MISSISSIPPI RIVER BETWEEN THE MISSOURI RIVER AND MINNEAPOLIS, MINN. (ROCK ISLAND DISTRICT) For report on this improvement see page 1437. 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 Bureau Creek Valley to Rock River, near Colona, thence in the bed of Rock River to the rapids near Milan, and thence to the Mississippi 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 follow- ing 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 estimated cost of new work, revised in 1902, is $8,911,- 551.12. The estimated cost for maintenance and operation, re- vised in 1950, is $264,000 annually.

It is located in the south end concrete, and steel; at lock 30 there are crib dams across the north and south channels of of the Sterling Dam and about 600 feet below the guard lock of the Illinois and Mississippi Rock River. The north dam has a 60-foot opening and has been superseded by a con- Canal (feeder section). crete power dam a short distance below; the south dam adjoining lock 30 has been rein- forced with concrete laid in the water. RIVERS AND HARBORS-ROCK ISLAND, ILL., DISTRICT 1461 Local cooperation.-Fullycomplied with. Terminal facilities.-None. Operations and results during fiscal year.-The work performed during the fiscal year consisted of maintenance and operation of the project. Locks, bridges, buildings, canal banks, roadways, tele- phone lines, and fences were repaired; seep ditches and aqueducts were cleaned out; and brush and weeds were cut and burned along the canal right-of-way, all by hired labor. Maintenance dredging at one location in the canal was performed by Govern- ment plant and hired labor, a total of 10,362 cubic yards of mate- rial having been removed. The costs during the fiscal year were $206,313.22 for operating and care. The expenditures were $216,- 058.27. Condition at end of fiscal year.-The existing project was com- pleted in 1918. All locks, dams, aqueducts, buildings, and other appurtenances are in fair condition. Tabulation under paragraph "Existing project" gives data regarding the principal features of construction. At the end of the fiscal year, the controlling depth in the main canal was 3.5 feet (in Rock River section near Milan), and in the feeder canal was 4 feet. These depths have restricted the use of the canal to lightly loaded barges and to pleasure craft. The bottom width of the canal is 52 feet and the width at water surface is 80 feet, except at aqueducts where the width is 40 feet, and at locks, 35 feet. Since April 29, 1948, in order to maintain the maximum possible service with the limited funds available, the canal has been open to all types of navigation only on Thurs- day and Friday of each week with prior arrangements being made at least one day in advance, and has been open to commercial tows on other weekdays with prior arrangements being made at least seven days in advance of the date passage is desired. The total cost to June 30, 1950, from regular funds was $10,- 157,521.49, of which $7,580,143.41 was for new work and $2,577,- 378.08 was for operating and care. The expenditures were $10,- 149,893.99. The costs and expenditures from Emergency Relief Funds for removal of snags and stumps in Rock River pool were $25,000, all new work. In addition, the sum of $4,143,282.27 was expended between April 1895 and June 30, 1936, on the operating and care of the works of improvement under the provisions of the permanent indefinite appropriation for such purposes. Proposed operations.-The balance unexpended at the end of the fiscal year, amounting to $20,649.39, plus an anticipated allot- ment during fiscal year 1951 of $163,000, a total of $183,649.39, will be applied as follows: Accounts payable, June 30, 1950 .......... :...... ......... $7,627.50 Maintenance (operating and care) (hired labor): Operations ................................ $90,000.00 Ordinary repairs .......................... 73,000.00 Improvements and reconstruction ............ 13,021.89 Total ........................................... . 183,649.39 The additional sum of $75,000 can be profitably expended dur- ing fiscal year 1952, for maintenance, by exclusive of lock opera- tion which is scheduled to be discontinued. 1462 REPORT OF CHIEF OF ENGINEERS, U.

Previous projects.-Adopted by the River and Harbor Act of January 21, 1927. (For further details see p. 1132, Annual Re- port 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 carry- ing the flood waters 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 connection 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, at an estimated cost of $87,500 for new work. The estimated cost of maintenance, revised in 1950, is $10,000 annually. The existing project was adopted by the River and Harbor Act approved 'July 3, 1930 (Rivers and Harbors Committee Doc. 19, 71st Cong., 2d sess.). The latest published map is in the project document. Local cooperation.-Fullycomplied with. Terminal facilities.-None. Operations and results during fiscal year.-Hired labor forces cut brush and willows on the banks of Mill Creek and South slough, performed minor dredging and snagging, and operated spillway gates. An allotment of $35,000 in addition to an allotment of $2,000 for regular maintenance, was made during the fiscal year for maintenance operations in cleaning out accumulated silt from the channels of Mill Creek and South slough to relieve flood hazards at the village of Milan, Ill. Preparation of contract plans and speci- fications, by hired labor, was completed during the fiscal year. RIVERS AND HARBORS-ROCK ISLAND, ILL., DISTRICT 1463 The costs during the fiscal year were $7,051.08 for maintenance. The expenditures were $7,184.22. Conditionat end of fiscal year.-The existing project was com- pleted in 1932. Maintenance channel clearing, by contract, of the channels of Mill Creek and South slough, which have been partial- ly filled with accumulated silt, has not been started.

Location.-This project is located in the basin of The Sny, a former by-channel 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 bottom lands consists of four major diversion channels (diversion of McCraney and Hadley Creeks; Kiser Creek; Horton and Dutch Creeks; and Six Mile and Bay Creeks) to conduct the run-off from the uplands drainage area directly to the Mississippi River; construction of two retarding reservoirs (one each for Fall-Austin and Pigeon Creeks) ; improvement of the Sny channel to collect bottom-land run-off; construction of five pumping stations to drain the five areas into which the district would be divided by the four major stream diversions; construction to effect internal drainage of areas from which natural drainage will be blocked by the new construction; construction of a closing levee to exclude backwater up The Sny; and the construction of remedial works necessitated by the improvement. The estimated Federal cost for construction of the project, revised in 1950, is $16,170,000. The project was authorized by the Flood Control Act approved July 24, 1946, substantially in accordance with the recommendations of the Chief of'Engineers in House Document No. 713, Seventy-ninth Congress, second ses- sion. The latest published map is in the project document. Local cooperation.-Section 3 of the Flood Control Act ap- prov,ed June 22, 1936, applies. See page 8 for requirements. In addition, local interests will be required 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, have been furnished, but have not been forwarded for approval since said assurances must be accompanied by evidence that local interests have the financial ability and legal authority to fulfill the requirements of local cooperation. 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 coun- ty court. Action by the drainage district in this matter must be deferred until completion of detailed plans. It is estimated that after the drainage district has been fur- nished with the detailed plans and rights-of-way maps, it will then 939127-51-vol. 2----3 1466 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 take the Sny Island levee drainage district approximately one year to spread the assessments, damages, and benefits; secure court approval of the project; levy the special assessments; issue the drainage bonds, and secure the necessary financial assistance required in order to furnish evidence that it has the financial ability and legal authority to carry out the local-cooperation re- quirements. It may reasonably be considered that subsequent to that time it may take approximately two years, and possibly long- er, for the drainage district to actually fulfill the requirements of local cooperation. Operations and results during fiscal year.-Preliminary plan- ning, including field surveys, design and estimates, and prepara- tion of detailed plans, by hired labor, was continued during the fiscal year. The costs during the fiscal year were $108,934.45 for new work. The expenditures were $116,164.52. Condition at end of fiscal year.-Construction has not been started. Preliminary planning of the project, by hired labor, is about 38 percent complete. The total cost to June 30, 1950, was $356,669.77 for new work. The expenditures were $352,247.76. Proposed operations.-The balance unexpended at the end of the fiscal year, $2,172,552.24, less an anticipated revocation of $2,100,000, a balance of $72,552.24, will be applied as follows: Accounts payable, June 30, 1950 ................... ........ $4,422.01 New work: Continue preliminary planning (hired labor) (July 1950 to June 1951) ...................................... 68,130.23 Total for all work ................................... 72,552.24 No additional funds are needed for the work presently sche- duled during the fiscal year 1952.

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 lo- cated 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 Geodetic 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-fill 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 em- bankment by a gravity-type, non-overflow, 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 con- crete founded on bed-rock 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 10- foot gated conduits will extend through the spillway section and will discharge into the spillway stilling basin. The non-overflow 1468 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 concrete sections of the dam at each end of the spillway will be of the gravity type, firmly keyed into the foundation rock, and the right-bank section will contain one 16-foot round pen stock. Ini- tially, the pen stock will be plugged at either end and no power installation is to be provided. The drainage area above the dam site is 12,250 square miles. With pool at full-flood-control elevation, the reservoir area will be about 68,000 acres; the reservoir will contain approximately 1,850,000 acre- feet of water at that height; 1,800,000 acre-feet of the reservoir will be allotted to flood-con- trol purposes; the remaining 50,000 acre-feet will be used for a conservation 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, revised in 1950, is $59,632,000, including $47,734,000 for construction and reloca- tions, and $11,898,000 for lands and damages. The Flood Control Act of December 22, 1944, authorized to be appropriated certain monies 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 No. 651, Seventy-eighth Congress, second session. The Red Rock project was made eligible for selection as a unit of the general comprehensive plan for flood control and other purposes in the Upper Mississippi River Basin under the aforementioned Flood Control Act of June 28, 1938. The latest published map is in House Document No. 651, Seventy-eighth Congress, second session. Local cooperation.-None required.

For further details see page 1888 of the Annual Report for 1915, and page 1098 of the Annual Report for 1938. Existing project.-This provides for the reconstruction of the five original reservoir dams, viz., Winnibigoshish, Leech Lake, Pokegama, Sandy Lake, and Pine River, and the construction of Gull Lake Reservoir. The estimated cost revised in 1928, exclusive of amount ex- pended on previous projects, was $895,000. The latest approved (1950) estimate of cost of maintenance and operation of the reservoirs is $45,000 annually. The above dams are of solid con- crete 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 recommended in House Document No. 413, Sixty-fourth Congress, first session, and was ordered by Congress in the River and Harbor Act of July 27, 1916. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1899 For reconstruction of 4 of the 5 original dams, and surveys to determine the extent of lands over- flowed by the reservoirs.

Terminal facilities.-None. Operationsand results during fiscal year.-The reservoirs were operated as required and repairs and improvements made to the various structures. Repair items included repair and redecorating of the interior of the dwelling at Winnibigoshish Dam, the office building at Poke- gama Dam and exterior of dwellings and service buildings at Pine River Dam. Improvements included installation of new water heaters and furnaces in the office buildings at Winni- bigoshish, Pokegama, Sandy Lake and Gull Lake Dams; anti- friction bars in stoplog recesses at Pokegama Dam; a recorder gage well in Sandy Lake Reservoir; renewal of the apron with concrete and timber at Pine River Dam; riprapping the left bank of the discharge channel below Winnibigoshish Dam; and im- proving the recorder well in Leech Lake Reservoir. It was nec- essary to protect the dam and dikes with sand bags at Sandy Lake Dam during the emergency created by exceptional high water at that site during May and June 1950. The precipitation in the reservoir area in the calendar year 1949 was about normal in the first 6 months but totaled 31.7 inches for the year 7.2 inches over normal. In the first 6 months of 1950 the precipitation exceeded normal by 3.7 inches. This excess precipitation, combined with deep frost and late break-up fol- lowed by rains, resulted in a very high percentage of spring run-off and the greatest inflow of record to the reservoirs in the period 20 April to 31 May. The Mississippi River at Aitkin reached an all time high of 19.46 feet on 20 May, 2.46 feet above the previous high stage; Sandy Reservoir reached a new high of 17.51 feet on 19 May, 2.46 feet above the previous high; and Winnibigoshish and Leech Reservoirs which were practically closed during the high water period at Aitkin were very high, causing considerable damage to shore line property. The opera- tion of the Headwaters Reservoirs is estimated to have reduced the peak stage at Aitkin by about 1.3 feet. The stage at Aitkin was in excess of the 12-foot flood stage for a period of 57 days. Dur- ing the year inflow was about 2,707,100 acre-feet and about 1,966,700 acre-feet was discharged, resulting in a net gain in storage of about 740,400 acre-feet. 1490 REPORT OF CHIEF OF ENGINEERS, U.

MINNESOTA RIVER, MINN. Location.-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 improvement from the Mississippi River to Shakopee (25.6 miles) to obtain a channel with 4 feet of water from the Mississippi River to Shako- pee, which will accommodate vessels of 3-foot draft. The estimate of cost for new work, made in 1892, was $10,000, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $2,- 500. 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 channel between the mouth and Savage, Minn., mile 13.2, be 1492 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 dredged to a depth of 9 feet, and the Secretary of War under authority contained in section 4 of the River and Harbor Act ap- proved 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, a dock 650 feet in length with warehouse adjacent, with additional mooring space 1,300 feet in length. Operationsand results during fiscal year.-Preliminarysurveys for maintenance were carried on by hired labor at a cost of $1,- 262.55, and expenditure of $1,364.65. Condition at end of fiscal year.-The existing project was com- pleted in 1931. Additional channel dredging (see "Local coopera- tion"), completed in July 1943, provides: 'A channel with mini- mum 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 restricted 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 Shakopee for drafts not in excess of 3 feet. The total costs under the existing project to June 30, 1950, were $85,848.34, being $12,730.69 for new work and $73,117.65 for maintenance. Expenditures were $85,844.15 In addition, the cost and expenditure from contributed funds was $139,670.91 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.

Local cooperation.-Local interests for Hudson Harbor are re- quired 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 con- struction of the project and subsequent maintenance, when and as required; (b) hold and save the United States free from dam- ages due to the construction of the project; (c) provide and main- tain 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 (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 such facilities shall be open to all on equal terms. Local interests have not been formally 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 river bank to the water, and a terminal for the receipt of petrol- eum products, inoperative at present. 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 1494 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 be made on the banks. Facilities are considered adequate for exist- ing commerce. Operations and results during fiscal year.-Maintenance channel dredging involving removal of a total of 11,167 cubic yards of material at mile 6.3, removal of 125 snags in the reach from Still- water to Taylors Falls, and preliminary dredging surveys were carried out by Government plant and hired labor. Costs and expen- ditures for the year were $7,283.42 for maintenance. Condition at end of fiscal year.-All new work was completed in 1930 except the recently authorized harbor at Hudson. The ex- tension 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; from mouth to Stillwater, 9 feet. The total costs and expenditures to June 30, 1950, were $304,446.64 being $150,409.50 for new work and $154,037.14 for maintenance.

The Texas Co. and Barnly As- sociates, Inc., own oil terminals on the left bank at miles 1.1 and 1.25, respectively. The city of La Crosse owns and operates a public terminal on the left bank 1.4 miles above the mouth. The latter consists of a timber trestle 300 feet in length with plank deck, designed for truck and crawler crane operation. The facil- ities are considered adequate for existing commerce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The existing project was about 87 percent complete. Channel dredging completed provides 9-foot depth for a width of about 300 feet throughout the full length of the project except for contraction to 100 feet at the Chicago, Mil- waukee, St. Paul & Pacific Railroad bridge, mile 1. Work remain- ing to complete the project consists of removal of obstructions at various points outside the dredged area to clear the channel to full project width. The total costs and expenditures under the existing project to June 30, 1950, were $67,584.96 for new work. Proposed operations.-The balance unexpended June 30, 1950, amounting to $1,000 was reallocated to another project. No work is scheduled for fiscal years 1951 or 1952. 1496 REPORT OF CHIEF OF ENGINEERS, U. S.

Estimated (1950) annual cost of maintenance (operating and care) for this unit is $8,800. 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 latest published map is in the project document (H. Doc. 185, 81st Cong., 1st sess.) Local cooperation.-The improvements, with the exception of the proposed Orwell Reservoir on the Otter 'Tail River, are sub- ject to the conditions that local interests will (a) 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; (b) hold and save the United States free from damages due to the construction and subsequent maintenance of those works; (c) maintain the channels after completion in accordance with regulations pre- scribed by the Secretary of the Army; and (d) make at their own expense all necessary changes to utilities, highways, and bridges including approaches. No local cooperation is required in connec- tion with the proposed reservoir on the Otter Tail River. Immediately following authorization of the basin project, local interests from the entire basin signified their desire that construc- tion of Orwell Reservoir be given first priority. At a subsequent meeting of the Tri-State Waters Commission with representatives from the three states involved, and local interests, a priority was established for the local flood-protection units authorized in the basin project. Actual priority will depend largely upon ability of local interests to fulfill local cooperation requirements. Local in- terests have not been formally advised in writing of the require- ments of local cooperation. Those in the Wild Rice and Marsh, Mustinka and Sand Hill areas have furnished assurances. These were approved December 30, 1949, June 16, 1950, and January 9, 1950, respectively. Lands required for construction on the Wild Rice River have been furnished and those on the Mustinka River and tributaries are being acquired. Local agencies have been formed in the Rush and Otter Tail River areas. It is expected that these agencies will furnish assurances in the near future. After informal outline of requirements of local cooperation to local in- FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1501 terests in the Sheyenne River area, a meeting was held by them on January 27, 1949, at which objections were raised which served to delay the organization of a sponsoring agency. Operations and results during fiscal year.-Advance planning was carried on for Orwell Reservoir, and for Otter Tail, Wild Rice and Marsh, Sheyenne, Sand Hill, Rush, and Mustinka River features of the project as well as surveys for detailed planning on the main stem at Grand Forks-East Grand Forks, Fargo-Moor- head, and Wahpeton-Breckenridge. A contract initiating construc- tion on the Wild Rice River has been awarded, but no work has been done. Bids for construction on the Mustinka River and tri- butaries have been opened, but contract has not been awarded due to lack of fulfillment of local cooperation.

PEMBINA RIVER RESERVOIR, N. DAK. Location. 'The Pembina River dam site is located on the Pem- bina River, about 9 miles upstream from Walhalla, N. Dak. and 96.9 miles above the mouth. The Pembina River has its head- waters in southern Manitoba, Canada, and flows southeasterly to the vicinity of Elwood, N. Dak., then easterly to join the Red River of the North about 2 miles south of the international boundary. Its length is 275 miles, of which 115 are in the United States. (For general location of dam site see U. S. Geological Survey map of North Dakota.) Existing project.-The plan of improvement provides for the construction of an earth-fill dam, having a height of about 64 feet above the stream bed and a length of 1,040 feet, including a con- crete spillway section having a 150-foot wide crest at an elevation 23.5 feet below dam crest, with a sluiceway decreasing in bottom width from 150 to 50 feet, and a 6.5-foot square inside dimension concrete conduit under the dam, with a 4-foot square inside dimension concrete control tower superimposed on the conduit at the upstream toe of the dam. The reservoir created by the dam will have a capacity of 19,000 acre-feet. The reservoir storage capacity of 7,000 acre-feet below spillway crest will be used to provide a minimum flow of 5 second-feet to meet the water-con- servation needs. Benefits of an intangible nature which would result include a more adequate supply of water for fire protection; alleviation of danger of epidemics to people and livestock; exten- sive recreational benefits; and improvement in the general wel- fare and social security of the people residing near the reservoir site and in the river basin below the dam. The latest approved estimated cost (1950) to the United States for new work is $632,000. The approved estimated annual cost of maintenance is $5,000 for operating and care of the dam. The project was authorized by the Flood Control Act approved December 22, 1944 (H. Doc. 565, 78th Cong., 2d sess.). The latest published map is contained in the project document. 1504 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Local cooperation.-The improvement is subject to the condi- tions that local interests make a cash contribution of $235,200, toward the construction cost; and 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 neces- sary for the construction of the project; maintain the channel be- low the reservoir; make necessary changes in roads, bridges, and utilities; hold and save the United States free from claims for damages due to the construction works; limit future construction of dams or other works below the reservoir; and establish pre- ventive measures to control contamination of the river. Local interests have not been formally advised in writing of the above requirements but have formally expressed inability to com- ply with the present requirements as outlined; however, they have secured authority for restudy of the project. Operations and results during fiscal year.-Additional studies have been carried on by hired labor with funds authorized for this project. Costs for the year were $1,008.06 and expenditures were $1,769.43. Condition at end of fiscal year.-Additional studies have been substantially completed and work on detailed plans is about 32 percent complete.

TONGUE RIVER RESERVOIR, N. DAK. Location.-The Tongue River dam site is located on the Tongue River, about 13 miles upstream from Cavalier, N. Dak., and about 60.2 miles above the confluence of the Pembina and Tongue Rivers. Tongue River, the main tributary of the Pembina River, has its source in Cavalier County in northeastern North Dakota and flows northeasterly approximately 100 miles to join the Pembina River near the eastern boundary of North Dakota. (For general location see U. S. Geological Survey map of North Dakota.) FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1505 Existing project.-The following features are included in the plan of improvement: An earth-fill dam, having a height of about 40 feet above the stream bed and a total length of 2,090 feet, in- cluding spillway section; the spillway section composed of steel pile cells and grouted stone, with 180-foot wide crest at an eleva- tion 13.5 feet below dam crest, and a sluiceway decreasing in bottom width from 180 to 50 feet; and a 36-inch diameter conduit under the dam, with a concrete control tower superimposed on the conduit at the upstream berm, and a separate concrete trash rack tower at the upstream toe of the dam. The reservoir created by the dam will have a capacity of 6,400 acre-feet at spillway design flood stage and a storage capacity of 3,000 acre-feet below spillway crest. It will provide for reservoir control of floodwaters and for a minimum release of 3 second-feet during 9 years out of 10 in which spring run-off would fill the reservoir to storage capacity. The latest approyed estimated cost (1950) to the United States for new work is $706,700. The approved estimated annual cost of maintenance is $5,000 for operating and care of the dam. The project was authorized by the Flood Control Act approved December 22, 1944 (H. Doc. 565, 78th Cong., 2d sess.). 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 $68,600, to- ward the construction cost; and 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 neces- sary for the construction of the project; maintain the channel be- low the reservoir; make necessary changes in roads, bridges, and utilities; hold and save the United States free from claims for damages due to the construction works; limit future construction of dams or other works below the reservoir; and establish pre- ventive measures to control contamination of the river. Local interests have not been formally advised in writing of the above requirements. Restudy of this project has been included with that of the Pembina River project. Operations and results during the fiscal year.-Preliminaryin- vestigations for preparation of detailed plans were carried on by hired labor at a cost of $974.67 for new work. Expenditures were $1,010.08. Condition at end of fiscal year.-Only preliminary investiga- tions for the preparation of detailed plans have been accomplished, work on which is 45 percent complete. The costs to June 30, 1950 were $23,632.00. Expenditures were $23,637.69. Proposed operations.-The balance unexpended June 30, 1950, $12,362.31 plus accounts receivable $5.69, totals $12,368. This amount will be applied to detailed plans. No work is scheduled for the fiscal year 1952. 1506 REPORT OF CHIEF OF ENGINEERS, U. S.

RED LAKE RIVER, MINN. INCLUDING CLEARWATER RIVER, MINN. Location.-The works covered by this project lie along the up- per 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 north- western 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 meander- ing 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; modi- fication of the existing stop-log 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, one stop-log bay; raising 6.9 miles of highway at west end of Lower Red Lake to prevent overtopping; and rectification, clear- ing, and enlargement of 37.5 miles of the channel of the Clear- water River so as to provide sufficient channel capacity between river mile 41.5 near Plummer, Minn., and mile 79.1 upstream from the mouth of Ruffy Brook. The channel improvements will elimi- nate a large percentage of the flood damages resulting from over- flow of the rivers and will provide adequate channels in Red Lake and Clearwater Rivers to carry the discharge from drainage FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1507 ditches. Modification of the existing control works at the outlet of Lower Red Lake will provide for a discharge capacity of 1,000 cubic feet per second through the structure when the lake is at normal elevation (1,174.0) and will insure the release of sufficient water to provide water-supply and pollution-abatement benefits to municipalities along Red Lake River, and along the Red River of the North below the mouth of Red Lake River. The latest approved estimated cost (1950) to the United States for new work is $4,108,000. The approved estimated annual cost to the United States for maintenance is $8,500 for operating and care of the control structure. 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 condi- tions that responsible local interests give assurances satisfactory 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 con- struction 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 down- stream from Lower Red Lake, Clearwater Lake, or Mud Lake unless authorized by the Department of the Army. The 5-year period within which local interests will be required to furnish assurances satisfactory to the Secretary of the Army that the required cooperation will be furnished has not been ini- tiated by a formal written notice. However, an existing drainage district reorganized by order of court has voluntarily furnished all assurances except those on pollution which were furnished by the Minnesota Water Pollution Control Commission. All of these assurances were accepted October 3, 1947. A contribution of $33,- 220 was received from local interests in July 1948. All rights-of-way and easements outside the Indian Reservation have been acquired by the Red Lake Drainage and Conservancy District as local agency, and permit to the Government for con- struction has been granted, except as to areas along the south side of the Clearwater River adjacent to the Reservation. On October 22, 1947, the Red Lake Indian Council adopted a resolution authorizing the Office of Indian Affairs, Interior Depart- ment, to carry out necessary transfer of authority to the Depart- ment of the Army. Following completion of a report by the United 1508 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 States Fish and Wildlife Service, the Indian Council passed an- other resolution on October 28, 1948, which indicated the Coun- cil's desire for preservation of march areas within the reservation. However, upon further study, the council on April 17, 1949, re- vised their resolution of October 28, 1948, in favor of a modified plan within the reservation. On December 2, 1949, the Acting Sec- retary of the Interior authorized construction work along the Red Lake River right-of-way within the reservation, subject to cer- tain conditions and subject to formal application for necessary easements and rights-of-way. Formal application was forwarded to the Secretary of the Interior on February 10, 1950. Notice of action has not been received. As it was construed by the acting Secretary of the Interior that existing resolutions did not cover the Clearwater River, a new resolution was secured from the Tri- bal Council specifically including work along the Clearwater River. Operations and results during fiscal year.-Design was con- tinued by hired labor. Contracts for channel excavation and clear- ing on the Red Lake River were under way as follows: Stage 1. about 12 miles of channel at the lower end of the improvement was completed; Stage 2, an additional 7 miles was continued; Stage 3, a further 5.3 miles of channel (through the westerly 4.5-mile width of the reservation), and Stage 4, 3.2 miles of channel imme- diately below the outlet structure were initiated. A contract for Clearwater River Stage 1, about 10 miles of channel excavation and clearing at the lower end of the improve- ment, was completed. Work on Stage 2, an additional 12.5 miles of Clearwater River channel improvement extending to the Indian Reservation, was initiated, the contract having been awarded in the prior fiscal year. Cost for the year for new work were $579,252.28 United States funds and $20,682.01 contributed funds, as follows: $13,618.96 for design, engineering, etc. and $586,315.33 for construction. Cost by hired labor, $15,107.26; by contract, $584,827.03. Expendi- tures were $692,971.59, being $672,289.58 from United States funds and $20,682.01 from contributed funds. Condition at end of fiscal year.-Detailed plans and flowage surveys are completed. Checking titles of land furnished by local interests is complete on the Red Lake River and on Stages 1 and 2 of the Clearwater River. Design is about 57 percent complete. Construction was initiated in February 1948 on the Red Lake River and a total of about 20 miles of channel excavation has been completed under four contracts completed or in progress. Con- struction was initiated in October 1948 on the Clearwater River and about 12 miles of channel excavation has been accomplished under the two contracts completed or in progress. The project as a whole is about 38 percent complete. Completed portions of the channels are in good condition. Work remaining to complete the project includes completion of channel improvements on the Red Lake and Clearwater Rivers, alteration of dam at the outlet of Lower Red Lake, raising road at lower end of Lower Red Lake and appurtenant work including necessary alteration of bridges. FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1509 The total cost of the existing project to June 30, 1950, was $1,243,493.77 of which $1,210,273.77 were Federal funds and $33,- 220.00 contributed funds.

HOMME RESERVOIR AND DAM, N. DAK. Location.--The dam site is located on the South Branch of the Park River, about 4 miles upstream from Park River, N. 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 inter- national 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 earth-fill dam, having a height of about 66 feet above the stream bed and a length of 865 feet; a 5-foot in- side 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- FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1511 control protection will be afforded by the reservoir of 7,100 acre- feet capacity which will be created by the dam, and the reservoir storage capacity of 3,650 acre-feet below spillway crest (1080.0) will be 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 will be provided at the request of local interests. The latest approved estimated cost (1950) to the United States for new work is $1,231,600. The latest approved estimated annual cost of maintenance is $6,300 for operating and care of the dam. The project was authorized as "Park River Reservoir" by the Flood Control Act approved December 22, 1944 (S. Doc. 194, 78th Cong., 2d sess.). The latest published map is contained in the project document. The project was redesignated "Homme Reservoir and Dam" by Public Law 435, Eightieth Congress, Second session, approved March 5, 1948. Local cooperation.-The improvement is subject to the condi- tions that local interests make a cash contribution of $40,000 to- ward 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 con- struction works; limit future construction of dams below the reser- voir; and prevent the discharge of raw sewage into the river by municipalities. An additional cash contribution will be required for additional work that has been requested by local interests. Although local interests were not advised formally in writ- ing of the above requirements, they have voluntarily submitted assurances for approval, which were approved by the Secretary of War on April 29, 1947. Local interests have furnished the cash contribution of $40,000 and all the required lands. The cities of Park River and Grafton have also furnished a total of $16,220 required for additional work requested by them for a water supply outlet. Operationsand results during fiscal year.-Design and prepara- tion of master plan for reservoir management and public use facilities were substantially completed. Stage 2, construction of spillway, embankment closure and appurtenant work, was initi- ated in July 1949 and is 60 percent complete. Some delay was encountered due. to abnormal weather conditions and the contract was suspended for the winter season. A contract was awarded for construction of beaches in pool area, but very little work has been done due to abnormal high water conditions. Due to protracted high water, an incompleted portion of the embankment closure providing for overflow was overtopped causing erosion and sub- sequent breaching of this section of the embankment resulting in loss of pool. The end monolith of the right wingwall of the stilling basin was also damaged and various areas were eroded or under- mined requiring repair. Repairs have been initiated. 1512 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19 5 0 Costs for the year for new work were $380,695.78 Federal funds as follows: $8,805.54 for design, engineering, etc., and $371,- 890.24 for construction. Cost by hired labor, $13,771.73; by con- tract $366,924.05. Expenditures were $309,338.34 Federal funds. Condition at end of fiscal year.-Preliminary work including designs has been completed except for designs pertaining to public use facilities. Master plan for the latter work is substantially com- plete. Construction was initiated in April 1948 and the outlet works, a major portion of the embankment and spillway excava- tion, and the pool clearing are complete. Contract for construction of spillway, embankment closure and appurtenant work is in progress. Contract for construction of beaches has been awarded but no work has been done. Condition of existing structures is good except for that portion damaged by floods in the spring of 1950. The project as a whole is 73 percent complete. The total cost of the existing project to June 30, 1950 was $967,381.15; of which $911,161.15 was Federal funds and $56,- 220.00 contributed funds.'

BALDHILL RESERVOIR, 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 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 earth fill dam, having a height of about 61 feet above the stream bed 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 will be at elevation 1,252 and will be surmounted by three stand- ard design Tainter gates each 40 feet long and top elevation at 1,267. A gate-controlled 3-foot diameter conduit will be provided in each of the two piers. The dam will create a reservoir of 70,700 acre-feet capacity and will control the run-off 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 diversion 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 (1950) to the United States for new work is $2,694,500. The estimated annual cost for maintenance is $12,000 for operating and care of the Baldhill Dam. The project was authorized by the Flood Control Act approved December 22, 1944 (S. Doc. 193, 78th Cong., 2d sess.).

ARMY, 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 toward the first cost of the reservoir and until responsible local agencies have given assurances satisfactory to the Secretary of War that they will (a) hold and save the, United States free from damages due to the con- struction works; (b) bear the expense of all necessary alterations of utilities, roads, highways, and bridges; (c) construct, operate, and maintain the Fargo diversion dam and diversion ditch im- provements in accordance with plans and regulations to be ap- proved by the Secretary of War; (d) maintain the channels below the reservoir in satisfactory condition for the flow of water re- leased from storage, to include the prevention of encroachments on the carrying capacity of the channel which would unduly inter- fere with the conveyance of floodwater; and (e) establish and enforce suitable regulations to prevent pollution of the waters of Sheyenne River. The Bureau of Reclamation and the Corps of Engineers have cooperated on studies comparing the merits of the Sheyenne Res- ervoir (to be constructed by the Bureau farther upstream as part of the proposed Missouri-Souris diversion project) with the Bald- hill Reservoir. The results of these studies indicate that construc- tion of Baldhill Reservoir will fulfill an immediate need but would not entirely satisfy the ultimate downstream water requirements, and that the Baldhill Reservoir would also provide a measure of flood control which the Sheyenne Reservoir cannot supply because of its upstream location. Based on these results, the North Dakota Water Conservation Commission has furnished all local coonera- tion assurances except the one for construction of the Fargo diver- sion dam and ditch which has been furnished by the City of Fargo. Assurances were approved by the Secretary of War on June 26, 1947. The required cash contribution of $208,000 has been fur- nished. Operations and results during fiscal year.-Design, studies for a master reservoir management and public use plan, and land acquisition were carried on by hired labor. About 3,708 acres of land in fee and easements on 93 acres were obtained during the year. Construction of spillway and control works (Stage 2) was completed in August 1949 and the closure section (Stage 3) started in July 1949 was completed on 20 June 1950, both by con- tract. A contract for Stage 2 clearing comprising an area about 11 miles in length and 1,800 feet wide to the vicinity of the Great Northern Railway bridge started in December 1949 is 31 percent complete. On July 29, 1949, the final closure was made in the dam and all inflow was impounded. The pool began to rise and on October 12. 1949, it had reached elevation 1,238 mean sea level (1929 adj.), the elevation of the invert of the two-gated culverts through the dam. On the latter date the first discharge passed through the culverts. The gates continued in the wide open posi- tion until the spring break-up. The average elevation of the pool for the period October 12, 1949, through March 22, 1950, was approximately 1,239.50, with the maximum at elevation 1,239.90 and a maximum discharge of about 40 second-feet. The spring rise FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1515 began on March 23, and the gated spillway, elevation 1,252, was overtopped on April 7. At the request of local interests and the Governor of North Dakota and with local interests assuming cer- tain responsibility for damages within the flowage area, the spill- way gates were placed in emergency operation on April 16, 1950. Except for a small sag during the period April 27-May 6, the pool continued to rise through May 14, 1950, when a crest elevation of 1,269.49 mean sea level was reached. The outflow was controlled so that the total flow at Valley City remained below damage stage. The maximum outflow from Baldhill was about 3,050 second-feet. The crest storage amounted to about 91,000 acre-feet, of which 89,000 acre-feet were directly the result of the spring run-off. It is estimated that the flood crest at Valley City was reduced about 6 feet. An estimated savings of about $1,538,000 was realized on the Sheyenne River, mostly in the vicinity of Valley City. Following the crest, the outflow from the dam was main- tained at near the maximum permissible rate until June 6 when the discharge was reduced to about 2,200 second-feet. Inasmuch as clearing operations had not been completed, the pool was allowed to continue to fall to facilitate celaring operations and had reached elevation 1,251.7 by the end of the fiscal year. Total costs for new work for the year were $523,053.14 Federal funds as follows: Advanced planning including designs, $57,- 250.64; land acquisition. $178,324.08; construction, $287,478.42. Costs by hired labor, $239,243.42: by contract $283,809.72. Ex- penditures for new work were $674,835.77 Federal funds. Costs for operating and care during the year were $337.83; no expendi- tures were made. Condition at end of fiscal year.-Preparationof detailed plans and flowage surveys are complete, design is about 95 percent com- plete, land acquisition and preparation of master plan for public use facilities are in progress. About 6,916 acres of land in fee, and easement on 94 acres have been acquired. About 1,479 acres of land in fee and easement remain to be acquired. Construction was initiated in July 1947, and spillway, control works and em- bankment are in place and are in good condition. The project as a whole is about 84 percent complete. The dam was operated on an emergency basis commencing on April 6, 1950, but the pool will be lowered in order to complete land acquisition and clearing. It is expected that the dam will be placed in permanent operation in the spring of 1951. Total costs to June 30, 1950 were $2,436,317.22; $2,435,979.39 for new work of which $2,227,979.39 were Federal funds and $208,000 contributed funds, and $337.83 for operating and care. Total expenditures were $2,214,021.02 Federal funds and $208,- 000, contributed funds. Proposed operations.-The balance unexpended June 30, 1950, $124,978.98, plus anticipated allotment of $318,650.00 for new work and $25,500.00 for maintenance allotted during fiscal year 1951, a total of $469,128.98, will be applied as follows: 1516 REPORT OF CHIEF OF ENGINEERS, U.

FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1517 15. LAKE TRAVERSE AND BOIS DE SIOUX RIVER, 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 United States Geological Survey map of Minnesota. Existing project.-The plan of improvement provides for use of Lake Traverse as a flood-control and water-conservation reser- voir and for channel improvement in the river below the lake. It in- cludes construction of a dam near White Rock, S. Dak., at the north end of Lake Traverse, a structure at the Reservation High- way crossing for control of the upper section of the Reservoir, 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 northward 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 be- tween two sections of rolled-fill embankment with a total length of approximately 14,400 feet from high ground on the Minnesota side to high ground on the South Dakota side. This dam supple- mented by channel improvement of the Bois de Sioux River down- stream and an embankment approximately 5,000 feet long at the south end of Lake Traverse for the protection 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 abut- ment walls behind which compacted fill with soil-cement slab pave- ment 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 should restore Lake Traverse to its former natural condition as a habitat for an abundance of wildlife and fish. The latest approved estimate of cost (1950) is $1,474,000, of which $1,115,200 is for construction and $358,800 for land and damages. The latest (1950) approved estimate of annual cost of maintenance is $9,000. 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 operated in accordance with the established plan. Following a dry spring which left both Reservation and White Rock pools below conservation levels at the beginning of the fiscal year, heavy rains early in July accounted for a rise in both pools which resulted 1518 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 in a peak storage of 124,300 acre-feet or 11,800 acre-feet of flood storage above conservation levels. High evaporation, subnormal rains, plus a small discharge averaging less than 50 second-feet in July and 10 second-feet in August 1949 depleted the flood storage by August 21. Continued evaporation resulted in a further loss of storage through Decem- ber 10 when about 105,000 acre-feet of storage remained, 7,500 acre-feet below conservation levels. The storage remained at sub- stantially this value throughout the winter until spring break-up began on about March 24, 1950. The resulting peak storage of 200,600 acre-feet included 88,100 acre-feet of flood storage above conservation levels and was second only to the May 1943 flood. Record breaking high water downstream from Grand Forks and disastrous flooding prevented discharge prior to May 31, 1950 in order not to aggravate flood conditions in the lower reaches of the, Red River. As a result 160,000 acre-feet of storage, 47,500 acre-feet of flood storage above conservation level, still remained in the reservoirs at the end of the fiscal year even with an average discharge of over 600 second-feet, a high rate of evaporation and subnormal rainfall during the month of June. It is estimated that the crest of the Red River of the North at Wahpeton was reduced about one foot. A savings of about $45,000 in flood damages was realized in the reach from White Rock Dam to the mouth of the Bois de Sioux River and in the vicinity of Wahpeton-Breckenridge as a result of the operation of the project. Costs for the year were $9,300.04 for operating and care by hired labor, being $8,182.73 for opeiations and $1,117.31 for miscellaneous repairs and improvements. Expenditures were $9,693.06. Condition at end of fiscal year.-The existing project was com- pleted in June 1948. Fee title to 1,278.48 acres and easements on 5,952 acres of land have been acquired. The White Rock Dam and Reservation control structure were in operation and the earth dam, dikes, channels and appurtenances were in good condition. The roadways across the White Rock Dam and Reservation con- trol structure were open to public travel. The total costs under the existing project to June 30, 1950, were $1,420,539.35, being $1,332,200.00 for new work and $88,- 339.35 for operating and care. The expenditures were $1,419,- 876.25. Proposed operations.-The balance unexpended June 30, 1950, $2,823.75, plus accounts receivable, $26, and an anticipated allot- ment of $8,150 during fiscal year 1951, a total of $10,999.75 will be applied as follows: Accounts payable June 30, 1950 .............................. $689.10 Maintenance (operating and care) : Operations ................................. $9,510.65 Ordinary repairs ................... 600.00 Improvement and reconstruction ............... 150.00 Real estate management ...................... 50.00 Total operating and care ............................ 10,310.65 Total ............................................. 10,999.75 FLOOD CONTROL-ST.

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 St. Paul. The Mississippi River in this area flows in a general south- westerly 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 alignment between miles 1,064.0 and 1,040.4 on the Mississippi River, being a channel slightly less than 6 miles in length with bottom width of 88 feet and 1 on 21/2 side slopes; a short channel permitting the Little Willow River to enter the main diversion channel about a mile above the natural junction, this channel being about 1,500 feet in length with bottom width of 12.5 feet and 1 on 11/2 side slopes; erosion control structures at the mouth of the Little Willow diversion and five other points where drainage from the north would enter the main diversion channel; and appurte- nant work. The improvements will alleviate the flood condition and improve drainage in and near Aitkin, Minn. The latest approved (1950) estimate of cost to the United States for new work is $1,767,500. 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 1520 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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) bear the expense of all necessary construction or alterations of utilities, roads, highways and bridges; (d) maintain all works after completion in accordance with regulations pre- scribed by the Secretary of the Army; and (e) prevent future encroachments in the flood plain of the Mississippi River within the limits of the project. The responsibility for local cooperation has been assumed by the Aitkin County Flood Control Association. Local interests have not been formally requested to furnish assurances. Operations and results during fiscal year.-Preparationof de- tailed plans was initiated by hired labor. Costs for the year were $845.33. Expenditures were $361.33. Condition at end of fiscal year.-Preparationof detailed plans is 2 percent complete. No construction has been initiated. Total costs to June 30, 1950, were $845.33 for new work. Expenditures were $361.33. Proposed operations.-The balance unexpended June 30, 1950, amounting to $24,638.67, plus an anticipated allotment $47,305 for fiscal year 1951, a total of $71,943.67 will be used for payment of accounts payable ($484), completion of detailed plans and for preparation of contract plans and specifications, by hired labor, July 1950 to June 1951. No work is scheduled for fiscal year 1952.

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 location see United States. Geological Survey map of Minnesota. FLOOD CONTROL-ST. PAUL, MINN., DISTRICT 1521 Existing project.-Constructionof 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 present plan of improvement provides for completion and maintenance 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 Work Projects Administra- tion 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 flood waters 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 embank- ment connecting with high ground on either side of the valley. The Marsh Lake Dam consists of a 112-foot concrete spillway, and two sections of dredged earth fill totaling approximately 8,500 feet in length, including an auxiliary 90-foot grouted riprap overflow spillway. The Chippewa River flood diversion dam consists of a cdncrete fixed crest structure supporting a highway bridge, and a section of earth fill through which is provided a conduit for dis- charge of low water flow. The diversion channel for passing flood- waters of the Chippewa River into the Lac qui Parle Reservoir is 3,500 feet in length cut through a natural ridge separating the river and an arm of the lake and includes a six-span concrete sub- merged weir, also supporting a bridge, which allows a reverse flow from the lake. A rolled earth fill 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 includes 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 between Lac qui Parle Lake and Granite Falls consists of rock removal, snag removal, and cut-offs at various locations to provide for increasing the bank-full capacity of the channel. The project, with reservoir capacity of about 94,500 acre-feet for flood control above normal elevations of the two conservation pools, will provide pro- tection for agricultural lands against summer floods. Storage of 58,500 acre-feet for conservation purposes provided below normal elevations of conservation pools will result in improved lake levels for recreation and game conservation in addition to providing for increased low water flow downstream for agricultural interests and for sewage disposal at Granite Falls. 1522 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The latest approved (1950) estimated cost to the United States for completion of the project, is $419,300 for construction and $532,500 for lands and damages. The estimated annual cost of maintenance is $12,000. Local cooperation.-None required. Operations and results during fiscal year.-Investigation of fee titles and flowage easements, and negotiations with the State of Minnesota relative to transfer of the project and accompanying land acquisition and with the Chicago, Milwaukee, St. Paul & Pacific Railroad relative to operation of the project were carried on by hired labor. Negotiations with the State of Minnesota were consummated except for final certification by the State. The agreement with the railroad has been approved by the railroad and is awaiting approval of the. Secretary of the Army. A con- tract was awarded for alterations to the Chippewa and Lac qui Parle Dams, but initiation of work has been withheld. Total costs for the year were $20,598.36 for new work. Expenditures were $17,720.91. Condition at end of fiscal year.-The existing project as a whole was approximately 40 percent complete. Construction was started in September 1941, and the following work has been completed: Lac qui Parle Dam improvements; Minnesota River channel im- provements; bituminous surfacing, Lac qui Parle Dam spillway; Marsh Lake Dam improvements; Great Northern Railway bridge alteration and grade raising; and stage-recorder houses. A con- tract has been awarded for construction of a new concr'ete sill, apron and Tainter gate at the Chippewa River Dam and for new bulkheads on the Lac qui Parle Dam, but no work has been done. Work remaining to be initiated to complete the project includes: channel excavation at mile 277, snag removal and clearing on the Minnesota River, and riprap protection and road on Marsh Lake Dam. Design on the remaining items is in progress. Negotiations toward transfer of the project from the State of Minnesota to the United States are in progress, and operation by the United States will be started after final execution of the docu- ment effecting transfer which bears the date of June 28, 1950. Final execution of this document will be made early in fiscal year 1951.

DRY RUN, IOWA Location.-In northeastern Iowa, on Dry Run, a tributary of the Upper Iowa River at Decorah, Iowa. (See U. S. Geological Survey map Decorah quadrangle, Iowa.) Existing project.-The Flood Control Act approved June 22', 1936, authorized a flood-retention reservoir and channel enlarge- ment downstream for the protection of the city of Decorah. The Flood Control Act approved August 18, 1941, Public Law 228, Seventy-seventh Congress, first session, modified the project to provide for diversion of Dry Run into the Upper Iowa River, a levee system along the Upper Iowa River in Decorah for protec- tion of adjacent Iroperty against augmented high-water flow, raising a section of railroad tracks and State Highway No. 9, and 1524 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 necessary alterations to bridges and protection to existing struc- tures in the vicinity. The diversion is to be accomplished by an earth dike across Dry Run at a point about 1 mile southwest of Decorah and a diversion channel 3,200 feet in length from that point through high ground to the Upper Iowa River on the north. The project will provide complete protection to residential, in- dustrial, and commercial areas totaling about 260 acres within the city limits of Decorah against the maximum probable flood on Dry Run and against a flood on Upper Iowa River equivalent to about twice the maximum of record. Floods on Dry Run creating serious damages have occurred about once every 11 years. The latest (1950) approved estimated Federal cost for new work is $1,706,900. Local cooperation.-Local interests are required to furnish all lands, easements, and rights-of-way without cost to the United States, hold and save the United States free from damages due to construction of the works, and provide maintenance and opera- tion of the project subject to the regulations prescribed by the Secretary of the Army for such maintenance and operation. The legislature of the State of Iowa has passed legislation enabling the city of Decorah to furnish required assurances. On April 8, 1947, the city of Decorah was formally notified of the as- surances required and of the initiation of the 5-year period for furnishing them. Assurances were accepted July 8, 1947. Lands have been furnished and the sum of $42,765.80 has been paid by local interests for alteration of Twin Bridge and other work.

For description, see page 1149, Annual Report for 1932. Practically the entire length of the section from Kansas City to the mouth is contained within the State of Missouri. Previousprojects.-The first appropriation for improvement by regulation was made in the River and Harbor Act of June 18, 1878. The original plan for comprehensive improvement was adopted by the River and Harbor Act of August 2, 1882, modified by River and Harbor Acts of July 5, 1884, September 19, 1890, and June 13, 1902. For further details see page 1891 of Annual Report for 1915 and page 1153 of Annual Report for 1938. Existing project.-This provides for a channel of 9-foot depth and width not less than 300 feet, to be obtained by revetment of banks, construction of permeable dikes to contract and stabilize the waterway, cut-offs to eliminate long bends, closing of minor channels, removal of snags, and dredging as required. Length of section under improvement (mouth to upper end of Quindaro Bend) is 386.2 miles'. Ordinary and extreme fluctuations of stage are 16 and 38 feet, respectively. The estimated cost for new work, revised in 1950, is $113,297,- 100, exclusive of amounts expended on previous projects. The esti- mated cost for annual maintenance is $2,000,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents July 25, 1912 Project adopted for securing a permanent navigable H.

RIVERS AND HARBORS-KANSAS CITY, MO., DISTRICT 1533 funds upon authorized works where such would be in the interest of navigation, is authorized by the River and Harbor Act of March 4, 1915. The Secretary of the Army has approved the general prin- ciple of cooperative construction on the Missouri River below Kan- sas City on the basis that 25 percent of the cost of any special installation shall be paid by the United States and 75 percent by the local interests. The total amount contributed by local interests in cooperation with the United States from 1918 to June 30, 1950, was $675,662.- 80, of which $8,647.11 was returned to contributors. Terminal facilities.-Facilities for transferring grain, petrol- eum products, and other commodities are maintained at various locations on this section of the river.

The total cost of new work was $2,133,335.51. Maintenance.-This work consisted of the repair, by contract, of 5,104 linear feet of dikes including 1,230 linear feet of rock- filled dike and 10,318 linear feet of revetment, at a total cost of $365,686.19; and the accomplishment, by hired labor. of the fol- lowing: Removal of 2,706,830 cubic yards of material from 10 lo- calities by the U. S. dredges Mitchell and Clark, at a total cost of $216,962.47; the repair of 38,496 linear feet of dikes of 45,621 linear feet of revetment at a total cost of $1,533,325.90; paving of 26,407 linear feet of accretion including 23,190 linear feet of accretion paving by rock fill at a total cost of $324,133.14; con- struction of a chute closure structure at a total cost of $49,990.27; removal of 60 snags at a total cost of $3,183.76; engineering, de- sign, and surveys, including channel surveys, in connection with maintenance work, at a total cost of $186,624.80; stream gaging for special studies and working data at a cost of $23,515.92; mark- ing channel for navigation at a cost of $130,235.31; and mainte- nance of the Liberty Bend Cut-off highway bridge at a cost of $236.37. The total cost of all maintenance work was $2,833,894.13. The total costs for the fiscal year were as follows: New work Maintenance Total Regular funds-...-.---._____ ... . ... . . ..... $2, 133, 335. 51 $2, 833, 894.13 $4,967,229.64 The total expenditures were $4,843,425.85. Condition at end of fiscal year.-The existing project was about 85 percent complete at the end of the fiscal year, based on the present approved estimate of cost. The physical extent of work accomplished was 1,766,766 linear feet of dikes, 1,205,024 linear feet of revetment, 29,499 linear feet of abatis, 27,493 linear feet of bank protection, 35,842 linear feet of retards, 27,111 linear feet of levees, five revetment spillways, excavation of 7,537,789 cubic yards of material in the construction of pilot canals, removal of 110,028 linear feet of existing structures, dredge fills totaling 1,546,493 cubic yards, removal of 432,664 cubic yards of rock, removal of 81,382,936 cubic yards of material by dredging, and re- moval of 5,439,461 cubic yards of material in the improvement of bank alinement. The majority of river control structures in sev- eral localities in this section of the river are either completely de- stroyed or in a very poor state of repair due to the curtailment of work during the war, the very frequent and severe floods dur- ing and since the war, and the scarcity of funds since the war to prosecute the necessary repair work at a most efficient rate. Al- though additional dikes and revetment are required to attain the project dimensions, a channel with a minimum depth of 61/2 feet RIVERS AND HARBORS-KANSAS CITY, MO., DISTRICT 1585 and a minimum width of 200 feet is available through out the navigation season, which covers approximately the period from March 15 to November 30. The controlling depth throughout this section of the river on June 30, 1950, was generally in excess of 8 feet due to the high river stage at which time there was an average discharge at Kansas City, Mo., of approximately 84,800 cubic feet per second. The practical draft at ordinary stages of the river is 61/2 feet. This section of the river has been used for commercial navigation since June 1935. The total cost of the existing project to June 30, 1950, was as follows: New work Maintenance Total Regular funds.__ ____- __------ - _____ -__ _ $78, 985, 381. 85 $37, 321,036.43 $116, 306, 418. 28 Emergency relief funds..--_- ------------- 1, 375, 243.49 133, 756. 51 1, 509, 000.00 Public works funds-.... . . __--__-.__ .. ___-____- __---6, 468, 490.38 --------------- 6, 468, 490. 38 Total ...... ...... ... . ..... ..... ..... 86, 829, 115. 72 37, 454, 792. 94 124, 283, 908. 66 The total expenditures under the existing project to June 30, 1950, were $124,295,399.01 ($116,317,908.63 regular funds, $6,- 468,490.38 public works funds, and $1,509,000 emergency relief funds).

OSAGE RIVER, MO. Location.-This river, rising in eastern Kansas, flows easterly 516 miles in sinuous bends to the Missouri River, 129 miles above its mouth and 14 miles below Jefferson City. Existing project. This provides for a lock and dam and for open-channel work consisting of wing dams and training walls, removal of obstructions, and dredging between the mouth and Warsaw to obtain a uniform depth of 3 feet. The length of sec- tion included in the project is 171.2 miles, and (Osage River and Lake of the Ozarks 1948 mileage) consist of two parts, mouth to Bagnell Dam (Federal Power Commission project No. 459 at mile 81.7 above the mouth) and Bagnell Dam to legal head of naviga- tion (immediately below Warsaw). Ordinary and extreme fluctua- tions of stage on the Osage River below Bagnell Dam are 15 and 41 feet and on the Lake of the Ozarks, formed by Bagnell Dam, are 10 and 30 feet. The estimate of cost of new work, revised in 1928, is $250,000, exclusive of the lock and dam, for open-channel work as far as the mouth of the Niangua River (112.8 miles above the mouth of the 1538 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Osage River). The latest (1936) approved estimate of cost for annual maintenance is $18,500, including $6,000 for operating and care of lock and dam. The following table shows the principal features of the lock and dam included in the project: Lock and dam 1, Osage River Nearest railroad station ........................ Osage City, Mo., 6 miles.

June 26, 19341 Operating and care of the lock and dam provided for with funds from War Department appropriations for rivers and harbors. 1 Permanent Appropriations Repeal Act. For latest published maps see House Document 91, Seventy- third Congress, first session. Terminal facilities.-On the Lake of the Ozarks formed by Bag- nell Dam, there are several marine ways and drydocks operated by private interests which are capable of handling any boats now operating or likely to be operated on the lake. There also exist a few docks which are open to the public, and numerous private docks. These facilities adequately fullfill existing needs. On the Osage River below Bagnell Dam there are several small boat docks and facilities for transferring sand and gravel main- tained by private interests which adequately fulfill existing needs. Operations and results during fiscal year.-Work consisted of the operation and care of the lock and dam as required for the passage of small craft and passenger boats at a total cost of $7,- 844.73 and a total expenditure of $8,081.78. There were 65 lock- ages for 64 small craft and one passenger boat which passed through the lock. RIVERS AND HARBORS-KANSAS CITY, MO., DISTRICT 1539 Condition at end of fiscal year.-Considerabledrift and silt has accumulated in the downstream portion of the lock, the lock and gates show minor leaks, the machinery for operation of the lock is worn and antiquated, and a portion of the water lines needs replacement. Except for the construction of two wing dams, one in 1925 and one in 1926, the open-channel work was completed sufficiently in 1919 to provide reasonable accommodations for the commerce actually using the channel. Upon the completion of Bagnell Dam in 1931, navigable depths in excess of the project depth were made available at all times on the portion of the project upstream from mile 81.8. Navigation activities on the latter section have increased considerably with the development of the Lake of the Ozarks as a recreational area. The controlling depth from the, mouth of the river to mile 26, or about 14 miles above the lock and dam, is 3 feet and drafts of 2 feet over this section are practicable. The controlling depth from mile 26 to Bagnell Dam is 2 feet and drafts in excess of 18 inches are not practicable. On the Lake of the Ozarks, depths of 10 feet or more are available at ordinary stages of the lake from Bagnell Dam to the mouth of Cole Camp Creek, about 80 miles above the dam, decreasing to approximately 5 feet in the vicinity of Warsaw, Mo. The topography adjacent to the lake is such as to form various coves in the lake, of which many have dependable channels for navigation for considerable distance above their confluence with the main stem of the lake. The total cost of the existing project to June 30, 1950, was $1,309,392.66 from regular funds, of which $658,075.71 was for new work, $543,847.22 was for maintenance, and $107,469.73 was for operation and care of the lock and dam. The total expenditures were $1,309,471.48 from regular funds. In addition, the sum of $190,561.10 was expended between July 1, 1912 and June 30, 1935 on the operation and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes. Proposedoperations.-The unexpended balance of $576.45 plus accounts receivable of $78.82 and an anticipated allotment for the fiscal year of 1951 of $10,000 will be applied during the fiscal year 1951 as follows: Maintenance (July 1, 1950, to June 30, 1951) (Operations and care): Accounts payable ....................................... .....

S. ARMY, 1950 The existing project was authorized by the following flood- control acts : Acts Work authorized Documents June 22, 1936 Levees and flood walls for the protection of the Kan- H. Doe. 195, 73d Cong., 2d sess. sas City at an estimated construction cost not to exceed $10, 000, 000, estimated cost of lands and damages, $8, 000, 000. Dec. 22, 1944 Modified and extended the project to provide con- H. Doec. 342, 78th Cong., 1st sess. struction of cut-offs and protection for additional areas at an estimated additional cost of $8, 445, 000. July 24, 1946 Authorized the Chief of Engineers to include neces- sary railroad bridge and approach alterations as a Federal responsibility. The estimated cost, revised in 1950, is $44,514,000 of which $41,389,000 is the Federal cost and $3,125,000 is for lands and damages 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, existing levees and flood walls of the Argentine district are of sufficient height to protect the district from the design flood but due to materials used in constructing the levees their stability would be seriously threatened by the design flood. It is proposed to strengthen these levees, install necessary facilities for control of underseepage and construct a pumping plant. Armourdale unit.-The earth levee along the left bank of the Kansas River from mile 6.7 to mile 2.9' is of sufficient heights to provide protection from the design flood. The project provides for raising the existing levee from mile 2.9 to 2.8'; constructing a new levee riverward of the existing flood wall from mile 2.8 to 1.7'; replace existing flood wall with a new flood wall from mile 1.7 to 1.01; construct a new levee from mile 1.0 to 0.7'; and con- struction of new flood wall including the replacement of a short section of existing wall from mile 0.7 to 0.3'. The, downstream end of the new wall will connect with the southern terminus of the existing Fairfax District levee. Central Industrial unit.-Beginning at the south end of the Armour-Swift-Burlington bridge over the Missouri River, mile 376.9,2 the existing and proposed protection for the district extends upstream along the right bank of the Missouri River to the mouth of the Kansas River, mile 378.82, 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 plan of improvement consists of the construction of concrete flood walls and earth levees to protect the portion of the unit lying in the State of Missouri, and the raising of existing structures and construction of new concrete flood walls and earth 1 Above mouth of Kansas River. 2 Above mouth of Missouri River. FLOOD CONTROL-KANSAS CITY, MO., DISTRICT 1551 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, flood walls, 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, Kans., water and light plant (mile 385.3)' downstream to the mouth of the Kansas River, thence along the left bank of the Kansas River to the vicini- ty of the intercity viaduct (mile 0.3) ;'pumping plants; and ap- purtenant works. Subsequent to the construction of the above work, the elevation of the design flood has been raised due to a decrease in the width of the floodway, necessitating the raising of the Fairfax-Jersey Creek flood-protection works. North Kansas City unit.-Beginning at a point northwest of the Kansas City, Mo., municipal waterworks, the existing and pro- posed protection for the unit extends downstream along the left bank of the Missouri River for a distance of about 6.55 miles and opposite approximately Missouri River mile 375; thence north along the rigth bank of Rock Creek to the Wabash Railroad right- of-way, a distance of about 0.8 mile; thence northwesterly along a drainage ditch to high ground northeast of the Kansas City, Mo., municipal waterworks, a distance of about 1.6 miles. The plan of improvement consists of raising and realinement of existing levees and a railroad embankment and the construction of new earth levees and a concrete flood wall 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 proposed 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 existing and proposed protection for the district extends down- stream 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 proposed improvements will consist of levees and a flood wall 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 South- ern Railroad bridge (mile 0.84)1 to the mouth; and removal of major obstructions from the bed of the main channel of the Kansas River between the Argentine bridge (mile 5.13)' and the mouth. Bridge and approach alterations, Kansas River unit.-In order to permit the free passage of drift during flood periods, it is coh- 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 1Above mouth of Kansas River. 2 Above mouth of Missouri River. 1552 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 permanent raising of four highway and three railroad bridges, and provision of facilities for the temporary raising during flood periods of three other railroad bridges.

Replacement of the left-bank ap- proach fills to the Armour-Swift-Burlington and Hannibal bridges by approach spans is provided in the plans and is 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 tirdl'er from the area riverward of the existing Birmingham drainage district levee along the left bank of the Missouri River between mile 370 and mile 363 and of removing brush from the area river- ward of the proposed East Bottoms levee along the right bank between mile 373.5 and mile 367.8.2 Birmingham unit.-In order to provide protection to the Bir- mingham district, various upstream sections of the Birmingham levee, between mile 371.7 and mile 365.52 will be raised by the addition of rolled fill and downstream sections will be strength- ened. Blue Valley Industrialunit.-The work contemplated under this unit consists, of the construction of levees and flood walls at ap- proximately present Big Blue River mile 5.4 to provide flood pro- tection for a section of the Big Blue River Valley. Liberty Bend cut-off.-The work under this unit consists of the construction of a main cut-off channel beginning at mile 363.7 and extending downstream to mile 358.5 ;2 a second cut-off chan- nel from mile 358.5 to mile 357;2 and the construction of a new highway bridge where the main cut-off channel intersects United States Highway No. 71 (bypass) which at present crosses the Missouri River north of the proposed cut-off at mile 361.2 Local cooperation.-See page 8 for requirements.

MISSOURI RIVER, KANSAS CITY TO SIOUX CITY Location.-The Jefferson, Madison, and Gallatin Rivers conjoin at Three Forks, Mont., to form the Missouri River, which flows southeasterly 2,464.41 miles across or along seven States to the Mississippi River, 17 miles above St. Louis. The river is the boundary between the States of Missouri, Kan- sas, Nebraska, and Iowa. For description, see page 1149, Annual Report for 1932. Previous projects.-Under the River and Harbor Act of August 14, 1876, the first regulation works were constructed at St. Joseph and Nebraska City, but a project for systematic river improve- ment was not adopted until August 2, 1882, modified by the River and Harbor Acts of July 5, 1884, September 19, 1890, and June 13, 1902. For further details see page 1893, Annual Report for 1915, and page 1175, Annual Report for 1938. Existing project.-This provides for a channel of 9-foot depth and width not less than 300 feet, to be obtained by revetment of banks, construction of permeable dikes to contract and stabilize the waterway, cut-offs to eliminate long bends, closing of minor channels, removal of snags and dredging as required. Length of section under improvement (upper end of Quindaro Bend to Sioux City) is 376.3 miles. The ordinary fluctuation is about 14 feet and the extreme fluctuation about 38 feet. The estimated cost of new work, revised in 1950, is $151,200,400 exclusive of amounts expended on previous projects. The esti- mated cost of annual maintenance is $2,500,000. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-OMAHA, NEBR., DISTRICT 1585 Acts Work authorized Documents 1 Jan. 21, 1927 Appropriation of $12,000, 000 authorized for the H.

