complete. The north jetty was completed in 1940. The extension to the original south jetty was completed in 1938 and. construction of a new training jetty on the south side of the entrance to replace the original south jetty which was partially destroyed by storms was completed in 1951. Dredging of a 22-foot channel from the mouth of the river to Reedsport was completed in 1941. The Gardiner channel and turning basin was completed in 1949 and the Winchester Bay channel and moor- ing basin in 1956. Remaining to complete the project is construction of the 12-foot channel in Scholfield River. The controlling depth was 19 feet on the bar, survey of May 1957, and 15 feet from the mouth to Reedsport and 20 feet in the turning basin, survey of August 1956.

This provides for channels 5 feet deep and 50 feet wide from the mouth of Coos River to Allegany on Milli- coma River, mile 13.8 and to Dellwood on South Fork, mile 14, and thence a channel 3 feet deep and 50 feet wide to mile 14.7 on South Fork, including stabilization works on Coos River. Mean lower low water is the plane of reference. The mean of the higher high waters above the plane of reference and the extreme tidal ranges under ordinary conditions at the mouth of Coos River are 7.3 and 11 feet respectively, and there is tidal range of about 1 foot at the head of navigation in both forks. Freshet stages usually reach a height of from 10 to 15 feet at Allegany, head of navigation on the Millicoma River. The estimate of cost of new work (1957) is $498,000. The average annual maintenance cost for the past 5 years was $2,904. The existing project was authorized by the River and Harbor Acts of June 3, 1896 (H. Doc. 237, 53d Cong., 3d sess.) and June 30, 1948 (S.Doc. 124, 80th Cong., 2d sess.). The latest published maps are in these documents. Local cooperation. The River and Harbor Act of June 30, 1948, provides that local interests (a) furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil- disposal areas necessary for construction and future mainte- nance of work when and as required (b) construct, operate, and maintain adequate terminal facilities open to all on equal terms and (c) hold and save the United States free from all damages resulting from construction and maintenance of the improvement. Total estimated costs of all requirements of local cooperation under terms of the project authorization amount to $97,000 (1957). Terminal facilities. There are several small privately owned wharves and landing places on the river that are used by small launches. There are no publicly owned wharves. The project modification provides for the construction of terminal facilities open to all on equal terms. Operations and results during fiscal year. During November 1956 snagging of the channel was accomplished by hired labor and rented equipment. In-April 1957, debris deposited in a section of the Coos River channel by sliding of the river bank, was removed by contract. RIVERS AND HARBORS-PORTLAND, OREG., DISTRICT 1671 Total costs for the fiscal year were $14,522 for maintenance. Condition at end of fiscal year. The originally authorized project providing for a channel from the mouth of Coos River to the head of navigation in both forks to provide a depth of 3 feet generally and 1 foot near the head of navigation, was completed in 1899. No work has been done on the project as modified by the River and Harbor Act of June 30, 1948. Total costs have been $107,676 of which $8,000 was for new work and $99,676 for maintenance.

Assurances of cooperation required by provisions of the River and Harbor Act approved July 24, 1946, have been fully complied with. The River and Harbor Act of June 30, 1948, in connection with Charleston Channel, provides that local interests (1) furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas required for both new work and subse- quent maintenance; (2) agree to construct, maintain, and operate adequate mooring facilities within the basin, and a public land- ing with suitable utility and supply facilities, without profit and open to all on equal and equitable terms; (3) maintain the bulk- head and maintain project depths within the mooring basin; (4) agree to hold and save the United States free from any claims for damages which might result from execution of this im- provement; (5) contribute $40,800 to defray one-half of the estimated cost of constructing the bulkhead; and (6) hold for the free use of the public as a roadway, promenade, or land- ing, a strip at least 100 feet wide, adjacent to and landward of the bulkhead along the northerly, easterly, and southerly sides of the filled area. Assurances of cooperation have been received and approved. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $218,000 (1957). Terminal facilities. At North Bend there is a municipal wharf 649 feet long fronting on the channel and about 1,400 feet of privately owned mill wharves, and three oil docks in the vicinity. At Coos Bay there is a privately owned wharf with a frontage of 1,310 feet, 500 feet of which was constructed in 1952, open to the public on equal terms; several small landings for fishing boats and harbor craft; and two lumber docks with 1,300-foot and 596-foot frontages, respectively. At Eastside, on Isthmus Slough, there is a 200-foot wharf to' accommodate coastal lumber schooners and about 41/ miles above Eastside on Isthmus Slough, there is RIVERS AND HARBORS-PORTLAND, OREG., DISTRICT 1673 a newly constructed mill wharf served by oceangoing barges. At Empire there is a privately owned lumber wharf with a frontage of 545 feet. About 11/2 miles below Empire there is a privately owned lumber and pulp mill wharf with a frontage of 410 feet. These facilities are considered adequate for existing commerce. At Charleston there are two wharves, one public and one private, with usable area of 1,200 square feet and 2,400 square feet, respectively, each equipped with facilities for servicing fishing craft. A float landing extends some 200 feet north of the private wharf. Present facilities are congested and inadequate to accommodate the boats operating in the vicinity. A privately owned floating moorage located on Joe Ney Slough has facilities for mooring approximately 50 fishing vessels. Dur- ing stormy season, vessels from Charleston seek shelter at these moorings, which are entirely inadequate during these periods. Operations and results during fiscal year. New work: Con- struction of the project modification providing for a stone break- water and dredging of a small boat basin at Charleston, initiated by contfact March 1956, was completed September 1956. Maintenance: Dredging of the inner bay channel was ac- complished August 1956 to January 1957 by contract, with a total of 1,472,626 cubic yards of material removed. Government plant removed 1,116,002 cubic yards of material from the bar channel. At the end of the fiscal year, mobilization of equipment and construction of loading dock and access road was in progress by contract, for repair of the north jetty and construction of five pile dikes.

WILLAMETTE RIVER BASIN, PORTLAND, OREG. DISTRICT Location. The Willamette River is formed by the Coast and Middle Forks which join a few miles above Eugene, Oreg., flows north 189 miles, and enters the Columbia River, 101.5 miles above its mouth. The basin has an area of 11,200 square miles and lies between the Cascade range on the east and the coast range on the west. The major tributaries of the Willamette River rise in the Cascade Mountains and consist of the Coast and Middle Forks and the McKenzie, Calapooya, Santiam, Molalla, and Clackamas Rivers. The important tributaries that head in the coast range are the Luckiamute, Yamhill, and Tualatin Rivers. Minor tribu- taries, all of which enter the main stream from the west, are Marys River, Rickreall Creek, and Long Tom River. Existing project. The Flood Control Act of June 28, 1938, approved the general comprehensive plan for flood control, naviga- tion, and other purposes in the Willamette River Basin, as set forth in House Document 544, 75th Congress, 3d session, and authorized $11,300,000 for the initiation and partial accomplish- ment of the plan recommended for initial development; the reser- voirs and related works to be selected by the Chief of Engineers. Subsequent Flood Control Acts, 1941 through 1954, authorized additional flood control and other works and increased the 1678 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 monetary authority to $463,300,000 for the Columbia River Basin, including the Willamette River Basin. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies to reservoir projects. Local cooperation for other projects is shown in individual reports for those projects. Operations and results during fiscal year. The progress of preliminary work and status of operations on projects selected for construction are given in individual reports for those projects.

FLOOD CONTROL--PORTLAND, OREG., DISTRICT 1679 Condition at end of fiscal year. The following projects have been completed and are in 'continuous operation: Fern Ridge Reservoir was completed in August 1951; Cottage Grove Reser- voir, March 1952; and Dorena Reservoir, October 1952. The Detroit and the Lookout Point Reservoir projects are complete except for miscellaneous items of minor construction and improve- ment, and are in operation for flood control and power generation purposes. Construction of Hills Creek and Cougar Reservoirs has been initiated. Advance planning for construction of Green Peter and Holley Reservoir projects was in progress during the fiscal year. Details of operation, construction, and the financial status of the projects are given in the individual reports. During the low-water season, July-September, supplemental water releases are made from the Willamette River Basin reser- voirs for conservation purposes. Interests which benefit from the increased downstream flows include irrigation, navigation, power, pollution abatement, and recreation. Although optimum regula- tion cannot be provided for every conservation interest, water released from the reservoirs during the low-water season for a particular purpose will usually provide benefits to other conserva- tion uses as well. The basic policy is to provide the most bene- ficial overall regulation, consistent with established water-use priorities. The following table summarizes the status of projects authorized under "Willamette River Basin, Portland, Oregon District."

HILLS CREEK RESERVOIR, WILLAMETTE RIVER BASIN, OREG; Location. On the middle fork Willamette River, 47.8 miles from the mouth and 26.5 miles upstream from the Lookout Point Dam. The middle fork Willamette River rises on the west slope of the Cascade Range and flows northwesterly to its junction with the coast fork Willamette River 4 miles southeast of Eugene, Oreg., to form the main Willamette River. The location of the dam is about 45 miles southeast from Eugene, Oreg. The drainage area above the dam site is 389 square miles. Existing project. The plan of improvement provides for con- struction of an earth-and-gravelfill dam about 2,150 feet long at the crest and 338 feet high above the foundation. A gated spill- Way of the straight chute type with a flip bucket will be located in the right abutment. The dam will form a reservoir about 8.5 miles long, with a usable storage capacity of 249,000 acre-feet at full pool. A diversion tunnel, an outlet tunnel, and a power tunnel will be located in the right abutment. The powerhouse with two 15,000-kilowatt units will be located between the spillway and the earth dam. The Hills Creek Reservoir project is an integral unit of the comprehensive plan for development of the water resources of the Willamette River Basin. The Hills Creek and Lookout Point Reservoirs will be operated as a unit for control of floods and generation of power on the Middle Fork Willamette River. These reservoirs, in conjunction with the Dexter reregulating dam and the Fall Creek flood-control reservoir, will effectively control floods on the Middle Fork and provide maximum efficient generation of hydroelectric power. The Hills Creek Reservoir project was authorized by the Flood Control Act approved May 17, 1950. The estimated cost (1957) is $8,159,000 for lands and damages including relocations, and $31,841,000 for construction, a total of $40,000,000. Local cooperation. None required. Operations and results during fiscal year. Construction of the river diversion tunnel initiated in May 1956 was completed by contract. Logging of the reservoir area was in progress by the U. S. Forest Service and Pope and Talbot, Inc., and clearing of approximately 421 acres was accomplished under two contracts. Clearing of an additional 980 acres in the reservoir area was in progress at the end of the year, under four contracts. FLOOD CONTROL---PORTLAND, OREG., DISTRICT 1683 The project engineer office was complete. Construction of a bridge crossing Salt Creek on relocated County Road No. 360 was 37 percent complete. Contracts were awarded at the end of the year for construction of west side road lower and upper bridge crossings. At the end of June 1957, a continuing contract was awarded for construction of the dam, outlet works, power intake works, and appurtenant work. Planning and engineering were continued during the year for proposed road relocation work and for construction of the dam, powerhouse and appurtenances. Costs for the fiscal year were $2,232,091. Condition at end of fiscal year. Construction of the project initiated May 1956 is 8 percent complete. The river diversion tunnel is complete and reservoir clearing operations are in progress. Bridge construction for road relocation has been started. Construction of the dam and appurtenances will be initiated July 1957. Preparation of contract plans and specifica- tions for road relocations is well advanced. All lands and flowage rights required for the project have been essentially obtained. Total costs to June 30, 1957 have been $3,197,916, for new work.

LOOKOUT POINT RESERVOIR (MERIDIAN SITE), WILLAMETTE RIVER BASIN, OREG. Location. On the middle fork Willamette River at meridian site, 21.3 miles from the mouth. The middle fork Willamette River rises in Lane County on the western slope of the Cascade range and flows northwesterly to its junction with the coast fork, which is the head of the main stem Willamette River. The dam site is approximately 22 miles southeast from Eugene, Oreg. The drainage area tributary to the reservoir is 991 square miles. Existing project. The plan of improvement provides for the construction of a main dam at Meridian site and a reregulating dam 3 miles downstream at Dexter site. Both dams are earth- and-gravel-fills with concrete gravity spillways and have power- generating facilities. The main dam has a height of 258 feet from foundation to dock and is 3,381 feet long at the crest, 1684 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 forming a reservoir 14.2 miles long providing usable storage of 349,400 acre-feet at full pool level. The spillway, 274 feet long, is a gate-controlled overflow type, forming the right abutment. Out- let works consisting of slide-gate controlled conduits pass through the spillway section. The powerhouse has three main generating units with a capacity of 120,000 kilowatts. The reregulating dam has a maximum height of 107 feet above the foundation and is 2,765 feet long at the crest, forming a pool extending upstream to the main dam and providing pondage to regulate Lookout Point powerhouse water releases to a uniform discharge. The spillway consists of a gate-controlled overflow section 509 feet long form- ing the right abutment. Flow regulation will be accomplished by use of the spillway gates and releases through the powerhouse, which contains one 15,000-kilowatt unit. Lookout Point and Dexter Dams will be operated as a single unit of a coordinated system of dams to protect Willamette River Valley against floods, to provide needed hydroelectric power, and to increase low water flows for navigation, irrigation, and other purposes. The existing project, authorized as a unit of the comprehensive plan for flood control and other purposes in the Willamette River Basin, was authorized by the Flood Control Act of June 28, 1938, House Document 544, 75th Congress, 3d session. The Flood Con- trol Acts of December 22, 1944, and July 24, 1946, modified the project to provide for recreational facilities and the Flood Control Act of May 17, 1950, House Document 531, 81st Congress, 2d ses- sion, modified the project to provide for power generating facilities. The estimated cost (1957) is $38,243,000 for lands and damages including relocations, and $49,627,000 for construction, a total of $87,870,000. Maintenance and operation costs incurred in the past 3 years amount to $813,419. The project has been under major operation and maintenance status for one year only. Average cost for the past 3 years was $271,140. Operation and results during fiscal year. In addition to ordi- nary maintenance, repair, and operation; miscellaneous items of construction, and modification and improvement were accom- plished during the fiscal year. Included were removal of reservoir debris, miscellaneous mechanical and electrical work, construction of an oil storage shed, and construction of public use facilities at the Hampton recreational area. Relief wells and a pumping system were installed at the Minnow Creek slide area along relocated Highway No. 58. Conditions were not materially im- proved and at the end of June 1957 bids were invited for the relocation of a section of Highway No. 58. At the end of the fiscal year work was in progress on drainage and shore line improvements at both Lookout Point and Dexter reservoirs and on modification of the outdoor 15 kilovolt bus at Lookout Point powerhouse. During the fiscal year 1957 a total of 478,346,000 kilowatt-hours of electrical power energy were generated at the project, of which FLOOD CONTROL--PORTLAND, OREG., DISTRICT 1685 476,997,000 kilowatt-hours were delivered to Bonneville Power Administration. A total of 69,760 persons visited the reservoir area for recreational purposes during the fiscal year. Two significant floods and three freshets were registered during the fiscal year 1957 in the Middle Fork Willamette Basin. How- ever, due to regulation of Lookout Point and Dexter Reservoirs, only slight flooding was reported during one of these floods. Evacuation of the reservoir during the fall was delayed because of conditions at the Minnow Slide area on the south side of the Lookout Point Reservoir. On December 11, 1956, a storm resulted in a peak inflow into Lookout Point Reservoir of 60,300 c.f.s. Although the release from the dam during the peak inflow was only 465 c.f.s., the runoff from uncontrolled areas caused slight flooding in the Middle Fork Willamette River below the dam, but no damage was reported. The storm of February 26, 1957, which had a peak inflow of 31,300 c.f.s., and the three smaller freshets were completely controlled at the dam. Evacuation of the Lookout Point Reservoir during the fall season was delayed to prevent sliding during drilling of wells and installation of pumps in the Minnow slide area. The same slide area limited the evacuation of stored flood waters. The drawing down of the reservoir was restricted to only 0.6 foot per day in order to minimize sliding in the Minnow area. Conservation filling of the reservoir began on February 1, 1957. However, during the period February 23-April 5, 1957, the reser- voir was above scheduled pool, due to the storing of flood waters from the storm of February 26, 1957, and the limit placed by the slide area on withdrawing the excess waters. The reservoir reached maximum conservation pool, elevation 926, on May 19, 1957. Toward the end of June 1957 the pool was raised to elevation 927.5, one and one-half feet above maximum conserva- tion -pool, and held at approximately that level for the purpose of clearing debris from the Lookout Point Reservoir. Total costs for the fiscal year were $668,502, of which $306,224, was for new work and $362,278 for maintenance, operation, and care. Condition at end of fiscal year. Construction of the project initiated May 1947 is complete except for the accomplishment of minor items of modification and improvement. At Lookout Point powerhouse, generating units Nos. 1 and 2 were placed in commercial operation December 16, 1954 and February 16, 1955 respectively. The third unit was placed on the line April 24, 1955. At Dexter powerhouse the single unit was placed on the line May 16, 1955. Use of Dexter dam for reregulating the fluctuating flow from the Lookout Point units was effected in December 1954. Total costs have been $86,984,846 of which $86,171,427 is for new work and $813,419 for operation and maintenance. 1686 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,1957 Power production and revenues. During the fiscal year 1957 a total of 478,346,000 kilowatt hours were generated, of which 1,349,000 kilowatt hours were used for operation of the project, and 476,997,000 kilowatt hours were delivered to the Bonneville Power Administration, the marketing agency, for disposition. Revenues allocated to the project for the year amounted to $1,900,000.00, of which $238,151.35 was for repayment of operat- ing expenses applicable to power, $986,517.00 for repayment of interest expense applicable to power, and $675,331.65 for amorti- zation of construction costs, including replacements applicable to power. Of a total of $86,984,845.94 expended to date on the project for construction, operation and maintenance, and re- placements, the amount of $39,066,704.43 or 45 percent has been for direct and allocated portions of power features.

COTTAGE GROVE RESERVOIR, WILLAMETTE RIVER BASIN, OREG. Location. On the Coast Fork of Willamette River, 29 miles from the mouth. The Coast Fork rises in Douglas County, Oreg., on the western slope of the Cascade Range and the northern slope of the Calapooya Range, flows north for 49 miles, and unites with the Middle Fork to form the main Willamette River. The drainage area tributary to this reservoir is 104 square miles. Existing project. The plan of improvement provides for con- struction of an earthfill dam, 1,750 feet long at the crest, rising 95 feet above the stream bed, with a reservoir providing for usable storage of 30,000 acre-feet. The spillway, 264 feet long, is a con- crete, gravity, overflow type forming the right abutment. Outlet works, consisting of three gate-controlled conduits, pass through the spillway section. The reservoir is operated as a unit of the coordinated reservoir system to protect the Willamette River Valley and to increase low water flow for navigation. The existing project was selected for construction under the general authorization for the Willamette River Basin, contained in the Flood Control Act approved June 28, 1938. The Flood Control Acts of December 22, 1944, and July 24, 1946, modified the project to provide for recreational facilities. The actual cost for new work is $1,821,793.94 for construction and $551,500 for lands and damages, a total of $2,373,293.94. The average annual maintenance and operation cost for the past 5 years was $30,605. Local cooperation. None required. Operations and results during fiscal year. The dam and reser- voir. were in normal operation throughout the fiscal year with ordinary maintenance accomplished as required. A total of 45,073 persons visited the reservoir area for recreational purposes. Two significant freshets occurred on the Coast Fork Willamette River in fiscal year 1957 and both were completely controlled at the dam. The peak inflow to the reservoir occurred on February 1688 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 26, 1957 and was estimated at 4,350 c.f.s. The outflow at the same time was 110 c.f.s. It required 21,660 acre-feet of storage to regulate the freshet. Reservoir releases during August-October 1956, in coordination with releases from other reservoirs in the Willamette River Basin, substantially increased the low natural flows of Coast Fork and Willamette Rivers in the interest of navigation, and for other purposes. Conservation filling of Cottage Grove Reservoir began February 1, 1957. However, due to below-normal precipitation from mid- April to mid-May 1957, the filling fell behind schedule. Precipita- tion during the latter half of May was above normal and helped make up the deficiency. Maximum conservation pool, elevation 790, was reached on May 26, 1957, about 8 days later than scheduled. Total costs for the fiscal year were $30,319. Condition at end of fiscal year. Construction of the project initiated August 1940 was completed April 1952. The dam and reservoir have been in continuous operation since September 1942. Total costs to June 30, 1957 have been $2,747,694 of which $2,373,294 was for new work and $374,400 for maintenance and operation and care.

DORENA RESERVOIR, WILLAMETTE RIVER BASIN, OREG. Location. Dorena Reservoir is located on Row River, Oreg., 7 miles from the mouth. Row River rises in Lane County on the western slope of the Cascade Range, flows northwest for 19 miles, and enters the Coast Fork of Willamette River 191/2 miles above the mouth. The drainage area, tributary to this reservoir, is 265 square miles. Existing project. The plan of improvement provides for con- struction of an earthfill dam, 3,388 feet long at the crest, rising 145 feet above the streambed, with a reservoir providing usable storage capacity at normal pool level of 70,500 acre-feet. The spillway, 200 feet long, is a concrete gravity, overflow type, form- ing the right abutment. Outlet works consisting of five slide gate-controlled conduits pass through the spillway section. The reservoir, controlling practically the entire drainage area of Row River, will be operated as a unit of the coordinated reservoir system to protect the Willamette River Valley and to increase low water flows for navigation, and for other purposes. FLOOD CONTROL--PORTLAND, OREG., DISTRICT 1689 The existing project was selected for construction under the general authorization for the Willamette River Basin contained in the Flood Control Act approved June 28, 1938. The Flood Control Acts of December 22, 1944, and July 24, 1946, modified the project to provide for recreational facilities. The actual cost of new work is $13,517,101. The average annual maintenance and operation cost for the past 5 years was $34,115. Local cooperation. None required. Operations and results during fiscal year. The dam and reser- voir were in operation throughout the fiscal year with ordinary maintenance accomplished as required. In addition, cleanup of debris from the reservoir was accomplished by contract. A total of 28,288 persons visited the reservoir area during the fiscal year for recreational purposes. Two floods and two freshets occurred in the Row River Basin. One flood required surcharge storage in the reservoir to control. Otherwise, the functioning of the Dorena Reservoir was near normal during the 1957 fiscal year. The February 26, 1957 flood had a peak inflow of 11,700 c.f.s. as compared to the peak of 18,200 c.f.s. on December 11, 1956. However, its total volume was much greater and flood waters began going over the spillway at 11.30 p.m. on February 26 and continued until 5 p.m. February 28. Maximum pool was reached at 3 p.m. on February 27 when it registered elevation 836.77, 1.77 feet above the crest of the spillway; but at no time was the outflow from the dam permitted to go above the prescribed maximum of 5,000 c.f.s. Summer releases from Dorena Reservoir to increase the low natural flows of the Coast Fork and Willamette Rivers began on July 30, 1956, and continued until September 5, 1956, when all of the stored water, with the exception of a few acre-feet left for minimum releases, was exhausted. Conservation filling began on February 1 and continued on schedule with the exception of storing the flood waters on February 26 and March 6, 1957. Below normal precipitation from the middle of April to the middle of May 1957, resulted in filling at a rate less than scheduled. from April 24 on. Maximum pool reached during the conservation filling season was 831.89 on June 19, 1957, 0.11 foot below the maximum conservation pool. Total costs for the fiscal year were $44,794.

Location. On the Long Tom River, 23.6 miles from the mouth. The Long Tom River rises in Lane County, Oreg., on the eastern slope of the coast range, flows north for 50 miles, and enters the Willamette River 147 miles above its mouth. The drainage area tributary to this reservoir is 252 square miles. Existing project. The plan of improvement provides for con- struction of an earthfill dam, 6,360 feet long at the crest, and two auxiliary dikes, 850 feet and 3,680 feet long, along the north- easterly boundary of the reservoir. The main dam has a maxi- mum height of 44 feet above the streambed. The spillway, lo. cated near the left abutment, consists of a gravity section concrete overflow structure controlled by six automatic radial gates. Out- let works are located in the spillway structure. The project in- cludes rectification of the channel of Long Tom River downstream from the dam. The reservoir, having a usable storage capacity of 101,200 acre-feet, at full pool, protects the Long Tom River Valley and is being operated as a unit of the coordinated reservoir system to protect the Willamette River Valley generally and to increase low water flows for navigation. The existing project was selected for construction under the general authorization for the Willamette River Basin contained in the Flood Control Act approved June 28, 1938. The Flood Con- trol Acts of December 22, 1944, and July 24, 1946, modified the project to provide for recreational facilities. The actual cost of new work is $3,683,145 for construction :and $812,635 for lands and damages, a total of $4,495,780. The average annual maintenance and operation cost for the past 5 years was $46,332. Local cooperation. None required. Operations and results during fiscal year. The repair and restoration of bank protection works along Long Tom River down- stream from Fern Ridge Dam, initiated in fiscal year 1956, was completed by contract. In June 1957, additional repair and re- habilitation of bank protection works at various locations along both banks of the Long Tom River, were in progress, by contract. At the end of the year a contract was also awarded for the drilling and developing of a water well. Ordinary maintenance and operation continued throughout the year. With the exception of a deviation in the filling schedule, opera- tion of Fern Ridge Reservoir was normal during the fiscal year 1957. Two freshets occurred during the year; the highest occurred February 26th with a 7,000 c.f.s. peak inflow. Both freshets were completely controlled at Fern Ridge Dam. FLOOD CONTROL-PORTLAND, OREG., DISTRICT 1691 Drawing down of the reservoir was not initiated until after September 1956, Labor Day, in order to give maximum benefit for recreational activities. During the months of September and October 1956 the reservoir was drawn down to minimum conser- vation pool. The reservoir releases, in coordination with re- leases from other reservoirs in the Willamette River 'Basin, substantially increased the low natural flow of Willamette River in the interest of irrigation, navigation, pollution abatement, and fish life. Conservation filling of Fern Ridge Reservoir took place during February-May 1957. However, due to the below normal precipi- tation predicted for the month of April 1957 and the fact that the reservoir failed to fill in half of the past years of operation, approval was obtained to fill the reservoir at a higher rate than the normal filling schedule. As a result the reservoir was filled and reached the maximum conservation pool on May 7, 1957. During the fiscal year a total of 199,849 persons visited the project for recreational purposes. Total costs for the fiscal year were $45,077. Condition at end of fiscal year. Construction of the project initiated April 1940 was completed August 1951. The dam and reservoir have been in continuous operation since December 1941. Total costs to June 30, 1957, have been $5,068,212, of which $4,495,780 was for new work and $572,432 for maintenance, operation, and care.

Cleanup of reservoir debris was completed and a log trash boom installed at Big Cliff Reservoir. Facilities at Minto egg-collecting station were also improved. At the Detroit Dam spillway, the repair of the lower regulating outlets and installation of steel liners for protection from high velocity discharge flows were nearing completion with all steel in place and welding and grinding in progress. During the fiscal year a total of 525,102,000 kilowatt-hours of electrical power energy were generated at the project of which 521,973,000 kilowatt-hours were delivered to Bonneville Power Administration. A total of 93,302 persons visited the reservoir area for recreational purposes during the fiscal year. Two significant floods and two minor freshets occurred during the fiscal year. Flooding in the North Santiam Basin was avoided by the regulation of Detroit and Big Cliff reservoirs, but the lower Santiam River flooded several times during' the fiscal year. Conservation filling of the reservoir was completed on schedule. ' The storm of December 11, 1956 resulted in a peak inflow of 34,000 second-feet, and was the largest flood to occur in the North Santiam Basin during the fiscal year. The flood required 110,000 acre-feet of storage to control it. The storm of February 26, 1957 had a peak inflow of 23,700 c.f.s. Conservation filling of the reservoir lagged behind schedule during February due to below normal precipitation. However, after the storm of February 26, 1957 filling of the reservoir was maintained on schedule. Maximum conservation pool, elevation 1563.5, was reached on May 9, 1957. To facilitate removal of debris from Detroit reservoir, the pool was raised to elevation 1567.0 and held at approximately that level during June 1957. Total costs for the fiscal year were $733,509, of which $348,698 was for new work and $384,811 for maintenance, operation, and care. Condition at end of fiscal year. Construction of the project initiated in May 1947 is complete except for the accomplishment of minor modifications and improvements. The two generating units at Detroit powerhouse were placed in commercial operation June and October 1953, respectively. At Big Cliff powerhouse the single generating unit was placed on the line June 1954. Use of Big Cliff dam for regulating the fluctuating flow from the Detroit units was effected in October 1953.