Operations and results during fiscal year.-New work: This work consisted of construction, by contract, of 21 pile dikes total- ing 8,150 linear feet, 1 rock dike totaling 300 linear feet, 34 lengths of revetment totaling 29,051 linear feet, 2 foundation mattresses totaling 1,939 linear feet, strengthening and replacing 20,496 linear feet of pile dikes and revetment by placement of 72,- 939 tons of stone in addition to other features of work, and re- moving 121 linear feet of pile dike, at a total cost of $2,348,828.51; 1586 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 construction, by hired labor, of 16 pile dikes and 3 dike extensions totaling 8,654 linear feet, and 13 lengths of revetment totaling 9,451 linear feet, and removal of 975 linear feet of existing pile dikes and revetment at a total cost of $518,623.85; engineering, design, and surveys, at a cost of $59,232.67; and engineering in- vestigations, at a cost of $3,000. The total cost of new work, all prosecuted with regular funds, was $2,929,685.03. In addition to completed works, there is in progress of construction, by contract and hired labor, 4 dikes to total about 1,133 linear feet, and 1 piece of revetment to total about 1,075 linear feet. Maintenance: This work consisted of construction, by contract, of repair and replacement of 10,357 linear feet of pile dikes, and 17,611 linear feet of revetment; and 9,115 linear feet of accretion paving, at a total cost of $1,074,888.55; the accomplishment, by hired labor, of repair or replacement of 28,932 linear feet of pile dikes, and 34,042 linear feet of revetment; removal of 433 linear feet of pile dikes, construction of 2 chute closures totaling 733 linear feet, and stabilization of 6,118 linear feet of accreted bank line on the permanent alinement by the placement of cast paving, at a total cost of $2,054,684.50; removal of 2,791,585 cubic yards of material from the channel at 7 localities, and 39,737 cubic yards of material from the entrance to the Florence Boat Basin by the U. S. dredge Lewis; removal of 1,107,770 cubic yards of material from 3 localities by the U. S. dredge Clark; and the removal of 220, 452 cubic yards of material from the channel at 1 locality, and 55,556 cubic yards of material from the entrance to the Flor- ence Boat Basin by the U. S. dredge Chittenden, at a total cost for dredging of $221,907.06; removal of 2,000 cubic yards of stone from the channel by dragline at a cost of $3,597.77. The cost of engineering, design, and surveys in connection with hired labor maintenance work was $104,590.88, and the cost of engineering investigations was $3,000. Other miscellaneous costs, all charged to maintenance, were: Stream gaging for special studies and working data at a cost of $12,620.72; navigation aids at a cost of $28,287.32. The total cost of all maintenance prosecuted with regular funds was $3,503,576.80. The total cost for the fiscal year was $6,433,261.83, of which $2,929,685.03 was for new work, and $3,503,576.80 for mainte- nance. The expenditures were $6,601,301.00, of which $2,887,- 162.66 was for new work, and $3,714,138.34 was for maintenance, all from regular funds. Condition at end of fiscal year.-The work on the entire project Kansas City, Mo. (upper end of Quindaro Bend), to Sioux City, Iowa, was approximately 65 percent complete at the end of the fiscal year, based on the present approved estimate of cost. Kansas City, Mo., to Rulo, Nebr.--The work between Kansas City, Mo (upper end of Quindaro Bend), and Rulo, Nebr., was approximately 81 percent complete at the end of the fiscal year. The majority of river control structures in several localities in this section of the river are either completely destroyed or in a very poor state of repair due to the curtailment of work during the war, the very frequent and severe floods during and since the war, and RIVERS AND HARBORS-OMAHA, NEBR., DISTRICT 1587 the scarcity of funds since the war to prosecute the necessary re- pair work at a most efficient rate. At moderate stages of the river a channel with a minimum depth of 6 feet is available throughout this section. The controll- ing depth throughout this section of the river on June 30, 1950, was in excess of the project depth of 9 feet due to the extreme high river stage at which time there was an average discharge at St. Joseph, Mo., of 78,700 cubic feet per second. The practical draft at ordinary stages of the river is 6 feet. Commercial naviga- tion was inaugurated on this section of the river in May 1939. During the war years such navigation declined until October 1946 when common carrier transportation service was inaugurated. The work remaining to be done to complete this section of the project consists principally of the construction of additional dikes and revetment. Rulo to Omaha, Nebr.-The work between Rulo, Nebr., and Omaha, Nebr., was approximately 71 percent complete at the end of the fiscal year. The majority of river control structures in several localities in this section of the river are either completely destroyed or in a very poor state of repair due to the curtailment of work during the war, the very frequent and severe floods dur- ing and since the war, the severe attack by ice this past winter and the scarcity of funds since the war to prosecute the necessary repair work at a most efficient rate. A navigable channel 6 feet in depth and 200 feet in width, with a reasonable additional width around bends, is maintained during the navigation season. Com- mercial navigation has existed in this section since May 1939. Dur- ing the war years commercial navigation declined until October 1946 when common carrier transportation was inaugurated. Omaha, Nebr., to Sioux City, Iowa.-The work between Omaha, Nebr., and Sioux City, Iowa, was approximately 50 percent com- plete at the end of the fiscal year. Loss of alinement and progres- sive destruction of control works is in progress in various parts of this section of the river, due to natural deterioration of the struc- tures coupled with curtailment of work during the war, inade- quate funds for new work and maintenance since the war, and several extreme high waters. In addition, other losses are occur- ring due to concave banks being unprotected at the time of cur- tailment of work. Work possible with the limited funds available during the fiscal year has made some progress toward the restora- tion of the channel at the particular locations to which applied but losses at other locations have been such that very little improve- ment of the channel for the section as a whole has resulted. Chan- nel conditions limit practical drafts to 31/2 feet from Sioux City to Omaha, Nebr., during ordinary navigable discharges, and 51/2 eet during high water periods. Under the existing project for systematic work on the 9-foot channel, the work accomplished includes 1,059,679 linear feet of revetment for permanently fixing the banks. 2,159,209 linear feet of pile dikes, 10,142 linear feet of 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 1588 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 channel widths, construction of five impermeable structures to close off auxiliary channels, construction of 48,237 linear feet of asphalt revetment, effecting three channel cut-offs and removal of 83,429,215 cubic yards of material dredged from the channel to obtain project depth and width.

DISASTER OPERATION "SNOWBOUND" During the winter months of January, February, and March 1949, unprecedented snow storms and cold waves in the Western States caused so much distress in this area that the President of the United States authorized various agencies of the Government to spend available funds to meet the emergency. Without the immediate participation by the various agencies, there would have been tremendous loss of life and also tremendous loss of live- stock, both cattle and sheep. Fortunately, these agencies were able to move in with bulldozers and other equipment to open the roads and by means of airplanes of both the Army and Navy to fly in supplies, thereby holding to a minimum the loss of lives and livestock. Funds in the amount of $5,510,000 have been allotted to the Omaha district to defray expenses incurred under Operation "Snowbound". The cost to the Federal Government of Operation "Snowbound" in the Omaha district was $5,106,029.97, and the expenditures were $5,106,029.97. The unexpended balance at the end of the fiscal year 1950 is $403,970.03, of which $36,332.65 will be needed to pay outstanding claims, provided they are granted, leaving a balance of $367,- 637.38.

Included in the comprehensive plan is the following project in the Denver district: Estimated Project Federal cost Cherry Creek Dam and Reservoir........----------- --.--------.----------------------..... $15, 700,000 Details of this project are presented in the individual report. The act of December 22, 1944, further provides that it shall be the duty of the Secretary of War to prescribe regulations for the use of storage allocated for flood control or navigation at all reservoirs constructed wholly or in part with Federal funds pro- vided on the basis of such purposes, and the operation of any such project shall be in accordance with such regulations. Local cooperation.-None required. Operations and results during fiscal year.-Detailed under Cherry Creek and tributaries, Colorado. Condition at end of fiscal year.-Detailed under Cherry Creek and tributaries, Colorado. Proposed operations.-The operations proposed during fiscal year 1951 and the funds needed to be appropriated in fiscal year 1952 for projects on which work is under way are given in the individual reports. Under sections 7 and 9 of Public Law 534. Flood Control Act approved December 22, 1944,. the Corps of Engineers is responsible for detailed scheduling of operations of storage capacity reserved for or assigned to flood control in reser- voirs constructed by the Bureau of Reclamation, as well as those constructed by the Corps of Engineers. Funds in the amount of $5,000 have been allotted for the scheduling of flood-control opera- tions during fiscal year 1951. The sum of $10,000 will be necessary during fiscal year 1952 for such scheduling of flood control opera- tions. FLOOD CONTROL--DENVER, COLO., DISTRICT 1669 2. CHERRY CREEK AND TRIBUTARIES, COLORADO Location.-Cherry Creek is a small tributary of the South Platte River. It has its source 11 miles south and east of Monument, Colo., in El Paso County, flows generally north, and joins the South Platte River within the city limits of Denver. Existing project.-The project document plan of improvement provided for the construction of a reservoir on Cherry Creek at the site of the old Castlewood Dam and a second reservoir on the lower river at the Cherry Creek Reservoir site, No. 1, 6.75 miles above the city limits of Denver, to protect that city against any flood reasonably to be expected and to eliminate practically all further damages from Cherry Creek floods in the agricultural valley above Denver. Present plans provide for construction of the Cherry Creek Reservoir at an alternate site at the location of the former Kenwood Dam at river mile 11.4 on Cherry Creek, and for deferment of construction of the Castlewood Dam until such time as justified by the multiple-purpose requirements of the up- per Cherry Creek Basin. The Cherry Creek Dam and Reservoir at the Kenwood site provides reservoir storage capacity of 95,000 acre-feet below the spillway canal invert and surcharge storage of 136,400 acre-feet above this elevation. Initial plan of operation is for flood control only. The plan of operation in the ultimate development for multiple-purpose use includes 10,000 acre-feet of dead storage for silting, 85,000 acre-feet for conservation and other uses, and surcharge storage capacity for flood-control pur- poses. The rolled-earth dam is 14,300 feet long, with a maximum height of 140 feet. The overflow spillway discharges through the right abutment into Tollgate Creek. The outlet works is designed to fully comply with local conditions. The estimated cost of the initial project for flood control only, revised in 1950, is $15,200,000. The project will be operated as a part of the comprehensive plan for the Missouri River Basin. The comprehensive plan for the improvement of Cherry Creek and tributaries, Colorado, for flood control and other purposes in accordance with the recommendations of the Chief of Engineers was authorized by flood control acts as follows: Acts Work authorized Documents Aug. 18, 1941 The initiation and partial accomplishment of the H.

Operations and results during fiscal year.-Placing of embank- ment for the dam was completed, as was the contract to furnish and deliver trash racks, stop logs, stop log lifting device and rak- ing platform crane. Also completed with stabilization of outlet 1670 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 escape channel and construction of water-stage recorder, fencing downstream toe of dam, and clearing and disposing of trees and other debris in the reservoir basin. Contracts awarded during the year included those for construction of a service bridge, seeding spillway slopes and spoil banks, and construction of road across dam, access roads and parking areas. Acquisition of reservoir area land and flowage rights was completed except for final settle- ment in condemnation of certain tracts. The total cost during the fiscal year was $3,397,105.69, all for new work; expenditures were $3,720,011.61. Condition at end of fiscal year.-The existing project is about 90 percent complete. The impervious earth cut-off, the outlet works together with appurtenances, the spillway canal, and placing of embankment are completed. Work remaining to be completed con- sists of miscellaneous items of work such as care taker's quarters, potable water supply, experimental seeding of excavated sur- faces, removal of existing utilities and construction of gateway. The total cost to June 30, 1950 was $14,125,354.66, all for new work; expenditures were $14,165,199.34. Proposed operations.-The unexpended balance of $658,779.90, plus accounts receivable of $37,068.79, in addition to an antici- pated allotment of $200,000 during fiscal year 1951. a total of $895,848.69, will be applied during the fiscal year ending June 30. 1951, as follows: Accounts payable to June 30, 1950 ............................ $34,389.32 New work: Preliminary work by hired labor (July 1, 1950, to June 30, 1951) ........................................... 60,200.00 Construction of service bridge (July 1, 1950 to Sept. 10, 1950) ............................................... 46,750.00 Seeding spillway slopes and spoil banks (July 1, 1950 to Sept. 1, 1950) ....................................... 10,300.00 Construction of highway across dam, access road and park- ing areas (July 1, 1950 to Oct. 15. 1950) .............. 164,250.00 Acquisition of reservoir areas (reserve for contingencies and additional court awards) (July 1, 1950 to June 30, 1951) .. .......................................... 112,500.00 Construction of caretaker's quarters and service building, potable water supply and utilities, public comfort fa- cilities, landscaping, removal of existing utilities from reservoir area, project markers, signs; and identification tablets and miscellaneous items of work (July 1, 1950 to Dec. 31, 1950) ................................... 124,600.00 Experimental seeding of excavated and spoil bank areas (July 1, 1950 to June 30, 1951) ..................... 85,000.00 Future work and contingencies .......................... 257,859.37 Total for all work ................................. 895,848.69 It is anticipated that the initial phase of construction will be completed early in fiscal year 1951 with funds already appropriat- ed.

MORRISON, BEAR CREEK, COLO. Location.-This project is located on Bear Creek at Morrison, Colo., about 10 miles southwest of Denver. Existing project.--The project was authorized by the Flood Control Act approved December 22, 1944. (See H'. D. 356, 78th Cong., 1st session., which contains the latest published map.) The general plan of improvement provides for the protection from flood damage of the residents, tourists, and property of the town of Morrison, Colorado. The plan of improvement in and immedi- ately adjacent to Morrison provides for clearing, widening, and channel rectification of Bear Creek and construction of a concrete lined channel located so as to obtain optimum entrance and con- fluence conditions, for Mount Vernon Creek tributary. The esti- mated Federal cost for construction, revised in 1950, is $559,000, and the estimated local cost, revised in 1950, is $6,000 for lands and damages. Local cooperation.-See page 8 for requirements. As a part of the requirements for local cooperation as provided by law, local interests are required to establish and enforce flood channel limits and regulations satisfactory to the Secretary of the Army.

Open-channel work, Ohio River ................................ 1685 NOTE.-Tributary navigation projects and all flood-control projects in the Ohio River Basin are contained in the reports of the districts included in the Ohio River Division. 1. 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. 1677 1678 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 canalization 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 dam and in addition an auxiliary lock 56 by 360 feet at Emsworth, Dashields, Montgomery, and dam 41 and 110 by 360 feet at Galli- polis. 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 dams are also provided with one or more regu- lating weirs. At dam 41 a canal (Louisville and Portland) extends along the left bank for a distance of 2 miles, with the locks at the lower end. Operation and care of the locks and dams were included in the project July 1, 1935, under the provisions of the Permanent Ap- propriations Repeal Act approved June 26, 1934. The estimate of cost of new work revised in 1950, including expenditures on previous projects prior to adoption of the 9-foot project in 1910, but exclusive of the Gallipolis locks and dam reported under the Kanawha River project, is $321,473,000, in- cluding cost of old structures which have been replaced. The estimate of annual cost of operations and care of locks and dams, made in 1949, is $7,013,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents June 25, 1910 Construction of 54 locks with movable dams, widen- H. Doc. 492, 60th Cong., 1st sess. ing of the Louisville and Portland Canal to 170 feet, and a new lock at the lower end. The act also granted discretionary authority to the Secretary of War to make such modifications in the project as appeared advisable. July 18, 1918 Elimination of locks and dams in the lower river H. Doc. 1695, 64th Cong., 2d sess. where the project depth of 9 feet could be satis- factorily maintained by open channel work. Secre- tary of War authorized to substitute fixed dams for movable dams wherever, in his opinion, they may be advisable. Under the authority granted in the River and Harbor Act of June 25, 1910, the Louisville and Portland Canal has been widened to 200 feet; locks and dams 40 and 42 have been eliminated; locks and dams 1 and 2 replaced by the Emsworth locks and dam; lock RIVERS AND HARBORS-OHIO RIVER LOCKS AND DAMS 1679 and dam 3 replaced by the Dashields locks and dam; and locks and dams 4, 5, and 6 replaced by the Montgomery locks and dam. Locks and dams 24, 25, and 26 were replaced by Gallipolis locks and dam which was authorized by the act of August 30, 1935, and con- structed under the project for improving lower Kanawha River.

At certain unstable bars the project depth is maintained by dredging, supplemented by contraction works. (See project "Open Channel Work, Ohio River," p. 1685). Table A under "Existing project" shows cost and year of completion of locks and dams now in operation. The following originally contemplated work remains to be completed: Construction of an access road to Dashields Locks; raising crest of dam 14; construction of bear traps at dam 21 and construction of additional bear traps at dams 18, 22, 23, 27, 30, 39 and 43. In addition to completion of the above work, the following 'betterments are proposed to certain existing struc- tures in order to provide adequate facilities for present day navi- gation: Construction of guard wall and guide wall extensions at locks and dams 35, 41, 44, 45, 46, 48, 49, 50, 51 and 52. Also part of the works of the existing project do not provide adequate facili- ties for present day navigation due to obsolescence of the struc- tures. Since repair and modernization of these facilities would be extremely costly, replacement and reconstruction is contemplated as follows: Construction of locks and dam in the vicinity of Strat- tonville, Ohio (New Cumberland locks and dam) to replace locks and dams 7, 8 and 9; construction of locks and dam in the vicinity of Greenup, Ky., to replace locks and dams 27, 28, 29 and 30; con- struction of locks and dam in the vicinity of Fernbank, Ohio, to replace locks and dams 34, 35, 36 and 37 and the reconstruction of locks and dam 41.

OPEN-CHANNEL WORK, OHIO RIVER Open-channel work on the Ohio River is in charge of the district engineer in whose district the work is located. For information as to the limits of the three districts on the Ohio River, as well as the district engineers in charge thereof, see page 1677. 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 Mis- sissippi River Commission. Existing project.-Priorto 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, the 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 dams, 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. In order to properly facilitate the movement of the present-day barge tows, it has been found necessary to provide channel widths, varying according to 1686 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 the difficulty of running the channel, of from 500 to 750 feet. 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 pro- tection 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, revised in 1950, is $21,546,000, 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 estimate of annual cost of maintenance, made in 1949, is $1,480,000. The existing project was authorized by the following river and harbor acts: 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 provided 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, H. Doc. 187, 67th Cong., 2d sess. with funds allotted from the appropriations for general open-channel work. July 3, 1930 Reforestation of the sloughs on Kentucky Peninsula 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 purpose of this improvement (H. Doc. 409, 69th Cong., 1st sess.). However, since no serious overbank erosion has occurred since the RIVERS AND HARBORS-OHIO RIVER OPEN CHANNEL WORK 1687 bank revetment in 1933-34, reforestation is not considered justi- fiable at this time and no local cooperation is required. Terminal facilities.-See page 1682. Operations and results during fiscal year.-Dredging, where required to provide an adequate and dependable channel of proj- ect depth at minimum pool conditions, was executed. The dikes and revetments were maintained and the routine work of main- taining navigation aids, removing snags, making channel studies and hydrographic surveys was performed as required.

Location.-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- 1691 1692 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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.-This provides for the con- struction 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 extreme low water from the mouth to lock and dam 1, Nashville, Tenn. (188.4 miles above the mouth), the first lock constructed under the project for the section of the river above Nashville. The project also provides for surmounting dams A to F with movable crests. The construction of lock and dam 52, Ohio River, has created a pool of more than 6-foot depth in the Cumberland River as far as lock and dam F.

RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 1693 The extreme fluctuation in the stage of the river varies from about 32 to 64 feet at different localities. Fluctuations below ex- treme high water are so variable that it is impracticable to fix the stage commonly referred to on other streams as ordinary high water. The estimate of cost for new work for the section below Nash- ville, revised in 1947, is $5,035,802, excluding amounts expended on previous projects. The River and Harbor Act approved July 24, 1946 (Public Law 525, 79th Cong., 2d sess.), authorized the further improvement of the Cumberland River between the mouth and Nashville for 9-foot navigation by the construction of moderate height dams at Kut- tawa (Eureka), Dover, and Cheatham sites, currently planned at miles 32.2, 100.1, and 148.7, respectively, above the mouth. The cost revised in 1950 of canalization with locks 110 feet wide and 800 feet long, is estimated as $43,500,000. The prosecution of the authorized modification of the existing project on the Cumberland River will eliminate locks A to F, inclusive, below Nashville, and lock 1, above Nashville. (See H. Doc. 761, 79th Cong., 2d sess.) The existing project for the section below Nashville was author- ized 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.-This provides 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 naviga- tion from Waitsboro Shoals to Burnside (3 miles). The project also provides for the periodic removal of snags and similar ob- structions from Nashville (lock and dam 1) to Burnside (327.6 miles). The project as modified by River and Harbor Act of July 3, 1930, further provided for raising dam 1 by 3 feet (Rivers and Harbors Committee Doc. 26, 70th Cong., 2'd sess.).

The extreme fluctuation in the stage of the river varies from about 42 to 71 feet at different localities. Fluctuations below ex- treme high water are so variable that it is impracticable to fix the stage commonly referred to on other streams as ordinary high water. The estimated cost for new work for the section above Nashville, revised in 1947, is $14,600,000 including $25,000 for raising dam 1 in accordance with the River and Harbor Act approved July 3, 1930, and excluding the costs of projected locks and dams 16 and 17 which will be eliminated by the Wolf Creek reservoir. The actual cost of locks and dams 1 to 8 and 21 (already completed), and the, estimated cost each of locks and dams 9 to 15 are given in the table above. The River and Harbor Act approved July 24, 1946 (Public Law 525, 79th Cong., 2'd sess.) also authorized, in addition to the fur- ther improvement for navigation between the mouth and Nash- ville, the construction of Old Hickory, Carthage, and Celina Dams above Nashville for navigation and power. The cost, revised in 1950, (including a lock at Old Hickory) is estimated as $118,240,- 000.

The estimated annual cost for maintenance of both sections of the river, revised in 1949, is $850,000, of which $775,000 is for operating and care of locks and dams. Local cooperation.-Below Nashville: None required. Above Nashville: Fully complied. with. Terminal facilities.-At Nashville, Tenn., there is a five-story terminal building 300 feet long and 140 feet wide, built of rein- forced concrete, having large, and convenient loading platforms, electric elevator and crane, with railroad connections, municipally owned and open for public use. At Clarksville, Tenn., there is a privately owned warehouse with inclined tramway. Privately owned terminals for the transfer of petroleum products have been constructed at Dover, Clarksville, and Nashville, Tenn. There are also privately owned terminals located at Barret rock quarries, Kentucky, used for the transfer of riprap rock; near Vicksburg, Pinckneyville, and Dycusburg, Ky., for the transfer of fluorspar; at Clarksville, Tenn., for the transfer of sand and gravel; and at Nashville, Tenn., for the transfer of sand and gravel and forest products. 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.- (a) Below Nash- ville: New work consisted of the continuation of planning and the initiation of construction under the authorized modification of the existing project for nine-foot navigation. Construction operations consisted principally of placement of cofferdam cells, lock foundation excavation, and roadway grading under a continuing contract awarded during the later part of the year for construction of the Cheatham lock, including operations building and access roads. Approximate quantities of the major, items of work accomplished were: Common excavation (lock), 202,330 cubic yards; dumped riprap, 100 cubic yards; roadway RIVERS AND HARBORS--NASHVILLE, TENN., DISTRICT 1697 excavation, 39,130 cubic yards; and corrugated metal pipe in- stalled, 770 lineal feet. The following items of lock operating equipment, to be furnished by the Government, were contracted: Lock (miter) gates, valves, and operating machinery; culvert bulkheads; and floating mooring bitts. Hired labor operations included the preparation of contract plans and specifications for the Cheatham lock, lock operating equipment, operations building, and access roads; the initiation of activities for acquisition of lands required for the lock and dam site, disposal area, temporary work areas, and access roads; and the continuation of preliminary engineering and design studies on other phases of the project. In addition, work incident to the development of detailed project plans for Dover lock and dam was completed. The costs for new work were $462,886.62. Maintenance by Government plant and hired labor included navigation inspection, removing 1,485 cubic yards of mud and 2,222 snags from the channel, and dredging 49,142 cubic yards of sand and gravel at the following sites: Little Horse Ford (mile 33.8), 15,262 cubic yards; Upper Kuttawa Bar (mile 40.8), 6,205 cubic yards; Shelley Island (mile 54), 5,750 cubic yards; Devils Elbow (mile 64), 12,250 cubic yards; and lower approach to Lock A (mile 150.2), 9,675 cubic yards. The cost of mainte- nance was $72,252.63. (b) Above Nashville: Maintenance by Government plant and hired labor consisted of navigation inspection, removing 95 cubic yards of mud and 121 snags from the channel, dredging 7,200 cubic yards of sand, gravel, and silt at Jefferson Street Bridge (Nashville harbor, mile 190), and dredging 12,295 cubic yards of sand and gravel at the following sites: Nashville Island (mile 193.8), 5,380 cubic yards; and Goose Creek Bar (mile 280), 6,915 cubic.yards. The cost of maintenance was $20,931.44. (c) Operating and care of locks and dams: Locks A-F and 1-8, inclusive, were operated as required and the structures and appurtenances maintained in serviceable condition. Filling valves at locks 1, 2, 6, 8, and A, and the mooring cable above lock E were repaired. Repairs to wickets at lock A and the correction of soil erosion damage at lock 6 were initiated. In connection with conversion of locks A, C, D, E, and F to power operation, com- pressor houses were constructed at locks D, E, and F, and work incident to mechanization of the valves was continued. The latter item was not completed owing to non-arrival of valve operating machinery. Other operations included dredging of lock pits at locks A, B, D, E, F, 2, 3, 4, 5, 7, and 8; construction of a lower guard wall and dredging of lower channel approach at lock F; and installation of the following items: Mooring cables below locks A, B, C, D, E, and F; horn and light signal system and elec- tric navigation lights at lock 1; electrical grounding nets at all locks; a gate anchor at lock C; metal culverts in access road to lock E; and mitering devices on lock gates at locks A, B, C, D, E, and F. The cost of operating and care was $699,871.82. 1698 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The total costs during the year were $1,255,942.51, of which $462,886.62 was for new work, $93,184.07 for maintenance, and $699,871.82 for operating and care. The expenditures were $1,- 203,845.96. Condition at end of fiscal year.-(a) Below Nashville: All locks and dams under the existing 6-foot navigation project for this section of the river have been completed, affording full proj- ect depth between the mouth and Nashville throughout the entire year. The initiation of work on lock and dam A in June 1895 marked the commencement of construction under the project. The dates on which the individual locks and dams were completed and placed in operation are given in the tables under paragraph "Existing project." New work under the authorized modification of the existing project for 9-foot navigation, as a whole, was approximately 1 percent complete. Preliminary work was about 40 percent com- plete. Construction under the modified project was commenced in April 1950 when operations were initiated under a continuing contract for construction of the Cheatham lock; the contract being approximately 3 percent complete at the close of the year. Work under four contracts for lock operating equipment to be furnished by the Government, awarded near the end of the year, had not been initiated. Detailed inventory appraisals and investi- gations, in connection with the acquisition of lands required for the lock and dam site, access roads, and construction areas, have been completed on 12 of the 14 tracts involved. Acquisition was completed on 90 acres in fee simple and 70 acres in easement. The total costs for this section to June 30, 1950, were $6,- 125,436.06, including $685,000 from Public Works funds. Of this amount, $5,634,984.80 was for new work, and $490,451.26 for maintenance. * (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 completed structures were placed in operation are given in the tables under paragraph "Existing project". Projected locks and dams 16 and 17 have been eliminated and lock and dam 21 will be inundated by Wolf Creek Reservoir (described on p. 1714) now under con- struction. Operation of lock 21 was discontinued on May 4, 1947; custodial services only being maintained until May 31, 1949, at which time the structure was abandoned. Construction under the modified project, which precludes con- struction of the previously authorized locks and dams 9 to 15, inclusive, and will replace existing locks and dams 2 to 8, inclusive, has not been commenced. The existing locks and dams provide, at extreme low water, a navigable channel 6 feet deep from Nashville (lock and dam 1, 188.4 miles above the mouth) to Niagara Shoals, a distance of 143 miles. In the shallowest part of the uncanalized reach between RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 1699 the head of pool, lock and dam 8, and Wolf Creek dam, construc- tion of which has advanced to the point where the river is blocked at mile 460.9 above the mouth, the depth at extreme low water is about 0.5 foot. In this section, 3-foot navigation is practically certain from February 1 to May 1, and usually possible from January 1 to June 1. Four-foot navigation is usually possible from February 1 to May 1, but no period can be fixed during which it is reasonably certain. Navigation of vessels drawing over 4 feet is uncertain at all times. When the Celina gage reads 1 foot, 16-inch navigation is practicable, and for each additional foot of reading on this gage the navigable depth is increased 0.8 foot. The expenditures for maintenance have kept the channel above Nash- ville fairly free from snags and surface obstructions. The total costs for this section to June 30, 1950, were $4,090,- 823.75, of which $3,760,599.12 was for new work and $330,224.63 for maintenance. (c) Operating and care of locks and dams: All locks and dams except 21 were in operation, the structures and appurtenances hav- ing been maintained in good condition. The cost of operating and care since June 30, 1935, with funds from the appropriation "Maintenance and improvement of existing river and harbor works," was $5,472,267.00. The total costs under the existing project for the entire stream were $15,688,526.81, of which $9,395,583.92, including $685,000 from Public Works funds, was for new work, $820,675.89 for maintenance, and $5,472,267.00 for operating and care. The total expenditures were $15,583,846.76. In addition, the sum of $3,- 2'66,705.82 was expended between July 1, 1905, and June 30, 1935, on the operation and care of the works of improvement under the provisions of the permanent indefinite appropriation. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950, plus an anticipated appropriation of $2,983,159.00 for the fiscal year 1951, will be applied as follows: Accounts payable June 30, 1950 .......................... $93,138.59 New work: Cheatham lock and dam (below Nashville): Continue preliminary studies and preparation of plans and specifi- cations for dam (hired labor) (July 1, 1950 to June 30, 1951) ........ $114,191.85 Continue construction of lock (con- tract) (July 1, 1950 to June 30, 1951) ........................... 2,856,000.00 Continue land acquisition (hired labor) (July 1, 1950 to June 30, 1951) .... 40,000.00 Old Hickory lock and dam (above Nash- ville) : Detailed planning and preparation of construction plans and specifications (hired labor) (July 1, 1950 to June 30, 1951) ............... ................ 450,000.00 Total, new work ................................ 3,460,191.85 Maintenance (hired labor) (July 1, 1950 to June 30, 1951) : Dredging and snagging where required to maintain navigable channels (operation of derrick boat, Tishomingo, and atten- 1700 REPORT OF CHIEF OF ENGINEERS, U.

TENNESSEE RIVER, TENN., ALA., AND KY. Location.-The Tennessee River is formed by the junction of the French Broad and the Holston Rivers in eastern Tennessee, 4.4 miles above the Gay Street Bridge at Knoxville, flows southwest into northern Alabama, thence in a generally westerly course across north Alabama, to the northeast boundary of Mississippi, thence nearly due north across Tennessee and Kentucky, entering the Ohio River at Paducah, 652.1 miles from the junction of the French Broad and Holston Rivers. (See U. S. Geological Survey base map of the Tennessee River Basin.) Previous projects.- (a) Above Chattanooga.--Adopted by the River and Harbor Acts of August 30, 1852, June 10, 1872, August 18, 1894, and July 25, 1912. (b) Chattanoogato Riverton.-Adopted by the River and Har- bor Acts of August 30, 1852, July 25, 1868, March 3, 1871, Septem- ber 19, 1890; acts of April 26, 1904, and January 7, 1905; and River and Harbor Acts of March 2, 1907, June 25, 1910, July 25, 1912, July 27, 1916, and March 3, 1925. (c) Below Riverton.-Adopted by the River and Harbor Acts of July 25, 1868, September 19, 1890, August 18, 1894, March 3, 1899, and July 25, 1912. For further details see pages 1902 to 1906 Annual Report for 1915, pages 1190-1194, 1196-1216, and 1220-1222, Annual Report for 1929, and page 1216, Annual Report for 1938. The costs and expenditures for permanent work were $15,123,218.73. Existing project.-The River and Harbor Act of July 3, 1930 (Public No. 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; provided, 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 muncipalities; and provided further, that in case high dams are built before the 1702 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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, Seventy-first Congress, second session, ex- clusive 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. 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 total estimated cost of new work completed and proposed for construction by the Corps of Engineers is $2,436,235, made in 1947. The estimated annual cost of operating and care of the 10 locks, and dam 1 (including the locks constructed by .the Tennes- see Valley Authority and operated by the Corps of Engineers) is $765,000, made in 1949. The estimate of annual cost of channel maintenance, made in 1949, is $35,000. 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 provides for obtain- ing the authorized 9-foot project by the construction of high dams and locks and utilization of certain locks and dams previously con- structed under the jurisdiction of the Corps of Engineers.

The division of responsibility regarding the project is outlined in memorandum of agreement dated July 11, 1946, between the Tennessee Valley Authority and the Corps of Engineers. Local cooperation.-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 proj- ected 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 unim- proved landings. Government owned facilities for the transfer of coal are located at Hales Bar Dam, Tenn. and Huntsville Arsenal, Ala. Near Johnsonville, Tenn., there is a privately owned railroad siding. Railroad inclines and sidings are available at Sheffield, Decatur, Hobbs Island, Guntersville and Bridgeport, Ala., and Chattanooga, Tenn. Privately owned terminals have been con- structed for the transfer of certain commodities as follows: Auto- mobiles and miscellaneous merchandise at Guntersville, Ala.; coal at South Pittsburg and Chattanooga, Tenn.; grain at Decatur and Guntersville, Ala., and Chattanooga, Tenn.; petroleum products at Sheffield, Decatur and Guntersville, Ala., and Perryville, Chatta- RIVERS AND HARBORS-NASHVILLE, TENN., DISTRICT 1705 nooga, and Knoxville, Tenn. In addition to the foregoing there are many unimproved private landings along the river. The facili- ties are considered adequate for existing commerce. Operations and results during fiscal year.-No new work was accomplished. Maintenance by Government plant and hired labor consisted of removing 1,718 snags from safety harbors and chan- nels in the Fort Loudoun, Watts Bar, Chickamauga, Hales Bar, Guntersville, Pickwick, and Kentucky pools; dredging 6,000 cubic yards of sand, gravel, and silt at bar below Kentucky lock (mile 21.4) and 598 cubic yards at Second Creek Bar (Knoxville, Tenn., mile 647.2) ; condition surveys; and inspection of navigation chan- nel. The cost of maintenance was $42,942.76. Operating and care of locks and dams: All locks were operated as required, and lock appurtenances and stand-by plant were maintained. The upper and lower lock gates at Hales Bar lock and the lower lock gates at Wheeler lock were painted above water. Spare electric motors were procurred for the gate and valve operating machinery at Kentucky, Wheeler, Guntersville, Chickamauga, Watts Bar, and Fort Loudoun locks. Repairs were made to a leak in a valve pit at Watts Bar lock and to leaks in the inspection tunnel at Guntersville lock. General repairs to dwellings at Hales Bar lock were initiated. Other operations in- cluded raising and inspection of the emergency dam, and revision of floating mooring bitts, at Pickwick lock; construction of control shelters for Wilson, Wheeler, and Guntersville locks; drilling a culvert vent hole in the lock wall at Wilson lock; overhauling gate and valve operating machinery at Guntersville and Chickamauga locks; replacing horizontal seals of the valve bulkhead recesses at Watts Bar lock; adjusting valve bulkhead slot fillers at Fort Lou- doun lock; baking and revarnishing gate and valve motors at Watts Bar and Fort Loudoun locks; weatherstripping of dwellings at Wheeler lock; and installation of the following items: Gate anchors at Kentucky, Wheeler, and Chickamauga locks; sector arms and a stand-by hydraulic oil pump at lock 1; electric motor and equipment for operation of the bascule bridge, electric traffic gates, and an endless cable towing unit at Wilson lock; new pintles on upper lock gates at Wheeler lock; and heating plants in dwell- ings at Hales Bar lock. The installation of a new electric switch- board at lock 1 was initiated, but was later suspended owing to delayed delivery of equipment. The rewiring of the lock lighting system at Wilson lock was essentially completed. An examination made in connection with the repair of underwater cables of the floating guard wall at Kentucky lock indicated the necessity of new cables, and further work was deferred pending procurement of such. The cost of operating and care was $701,443.93. The total costs and expenditures during the fiscal year were as follows: 939127-51-vol. 2--18 1706 REPORT OF CHIEF OF ENGINEERS, U. S.

Construction under the project was commenced in Jan- uary 1933, when work was initiated on Wheeler lock. With the opening of Kentucky lock for permanent operation in September 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 remaining 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. The completed locks were operated and maintained under the permanent indefinite appropriation to the end of 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, in addition to the following: Pickwick 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.

Location.-This project is located at Cumberland, Ky., on the Poor Fork of the Cumberland River approximately 23 miles above its confluence with the Clover Fork at Harlan, Ky. Existing project.-The plan of improvement provides for par- tial flood protection at Cumberland, Ky., by improving the carry- ing capacity of the river through the heart of the city, affording an average reduction of 0.8 of a foot in stages of all known floods. The work consists of the removal of deposits of boulders, gravel, and sand and otherwise enlarging and realigning the existing channel, beginning at a point approximately 200 feet upstream from the United States Highway No. 119 bridge and extending 6,000 feet downstream to a point about 2,100 feet below the Billips Avenue Bridge, involving a total excavation of 44,000 cubic yards of material. The estimated cost of new work, revised in 1950, is $70.000 for construction (Federal) and $200 for lands and damages (non- Federal). The project was authorized by the Flood Control Act approved May 17, 1950. Local cooperation.-See page 8 for requirements. The pro- posed plan of partial protection and the requirements of coopera- tion were explained at a meeting with local interests on Decem- FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 1711 ber 22, 1947, at which time the mayor of Cumberland expressed willingness of the city to meet the necessary requirements if the project were authorized. Operations and results during fiscal year.-None. Condition at end of fiscal year.-Funds for prosecution of work on the improvement have not been made available. Proposed operations.-No operations are contemplated during the fiscal years 1951 and 1952. 7. 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 Bennetts Fork at the western edge of the town and ending at Yellow Creek near the Keystone Tanning & Glue Co. 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 utilized in the levee system. Besides construction of the diversion channel, there was other incidental work, which included the in- stallation of culverts and the relocation and rebuilding of road- ways and bridges. The project diverts from the business district and from a large part of the residential 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 estimated cost of new work, revised in 1947, is $817,830. The estimate of annual cost for maintenance is $5,800, made in 1949. 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 $1,947.50. The expenditures were $4,535.09, all from regular funds. 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, initiated 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, 1950, were $848,510.24, of which $817,829.98, including $38,876.31 from Emergency Relief Funds, was for new work and $30,680.26 for maintenance. The total expenditures were $848,502.26, including $38,876.31 from Emer- gency Relief funds. 1712 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Proposed operations.-The balance unexpended on June 30, 1950, plus $2,000 appropriated for the fiscal year 1950, will be applied as follows: Accounts payable, June 30, 1950 ............................... $3.98 Maintenance (July 1, 1950 to June 30, 1951) (hired labor) : Maintenance of levees, canal, and appurtenant works ........ 5,123.74 Stream gaging ........................................... 900.00 Total ................................................. 6,027.72 The additional sum of $8,000 can be profitably expended for maintenance scheduled during the fiscal year 1952.

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 provides for the construction of a system of levees and concrete flood walls for the protection of Pineville and its residential suburb, Wallsend, con- sisting of the following features: About 3,500 feet of earth levees and 3,600 feet of concrete walls around Pineville, beginning at a connection with United States Highway No. 25 E, approximately 700 feet southwest of the Tennessee Avenue bridge, and extending in a northeasterly, easterly, then southerly direction upstream along the left bank of the Cumberland River to rejoin the highway at a point 250 feet south of the intersection of Park Avenue and Maple Street near the upstream limit of the city; and about 3,500 feet of earth levee encompassing Wallsend on the right bank of the river, beginning and terminating within a distance of 1500 feet, in the embankment of the Louisville & Nashville Railroad which runs along the northern edge of the community. Incidental con- struction includes one pumping station each in Pineville proper and Wallsend, with appurtenant outlet works and intercepting sewers, for disposal of interior drainage; and necessary bridge and street modifications. The proposed works will afford protec- tion for the city of Pineville and suburb Wallsend, against floods of 1946 magnitude (maximum of record) with a 3-foot freeboard. The project was authorized by the Flood Control Act approved June 22, 1936. The estimated Federal cost of new work, revised FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 1713 in 1950, is $1,292,000; the estimated non-Federal cost is $640,000. Local cooperation.-See page 8 for requirements. Subsequent to passage of the authorizing act, local interests expressed in- ability to fulfill the requirements. Following the flood of January 1946, however, interest in the project was renewed, and informal assurances were furnished at a public hearing on April 27, 1946, and at a further meeting on December 22, 1947, relative to flood control in the upper Cumberland River basin, that the require- ments of local cooperation would be fully complied with. In com- pliance, a bond issue has been voted by the city to finance its share of the cost of the project. Operations and results during fiscal year.-None. Condition at end of fiscal year.-Prosecutionof the project has been held in abeyance pending fulfillment of local cooperation. The project was restudied in connection with an investigation carried out during fiscal year 1948 in interest of flood control in the upper Cumberland River basin, printed as House Document 345, Eight-first Congress, first session, and local interests ex- pressed willingness to meet the requirements of local participa- tion if work on the improvement, as recommended therein, is initiated. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952. 9. BARBOURVILLE, KY. Location.-The project is located at Barbourville in Knox County, Ky., on the right bank of the Cumberland River at mile 635.2. Existing project.--The plan of improvement provides for the protection of Barbourville, Ky., by construction of a system of levees with an average height of 15 feet beginning at the Louis- ville and Nashville Railroad tracks northeast of the town and ex- tending westerly and southwesterly about 5,800 feet, thence south- easterly along the left bank of Richland Creek for approximately 6,300 feet, thence along the right bank of the Cumberland River in a northeasterly and southeasterly direction for approximately 4,000 feet, including relatively short concrete wall sections adja- cent to the bridge spanning the river, thence easterly for about 900 feet terminating into the Louisville & Nashville Railroad em- bankment southeast of the town. The total length of the levees approximates 17,000 feet. Incidental construction includes five pumping stations with outlet works and intercepting ditches, for disposal of interior drainage, and five ramps at road and street crossings. The proposed works will afford protection 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, revised in 1950, is $1,840,000 for construction (Federal) and $230,000 for lands and damages (non-Federal). Local cooperation.-See page 8 for requirements. The plan of 1714 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 improvement and the requirements of cooperation were discussed at a meeting with local interests on May 18, 1948. The project was approved by the city council on May 21, 1948, and provisions were subsequently made to vote bonds for financing the city's share of the cost of the project. Operations and results during fiscal year.-None. Condition at end of fiscal year.-Funds for prosecution of work on the improvement have not been made available. Proposed operations.-No work is scheduled for the fiscal year 1951. The sum of $25,000 can be profitably expended for planning scheduled during the fiscal year 1952. 10. WOLF CREEK RESERVOIR, OHIO RIVER BASIN, KY. Location.--The site of the Wolf Creek Dam is on the Cumber- land River, 460.9 miles above its mouth. It is in Russell County, Ky., and is about 10 miles southwest of Jamestown, Ky., and 12 miles north of Albany, Ky. The Wolf Creek Reservoir will extend 101 miles up the main stream, 48 miles up the South Fork of Cum- berland River, and will lie within Russell, Clinton, Wayne, Pulaski, McCreary, Laurel, and Whitley Counties, Ky. Existing project.-The plan of improvement provides for the construction of a combination earth and concrete gravity-type dam, 5,736 feet long and 240 feet in height above its lowest foun- dation; and a hydroelectric power generating plant. The dam will consist 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 will contain 6 gate-controlled conduits and will be surmounted with 10 tainter crest gates to provide for regulating and discharg- ing flood flows. The powerhouse, a reinforced concrete structure of the conventional indoor type, will be located directly at the downstream base of the power intake section of the dam through which 6 penstocks will be constructed. The power installation will consist initially of six 45,000 kilowatt generating units. The proj- ect 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 compre- hensive plan of development for the Ohio and Mississippi Rivers. At maximum controlled pool level, top of spillway crest gates, the reservoir will cover an area of 63,530 acres and provide a storage capacity of 6,089,000 acre-feet, of which 2,094,000 is allocated for flood control and 2,142,000 for power drawdown, leaving a mini- mum pool of 1,853,000 acre-feet available at all times for public use and conservation purposes. The drainage area controlled will be 5,810 square miles or approximately one-third of the Cumber- land 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 FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 1715 July 24, 1946. The current (1950) estimated cost of the project, including the six-unit power installation, is $82,700,000. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work (con- tract) : Construction operations for completion of dam and appur- tenant works, and miscellaneous activities under supply contracts for materials and equipment furnished by the Government were continued. The principal items of works under the contract for construction of the dam were brought to the following percentages of completion: Common excavation, 89 percent; rock excavation, 99 percent; rolled fill, 88 percent; concrete placed, 93 percent; re- inforcing steel placed, 88 percent; and cofferdam, 83 percent. Work under contracts for furnishing 10 tainter gates and 10 units tainter gate operating machinery was completed; and the contract' for furnishing and delivering one 250-ton powerhouse crane was essentially completed. Additional items contracted in- cluded: Miscellaneous powerhouse accessory electrical equipment; one 10 ton gantry crane; one 5,000 pound capacity freight ele- vator; concrete aggregate for use in construction of powerhouse superstructure; and sale and removal of one railway bridge and four highway bridges being replaced with new bridges. The prog- ress of work under the various supply contracts at the end of the year was satisfactory. Work under a continuing contract for completion of the power plant was initiated in November 1949. Work accomplished con- sisted primarily of mobilization of forces and equipment, together with the following: Rock excavation, 15 cubic yards; concrete placed, 327 cubic yards; reinforcing steel placed, 2700 pounds; and initiation of work on installation of draft tube unwatering, sta- tion drainage, generator cooling water, treated water, raw water, sewage disposal, lubricating oil and transil oil systems. Operations under three contracts for clearing portions of the reservoir were completed, and work under two other contracts was continued. A total of approximately 22,840 acres was cleared dur- ing the year. Two contracts for removal of 110 cemeteries from the reservoir were also completed, the remains of approximately 2,450 bodies being relocated. Under an agreement entered into with the State of Kentucky for highway and highway bridge relocations made necessary by construction of the project, the State prosecuted work under 17 contracts, six of which were placed in force during the year. Work under six of the contracts was completed. The agreement pro- vides for reimbursement by the Government of its proportional part of the relocation costs. Under a similar agreement with the Southern Railway, work was carried on under three contracts awarded by that agency covering necessary railway and railway bridge relocations, all in the vicinity of Burnside, Kentucky. Work under two of these contracts was completed. Work under a con- tract for waterworks and street construction in connection with the relocation of the city of Burnside, Ky., was completed except for final tests of intake pumping equipment, which cannot be 1716 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 made until the reservoir level reaches the required minimum ele- vation. In addition to completion of the water plant, the following approximate quantities of major items of work were accom- plished: Clearing and grubbing 2.5 acres; excavation, unclassified 17,235 cubic yards; rock excavation, 840 cubic yards; reinforced concrete pipe placed, 210 lineal feet; 4- to 8-inch water pipe placed, 12,190 lineal feet; concrete sidewalk, 720 square yards; concrete curb and gutter, 1,610 lineal feet; traffic-bound stone placed, 5,270 tons; water-bound coarse aggregate 4,420 tons; water-bound screenings, 2,460 tons; mixed in place aggregate, 2,600 tons; and bituminous material, 53,090 gallons. As part of the Burnside water system, one 100,000-gallon water tank was furnished under a separate contract and its erection was completed. New work (hired labor) : Operations completed during the year included preparation and issuance of contract plans and specifica- tions for miscellaneous powerhouse accessory electrical equipment, one 10-ton gantry crane and one 5,000-pound capacity freight ele- vator; preparation and issuance of specifications for concrete ag- gregate required in construction of powerhouse superstructure; reconnaissance surveys, throughout the reservoir area, of possible requirements for relocation of county roads and utilities and for new facilities in isolated areas; and preparation of master plan for development of reservoir management and public use facilities. Land acquisition activities were continued, a total of 9,574 acres being acquired in fee simple and 361 acres in easement. Operations for removal and salvage of improvements from the reservoir area covered approximately 66,000 acres during the year. Agreements were entered into with the American Telephone & Telegraph Co. and the South Kentucky Rural Electric Cooperative Corp. for the relocation of affected telephone and power lines, respectively; and negotiations were continued with counties and other utility com- panies for relocation of roads, additional power and telephone lines and other utilities. Tentative agreements were reached in four instances involving utility relocations, and condemnation ac- tion was instituted with respect to roads in one county where the county refuses to fulfill an agreement made by the previous ad- ministration. Other operations included stream gaging; review and revision of contract plans and specifications for the power plant; checking of shop drawings pertaining to power plant construction; and the initiation of work under the reservoir management program, which involved the construction of five operational access roads, the initiation of reservoir patrol activities, and the cancellation of leases on all residential properties in Burnside, Ky., preparatory to clearing and salvage operations in that portion of the reservoir area. The costs for new work were $17,184,702.48. The expenditures were $17,271,698.29. Condition at end of fiscal year.--The project as a whole was 67 percent complete. Preliminary work was 82 percent complete. Construction of right- and left-bank access roads and the provi- sion of a temporary construction camp at the project site for FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 1717 Government inspection personnel were completed during early stages of the project. Work under the original contract for con- struction of the dam and appurtenant works was begun in August 1941, but was terminated in 1943 in the interest of the war effort, when about 8 percent complete. A new continuing contract for completion of the dam was awarded and work under that' con- tract, commenced in September 1946, was approximately 89 per- cent complete at the end of the fiscal year. Construction of the power plant, initiated during the year, was about 1 percent com- plete. Contracts for the following have been completed: Aerial photography of reservoir; access roads; power plant design; clear- ing line survey (lower and central portions of reservoir) ; slide gates; intake gates and hoisting equipment; draft tube pier nose castings; tainter gates; tainter gate anchorages; tainter gate fixed metal; tainter gate operating machinery; cement (under two original contracts) ; reservoir clearing (under three of five contracts awarded) ; cemetery removals (under three contracts) ; waterworks and street construction for relocation of Burnside, Ky.; furnishing and erection of one 100,000-gallon steel water tank, Burnside, Ky.; and appraisal reports on industrial properties in Burnside, Ky. The status of work on other items by contract was as follows: Furnishing cement (under two new contracts), 74 percent complete; reservoir clearing (under two remaining contracts), 93 percent; main unit turbines, governors and genera- tors, 20 percent; and miscellaneous power plant equipment, 63 per- cent. Work accomplished under agreement with and contracted for by the State of Kentucky for highway and highway bridge reloca- tions in the reservoir represented approximately 62 percent of the entire obligation of the Government under the agreement. Like- wise, work accomplished under agreement with and contracted for by the Southern Railway for railway and railway bridge reloca- tions in the reservoir represented approximately 94 percent of the entire Government obligation. Mapping of reservoir (731 square miles), by hired labor, has been completed. Salvage operations in the reservoir, by hired labor, were approximately 89 percent complete. Detailed inventory appraisals and investigation 's in connection with acquisition of lands within the reservoir have been completed on 2,319 of the 2,326 tracts involved. Approximately 98 percent of the necessary lands has been acquired, about 90,386 acres having been obtained in fee simple and 472 acres in road and flowage easements, of which 56 acres were donated. Total costs to June 30, 1950, were $55,240,885.28 for new work. The total expenditures were $53,208,902.69. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950, plus anticipated allotments of $22,- 000,000 for new work and $117,000 for maintenance during fiscal year 1951, will be applied as follows: Accounts payable June 30, 1950 ......................... $1,950,872.61 New work: Preliminary work: Stream gaging (July 1, 1950 to June 30, 1951) ....................... $4,300.00 1718 REPORT OF CHIEF OF ENGINEERS, U.

DALE HOLLOW RESERVOIR, OHIO RIVER BASIN, TENN. AND KY. Location.-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, Picket, Overton, and Fentress Counties, Tenn. Existing project.-The plan of improvement provides for con- struction of a concrete gravity-type dam, 1717 feet long and 185 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 abut- ments. Four gate-controlled conduits through the base of the spill- 1720 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 way section and six tainter crest gates 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 three penstocks were constructed. The power installation consists of two 18,000 kilowatt generating units with provisions for a third unit of like capacity to be placed at a future date. 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 com- prehensive 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 al- located for flood control and 496,000 for power drawdown, leav- ing a minimum pool of 857,000 acre-feet available at all times for public use and conservation purposes. The drainage area con- trolled is 935 square miles or 99 percent of the Obey River Basin. The project was selected for construction under the general au- thorization for the Ohio River Basin contained in the Flood Con- trol Act approved June 28, 1938 and the additional authorization contained in the River and Harbor Act approved July 24, 1946. The estimated cost of the project, including the three-unit power installation, revised in 1950, is $26,050,000. The estimate of an- nual cost for maintenance and operation of the project, revised in 1950, is $300,000. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work (con- tract): Minor deficiency corrections, escalation and final settle- ment under several supply contracts for materials and equipment furnished by the Government for use in the construction of the power plant (initial development) were continued. The preparation, by contract, of plans and specifications for five permanent residences and one comfort station at the dam site was completed. Construction thereof was commenced under a con- tinuing contract in May 1950. Operations included excavation for foundations, placement of concrete foundations and floors, erec- tion of block walls, and installation of plumbing in all five houses. Foundation work on the comfort station was initiated. New work (hired labor) : In connection with completion of land acquisition activities, some progress was made on completing ac- tion on outstanding cases in condemnation with the rendering of court awards on 19 of the 43 tracts involved. Preliminary work and construction for development of reservoir management and public use facilities were continued. Operations included completion of the project overlook, partial completion of public use facilities at the dam site and the establishment of one additional commercial dock site. Grading and landscaping of the permanent housing area at the dam site was also continued, and the installation of utilities for the area was commenced. Other operations consisted of work incident to preparation of power FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 1721 plant completion report and operation and maintenance manual. Maintenance (operating and care) : The dam was operated and the structure and its appurtenances were maintained as required. Stream gaging operations were continued. Operation of the power plant was continuous throughout the year, except for few periods of short duration for inspection and maintenance purposes. Under existing regulations, the total net energy generated, amounting to 160,814,800 kilowatt-hours, was made available through the De- partment of the Interior to the Tennessee Valley Authority for distribution. Regulation of the reservoir during the year required almost daily releases for the generation of power. Releases for power, exclusively, were made during the periods July 1, 1949 to January 29, 1950, February 3 to February 9, 1950, and February 23 to June 30, 1950, inclusive. Flood-control operation was necessary from January 30 to February 2, 1950, and from February 10 to February 22, 1950, with a maximum release of 14,200 cubic feet per second on February 16, 1950. The average pool elevation was 645.6 feet, which is 5.4 feet below the spillway crest level. Reser- voir storage varied from a minimum of 970,000 acre-feet in De- cember 1949, corresponding to a pool elevation of 636.0 feet, to a maximum of 1,547,000 acre-feet, corresponding to elevation 657.8, following a flood period during January and February 1950. Dur- ing the occurrence of two crests of that flood, the operation of the project resulted in crest reductions at Celina, Tenn., on.the Cumberland River of 2 and 1 feet, respectively. Operation of this project in conjunction with Center Hill Reservoir during the two flood peaks resulted in crest reductions on the Cumberland River of 11.9 and 8.1 feet at Carthage, Tenn., and 4.7 and 3.3 feet at Nashville, Tenn., respectively. Activities under the reservoir management program compris- ing shoreline sanitation, malaria control, conservation, land man- agement and disposal, and operation and maintenance of public use facilities were continued. The costs were $459,194.33, of which $238,373.20 was for new work and $220,821.13 for maintenance. The expenditures were $624,402.87. Condition at end of fiscal year.-The project as a whole was 98 percent complete. Preliminary work was 97 percent complete. Construction of the dam and its appurtenances, initiated in March 1942, was completed and the improvement placed in operation for flood control in October 1943. Relocated Tennessee Highway No. 42 bridge was completed in December 1945, and the power plant with two 18,000-kilowatt generating units (initial development) in commercial operation, was completed in April 1949. Work under the contract for construction of permanent housing and comfort station at the project site was about 36 percent complete. Work under all other contracts was complete except in a few in- stances involving escalation and final settlement which were in progress at the end of the year. Mapping of the reservoir (258 square miles) has been com- pleted, and the reservoir area cleared. A total of 20,203 acres of 939127--51-vol. 2---19 1722 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 land were cleared. A total of 2,293 graves were removed, by con- tract, from the reservoir area and relocated. Six highway bridges were also removed by contract from the reservoir. Acquisition of necessary lands for the reservoir has been completed, except for final processing of condemnation proceedings on a number of tracts acquired by declaration of taking. Of the 43 tracts on which final action is pending, court awards have not yet been rendered on 24 tracts. The reservoir area acquired includes 52,405 acres in fee simple, 89 acres of flowage easements and 2 acres of road ease- ment. The total costs to June 30, 1950, were $24,142,073.56, of which $23,609,767.34 was for new work and $532,306.22 for mainte- nance. The total expenditures were $24,058,139.42.

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. The Center Hill Reservoir will extend about 64 miles up the main stream and about 10 miles up Falling Water River, and will lie within De Kalb, Putnam, White, and Warren Counties, Tenn. Existing project.-The plan of improvement provides for con- struction of a combination earth and' concrete gravity-type dam, 2,160 feet long and 240 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 flood flows. In addition to the main dam structure, the project provided for con- struction 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 1724 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 powerhouse, a reinforced concrete structure of the conventional indoor type, will be located directly at the downstream base of the power intake section of the dam through which three penstocks were constructed. The power installation will consist initially 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 the water resources of the Cumberland River Basin, this plan in turn forming an integral part of the comprehensive plan of devel- opment for the Ohio and Mississippi Rivers. At maximum con- trolled 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 conservation 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 authoriza- tion 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 current (1950) estimated cost of the project, including the three-unit power installation, is $45,700,000. The estimate of annual cost for maintenance and operation of the project, made in 1950, is $345,- 000. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work (con- tract) : Work under the contract for construction of the dam, ap- purtenant works and access roads, as amended to include con- struction of the power plant, was continued. Construction of the dam proper was practically completed, and work on the power plant progressed on schedule. The principal items of work under the contract were brought to the following percentages of com- pletion: Common excavation, 88 percent; rock excavation, 99 per- cent; rolled fill, 99 percent; borrow excavation, 99 percent; con- crete placed, 99 percent; reinforcing steel placed, 95 percent; and powerhouse superstructure, 58 percent. Approximate quantities of the major items of work accomplished were as follows: Common excavation, 162,900 cubic yards; rock excavation, 8,390 cubic yards; rolled fill, 4,500 cubic yards; borrow excavation, 47,500 cubic yards; concrete placed, 21,415 cubic yards; and reinforcing steel placed, 1,694,800 pounds. Operations pertaining to power plant construction consisted of work on walls, floors and roof of the powerhouse including erection of structural steel roof trusses and miscellaneous activities in connection with installation of the following items: Main power units; station service unit; scroll case extensions; 250-ton crane; and various systems, such as tran- sil oil, station drainage, draft tube unwatering, ventilating, piezo- meter piping, generator water cooling, raw water and compressed air. Miscellaneous activities under supply contracts for materials and equipment furnished by the Government were also continued, FLOOD CONTROL-NASHVILLE, TENN., DISTRICT 1725 in accordance with delivery schedules. Operations under the con- tract for furnishing and delivering the house unit generator were completed. The removal of old Sligo Bridge, by contract, and a small quan- tity of work remaining at the beginning of the year under the contract for construction of Tennessee State Highway No. 56 bridge superstructure were also completed. In addition, work under a contract awarded during the year for drilling and grout- ing the left bank reservoir rim near the dam site was completed. Operations under the latter contract comprised approximately 34,900 lineal feet drilling and about 363,450 cubic feet grouting. Other awards during the year were for construction of permanent housing and for furnishing and delivering one 10-ton gantry crane. New work (hired labor) :Operations completed during the year consisted of the following: Preparation and issuance of plans and specifications for work items contracted during the year; removal and salvage of improvements within the reservoir area; and clear- ing of a small area of the reservoir not included under clearing contracts. The acquisition of lands required for the reservoir was continued, 404 acres being acquired in fee simple and 829 acres by transfer from the Tennessee Valley Authority. Under special authority, an additional 157 acres of land damaged by core drilling operations and one small area found to be below spillway elevation were acquired. Checking of shop drawings and revision of plans and specifications pertaining to power plant construction were also continued. Other operations consisted of work incident to prepara- tion of plans and specifications for permanent housing utilities, project overlook and comfort station. Maintenance (operating and care) : The dam was operated and the structure and appurtenances maintained as required. Stream gaging, and activities under the reservoir management program, comprising shoreline sanitation, malaria control, conservation, land management and disposal, and operation and maintenance of public use facilities were continued. Inasmuch as the power generating facilities have not been com- pleted, the project was operated primarily for flood control. Regulation of the reservoir necessitated periodic releases throughout the year, depending principally upon flood control re- quirements, with a maximum discharge of 41,400 cubic feet per second on February 11, 1950. The average pool elevation during the year was 615.4 feet, which is 32.6 feet below the spillway crest level. Reservoir storage varied from a minimum of 339,000 acre-feet in December 1949, corresponding to a pool elevation of 576.1 feet, to a maximum of 1,992,000 acre-feet at pool elevation 680.6, following a flood period during January and February 1950. During the occurrence of two crests of that flood, operation of this project in conjunction with Dale Hollow Reservoir resulted in crest reductions on the Cumberland River of 11.9 and 8.1 feet at Carthage, Tennessee, and 4.7 and 3.3 feet at Nashville, Tennessee, respectively. 1726 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The costs were $9,457,158.28, of which $9,390,556.42 was for new work and $66,601.86 for maintenance. The expenditures were $8,636,862.96.

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 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 RIVERS AND HARBORS-LOUISVILLE, KY., DISTRICT 1739 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 back- water from Ohio River when in flood is 60.3 feet, while extreme 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 ex- ceeds 40 feet. All flood heights are referred to upper-pool gages. The original estimate of cost, which contemplated the rehabilita- tion of the five State locks and dams and the extension of slack water to the three forks at Beattyville, was $1,074,402, revised later to $4,865,550 for its completion. The estimate of annual cost of maintenance of the Kentucky River, revised in 1949, is $75,000 for channel maintenance and $373,000 for operating and care of the locks and dams. 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, Forty-fifth Congress, third session (An- nual Report 1879, p. 1398). Operation and care of the locks and dams were included in the project July 1, 1935, under the provi- sions of the Permanent Appropriation Repeal Act, approved June 26, 1934. No project map of the river has been published. The following statement shows the characteristics of the several locks and dams in this project.

Operationsand results during fiscal year.-Maintenance: Work during the fiscal year consisted of the removal of shoals, snags, slides and overhanging trees as required to maintain an adequate channel in the pools of the dams. Maintenance (operating and care) : Work during the fiscal year consisted of the operation and maintenance of the 14 locks and dams. The costs were $39,808.87 for maintenance of channels and $246,841.24 for operating and care of locks and dams of which $195,841.24 was from regular funds and $51,000 from the appro- priation "Maintenance and operation of dams and other improve- ments of navigable waters" a total of $286,650.11. The expendi- tures were $267,427.16, of which $229,309.02 was from regular funds and $38,118.14 from the appropriation "Maintenance and operation of dams and other improvements of navigable waters." 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 con- struction 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 on the Kentucky River is in only fair condition. The condition of the concrete-capped, stone-filled timber crib dams at locks 1 to 8, inclusive, varies from fair to poor, and the limestone walls at locks 1 to 6, inclusive, and lock No. 8 are wearing awayr by erosion. The remaining locks and dams, 9 to 14, inclusive, are of concrete construction and the masonry is gener- ally in good condition. The controlling navigable depth in the sec- tion covered by the existing project was 6 feet at the end of the fiscal year. 'The costs to the end of the fiscal year were $4,176,749.05 for new work, $638,302.30 for maintenance, and $2,031,474.08 for operating and care of locks and dams, all from regular funds, and $51,000 for operating and care of locks and dams from the appropriation "Maintenance and operation of dams and other improvements on navigable waters", a total of $6,897,525.43. The expenditures were $6,878,072.33 of which $6,839,954.19 was from regular funds and $38,118.14 from the appropriation "Mainte- nance and operation of dams and other improvements of navigable waters". In addition, the sum of $6,405,371.78 was expended be- tween July 5, 1884 and June 30, 1937 on the operation and care of the works of improvement under the provisions of the permanent indefinite appropriation for such purposes. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950, plus an anticipated allotment of $339,853 during fiscal year 1951, will be applied as follows: RIVERS AND HARBORS-LOUISVILLE, KY., DISTRICT 1741 Accounts payable June 30, 1950 ............................ $23,111.43 Maintenance: Clearing channel in pools of dams (hired labor, July 1 to Oct. 15, 1950) ................................. 39,100.50 Maintenance: (Operating and care) -Hired labor, July 1, 1950, to June 30, 1951: Operation ................................. $109,000.00 Ordinary repairs .......................... 30,000.00 Improvement and reconstruction ............. 180,211.69 Total maintenance (operating and care) .............. 319,211.69 Total for all work ................................... 381,423.62 The additional sum of $160,000 can be profitably expended dur- ing the fiscal year 1952 for maintenance (operating and care) : exclusive of lock operation on the upper Kentucky scheduled to be discontinued.

GREEN, BARREN, AND NOLIN RIVERS, AND BEAR CREEK, KY. Location.-Green River rises in Casey County, Ky., flows in a northwesterly direction 370 miles, and empties into the Ohio River about 8 miles above Evansville. Ind. Barren River rises in Monroe County, Ky., flows in a north- westerly direction 130 miles, and empties into Green River one- half mile above lock 4 and 149.5 miles above the mouth of Green River. Bear Creek rises in Grayson County, Ky., flows in a southerly direction 40 miles, and empties into Green River 0.3 mile above new lock 5 and 168.4 miles above the mouth of Green River. Nolin River rises in Larue County, Ky., flows in a southwesterly direction about 105 miles, and empties into the Green River 1.8 miles above lock 6 and 183.5 miles above the mouth of Green River. Existing project.-This provides for the purchase of improve- ments made prior to 1884 by the State of Kentucky, consisting of locks and dams 1 to 4, Green River, and 1, Barren River, which gave a continuous 4-foot depth for navigation from Bowling Green, on the Barren River, to the mouth of Green River; the reconstruction of lock 2, Green River; the upstream extension of slack-water navigation on Green River to Mammoth Cave, Ky., by the construction of locks and dams 5 and 6 and by the removal 1742 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 of snags and slides; the construction of new locks at dam 1, Bar- ren River, and at dam 5, Green River; the raising of the crest of dam 5, Green River, 2 feet, by means of a movable A-frame top; the improvement of Nolin River by the removal of obstruc- tive bars, boulders, overhanging rocks, and snags; and the im- provement of Bear Creek by removing snags and widening bends. The project for Green River extends from mouth to Mammoth Cave, Ky., a distance of 197.8 miles; for Barren River from the mouth to Bowling Green, Ky., a distance of 30.1 miles; for Nolin River from the mouth to Meredith Ferry, a distance of 73/4 miles; and for Bear Creek, Ky., for a distance of 8 miles above its mouth. The navigable depth of the improved portions is limited to 5.5 feet by the elevations of the existing lock miter sills. Fluctuations in stage vary considerably at the different locks. At lock 3, Green River, ordinary fluctuations due to high stages are from 12 to 15 feet above the pool level, and at lock 1, Barren River, from 7 to 10 feet above pool. The maximum stages of record are 34 feet above normal pool stage at lock 3, Green River, and 29 feet at lock 1, Barren River. These stages were obtained during the floods of 1937 and 1913, respectively. The principal data concerning the locks and dams are shown in the following table: Location Greatest Depth Depth Width length on lower on upper Lock and Distance of lock of lock Lift at miter sill miter sill dam Nearest town from chamber available normal at normal at normal mouth of for full pool pool level pool level river width GREEN RIVER Miles Feet Feet Feet Feet Feet 1.. .... _ -_At Spottsville, Ky............. 9. 1 35. 5 139. 0 1 11. 8 9. 0 6. 7 2_------_ At Rumsey, Ky.....__------- - 63. 1 36. 0 141. 0 14. 3 5. 5 7. 8 3......- .

For map of the Green, Barren, and Rough Rivers, see H. Doc. No. 81, 73d Cong., 1st sess. Local cooperation.-The River and Harbor Act of July 3, 1930, provides that in connection with the improvement of Bear Creek, Ky., local interests are to contribute $10,000 to the first cost of the dredging, provide necessary rights-of-way at the bends, fur- nish without cost to the United States satisfactory areas for the disposal of excavated material, and assume all flowage damages along Bear Creek. These conditions have not been met. 1744 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The River and Harbor Act of August 30, 1935, provides that local interests provide any land or easements required for the purpose of the improvement of Nolin River. Local interests have been unable to obtain easements required for the removal of over- hanging rock ledges at Whistle Mountain. Terminal facilities.-There are two terminals on the Green River for handling petroleum products. On Barren River there are three terminals, two of which are petroleum terminals, and the other is the public landing at Bowling Green, Ky. There are no terminals on the Nolin River or Bear Creek. These facili- ties are considered adequate for existing commerce. Operations and results during fiscal year.-Maintenance: Work during the fiscal year consisted of the removal of shoals, snags, slides and overhanging trees as required to maintain an adequate channel in the pools of the dams. Maintenance (operating and care): Work during the fiscal year consisted of the operation and maintenance of the seven locks and dams on the Green and Barren Rivers. The costs were $26,862.53 for maintenance of channels and $156,615.33 for operating and care of locks and dams (of which $137,615.33 was from regular funds, and $19,000 from the appro- priation "Maintenance and operation of dams and other improve- ments of navigable waters,") a total of $183,477.86. The expendi- tures were $183,286.80, of which $164,286.80 was from regular funds and $19,000 from the appropriation "Maintenance and operation of dams and other improvements of navigable waters." Condition at end of fiscal year.-The canalization system on the Green and Barren Rivers is in only fair condition, except Lock 1, Barren River and Lock and Dam 5, Green River, which are in excellent condition. The controlling navigable depth in the sections covered by the existing project was 5.5 feet at the end of the fiscal year. New work remaining to be done consists of the re- moval of overhanging rock ledges at Whistle Mountain on Nolin River, provided for by the River and Harbor Act of August 30, 1935, and the improvement of Bear Creek, provided for by the River and Harbor Act of July 3, 1930.

ROUGH RIVER, KY. Location.-This stream is one of the principal tributaries of Green River and lies wholly within the State of Kentucky. It rises in Hardin County, flows westerly 136 miles, and empties into Green River at Livermore, 71 miles from the mouth of that river. (See U. S. Geological Survey charts, Kentucky quadrangles: Central City, Hartford, Whitesville.) Existing project.-This provides for clearing the river of ob- structions and for the construction of a lock and dam to carry slack water to Hartford, Ky. The new work provided for having been completed, the project now contemplates the maintenance of the lock and dam and keeping the river channel free from the snags and other obstruction to navigation from the mouth to Hart- ford, Ky., a distance of 29.5 miles. At the lock the ordinary fluctuations due to floods vary from 6 1746 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 to 10 feet above pool level. During the flood of 1937 a stage of about 26 feet above pool stage was reached. The location and principal dimensions, etc., of the lock are as follows: Name ...............................

The latest pubilshed map of Rough River is printed in H. Doc. 81, 73d Cong., 1st sess. Terminal facilities.-There are a few unimproved private land- ings which are considered adequate for existing commerce. Operations and results during fiscal year.-Maintenance (oper- ating and care): Work during the fiscal year consisted of the performance of custodial services at lock 1, Rough River. The total cost during the fiscal year was $3,839.20 for mainte- nance. The expenditures were $3,824.74. Condition at end of fiscal year.-The existing project was com- pleted in 1899. At the end of the fiscal year the lock and dam were RIVERS AND HARBORS-LOUISVILLE, KY., DISTRICT 1747 in poor condition. The lock gates could not be operated because of mud deposits in lock chamber. A slack-water channel was available elsewhere in the river for boats not exceeding a 3-foot draft. The cost to the end of the fiscal year were $105,500 for new work and $44,561.59 for operating and care, a total of $150,061.59. The expenditures were $150,036.48. In addition, the sum of $55,298.39 was expended between 1898 and June 30, 1936, on the operating and care of the works of im- provement, under the provision of the permanent indefinite ap- propriation for such purposes.

EAST FORK RESERVOIR, OHIO RIVER BASIN, OHIO Location.-The site of the East Fork Dam is on the East Fork of Little Miami River 32 miles above the Little Miami River's en- trance into the Ohio River. It is in Clermont County, Ohio, 4 miles southeast of Batavia and about 20 miles east of Cincinnati. The East Fork Reservoir will extend upstream about 13 miles and all lies in Clermont County. Existing project.-The plan of improvement provides for the construction of a dam for flood control, conservation, recreation, and related purposes. The plan for the dam provides for the con- struction of an earth embankment about 156 feet high and 1,400 feet long, a spillway through the right abutment, a gate con- trolled outlet through the earth dam and a dyke 1,400 feet long across a low point in the right abutment ridge. The dam will im- pound a permanent pool at elevation 680, having a capacity of 17,- 450 acre-feet and an area of 710 acres. The storage between eleva- tions 680 and 756 amounting to 134,480 acre-feet which is equival- ent to 7.4 inches of run-off from the 340 square miles of drainage area above the dam, will be reserved for flood control. 1750 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The estimated cost of new work, revised in 1950, $6,620,000. The existing project has been selected for construction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operationsand results during fiscal year.-Operationsconsisted of continuation of work on preliminary surveys, foundation ex- plorations and studies for preparation of detailed plans. The costs during the fiscal year were $34,247.96 for new work. The expenditures were $38,331.06. Condition at end of fiscal year.-Preliminarysurveys, explora- tions, studies and preparation of detailed plans were 40 percent complete. Construction of the project has not been started. The total costs to the end of the fiscal year were $51,056.64 for new work. The expenditures were $50,546.27. Proposed operations.-The balance unexpended on June 30, 1950, will be applied during fiscal year 1951 to accounts payable and continued work on preliminary surveys, explorations, studies and preparation of detailed plans by hired labor. The additional sum of $50,000 can be profitably expended to continue preparation of plans during fiscal year 1952 by hired labor.

NEWPORT, OHIO RIVER BASIN, KY. Location.-In Campbell County, Ky., on the left bank of the Ohio River and the right bank of the Licking River at their con- fluence, 470 miles below Pittsburgh, Pa. Existing project.-The plan of improvement provides for the construction of 8,000 feet of earth levee, 1,805 feet of concrete wall, 2,435 feet of cellular type steel sheet piling wall, three pump- ing plants, and other necessary appurtenances. The line of pro- tection begins at high ground near the east end of Lexington Ave- nue, extends in a northwesterly direction to the left bank of the FLOOD CONTROL--LOUISVILLE, KY., DISTRICT 1751 Ohio River, thence downstream to the mouth of Licking River and upstream along the right bank of Licking River to high ground in the vicinity of Lowell and Twelfth Streets. The section along Licking River from Chestnut Street to Hodge Street is cellular type steel sheet piling and the section from Hodge Street to Lowell and Twelfth Streets is concrete wall. 'The project will provide protection for the city of Newport, Ky., against Ohio River and Licking River floods equal to the maximum of record which occurred in 1937. The current (1950) estimated Federal cost of the project is $7,000,000; the estimated non-Federal cost is $809,000. The existing project has been selected for construction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938. Local cooperation.-See page 8 for requirements. The city of Newport has acquired all necessary rights-of-way. Operations and results during fiscal year.-Construction of the project was continued during the year. Delivery of steel sheet piling for the cellular type sheet piling wall was completed and the contract for construction of this wall was advanced to 56 per- cent completiori. Construction of the Lowell Street interceptor sewer and the pumping plants was completed. Construction of the remaining section of concrete wall along Licking River was started in February 1950 and advanced to 37 percent completion. The partially completed project effectively prevented flooding of a portion of the city during the January 1950 flood, thereby pre- venting flood damages estimated at $310,000. The costs during the fiscal year were $2,646,980.33 for new work. The expenditures were $2,552,414.21. Condition at end of fiscal year.-Constructionof the project was started in April 1946 and was about 75 percent complete at the end of the fiscal year. The levee and appurtenances along the Ohio River, the Lowell Street interceptor sewers, the pumping plants and delivery of steel sheet piling for the cellular type sheet piling wall have been completed. The cellular wall and the concrete-wall along Licking River are 56 and 37 percent complete, respectively. All major items of work on the project are under contract. The work remaining, in addition to that now under contract, consists of miscellaneous cleanup and formal assignment of project to local interests for maintenance and operation. The total costs to the end of the fiscal year were $5,568,097.70 from regular funds and $6,150.48 from emergency relief funds, a total of $5,574,248.18, all for new work. The expenditures were $5,329.764.52 from regular funds and $6,150.48 from emergency relief funds, a total of $5,335,915.

The site of the West Fork of Mill Creek Dam is on the West Fork of Mill Creek 6.5 miles above its junction with Mill Creek and 2 miles northeast of Mount Healthy, Ohio, and about 10 miles north of downtown Cincinnati. The reservoir will extend upstream about 3 miles and all lies within Hamilton County, Ohio. Existing project.-The plan of improvement provides for the construction of a dam for flood control, reduction of pumping requirements at the Mill Creek barrier dam and recreation. It will be an earth embankment with a maximum height of about 100 feet and a total length of 1,100 feet. The plan for the dam includes a gate controlled concrete conduit 10.5 feet in diameter under the embankment along the right abutment and an un- controlled spillway through the right abutment ridge. A per- manent pool at elevation 675 having an area of 183 acres is included in the plan. The storage between elevations 675 and 702 amounting to 9,850 acre-feet, which is equivalent to 6.3 inches of run-off from the 29.5 square miles of drainage area above the dam, will be reserved for flood control and reduction of pumping requirements at the Mill Creek barrier dam. Also included in the plan are the acquisition of necessary land not controlled by local interests, clearing of the permanent pool area, relocation of sanitary sewer outside the reservoir area and altera- tion of affected roads and utilities where required for access to property and developments in the vicinity of the reservoir. The estimated cost of new work, revised in 1950, is $4,041,700, of which $600,000 is to be contributed by local interests. The latest published map is contained in House Document No. 198, Eightieth Congress, first session. The existing project has been selected for construction under the additional authorization for the Ohio River basin contained in the Flood Control Act approved July 24, 1946. Local cooperation.-Local interests are required to release necessary land under their control at no cost to the United States and give assurances that they will prevent future channel en- 1758 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 croachment below the dam site in connection with the flood control reservoir. In case the reservoir is enlarged to include a conserva- tion pool, local interests must contribute one-half the additional cost of such pool, including one-half of the cost of relocation of sanitary sewer, and agree to hold and save the United States free from damages resulting from its provision. The Board of County Commissioners of Hamilton County, Ohio, adopted a resolution on October 8, 1947, signifying willingness to fulfill local coopera- tion requirements including the provision of the conservation pool. Assurances of local cooperation were executed on the same date. A contract with the United States for the relocation of the sani- tary sewer outside the reservoir area in order to include the con- servation pool in the project has been accepted by Hamilton County in which the United States pays one-half the cost of such relocation work. Operations and results during fiscal year.-Constructionof the sanitary sewer relocation outside the reservoir area was continued, the remaining sections having been placed under contract by Hamilton County. Plans and specifications for the dam and appurtenances were completed and construction of the dam started in June 1950. Negotiations for purchase of reservoir lands were continued during the year. Negotiations with road and utility owners were started to effect relocation of these facilities outside the reservoir. The costs during the fiscal year were $648,644.49 for new work. The expenditures were $647,393.88. Condition at end of fiscal year.-Construction of the sanitary sewer relocation outside the reservoir area was started in March 1.949 and was nearing completion at the end of the fiscal year. Construction of the dam, outlet and spillway was started in June 1950. Acquisition of lands was 53 percent complete and negotia- tions were well advanced on contracts for relocations of roads and utilities required for operation of the reservoir. The work re- maining consists of the completion of sewer relocation, dam con- struction and land acquisition, construction of necessary relocations, clearing of the permanent pool area and miscellaneous cleanup. The total costs to the end of the fiscal year were $790,097.77 for new work. The expenditures were $785,554.83.

Location.-The site of the Jessamine Creek Dam is on Kentucky River 136 miles above its mouth and about 20 miles south of Lex- inton, Ky. The reservoir will extend upstream from the dam about 126 miles and will lie in Jessamine, Garrard, Madison, Fayette, Clarke, Estill, Powell and Lee Counties. Existing project.-The plan of improvement provides for the construction of a dam for flood control, conservation and recrea- tion and development of hydroelectric power. A concrete gravity type dam with a maximum height of 170 feet and a length of about 900 feet is proposed. The spillway will be ogee type controlled by crest gates. The initial plan provides for development of the proj- ect for flood control, conservation and recreation with a small permanent pool. Most of the project storage of 1,135,000 acre- feet up to elevation 630 would be reserved for flood control. The ultimate plan of development includes the provision of facilities for generation of electric power at which time the permanent pool will be increased to elevation 598. Also included in the project are the acquisition of necessary lands, clearing the permanent pool area and relocation of necessary roads, railroads and ultilities required for the reservoir storage. The estimated cost of new work, revised in 1950, is $30,500,000. The latest published map is contained in House Document No. 504, Seventy-eighth Congress, second session. The existing project is eligible for selection for construction under the general authorization for the Ohio River Basin con- tained in the Flood Control Act approved June 28, 1938.

Location.-The project is located in Pope, Massac, Johnson, and Pulaski Counties, Ill., ip the Bay Creek-Cache River Valley. These streams form a connecting valley across the southern tip of the State of Illinois from the Ohio River at mile 910 on the east to mile 975 on the west. During high floods, backwater from the Ohio River overflows the flood plain of the Bay Creek-Cache River Valley. Existing pro ject.-The plan of improvement provides for the construction of two levees, one known as the Reevesville levee and the other as the Cache River levee. The Reevesville levee begins at high ground about 1 mile north of Reevesville, Ill., and extends eastward to the double-track main line of the Illinois Central Rail- road, thence continues in a general southerly direction for a dis- tance of 2 miles crossing the Golconda branch of the Illinois Cen- tral Railroad, thence east along the Bay Creek Relief Channel at a distance of about 200 to 800 feet from the right bank to State Highway 145, and thence in a southeasterly direction to high ground about 1,000 feet south of the Bay Creek Relief Channel. 1808 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 This levee is 4.9 miles long and has an average height of 11 feet. The Cache River levee begins at high ground on the right bank of the Post Creek cut-off approximately 700 feet upstream from the Chicago and Eastern Illinois Railroad crossing of this stream and parallels the old spoil bank levee for about 2,000 feet along Post Creek at a distance of about 150 feet, thence continues upstream along the landside of the spoil bank levee on the right bank of Forman Floodway ending at the gravel road along the New York Central Railroad. The total length of the Cache River levee is 3.7 miles with an average height of 10 feet. In addition, the plan in- cludes a short levee about 550 feet long across a low swale, a short distance east of Karnak, Ill., and other appurtenant structures. The project will provide protection for the city of Reevesville, Ill., the urban centers of Belknap, Karnak, and Ullin, Ill., seven smaller towns, four railroads, several miles of main highways and 23,500 acres of tillable land, against Ohio River and Bay Creek floods equal to the maximum of record which occurred in 1937. The estimated Federal cost of new work, revised in 1950, is $650,000; the estimated non-Federal cost is $40,000. The existing project has been selected for construction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938.

MOUNDS AND MOUND CITY, OHIO RIVER BASIN, ILL. Location.-This project is located in Pulaski and Alexander Counties, Ill., on the right bank of the Ohio River about 8 miles above the mouth. Existing project.-The, plan of improvement provides for the construction of a system of levees and concrete flood walls and channel diversion, consisting of the following features: The Ohio River section, including 4,860 feet of new earth levee, 20,120 feet of levee enlargement, and 785 feet of concrete wall, extending from high ground about 3 miles north of Mound City along the riverside of State Highway No. 37 and the right bank of the Ohio River to a point about 2,000 feet northwest of the mouth of Cache River; the Cache River diversion, unit 1, including the excavation of 3,890 feet of channel and the construction of 4,830 feet of new earth levee, and unit 2, including the excavation of 1,370 feet of channel and the construction of 600 feet of new earth levee, and unit 3, including the construction of 2,450 feet of new earth levee extend- ing downstream along the Ohio River from the lower end of the Ohio River section across the old bed of the Cache River to the northeast corner of the Cairo drainage district levee; construction of one new highway bridge and two new railroad bridges across the diversion channel; two pumping plants for disposal of interior. drainage; and the other appurtenant structures. Units 1 and 2 of the Cache River diversion include excavation of the diversion chan- nel from the abandoned Illinois Central Railroad bridge location over the Cache River near Cache, Ill., to the Mississippi River near the Beechridge gage and construction of a new earth levee from high ground just east of the upstream end of the diversion channel to the northwest corner of the existing Cairo drainage district levee. The project will provide protection for Mounds and Mound City, Ill., and about 8,600 acres of agricultural land against Ohio and 1810 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Mississippi River floods equal to the maximum flood of record, which occurred in 1937. The estimated Federal cost of the project, revised in 1950, is $4,170,000, of which an amount not exceeding $635,000 may be applied to lands and damages; the estimated non-Federal cost is $9,300. The existing project was authorized by the Flood Control Act approved June 28, 1938. Local cooperation.-Provisionsof section 2 of the Flood Control Act approved June 28, 1938, apply to the diversion of the Cache River; whereas the provisions of section 3 of the Flood Control Act approved June 22, 1936, apply to levees and flood walls. Rights-of- way for the levee and flood wall were approved on June 7 and July 25, 1940. Operations and results during fiscal year.-Constructionof the Missouri Pacific Railroad bridge, across the diversion channel was completed and construction of unit IIB of Cache River diversion was initiated and a contract was awarded on unit III of the Cache River diversion, but no construction work had been started. The partially completed work together with previously constructed levees, was effective in preventing flooding of the Mounds and Mound City and a part of the surrounding agricultural area dur- ing the January 1950 flood thereby preventing damages estimated at $2,885,000. The costs during the fiscal year were $610,477.45 for new work. The expenditures were $472,227.15. Condition at end of fiscal year.-Construction of the project was started in June 1940 and at the end of the fiscal year, the Ohio River section, Units I and IIA of Cache River diversion, the highway and railroad bridges across the diversion channel had been completed, Unit IIB of the Cache River diversion was 52 percent completed and a contract was in force for construction of Unit III. The work in place was in good condition except for minor wave wash on the Ohio River section and some deposition in the diversion channel. The work remaining consists of completion of work under contract and the construction of the pumping plants. The total costs to the end of the fiscal year were $2,928,574.01 for new work. The expenditures were $2,710,309.74.

OHIO RIVER OPEN CHANNEL WORK For report on this improvement, see page 1685. 3. MUSKINGUM RIVER, OHIO Location.--The Muskingum River, 112.45 miles in length, and lying entirely in the State of Ohio, is formed by the junction of the Walhonding and Tuscarawas Rivers at Coshocton, Ohio, flows in a southerly direction and empties into the Ohio River at Mari- etta, Ohio, 172.2 miles below Pittsburgh, Pa. Existing project.-This authorized the taking over, restoration, maintenance, and operation of the State works and plant to pro- vide slack-water navigation between lock 1, at Marietta, Ohio, and Dresden, Ohio, a distance of 92.85 miles. Navigation is afforded by 11 locks and dams and 4 short lateral canals. The maximum depth which it is now possible to maintain without ex- tensive improvement is 4.5 feet, although in certain portions 5.5 feet is available. Above the site of the old lock 11 the minimum depth actually maintained is 2 feet. The navigable depth between lock 1 and the mouth, a distance of 0.25 mile, is provided by dam 18, Ohio River, and by dredging. The original estimate of cost of restoring the dams taken over from the State of Ohio was $200,000. To this was added later the construction of a new lock and dam 11, at a cost of about $143,000, the repair and extension of a levee at dam 10, and some minor work, the net total expended from specific appropriations having been' $301,911.53. The estimated annual maintenance costs, cur- rent (1950), are $25,000 for channel maintenance and $114,000 for operation and care of locks and dams. The construction of a new lock 1 was done in connection with the construction of an ice harbor as part of the Ohio River improvement and was not a part of this project. Operating and care of the locks and dams were RIVERS AND HARBORS--HUNTINGTON, W.

VA., DISTRICT 1831 Local cooperation.-Fully complied with. Terminal facilities.-There are numerous public and private landings, generally unimproved, at points accessible to the public highways, and in a few instances having railroad connections. Three yards, principally equipped for unloading sand and gravel, are situated at miles 0.2, 74.7, and 76.4. Numerous land- ings, not equipped, are used to stock pile sand and gravel for State and county roads. Two private terminals for handling petroleum products exist on the river at miles 1.8 and 75.6. The terminal facilities are considered adequate for existing commerce. Operations and results during fiscal year.-Maintenance: Dredging of bars in the channel of pools Nos. 7 and 9 was accom- plished by hired labor, 5,586 cubic yards of material being re- moved. The cost of maintenance during the fiscal year was $3,423.03. Operating and care: The locks and dams were operated as re- quired and essential repairs were made thereto and to the appur- tenant structures to maintain them in a serviceable, condition. Hired labor dredging, totaling 74,246 cubic yards, was performed in the approaches and lock chambers of locks Nos. 1 to 10, in- clusive, in order to permit the passage of commercial tows. The cost for operating and care during the fiscal year was $103,693.53. The total cost of maintenance for the fiscal year was $107,116.56. The expenditures were $108,394.43. Condition at end of fiscal year.-The existing project was com- pleted in 1910. The locks and dams are in fair to poor condition and all structures are in operation except lock 11. Resident care at locks 2, 5, 6 and 11 has been discontinued on an annual basis while locks 8 and 9 are unattended for an approximate period of 4 months each year, during the winter season, when traffic is ex- tremely light. The facilities at all unattended structures, except lock 11, are available to navigation interests, subject to 24 hours' advance notice. A heavy deposit of sand and silt in the lock chamber and approaches at lock 11 prohibits the operation of the lock gates. The available depth for navigation is 4.5 feet from the mouth to lock 11, and from lock 11 to the end of the project the depth actually maintained is 2 feet. For details of locks and dams, see table under paragraph "existing project." The total cost under the existing project to the end of the fiscal year was $2,019,442.62, of which $301,911.53 was for new work, $151,693.73 for maintenance, and $1,565,837.36 for operation and care of locks and dams. The expenditures were $2,016,538.63. In addition, the sum of $3,995,355.89 was expended between April 7, 1887, and June 30, 1936, on the operation and care of the works of improve- ment under the provisions of the permanent indefinite appropria- tion for such purposes. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950, plus an anticipated allotment of $271,- 100 during fiscal year 1951, will be expended as follows: Accounts payable June 30, 1950 ........................ .. $3,431.31 Maintenance: Dredging channels in pools 7, 9 and 10 (hired labor, July 1, 1950 to June 30, 1951) .................... 4,646.35 1832 REPORT OF CHIEF OF ENGINEERS, U.

LITTLE KANAWHA RIVER, W. VA. Location.-This river, 167 miles in length, rises on the western slope of Laurel Hill, W. Va., flows in a general northwesterly di- rection, and empties into the Ohio River at Parkersburg, W. Va. Previous projects.-Adopted by the River and Harbor Act ap- proved August 14, 1876. For further details, see page 1912 of Annual Report for 1915 and page 1307 of Annual Report for 1938. Existing project.-This provides for five locks with fixed dams, to give a navigable depth of 4 feet from the mouth of the river to Creston, a distance of 48 miles. Under this project one lock and dam (5) was constructed and four locks and dams (1 to 4) were purchased from the Little Kanawha Navigation Co. The cost of purchase and repair of locks and dams 1 to 4 was $282,059.50, and the cost of constructing lock and dam 5 was $167,875. The current (1950) estimate of annual cost of operation and care of the locks and dams is $81,000. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-HUNTINGTON, W.

Terminal facilities.-Terminal facilities consist of two gasoline and oil unloading stations at miles 1.5 and 2.2, a dock at mile 3 for unloading acid and a drydock at mile 0.1 for boat and barge repairs. The terminal facilities are considered adequate for exist- ing commerce. Operations and results during fiscal year.-Operating and care of locks and dams: Lock and dam 1 was operated to meet the needs of existing commerce. The cost of operating and care during the fiscal year was $8,562.25. The expenditures were $8,263.28. Condition at end of fiscal year.-The existing project was com- pleted in 1891. Lock and dam 1 is in fair condition and navigation on the river is normally possible only through the pool above this structure. Resident care has been discontinued at locks and dams 2 to 5, inclusive. Dams 2, 3 and 5 are in such poor condition that project depth cannot be maintained during the low-water season. Dam 4 is breached and project depth cannot be maintained in this pool at any time. Heavy deposits of sand and silt in the lock chambers and approaches at locks 2 to 5, inclusive, prohibit 939127-51-vol. 2-.--26 1834 REPORT OF CHIEF OF ENGINEERS, U. S.

KANAWHA RIVER, W. VA. Location.-This river, 97 miles in length, is formed by the junction of the New and Gauley Rivers, a short distance above Kanawha Falls, W. Va., flows in a general northwesterly direction, and empties into the Ohio River at Point Pleasant, W. Va. Previous projects.-The original project was adopted by the River and Harbor Act of March 3, 1873, and modified by the River and Harbor Act of March 3, 1875 (Annual Report for 1875, pt. 2, pp. 90-98). For further details see page 1913, Annual Report for 1915, and page 1309, Annual Report for 1938. Existing project.-The existing project provides for three dams on the Kanawha River, with twin locks having usable dimensions RIVERS AND HARBORS-HUNTINGTON, W. VA., DISTRICT 1835 of 56 by 360 feet, and one dam on the Ohio River near Gallipolis, Ohio, with one lock 110 by 600 feet and one lock 110 by 360 feet, to furnish a 9-foot navigable depth from the mouth to a point 90.57 miles above. The estimate of cost for new work, revised in 1946, is $24,- 167,450, exclusive of amounts expended on previous projects. The current (1950) estimated annual maintenance costs are $25,500 for channel maintenance and $300,000 for operation and care of locks and dams.

O1 2 Hydroelectric plant, licensed by Federal Power Commission, at this site. 4 Two locks each, 56 feet by 360 feet CJI RIVERS AND HARBORS-HUNTINGTON, W. VA., DISTRICT 1837 Local cooperation.-Under license 1175, issued by the Federal Power Commission, the Kanawha Valley Power Co. has con- structed hydroelectric plants at London and Marmet locks and dams, a license fee of $32,000 per annum having been fixed for each site. The Kanawha Valley Power Co. has also constructed a hydroelectric plant at Winfield locks and dam, under license 1290, a license fee of $40,000 per annum having been fixed. Terminal facilities.-The public terminal facilities consist of a paved landing at Charleston, W. Va. Numerous coal tipples, owned by private interests, exist, available for use only to the owners for loading into barges the coal mined by them. Other privately owned facilities are as follows: Two coal unloading terminals at Belle and one at Cabin Creek; eleven gasoline and oil unloading stations at Boomer, Cabin Creek, Charleston, North Charleston, South Charleston, and St. Albans; two docks at Nitro for handling acid; a dock at South Charleston and one at Nitro for unloading sul- phur; nine terminals at Belle, North Charleston, Blaine Island, and Institute for handling chemicals; and a terminal at Alloy generally used for unloading coke. The terminal facilities are considered adequate for existing commerce. Operations and results during fiscal year.-New work: Work in connection with the acquisition of flowage easements occasioned by the increased pool heights was continued. The net cost of new work during the fiscal year was a credit of $1,229.33. This credit results from action taken to eliminate the furnishing of final certificates of title by contract. Maintenance: Navigation aids were inspected periodically and channel sweeping and snagging operations were conducted, by hired labor, as required. The channel below London Locks and at Paint Creek Shoals was dredged by contract, a total of 29,209 cubic yards of material being removed. The cost of maintenance during the fiscal year was $49,018.01. Operating and care: The locks and dams were operated as required, and necessary repairs and improvements were made thereto, and to the appurtenant structures and grounds. In addi- tion to the ordinary repairs conducted, the following major items of work were performed by hired labor: Repaired mooring pins in lock walls at London and Marmet Locks; replaced tow haulage units on lock wall at Marmet Locks; and cleaned and painted upstream side of roller gates and upstream emergency bulkhead sections at Winfield Locks. Work accomplished by contract con- sisted of constructing mooring facilities above Winfield Locks. The cost for operating and care during the fiscal year was $297,- 483.9. Th total cost for the fiscal year, all from regular funds, was $345,272.59, of which a credit of $1,229.33 was for new work and $346,501.92 for maintenance. The total expenditures were $344,- 092.87. Condition at end of fiscal year.-The existing project was about 98 percent complete. The work remaining to be done consists of completing the procurement of flowage easements. All structures are in operation and the available, depth for navigation is 9 feet from the mouth of the river to the head of the improvement. 1838 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Above the improved portion of the river, the minimum depth in the channel is less than 1 foot. For details of the locks and dams, see table under paragraph "Existing project."

MASSILLON, OHIO RIVER BASIN, OHIO Location.-Massillon, Ohio, is located in Stark County, on the Tuscarawas River, 200 miles above the mouth of the Muskingum River. Existing project.-The plan of improvement provides generally for improvement of the channel of the Tuscarawas River, con- structing complementary levees, pump stations and appurtenances, and remedial work. The project has been subdivided into six con- struction units, namely, (1) constructing two pressure conduits, FLOOD CONTROL-HUNTINGTON, W. VA., DISTRICT 1845 (2) section 1, widening and deepening the present channel for a distance of 8,500 feet, constructing 1,900 feet of new channel and 3,600 feet of levees, relocating 3.5 miles of railroad lines with facilities, including constructing four railroad bridges, the sub- structure of the Pennsylvania Railroad bridge across the Tuscara- was River, one freight terminal building and an engine terminal, constructing one highway bridge, and the removal of railroad and highway bridges, buildings and facilities, (3) constructing the superstructure of the Pennsylvania Railroad bridge across the Tuscarawas River, (4) section 2, unit 1, widening and deepening the present channel and bank protection work for a distance of 1,700 feet, relocating 1.8 miles of railroad lines, replacing one highway bridge with a viaduct, removal of three railroad bridges, one highway bridge and 10,550 feet of abandoned track and the reconstruction of affected water service, sewer and public utility lines, (5) section 2, unit 2, widening and deepening the present channel for a distance of 2,600 feet, constructing 2,400 feet of new channel, 12,300 feet of levee and 200 feet of concrete wall, relocat- ing 3,600 feet of railroad lines, construction of a control weir, replacing one highway bridge with a viaduct, raising one high- way bridge and the reconstruction of affected water service, sewer and public utility lines, and (6) constructing four pump stations. In addition, the United States has entered into agreements with affected property owners for the performance of certain remedial work connected with the project. The project will provide protection (with 3-foot freeboard) against a flood with peak discharge 20 percent greater than maxi- mum of record. The existing project was selected for construction under the general authorization for the Ohio River Basin, con- tained in the Flood Control Act approved June 28, 1938. The esti- mated cost of new work, revised in 1950, is $8,662,900, which in- cludes a contribution of $497,850, by local interests, for additional construction and alterations beyond the scope of the authorized Federal project. A total of $495,600 of the contribution has been received. The $2,250 remaining to be contributed pertains to the installation of a lighting system in connection with the construc- tion of two viaducts. The estimated average annual Federal cost of maintenance, made in 1949, is $5,000. Local cooperation.-Section 2 of the Flood Control Act ap- proved June 28, 1938, applies. Operations and results during fiscal year.-Work under con- tract for constructing unit 5 of the project was continued through- out the period. A contract was awarded and work initiated on construction of unit 6 of the project. Work under agreements with various railroad and utility companies for relocating their facilities was continued. Work in connection with the acquisition of land was continued. The cost of new work during the fiscal year was $1,760,162.70. The expenditures were $1,687,041.48. Condition at end of fiscal year.-Constructionof the project was initiated in July 1940, but was suspended during the war emer- gency. Construction was resumed in 1946. Of the six construction units described in the paragraph "Existing project," units Nos. 1846 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 1, 2, 3, and 4 are complete. Units Nos. 5 and 6, being constructed by contract, were 67 percent and 10 percent complete, respectively, at the end of the year. Work in connection with the relocation of railroads and utilities interfering with construction of the project is about 63 percent complete. The acquisition of land is in progress and of the estimated 166 tracts required, 148 tracts have been acquired. Work on the entire project is about 81 percent complete. The total cost of new work to the end of the fiscal year was $7,002,533.81. The expenditures were $6,762,211.01. The foregoing cost and expenditures include the amount of $495,600 contributed by the Massillon conservancy district. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950, plus an anticipated allotment of $624,- 800, will be expended as follows: Accounts payable June 30, 1950 ........................... $241,440.99 New work: Surveys, studies and preparation of plans and specifi- cations (hired labor, July 1, 1950 to June 30, 1951) .... 1,500.00 - Cnomnlplete construction of TTnit (conntract .

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 Pitts- burgh, 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- 1848 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19 50 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. 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 any 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 dis- trict 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 current (1950) total estimated cost of the project to the Government excluding the cost to the Muskingum watershed con- servancy district, is $41,438,300, of which $19,227,600 is for con- struction and $22,210,700 for lands and damages. The current (1950) estimated annual operation and maintenance cost is $245,- 000. For further details see Annual Report for 1946, page 1734.

For further details see Annual Report for 1942, page 1257. Operations and results during fiscal year.-New work: Work in connection with the acquisition of flowage easements was con- tinued. Preparation of a comprehensive plan of improvement of the reservoir system was continued and advanced to about 58 percent completion. Construction of improvements to Magnolia and Zoar levees was initiated, by contract, just prior to the end of the fiscal year. Maintenance: The 14 reservoirs were operated as required to reduce local flooding and necessary repairs were made to the structures and appurtenances. During January and February 1950, the reservoirs were operated to reduce flood stages on the Muskingum and Ohio Rivers. The maximum amount of flood control storage utilized in the reservoirs during this period was 247,320 acre-feet. These operations resulted in reductions in stages at locations in Ohio as follows: Newcomerstown, 1.6 feet; Coshocton, 4 feet; Dresden, 2.9 feet; Zanesville, 1 foot; and Marietta, 0.4 foot. The total cost, all from regular funds, was $580,518.78, of which $308,144.52 was for new work and $272,374.26 was for mainte- nance. The expenditures were $577,671.75. Condition at end of fiscal year.-Construction of the project was initiated in January 1935. With the completion of the Dover Reservoir in November 1938, all of the 14 flood-control dams, included in the project, were complete and in operation. The major items of presently authorized work remaining to be done consist of completing acquisition of flowage easements; remedial work in the channel downstream from the Charles Mill Dam; and improvements to Magnolia and Zoar levees. Work in con- nection with the acquisition of land was in progress and of the 4,711 tracts authorized for acquisition, 4,514 tracts have been acquired. Construction of channel remedial work has not been initiated. Improvements to Magnolia and Zoar levees are in progress and are about 4 percent and 2 percent complete at the respective locations. Work presently authorized under this proj- ect is about 92 percent complete. The costs and expenditures to the end of the fiscal year were as follows: Regular funds: The cost was $11,766,347.15, of which $10,- 343,394.70 was for new work, and $1,422,952.45 was for mainte- nance. The expenditures were $11,723,308.50. National Industrial Recovery funds: The cost and expenditures for new work were $27,190,000.

BURR OAK RESERVOIR, OHIO RIVER BASIN, OHIO Location.-The dam site of the Burr Oak Reservoir is located on East Branch of Sunday Creek, a tributary of Hocking River, Ohio, about 3 miles north of the village of Glouster and 57.2 miles above the mouth of Hocking River. Existing project.-The plan of improvement provides for the construction of a rolled earth fill dam having a maximum height of 84 feet and a total length of 944 feet; controlled outlet works discharging through a tunnel located in the left abutment; and an uncontrolled spillway in the ridge running south from the dam site. The reservoir created, providing for the storage of 17,600 acre-feet for flood control and 9,300 acre-feet for conservation and water supply for a total of 26,900 acre-feet will control 32.8 square miles of the drainage area of East Branch, and necessitates the relocation of 0.5 mile of county roads and 0.7 mile of pipe line. The reservoir will afford substantial protection to the Sunday Creek Valley and serve as a unit of the coordinated reservoir system for the protection of the Hocking River and Ohio River Valleys. The reservoir will also provide an assured water supply to villages, industries, and coal-mine operations in the Sunday Creek Valley. The existing project was authorized under the Flood Control Act approved December 22, 1944. The estimated cost of new work, revised in 1950, is $2,876,000 of which $2,091,000 represents Federal cost and $785,000 represents cost to local interests. The average annual estimated Federal cost of operating and care of the dam and reservoir, made in 1949, is $30,500. Local cooperation.-Local or State interests are required to furnish funds for the project equal to the difference between the total estimated first cost and the capitalized flood-control benefits. House Bill 496 passed by the Ohio State Legislature appropriated funds to cover local and State-obligations relative to the project. By agreement entered into January 22, 1948, between the Depart- ment of the Army, Corps of Engineers, and the Division of Con- servation and Natural Resources Department of Agriculture, State of Ohio, the State contributed $495,000 to be applied toward the cost of construction of the project, and retained $290,000 of FLOOD CONTROL-HUNTINGTON, W.

BLUESTONE RESERVOIR, OHIO RIVER BASIN, W. VA. Location.-On New River, W. Va. and Va., about 2.5 miles above Hinton, W. Va., and 1 mile above the confluence of the New and Greenbrier Rivers. Existing project.-The plan of improvement provides for the construction of a concrete gravity dam having a maximum height of 180 feet and an over-all length of 2,048 feet, consisting of 790 feet of spillway section, 330 feet of powerhouse intake structure, and 928 feet of non-overflow sections and abutments. The reser- voir created, extending approximately 36 miles upstream from the dam and providing for the gross storage of 631,000 acre-feet, will be operated as a unit of the coordinated reservoir system for the protection of the New, Kanawha, and Ohio Valleys generally. The estimated cost of new work, revised in 1950, is $29,065,000. The average annual estimated Federal cost of operating and care of the dam and reservoir, made in 1949, is $87,100. The existing project was authorized by the Flood Control Acts approved June 22, 1936, and June 28, 1938. Prior to the foregoing authorizations, under provisions of Executive Order No. 7183A, dated Septem- ber 12, 1935 (which authorized the construction of a reservoir dam on New River for the reduction of flood heights in the Kana- wha and Ohio Valleys, and for the development of power), sur- veys, foundation explorations, clearing of reservoir area, design of dam, and the acquisition of land were undertaken. The sum of $543,960.27 from emergency relief funds was allotted for ini- tiating this work. For further details, see page 1453 of the Annual Report for 1939. Local cooperation.-Section 2 of the Flood Control Act ap- proved June 28, 1938, applies. Operations and results during fiscal year.-New work: A con- tract for constructing grounds and utilities was awarded and work thereunder was initiated and completed. Construction of opera- tor's quarters and a public shelter, by contract, was initiated. A gasoline-electric standby unit was furnished under the terms of a FLOOD CONTROL-HUNTINGTON, W. VA., DISTRICT 1865 supply contract. Work under supply contracts for furnishing crest gates, trash chute gate, hoists for crest gates, and a gantry crane was continued throughout the fiscal year. Studies, investigations, and negotiations in connection with readjustment of railroad, highway, and utility facilities affected by the reservoir were con- tinued. The acquisition of land was continued, and during the fis- cal year 86 tracts were acquired. Maintenance (operating and care) : The reservoir operated as a retarding basin during the floods of January-February 1950 and the maximum amount of flood control storage during the period was 64,600 acre-feet. As a result of this storage, reductions in stages were affected at locations in West Virginia as follows: Hinton, 0.9 foot; Kanawha Falls, 1.9 feet; Charleston, 2.4 feet; and Point Pleasant, 0.9 foot. Operations under the reservoir man- agement program, including reservoir inspection and patrol work, leasing of commercial recreational sites, and leasing of lands for grazing and agricultural purposes, were conducted throughout the fiscal year. The total cost was $996,606.51, of which $952,556.77 was for new work an $44,049.74 was for maintenance. The expenditures were $1,117,876.66. Condition at end of fiscal year.-Construction of the project, which was initiated in January 1942, was suspended in 1943 due to the war emergency. Construction was resumed in January 1946. Construction of the dam and appurtenances was completed in De- cember 1948, except for the crest gates. The major items of con- struction work remaining to complete the project consist of com- pleting construction of the operator's quarters and a public shelter; installation of crest gates, hoists, and trash chute gate; and com- plete construction of reservoir management and public use facili- ties.

Existing project.--The plan of improvement provides for the construction of a rolled earth-fill dam having a maximum height of 118 feet and a total length of 913 feet; controlled outlet works discharging through a tunnel in the left abutment; an uncontrolled spillway discharging through a channel excavated in the left or west abutment; and a rolled earth-fill dike which will block a low divide to Brandykeg Creek and the Levisa Fork. The reservoir created, providing for the storage of 88,000 acre-feet, will con- trol 207 square miles of the drainage area of Johns Creek, and necessitates the relocation or reconstruction of 8.3 miles of roads, 9.7 miles of pipe lines, and 5.2 miles of telephone lines. The reser- voir will be operated as a unit of the coordinated reservoir sys- tem for the protection of the Levisa Fork, Big Sandy, and Ohio Valleys generally. The existing project was selected for construc- tion under the general authorization for the Ohio River Basin FLOOD CONTROL-HUNTINGTON, W. VA., DISTRICT 1869 contained in the Flood Control Act approved June 28, 1938. The estimated cost of new work, revised in 1950 is $6,716,000. The average annual estimated Federal cost of operating and care of the dam, and reservoir, made in 1949, is $60,200. Local cooperation.-Section 2 of the Flood Control Act ap- proved June 28, 1938, applies. Operations and results during fiscal year.-New work: Work under contracts for construction of an earth dam and appurte- nances and for removal of cemeteries from the reservoir area was completed. Construction of dwellings and utilities, by contract, was initiated and advanced to about 28 percent completion. Stud- ies, investigations, and negotiations pertinent to the relocation of roads and utility facilities, affected by the reservoir, were com- pleted. Work in connection with acquisition of land for the proj- ect was continued, 160 tracts being acquired. Maintenance (operating and care) : The reservoir operated as a retarding basin during the floods of January-February 1950, and the maximum amount of flood control storage during the period was 9,100 acre-feet. As a result of this storage, it is estimated that crest stages at Paintsville, Ky., and Louisa, Ky., were reduced 0.4 foot and 0.5 foot, respectively. Operations under the reservoir management program, including reservoir inspection and patrol work and leasing of lands for grazing and agricultural purposes, were conducted throughout the fiscal year. The total cost was $1,311,909.26, of which $1,292,572.53 was for new work and $19,336.73 was for maintenance. The expenditures were $1,434,314.67. Condition at end of fiscal year.-Constructionof the project was initiated in March 1946. The dam and appurtenances were com- pleted in July 1949. Construction of the project is complete ex- cept for completing construction of dwellings and utilities, by contract, and performance of minor items of construction by hired labor. Relocation agreements have been entered into with all seven owners having highway and utility facilities affected by the proj- ect. Work in connection with the acquisition of land is in progress and of the estimated 650 tracts required for the project, 311 tracts have been acquired. The entire project is about 87 percent com- plete. The total cost to the end of the fiscal year was $5,841,682.29, of which $5,822,345.56 was for new work and $19,336.73 was for maintenance.

DELAWARE RESERVOIR, OHIO RIVER BASIN, OHIO Location.-The dam site is located on Olentangy River about 6 miles above and north of Delaware, Ohio. The reservoir is lo- cated in Delaware, Marion, and Morrow Counties, Ohio, and 32 miles above the confluence of the Olentangy and Scioto Rivers at Columbus, Ohio. Existing project.-The project provides for the construction of a flood-control dam having a gate controlled concrete gravity ogee type spillway containing five outlet conduits, with concrete gravity non-overflow abutment sections flanked by rolled earth fill embankments. The dam is about 18,600 feet long having a maximum height of 92 feet. The reservoir created, providing for the storage of 132,000 acre-feet of water from a tributary drain- age area of 381 square miles, necessitates the construction of levee protection works, complete with pump stations and drainage structures for the Village of Waldo, Ohio, the relocation or recon- struction of 7.6 miles of roads, 6.5 miles of power lines, 7.0 miles of telephone lines and 7.6 miles of pipe lines, and the reloca- tion of 4 cemeteries containing approximately 1,744 graves. The reservoir will be operated as a unit of the coordinated reservoir system for the protection of the Olentangy, Scioto and Ohio Val- leys generally. The existing project was authorized by the Flood Control Act approved June 28, 1938. The estimated cost of new work, revised in 1950, is $7,979,000. The current (1950) average annual estimated cost of operating and care of the dam and reser- voir is $36,500. Local cooperation.-Section2 of the Flood Control Act of June 28, 1938, applies. FLOOD CONTROL-HUNTINGTON, W. VA., DISTRICT 1879 Operations and results during fiscal year.-New work: The fol- lowing items of work under contract at the beginning of the fiscal year were completed: Construction of operator's quarters and ap- purtenances; construction of five county and township roads; and construction of a gaging station. Construction of two pump sta- tions at the Waldo, Ohio, levee protection works, by contract, was initiated. Work on negotiations and consummations of relocation agreements of highways, affected by the reservoir, was completed and the same type work in connection with utilities was practically completed. The acquisition of land was continued, and during the fiscal year 111 tracts were acquired. Maintenance (operating and care) : As the project was under construction during the year, the reservoir was operated and maintained only as a retarding basin. During the floods of January and February 1950, the maximum flood control storage was 9,170 acre-feet and as a result of this storage, it is estimated that crest stages at Delaware, Ohio, and Columbus, Ohio, were reduced 1.7 feet and 0.4 foot, respectively. The total cost was $571,977.60, of which $547,720.53 was for new work and $24,257.07 was for maintenance. The expenditures were $1,145,425.16. Condition at end of fiscal year.-Constructionof the project was initiated in April 1946. The dam and appurtenances were com- pleted in July 1948. The Major item of work remaining to complete construction of the project is the construction of two pump sta- tions at the Waldo, Ohio, levee protection works. This work is being done by contract and is about 19 percent complete. Work on negotiations and consummations of relocation agreements of highways, affected by the reservoir, is complete and the same type work in connection with utilities is about 97 percent com- plete. Of the estimated 376 tracts of land required for the project, 271 tracts have been acquired. The entire project is about 88 percent complete. The total cost to the end of the fiscal year was $7,011,701.03, of which $6,972,414.83 was for new work and $39,- 286.20 was for maintenance. The expenditures were $6,966,444.14.

BIG WALNUT CREEK RESERVOIR, OHIO RIVER BASIN, OHIO Location.-The dam site of the Big Walnut Creek Reservoir is located on Big Walnut Creek, a tributary of Scioto River, Ohio, about 0.35 mile upstream from the village of Central College and about 154 miles above the mouth of the Scioto River. Existing project.-The plan of improvement provides for the construction of a rolled earth-fill dam with a concrete gravity spill- way section controlled by tainter gates, having a maximum height of about 96 feet and a total crest length of approximately 2,620 FLOOD CONTROL-HUNTINGTON, W. VA., DISTRICT 1881 feet. The reservoir created, providing for the storage of 58,900 acre-feet for flood control and 49,500 acre-feet for conservation and water supply for a total of 108,400 acre-feet, will control 190 square miles of the drainage area of Big Walnut Creek, and necessitates the relocation of 14.4 miles of power lines, 10.7 miles of telephone lines, 5.7 miles of gas pipe lines, 1 railroad pump house, and 3 cemeteries containing 733 graves. In addition, it will be necessary to raise, reconstruct, or relocate 21.0 miles of highways. The reservoir will afford substantial protection to the Big Walnut Creek Valley and serve as a unit of the coordinated reservoir system for the protection of the Scioto River and Ohio River Valleys. The reservoir will also provide an assured addi- tional water supply of 35,000,000 gallons per day for the city of Columbus. The existing project was selected for construction under the general authorization for the Ohio River Basin con- tained in'the Flood Control Act approved June 28, 1938. The esti- mated Federal cost of new work, made in 1948, is $3,810,000. In addition to the amount to be expended by the United States, local interests will be required to contribute $5,190,000 making the total first cost of the project $9,000,000. Local cooperation.-The city of Columbus, Ohio, or other local interests are required to furnish funds for the project equal to the difference between the total estimated first cost and the capi- talized flood control benefits. Upon the request of the city of Columbus, the board of directors of the Scioto-Sandusky conserv- ancy district has directed the chief engineer of the district to in- clude in the official plan of the district a multiple-purpose reser- voir on Big Walnut Creek for water supply, flood control and other purposes whereby the Scioto-Sandusky conservancy district will participate with the Federal Government in such project to the extent of approximately $4,878,000 subject to such modifications as may be determined upon a detailed evaluation of the general benefits and a detailed estimate of the cost of the project. In ac- cordance with the Conservancy Act of Ohio, under which the Scioto-Sandusky conservancy district is organized, the district may enter into contracts with the Federal Government for pro- viding flood control works, may purchase, lease or acquire lands, may borrow money, issue bonds and levy assessments against properties located within the district. As the city of Columbus has decided to withdraw from par- ticipation in a multiple-purpose project, the project has been eli- minated from the construction program. Operationsand results during fiscal year.-Costs of $328.35 and expenditures of $377.99 were incurred in the liquidation of out- standing obligations. Condition at end of fiscal year.-This project has been elimi- nated from the construction program due to the decision of the city of Columbus, Ohio, to withdraw from a multiple-purpose project. The total cost of new work to the end of the fiscal year was $110,186.31. The expenditures were $110,186.31: Proposedoperations.--A small portion of the balance unexpend- ed on June 30, 1950 will be applied to the liquidation of outstand- 939127-51-vol. 2---29 1882 REPORT OF CHIEF OF ENGINEERS, U.

ALLEGHENY RIVER, PA.--CONSTRUCTION OF LOCKS: AND DAMS Location,-This river rises in northern Pennsylvania, :flws 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 portion 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. The estimate of cost of new work, revised in 1945, is $18,380,- 000. The current (1950) estimate of annual cost for channel main- tenance is $30,000. The current (1950) estimate of annual cost of operation and care of locks and dams, is $360,000.

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 pipe lines for use in loading and un- loading coal, coke, sand, gravel, limestone, cement, petroleum products, steel products, and other commodities. The transship- ment of freight between river and railroads is handled at private- ly owned river-to-rail terminals. Operationsand results during the fiscal year.-New work: Ne- gotiations were completed with Madison Township officials re- garding a claim for damages to a township road due to flooding in pool 8. Work necessary to final settlement was under way. Maintenance.-Surveys and soundings for dredging as well as snagging operations were performed by hired labor. Hired labor forces dredged a total of 139,024 cubic yards with government plant, as follows: A total of 2,530 cubic yards from approaches to locks 2, 4, 5, 6 and 7; 75,985 cubic yards in the lower approach area to lock 6 by Dredge Harris; and 60,509 cubic yards at Ross Island by dredge Harris. Maintenance (operating and care).-The locks and dams were operated as required and necessary repairs and improvements made thereto and to the operators' quarters and grounds. In addi- tion to ordinary repairs to structures and plant, the following major work was performed by hired labor: at lock 2, the turbine and guard rail fence were repaired; at lock 3, lights were installed on capstans; at lock 4, dwellings were painted; at lock 5, the lower gates were repaired; at lock 6, the upper and lower gates were repaired and flashboards installed on the dam; and at locks 5 and 8, electric wiring was repaired.

TYGART RIVER DAM, W. VA. Location.-The dam site is located on the Tygart River in Tay- lor 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 reservoir 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 structure 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 conservation storage. Low-water control is also provided by storing 100,000 acre-feet during the spring months for release during low rainfall Pleriods to make up the deficiency of water in the Monongahela River. Two pen stocks are contained in the dam for possible future generation of hydroelectric power. The estimated cost of new work, revised in 1940, is $18,500,000. The current (1950) estimate of annual cost for maintenance and operation of the project is $46,000. Operations and results during fiscal year.--New work: Work was completed on reservoir development plans in the reservoir area in cooperation with the State of West Virginia. Maintenance (operating and care).-The reservoir was oper- ated effectively, as required, and necessary repairs made to the dam and related structures. RIVERS AND HARBORS-PITTSBURGH, PA., DISTRICT 1901 From 3 to 4 inches of rain fell over the Monongahela River Basin between the 29th of January and 1st of February 1950, causing a major rise along the Monongahela River. Moderate flood damages were averted during this time through reservoir storage. Minor rises occurred on the 7th of January and on the 25th and 26th of June, during which suspension of navigation was averted for 1 and 11/2 days, respectively, through reservoir storage. Dur- ing periods in August, September, and October, 1949, run-off in the Monongahela Basin was deficient and normal navigation pool stages maintained on the Monongahela River through release of the navigation storage. On February 4, 1950, the reservoir pool rose to elevation 1130.78 or 120.78 feet above minimum pool level. This level represents an impoundment of 185,700 acre-feet of water in storage, the greatest amount since April 1939. Routine operations primarily were made throughout the remainder of the year in accordance with the low-water and storage schedule, ex- cept on the occasion of 13 minor rises when some water was stored and released as river conditions permitted. The total costs were $51,262.70, of which $3.76 was for new work and $51,258.94 for maintenance. The total expenditures were $53,955.69. Condition at end of fiscal year.-The project is fully complete. The reservoir is in operation for low-water control in the Monon- gahela River and for the purpose of flood protection in the Mon- ongahela: and Ohio Valleys. Construction of the dam was started in 1935 and placed in operation in 1938. The total costs of the existing project to the end of the fiscal year were as follows: New work: Regular funds ..................................... $6,431,848.54 Public Works funds .................................. 10,000,000.00 Emergency Relief funds .............................. 1,999,995.00 Total cost, new work .............................. 18,431,843.54 Maintenance, regular funds .............................. 382,789.69 Total cost, all funds ................................ 18,814,633.23 The expenditures were $6,816,565.75 regular funds, $10,000,000 Public Works funds, and $1,999,995 Emergency Relief funds, a total of $18,816,565.75. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950 plus $38,000, appropriated for the fiscal year 1951 will be expended as follows: Accounts payable, June 30, 1950 ........................... $128.07 Maintenance (operating and care): Operations .................. ......................... 29,000.00 Ordinary maintenance and repairs ....................... 8,500.00 "Improvement and reconstruction ........................ 24,709.75 Total, maintenance (operating and care) ................ 62,209.75 Total for all work ................................... 62,337.82 1902 REPORT OF CHIEF OF ENGINEERS, U.

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 Pennsyl- vania 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 13 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 en- largement and improvement of locks and dams 1 to 6 between Pittsburgh and Rices Landing, Pa., by the building of two paral- lel chambers and fixed concrete dams. Locks and dam 1 were eli- minated in 1938 by the raising of the Emsworth Dam, Ohio River. Reconstruction of locks 2 provides for two modernized navigation locks, one 110 by 720 feet and one 56 by 360 feet. 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 is the initial step in the replacement program and will replace locks and dams 10 and RIVERS AND HARBORS-PITTSBURGH, PA., DISTRICT 1903 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 total estimated cost of new work revised in 1950 (exclusive of amounts expended on previous projects) is $65,140,000. This amount is exclusive of $400,000 to be contributed.