INSPECTION OF COMPLETED FLOOD-CONTROL WORKS Funds in the amount of $35,500 have been allotted to June 30, 1957, to cover costs of inspections of completed local flood-control protection projects. The purposes of the inspection are to determine the condition of the completed works and to ascertain whether those works are being properly maintained by local interests. Operations and restlts during fiscal year. A total of 51 diking and drainage districts (17 in Washington and 34 in Oregon) along the Columbia River; and levees and revetments at 12 districts or locations along various Oregon coast streams were inspected. Bank-protection works at 22 locations in Willamette River Basin were also inspected. In most cases a representative of the diking districts accompanied the Portland District Inspector in making the inspections of their districts. Deficiencies in maintenance and the need for repairs were pointed out to the diking districts' representatives on the ground and a report was made for each district inspected on the conditions found with recommendations for correction of deficiencies. Copies of these reports were furnished the diking districts concerned. FLOOD CONTROL--PORTLAND, OREG., DISTRICT 1715 The campaign to improve maintenance of completed Federal projects initiated by the House Appropriations Committee on Civil Functions, was continued. Periodic contact was maintained with the uncooperative areas reported in fiscal year 1956, to ascertain any change in their attitude and to provide technical assistance if requested. Of the 86 local flood-protection projects in the Port- land, Oreg., District requiring maintenance by local interests, eight were considered deficient in maintenance work, which in- cludes two projects built under emergency authority. John Drain- age District, which was built under emergency authority, was removed from the delinquent list. Costs for the fiscal year were $7,033. Total costs to June 30, 1957, have been $32,756.

Coast and Geodetic Survey Charts Nos. 6300, 6450, and 6460.) Previous projects. Project adopted by the River and Harbor Act of August 2, 1882, contemplated clearing and maintaining the navigable portions of the Skagit, Stillaguamish, Nooksack, Snohomish, and Snoqualmie Rivers, Wash., free from snags, debris, and drift, by means of a shallow-draft stern-wheel snag boat constructed for this purpose. For further details, see page 2003 of Annual Report for 1915 and page 1869 of Annual Report for 1938. Existing project. This provides for maintenance of Puget Sound and its tributary waters by snagging and dredging. The actual cost for new work was $43,337. The average annual maintenance cost during the past 5 years was $114,230. The existing project was adopted by the River and Harbor Act of July 13, 1892 (Annual Report for 1893, p. 1719 1720 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 3425). The latest published map is in the Annual Report for 1913, page 3127. Local cooperation. None required. Terminal facilities. The terminal facilities at the numerous localities on Puget Sound and its tributary waters are, in general, considered adequate for existing commerce. Operations and results during fiscal year. The U. S. snag boat W. T. Preston was operated a total of 10 months at a cost of $113,589, accomplishing the following work: Dredg- Obstructions removed ing Waterway (cubic yards) Snags Piles Miscellaneous Duwamish Waterway---------- .........----------......... 367 -. __... 1 scow.

No permanent results are obtainable, but the maintenance of existing channels requires practically continuous operation of the snag boat. The controlling depths range from 1 to 40 feet at mean lower low water. The total costs of the existing project to June 30, 1957, have been $43,337 for new vork and $2,349,295 for maintenance, a total of $2,392,632.

BLAINE HARBOR, WASH. Location. This harbor is in northwestern Washington, just south of the international boundary on the easterly shore of Semiahmoo Bay and Drayton Harbor. It is about 100 miles north of Seattle. (See U. S. Coast and Geodetic Survey Chart No. 6399.) RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1721 Existing project. This provides for enlargement of the existing mooring basin by dredging an area of 14.7 acres to a depth of 12 feet below mean lower low water, with suitable breakwater protec- tion. This protection consists generally of a new rubblemound breakwater about 1,500 feet long, and maintenance of about 850 feet of existing breakwater. The diurnal range of tide is 9.5 feet, and the extreme range is 17 feet. The estimate of cost for new work (July 1957) is $358,000. The existing project was authorized by the River and Harbor Act of September 3, 1954. (See H. Doc. 240, 83d Cong., 2d sess., which contains the latest published map.) Local cooperation. Provisions of the 1954 River and Harbor Act require local interests to (a) furnish without cost to the United States all lands, easements, rights-of-way, and disposal areas, suitably bulkheaded where necessary, for construction and subsequent maintenance when and as required; (b) hold and save the United States free from damages due to construction and maintenance of the improvement; (c) accomplish and maintain alterations as required in water, sewer, drainage, and other utility facilities, including diversion of the existing sewer draining into the boat basin area; (d) maintain the present mooring basin to a depth of at least 12 feet below mean lower low water, maintain that portion of the existing breakwater not included in the Federal project, and maintain the basin extension to project dimensions; and (e) construct, maintain, and operate adequate mooring facili- ties, utilities, and a public landing with suitable service and supply facilities, open to all on equal terms. The Port of Bellingham Commission, local sponsor of the project, formally agreed to furnish the necessary local cooperation, by resolution adopted August 17, 1956. The city of Blaine, in cooperation with the port, has completed the diversion channel for a sewer which previously drained into the area of the proposed mooring basin. The Port of Bellingham and the city of Blaine own all land where easements are required. Permission was granted on January 22, 1957, by the city of Blaine for use of spoil- disposal area, together with right of entry. The Port of Belling- ham has completed the bulkhead for spoil-disposal areas. All real estate requirements have also been completed. Terminal facilities. There are six publicly owned wharves at Blaine. One is a general cargo wharf. The other five are within the existing moorage basin and are used for fish landings, small- craft moorage, service, and repair. All are open to the public. The boat basin also has floats for public moorage of small craft. In addition, a private fish packing concern has two wharves, a marine way, and drydock at the northern end of Semiahmoo Spit at the entrance to Blaine Harbor. These facilities are not open to the public. Operations and results during fiscal year. Project design, plans and specifications were completed, by hired labor. Dredg- ing of the boat basin extension and construction of the breakwater were commenced in May 1957 by contract. Approximately 65 percent of the total quantity to be dredged, or 107,000 cubic yards, 1722 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 was dredged from the area of the small-boat harbor extension. Total costs for the fiscal year were $38,249, all for new work. Condition at end of fiscal year. Advance planning has been completed, and construction is about 12 percent complete. Re- maining work to complete the project includes dredging and place- ment of rock in the breakwater. The bulkhead for retention of dredged material has been completed by the Port of Bellingham. Costs to June 30, 1957, have been $38,249, all for new work.

BELLINGHAM HARBOR, WASH. Location. This harbor is a part of Bellingham Bay, an arm of Puget Sound, about 18 miles south of the international boundary and about 100 miles north of Seattle. (See U. S. Coast and Geodetic Survey Chart No. 6378.) Previous projects. The original project adopted by the River and Harbor Act of June 13, 1902, contemplated dredging Whatcom Creek Waterway to a depth of 12 feet and 200 feet wide from deep water to the railroad bridge, a distance of 1,200 feet, and to its full width (363.2 feet) above the bridge, an additional distance of 1,950 feet. For further details see page 2006 of Annual Report for 1915 and page 1888 of Annual Report for 1938. Existing project. This provides for (1) dredging a channel in Whatcom Creek Waterway from deep water to the head of the harbor, 363.2 feet wide, 26 feet deep at mean lower low water for the outer 3,800 feet, and 18 feet deep for the inner 1,300 feet; (2) Squalicum Creek Waterway, including dredging an entrance chan- nel 200 feet wide and 26 feet deep from deep water in the bay to the main pierhead line, and maintenance of the southerly half and westerly end of the Squalicum Creek basin to a depth of 26 feet at mean lower low water, provided that no dredging can be done within 75 feet of wharves, piers, or similar structures; and (3) a small-boat basin adjacent to Squalicum Creek Waterway by con- struction and maintenance of two sections of rubblemound break- water with combined length of 3,900 feet, including removal of the existing rubblemound breakwater heretofore maintained under the existing project and using the rock therefrom in construction of RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1723 the new breakwater, and including maintenance of minimum depths of 12 feet in the entrances to the basin. The extreme tidal range is about 16 feet. The range between mean lower low water and mean higher high water is 8.6 feet. The-estimated cost for new work (July 1957) is $1,431,000, exclusive of $11,000 U. S. Coast Guard funds, and of amount expended on previous project. The average annual maintenance cost during the past 5 years was $14,502. The existing project was authorized by the following: Acts Work authorized Documents 1 June 25, 1910 H.

Recommended modifications of project. The Chief of En- gineers, in a report dated April 18, 1957, recommended modifica- tion of the existing project to provide in Whatcom Creek Water- way a channel 30 feet deep, at mean lower low water, from water of that depth in Bellingham Bay to a point not nearer than 750 feet from the inner end of the waterway over the full width; at an estimated cost to the United States of $83,700 (December 1955) for construction and $1,000 annually for maintenance in addition to that now required; subject to certain conditions of local coopera- tion, including a contribution in cash or equivalent work of 3.9 percent of the cost of channel dredging, a contribution estimated at $3,400 (December 1955). Local cooperation. Fully complied with, except the provisions of the 1954 River and Harbor Act, which require local interests to (a) furnish without cost to the United States all lands, ease- ments, rights-of-way, and suitable spoil-disposal areas for new work and subsequent maintenance, when and as required, includ- ing title to that portion of the breakwater already constructed by them and including the right to remove rock from the previous project breakwater for use in the new Federal work; (b) hold and save the United States free from damages due to construction and maintenance of the improvement; (c) remove the timber-pile portions of the existing breakwater, perform all dredging required to provide and maintain in the basin a depth of 12 feet at mean lower low water; (d) construct protective dolphins at the ends of the breakwaters when and as required; and (e) provide, maintain, and operate adequate moorage facilities, utilities, and a public landing with suitable service and supply facilities open to all on equal terms. The Port of Bellingham has partially completed the required work by improving the existing boat basin since 1945 by construct- ing breakwaters, bulkheads, and floats, and by dredging; and on 1724 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 August 17, 1956, adopted a resolution formally accepting the responsibility for complying with the terms of local cooperation. The Port of Bellingham owns all rights-of-way and has agreed to furnish easements to the Government when and as required. However, it has been determined that no real estate rights will be required, as the project is within the navigable waters of the United States. The estimated total cost of the local cooperation features required by the 1954 Act is $571,000. The Port has spent approximately $770,000 on improvement of the boat basin. Of this amount, about $185,000 was spent in anticipation of com- pletion of the Federal work and is applicable to local cooperation requirements, leaving $386,000 to be expended by the Port to complete the requirements. Terminal facilities. There are 23 wharves and piers in Belling- ham Harbor; eight are located on Whatcom Creek Waterway, four on Squalicum Creek Waterway, and 11 on Bellingham Bay. Three wharves on Whatcom Creek Waterway serve general cargo termi- nals. One of these, which is publicly owned and operated, is suitable for use by oceangoing vessels; the other two are privately owned and operated and serve vessels in the Puget Sound trade. The four wharves on Squalicum Creek Waterway are publicly owned; one oil-handling wharf is publicly operated; the other three are privately operated. The latter three wharves and the other 15 are used for various industrial purposes. These terminal facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Dredging totaling 25,613 cubic yards was completed by contract in June 1956 at a cost of $17,263. New work: Engineering and design were completed, and a con- tract was awarded for removal of existing rock breakwater and construction of new rock breakwater. Construction activity dur- ing the fiscal year was limited to mobilization of equipment. Costs were $18,753 for new work, and $21,905 for maintenance, a total of $40,658. Condition at end of fiscal year. The existing project is 9 percent complete. Dredging of Whatcom Creek Waterway was completed in 1913. Dredging of the entrance channel in Squalicum Creek Waterway was completed in 1931, and local interests have since dredged the southerly half and westerly end of Squalicum Creek basin. In 1934, they constructed a detached rubble breakwater 1,500 feet long south of the basin, and later constructed pile ex- tensions to it. Since 1945, they have also constructed part of the easterly section of the Federal project breakwater (see "Local cooperation"). Removal of existing breakwater and construction of new rock breakwater authorized by the 1954 River and Harbor Act, remain to be done to complete the project. Engineering and design have been completed. Contract has been awarded for removal of exist- ing rock breakwater and construction of new rock breakwater, and contractor has started mobilization of equipment. In June 1957, the inner 1,200 feet of Whatcom Creek Waterway had a controlling depth of 18 feet, except along the edges of the RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1725 waterway, and a depth of 26 feet, except along the edges, in the outer 4,400 feet of the waterway. In September 1955, the Squali- cum Creek Waterway entrance channel was 23.1 feet deep over a width of 100 feet, and the basin was 20.3 feet deep except near the edges and at the head of the waterway. The costs under the existing project to June 30, 1957, have been $130,766 for new work and $164,978 for maintenance, a total of $295,744.

ANACORTES HARBOR, WASH. Location. Anacortes Harbor is on the northern point of Fidal- go Island in Puget Sound, 17 miles south of Bellingham, Wash., and 64 miles north of Seattle. The main harbor is on Guemes Channel. (See U. S. Coast and Geodetic Survey Chart No. 6377.) Existing project. This provides for (1) a channel in Capsante Waterway, 12 feet deep at mean lower low water and 150 to 250 feet wide, between the east side of Q Avenue and deep water in Fidalgo Bay, a distance of 2,850 feet; and (2) a mooring basin 12 feet deep at mean lower low water, 570 feet wide, and 960 feet long adjacent to north side of Capsante Waterway, protected by two pile breakwaters, 370 feet and 350 feet long, east and south- east of the basin, respectively. The tidal range between mean: lower low water and mean higher high water is 8.2 feet. The extreme range is about 15.5 feet., The estimated cost for new work (July 1957) is $196,000, ex- clusive of $51,000 contributed funds.

The cost of this portion was last revised in 1954 and was estimated to be $9,000. The average annual maintenance cost during the past 5 years was $4,751. Local cooperation. Fully complied with, except provisions of the 1954 River and Harbor Act, which require local interests to (a) furnish without cost to the United States all lands, easements, rights-of-way and spoil-disposal areas, suitably bulkheaded where necessary, for construction and maintenance of the improvement when and as required; (b) hold and save the United States free from all damages due to construction and maintenance of the im- provements; (c) provide and maintain adequate mooring facilities and a public landing with service and supply facilities open to all on equal terms; (d) maintain to project dimensions those portions of the basin where mooring facilities are provided; and (e) con- tribute in cash or equivalent work 14.5 percent of the cost of dredg- ing the moorage basin and constructing the breakwater. By Resolution No. 204, adopted March 29, 1956, the Port Commission of the Port of Anacortes agreed to comply with all requirements of local cooperation, and to make a cash contribution, including the 14.5 percent required, covering all costs in excess of $150,000 for the project modification authorized by the 1954 River and Harbor Act. On October 1, 1956, the Port of Anacortes contributed $28,000 toward the cost of the project. The Port of Anacortes furnished permit dated August 31, 1956, giving permission to the Port of Anacortes to place dredged material as fill on private property between 8th and 11th Streets and Q and R Avenues in Anacortes. On September 13, 1956, permit was received from the Great Northern Railway Co. for placement of dredging effluent pipes across the railway company's right-of-way and for disposal of fill material upon certain property of the railway company at Anacortes. These instruments completed the local real estate requirements for the construction. The Port has also provided bulkheads as required. Terminal facilities. There are 23 terminals in the port of Anacortes; 16 on Guemes Channel, one on Capsante Waterway, and six on Fidalgo Bay. Three terminals on Guemes Channel are open for public use; of these, one is publicly owned and operated and used for handling general cargo in foreign and domestic trade; and two, one publicly and one privately owned and operated, are used for ferries plying to the San Juan Islands. The terminal on Capsante Waterway is publicly owned and operated and is used for the receipt of petroleum products, and by small craft in the fishing trade. All of the other terminals are used for general industrial purposes. In addition, there is one oil refinery terminal located to the south of Capsante Waterway that is privately owned and operated and used for handling petroleum products in foreign and domestic trade. Operations and results during fiscal year. New work: Con- struction of two creosoted wood contact pile breakwaters was completed under contract in February 1957 at a cost of $67,679. RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1727 Dredging of the mooring basin under contract was about 77 per- cent completed during the fiscal year, with 175,570 cubic yards of material being removed at a cost of $66,700. Total new work costs of $147,583 included $142,842 Federal funds are $4,741 contributed funds. Maintenance: Maintenance dredging of the channel in Cap- sante Waterway was about 60 percent completed, with 36,880 cubic yards of material being removed at a cost of $20,580. Total maintenance costs during the fiscal year were $22,973. Condition at end of fiscal year. The existing project is about 85 percent complete. Capsante Waterway was completed in 1930, except that portion west of R Avenue, which was omitted at the request of local interests. The project document for the 1954 modification provided, on the basis of surveys completed in 1948, for protection of the mooring basin by construction of a pile break- water 380 feet long, 50 feet east of the basin. At the time of the survey, large log booms moored adjacent to a sawmill south of Capsante Waterway provided ample protection for small-boat moorages north of the waterway from southeasterly storms. However, the mill has since closed, the log booms have been re- moved, and mill operations will probably never be resumed. Therefore, an additional breakwater, 350 feet long, was con- structed southeast of the mooring basin to provide protection formerly obtained by the log booms. The breakwater east of the basin was shortened to 370 feet and relocated to meet new harbor improvements proposed by local interests. Construction of the breakwaters was completed in February 1957. Dredging of the mooring basin is about 77 percent complete. In May 1957, the controlling depth in the portion of Capsante Waterway completed in 1930 was 7.8 feet. Total costs to June 30, 1957, from Federal funds have been $196,094 for new work and $30,942 for maintenance, a total of $227,036. In addition, $27,929 has been expended from con- tributed funds for new work.

SWINOMISH SLOUGH, WASH. Location. This is an inland passage, 11 miles long, between Saratoga Passage and Padilla Bay, in the northwestern part of the State of Washington, about 60 miles north of Seattle. (See U. S. Coast and Geodetic Survey Charts Nos. 6300, 6376, and 6380.) Existing project. This provides for a channel 100 feet wide and 12 feet deep at mean lower low water from deep water in Saratoga Passage to deep water in Padilla Bay, a distance of 11 miles, by dredging and dike construction where necessary. The extreme tidal range is about 19 feet at the south end of the slough and about 16 feet at the north end. The range between mean lower low water and mean higher high water is 11.5 feet at the south end of the slough, 8.5 feet at the north end, and 6.5 feet at La Conner. The actual cost for new work was $409,030. The average annual maintenance cost during the past 5 years was $61,593.

Local cooperation. Under the provisions of the River and Harbor Act of August 30, 1935, adopting the project for the 12- foot channel, local interests were required to furnish free of cost to the United States suitable areas for the disposal of dredged material during initial construction and for future maintenance as and when needed. Compliance with the conditions has not yet been required, as suitable areas for disposal of dredged material have been found without invoking the requirements of local co- operation. RIVERS AND HARBORS--SEATTLE, WASH., DISTRICT 1729 There have been no known non-Federal costs. Terminal facilities. There are 10 wharves on Swinomish slough, all of which are privately owned and operated for industrial pur- poses and not open for general public use. These facilities are considered adequate for existing commerce. Operationsand results during fiscal year. Maintenance dredg- ing was completed by contract in May 1957, 105,147 cubic yards of material being removed at a cost of $70,448. Total costs during the fiscal year were $81,040, all for maintenance. Condition at end of fiscal year. The existing project was com- pleted in 1937. Except for a break in the timber dike at the "Hole-in-the-Wall," the dikes are in good condition. In May 1957, the controlling depth in the channel was 7.5 feet at mean lower low water. The costs to June 30, 1957, have been $409,030 for new work and $1,095,876 for maintenance, a total of $1,504,906.

NEAH BAY, WASH. Location. On the south side of the Strait of Juan de Fuca, 5 miles east of Cape Flattery, at the entrance to the strait from the Pacific Ocean, and about 60 miles west of Port Angeles, Wash. (See U. S. Coast and Geodetic Survey Charts Nos. 6102, 6265, and 6266.) Existing project. This provides for (1) a rubblestone break- water approximately 8,000 feet long between Waada Island and the westerly shore of the bay; and (2) reinforcement of the exist- ing rock revetment extending approximately 2,200 feet west from Baada Point, and about an 800-foot extension of the revetment westward. The tidal range between mean lower low water and mean higher high water is 8.2 feet. The extreme range is 15.5 feet. The actual cost of new work was $2,057,266.

Fully complied with, including provisions of the 1954 River and Harbor Act which require local interests to (a) furnish without cost to the United States, necessary rights-of- 1730 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 way or releases from occupants of Federal lands and any other easements or rights-of-way which may be needed for the work; and (b) agree to hold and save the United States free from damages to non-Federal property that may result from construction and maintenance of the revetment. Formal resolution was adopted by the Crown Zellerbach Corp. on January 6, 1956, granting permission to use their roads for construction, reconstruction, and subsequent maintenance pur- poses and also waiving any claims for damages which may result from construction and maintenance of the project. On November 22, 1955, the Thirteenth Coast Guard District authorized entrance upon the Coast Guard reservation and com- mencement of operations; and on July 24, 1956, formal permit was issued by the Commandant, United States Coast Guard. By letter dated November 28, 1955, the Makah Tribal Council indicated that at its meeting of November 25, 1955, it had approved a request for rights-of-way during construction of revetment and for future maintenance. Resolution No. 37 was adopted by the Makah Indian Tribe on December 12, 1955, giving formal permission to the Corps of Engineers to start the project. On December 16, 1955, the Western Washington Agency of the Bureau of Indian Affairs issued a temporary permit for entrance onto the Makah Reservation; and on December 3, 1956, issued a revocable permit (not to extend beyond November 1, 1965) for the same purpose. There have been no non-Federal costs. Terminal facilities. There are six wharves at Neah Bay, in- cluding two owned by the United States which are used by the Coast Guard, and four privately owned wharves, three of which are open to general public use to accommodate small commercial fishing vessels. In addition to the wharves, there is a facility for dumping and rafting logs. These facilities are considered ade- quate for existing commerce. Operations and results during fiscal year. Contract awarded April 10, 1956, for the revetment work was completed in July 1956. Costs were $3,858, all for new work. Condition at end of fiscal year. The existing project was com- pleted in July 1956. The breakwater was completed in February 1944. In December 1955, the breakwater showed considerable loss of rock from the crest. Work on the revetment authorized by the 1954 River and Harbor Act was completed in July 1956. The project document for the 1954 modification, based on surveys completed in 1948, provides for reinforcement of the exist- ing rock revetment extending 1,800 feet west from Baada Point, an immediate 200-foot extension of the revetment westward, and successive 200-foot extensions at intervals of 2 years, or as needed, for a total extension of 1,200 feet. The total authorized length of the revetment to be reinforced or involved in new construction is therefore approximately 3,000 feet. By 1955, the Coast Guard had extended the revetment to a total length of approximately 2,200 feet, and erosion had progressed to the point where the full RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1731 authorized length was required immediately. Therefore, the re- vetment reinforcement and entire 1,200-foot extension were accomplished at one time. The costs to June 30, 1957, have been $2,057,266 for new work and $174,883 for maintenance, a total of $2,232,149.

EVERETT HARBOR AND SNOHOMISH RIVER, WASH. Location. On Port Gardner Bay, at the northern end of Pos- session Sound, an arm of Puget Sound, 30 miles north of Seattle and 45 miles south of Bellingham. (See U. S. Coast and Geodetic Survey Chart No. 6448.) Previous projects. The original project adopted by the River and Harbor Act of August 18, 1894, provided for a basin in front of the Everett Peninsula, for a channel from the end of the basin around the peninsula to the head of Old River, and for a dike from the lower end of Smith Island to the south end of the basin. By authority of joint resolution of Congress approved April 23, 1902, the work in Old River was discontinued. The project was further modified by the River and Harbor Act of March 3, 1905, to provide for survey of Everett Harbor with a view to the extension of the dike and of the dredged area. For further details, see page 704 of Annual Report for 1905, page 2005 of Annual Report for 1915, and page 1883 of Annual Report for 1938. Existing project. This provides for (1) a training dike extend- ing from a point opposite 23d Street northward to the outlet of Snohomish River, a distance of 12,550 feet, with a spur dike extending 400 feet to the pierhead line from the north end of the main dike; (2) a spur dike extending 1,410 feet westward from Preston Point; (3) removal of an existing section of training dike north of the Snohomish River outlet; (4) a channel 150 to 425 feet wide and 15 feet deep at mean lower low water from deep water in Port Gardner Bay to the 14th Street dock; thence a settling basin 700 feet wide, 1,200 feet long, and 20 feet deep, thence a channel 100 feet wide and 8 feet deep to the outlet of the Snohomish River, a total distance of 2.6 miles; and (5) maintaining East Waterway to a depth of 30 feet at mean lower low water. The extreme tidal range is about 19 feet. The range between mean lower low water and mean higher high water is 11.1 feet. The estimate of cost for new work (July 1957) is $697,000, exclusive of $2,000 United States Coast Guard funds and amounts expended under previous projects. 1732 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 The average annual maintenance cost during the past 5 years was $33,693.

Provisions of the 1954 River and Harbor Act require local interests to (a) furnish without cost to the United States all necessary lands, easements, rights-of-way, and spoil-disposal areas for construction and maintenance of the im- provements, when and as required; (b) hold and save the United States free from damages that may result from construction and maintenance of the improvements; and (c) maintain depths in access channels to the 14th Street mooring basin and to the terminals commensurate with the depth provided in the related project channel. The Port of Everett Harbor Commission, by resolution adopted October 2, 1956, assured the United States that the requirements of local cooperation would be complied with. The Port owns the required right-of-way for the new dike construction, and all real estate interests required for the project have been secured, with right-of-way easement issued by the Port of Everett on March 19, 1957. No rights-of-way are required for the other work items. Terminal facilities. There are 25 wharves and piers on Everett Harbor and Snohomish River-12 are located on Port Gardner Bay, six on the channel to the gap, and seven on Snohomish River. Seven wharves are suitable for use by oceangoing vessels; all of these are located on Port Gardner Bay and East Waterway Chan- nel and one serves a publicly owned and operated general cargo terminal that is open for public use. The remaining wharves are used by barges and light-draft vessels and serve various industrial purposes. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: Con- struction of a spur dike at the upstream limit of the project, con- sisting of a rock-protected gravel fill and timber piling with rock reinforcement, was started in May 1957, by contract. The gravel fill portion, 1,100 feet in length, was completed, using 8,500 cubic yards of gravel and 2,256 tons of riprap. Approximately 350 linear feet of timber piling and 1,361 tons of rock reinforcement were placed riverward of the completed gravel fill. Plans and specifications for widening the existing channel and deepening the existing settling basin were completed. RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1733 Maintenance: Dredging contract was completed in October 1956, with 241,565 cubic yards of material being removed at a cost of $77,300. Costs during the fiscal year were $77,273 for new work and $83,037 for maintenance, a total of $160,310. Condition at end of fiscal year. The existing project is 58 per- cent complete. Dike work was commenced in September 1911, and terminated in September 1912. A 6,000-foot section of the dike was raised to an elevation of 14 feet above mean lower low water in 1931. The channel between the river outlet and the lower harbor was dredged to 8 feet in 1931 and the settling basin to 12 feet in 1940. Dredging of East Waterway has been completed by local interests. Construction of the spur dike is 66 percent com- plete. At the request of local interests, an existing section of training dike north of the Snohomish River outlet will be re- tained, and not removed as previously planned. Dredging of channel and basin will be accomplished with funds available in fiscal year 1958, to complete the project. Controlling depths in October 1956 were 8.2 feet in the channel from the lower harbor to the settling basin, 12.9 feet in the settling basin, 8.2 feet from the settling basin upstream for 5,350 feet, and thence 3 feet to the gap in the dike. Controlling depth in East Waterway in March 1955 was 27.5 feet. The dike was in good condition except for the southerly end. The costs under the existing project to June 30, 1957, have been $403,241 for new work and $440,153 for maintenance, a total of $843,394.

CHIEF JOSEPH DAM, COLUMBIA RIVER, WASH. Location. The Columbia River rises in Columbia Lake, British Columbia, at elevation 2,650, flows northwesterly for nearly 200 miles, then southerly through Upper and Lower Arrow Lakes to enter the United State's near the northeast corner of the State of Washington. From the international boundary the river flows 1734 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 south 112 miles to a point below the mouth of the Spokane River, then west 100 miles to the mouth of the Okanogan River, passing Grand Coulee Dam and Chief Joseph Dam en route. Swinging south, the river follows the eastern foothills of the Cascade Mountains for 209 miles to its confluence with Snake River. A few miles below the Snake, it turns sharply westward and flows for 324 miles, forming the Washington-Oregon bound- ary, to the Pacific Ocean. The works covered by this project are on the Columbia River just upstream from the mouth of Foster Creek, 11/2 miles upstream from the town of Bridgeport, Wash., and 51 miles downstream from Grand Coulee Dam. (U. S. Geological Survey topographic sheet "Okanogan, Wash.," shows the general locality.) Existing project. The project provides for a straight concrete gravity overflow dam on the Columbia River, 220 feet high, for a powerhouse, and an intake of sufficient capacity to utilize future upstream storage. The powerhouse will have 16 units installed initially and a substructure for four additional units. The ulti- mate installed capacity will be dependent upon the rate and amount of future development of upstream storage. Present plans provide for future expansion to a maximum development of 27 units. All units are to be 64,000 kilowatts capacity. The estimate of cost for, new work (July 1957) is $148,000,000 (16 units). The latest (1955) approved estimate for average annual cost of operation and maintenance for a 50-year project life is $1,853,000 for 16 units.

QUILLAYUTE RIVER, WASH. Location. This river is formed by the junction of the Soleduck and Bogachiel Rivers, and flows westerly 5 miles to the Pacific Ocean at La Push, Wash., about 30 miles south of Cape Flattery. (See U. S. Coast and Geodetic Survey Chart No. 6102.) Existing project. This provides for (1) a jetty 15 feet high above mean lower low water on the easterly side of the river mouth, and a dike on the westerly side, with a view of stabilizing the entrance; (2) a channel 10 feet deep and 100 feet wide ex- tending 2,000 feet upstream from deep water; and (3) a basin 10 feet deep, 300 to 425 feet wide, and 2,400 feet long upstream of the channel. The length of the section included in the project is 4,400 feet. The range between mean lower low water and mean higher high water at La Push is 8.3 feet. The extreme range is about 15 feet. The estimated cost for new work (July 1957) is $512,000, exclusive of local contribution of $20,000. The groins authorized with the dike are considered to be inactive, and are excluded from the foregoing cost estimate. The cost of this portion was last revised in 1954, and was estimated to be $12,000. The average annual maintenance cost during the past 5 years was $12,481.

The Quileute Tribal Council granted a permit for dredging and disposal of spoils, removal of rock, and crossing of tribal lands, by resolution adopted August 16, 1956. Easement agreement dated April 4, 1957, with the Quileute Indian Tribe of the Quileute Reservation of Washington gives easement for right-of-way for public highway and right to use thereof for construction and maintenance of the project. On March 7, 1.957, the Port of Port Angeles contributed $20,000 toward cost of the project. Terminal facilities. There are three terminals at La Push, near the mouth of the Quillayute River; of these, two privately owned are open to public use to accomodate small commercial fishing vessels, and one owned by the United States is used as a Coast Guard station. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: Con- tracts awarded in May 1957 for dredging a mooring basin and a channel from Smith Slough to the ocean, and constructing a jetty at the south end of the channel, were continued. The channel was completed by dredging 28,000 cubic yards of material; and ap- proximately 172,000 cubic yards were dredged from the mooring basin, and 2,586 tons of rock were placed in the jetty. Maintenance: Dredging, by contract, was completed in July 1956, with 6,180 cubic yards of material being removed at a cost of $10,537. Emergency repairs to the upstream end of the dike were completed by hired labor in January 1957, by placing ap- proximately 2,000 cubic yards of quarry-run stone. A contract for repairing the remainder of the dike was awarded in May 1957, but no cap rock was placed during the fiscal year. Total costs during the fiscal year were $170,021 for new work and $21,592 for maintenance, a total of $191,613. Condition at end of fiscal year. The existing project is 45 per- cent complete.

The diurnal range of tide is 11.3 feet, and the extreme range is about 19.3 feet. The estimate of cost for new work (July 1957) is $2,200,000, exclusive of $10,000 United States Coast Guard funds. The existing project was authorized by the River and Harbor Act of September 3, 1954. (See H. Doc. 536, 81st Cong., 2d sess., which contains the latest published map.) Local cooperation. Provisions of the 1954 River and Harbor Act require local interests to (a) furnish without cost to the United States all necessary lands, easements, and rights-of-way, and spoil-disposal areas for construction and maintenance of the improvement, when and as required, including provision and maintenance of necessary bulkheads for retention of the spoil; (b) provide and maintain all alterations in utilities, as required; (c) hold and save the United States free from all damages that may result from construction and maintenance of the improve- ment; (d) maintain project depths in the basin areas occupied by boat slips and stalls; and (e) provide, maintain, and operate suitable mooring facilities, including a public landing with supply facilities, utilities, and a parking area, open to all on equal terms. The Port of Seattle Commission, by resolution adopted October 25, 1956, assured the United States that the requirements of 1740 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 local cooperation will be met. Necessary rights-of-way for spoil- disposal areas and bulkheads for retention of spoil were furnished by the Port of Seattle on November 21, 1956. The Port of Seattle has initiated construction of the bulkheads required for retention of dredge spoil. Terminal facilities. There are six pier and wharf facilities in Shilshole Bay, all of which are within the canal entrance below the locks. These are privately owned and are used for servicing and moorage of small craft. (See "Terminal facilities" for Lake Washington Ship Canal.) Operationsand results during fiscal year. Project design, plans and specifications were completed by hired labor. Contractor for the Port of Seattle started construction of disposal area retaining bulkheads in April 1957. Dredging of the boat basin and placing of dredged material in the breakwater section, and placement of gravel filter and armor rock for protection of the dredged fill, were started in April 1957, by contract. Approximately 30 per- cent, or 1,300 linear feet, of the rock breakwater was brought to grade and is ready for placement of armor rock. Placement of rock and gravel was completed in 2,150 feet of the toe sections of the breakwater. Quantities placed in the breakwater during the fiscal year include 57,900 cubic yards of dredged material for the core and 103,273 tons of gravel core, toe, and filter.

Estimated cost for the inactive portion is $28,500 (1954). Terminal facilities. There are 122 wharves and piers on Seattle Harbor, exclusive of those given in the report for Lake Washington Ship Canal. Fifty are located on Elliott Bay, 19 on east waterway, 15 on west waterway, 35 on Duwamish Waterway, and three on Puget Sound near the northern limits of the port. Of these, 20 general cargo terminals and one grain terminal are open for public use. Thirteen of the general cargo terminals are publicly owned and seven of these are publicly operated. The grain terminal is publicly owned and privately operated. The remaining 84 serve various industrial purposes, with the exception of 10 that are either owned or leased by the United States and are restricted to Government use. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance dredg. ing contract was awarded in June 1957, but dredging had not started by the end of the fiscal year. Costs were $3,276, all for maintenance. Condition at end of fiscal year. The existing project was com- pleted in 1931, except the settling basin, which has been classified as inactive. Controlling depths in the Several waterways when last surveyed were as follows: West waterway, 34 feet except RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1745 along the edges and the extreme inner portion in September 1955; East waterway, from Elliott Bay to the Spokane Street terminal, 34 feet except along the edges and except over one small shoal where the least depth was 21.4 feet, and 26.9 feet over a width of 150 feet in the southerly 600 feet of the waterway, in September 1955; Duwamish Waterway, 22.9 feet except along the edges from the head of west waterway to 1st Avenue South, 13.8 feet eycept along the edges from 1st Avenue South to 8th Avenue South, 11.5 feet except along the edges froin 8th Avenue South to 14th Avenue South, and 6.8 feet except along the edges from 14th Avenue South to 5,500 feet above 14th Avenue South; thence 3.1 feet by 150 feet to the turning basin, and a least depth in the turning basin of 0.7 foot in March 1957. Local interests have practically com- pleted dredging of East waterway above the 750-foot section and of the turning basin at the junction of the waterways to 30 feet. The costs from Federal funds to June 30, 1957, have been $170,335 for new work and $908,404 for maintenance, a total of $1,078,739. In addition, $69,333 has been expended from contributed funds for new work.

TACOMA HARBOR, WASH. Location. This harbor is 30 miles south of Seattle and em- braces Commencement Bay and tributary waterways. (See U. S. Coast and Geodetic Survey Chart No. 6407.) Previous projects. The project for the Puyallup Waterway, providing for a channel 500 feet wide, 32 feet deep, and 3,650 feet long, was adopted by the River and Harbor Act of March 3, 1905; suspended by the act of June 25, 1910; and abandoned by the River and Harbor Act of August 30, 1935. For further details, see pages 1372 to 1376 of Annual Report for 1934, and page 1875 of Annual Report for 1938. The project providing for maintenance of a channel in Wapato (Port Industrial) Waterway, 700 feet wide and 34 feet deep over such length as shall have been dredged by local interests to di- mensions stated, was adopted by the River and Harbor Act of August 30, 1935, superseded by the project for that waterway adopted March 2, 1945, and again superseded by the existing 1746 REPORT OF THE CHIEF OF ENGINEERS, U. 8. ARMY,197 project adopted September 3, 1954. For further details, see page 1702 of Annual Report for 1944, and Page 1502 of Annual Report for 1954. Existing project. This provides for (1) a channel in City Waterway, 500 feet wide and 29 feet deep at mean lower low water from deep water in Commencement Bay to the 11th Street Bridge, 500 feet wide and 22 feet deep to the 14th Street Bridge, and varying from 500 to 250 feet wide and 19 feet deep from the 14th Street Bridge to the end of this waterway, a total length of 8,500 feet; (2) a channel in Hylebos Waterway 200 feet wide and 30 feet deep from Commencement Bay to the bend below Lincoln Avenue, thence 150 feet wide and 30 feet deep for about 3,000 feet to the head of the waterway, and a turning basin of the same depth, 410 feet wide and 900 feet average length; (3) construction of two training walls, each about 700 feet long, at the mouth of Puyallup River; and (4) dredging to a depth of 30 feet, Port Industrial (Wapato) Waterway from deep water in Commence- ment Bay to not nearer than 100 feet from Lincoln Avenue, and over widths not nearer than 50 feet from established pierhead lines or lateral limits of the waterway, except through East 11th Street Bridge, where the channel width shall be 150 feet. The extreme tidal range is about 20 feet. The range between mean lower low water and mean higher high water is 11.8 feet.

Disposal areas were furnished by the Port of Tacoma November 19, 1955. In a formal agreement dated February 13, 1956, between the Federal Government and the Port of Tacoma, the Port agreed to comply with the foregoing requirements. The Port has borne one-half the project costs allocable to land enhancement, amounting to $62,700, as required. The Government has reim- bursed the Port for dredging done by the Port in the Federal project area in excess of the contribution for land enhancement. No alterations to utilities have been necessary. Compliance with remaining provisions of the authorizing act is excepted to be obtained. Terminal facilities. There are 74 wharves and piers on Tacoma Harbor. Seventeen are located on Commencement Bay, 27 on City Waterway, four on Middle Waterway, six on Milwaukee Waterway, eight on Port Industrial Waterway, and 12 on Hylebos Waterway. Twenty-eight of the wharves are suitable for use by ocean-going vessels; of these five serving general cargo terminals and one serving a grain elevator are open for public use; two of the former and the latter are publicly owned. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: Con- tract dredging of Port Industrial Waterway, commenced May 4, 1956, was completed in August 1956, with 149,210 cubic yards of material being removed during the fiscal year. Final payment of $34,068 was made to the Port of Tacoma for dredging accom- plished in fiscal years 1955 and 1956 in the project area. Costs were $113,549, all for new work. 'Conditionat end of fiscal year. The existing project was com- pleted in August 1956. City Waterway was completed in 1905. The costs have been $150,019 for new work and $207,310 for maintenance, a total of $357,329, not including $5,000 expended for maintenance from contributed funds. The depths available in February 1957 were as follows: 27.7 feet over a width of 400 feet from Commence- ment. Bay to South 11th Street; 22 feet over a width of 400 feet from South 11th Street to South 14th Street; and 19 feet over a width of 100 feet for 1,200 feet above South 14th Street; thence 16.4 feet over a width of 100 feet to the head of the waterway. Hylebos Waterway was completed in 1939. The costs have been $212,502 for new work and $74,442 for maintenance, a total of $286,944. Depths available in February 1957 were as follows: 28.2 feet over a width of 150 feet from deep water in Commence- ment Bay to East 11th Street; 28.7 feet over a width of 150 feet from East 11th Street to bend below Lincoln Avenue; and 27.6 feet over a width of 150 feet above Lincoln Avenue, with a least depth of 27.7 feet in the turning basin, except in the upper 100 feet and along the edges. The two rubblemound training walls at the mouth of Puyallup River were completed in 1934 at a cost of $51,609, all for new work. Maintenance costs have been $42,720. Total costs to date 1748 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 have been $94,329. On April 4, 1943, a slide destroyed the east training wall. Approximately 550 feet of this wall were replaced by an untreated-contact-pile structure during July 1954, which was soon destroyed by teredo action. Construction of a treated- contact-pile wall to replace the untreated structure was completed in May 1956. Both walls are in good condition. Extension of Port Industrial Waterway was completed in 1956, with about 661,700 cubic yards of material being removed, by contract. The Port of Tacoma dredged about 1,588,000 cubic yards of the Federal project work in the waterway. Total costs to date have been $662,637, all for new work. Miscellaneous inspections and reports have been made at a cost of $2,165, all for maintenance. The total costs under the existing project to June 30, 1957, have been $940,278 for new work, including $51,609 public works funds, but exclusive of $62,700 of value in work contributed by local interests in accordance with their agreement to bear one-half the Port Industrial Waterway project costs allocable to land enhancement; and $326,637 for maintenance, a total of $1,266,915, not including $5,000 contributed funds for maintenance.

GRAYS HARBOR AND CHEHALIS RIVER, WASH. Location. Grays Harbor lies at the mouth of Chehalis River, in the southwestern part of the State of Washington, 45 miles north of the entrance to Columbia River. The inner portion comprises two main channels, the south and the north, connecting the harbor proper with the Chehalis River at Aberdeen. Chehalis River rises in the southwestern part of the State of Washington, about 40 miles east of the Pacific Ocean, flows in a general northwesterly direction and empties into the eastern part of Grays Harbor. (See U. S. Coast and Geodetic Survey Chart No. 6195.) Previous projects: The original project for the Chehalis River, adopted by the River and Harbor Act of August 2, 1882, provided for removal of log jams and. for annual snagging. The original project for the inner harbor, adopted by the River and Harbor Act of July 13, 1892, provided for improvement of north channel, by constructing a dike across middle channel and head of south channel; and improving Chehalis River from Grays Harbor to Montesano by dredging a channel 16 feet deep and 200 feet wide RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1749 and by diking across five sloughs. For further details, see pages 2002-2003 of Annual Report for 1915, and page 1863 of Annual Report for 1938. Existing project. This provides for an entrance channel across the bar 600 feet wide and 30 feet deep, to be secured by a south jetty 13,734 feet long and a north jetty 16,000 feet long, both at an elevation of 16 feet above mean lower low water and by dredging; for maintenance of a channel 30 feet deep at mean lower low water and 350 feet wide from deep water in Grays Harbor to Cow Point, a distance of 14 miles; thence 30 feet deep and 200 feet wide, suit- ably widened at the bends, to a point 13,700 feet upstream from the Union Pacific Railroad bridge at Aberdeen, a distance of 41/8 miles; a turning basin 30 feet deep, 550 feet wide, and 1,000 feet long at the upstream end of the 30-foot channel near Cosmopolis; for a channel 14 feet deep at mean lower low water and 100 feet wide in South Bay to Bay City; for 2 breakwaters at, and mainte- nance of an entrance channel to, Westhaven Cove; and for protec- tion of Point Chehalis for an exposed length of about 7,500 feet. The tidal range between mean lower low water and mean higher high water is 9 feet at Point Chehalis, 9.9 feet at Aberdeen, and 8.1 feet at Montesano. The extreme range is 15 feet at Point Chehalis, 18.1 feet at Aberdeen, and 23.8 feet at Montesano (river flood of 1935). The estimate of cost for new work (July 1957) is $5,223,000, exclusive of $36,000 contributed by local interests and $400 United States Coast Guard funds. The Cosmopolis to Montesano portion of the project (dredging from 12- to 16-foot depth) is classified as inactive, and is excluded from the foregoing cost estimate., The The existing project was authorized by the following: Acts Work authorized Documents and reports June 3, 1896 .

S. ARMY, 1957 cost of the portion was last revised in 1955, and the Federal cost was estimated to be $244,000, with $244,000 to be contributed by local interests. This total cost estimate also does not include amounts expended on previous projects and Navy funds expended on deepening from 26 feet to 30 feet the channel from deep water in Grays Harbor to the Port of Grays Harbor Commission terminal. The average annual maintenance cost during the past 5 years was $278,710. Local cooperation. The River and Harbor Act of July 3, 1930, adopting the 16-foot channel, provides that local interests con- tribute one-half the first cost, estimated at $280,000 (1955), and give assurances satisfactory to the Secretary of War and Chief of Engineers that they will assume the entire cost of maintenance of same and provide a suitable public terminal at Montesano. These assurances have been given and $35,834 contributed, which was expended in 1931 with an equal amount of Government funds in securing a 12-foot channel to Montesano, the remaining contribu- tion necessary to complete the project being deferred until a later date, as approved by the Secretary of War, March 18, 1931. The River and Harbor Act of August 30, 1935, continues the re- quirement that local interests shall pay one-half of the first cost of enlarging the channel between Cosmopolis and Montesano, and further provides that the Grays Harbor Port Commission shall continue to remove all snags and deadheads from the channels, shall furnish free of cost to the United States suitable areas for the disposal of dredged material as and when needed, and shall assist in the work of maintenance by loaning to the United States, when, not required on the work of the Commission, its pipeline dredge without charge other than reimbursement to the Port of Grays Harbor Commission for the operating costs of the dredge on a basis approved by the Chief of Engineers, and maintain the channel above the Union Pacific Railroad bridge at Aberdeen.' These conditions have been met as required to cover current needs. With Navy funds, the 26-foot channel was deepened to 30 feet, and widened to 350 feet in the narrow section, from the port terminal to deep water, at a cost of $162,000. The Act of June 30, 1948, authorizing the Bay City Channel and improvements at Westhaven and Point Chehalis, provides that local interests furnish assurances satisfactory to the Secretary of the Army that they will furnish lands and rights-of-way required for construction and suitable spoil-disposal areas for initial dredg- ing and subsequent maintenance, when and as required; maintain depths at the Bay City wharf commensurate with those of the channel; lend to the United States the port of Grays Harbor dredge for dredging the Bay City and Westhaven Channels, with- out charge other than reimbursement for the operating cost of the dredge on a basis approved by the Chief of Engineers; hold and save the United States free from damages due to construction and maintenance of improvements; enlarge and maintain the West- haven base by dredging; and construct, in accordance with plans approved by the Secretary of the Army, maintain, and operate, SModified by 1954 River andIHarborAct. RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1751 adequate mooring facilities within the basin, utilities, and a public landing with suitable service and supply facilities, open to all on equal terms. The necessary assurances of local cooperation were furnished by the Port Commission of the port of Grays Harbor on October 7, 1949, and were approved by the Secretary of the Army on November 23, 1949. The Port Commission furnished neces- sary rights-of-way on May 1, 1950; and dredged the existing base to a depth of 16 feet and constructed bulkheads, wharf and float facilities, utilities, service and supply features in 1952, thus com- pleting requirements for local cooperation, except for enlarge- ment of the base, which is included in the revised provisions of the 1954 River and Harbor Act. The act of September 3, 1954, authorizing the 30-foot channel to Cosmopolis and the additional breakwater at Westhaven Cove, provides that local interests (a) furnish, without cost to the United States, all necessary lands, easements, rights-of-way, and suitable spoil-disposal areas for initial work and for subsequent maintenance when and as required; (b) hold and save the United States free from damages that may result' from the construction and maintenance of the improvements, including any damages to the three bridges in the Chehalis River improvement area; (c) lend to the United States the port of Grays Harbor pipeline dredge, when not required on necessary work for the port, for initial channel dredging and subsequent maintenance, without charge other than reimbursement for the operation and mainte- nance costs, on a basis approved by the Chief of Engineers; (d) provide and maintain at the proposed project depth, access channels to all active loading wharves and areas along the Chehalis River Channel, and berthing areas within 50 feet of the wharves; (e) continue removal of snags and logs from the entire reach of the main river channel; (f) dredge and maintain a new basin about 16 acres in area shoreward of the Westhaven break- water addition to a depth of at least 14 feet below mean lower low water; (g) construct and maintain any additional bulkheads re- quired in the new basin area for retention of dredged material; and (h) construct, maintain, and operate adequate mooring facilities, utilities, and a public landing with suitable service and supply facilities in the new basin, open to all on equal terms. By resolution dated September 22, 1955, the Port of Grays Harbor Commission accepted the terms as applicable to the 30-foot channel to Cosmopolis and has since complied with all requirements as needed. By resolution adopted September 7, 1956, the Port of Grays Harbor Commission assured the United States, that the local cooperation required for the breakwater addition will be met. The Port owns or controls the necessary lands, and will furnish rights-of-way as needed. The estimated cost of improvements to be provided by local interests is $250,000. A bond issue of $250,000, approved by local voters in 1946, has been reserved for the basin extension that will be protected by the Westhaven breakwater. Terminal facilities. There are 33 wharves and piers on Grays Harbor and adjacent inland waters, including one general cargo 1752 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 terminal, 13 sawmill wharves, 2 pulp- and paper-mill wharves, seven fish wharves; eight miscellaneous industrial wharves, and two are not in use. One general cargo wharf and two fish wharves are publicly owned and open to public use. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work, hired labor: Operations during the fiscal year included.preparation of a general design memorandum for Breakwater C at Westhaven Cove, and engineering studies and investigations for protection of Point Chehalis. Costs were $216, all for new work. New work, contract: A contract for construction of Breakwater C, consisting of 1,350 feet of treated timber piles with rock rein- forcement at Westhaven Cove was awarded in May 1957. The contractor's operations were confined to procurement of ma- terials during the fiscal year. Costs were $17,444, all for new work. A contract for dredging a 30-foot channel and turning basin between Aberdeen and Cosmopolis, commenced in February 1956, was completed in July 1956 by removal of 7,293 cubic yards of material during July. Costs were -$18,977, all for new work. Maintenance, hired labor: Engineering studies were initiated to determine the nature and extent of repairs required for groin 4 at Point Chehalis. The U. S. hopper dredge Pacific, during the periods November 21, 1956, to January 18, 1957, and May 14 to May 31, 1957, removed 366,550 cubic yards, bin measurement, from Sand Island shoal, at a cost of $117,757. The U. S. hopper dredge Biddle, during the period January 16 to March 1, 1957, removed 298,902 cubic yards from Sand Island shoal and 272,160 cubic yards from Cross-Over channel, a total of 571,062 cubic yards, bin measurement, at a cost of $160,419. The pipeline dredge Robert Gray, leased from the Port of Grays Harbor Com- mission, removed 502,318 cubic yards of material from the North Channel at a cost of $71,484. Costs for the fiscal year were -$1,317 for new work and $398,286 for maintenance, a total of $396,969. Condition at end of fiscal year. The existing project was 84 percent complete, excluding the inactive portion. The south jetty was completed in 1902 with a groin 11,952 feet from the high- water line. A 12,656-foot section of the jetty was reconstructed to an elevation of 20 feet above mean lower low water during the period 1936-40. In June 1957, the inner 100 feet of the recon- structed jetty had been partially removed, the next 5,400 feet were at or near grade, the next 500 feet showed subsidence to a maxi- mum depth of 16 feet below grade, and the outer 6,556 feet varied from elevations 4 feet above to elevations below mean lower low water. The north jetty was completed to midtide elevation in December 1913. It was later restored and raised to or above ordinary high water, this work being completed in January 1916. During 1941 and 1942, an 8,288-foot section was reconstructed westward from the high-water line, the inner 7,760 feet being raised to a crest elevation of +20 feet and the remainder to an elevation of +30 feet. The remainder of the north jetty has not RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1753 been restored. The 412-foot section seaward of the reconstructed jetty is at the elevation of -mean lower low water, and the 7,300- foot section shoreward of the reconstructed jetty has sanded in. An examination of the reconstructed jetty, made in June 1957, showed that sea action had leveled the outer 900 feet; had breached the sand spit at the shore end, exposing old jetty rock to the east; and a 4,000-foot section about 1,500 feet from the outer end showed a maximum settlement of 12 feet. In 1950, the Westhaven Cove breakwater authorized by the 1948 River and Harbor Act was completed in two sections, A and B, and four timber-pile groins to protect Point Chehalis were constructed. In 1951, three rock groins were added to the Point Chehalis works. In 1952, the original timber-pile groins were reinforced, and a re- vetment connecting all seven groins was constructed with stone removed from the east end of the reconstructed portion of the south jetty; and local interests completed initial dredging of the entrance channel to Westhaven Cove. In 1953 and 1954, section A of the breakwater and one of the groins were reinforced. Construction of 1,100 linear feet of west shore revetment at Westhaven Cove, extending westward and southward along the shore from groin 5, has been completed. A severe storm in April 1957 damaged extensively the inner- most groin (groin No. 4). With this exception, the Point Chehalis protective works were in good condition. The 26-foot channel previously dredged by the Port of Grays Harbor below Aberdeen was deepened to 30 feet from the port terminal to deep water in the lower harbor in 1945. Deepening of the 26-foot and 18-foot channels to 30 feet, between the port terminal and Cosmopolis, with a turning basin at Cosmopolis of the same depth, was completed in July 1956. The 6-foot channel between Cosmopolis and Montesano, completed in 1910, -was deepened to 12 feet in 1931. The Bay City Channel was completed in July 1950. The controlling depths, when last ascertained, were as follows: Bar channel, 36 feet over a width of 600 feet (September 1956) ; deep water in lower harbor to port terminal, 26 feet over a width of 200 feet (September and October 1956, and April and May 1957) ; port terminal to Cosmopolis, 28.3 feet over a width of 200 feet (June and July 1956); Cosmopolis to Montesano, 8.9 feet (April 1943); and Bay City Channel, 12.4 feet over a width of 100 feet (December 1956). Project dimensions, were available in Westhaven Cove entrance channel in March 1957.