RIVERS AND HARBORS-PITTSBURGH, PA., DISTRICT 1905 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. A number of docks and pipe lines are also privately maintained for petroleum and acid products. Marine ways are maintained by some of the larger industries. There are also several terminals for rail-to-river and river-to-rail transfer. Existing private terminals are adequate for shipments and re- ceipt 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 per- cent of traffic using the river passes through the private termi- nals, which are more than adequate for the prospective commerce. Operations and results during fiscal year.-New work: Recon- struction of locks 2: Preliminary work was continued and involved miscellaneous engineering and the preparation of various contract plans and specifications. Construction of the 56 foot lock (river chamber) was continued by contract. The main cofferdam and removal of existing equipment and structures were completed. The foundation for the lock walls was substantially completed. Caisson excavation and placement of concrete were under way and in- volved 55,678 and 53,600 cubic yards, respectively. A total of 18 middle wall and 9 river wall monoliths were completed and con- creting operations under way on 9 middle wall and 6 river wall monoliths. A total of 34,701 cubic yards of concrete was placed in the lock structure. Butterfly valves and frames were installed and various machinery and equipment procured. Installation of the hydraulic, water, air and gas piping systems was under way. Morgantown lock and dam.-Preliminary work was continued and involved miscellaneous engineering work and preparation of various contract plans and specifications. Construction of the lock and dam by contract was continued during the year. In cofferdam 1, construction of the lock was completed. The gates and operating machinery were installed and minor adjustments thereto under way. Backfilling behind the land wall and placement of riprap was also accomplished. Cofferdam 1 was removed and cofferdam 2 built. All concreting operations for the right abutment, dam and piers in cofferdam 2 were completed. Tainter gates and operating machinery were installed and service bridge spans placed from the abutment to pier 4. Cofferdam 2 was removed and construction of cofferdam 3 initiated. Major quantities of work consisted of 25, 575 cubic yards of common and 19,208 cubic yards of rock excavation; placement of 49,000 cubic yards of fill and 9,623 cubic yards of riprap; and placement of 45,333 cubic yards of concrete in the lock walls, dam, and spillway piers. Work was continuedwon the hydraulic, raw water, and com- 1906 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 pressed-air piping systems. Construction of the operations build- ing was well under way. Movement of traffic through the new lock was initiated June 14, 1950. A Contract was awarded for the removal of lock 10. Operations began June 10, 1950, and consisted of the removal of the upper guide wall and clearing of a 20-foot section in the lower approach area. Various contracts were also awarded for operating equipment and machinery. Negotiations were also continued relative to acquisition of land and relocations. Maintenance.-A general survey consisting of field work and the preparation of topographic drawings was continued during the year. Re-establishing control monuments for navigation sur- veys was also continued. Surveys for dredging were made at vari- ous locations from the mouth of the river to pool 8 and plans pre- pared for dredging. A total of 612,645 cubic yards was dredged from the channel at various locations from pool 2 to pool 8 by government plant and hired labor. Of this amount 603,375 cubic yards was removed by the dredge Harris and 9,270 cubic yards by U. S. derrick boat Monallo. In addition, a total of 2,170 cubic yards was dredged from lock chambers and approaches. Maintenance (operating and care).-The locks were operated as required and necessary repairs and improvements made there- to, and to operators' quarters and grounds. Refacing of the lock walls at lock 5 was completed by contract. In addition to ordinary repairs to structures and plant and work performed by, contract, the following work was performed by hired labor: Installation of a visual signal system was under way at locks 2 to 6, inclusive; at lock 3, repairs were made to the turbine and gate operating machinery; upper and lower gates in the river chamber replaced, and repairs made to the gates, valves, sills and other underwater parts in the river chamber; at lock 4, the upper and lower gates in the river chamber and emptying valve in the river wall were replaced, valve, sills and underwater parts in the land chamber repaired, lock walls at expansion joints repaired, water line re- placed and commercial electric current installed; at lock 5, the upper river chamber and lower land chamber gates were removed and leaves repaired; at lock 6, both chambers were unwatered and repairs made to the gates, valves, sills and other underwater parts; at lock 7, replacement of the river wall emptying valve and timber fenders on guard cells was initiated; and at lock 8, a water well was drilled and a water supply system installed.

YOUGHIOGHENY RIVER, PA. Location.-This river, the principal tributary of the Monon- gahela, rises in Preston County, W. Va., near the western boun- dary of Maryland, flows northward through Maryland into Penn- sylvania, thence northwestward to empty into the Monongahela River at McKeesport, Pa. Its length is 123 miles. (See U. S. Geo- logical Survey charts for southwestern Pennsylvania, western Maryland, and northern West Virginia.) Previous projects.-Adopted by River and Harbor Acts ap- proved June 25, 1910,, and January 21. 1927. For further details see page 1274, Annual Report for 1929, and page 1261, Annual Report for 1938. Existing project.--This provides for the canalization of the river from the mouth to West Newton, Pa., 19.3 miles, so as to provide a navigable depth of 9 feet by the construction of two locks and dams. The estimated cost of new work, revised in 1946, is $8,785,000. The current (1950) estimate of annual cost for channel mainte- nance, is $25,000. The existing project was authorized by the River and Harbor Act approved July 3, 1930 (Rivers and Harbors Committee Doc. 9, 61st Cong., 2d sess.). The project was modified by the Chief of Engineers September 7, 1934, to provide for two locks and dams in lieu of three locks and dams previously authorized (no printed report). A map of the river is printed in House Document No. 82, RIVERS AND HARBORS--PITTSBURGH, PA., DISTRICT 1911 Fifty-sixth Congress, first session. The Chief of Engineers is au- thorized to revise the plans and estimates to meet any changes in conditions. Terminal facilities.-Privately maintained terminals for un- loading coal, sand, gravel, manufactured products, etc., ample for present requirements, exist at McKeesport, Pa. Operations and results during fiscal year.-Dredging of the channel between the mouth and Fifteenth Street, McKeesport was initiated by hired labor. A total of 8,300 cubic yards was removed. The total costs were $10,862.56. The expenditures were $13,- 000. Condition at end of fiscal year.-No canalization has been done on the existing project. The effect of pool 2, Monongahela River, permits movement from the mouth to Fifteenth Street, McKees- port, Pa., by commercial tows. The total cost since the adoption of the existing project was $109,681.76, all for maintenance. The total expenditures under the existing project were $111,819.20. Proposed operations.-Thebalance unexpended and accounts re- ceivable on June 30, 1950, amounting to $2,857.49 plus an antici- pated allotment of $12,000 during fiscal year year 1951, will be expended for hired labor maintenance dredging of a 9-foot chan- nel between the mouth and Fifteenth Street, McKeesport, Pa. The additional sum of $25,000 can be profitably expended dur- ing the fiscal year 1952 for scheduled maintenance dredging of the 9-foot channel from the mouth to Fifteenth Street, McKeesport, Pa.

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 earth-fill type with separate uncon- trolled saddle spillway and tunnel outlet works. The dam is 1,050 feet long at the top, rises 154 feet above the stream bed, 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 remaining 7,800 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 Act approved June 22, 1936 and June 28, 1938. The estimated cost of new work, revised in 1950, is $5,300,000. 'The current (1950) estimate of annual cost for maintenance and operation of the project is $61,- 000. Local cooperation.-Section 2 of Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work: Prelimi- nary work was continued throughout the year and consisted of plans and specifications for bulkheads and hoisting rig and the preparation of a master land use plan. Construction of a one- story public sanitary building with appurtenances was started by contract on July 11, 1949, and completed October 26, 1949. A contract for furnishing and the installation of bulkheads and hoisting rig was awarded June 12, 1950. Maintenance (operating and care).-The reservoir was operat- ed for the benefit of flood control, as required, and necessary re- pairs made to the dam and to the operators' quarters and grounds throughout the year. In connection with reservoir management ac- tivities, work consisted of maintaining public use areas. Heavy rain and melting snow over the upper Allegheny River Basin March 26 and 27, 1950, caused flooding along the Allegheny River at and above Franklin, Pa. The water retained in the reser- voir during this time averted moderate flood damages between Tionesta, Pa., and Franklin, Pa. Routine operations were per- formed during the remainder of the year, except on the occasion of nine minor rises, when some water was stored and released as river conditions permitted. The highest level reached by the reservoir pool during the year was elevation 1135.07 on March 31, 1950, when 58,800 acre-feet of water was in storage. The total costs were $106,562.81, of which $59,921.03 was for new work and $46,641.78 for maintenance. The total expendi- tures were $103,827.28. FLOOD CONTROL-PITSBURGH, PA., DISTRICT 1919 Condition at end of fiscal year.-The dam is 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 flowage easements over 349 acres. A master land-use plan is complete. Work remaining to be done consists of preliminary work including preparation of plans and specifications for public use facilities and as-built drawings; in- stallation of bulkheads and hoisting rig at the control structure by contract; and construction of public use facilities by contract. The total costs to the end of the fiscal year were as follows: Regular funds: New work ....................................... $5,170,380.51 Maintenance ........................................ 229,520.74 Total ........................................... 5,399,901.25 Emergency Relief funds: New work .................. 24,201.10 Total costs, all funds .............................. 5,424,102.35 The total expenditures were $5,412,933.16, of which $5,388,- 732.06 was from regular funds and $24,201.10 from Emergency Relief funds.

BERLIN RESERVOIR, OHIO RIVER BASIN, OHIO Location.-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 reser- voir dam with a partially controlled, concrete, gravity center spill- way flanked by rolled-fill abutment sections joining the valley sides. The dam is 5,750 feet long at the top, rises 101.5 feet above the stream bed, 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 permanent 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 construction under the general authorization for the Ohio River Basin contained in the Flood Control Act approved June 28, 1938. 3'"-- 5--v . -- 33 1946 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The estimated cost of new work, revised in 1950, is $6,381,000. The current (1950) estimate of annual cost for maintenance and operation of the project is $60,000. Local cooperation.-Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work: Pre- liminary work was in progress and involved the preparation of plans and specifications, completion of a master land use plan and miscellaneous engineering. Negotiations were continued in regard to concluding land acquisition and settlements with owning agencies for two remaining utility alterations. Negotiations were also in progress with the Mahoning Valley Sanitary District rela- tive to a contract for obtaining water from the reservoir. Land- scaping and work on miscellaneous appurtenances to the dam were performed. The damtenders' dwellings were completed during the year by contract. Drilling of a water well for the public sanitary building was started June 26, 1950, by contract. Contract operations for paving parking areas and approach roads were started May 24, 1950. Maintenance (operating and care).-The reservoir was oper- ated effectively for low-water regulation, as required, and nec- essary repairs were made to the operators' temporary quarters and grounds throughout the fiscal year. In connection with reser- voir management activities, work consisted of maintaining public use facilities. Heavy rains from February 12 to February 14, 1950, over the Mahoning River Basin, amounting to 3.5 inches, caused a major rise along the Mahoning River. The water retained in this reser- voir reduced flood damages at Warren, Ohio, and in conjunction with Mosquito Creek Reservoir averted moderate flood damages below Niles, Ohio. Water stored from June 24 to June 26, 1950, from heavy rain over the reservoir basin, averted nuisance flood- ing along the upper Mahoning River. Routine operations were made the remainder of the year in accordance with the low-water schedule for maintaining satisfactory flows at Leavittsburg and Youngstown, Ohio, except on the occasion of five minor rises when some flood storage water was retained and released as river con- ditions permitted. The highest level reached by the reservoir pool during the year was elevation 1,028.84 on June 27, 1950, when 75,200 acre-feet of water was in storage. The total costs were $151,382.84, of which $101,847.12 was for new work and $49,535.72 for maintenance. The total expenditures were $148,387.24. 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 is complete except for settlement with the owning agencies for two utility alterations. The acquisition of land and related work are complete except for disposition of cases in condemnation. The total acreage in- volved has been acquired and consists of 6,935.10 acres in fee FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1947 simple and flowage easements over 1,054.76 acres.

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, Ohio, and Kinsman, Ohio, and Pennsylvania.) Existing project.--This provides for the construction of a reser- voir dam of the rolled earth-fill type with outlet facilities through the dam, and an uncontrolled natural wasteway to discharge over- flow 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 discharged 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 regulation and flood-control purposes in Mahoning and Beaver Valleys below. A modicum of effect ap- plies 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 reservoir is operated for flood-prevention purposes as a unit of a coordinated reservoir system. The project was selected for construction under the general authorization for the Ohio River Basin contained in the Flood Control Act ap- proved June 28, 1938. The estimated cost of new work, revised in 1950, is $4,495,000. The current (1950) estimate of annual cost for maintenance and operation of the project is $39,000. Local cooperation.-Section 2 of the Flood Control Act ap- proved June 28, 1938, applies. Operations and results during fiscal year.-New work: Pre- liminary work involving plans and specifications, master land use plan and miscellaneous engineering work was performed during the year. Negotiations were underway with officials of the city of Warren, Ohio, in regard to leasing Government-owned land FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1949 near the, dam for a pumping station site. Negotiations were also under way to effect conclusion of work relative to land acquisition and making settlement with the owning agency for the remaining utility alteration. Landscaping operations were continued. Monu- menting of reservoir lands and modifications of the channel at the outlet works were completed. Construction of a service bridge to the control tower was com- pleted by contract May 9, 1950. Paving of the entrance road to the dwellings was started October 26, 1949, and completed May 15, 1950, by contract. Drilling of a water well for the public sanitary building was started May 9, 1950, and completed June 17, 1950, by contract. Construction of the damtenders' dwellings and storage building was completed by contract during the year. A contract was awarded June 5, 1950, for construction of a public sanitary building. A contract was also awarded on June 8, 1950, for paving parking areas and approach roads. Maintenance (operating and care).-The reservoir was oper- ated effectively for low-water regulation, as required, and nec- essary repairs made to the grounds and plant. Repairs were made to the gates and valves. In connection with reservoir man- agement activities, work consisted of maintaining public use fa- cilities. Heavy rains on February 12, 13 and 14, 1950, over the Mahoning River Basin caused a major rise along the Mahoning River. The water retained in this reservoir in conjunction with Berlin Reser- voir averted moderate damages below Niles, Ohio. Routine opera- tions in accordance with the low-water schedule for maintaining satisfactory flows at Youngstown were made throughout the re- mainder of the year except on occasion of nine minor rises when some flood storage water was retained and released as river con- ditions permitted. The. highest level reached by the reservoir pool during the year was elevation 902.28 on May 1, 1950, when 89,400 acre-feet of water was in storage. The total costs were $203,374.53, of which $167,441.20 was for new work and $35,933.33 for maintenance. The total expenditures were $209,096.08. Condition at end of fiscal year.-The dam is complete and is in operation for flood control and low-water regulation purposes in the industrialized Mahoning and Beaver Valleys, below. Con- struction of the dam was started in July 1943 and was ready for beneficial use in January 1944. All work relative to relocations is complete except for settlement with the owning agency for one remaining utility. The acquisition of land and related work are complete except for disposition of cases in condemnation. The total acreage involved has been acquired and consists of 11,213.98 acres in fee simple and flowage easements over 275.21 acres. The monumenting of reservoir lands is complete. A master land use plan is substantially complete. The State of Ohio has a license from the Secretary of the Army for development of recreation sites in the reservoir area. However, no sites were developed by the end of the year. The damtenders' dwellings and storage build- ing are complete. Construction for the public sanitary building is 12 percent complete. Landscaping of the project is approximately 1950 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 90 percent complete. Work remaining to be done consists of the following: concluding preliminary work; conclusion of land ac- quisition; effect settlement for remaining utility alteration; com- plete construction of a public sanitary building by contract; and complete paving parking areas and approach roads by contract. The total costs to the end of the fiscal year, all from regular funds, were $4,090,604.59 of which $3,978,231.90 was for new work and $112,372.69 for maintenance. The total expenditures were $4,082,844.43. Proposed operations.-The balance, unexpended and accounts receivable on June 30, 1950, plus an anticipated allotment of $28,000 for maintenance during the fiscal year 1951, will be ap- plied as follows: Accounts payable, June 30, 1950 ........................... $9,468.67 New work: Complete preliminary work ................. $2,999.20 Complete landscaping ........................ 1,227.50 Construction of a public sanitary building by contract .................................. 28,839.47 Paving parking area and approach roads by contract .................................. 21,575.30 Complete work relative to land and damages 486.63 Complete remaining utility settlement with own- ing agency by agreement ................... 2,040.00 Total, new work .................................... 57,168.10 Maintenance (operating and care) : Operation .................................. $21,700.00 Ordinary maintenance and repairs ........... 7,500.00 Improvement and reconstruction ............. 3,527.31 Total, maintenance (operating and care) .. ,........ 32,727.31 Total for all work .................................. 99,364.08 The above expenditures for new work will complete construc- tion of the project.

FLOOD CONTROL-PITTSBURGH, PA., DISTRICT 1955 Local cooperation.-See page, 8 for requirements. The local protection projects for Buckhannon, W. Va., and Wilcox, Pa., have been deferred due to the inability of local interests to furnish assurances of local cooperation prescribed by law. In accordance with section 3 of the act of Congress, approved December 22', 1944 (Public Law 534, 78th Cong.), local interests were formally noti- fied of the required conditions of local cooperation and of the 5-year period within which assurances must be furnished. Officials of the city of Buckhannon were notified February 21, 1946, and acknowledgement made June 22, 1946. The commissioners of Elk County and supervisors of Jones Township were notified ac- cordingly March 6, 1950, in regard to the project for Wilcox, Pa. Acknowledgement was made by the commissioners of Elk County March 10, 1950. Operations and results during fiscal year.-Operations during the year consisted of surveys, investigations, studies, preparation of detailed plans, and preparation of construction plans and spe- cifications for the development of the general comprehensive plan for flood control in the Ohio River Basin. The costs during the year were $55,726.82. The expenditures were $57,440.59. Condition at end of fiscal year.-The preparation of project plans and of construction plans and specifications was well ad- vanced. The status of projects selected for construction under this authorization is given in individual reports. The total costs to the end of the fiscal year were $838,541.83, of which $821,815.88 was for regular funds and $16,725.95 from Emergency Relief funds. The total expenditures were $835,- 275.90, of which $818,549.95 was from regular funds and $16,- 725.95 from Emergency Relief funds. Proposed operations.-The balance unexpended and accounts receivable on June 30, 1950, a total of $253,823.92, will be applied to accounts payable and to the preparation of project plans and construction plans and specifications for the development of the general comprehensive plan. The additional sum of $263,400 can be profitably expended during fiscal year 1952 for preparation of detailed plans and con- struction plans and specifications.

Location.--The harbor is located on the south shore of Isle Royale, 55 miles northerly from the upper entrance to Keweenaw Waterway, Michigan, and 185 miles northeasterly from Duluth, Minn. (See U. S. Lake Survey Chart No. 981.) Existing project.-This provides for an entrance channel 75 feet wide and 14 feet deep, connecting the outer and inner harbors. 1961 939127--51--vo. 2---34 1962 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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. The estimated cost for new work, made in 1948, is $72,500. An- nual maintenance is not required. The existing project was authorized by the River and Harbor Act approved March 2, 1945. (See H. Doc. 446, 78th Cong., 2d sess.) Local cooperation.-None required. Terminal facilities.-There are two small privately owned fish- ing wharves. Operations and results during fiscal year.-Advance planning for the construction of the project was done at a cost and expen- diture of $72.11 for new work. Condition at end of fiscal year.-No work has been done on the construction of the existing project. A controlling depth of 6 feet for a width of 50 feet exists in the entrance channel. The total cost was $1,304.25, all for new work. The total expenditures were $1,304.25. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $695.75 will be applied to advance planning for new work by hired labor. No work is scheduled during the fiscal year 1952.

GRAND MARAIS HARBOR, MINN. Location.-The harbor is suituated on the north shore of Lake Superior, 106 miles northeasterly from Duluth, Minn. (See U. S. Lake Survey Chart No. 9.) Existing project.-This provides for rock-filled timber crib breakwater piers 350 feet in length from the east and west points RIVERS AND HARBORS-DULUTH, MINN., DISTRICT 1963 of the bay to narrow the entrance; for constructing concrete sea walls across the ledge at the southeast corner of the harbor; and 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 providing 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 rubble mound 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 varia- tion 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 condi- tions, of about 1 foot above or below the mean lake level prevail- ing at the time. The estimate of cost for new work, revised in 1950, was $359,,- 000. The latest (1950) approved estimate of cost for annual main- tenance is $8,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1879 Breakwaters and dredging of anchorage area of 26 H. Ex.

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. 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.-Maintenance sur- veys were made at a cost and expenditure of $973.24. 1964 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Conditionat 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 be- tween 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 sea walls are in excellent condition. The break- waters are in good condition. 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 $209,819.91 for new work and $126,273.91 for mainte- nance, a total of $336,093.82. The total expenditures were $336,- 093.82. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $687.69 will be applied to maintenance surveys and inspections by Government plant and hired labor during the fiscal year. No work is proposed for fiscal year 1952.

TWO HARBORS (AGATE BAY), MINN. Location.-The harbor is situated on the north shore of Lake Superior, 27 miles northeasterly from Duluth, Minn. (See U. S. Lake Survey Chart No. 96.) Existing project.-This provides for narrowing the natural en- trance by the construction of two breakwaters, 1,625 feet and 900 feet long, from the eastern and western points of the bay, respec- tively; and for dredging a maneuvering area on the north side of the harbor to depths of 26 and 28 feet, referred to low-water datum for Lake Superior, which is taken at 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 na- ture, due to wind and barometric conditions, of about 1 foot above or below the mean lake level prevailing at the time.

Local cooperation.-None required. Terminal facilities.-The six coal docks, three general merchan- dise wharves, and several minor wharves, all privately owned, are served by improvements made along Keweenaw Waterway. The city of Hancock has two publicly owned wharves. The village of Houghton has wharf improvements at the ends of three streets. The facilities are considered adequate for existing commerce. Operations and results during the fiscal year.-New work: Modification of the breakwater pierheads was completed with Government plant and hired labor at a cost of $17,422.09. The expenditures were $14,640.73. Maintenance: Maintenance dredging was done with U. S. dipper dredge Gaillard and a total of 15,471 cubic yards were removed from the upper entrance and canal. Baffle walls were constructed and banks graded to stablize material behind revet- ments and 1,143 tons of stone were placed as repairs to upper entrance breakwaters, all by U. S. derrick boat Coleman. The costs of the various items of work were as follows: $11,760.66 for dredging; $16,329.79 for breakwaters; $10,595.78 for revetments; and $10,740.67 for inspections, surveys and water- way patrol; a total of $49,426.90. The expenditures were $32,- 827.50. The total costs, all work, were $66,848.99 and the total ex- penditures were $47,468.23. Condition at end of fiscal year.-The existing project is 75 per- cent complete. The breakwaters are in good condition except for a weakness occurring 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 remaining timber revetments along the waterway 1980 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 are in poor condition. The mooring pier at the Lily Pond requires repairs to halt movement, and permit dredging to project depth adjacent thereto, and that at the Portage River harbor of refuge is in good condition. Annual redredging of channels will be re- quired indefinitely. The controlling depth on June 30, 1950, 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. For work performed with regular funds, the costs of the exist- ing project were $5,772,115.36 for new work and $3,018,116.27 for maintenance, a total of $8,790,231.63.

Location.-This harbor is on the north shore of Lake Michigan, about 135 miles northeasterly from Green Bay Harbor and 220 miles northerly from Milwaukee. (See U. S. Lake Survey Chart No. 701.) Previous projects.-Adopted by River and Harbor Act of June 14, 1880. For further details see page 1933 of Annual Report for 1915 and page 1422 of Annual Report for 1938. Existing project.-This provides for two breakwaters extend- ing from the shore on either side of the mouth of the Manistique River, 1,744 feet and 1,480 feet in length for the east and west breakwaters, respectively, and for a pier 375 feet long on the west side at the river mouth. It further provides for a channel through the outer basin, 19 feet deep from that depth in the lake to a point about 300 feet inside the entrance, thence 18 feet to a point about 1,150 feet upstream from the mouth of the river, and thence 18 feet, except where rock is encountered at less depth, for a further distance of about 500 feet, with widths of 276 feet at the breakwater entrance, increasing to 475 feet through the outer basiri, decreasing to 215 feet at the river mouth, thence varying from 180 feet to 325 feet at the upper limit; the total length of channel being about 4,100 feet. The breakwaters are formed of stone-filled piling and timber cribs, capped with concrete super- structure; the west pier is formed of stone-filled plank cribs. 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 about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work, revised in 1950, was $651,- 800, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $30,500. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1905 Breakwaters and outer harbor.. _ __ H. Doe. 429, 58th Cong., 2d sess.

H. Doc. 721, 80th Cong., 2d sess. 1 Contains latest published map. Local cooperation.-The act of May 17, 1950, provided that responsible local agencies shall furnish assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from damage due to the construction work and RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 1999 the subsequent maintenance thereof. All prior requirements have been complied with. Terminal facilities.-Besides a car-ferry slip there are two coal and building material wharves, two fishing wharves, and numer- ous lumberyard slips. While these facilities are considered fairly adequate for existing commerce, it is believed that a wharf, with rail connection and under public control, should be provided. Operations and results during fiscal year.-Operationsconsisted of dredging 9,559 cubic yards of material for restoration of proj- ect depth at a cost of $10,762.54. Soundings were taken at a cost of $1,500.16. Plans and specifications for future pier repairs were made at a deferred cost of $1,212.19. All work was done by hired labor and use of Government plant. The total cost was $12,262.70 for maintenance. The total net expenditures were $19,191:66. Condition at end of fiscal year.-The project in effect prior to the modification of May 17, 1950, was completed in 1917. No work has been done on the last modification of the project provid- ing for present dimensions of channel. The construction of the breakwaters inclosing the basin was commenced in May 1911 and completed in November 1914. Construction of the plank-crib pier was commenced in May 1909 and completed in October 1909. Dredging of the channel to 18 feet over practically all the area below the carferry slip was commenced in June 1915 and com- pleted in July 1915. Dredging of the channel above the slip to ledge rock was commenced in July 1917 and completed in August 1917. The breakwaters are in generally good condition. The plank-crib pier is in a very dilapidated condition and should be rebuilt. The controlling depths at low-water datum at the close of the fiscal year were 17.2 feet in the channel through the outer basin to the river mouth, thence 15.3 feet in the river to about 500 feet above the car ferry slip, decreasing to about 15 feet over a width of about 90 feet along the west revetment to the coal wharf. The costs under the existing project were $307,252.18 for new work and $250,355.49 for maintenance, a total of $557,- 607.67. The total expenditures were $559,090.82. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $87.41, plus accounts receivable of $380.65, plus an anticipated allotment of $22,500 during fiscal year 1951, a total of $22,968.06 will be applied as follows: Accounts payable June 30, 1950 ............................. $109.69 Maintenance: Operation of U.

MENOMINEE HARBOR AND RIVER, MICH. AND WIS. Location.-On the west shore of Green Bay, distant about 49 miles northeasterly from Green Bay Harbor, and about 155 miles from Milwaukee via Sturgeon Bay Canal. (See U. S. Lake Survey Chart No. 723.) Previous projects.-Priorto 1902 the harbor and river consti- tuted two works. Harbor: River and Harbor Acts of March 3, 1871, September 19, 1890, and March 3, 1899. River: River and Harbor Acts of September 19, 1890, July 13, 1892, and June 3, 1896. For further details see page 1933 of Annual Report for 1915 and page 1424 of Annual Report for 1938. 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 and 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 of 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 turn- ing basin 21 feet deep on 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 dis- tance 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 pressures, of about 11/2 feet above or below the mean lake level prevailing at the time.

Terminal facilities.-Besides a car-ferry slip, there are numer- ous wharves for handling coal, building materials, and miscella- neous commodities. The city of Marinette has provided a public wharf. The facilities are considered fairly adequate for existing commerce, except that there is need for a public wharf owned by the city of Menominee with warehouse and railway connection. Operationsand results during fiscal year.-Operationsconsisted of taking soundings at a cost of $3,067.15. Soundings taken dur- ing the previous fiscal year involved a cost of $3,234.86. All work was done by hired labor and use of Government plant. The total cost was $6,302.01 for maintenance. The total net expenditures were $3,893.33. Condition at end of fiscal year.-The project in effect prior to the modification of March 2, 1945, was completed in 1938. No work will be necessary at the present time, 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 is now available. The en- trance piers were completed in 1884 and are in generally good con- dition. 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 only for a length of about 1,216 feet. The controlling depths at low-water datum at the close of the fiscal year were 21 feet in the channel to the Marinette municipal wharf and in the turning basin, except in the southerly 125 feet of the basin, where it shoals to about 9 feet along the extreme southerly limit. The channel above the municipal wharf has depths of 12 feet or more for a distance of 2,500 feet to the vicinity of the Marinette Yacht Club. The river is available for rafting and logging for 2002 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 about 102 miles above its mouth. The costs and expenditures under the existing project were $149,504.49 for new work and $526,137.68 for maintenance, a total of $675,642.17. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $134.61, plus an anticipated allotment of $13,000 during fiscal year 1951, a total of $13,134.61 will be applied to maintenance dredging by U. S. dipper dredge Kewaunee about October 1950. Dredging is required for maintenance of project dimensions of channel. Minor repairs are necessary to the concrete superstruc- ture on the north pier. The additional sum of $3,000 can be profit- ably expended during the fiscal year 1952 for soundings and sur- veys.

Local cooperation.-None required. Terminal facilities.-The wharf and landing facilities are in general adequate for the accommodation of existing commerce. Operations and results during fiscal year.-Maintenance: Op- erations consisted of removing stone obstructions from channel above De Pere lock; dredging a total of 38,164 cubic yards of material for restoration of project depth, as follows: 1,150 cubic yards below and above Little Chute Combined locks, 14,914 cubic yards below Menasha lock, 18,380 cubic yards in Boom Cut on Wolf River, 3,720 cubic yards at Calumet Harbor on Lake Winne- bago; and soundings were taken below Menasha lock, at Stock- bridge, Brothertown, and Calumet Harbors on Lake Winnebago, and in Boom Cut on Wolf River, at a total cost of $27,586.43 for maintenance. Operating and care: Operations consisted of making necessary repairs to locks, dams, canal banks, and lock houses, including cleaning and painting all sluice gates in Little Kaukauna dam and one sluice gate in Kaukauna dam; replacing all decayed or dam- aged planking, wall backing, miter sill and valve platform timbers and gate timbers, providing concrete hollow quoins and steel and concrete lower miter sill, relaying dry wall, removing and replac- ing backfill for lock walls and placing drain tile in fill behind lock walls, rebuilding all tripod platforms in concrete and providing concrete cap on lock walls, installing steel valves and frames in lower lock gates and steel valves and frames in timber valve plat- form, and overhauling all gates, upper valves, valve operating gear and gate operating mechanisms at Kaukauna Fifth lock; re- placing steel valves and frames in lower gates and overhauling valve operating mechanisms at Kaukauna Second lock; over- hauling valves and valve operating mechanisms at Little Chute Second lock- and installing roller conveyor for portaging of row- boats around the lock at Grand River lock, at a cost of $143,522.98. The locks and dams were operated in accordance with the existing project and gages were read at a cost of $170,535.25. All work was done by hired labor and use of Government plant. The total cost of operating and care was $314,058.23. The total cost of all work was $341,644.66. The total net expenditures were $347,- 298.68. 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 origi- nal depths generally about 2 feet. The controlling depths at stand- ard low water at the close of the fiscal year were as follows: 2014 REPORT OF CHIEF OF ENGINEERS, U. S.

The head of navigation for boat traffic is New London on the Wolf River and Portage on the upper Fox, except that during high water on the Wisconsin River boats can proceed from Portage to the Mississippi River. The work remaining to be done to com- plete the project is dredging in the upper Fox River and the upper portion of the Wolf River; also rock removal and deepening Neenah Channel on lower Fox River. Deepening Neenah Channel is no longer desired by navigation interests. The remaining rock removal is not needed unless there is a material increase in com- merce. Additional dredging on the upper river is no longer con- sidered necessary and is not justifiable from an economic stand- point. Except for Menasha lock, which should be rebuilt, the existing locks and dams are in generally fair to good condition. The costs under the existing project were $871,724.01 for new work and $4,927,633.07 for maintenance, including $2,374,820.51 for operating and care, a total of $5,799,357.08. The total expendi- tures were $5,826,897.57. In addition, the sum of $3,795,495.53 (including $89,309.40 under previous projects) was expended be- tween July 5, 1884, and June 30, 1935, on the operating and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $29,185.88 plus accounts receivable of $13,138.77, plus an anticipated allotment of $285,000 during fiscal year 1951, a total of $327,324.65 will be applied as follows: Accounts payable June 30, 1950 ............................. $1,102.27 Maintenance: Dredging by U.

Location.-In the entrance to Green Bay, a westerly arm of Lake Michigan, distant about 4 miles northeasterly from the north end of the peninsula which separates Green Bay from Lake Michi- gan and about 30 miles southeasterly from Escanaba, Mich. (See U. S. Lake Survey Chart No. 702.) Existing project.---his provides for an entrance channel at Detroit Harbor, located on the south side of Washington Island, 150 feet wide and 14 feet deep at low-water datum from that depth in Green Bay to a turning basin of the same depth, 400 feet long and 150 to 300 feet wide, near the inner end of Detroit Island, a distance of about 3,700 feet; and for an entrance channel at Jack- son Harbor, located on the north side of Washington Island, 150 feet wide and 12 feet deep at low-water datum through the en- trance bar, a distance of about 500 feet. 2016 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 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 1948, is $109,- 800. The latest (1937) approved estimate for annual costl of maintenance is $2,300 ($1,500 for Detroit Harbor and $800 for Jackson Harbor). The existing project was authorized by the River and Harbor Act of August 26, 1937 (H. Doc. 90, 75th Cong., 1st sess.). The latest published map is in the project document. Local cooperation.-None required. Terminal facilities.--At Detroit Harbor there is a ferry dock, several fishing wharves, and a marine railway. At Jackson Harbor there are several fishing wharves and a landing for small craft. These facilities are considered adequate for existing commerce. Operationsand results during fiscal year.-Operations consisted of taking soundings at Detroit Harbor and Jackson Harbor, by hired labor and use of Government plant at a cost of $809.15 for maintenance. The total net expenditures were $809.15. Condition at end of fiscal year.-The existing project is about 92 percent complete. The work remaining to be done is removal of rock from Jackson Harbor to provide project depth of 12,feet, which is not considered necessary under present conditions. Dredg- ing of the channel and turning basin at Detroit Harbor arid the channel to ledge rock at Jackson Harbor was commenced i No- vember 1938 and completed in October 1939. The controlling depths at low-water datum at the close of the fiscal year wre 14 feet in the entrance channel and turning basin at Detroit Harbor and 9.6 feet over a width of 100 feet on the westerly side of en- trance channel at Jackson Harbor, thence decreasing to adepth of 4 feet along the easterly edge. The costs and expenditures inder the existing project were $62,838.06 for new work and $1,143.02 for maintenance, a total of $63,981.08. Proposed operations.--No work is scheduled for fiscal years 1951 and 1952.

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 irevetted' canal, thence 250 feet through Sturgeon Bay to a point 5,400 feet northwest 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, south- easterly 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. 2018 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work, revised in 1945, was $736,- 300, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $120,000.

These facilities consist of four coal wharves, four ship- building yards, and one package-freight wharf. The city of Stur- geon Bay has provided a public wharf. There is also an inactive large stone wharf located about 5 miles northwesterly from the city of Sturgeon Bay. Operationsand results during fiscal year.-Operationsconsisted of dredging 6,420 cubic yards of material for restoration of project depth at a cost of $5,621.79. Soundings were taken at a cost of $4,420.98. Soundings, sweeping and rock removal, done during the previous fiscal year, involved a cost of $5,863.76. Re- construction of 301 linear feet of the north revetment and 224 linear feet of the south revetment, by contract, with steel sheet piling, cost $100,746.28. Preliminary plans were made for install- ing a traffic control system at a deferred cost of $222.91. All work, except reconstructing a portion of the north and south re- vetments, was done by hired labor and use of Government plant. The total cost was $116,652.81 for maintenance. The total net expenditures were $101,943.66. 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 RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2019 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 generally good condition. The canal revetments require repairs and back- filling. The controlling depths at low-water datum at the close of the fiscal year were 22 feet in the canal and 20 feet in the turning basin. The costs under the existing project were $736,- 303 for new work and $1,516,861.68 for maintenance, a total of $2,253,164.68. The total expenditures were $2,246,446.81. 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 improve- ment under the provision of the permanent indefinite appropria- tions for such purposes. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $90,922.44, plus accounts receivable of $3,777.32, plus an anticipated allotment of $32,000 during fiscal year 1951, a total of $126,699.76 will be applied as follows: Accounts payable June 30, 1950 ............................ $10,718.10 Maintenance: Operation of U.

ALGOMA HARBOR, WIS. Location.-Algoma Harbor is on the west shore of Lake Michi- gan, distant about 68 miles from Green Bay via Sturgeon Bay Canal and about 115 miles northerly from Milwaukee. (See U. S. Lake Survey Chart No. 703.) Previous projects.-Adopted by the River and Harbor Act of March 3, 1871, and modified by River and Harbor Acts of March 3, 1873; March 3, 1875; July 5, 1884; and March 3, 1899. For further details see page 1935 of Annual Report for 1915 and page 1445, Annual Report for 1938. Existing project.-This provides for an outer harbor 14 feet deep enclosed by a north pier, 1,102 feet long, extending approxi- mately normal to the shore, and a south breakwater, 1,530 feet long, extending from the shore at a point about 1,000 feet south of the remaining 481 feet of the pier on the south side of the channel at the mouth of Ahnapee River, and for a channel of same depth as outer harbor, except where rock is encountered at less depth, extending from that depth in the lake up the river a distance of 1,000 feet from its mouth, a total length of about 2,100 feet; this channel varies in width from 175 to 80 feet at Second Street Bridge. The piers are formed of stone-filled timber cribs and pil- ing and the breakwater of stone-filled timber cribs, concrete cais- sons, and piling. The north pier and south breakwater have 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 about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work, made in 1907, was $140,000, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $13,000.

Local cooperation.-None required. Terminal facilities.-These consist of a coal wharf and several fishing wharves. The facilities are considered adequate for existing commerce. Operations and results during fiscal year.-Operationsconsisted of placing 894 tons of stone as riprap along the north pier at a cost of $6,404.98. Soundings were taken at a cost of $332.52: Borings were taken and test piles driven for future repairs of the south pier at a deferred cost of $700.86. All work was done by hired labor and use of Government plant. The total cost was $6,737.50 for maintenance. The total net expenditures were $6,737.50. Condition at end of fiscal year.-The existing project was com- pleted in 1909. The north pier was completed in 1890, the south pier and breakwater and dredging in 1909. The north pier arid south breakwater are in generally good condition. The south stub pier at the river mouth is in a dilapidated condition and should be rebuilt. The controlling depths at low-water datum at the close of the fiscal year were 14 feet in the entrance channel to the outer end of south stub pier, decreasing to 12 feet to the coal wharf at the inner end of the north pier, thence 9 feet in a narrow channel to Second Street Bridge. The Ahnapee River is navigable for a distance of about 2 miles from its mouth for vessels drawing not more than 4 feet. The costs under the existing project were $99,- 236.15 for new work and $261,230.87 for maintenance, a total of $360,467.02. The total expenditures were $361,167.88. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $930.34 will be applied to sounding harbor, care and supervision during the fiscal year.

The harbor is at the mouth of the Kewaunee River. (See U. S. 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 turning 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 breakwater 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 about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work, revised in 1948, is $936,000. exclusive of amount expended on previous projects. The latest (1948) approved estimate of annual cost of maintenance is $20,000.

Soundings were taken at a cost of $973.00. Dredging done during the previous fiscal year involved a cost of $389.51 and reconstruction of 216 linear feet of the south pier done during the previous fiscal year involved a cost of $5,- 225.46. All work was done by hired labor and use of Government plant. The total cost was $21,560.30 for maintenance. The total net expenditures were $23,846.31. Condition at end of fiscal year.-The existing project is about 71 percent complete. The work remaining to be done 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 condi- tion except that the south pier requires repairs. Construction 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 en- trance channel and interior basin, to existing project depth, was commenced in April 1938 and completed in October 1938. The con- trolling depth at low-water datum at the close of the fiscal year was 20 feet in the entrance channel between the piers and over an area 500 by 500 feet in the turning basin.

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 chan- nel 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 shore line on the north side of the channel. The piers are formed of stone-filled timber cribs and piling, and have been provided with concrete superstructure; 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 about 1 / feet above or below the mean lake level prevailing at the time.

Soundings were taken at a cost of $953.27. Dredging done during the previous fiscal year involved a cost of $301.00. All work was done by hired labor and use of Government plant. The total cost was $26,610.43 for main- tenance. The total net expenditures were $27,070.17. Condition at end of fiscal year.-The existing project is about 88 percent complete. The work remaining to be done consists of dredging a 10-foot width along each side of the lakeward portion of the entrance channel between the piers. This dredging was necessarily omitted to avoid removal of riprap along the entrance piers and thereby endangering them. The present width of chan- nel is considered adequate for present and reasonably prospective commerce. The south pier, completed in 1883, and the north pier in 1908, are in generally good condition. Dredging of the entrance channel and inner basin tp existing project depth, was commenced in March 1937 and substantially completed in May 1937. The con- trolling depths at low-water datum at the close of the fiscal year were 18 feet in the channel between the piers and 17 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:draw- ing not more than 4 feet. The costs under the existing project were $74,721.66 for new work and $603,170.42 for maintenance, a total of $677,892.08. The total expenditures were $678,336.02.

MANITOWOC HARBOR, WIS. Location.-This harbor is on the west shore of Lake Michigan, distant about 79 miles northerly from Milwaukee and about 106 miles from Green Bay via Sturgeon Bay Canal. (See U. S. 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 chan- nel 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 railway 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 inter- mediate reductions and enlargements; for removal of old north stub pier at the river entrance; and for dredging in the outer har- bor an approach channel 21 feet deep to a proposed city terminal on the lake front south of the shore end of the south breakwater. The breakwaters are formed of stone-filled timber cribs, concrete caissons, and piling, all of which are capped with concrete super- structures. 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 bartmetric pressure, RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2027 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 1948, is $653,000, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $30,000.

Aug. 26, 1937 Channel in the river_____________________________ Rivers and Harbors Committee Doc. 80, 74th Cong., 2d sess. (Contains latest published map.) Local cooperation.-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 Sec- retary of War that such terminal will be constructed." The plan for the municipal terminal has been abandoned. All other require- ments have been complied with. Terminal facilities.-Besides three car-ferry slips there are two grain elevators, two 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 suit- able wharf with warehouse and railway connection, which should be open to the general public. Operationsand results during fiscal year.-Operationsconsisted of dredging 33,860 cubic yards of material for restoration of project depth at a cost of $24,773.05. Soundings were taken at a cost of $1,206.22. Placing 1,327 tons of stone as riprap along the breakwaters cost $4,512.24. All work was done by hired labor and use of Government plant. The total cost was $30,491.51 for maintenance. The total net expenditures were $30,683.73. 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. 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. Dredg- ing of the river channel was commenced in June 1939 and com- pleted in July 1942. The controlling depth at low-water datum at the close of the fiscal year was 21 feet in the channel through the outer basin and in the river to the second railway bridge. The 2028 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 costs under the existing project were $436,752.02 for new work and $711,147.01 for maintenance, a total of $1,147,899.03.

Soundings were taken at a cost of $681.93. Placing 952 tons of stone as riprap along the north breakwater cost $6,805.59. Dredging done during the previous 2030 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 fiscal year involved a cost of $223.01; repairs to concrete super- structure on the outer 100 linear feet of the north pier done dur- ing the previous fiscal year involved a cost of $1,500.80; and miscellaneous repairs to superstructure shoreward from the outer end of the north breakwater done during the previous fiscal year involved a cost of $1,721.40. All work was done by hired labor and use of Government plant. The total cost was $23,275.36 for maintenance. The total expenditures were $25,874.44. Condition at end of fiscal year.-The existing project was com- pleted in 1938. The south pier was completed in 1904. Construc- tion of the north breakwater was commenced in October 1913 and completed in October 1915. Dredging of the turning basin was commenced in October 1928 and completed in September 1931. Dredging of the entrance channel to existing project depth, was commenced in June 1938 and completed in July 1938. The piers and' breakwater are in generally good condition. The inner 260 feet of the south pier has been replaced with a revetment by private interests under permit granted July 16, 1931, by the Secretary of War. The pier is therefore maintained only for a length of about 2,490 feet. The controlling depths at low-water datum at the close of the fiscal year were 24 feet at the entrance for 500 feet, thence 21 feet in channel and turning basin. Sheboy- gan River is navigable for a distance of about 2.4 miles above its mouth for craft drawing not more than 2 feet. The costs under the existing project were $446,771.38 for new work and $697,- 395.43 for maintenance, a total of $1,144,166.81. The total expen- ditures were $1,145,003.38.

Operations and results during fiscal year.-Operations consisted of placing 948.8 tons of stone as riprap along the north break- water at a cost of $6,914.01. Soundings were taken at a cost of $286.51. Dredging done during the previous fiscal year involved a cost of $253.05. All work was done by hired labor and use of Government plant. The total cost was $7,453.57 for maintenance. The total net expenditures were $8,504.69. Condition at end of fiscal year.-The existing project was com- pleted in 1936. Construction of the north breakwater and the re- moval of the outer portion of the north pier were commenced in April 1934 and completed in December 1934. Dredging of the en- trance channel, outer turning basin, and the interior basins to ex- isting project depth, was commenced in July 1934 and completed in December 1934. Construction of the south breakwater was com- menced in July 1936 and completed in October 1936. The break- waters and the north stub pier are in good condition. The original south pier, completed in 1893, was entirely removed in 1932 by private interests under permit granted October 25, 1930, by the Secretary of War and replaced with a coal wharf. A south rubble mound breakwater about 500 feet long was constructed in 1934 by private interests as an extension of their coal wharf in accordance with local cooperation requirements of House Document 168, Seventy-second Congress, first session. The controllinig depth at low-water datum at the close of the fiscal year was 21 feet in the Government entrance channel and turning basin. The interior basins had a controlling depth of 16 feet. The area between the south line of the Government entrance channel and the harbor face of the private coal wharf, which is maintained by private interests, had a controlling depth of 21 feet.

MILWAUKEE HARBOR, WIS. Location.-On the west shore of Lake Michigan, distant about 85 miles northerly from Chicago and about 83 miles west of Grand Haven, Mich. (See U. S. Lake Survey Chart No. 743.) Previous projects.-The original project for improvement of Milwaukee Harbor was adopted by act of March 3, 1843, and modi- fied by River and Harbor Acts of August 30, 1852, April 10, 1869, and March 3, 1899. The original project for the harbor of refuge 2034 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 was adopted by River and Harbor Act of March 3, 1881. The proj- ect of June 13, 1902, consolidating the harbor and harbor of refuge was modified by River and Harbor Act of March 3, 1905. For fur- ther details see page 1938 of Annual Report for 1915 and page 1462 of Annual Report for 1938. Existing project.-This provides for a north breakwater 9,954 feet long and a south breakwater 9,671 feet, more or less, in length, extending to the shore, thereby forming a protected basin in which is being developed a commercial harbor by the city of Milwaukee, the width of entrance between the two breakwaters being about 500 feet. It further provides for the protection of the river mouth by two piers, 358 feet apart at the outer ends and 552 feet apart at the shore line, 1,656 and 1,608 feet in length for the north and south piers, respectively; for a channel 21 feet deep, extending from that depth in the lake to the mouth of the river, a total length of about 2,850 feet, the width of channel outside the piers to be 600 feet; for dredging channels 21 feet deep in the rivers from the inner ends of the entrance piers to the North Humboldt Avenue Bridge on the Milwaukee River, to a point 100 feet west of the west line of North Twenty-fifth Street extended, on the Menomo- nee River and to the South Kinnickinnic Avenue Bridge on the Kinnickinnic River; for dredging to 21 feet a portion of the outer harbor between East Wisconsin Avenue extended and East Bay Street extended and easterly of a line 50 feet lakeward of the pier head line; and the abandonment of so much of the previous project as related to dredging inside the shore line for the formation of turning basins and widening channels. The breakwaters are formed of stone-filled timber cribs and concrete caissons, all of which are capped with concrete superstructure. The inner en- trance piers are formed of concrete caissons, stone-filled timber cribs, and piling and are also provided with concrete superstruc- ture. 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 about 11/2 feet above or below the mean lake level prevailing at the time. The estimate of cost for new work, revised in 1949, was $4,894,- 000, exclusive of the amounts expended on previous projects. The latest (1945) approved estimate for annual cost of maintenance is $113,000.

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. Terminal facilities.-Besides four car-ferry slips, there are nu- merous wharves, private and municipal, used for the handling of coal, grain, building materials, cement, petroleum products, and miscellaneous 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. Operationsand results during fiscal year.-Operations consisted of removing shoals in the Menomonee, Milwaukee, and Kinnickin- nic Rivers, by contract, at a cost of $117,959.21. Repairs to con- crete superstructure on the north breakwater, in progress at the close of the previous fiscal year, were completed at a cost of $81,933.33. Placing 9,467.4 tons of stone as riprap along the breakwaters cost $59,112.69. Minor repairs to the south break- water cost $2,350.52. Soundings were taken at a cost of $1,761.86. All work, except removal of shoals in rivers, was done by hired labor and use of Government plant. The total cost was $263,- 117.61 for maintenance. The total net expenditures were $266,- 754.84. Condition at end of fiscal year.-The project in effect prior to the modifications of August 30, 1935, and March 2, 1945, was completed in 1934. No work has been done on deepening the outer harbor area to 21 feet north of the inner entrance piers, nor on 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 construction of the south pier was commenced in April 1909 and completed in No- vember 1910. Construction of the south breakwater and shore connection was commenced in May 1925 and completed in October 2036 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 1929, except for placing additional riprap and rebuilding about 756 feet of the breakwater damaged by a storm of October 22-23, 1929. Rebuilding the damaged section of the south breakwater and the placing of additional riprap were commenced in April 1931 and completed in August 1932. Dredging for deepening and widen- ing the entrance channel to existing project depth and width, was commenced in May 1929 and completed in September 1930. Plac- ing additional small stone around the caisson breakwaters to chink the voids in the large riprap was commenced in 1930 and com- pleted 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 on the timber crib section of the north breakwater and on the harbor piers are showing some dis- integration, and require repairs. The south breakwater and shore connection 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. The costs under the existing project were $4,- 537,812.20 for new work, $1,406,589.74 for maintenance, a total of $5,944,401.94. The total expenditures were $5,944,638.43. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $94.63, plus accounts receivable of $236.49, plus an anticipated allotment of $65,000 during fiscal year 1951, a total of $65,331.12 will be applied as follows: Maintenance: Operation of U.

RACINE HARBOR, WIS. Location.-On the west shore of Lake Michigan, distant about 26 miles southerly from Milwaukee and about 64 miles northerly from Chicago. (See U. S. Lake Survey Chart No. 745.) Previous projects.-The original project was adopted by the citizens of Racine about 1842 or 1843. The citizens' project was modified by acts of June 23, 1866, March 3, 1899, and June 13, 1902. For further details, see page 1939 of Annual Report for 1915 and page 1465 of Annual Report for 1938. Existing project.-This provides for a north breakwater 2,640 feet long extending from shore at a point about 1,350 feet north of the remaining 180 feet of pier on the north side of the channel at the mouth of Root River, and for a south breakwater 2,652 feet long extending fkom the city rubble mound about 1,650 feet south of the remaining 22.5 feet of pier on the south side of the channel at the mouth of the river. It further provides for a channel, through the outer basin, 23 feet deep from that depth in the lake to a point about 400 feet inside the entrance, thence 21 feet to a point about 750 feet westward of the outer end of the north stub pier, with widths of 350 feet at the entrance, increasing to 1,000 feet through the outer harbor and decreasing to 190 feet in the river to a point about 750 feet westward of the outer end of the north stub pier, the total: length of channel being about 2,300 feet; thence a channel 19 feet deep in Root River to a point about 195 feet below the north line of Bridge Street extended, a distance of about 2,900 feet, with widths of 190 feet at the lower end reduc- ing to 95 feet at the upper end, with intermediate reductions and enlargements; and removal of shoals about one-half mile lake; ward of the harbor entrance to a minimum depth of 25 feet. The breakwaters and south stub pier are formed of stone-filled timber cribs, concrete caissons, and piling, all being capped with concrete superstructures. The north stub pier is formed of stone-filled steel-sheet piling.. 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 2038 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 foot above or below the annual mean stage, and extreme fluctua- tions 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 1945, was $771,- 000, exclusive of the amounts expended on previous projects and exclusive of inner 300 linear feet of pile pier and 450 linear feet of rubble mound, originally part of south breakwater but no longer considered necessary. The latest (1948) approved estimate for annual cost of maintenance is $41,000.

Operations and results during fiscal year.-Operationsconsisted of dredging 29,855 cubic yards of material for restoration of project depth at a cost of $16,884.53. Placing 4,011.8 tons of stone as riprap along the north breakwater cost $23,173.41. Soundings were taken at a cost of $555.97. Preliminary plans for future breakwater repairs were made at a deferred cost of $440.04. All work was done by hired labor and use of Government plant. The total cost was $40,613.91 for maintenance. The total net expendi- tures were $38,669.21. Condition at end of fiscal year.-The existing project was sub- stantially completed in 1946. Construction of the north breakwater and shore connection was completed in November 1918. Removal of the old north pier was completed in 1913. Construction of the south breakwater and shore connection and the removal of the old south pier were commenced in June 1916 and completed in De- cember 1924. Removal of the outer shoals widening and deepening the channel through the outer basin to existing project depth and width, and dredging of the river channel were commenced in July 1946 and completed in November 1946. The concrete superstruc- ture, on north breakwater and shore connection is disintegrating and requires repairs. The south breakwater and shore connection and stub piers are in generally good condition. The controlling depths at low-water datum at the close of the fiscal year were 21 feet in the channel through the outer basin and for a distance of about 800 feet in the river, thence 18.1 feet to the upper limit of the project. The costs under the existing project were $777,774.65 RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2039 for new work and $504,283.89 for maintenance, a total of $1,- 282,058.54. The total expenditures were $1,282,442.98. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $18,081.13, plus an anticipated allot- ment of $115,000 during fiscal year 1951, a total of $133,081.13 will be applied as follows: Accounts payable June 30, 1950 ............................ $70.23 Maintenance: Ope ,ration of U.

For further details see page 1939 of Annual Report for 1915 and page 1468 of Annual Report for 1938. Existing project.-This provides for a detached breakwater 796 feet long, and for two parallel piers about 250 feet apart, 1,077 2040 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 feet and 1,872' feet in length for the north and south piers, respec- tively. It further provides for an entrance channel 200 feet wide and 21 feet deep, from that depth in the lake a distance of 2,750 feet to an interior basin 21 feet deep; and for a channel 21 feet deep and generally 70 feet wide, extending 475 feet northwesterly from the northwest corner of the interior basin to within 35 feet of the Fiftieth Street bridge. The breakwater is formed of stone- filled timber cribs; the piers are formed of stone-filled timber cribs and piling. The entire north pier, 1,175 feet of the south pier, and the entire breakwater are capped with concrete super- structure. The inner 697 feet of the south pier has:been provided with a steel sheet pile face. 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 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 1950, was $75,100, exclusive of amounts expended on previous projects and excluding $3,000 to be contributed by local interests. The latest (1948) approved estimate for annual cost of maintenance is $24,000.

Terminal facilities.-There are several wharves used for han- dling coal, building materials, and miscellaneous commodities, and also several fishing wharves. While these facilities are considered generally adequate for existing commerce, more efficient use of existing terminals and utilization of available frontage for de- velopment of additional terminals should be made. Operationsand results during fiscal year.-Operationsconsisted of dredging 41,967 cubic yards of material for restoration of project depth at a cost of $18,666.57. Soundings were taken at a RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2041 cost of $579.28. Dredging done during the previous fiscal year involved a cost of $445.23. All work was done by hired labor and use of Government plant. The total cost was $19,691.08 for main- tenance. The total net expenditures were $21,318.68. Condition at end of fiscal year.-The project in effect prior to the modification of May 17, 1950, was completed in 1936. No work has been done on the last modification of the project providing for a channel northwesterly from the basin. The north pier completed in 1895, the south pier in 1900, and the breakwater in 1909, are in generally good condtion. Dredging of the entrance channel and interior basin to existing project depth, was commenced in October 1935 and completed in April 1936. The controlling depth at low-water datum at the close of the fiscal year was 21 feet in the entrance channel and inner basin.

Local interests were notified on November 5, 1945, of the required conditions and requested to furnish assur- ances that they will be met. Negotiations for required easements, rights of way and spoil disposal areas are in progress. All prior requirements have been complied with. Terminal facilities.-There are several wharves used for han- dling coal, building materials, petroleum products, and miscella- neous commodities and three shipbuilding yards. A package- freight terminal is also available for use. While these facilities are generally adequate for existing traffic conditions, a public wharf open for all on equal terms should be provided. Operationsand results during fiscal year.-Operations consisted of dredging 204,341 cubic yards of material for restoration of project depth at a cost of $58,100.21. Soundings were taken at a cost of $1,691.80. All work was done by hired labor and use of Government plant. The total cost was $59,792.01 for maintenance. The total net expenditures were $58,844.94. Condition at end of fiscal year.-The project in effect prior to the modification of March 2, 1945, was completed in 1938. No work has been done on the last modification of the project providing for a turning basin just above the mouth of the Morrison Channel. The piers and revetments completed in 1904 are in generally good condition except that a portion of the north revetment requires repairs. Dredging of the channel to existing project depth, was commenced in August 1938 and completed in October 1938. The controlling depths at low-water datum at the close of the fiscal year were 21 feet in the channel to Benton Harbor Canal and 16.4 feet in Benton Harbor Canal to Ninth Street. The costs under the existing project were $366,683.16 for new work and $984,- 647.37 for maintenance, a total of $1,351,330.53. The total ex- penditures were $1,351,179.72.

Operations and results during fiscal year.-New work: Opera- tions consisted of completing, by contract, the widening of the ex- isting 200-foot channel between the Grand Trunk Western Rail- 2052 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19 50 way bridge and the Grand Trunk Western car-ferry slip to 300 feet and 21 feet deep, and dredging a turning basin 18 feet deep downstream from the Grand Trunk Western Railway bridge. A total of 200,462 cubic yards of material was removed at a cost of $86,572.58. Dredging 47,575 cubic yards of material in modifica- tion of the turning basin, by hired labor and use of Government plant, cost $27,632.97. Maintenance: Operations consisted of dredging 57,900 cubic yards of material for restoration of project depth below the Grand Trunk Western Railway bridge at a cost of $20,228.22. Dredging 111,897 cubic yards of material for restoration of project depth in the river above the Grand Trunk Western Railway bridge cost $32, 411.81. Construction of an earth dike training wall and widen- ing of the channel in vicinity of Potato Island on Grand River cost $28,719.49. Placing 915.5 tons of stone as riprap and filling along the piers cost $7,021.96. Soundings were taken in the harbor channel at a cost of $2,134.27 and in the river channel at a cost of $1,585.48. Dredging below the Grand Trunk Western Railway bridge done during the previous fiscal year involved a cost of $835.74. Preliminary plans for future work were made at a de- ferred cost of $771.92. All work was done by hired labor and use of Government plant. The total cost was $114,205.55 for new work and $92,936.97 for maintenance, a total of $207,142.52. The total net expenditures were $157,920.73 for new work and $109,- 005.94 for maintenance, a total of $266,926.67. Condition at end of fiscal year.-The existing project is about 98 percent complete. The work remaining to be done consists of 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 con- sidered adequate for present and reasonably prospective com- merce. The piers and revetments were completed in 1893 and are in generally good condition except that the south revetment re- quires repairs. Dredging of that portion of the channel between the car-ferry slip and the Grand Trunk Railway bridge to a width of 200 feet, was commenced in August, 1930, and completed in October, 1930, with advanced funds. Dredging of the river above the railway bridge to Bass River to existing project depth, was commenced 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 turn- ing basin on the south side of the channel just below that bridge, was commenced in October, 1948, and completed in September, 1949. The controlling depths at low-water datum at the close of the fiscal year were 22 feet between the piers, thence 21 feet in' the river to the Grand Trunk Railway bridge, and thence 8 feet to Bass River and 17 feet in the outlet from Spring Lake. The costs under the existing project were $964,850.65 for new work and RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2053 $2,266,970.80 for maintenance, a total of $3,231,821.45.

ARMY, 1950 pier; for repairing and maintaining the revetment around the old car-ferry slip on the south side of the entrane channel; for dredg- ing channel 380 feet wide at the entrance, thence increasing to 650 feet wide at a point about 300 feet inside the entrance, thence decreasing toward the new pierheads to 500 feet wide and 240 feet wide between the piers, with depths varying from 24 feet at the harbor entrance to 21 feet at the shore line and in the inner chan- nel to Muskegon Lake, about 6,050 feet from the harbor entrance. The south breakwater and shore connection are built of concrete caissons and piling capped with concrete; the north breakwater is a rubble mound; the inner piers and revetments are built of stone-filled timber cribs and piling, all having been capped with concrete. 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 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 1935, was $1,- 885,000, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $28,000.

Local cooperation.-Fully complied with. Terminal facilities.-The main terminals are at the city of Mus- kegon, at the inner end of Muskegon Lake, and include a car-ferry slip, a large privately owned wharf equipped with warehouse, transit shed, and cold-storage plant, and several wharves used for handling coal, petroleum products, building materials, and miscel- laneous commodities. There is also a sand wharf at the west end of Muskegon Lake south of the inner end of the improved channel. These facilities are considered adequate for existing commerce. Operationsand results during fiscal year.-Operations consisted of dredging 42,941 cubic yards of material for restoration of proj- ect depth at a cost of $6,263.37. Repairs to outer end of north rubble mound breakwater cost $20,536.17. Placing 2,822 tons of stone as riprap along the south breakwater cost $17,898.82. Sound- ings were taken at a cost of $1,560.89. Dredging done during the previous fiscal year involved a cost of $597.54. All work was done RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2055 by hired labor and use of Government plant. The total cost was $46,856.79 for maintenance. The total net expenditures were $51,114.85. Condition at end of fiscal year.-The existing project was com- pleted in 1938. Construction of the south breakwater and shore connection was commenced in May, 1928, and completed in De- cember, 1930. The construction of the north breakwater and shore connection and the removal of portions of the old piers were com- menced in June, 1930, and completed in December, 1931. Deepen- ing and widening of the entrance channel to existing project depth and width, was commenced and completed in June, 1932. Repairs to the south revetment around the old car-ferry slip were com- menced in May, 1938, and completed in October, 1938. The outer 54 feet of the south breakwater were removed in 1939, thereby increasing the width between the outer ends of the breakwaters to 555 feet. The south breakwater is therefore maintained for only a length of about 1,460 feet. The breakwaters and shore connec- tions are in generally good condition. The inner piers and revet- ments are in fair condition. The controlling depths at low-water datum at the close of the fiscal year were 23 feet in the channel through the outer harbor and 21 feet between the inner piers to Muskegon Lake. The costs under the existing project were $1,900,922.07 for new work and $629,872.58 for maintenance, a total of $2,530,794.65. The total expenditures were $2,534,097.62. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $388.87, plus accounts receivable of $3,304.92, plus an anticipated allotment of $32,000 during fiscal year 1951, a total of $35,693.79 will be applied as follows: Accounts payable June 30, 1950 .............................. $1.95 Maintenance: Operation of U.

PETOSKEY HARBOR, MICH. Location.-This harbor is on the east shore of Lake Michigan, distant about 293 miles northeasterly from Chicago and about 92 miles northerly from Frankfort, Mich. (See U. S. Lake Survey Chart No. 706.) Previous projects.-The original project was adopted by the River and Harbor Act of September 19, 1890 and modified by the River and Harbor Act of July 13, 1892. For further details see page 1954 of Annual Report for 1915 and page 1547 of Annual Report for 1931. Existing project.-This provides for a west breakwater, extend- ing from shore, having a total length of 1,345 feet. The break- water is built of stone-filled timber cribs and rubblestone. The timber cribs are capped with concrete superstructure. The fluctuations of water level are seasonal change 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 1894, was $170,- 000, exclusive of amount expended on previous project. The latest (1948) approved estimate for annual cost.of maintenance is $1,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Aug. 18, 1894 Breakwaters according to larger of two projects-._____ Annual Report, 1890, p. 2673, and Anual Report, 1895, p. 2819.