WILLAPA RIVER AND HARBOR AND NASELLE RIVER, WASH. Location. Willapa Harbor consists of the lower reaches of Willapa River and Willapa Bay, an inlet of the Pacific Ocean located about 30 miles north of the mouth of Columbia River in the State of Washington. Willapa River rises about 30 miles east of the harbor, flows in a general westerly direction, and empties into the bay. Naselle River rises in the Willapa Hills southeast of Willapa Bay, flows south and then northwest, and enters the bay near its southerly end, draining an area of 153 square miles. (See U. S. Coast and Geodetic Survey Chart No. 6185.) Previous projects. The original project adopted by the River and Harbor Act of July 13, 1892, provided for a channel 100 feet wide and 8 feet deep from deep water in Willapa Bay to Willapa City, by dredging and construction of dikes across the head of Mailboat and Lauderbach sloughs, and for snagging the Naselle River, The act of August 18, 1894, appropriated funds for the work under way and for improving North River by removal of a log jam. The act of March 3, 1899, authorized additional work in clearing a channel through the log jam on North River and ap- propriated funds for work on the 8-foot channel to Willapa City. The act of June 13, 1902, authorized the expenditure of funds for the improvement of Willapa River and Harbor, North and Naselle Rivers, by snagging or otherwise. The act of March 2, 1907, RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1755 contemplated a channel 150 feet wide and 12 feet deep between South Bend and Raymond. The act of June 25, 1910, provided for a channel 200 feet wide and 18 feet deep from deep water in Willapa Bay to the junction of the North and South Forks of the river at Raymond, and for a channel 18 feet deep and 150 feet wide up the South Fork for a distance of 3,100 feet. For further details, see page 2001 of Annual Report for 1915; page 968 of Annual Report for 1910; and page 1861 of Annual Report for 1938. Existing project. This provides for (1) a channel over the bar at the mouth of Willapa Bay, 26 feet deep at mean lower low water and at least 500 feet wide; (2) a channel 24 feet deep and 200 feet wide from deep water in Willapa Bay to the foot of Ferry Street at South Bend, thence 300 feet wide to the westerly end of the narrows, thence 250 feet wide to the forks of the river at Ray- mond, including a cutoff channel 3,100 feet long at the narrows and a closing dike at Mailboat Slough; (3) a channel 24 feet deep and 150 feet wide up the south fork to the deep basin above Cram lumber mill, and up the north fork to 12th Street, with a turning basin 250 feet wide, 350 feet long, and 24 feet deep at the latter point; (4) a channel 10 feet deep at mean lower low water and 40 feet wide from deep water in Palix River to Bay Center dock, with a widening at the shoreward end to provide a small mooring basin; (5) a mooring basin 15 feet deep, 350 feet wide, and 600 feet long adjacent to the port wharf at Tokeland; (6) an entrance channel at Nahcotta 10 feet deep and 300 feet wide, and a mooring basin 10 feet deep, 500 feet wide, and 1,100 feet long, protected by a rubblemound breakwater about 1,600 feet long; and (7) removal of snags, piles, and other obstructions in the navigable channel of the Naselle River between Naselle and the mouth. The project includes about 26 miles of channel from the entrance through the Willapa River forks, 2,800 feet of the Palix River-Bay Center channel, and 9 miles of the Naselle River upstream of the United States Highway No. 101 bridge. The tidal range between mean lower low water and mean higher high water is 8.9 feet at Toke Point; 9.9 feet at Raymond; 9.2 feet at Bay Center, and 10.8 feet near Naselle. The extreme range is 18 feet at Toke Point; 19.3 feet at Raymond; 16 feet at Bay Center; and 18 feet near Naselle.

ARMY, 1957 The estimated cost for new work (July 1957); is $1,728,000; ex- clusive of $60,000 U. S. Coast Guard funds, of amounts expended on previous projects, and exclusive of $71,775 contributed by local interests. The average annual maintenance cost during the past 5 years was $135,057. Local cooperation. Fully complied with, except provisions .of the 1954 River and Harbor Act, which require local interests to (a) furnish without cost to the United States all necessary lands, easements, rights-of-way, and suitable spoil-disposal areas for initial construction and subsequent maintenance, when and as required; (b) hold and save the United States free from damages due to construction and maintenance of the improvements, in- cluding such damage as may occur to public or leased oyster beds; (c) construct and maintain within each boat basin adequate mooring facilities and a public landing with suitable service and supply facilities open to all on equal terms; (d) construct and maintain the necessary bulkheads for retention of dredged ma- terial at Tokeland; (e) maintain the moorage areas of the boat basins to project depth; and (f) maintain suitable access roads to the boat basins. The Port of Willapa Harbor, by resolution adopted August 14, 1956, and the Port of Peninsula, by resolution adopted November 13, 1956, assured the United States that requirements of local cooperation will be met on Willapa River channel widening, Tokeland boat basin dredging, and Nahcotta dredging and break- water construction. The Port of Ilwaco furnished assurances for the Naselle River snag and pile removal by resolution adopted March 13, 1957. About 95 percent of the disposal areas along the Willapa River have been obtained by the Port of Willapa Harbor, and the remainder will be furnished before start of dredging. Rights-of-way and disposal areas for the two basins are owned or controlled by the respective ports and will be avail- able before the start of dredging. The Port of Willapa Harbor has also initiated planning for bulkheads that will be required at the Tokeland basin. A disposal area for snag removal on the Naselle River has been furnished by local property owners. Terminal facilities. There are 29 wharves on Willapa River and Harbor, including five in Willapa Bay, seven in Bay Center, 15 in Raymond and South Bend, and two in Tokeland. Three of the wharves at Raymond and South Bend are suitable for use by oceangoing vessels; one of these, which is publicly owned and operated, is open for use as a general cargo terminal, and two are located at sawmills. All of the other wharves, including three that are publicly owned and operated, are used by light-draft vessels in local trade. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: Engi- neering and design for Nahcotta breakwater construction and clearing and snagging in Naselle River were completed. Con- tracts were awarded for both projects, but there was no construction activity during the fiscal year. Maintenance: Dredging in Willapa River totaling 40,435 cubic RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 1757 yards, bin measurement, was accomplished by the U. S. hopper dredge Pacific, April 16 to May 13, 1957, at a cost of $74,685. The U. S. hopper dredge Rossell removed 180,477 cubic yards from Willapa River and 21,567 cubic yards from Willapa Bar, for a total of 202,004 cubic yards, bin measurement, May 17 to June 17, 1957, at a cost of $52,178. Costs during the fiscal year were $15,906 for new work and $160,256 for maintenance, a total of $176,162. Condition at end of fiscal year. The existing project is about 46 percent complete. The entrance and Willapa River channels were completed in 1936, except for the widening. The channel from Palix River to Bay Center was completed in 1949. Work re- maining to be done to complete the project consists of the features authorized by the 1954 River and Harbor Act, including the Willapa River widening, the Tokeland and Nahcotta boat basins, and the Naselle River improvement. Engineering work is 49 percent complete; and contracts have been awarded for Nahcotta breakwater construction, and clearing and snagging in Naselle River.

The Kootenai River rises in British Columbia, flows southerly about 40 miles into Montana and thence northwesterly across western Montana and the northeastern corner of Idaho to reenter British Columbia, where it empties into Columbia River after passing through Kootenay Lake. Libby Dam will be located on the Kootenai River, 15 miles upstream from Libby, Montana, and 217.0 miles upstream from its confluence with the Columbia River. (See U. S. Geological Survey topographic sheet, "Thompson Lakes, Mont.") Existing project. The project provides for a straight concrete gravity overflow flood control and power dam on Kootenai River about 400 feet high; for a powerhouse; and for a reservoir backing water into Canada with a usable storage capacity of 5,010,000 acre-feet. The initial power installation will consist of six units, each unit with a capacity of 100,000 kilowatts. Construction of the dam will depend on an order to be issued by the International Joint Commission. The estimate of cost for new work (July 1957) is $285,000,000 (6 units). The existing project was authorized by the Flood Control Act of May 17, 1950. (See H. Doc. 531, 81st Cong., 2d sess., which contains the latest published map.) Local cooperation. None required. Operations and results during fiscal year. Preliminary engi- neering studies were continued on final location of axis, and type and layout of dam. Costs were $3,651, all for new work. FLOOD CONTROL--SEATTLE, WASH., DISTRICT 1761 Condition at end of fiscal year. No construction work has been done. Preliminary engineering is about 26 percent complete. The general location of the dam has been fixed near Dunn Creek above the Fisher River. Discussions have been held with Great Northern Railway, United States Forest Service, Montana State Highway Department, J. Neils Lumber Co., and Zonolite Mine Co. on relocation problems. The project as a whole is about 2 percent complete. Costs to June 30, 1957, have been $513,121, all for new work.

LIGHTNING CREEK, CLARK FORK, COLUMBIA RIVER BASIN, IDAHO Location. Lightning Creek rises in the Cabinet Mountains in northeastern Idaho and flows south 20 miles to join Clark Fork 4 miles upstream from Pend Oreille Lake. The town of Clark Fork, 65 miles northeast of Spokane, Washington, is situated near the mouth of Lightning Creek. (See U. S. Geological Survey quadrangle, "Priest Lake, Idaho-Mont.") Existing project. The plan of improvement provides for a rip- rapped levee 3,700 feet long on the left bank of Lightning Creek near its mouth so as to prevent diversions of the stream during floods through the town of Clark Fork. The estimated cost of the project is $87,000 (July 1957). The existing project was authorized under the Columbia River Basin Plan by the Flood Control Act approved May 17, 1950. (See H. Doc. 531, 81st Cong., 2d sess., which contains the latest published map.) Local cooperation. Section 3 of the Flood Control Act approved June 22, 1936, as amended, applies. Assurances of cooperation were received from the Village of Clark Fork in a letter dated February 25, 1950, as follows: The Village of Clark Fork assumes responsibility for constant patrolling of the levee during floods and immediate repairs of damage caused by debris; will maintain the structure to the same height and in the same condition as exists on the date the completed project is turned over to local interests, and will remove all debris accumulations against or near the levee that may reduce its effectiveness; and will make any change in the water-supply line deemed, desirable or necessary by local interests in connection with the project. 1762 REPORT OF THE CHIEF OF ENGINEERS, U.

ALBENI FALLS RESERVOIR, PEND OREILLE RIVER, IDAHO Location. Pend Oreille River has its source in Pend Oreille Lake in northern Idaho, which receives most of its inflow from Clark Fork. The lake has an area of about 83,500 acres. Pend Oreille River leaves the lake near Sandpoint, Idaho, and flows westerly 25 miles to Albeni Falls, where the channel is divided by an island and the low water fall is about 7 feet. About 2 miles downstream from the falls, the stream enters the State of Wash- ington, in which its course is northwesterly for 72 miles to the Canadian border. In Canada, Pend Oreille River flows westerly for 16 miles and joins the Columbia River. Just downstream from this junction, Columbia River enters the United States, where it flows generally southward across Washington and westerly along the Washington-Oregon line to the Pacific Ocean, a total distance of about 748 miles. (See U. S. Geological Survey topographic sheets "Sandpoint, Idaho," and "Newport, Wash.") Existing project. The project provides for a low concrete- gravity dam at Albeni Falls on Pend Oreille River for power gen- eration, flood control, and related water uses. The dam consists of a gated, open-channel spillway in the left channel and a power- house having an installation of 42,600 kilowatts in the right chan- nel, creating a reservoir with a usable storage capacity of 1,153,000 acre-feet. The dam site is 838 and 90 miles upstream from the mouths of Columbia and Pend Oreille Rivers, respectively, and is 50 miles northeast of Spokane, Wash. The actual cost for new work was $30,260,951. The latest (1955) approved estimate for annual cost of maintenance is $345,000. The existing project was authorized by the Flood Control Act of May 17, 1950. (See S. Doc. 9, 81st Cong., 1st sess., which contains the latest published map.) FLOOD CONTROL--SEATTLE, WASH., DISTRICT 1763 Local cooperation. None required. Operations and results during fiscal year. Operation and main- tenance, hired labor. The reservoir was operated through its fifth annual cycle of storage and release during the year. The highest pool level attained was elevation 2062.50 on September 9, 1957; the lowest was elevation 2054.76 on April 22, 1957. Maxi- mum storage used was 710,000 acre-feet. There was a flood surcharge of 0.5 foot during the year. The log chute was operated to pass 71 rafts, constituting 22,961 tons or 6,123,000 board feet of logs, through the dam for processing by mills downstream. Routine structural, mechanical, and electrical maintenance was performed on the spillway dam and equipment, and on those features of the powerhouse that were completed and operating. Drift disposal was conducted during the fall and winter, and drift collection operations were conducted during spring high water, with log boom facilities at three sites at the mouth of Clark Fork. New work, hired labor: Planning was continued for protective and restoration works required by reservoir effects on railroads, highways, municipal, and utility properties. Acquisition of land rights for the reservoir was continued. New work, contract: Modifications to the drift collection facili- ties at the mouth of Clark Fork were accomplished. Bank protec- tion works involving placement of 55,000 cubic yards of rock on properties damaged by reservoir operation were constructed. The costs during the fiscal year were $342,779 for new work and $243,624 for maintenance, a total of $586,403. Condition at end of fiscal year. Construction of the existing project was started in January 1951, and is substantially complete. Construction of the spillway dam and powerhouse cofferdams was completed in June 1952. The project started operations in June 1952, impounding storage which was used to increase minimum flows through downstream power plants during the extremely low water-supply period of that fall. Construction of the power- house and intake structure was started in March 1952 and com- pleted in October 1954. Installation of powerhouse equipment was started in July 1953 and completed in August 1955, with three generating units in commercial operation. Engineering and de- sign of powerhouse operating equipment and machinery are com- plete. Evaluation of reservoir effects on the kokanee fishery and erosion of vulnerable public and private properties is continuing. Negotiations are proceeding with a view to restoring or protect- ing the properties so far as legally required. Terms of a contract with the State of Idaho for construction of facilities for produc- tion of kokanee fry that may be destroyed by operation of the proiect have been completed and are ready for signature. Work remaining to be done to complete the project includes additional modification of drift-control facilities to prevent damage from ice, and restoration or protection of additional reser- voir properties so far as legally required. Kokanee fish produc- tion facilities will be constructed by the State of Idaho and reim- bursed by the Government and other responsible parties. Re- maining land acquisition includes operating railroad and State 1764 PEPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 highway tracts, which are not to be acquired pending determina- tion regarding damages to operating properties and alteration of facilities, if required. New tracts have been authorized for acquisition to correct an erosion problem, and negotiations for these additional areas are in progress. The costs to June 30, 1957, have been $30,260,951 for new work and $548,630 for maintenance, a total of $30,809,581.

Location. Stillaguamish River is formed by the confluence of its north and south forks at Arlington, Wash., and flows westerly a distance of 22 miles to Puget Sound, entering Port Susan through Hat Slough and South Pass, and Skagit Bay through West Pass. (See U. S. Coast and Geodetic Survey Chart No. 6450, and U. S. Geological Survey quadrangles Stanwood, Marysville, and Stillaguamish, Wash.) Existing project. The plan of improvement provides for works to reduce bank erosion and channel changes on Stillaguamish River between Arlington and the head of Hat Slough, a distance of 15 miles, and on Cook Slough, 3 miles long, as follows: Revet- ment at 26 places on the river and Cook Slough; a concrete weir 275 feet long between steep sheet pile piers at the head of Cook Slough to limit flow through the slough; and two cutoff channels, each about 900 feet long, to eliminate sharp bends in Cook Slough. Tidal influence extends about 3 miles into the improved section. Flood stages of 16 feet above low water at the Cook Slough weir have been observed. The actual cost for new work was $220,594. The average annual maintenance cost during the past 5 years was $22,747. The project was authorized by the Flood Control Act approved June 22, 1936 (H. Doc. 657, 71st Cong., 3d sess.). This document contains the latest published map of the locality. Local cooperation. Fully complied with. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $5,000 (1937 price level). Operations and results during fiscal year. Revetment repairs by contract, commenced in June 1956, were completed in July FLOOD CONTROL--SEATTLE, WASH., DISTRICT 1765 1956. Repairs were made on an emergency basis with County equipment in December 1956. Additional contract repairs were made in May 1957. Total costs, including condition and operation studies, were $19,520, all for maintenance. Condition at end of fiscal year. The existing project was com- pleted in 1939. Progressive deterioration of revetments necessi- tates annual repair at critical points. Other features are in good condition. The costs to June 30, 1957, have been $134,595 from regular funds and $85,999 from emergency relief funds, a total of $220,594, for new work; and $205,068 for maintenance, a total of $425,662.

EAGLE GORGE RESERVOIR, GREEN RIVER, WASH. Location. Green River lies wholly in King County, Wash. From its source at the crest of the Cascade Mountains in the vicinity of Stampede Pass, the river flows westerly for 40 miles to Auburn, thence northerly 32 miles to its mouth in Elliott Bay, which forms the principal part of Seattle's salt-water harbor. Eagle George dam site is on the upper Green River, 6 miles south- east of Kanaskat, Wash., and 1 mile downstream from the mouth of North Fork. (See U. S. Geological Survey topographic sheet, "Cedar Lake quadrangle, Wash.") Existing project. The project provides for a rockfill dam about 235 feet high, with a gated spillway having a concrete weir at elevation 1176 feet above mean sea level and top of gates at elevation 1206, to create a reservoir with a capacity of 106,000 acre-feet. The length along the top of the dam is approximately 700 feet; at the bottom, 100 feet. The improvement is designed to control flooding in the Green River Valley to prevent existing agricultural and urban flood damage, and to make possible further expansion of the Seattle industrial area. The estimate of cost for new work (July 1957) is $27,700,000, exclusive of local contribution of $2,000,000. The approved estimate for average annual cost of maintenance and operation for a 50-year project life is $80,000. The existing project was authorized by the Flood Control Act of May 17, 1950. (See H. Doc. 271, 81st Cong., 1st sess., which contains the latest published map.) Local cooperation. Fully complied with. Total actual costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $2,000,000. 1766 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,,1957 Operations and results during fiscal year. New work, hired labor. Acquisition or right of entry was obtained on lands re- quired for utility relocations and dam construction. Final plans and specifications for relocation of railway station facilities were 90 percent completed. Plans and specifications for the dam, ad- ministrative and operational buildings, and site access were com- pleted and bids opened on May 10, 1957. All bids were rejected. Preliminary engineering studies were completed for fireproofing and protection of Chicago, Milwaukee, St. Paul and Pacific Rail- road Co. bridge No. FF-706, and city of Tacoma waterline cross- ing. Design memoranda issued during the fiscal year included: Concrete aggregate investigation, report on necessity for reloca- tion of county roads Nos. 1224, 381, and 191, King County, Wash.; real estate memoranda for third and fourth sections of railroad re- location, dam construction and borrow areas; and reservoir area and cemetery. New work, contract: Major construction on Northern Pacific Railway relocation continued between miles 70.2 and 74.6. Con- tinuing contracts were awarded on the remaining railroad reloca- tion between miles 74.6 and 84.2, and the relocation of public and private roads. Work on this section included logging and cold- decking of merchantable timber, clearing, grading, drainage, and construction of piers, abutments, and approach fills on three major bridges. Work accomplished under the relocation agreement with the Northern Pacific Railway Co. included protection of existing facilities and initial delivery of track, signal, and communication line materials. Relocation of the Rock Island-Renton 110-kilovolt transmission line was essentially completed under the contract with Puget Sound Power and Light Co. Temporary relocation of five short sections of Pacific Telephone and Telegraph Co. lines was completed under the terms of a relocation contract to protect the lines during relocation of the railroad. The city of Tacoma's 100-million-gallon McMillan reservoir was completed and placed in operation under the terms of an agreement which provides, in part, that the Government is to pay the interest, depreciation, operation, and maintenance costs for a 3-year period for use of the reservoir. These costs are programed under construction facilities. Costs during the fiscal year were $3,945,112 from Federal funds and $1,500,000 from contributed funds, a total of $5,445,112, all for new work. Condition at end of fiscal year. The project as a whole is about 26 percent complete. Relocation of Northern Pacific Railway subgrade is about 33 percent complete. The track, to be laid by the Northern Pacific Railway Co., will be ready for train opera- tion in the fall of 1958. Relocation of Puget Sound Power and Light Co.'s Rock Island-Renton 110-kilovolt transmission line has been completed except for removal of temporary lines following completion of subgrade work on railroad relocation. Temporary relocation of Pacific Telephone and Telegraph Co. lines has been completed except as required for the fourth railroad relocation contract. No construction on the dam has been started. On the FLOOD CONTROL--SEATTLE, WASH., DISTRICT 1767 basis of present schedules and adequate funding, the project will be ready for beneficial use by October 1960. .Engineering on the entire project is 93 percent complete. De- sign memoranda, plans, and specifications for project features to be completed include: Relocation of U. S. Forest Service roads, alterations to Chicago, Milwaukee, St. Paul and Pacific Railroad bridge, reservoir clearing, and reservoir regulation and operations manual. Plans and specifications necessary to complete the rail- way relocation include Northern Pacific Railway Station facili- ties, production of top ballast, and foundations-for alterations to Chicago, Milwaukee, St. Paul and Pacific Railroad bridge. Nego- tiations for a contract with city of Tacoma are continuing for encasement of the city's water line where it crosses the relocated railroad. The city of Tacoma will construct the water line pro- tection facilities. Negotiations for permanent relocation of Pacific Telephone and Telegraph Co. facilities in the railroad construction and reservoir areas are yet to be accomplished. Plans and speci- fications for the rockfill dam, administrative and operational build- ings, and site access are being revised prior to readvertising. Costs to June 30, 1957, have been $5,596,312 from Federal funds and $2,000,000 from contributed funds, a total of $7,596,312, all for new work.

TACOMA, PUYALLUP RIVER, WASH. Location. The Puyallup River has its source in the glaciers on the western slopes of Mount Rainier in the State of Washington, flows northwesterly 50 miles, and empties into Commencement Bay, an arm of Puget Sound, at Tacoma, Wash. The work 1768 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 covered by this project is on Puyallup River, within the city limits of Tacoma. (See U. S. Coast and Geodetic Survey Chart No. 6407.) Existing project. The plan of improvement provides for a channel with a capacity of 50,000 second-feet between the East 11th Street Bridge and the lower end of the intercounty improve- ment, a distance of about 2.2 miles, by straightening the channel, building levees, revetting the channel and levees, and making all necessary bridge changes. The 11th Street- Bridge at the lower end of the project- is 0.75 mile above the mouth of the Puyallup River. The diurnal tidal range at the mouth of the river is 11.8 feet and the extreme range is 20 feet. The improvement was planned in conjunction with Mud Mountain Dam and affords pro- tection against floods about 50 percent greater than the maximum discharge of record. The actual cost for new work was $3,942,818. The average annual maintenance cost during the past 5 years was $2,234. The project was authorized by the Flood Control Act approved June 22, 1936. (See Senate committee print, "Puyallup River, Wash.," 74th Cong., 2d sess.) Local cooperation. None required. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. Removal of brush from revetments, commenced by hired labor in June 1956, was completed in November 1956. A contract for poison spraying of brush was awarded in June 1957, but no work had been done before the end of the fiscal year. Repair of revetments by con- tract, commenced in June 1957, was 98 percent complete. The costs, all for maintenance, were $2,524. Condition at end of fiscal year. The existing project was com- pleted in 1950. Reconstruction of six bridges, channel improve- ment, and levee construction were completed in 1949. Placing of additional riprap was completed in May 1950. In June 1957, all features were in good condition, except for minor revetment sloughs, and a light growth of brush.

MUD MOUNTAIN RESERVOIR, WHITE RIVER, WASH. Location. The White River rises on the northeastern slope of Mount Rainier, in the State of Washington, and flows in a general northwesterly direction for 57 miles to its confluence with the FLOOD CONTROL-SEATTLE, WASH., DISTRICT 1769 Puyallup River. The White River is the principal tributary of the Puyallup River and enters the latter 10 miles above its mouth in Puget Sound at Tacoma, Wash. The works covered by this project are on White River near Mud Mountain, 6 miles southeast of Enumclaw, Wash. (See U. S. Geological Survey topographic sheet "Cedar Lake quadrangle, Washington."). Existing project. The plan of improvement provides for the construction of a rockfill dam, 700 feet long at crest elevation and rising 425 feet above bedrock. The dam is located 28 miles above the confluence of the White and Puyallup Rivers and 38 miles above the mouth of the Puyallup River. The reservoir has a storage capacity of approximately 106,000 acre-feet. Outlet works are located in the right abutment and permit controlled discharge of 17,700 cubic feet per second through two concrete-lined tun- nels, with uncontrolled discharge over a spillway having a maxi- mum capacity of 139,000 cubic feet per second. The improvement affords flood protection to the White and Puyallup River Valleys and protects the Tacoma industrial district in conjunction with the authorized project at that locality against floods about 50 percent greater than the maximum discharge of record. The existing project was authorized by the Flood Control Act approved June 22, 1936. (See Senate committee print, "Puyallup River, Wash.," 74th Cong., 2d sess.) The actual cost for new work was $13,208,063. The average annual maintenance cost during the past 5 years was $87,129. Local cooperation. None required. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operationsand results during fiscal year. Operation and main- tenance of the dam and appurtenances, gages, ratio network, roads, buildings, grounds, and utilities were continued; and drift re- moval, fish haul, and miscellaneous studies were accomplished. Repairs to the lower portals access trestle were accomplished. Installation of one temporary weir on the right bank below the dam was completed in June 1957. A 30,000-gallon water tank built during original dam construction was razed in June 1957. A total of 4,610 migratory fish was transported around the dam in tank trucks. There were no severe floods during the year, the highest pool level attained attributable to floods being elevation 1065 in December 1956, equivalent to a head of 170 feet and a storage of 16,000 acre-feet. In June 1957, the pool was raised to elevation 1060 for State Department of Fisheries experiments; and further raised to elevation 1100 to assist Puget Sound Power and Light Co., who had their diversion works shut down for repairs. Costs for the fiscal year were $94,009, all for maintenance. Condition at end of fiscal year. The existing project was com- pleted in June 1953. The costs to June 30, 1957, have been $13,182,063 from regular funds and $26,000 from emergency relief funds, a total of $13,208,063, for new work; and $1,183,095 for maintenance, a combined total of $14,391,158. 1770 REPORT OF THE CHIEF OF ENGINEERS, U.

Previous projects. Prior to the Act of June 13, 1902, the im- provement of Snake River below Lewiston, Idaho, (River Mile 140), was associated with improvement of Columbia River above Celilo Falls. The total cost and expenditure prior to adoption of a formal project was $168,500, of which $153,410.26 was for new work and $15,089.74 was for maintenance. For further details see page 1991 of Annual Report for 1915. 1773 1774 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Open-river improvement of Snake River from Riparia, Wash. (River Mile 67) to Pittsburgh Landing (River Mile 218) was authorized by Act of June 13, 1902 (H. Doc. 126, 56th Cong., 2d sess.), with no specified channel dimensions above Lewiston. For further details, see page 2246 of Annual Report for 1903 and page 1986 of Annual Report for 1906. This authorization was extended to include improvement from the mouth to Riparia by Act of June 25, 1910 (H. Doc. 411, 55th Cong., 2d sess.), and was further ex- tended to include the reach from Pittsburgh Landing (River Mile 218) to Johnson Bar Landing (River Mile 231) by Act of August 30, 1935. (Rivers and Harbors Committee Doc. 25, 75th Cong., 1st sess.) Under these authorizations the total cost and ex- penditure for improvement below Lewiston, Idaho was $418,219.88, of which $246,739.54 was for new work and $171,480.34 was for maintenance.

ICE HARBOR LOCK AND DAM, SNAKE RIVER, WASH. Location. The site of this project is on the Snake River, 9.7 miles above the mouth of the river, at the head of the McNary lock and dam pool, and 12 miles east of Pasco, Wash. 1776 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957: Existing project. The project provides for a dam, powerplant, navigation lock and appurtenant facilities. The improvement will provide for navigation, hydroelectric power generation and incidental irrigation. The dam is designed for a normal pool at elevation 440 mean sea level. The normal pool will create a reservoir extending upstream about 35 miles, providing slack- water to the Lower Monumental lock and dam site. The total length of the structure will be approximately 2,790 feet, and will consist of a nonoverflow section at the south abutment, power- house, spillway dam, nonoverflow section, navigation lock and an earthfill and rockfill at the north abutment. Fish passing facili- ties including two ladders will be provided. The powerplant will be constructed for three 90,000 kilowatt units to be installed initially with provision for 3 additional units, an ultimate total of 6 units. The spillway dam will be 610 feet long, and the over- flow crest at elevation 391 mean sea level will be surmounted by 10 radial gates 50 feet wide by 52.9 feet high which will provide capacity to pass a spillway design flood of 850,000 cubic feet per second. The deck will be at elevation 453 mean sea level and will provide a service road and track for a gantry crane. The navigation lock is a single lift type and will have clear plane dimensions of 86 feet by 675 feet. The estimate of cost for new work approved in 1955 is $135,000,000. The existing project was authorized by the River and Harbor Act approved March 2, 1945. (See H. Doc. 704, 75th Cong., 3d sess.) Operations and results during fiscal year. New work: The grading and surfacing of both the south and north shore access roads to the project were completed. Construction of the first- step cofferdam, unloading spur track, temporary fish ladder, resi- dent engineer's office building were completed during the year. A contract was awarded and construction is on schedule for the first major phase of the project within the first-step cofferdam; con- sisting of 71/2 bays of the spillway dam, skeleton powerhouse structure, concrete gravity south abutment section, and the south shore fish ladder. Contracts were awarded and construction is under way for relocation of the Spokane, Portland and Seattle Railway past the dam site and the construction of a permanent water supply system for the project. Supply contracts were awarded for the powerhouse intake gantry crane, tailrace gantry crane, and the 500-ton powerhouse bridge crane. Land acquisition for the project site lands and rights-of-way were completed during the year and acquisition continued for reservoir lands and reloca- tions. Engineering design studies for the first phase of construc- tion were completed during the year and are well underway on the second and third construction phases of the project and utility relocations. Hydraulic model studies were carried on in con- junction with the design studies for the south shore first phase construction work. Total costs during the fiscal year were $10,130,947, all for new work. RIVERS AND HARBORS-WALLA WALLA, WASH., DIST. 1777 Condition at end of fiscal year.

McNARY LOCK AND DAM, COLUMBIA RIVER, OREG. Location. The site of this project is on the Columbia River, 292 miles above the mouth, near Umatilla, Oreg., and 3 miles above the mouth of the Umatilla River. Existing project. This project provides for a dam, powerplant, navigation lock for power, navigation and incidental irrigation. The dam which raises the normal water surface approximately 85 feet to elevation 340 mean sea level is approximately 7,300 feet long and consists of an earthfill and rockfill dam at the Oregon (south) abutment, powerhouse, spillway dam, navigation lock and earthfill and rockfill dam at the Washington (north) abut- ment. The powerhouse has an installation of 14 units of 70,000 kilowatts each, totalling 980,000 kilowatts. The spillway dam is 1,310 feet long, and the overflow crest at 291 feet above sea level is surmounted by 22 vertical-lift gates placed between piers which extend to elevation 361 mean sea level where a service roadway permits the operation of two 200-ton gantry cranes for regulating the gates. The navigation lock is a single lift type, capable of operating at all flows less than 800,000 cubic feet per second. Facilities for the upstream migration of fish consist of two fish ladders, a lock and an elevator. All structures are founded on a massive basalt flow that reaches a maximum thickness of 130 feet and directly overlies a sedimentary interbed. The pool created by the dam provides a navigable channel with a depth of 12 feet or over between the dam and the confluence of the Yakima River, a distance of approximately 48 miles. A controlling depth of 9 feet will be provided on Snake River from its mouth to a point approximately 10.2 miles above the mouth. 1778 REPORT OF THE CHIEF OF ENGINEERS, U. S.

JOHN DAY LOCK AND DAM, COLUMBIA RIVER, WASH. AND OREG. Location. The site of this project is on Columbia River, about 3 miles downstream from the mouth of John Day River and about 215 miles above the mouth of Columbia River. Existing project. The project was originally authorized by the Flood Control Act approved May 17, 1950, in accordance with the plan presented in House Document 531, 81st Congress, 2d session, to provide for a dam, power plant, navigation lock and appurtenant facilities, with a slackwater pool about 75 miles long extending to McNary Lock and Dam. Under this plan the project would pro- vide 2,000,000 acre-feet of surcharge storage space between normal pool elevation 255 and elevation 292 for control of floods on Colum- bia River. The powerhouse would provide 13 generating units of 85,000 kilowatts each for a total initial installed capacity of 1,105,000 kilowatts. Subsequent to project authorization noted above, a review of the flood control features of John Day Dam was authorized by resolu- tion of the Senate Committee on Public Works dated April 22, 1953. This review, dated March 25, 1955 and revised December 14, 1955, determined that the originally proposed pool fluctuation between elevations 255 and 292 would unduly handicap present and future developments bordering John Day pool. It recommended adoption of normal pool at about elevation 262 with about 500,000 acre-feet of flood storage space to be obtained between proposed drawdown level at elevation 252 and maximum controlled pool at elevation 265. Other features of the project would remain 1780 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 essentially unchanged. The Review Report was approved by the Board of Engineers for Rivers and Harbors on January 19, 1956, and submitted to the Congress August 9, 1956, where it was ordered to be printed as Senate Document 10, 85th Congress, 1st session. The revised project proposed in the Review Report is economi- cally feasible to a slightly greater degree than the project as originally authorized. In addition it has the firm support of local interests, whereas the original proposal is strongly opposed. Also, planning funds appropriated in fiscal years 1956 and 1957 were based on continuation of studies using pools and storage recom- mended in Review Report. In view of this situation and con- tingent upon indicated approval of the Public Works Committees of Congress, the Review Report plan is considered to represent the presently authorized project. Funds available for advance engineering for fiscal year 1956 were used in further development of the Review Report plan, and a Site Selection Report was prepared under date of June 15, 1956. Funds available for advance engineering for fiscal year 1957 were used for general design memorandum studies. In accordance therewith, a normal pool level at elevation 265 now appears to be most economical with flood-control storage space in the amount of 500,000 acre-feet available between elevations 257 and 268. The project would include a single-lift navigation lock 86 feet wide by 675 feet long, in clear dimensions, with a normal lift of 105 feet; spillway, with twenty 50 x 58-foot gates, would be designed to pass a flood of 2,250,000 c.f.s. at maximum pool elevation 276 above mean sea level; and fish ladders and other facilities as necessary would be provided for passage of migratory fish. Power facilities to be provided initially and the extent of provisions for future power installation have not yet been determined and are subject to results of continuing general design memorandum studies. It is likely, however, that the initial power installation will consist of at least 12 units at 109,000 kilowatts each for a total of 1,308,000 kilowatts. The estimated cost of new work approved in 1956 is $350,000,000. Operationsand results during fiscal year. New work: Design Memorandum No. 1, "Hydrology," which was 95 percent complete at the end of fiscal year 1956, was completed. General design memorandum studies were continued following completion of De- sign Memorandum No. 2, "Site Selection Report, John Day Lock and Dam, Columbia River, Oreg. and Wash.," dated June 15, 1956. These studies included surveys, foundation drilling, construction of a hydraulic model, and office engineering studies. The general design memorandum was 70 percent complete at the end of the fiscal year. Total costs during the fiscal year were $1,349,345, all for new work. Condition at end of fiscal year. Construction has not been initiated. Planning prior to initiation of construction is 75 per- cent complete, based on authorization in accordance with the RIVERS AND HARBORS-WALLA WALLA, WASH., DIST. 1781 general plan contained in Senate Document 10, 85th Congress, 1st session.

COLUMBIA RIVER AND TRIBUTARIES ABOVE CELILO FALLS TO KENNEWICK, WASH. Location. This project includes improvement of 128 miles of the Columbia River between the head of Celilo Falls and Kenne- wick, Wash. (See U. S. Geological Survey Map of Washington.) Previous project. The original project was adopted by the River and Harbor Act of June 10, 1872, and modified by the River and Harbor Act of March 2, 1907. For further details, see page 1992 of Annual Report for 1915; page 1889, Annual Report for 1931; and page 1845, Annual Report for 1938. Existing project. This provides for a channel 7 feet deep and 150 feet wide at low water from Celilo Falls to Wallula, with no specified depth or width between Wallula and the mouth of the Snake River and for an approach channel 6 feet deep at low water from the navigation channel in the Columbia River to the site of port development at Arlington, Oreg. The actual cost for new work exclusive of amounts expended on the previous project was $1,356,584. The average annual maintenance cost during the past 5 years was $13,743. The incompleted channel rectification work at Owyhee Rapids, Squally Hook and at Indian Rapids, is classified as inactive and is excluded from the foregoing cost estimate. The cost of this portion revised in 1954 is estimated to be $419,000.

ARMY, 1957 Local cooperation. The River and Harbor Act approved March 2, 1945, provides that for the Arlington Channel, local interests give assurances that they will construct a suitable freight termi- nal, open to all on equal terms. These assurances were approved December 29, 1947, but a suitable freight terminal has not been constructed. Terminal facilities. There is one public dock and terminal on this stretch of river located at Pasco, Wash. (mile 127.2 above Celilo), and owned by the port of Pasco. Located adjacent to the wharf are the following: (a) A bulk grain elevator of 500,000- bushel capacity, and served by rail, water, and truck transporta- tion. Within the structure is a warehouse for handling general cargo. (b) Storage facilities for a total of 11,000,000 gallons of petroleum products, 10,000,000 of which are served by rail, water, truck, and pipeline transportation, the remaining 1,000,000 gallons being served by water and truck only. Privately owned storage facilities for handling waterborne commerce with capacities and locations are as follows: A bulk grain elevator of 2,000,000-bushel capacity, with rail, truck, and water connections is located at Kennewick, Wash. (mile 127.1 above Celilo) ; a 300,000-bushel capacity grain elevator at Arling- ton, Oreg. (mile 40.8 above Celilo) ; and a 335,000-bushel elevator at Umatilla, Oreg. (mile 88.2 above Celilo). Other facilities for handling bulk grain from truck to river craft, but without rail connections are as follows: A bulk grain elevator of 400,000-bushel capacity at Port Kelley, Wash. (mile 110.8 above Celilo) ; a 540,000-bushel elevator at Patterson, Wash. (mile 77.4 above Celilo) ; and directly across the Columbia River from Pat- terson, Wash., a 670,000-bushel elevator. At Umatilla, Oreg. (between mile 289.4 and 290.2 above the mouth), there are stor- age facilities for handling approximately 9,200,000 gallons of petroleum products and 156,000 gallons of aqua ammonia, with truck, rail, and water connections. There is a railroad located on each bank of the river, but there is no physical connection be- tween the railroad and the river except as noted. At Irrigon, Oreg. (mile 77.6 above Celilo), there is a privately owned wharf for the shipment of lumber and general cargo by barge. Also, on the Oregon shore across the river from Patterson, Wash., there is a privately owned dock for the shipment of general cargo by barge. Located on the Snake River, main tributary of the Columbia River (between mouth and mile 2.7), there are privately owned storage facilities for handling the following: Approximately 46.818,000 gallons of petroleum products, with truck, rail, water and pipeline connections; 11,411,155 pounds of anhvdrous am- monia; 893,646 gallons of aqua ammonia: 25,112 gallons of sul- phuric acid; 32,606 barrels of asphalt emulsions with truck, rail and water connections; and storage facilities for 11,199 barrels of bulk cement. These facilities, with planned extensions, are considered ade- quate for existing commerce. Overations and results during fiscal year. Reconnaissance and condition surveys determining channel depths at Owyhee, Canoe RIVERS AND HARBORS-WALLA WALLA, WASH., DIST. 1783 Encampment, and Four O'clock Rapids were made. Also a re- connaissance survey with a fathometer was made for the entire reach from head of Celilo Canal to McNary lock and dam. The work was performed at a cost of $7,485. Condition at end of fiscal year. The authorized 7-foot channel 150 feet wide has been completed to McNary lock and dam. The controlling depth between Celilo Falls and McNary lock and dam is 7 feet, survey of August, 1954. For that portion of the project above McNary lock and dam the depths are in excess of 7 feet. The Arlington approach channel was completed in 1948. Total costs have been $2,191,133 of which $1,356,584 (including $400,000 emergency relief administration funds) were for new work and $834,549 for maintenance.

This provides for two jetties, the easterly, 951 feet long, and the westerly, not exceeding 676 feet long, at the mouth of the Snake River; a channel 8 feet deep at mean lower low water and 75 feet wide from Norton Sound through Snake River to the mouths of Bourbon and Dry Creeks, in the city of Nome, terminating in a basin of similar depth 250 feet wide and 600 feet long, revetting the banks of the rivers; and protecting all existing waterfront improvements on the easterly beach by means of a rockmound seawall 3,350 feet long extending easterly from the east jetty. The extreme tidal range is 2.8 feet and the range between mean.lower low water, and mean higher high water is 1.15 feet, but water levels are influenced more by wind than tide. Levels of 7 feet below mean lower low water have been observed during offshore winds, and a level of 14 feet above mean lower low water has been observed during a southerly storm. The actual cost for new work was $1,348,240. The latest (1952) approved estimate for annual cost of maintenance, ex- clusive of the seawall, which is to be maintained by local interests, is $47,500, excluding $2,500 to be contributed by the city of Nome. Extension of the jetties to authorized lengths is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this portion was revised in 1954 and was estimated to be $852,000 with $20,000 annual maintenance.

In accordance with the provisions of the River and Harbor Act of August 8, 1917, which authorized the initial improvement, the city of Nome furnished evidence, ac- cepted by the Secretary of War on December 22, 1917, that it would contribute $2,500 annually toward the maintenance of the improvements and furnish all lands or easements necessary to the proper execution of the work. These conditions have been met annually as required. The conditions required in River and Harbor Act of June 16, 1948, which authorized the seawall, have been fully complied with. Terminal facilities. Cargoes and passengers from ocean ves- sels are lightered to and from shore a distance of about 2 miles. Traffic enters the dredged channel and is handled over the revet- ment, where transfer, facilities that are open to public use have been installed by a lighterage company. These facilities are con- sidered adequate for existing commerce. Operations and results during fiscal year. There was no new work during the fiscal year. Maintenance was performed by Government plant and hired labor, 1 July through 27 October 1956 and 1 June through 30 June 1957, and consisted of dredging 14,200 cubic yards, at a cost of $36,064, $33,564 from Federal funds and $2,500 from contributed funds. Condition at end of fiscal year. Construction of the original 335- and 460-foot jetties and the revetments was commenced in 1919 and completed in 1923. Reconstruction of the jetties with concrete to modified lengths of 240 feet and 400 feet was com- pleted in 1940. Dredging of the channel and the original 200- by 250-foot basin was commenced in 1919 and completed in 1922. Construction of the seawall was commenced in 1949 and completed in June 1951. Dredging of the 400-foot extension of the basin was commenced in 1949 and is complete with the exception of small areas in the northerly portion of the small boat harbor extension and around the Corps of Engineers marine ways which are not required. Timber revetments have been refaced with sheet steel piling. A portion of the east jetty was repaired in 1954 with a concrete fill. A portion of the west jetty has eroded to a point where some patching is required at two locations.

Fully complied with for original project. In accordance with the provisions of the River and Harbor Act of March 2, 1945, local interests are to give assurances satisfactory to the Secretary of the Army that they will revise and extend the present mooring float system in the harbor in conformity with a plan that will ultimately provides accommodations for approxi- mately 330 small boats at one time in the dredged area. The town of Petersburg was advised of the requirements of local cooperation on October 10, 1947, and on December 26, 1947, indicated its willingness and ability to comply. The River and Harbor Act of 1954 requires that local interests provide without cost to the United States necessary lands, easements, and rights-of-way, in- cluding quarry rights and spoil-disposal areas, both for new work and subsequent maintenance; agree to provide and maintain, with- out cost to the United States, necessary mooring facilities and utilities, includipg a public landing with suitable supply facilities open to all on equal and reasonable terms; and agree to hold and save the United States free from claims for damage due to construction and maintenance of the project. Terminal facilities. There are six wharves and one float in Petersburg Harbor. One privately owned and operated wharf which serves as passenger, general cargo, and cold-storage termi- nal is open for public use. Another privately owned and operated wharf, serves as cannery, cold storage and moorage for govern- ment vessels. The publicly owned float is open for public use for mooring and servicing small craft. All of the other wharves are used for industrial purposes. These facilities are adequate, except that additional moorings are required for small boats. Operations and results during fiscal year. New work per- formed under contract consisted of removal of 91,170 cubic yards of material from an area of about 135,000 square feet adjacent to and shoreward of the original basin, and the outer one-third of the small boat basin at a cost of $139,295.

WRANGELL HARBOR, ALASKA Location. Wrangell Harbor is located on the west side of the northern end of Wrangell Island, 824 miles from Seattle and 160 miles from Juneau. (See U. S. Coast and Geodetic Survey Charts Nos. 8164, 8161 and 8201.) Existing project. This provides for a rubblemound breakwater 300 feet long to protect the southern portion of the outer harbor, and dredging a mooring basin 600 feet long, 400 feet wide, and 10 feet deep below mean lower low water within the protected area; an inner basin in the tide flat area east of Shakes Island and construction of a breakwater 320 feet long on the reef north of Shakes Island. The range between mean lower low water and mean higher high water is 13.8 feet. The extreme tidal range is 26 feet. Heavy swells, dangerous to small fishing boats, are caused by the wind, which causes an additional rise of about 1 foot. Construction of the breakwater north of Shakes Island was placed on inactive status as material to be used from the inner basin was unsuitable and the breakwater considered unnecessary for safe moorage of vessels. The cost of this portion was last revised in 1956 and was estimated to be $6,500.

Gold Creek rises in the coastal mountains approxi- mately 4 miles east of Juneau and flows through the western section of the City of Juneau and empties into Gastineau Channel. Its total length is about 5 miles and it drains an area of about 10.2 square miles. (See U. S. Coast and Geodetic Survey Chart No. 8235.) Existing project. The plan of improvement provides for a rein- forced concrete channel lining 1,717 feet in length for that portion of Gold Creek passing through the city of Juneau together with 1816 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the necessary intake and downstream energy dissipating struc- tures. The project will provide protection to the city of Juneau from a project flood of 4,800 cubic feet per second. The estimate of cost for new work, made in 1957 is $464,000. The project was authorized by the Flood Control Act approved September 3, 1954 (H. Doc. 54, 82d Cong., 1st sess.). This document contains the latest map of the locality. Local cooperation. The Flood Control Act of September 3, 1954, provides that local interests give assurances satisfactory to the Secretary of the Army that they will (a) provide without cost to the United States all lands, easements, and rights-of-way neces- sary for the construction of the project; (b) contribute to the United States the cost of making all necessary alterations to bridges and utilities and of constructing a guard fence on both banks of the channel; (c) hold and save the United States free from damages due to the construction works; and (d) maintain all the works after completion in accordance with regulations prescribed by the Secretary of the Army. The city of Juneau was notified of the requirements of local cooperation in letter dated February 18, 1949, and assurances of cooperation were con- tained in Resolution from the Common Council of Juneau and transmitted in letter dated February 24, 1949. In 1934 and 1935 the Works Projects Administration con- structed a cemented rubble channel at a cost of approximately $84,000. In addition, the city of Juneau has expended about $51,910 for emergency channel repairs since 1946. Operations and results during fiscal year. New work per- formed under contract consisted of partial construction of diver- sion channel and prepartion of the channel for concrete lining by excavation of 1,211 cubic yards of material and placement of 451 cubic yards of backfill and the placement of about 140 linear feet of concrete channel lining at a cost of $73,826.

ANNUAL REPORT OF THE BOARD OF ENGINEERS FOR RIVERS AND HARBORS-FISCAL YEAR 1957 The Board of Engineers for Rivers and Harbors was authorized by section 3 of the River and Harbor Act approved June 13, 1902. The enabling act provided for the organization in the Office of the Chief of Engineers by detail from time to time from the Corps of Engineers of a Board of five engineer officers (later increased by legislation to seven members), a majority of whom shall be of a rank not less than lieutenant colonel. The act with subsequent amendments directs that all reports on authorized preliminary examinations and surveys of river and harbor and flood-control projects be reviewed by the Board prior to submission of the reports by the Chief of Engineers with his recommendation to Congress. The review is for the purpose of determining the economic and engineering justification of the projects reported upon. The Board is also required upon request by the appropriate committees of Congress to review and report through the Chief of Engineers upon any authorized project or desired improvement previously reported upon with a view to recommending the initiation of a project or modification of an existing project. The Chief of Engineers may refer to the Board for conisideration and recommendation all special reports ordered by Congress and may prescribe such other duties as he desires. In 1920, additional duties were assigned to the Board under the terms of section 8 of the Merchant Marine Act of 1920, and of various River and Harbor Acts, notably that of February 1891; the terms of the latter Act were expanded by section 11 of the River and Harbor Act approved 22 September 1922. In com- pliance with the Merchant Marine Act, the Board is responsible, in cooperation with the Maritime Administration, for collecting, compiling, and publishing information on more than 100 sea and Great Lakes ports. Under the River and Harbor Acts, the Board compiles and publishes data on the water transportation lines of the United States, and publishes National summary statistics on the waterborne commerce of the United States. It provides technical supervision over the collection, compilation, and pub- lication of the data on the waterborn commerce of the United States. In addition to the duties prescribed by law, the Board performs such other duties as may be assigned by the Chief of Engineers. During the fiscal year ending June 30, 1957, the Board performed the following assigned duties: Reviewed and submitted recom- mendations on certain Corps of Engineers policies and procedures as directed; reviewed and commented on reports of other Federal agencies pertaining to water resource development; conducted investigations and studies of the economics of ports and water- ways; provided guidance to the field offices of the Corps of Engineers in the field of waterways economics; prepared Engineer Intelligence Reports and special planning studies on Foreign Ports; and prepared vulnerability reports on certain ports of the United States. 1819 1820 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY,, 1957 On June 30, 1957, the Board was composed of the following members: Major General Charles G. 'Holle, Special Assistant to the Chief of Engineers, (chairman) ; Major General Gerald E. Galloway, Division Engineer, Missouri River Division; Brigadier General Paul D. Berrigan, Division Engineer, North Central Division; Brigadier General Lyle B.

The Board considered 121 reports, actin favorably on 6 ard unfavor- ably o_25 orts of survey; reommen a survey be ma e and reporting un- vorably on 28 preliminary examination reports; and also reviewed the special report on the Brazos River and Tributaries, Texas; issued one "not convinced" notice on a favorable report; returned one report to the field for reconsidera- tion; and deferred action on seven reports. The Board mended construction on projects totaling $316,424,500, of which -recom- $237,497,900 was the estimated cost to the United States and $78,926,600 the cost to local interests, which included work to be done by local interests and cash :contributions. The esti- mated cost of construction for the 22 projects for which surveys were recommended totaled $97,887,300, Of the 53 unfavorable survey and preliminarynexanrinrtin rerts acted on by the Board 33 r"ep~ds involved construction work estimated to cost BOARD OF ENGINEERS FOR RIVERS AND HARBORS 1821 $512,828,420. No estimates were made on the balance of 20 survey and preliminary examination reports as they covered investigations that were obviously unfavorable or no longer neces- sary. The estimated cost of the Brazos River Project was $155,594,000. The total estimated cost of construction on the 92 reports on which cost estimates were included was $1,082,734,220.. In addition to its review of preliminary examinations and sur- veys, the Board submitted reports or comments on reports to the Chief of Engineers as follows: Nine reports of other Federal agencies on water resource development; Twenty two special civil works reports to the Chief of Engineers; Seventeen engineer intelligence studies covering 19 foreign ports; Three reports on vulnerability of United States ports, covering six ports; and Fifty two Special planning studies on foreign ports.

Headquarters of the Commis- sion are in the Mississippi River Commission Building, Vicksburg, Miss. The Mississippi River Commission is charged, under the direc- tion of the Secretary of the Army and supervision of the Chief of Engineers, with prosecution of improvements for flood control of the Mississippi River and of its tributaries and outlets in its alluvial valley, so far as they are affected by Mississippi River backwater, between Head of Passes, La. (mile 0), and Cape Girardeau, Mo. (mile 1,016), and with prosecution of improve- ments in the interests of navigation between Cairo, Ill. (mile 964), and Baton Rouge, La. (mile 232). It also is charged with prosecu- tion of certain flood-control works on the Mississippi River and on tributaries so far as they are affected by backwater, between Cape Girardeau and Rock Island, Ill. (mile 1,446), and with prosecution of improvements on designated tributaries and outlets below Cape Girardeau for flood control, major drainage, and related water uses such as navigation and water supply for agricultural use. Authorized operations of the Commission below Cape Girardeau are conducted by the district engineers of the United States Army Engineer Districts, New Orleans, Vicksburg, and Memphis, within the areas described below, in accordance with approved directives and programs and congressional appropriations therefor.

Kansas City District: (Missouri River Division) -Missouri River (sec. 6) levees to St. Charles, Mo. (backwater limits). MISSISSIPPI RIVER AND ALLUVIAL VALLEY BELOW CAPE GIRARDEAU, MO. Location and description: The Mississippi River rises in Lake Itasca, Minn., and flows in a general southerly direction for 2,350 miles through the central portion of the United States to empty into the Gulf of Mexico about 115 miles below New Orleans. It is improved for barge navigation for about 1,837 miles to Minneapo- lis, Minn. The major tributaries are the Missouri, Ohio, St. Francis, White, Arkansas, Yazoo, and Red Rivers which drain 1,245,000 square miles in all or part of 31 States between the Rocky and Appalachian Mountains and parts of two Canadian provinces. Below Cape Girardeau, Mo., 53 miles above the Ohio River, the river bottom lands widen abruptly into the alluvial valley of about 35,460 square miles which was originally subject to flood overflow. For descriptive purposes, this area has been subdivided into the St. Francis, White, Tensas, Atchafalaya, and Lafourche Basins west of the river, and the Yazoo and Pontchar- train Basins east of the river. A major part of the alluvial valley has been protected from floods by levees which confine flood flows within a flood plain having an average width of about 5 miles. Observations made by the Mississippi River Commission to June 30 show approximate maximum and minimum discharges be- tween the levees as follows: Cairo to White River, 2,000,000 and 70,000 cubic feet per second; thence to Red River, 2,150,000 and 90,000 cubic feet per second; thence to the Gulf of Mexico, 1,500,000 and 80,000 cubic feet per second in the Mississippi River and about 650,000 and 12,000 cubic feet per second in the Atchafalaya River. As the 1927 flood flow was not confined between the levees, maximum discharges recorded do not include the entire flow of the 1927 flood, the maximum of record below White River. Low water stages, generally, obtain from August to December. High water and flood stages usually occur in the late winter or early spring, but great floods such as that of 1937 have occurred as early as January in the upper reaches of the lower river. Extreme ranges in stages recorded at representative gages are about 60 feet at Cairo; 55 feet at Memphis; 57 feet at Red River Landing; and 23 feet at Carrollton. The river is non- tidal above the mouth of Red River, where amplitude of the tide rarely exceeds 0.1 foot during extreme low water. 1826 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 PREVIOUS PROJECTS The project outlined in a report by the Commission dated Febru- ary 17, 1880, contemplated improvement of the channel to secure a least depth of 10 feet at extreme low water by contraction of the low water channel, protection of banks against caving, and con- trol of floodwater by levees. For further details, see page 1944, Annual Report for 1932, and page 1682, Annual Report for 1937. Flood-control-general projects previously authorized, which have been incorporated as features of the project, are listed below.

EXISTING PROJECT The existing project for the Mississippi River and tributaries in the alluvial valley between the Head of Passes, La. and Cape Girardeau, Mo. provides for the protection thereof from floods by means of levees, floodwalls, floodways, reservoirs (in the Yazoo and St. Francis Basins), bank stabilization, and channel improve- ments in and along the river and its tributaries and outlets insofar as affected by backwater of the Mississippi River, including levee work on the main stem between Cape Girardeau and Rock Island. The project also provides for channel realinement and improve- ment including bank stabilization and dikes to reduce flood heights; control the natural tendency of the river to lengthen by meandering; protect the levees from being destroyed by caving banks; and provide a 12- x 300-foot navigation channel between Baton Rouge, La. and Cairo, Ill. The locations of major Mis- sissippi River project improvements for flood control and naviga- tion, including main stem levees and appurtenant drainage struc- tures and spillways, channel realinement and dredging, bank revetment, and dikes are listed in table A. The locations of levee work accomplished under the provisions of section 6 of the Flood Control Act approved May 15, 1928, are shown on table E-4. The project provides for harbor improvements on the main stem at Baton Rouge (Devils Swamp), La., Vicksburg, Miss., and Memphis, Tenn. The locations of these improvements are shown on table A. The locations of project improvements on tributaries and outlets in designated basins in the alluvial valley below Cape Girardeau are listed in table B. Table C contains data pertinent to dams and reservoirs. MISSISSIPPI RIVER COMMISSION 1827 TABLE A.