RIVERS AND HARBORS-MILWAUKEE, WIS., DISTRICT 2073 Local cooperation.-None required. Terminal facilities.-These consist of a municipal wharf pro- jecting about 635 feet beyond the shoreline and protected by the breakwater. This wharf is considered adequate for the existing commerce. Operations and results during fiscal year.-Operations consisted of repairs to the rubble mound shore connection, by contract, at a cost of $16,121.57 for maintenance. The total net expenditures were $16,121.57. Condition at end of fiscal year.-The existing project was com- pleted in 1908. The breakwater, constructed during the period 1895 to 1908, is in generally good condition. The available depth at low-water datum at the close of the fiscal year was about 11 feet at the end of the municipal wharf. The costs and expenditures under the existing project were $118,016.18 for new work and $91,165.59 maintenance, a total of $209,181.77. Proposed operations.-No work is scheduled for fiscal years 1951 and 1952.

Location.-This harbor is on the west shore of Lake Michigan, distant about 51 miles south of Milwaukee and about 38 miles north from Chicago. (See U. S. Lake Survey Chart No. 74.) 2079 2080 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Previous project.-An appropriation was made by the River and Harbor Act of August 30, 1852, for a breakwater. This work was abandoned. The original project was adopted by River and Harbor Act of June 14, 1880, and modified by River and Harbor Act of August 2, 1882. For further details see page 1940 of An- nual Report for 1915, and page 1508 of Annual Report for 1938. Existing project.-This provides for- (a) A northerly exterior breakwater about 1,900 feet long ex- tending easterly from the shore 1,030 feet and thence southeasterly 870 feet to the outer end, forming a protected outer harbor. (b) Parallel piers, from the outer harbor to an inner basin, about 240 feet apart and 1,613 and 3,212 feet long for the north and south piers, respectively, the inshore end of the south pier di- verging southward opposite the inner basin. (c) An entrance channel 390 feet wide and 22 feet deep extend- ing from that depth in the lake to the outer end of the north pier, reducing to a channel between piers 200 feet wide and 18 feet deep to the inner basin, an inner basin 18 feet deep, about 13 acres, protected on the east side by a revetment 882 feet long, and an anchorage area 8 feet deep, about 6 acres, in the southwest corner of the inner basin. 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 about 11/2 feet above or below the mean lake level prevailing at the time. The estimated cost of new work, revised in 1950, is $586,300, exclusive of amounts expended on previous projects, and excluding $20,000 (cost of bulkhead and boat stalls) to be contributed by local interests. The latest (1948) approved estimate for annual cost of maintenance is $19,750, on completion of the project. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents June 14, 1880 Aug. 2, 1882 Parallel piers and basin'_....._ .-..

Local cooperation.-The act of March 2, 1945, provided that dredging of the anchorage basin shall not be commenced until local RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 2081 interests furnish assurances to the Secretary of War that they will remove the abandoned water intake pipes; construct an adequate bulkhead in front of the city park and in front of the adjacent United States property; furnish, free of cost to the United States, the land necessary for the anchorage area; release the United States from all claims for damages resulting from the improve- ment and provide and maintain adequate mooring facilities. Local interests were informed of requirements on July 1, 1946. Permit authorizing construction of the required bulkhead was issued by Department of the Army on August 25, 1948 and compliance with the remaining requirements is anticipated on completion of the bulkhead. Terminal facilities.-These consist of a wharf 1,000 feet long, owned by the Chevrolet-Saginaw Grey Iron Foundry Division, equipped with a coal-handling tower, and two coal wharves and one fishing wharf owned by the city of Waukegan. The facilities are considered adequate for existing commerce. Operations and results during fiscal year.-Miscellaneous sur- veys were conducted by hired labor at a cost of $3,971.48. Pre- liminary operations for reconstruction of 327 lineal feet of the revetment adjoining United States property on the east side of the inner basin were completed by hired labor at a cost of $1,- 299.05. Reconstruction of revetment was accomplished by con- tracts at a cost of $42,526.17. Plans for dredging in the entrance channel were completed by hired labor at a cost of $445.87; 29,640 cubic yards of material were dredged from the harbor, by contract, at a cost of $34,040.83. The breakwater was repaired, by contract, at a cost of $13,894.13; 836.83 tons of riprap were placed. The total costs for the fiscal year were $96,177.53, all maintenance. The total expenditures were $54,036.14. Condition at end of fiscal year.-The existing project is 92 percent complete. The work remaining to be done to complete the project consists of dredging to provide an anchorage area in the southwest corner of the inner basin. The north pier and east revetment were completed in 1904 and the south pier in 1909. The outer 600 feet of breakwater were completed in 1904, and the shore-arm extension in 1931. All structures are in good condi- tion. The controlling depths are 22.2 feet in the entrance channel to the outer end of the south pier and 18 feet in the remaining portion of the entrance channel and inner basin. Depths are based on soundings taken in September 1949 and June 1950 and are referred to low-water datum. The mean-water level in June 1950 was 1.06 feet above datum. The total cost to June 30, 1950, was $1,519,281.93, of which $536,757.92 was for new work and $982,524.01 for maintenance. Total expenditures were $1,476,778.01. Proposed operations.-The balance unexpended at the end of the fiscal year, amounting to $42,806.04, plus an anticipated allot- ment of $5,000 during fiscal year 1951; a total of $47,806.04; will be applied as follows: 2082 REPORT OF CHIEF OF ENGINEERS, U.

CHICAGO HARBOR, ILL. Location.-NortheasternIllinois, near the southern end of Lake Michigan; 85 miles in a southerly direction from Milwaukee, Wis. (See U. S. Lake Survey Chart No. 752.) Previous projects.-Adopted by River and Harbor Act of March 2, 1833, and modified by River and Harbor Acts of June 23, 1866; March 2, 1867; July 1, 1868; and April 10, 1869. Work was con- tinued under these projects until 1870. (For further details see p. 1941 of Annual Report for 1915 and p. 1510 of Annual Report for 1938.) Existing project.-This provides for the following work: (a) An inner breakwater, all of timber cribs, enclosing an inner basin of about 224 acres in extent, the breakwater being in two sections, as follows: The main inner breakwater 4,036 feet long with 300 feet of shore return on north end; a southerly extension 2,550 feet long. (b) An exterior breakwater enclosing an outer basin of about 970 acres in extent, the breakwater being in three sections, ex- clusive of gaps, as follows: The shore extension at north end built of timber cribs and 2,250 feet long; the main exterior breakwater, built of timber cribs and 5,413 feet long; and the southerly ex- tension, built of rubble mound and concrete caissons and 5,000 feet long, exclusive of the harbor entrance gap of 500 feet. (c) Maintenance dredging to a depth of 21 feet of that part of the inner basin lying north of a line drawn eastwardly perpen- dicular to the eastern boundary of Grant Park, from the northern end of said boundary, and also of the entrance to Chicago River from the lake to Rush Street over a width varying from 470 to 190 feet. (d) Maintenance of that section of the north pier, 900 feet long, located east of the entrance to Ogden slip. RIVERS AND HARBORS--CHICAGO, ILL., DISTRICT 2083 The project depth is referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. Seasonal fluctuations in mean stage from low water in winter to high water in summer average about 1.2 feet. Local and tempo- rary 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 1914, was $3,- 686,500, exclusive of amounts expended on previous projects. The latest (1928) approved estimate of annual cost of maintenance is $50,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents July 11, 1870 Inner breakwaters and inner basin_ --- H. Ex.

The latest published map of this harbor is in the Annual Report for 1914, opposite page 2924. Local cooperation.-Fully complied with. Terminal facilities.-The outer harbor terminals consist of two slips, one opening off from the main river and one, with dock space of 1,500 feet, opening off from the inner basin; 3 wharves, fronting on the river itself, and a United States Navy pier extend- ing into the outer basin from the lake front at the outer end of Grand Avenue. The United States Navy pier is not available to commercial navigation. The outer harbor facilities are not entirely adequate for existing commerce. Operations and results during fiscal year.-Miscellaneous sur- veys were conducted by hired labor at a cost of $10,374.95. Pre- liminary work for repair of shore-arm extension of the exterior breakwater was continued by hired labor at a cost of $5,933.79. Repairs were initiated to one-half of the structure, by contract, and 70 percent of the work was completed at a cost of $149,458.04. One deteriorated wood-pile clump was removed and two new pile clumps were constructed, by contract, at a cost of $5,696.31. Con- tract plans for dredging the harbor entrance channel were com- pleted by hired labor at a cost of $539.89. Dredging, by contract, involved the removal of 6,000 cubic yards of material at a cost of $5,865.73. Breakwater repairs, by contract, involved the place- ment of 2,576.2 tons of stone at a cost of $42,551.80. The total 2084 REPORT OF ,CHIEF OF ENGINEERS, U. S. ARMY, 1950 costs for the fiscal year were $220,420.51, all maintenance. The total expenditures were $120,686.02. Condition at end of fiscal year.-The existing project was com- pleted in 1923. The entrance to Chicago River has been improved by the construction of parallel entrance piers, and dredging of a channel 190 by 470 feet in width and a depth of 21 feet below datum. The northerly arm of the inner breakwater (timber 4,034 feet, with 304 feet of shore-return on the north end, completed in 1874; concrete superstructure completed in 1934) is in good con- dition except for an experimental section about 100 feet long which has failed. The southerly arm (timber 2,544 feet, completed in 1880; concrete superstructure completed in 1930), is in good condition. The exterior breakwater (timber 5,418 feet, completed in 1889; concrete superstructure completed in 1930), the southerly extension (rubble mound 2,227 feet, completed in 1917), and the south arm (rubble mound 1,532 feet, completed in 1920; and concrete caisson 1,185 feet, completed in 1923) are in good condi- tion. The shore-arm extension (timber 2,250 feet, completed in 1917) has deteriorated above the water line. In 1950, approxi- mately 40 percent of the deteriorated portion was replaced by a concrete superstructure. The north pier (concrete superstructure, 975 feet, completed in 1908 and repaired in 1949) is in good condition. The controlling midchannel depth from the west end of the lock near the mouth of the Chicago River, to the Michigan Avenue Bridge, is 21 feet. Depths are based on soundings taken in December 1949, and are referred to low-water datum. The mean-water level in June 1950 was 1.06 feet above datum. The total cost to June 30, 1950 was $5,620,004.27, of which $3,409,844.22 was for new work and $2,210,160.05 for mainte- nance. The total expenditures were $5,515,948.68. Proposed operations.-The balance unexpended at the end of the fiscal year, amounting to $192,297, plus an anticipated allot- ment of $413,000 during fiscal year 1951, a total of $605,297, will be applied as follows: Accounts payable, June 30, 1950 .......................... $104,055.59 Maintenance : Sounding, sweeping, and miscellaneous investigations, by hired labor, fiscal year 1951 ........................ 8,000.00 Completion of repairs to superstructure of shore-arm ex- tension breakwater, by contract, July 1, 1950 to June 30, 1951 ........................................ 442,650.00 Repair superstructure of inner breakwater by contract, Sept. 1, 1950 to June 30, 1951 ........................ 50,591.41 Total ............................................ 605,297.00 No work is scheduled for fiscal year 1952.

Local cooperation.-The act of July 24, 1946, provided.that the improvement of the channel is subject to the condition that local interests furnish assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from damages which may result from construction and maintenance of the improvement. The above requirement has not been complied with. Terminal facilities.-In the Chicago River and its branches there is a total wharfage, including numerous slips of about 150,- 000 feet, about 15,000 feet of which is used by private interests for shipping purposes. These terminals are owned and operated by steamship lines, grain, coal, and lumber companies, and various other industries. They are more than adequate in extent for exist- ing commerce. Except for the State of Illinois barge terminal and elevator at Damen Avenue on the south branch (mentioned in terminal facilities on the Illinois River), and the frontage along Wacker Drive, owned by the city, there are no publicly owned docks, wharves, or other terminal facilities on the main river or its branches. Operations and results during fiscal year.-Miscellaneous sur- veys were conducted by hired labor at a cost of $5,900.23. Dredg- ing, by contract, involved the removal of 207,057 cubic yards of material and was completed at a cost of $193,883.49. The total cost for the fiscal year was $199,783.72, all maintenance. Total expenditures were $105,428.54. Condition at end of fiscal year.-The project is complete except for the work authorized by the River and Harbor Act of July 24, 1946.

CALUMET HARBOR AND RIVER, ILL. AND IND. Location.-NortheasternIllinois (Cook County), near the south- ern end of Lake Michigan, 121/2 miles south of Chicago Harbor, 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 anchor- age behind same, which are in Indiana. The Calumet River is within the Chicago city limits. (See U. S. Lake Survey Chart No. 75.) For description, see page 1471 of Annual Report for 1932. 2088 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 an approach channel 3,200 feet wide and 28 feet deep through the shoals outside the breakwater. (c) For an outer harbor channel and anchorage area 3,000 feet wide and 26 feet deep. (d) For an entrance channel to the river 350 feet wide and 26 feet deep to the Elgin, Joliet & Eastern Railway bridge. (e) For a channel in Calumet River of 200-foot minimum width, 25 feet deep to the Semet-Solvay wharf near One Hundred and Eleventh Street, thence 23 feet deep through the rock section to near One Hundred and Fourteenth Street, thence 21 feet deep to One Hundred and Twenty-second Street, and thence 21.5 feet deep to and including turning basin No. 5. (f) For widening and straightening the river channel, except through the rock cut, to within 20 feet of bulkhead lines now or hereafter established. (g) For five turning basins spaced along the river channel, of suitable 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 Michigan seasonal fluctuations in mean stage from low water in winter to high water in summer average about 1.2 foot. Local and tem- porary fluctuations of 0.1 to 0.5 feet, 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 1950, is $10,694,- 000, exclusive of amounts expended on previous projects. The latest (1950) approved estimate of annual cost of maintenance is $115,000. The existing project was adopted by the following river and harbor acts: RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 2089 Acts Work authorized Doucments Mar. 3, 1899 \ Annual Report, 1896, pp. 2584, et June 13, 1902 f Outer harbor protected by breakwater ------------- seq., and H.

Local cooperation.-The act of March 3, 1905, required as a con- dition precedent to Federal expenditures upon any one of the five turning basins the donation to the United States of the land neces- sary for that turning basin and have either provided any necessary bulkheads or have released the United States from all damage to adjacent lands by reason of the excavation. As a result the land needed for turning basins, 1, 3, and 5 has been conveyed to the United States. The total area thus conveyed is 17.85 acres, and the value of the land at the time of its conveyance was approxi- mately $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 dam- ages 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 One Hundred and Twenty-second Street, to replace the original turning basin 3, and has constructed a bulkhead along the channel side of the original basin 3, and reclaimed the area to provide land for plant expansion. The corporation has 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 two portions of the east side of the river between the south end of the rock section and turning basin 3, mile 4.7. Local interests donated the necessary land for the widening. Terminal facilities.-All terminal facilities on the lake front and in the entrance channel up to the Elgin, Joliet & Eastern Railway bridge are owned and operated by two steel companies, except a 450-linear-foot reservation owned by the Corps of Engineers. These facilities consist in part of two slips which are 2,900 and 1,300 feet long, respectively, and also of about 2,961 feet of wharf- 939127--51-vol. 2--42 2090 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 age facing on the entrance channel. These terminals are fully equipped and are considered adequate for existing commerce. Ad- ditional dockage exists on the lake front and along the entrance channel, but for various reasons it is not now suitable for terminal uses. Between the Elgin, Joliet & Eastern Railway bridge and The Forks there are about 50,500 feet of wharfage, including 14 slips and drydocks, of which about 31,300 feet are in use. These wharves are owned and operated by various private and industrial concerns handling ore, coal, grain, lumber, etc. About 3,600 feet are in use for shipbuilding purposes. The ore, grain, and coal wharves are fully equipped and are considered adequate for exist- ing commerce. There are no public wharves on the Calumet River. Operations and results during fiscal year.-New work: Prepa- ration of plans for closing entrance gap between the breakwaters was continued by hired labor at a cost of $43.30. Maintenance: Miscellaneous surveys were conducted by hired labor at a cost of $18,307.87. Plans for dredging entrance chan- nel and river were completed by hired labor at a cost of $494.12, and for riprapping breakwaters, $748.04. Repairs to breakwater, involving the placement of 2,431.6 tons of stone, were accom- plished by contract at a cost of $28,603.67; 175,401 cubic yards of material were dredged from the river and the entrance chan- nel, by contract, at a cost of $161,979.02. The total cost for the fiscal year was $210,176.02, of which $43.30 were for new work and $210,132.72 for maintenance. Total expenditures were $207,- 150.16. Condition at end of fiscal year. The existing project is 52 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, widening, and straightening the Calumet River; dredging an approach channel to the harbor through the shoals outside the detached breakwater; and closing the gap between the breakwaters. The timber break- water (6,712 feet, completed in 1904; concrete superstructure completed in 1924) and the cellular type steel-sheet pile break- water (5,007 feet, completed in 1935) are in good condition. Under permit from the Secretary of War, the Youngstown Sheet & Tube Co. and its predecessors 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 has 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 channel adjoining the new bulkhead except along the rock section, where the widening was done by the corporation. Depths in the outer harbor vary from 21 to 28 feet. The control- ling midchannel depth in the river is 19.1 feet, up to and including turning basin 5. Depths are based on soundings taken in August 1949, and February 1950, and are referred to low-water datum. The mean water level in June 1950 was 1.06 feet above datum. RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 2091 The head of navigation for deep-draft vessels in the river is at turning basin 5 at the entrance to Lake Calumet.

LAKE CALUMET, ILL. Location.-Northeastern Illinois (Cook County), within the southeasterly limits of the city of Chicago, just west of and con- nected by a short channel with turning basin 5, the landward limit of the project known as Calumet Harbor and River. (See U. S. Lake Survey Chart No. 755.) Existing project.-This provides for dredging areas A and B in the south end of Lake Calumet, including an entrance channel 300 feet in width from turning basin 5, to a depth of 21 feet. 2092 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The project depth is referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. Fluctuations in stage, of the lake are practically those resulting from changes of water level in Lake Michigan. On Lake Michigan seasonal fluctuations in mean stage from low water in winter to high water in summer average about 1.2 feet. Local and tempo- rary 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 made in 1933, was $460,500. The latest (1945) approved estimate for annual cost of mainte- nance is $22,400. The existing project was authorized by the River and Harbor Act of August 30, 1935 (H. Doc. 180, 73d Cong., 2d sess.). The latest published map of the Illinois Waterway is in House Docu- ment 145, Seventy-sixth Congress, first session. Local cooperation.-Fullycomplied with. Terminal facilities.-One terminal facility, owned and operated by Calumet Harbor Terminals Co., is now available. Proposed terminal developments include facilities for lake, river, truck, and air freight. Operations and results during fiscal year.-Miscellaneous sur- veys were conducted by hired labor at a cost of $3,494.29, all maintenance. The total expenditures were $3,497.68. Conditions at end of fiscal year.-The existing project was com- pleted in 1937. Depths in the channel from turning basin 5 on the Calumet River to the dredged area in the lake vary from 17 to 21 feet. Depths in the dredged area, about 56.5 acres at the south end of the lake, vary from 15 to 17 feet. Depths are based on soundings taken in December 1944, and in September 1949, and are referred to low-water datum. The mean water level in June 1950 was 1.06 feet above datum. Except in the dredged area, depths in the lake vary from 1 to about 10 feet, but in general are so shallow that no navigation is possible in the undredged portion except by very light draft vessels. The total cost of the work to June 30, 1950, was $416,851.10, of which $405,011.57 was for new work and $11,839.53 for main- tenance. The total expenditures were $416,851.60. Proposed operations.-Ne work is scheduled for fiscal years 1951 and 1952.

That part of the Calumet River Branch Channel from the north line of One Hundred and Forty-first Street to the Grand Calumet River has not as yet been completed by local interests or accepted for maintenance by the United States. The project depths are referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. 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 1950, is $4,517,- 000, exclusive of amount expended on previous project. The latest (1950) approved estimate for annual cost of maintenance is $100,000.

Local cooperation.--The act of August 26, 1937, provides that the enlargement of the Indiana Harbor Canal shall not be under- taken until local interests have furnished a right-of-way 300 feet wide and have constructed substantial bulkheads along the chan- nel on the established lines shown on the map accompanying Rivers and Harbors Committee Document No. 13, Seventy-fifth Congress, first session, provided that the improvement on one side may pro- ceed in any section of fulfillment of the conditions for that side of the section, and provided further, that south of the turning basin at The Forks (beginning 450 feet south of the intersection of the present Calumet Branch and main-stem bulkhead lines) widening and deepening by the United States shall be done only as the rights-of-way and bulkheads on at least one side of the channel are continuously provided southward from the above limit of the turning basin at The Forks. 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 One Hundred and Forty-first Street and extending northward toward The Forks for a distance of about 2,107 feet, has been conveyed to and accepted by the United States. Local in- terests have also constructed 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 One Hundred and Forty-first 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. All prior requirements have been fully complied with. Terminal facilities.-There are now in existence about 24,500 feet of wharfage along the main canal and its branches. Of this amount, about 19,500 feet along the outer harbor and the inner RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 2095 harbor channel are being used by steel, oil-manufacturing, and terminal companies. About 1,400 feet of the above wharfage on the east side of the Calumet River Branch, and about 2,100 feet on the west side of the channel, are used as oil terminals. The wharves now in use are fully equipped and are considered ade- quate for existing commerce. Operations and results during fiscal year.-Miscellaneous sur- veys were conducted by hired labor at a cost of $29,356.91. Plans for dredging in the Calumet River Branch were completed by hired labor at a cost of $367.40. 59,474 cubic yards of material were removed, by contract, at a cost of $62,651.94. Cost of the work, however, was defrayed by inbursement in amount of $50,- 302.99 received from Carnegie-Illinois Steel Corp. Dredging in the harbor and in the canal was initiated, by contract, and 26,431 cubic yards of material were removed completing 60 percent of the work at a cost of $27,741.41. Adjustment of costs for dredg- ing by contract in fiscal year 1949 amounted to -$19.26. The total cost for the fiscal year was $69,795.41, all maintenance. The total expenditures were $57,976.38. Condition at end of fiscal year.-The existing project is 80 per- cent complete. The work remaining to be done to complete the existing project consists of widening 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, complete widening of the Calumet River Branch from The Forks to One Hundred and Forty-first Street to the same width and depth, and complete deepening and widening to full project dimensions of the upper 3,400 feet of the Lake George Branch. The north breakwater (rubble mound, 2,520) feet, completed in 1922) is in good condi- tion except that some riprap is required. The east breakwater (concrete caisson, 1,507 feet, completed in 1926) and northerly extension (rubble mound, 2,324 feet, completed in 1935) are in good condition except that some riprap is required. Under a per- mit from the Department, the Defense Plant Corporation has constructed a bulkhead on the east side of the canal between the Pennsylvania Railroad Bridge and Dickey Place Bridge, and the United States has widened and deepened the channel adjoining this bulkhead. The controlling midchannel depths are as follows: 27 to 30 feet in the entrance channel parallel to the rubble mound breakwater and generally 21 feet or more in the outer harbor; 20.9 feet between the bulkheads of the steel companies to the 5 bridges; 20.6 feet from the 5 bridges to the turning basin at The Forks; 22 feet in the turning basin at The Forks; from 21 feet at the basin entrance to 13.5 feet at a point 80 feet from the south side of the basin, in the turning basin east of Canal Street; 19.5 feet from the turning basin to One Hundred and Forty-first Street Bridge; and 21.8 feet from the turning basin to 900 feet above the Indianapolis Boulevard Bridge, on the Lake George Branch. Depths are based upon soundings taken from July 1948 through August 1950, and are referred to low-water datum. The mean level in June 1950 was 1.06 feet above datum. The head of navigation for commercial vessels is at the Baltimore & Ohio Chicago Termi- 2096 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 nal 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 cost to June 30, 1950, all funds, was $5,452,000.61, of which $3,833.956.12 were regular funds and $1,618,044.49 Public Works funds; $3,628,688.22 being for new work and $1,823,312.39 for maintenance. The total expenditures were $5,422,306.66, in- cluding $1,618,044.49 Public Works funds.

Lake Survey Chart No. 75.) For descriptions see page 1482 of Annual Report for 1932. RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 2097 Previous projects.-Adopted by River and Harbor Act of July 4, 1836, and work was continued under this project until 1870. For further details see page 1944 of Annual Report for 1915 and page 1524 of Annual Report for 1938. Existing project.-This provides for- (a) A detached breakwater, east and west entrance piers, and a dredged channel, 120 to 150 feet wide and 18 feet deep, from Lake Michigan to the upper of two turning basins, which are also to have a depth of 18 feet. (b) The repair and restoration of the westerly 1,000 feet of the old east breakwater. (c) Dredging an anchorage shoreward of the restored section to a depth of 12 feet in the northerly portion and 8 feet in the southerly portion. (d) Enlarging the entrance to this basin through the east pier to a width of 66 feet. The project depth is referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. 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 and 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 1935, was $1,220,- 000, exclusive of amount expended on previous project. The latest (1948) approved estimate for annual cost of maintenance is $35,500.

The terminal facilities are considered adequate for existing commerce. 2098 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Operations and results during fiscal year.-Miscellaneous sur- veys were conducted by hired labor at a cost of $2,532.09. Main- tenance dredging in Trail Creek, involving the removal of 28,417 cubic yards of material, was completed by hired labor, at a cost of $11,744.08. Repairs to breakwater were accomplished by contract at a cost of $23,247.83; 1,333 tons of stone were placed. The total costs for the fiscal year were $37,524.00, all maintenance. The total expenditures were $33,595.66. Condition at end of fiscal year.-The existing project was com- pleted in December 1936. Concrete superstructure, 1,304 feet, on the detached breakwater, was completed in 1925, and on the en- trance piers in 1931. All structures 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 re- placed them with a steel-sheet pile bulkhead located landward of the former dock line. 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 23 to 16 feet. Between the Franklin Street Bridge and the turning basin at the head of the project, the depths vary from 18 to 3.4 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 depths in the turning basin at the head of the project vary from 1 to 2.6 feet. Available anchorage depths in the outer basin are 12 feet in the northerly portion and 8 feet in the southerly portion. Depths are based upon soundings taken during June 1944, October 1947, June 1948, and May 1950, and are referred to low-water datum. The mean water level in June 1950 was 1.06 feet above 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.

ARMY, 1950 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 session.). 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 existing 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, unencumbered 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 neces- sary alterations in other highway bridges across the Illinois Water- way, 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. 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. Doc. 126, 71st Cong., 2d sess.). 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 complete 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, Seventy-third Congress, second 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. RIVERS AND HARBORS-CHICAGO, ILL., DISTRICT 2105 The River and Harbor Act of July 24, 1946, supersedes the pro- visions of River and Harbor Act of March 2, 1945, and provides that local interests furnish free of cost to the United States all lands, easements and rights-of-way, and spoil-disposal areas neces- sary 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 rail- road bridges; and agree to remove at their own expense or satis- factorily alter the highway bridges across Des Plaines River at McDonough and Cass Streets (Joliet) and across the Chicago Sani- tary and Ship Canal at Sixteenth 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 provide near Clark Street, Gary, Ind., an adequate public barge-rail-truck terminal open to all on equal terms; and further provided that the several sections of the proposed channel may be improved as sep- arate units when considered advisable by the Secretary of the Army and the Chief of Engineers after local interests have pro- vided, 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 required between One Hundred Thirtieth and One Hundred Thirty-eighth Streets for the Calumet River lock site and appurtenances. Local cooperation required for the small boat harbor at Peoria, Illinois, authorized by the River and Harbor Act of July 24, 1946, has been fully complied with. Terminal facilities.-Of the 13 principal cities and towns along the Illinois River, about 5 own dock frontage, more or less im- proved for boat landings; 4 own dock frontage with no improve- ments; and 4 own no frontage except at street ends. At Peoria, the largest city on the river, there is a $400,000 modern river-rail municipal public terminal, having an available frontage of 1,100 feet; 205 feet are occupied by a dock house and 190 feet by an open dock. The dock house is served by a wharf boat 45 feet by 230 feet and an escalator capable of handling 1,000 tons a day. This terminal is served by the equivalent of a belt-line railroad. Grain elevators are available at 26 points between Graf- ton and Joliet. Private coal-loading terminals are located at Havana, Liverpool, and Copperas Creek. Coal-unloading terminals are located at Havana, at the mouth of the Vermilion River near La Salle, and at Joliet; and a cement-loading plant is located at Peru. Bulk-petroleum terminals are located at Havana, Kingston Mines, Peoria, Peru, Seneca, and Joliet. Sand and gravel plants are located at Kingston Lake, Chillicothe, Henry, Ottawa, Morris, Joliet, and Lockport. A barge-construction yard, launching ways, and shipyard are located at Seneca. 939127-51-vol. 2----43 2106 REPORT OF CHIEF OF ENGINEERS, U. S.

The locks and dams authorized by the act of July 3, 1930, have been completed and under present condi- tion of flow at Lockport there is now a channel 300 feet wide and 9 feet deep between Lockport and Utica, with the exception of the Marseilles Canal which is 200 feet wide. The two locks authorized by the act of August 30, 1935, have been completed, the old dams at Kampsville and LaGrange have been removed, and the 300- foot channel between Grafton and Utica has been completed. The three passing places in the Calumet-Sag Channel and dredging to widen the channel in the Calumet and Little Calumet Rivers are complete. A small-boat harbor has been provided at Peoria, Ill. A navigable channel now exists connecting the Mississippi River at Grafton with Lake Michigan via the Illinois and Des Plaines 2108 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Rivers, the Chicago Sanitary and Ship Canal, and the Chicago River, with a secondary outlet to Lake Michigan via the Calumet- Sag Channel and the Calumet and Little Calumet Rivers. The controlling depth of the river as it prevails, with a diversion of 1,500 cubic feet per second from Lake Michigan through the Chicago Sanitary and Ship Canal, is 9 feet during extreme low water. The limiting horizontal bridge clearance in the reach from Grafton to Utica is 114 feet. The limiting horizontal clear- ance which occurs at bridges between Utica and Lockport is 113 feet. The limiting horizontal clearance which occurs at bridges between Lockport and Lake Michigan via the Chicago Sanitary and Ship Canal and the Chicago River is 72 feet. The limiting horizontal clearance which occurs at bridges between Lockport and turning basin 5 in the Calumet River via the Chicago Sanitary and Ship Canal, the Calumet-Sag Channel, and the Calumet River, is 50 feet. Seven locks and six dams have been completed (see table under paragraph "Existing project" for description). The following work remains to be done: Preliminary surveys, planning, and designs; completion of construction of emergency lock and dam equipment; dredging to provide a channel 9 feet deep and 300 feet wide, with adequate widening at critical points and bends, to Lockport lock; improvement of the Calumet-Sag Channel as follows: (a) Replacement of the emergency dam in the Chicago Sanitary and Ship Canal; (b) enlargement of that canal to Sag Junction, and of the Calumet-Sag Channel, to afford channels 225 feet wide with usable depth of 9 feet; (c) construc- tion along the general route of Grand Calumet River of a channel with usable depth of 9 feet, 225 feet wide between Little Calumet River and the junction with the Indiana Harbor Canal and 160 feet wide thence to Clark Street, Gary, Ind., with a turning basin at Clark Street; (d) enlargement of the Indiana Harbor Canal to a width of 225 feet and usable depth of 9 feet between Grand Calumet River and the vicinity of One Hundred and Forty-first Street, inclusive; (e) removal of Blue Island lock and construction of a lock and control works in Calumet River near its head and of similar structures in the proposed Grand Calumet Channel west of the Indiana Harbor Canal; (f) alteration or elimination of railroad bridges across these channels lakeward of the Chicago Sanitary and Ship Canal, or the construction of new railroad bridges to provide suitable clearances, with apportionment of the costs between the bridge owners and the United States in accord- ance with the principles set forth in agreement dated February 23, 1945.

NOTE.-The limiting draft to the locks is determined by the depth over the breast walls. 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 op- erated 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. The Weitzel lock, destroyed in 1942 by excavation for the Mac- Arthur lock, was operated and maintained under the same appro- priation from September 1, 1881, to the end of the fiscal year 1935. In the following table are stated other characteristic features of the channel improvements belonging to the existing project. 2132 REPORT OF CHIEF OF ENGINEERS, U. S.

The project depths are referred to low-water datum for Lakes Superior and Huron, which are 601.6 and 578.5 feet 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 1950, is $92,228,- 100, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance, including $1,262,000 for operation and care of the locks, is $1,489,500. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2133 Acts Work authorized Documents July 11, 1870 Weitzel lock (replaced in 1943 by MacArthur lock), Report by Maj.

Local cooperation.-Fully complied with for all features of the project except for the removal of Bridge Island. For that feature, the owners of the International Bridge are required to provide a lift span over the South Canal upon request made by the Secretary of the Army and in accordance with plans, specifica- tions, and conditions approved by the Chief of Engineers, and the United States is to participate in the cost of the bridge change by payment to the owners of a percentage of the actual cost of the alteration, such percentage to be adjusted by the Chief of Engi- neers between 77.5 percent if a span for Cooper's E-50 loading is constructed and 84 percent if a span for E-35 loading is con- 2134 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 structed. On the basis of 1944 price levels the amount of the United States participation is estimated to be $562,000. Terminal facilities.-This improvement serves the through commerce between Lake Superior and the lower lakes, and it has not materially influenced the terminal facilities at the towns along its route which consist mainly of small docks for the accommoda- tion of local traffic. Several coaling docks for through-traffic ac- commodation have been established at Sault Ste. Marie, Lime Island, and Detour. Operationsand results during fiscal year.-New work: MacArthur Lock.-Government plant completed removal of material from a 10-foot strip along the south side of West Center Pier; 113 cubic yards, scow measure, of material being removed. Removal of bridge island from South Canal and new lift bridge. Hired labor work, making core borings to verify assumed foundation conditions at site of new bridge, completed. Construction of new powerhouse.-The correlation of manu- facturer's shop drawings with plans and specifications was con- tinued. Contract work for the manufacture of certain machinery for use in the powerhouse was continued and is nearly completed. Contract work for construction of hydroelectric power plant and appurtenant works is continuing; 45 percent of the work has been completed.

Special studies were continued in con- nection with the operation of the locks and construction therewith to insure the continuity thereof. Maintenance.-The U. S. dipper dredge Col. D. D. Gaillard dredged a portion of course 1, Bayfield Channel, to project depth of 26 feet, removing a total of 28,012 cubic yards of materials, scow measure. The U. S. derrick boats Merganser and No. 4 removed a total of 8,186 cubic yards of materials, scow measure, from east and west approaches to the locks, and from the channels in St. Marys River. Examination of existing channels by sounding and sweeping, and miscellaneous surveys, were continued. Auto- matic water level gages were maintained, lake level records were compiled, discharge through power plants, navigation canals, and compensating works was computed and tabulated. Operating and care-St. Marys Falls Canal.-The canal was opened to navigation 237 days, from July 1, 1949, to December 15, 1949, and from April 23, 1950, to June 30, 1950. During that period a total of 15,225 vessels, aggregating 79,209,553 tons of freight and 56,981 passengers, passed through the MacArthur, Poe, Davis and Sabin Locks in 11,356 lockages. The canal and locks were operated as required, and necessary repairs and improvements were made thereto and to the appur- tenant structures and equipment. Renewal of worn and damaged fenders, tar paving behind canal walls, maintenance and repair of electric light, power and telephone systems, buildings, grounds, piers and equipment continued. Installation of guard railings around gate recesses on Davis and Sabin Locks completed (hired labor). New pickup boom for handling emergency bulkhead pur- chased by contract.

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 year are subject to a consistent seasonal rise and fall, the lowest stages prevailing dur- ing the winter months and the highest during the summer months. 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 approved July 24, 1946, approved the modification of the project to provide for widening and deepening the Southeast Bend and improvement of the outlet of the North Channel, St. Clair River, in general accordance with the following descriptions: (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 estimate of cost for new work, revised in 1950, is $9,930,300 including $6,000,000 for construction of submerged sills. The latest (1946) approved estimate for annual cost of mainte- nance of dredged channels is $64,900, including $1,500 for mainte- nance in the outlet to North Channel. No expense or maintenance will probably be required for submerged sills. The existing project was authorized by the following river and harbor acts: 2140 REPORT OF CHIEF OF ENGINEERS, U. S.

Terminal facilities.-This improvement serves the through com- merce between the upper and lower lakes, and it has not materially influenced the terminal facilities at the towns along its route, which consist only of small docks for the accommodation of local traffic, with the exception of several privately owned coal terminals and on6 public terminal for general cargo, open to all vessels, at Port Huron, Mich. Operations and results during fiscal year.-Surveys were made over the shoals at Marine City, Russell Island, Channel East of Stag Island, and other miscellaneous areas at a cost of $26,677.23. Replacements and repairs to the control system and a continued investigation of the possible effects on water levels of the St. Clair River by commercial sand and gravel dredging were made at a cost of $5,305.55. The U. S. hopper dredge Savannah re- moved 45,888 cubic yards, bin measure, of shoaled material from the Southeast Bend during the period August 8-August 20, 1949, at a cost of $34,293.34. Prior to maintenance dredging sounding surveys were made over shoals at the head of Russell Island and Grande Pointe to Squirrel Island in June at a cost of $12,837.14. Costs during the year were $79,113.26, all for maintenance. Total expenditures were $80,146.44. Condition at end of fiscal year.-The existing project, exclusive of the compensating works, widening and deepening Southeast Bend, and improvement of the outlet of the North Channel, was completed in 1937.

Previous projects.-Authorized by River and Harbor Acts of August 30, 1852, March 2, 1867, and March 3, 1878. For further details see page 2882, Annual Report for 1896, and pages 1957- 1958, Annual Report for 1915, and page 1539, Annual Report for 1938. Existing project.-This provides for a channel 700 feet wide and 25 feet deep from the mouth of the south channel of the. St. Clair River to the open channel in Lake St. Clair. thence increasing 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 head of Detroit River; and for the construction of 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 mea- sured 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. Occasionally 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 1935, was $4,- 902,500, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $20,000.

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 level 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 1950, exclusive of amounts expended on previous projects, is $42,172,200. The latest (1950) approved estimate for annual cost of maintenance is $102,000.

For 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. Terminal facilities.-Within the limits of the port of Detroit are more than 8.4 linear miles of docks fronting on the river, and the appliances for handling freight are adequate. 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 two with ter- minal warehouses. Operations and results during fiscal year.-The U. S. derrick- boat Erie removed obstructions in the Amherstburg Channel to restore project depths of 21 feet at a cost of $41,214.90. Repairs were made to Sugar Island Compensating Dike by derrickboat Erie at a cost of $35,308.73. Examination of the improved chan- nels by sweeping and/or sounding was performed during the fiscal year at a cost of $43,649.40. Engineering surveys, investigations of strikings and groundings, repairs to the control system and extension of the harbor line system were made at a cost of $3,- 059.60. The U. S. hopper dredge Savannah removed 109,514 cubic yards, bin measure, of shoaled material from the lower section of the Livingstone Channel and channel east of Detroit River Light during the period August 22 to September 16, 1949, at a cost of RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2147 $34,363.06. A pollution study of the waters of the Detroit River in connection with dredging activities in the Rouge River was completed at a cost of $37.02. The total costs during the fiscal year were $157,632.71, all for maintenance. Total expenditures during the fiscal year were $164,102.76. Condition at end of fiscal year.-The existing project with the exception of the channel north of Belle Isle, deepening the westerly 300 feet of the Amherstburg Channel and the Ballards Reef Chan- nel (south of its junction with the Livingstone Channel), and extending the turning basin in Trenton Channel was completed in 1941. The work done consists of dredging, rock excavation, and the construction of dikes and compensating works. The dikes are generally in good condition. The Sugar Island compensating dike still shows signs of erosion and weathering.

CHEBOYGAN HARBOR, MICH. Location.-This harbor is located on the lower reach of the Cheboygan River and is about 100 miles distant from Alpena, Mich., in a northwesterly direction. The river, which is 51/2 miles long, has its source in Mullet Lake, from which it flows in a north- RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2149 erly direction, emptying into the Straits of Mackinac, Lake Huron. The improved portion is about 11/2 miles, in length. (See U. S. Lake Survey Chart No. 5.) Previous projects.-The original project was authorized by the River and Harbor Act of March 3, 1871, and modified by River and Harbor Act of June 14, 1880. For further details of previous proj- ects, see page 1956 of Annual Report for 1915, and page 1546 of Annual Report for 1938. Existing project.-This provides for a channel 21 feet deep and 200 feet wide from the 21-foot contour in Lake Huron to the outer end of the west pier, thence between lines parallel to and 25 feet from the docks, 21 feet deep, from this point to East First Street and 181/2 feet deep to the State Road bridge, and thence 81/2 feet deep and 60 feet wide from this bridge to the lock in the Cheboy- gan River, and for a turning basin 21 feet deep, 400 feet wide, and 420 to 770 feet long on the east side of the existing project chan- nel just below East First Street. The length of the section included in the project is about 12,000 feet, of which about 6,000 feet is in Lake Huron. The project depths are referred to low-water datum for Lake Huron, which is 578.5 feet above mean tide at New York. Each year the level of the river rises and falls about 3 feet. From day to day the level changes somewhat, due to wind and barometric pressure, such changes sometimes amounting to a foot or more. The estimate of cost for new work, revised in 1950, was $305,- 800, exclusive of amounts expended under previous projects. The latest (1950) approved estimate for annual cost of maintenance is $12,000. The existing project was adopted by the following river and harbor acts: Acts Work authorized Documents June 3, 1896 18Y-foot channel----------..- --- -------- _ Annual Report, 1895, p. 2823.

(Contains latest published maps) Local cooperation.-Fullycomplied with for completed portions of project. For modification approved May 17, 1950, responsible local interests are required to 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 the construction and subsequent maintenance of the project, when and as required; and (b) hold and save the United States free from damages due to the con- struction and subsequent maintenance of the works. Terminal facilities.-The harbor has one dock of about 1,000 feet length, which is privately owned but open to all vessels upon equal terms. There are also several other docks of less than 100 feet length which are privately owned and used. The facilities are considered adequate for existing commerce. 2150 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19 50 Operations and results during fiscal year.-Sounding surveys were made over the entire project in August 1949 and June 1950 at a cost of $2,500. Costs during the year were $2,500, all for maintenance. Total expenditures were $1,968.36. Condition at end of fiscal year.-The existing project with the exception of deepening the channel from the 21-foot contour in Lake Huron to East First Street and enlarging and deepening the turning basin was completed in 1939. The outer end of the old slab pier on the west side of the entrance was riprapped in 1921. Sounding surveys made in 1950 indicate that project depths of 18.5 feet are available from State Street bridge to Straits of Mackinac, except for shoals along the west channel line near the outer end of the west pier. Shoaling has reduced depths along the limits of the turning basin to about 12.5 feet. Above the State Street bridge a controlling depth of 5.5 feet, as indicated by an examination made in 1936, is available to the upper limit of the improvement, about 8,500 feet above the mouth of the river. Light- draft boats navigate a further distance of 30 miles in a waterway improved by local interests under a state law. The costs have been $112,681.82 for new work and $94,340.13 for maintenance, a total of $207,021.95. The expenditures have been $206,490.31. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $531.64 plus an anticipated allotment of $39,000 during fiscal year 1951, a total of $39,531.64, will be applied as follows: Accounts payable June 30, 1950 ............................. $531.64 Maintenance: Maintenance dredging northeast corner of turning basin by U.

HAMMOND BAY HARBOR, MICH. Location.-This harbor is located on the northwest shore of Lake Huron, about 20 miles southeast of Cheboygan, Mich. (See U. S. Lake Survey Chart No. 5.) Existing project.-This provides for the formation of a harbor of refuge, protected by breakwater structures extending to the 12-foot depth contour in the lake, for dredging a harbor basin to a depth of 10 feet, and for dredging an entrance channel to a depth of 12 feet. The project depths are referred to low-water datum for Lake Huron, which is 578.5 feet above mean tide at New York. The estimate of cost for new work, made in 1950, is $625,600 excluding $89,400 to be contributed by local interests. The latest (1945) approved estimate of annual cost of maintenance is $750. The existing project was authorized by the River and Harbor Act approved March 2, 1945. For latest published maps see House Document No. 446, Seventy-eighth Congress, second session. Local cooperation.-The improvement authorized by the act of March 2, 1945, is subject to the condition that responsible local agencies give assurances satisfactory to the Secretary of the Army that they will- (1) Contribute $89,400 in cash toward the first cost of protec- tive structures and dredging. (2) 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 accommodation of transient vessels. (3) Establish a competent and properly constituted public body, empowered to regulate the use, growth, and free development of harbor facilities, with the understanding that harbor facilities shall be open to all on equal and reasonable terms. (4) Hold and save the United States free from damages due to construction and maintenance of the works. (5) Provide, without cost to the United States, all lands, ease- ments, and rights-of-way necessary for the construction of the project, including suitable spoil disposal areas when and as re- quired. 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: Harrisville, Mich.; and Au Sable River (Oscoda), Mich. These assurances were furnished by the Michigan State Water- ways Commission and were approved by the Assistant Secretary of the Army on March 22, 1948. Terminal facilities.-The two small, privately owned, timber wharves are used principally as fishing terminals by the owners. Two rock-filled, timber crib piers, extending lakeward from the Coast Guard station for a distance of about 200 feet, are used by that service. Terminal facilities are considered adequate for exist- ing commerce. 2152 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Operations and results during fiscal year.-By contract with the University of Michigan, a series of model studies were made to determine the best location and arrangement of breakwaters for the proposed harbor of refuge.

Previous projects.-Authorized by River and Harbor Acts of August 14, 1876, and August 2, 1882. For further details see page 1957 of Annual Report for 1915 and page 1548 of Annual Report for 1938. Existing project.-This provides for a channel 21 feet deep, from that depth in Thunder Bay to a point 2,500 feet lakeward of the lighthouse; thence 181/2 feet deep to the upper end of the Fletcher Paper Co. dock in Thunder Bay River; for channel width of 200 feet from the 21-foot contour in Thunder Bay to the outer end of the breakwater, thence tapering to 100 feet in a distance of about 500 feet, thence 100 feet to Second Avenue Bridge and thence 75 feet for 1,600 feet, to upper limit of the improvement; and dredging a turning basin opposite the Fletcher Paper Co. dock 15 feet deep and about 160,000 square feet in area; for the protection of the channel on the south side by the construction of a rubble mound over a length of about 600 linear feet landward RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2153 from the end of the old docks and by the construction of a rubble breakwater from the same point lakeward for a distance of about 370 feet. The total length of the river included in the project is 4,620 feet, and the improved channel extends 7,500 feet farther into the bay beyond the lighthouse. The project depth is referred to low-water datum for Lake Huron, which is 578.5 feet above mean tide at New York. Each year the level of Thunder Bay River rises and falls about 31/ feet. From day to day level changes somewhat due to wind and baro- metric pressure, such changes frequently amounting to more than a foot. The estimate of cost for new work, revised in 1935, was $340,- 000, exclusive of amounts expended on previous projects. The latest (1935) approved estimate for annual cost of maintenance is $7,500.

SAGINAW RIVER, MICH. Location.-This river is formed by the union of the Tittaba- wassee and Shiawassee Rivers, is about 22 miles long, and flows in a northerly direction and into the south end of Saginaw Bay, Lake Huron. (See U. S. Lake Survey Chart No. 5.) Previous projects.-Authorized by River and Harbor Acts of June 23, 1866, June 23, 1874, June 18, 1878, March 3, 1879, August 2, 1882, and August 5, 1886. For further details see page 1957 of Annual Report for 1915, and page 1550 of Annual Report for 1938. Existing project.-This provides for a channel 21 feet deep and RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2159 200 feet wide from deep water in Saginaw Bay to the Detroit & Mackinac Railway bridge in Bay City, thence 20 feet deep to the Sixth Street Bridge in Saginaw, Mich., thence 161/2 feet deep to the junction with the Tittabawassee River, a distance of about 291/2 miles; and for a turning basin 15 feet deep by 360 feet wide, varying from 690 feet to 420 feet in length, adjacent to the east side of the existing channel between Court Street and Bristol Street Bridges. The project depth is referred to low-water datum for Lake Huron, which is taken at 578.5 feet above mean tide level 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 few hours, resulting from the raising or lowering of Saginaw Bay by violent winds. The estimate of cost for new work, revised in 1938, is $2,657,500, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $97,500.

Local cooperation.-Fully complied with. Terminal facilities.-Generalutility docks, and seven docks han- dling petroleum products, all privately owned, are located at Es- sexville and Bay City. The aggregate length of these docks is about 3,000 feet. Similar docks with a total length of about 1,500 feet are located in the upper river at Saginaw. In addition, the Chevro- let Motor Co. operates an industrial dock about 600 feet long and the Saginaw Dock & Terminal Co. operates a private dock about 900 feet long at Saginaw, and the Consumers Power Co. owns and operates a dock about 1,100 feet long at Zilwaukee. Turning basins have been constructed by the owners opposite the latter two docks. These terminal facilities are adequate for the existing commerce. Operations and results during fiscal year.-Repairs and replace- ments to the control system and preparation of control drawings, including miscellaneous surveys, were made at a cost of $7,639.85. Maintenance dredging by contract was performed in the bay sec- tion, 436,198 cubic yards being removed during the period July 1- November 15, 1949, at a total cost of $267,795.46. The U.

HARBOR OF REFUGE AT HARBOR BEACH, LAKE HURON, MICH. Location.-This harbor is located on the west shore of Lake Huron about 60 miles north of Port Huron, Mich. (See U. S. Lake Survey Chart No. 5.) Existing project.-This provides for the formation of a harbor of refuge, protected by stone-filled timber-crib breakwaters-the main breakwater being 4,716 feet long, the north one 1,204 feet long, the original north entrance, 304 feet wide, being reopened to a depth of 10 feet, and the south breakwater 1,956 feet long; for dredging the main entrance, 600 feet wide, to a depth of 23 feet; and for dredging an anchorage area approximately 3,000 feet long by 1,200 feet wide to a depth of 21 feet. The project depths are referred to a stage of 578.5 feet above mean tide at New York. The normal elevation of the water sur- face in Lake Huron varies from year to year. During each year the level is subject to a seasonal rise and fall, the lowest stages prevailing during winter and the highest during summer months. Such yearly changes, measured by monthly mean levels, may be as much as 2.21 feet. Since 1875 the difference between the highest and lowest monthly mean level during the navigation season has been about 5 feet. Occasional fluctuations due to winds of high velocity and variations in barometric pressure may amount to sev- eral feet in a few hours. The estimate of cost for new work, revised in 1917, is $1,658,- 550. The latest (1950) approved estimate for annual cost of main- tenance is $10,000.

Jan. 21, 1927 Removal of portion of breakwater in the interest of sanitation. Local cooperation.-None required. Terminal facilities.-There is but one dock about 500 feet long. This dock, privately owned, is open to all vessels upon equal terms and is considered adequate for existing commerce. Operations and results during fiscal year.-For completion of the fendering on the main breakwater, the costs were $10,410.77 and the expenditures $12,740.64. Condition at end of fiscal year.-The existing project was com- pleted in 1928. The work consisted in the construction of three breakwaters, the dredging of an entrance channel, and the dredg- ing of an anchorage area about 72 acres in extent under the pro- tection of the breakwaters. The breakwaters were originally constructed in 1885, and since that time it has been necessary to top them with concrete and to protect about 6,170 feet of the outer face with heavy riprap. The north entrance was closed by rubble mound in 1920 and reopened to about 10-foot depth in 1928. Dredging was completed in 1922. 2164 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The. harbor has controlling depths of 20.5 feet at its entrance and about 18 feet within the anchorage area, as shown by survey of 1945. The breakwaters are in fair condition, except that riprap along the lake face of the main breakwater needs repair. Fender- ing on the main breakwater was replaced in 1950. The costs have been $1,200,598.17 for new work and $1,495,- 780.65 for maintenance, a total of $2,696,378.82. Total expendi- tures have been $2,696,378.82.

These assurances were furnished by the Michigan State Water- ways Commission and were approved by the Assistant Secretary of the Army on March 22, 1948. To date the Michigan State Waterways Commission has contributed funds in the amount of $101,850; and has stated that the balance, $28,250, will be avail- able in fiscal year 1951. Terminal facilities. One small privately owned stone filled tim- ber crib dock is used principally as a fishing terminal by the owner. A municipally owned, timber pier, extending about 400 feet lake- ward, is open to all vessels upon equal terms. About 200 feet of this pier will require removal under the present project. Terminal facilities are considered adequate for existing commerce. Operations and results during fiscal year.-Advance planning was continued at a cost of $11,728.66, and a contract was awarded April 6, 1950, for the construction of north and south cellular type steel sheet piling breakwaters with steel sheet piling single wall extensions at the shore ends thereof, and for dredging a har- bor basin and entrance channel. 5,675 square feet of single wall steel sheet piling has been delivered and partially placed in the work. 79,694 square feet of cellular wall steel sheet piling has been delivered and partially placed in the work. Cell fill material in the amount of 6,950 cubic yards has been placed, at a total cost of $185,537.50. Total costs during the fiscal year were $197,266.16, all for new work. Total expenditures were $57,062.76. Condition at end of fiscal year.-The project is about 32 per- cent completed. Work remaining to be done consists of completing the construction of the north and south breakwaters with shore- ward extensions and dredging the harbor basin and entrance chan- nel.

BLACK RIVER, MICH. Location.-This river has its source in the northern part of Sanilac County, Mich., is about 60 miles long, and flows in a south- easterly direction into the. St. Clair River. (See U. S. Lake Survey Chart No. 43.) Previous projects.-Authorized by River and Harbor Acts of June 10, 1872, and August 11, 1888. For further details see page 1441 of Annual Report for 1916, and 1554 of Annual Report for 1938. RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2167 Existing project. This provides for a channel 20 feet deep from deep water in St. Clair River to the Grand Trunk Western Rail- road bridge, 160 feet wide at the mouth, decreasing to 100 feet about 800 feet from the mouth, thence 100 feet wide for 2,600 feet, decreasing to 75 feet for a distance of 4,800 feet at upper end; widening two bends to 100 feet, one at the foot of Twelfth Street, and the other below the Grand Trunk Western Railroad bridge; and for a settling basin 75 feet wide and 20 feet deep, beginning at the Grand Trunk Western Railroad bridge in Port Huron and extending upstream a distance of about 2,300 feet. The length of the section included in the project is 10,500 feet. The project depth is referred to local low-water datum in the St. Clair River at the mouth of the Black River, which is 577.5 feet above mean tide at New York. Each year the level of the river rises and falls from 4 to 6 feet, due to the fact that spring freshets raise the level considerably above the normal. The level also changes from day to day, due to winds, such changes amounting to several inches. The estimate of cost for new work, revised in 1950, is $194,500, exclusive of $140,000 to be contributed by local interests, and exclusive of cost of work on previous projects. The latest (1950) approved estimate of annual cost of maintenance is $13,400.

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/ miles via the Short Cut Canal, and about 4 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 dur- ing 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 1950, is $1,118,- 200, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $90,000.

Local cooperation.-The act approved August 30, 1935, provided that no Federal expenditures should be made on the improvements in the old channel until local interests had provided, without cost to the United States, all necessary rights-of-way and had furnished guaranties, satisfactory to the Secretary of the Army, protecting the United States against all damages to adjacent lands and property which may result from dredging operations. Except for the guaranties protecting the United States against damages to adjacent lands and property along the 25-foot channel, this re- quirement has not been complied with. All prior requirements fully complied with. Terminal facilities.-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 improvement, with improved type of unloaders. Eight docks fully equipped, for handling oil and oil products, also one dock equipped for handling gypsum rock, have, been constructed along the river bank. These docks have good railroad connections. In addition there are 4 docks owned by sand and gravel companies which have unloading machinery, one pulpwood dock, and two timber docks. There are also a number of smaller docks for launches. All docks along the river are privately owner and understood to be restricted to use of the owners. These facilities are considered adequate for exist- ing commerce. Operations and results during fiscal year.-The U. S. hopper dredge Savannah performed maintenance dredging over the entire project during the period December 14, 1949-February 24, 1950, removing material in the amount of 252,848 cubic yards, bin measure, at a cost of $77,942.68. Dredging surveys, including necessary control replacement, were made over the entire project at a cost of $2,340.27. Costs were reduced by $5,103.76 during fiscal year in connection with an attempt to collect costs from Ford Motor Company covering removal of shoal from channel by U. S. derrickboat Erie during fiscal year 1949. The costs were $75,179.19, all for maintenance. The exenditures were $80,525.40. Condition at end of fiscal year.-The 21-foot project via the Short Cut Canal to the upper limit of improvement was completed in 1923. The work consisted of dredging and the construction of five dolphins at the mouth of the Short Cut Canal. Contract work on the 25-foot project at the mouth of the river in the Old Channel RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2171 was performed with funds allotted from the Emergency Relief Administration. Due to the shortage of funds, contract operations were restricted to a distance of 1,150 feet upstream from 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 in the 21-foot project is 21 feet for a minimum width of 125 feet over the center section of the Short Cut Canal and river to the turning basin with depths of 21 feet generally in the turning basin, with the exception of shoal areas along the channel banks. The controlling depth in the old channel from its junction with the Short Cut Canal to the 25-foot section is 17 feet. The 25-foot section has project depths along the Hanna Furnace Co. dock. All the bridges have been altered in accordance with the require- ments of law. The turning basin at the head of the project has been completed. The dolphins at the mouth of the Short Cut Canal are in poor condition, and as they are no longer utilized by naviga- tion interests further maintenance is not considered justified and the dolphins should be removed. The head of navigation is deter- mined by a fixed bridge about 2,600 feet above the upper limit of improvement.

MONROE HARBOR, MICH. Location. -The harbor is located on the lower reach of the Raisin River, which empties into Lake Erie at Monroe, Mich. (See U. S. 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 width 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 riprapped protecting dikes on each side of the channel ex- tending lakeward for a distance of about 1,200 feet; 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 greateset 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 estimate of cost for new work, revised in 1945, is $777,500, excluding $300,000 contributed by local interests. The latest (1930) approved estimate for annual cost of maintenance is $35,000.

Terminal facilities.-At the city of Monroe are some small privately owned docks and a municipally owned terminal. These docks are open to' all vessels upon equal terms. The Kelsey-Hayes Wheel Company of America has its own private dock. The facili- ties. are considered adequate for existing commerce. Operations and results during fiscal year.-The U. S. hopper dredge Savannah operated over the entire project (except the 9- foot portion which is not maintained) during the period Septem- ber 17 to October 13, 1949, material in the amount of 101,282 cubic yards, bin measure, being removed at a cost of $34,476.74. Dredg- ing surveys were made in July 1949 and June 1950 at a cost of $2,583.77. The costs were $37,060.51 and expenditures were $36,- 523.61 for maintenance, including $7,500 contributed funds. Condition at end of fiscal year.-The existing project was com- pleted in 1936 except for riprapping of protecting dikes on each side of the channel, which is not considered necessary at the present time in the interest of navigation. Due to the combined action of severe storms and continued high water, the dikes have largely disappeared. An after dredging survey made in October 1949 indicates controlling depths as follows: 17.5 feet from deep water in Lake Erie to the lower end of the turning basin, thence 8 feet to the upper end of the 21-foot project, and 11 feet in the turning basin, except for a few small isolated shoals.

TOLEDO HARBOR, OHIO. Location.-This harbor comprises the lower 7 miles of Maumee River and the channel about 16.5 miles through Maumee Bay to Lake Erie. The Maumee River has its source in Northern In- diana and empties into Lake Erie. The harbor is located at the westerly end of Lake Erie, 99 miles westerly from Cleveland, Ohio. (See U. S. Lake Survey Chart No. 3.) Previous projects. Adopted by River and 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. RIVERS AND HARBORS--DETROIT, MICH., DISTRICT 2175 Existing project.-This provides for a channel 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 and Ohio Railway dock, 3,055 feet in length, 460 feet maximum width and 16.2 acres in area; and for a stone-revetted earth dike, 1,000 feet long, to form a foundation for range lights in Maumee Bay. The projects 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 1950, is $5,482,400 exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $354,000. The existing project was adopted by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1899 Auxiliary channel above Fassett St. Bridge, and the H.

Recommended modification of project.-On April 28, 1950, the Chief of Engineers recommended modification of the existing project for Toledo Harbor, Ohio, to provide for removal of the center dike on which the Maumee Bay Range Lights are located, to the project depth of 25 feet, generally in accordance with the plans of the district engineer and with such modifications thereof as in the discretion of the Chief of Engineers may be advisable, at an estimated cost to the United States of $420,000 for the removal of the dike and a reduction of $3,000 in the cost of Annual main- tenance, subject to the provision that local interests hold and save the United States free from damage due to the construction works. Local cooperation.-Fullycomplied with for completed portions of project. For widening at bend opposite C. & O. dock, approved May 17, 1950, local interests are required to agree to hold and save the United States free from damages resulting from the con- struction works. Terminal facilities.-The city of Toledo has provided a lagoon near the mouth of the river suitable for the winter mooring of 2176 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 vessels. Three large railroad terminals for the handling of ore and four for coal are open to shippers for these commodities; one fuel dock and three docks with elevator facilities for handling grain. Three pipe-line docks for shipment of oil, one pipe-line dock for receipt of gasoline, and three fish docks are private. Two package-freight terminals are open to all vessels on equal terms. Considerable wharf frontage is owned by railroads, which is avail- able for the transshipment of miscellaneous cargoes, such as lum- ber, etc., to and from cars. Of 10 sand and gravel docks, 2 are for public use. Four docks at street ends are owned by the city of Toledo, at which freight may be loaded or unloaded free of charge, no storage being allowed. Terminal facilities are regarded as ade- quate for existing commerce. Operations and results during fiscal year.-The U. S. hopper dredges Hains, Hofman, and Savannah operated over the entire project during the periods from July 28 to October 20, from July 1 to November 27, and from October 14 to December 13, 1949, re- moving materials in the amounts of 476,144 cubic yards, 739,753 cubic yards and 184,628 cubic yards, bin measure; the costs were $134,014.44, $188,193.96 and $75,359.08, respectively. Dredging surveys were made in July 1949 and May and June 1950 over the entire project at a cost of $10,816.86 A field office was maintained for supervision of the harbor and miscellaneous surveys and in- spections at a cost of $7,903.86. The costs were $416,288.20 for maintenance and the expenditures $420,772.84. Condition at end of fiscal year.-The existing project, exclusive of widening the channel opposite the Chesapeake and Ohio Rail- way Dock, was completed in 1936. Maintenance dredging has restored project depths over the center 350 feet of the lake sec- tion and in the river channel with about 161/2 feet available in the turning basin. Continuous heavy shoaling usually results in a controlling depth of about 23 feet over the bay section by the close of the season.