MISSISSIPPI RIVER COMMISSION 1835 Local cooperation. Section 2 of the Flood Control Act ap- proved May 15, 1928, stated that, in view of the great expenditure, estimated at approximately $292,000,000, heretofore made by the local interests in the alluvial valley of the Mississippi for protec- tion against the floods of that river; in view of the extent of National concern in the control of these floods in the interest of National prosperity, the flow of interstate commerce, and the movement of the United States mails; and in view of the gigantic scale of the project involving flood waters of a volume and flowing from a drainage area largely outside the States most affected and far exceeding those of any other river in the United States; no local contribution to the construction cost of the project is re- quired. Requirements of local cooperation stipulated in section 3 of the act of May 15, 1928 cover (a) the maintenance of completed flood control works; (b) acceptance of ownership of lands acquired by the United States and turned over to local interests under the provisions of section 4 of the act; (c) provision without cost to the United States of all rights-of-way for main stem levees and (d) holding the United States free from damages by floods. Subse- quent amendments to the 1928 act have provided for varied modi- fications and additions to these requirements to meet the special local conditions applicable to off-main stem features of the project. Such requirements have in general been complied with by local interests as construction of the project has advanced. Terminal facilities. See volume 1 of the 4-volume report of the Board of Engineers for Rivers and Harbors, entitled, "Survey of Terminals and Landings on the Inland Waterways of the United States" 1942, and Port Series for New Orleans, La., No. 20, 1947, and Lake Charles, La., No. 21, 1947, also folio of Flood Control and Navigation Maps of the Mississippi River, Cairo, Ill., to the Gulf of Mexico (24th edition), 1956. OPERATIONS AND RESULTS DURING FISCAL YEAR Commission activities. The 249th session of the Commission was held on board the U. S. steamer Mississippi en route on the Mississippi River from Cairo, Ill. to Baton Rouge, La., October 1-5, 1956. The 250th session was held in the office of the Presi- dent of the Commission at Vicksburg, Miss., on March 19, 1957. This session was held for the purpose of considering the compre- hensive review report of the Mississippi River and tributaries project and reports on the Natchez, Miss. and Greenville, Miss. harbor projects. The 251st session was held on board the U. S. steamer Mississippi en route on the Mississippi River from Cairo, Ill., to mouth of Old River, and on the Atchafalaya River to Morgan City, La., May 6-13, 1957. The 252d session Wvas held in the office of the President on June 24, 1957, this session being for the purpose of final review and approval of the interim report on main stem features of the comprehensive review of the Mississippi River and tributaries project. On the river trips, major features of the project were inspected and public hearings were held, at which representatives of local government agencies, navigation, levee, commercial, and other interests presented problems per- taining to flood control and navigation. During the 249th session, 1836 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 the Commission observed construction under way at the Old River control site. During the 251st session a similar inspection was made of the progress of work at the site. On May 12, 1957 an inspection trip by automobile was made of the Atchafalaya Basin levee system from Krotz Springs to Morgan City. The members of the Commission then traveled by automobile to New Orleans where a public hearing was held on May 13, 1957 in the auditorium of International House. In addition to these inspection trips, members of the Commission inspected major flood control and navigation improvements under the jurisdiction of the Commission and reviewed and acted on the following reports: a. "Review Report on the Mississippi River and Tributaries Project with Respect to Harbor Improvements at Natchez, Miss.," dated April 15, 1957, and inclosed report of the Vicksburg District Engineer dated March 19, 1957. b. "Review of Mississippi River and Tributaries Project with respect to Harbor Improvements at Greenville, Miss.," dated April 26, 1957, and inclosed report of the Vicksburg District Engineer dated April 12, 1957. c. "Interim Review Report on Main Stem Features, Mississippi River and Tributaries Project," dated June 24, 1957 which was prepared with the assistance of the District Engineers of the United States Army Engineer Districts, Memphis, Vicksburg, and New Orleans. Comprehensive review of project. Work has continued on the project review in response to a resolution by the Committee on Public Works of the United States Senate, adopted June 12, 1954, which authorized a review of the project for flood control of the Mississippi River in its alluvial valley and for its improvement from the Head of Passes to Cape Girardeau, Mo., as one compre- hensive whole and in its entirety, and submission of recommenda- tions for any modifications that are advisable with respect to the project or any feature of the project. The interim reports on main stem features and harbors at Natchez and Greenville, Miss. have covered the need for navigation improvements on the main stem, the adequacy of the main stem works, and the cost of completing the main stem features of the project. The comprehensive review of the project, to be submitted by June 30, 1958, will cover the adequacy and cost of completing the off-main stem flood control and major drainage features of the project, including modifica- tions and extensions that have been requested by local interests and the coordination of these features with the plans of other Federal and State agencies for the conservation of water resources and development of water uses in the alluvial valley of the Mississippi River. In response to the request of the President, Mississippi River Commission, the interested State Conservation- ists of the United States Soil Conservation Service, with the assistance of the Forest Service and the Agricultural Research Service of the United States Department of Agriculture, are con- tinuing their cooperative investigations and studies and are fur- nishing information and economic data on agricultural and timber development in the alluvial valley for use in estimating the costs MISSISSIPPI RIVER COMMISSION 1837 and benefits of proposed flood control and drainage improvements. The Fish and Wildlife Service of the United States Department of the Interior, with the assistance of interested State Game and Fish Commissions, is continuing investigations and studies and is developing plans for the coordination of the proposed improve- ments with the conservation of fish and wildlife habitat. Work has continued on the supplementary study to determine the bene- fits from upstream reservoirs in the relief of flood damage to lands and the increase of low streamflow on the lower Mississippi River below the Missouri River. This study is being carried on with the assistance of the United States Army Engineer Divisions, Missouri River, North Central, Ohio River, and Southwestern. The report thereon will be completed by December 30, 1958. During the current fiscal year, the New Orleans, Vicksburg, and Memphis District Engineers continued investigations and studies for the review of navigation improvement, levees and bank stabilization on the main stem, and for the review of levees along supplementary floodways and along the lower Arkansas and Red Rivers. The Vicksburg District Engineer also made investiga- tions and studies to determine the need for and economic feasibility of harbor improvements at Natchez and Greenville, Miss. and submitted reports thereon. Other work carried on by the District Engineers for the project review included flood control and drainage investigations and studies in the following off-main stem areas: New Orleans. Eastern Rapides and South Central Avoyelles Parish area and Atchafalaya Basin. Vicksburg. Yazoo, Tensas, and lower Arkafisas Basins. Memphis. Lower White, St. Francis, West Tennessee tribu- taries, and West Kentucky tributaries Basins. Flood damage investigations for the reservoir benefit study were made by the District Engineers for unprotected lands along the main stem and in backwater areas. The St. Louis District Engineer made similar flood damage investigations for lands along the Mississippi River between the Ohio and Missouri Rivers. The results of these investigations are being reviewed by the United States Soil Conservation Service. The President, Mississippi River Commission, and his engi- neering assistants made periodic inspections of flood control, navigation, and related works under the existing project along the Mississippi River and tributaries in the alluvial valley from Cape Girardeau, Mo., to the Gulf of Mexico. No major floods occurred on the main stem during the fiscal year, but through the combined efforts of local authorities and Federal personnel close contact with local flood situations was maintained and operations were carried out efficiently. Surveys, gages, and observations. Routine hydrographic sur- veys of the river between Head of Passes and Cairo, construction surveys, and special surveys and inspections were made as re- quired. Gages were maintained and discharge observations made. Results thereof are presented in detail in annual pamphlets issued by the Mississippi River Commission. 1838 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Alluvial valley mapping. Preparation and publication of con- toured maps of the alluvial valley and quadrangle maps (scale 1: 62,500) were continued. On the new 16-sheet, scale 1: 250,000 map of the alluvial valley of the lower Mississippi River, the compilation of seven sheets preparatory to review and printing has been completed, and four sheets are in various stages of compilation. The 1956 (24th) edition of the folio of flood control and navigation maps, scale 1: 62,500, covering the Mississippi River from Cairo, Ill. to the Gulf of Mexico was printed. The 1957 (25th) edition of this map folio is under preparation. Some 4,331 flight miles of aerial photographs were taken covering por- tions of the Mississippi River, some tributary rivers and special areas in the New Orleans, Vicksburg, and Memphis Districts. Mosaics of various scales covering the Mississippi River Delta below Head of Passes, Atchafalaya Basin, and portions of the Boeuf River, Big Bayou, and other areas were completed. Work accomplished in the districts follows: New Orleans District. Four revised editions-Chef Menteur, Rigolets, Oyster Bayou, and Bayou Sale quadrangle maps were published.

The present construction status of the project features listed in tables A and B follows: Mississippi River levees: There are 1,713 miles of Mississippi River levees below Cape Girardeau (including those on the north bank of the lower Ohio River and the south banks of the lower Arkansas and Red Rivers). There are 1,466 miles of these levees built to project grade and section with earthwork aggregating about 1,084,000,000 cubic yards as listed in tables E-1 through E-3. Graveled or hard- surfaced roads have been constructed on 227 miles of these levees. Below Baton Rouge, in the New Orleans District, about 134.4 miles of levee are protected against river wavewash by either timber structures or levee-slope pavement. Shore-erosion-protec- tion works have been constructed along 16.0 miles of levee. In order to insure the adequacy of the main stem levees, including those on the south banks of the Arkansas and Red Rivers, addi- tional levee construction at an estimated cost, after July 1, 1957, of $42,377,000 is recommended to provide a standard 3-foot free- board, adequate levee cross section, construction of berms for levee stabilization and seepage control, levee wavewash protection where necessary, drainage structures, and roadways for proper inspection and maintenance. Bonnet Carrespillway, La.: The spillway structure was completed in February 1931, and the remaining work was completed in December 1936. Operations and maintenance of the spillway are carried on as required. (See pp. 2089-2091, Annual Report for 1938 for description.) Birds Point-New Madrid floodway, Mo.: It is impracticable and possibly dangerous to provide works in the main stem that will eliminate the need for the Birds Point-New Madrid floodway. However, the flood protection provided at Cairo permits some modification of the planned use of the flood- way. Enlargement of the front line and fuseplug levees to provide less frequent use of the floodway is recommended at an estimated cost of $840,000. Work on the authorized project for a closure structure to prevent backwater flooding of the lower end of the floodway has not been started. Flood-control work under section 6, May 15, 1928 Act: The status of levee work that has been constructed under the provisions of section 6 of the 1928 Act, is summarized in table E-4. MississippiRiver-channel improvement: In carrying out the authorized channel improvement program between Baton Rouge and Cairo, 16 cutoffs have been excavated to decrease the channel length between these cities by about 170 miles. The effect of this channel shortening, in increasing its flood-carrying capacity, is stated on page 1811, Annual Report of Chief of Engineers for 1943. In the last 5 years much progress has been made in advancing the overall channel stabilization program, involving the construction of bank revetment, dikes, MISSISSIPPI RIVER COMMISSION 1853 and improvement dredging, to prevent the river from regaining its former length due to its natural tendency to meander. There are now in place 373 miles of operative bank revetment on the Mississippi and Ohio Rivers as listed in tables D-1 through D-3. A navigation channel 9 feet by 300 feet is maintained by dredging as required during the low-water season. Since 1928 annual main- tenance dredging has averaged about 30 million cubic yards. Due to the growing effectiveness of the channel improvement program average dredging requirements are steadily being reduced, and an increase in navigable depth is being obtained. A long-range plan has been developed and recommended to bring about the desired program of channel improvement between Cairo and the Head of Passes including additional bank revetment, dredging, training works, and foreshore protection at an estimated cost, after July 1, 1957, of $398,000,000. Baton Rouge Harbor (Devils Swamp) : Design memorandum for this feature and plans and specifica- tions for the first 21/ miles of the proposed 5-mile channel were completed during the fiscal year. Vicksburg Harbor: Construction of the project started in December 1956. A small amount of clearing has been done. Preparation of plans and specifications for channel dredging and industrial fill is in progress. Memphis Harbor (Tennessee Chute) Completed features include the closure dam, batture embank- ment, pile dikes, approach fill and roadway, Nonconnah Creek sewer extension, industrial embankment and wavewash protection. Work on the Ensley portion of the project, which will consist of about eleven miles of levee and a pumping station, has not been started. Atchafalaya Basin, La.: a. Wax Lake Outlet and Charenton Canal. Wax Lake Outlet and Charenton Canal are complete. Alterations to the New Iberia & Northern Railway bridge were completed July 18, 1955. b. Atchafalaya River and Basin. Levees extend along both banks of the Atchafalaya River. Approximately 49.2 miles of the 50.8 miles in the east bank system and 60.0 miles of the 61.3 miles in the west bank system have been built to approved grade and section. c. Atchafalaya Basin floodway. Levees have been built to ap- proved grade and section on the west side of the Atchafalaya Basin from Mansura Hills to Hamburg to confine flood waters within the West Atchafalaya floodway, the Atchafalaya River, and along Bayou des Glaises from Hamburg to Simmesport. Continuous levee systems extend along the east and west limits of the floodway. The east protection levee extends from Morganza to Cutoff Bayou; 67.4 miles of the 107.9 miles in this levee system having been built to grade and section. The west protection levees extend from Hamburg to Wax Lake Outlet and thence via the lower floodway protection levee to Berwick drainage canal,: with 95,1 miles of the 1854 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 128.2 miles in the system built to grade and section. The lower Atchafalaya system of levees is partially complete west of Berwick and the lower Atchafalaya River from Berwick drainage canal to Wax Lake Outlet and thence to the Charenton drainage canal, including Bayou Sale and Teche Ridge levees. Of the 60.9 miles in this system, 59.0 miles have been built, and 57.5 miles are to grade and section. For status of these levees, see table E-1. Ring levees have been completed at Simmesport, Melville, and Krotz Springs. Landside borrow-pit channels have been excavated along the west protection levee between the Bayou des Glaises diversion canal at Hamburg and the Charenton drainage canal, and along the east protection levee between Fordoche and Ramah for the passage of intercepted drainage. Floodway and basin improvements, other than levees, completed prior to 1943 are as described on pages 1884 and 1885 of the Annual Report of the Chief of Engineers for 1943. Improvements completed since then include a drainage structure in the Simmesport ring levee; floodwalls at Morgan City, Berwick, and Tiger Island, 1,891, 5,219, and 1,990 feet in length, respec- tively; two pumping plants at Morgan City (Morgan City and Tiger Island) ; locks at Berwick, Bayou Boeuf, and Bayou Sorrel; a drainage structure and outlet channel at Bayou Courtableau; a floodgate and access bridge at Charenton drainage canal; flood- gates at Calumet on the east and west sides of Wax Lake Outlet; a channel 9 feet by 100 feet from Bayou Boeuf to Bayou Long, which acts as a drainage outlet for the floodway and forms a part of the alternate route for the Gulf Intracoastal Waterway; im- provement of interior drainage west of Berwick by excavation of a channel from Calumet to Wax Lake East levee borrow pit and construction of Ellerslie, Bayou Yokely, and Maryland pumping stations, and Wax Lake West and Wax Lake East drainage structures. Between Courtableau and Krotz Springs, over the West Atcha- falaya floodway, the New Orleans, Texas & Mexico Railway Co.'s high-level crossing is complete, except for deferred construction. Improvements, other than levees, now in progress are as fol- lows: Improvement dredging between miles 57.9 and 63.7, Whiskey Bay pilot channel extension, of which 3.3 miles between miles 57.9 and 61.2 have been completed; construction of Franklin pumping station, which is 19 percent complete; and test-pile work for the high-level crossing of United States Highway No. 190, under a reimbursable contract with the Department of Highways, State of Louisiana, which is 3 percent complete. The Atchafalaya Basin floodway is approximately 81 percent complete. In order to insure the adequacy of the flood-carrying capacity of the Atchafalaya Basin floodways, the dredging of resistant areas to enlarge the lower Atchafalaya River channel, the enlarge- ment of the basin protection levees drainage structures, and the construction of roadways on levees where necessary for inspection and maintenance are recommended at an estimated cost, after July 1, 1957, of $65,825,000. MISSISSIPPI RIVER COMMISSION 1855 d. Morganza floodway (includes Morganza structure). At the upper end of the floodway, the combined high-level crossing for State Highway No. 30, the Texas & Pacific Railway's Port Allen branch line, and the Morganza control structure is complete except permanent paving of the highway approaches, and other deferred construction as provided for under the reimbursable contracts. The forebay levee has been degraded. About midway, the Texas & Pacific Railway Co.'s main line crosses the floodway between McKneely and Red Cross; this high-level crossing was completed February 9, 1956, when the deferred construction period expired. At the lower end, United States Highway No. 190 was completed September 12, 1953, and the New Orleans, Texas & Mexico Railroad high-level crossing was completed August 12, 1944. All scheduled construction has been completed.

To furnish the technical advice and assistance required in this program, the Chief of Engineers was directed to form a board of seven members to assist in the conduct of studies, review the reports on such investigations, and submit recommendations. By executive ruling the agency applying for a cooperative study under this act is required to contribute 50 percent of the estimated cost of the investigation. Each study results in a report containing plans and specific recommendations as to methods or means to improve or remedy a condition at a particular locality. A summary of such cooperative studies follows : Number of applications for studies appoved prior to July 1, 1956------ 95 Number of applications for studies approved during fiscal year 19571.... 7 Number of reports completed prior to July 1, 1956____---------- 102 Number of reports completed during fiscal year 1957------------------ 8 Number of studies remaining to be completed2 - - - - - - - - - - - - - - - - - - - - - - 16 1 Does not include application approved for extending study area for one report in Massachusetts. 2 These studies involve 18 localities and will result in 18 reports. Section 5 of the River and Harbor Act approved August 30, 1935 (Public Law 409, 74th Cong.) provided that every report submitted to Congress looking to the improvement of the entrance at the mouth of any river or at any inlet for navigation contain information concerning the configuration of the shore line and the probable effect of the proposed improvement on the coast line for a distance of not less than 10 miles on either side of the entrance. The basic law authorizing beach erosion studies was supplemented by the act approved July 31, 1945 (Public Law 166, 79th Cong.), which made it the duty of the Chief of Engineers, through the Beach Erosion Board, in addition to participating in cooperative investigations under the basic law, to make general investigations with a view to preventing erosion of the shores of the United States by waves and currents and determining the most suitable methods for the protection, restoration, and development of beaches; and to publish from time to time such useful data and information concerning the erosion and protection of beaches and shore lines as the Board may deem to be of value to the people of the United States. Federal participation in the cost of protecting the shores of the United States was established in the act approved August 13, 1946 (Public Law 727, 79th Cong.), subsequently amended by Public Law 826, 84th Congress approved July 28, 1956. The latter act declared it to be the policy of the United States to assist in the construction, but not the maintenance, of works for the restoration and protection against erosion, by waves and currents, of the shores of the United States, its Territories and possessions; 1887 1888 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 provided that the Federal contribution to any project shall not exceed one-third of the cost and that the plan of protection shall have been specifically adopted and authorized by Congress after investigation and study by the Beach Erosion Board. Periodic beach nourishment by deposit of sand fill at suitable intervals of time may be considered as contruction eligible for Federal aid for a specified period, if in the opinion of the Chief of Engineers it is the most suitable and economical protective measure. Shores other than public :are eligible for Federal assistance toward their protection if public benefits result therefrom, the amount of Federal assistance being adjusted in accordance with the degree of such benefits. The word "shores" as used in the act includes all the shore lines of the Atlantic and Pacific Oceans, the Gulf of Mexico, the Great Lakes, and lakes, estuaries, and bays directly connected therewith. At the end of fiscal year 1957 the Board comprised the following members: Maj. Gen. Charles G. Holle, United States Army, presi- dent; Brig. Gen. Henry J. Hoeffer, United States Army, division engineer, South Atlantic Division; Brig. Gen. William F. Cassidy, United States Army, division engineer, South Pacific Division; Col. Clarence Renshaw, United States Army, division engineer, North Atlantic Division; Mr. Thorndike Saville of New York, Dean of the College of Engineering, New York University; Mr. Morrough P. O'Brien of California, Dean of the College of En- gineering, University of California; Dr. Lorenz G. Straub, en- gineering consultant, Division of Waterways, Department of Conservation, State of Minnesota. In addition to the foregoing, Brig. Gen. Theron D. Weaver, United States Army, served as president of the Board for a part of the year. The following approved cooperative studies were either in progress or awaiting funds on June 30, 1957.

During fiscal year 1957, the Board carried out studies and in- vestigations in cooperation with appropriate agencies of various States and territories and with the field offices of the Corps of Engineers to develop effective works for the protection and BEACH EROSION BOARD 1889 stabilization of the shores and beaches of coastal and lake waters. The Board completed the review of cooperative beach erosion con- trol reports on Chatham, Mass.; Saugatuck River to Byram River and Thames River to Niantic Bay, Conn.; Sandy Hook to Barnegat Inlet, N. J. (Review) ; the State of Delaware; Humboldt Bay (Buhne Point) and Santa Cruz County, Calif.; and Berrien County, Mich. The Board reviewed 17 reports on navigation improvements which included information as to probable effects on adjacent shore lines, as provided in section 5 of the River and Harbor Act approved August 30, 1935, and also reviewed nine hurricane appraisal reports and two hurricane survey reports. The Board has continued general investigations of means of protecting shores and beaches against erosion, in accordance with authorization contained in the act approved July 31, 1945 (Public Law 166, 79th Cong.). Publication of the Board's Bulletin was continued on an annual basis to disseminate pertinent information to the public. Five technical papers prepared by the staff were presented before meetings of technical societies of which three were or are being published in the technical press; one additional paper has been prepared for presentation later in the year. Revi- sions and addenda required to keep up-to-date with current re- search the comprehensive report entitled "Shore Protection Plan- ning and Design", which has been published as Technical Report No. 4 of the Board, were prepared for publication during the year. Fifteen technical memorandums were published by the Board. Two additional technical memorandums are now in press as are two Bulletin papers prepared by members of the Beach Erosion Board staff; seven additional papers reporting results of research by the staff were in preparation. In addition eight reports were prepared for, and issued to, other agencies on projects carried out for them; nine contracts with universities for research to supplement the staff activities were continued. Three projects were prosecuted by the Waterways Experiment Station of the Corps of Engineers at Vicksburg for the Board. During the year six members of the staff took part in a seminar given by Princeton University on shore processes and coastal structures. At the end of the year, studies by the staff were in progress on: the characteristics of ocean waves by actual measurement at five localities; the improvement of wave forecasting procedures for both inland and ocean waters; methods of bypassing sand at inlets; sources of beach material; an analysis of Mission Bay field data; wave run-up and overtopping on shore structures; wave run-up on permeable beaches; effects of tidal inlets on adjacent beaches; re- forming of waves after breaking; effect of groin fields on rate of littoral transport; field study of Moriches Inlet, Long Island; re- examination of data on artificially nourished and constructed beaches; wave forces on piles; amount of sand suspended in the surf zone; equilibrium profile of beaches under prototype waves; model scale effects; effect of water temperature on sand transport; and adaptation of the wave spectrum analyzer to laboratory and full field use. In addition the staff has worked on 13 research projects of significant size for various other government agencies, and one project for a private company. CALIFORNIA DEBRIS COMMISSION This Commission, consisting of 3 officers of the Corps of Engi- neers appointed by the President with the consent of the Senate, created by the act of Congress approved March 1, 1893 (27 Stat. L., p. 507), was organized in San Francisco, Calif., on June 8, 1893, and has jurisdiction and duties extending over the drainage area of the Sacramento and San Joaquin Rivers, comprising the great central valley of California and extending from the crest of the Sierra Nevada on the east to that of the Coast Range on the west, and from Mount Shasta and the Pitt River Basin on the north to the Tehachapi Mountains on the south. These rivers empty into the head of Suisun Bay, ultimately discharging into the Pacific Ocean through the connecting bays and straits and the Golden Gate. The Commission also has charge of improvements for the control of floods on the Sacramento River. The duties prescribed by the act creating the Commission are: First: To regulate hydraulic mining in such a way as to permit its resumption and continuance under such restrictions as to pre- vent the resulting debris from being carried into navigable waters or otherwise causing damage. Second: To study and report upon general hydraulic and hydraulic-mining conditions and matters affecting or affected by them and to make surveys, mature, and adopt plans for the purpose of improving the navigability, deepen- ing the channels, and protecting the banks of the rivers, and afford- ing relief from flood damages. While the Commission was to "adopt" plans as a result of its study, the act creating it did not provide means for directly carry- ing them out. Congress, however, has from time to time adopted certain of the plans formulated by the Commission and charged it with their execution, under the direction of the Secretary of the Army and the supervision of the Chief of Engineers.

Operations are largely limited to the territory be- tween Mount Lassen on the north and the Yosemite Valley on the south, on the western watershed of the Sierra Nevada. (See U. S. Geological Survey sheets for the area, 25 in number.) Existing project. This improvement provides for regulating hydraulic mining operations, planning the improvement of condi- tions upon the Sacramento and San Joaquin Rivers and their tribu- taries affected by such operations, and the preparation of plans to enable hydraulic mining to be resumed in their drainage areas. 1891 1892 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 In addition, the Secretary of the Army is authorized to enter into contracts to supply storage for water and use of outlet facilities from debris storage reservoirs for domestic and irrigation pur- poses and power development, upon such conditions of delivery, use, and payment as he may approve. Applications of prospective miners are fully investigated by the California Debris Commission and permits to operate are issued to those who provide satisfactory debris-restraining basins by con- struction of suitable dams where necessary or agree to make pay- ment for storage in Government-constructed, debris-restraining reservoirs constructed under the act of June 19, 1934, as set forth below. For location and description of Government-constructed debris-restraining reservoirs for general hydraulic mining see Im- provement No. 3, "Sacramento River and tributaries (debris control), Calif." The average annual Federal cost of this work during the past 5 years was $6,081. The existing project was authorized by the following: Acts Work authorized Documents Mar.

RIVERS AND HARBORS-CALIFORNIA DEBRIS COM. 1893 Local cooperation. Mine owners are required to bear all ex- penses incurred in complying with the orders of the Commission for regulation of mining and restraint of debris. Operations and results during fiscal year. Inspections of hydraulic mines were accomplished to determine the rate of debris movement into the debris-restraining basins and/or reservoirs and compliance of the mine owners with the requirements of the licenses issued. Cost of these inspections, regulation of hydraulic mining, issuance of licenses, and other administrative work was $5,000 during the fiscal year for maintenance. Administrative work overlaps that of improvements 2, 3, and 4, hereunder and that of the Sacramento Engineer District. Condition at end of fiscal year. The Commission has received 1,289 applications for hydraulic mining licenses; 21 mines are licensed, of which five use storage behind Government debris dams. Surveys have been made of those portions of Yuba, Feather, Bear, and American Rivers containing large deposits of mining debris; of active mines, except those on the north fork of Yuba River above Bullards Bar Reservoir; and of Bullards Bar and Combie Reservoirs, to determine the rate of debris movement into the several reservoirs. Work remaining to be done is, in general, the continuation of the above or similar operations. The total cost of all work to June 30, 1957, was $763,977, for maintenance.

TREATMENT OF THE YUBA RIVER DEBRIS SITUATION- RESTRAINING BARRIERS, CALIF. Location. The works are on the Yuba River between Marysville and where the river emerges from the foothills, near Hammonton, some 10 miles easterly from Marysville, or about 9 miles below the Narrows. (See U. S. Geological Survey topographic map of the Sacramento Valley, Calif.) Existing project. This provides for storage of mining debris within the bed of the Yuba River by means of construction- of Daguerre Point Dam, a debris barrier, and by the restraint of flow channel to narrow limits by means of training walls and other regulation works. The object of storing this debris in the Yuba River-a nonnavigable stream-is to keep it from passing into the Sacramento and Feather Rivers to the detriment of navigation therein. The variation in water levels due to floods is about 12 feet. The total cost of new work, completed in 1935, was $723,259, of which $361,482 was from United States funds and $361,777 from funds contributed by the State of California. (For details 1894 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 of this project in its original form, see Annual Report, 1917, p. 1810, "Previous projects.") The average annual maintenance cost during the past 5 years was $78,816, consisting of an average of $39,427 from United States funds and $39,389 from funds contributed by local interests. The expenditure of $100,000 from United States Deferred Main- tenance funds, together with $100,000 from contributed funds, a total of $200,000, in addition to regular and contributed main- tenance funds in fiscal year 1957 is reflected in the above average. Exclusion of this $200,000 expenditure would reflect in the above average. Exclusion of this $200,000 expenditure would reflect an average annual maintenance cost during the past 5 years of $38,816, consisting of $19,427 from United States funds and $19,389 from funds contributed by local interests. The existing project was adopted in a rather indefinite form by the River and Harbor Act of June 3, 1896, and in its more definite form by the River and Harbor Act of June 13, 1902 (H. Doc. 431, 56th Cong., 1st sess.). (For the latest published map, see U. S. Geological Survey topographic map of the Sacramento Valley, Calif.) Local cooperation. Fully complied with for new work. Total costs for new work for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $361,777 from funds contributed by the State of California. In addition, training walls were built on each bank below Daguerre Point for a distance of 11,250 feet and just above Daguerre Point, on the south bank, for a distance of 11,000 linear feet by two gold-dredging companies in connection with their dredging operations. It was estimated (1920) that it would have cost the United States $450,000 to build these training walls. Flood channels were also built by gold-dredging companies within the confines of the project works. It was estimated (1926) that the cost of equally effective works to restrain debris movement would have been more than $776,000 to the United States. The State of California contributes annually an amount equal to the Federal allotment for maintenance. Operations and results during fiscal year. Regular Funds. Maintenance: Operations during the year included condition and operation studies, including maintenance of gages and gage read- ings; preparation of plans and specifications; and removal of debris and clean-out of fish ladder, all of which were accomplished by hired labor.

Maintenance: Restoration and bank protection was accomplished by contract along the right and left banks of Yuba River from Simpson Lane Bridge to Dantoni Orchard, Yuba County. Condition at end of fiscal year. Construction of the project was initiated in November 1902, and completed in 1935. Three train- ing walls, having a total length of 85,100 feet and providing two 500-foot-wide channels, were built, partly by gold-dredging com- panies and partly by the United States. A cut was made through Daguerre Point and a concrete spillway constructed therein. The channel between Marysville and the training walls were cleared of obstructions. Dikes were built to block off old sand channels. The project has been maintained in a satisfactory condition suit- able to the purpose intended and the result has been to hold in the Yuba River millions of cubic yards of mining debris which would otherwise have passed into the channels of Feather and Sacra- mento Rivers to the detriment of navigation. The December 1955 floods caused extensive damage to the banks. Approximately 15,000 linear feet (approximately $450,000, of which $200,000 has been accomplished (fiscal year 1957) with deferred maintenance funds, with a balance of $250,000 remaining to be done) of bank protection is required to restore stability of banks where retards and bank protection works were destroyed, and in new locations where the river threatens to create a new channel. In addition, the decking of Daguerre Dam was damaged and repairs will be necessary. Regulation of the river necessitates annual clearing in the chan- nel to provide adequate capacity for flood flows, and the construc- tion of bank revetment or current deflection works to prevent ero- sion. The State of California annually contributes an amount equal to the Federal funds for maintenance work. The Yuba Consolidated Gold Fields was issued a Department of the Army permit in 1944 for dredging a 600-foot channel which would replace the two 500-foot channels above Daguerre Point Dam. The new channel will give almost a 90 ° approach for flows toward the crest of the dam. Work under the permit was completed in October 1956. The total cost of the project to June 30, 1957, was as follows: Funds New work Maintenance Total United States funds: Regular appropriations--------------.-- $361,482 $460, 518 $822, 000 Deferred maintenance-.......----------------....----------................---------- 100, 000 100, 000 Total United States funds............ 361,482 560, 518 922, 000 Contributed project funds------------------ 361,777 560,223 922, 000 Total all funds--......................-------------------- 723, 259 1,120, 741 1,844, 000 1896 REPORT OF THE CHIEF OF ENGINEERS, U.

SACRAMENTO RIVER AND TRIBUTARLES, CALIF. (DEBRIS CONTROL) Location. The project reservoirs are to be constructed in the watersheds of the Yuba, Bear, and American Rivers, Calif. (See U. S. Geological Survey sheets for the basin areas, seven in number.) Existing project. The project was designed to permit the re- sumption of hydraulic mining on a substantial scale and provides for construction of reservoirs for the purpose of retaining mining debris. Harry L. Englebright (Upper Narrows) Dam on Yuba River was completed in 1941 and North Fork Dam on the north fork of American River was completed in 1939. The total Federal cost of this new work was $4,646,872. The average annual maintenance cost during the past 5 years was $35,935. The completed reservoirs have recreational areas of approxi- mately 5 acres each. Studies have been made of the adequacy and improvement of these areas. It is estimated (1957) that such improvements to recreational areas will cost $7,500 and $15,000 for Harry L. Englebright Dam and North Fork Dam, respectively. The reservoir project sites on the Middle Fork of the American River and on Bear River are considered to be inactive and are excluded from the foregoing cost estimate. The estimated cost of this portion of the project is $2,298,128 (1935). The existing project was adopted by the River and Harbor Act of August 30, 1935 (Rivers and Harbors Committee Doc. 50, 74th Cong., 1st sess.). For latest published map, see the project document. RIVERS AND HARBORS-CALIFORNIA DEBRIS COM. 1897 The act approved November 6, 1945, provided that the dam con- structed at the Upper Narrows site on the Yuba River, in the State of California, should thereafter be known and designated as the Harry L. Englebright Dam. Local cooperation. Satisfactory assurances were furnished the Secretary of the Army for repayment of the capital cost of the reservoir from taxes on material hydraulically mined, under licenses, and impounded in these reservoirs. These funds are paid to the Director of Internal Revenue then credited by the Treasurer of the United States to the Debris Fund. Operationsand results duringfiscal year. Maintenance: Opera- tions during the year included maintenance and operation of the Harry L. Englebright and North Fork Dams and appurtenant service facilities; preparation of plans and specifications for reha- bilitation of generator facilities at North Fork Dam; and condition and operation inspections and studies, all of which were accom- plished by hired labor. In addition, hired labor was also utilized for studies of the adequacy and the cost of improvement of the existing recreational areas at the two dams. There were approxi- nately 19,000 and 24,000 visitor-days at Harry L. Englebright Dam and North Fork dam, respectively, during the year. Total cost for maintenance during the fiscal year was $25,706, fiom hydraulic mining in California funds. Condition at end of fiscal year. Construction of the North Fork Dam and Reservoir was initiated in 1937 and completed and in use at the end of the fiscal year 1939. The reservoir is located on the north fork of the American River about 5 miles northeast of the city of Auburn and 40 miles northeast of Sacramento. The dam is 155 feet high, 620 feet long, and the reservoir has a debris- storage capacity of 26,000,000 cubic yards. Construction of the Harry L. Englebright Dam was initiated in 1937 and completed in January 1941; the reservoir has been in use for storage of hydraulic mining debris. The reservoir is on the Yuba River about 20 miles northeast of the city of Marysville. The dam is 260 feet high, 1,142 feet long, and the reservoir has a debris stor- age capacity of 118,000,000 cubic yards. The two debris control structures are in good condition. The parking area has been enlarged at North Fork Dam to relieve the congested parking situation in the public use area. One recreation area at the North Fork Dam and Reservoir, approximately 5 acres, is maintained and operated by the Auburn Recreation Park and Parkway District under a license agreement approved in September 1953. The licensee has maintained and made some improvements to the existing facilities. Present public use of the area is about 24,000 visitor-days per year. The recreation area at Harry L. Englebright Dam and Reser- voir, approximately 5 acres, is maintained by the Corps of Engi- neers. Present public use of this area is about 19,000 visitor-days per year. Public use of these reservoir areas has more than doubled during the past 5 years and greatly overtaxes the present capacities. It is expected that if additional facilities are provided, future public 1898 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 use will increase accordingly. Studies have been made of the addi- tional facilities required; funds have not been made available for such construction to date. The primary purpose of the project was to make possible the resumption of hydraulic mining in the tribuatry watershed for which local interests are required to reimburse the United States according to the volume of debris contributed. However, hydrau- lic mining activity has practically ceased during recent years. Annual maintenance activities are required to protect the Federal investment and, in addition, maintenance of the project benefits the downstream navigation projects, primarily the Sacramento River Project, in that it prevents debris deposits in these channels and thus reduces the annual maintenance costs for the Sacramento River navigation channel. Maintenance of this project also helps to maintain flood-channel capacities in the downstream river reaches. In the case of Harry L. Englebright Dam and Reservoir an additional benefit is realized through the use of the head created for the generation of hydro- electric power. An existing contract with the Pacific Gas & Electric Co. calls for payment to the Federal Government of $18,000 per year for the first 30 years and $48,000 per year after that in return for the use of head at Engelbright Dam and genera- tion of hydroelectric power. Total payment through December 31, 1952, amounts to about $180,000; these funds are paid to the California Debris Commission and deposited for credit by the Director of Internal Revenue to the "Debris Fund". The total cost of the project to June 30, 1957, was as follows: Funds New work 1 Maintenance Total 1 United States: Regular funds--.....----------------- - $4,646,872 $284, 992 $4, 931,864 Hydraulic Mining in California funds.. -------------- 202,044 202, 044 Total.------------------------------ 4, 646, 872 487, 036 5,133, 908 I Exclusive of $644,503 costs from regular funds on inactive portion of the project.

FLOOD CONTROL-CALIFORNIA DEBRIS COMMISSION 1899 4. SACRAMENTO RIVER, CALIF., FLOOD CONTROL Location The works covered by this improvement are on the Sacramento River and tributaries in north central California from Collinsville to Ord Bend, a distance of 184 miles. Previous project. Improvement of the original project for Sacramento River was previously performed under the title of "Alleviation of Debris Conditions in the Sacramento and Feather Rivers, California." Debris resulting from hydraulic mining operations and natural erosion had obstructed the channels of these rivers by raising the riverbeds and reducing the capacity to such an extent that the streams broke through their banks and overflowed large areas during high floods, increasing the shoaling in the channels themselves. The large deposits of debris in the river channels and its variable movement downstream had im- paired their navigability. The construction and operation of hydraulic dredges was authorized with the object of removing deposits from the Sacramento River to improve navigation, with no definite limits in depth, width, or location of the work being prescribed. Work was accomplished from the mouth of the Sacramento River, in Suisun Bay at Collinsville, to Rio Vista, 14 miles above, and consisted of channel enlargement and levee con- struction. Local interests were required to contribute an equal amount toward the cost of the work and, in addition, to provide all rights-of-way for levees and spoil banks free of cost to the United States. These requirements were fully complied with. In addi- tion, the State of California constructed a retaining embankment for spoil deposit. This minor project was absorbed in the exist- ing project. The original project was adopted by the River and Harbor Act of June 25, 1910 (in accordance with report of California Debris Commission dated June 30, 1907, and printed in Annual Report for 1907, page 2262). For further details, see Annual Report for 1917, page 1815, and Annual Report for 1938, page 1995. Existing project. The Sacramento River Flood-Control proj- ect is a comprehensive plan of flood control for the Sacramento River and the lower reaches of its principal tributaries. The im- provement extends along the Sacramento River from Ord Bend in Glenn County, Calif., downstream to its mouth at Collinsville at the upper end of Suisun Bay, a distance of 184 miles, and com- prises a system of levees, overflow weirs, drainage pumping plants, and flood bypass channels or floodways designed to carry the sur- plus floodwaters without inundation of valley lands. The project provides for the enlargement of the Sacramento River below the mouth of Cache Slough to carry the entire flood discharge of the river basin; for making two cutoffs between the mouth of the Feather River and Colusa; for the construction of four bypass weirs, and reconstruction of Tisdale Weir; for construction of drainage outfall gates at Butte Slough and at Knights Landing; for the construction of levees along certain reaches of the main river and tributaries; for construction of three drainage pumping plants on the east side of Sutter Bypass; for construction of bank-pro- tection works and levee setbacks on the main river and tributaries 1900 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 from Ord Bend to Collinsville; for maintenance, during the con- struction period, of the enlarged river channel below Cache Slough, including revetment of the banks of the enlarged channel, and for operation and maintenance of gaging stations during the same period on navigable rivers and streams. The project also in- cludes channel clearing, rectification, snagging, and bank protec- tion along the Sacramento River and tributaries in Tehama County from Red Bluff southerly. Approximately 980 miles of levee construction are involved in the project. When completed, the project will provide adequate flood protection to about 800,000 acres of highly productive agri- cultural lands and to the cities of Colusa, Marysville, Yuba City, Sacramento, North Sacramento, and numerous smaller com- munities; two transcontinental railways; two transcontinental highways; and State and county highways and feeder railroads. It has made possible the reclamation of swamps and other over- flow land which have been developed to a high degree of use. The project is approximately 73 percent complete at the end of fiscal year 1957. The above levee improvements were supplemented by works au- thorized by the Flood Control Act of December 22, 1944, and May 17, 1950 (H. Doc. 649, 78th Cong., 2d sess., and H. Doc. 367, 81st Cong., 1st sess.). The levee construction and reconstruction pro- vided for in these authorizations, including levee protection of Upper Butte Basin and multipurpose reservoirs, are reported upon by the Sacramento District under improvement No. 7, "Sacra- mento River and tributaries, from Collinsville to Shasta Dam, Calif." The latest approved estimate (July 1957) of Federal cost for the existing project (exclusive of the improvements authorized by the Flood Control Acts of Dec. 22, 1944, and May 17, 1950), including new work and maintenance, is $77,600,000, for construction. The record flood of December 1955 disclosed certain structural and functional deficiencies which could not be identified until the system was tested by this major flood. Such deficiencies will be corrected under the present project authorization. Operation and maintenance of the project- after completion will be the responsibility of local interests; as units of the project are completed they are transferred to agencies of the State of California for operation and maintenance. The existing project was adopted by the Flood Control Act of March 1, 1917 (H. Doc. 81, 62d Cong., 1st sess., as modified by Rivers and Harbors Committee Doc. 5, 63d Cong., 1st sess.), and modified by the Flood Control Act of May 15, 1928 (S. Doc. 23, 69th Cong., 1st sess.), the River and Harbor Act of August 26, 1937 (Senate committee print, 75th Cong., 1st sess.), and the Flood Control Act of August 18, 1941 (H. Doc. 205, 77th Cong., 1st sess.). Recommended modifications of project. In House Document 272, 84th Congress, 2d session, it was recommended that the exist- ing project for flood control on the Sacramento River be extended to Keswick Dam for the purpose of zoning the area below the dam, FLOOD CONTROL-CALIFORNIA DEBRIS COMMISSION 1901 and that the project be modified by the construction of bank protection and incidental channel improvements along the Sacra- mento River from Chico Landing to Red Bluff. Local interests would be required to furnish all lands, easements, and rights-of- way necessary for construction of the project; hold and save the United States free from damages due to the construction works; and maintain the works after completion in accordance with regu- lations prescribed by the Secretary of the Army. The estimated (1953) Federal cost is $1,360,000 for construction, subject to the condition that only such work be constructed as is found economic- ally justified at the time of construction in the light of conditions then prevailing along the river. Local cooperation. Flood Control Act of May 15, 1928, pro- vided that local interests were to contribute one-half the cost of construction of project levees, estimated at $3,191,500, and furnish the lands, rights-of-way, and easements therfor. The modified project which was adopted in the River and Harbor Act of August 26, 1937, provided that the State of California should execute and maintain the remainder of the general flood control project, now being done or to be done by the United'States, and make illegal any levee, ditches, or other works in the bypasses or on the lands reserved for overflow that might reduce or impede the flood runoff, unless approved by the California Debris Com- mission; should hold and save the United States free from damages due to construction works: And provided further, That the bank revetment for protection of levees above Cache Slough, and the levee reconstruction recommended in the project document (Senate committee print 75th Cong., 1st sess.), should not be undertaken until the State of California, political subdivisions thereof, or responsible local agencies have agreed to provide without cost to the United States all lands, easements, the rights-of-way for said works, including the cost of all alterations to highways, road crossings, and drainage and irrigation facilities incident to the work, and shall have contributed one-third of the cost of bank revetment and levee reconstruction, with the understanding that the contribution of funds will be made as required by the prog- ress of the work; and the State of California was to undertake the operation of the movable top of Sacramento Weir in accord- ance with the schedules established by the California Debris Commission. The modification of the project authorized in the Flood Control Act of August 18, 1941, relieves local interests of all future con- struction costs under the existing project, but requires them to give assurances satisfactory to the Secretary of the Army that they will (1) provide all needed lands, easements, and rights-of- way free of cost to the United States, (2) bear the expense of necessary highway, railroad, and bridge alterations, (3) hold and save the United States free from claims for damages resulting from construction of the works, and (4) maintain and operate all flood control works after completion, in accordance with regulations prescribed by the Secretary of the Army. 1902 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Chapter 196 of the Statutes of 1953, State of California, offi- cially adopted the project and modifications thereto. Local in- terests are represented by the Reclamation Board of the State of California. The Board has met all requirements to date and has furnished assurances of required local cooperation to meet all requirements for work as needed. Local interests have contributed for project work a total of $4,949,438 for levee construction, bank protection works, and levee setbacks, of which $4,939,752 was for new work and $9,686 for maintenance. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including the above required non-Federal contributions, amount to $107,000,000 (July 1957). The cost to local interests for local cooperation required in the correction of deficiencies disclosed by the record flood of December 1955 is not yet available. Total estimated cost of new work to June 30, 1957, for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to over $85,000,000. Units or portions of the project are transferred to agencies of the State of California for operation and maintenance as they are completed. Annual cost of such maintenance is estimated at $1,000,000 (1957). Operationsand results during Fiscal Year. New Work. Con- tinuing contracts, initiated in Fiscal Year 1956, were completed at follows: Grand Island-stone protection along east levee Steamboat Slough; Sutter Island-stone protection along Sutter and Steamboat Sloughs; stone protection along Elkhorn, Sutter, and Miner Sloughs; construction of back levee, Reclamation Dis- trict No. 108, Sycamore Slough to Southern Pacific Railroad bridge; levee enlargement of Hastings Tract, Hastings Cut up- stream; and normal bank protection at four locations along Sacramento River between miles 102.0 and 123.1. Levee crown surfacing, Sherman and Twitchell Islands; con- struction of an inlet structure, Sacramento River-Elkhorn Slough near Clarksburg; and Ryer Island-stone protection along left bank Cache Slough from Ferry to Miner Slough, initiated by contracts during fiscal year 1956, were completed. Clearing activities, initiated at the following locations during fiscal year 1956, were also completed: Bear River from Feather River upstream approximately 4 miles, by contract; Feather River, Sutter Bypass upstream to Yuba River, by continuing contract; and Sutter Bypass, Fremont Weir upstream to Nelson Bend, by continuing contract. Patrol road construction, Sacramento River, west levee, Colusa to Knights Landing, was accomplished by contract. Stone pro- tection of Ryer Island, along Steamboat, Sutter, Miner, and Cache Sloughs, was initiated by contract. In addition, the following work was accomplished by hired labor and rented equipment: Continuation of repairs to levee FLOOD CONTROL-CALIFORNIA DEBRIS COMMISSION 1903 slopes, Twitchell and Sharman Islands, and initiation of stage construction of levees along Hastings Tract. Miscellaneous work, including surveys, explorations, and prep- aration of contract plans and specifications, was accomplished by hired labor during the fiscal year. Hired labor was also utilized in the preparation of operation and maintenance manuals and as-built drawings for completed portions 'of the project. Purchase and installation of net communication facilities was accomplished by hired labor. A total of 841,401 cubic yards of embankment was placed in levees along the project waterways during the fiscal year. There was no maintenance work accomplished during the year. Total Federal cost of all new work during the fiscal year was $3,257,782. Miscellaneous construction (nonproject) accomplished for the State of California at its expense in connection with acquisition of rights-of-way for levees cost $290,276, for new work. Total cost of all work during the fiscal year was $3,548,058, of which $3,257,782 was from United States funds (regular ap- propriations) and $290,276 from contributed (nonproject) funds. Condition at end of fiscal year. Construction of the existing project, initiated in fiscal year 1918, is approximately 73 percent complete. The channel improvement accomplished to date has produced a channel with a capacity of 579,000 cubic feet per second in the Sacramento River below Cache Slough. In addition, dis- charges up to 21,000 cubic feet per second can be diverted from the Sacramento River through Georgiana Slough. Completed major project items include approximately 773 miles of levees; 5 weirs with a combined discharge capacity of 602,000 cubic feet per second; two cutoff channels; two sets of outfall gates; channel im- provement and clearing in the Sacramento River, Butte Creek, Putah Creek, and Sutter and Tisdale Bypasses; construction of two main bypasses or floodways and secondary bypasses at Tisdale and Sacramento Weirs and at Wadsworth Canal; construction of Knights Landing Ridge Cut and of Cache Creek settling basin; a considerable amount of river levee bank protection, installation of gaging stations; and enlargement of Sacramento River below Cache Slough. A total of 90,655,475 cubic yards embankment has been placed in levees along the project waterways. The cutoffs at Collins Eddy and between Wild Irishman and Kinneys Bends were made in 1918 and 1919, respectively. Sacramento Weir was completed in 1917, Fremont Weir in 1924, Tisdale and Moulton Weirs in 1932, and Colusa weir in 1933. Outfall gates at Knights Landing were constructed in 1930 and at the mouth of Butte Slough in 1936. Pumning nlants on Sutter Bypass were completed in 1944. Work items with reference to the clearing, snagging, rectification of channels, and bank protection on Sacramento River and tributaries in Tehama County and from Red Bluff southerly, provided for by Flood Control Act of August 18, 1941, were accomplished in fiscal ypars 1947, 1948, 1949, and 1951. The total cost of this work was 1904 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 $126,355 of which $30,144 was by contract and $96,212 by hired labor. The floods of December 1955 were the most. widespread and destructive of any in the recorded history of Northern California since the legendary floods of 1862 and 1867. As a result of heavy, prolonged rains, outstanding flood peaks occurred on practically all streams within the project area. In the Sacramento River Basin, including the lower delta area, about 260,000 acres of land were flooded, principally by the Feather, Bear, and Sacramento Rivers. The flood-control operation of Shasta Reservoir on the upper Sacramento River, and Folsom Reservoir on American River controlled flood flows to the capacity of downstream flood- control channels. Although the Sacramento River was confined within its levees, overflow occurred at all of the relief weirs along the river (which are a part of the Sacramento River Flood-Con- trol project), and flooding occurred within the project floodways and natural storage basins, including Sutter, Tisdale, Sacramento, and Yolo Bypasses and Butte Basin. During the period from December 23 to 31, 1955, flood condi- tions in the lower Sacramento River were aggravated by unusually high tides which opposed the passing of floodwaters through the Sacramento-San Joaquin Delta. Levees of the Sacramento River Flood Control project confine Feather River from a few miles downstream from Oroville to its mouth. The levees provide a limited degree of protection to Marysville, Yuba City, Gridley, and adjoining areas. During the December flood, they protected Marysville and the area upstream on both sides of the river. Below Marysville and Yuba City, the levee system could not carry the unusual flood flow of the Yuba River combined with a large flow from the Feather River. Project de- sign floods for Feather River below Yuba River were exceeded, and breaks occurred on both sides of the river. The areas flooded by Feather River totaled about 100,000 acres. Floodwaters con- tinued to flow into the areas from two major breaks for 2 to 4 weeks. With the exception of failures of the project levees of the Feather River levee below Yuba City and at Nicolaus, the Sacra- mento River Flood Control project functioned effectively to reduce flood flows and flood damages along Sacramento River. Flood damages prevented by the project during the December 1955 flood were estimated at $90,000,000, and flood damages prevented during the January-February 1956 floods were estimated at $15,000,000, a total of $105,000,000. Immediately following the flood of December 1955, a thorough investigation of the project works disclosed certain structural and functional deficiencies which could not be identified until the system was tested by this major flood. Such deficiencies will be corrected under the present project authorization. Work remaining to be accomplished includes completion of levees (along Sacramento, Feather, and Yuba Rivers, and the adjoining bypasses and tributaries), bank protection, and clear- ing overflow channels and bypasses; clearing, snagging, and recti- FLOOD CONTROL--CALIFORNIA DEBRIS COMMISSION 1905 fication of channels on Sacramento River and tributaries in Te- hama County and from Red Bluff southerly; and dredging of the enlarged flood channel below Cache Slough, with continued mainte- nance dredging until that part of the project below Cache Slough is completed.

ARMY ENGINEER WATERWAYS EXPERIMENT STATION ORGANIZATION AND FUNCTIONS The Chief of Engineers, by letter dated June 18, 1929 to the President of the Mississippi River Commission, directed the establishment of a hydraulic laboratory in the alluvial valley of the Mississippi. This institution is the Waterways Experi- ment Station with installations at Vicksburg, Miss. and Jackson, Miss. It was initially established in 1929, under the jurisdiction of the President, Mississippi River Commission. By General Order No. 9, Office, Chief of Engineers, July 29, 1949, the Station was transferred to the direct jurisdiction of the Chief of Engineers, effective August 10, 1949. Col. A. P. Rollins, Jr., Corps of Engineers, is director. The organization comprises the Hydraulics, Soils, Concrete, Technical Services and Construction Services Divisions, and the necessary administrative and service facilities for the conduct of experimental research and development and field exploration work. The Flexible Pavement Branch of the Soils Division conducts airfield, landing mat, and trafficability studies for the Office, Chief of Engineers. The Concrete and Soils Laboratories also serve as Division Laboratories for the Lower Mississippi Valley Division. The Mississippi River Commission Field Printing Plant is located at and operated by the Station. The experiment station has as its functions the experimental investigation of problems in hydraulics, soil mechanics, concrete, and flexible pavements presented to the Station for study, as well as research and development work in those fields; technical super- vision of hydraulic model testing at other Corps of Engineers hydraulic laboratories, including the Bonneville Hydraulic Lab- oratory, St. Anthony Falls Hydraulic Laboratory (St. Paul District), and the hydraulic laboratory of the Los Angeles Dis- trict; prototype testing in fields of hydraulics, soils and concrete; and technical supervision over hydraulic testing performed under contract with universities or other outside agencies for the Corps of Engineers. Work is performed on a reimbursable basis pri- marily for other Corps of Engineers offices, and also, with au- thority of the Chief of Engineers, for other Government agencies, private concerns, and foreign Governments. The experiment station maintains close contact with the field in all experimental work, both by station personnel visiting the field and by engineers from the field visiting the station while model studies or other testing are in progress. The waterways experiment station is also charged with the as- sembling of experimental engineering data from all sources, domestic and foreign, in the technical fields assigned to it; the translation and interpretation of these data; and the dissemina- tion thereof to other Corps of Engineers offices through its re- search center and technical reference library. During fiscal year 1957, one annual summary, 100 reports of individual studies 1907 1908 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 conducted at the waterways experiment station and nine trans- lations of foreign articles were distributed to Corps of Engineers offices and interested outside agencies. In addition, the editing and printing units of the Technical Services Division completed 155 miscellaneous assignments for the WES and other offices, making direct distribution for 32 of these assignments. OPERATIONS AND RESULTS DURING FISCAL YEAR All work accomplished at the waterways experiment station is initially financed by the revolving fund (except general investi- gations and military contracts), reimbursement therefor being obtained directly from agencies for whom the work is performed. The cost for operation of the station for the 12 months ending June 30, 1957 amounted to $5,468,818, of which $5,072,573 was charged to establishments served for practical research investiga- tions and related services, and $396,245 for permanent improve- ments. Of the reimbursable work, $2,907,629 was charged to civil funds, $2,089,549 to military funds, and $75,395 to non- governmental agencies. The total cost incurred for operation of the Waterways Experiment Station to June 30, 1957, amounted to $62,460,635, of which $52,330,716 was for reimbursable opera- tions and $10,129,919 for the cost of permanent improvements and miscellaneous operating expenses. PERMANENT INTERNATIONAL ASSOCIATION OF THE CONGRESSES OF NAVIGATION By an act approved June 28, 1902, Congress appropriated the sum of $3,000 per year for the support and maintenance of the Permanent International Commission of the Congresses of Navi- gation and for the payment of the actual expenses of the properly accredited national delegates of the United States to the meetings of the congresses and of the Commission. An increase in this ap- propriation to $5,000 per year was authorized by the River and Harbor Act approved June 30, 1948. Beginning with the fiscal year 1936, such expenses were paid by allotment from the general appropriation for the improvement and maintenance of river and harbor works. In fiscal year 1954 the allotment of funds for these purposes was included under General Expenses, Office, Chief of Engineers, a single year appropriation. The object of the as- sociation is the promotion of inland and maritime navigation by means of organized congresses, and the publication of pertinent information. Its headquarters are in Brussels, Belgium, but the congresses are held in various countries upon invitation. The association is supported principally by member nations, but the privileges of membership are also extended to corpora- tions, libraries, and individuals. Governments are represented by delegates, the number of delegates being based on the amounts received annually from such governments and their nationals for the expenses of the Commission. Corporate membership may or may not include the privilege of representation by delegates. Two classes of corporate membership are available. The class paying the higher annual subscription has the privilege of representation by delegates. Life individual membership may be secured upon the payment of a single fee or ordinary individual membership upon the payment annually of a fixed fee. The general affairs of the association are managed by a Permanent Commission with the assistance of a Permanent Coun- cil. The Commission is composed of delegates from the supporting governments, and the Council is chosen from members of the Permanent Commission, the representation in each case being according to the amount of the annual contribution. Due to the large number of American members of the Interna- tional Association, an informal national organization known as the American Section was authorized by the Chief of Engineers. The American members of the International Commission com- prise the National Commission which acts as the governing body of the American Section. The Assistant Chief of Engineers for Civil Works, United States Army, and the Resident Member of the Board of Engineers for Rivers and Harbors, are ex-officio members of the International Commission, and Chairman and Secretary, respectively, of the National Commission. Two members of the National Commission are elected to be members of the Permanent Council of the International Association.