PUT-IN-BAY HARBOR, OHIO Location. This harbor is located on the north side of South Bass Island, in Lake Erie, about 38 miles east of Toledo, Ohio. (See United States Lake Survey Chart No. 3.) Existing project.-This provides for a channel of varying width, not exceeding 225 feet, and 14 feet deep from that depth in the lake to a point 150 feet west of the Fox wharf; thence 100 feet wide and 8 feet deep along the harbor frontage to the vicinity of Miller's wharf, a further distance of 1,600 feet, provided that no dredging shall be done by the United States closer than 25 feet to existing structures. The project depth is referred to low-water datum for Lake Erie, which is taken at 570.5 feet above mean tide at New York. Ordi- nary fluctuations of water level are from 1.3 feet above to 2 feet below low-water datum and extreme fluctuations produced by wind and other causes are from 6 feet above to 2.5 feet below that plane, The estimate of cost for new work, made in 1937, is $50,000, with $500 annually for maintenance. . . 2178 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The existing project was authorized by the River and Harbor Act of August 26, 1937 (H. Doc. 132, 75th Cong., 1st sess.). The project document contains the latest published map. Local cooperation.-None required. Terminal facilities.-There are 25 docks in existence at this lo- cality; 3 of these docks are commercial wharves, the others being used for tying small pleasure craft, commercial livery boats, and commercial fishing boats. The Fox dock and the Dollar dock are used by vessels carrying passengers and small package freight, while the Dodge dock is used for receipt of coal brought in by barges. None of the wharves has any mechanical equipment for handling freight. All of the docks, except one, are privately owned and are open to all vessels upon equal terms. The facilities are adequate for existing commerce. Operationsand results during fiscal year.-None. Condition at end of fiscal year.-The existing project was com- pleted in 1939. The sounding survey of July 1948 indicates that full project depths are available over the entire project. The costs and expenditures have been $51,746.56 for new work and $1,000 for maintenance, a total of $52,746.56. Proposed operations.-No work is proposed during fiscal years 1951 and 1952.

PORT CLINTON HARBOR, OHIO Location.-Port Clinton Harbor comprises the lower half mile of the Portage River, which empties into Lake Erie at a point 72 miles westerly from Cleveland, Ohio. It is from 200 to 300 feet wide. (See U. S. Lake Survey Chart No. 3.) Existing project.-This provides for parallel stone and pile jet- ties at the mouth of the river, the east jetty 2,200 feet long and the west jetty 1,980 feet long, extending to the 10-foot contour in the lake, and for dredging a channel to a depth of 10 feet and 100 feet wide, widening at the bridge to 200 feet for a length of 800 feet, the length of the channel to be 5,000 feet, extending from 2,100 feet outside the jetties up to the highway bridge. The project depth is referred to low-water datum for Lake Erie, which is 570.5 feet above mean tide at New York. Ordinary fluc- tuations of water level are from 3 feet above to 2 feet below low- RIVERS AND HARBORS-DETROIT, MICH., DISTRICT 2179 water datum, and extreme fluctuations produced by wind and other causes are from 6.5 feet above to3 feet below that plane. The estimate of cost for new work, revised in 1883, is $90,000. The latest (1950) approved estimate for annual cost of mainte- nance is $5,000. The existing project was adopted by the River and Harbor Act of June 10, 1872 (Annual Report for 1875, p. 295). For latest published map, see House Document No. 815, Sixty-first Congress, second session. Local cooperation.-None required. Terminal facilities.-There are five private docks and one pub- lic fish dock, one private sand dock, and one public fueling dock which is also used as a private lumber and cargo coal terminal. One dock, at the foot of Madison Avenue, is owned by the village of Port Clinton and s open to the public. One shipyard does some business in the building of small boats and launches. Terminal facilities are regarded as adequate for the needs of existing com- merce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The existing project was com- pleted in 1893. The work done consisted of two jetties, completed in 1893, and in dredging a channel from the lake to the highway bridge, completed in 1893. Project dimensions are available over the entire project with the exception of a small shoal about 2,000 feet lakeward of the end of the jetties. The minimum available depth here is 91/2 feet over the entire width of the channel for a distance of about 500 feet. Both jetties are now in good condition. The head of navigation for light-draft boats is about 12 miles above the mouth of the river.

SEBEWAING, SEBEWAING RIVER, MICH. Location.-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 discharges into Saginaw Bay, an arm of Lake Huron, about 20 miles north- east of the mouth of Saginaw River. (See U. S. Lake Survey Chart No. 5.) FLOOD CONTROL-DETROIT, MICH., DISTRICT 2188 Existing project.-T--his 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 existing project was authorized by the Flood Control Act approved August 18, 1941. (See H. Doc. 286, 76th Cong., 1st sess., which contains the latest published maps.) The estimated (1949) cost of construction is $380,500. The ap- proved estimate (1949) for annual cost of maintenance is $5,000. Local cooperation.-With the exception of the furnishing of lands, easements, and rights of way for the removal of the re- maining portion of the dike on the south side of the channel lake- ward of the railroad bridge, all requirements of local cooperation have been complied with. Operations and results during fiscal year.-Sounding surveys were made in July 1949 and June 1950 at a cost of $1,584.47 and the stream gaging program continued at a cost of $790. Repairs to the stop logs for the gates installed at fish houses were made at a cost of $319.38. Ice jams were removed in March 1950 to allevi- ate spring flood conditions at a cost of $971.55. Total costs during the fiscal year were $3,665.40 and expenditures were $2,997.83, all for maintenance. Condition at end of fiscal year.-The work required to construct the project is 95 per cent complete. Work remaining to be done consists of completion of removal of dike on south side of channel lakeward of railroad bridge. Work was started in May 1947 and brought to its present state of completion iniJuly 1948. The project is in operation. All items of the project are in good condition ex- cept that the channel shows signs of shoaling at the upper end and there has been some erosion of the banks. The costs have been as follows: New work ....................................... $365,642.14 Maintenance .............................................. 5,225.56 Total ............................................ 370,867.70 The expenditures have been $370,200.13.

MOUNT CLEMENS, CLINTON RIVER, MICH. Location.-Clinton River drains an area of about 760 square miles in Macomb, Oakland, St. Clair, and Lapeer Counties in the southeastern portion of the Lower Peninsula of Michigan and dis- charges into Anchor Bay, an arm of Lake St. Clair, about 18 miles north of the head of Detroit River. (See U. S. Lake Survey Chart No. 42.) Existing project.-This provides for construction of a cut-off canal extending from a point on Clinton River, at the southerly limit of Mount Clemens, Mich., and about 1,500 feet below Gratiot Avenue Bridge, directly southeastward to Lake St. Clair, a dis- tance of about 12,500 feet, with the. bottom width varying from 50 to 80 feet and with a control weir at the upper end of the cut-off canal. The plan of improvement will provide protection to Mount Cle- mens and Harrison Township from floods with a magnitude of 15,000 cubic feet per second. The existing project was authorized by the Flood Control Act approved July 24, 1946. (See H. Doc. 694, 79th Cong., 2d sess., which contains the latest published maps.) The estimate of Federal cost for new work, revised in 1950, is $980,000. The estimated cost to local interests is $1,191,300. FLOOD CONTROL-DETROIT, MICH., DISTRICT 2185 Local cooperation.-The improvement is subject to the condi- tion that responsible local interests give assurances satisfactory to the Secretary of Army that they will- (1) Provide without cost to the United States all lands, ease- ments, and rights-of-way, including the removal of buildings, nec- essary for the construction of the project. (2) Hold and save the United States free from damages due to the construction works. (3) Bear the cost of all necessary highway bridges and access roads thereto. (4) Establish and enforce regulations satisfactory to the Sec- retary of Army and designed to prevent encroachments on the improved and existing channels.

RENO BEACH-HOWARD FARMS AREA, LUCAS COUNTY, OHIO Location.-The Reno Beach-Howard Farms area comprises 2,120 acres of land located on the south shore of Lake Erie, about 15 miles east of Toledo, Ohio. The area lies between the mouth of Cooley Creek on the west and Wards Canal on the east, and has a lake frontage of 15,400 feet. Existing project.-This provides for (plan "A") the construc- tion of 8,200 lineal feet of roadway sea wall, consisting of a earth dike, faced on the lakeward side with a quarry-run stone fill; and for a steel sheet pile floodwall connecting the easterly end of the sea wall at Wards Canal to the existing inland dike parelleling the canal. However, provision is made that, if local interests pay the dif- ference in cost, a more costly plan of improvement (plan "B") may be substituted for the project described above, at the time of construction. This alternate project would provide for the con- struction of an earth dike; for a protecting bulkhead on the lake- ward side of the dike, constructed of steel sheet piling; for steel sheet pile groins along that bulkhead and for a steel sheet pile bulkhead connecting the end of the bulkhead of the shore dike at Wards Canal to the existing inland dike paralleling the canal. The plan of improvement will prevent flood damage resulting from windstorms and high stages of water on Lake Erie and will enhance land values. In addition the proposed improvement will add materially to recreational facilities and increase the social security of the inhabitants. The existing project was approved by the Flood Control Act approved June 30, 1948. (See H. Doc. 554, 80th Cong., 2d sess., which contains the latest published maps.) The estimate of Federal cost for new work (1950) for plan "A" is $365,200. The estimated cost to local interests is $116,400. Local cooperation.-The improvement (plan "A") is subject to the condition that no funds shall be expended by the United States until local interests have contributed one-fourth of the total cost of construction and have given assurances satisfactory to the Sec- ,retary of the Army that they will- 2190 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 (1) Provide without cost to the United States all lands, ease- ments, rights-of-way and borrow areas necessary for the con- struction of the project, and make all necessary bridge alterations and provides access to all public bathing beaches at their own expense. (2) Hold and save the United States free from damages due to the construction works. (3) Maintain the entire protective works after completion, in- cluding the existing jetties on the east side of Cooley Creek and on the west side of Wards Canal, the bathing beaches and their protective structures, and a sufficient outlet in Wards Canal to carry the free flow into Lake Erie at all times, all in accordance with regulations prescribed by the Secretary of the Army. The improvement (plant "B") is subject further to the condi- tion that, if at the time of construction local interests desire con- struction of plan "B", that plan may be substituted for plan "A". subject to the same conditions of local cooperation as prescribed for plan "A" and in addition to the condition that local interests make a further cash contribution toward the cost of construction equal to the difference in the cost at the time of construction be- tween plan "B" and plan "A". Local interests have signfied their willingness to cooperate in the plan of improvement. Operations and results during fiscal year.-The preparation of definite project plans was initiated at a cost of $3,438.22. Condition at end of fiscal year.-No construction work has been done. Costs were $3,488.22 and expenditures were $3,317.34, all for new work.

SANDUSKY HARBOR, OHIO Location.-This harbor is located in the southeasterly portion of Sandusky Bay, 55 miles westerly from Cleveland, Ohio. (See U. S. Lake Survey Chart No. 365.) Previous projects.--Adopted by River and Harbor Acts of June 11, 1844; June 23, 1866; March 3, 1873; July 5, 1884; August 11, 1888; and August 18, 1894. For further details, see page 1960 of Annual Report for 1915, and page 1574 of Annual Report for 1938. Existing project.-This provides for the following: (a) An outer channel 400 feet wide and 21 feet deep from deep water in Lake Erie through Sandusky Bay, a distance of about 31/2 miles, to the city water-front docks. (b) A channel along the water front about 7,800 feet long, 300 feet wide, and 22 feet deep ending in a turning basin generally 800 feet wide and 22 feet deep, and a dike constructed with the ex- cavated rock on the north side of the channel and basin. (c) Maintaining a channel to a depth of 22 feet from the turn- ing basin northward about 3,540 feet, that portion opposite the Pennsylvania Railroad coal wharf to a width of 350 feet, and north thereof to a width of 400 feet; thence 300 feet wide northeastward through Sandusky Bay about 7,700 feet, to a junction with the straight channel; no dredging to be done within 50 feet of the face of the wharf. (d) Protection works consisting of a stone jetty on the easterly side of the channel, extending northeasterly from Cedar Point, a distance of 6,000 feet, with suitable pierhead; a short stone spur at Cedar Point ;and revetment of the slope adjacent to the channel in the vicinity of the inner front light with a brush-and-stone mattress. The project depth is referred to low-water datum for Lake Erie, which is 570.5 feet above mean tide at New York. Ordinary fluc- tuations of water level are from 3.5 feet above to 0.5 foot below low-water datum, and extreme fluctuations, produced by wind and other causes, are from 6 feet above to 2.5 feet below that plane. The estimate of cost for new work, revised in 1935, was $2,690,- 000 (including $275,000 contributed by local interests), exclusive of amounts expended on previous projects. The latest (1948) approved estimate of annual cost of maintenance is $92,000. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-BUFFALO, N.

Local cooperation.-Fully complied with. Terminal facilities.-There is an extensive coal terminal, con- sisting of three docks, adjacent to the turning basin at the west- erly end of the dock channel open to shippers of coal. Located on the dock channel are 10 private terminals for the handling of sand and gravel, fish, miscellaneous freight, and passengers. The city of Sandusky owns a pier and two small boat basins. A yacht-club dock and several other privately owned servicing and storage docks are for recreational and other small craft. Two docks for passenger boats are located at Cedar Point. The facilities are con- sidered adequate for the existing commerce. (See Lake Series No. 8, revised 1939, Corps of Engineers.) Operations and results during fiscal year.-Government plant and hired labor removed 255,749 cubic yards of material for res- toration of project depth in the straight, bay, and outer bar chan- nels at a cost of $65,586.87 for maintenance. The expenditures were $65,586.87. Condition at end of fiscal year.-The existing project was com- pleted in 1935. The protecting works are generally in poor condi- tion. The east jetty has settled from its original elevation of 4.3 feet to about 1 or 2 feet above low-water datum and in some places has settled to below low-water datum. The stone in the dike has disintegrated and settled. In many places the dike is down to low- water datum. The controlling depth in the straight, outer bar, and bay channels is 21 feet and in the dock channel and turning basin 20 feet at low-water datum. The total costs and expenditures of the existing project were $3,678,333.77, of which $2,597,258.21, including $599,500 Public Works funds, was for new work and $1,081,075.56 for mainte- nance.

Local cooperation.-Dredgingof 20-foot turning basin is sub- ject to the provision that local interests furnish without cost to the United States necessary lands, easements, and rights-of-way and spoil disposal areas for new work and maintenance when and as required, and hold and save the United States free from all claims for damages incident to the construction and subsequent maintenance of the improvement. These conditions have not been complied with, however, local interests have furnished assurances that they will provide without cost to the United States the necessary lands, easements and rights-of-way. Prior conditions have been complied with. Terminal facilities.-One iron ore terminal, and one coal dock are open to the public. Extensive docks of the National Tube Co. handle iron ore, limestone, pig iron, fuel oil, and sand, and are not open to the public. Two sand and four fish docks are privately owned. The American Shipbuilding Co. has drydocks and facili- ties for building and repairing the largest lake vessels. A yacht- club dock and several other privately owned servicing and storage docks are for recreational and other small craft. The city of Lorain owns two docks without rail connections which are open to the public. The facilities are regarded as adequate for existing com- merce. (See Lake Series No. 8, revised 1939, Corps of Engineers.) Operations and results during fiscal year.--Government plant and hired labor removed 446,306 cubic yards of material for the restoration of project depth in the outer harbor and river channel at a cost of $135,454.35 and made repairs to the east breakwater at a cost of $3,025.88. 'Thetotal cost for the year was $138,480.23 for maintenance. The total expenditures were $135,863.82. Condition at end of fiscal year.-The existing project is about 98 percent complete. An outer harbor has been provided by con- structing breakwaters and pierheads completed in 1915, except the extension of the west breakwater to shore, which was com- pleted 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 1936. 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 turning basin opposite the National Tube Co. dock were deepened to project depth in 1937 and 1938 and the turning basin widened in 1944. RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2201 The work to be done to complete the project consists of deepen- ing the turning basin in the bend of Black River immediately up- stream from the Baltimore & Ohio Railroad coal dock. The protection works are generally in poor condition. At vari- ous locations on the lake face of the west breakwater, stones have shifted, leaving holes in the wall, and in many sections of the east breakwater the stones above water have deteriorated and shifted. The controlling depth was 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 harbor channel to the municipal pier, and 17 feet in the turning basin opposite the Na- tional Tube Co. dock, all at low-water datum. The total cost of the existing project was $4,103,233.03, of which $2,708,294.94, including $165,000 Public Works funds, was for new work and $1,394,938.09, including $76,300 Public Works funds, for maintenance. The total expenditures were $4,103,137.- 87, including $241,300 Public Works funds. In addition $3,000 was expended from contributed funds for new work. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $4,262.50, plus an anticipated allot- ment of $217,000 during fiscal year 1951, a total of $221,262.50, will be applied as follows: Accounts payable: June 30, 1950 .............................. $95.16 New work: Dredging turning basin in the bend of Black River immediately upstream of the Baltimore and Ohio R.

Local cooperation.--The act of March 2, 1945, provides for the 1,300-foot extension of the 21-foot channel in Cuyahoga River, subject to the condition that responsible local agencies give assur- ances 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 work and for subsequent maintenance, when and as required; (b) bear the expense of all necessary bulkhead and utility construction and alteration; and (c) hold and save the United States free from claims for damages resulting from the work; provided further, that the improvement on either side of the channel extension may proceed when the terms of local cooperation for that side have been met. These conditions have not been complied with for the left side of the extension looking downstream. The right side of the extension was completed in 1942 as a Defense Plant Corpora- tion project. All other conditions have been complied with. Terminal facilities.-There are approximately 45 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, and sulfur. In general, the terminals operated by the railroads which include two of the iron-ore and a coal terminal, are open to shippers of the commodities handled. The city of Cleveland owns three ter- minals, two of which are leased to vessel lines for miscellaneous freight and passenger terminals. 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 considered adequate for the existing commerce. (See Lake Series No. 5, revised 1939, Corps of Engineers.) Operationsand results during fiscal year.-New work : Prepara- tion of detailed plans and specifications for replacement or pier reconstruction of the railroad bridges and deepening Cuyahoga and Old Rivers was continued by hired labor and contract at a net cost of -$4,822.18 after an adjustment of costs for this item for the fiscal year 1949. Construction of bridge No. 25 over Cuya- 2206 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 hoga River by contract was commenced and Government costs in connection therewith were $2,847.46. Maintenance: Government plant and hired labor removed 177,- 452 cubic yards of material for restoration of project depth in the outer harbor and entrance channel at a cost of $67,885.51 and made repairs to the east breakwater and east pier at a cost of $130,952.25. Maintenance of the Cuyahoga and Old Rivers and outer harbor was continued and 672,657 cubic yards of material removed by contract at a cost of $454,445.88. The total cost for the year was $651,308.92 of which -$1,974.72 was for new work and $653,283.64 for maintenance. The total expenditures were $737,659.99. Condition at end of fiscal year.-The existing project is about 26 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 har- bor 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 portion of the east basin a depth of 23 feet at low- water datum has generally been secured. Portions of the channel in Quyahoga River were widened each year from 1939 to 1942: Removal of 150 feet of easterly end of west breakwater and con- struction 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 east end of east break- water in 1917 in lieu of the east-end pierhead. Providing a 1,300- foot extension of the Cuyahoga River channel to the present proj- ect limit was authorized by the River and Harbor Act of March 2, 1945, and partially completed wth Defense Plant Corporation funds during 1942. The harbor structures require extensive re- pairs. Completing the remainder of the channel extension, widening portions of the Cuyahoga River, deepening Cuyahoga and Old Rivers to 23 feet, and replacement or pier reconstruction of seven railroad bridges 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 chan- nel through the east basin, 23 feet. Depths elsewhere in the east basin within the project area range from 10 to 30 feet. The con- trolling depth in the Cuyahoga and Old Rivers was 21 feet, and in the turning basin, 18 feet. The total cost of the existing project was $13,534,758.84, of which $6,478,928.12, including $616,767.03 Public Works funds, was for new work and $7,055,830.72, including $125,000.00 Public RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2207 Works funds, for maintenance. The total expenditures were $13,- 391,354.52, including $741,767.03 Public Works funds. In addi- tion $50,000 was expended from contributed funds for mainte- nance. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $3,715,439.27, plus accounts receiv- able of $3,741.40, together with an anticipated allotment of $826,- 927.71 during fiscal year 1951, a total of $4,546,108.38, will be applied as follows: Accounts payable, June 30, 1950 .......................... $147,145.72 New work: Plans and specifications for improving Cuyahoga River by replacement or pier reconstruction of railroad bridges by hired labor and contract, July 1950 to June 1951 ........................... $196,407.44 Completion of replacement of Wheeling & Lake Erie Railway Co. bridge (No. 25) under existing contract, July 1950 to February 1952 ....................... 1,727,199.51 Completion of replacement of New York Central R.

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 chan- nel of approach to their terminal at their own expense. The River and Harbor Act approved July 3, 1930, waived the condition re- 2210 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 quiring 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 sub- ject to the condition that local interests agree to hold and save the United States free from damages resulting from the improvement. This condition has not been complied with. 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, five fish docks, 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. 9, 1939, Corps of Engineers.) Operations and results during fiscal year.-Government plant and hired labor removed 311,256 cubic yards of material from the outer harbor, river channel, and turning basin for restora- tion of project depths at a cost of $93,783.74. Repairs to the inner 400 feet of the east pier, by contract, were completed at a cost of $53,638.27. The total cost for the year was $147,422.01 for main- tenance. The total expenditures were $158,090.93. Condition at end of fiscal year.---The existing project is about 99 percent completed. A length of 400 linear feet of the east pier has been reinforced and repaired with steel sheet piling and con- crete. 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 break- water 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. The work remaining to be done to complete the project is the deepening to 8 feet of the westerly portion of the channel in Grand River at the upper end of the 21-foot channel. 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 and 18 feet in the turning basin. All depths are re- ferred to low-water datum. The total cost of the existing project was $3,840,342.34, of which $2,496,653.97, including $187,772.04 Public Works funds, was for new work and $1,343,688.37 for maintenance. The total expenditures were $3,841.850.42, including $187,772.04 Public Works funds. Proposed operations.-The accounts receivable at the end of the fiscal year amounting to $1,508.08, plus an anticipated allot- ment of $97,000 during fiscal year 1951, a total of $98,508.08, will be applied as follows: RIVERS AND HARBORS--BUFFALO, N.

RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2218 Local cooperation.-Extensionof the Ashtabula River channel up-stream of the turning basin is subject to the provisions that local interests give assurances satisfactory to the Secretary of Army that they will deepen to a like depth and maintain the area between the channel and the bulkhead and hold and save the United States free from claims for damages. These conditions have not been complied with. Prior conditions have been fully com- plied with. Terminal facilities.-There are three iron ore and two coal ter- minals 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, a large shipyard and drydock, and a car-ferry termi- nal also. 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 com- merce. (See Lake Series No. 9, 1939. Corps of Engineers.). Operations and results during fiscal year.-New work: The preparation of plans and specifications by hired labor for extend- ing the river channel was continued at a cost for the year of $48.03. Maintenance: Government plant and hired labor removed 139,- 412 cubic yards of material for the restoration of project depth in the channels at a cost of $51,848.81, and made repairs to the west breakwater at a cost of $56.85. The total cost for the year was $51,953.69, of which $48.03 was for new work and $51,905.66 for maintenance. The total expendi- tures were $52,048.03. Condition at end of fiscal year.-The existing project is about 96 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 completed in 1935. The old inner east breakwater 1,200 feet long was com- pleted 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 approach channel to the New York Central Railroad Co.'s slip and the channel in Ash- tabula River to a point 2,000 feet up-stream from its mouth were deepened to project depths in 1940. 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 existing project consists of deepening 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 deep- ened to that depth, shale rock being above project depth over a portion of the area. 2214 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The controlling depth is 25 feet in 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 turning basin. The total cost of the existing project was $3,817,965.74, of which $2,856,873.45, including $536,648.38 Public Works funds, was for new work and $961,092.29 for maintenance. The total expendi- tures were $3,818,705.30 including $536,648.38 Public Works funds.

Local cooperation.-Fully complied with. Terminal facilities.--Local interests maintain the river channel to provide access to terminals in the river, comprising one coal terminal which is open to shippers of coal, one iron ore, one stone, and one steel-products terminal which are private. The city of Conneaut owns a terminal and a small boat lagoon on the outer harbor which are open to the public. The facilities are considered adequate for the existing commerce. (See Lake Series No. 9, 1939, Corps of Engineers.) Operations and results during fiscal year.-Government plant and hired labor removed 115,570 cubic yards of material for the restoration of project depth in the outer harbor at a cost of $40,- 612.17 and made repairs to the west breakwater at a cost of $30,- 019.43. The total cost of maintenance for the year was $70,631.60. The total expenditures were $68,855.63. Condition at end of fiscal year.-The existing project is about 71 percent complete. Under 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 shoreward 800 feet (completed 1911) and lakeward 900 feet (completed 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 was 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 has settled approxi-, mately 6 feet to an average elevation of 4 feet above low-water datum. The inner 900 feet was built up to its original elevation during 1941 to 1949. At several places along the remainder of the west breakwater and along the east breakwater the slope stone along the lakeside is disintegrating and pulling away and the deck RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT2 2217 stone is settling. Other harbor structures are generally in fair condition. The controlling depth in the channel through the outer harbor is 25 feet below low-water datum. The work remaining to be done to complete the project is to deepen a 320-foot wide strip on the westerly side of the deepened channel through the outer harbor to 25 feet in soft material and 26 feet in hard material, and to deepen the remainder of the outer harbor to 20 feet. The total cost of the existing project was $4,088,600.64, of which $3,270,446.92, including $1,010,500 Public Works funds, was for new work and $818,153.72 for maintenance. The total expendi- tures were $4,087,995.36, including $1,010,500 Public Works funds.

Lake Survey Chart No. 332.) Previous projects.-Adopted by River and Harbor Act of May 26, 1824, and modifications were subsequently made by approval of the report of a board of engineers in 1855 and in 1865; by the River and Harbor Act of March 2, 1867; by approval of the report of a board of engineers in 1870; and by River and Harbor Acts of August 5, 1886, and September 19,1890. For further details see page 1965 of Annual Report for 1915, and page 1600 of Annual Report for 1938. Existing project.-This provides for the following: (a) An entrance channel 25 feet deep in soft material and 26 feet deep in hard material, 500 feet wide lakeward of the entrance piers, and 300 feet wide between the piers and into the harbor. (b) A channel of the same depths and 600 feet wide from the entrance channel to a line 50 feet outside of the pierhead line at the ore terminal, suitably widened at the junction with the en- trance channel. (c) A harbor area 21 feet deep, approximately 117 acres, ex- tending westerly from the 600-foot channel for a distance of about 2,100 feet to a line perpendicular to the harbor line 200 feet west of the city dock, with its southerly side 50 feet from the harbor line. (d) An approach channel 23 feet deep and 300 feet wide from the 25-foot channel to and including a turning basin of the same depth 1,200 feet long by 1,000 feet wide at the westerly docks. (e) An additional harbor area 18 feet deep, of about 35 acres, extending westerly from the 21-foot area and northerly from the harbor line off the public dock to natural deep water in the bay. (f) For harbor entrance piers 360 to 450 feet apart, of the tim- ber-crib type, with concrete superstructure extending to the 14- foot contour in the lake, the north pier to have a length of about 3,248 feet and the south pier to have a length of about 2,215 feet, further extensions lakeward to be made when required to meet advance of said contour. (g) A timber-crib breakwater 1,200 feet long (original length, 2,530 feet) with stone superstructure, extending from the inner end of the south pier toward the mainland to maintain a closure at the eastern end of the harbor and for plant growth and emer- gency protection work on the peninsula. The project depths are referred to low-water datum for Lake Erie, elevation 570.5 feet above mean tide at New York. Ordinary fluctuations of water level are from 3.5 feet above to 0.5 foot below low-water datum, and extreme fluctuations, produced by wind and other causes, are from 5.9 feet above to 2.7 feet below that plane. The estimate of cost for new work, revised in 1950, is $1,974,- 000, exclusive of amounts expended on previous projects. The lat- est (1948) approved estimate for annual cost of maintenance is $73,000. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-BUFFALO, N.

Local cooperation.-Providing an approach channel 23 feet deep, including a turning basin, to the westerly docks is subject to the condition that local interests give assurances satisfactory to the Secretary of the Army that they will: Provide and maintain a coal dumper and slip so that full utilization can be made of the improvement; lower the waterworks intake line where necessary; and hold and save the United States free from all claims for dam- ages incidental to the work or maintenance thereof. These condi- tions have not been complied with. Prior conditions have been fully complied with. Terminal facilities.-The developed water front 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, limestone and coal, one for petroleum, one for coal, one for pulpwood, one for sand and stone, one grain elevator, and one municipal pier used as a pas- senger 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. Operations and results during fiscal year.-Government plant and hired labor removed 228,872 cubic yards of material for res- toration of project depths in the channels and basin area at a cost of $59,286.87, made repairs to Presque Isle protection stone at a cost of $321.23 and made repairs to the south pier at a cost of $902.67. The total cost of maintenance for the year was $60,- 510.77. The expenditures were $71,644.33. Condition at end of fiscal year.-The existing project is 41 per- cent complete. The breakwater and piers were completed in 1915. A 3,050-foot section of rubble-mound protection work on the pe- ninsula 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 2220 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 the 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. In ap- proximately 1,040 feet of the north pier the concrete has disinte- grated, broken, and dropped. In the outer 200-foot section of the south breakwater the slope stone on the channel side has pulled away and dropped. In approximately 100 feet of the south pier the concrete has disintegrated, broken, and dropped. The Presque Isle Peninsula protection works are generally in good condition except for a 300-foot section of steel sheet pile and stone protec- tion built in 1930. The work remaining to be done to complete the project consists of dredging an approach channel and turning basin to the westerly docks, deepening the remaining portion of the approach channel to the easterly docks, and the conditional extension of the piers. 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 cost of the existing project was $3,722,499.30, of which $768,075.02 was for new work and $2,954,424.28 for main- tenance. The total expenditures were $3,722,614.56. In addition there was a cost and expenditure of $154,500 from contributed funds for maintenance. Proposed operations.-The accounts receivable at the end of the fiscal year amounting to $115.26, plus an anticipated allotment of $72,000 during fiscal year 1951, a total of $72,115.26, will be ap- plied as follows: Maintenance: Dredging the channels and basin, by United States hopper dredge, July, August and September 1950 .............. $44,920.54 Sweeping the channels and removing obstructions, by Govern- ment plant, August 1950 and May 1951 ................ 5,000.00 Repairs to outer end of south pier, by Government plant, October and November 1950 .......................... 22,194.72 Total ............................................ 72,115.26 The sum of $200,000 can be profitably expended for the follow- ing schedule of work during the fiscal year 1952 for maintenance: Dredging the channels and basin, by United States hopper dredge, summer 1951 ............................................... $50,000 Sweeping the channels and removing obstructions, by Government plant, summer 1951 and spring 1952 ......................... 5,000 Repairs to 540 linear feet of the north pier, by contract, summer and fall 1951 ................................................... 145,000 Total ................................................. 200,000 RIVERS AND HARBORS-BUFFALO, N.

S. ARMY, 1950 Local cooperation.-Deepeningthe south portion of the harbor and the south entrance channel to 25 feet, and removal of the shoals in lake approach to a depth of 27 feet are subject to the con- dition that local interests afford satisfactory assurances that the improvement of the ore and limestone terminal at the southern end of the outer harbor and the inner channels leading thereto, to fully utilize the increased depth afforded, will be undertaken to an extent sufficient to justify the cost of the improvement by the Federal Government. These conditions have not been complied with. The River and Harbor Act of March 2, 1945, modified the above requirement to permit deepening and maintaining to 23 feet of the shallow, undredged strip along the breakwater and the triangular area in the southerly outer harbor until such time as local interests meet prescribed local cooperation for dredging to 25 feet. All other conditions have been complied with. Terminal facilities.-There are approximately 50 terminals for the handling of all types of cargoes. The most important cargoes handled are iron ore, coal, grain, limestone, sand and gravel, steel products, scrap, flour, petroleum products, automobiles and sulfur. In general, the terminals operated by the railroads and lake-trans- portation companies and most of the grain elevators are open to the public. The city of Buffalo owns two wharves, one of which is used as an automobile terminal. The American Shipbuilding Co. has a drydock and facilities for repairing lake vessels. There are also several privately owned marine service, mooring and supply docks for lake vessels and smaller boats. The facilities are considered adequate for the existing' commerce. (See Lake Series No. 1, revised 1939, Corps of Engineers.) Operations and results during fiscal year.-New work: Plans and specifications, by hired labor, and dredging and rock excava- tion, by contract, for deepening of portions of Buffalo River (sec- ond stage), were continued at a cost of $559,885.86. Plans and specifications by hired labor for deepening portions of Buffalo River and Buffalo River entrance channel were commenced at a cost of $277.67. Maintenance: Government plant and hired labor made repairs to the south breakwater at a cost of $11,217.65, removed obstruc- tions from the Buffalo River entrance channel, north entrance channel, and outer harbor at a cost of $11,970.10, and removed 95,202 cubic yards of material for restoration of project depths in the Buffalo River entrance channel and outer harbor at a cost of $36,568.96. Maintenance of the Buffalo River and Ship Canal by contract was continued and 127,389 cubic yards of material were removed for restoration of project depths at a cost of $112,110.43. The total cost for the year was $732,030.67, of which $560,163.- 53 was for new work and $171,867.14 for maintenance. The total expenditures were $725,632.62. Condition at end of fiscal year.-The existing project is about 23 percent complete. The Stony Point breakwater was completed in 1899, a 1,000-foot extension was completed in 1914; 1,200 feet of the shore end was sold to the Lackawanna Steel Co. in 1918, and RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2227 another 1,000-foot extension was completed in 1935. The south breakwater was completed in 1903, and a 300-foot extension was completed in 1935. The north breakwater was completed in 1901, the old breakwater in 1893, and the south pier in 1869. The 23-foot project area in the outer harbor and the north-end entrance channel has been deepened to project depth except for strips 50 feet wide along the harbor line and 180 feet wide between the Superior Grain Corp.'s and the Merchants Refrigerating Co.'s piers. Buffalo River entrance channel has been deepened to 21 feet. 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 dropped and the riprap protection along the lakeside of the north- erly 1,200 feet of the old breakwater has settled. The controlling depth in the northerly part of the outer harbor is 23 feet and in the north and south entrance channels is 21 feet. Controlling depth in the Buffalo River channel is 20 feet, and in the southerly portion of the outer harbor it is 21 feet, at low-water datum. The work remaining to be done to complete the project consists of the removal to 27 feet of three small shoals on the direct ap- proach to the south entrance, the deepening of the north entrance channel to 25 feet in earth and 26 feet in rock, completion of deep- ening the Buffalo River entrance and Buffalo River and Ship Canal to 22 feet in earth and 23 feet in rock, and deepening of the 25-foot project area in the southerly part of the outer harbor and the remainder of the 23-foot outer harbor area all to project depths. The total cost of the existing project was $7,294,515.13, of which $3,687,157.35, including $655,500 Public Works funds, was for new work and $3,607,357.78 for maintenance. The total ex- penditures were $7,199,675.42. In addition there was a cost and expenditure of $390,000 from contributed funds for maintenance. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $198,923.88, plus accounts receivable of $15,325.42, together with an anticipated allotment of $1,123,000 during fiscal year 1951, a total of $1,337,249.30, will be applied as follows: Accounts payable, June 30, 1950 ........................... $110,165.13 New work: Completion of deepening portions of Buffalo River (second stage) to project depth, by contract, July 1950 ..................... $1,028.94 Deepen portions of Buffalo River and Buffalo River entrance channels to 22 feet in earth and 23 feet in rock, by contract, September 1950 to August 1951 .................. 934,782.04 935,810.98 Maintenance: Dredging Buffalo River and Ship Canal under existing contract, July 1950 ............. 60,000.00 Dredging Buffalo River entrance channel and outer harbor, by United States hopper dredge, July 1950 and June 1951 ........ 66,531.67 2228 REPORT OF CHIEF OF ENGINEERS, U.

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, Buf- falo, N. Y., to and including Tonawanda Harbor, N. Y. It com- prises the improvements formerly designated by three titles, viz. RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2229 Lake Erie entrance to Black Rock Harbor and Erie Basin, N. Y., Black Rock Harbor and Channel, N. Y., and Tonawanda Harbor and Niagara River, N. Y. (See U. S. Lake Survey Chart No. 312.) Previous projects.-Lake Erie section, none. The original proj- ect for Black Rock Harbor and Channel was adopted by the River and Harbor Act of March 2, 1829. The original project for Tona- wanda 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 Buf- falo north entrance channel to the foot of Maryland Street, Buf- alo, 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 deep- water pool at the upstream end of Rattlesnake Island, a distance of 3.4 miles; thence through natural deep water to the downstream end of the deep-water pool at the 'Tonawanda waterworks intake crib, a distance of about 4.7 miles, widened to 500 feet opposite the Wickwire Spencer Steel Co.'s plant by the removal 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 16 feet deep, 6,800 feet long, and generally 400 feet wide in Tonawanda Inner Harbor; 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 a bridge over the canal at Ferry Street, Buf- falo; 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. 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 31/2 feet below that plane. River fluctuations gradually decrease to about 70 percent of fluc- tuations above the lock when they reach North Tonowanda. 2230 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The estimate of cost for new work, revised in 1950, is $11,- 024,000, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $300,000, including $200,000 for operating and care. Description of Black Rock lock Location: Foot of Bridge St., Buffalo, N. Y.

RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2281 Local cooperation.-Fully complied with. Terminal facilities.-There are no freight terminals along the channel above the Black Rock lock. Transfer of freight takes place over the towpath to commercial plants on the east side. 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 six terminals for petroleum products, two for iron ore, stone, and pig iron, two for coal, one for automobiles, 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 Engineers 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. 11, revised 1939, Corps of Engi- neers.) Operations and results during fiscal year.-New work: Hired labor costs on completed contract for removal of rock shoals in Black Rock Canal amounted to $105.75 for the year. Maintenance: Government plant and hired labor removed 130,- 492 cubic yards of material for restoration of project depth in Black Rock Channel and Tonawanda Harbor at a cost of $91,195.- 59, swept and removed obstructions from the channels at a cost of $23,823.95, repaired Bird Island pier at a cost of $16,700.27, repaired the towpath wall at a cost of $1,203.87, and completed plans and specifications for dredging a channel in Niagara River below the locks, by contract, at a cost of $1,070.90. Operating and care: The lock was in continuous operation 245 days and in operation during the day only for 98 days. The lock was closed March 13 to April 3, 1950, inclusive, for underwater cleaning and repair. The Ferry Street Bridge was in continuous operation 306 days and in operation during the day only for 59 days. The signal station at the foot of West Genesee Street, Buf- falo, N. Y., was in continuous operation 252 days and was closed from December 25, 1949, to April 17, 1950. The cost for the year was $225,119.90. Contract plans and specifications for repairs to approximately 100 linear feet of guide pier, downstream end, were completed by hired labor at a cost of $1,872.53. In addition, a study to consider replacement or modernization of Black Rock lock and appurtenant structures was continued at a cost of $6,528.16. The total cost for the year was $367,620.92, of which $105.75 was for new work, $133,994.58 for maintenance and $233,520.59 for operating and care. The total expenditures were $357,463.65. Condition at end of fiscal year.-The existing project is about 92 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 2232 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 section in 1915; Niagara River section from lock to deep-water 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 enlarge- ment 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 200-foot northerly extension and construction of concrete platform in the angle. The bridge at Ferry Street was completed in 1914 and the lock-operating houses in 1924. The work remaining to be done to complete the project consists of the improvement and extension of the guide pier, as authorized by the River and Harbor Act of August 30, 1935, and widening the Lake Erie entrance to the canal. 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, required 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 channel face of the lock walls is badly deteriorated. 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. In a 100-foot section of the guide pier the concrete superstructure has cracked and settled. 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 total cost of the existing project was $13,709,106.43, of which $10,066,019.35, including $1,764,921.94 Emergency Relief funds, was for new work, $1,535,920.84 for maintenance and $2,- 107,166.24 for operating and care.

Recommended modifications of project.-Modifications of the existing project to provide for: a detached breakwater 850 feet long at the harbor entrance, and the removal of shoals to a depth of 25 feet below low water datum in the approach to the entrance all at an estimated cost of $1,811,000 for construction and $5,000 annually for maintenance in addition to that now required, have been recommended in House Document No. 487, Eighty-first Con- gress, second session. Local cooperation.-The act of June 30, 1948, provides for con- struction of the east outer harbor provided local interests give assurances satisfactory to the Secretary of the Army that they will provide without cost to the United States all necessary lands, easements, and rights-of-way necessary for construction of the 2246 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 project and subsequent maintenance, as and when required; hold and save the United States free from damage due to the con- struction and subsequent maintenance of the project; construct a wharf about 1,300 feet long, including the necessary extension of the water intake line, in accordance with plans approved by the Chief of Engineers, and construct handling and storage facilities of such design and capacity as to insure expeditious handling and adequate storage 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 reason- able and equal terms to all, the wood pulp requirements of paper mills in the vicinity. Assurances of local cooperation were fur- nished and submitted for approval. The assurances were returned without action because they were not in strict accordance with the requirements. Negotiations are in progress to obtain the revised assurances. All prior conditions have been complied with. 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, and one for fish are pri- vate. 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.Government plant and hired labor removed 15,860 cubic yards of material for resto- ration of project depth in the outer harbor at a cost of $9,191.39, and made repairs to the west arrowhead breakwater at a cost of $46,720.04. The total cost for the year was $55,911.43 for main- tenance. The total expenditures were $55,224.03. Condition at end of fiscal year. The, existing project is about 30 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 com- pleted in 1931 and the east arrowhead breakwater in 1932. The old lighthouse pier, a part of the west inner breakwater and 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 channel 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. A 250-foot-wide channel in the westerly outer harbor, 22 feet deep was completed in 1948. 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 100-foot portion of the concrete section has disintegrated and broken, and the core stone in the west arrow- head 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 RIVERS AND HARBORS-BUFFALO, N. Y., DISTRICT 2247 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 and construction of the east outer harbor. The total cost of the existing project was $4,920,997.65, of which $4,260,354.32 was for new work and $660,643.33 for main- tenance. The total expenditures were $4,921,117.28.

OWASCO INLET AND OUTLET, MONTVILLE AND DRY CREEKS, STATE DITCH, AND CRANE BROOK, N. Y. Location.-Owasco Inlet rises near Freeville, N. Y., in Tomp- kins County, N. Y., and flows northward 20 miles to Owasco Lake in Cayuga County, N. Y. The lake is 11 miles in length and dis- charges into Owasco Outlet, which flows northward 16 miles and empties into Seneca River. Montville and Dry Creeks are tribu- taries of the inlet, at and near the village of Moravia, N. Y., re- spectively, State Ditch being a tributary of the outlet. Montville Creek is also called Mill Creek locally. Crane Brook drains an area immediately west of the Owasco Basin and flows in a general northerly direction to the Seneca River. (See U. S. Geological Sur- vey quadrangle sheets, "New York-Auburn, Moravia, and Weedsport.") Existing project.-The project provides for the improvement of the channels of Owasco Inlet, Montville (Mill) Creek, and Dry Creek, replacement of two existing bridges spanning Dry Creek-- one a highway bridge to be done by local interests-and construc- tion of a dike along the north side of that stream; the improvement of State Ditch and the channel of Owasco Outlet; and the im- provement of Crane Brook, including the excavation of pilot 2270 REPORT OF CHIEF OF ENGINEERS, U.

(Contains latest published map.) 2288 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Local cooperation.-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 responsible 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 result- ing from the improvements. Conditions of local cooperation have not been complied with. Local interests state that a bond issue will be required to raise the $255,000 and they are unable to guarantee that amount until fiscal year 1951 or 1952. 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 $2,526,435 since 1916. Private interests have spent $682,000 for dredging and other harbor work, making the total expenditure for harbor improvements by local interests, $3,208,435, exclusive of the Federal project. Terminal facilities.-There are numerous small wharves and landings, practically all for yachts. Facilities are adequate for existing commerce. Operations and results during fiscal year.-Operationsconsisted of partially completing maintenance survey of the harbor by hired labor. The costs were $7,003.23 for maintenance. The expendi- tures were $6,432.36. Condition at end of fiscal year.-The existing project is about 76 percent complete. The units of the project authorized by the Public Works Administration were completed in 1936 at a cost of $1,593,793.66, half of which was contributed by local interests.

Local cooperation.-The River and Harbor Act of July 3, 1930, provides that before any work is undertaken on the turning basin, RIVERS AND HARBORS-LOS ANGELES, CALIF., DISTRICT 2291 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 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. The modification of the project in 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 reim- burse 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 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 24,785 linear feet of wharves, exclusive of Government-owned wharves of which 13,115 feet are municipally owned, and 10,670 linear feet by private interests. In addition, there are two wharves at Coro- nado and one Government-owned wharf at North Island. Facili- ties are considered adequate for existing commerce. Operationsand results during fiscal year.-Operationsconsisted of initiating maintenance dredging survey by hired labor. The costs were $702.58 for maintenance. The expenditures were $619.43. Condition at end of fiscal year.-The existing project is about 91 percent complete.

Location.-Located 17 miles south of the Oregon State line and midway between San Francisco Bay and the mouth of the Colum- bia River. (See U. S. Coast and Geodetic Survey Chart No. 5895.) Existing project.--This provides for a rubble mound breakwater approximately 5,700 feet in length, bearing approximately S-270 E. extending from Battery Point to Round Rock, a rubble mound sand barrier from Whaler Island to the easterly shore, an inner breakwater extending northwesterly from Whaler Island, so as to form a protected inner harbor, for maintaining, by dredging, a basin 1,800 feet long and 1,400 feet wide to a depth of 20 feet at mean lower low water, except in rock, for the removal of pinnacle rocks in the inner harbor ,and for maintenance dredging in the vicinity of the seaward end of the sand barrier. The range of tide between mean lower low water and mean higher high water is 6.9 feet; the extreme range of tide is about 12.3 feet. The estimate of cost for new work, revised in 1950, is $7,150,000 exclusive of $217,116 contributed by local interests. The latest (1950) approved estimate for annual cost of main- tenance, including $5,000 for dredging outside the harbor basin, but exclusive of the cost of maintenance of the inner harbor, is $82,500. The existing :project was authorized by the following river and harbor acts: Acts Work authorized Documents July 18, 1918 Bteakwater -------------------------------- H.

Terminal facilities.--There are three piers in the harbor, two of which are designated for public use. One public pier is in con- siderable need of repair and is not in use at the present time. There are two boat fueling stations. These facilities are con- sidered inadequate. Private concerns are constructing additional facilities. Operation and results during fiscal year.-As new work per- formed by continuing contract, 63,206 tons of stone were placed to complete 184 feet in the construction of the 1,700-foot extension of the main breakwater to Round Rock. The cost was $800,530.97. As maintenance work by contract 7,989 tons of stone were placed for repairs to the completed portion of the main breakwater. Periodic and annual condition surveys were made by hired labor. RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DISTBICT 2341 The costs of these items of maintenance work were $104,401.13 and $4,750.13 respectively, or a total of $109,151.26. The total costs were $909,682.23, and the expenditures were $836,572.92, all from regular funds. Condition at end of fiscal year.-The existing project is about 73 percent complete. The work remaining to be done includes the completion of the 1,700-foot extension of the main breakwater to Round Rock and removal of a pinnacle rock at the entrance to the inner harbor. The controlling depth of the shoreward por- tion of the project harbor is 7 feet, deepening to 15 feet in the outer half. In the inner harbor within a rectangular area about 800 feet wide and 900 feet long the depths range from 12 to 19 feet except near the boundaries of the area where the depths range from 10 to 12 feet.

NOYO RIVER AND HARBOR, CALIF. Location.--Noyo Harbor is a cove on the California coast about 135 miles northwest of San Francisco. Noyo River rises in the Coast Range Mountains, flows westerly, and empties into Noyo Harbor. (See U. S. Coast: and Geodetic Survey Chart No. 5703.) Previous projects.-Adopted by the River and Harbor Act of September 22, 1922. For further details see page 1680, Annual Report for .1929, and page 1772, Annual Report for 1930. Existing project.-This provides for a rubble-mound break- water extending northwesterly about 1,100 feet from the south headland of Noyo Harbor, and for an entrance channel into Noyo River 10 feet deep and 100 feet wide and a channel in the river 10 feet deep and 150 feet wide extending 1.15 miles above the mouth, to be obtained by dredging and jetty construction. All depths refer to mean lower low water. The tidal range between mean lower low water and mean higher high water is 5.8 feet. The extreme range is about 11.5 feet. The latest (1950) approved estimate of cost for new work is $1,995,000 excluding $7,180 of contributed funds. The latest RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DISTRICT 2845 (1950) approved estimate for annual cost of maintenance is $45,500.

Doc. 586, 80th Cong., 2d sess. (Contains latest published map.) IF 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. This requirement has been fully complied with for new work. The act of March 2, 1945, re- quires that local interests provide the necessary rights-of-way and easements for the construction and maintenance of the break- water, 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 ar- rangements for the loading and unloading of vessels in Noyo Har- bor. These requirements 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 devel- opment of the port facilities, which shall be open to all on equal terms, and provided such public body (a) furnishes, without cost to the United States, all lands, easements, and rights-of-way nec- essary for construction of the improvement; (b) agrees to hold and save the United States free from damages resulting from con- struction and maintenance of the project; (c) 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; (d) 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 con- struction thereon of impounding levees and to furnish royalty-free material for the construction of such levees, all when and as re- quired; and (e) agrees to contribute to the United States funds :equal to the Federal cost of constructing such levees as and when required. These requirements have not been complied with. Terminal facilities.-There are no facilities in the harbor prop- er. In the river above the harbor there are eight privately owned wharves and piers of which four have boat fueling stations there- on, 5 boat building and repair plants, one boat-fueling and icing terminal, and a number of mooring facilities. These facilities are considered adequate except the mooring and berthing facilities for fishing boats are inadequate. Improvement of the project as authorized will provide additional protected area for required facilities. Operations and results during fiscal year.---As maintenance work, periodic condition surveys were made at a cost of $2,690.93. The expenditures were -$3,372.81, from regular funds. 939127-51-vol. 2--58 2346 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Condition at end of fiscal year.-The project is about 15 per- cent complete. The work remaining to be done is the construction of the breakwater in Noyo Harbor and the extension of the chan- nel one-half mile upstream. In July 1949 the controlling depth at the entrance channel was 11 feet; between the jetties 6.5 feet, except for a small shoal 4 feet deep on the north side of the chan- nel; thence 9 feet to the head of the project with considerable shoaling to a depth of 1.6 feet along the northerly channel line and two small shoals +2 feet and -- 4 respectively along the southerly channel line.

Terminal facilities.-There are four dry docks, one vessel out- fitting wharf, seven wharves used in connection with oil-distribut- ing plants, and four wharves for general cargoes and other mis- cellaneous purposes. There are also numerous small yacht-moor- ing facilities along the river. These facilities are considered adequate for existing commerce. Operationsand results during fiscal year.-As new work dredg- ing, 1,569,078 cubic yards of material were removed from the proj- ect channel by contract at a cost of $863,034.17, with final costs outstanding. Advanced maintenance dredging was performed by contract removing 25,584 cubic yards of material remaining be- tween the new and old channel at Jack's Bend, at a cost of $16,- 997.61; periodic condition surveys were made by hired labor at a cost of $778.82, a total maintenance cost of $17,776.43. The total costs were $880,810.60, and the expenditures were $871,642.74. Condition at end of fiscal year.-The existing project is about RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DISTRICT 2355 89 percent complete. The remaining work consists of the comple- tion of a contract for dredging a small area at Jack's Bend and construction of dikes and revetments if required. In March 1950 the controlling depth was 15 feet from the mouth of the river to Asylum Slough, thence 10 feet to the upstream limit of the project. To the end of the fiscal year the costs for the existing project were $980,919.95 for new work and $35,462.52 for maintenance, a total of $1,016,382.47. The expenditures, all from regular funds were $1,007,956.46.

Terminal facilities.-There are 3 wharves along the southern shore of San Pablo Bay, 11 wharves and 2 ferry terminals along the southern shore of Carquinez Strait, and 5 wharves and 1 ferry terminal on the northern shore of this strait; in Mare Island Strait there are 6 commercial wharves and 3 ferry terminals, in addition to the navy-yard facilities. The facilities are adequate. ('See Port Series No. 12, Revised 1939 Corps of Engineers.) Operations and results during fiscal year.-The U. S. hopper dredges Mackenzie and Davison worked intermittently in Mare Island Strait and removed 1,902,919 cubic yards of material and the U. S. hopper dredge Mackenzie worked in Pinole Shoal from July 1 to July 16 1949 and removed 381,110 cubic yards of mate- rial, all at a total cost of $201,635.25. Floating debris was re- moved from project waterways by hired labor at a cost of $6,- 711.82. The total costs for the above maintenance work were $208,347.07 and the expenditures were $214,989.50, all from regular funds. Condition at end of fiscal year.-The project is about 97 per- cent complete. The work remaining to be done is the dredging of the two approved areas adjacent to Vallejo and South Vallejo. RIVERS AND HARBORS-SAN FRANCISCO, CALIF., DISTRICT 2357 In April 1950 the controlling depth throughout Pinole Shoal chan- nel was 35 feet. In Mare Island Strait it was 28 feet except at the upstream end of the turning basin where it was 28.5 feet as of February 1950. The costs of the existing project to the end of the fiscal year were $282,669.05 for new work and $2,837,541.84 for mainte- nance, a total of $3,120,210.89. The expenditures, all from regular funds, were $3,120,317.45. Proposed operations.-The unexpended balance on June 30, 1950, amounting to $6,674.68, together with accounts receivable of $106.56, and an anticipated allotment of $153,700, a total of $160,481.24, will be applied during the fiscal year ending June 30, 1951, to maintenance by redredging the channel and turning basin in Mare Island Strait intermittently throughout the fiscal year by United States hopper dredge. The additional sum of $250,000 can be profitably expended dur- ing the fiscal year 1952 for maintenance dredging of the channel and turning basin in Mare Island Strait and the channel across Pinole Shoal in San Pablo Bay.

Local cooperation.-The act of June 20, 1938, requires that local interests furnish necessary rights-of-way and spoil-disposal areas for initial work and subsequent maintenance and that no portion of the channel widening north of Point Potrero authorized by that act be undertaken until assurances are received that industries will avail themselves of the improved navigation facilities. These latter assurances have not been received. All other requirements have been fully complied with. Terminal facilities.-In the inner harbor there are four modern deepwater terminals, one oil wharf, three large privately owned wharves, one ferry terminal, one shipbuilding yard, and several small wharves used for miscellaneous purposes. In the outer har- bor there are three oil wharves, one deep-water general cargo wharf, one car-ferry terminal, one outo-ferry terminal, and about 10 wharves dealing in marine products. Local interests are plan- ning new facilities to accommodate expanding commerce. (See Port Series No. 12, Revised 1939, Corps of Engineers.) Operations and results during fiscal year.-As maintenance, floating debris was removed from the inner and outer harbor by Government plant and hired labor, at a cost of $6,711.82; periodic and annual condition surveys were made by hired labor at a cost of $8,394.08. The total maintenance costs were $15,105.90 and the expenditures $14,992.70, all from regular funds. Conditions at end of fiscal year.-The existing project is about 94 percent complete. The work remaining to be done is the widen- ing of the channel north of Point Potrero.

(Modifies Act of Jan. 21, 1927). Local cooperation.-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. Doc. 466, 77th Cong., 1st sess.). The first of the above requirements has been fulfilled. The others have not been fulfilled. In compliance with the act of April 28, 1928 (Public Res. 28, 70th Cong.), local interests have replaced the bridges at Park Street and High Street and are operating and maintaining them. They are legally unable to replace a combined railroad and highway bridge at Fruitvale Avenue because of a decision rendered by the Federal court that a municipality cannot contribute funds toward the betterment of a private corporation. The Southern Pacific Railroad Company operates trains over this bridge. The recommendation of the District Engineer to construct a separate railroad bridge has been approved by the Chief of Engineers and construction was initiated in June 1949. Terminal facilities.-There are 88 wharves, exclusive of those owned by the United States, 8 ferry terminals, and 1 large vege- table oil terminal in the harbor. These facilities are considered adequate for existing commerce. (See Port Series No. 12. Revised 1939, Corps of Engineers.) 939127-51-vol. 2----59 2362 REPORT OF CHIEF OF ENGINEERS, U. S.

REDWOOD CITY HARBOR, CALIF. Location.-Redwood Creek is a tributary of San Francisco Bay, about 20 miles south of the city of San Francisco. The works in- cluded under the project include, also, 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 from deep water in the bay to the junction of Redwood Creek and Westpoint Slough, with a flared entrance from the bay and an enlargement at a bend 1,800 feet long and 350 feet wide; a turning basin 2,200 feet long, from 400 to 900 feet wide and 30 feet deep; a channel 30 feet deep, 400 feet wide and about 1,300 feet long to a turning basin 30 feet deep, from 400 to 900 feet wide and 1,700 feet long at the junction of Redwood Creek and Boundary Slough; and a channel 150 feet wide and 5 feet deep from the turning basin to the old municipal wharf at the mouth of Steinberger Slough, about three-fourths of a mile below Redwood City. All depths refer to mean lower low water. The tidal range between mean lower low water and mean higher high water is 6.9 2364 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 separate sections under improvement, across San Bruno Shoal and in Redwood Creek, are each 4-1/3 miles long. The head of the improvement is two-thirds of a mile below the head of navigation at the Bayshore Highway crossing at Redwood City. The latest (1950) approved estimate of cost for new work is $1,416,000, exclusive of $119,572 contributed by local interests and of the amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $85,630.

Local cooperation.-TheRiver and Harbor Act of March 2, 1945, required that local interests furnish, free of cost to the United States, necessary easements for the construction and maintenance of the sand trap, and hold and save the United States free from 2370 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 claims for damages resulting from the improvements; and pro- vided, further that local interests bear the excess cost of placing dredged materials in disposal areas of their selection. These re- quirements have been complied with for the work performed to date. All prior requirements have been fulfilled. Terminal facilities.-Within the protected harbor the existing commercial facilities consist of two publicly owned wharves with a total of about 2,600 feet of berthing space, three boat-fueling sta- tions, two net-tanning plants, two machine shops and other facili- ties for servicing fishing boats, exclusive of facilities owned by the United States. Outside the protected harbor there are 1 boat-build- ing and repair plant, 35 anchored floating fish-receiving hoppers connected by pipe lines to sardine plants ashore, 2 submarine pipe lines between tanker moorings and shore plants for handling petroleum products and other facilities for servicing fishing boats. The facilities are considered adequate for existing commerce, although a state of congestion generally exists within the pro- tected harbor due to a lack of sufficient protected anchor mooring space. Operations and results during fiscal year.-As maintenance dredging, 9,759 cubic yards of material were removed from areas adjacent to Municipal Wharf No. 1 by contract at a cost of $15,- 253.17, a periodic condition survey was made by hired labor at a cost of $686.34. Under the provisions of section 11 of the River and Harbor Act of March 3, 1925, new work advanced funds in the amount of $45,520 expended for dredging the authorized project were returned to the city of Monterey. The total costs were $15,939.51. The expenditures were $63,476.22, all from regular funds. Condition at end of fiscal year.-The existing project is about 95 percent complete. The breakwater was completed in 1934. The work remaining to be done is the completion of dredging to project limits, of the authorized harbor depths adjacent to Muncipal Wharf No. 1 and the construction of the sand trap. In the com- pleted portion of the harbor the controlling depth was 8 feet as of May 1950.

Location.-The Russian River rises in Mendocino County and flows southeasterly for a distance of 90 miles, thence turns west for its last 20 miles to the Pacific Ocean at Jenner, Calif. (For the general location see U. S. Geological Survey map for the State of California.) Existing project.-The authorized project provides for the construction of the initial stage of the plan of improvement con- sisting of Coyote Valley Reservoir at mile 1 on the East Fork of the Russian River, and channel stabilization works on the lower 97 miles of the Russian River and on the lower reaches of several tributaries. The dam is an earth-fill type, with a total length of 4,600 feet, a crest at elevation 785, mean sea level datum, and a height above the stream bed of 150 feet. A paved overflow spill- way is to be located adjacent to the right abutment (looking down- stream), having a fixed crest at elevation 768 and a crest length of 410 feet. Gated outlet works, located through the dam, will provide capacity to empty the flood-control storage in about 4 days. The dam will create a reservoir having a capacity at spill- way crest of 122,000 acre-feet, of which 48,000 acre-feet are reserved for flood control and the remainder for water conserva- tion and siltation. The dam will control run-off from 105 square miles of drainage area. The latest (1950) estimated cost to the United States is $12,834,000. The estimated annual cost of main- tenance of Coyote Valley Reservoir is $18,900. The project was authorized by the Flood Control Act approved May 17, 1950 (H. Doc. 585, 81st Cong., 2d sess.). The latest published map is contained in the project document. 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; (a) Furnish free of cost to the United States all lands, easements, and rights-of-way necessary 2376 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 for the construction of the channel stabilization works; (b) make all necessary road and bridge revisions and utility alterations and relocations required for the channel stabilization works; (c) ad- just all claims concerning water arising from the construction and operation of the improvements; (d) hold and save the United States free from damages due to the construction works; (e) maintain the channel stabilization works, after completion, in accordance with regulations prescribed by the Secretary of the Army; (f) prevent any encroachment on the stream channel which would interfere with the proper functioning of the im- provements or lessen their beneficial effects; and, (g) enter into an agreement among themselves as to the method of operation of the reservoir for conservation subject to flood control priority. Operations and results during fiscal year.-None,. No funds have been appropriated. Condition at end of fiscal year.-No construction has been ac- complished. Proposed operations.-No work is contemplated during fiscal year 1951. The sum of $65,000 can be profitably expended during fiscal year 1952 for advance planning and preparation of plans and specifications by hired labor. 21. PAJARO RIVER, CALIF. Location.-The work is located on the Pajaro River at Watson- ville and on Carnadero Creek near Gilroy. (See U. S. Geological Survey quadrangles, Capitola, San Juan Bautista, and Morgan Hill, Calif.) Existing project.-This provides for the construction of levees on the right and left banks of the Pajaro River from near the mouth to high ground, about 6 miles upstream from Watsonville, with suitable bank protection; and the raising, enlargement, and lengthening of the existing levee on Carnadero Creek near Gilroy. The latest (1950) approved estimate of cost of new work, is $746,500, exclusive of estimated non-Federal costs of $336,000. The project was authorized by the Flood Control Act approved December 22, 1944, and is contained in House Document No. 505, Seventy-eighth Congress, second session. The latest published map is in that document. Local cooperation.- The act of December 22, 1944, requires that local interests provide without cost all lands, easements and rights- of-way necessary for the construction of the project; make at their expense all necessary changes in existing improvements, including utilities and highway and railway bridges, with the privilege of contributing $46,000 to the United States for special channel- construction work at the Watsonville highway bridge in lieu of bearing the expense of altering that structure; hold and save the United States free from damages resulting from construction of the work; and maintain and operate all works after completion in accordance with regulations prescribed by the Secretary of War. Local interests have fulfilled all requirements necessary for con- struction of the Pajaro River levees. Local interests in Santa Clara County, however, have not fulfilled the requirements for FLOOD CONTROL-SAN FRANCISCO, CALIF., DISTRICT 2377 construction of the Carnadero Creek levee. rThe State of California has officially adopted the project in chapter 1514, California Statutes of 1945. Operations and results during fiscal year.-As new Work, addi- tional costs were incurred in connection with the contract for the construction of levees in the amount of $13,057.46; emergency repairs and upkeep of the levees by hired labor prior to the ac- ceptance, of project by local interests, $7,878.05; completion of as constructed plans and preparation of manual of instructions and report, $3,574.04. The total costs were $24,509.55, and the ex- penditures were $43,259.47, all from regular funds. Condition at end of fiscal year.-With the exception noted be- low construction of the Pajaro River and Corralitos Creek levees was completed in January 1949. No work has been done on the improvement of Carnadero Creek because local interests have not met the requirements for the construction of the Carnadero Creek levee and have indicated that they are not in favor of this portion of the improvement. Therefore, no work is contemplated for this portion of the authorized project. The cost of the existing project to the end of the fiscal year was $712,580.12 for new work and the expenditures were $712,572.80. Proposed operations.-The unexpended balance as of June 30, 1950, amounting to $1,427.20, will be applied during the fiscal year 1951 as follows: Accounts payable June 30, 1950 ...................... ...... $7.32 Goveirnment cost in connection with closing out contract ........ 6.50 Funds to be revoked ................... ................... 1.,413.38 Total .......................................... ..... 1,427.20 No work is contemplated during fiscal year 1952.