Representation of the American Section on the Permanent International Council was by General Weaver, Colonel Hall until the expiration of his term as a member of the Commission on December 31, 1956, and General Vogel who replaced Colonel Hall. No meetings of the Permanent International Commission were held during the fiscal year because the meeting normally held in June was postponed until July to coincide with the XIXth International Navigation Congress to be held in London, England, July 8-20. Semiannual bulletins Nos. 43 and 44, published in one volume, were distributed to all members of the American Section and to Federal agencies concerned with navigation matters. These bul- letins contained technical articles on waterways of international interest and an account of the proceedings of the. 1956 annual meeting of the Permanent International Commission. American authors were invited to submit papers on each of the eleven topics selected for discussion at the XIXth Congress. These papers were reviewed and submitted to the Executive Secre- tariat at Brussels, Belgium, for printing along with similar papers on these subjects, prepared by eminent authors from other mem- ber nations. The printed papers have been distributed to all PERMANENT INTERNATIONAL ASSOC. OF CONGRESSES 1911 members of the Association. The Secretary of the American Section issued six newsletters at irregular intervals during the year to all corporate and individual members, informing them of the activities of the International Association and of the American Section. The membership of the American Section on June 30, 1957, totaled 649, consisting of 577 individual and 72 corporate members. Federal funds, limited to $5,000, were expended or obligated as follows: Annual United States contribution to the association _ $1,500.00 Outstanding obligations covering traveling expenses of dele- gates to the London Congress (July 1957) estimated at__ $372.50 and administrative expenses estimated at---------------624.00 996.50 Total expenditures estimated at-___ _________o_ -___ $2,496.50 INVESTIGATIONS AND SUPERVISION OF PROJECTS UNDER THE FEDERAL WATER POWER ACT The Federal Water Power Act of June 10, 1920, created the Federal Power Commission, composed of the Secretary of War, Secretary of the Interior, and Secretary of Agriculture, with authority to grant permits and licenses for hydroelectric develop- ments in all waters over which Congress has jurisdiction. The act further required that the work of the Commission be performed by and through the Department of War, Interior, and Agriculture, and their engineering, technical, and other personnel, except as may be otherwise provided by law. By the act of June 23, 1930, entitled "An act to reorganize the Federal Power Commission," sections 1 and 2 of the Federal Water Power Act of June 10, 1920, were amended. A commis- sion was provided for to be composed of five commissioners to be appointed by the President, by and with the advice and consent of the Senate. The necessity of performing the work through the Departments of War, Interior, and Agriculture was also removed and the Commission authorized to appoint such officers and employees as are necessary in the execution of its functions. By title II of the Public Utility Act of 1935, approved August 26, 1935, the original Federal Water Power Act was made part I of the Federal Power Act, and parts II and III added to that act. The law also provides that no waterpower license affecting the navigable capacity of any navigable waters of the United States shall be issued until the plans of the dam or other structures affecting navigation have been approved by the Chief of Engineers and the Secretary of the Army. There is further provision where- by any person or corporation intending to construct project works in any stream over which Congress has jurisdiction, other than navigable waters, shall file a declaration of intention for the pur- pose of ascertaining whether or not the jurisdiction of the Federal Power Commission will attach. During the past fiscal year work of an engineering nature has been assigned and accomplished as follows: Plans approved by Chief of Engineers and Secretary of the Army in ac- cordance with sec. 4(e) of Federal Water Power Act -_ - 17 Reports submitted on application for preliminary permits or licenses or amendments thereto_ _ 55 Licenses and permits under supervision ------ --- _ 9 The necessary expenses of transportation and subsistence of personnel engaged in investigations and the cost of supervision under the provisions of the Federal Power Act are paid from ap- propriations made for the Federal Power Commission. All other costs of administration of the laws in question are paid from funds available for general expense of the Corps of Engineers. During the fiscal year funds were expended as follows for the investigation of waterpower projects in cooperation with the Federal Power Commission and the supervision of operations under waterpower permits and licenses: From appropriations for the Commission $246. 87 From appropriations for General expense of the Corps of Engineers------------------------------------------ 6, 500. 00 STotal _---- ---- -__-- _ ---- $6, 746.87 1913 MISCELLANEOUS CIVIL WORKS In addition to the work of improving rivers and harbors, civil works of a miscellaneous character as indicated below have been committed to the Corps of Engineers.

CROIX RIVER BOARD OF CONTROL Constitution and duties. The Board was organized pursuant to conditions in the orders of the International Joint Commission approving the maintenance and operation of the dam built by the St. Croix Water Power Co. and the Sprague Falls Manufac- turing Co., Ltd., across the St. Croix River at Grand Falls in the State of Maine, and subsequent agreements reached between the Governments of the United States and the Dominion of Canada. The Board is charged with the duty of formulating and ad- ministering rules under which the power plant and accessories are to be operated to prevent as nearly as possible a level of water at the dam higher than 203.5 (mean sea-level datum), and to secure the users of water below Grand Falls the flow of water to which they are entitled. The Board is also charged with the supervision of the operation of all fishways on that portion of the St. Croix River that forms the international boundary. On October 2, 1934, the International Joint Commission issued an order approving the reconstruction of the dam, owned by the Canadian Cottons, Ltd., extending across the St. Croix River from Milltown in the Province of New Brunswick, Canada, to Milltown in the State of Maine, United States of America, which contained the following conditions: 1. That the reconstructed dam be so operated as to ensure that the forebay levels rise to no higher elevation than that which has heretofore obtained in the operation of the dam now being replaced. 2. That during times of flood the sluiceways of the dam shall be sufficiently open to ensure passage of the river flow. MISCELLANEOUS CIVIL WORKS 1917 3. That the operation of the dam, insofar as is necessary to ensure the observance of the provisions of this Order, be under the supervision of the International St. Croix River Board of Control. Members of the Board. The members of the Board for the fiscal year 1957, were Mr. J. E. Peters, District Engineer, Water Re- sources Division, Department of Northern Affairs and National Resources, serving as Canadian member, and Brig. Gen. Robert J. Fleming, Jr., Corps of Engineers, serving as United States member, who was succeeded by Brig. Gen. Alden K. Sibley, Corps of Engineers, on April 8, 1957. Operationsduring the fiscal year. Supervision was maintained and inspections made by representatives of the Canadian and United States members to ensure that the regulations of the International Joint Commission were carried out. THE INTERNATIONAL LAKE CHAMPLAIN BOARD OF CONTROL Constitution and duties. The Board was organized pur- suant to the provisions of the orders, dated June 10, 1937 of the International Joint Commission, approving the construction and operation of certain remedial works in the Richelieu River at Fryer's Island in the Province of Quebec, Dominion of Canada. The Board is charged with the responsibility of ensuring com- pliance with the provisions of the order of approval insofar as they relate to the regulation of the levels of Lake Champlain. Members of the Board. The members of the Board for fiscal year 1957 were Mr. C. K. Hurst of the Department of Northern Affairs and National Resources, Water Resources Division, for Canada, and for the United States, Col. John T. O'Neill, Corps of Engineers, from July 1, 1956 to December 9, 1956 and Col. T. DeF. Rogers, Corps of Engineers, from December 10, 1956 to June 30, 1957. Operations and results during fiscal year. None. The con- struction of the Fryer's Island Control Dam was completed in December 1938. Gates have been installed but have not been operated, pending excavation of the natural river control upstream from the dam. INTERNATIONAL MASSENA BOARD OF CONTROL Constitution and duties. An order of the International Joint Commission issued after a hearing on the application of the St. Lawrence River Power Co. for permission to continue to maintain the submerged rock weir constructed by the company in the south Sault Channel of the St. Lawrence River, authorized the main- tenance of the weir and, among other things, provided for a board of engineers to pass upon and control the new and old works involved. Members of the Board. The Canadian member of the Board for the fiscal year was Mr. T. M. Patterson, director, Water Re- sources Branch, Department of Northern Affairs and National Resources, Ottawa. The United States member was Col. Loren W. Olmstead, Corps of Engineers. 1918 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Operationsduring the fiscal year. The Board kept in touch with conditions by means of inspections and with respect to the diver- sion by means of monthly reports of the power company, showing the amount of water diverted and powerhouse performance from day to day. A noticeable deterioration and increased discharge capacity have been noted in the central opening of the weir. How- ever, observation of the river levels at the entrance to lock 21 of the Cornwall Canal indicates that the drawdown effect of the en- larged weir opening has been more than compensated for by the backwater effect of construction work located in the vicinity of Long Sault Rapids downstream of the weir. The construction of the St. Lawrence River Power Project will obviate the need for the weir when the project is complete. Due to the present construc- tion activity on the St. Lawrence River project and the uncertainty as to the effect of various works in connection therewith upon the levels of the St. Lawrence River in the vicinity, it is considered that for the short remaining usefulness of the weir, no repairs to the structure are required. The weir was last inspected by the United States member on May 2, 1957. INTERNATIONAL ST. LAWRENCE RIVERBOARD OF CONTROL Constitutionand duties. The International St. Lawrence River Board of Control was appointed in February 1954 pursuant to the provisions of the Order of Approval, dated October 29, 1952, issued by the International Joint Commission for the construction of certain works for development of power in the International Rapids Section of the St. Lawrence River. The Board is charged with performing the duties assigned to it in the Commission's order of approval which includes the following items that are pertinent during the period of construction: a. The Board is to keep itself currently informed of the plans of the St. Lawrence River Joint Board of Engineers insofar as these plans relate to water levels and the regulation of the discharge of water from Lake Ontario and the flow of water through the International Rapids Section, and to consult with and advise the Joint Board of Engineers thereon. b. The Board is to determine the gages, measurements, and other services to be provided by the Hydroelectric Power Com- mission of Ontario and the Power Authority of the State of New York in order to furnish accurate records relating to water levels and the discharge of water through the International Rapids Section. c. In addition to the reports to be made to the Commission in accordance with the terms of the order of approval and the normal semiannual reports, the Board is to keep the Commission currently informed with regard to the discharge of water from Lake Ontario and the flow through the International Rapids section. At the meeting of the International Joint Commission in Toronto on January 25, 1957, studies of the regulation of Lake Ontario, in furtherance of such studies accomplished by the International Lake Ontario Board of Engineers, were assigned to the International St. Lawrence River Board of Control.

The Board of Control approved the fifth report by the Joint Working Committee on River Gaging, a joint committee of the Board of Control and the Joint Board of Engineers, and informed the Joint Board accordingly. Pursuant to the assignment to the Board of further studies on the regulation of Lake Ontario, the Board appointed a Working Committee which initiated such studies during the fiscal year. INTERNATIONAL LAKE ONTARIO BOARD OF ENGINEERS Constitution and duties. The International Lake Ontario Board of Engineers was appointed by the International Joint Commission in April 1953, under the Reference of June 25, 1952, relative to Lake Ontario levels. The Board is concerned primarily with the determination of measures which can be taken to regulate the levels of Lake Ontario for the benefit of shore-property owners, with due regard for the proposed plan for the St. Lawrence seaway and power development. The Board was requested by the Com- mission to advise the Commission, through interim reports, on problems which might be resolved prior to completion of the Board's studies. At its April 10, 1953 meeting, the Commission orally instructed the Board to give priority to the problems in that portion of Lake Ontario concerned with Gut Dam. Members of the Board. The members of the Board for fiscal year 1957 were Mr. T. M. Patterson, director, Water Resources Branch, Department of Northern Affairs and National Resources for Canada and Mr. G. A. Hathaway for the United States. Mr. Hathaway held the position of special assistant to the Chief of Engineers, Department of the Army, until his retirement from Government service on March 31, 1957. In view of the near com- pletion of the work of the Board, he has retained membership thereon beyond the date of his retirement. Activities during the fiscal year. The Board, assisted by its working committee, has continued the studies assigned to it by the International Joint Commission, outlined below: (a) A study of the various factors which affect the fluctuation of the water levels of Lake Ontario including the construction in the St. Lawrence River known as Gut Dam and the diversions of water into or out of the Great Lakes Basin; and (b) a study of plans for the regulation of Lake Ontario to determine if a more beneficial range of the water levels of Lake Ontario can be obtained for the benefit of shore-property owners so as to reduce the ex- tremes of stage which have been experienced, having regard to the MISCELLANEOUS CIVIL WORKS 1921 proposed plan for the improvement of navigation and power for the International Rapids Section of the St. Lawrence River and the proposed method of the regulation of the levels of Lake Ontario, which is an essential feature of that plan. In connection with the study outlined in (a) above, three methods of approach are being utilized by the Board to determine the effect of Gut Dam on the fluctuation of water levels of Lake Ontario; gage relationships, backwater computations and model studies. At the end of the fiscal year draft reports of the studies by gage relationships and by backwater computations were under final review by the Board's working committee, and the model studies have been completed. The Board's working committee has under preparation a report entitled, "Effects on Lake Ontario Water Levels of Gut Dam and Channel Changes in the Galop Rapids section of the St. Lawrence River" which will embody the results of the studies by gage relationships, backwater studies and model studies. A report on the "Effect of Diversions on Lake Ontario Water Levels" dated March 15, 1956, was submitted by the Board to the International Joint Commission by letter of August 24, 1956. With reference to the regulation studies outlined in (b) above, at an executive session of the Commission in New York on Decem- ber 19-20, 1955, the Commission informed the Board that the two Governments had approved the recommended range of mean monthly elevations for Lake Ontario, namely, 244.0 feet (naviga- tion season) to 248.0 feet as nearly as may be; had approved the criteria for operation of the regulatory works as recommended by the Commission's letter dated May 9, 1955, to the Governments; and had approved the use of Plan 12-A-9 for the purpose of cal- culating critical profiles and the design of channel excavations in the International Rapids section of the St. Lawrence River. At a meeting of the Commission in Toronto on January 25, 1956, the Commission advised that no further regulation studies would be required of the International Lake Ontario Board of Engineers, and that such future studies would be conducted by the Inter- national St. Lawrence River Board of Control. The Commission requested that the Lake Ontario Board prepare and submit a re- port on its regulation studies up to that time. The report, entitled "Regulation of Lake Ontario", was submitted to the Commission at its April 1957 meeting in Washington, D. C. In accordance with instructions of the Commission, the Board has under preparation a final report, which will advise the Com- mission relative to the technical engineering matters which the Commission must consider in making a report to the two Govern- ments under the reference of June 25, 1952. The Board submitted progress reports to the International Joint Commission in October 1956 and April 1957. INTERNATIONAL NIAGARA BOARD OF CONTROL Constitution and duties. The Board was established August 19, 1953, by directive of the International Joint Commission, to super- vise the construction, maintenance and operation of the Niagara 1922 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Remedial Works recommended by the International Joint Com- mission in its 1953 report, "Preservation and Enhancement of Niagara Falls." Members of the Board. The Board consists of four members, two representing the United States and two representing Canada. During fiscal year 1957, the United States members of the Board were Brig. Gen. P. D. Berrigan, United States Army, division engineer, North Central Division, Corps of Engineers, chairman, and Mr. F. L. Adams, chief, Bureau of Power, Federal Power Commission. The Canadian members of the Board were Mr. T. M. Patterson, director, Water Resources Branch, Department of Northern Affairs and National Resources, chairman, and Mr. G. H. Thurber, chief, Marine Excavation Division, Harbours and Rivers Engineering Branch, Department of Public Works, Ottawa, Ontario, until Mr. Thurber was replaced by Mr. G. T. Clarke, Chief, Planning and Development, Harbours and Rivers Branch, Department of Public Works, in March 1957, following Mr. Thurber's retirement from Government service. Activities during fiscal year 1957. Assisted by a working com- mittee appointed by the Board in October 1953, consisting of two members each from technical agencies in the United States and Canada, the Board has reviewed and approved the designs and procedures submitted by the construction entities. During fiscal year 1957, no construction contracts were awarded' by the Canadian construction entity, the Hydroelectric Power Commission of Ontario. A hired labor force is being employed to accomplish the construction on the Canadian portion of the7 remedial works. Construction work assigned by the Board to the Canadian construction entity is 99 percent complete at the end of fiscal year 1957. All 13 gates in the Chippawa Pool Control Structure were in service by June 30, 1957. Minor grading and cleanup work remain to be accomplished in the vicinity of the control building and the inscription on the south wall of the control building and the aluminum plaque to be placed at the gate leading to the structure remain to be completed. At the close of fiscal year 1957, the gage house located at the sewage disposal plant of the city of Niagara Falls was 98.2 percent: completed. The gage house is the only uncompleted item of work' on the United States side of the Niagara River in connection with the Niagara Remedial project. The gage will be utilized by the Board in connection with operation of the' Niagara Control structure. The activities of the Niagara Board in connection with construc- tion of the Remedial Works project are virtually completed. Fu- ture activities of the Board will be concerned with operation of the control structure, and supervision of the operation and maintenance of the project. INTERNATIONAL NIAGARA COMMITTEE Constitution and duties. The treaty of 1950 between Canada and the United States concerning uses of the waters of the Niagara MISCELLANEOUS CIVIL WORKS 1923 River was signed on February 27, 1950. By its provisions, limita- tions on the diversion of Niagara River water for power in ac- cordance with article V of the treaty of 1909 are terminated and temporary international agreements for the allocation of waters of the Niagara River for power purposes are replaced. In accord- ance with provisions of article VII of the 1950 treaty, a representa- tive was appointed by each Government who, acting jointly, shall ascertain and determine the amounts of water*available for the purposes of this treaty, and shall record the same and shall also record the amounts of water used for power diversions. By an exchange of notes during January 1955, the two Governments officially designated the representatives appointed in conformance with article VII of the 1950 treaty as the International Niagara Committee. With regard to flows and diversions, the treaty of 1950 became effective October 10, 1950. Under terms of the treaty, all waters in excess of certain minimum flows which are required to maintain the scenic spectacle at Niagara Falls are available for diversions for power and, with the exception of the 5,000 cubic feet per second authorized October 1950 for diversion by Canada, are to be allocated equally between both countries. However, pending availability of sufficient power development on one side of the river, the unused portion of its share of the water may be utilized in spare capacity on the other side. Minimum flows over the falls shall be not less than 100,000 cubic feet per second between 8 a.m. and 10 p.m., e.s.t., from April 1 to September 15, and 8 a.m. to 8 p.m. from September 16 to October 31. At all other times, the flow over the falls shall be not less than 50,000 cubic feet per second. A brief history, regarding the measurement and supervision of diversion of waters from the Niagara River prior to the designa- tion of the representatives appointed under article VII of the 1950 treaty as the International Niagara Committee, is included in the Annual Report for fiscal year 1955. Members of the Committee. The Committee consists of two members, one representing the Dominion of Canada and one representing the United States. During fiscal year 1957, the Canadian representative was Mr. T. M. Patterson, director, Water Resources Branch, Department of Northern Affairs and National Resources, Ottawa, and the United States representative was Brig. Gen. P. D. Berrigan, United States Army, Division Engineer, North Central Division, Corps of Engineers. Operations during the fiscal year. The Committee received daily reports of operation of the seven hydroelectric generating stations on the Niagara River which divert water from the river above Niagara Falls, and the DeCew Falls plant which diverts water from Lake Erie through the Welland Canal. These reports, submitted in the form prescribed by the Committee and showing for each hour the quantities of water diverted by each plant, were checked by the Committee. Monthly and annual summaries were prepared. 1924 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 Biweekly and intermittent inspections of all plants were made by representatives of the Committee, jointly and individually, to obtain independent watt-meter readings of power output and to assure that all provisions of the treaty were complied with. Records of water levels in the Niagara River above and below the falls were obtained by means of self-registering gages. Ten units of the Schoellkopf 3A plant, which were damaged by a rock slide on June 7, 1956, were back in operation at the end of the fiscal year. Diversion of water to the plant is accomplished through the tunnel from the Niagara River to plant forebay. The canal is not being used and flow into it has been cut off by fill. A spillway has been constructed from the downstream end of the tunnel to the top of the escarpment to protect the plant against surges in the tunnel, which can no longer be absorbed by a rise of the water surface in the canal. INTERNATIONAL LAKE SUPERIOR BOARD OF CONTROL Constitution and duties. The Board, established in pursuance of orders issued by the International Joint Commission, May 26, 1914, is charged with the supervision of the operations of all com- pensating works and all power canals and appurtenances with a view to so controlling the outflow from Lake Superior as to main- tain its level as nearly as possible between elevations 602.1 and 603.6 feet above mean tide at New York, and to so controlling the outflow as to prevent the level of the St. Marys River below the locks exceeding elevation 584.5. Members of the Board. The members of the Board for fiscal year 1957 were Brig. Gen. P. D. Berrigan, United States Army, the Division Engineer, North Central Division, Corps of Engi- neers, for the United States and Mr. C. K. Hurst of the Water Resources Branch, Department of Northern Affairs and National Resources until April 18, 1957 when Mr. T. M. Patterson, director, Water Resources Branch, Department of Northern Affairs and National Resources assumed Mr. Hurst's duties on the Board pending appointment of a successor. Operations during the fiscal year. The Board kept in touch during the year with conditions pertaining to the regulation of Lake Superior through representatives of Canada and the United States on the ground, and by means of regular and systematic reports of the water levels in Lake Superior, in channels of the St. Marys River above and below the Sault Locks, and in Lake Huron. Records of discharge at Sault Ste. Marie through the rapids, navigation canals, and power plants were also systemati- cally reported to the Board. A joint inspection was made by the Board on August 3, 1956 at which time the structure in general and the operating parts were found in satisfactory condition. Usual maintenance procedures were followed on the United States gates. No repairs were required thereon during the fiscal year. Changes in the rate of outflow from Lake Superior are directed by the Board as indicated by the rule curve currently in use. Dur- ing the past year the Board has continued the use of the modified MISCELLANEOUS CIVIL WORKS 1925 plan of operation under the Rule of 1949 for the regulation of Lake Superior. Supplies to Lake Superior have been somewhat deficient during the past year. However, at the close of fiscal year 1957 Lake Superior levels correspond closely with those existing at the be- ginning of the fiscal year. It appears that the maximum seasonal crest during the summer of 1957 will approximate 602.4 with continuance of the present trend in supply. LAKE OF THE WOODS WATERSHED The members of the International Lake of the Woods Control Board, the International Rainy Lake Board of Control and the International Prairie Portage Board of Control for the fiscal year were Mr. J. D. McLeod, for Canada, and Col. Otto J. Rohde, Corps of Engineers, for the United States. INTERNATIONAL LAKE OF THE WOODS CONTROL BOARD The convention between the United States and Great Britain proclaimed July 17, 1925, provides for the regulation of the level of the Lake of the Woods in order to secure to the inhabitants of the United States and Canada the most advantageous use of the waters thereof, and of the waters flowing into and from the lake on each side of the boundary between the two countries. The convention also provides for the establishment and mainte- nance of a Canadian Lake of the Woods Control Board to regulate and control the outflow of the waters of the lake, and for the establishment and maintenance of an International Lake of the Woods Control Board, composed of two engineers, one representing the United States and the other representing Canada, to whose approval the rate of total discharge shall be subject whenever the elevation rises above elevation 1,061 or falls below elevation 1,056, sea level datum. Operationsduring the fiscal year. Supervision was maintained and inspections were made to ensure that every effort was being made to comply with the provisions of the convention. INTERNATIONAL RAINY LAKE BOARD OF CONTROL The convention between the United States and Canada, ratified by the United States Senate August 30, 1940, provides in part that: "The International Joint Commission * * * is hereby clothed with power to determine when emergency conditions exist in the Rainy Lake watershed, whether by reason of high or low water, and the Commission is hereby empowered to adopt such measures of control as it may seem proper with respect to existing dams at Kettle Falls and International Falls, as well as with respect to any existing or future dams or works in boundary waters of the Rainy Lake watershed, in the event the Commission shall determine that such emergency conditions exist." On June 8, 1949, the Commission issued an order to the owners of the dams at the outlet of Namakan Lake and Rainy Lake, which 1926 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1957 provided for a method of regulation as recommended by the International Rainy Lake Board of Control. The order provides for certain levels during the various seasons of the year as well as control of outflows, with the view of securing the most advanta- geous use of the water in total to the various interests. Operations during the fiscal year. Inspections were made, basic data compiled, and engineering reports were submitted to the Commission. INTERNATIONAL PRAIRIE PORTAGE BOARD OF CONTROL The Prairie Portage Board of Control was formed by the Inter- national Joint Commission for the purpose of furnishing it with technical advice regarding the suitability of the dam structure at Prairie Portage, Lake County, Minn. After approvel of the plans by the Department of the Army, and the International Joint Com- mission, the Board has been retained to advise the Commission further regarding progress of construction and regarding any other matters which might arise concerning this project. The United States Forest Service constructed a cofferdam before World War II but postponed work on the project during the war. Work has not been resumed except that some repairs were made to the cofferdam in the fall of 1955 to maintain better stages on the chain of lakes above. The board inspected the cofferdam and site in July 1956. INTERNATIONAL KOOTENAY LAKE BOARD OF CONTROL Constitution and duties. The Board was organized to secure compliance with the provisions of the orders of the International Joint Commission dated November 11, 1938, and August 5, 1949, relating to the construction and operation of control works by the Consolidated Mining and Smelting Co. of Canada, Ltd., through the West Kootenay Power and Light Co., Ltd., in and adjacent to the channel of the Kootenay River, and the regulation of the levels of Kootenay Lake in the Province of British Columbia. Members of the Board. The members of the Board for the fiscal year were Mr. H. T. Ramsden, Water Resources Branch, Department of Northern Affairs and National Resources, Van- couver, B. C., and Mr. A. F. Paget, Comptroller of Water Rights, Department of Lands and Forests, Victoria, B. C., for Canada; and Col. R. J. B. Page, Corps of Engineers, and Mr. T. R. Newell, United States Geological Survey, Boise, Idaho, for the United States. Operations during the fiscal year. One meeting of the Board was held and a report dated September 12, 1956 entitled "Report to the International Joint Commission by the International Koote- nay Lake Board of Control re the Proposed Highway Crossing of Nicks Slough" was submitted to the Commission. Investigations and visits to the area were made by individual members of the Board. The annual report was submitted to the Commission. MISCELLANEOUS CIVIL WORKS 1927 INTERNATIONAL OSOYOOS LAKE BOARD OF CONTROL Constitution and duties. A special board of engineers was constituted to ensure compliance with the provisions of the order of the International Joint Commission dated July 12, 1943, direct- ing investigation of high water conditions, on the Okanogan River and studies of the relationships between certain obstructions, com- plained of in an application by the State of Washington, and the levels of Osoyoos Lake. The Board was enlarged from 2 to 4 mem- bers by an order of the Commission dated September 12, 1946, to carry out the provisions of the order relative to the operation of the Zosel Dam.