SAN JOAQUIN RIVER, CALIF. Location.-San Joaquin River rises in east central California (in the Sierra Nevada) and flows southwesterly to the town of Mendota thence northerly, to its confluence with Sacramento River about 48 miles from San Francisco, Calif., to empty into Suisun Bay near Collinsville, Calif. Its total length is about 340 miles. Existing project.-This improvement provides for a channel 30 feet deep at mean lower low water and for channel-bottom width of 400 feet below Criminal Point 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 chan- nel) ; for a channel 26 feet deep and 100 feet wide, thence to Edison Street three-fourths mile; for a 9-foot depth, thence to the head of navigation at El Dorado Street, one-half mile; for a 9- foot depth in Fremont Channel and McLeod Lake, arms of Stock- ton Channel; and for a channel 9 feet deep and 100 feet wide in Mormon Channel from its mouth to Center Street, head of naviga- tion, 1.7 miles. It also provides for suitable passing basins and a turning basin at Stockton; for a triangular-shaped settling basin 30 feet deep and average side length of about 1,000 feet in the San Joaquin River just above its junction with the Stockton Deep Water Channel and a second settling basin 30 feet deep, 1,200 feet long, and 100 feet wide, adjoining the deep-water channel at the mouth of Calaveras River; for the reconstruction to grade and section of approximately 4,000 feet of levee along the north side of Venice Island Cut, and the setting back of levees where required for the channel improvements; for cutting off sharp bends and making cut-offs in the river; 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 over- hanging trees, and constructing brush-wing dams from the mouth of Stockton Channel to Hills Ferry, 86 miles, to facilitate light- draft navigation on this part of the river during higher stages of water. The River and Harbor-Flood Control Act of May 17, 1950 (Title 1, Rivers and Harbors, sec. 101 of Public Law 516, 81st Cong.) authorized modification of the navigation project for San Joaquin RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 2385 River, Calif., (H. Doc. 752, 80th Cong., 2d sess.), to provide for construction adjacent to Rough and Ready Island of a new turning basin 30 feet deep, 600 feet wide, and 1,350 feet long; widening the existing turning basin at Stockton by 200 feet; enlargement of Stockton Channel to afford a depth of 30 feet for a width of 150 feet between the existing turning basin and Weber Point; elimina- tion of dredging of Mormon Channel above Washington Street; filling of Mormon Channel and Mormon Slough between Washing- ton Street and Wilson Way to the extent that may be economically accomplished with dredge spoil from the improvement of Mormon Channel, upper Stockton Channel, and the existing turning basin; constructing a leveed channel, as necessary to meet the expanding needs of the port, 30 feet deep and 225 feet wide, around Rough and Ready Island including construction of a combination railroad and highway bridge; dredging a settling basin 17 feet deep, 600 feet wide, and 2,000 feet long, on San Joaquin River above the head of Burns Cut-off; and for levee changes and levee protective works below Stockton.

The latest (1950) approved estimate of cost to the United States of new work is $11,200,000. This amount does not include $1,307,500 previously contributed by local interests toward the cost of dredging and the $530,000 cash contribution required by the River and Harbor Act of May 17, 1950. The latest (1950) approved estimate of annual cost of maintenance is $175,000 an- nually. The existing project was authorized by the following river and harbor acts: 2386 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Acts Work authorized Documents Aug. 14, 1876 These acts provided for cutting off sharp bends and Mar. 3, 1881 making cut-offs in San Joaquin River below the July 5, 1884 mouth of Stockton Channel; dredging Mormon Aug. 11, 1888 Channel; snagging, removing obstructions, and July 13, 1892 constructing wing dams in San Joaquin River from Aug. 18, 1894 Stockton Channel to Hills Ferry; and the partial June 3, 1896 closing of side channels at Laird Slough and Para- dise Cut, without adopting any specific dimensions.

S Included in the Public Works Administration program, Sept. 6, 1933. Local cooperation.-All requirements for work accomplished to date under the authorization of the River and Harbor Act of August 26, 1937, have been fulfilled. In accordance with the above act, local interests are required to furnish, free of cost to the United States, suitable areas for the disposal of dredged material during the initial construction and future maintenance, and nec- essary rights-of-way, and shall assume the maintenance of levees. In accordance with the River and Harbor Act of May 17, 1950: Local interests are required to (a) except for the new turning basin, furnish free of cost to the United States all necessary lands, easements, rights-of-way, and suitable spoil-disposal areas for the new work and subsequent maintenance, when and as required; (b) agree to accept ownership of the combined rail and highway bridge upon completion of construction, together with mainte- nance, operation, and future replacement or alteration as may be required, provide and maintain any other bridges required over the waterway, and accomplish all necessary utility relocations and alterations and the maintenance thereof; (c) contribute progressively 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; (d) prior to enlargement 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 improvement under consideration; (e) agree to continue to maintain the levees along the deep water channel in- cluding those provided with bank protection by the Federal Gov- ernment and those bordering the improved channel around Rough RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 2887 and Ready Island; and (f) agree to hold and save the United States free from damages resulting from construction, mainte- nance, and operation of the proposed improvements. The neces- sary assurances have not been requested from local interests pending completion of detailed project plans. Terminal facilities.-The Port of Stockton owns and operates the Public Ocean Terminal consisting of 3,000 linear feet of wharves with 384,495 square feet of transit sheds, as well as 508 feet of open wharf. Eight oceangoing vessels can be accommo- dated at one time at the Public Ocean Terminal. The port also owns and operates 585,700 square feet of storage warehouses ad- jacent to the Public Ocean Terminal which includes a cotton ware- house and compress and a grain terminal with overhead conveyors to vessels having a capacity of 125 tons of bulk grain or 50 tons of sacked grain per hour. 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 Deep Water Channel on the north side, San Joaquin River on the east side, and Burns Cut-off on the south and west sides. Shallow-draft facilities on the upper channel include 7,780 linear feet of wharves of which 3,565 linear feet are privately owned, the remainder being owned by the Stockton Port District. Included along these wharves are 340,300 square feet of transit sheds and 127,600 square feet of storage warehouses. There is a privately owned cold-storage warehouse with an area of 83,474 square feet located on Mormon Channel. The port owns and operates the belt-line railroad, which con- nects with three transcontinental railroads and serves all facili- ties in the 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 im- mediate future. It is estimated that 800,000 to 900,000 tons of traffic per year can be handled with the present facilities, and with the extension of marginal wharves downstream from the Public Ocean Terminal, it is estimated that the yearly capacity of the port can be increased to 1,500,000 tons. Operations and results during the fiscal year.-New work: None. Maintenance: Dredging operations with the Government-owned hopper dredge Davison resulted in the removal of 37,400 cubic yards of material from the San Joaquin River opposite Jersey Island in December 1949, and 113,590 cubic yards of material from New York Slough in February 1950. Snagging in San Joaquin River in the vicinity of Mossdale, Calif., by hired labor and Government plant in December 1949 and January 1950 was accomplished. Operations also included preliminary surveys and preparation of plans by hired labor and driving of piles along the Stockton Deep Water Ship Channel for permanent bench marks by 2388 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1.'950 hired labor and Government plant. Total cost was $62,039.01 for maintenance, and total expenditures were $61,866.47. Condition at end of fiscal year.-The existing project is 35 percent complete. The work remaining to be done is the construc- tion authorized by the River and Harbor Act of May 17, 1950, for modification of the navigation project to provide for construc- tion adjacent to Rough and Ready Island of a new turning basin; widen existing turning basin at Stockton; enlargement of Stockton Channel between existing turning basin and Weber Point; con- struction of leveed channel, as necessary, around Rough and Ready Island including construction of a combination railroad and high- way bridge; dredging a settling basin on San Joaquin River above the head of Burns Cut-off; filling of a portion of Mormon Chan- nel and Mormon Slough; and for levee changes and levee protective works below Stockton. Dredging of the widened 30-foot channel, authorized by the River and Harbor Act of August 26, 1937, was completed in October 1940. The minor structures involved are in good condi- tion. 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 at El Dorado Street, one-half mile, 10 feet. A 10-foot depth is available in Mormon Channel, up to Main Street, 0.9 mile, thence 3 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 river, from its junction with Stockton Channel to the Mossdale bridges (16 miles), usually has a controlling depth of 4 feet from April to June, inclusive, and from the Mossdale bridges to Hills Ferry (70 miles) the usual controlling depth is 2 feet from April to June, inclusive. Navigation in the section above the San Joaquin Bridge (Southern Pacific Railroad crossing) is im- practicable in the low stages after June.

STOCKTON AND MORMON CHANNELS (DIVERTING CANAL), CALIF. Location. This is an artificial cut located about 2 miles north- east of Stockton. (See U. S. Geological Survey sheet, Stockton quadrangle.) Existing project.-This provides for diverting the waters of Mormon Slough before reaching Mormon and Stockton channels by means of a dam in the, slough 3 miles east of Stockton, and a canal 150 feet wide, with average cut of 7.9 feet, thence to the north branch of the Calaveras River, 4.63 miles; by the enlarge- ment of the cross section of this branch to 1,550 square feet, thence to its mouth at San Joaquin River, 5 miles; and by the construction of a levee along the west side of the canal and the south side of the north branch of the Calaveras River from the material excavated. The height of the levee is limited by necessary railway and highway crossings to about 3 feet above the contem- plated flood surface. The canal is empty during the greater part 2890 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 of the year, but at times of extreme flood there is a depth of about 12 feet, and at ordinary flood a depth of about 10 feet. The latest (1950) approved estimates of cost for new work and for annual maintenance are $280,395 and $8,000, respectively. The existing project was authorized by the River and Harbor Act of June 13, 1902 (H. Doc. 152, 55th Cong., 3d sess., and An- nual Report for 1899, p. 3188). The latest published map is in House Document 256, Sixty-third Congress, first session. Local cooperation.-Fully complied with. Terminal facilities.-See report on San Joaquin River, Calif. Operations and results during fiscal year.-Preliminary sur- veys, preparation of plans and specifications, inspections of sand removal, inspection and minor maintenance and rodent control works were accomplished by hired labor. Levee repairs, initiated in December 1948, were made along Calaveras River by contract and completed in October 1949, with 24,698 cubic yards of ma- terial placed during the fiscal year in embankment. Total cost for maintenance was $9,359.45 and total expenditures were $9,- 695.90. Condition at end of fiscal year.-All features of the existing project were completed in 1910. The structures involved are in good condition. Most of the silt formerly deposited in Stockton and Mormon channels is diverted therefrom by this canal, obviat- ing serious inconveniences to navigation and expensive annual dredging. The total cost was $385,312.69, of which $253,151.03 was for new work and $132,161.66 for maintenance. Total expenditures were $385,312.69.

Ordinarily flood fluctuation is 5.5 feet at the mouth and 12 feet at the upper end. Extreme flood fluctuation is 8 feet at the mouth and 17 feet at the upper end. The latest (1950) approved estimates of Federal cost for new work and for annual maintenance are $8,250 and $4,000, respec- tively. The existing project was adopted by the River and Harbor Act of July 5, 1884, Senate Executive Document 34, Forty-seventh Congress, first session (Annual Report for 1882, p. 2637). For latest published map see House Document No. 1160, Sixty-third Congress, second session. Local cooperation.-None required. Up to June 30, 1911, the State of California expended approximately $23,000 in clearing the river of snags and trees, for 3 miles above the Galt-New Hope Bridge, and in making several cut-offs. Two-thirds of the cost of this work was contributed by the local protection district. The result was to accelerate run-off and improve navigation conditions in the lower river. Other similar expenditures have been made by local interests, for which records are not available. Terminal facilities. The Western Pacific Railroad has ware- houses at Terminus, on Potato Slough; otherwise commodities are handled on small wharves or landings or on the banks at various points. The facilities are considered adequate for existing com- merce. Operations and results during fiscal year.-There were no operations and no costs were incurred. Expenditures were $89. Condition at end of fiscal year.-The existing project was com- pleted in 1885. Controlling depths are as shown in the table under existing project, with the following exceptions: Mouth of river to lower junction North and South Forks, 12 feet; Snodgrass Slough to upper junction North and South Forks via North Fork, 2 feet; and lower junction North and South Forks to upper junction of same at New Hope Landing via South Fork, 8 feet. The channel is reasonably free of obstructions to the head of navigation, except for a few that usually develop at low-water stages in the fall. The total cost was $76,037.01, of which $8,500 2392 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 was for new work and $67,537.01 for maintenance. Total expendi- tures were $76,037.01.

SACRAMENTO RIVER, CALIF. Location.-This river is formed by numerous streams draining the Trinity and Warner Mountains in northern California and empties into Suisun Bay at Collinsville. (See U. S. Geological Survey topographic map of the Sacramento Valley, Calif.) Previous projects.-Adopted by the River and Harbor Acts of March 3, 1875, August 2, 1892, December 21, 1889, July 13, 1892, and August 18, 1894. For further details see page 1985, Annual Report for 1915, and page 1708, Annual Report for 1938. Existing project.-This provides for construction of a ship channel 30 feet deep and 200 to 300 feet wide from deep water in Suisun Bay to Washington Lake, including such works as may be necessary to compensate for or to alleviate any detrimental salinity conditions resulting from the ship channel; a triangular basin of equal depth, 2,400 feet by 2,000 feet by 3,400 feet at Washington Lake; and a connecting canal 13 feet deep and 120 feet wide, with lock and drawbridge, thence to Sacramento River; thence 6 feet deep at low water to Colusa, 85 miles; thence 5 feet deep at low water to Chico Landing, 49 miles; and such depths as practicable, thence to Red Bluff, 53 miles. Below Sacra- mento the results are to be obtained by means of dredging and dry excavation of cuts of 30 feet for channel, 13 feet for canal, with related confining embankments, harbor excavation and struc- tures. The 10-foot channel project by the river route adopted in 1927 provides for a channel 10 feet deep at mean lower low water and from 150 to 200 feet wide from the mouth of the river to Sacramento. It has been completed and is still to be maintained for local navigation. Above Sacramento the results are to be obtained by removal of snags and concentration of the channel by temporary works, and stream-flow regulation by the Shasta Reservoir. All depths refer to mean lower low water.

The estimate of Federal cost for new work, revised in 1950, is $27,600,000 for the 30-foot deep water ship channel and 13-foot deep connecting canal, and $838,000 (approved in 1950) for shallow-draft river channels, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for an- nual cost of maintenance is $175,000 for the deep water channel and 13-foot deep connecting canal, and $250,000 for shallow-draft channels.

For map of the section below Sacramento, see H. Doc. 1123, 60th Cong., 2d sess. and S. Doc. 142, 79th Cong., 2d sess. Local cooperation.-No work shall be undertaken until respon- sible local agencies agree to furnish without cost to the United States all necessary lands, easements, rights-of-way, and spoil- disposal areas for the initial work and subsequent maintenance when and as required and to make all necessary utility changes, and until they give assurances satisfactory to the Secretary of 939127--51-vol. 2----61 2394 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 the Army that they will (a) construct, operate, and maintain at the Washington Lake Basin an adequate public terminal with necessary utilities and rail and highway connections open to all on equal terms, (b) hold and save the United States free from any damages which may arise from construction, operation, and maintenance of the improvement. These assurances have been furnished and accepted. The California Legislature on June 20, 1947, by chapter 1152, 1947 statutes, duly signed by the, Governor, appropriated $750,000 for the Sacramento-Yolo Port District for rights-of-way; contingent upon a showing satisfactory to the State director of finance (1) that approval of a bond issue (for $3,750,000) has been given by the voters of the port district, and (2) the making of a Federal appropriation for construction of the deep water channel to Sacramento, Calif. The first requirement was fulfilled by passage of the bond issue at an election of Novem- ber 4, 1947, and the second requirement was fulfilled by a Federal appropriation of $250,000 in July 1948 for initiation of construc- tion. A portion of the above bond issue is being used as needed in procurement of rights-of-way by the port authority; and the sum of $500,000 was advanced to the United States in June 1949 to accelerate construction, of which $100,000 of this advance has been returned to the port authority. Initial port facilities installation as planned by local inter- ests will consist of (a) one warehouse, 160 feet by 400 feet; (b) two transit sheds, 160 feet by 400 feet; (c) one grain elevator, 500,000-bushel capacity; (d) 1,500 linear feet of fireproof wharf; and (e) access road, railroad and utilities. A master plan cover- ing development of terminal facilities has been prepared for the future development of the port and will cover all future expansion after the initial development above described. The 500,000-bushel bulk-storage grain elevator with railway and highway connections was completed in 1950. A second portion of the railroad construction is underway. Recommended modifications of project.-In House Document No. 1883, Sixty-fourth Congress, second session, it was recom- mended that Chico Landing, 52.4 miles downstream from Red Bluff, be made the head of the improvement. This report is now under review. Terminal facilities.-At Sacramento there are 4,810 linear feet of wharves, of which 1,850 linear feet are owned by the city and 420 linear feet are open to general public use. There are 245,700 square feet of warehouse space, of which 103,700 square feet are owned by the city and 21,000 square feet are open to general public use. All the preceding is for shallow-draft navigation. All the main wharves at Sacramento have rail connection. Municipal belt railroad tracks serve the shedded wharves from the rear. A master plan has been prepared by the port authority for deep- draft terminal facilities at Washington Lake, across the river from Sacramento. A 500,000-bushel bulk-storage grain elevator, with railway and highway connections was completed in 1949-50. Plans have been drawn for 1,500-foot wharf, with two transit sheds and adjacent warehouses. RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 2395 On the west bank, opposite Sacramento, are four wharves of a total length of 350 feet, with 108,560 square feet of warehouse space, all privately owned and used. Between Sacramento and Chico Landing there are 47 warehouses and numerous small land- ings. 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, about 38 large warehouses, and many small warehouses and landings all owned and operated by private interests. The facilities below Sacramento, except at Rio Vista, are for shallow-draft navigation. They are considered ade- quate for existing commerce. Operations and results during fiscal year.-New work: Snag- ging and clearing along Sacramento River from Sacramento up- stream to Colusa, July to October 1949, and construction of five wing dams, mile 72.4 to 75.4, Sacramento River, September 1949 to February 1950, was accomplished by hired labor and Govern- ment plant. Advance planning for the 30-foot ship channel to Sacramento, including design and preparation of plans and spe- cifications for the Barge Lock and Bascule Bridge, was continued by hired labor throughout the fiscal year, and construction was initiated by placing 154,600 cubic yards of material, August to October 1949 by contract, and 1,074,211 cubic yards of material, July 1949 to February 1950, also by contract, in the road, rail- road, and levee embankments in the Harbor Area for the deep water channel. Total cost for new work was $671,280.06, of which $93,318.35 was for shallow draft and $577,961.71 for the 30-foot channel. Total expenditures were $633,840.54. Miscellaneous construction (nonproject) accomplished for the Sacramento-YoIo Port District at its expense in connection with acquisition of rights-of-way for road, railroad, and levee embank- ments and for engineering and design services cost $30,324.84 and expenditures therefor were $30,324.84. Maintenance: (a) Above Sacramento-Snagging, clearing of brush, and removal of obstructions was done by hired labor during May and June 1950 along Sacramento River from Butte City to Chico Landing, mile 169 to 193, and from Grimes to Wohlfrom's Bend, mile 125 to 155, at a cost of $62,346.60. (b) At and below Sacramento-Preliminary surveys and prepa- ration of plans and specifications for maintenance along the Sacramento River and tributaries was accomplished by hired labor throughout the fiscal year; acquisition and preparation of spoil area in November 1949 and preparation of spoil area, January through June 1950, all by hired labor and Government plant, was also accomplished incidental to maintenance dredging operations. Hired labor and rented clam-shell dredge were used to remove 67,788 cubic yards of material in Steamboat Slough during July and August 1949. A contract dredge removed 294,890 cubic yards of material from the river at Sacramento in November 1949. Cost of maintenance at and below Sacramento was $143,187.48. Total cost of maintenance for both sections was $205,534.08. Total expenditures were $203,191.76. 2896 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Total cost of all work during the fiscal year was as follows: Funds New work Maintenance Total United States funds.................--------------------------------- $671, 280. 06 $205, 534.08 $876, 814. 14 Contributed funds (nonproject).........-------------------------- 30, 324. 84 -------------- 30, 324. 84 Total of all funds.....--------------------------------701, 604.90 205, 534. 08 907, 138.98 The total expenditures were $867,357.14, of which $837,032.30 was from United States funds, and $30,324.84 from contributed nonproject funds. Condition at end of fiscal year.-The 10-foot channel below Sacramento was completed in 1931. The work remaining to be done to complete the shallow-draft portion of the project is the provision of a 6-foot depth between Sacramento and Colusa (85 miles) and a 5-foot depth thence to Chico Landing (49 miles), subject results to be obtained by removal of snags, construction of wing dams, and concentration of the channel by temporary works, and stream-flow regulation of 5,000 second-feet by opera- tion of the Shasta Reservoir; this work is 68 percent complete. Construction of the 30-foot deep water ship channel, under the modification authorized by the River and Harbor Act approved July 24, 1946, was initiated in July 1949 and is about 4 percent complete. Construction of road, railroad, and levee embankments in the harbor area was completed by contracts in October 1949 and February 1950. Project plans and preparation of contract plans and specifications, including the Bascule Bridge and the Barge Lock, were continued throughout the year. A contract was awarded in June 1950 for the initial dredging and levee con- struction feature, at the lower end of Sacramento Deep Water Ship Channel, mile 13.9 to 18.3; work will start in July 1950. The entire project as modified is about 6 percent complete. The controlling low-water season depths were as follows: From the mouth of the river to the mouth of Cache Slough, 20 feet; thence to Sacramento, 10 feet; thence to Colusa, 4 feet; thence to Butte City, 3.2 feet; and thence to Sidds Landing, 2.8 feet. There is no regular navigation above Sidds Landing, 178 miles above the mouth of the river.

Location.-This river rises in the Sierra Nevada, and empties into the Sacramento River about 21 miles above the city of Sacra- mento. (See U. S. Geological Survey sheet Topographic Map of the Sacramento Valley, Calif.) Previous projects. Adopted by River and Harbor Act of July 27, 1916, without previously published report. For further details see page 1985, Annual Report for 1915, and page 1711, Annual Report for 1938. RIVERS AND HARBORS-SACRAMENTO, CALIF., DISTRICT 2399 Existing project.-This provides for improvement of the river from its mouth to Marysville by providing for a channel of such depths as may be practicable at an average annual cost not in excess of $10,000, and that no local cooperation be required in addition to the contribution already made by local interests in accordance with the requirement of River and Harbor Act of July 27, 1916. The latest (1950) approved estimate for annual Federal cost of maintenance is $2,000. Ordinary flood fluctuation is 20 feet and extreme flood fluctua- tion is about 25 feet. The existing project was authorized by the River and Harbor Act approved January 21, 1927 (Rivers and Harbors Committee Doc. 1, 69th Cong., 1st sess.). Local cooperation.-Fully complied with. Terminal' facilities.-There are several small landings, all private- ly owned. All other traffic is handled on the bank. These facili- ties are considered adequate for existing commerce. Operations and results during fiscal year.-There were no operations, no expenditures, and no costs were incurred. Condition at end of fiscal year.-The existing project is one of maintenance and requires the removal of obstructions and con- struction of wingdams as needed. The controlling depth from the mouth at Verona up to Marysville is usually 3 feet from about February 15 to June 15. The channel and banks have been cleared of the worst obstructions and navigation thereby was facilitated. The total cost for maintenance and expenditures under the existing project were $5,742.91.

MIDDLE RIVER AND CONNECTING CHANNELS, CALIF. Location.-These waterways are part of a complicated network of tidal channels, some natural and some artificial, in the delta of the San Joaquin River. Middle River, one of the principal chan- nels, is a bychannel of the San Joaquin, leaving Old River, another bychannel above the city of Stockton and rejoining the main river 2400 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 about 15 miles below Stockton. Whiskey Slough enters the San Joaquin 6 miles upstream from Middle River and is connected by Empire Cut, an artificial waterway, with Latham Slough and Middle River. Turner Cut is an artificial cut-off at the mouth of Whiskey Slough. (See U. S. Geological Survey, California quad- rangles Bouldin, Woodward Island, Holt, Union Island, Stockton, and Lathrop.) Previous projects.-Adopted by the River and Harbor Act of July 3, 1930. For further details see page 1290 of Annual Report for 1934. Existing project.-This provides for a channel 9 feet deep and 100 feet wide in Middle River below Borden highway bridge; in Latham Slough between Middle River and Empire Cut; and in Empire Cut, Whiskey Slough, and Turner Cut between Middle River and San Joaquin River. The mean range of tide is about 3 feet during stages of extreme low water. The latest (1950) approved estimates of Federal cost for new work, exclusive of amounts expended on previous projects, and for annual maintenance are $6,500 and $2,000, respectively. The existing project was adopted by the River and Harbor Act of August 30, 1935 (Rivers and Harbors Committee Doc. 48, 72d Cong., 1st sess.). The latest published map is in the project docu- ment.

Location.-The streams comprising the Fresno County group are Big Dry Creek, Dog Creek, Redbank Creek, and Fancher Creek. All of them rise in the Sierra Nevada, near the foothills, from 17 to 31 miles northeasterly from Fresno, Calif., and follow nearly parallel courses in a southwesterly direction toward Clovis and Fresno. Portions of the channels of these creeks, after enter- ing the, valley floor, serve as part of large and complicated systems FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICTr 2409 of irrigation canals. The creeks eventually empty directly into the San Joaquin River, or indirectly through Murphy Slough, at various points northwesterly and southwesterly of Fresno, Calif. (See U. S. Geological Survey quadrangles of the area.) Existing project.--This provides for construction of a detention reservoir, with a storage capacity of 15,500 acre-feet, on Big Dry Creek about 10 miles northeast of Fresno; for diverting the floodwaters of Dog Creek to a point on Big Dry Creek above the reservoir; and for constructing a diversion canal from the reser- voir northwesterly to Little Dry Creek, a tributary of the San Joaquin River. The improvements will control floods on Big Dry and Dog Creeks considerably greater than any of recent occurrence and will provide complete protection to the cities of Fresno and Clovis and their suburban areas. The latest (1950) estimated Federal cost is $1,281,000 for con- struction. The existing project was adopted by the Flood Control Act of August 18, 1941. (See H. Doc. 845, 76th Cong., 3d sess., which 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 provide without cost to the United States all lands, easements, and rights-of-way necessary for the construction of the project, hold and save the United States free from claims for damages due to construction and maintenance of the project, bear the expense of bridge construction, and maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of the Army. Chapter 1514, Statutes of State of California, 1945, approved by the Governor of that State on July 19, 1945, provides for these assurances which have been furnished to and accepted by the Secretary of the Army. Satisfactory rights- of-way have been furnished by the State of California. Operations and results during fiscal year.-Construction was completed in February 1948. Condition at end of fiscal year.-Constructionwas completed in February 1948. Total cost and expenditures were $1,242,124.28, for new work. Proposed operations.-None. Project is completed.

ISABELLA RESERVOIR, KERN RIVER, CALIF. Location.-The area covered by this project comprises the upper watershed of Kern River and Poso and Caliente Creeks, the Kern and Buena Vista Lake areas and that portion of the San Joaquin Valley south of Tulare Lake Basin. Kern River is the most south- erly 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 southwest 72 miles past the city of Bak- ersfield 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 Basin by im- proved flood and irrigation channels. Under normal conditions of run-off the flow of Kern River below Bakersfield is gradually dis- sipated by irrigation diversions so that Kern River water reaches Tulare Lake Basin only during large floods. Poso Creek drains an area of 290 square miles lying west of Isabella and north of Kern River. Its flows are usually dissipated before reaching the valley trough. Caliente Creek drains an area of 470 square miles adjoin- ing the lower Kern Basin to the south. Its flows are dissipated in the valley floor south of Bakersfield. The valley area dependent for water supply on Kern River and Poso and Caliente Creeks, commonly called the service area, is approximately 1,560 square miles in extent. Existing project.-This provides for construction of Isabella Reservoir on Kern River, Calif., for flood control and other pur- poses, at an estimated Federal first cost (1950) of $19,050,000 and $71,000 annually for maintenance and operation. The existing project was adopted by the Flood Control Act of December 22, 2418 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 state they will meet these requirements. The State of California has officially adopted the project. Operationsand results during fiscal year.-New work: Prepara- tion of detailed plans for the project and contract plans and specifications for construction was continued. Educational facili- ties were furnished and land acquisition (including improvements, disposals, and damages) and operation of temporary housing facilities was continued. Excavation for the main dam outlet works by contract was started in July 1949 and completed in January 1950; 82,855 cubic yards of material were excavated, including tunnel and shaft excavation, and 19,362 pounds of steel supports were installed. Construction of a test fill for the main dam with a total of 12,120 cubic yards of embankment placed during the fiscal year by contract, initiated in April 1949, was completed in July 1949. Relocation of a portion of State Highway 142 by con- tinuing contract was initiated in September 1949, is about 10 per- cent complete, and will be completed about July 1952; relocation of the Fairview-Kernville County Road by continuing contract was started in February 1950, is about 10 percent complete, and will be completed about June 1951; and relocation of a portion of State Highway 57 by continuing contract was started in June 1950 and is to be completed about June 1952. Fabrication of slide gates and appurtenances for the main dam by supply contract was initiated in August 1949, is about 98 percent complete and will be com- plete about November 1950; Borel Canal slide gates by supply contract were started in March 1950, are about 41 percent com- plete, and fabrication will be completed about December 1950. Concreting of main dam outlet works and installation of gates by contract was started in June 1950 and will be complete about August 1951. A contract for construction of an administration building and garage was awarded in June 1950 and will be com- plete about December 1950.

KINGS RIVER AND TULARE LAKE, INCLUDING PINE FLAT RESERVOIR, CALIF. Location.-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 FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 2421 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 froni a completely dry condition to a body of water some 750 square miles in extent. There is no natural outlet from this lake as it is sepa- rated from the San Joaquin Basin by a low ridge, but lake waters have escaped 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. Existing project.-This provides for construction of the Pine Flat Reservoir with a gross storage capacity of 1,000,000 acre-feet and of supplemental channel improvement work, at an estimated total Federal first cost (1950) of $51,121,000, and $112,000 an- nually for maintenance and operation. 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 No. 367, Eighty-first Congress, first 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, Eightieth Con- gress, first 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 underway. The State of California has officially adopted the project. Operations and results during fiscal year.-Preparation of project plans and contract plans and specifications was continued. Land acquisition (including improvements, disposals, and dam- ages) and operation of the Government camp were continued and educational facilities were furnished. Relocation of Hughes Creek Road, Sunnyside Summit to Trimmer, Fresno County, initiated by contract in February 1948, was completed in September 1949; during the fiscal year work consisted of 38,807 cubic yards exca- vation and 4,885 cubic yards base course material. Construction of permanent Government administration area, initiated by con- tract in June 1949, was completed in November 1949. A bridge and measuring weir was constructed by contract July to Decem- ber 1949; work placed included 17,246 cubic yards excavation and 1,798 cubic yards concrete. Fabrication of sluice gates and appurtenances by continuing supply contract was initiated in August 1949 and is about 52 percent complete. Additional school 2422 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 facilities, to be constructed by contract at the Tivy Union School site, were initiated in June 1950 and are 10 percent complete. Construction of the main dam by continuing contract was initiated January 1950 ,and is about 6 percent complete. Work included 4,993 cubic yards excavation but consisted primarily of plant layout, construction of railroad, shops, water supply and distri- bution system and power lines, stripping of aggregate area, and grading and improvement of access roads to the project. Coffer- dam and first stage diversion was completed and the enclosure dewatered. Total cost of new work during the fiscal year was $3,286,738.76 and total expenditures were $2,214,120.48. Condition at end of fiscal year.-Project plans and preparation of contract plans and specifications and acquisition of land was continued. Construction work was started in April 1947; the proj- ect is about 16 percent completed. Excavation for the left abut- ment of the dam and construction of access road to the abutment area, construction and fencing of Hughes Creek-Pine Flat Detour Road, and relocation and installation of telephone lines were com- pleted in 1948. Work completed in 1949 includes: Provision of 24 portable two-bedroom houses, including paving and utilities, for project personnel; excavation for right abutment of the dam and access road to the area; construction and fencing of Hughes Creek Road, Sunnyside Summit to Trimmer; roads and utilities for the Government camp; permanent housing and facilities for operating personnel; and construction of a bridge and measuring weir. Construction of the main dam was initiated in January 1950 and will be completed about September 1954; construction of addi- tional school facilities at Tivy Union School site will be complete in September 1950; and fabrication of sluice gates and appurte- nances, started in August 1949, will be complete about May 1951. Work remaining to be done to complete the project includes: Spillway gates, utility modifications including relocation of exist- ing Forest Service facilities, reservoir clearing, and authorized channel improvements in the lower river area.

FOLSOM RESERVOIR, SACRAMENTO RIVER BASIN, CALIF. Location.-The proposed Folsom dam site is located on the American River about 21/2 miles above or northeasterly of the town of Folsom in Sacramento County, Calif., and about 1 mile below the confluence of the north and south forks of this stream. The proposed reservoir would extend from the dam site up the main river to this confluence and about 7 miles further 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 miles are above the proposed dam site. Existing project.-The authorization provided for the initial construction of a dam with gross storage of 355,000 acre-feet, and facilities for future power generation. The project, as modi- fied, provides for the reservoir to be constructed with a capacity of approximately 1,000,000 acre-feet and further provides for simultaneous construction of the power facilities by the U. S. Bureau of Reclamation, and subsequent maintenance and opera- tion of the completed project by that agency in conjunction with other units of the Central Valley Project. The existing project 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), as modified by the American River Basin Development Act (Public Law 356, October 14, 1949, 81st Cong. 1st sess.). The estimated (1950) Federal first cost is $50,792,000. Local cooperation.-None required, except payment for con- servation costs when used. The State of California has officially adopted the project.

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. 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 Basin. The southerly channel, 2428 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 Basin. Tule River, which drains an area of 420 square miles in 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. From this point the river con- tinues west about 40 miles across the alluvial fan to Tulare Lake Basin. Existing project.-This provides for construction of the Termi- nus and Success Reservoir projects, including supplemental spreading works at an estimated Federal first cost (1950) of $24,539,000, (including $13,395,000 for Terminus and $11,144,000 for Success), and $13,000 annually for Federal maintenance and operation of the reservoirs. The existing project was adopted by the Flood Control Act of December 22, 1944, (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. Local interests state they will meet these requirements. The State of California has officially adopted the project. Operations and results during fiscal year.- (a) Terminus Reser- voir on Kaweah River: The cost of new work during the year was $113,496.89 and the expenditures were $127,156.55 for work on project plan, including field explorations and surveys.

LOWER SAN JOAQUIN RIVER AND TRIBUTARIES, INCLUDING TUOLUMNE AND STANISLAUS RIVERS, CALIF. Location.-The San Joaquin River has its sources in the Sierra Nevada, and flows generally southwest through the mountains and 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 157 miles to Mossdale at the head of the San Joaquin delta, an extensive area of reclaimed tidal swamp lands through which the river flows with numerous side channels and sloughs to join the Sacramento River at the head of Suisun Bay near Pittsburg. 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. The lower San Joaquin River is under im- 2430 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 provement for navigation, the existing project providing for a 30-foot ship channel to Stockton and various minor improvements for the benefits of light-craft navigation in the delta channels. Existing project.-This provides for (a) construction of New Melones Reservoir on Stanislaus River, Calif., for flood control and other purposes, at an estimated Federal first cost (1950) of $43,400,000 and $30,000 annually for maintenance and operation; (b) an expenditure toward the first cost of the proposed Cherry Valley reservoir or other suitable reservoirs in the Tuolumne Basin, in amount justified by proportionate benefits to flood control, estimated at $12,000,000 (1950) for the equivalent of 340,000 acre- feet of storage at the Jacksonville Reservoir site; and (c) con- struction of channel improvement works and levee construction and reconstruction on San Joaquin River and tributary channels, at an estimated Federal first cost to the United States (1950) of $4,560,000. 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.) Recommended modifications of project.-In House Document No. 367, Eighty-first Congress, first session, it was recommended that power-generating facilities, not now included in the author- ized project, be constructed concurrently with and as part of New Melones Dam. For an initial installation of 41,000 kilowatts, the first cost is estimated (1948) at $4,727,000, and the annual cost for maintenance and operation at $224,000. 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. (b) In 'Tuolumne Basin: Local interests are to construct, maintain, and operate the dams and reservoir, allo- cate storage for flood control and agree to operate such storage in accordance with rules and regulations prescribed by the Sec- retary of the Army. (c) San Joaquin River: Local interests are to (1) furnish flowage rights to overflow certain lands along the main San Joaquin River and all lands, easements, and rights-of- way necessary for construction of levees; (2) hold and save the United States free from damages due to the construction works in the San Joaquin River and tributary channels, and their sub- sequent maintenance and operation; and (3) maintain all levees and channel improvements after completion in accordance with regulations prescribed by the Secretary of the Army. Chapter 1514, Statutes of State of California, 1945, approved by the Gov- ernor of that State on July 19, 1945, provides for the meeting of the latter requirements as to levee and channel improvement work. These assurances will be furnished when required. Operations and results during fiscal year.- (a) New Melones Reservoir (Stanislaus River) : The cost of new work during the year was $405.92 and the expenditures were $2,780.01 in the con- tinuation of preparation of the project plan. FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 2481 (b) Cherry Valley Reservoir, Tuolumne River Basin: A con- tract was awarded to local interests for modification of storage facilities at Don Pedro Reservoir, owned and operated jointly by the Modesto and Turlock Irrigation Districts, and Hetch Hetchy and Lake Eleanor Reservoirs, owned and operated by the city and county of San Francisco. Definite project plans, including devel- opment of and technical supporting data for rules and regulations covering flood control operations under phases I and II of the project, were continued. The cost of new work during the year was $101,299.27 and the expenditures were $105,960.22. (c) Construction of channel improvement works and levee construction on San Joaquin River and tributaries: The cost of new work during the year was $64,110.29 and the expenditures were $50,260.07 for continuation of preparation of the project plans, including field explorations and surveys, for construction of channel improvement works and levee construction along with bank protection and clearing. The total cost of new work for the project during the year was $165,815.48 and total expenditures were $159,000.30. Condition at end of fiscal year.- (a) New Melones: Preliminary project plans are in preparation, including studies of general flood control and irrigation benefits; planning is about 3 percent com- plete. Construction has not been started for this project. Total cost of new work was $63,155.84. Total expenditures were $70,- 094.32. (b) Cherry Valley Reservoir, Tuolumne River Basin: Project plans, including preparation of flood-control operation criteria, were continued. The contractors are operating their existing facili- ties in accordance with regulations prescribed by the Secretary of the Army to obtain immediately a degree of control over Tuo- lumne River floods. Review of cost estimate and schedule of con- struction submitted by the contractors was approved. Total cost of new work was $136,097.26 and total expenditures were $135,- 987.71. (c) Construction of channel improvement works and levee con- struction on San Joaquin River and tributaries: 'Preliminary proj- ect plans for construction of channel improvement works and levee construction along with bank protection and clearing are under- way; planning is about 19 percent completed. Construction has not been initiated. Total cost of new work was $85,841.93 and total expenditures were $80,779.36. 'The total cost of new work for the project was $285,095.03 and total expenditures were $286,861.39. Proposed operations.- (a) Stanislaus River-New Melones Res- ervoir: The balance unexpended on June 30, 1950, for Stanislaus River, amounting to $3,905.68, will be applied to payment of ac- counts payable, $61.52, and the balance of funds will be tempo- rarily reallotted to other authorized projects. The project may be considered inactive for the present owing to the fact that local interests are prosecuting planning and design work of storage and power facilities on this river that were not envisioned at the time of authorization. Accordingly, further studies are being held in 2482 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 abeyance pending decisions on the proposed plan of development as decided by local interests. (b) Tuolumne River (Cherry Valley Reservoir) : The balance unexpended on June 30, 1950, of $994,912.29 for Tuolumne River (Cherry Valley Reservoir), and an anticipated allotment of $500,- 000 during fiscal year 1951, a total of $1,494,912.29, will be ap- plied to payment of accounts payable. $109.55, and to cooperative planning with local interests who will build the Cherry Valley Dam and Reservoir, and as partial payment on a continuing con- tract basis of the Federal contribution to local interests (city of San Francisco and Turlock-Modesto Irrigation Districts) for such construction. (c) Lower San Joaquin River and tributaries: The balance unexpended on June 30, 1950, amounting to $9,220.64, and an an- ticipated allotment of $69,844.16, during fiscal year 1951, making a total of $79,064.80, will be applied to payment of accounts pay- able, $5,062.57, and to new work in continuing preparation of project plans, during fiscal year 1951. The additional sum of $4,000,000 can be profitably expended for Tuolumne River (Cherry Valley Reservoir) during fiscal year 1952 to continue cooperative planning with local interests, and for continuing payment of the Federal contribution to local in- terests for the construction of the dam and reservoir.

The authorization also provides for the construction of Black Butte Dam and Reservoir, an earthfill dam for flood control and water conservation, which is located on Stony Creek, a tributary entering the Sacramento River at mile 190, and westerly from Orland, Glenn County, California; and for the con- struction of the low-level Table Mountain (Iron Canyon) Dam and Reservoir, including power facilities, located on the Sacramento River a few miles above Red Bluff, in Tehama and Shasta Coun- ties, Calif. The approved estimated Federal first cost of the principal fea- tures is as follows: Levees, Sacramento River and tributaries, including Upper Butte Basin (revised in 1950), $28,000,000; Black Butte Dam and Reservoir (revised in 1950), $12,600,000; Table Mountain (Iron Canyon) (low level) Dam and Power Plant (revised in 1950), $62,850,000; a total first cost for the entire project of $103,450,000. The improvement was adopted by the Flood Control Act of De- cember 22, 1944 (H. Doc. 649, 78th Cong., 2d sess., which contains the latest published map), which authorized to be appropriated for the initiation of the project the sum of $15,000,000; and as further amended by the Flood Control Act of May 17, 1950 (H. Doc. 367, 81st Cong., 1st sess.), to include the necessary works of improve- ment for the protection of the Upper Butte Basin. Local cooperation.-See page 8 for requirements. With respect to conservation storage to be provided by the Table Mountain and Black Butte Reservoirs, 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 organiza- tions, is to be made to the United States by the State or other res- ponsible agency for this storage when used. Chapter 1514 of the Statutes of 1945, State of California, ap- proved July 19, 1945, provides for the furnishing of the required assurances of local cooperation as to levee and channel improve- ment work. These assurances have been furnished and accepted. All lands and rights-of-way required to date have been furn- ished by the State of California. Operations and results during fiscal year.- (a) Construction and enlargement of levees and local improvements on Sacramento River and major and minor tributaries: Construction of levees on the north and south banks of Deer Creek, Tehama County, initiated by contract in May 1949, was completed in November 1949. During the fiscal year 238 aci'es were cleared, 495,319 cubic 2484 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 yards of levee embankment placed, 29,079 tons of cobbles for bank paving placed, and 404 tons of crushed mineral aggregate surfacing placed. Advance planning, including detailed prepara- tion of plans and contract plans and specifications, was continued and is about 34 percent completed. A contract was awarded in June 1950 for levee construction and related work along Little Chico and Butte Creeks, downstream from Highway 99E; actual con- struction has not been initiated. The Federal co'st of new work during the fiscal year was $510,960.84 and the expenditures were $566,180.56. (b) Black Butte Reservoir: The cost of new work during the fiscal year was $89,270.24 for initiation of preliminary investiga- tions and planning studies for the construction of Black Butte Reservoir. The expenditures were $85,003.90. (c) Table Mountain Reservoir: Preparation of detailed plans and contract plans and specifications for construction of Table Mountain (Iron Canyon) Dam and Reservoir was continued. The cost of new work during the fiscal year was $17,920.70 and the expenditures were $22,183.09. 'Total cost of new work for the project during the fiscal year was $618,151.78 and total expenditures were $673,367.55. Condition at end of fiscal year.- (a) Construction and enlarge- ment of levees and local improvements on Sacramento River and major and minor tributaries: Advance planning, including pre- paration of detailed plans and contract plans and specifications, was continued. Construction of levees on north and south banks of Deer Creek, Tehama County, was completed in November 1949. A contract was awarded in June 1950 for levee construction and re- lated work along Little Chico and Butte Creeks, downstream from Highway 99E; actual construction is scheduled to start in July 1950. The project is about 3 percent complete. Work remaining to be done includes enlargement of existing levees on Sacramento River between Moulton Weir and Ord Bend; on Feather River between Marysville. and Gridley, and on Sutter, Tisdale, Yolo, Lower Yolo, and Sacramento Bypasses; construction of new levees on Sacramento River from Butte City to Chico Land- ing and in Lower Butte Basin.

REDMOND AND VICINITY, SEVIER RIVER, UTAH Location.-Sevier River drains an area of about 11,100 square miles of the Great Basin in southwestern Utah. It rises in the mountains of southern Utah, flows northerly about 240 miles, thence southwesterly 85 miles and empties into Sevier Lake which has no outlet. Redmond is on the west bank of the river 155 miles above its mouth. San Pitch River enters Sevier River from the east 12 miles below Redmond. The section of Sevier River Valley in this project extends from the crossing of U. S. Highway No. 89, near Salina, about 3 miles above Redmond, downstream to the head of Sevier Bridge Reservoir, a total distance of 25 miles. The drainage area above Redmond is 3,820 square miles. Upstream from the section under consideration the basin consists of rugged plateaus and mountains cut by narrow stream valleys. Between Salina and the San Pitch River, the stream flows through a moun- tain valley averaging about 4 miles wide. Sediments carried from the steeper upstream areas and deposited in the valley section have raised the stream bed about 10 feet during the past 40 years. The channel, which in 1900 could carry about 2,600 cubic feet per second, now has a bankful capacity of about 400 cubic feet per second and is bordered by extensive swamps. Existing project.-The plan provides for the improvement of Sevier River in the vicinity of Redmond, Utah, by construction of a leveed channel commencing near Salina and extending about 50,000 feet downstream, of a levee extending from the Westview Diversion Dam at its proposed relocated site to Redmond Lake Dam, and of two diversion dams, at an estimated cost (1950) to the United States of $929,000 for construction. The existing proj- FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 2437 ect was adopted by the Flood Control Act of December 22, 1944. (See H. Doc. 614, 78th Cong., 2d sess., which contains the latest published map.) Local cooperation.-Local interests are to contribute $48,000 additional to the first Federal cost, and furnish 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- way necessary for construction of the works; (b) hold and save the United States free from damages due to the construction works; (c) construct the three new highway bridges and the ir- rigation flume required, extend and improve the two irrigation canals, extend the outlets of the existing tile drainage system to the improved river channel, and construct the open drainage ditch at Redmond; and (d) maintain and operate all the works after completion in accordance with regulations prescribed by the Sec- retary of the Army. The above contribution has been made, and the required assurances furnished and accepted. Operations and results during fiscal year.-Construction of channel improvements, initiated by contract in July 1948, was completed in December 1949.

SPANISH FORK RIVER, UTAH Location.-Spanish Fork River rises in the Wasatch Moun- tains in the southeastern part of Utah County, Utah, and flows northwesterly to Utah Lake, a component of the Jordan River system draining into Great Salt Lake near Salt Lake City. The flood-control improvements are located in the lower 13 miles of the river near Spanish Fork, Utah. Existing project.-The plan of improvement provides for the control of floods by improving the river channel and constructing levees for a distance of about 6.7 miles from the mouth of the river at Utah Lake upstream to the county highway bridge west of the town of Spanish Fork, and improving about 2 miles of the channel at critical points through a reach of about 6.3 miles up- stream from the county highway bridge. Modification of two diversion dams, revision of bridge and road facilities, and pro- visions of necessary protective works at bridge abutments and piers within the limits of the improvements would be required. The project will provide a substantial flood protection for 2,250 acres of improved land in the basin. The existing project was authorized by the Flood Control Act approved July 24, 1946. (See H. Doc. 518, 79th Cong., 2d sess., which contains the latest map.) The approved estimated Federal first cost (revised in 1950) is $185,000 and estimated cost to local interests is $51,000. Local cooperation.-See page 8 for requirements. In addition, local interests are required to bear the expense of all necessary alterations of roads, bridges, utilities, and irrigation works. The FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 2439 necessary assurances have not been requested from local interests pending completion of detailed project plans.

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 improve- ments are located in and adjacent to Salt Lake City. Existing project.-The authorized plan of improvement pro- vides for the construction of flood-control works on Jordan River at Salt Lake City, Utah, consisting of a dike and control structures in the river and in the heading of the Surplus Canal at their junction, and by dredging and improving the channel of the river from the southern boundary of the city downstream for a distance of approximately 8.9 miles; enlarging and extending Surplus Canal, with a levee on the east bank, from its heading on Jordan River for a distance of about 7.2 miles; and by modifying existing railroad, highway, and utility facilities. The proposed improve- ment would provide complete protection to the area adjacent to Jordan River through Salt Lake City from anticipated floods on that stream. The existing project was authorized by the Flood Control Act approved July 24, 1946. (See H. Doc. 562, 79th Cong., 2d sess., which contains the latest map.) The approved estimated Federal first cost (revised in 1950) is $950,000 and estimated cost to local interests is $290,800. Local cooperation.-See page 8 for requirements. In addition, local interests are required to bear the expense of all necessary alterations and construction of highway facilities, irrigation works, and other utilities except railroad bridges and control structures at the junction of Jordan River and the Surplus Canal.

MAGNA, LITTLE VALLEY WASH, UTAH Location.-Little Valley Wash rises on the northeast slope of the Oquirrh Mountains in the western part of Salt Lake County and discharges upon the flat land in the northwestern section of the valley. Water from the stream eventually finds its way direct- ly into Great Salt Lake or is lost through evaporation and transpi- ration in the flat lands between Magna and the lake. Magna is located on the debris cone where Little Valley Wash debouches from the mountains. Existing project.-The plan of improvement consists of a chan- nel about 1.1 miles long extending from the mouth of the canyon northward to an existing debris basin formed by a circular levee. The upper 5,000 feet of the channel would be concrete-lined and a levee would be constructed on the east side of the channel ad- jacent to the town. Necessary modifications to bridges, utilities, and irrigation facilties would be made. The existing project was authorized by the Flood Control Act approved July 24, 1946. (See H. Doc. 562, 79th Cong., 2d sess., which contains the latest map.) The estimated Federal first cost (approved in 1950) is $575,000, and the cost to local interests $21,000. Local cooperation.-See page 8 for requirements. In addition, local interests are required to assume the responsibility for con- struction of culverts at highway and irrigation canal crossings. The necessary assurances have not been requested from local interests, pending completion of detailed project plans. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done. Proposed operations.-No funds are available and no operations are proposed for the fiscal years 1951 and 1952. FLOOD CONTROL-SACRAMENTO, CALIF., DISTRICT 2441 26. HUMBOLDT RIVER AND TRIBUTARIES, NEV. Location.-Humboldt River rises in the mountains of north- eastern Nevada near the town of Wells and for about two-thirds of its length flows generally westward to Winnemucca, thence southwestward for the remainder of its length to its end in the evaporation pans of Humboldt Lake and Carson Sink in western Nevada. The river basin of approximately 16,700 square miles is a high semiarid plateau crossed by numerous steep mountain ranges separated by broad, flat valleys. The length of the river valley is about 300 miles, however, the river is much longer due to its extensive meandering. The principal headwater tributaries are North Fork and Marys River from the North and South Fork from the south. There are no important tributaries along the lower two-thirds of the river below Palisade, Nev. Reese River, which joins Humboldt River near Battle Mountain, has a relatively large drainage area but contributes flow very infrequently; and Little Humboldt River, which formerly joined the main stream near Winnemucca, is no longer a surface tributary due to the formation of a sand barrier across the lower end of its valley. Elevations in the basin vary from about 4,000 feet in the Carson Sink to about 10,000 feet in the Independence Mountains at the headwaters of North Fork, and about 12,000 feet in the Ruby Mountains at the headwaters of South Fork. Below Palisade, the slope of Humboldt River averages about 2.5 feet per mile of actual channel length. Existing project.-The project provides for improvement of Humboldt River and tributaries, in Nevada, for flood control and other purposes, by construction of three storage reservoirs on headwaters tributaries, minor channel improvements at critical locations along Humboldt River above Rye Patch Reservoir, and a system of drainage canals, a pumping plant, and a dike to con- fine water to the lower portion of Humboldt Lake, for drainage improvement in Lovelock Valley. The storage reservoir dams are to be earth fill structures and are in the general vicinity of Elko, Nev., with storage reservoir capacities as follows: Hylton Reservoir on the South Fork of Humboldt River, 120,000 acre-feet; Devils Gate Reservoir on the North Fork of Humboldt River, 80,000 acre-feet; and Vista Reservoir on Marys River, 50,000 acre-feet. The estimated Federal cost, based on the June 1950 cost index, for the principal features of the project is as follows: Hylton Res- ervoir $3,524,000, Devils Gate Reservoir $2,686,000, and Vista Reservoir $3,564,000. The total first cost of this portion of the project is $9,774,000; however, local interests are to contribute $2,762,000 prior to construction, leaving a net Federal first cost of $7,012,000. The estimated Federal cost for the minor channel improvements and major drainage improvements is $191,000 and $1,118,000, respectively, giving a total approved Federal first cost of $8,321,000 for construction of the entire project and an annual cost of $75,100 for maintenance, operation, and major replace- ments for the reservoir projects. The improvements was adopted by the Flood Control Act of 939127--51-vol. 2---64 2442 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 May 17, 1950 (See H. Doc. 586. 81st Cong., 2d sess., which con- tains the latest published map). Local cooperation.-Local interests are to contribute $2,762,000 toward the first Federal cost of the dam and reservoirs prior to initiation of construction, and in addition furnish assurances sat- isfactory to the Secretary of the Army that they will: (a) Furn- ish without cost to the United States all lands, easements, and rights-of-way necessary for the channel and major drainage im- provements and make all utility revisions required; (b) construct all lateral drains and appurtenant facilities needed to supple- ment the major drainage improvements and to assure effective drainage in Lovelock Valley; (c) maintain and operate all chan- nel and drainage improvements and appurtenant works after com- pletion, in accordance with regulations prescribed by the Secre- tary, of the Army; (d) hold and save the United States free from damages due to the construction of channel and drainage im- provements and appurtenant works; and (e) enter into an agree- ment among themselves as to the method of operations of the reservoirs for conservation subject to flood control priority. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done. Proposed operations.--No funds are available and no opera- tions are proposed for fiscal years 1951 and 1952. 27.

Location.-The site of this project is on Columbia River, imme- diately downstream from the mouth of John Day River and about 217 miles above the mouth of Columbia River. Existing project.-The project will provide for a dam, power plant, navigation lock, and appurtenant facilities. The improve- ment will provide for navigation, flood control, and power genera- tion. A 75-mile slack-water pool will be provided from the John Day Dam to McNary Dam. The dam, which will raise the normal water surface about 94 feet to elevation 255 feet above mean sea level, will also provide for 2,000,000 acre-feet of surcharge storage space between elevation 255 and 292 for control of floods on Colum- bia River. The dam, about 4,100 feet long, will consist of a con- crete non-overflow section forming the Oregon abutment, a navi- gation lock, a gate controlled spillway section, a concrete non- overflow section, a powerhouse section, and a concrete nonover- flow section forming the Washington shore abutment. Suitable facilities for passage of migrating fish will be provided. The pow- RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2455 erhouse will have 13 generating units of 85,000 kilowatts each, making a total installed capacity of 1,105,000 kilowatts. The spillway dam will be 1,310 feet long and will be located in the south half of the channel. The overflow crest at elevation 223.5 feet above mean sea level will be surmounted by 22 gates designed to pass a design flood of 2,250,000 cubic feet per second and to be capable of creating a maximum controlled pool elevation of 292 feet above mean sea level for control of floods. Deck elevation will be 297 feet above mean sea level and a service road and track for two gantry cranes will be provided. The navigation lock will have clear plan dimensions of 86 feet by 675 feet and a single lift of about 94.5 feet maximum. The lock will operate at all flows less than 800,000 cubic feet per second. All structures will be founded on a massive flow of Columbia River basalt which forms the bed- rock at the site. 'The estimated cost of the project, revised to 1950 costs, is $433,000,000. The existing project was authorized by the Flood Control Act approved May 17, 1950, House Document 531, Eighty-first Cong- ress, second session. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done or ex- penditures made. Proposed operations.-No work is scheduled for the fiscal years 1951 or 1952. 2. COLUMBIA RIVER AND TRIBUTARIES ABOVE CELILO FALLS TO KENNEWICK, WASH. Location.-This project includes improvement of the 128-mile stretch between the head of Celilo Falls and Kennewick, Wash. For brief description of Columbia River see page 2496. (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; 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.; for removal of obstructions in the channel from the mouth of the Snake River to Kennewick, Wash.; and for an approach 6 feet deep from the channel in the Columbia River to the site of terminal developments at Kennewick. The section included in the project is 128 miles long. The lower end of the project is about 200 miles from the mouth of the river. The summer freshets occur from May to August and the ordinary freshets reach a stage of 21 feet on Umatilla gage. The highest flood (1894) reached a stage of 341/2 feet at Umatilla. Freshets 2456 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 due to rains sometimes occur in the early winter, but rarely exceed a 9-foot stage. Ice conditions, usually occurring in January or February, sometimes suspend navigation for 2 weeks or more. The McNary Dam authorized by River and Harbor Act ap- proved March 2, 1945, will, when completed, obviate the necessity of channel work between the lower end of Umatilla Rapids and the mouth of the Snake River. The latest (1950) approved estimate of cost for new work is $1,581,600 exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of mainte- nance is $120,000. The existing project was authorized by the following River and Harbor Acts: Acts Work authorized Documents 1 Apr. 8, 1935 Emergency Relief Appropriation Act; authorized the ( existing project as an emergency relief project. Rivers and Harbors Committee Aug. 30, 1935 Adopted existing project as a river and harbor project. ( Doc. 16, 73d Cong., 2d sess. Mar. 2, 1945 Arlington approach channel_ _ __....... ..... _ S.

Local cooperation.-TheRiver and Harbor Act approved March 2, 1945, provides that for each of the Arlington and Kennewick channels local interests give assurance that they will construct a suitable freight terminal, open to all on equal terms, and for the Kennewick channel that they furnish free of cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas necessary for the improvements and their subsequent maintenance, when and as required, and hold and save the United States free from claims for damages resulting from the improvements. Assur- ances of cooperation for work at Arlington were approved Decem- ber 29, 1947, but a suitable freight terminal has not yet been con- structed. Terminal facilities.-There is one public wharf on this stretch of the river located at Pasco, Wash. (mile 127.2 above Celilo), and owned by the port of Pasco. A bulk-grain elevator of 500,000- bushel capacity, with rail, truck, and water connections, is located adjacent to the wharf at Pasco; and a 300,000-bushel capacity grain elevator is located at Arlington, Oreg. Other facilities for handling bulk grain from truck to river craft, but without rail connections, are as follows: Two private warehouses at Port Kelly, Wash. (mile 110.6 above Celilo), with capacities of 40,000 and 44,000 bushels; a 340,000-bushel elevator at Umatilla (mile 88 above Celilo); and a 40,000-bushel elevator at Blalock (mile 32 above Celilo). There are privately owned storage facilities for handling petroleum products with capacities and locations as follows: At Pasco, Wash. (mile 127.2 above Celilo), 5,000,000 gallons with rail, truck, and water connections; at Attalia, Wash. (mile 117 above Celilo), 4,381,000 gallons with truck and water connections; and at Umatilla, Oreg. (mile 88 above Celilo), 14,- 455,825 gallons of which 8,155,825 gallons has rail connections RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2457 and 6,300,000 gallons with truck and water connections only. There is a railroad located on each bank of the river, but there is no physical connection between the railroad and the river except as noted. The existing facilities are not considered adequate for the present commerce, but additional facilities are being provided as rapidly as economic conditions permit. Operations and results during fiscal year.-Maintenance: Re- moval of sand, gravel and boulders from Four O'clock and Canoe Encampment Rapids by Government plant and hired labor result- ed in providing adequate depths for barge traffic over the entire project. The channel was in continuous use for the entire year except for the period from January 14, 1950, to February 18, 1950, when ice conditions prevented navigation. A total of 17,885 cubic yards of material was removed at a cost of $68,314.62. Hy- drographic surveys were made as required at a cost of $5,062.83. Total costs and expenditures for the fiscal year were $73,377.45, all for maintenance. Condition at end of fiscal year.-The existing project is approxi- mately 90 percent complete. The authorized 7-foot channel, 150 feet wide, has been completed to the foot of Umatilla Rapids where the controlling depth is 6 feet in a 75-foot channel and 5 feet in the 150-foot channel. The controlling depth between the foot of Umatilla Rapids and Wallula is 6 feet in a 100-foot channel through Umatilla Rapids. Between Wallula and the mouth of Snake River, the controlling depth is 5 feet for a 100-foot width through Homly Rapids. Between the mouth of Snake River and Kennewick, the controlling depth is 6 feet in a channel 200 feet wide. The channel is in continuous use over the entire project. Transportation by barge of petroleum products upstream and wheat downstream comprises most of the traffic. Construction ma- terials for use in McNary Dam are being barged from Portland to the damsite. The remaining work required to complete the proj- ect consists of channel rectification at Indian Rapids, Squally Hook Rapids, and Owyhee Rapids, which are below McNary Dam, and the excavation of the Kennewick Channel. Total costs and expenditures under the existing project, from Federal funds, have been $2,062,077.39; of which $1,331,584.37 (including $400,000 Emergency Relief funds) was for new work and $730,493.02 for maintenance.

THE DALLES DAM, COLUMBIA RIVER, WASH. AND OREG. Location.-The site of this project is on Columbia River at the head of the pool behind Bonneville Dam, approximately 192.5 miles above the mouth of the river and 90 miles east of Portland, Oreg. Existing project.-This project provides for a dam and power plant, navigation lock, and appurtenant facilities. The improve- ment will provide for navigation and hydroelectric power genera- tion. The dam will raise the normal water surface elevation about 87.5 feet at the site and create a reservoir extending upstream about 25 miles to the proposed John Day Dam. The dam will be about 8,400 feet long and will consist of a concrete nonoverflow dam and an earth and rock embankment on the Oregon shore, a powerhouse in the south part of the channel, a concrete nonover- flow section, a spillway dam, a concrete nonoverflow section adja- cent to the Washington shore, and a navigation lock at the north abutment. Suitable fish passing facilities, including three ladders, will be provided. The 1,478-foot powerhouse will have 14 generat- ing units with a capacity of 70,000 kilowatts each, making a total installation of 980,000 kilowatts. The spillway dam will be 1,848 feet long and will be located in the north channel. The overflow crest at elevation 119 feet above mean sea level will be surmounted with 30 gates which will provide capacity to pass a design flood of 2,290,000 cubic feet per second. The deck will be at elevation 185 feet above mean sea level and will provide a service road and track for two gantry cranes. The navigation lock will have clear plan dimensions of 86 feet by 675 feet and a single lift of about 87.5 feet maximum. The lock will include a 1,400-foot guard wall to protect boats and tows from currents toward the spillway. The structure will be founded on Columbia River basalt. The estimated cost of the project as revised in 1950 is $326,- 366,000. The existing project was authorized by the Flood Control Act approved May 17, 1950, House Document 531, Eighty-first Cong- ress, second session. RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2459 Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done or ex- penditures made. Proposed operations.-No work is scheduled for the fiscal year 1951. The sum of $250,000 is needed to be appropriated during the fiscal year 1952 for detailed planning of the project. 4. THE DALLES-CELILO CANAL, OREG. AND WASH. Location.-This improvement embraces about 12 miles of the Columbia River between The Dalles and Celilo, Oreg. (See U. S. Geological Survey map of Oregon.) Previous projects.-Adopted by the River and Harbor Act of August 18, 1894. For further details see page 1993 of Annual Report for 1915 and page 1842 of Annual Report for 1938. Existing project.-This provides for open-river improvement from the foot of Threemile Rapids to the foot of The Dalles (Five- mile) Rapids, and a continuous canal on the Oregon shore from the foot of The Dalles (Fivemile) Rapids to the head of Celilo Falls, the canal to have a depth of 8 feet, width of 65 feet at the bottom, and length of 81/2 miles, with four locks, as follows: Detailed information of locks Dimensions Lift Miles Great- Avail- from est able When lower Lock Foundation length depth com- Cost en- avail- Clear Low High on pleted trance able for width water water lower full sill width Feet Feet Feet Feet Feet 0 Big Eddy lock'-...

There are no dams in the canal. The lower end of the canal is about 4 miles and the lower end of the Threemile Rapids about 11/2 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 nor- mal 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 estimate of cost for new work, revised in 1908, was $4,- 845,000, exclusive of amount expended on previous projects. The estimate of annual cost of operation and care, made in 1948, is $172,000. 2460 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The existing project was adopted by the River and Harbor Act of March 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 ap- proved June 26, 1934. For latest published map see Annual Report for 1915, page 3380. Local cooperation.-Fully complied with. Terminal facilities.-None. Operationsand results during fiscal year.-The canal and locks were in continuous operation throughout the fiscal year except for the periods from 7:15 p.m., July 20, to 3:30 a.m., July 23, 1949, for repairs, and from January 15 to February 17, 1950, because of ice conditions in the locks and canal. The various items of maintenance (operation and care) and their costs were as follows: Operation of the locks and canal ............................ $91,848.66 Ordinary maintenance and repair .......... ................ 15,106.97 Improvement and reconstruction work was continued and com- pleted on the following features during the fiscal year: Fire protection pump and water line at Celilo Lock by hired labor .............................................. 4,346.81 Fire protection pump and water line at 5-Mile Lock by hired labor ......................... ............... 2,199.16 Electrify bridges 1, 3, 5, 6, and 9 by hired labor .......... 2,546.30 Continue power line from Celilo to 10-Mile Lock by hired labor ............................................... 497.72 Remove old water tower, Celilo Lock, by hired labor ...... 610.61 Replace guide pier No. 4, Celilo entrance, by hired labor .... 506.92 Replace fender logs, Celilo entrance and Celilo boat basin by hired labor .......................................... 496.39 Removal of 30,664 cubic yards of sand and silt from the locks and canal ......................................... 12,243.52 Total costs for fiscal year ......................... 130,403.06 Expenditures were $132,481.06. Condition at end of fiscal year.-The canal and locks were com- pleted in 1919. The originally constructed tandem locks were con- verted into a single-lift lock in 1941. The available dimensions of the canal and locks are inadequate for the increased width and drafts of vessels now using those facilities. Navigation interests continue to request enlargement and modernization of the existing facilities. Project dimensions are maintained thoughout the year. Total costs under the existing project have been $6,269,340.49, of which $4,669,092.33 was for new work, $5,445.17 for mainte- nance, and $1,594,802.99 for operation and care. Total expenditures have been $6,271,123.19. In addition, the sum of $525,267.16 was expended between May 5, 1915, and June 30, 1935, on operation and care of the work of improvement, under provisions of the permanent indefinite appropriations for such purposes. Proposed operations.-The funds unexpended June 30, 1950, plus accounts receivable amounting to $15,640,31, plus an antici- pated allotment of $151,000, a total of $166,640.31, will be applied as follows: RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2461 Accounts payable .......................................... $283.21 Operations ..................... ................... ......... 90,020.00 Ordinary maintenance and repair ........... ,................. 25,280.00 Channel work ........................................... 16,907.00 Improvement and reconstruction: Complete replacement of guide pier No. 4 by existing contract 14,150.10 Widening the lower entrance to Big Eddy Lock by contract October to December 1950 ............................. 20,000.00 The additional sum of $115,000 can be profitably expended during the fiscal year 1952 for operation and care, including opera- tion, ordinary maintenance and repair, and channel work.

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 2496. Existing project.-This project provides for a dam, power plant, and lock, for power and navigation. The spillway dam extends across the main river channel from the Washington shore to Brad- ford 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 2 units of 43,200 kilowatts each and 8 units of 54,000 kilowatts each, totaling 518,400 kilowatts. The ordinary and extreme fluctuations of the river at the lower 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 depth of 20 feet and over between Bonne- ville and Big Eddy, a distance of 47 miles.

The work remaining to be done to complete the project con- sists of the completion of miscellaneous items of work in the powerhouse and other project features. The total costs and expenditures of work done under emergency funds to the end of the fiscal year amounted to $32,440,700, all for new work. The total costs of the work done under regular funds to the end of the fiscal year amounted to $58,269,975.90 (includes undis- tributed costs amounting to $165,195.69), of which $50,091,079.05 was for new work and $8,178,896.85 for maintenance (bperation and care). The total expenditures were $58,257,589.12. The total costs, all funds, to the end of the fiscal year amounted to $90,545,480.21, of which $82,531,779.05 ($38,990,647.02 for power facilities and $43,541,132.03 for other features of work) was for new work and $8,013,701.16 for maintenance (operation and care), including $3,903,417.99 for operation and care of power facilities. Total expenditures were $90,698,289.12, of which $25, 996,743.38 was for power installation only, units 3-10, and $64,- 701,545.74 for installation of power, units 0-2, construction of all facilities other than power, operation, and maintenance. Power production and revenues.-Electricalpower energy gen- erated, excepting that portion required for the operation of the project, is delivered to the transmission lines of the Bonneville Power Administration for disposition in accordance with the terms of the Bonneville Act. During 1950 fiscal year a total of 3,689,309,000 kilowatt-hours was so delivered and 19,255,000 kilo- watt-hours used for operation of the project, a total of 3,708,564,- 000 generated. Receipts from power sales by the Bonneville Power Adminis- tration are deposited in the United States Treasury as required by law, but allocated to the project in accordance with memorandum- of-understanding with the Administration. Amounts so allocated are independent of the amount of power generated and delivered and are designed to cover (a) operation and maintenance expense applicable to power operations, (b) interest at the rate of 2.5 percent per annum on that portion of Government expenditures allocated to power, and (c) scheduled repayment of construction costs, including replacements, allocated to power, over a 50-year period. During the fiscal year 1950 the amount of $3,418,000 was so deposited, of which sum the amount of $1,914,969.82 was for operating and interest expenses applicable to power, and $1,503,- 030.18 for amortization of construction costs applicable to power. 2466 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 In addition, the Administration during the fiscal years 1948-50, inclusive, has deposited in the United States Treasury a total of $6,100,000 as advances or repayments against scheduled amortiza- tion requirements. These prepayments, together with the regularly scheduled payments, will result in the completion of the amortiza- tion well within the 50-year period originally contemplated. As of June 30, 1950, and including the $6,100,000 advance payments, the sum of $34,626,000 has been deposited in the United States Treasury to the credit of the project, of which $19,678,157.93 was for operating and interest expenses applicable to power operations, and $14,947,842.07 for amortization (including replacements) of construction costs applicable to power. Of a total of $90,698,289.12 expended to date on the project for construction, operation and maintenance and replacements, the amount of $62,402,725.48, or 68 percent, has been for direct and allocated portions of power features. Net remaining unpaid Government investment on June 30, 1950, allocated to power features amounted to $44,032,581.47, a reduc- tion in investment of $3,232,345.49 from the previous fiscal year.

Location.-On Columbia River, between the Interstate Bridge at Vancouver, Wash., 106.5 miles above the mouth and The Dalles, Oreg.-;mile 191, a distance of 84.5 miles. For description of Colum- bia River see page 2496. Existing project.-This provides for a channel 27 feet deep at low water and 300 feet wide between Vancouver, Wash., and The Dalles, Oreg., 85 miles; a channel 10 feet deep at low water and 300 feet wide at the upstream entrance to Oregon slough, Oregon; a suitable turning basin adjacent to the site of port development in the vicinity of Camas and Washougal, Wash.; a boat basin at Hood River, Oreg., 500 by 1,300 feet and 10 feet deep at normal Bonneville pool level, with a connecting channel of the same depth to deep water, and a protecting breakwater on the easterly side; a barge channel to the waterfront at Bingen, Wash., 10 feet deep at normal Bonneville pool level, 200 feet wide and approximately 1 mile long, and for an access channel 7 feet deep at normal Bon- neville pool level, 100 feet wide and approximately 1,000 feet long, RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2469 to a natural mooring basin for small boats near the east end of the channel; and for the construction of The Dalles Harbor, Oreg., to provide a breakwater and shear boom protected basin approxi- mately 400 by 800 feet in size with depth of 8 feet below a pool elevation of 72.5 feet mean sea level. The tidal range between mean lower low water and mean higher high water at Vancouver is about 21/2 feet and at Bonneville about 0.2 foot at low stages of the river. Extreme tidal ranges are about 3 feet and 0.4 foot respectively. Annual freshets average about 21 feet at Vancouver, while the highest known stage reached 33 feet above low water. The estimate of cost for new work, revised in 1950 is $6,104,000. The latest (1948) approved estimate for annual cost of mainte- nance is $260,000.

Local cooperation.-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 bulk- heads provided by them; and provides that no dredging will be performed by the United States within 50 feet of the proposed dock. 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. For The Dalles, the act of July 24, 1946, provides that local interests (a) furnish free of cost to the United States all lands, easements, and rights-of-way required for new work, and suitable spoil-disposal areas for new work, and for sub- sequent maintenance when and as required, (b) provide necessary bulkheads, and (c) agree to construct, maintain, and operate within the basin suitable moorages and a public landing with ade- quate supply facilities, open to all on equal terms. Assurances of 2470 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 local cooperation for The Dalles harbor were approved by the Secretary of the Army, October 5., 1948. Terminal facilities.-The only terminal facilities at present available or suitable for ocean vessels on the stretch of the river under the project are at The Dalles, Oreg. The port of Camas- Washougal has constructed a wharf 528 feet in length at Wash- ougal, Wash., which will be available for ocean vessels when an adequate entrance 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 of both ocean vessels and river boats. There are two one-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 terminal for han- dling petroleum products from ocean vessels and river boats. Storage tanks have rail and truck connections. A private elevator with a capacity of 40,000 bushels and a public elevator of 868,000 bushels capacity for handling bulk grain to ocean or river craft are also located at The Dalles. The public elevator has rail and truck connections. There is a privately owned rail connection about three-fourths miles below the muncipal wharf where certain types of cargo may be handled between railroad cars and river boats or barges, by means of a derrick of 22-ton capacity. The facilities are considered adequate for present commerce. Operations and results during fiscal year.-New work: Con- struction of the small boat-mooring basin at The Dalles. Oreg., ini- tiated on March 8, 1949, by contract, was completed on October 17, 1949. Removal of rock at mile 10 above Interstate Bridge was com- pleted by Government plant and hired labor on October 12, 1949. This rock removal at mile 10 completed the channel excavation to project dimensions between Vancouver, Wash., and Bonneville. Maintenance: Seasonal maintenance dredging at locations where shoaling had occurred was performed by the Government pipe-line dredge Luckiamute. A total of 134,880 cubic yards of material was removed at a cost of $45,124.74 to maintain available depths of 15 feet for barge traffic. Hydrographic surveys were made at a cost of $8,189.19. Total costs for the fiscal year were $132,322.34, of which $79,- 008.41 was for new work and $53,313.93 for maintenance. Expen- ditures were $133,470.28. Condition at end of fiscal year.-The existing project is approxi- mately 52 percent complete. Dredging of the main channel between Vancouver and Bonneville was completed October 12, 1949. This channel at the present time is used for barge transportation and log towing and is maintained to a depth of 15 feet which is ade- quate for the existing traffic. Depths of 20 feet or more are avail- able between Bonneville and The Dalles, Oreg. No construction work has been done on the 27-foot channel between Bonneville and The Dalles, the channel at the upper entrance to Oregon Slough, the Camas-Washougal turning basin, the Hood River boat RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2471 basin, the Bingen channels, or the improvement of the lower en- trance to Bonneville ship canal. Total costs have been $3,492,584.23, of which $3,074,513.32 was for new work and $418,070.91 for maintenance. Expenditures have been $3,492,584.23. Proposed operations.-An anticipated allotment of $56,332 will be applied as follows: Maintenance: Dredging to restore navigable depth of 15 feet for a width of 300 feet in the channel between Vancouver, Wash., and Bonneville, Oreg., by Government plant and hired labor, November and December 1950 ................. $51,625.00 Hydrographic surveys as required ...................... 4,707.00 Total ............................................ 56,332.00 No work is scheduled for fiscal year 1952.

Terminal facilities.-Between Portland and Willamette Falls the terminals are privately owned mill wharves and oil receiving sta- tions. Above the falls there are small wharves privately owned or natural landings. These facilities are considered adequate for the existing commerce. Operations and results durzng fiscal year.-Dredging by hired plant and Government plant and the removal of snags by Govern- ment plant maintained sufficient depths for the requirements of present navigation. The various items of maintenance and their costs during the fiscal year were as follows: Dredging by hired plant and Government plant, 810,142 cubic yards ........................... ..................... $352,295.37 Snagging in Willamette and Yamhill Rivers, 47 snags removed 646.68 Hydrographic surveys ..................................... 35,236.58 Operation and care of Yamhill Lock: Operation ............................................ 5,595.56 Maintenance and repair of grounds and structures . ... 5,204.70 Improvement and reconstruction; plans and specifications for gate reconstruction .............................. 732.75 Total costs for the fiscal year were $399,711.64, of which $388,- 178.63 was for maintenance, and $11,533.01 for operation and care. Expenditures were $403,686.35. Condition at end of fiscal year.-The existing project is ap- proximately 65 percent complete. The 8-foot channel between Portland and Oregon City and the 21/-to 31/2-foot channel between Oregon City and Albany were completed in 1939. The 21/2 to 31/ 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 Ore- gon City, and 31/2 feet from Oregon City to Corvallis. In Yamhill River, the controlling depth is 4 feet from the mouth to Yamhill lock and 2 feet from the lock to McMinnville. RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2475 Traffic is confined to towboats, log rafts, launches, and dredges. Between Oregon City and Pulp Siding (about 3 miles), and be- tween Oregon City and Portland, barges are used in the trans- portation of paper and wood-pulp products. The Yamhill lock and grounds are in fair condition, but the lock gates should be replaced. Repairs to the dam, which is in poor condition, are about 40 percent complete. The lock is used only for the passage of logs downstream, and the grounds to a considerable extent for recreational purposes. Total costs under the existing project, from Federal funds, have been $5,988,570, of which $615,169.74 was for new work, $5,274,903.97 for maintenance, and $98,496.29 for operation and care. Expenditures have been $6,001,507.83. In addition, the sum of $106,433.23 was expended between September 24, 1900, and June 30, 1935, on operation and care of works of improvement under the provisions of the permanent indefinite appropriations for such purposes. An additional sum of $7,500 was expended from contributed funds for maintenance, and $484,900 from emergency flood control funds for new work. Proposed operations.-The funds unexpended June 30, 1950, including accounts receivable, amounting to $72,791.03, plus an anticipated allotment of $313,000 for maintenance and $12,000.00 for operation and care, a total of $397,791.03, will be applied as follows: Accounts payable ...................... ................... $125.70 Maintenance: Dredging in Willamette River between Oregon City Cor- vallis and in Yamhill River between the mouth and Yam- hill Lock by Government plant, July to October 1950 and April to June 1951 ............................ 337,939.05 Repair of existing dikes, by hired labor, May to June 1951 6,000.00 Snagging in Willamette and Yamhill Rivers, by Government plant, July to October 1950 .......................... 3,000.00 Hydrographic surveys .................................. 27,619.00 Total maintenance ....... ........................ 374,558.05 Operation and care of Yamhill Lock: Operation ....................... ................... 7,020.00 Ordinary maintenance and repair ........................ 2,921.00 Improvement and reconstruction ........................ 13,166.28 Total operation and care .............................. 23,107.28 Total all work .................................... 397,791.03 The additional sum of $425,000 can be profitably expended during the fiscal year 1952 as follows: Maintenance consisting of dredging in Willamette and Yamhill Rivers between Oregon City and Corvallis, snagging in Willamette and Yamhill Rivers, repair of dikes, channel rectifications and hydrographic surveys, $400,000.

WILLAMETTE RIVER AT WILLAMETTE FALLS, OREG. Location.-The locks and the 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 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 water-power 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 ex- isting canal and lock at Willamette Falls: 1 Usable lock dimensions ............. Series of 4 locks, each 175 by 37 feet.

Terminal facilities.--The Crown Willamette Paper Co. has con- structed a timber wharf about 850 feet in length, extending to and supported by the concrete division wall built in the lock canal by the United States. Operations and results during fiscal year.-The existing canal and locks were in continuous operation throughout the fiscal year, except for the period from 8 a.m., July 1, to 4:30 p.m., July 10, inclusive when the locks were closed for repairs to gates and sills; from 10:30 a.m., November 5, to 9 p.m., November 5, for construction of a concrete pier at gate No. 5; from 4 p.m., Janu- ary 22, 1950, to 10:15 a.m., January 27, and from 8 a.m., Febru- ary 26, to 1 p.m., March 1, because of high water; and from 6:30 a.m. to 3 p.m. on April 4 for inspection of gate No. 6. The various items of maintenance (operation and care) and their costs were as follows: Operation of lock and canal ............................. $109,796.78 Ordinary maintenance and repair .......................... 18,970.32 Channel work, dredging in canal and locks ................ 375.80 Improvement and reconstruction: Installation of hydraulic gate opening device on east gates of locks ............................................ 9,502.79 Reconstruction of gate sills, gate guards, gate rails, wickets and wicket frames, and installation of conduits on floor of locks ............................. ... ...... ...... 41,056.76 Total costs for the fiscal year were $179,702.45, all for operation and care. Expenditures were $186,803.35. Condition at end of fiscal year.-The existing canal and locks were originally constructed by private interests in 1873 and purchased April 26, 1915, by the United States for $375,000. The dam is owned by private interests. The final report on the purchase and rehabilitation of the existing lock and canal was given in the annual report for 1923, when the project was reported 98 percent complete. No further work on that existing project was considered necessary. The controlling depth is 6 feet at low water on the miter sill of the upper lock. The existing lock and grounds are in fair condition and are in continuous operation except when 2478 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 flooded out by high water or undergoing repair. The facilities 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, 1938, and the River and Harbor Act of March 2, 1945; but plans and specifications for the work have been essentially completed. Total costs have been $2,014,757.53, of which $520,005.08 was for new work ($377,122.20 for purchase, and rehabilitation of existing lock and canal and $3,882.88 for new lock from River and Harbor funds and $139,000 for new lock from Flood Control funds), and $1,494,752.45 for maintenance (operation and care) from River and Har bor funds. Expenditures have been $2,467,097.32. In addition, $300,000 was expended from contributed funds for new work on existing canal and lock, and $452,109.76 was expended between April 16, 1915, and June 30, 1935, on the operation and care of works of the improvement under the pro- visions of the permanent indefinite appropriations for such pur- poses. Proposed operations.-The funds unexpended June 30, 1950, including accounts receivable, amounting to $5,701.15 plus an anticipated allotment of $157,000 for maintenance, a total of $162,701.15, will be applied as follows: Accounts payable ................. . ................. .... $2,693.82 Maintenance (operation and care) : Operation of canal and locks ............................ 110,020.33 Ordinary maintenance and repairs ...................... .19,087.00 Improvement and reconstruction, including hydraulic gate opening equipment, reconstruction of ramp, and recon- struction of gates Nos. 5 and 6 ....................... 30,900.00 Total maintenance ................................. 160,007.33 Total all work ................................... 162,701.15 The additional sum of $170,000 can be profitably expended during the fiscal year 1952 for maintenance (operation and care) of locks and canal including operation, ordinary maintenance and repair, and reconstruction of one lock gate.

COLUMBIA AND LOWER WILLAMETTE RIVERS BELOW VAN- COUVER, 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 2496, and of Willamette River, page 2472. 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 Vancouver, Wash., about 5 miles, with two turning basins of same depth at Vancouver, 800 feet wide and approxi- mately 2,000 and 3,000 feet long for the upper and lower basins, respectively, auxiliary channels 10 feet deep and 300 feet wide in the vicinity of Cathlamet, Wash., 30 feet deep and 300 feet wide in St. Helens (Oreg.) Channel, and 30 feet deep and 500 feet wide connecting the upper end of the St. Helens Channel with the main ship channel of the Columbia; 24 feet deep and 200 feet wide along the frontage of the town of Rainier, Oreg., extended at its upper 2480 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 and lower ends to deep water in the Columbia River, 8 feet deep and 150 feet wide from this depth in Columbia River through the old mouth of Cowlitz River to a point approximately 3,000 feet upstream from the present terminus of the harbor line; a channel from the Longview Port dock downstream along the pierhead line and past the Weyerhaeuser Timber Co.'s plant at Longview, to a connection with the main ship channel below Mount Coffin the downstream 2,400 feet of this channel to be 30 feet deep and 300 feet wide and the remainder to be 28 feet deep and 250 feet wide; construction of a small-boat mooring basin at Astoria, Oreg., to include a sheet-pile, sand-filled breakwater about 2,400 feet long with a 20-foot roadway along its full length, and steel-pile shore wings totaling about 1,460 feet in length; and for the construction of stone and pile dikes and revetments. The plane of reference in the estuary from the mouth to Har- rington Point is mean lower low water; thence to Portland and Vancouver, low water. The tidal range between mean lower low water and mean higher high water at the mouth of the Columbia is about 8 feet, and at Portland and Vancouver about 21/2 feet at low stages of the rivers. Extreme tidal ranges are about 13 feet and 3 feet, respectively. Annual freshets have but little effect on depths at the mouth of the Columbia; at Portland and Vancouver they average about 20 feet, while the highest known reached a stage of 33 feet above low water at Portland. The latest (1950) approved estimate of cost for new work, exclusive of amounts expended under previous projects and contri- buted funds, is $5,503,000. The latest (1948) approved estimate for annual cost of maintenance is $1,459,000.

Terminal facilities.-At Portland, Oreg., there are under public ownership three terminals for general cargo. Under private owner- ship, but open to the public on equal terms, are six general cargo, five grain and flour, eight lumber, one cement, one copra products, and nine fuel-oil and gasoline terminals, besides outfitting and repair wharves, sand and gravel and construction equipment wharves. There are five drydocks, one of 1,000-ton, one of 8,000- ton, two of 12,000-ton, and one leased from Department of the Navy for public use, of 14,000-ton capacity. There are three privately owned marine railways for handling small vessels and barges. There are two heavy lifts located in the port of Portland, one of 100-ton capacity on Municipal Terminal No. 1, and one of 150-ton capacity on locomotive crane dock. At Astoria, Oreg., there is a large municipal terminal with grain elevator and flour mill, and facilities for receiving oil pro- ducts by tanker. There are also private wharves used for receipt of fish, general merchandise, and the bunkering of fishing vessels. At Vancouver, Wash., below Interstate Bridge, there are two municipal terminal wharves. There are also several privately owned wharves for shipment of lumber, a fuel and gasoline termi- nal, and a privately owned grain elevator and wharf. At Kalama, Wash., there is a muncipal wharf for shipment of lumber, and a heavy lift of 100-ton capacity. 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 the shipment of lumber. A privately owned grain elevator for the shipment of grain and flour 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 150-ton capacity. At other small towns on the Columbia River, between Portland and Columbia River entrance, there are sufficient private facilities to accommodate the river vessels and fishing fleets, and at seven 2482 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 points there are large sawmill docks used entirely for the ship- ment of lumber in ocean-going carriers. These facilities, with the planned extensions, are considered adequate for the present needs of commerce. (For further details see Port Series No. 11, Corps of Engineers.) Local cooperation. Requirements of cooperation prior to 1945 have been fully complied with. The River and Harbor Act ap- proved March 2, 1945, provides, under modifications therein authorized (Longview auxiliary channel and improvement of old mouth of Cowlitz River), 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 improvements and their subsequent maintenance when and as required; hold and save the United States free from claims for damages resulting from the improvements; and dredge and maintain to a depth of at least 28 feet the area abutting the proposed channel opposite the wharf of the Weyerhaeuser Timber Co. at Longview, Wash. The act of July 24, 1946, authorizing the construction of a small-boat mooring basin at Astoria, Oreg., provides that local interests furnish as- surances to the United States that they will furnish free of cost all necesesary lands, easements, and rights-of-way for the new work and subsequent maintenance when and as required; provide mooring facilities within the basin, sewers, water and electric supply lines, and a public landing within suitable supply facili- ties open to all on equal terms. Assurances for the auxiliary channel in the vicinity of Long- view were approved on October 8, 1948; and dredging the area abutting the authorized channel opposite the wharf of the Weyer- haeuser Timber Co. has been completed with funds contributed by local interests. Assurances for the small-boat basin at Astoria were approved on November 4, 1947. Operations and results during fiscal year.-New work: The im- provement of the old mouth of Cowlitz River by dredging a chan- nel 8 feet deep and 150 feet wide from deep water in Columbia River through the old mouth of Cowlitz River to a point 3,000 feet upstream from the present terminus of the harbor line was initi- ated March 10 and completed March 18, 1950, by contract. A total of 71,965 cubic yards of material was removed. Construction of the Astoria, Oreg., small-boat mooring basin, initiated March 2, 1949, was completed during the fiscal year ex- cept for surfacing of a roadway on the breakwater. This roadway surfacing will be accomplished after local interests have completed construction of a shore-connecting ramp. Maintenance: Repairs to 30 dikes, initiated during the fiscal year 1949, were completed. Construction of 22 four-pile mooring dolphins was completed and repairs to additional existing pile dikes were initiated, but work postponed until low water season. Costs of dike repairs during the fiscal year were $20,077.70. Main- tenance dredging with Government plant and hired plant was done on all bars and in all channels where surveys indicated shoaling. Dredging operations in Columbia River resulted in the removal of 9,782,496 cubic yards of material at a cost of $1,121,501.66. A RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2483 total of 2,362,619 cubic yards of material was removed from Willamette River between the mouth and Broadway Bridge at a cost of $403,323.51. The removal of the accumulated material in Portland Harbor was completed. Hydrographic surveys in Columbia and Willamette Rivers were continued during the fiscal year at a cost of $115,656.46. Total costs for the fiscal year were $2,934,305.72, of which $1,273,746.39 were for new work and $1,660,559.33 for main- tenance. Expenditures were $2,903,058.15. In addition, $72,710 contributed funds were expended for new work. Condition at end of fiscal year.-The existing project is com- plete except for surfacing of a roadway on the breakwater of the Astoria, Oreg., small-boat basin. The channel project was com- pleted in 1933, except that a revision at Harrington Point was made in 1935. The dikes were completed in 1935 and the exten- sion of the Vancouver turning basin in 1939. Of the 145 dikes constructed on this project, 13 were repaired in 1946 and 1947, 22 during 1948, and 30 during 1949. The auxiliary channel in the vicinity of Longview was completed May 12, 1949, and the im- provement of the old mouth of Cowlitz River on March 10, 1950. The small-boat mooring basin at Astoria has been completed except for surfacing the roadway on the breakwater. The controlling depth at low water in Columbia River from its mouth to the mouth of Willamette River is 32 feet. Above the mouth of Willamette River, the Vancouver channel had a con- trolling depth of 30 feet, and in Willamette River from its mouth to Broadway bridge the controlling depth is 32 feet. Project depths are maintained throughout the year except during short shoaling periods following freshets, which generally occur in May, June, and July. In Columbia and Willamette Rivers, between the mouth and Broadway bridge at Portland, a draft of 32 feet at low tide and 35 feet at high tide is practicable throughout the year. In Colum- bia River, between the mouth of Willamette River and Vancouver, Wash., drafts of 26 and 28 feet at low and high tide, respectively, are practicable throughout the year.

LEWIS RIVER, WASH. Location.-This river rises in the Cascade Range in Washington, flows westerly and southwesterly 110 miles, and empties into the Columbia River about 88 miles from its mouth. (See U. S. Coast and Geodetic Survey Charts Nos. 6153 and 6154.) Previous projects.-The original project was adopted by the River and Harbor Act of March 3, 1899, and modified by the River and Harbor Act of June 13, 1902. For further details see page 2001. Annual Report for 1915, and page 1762, Annual Report for 1938. Existing project.-This provides for a low-water channel 6 feet deep and 50 feet wide to the mouth of the East Fork (33/4 miles) ; 4 feet deep and 50 feet wide on the East Fork from its mouth to La Center (3 miles) ; 4 feet deep and 50 feet wide on Lewis River (North Fork) and from East Fork to Woodland (21/2 miles), to be secured by dredging and by the construction of regulating works and for clearing the channel to Ariel (16 miles above Woodland). The maximum variation of water level due to tide ranges from about 3 feet at the mouth to 11/2 feet at La Center and zero at Woodland. During ordinary freshets a stage of 14 feet and, at extreme floods, a stage of about 24 feet is reached in the main river at Woodland, Wash. The estimate of cost for new work made in 1913 was $61,500 ex- clusive of amounts expended under previous projects. The latest (1948) approved estimated for annual cost of maintenance is $3,000. The existing project was adopted by the River and Harbor Act of March 4, 1913 (H. Doc. 28, 62d Cong., 1st sess.). For latest pub- lished map see page 3557 of Annual Report for 1904. Recommended modifications of project.-The Chief of Engineers has recommended that the project be modified by eliminating all work on the East Fork and on the North Fork above Woodland (H. Doc. 467, 69th Cong., 1st sess.). Terminal facilities.-At Woodland, on the Lewis River, and at La Center, on the East Fork, the terminals consisting of pile and timber structures are privately owned and are adequate for the existing commerce. 2486 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Operations and results during fiscal year.-Snagging in Lewis River from the mouth to Woodland was accomplished by Govern- ment plant and hired labor. A total of 137 snags were removed at cost of $4,136.91. Hydrographic surveys were made at a cost of $3,457.13. Total costs and expenditures for the fiscal year were $7,594.04 for maintenance. Condition at end of fiscal year.-The existing project was com- pleted in 1927. No maintenance dredging has been done since the project was completed and the channel is in poor condition. Snagg- ing during the fiscal year 1950 improved conditions, but some dredging is necessary, particularly at the mouth. Total costs and expenditures have been $110,809.80, of which $35,880.44 was for new work and $74,929.36 for maintenance. Proposed operations.-No work is scheduled for the fiscal years 1951 or 1952.

COWLITZ RIVER, WASH. Location.-This river rises in the Cascade Range in Washington, flows westerly and southerly about 120 miles, and empties in the Columbia River about 69 miles from the mouth. (See U. S. Coast and Geodetic Survey Chart No. 6153.) Previous projects.-Adopted by the River and Harbor Act of June 14, 1880. For further details see page 2000 of Annual Report for 1915 and page 1763 of Annual Report for 1938. Existing project.-This provides for a channel 4 feet deep at low water and 50 feet wide from the, mouth to Ostrander (9 miles), thence 21/2 feet deep and 50 feet wide to Castle Rock (10 miles), and thence 21/2 feet deep at low water and not less than 40 feet wide to Toledo (18 miles), to be secured by snagging, dredging, and regulating works. The water level, due to tides, varies from 4 feet at the mouth to zero at Ostrander. During ordinary freshets a stage of 20 feet, and at extreme floods a stage of 25 feet, is reached in the river at Kelso, Wash. The estimate of cost for new work, revised in 1912, was $39,100, exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $20,000. RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2487 The existing project was adopted by the River and Harbor Act of June 25, 1910 (H. Doc. 1167, 60th Cong., 2d sess., from the mouth to Castle Rock and H. Doc. 404, 61st Cong., 2d sess., from Castle Rock to Toledo). For the latest published map see House Document 1167, Sixtieth Congress, second session. Recommended modifications of project.-The Chief of Engineers has recommended that the project be modified by the elimination of all work above Castle Rock (H. Doc. 467, 69th Cong., 1st sess.). Terminal facilities.-Above Kelso the terminal facilities are limited to two log dumps. At Kelso there are a number of small private wharves and one public landing. Between Kelso and the mouth there are two private commercial wharves. These facilities are considered adequate for present commerce. Operations and results during fiscal year.-Maintenance dredg- ing with Government plant and hired labor removed a total of 92,470 cubic yards of material at a cost of $22,688.81. Emergency dredging to remove a shoal at the mouth was done with the con- tract dredge Washington. A total of 19,510 cubic yards of material was removed at a cost of $3,227.08. Hydrographic surveys were made at a cost of $3,177.15. Total costs and expenditures during the fiscal y ear were $29,093.04 for maintenance. Condition at end of fiscal year.-The existing project was com- pleted in 1913. The channel is maintained to the project depth of 4 feet between the mouth and Kelso. Above Kelso the channel is in poor condition, with a controlling depth at low water of 2 feet. Total costs and expenditures for the existing project have been $331,294.25, of which $32,907.62 was for new work and $298,386.63 for maintenance.

Coast and Geodetic Survey Chart No. 6152.) Existing project.-This provides for a channel 32 feet deep at low water, 300 feet wide in the entrance and to about the midpoint of its length, and generally 250 feet wide in the upper 1,800 feet. Low water is the plane of reference. The average tidal range dur- ing low-water conditions in Columbia River is about 5 feet. The estimated cost for new work revised in 1950 is $144,000. The latest (1950) approved estimate of the annual cost of main- tenance is $18,000. The existing project was authorized by the River and Harbor Act of August 26, 1937 (H. Doc. 79, 75th Cong., 1st sess.), and modified by the River and Harbor Act of May 17, 1950 (H. Doc. 134, 81st Cong., 1st sess.). Local cooperation.-TheRiver and Harbor Act of May 17, 1950, provides that 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, rights-of-way, and spoil- disposal areas, including necessary bulkheads, 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 works and susequent maintenance; and (3) provide and maintain, at their own expense, a channel 32 feet deep and 200 feet wide from the upstream terminus of the existing project to the upper end of the mill dock, an additional distance of approxi- mately 1,300 feet. Terminal facilities.-The only terminal is the privately owned wharf of the Shepard & Morse Lumber Co. There is no need at present for additional terminals. Operations and results during fiscal year.-Maintenance dredg- ing of the channel to project depth was accomplished by the Government pipe-line dredge Wahkiakum. A total of 69,700 cubic yards of material was removed at a cost of $9,267.09. Hydro- graphic surveys were made at a cost of $215.76. Total costs and expenditures during the fiscal year were $9,482.85. Condition at end of fiscal year.-The channel 28 feet deep and 200 feet wide, as originally authorized, was completed in 1930. No work has been done on the 32-foot channel which was authorized by the River and Harbor Act of 1950 as a modification of the ex- isting project. The channel is in good condition, but commerce and vessels must wait for tides to leave the channel when loaded. A survey, made February 14, 1950, showed a controlling depth of 261/2 feet. Total costs and expenditures have been $51,218.10, of which $16,276.19 was for new work and $34,941.91 for maintenance. Proposed operations.-An anticipated allotment of $14,932.34 will be applied to dredging channel to a depth of 28 feet and hydrographic surveys, all for maintenance. No work is scheduled in fiscal year 1952.

SKAMOKAWA CREEK, WASH. Location.-This creek rises in Wahkiakum County, in the south- western part of the, State of Washington, flows southwesterly and southerly about 10 miles, and empties into the Columbia River about 34 miles from the mouth. (See U. S. Coast and Geodetic Survey Chart No. 6152.) Existing project.-This provides for a channel 61/2 feet deep at low water and 75 feet wide between Steamboat and Brooks sloughs, about 1,600 feet. The tidal range between mean lower low water and mean higher high water is about 7 feet and the maximum variation of water level due to tides or freshets is about 12 feet. During ordinary freshets a stage of 9 feet and at extreme floods a stage of 12 feet is reached in the creek at Skamokawa, Wash. The estimate of cost for new work, made in 1919, was $2,400. The latest (1948) approved estimate for annual cost of mainte- nance is $4,800. The existing project was authorized by the River and Harbor Act of March 2', 1919 (H. Doc. 111, 63d Cong., 1st sess.). The latest published map is in the project document. Terminal facilities.-There are three privately owned wharves, one on Steamboat slough and two above Brooks slough, used for general freight and passenger purposes, and these are considered adequate for the present commerce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The, project was completed in 1920. The channel is in fair condition, but there has been some shoaling since the last maintenance dredging in November 1948, when controlling depth of 6 feet was obtained. Total costs and expenditures have been $37,743.57, of which $2,400 was for new work and $35,343.57 for maintenance. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952. 939127-51-vol. 2----67 2490 REPORT OF CHIEF OF ENGINEERS, U. S.

DEEP RIVER, WASH. Location.-This river is mainly a tidal slough of Grays Bay, Wash., an estuary on the north side of the Columbia River, about 20 miles from the mouth. The slough extends northerly about 4 miles from the northern end of Grays Bay, and the section above the head of the slough has several small tributaries (See U. S. Coast and Geodetic Survey Chart No. 6151.) Existing project.-This provides for a channel 8 feet deep at mean lower low water, 100 feet wide through the bars at the mouth of the river and the entrance thereto, and 60 feet wide in the river up to the town of Deep River. The tidal range at the mouth, between mean lower low water and mean higher high water, is about 8 feet and the extreme range about 13 feet. During ordinary freshets a stage of 9 feet and at extreme floods a stage of 14 feet is reached in the river at the town of Deep River, Wash. The estimate of cost for new work, revised in 1927, was $18,200. The latest (1948) approved estimate of annual cost of mainte- nance is $5,000. The existing project was adopted by the River and Harbor Act of March 3, 1925 (H. Doc. 218, 68th Cong., 1st sess.) There is no published map. Terminal facilities.-There is one privately owned wharf at the town of Deep River for general freight and passenger purposes which is considered adequate for the present commerce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The project was completed in 1928. The last maintenance dredging was done in 1933, and the latest survey made in 1944 showed a controlling depth of 4 feet from the mouth to mile 1, thence 2.5 feet to the town of Deep River. Local interests have reported shoaling and an accumulation of snags. The channel is used almost entirely for rafted logs, with an occasional barge using the waterway. Total costs and expenditures have been $27,820.06, of which $15,384.40 was for new work and $12,435.66 for maintenance. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952.

The channel enters the Columbia about 10 miles above its mouth and 4 miles below As- toria, Oreg. (See U. S. Coast and Geodetic Survey Chart No. 6151.) Existing project.-This,provides for a channel 30 feet deep and generally 200 feet wide extending from deep water in Columbia River to the railroad bridge at Warrenton, Oreg., a distance of 1.8 miles, for a turning basin of the same depth, a mooring basin 12 feet deep at mean lower low water at Warrenton, Oreg.; and for a channel 6 feet deep and generally 40 feet wide, with increased widths at log dumps and terminals, for a distance of 4500 feet, via cut-off channel, above the railroad bridge. Mean lower low water is the plane of reference. The tidal range between mean lower low water and mean higher high water is about 8 feet; the extreme tidal range is about 13 feet. The estimate of cost of new work revised in 1950 is $293,000. The latest (1948) approved estimate of cost for annual mainte- nance is $48,000.

Local cooperation.-Requirements contained in River and Har- bor Acts of July 3, 1930, and August 26, 1937, have been fully com- plied with. The River and Harbor Act approved June 30, 1948, Public Law 858, provides in connection with the mooring basin that before construction is initiated, responsible local interests give assurances 2492 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 satisfactory to the Secretary of the Army that they will (a) pro- vide without cost to the United States all lands, easements, and rights-of-way necessary for the construction of the project and subsequent maintenance thereof, (b) hold and save the United States free from damages due to the construction work, (c) main- tain project depth in the basin after completion, and (d) construct, maintain and operate the necessary mooring facilities and utilities within the, basin, including a public landing with suitable supply facilities, all of which shall be open to all on equal terms. Before adoption of the project, local interests and the port of Astoria constructed timber bulkheads and dredged the channel at a total cost of about $560,000. Terminal facilities.-The city of Warrenton owns a wharf with 300-foot frontage open to the public. One privately owned lumber mill wharf with 800-foot frontage is used for loading lumber ship- ments. One privately owned cannery wharf with 300-foot frontage is used for unloading fish, loading and unloading nets. One pri- vately owned boat yard has floats and moorage facilities for a maximum of 80 small boats. In the channel above the railroad bridge the facilities are the log dumps used by logtrucks. These facilities are considered adequate for present commerce. Operations and results during fiscal year.-Maintenance dredg- ing of the channel between the mouth and Prouty Mill, restoring project depth of 30 feet, was completed June 15, 1950. A total of 206,675 cubic yards of material was removed at a cost of $25,- 962.61. Hydrographic surveys were made at a cost of $1,137.39. Total costs and expenditures for the fiscal year were $27,100 for maintenance. Conditions at end of fiscal year.-Dredgingof the channel and turning basin was completed in 1930. No work has been done on the construction of the small-boat mooring basin at Warrenton. The project is 70 percent complete. There is a controlling depth of 30 feet in the channel and 10 feet in the turning basin. No recent surveys above the railroad bridge at Warrenton have been made. Total costs and expenditures have been $408,123.10, of which $130,119.35 was for new work and $278,003.75 for maintenance. Proposed operations.-No work is scheduled in fiscal years 1951 and 1952.

COLUMBIA RIVER BETWEEN CHINOOK, WASH., AND THE HEAD OF SAND ISLAND Location.-At the easterly end of Bakers (Baker) Bay, which is on the north side of the Columbia River near its mouth. (See U. S. Coast and Geodetic Survey Chart No. 6151.) Existing project.-This provides for a channel 8 feet deep and 150 feet wide, extending from the head of Sand Island to Chinook, Wash., a distance of about 4,000 feet, and the reinforcement and future maintenance of the existing pile and timber breakwater at Chinook. Mean lower low water is the plane of reference. The tidal range between mean lower low water and mean higher high water is about 8 feet and the extreme tidal range about 13 feet. The estimated cost of new work, made in 1938, was $25,000. The latest (1948) approved estimate of cost of annual maintenance is $18,000. The existing project was authorized by the River and Harbor Act of June 20, 1938 (Rivers and Harbors Committee Doc. 50, 75th Cong., 2d session.). The latest published map is in this docu- ment. Terminal facilities.-The only terminal is the wharf of the Chinook Packing Co., a portion of which is used as a public land- ing. There is no present need for additional terminals. Operations and results during fiscal year.-Maintenance dredg- ing of the channel was completed June 22', 1950, restoring project depth of 8 feet. A total of 68,433 cubic yards of material was re- moved at a cost of $9,088.31. Hydrographic surveys were made at a cost of $911.69. Total costs and expenditures for the fiscal year were $10,000 for maintenance. Conditions at end of fiscal year.-The project was completed in 1940. Repairs to the breakwater were completed in 1939 and the channel dredging in 1940. The channel is in good condition, with a controlling depth of 8 feet at mean lower low water. Total costs and expenditures have been $103,287.46, of which $40,000 was for new work and $63,287.46 for maintenance. Proposed operations.-An anticipated allotment of $4,958 for maintenance will be applied to dredging channel by Government plant and hired labor July 1950. No work is scheduled in fiscal year 1952.

The bay is separated from the river by Sand Island, a low-lying sand bar only a few feet above high-tide level. (See U. S. Coast and Geodetic Survey Chart No. 6151.) Existing project.-This provides for a main channel, 10 feet deep and 200 feet wide, extending through the easterly passage at Sand Island to the port of Ilwaco, a distance of about 5 miles; for a mooring basin 10 feet and 12 feet deep, about 20 acres in extent, located east of the port of Ilwaco dock, with protecting break- waters; and for a west channel 10 feet deep connecting the basin with deep water in Columbia River, with a width of 150 feet, increased to 200 feet for a distance of 2,000 feet at the southerly end. Mean lower low water is the plane of reference. The tidal range between mean lower low water and mean higher high water is about 8 feet, and the extreme about 13 feet. The approved estimate of cost for new work, revised to include the project modification authorized by the River and Harbor Act of 1950, is $956,700. The approved estimate of annual mainte- nance, revised in 1950, is $88,500.

Local cooperation.-The River and Harbor Act approved May 17, 1950, in connection with construction of the mooring basin and modification of the west channel provides: (a) That local inter- ests furnish free of cost to the United States all necessary lands, easements, rights-of-way, and spoil disposal areas for the new work and for its subsequent maintenance, when and as required; (b) hold and save the United States free from damages due to the construction works and their subsequent maintenance; (c) main- tain project depths in the mooring basin; (d) make the necessary changes in existing sewers; and (e) provide and maintain ade- quate terminal and mooring facilities within the basin, including a public landing with suitable supply facilities open to all on equal terms. Terminal facilities.-Terminalshave been constructed at Ilwaco along Holman waterway, 200 feet wide by 3,000 feet in length, and on a dredged basin 400 feet by 1,000 feet. The facilities consist of wharves, floats, ramps, and berths for oil barges and oil boats. The facilities are considered adequate for the present commerce. Operations and results during fiscal year.-New work: Hydro- graphic surveys and planning for an 1,800-foot extension to an RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2495 existing pile, timber, and stone dike at the westerly end of Sand Island were completed and the work advertised. Construction will be accomplished during the fiscal year 1951. Maintenance: Dredging in the westerly channel was started on June 22, 1950, and will be completed during the fiscal year 1951. A total of 126,695 cubic yards of material was removed at a cost of $22,637.27. Hydrographic surveys were made at a cost of $3,094.- 08. Total costs for the fiscal year were $28,205.35, of which $2,- 474 was for new work and $25,731.35 for maintenance. Expenditures were $22,389.71. Condition at end of fiscal year.-The existing project is 33 per- cent complete. The channel extending through the easterly passage at Sand Island was completed in 1934. Dredging of the west chan- nel, extending from deep water in Columbia River to the east channel near Ilwaco, was partly completed with military funds during June 1943 and August 1944, and was completed with proj- ect funds August 26, 1948. Construction of three spur dikes in connection with the west channel was completed September 30, 1948. Surveys, investigation, and plans and specifications cover- ing construction of an 1,800-foot extension to one of these dikes has been completed and the work advertised. No work has been done on the mooring basin authorized as a project modification by the River and Harbor Act approved May 17, 1950. Total costs have been $515,271.63, of which $326,091.57 were for new work and $189,180.06 for maintenance. Expenditures have been $509,455.99. Proposed operations.-The funds unexpended June 30, 1950, including accounts receivable amounting to $93,391.82, plus antici- pated allotments of $5,315 for new work, and $24,577.33 for main- tenance, a total of $123,284.15, will be applied as follows: Accounts payable .......................................... $6,637.27 New work: Construction of an 1,800-foot extension to an existing pile timber and rock-spur dike by contract July to October 1950 ............................ ................... .. 87,800.90 Maintenance: Dredging easterly channel to project depth of 10 feet and west channel to project depth of 8 feet by Govern- ment pipe-line dredge during July 1950 .................. 28,845.98 Total all work .................................... . 123,284.15 The additional sum of $50,000 can be profitably expended dur- ing the fiscal year 1952 for maintenance, consisting of channel dredging and hydrographic surveys. 2496 REPORT OF CHIEF OF ENGINEERS, U.

COLUMBIA RIVER AT THE MOUTH, OREGON AND WASHINGTON Location.--This river rises in British Columbia, through which it flows for 425 miles. It enters the United States in northeastern Washington, flows southerly to the mouth of Snake River, thence westerly between Oregon and Washington, and empties into the Pacific Ocean 645 miles north of San Francisco Bay and 160 miles south of the Straits of Juan de Fuca. The total length of the river is 1,210 miles. (See U. S. Coast and Geodetic Survey Charts Nos. 5902, 6151, 6152, 6153, 6154, 6155, and 6156; also Geological Sur- vey map of Washington.) Previousproject.-Adopted by the River and Harbor Act of July 5, 1884. For further details see page 1999 of Annual Report for 1915 and page 1740 of Annual Report for 1938. Existing project.-This provides for a channel across the bar 40 feet deep at mean lower low water and of suitable width (not less than one-half mile), to be secured by dredging and by converging rubble-mound jetties, the south jetty being about 7 miles and the north jetty about 21/2 miles long, terminating 2 miles north of the end of the south jetty. Mean lower low water is the plane of refer- ence. The tidal range on the bar between mean lower low water and mean higher high water is about 8 feet, and the extreme tidal range is about 13 feet. The estimate of cost for new work was as follows: For the south jetty extension revised in 1909, $8,014,164; for the north jetty, re- vised in 1913, $5,966,573; and for remodeling and operating the dredge, made in 1905, $250,000; a total of $14,230,737, exclusive of amounts expended under previous projects. The latest (1948) approved estimate for annual cost of maintenance is $336,000 except for the repairs to jetties. Jetty maintenance is done only at intervals of several years and is covered by special allotments. The existing project was authorized by the River and Harbor Act of March 3, 1905, making final provision for the south jetty, RIVERS AND HARBORS--PORTLAND, ORE., DISTRICT 2497 the construction of the north jetty, and dredging (H. Doc. 94, 56th Cong., 1st sess., and Annual Report for 1903, p. 2275). The con- struction of the north jetty was approved July, 29, 1910, and a modification of its alignment December 27, 1913. The latest pub- lished map is in the Annual Report for 1921 opposite page 1868. Local cooperation.-Theexisting project contains no conditions requiring local cooperation. However, during 1914 the port of Portland contributed $475,000 and the port of Astoria $25,000 to this improvement. These amounts have been expended, the greater part having been applied to the purchase of stone for the north jetty. Terminal facilities.-Forterminal and transfer facilities see re- port on Columbia and Lower Willamette Rivers. Operations and results during fiscal year.-Surveys and inves- tigations in connection with the repairs to Sand Island dikes and revetments were made during the fiscal year at a cost of $4,988.88. Repairs to the drainage sewer at Hammond, Oreg., were completed at a cost of $10,222.20. Maintenance of warehouse, fences and structures at Fort Stevens was continued and costs for this work were $12,609.44. The U. S. hopper dredge Kingman removed a total of 927,176 cubic yards of material from the bar at Clatsop Spit at a cost of $75,598.14. Costs of hydrographic surveys made during the fiscal year were $14,300.87. Total costs for the fiscal year were $117,719.53 for maintenance. Expenditures were $118,585.98. Condition at end of fiscal year.-The existing project was com- pleted in 1918. The jetties are in good condition. Storms have damaged the enrockment on Sand Island and have broken through the narrow portion of the island about 2 miles from the east end. A survey made in August 1949 showed a controlling depth in the entrance channel of 42 feet at mean lower low water except at Clatsop Spit, where the controlling depth for the right quarter of the channel was 391/2 feet. Total costs under the existing project from Federal funds have been $22,253,331.33, of which $11,357,506.35 was for new work and $10,895,824.98 for maintenance. Total expenditures have been $22,254,078.72. In addition, $475,000 and $25,000 were contributed by the ports of Portland and Astoria respectively and expended for new work. Proposed operations.-The funds unexpended June 30, 1950, including accounts receivable amounting to $197,695.53, plus an anticipated allotment of $185,600, a total of $383,295.53, will be applied for maintenance as follows: Accounts payable .......................................... $302.25 Hydrographic surveys ......... ............................ 10,764.28 Real estate audit .......................................... 687.00 Maintenance of office, warehouses, fences and structures at Fort Stevens .............................................. 15,000.00 Dredging in entrance channel with hopper dredge Kingman .... 115,102.00 Placing revetment and construction of a stone dike at westerly end of the upper portion of Sand Island by existing contract 211,440.00 2498 REPORT OF CHIEF OF ENGINEERS, U.

TILLAMOOK BAY AND BAR, OREG. Location.-This bay is located on the Oregon coast about 50 miles south of the mouth of Columbia River. (See U. S. Coast and Geodetic Survey Charts Nos. 5902 and 6112.) Previous project.-Adopted by River and Harbor Acts of August 11, 1888, and July 13, 1892. For further details see page 1989 of Annual Report for 1915, and page 1474 of Annual Report for 1936. Existing project.-This provides for a jetty about 5,700 feet long on the north side of the entrance; for a channel through the bar 18 feet deep and of such width as can be practically and economically obtained; for a channel 200 feet wide and 18 feet deep from deep water in the bay to Miami Cove; for initial dredg- ing of a small-boat basin and an approach thereto at Garibaldi, Oregon, to a depth of 12 feet; for a channel to Hobsonville, 200 feet wide and 16 feet deep, with a turning basin 500 feet wide at Hobsonville, and regulating works as needed. The mean of the higher high waters above the plane of reference and the extreme tidal range at the entrance are 7.4 feet and about 13 feet, respectively. The estimate of cost for new work revised in 1950 is $693,450, exclusive of contributed funds. The latest (1948) approved esti- mate for annual cost of maintenance is $28,000 for entrance and bay channels.

Local cooperation.-The River and Harbor Act approved June 30, 1948, in connection with the authorization of small-boat basin at Garibaldi provides, (a) that local interests furnish all necessary easements, rights-of-way, and spoil-disposal areas, both for new work and maintenance, and (b) agree to maintain necessary depths in the mooring basin proper, to construct, maintain, and operate necessary mooring facilities and utilities within the basin, including a public landing with suitable supply facilities, open to all on equal and equitable terms, and (c) to hold and save the United States free from any claim for damages which might re- sult from execution of the work. The River and Harbor Act of March 3, 1925, provides that no work is to be done in the Hobsonville Channel until assurance is given that a mill of substantial capacity will be erected in the vicinity of Hobsonville.. This condition has not been complied with. All other prescribed conditions of local cooperation have been fully complied with except for requirements for Garibaldi Channel. Terminal facilities.-At Garibaldi there is a privately owned wharf and a publicly owned float landing suitable for small boats. The existing facilities are considered adequate for present com- merce. Operations and results during fiscal year.-Maintenance dredg- ing on the bar and channel by the. U. S. hopper dredge Pacific dur- ing May 1950 resulted in restoring project depth of 18 feet on the bar and 17 feet in channel to Miami Cove. A total of 191,943 cubic yards of material was removed at a cost of $51,537.24. Hydro- graphic surveys of the bar and channel were made at a cost of $3,- 492.76. Total costs and expenditures for the fiscal year were $55,030 for maintenance. Condition at end of fiscal year.-The existing project is 94 per- cent complete. The jetty was completed in 1933 and is in poor condition, with the outer 800 feet below low-water level. The re- maining work required to complete the project consists of dredg- ing the Hobsonville Channel and turning basin, which work will not be done until navigation requires deeper water, and dredging a small-boat basin and connecting channel at Garibaldi. The con- trolling depth on the bar and in the channel to Miami Cove is 18 feet at lower low water. 2500 REPORT OF CHIEF OF ENGINEERS, U. S.

DEPOE BAY, OREG. Location.-This harbor is located on the Oregon coast, 100 miles south of the mouth of Columbia River. (See U. S. Coast and Geo- detic Survey Chart No. 5902.) Existing project.--This provides for a breakwater north of the entrance, for an entrance channel 8 feet deep and 30 feet wide, and for an inner basin 350 feet by 750 feet, 8 feet deep, with retaining wall along the easterly side. Mean lower low water is the plane of reference. The mean of the higher high water and the extreme rise at the entrance above the plane of reference are 7.8 feet and about 11.5 feet, respectively. The latest (1950) approved estimate of cost for new work is $474,000. The latest (1948) approved estimate for annual cost of maintenance is $15,000. The River and Harbor Act of August 26, 1937 (H. Doc. 202, 75th Cong., 1st sess.), authorized construction of an inner basin 375 feet long, 125 feet wide, and 5 feet deep, with entrance chan- nel of same depth and 30 feet in width. The River and Harbor Act of March 2, 1945 (H. Doc. 350, 77th Cong., 1st sess,), modified RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2501 the project to provide for the existing project as described. The latest published map is in this document. Local cooperation.-Provisionsof the River and Harbor Act ap- proved August 26, 1937, have been fully complied with except for the construction of a public terminal. Under the provisions of the River and Harbor Act approved March 2, 1945, 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 improvements and their subsequent maintenance, when and as required, hold and save the United States free from claims for damages, resulting from the improvements, and save and hold free for use of the public as a roadway, promenade, or landing, a strip at least 60 feet wide along the easterly side of the retaining wall for its full length. Terminal facilities.-Terminal facilities consist of three perma- nent landings and several floats, just inside the entrance and east of the highway bridge, privately owned and used by operators of excursion and fishing boats. Operations and results during fiscal year.-New work: Excava- tion of the entrance channel to a depth of 8 feet and enlargement and deepening of the basin to a depth of 8 feet and the construc- tion of a retaining wall along the easterly side and a breakwater north of the entrance were started by contract on April 17, 1950. A rock and earth cofferdam across the entrance channel has been constructed and dewatering of the basin is complete. Foundation excavation for the retaining wall is underway. The contract work on the modified project is 22 percent complete. Maintenance: Maintenance dredging in the entrance and basin during July 1949 removed a total of 6,220 cubic yards of mate- rial at a cost of $2,302.15. Total costs for the fiscal year were $50,164.18, of which $47,- 862.03 was for new work and $2,302.15 for maintenance. Expenditures were $19,275.69. Condition at end of fiscal year.-Dredging of the basin and en- trance channel to a depth of 5 feet as originally authorized was completed in 1939. Excavating the enlarged basin and entrance channel to a depth of 8 feet and construction of the retaining wall and the breakwater at the entrance authorized by Rivers and Har- bors Act of 1945 was started April 17, 1950, by contract and is 22 percent complete. The project is 23 percent complete. Total costs have been $169,069.57, of which $79,228.61 were for new work and $89,840.96 for maintenance. Expenditures have been $138,442.87. Proposed operations.-The funds unexpended June 30, 1950, amounting to $333,359.28, plus an anticipated allotment of $5,785, a total of $339,144.28, will be applied as follows: 2502 REPORT OF CHIEF OF ENGINEERS, U.

YAQUINA RIVER, OREG. Location.-This river rises in the Coast Range, flows about 50 miles in a westerly direction, and empties into Yaquina Bay, on the Oregon coast. (See U. S. Coast and Geodetic Survey Charts Nos. 6058 and 5802.) Existing project.-This provides for two controlling half-tide dikes of piling, brush, and stone, each about 1,100 feet long (con- structed by local interests), and for a channel 10 feet deep and generally 150 feet wide in Yaquina River and 200 feet wide in Depot Slough, extending from the town of Yaquina to Toledo, about 9 miles. Mean lower low water is the plane of reference. The mean of the higher high waters above the plane of reference and the ex- treme tidal ranges under ordinary conditions at the mouth of the river are 8.1 feet and about 12 feet, and the same at Toledo. Freshet heights are about 12 feet at the mouth of Depot Slough. The estimate of cost for new work. made in 1911, was $72,000, including $43,200 contributed by local interests. The latest (1948) approved estimate for annual cost of maintenance is $10,000. The existing project was adopted by the River and Harbor Act of March 4, 1913, House Document 519, Sixty-second Congress, second session. The latest published map is in that document. Local cooperation.-Fully complied with. Terminal facilities.-At Yaquina, at the mouth of the river, RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2503 which is also the head of the bay, there is a small wharf of about 50-foot frontage. The port of Toledo has a public wharf in Depot Slough at Toledo, with frontage of about 600 feet. The city of Toledo also has a public wharf of about 50-foot frontage on Depot Slough built to accommodate small motorboats. There are also at Toledo two privately owned slips having special facilities for transferring lumber to lighters. These terminals are considered adequate for present commerce. Operations and results during fiscal year.-Removal of snags from the channel during August 1949 by rented plant restored the channel to navigation requirements at a total cost and expendi- ture of $81.44 for maintenance. Condition at end of fiscal year.-The project was completed in 1914. No recent surveys have been made, but shoaling has been reported by two boat operators. Total costs and expenditures have been $105,431.28, of which $28,800 was for new work and $76,631.28 for maintenance. In addition, $46,200 was expended; $43,200 for new work and $3,000 for maintenance, from contributed funds. Proposed operations.-No work is scheduled for the fiscal years 1951 or 1952.

YAQUINA BAY AND HARBOR, OREG. Location.-This bay is located on the Oregon coast, 115 miles south of the mouth of the Columbia River. (See U. S. Coast and Geodetic Survey Charts Nos. 5802 and 6058.) Previous projects.-The River and Harbor Act of June 14, 1880, provided for the improvement of the entrance. Subsequent proj- ects were adopted by River and Harbor Acts of June 3, 1896, June 6, 1900, and March 3, 1905. For further details see the Annual Report for 1893, part 4, page 3314, House Document 68, Fifty- fourth Congress, first session, and the Annual Report for 1938, page 1736. Existing project.-This provides for two high-tide rubble- mound jetties at the entrance, 1,000 feet apart at their outer ends; the north jetty to be 4,700 feet and the south jetty to be 5,800 feet in length; for a spur jetty on the channel side of the south jetty 2504 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 4,700 feet from its sea end, 800 feet in length; for five groins chan- nelward from the south jetty; insofar as the rock bottom will allow for a channel 26 feet deep and of suitable width across the entrance bar for a channel 20 feet deep and 300 feet wide from the outer end of the jetties upstream and along the south side of the bay a distance of about 2 miles to McLean Point with a turning basin at the upstream end 22 feet deep, 1,000 feet wide and 1,200 feet long; for a channel 18 feet deep and 200 feet wide from the 20-foot channel at about Mile 1, along the city docks at Newport, thence upstream to the abandoned railroad terminus at Yaquina, a distance of about 41/2 miles; and for a small-boat mooring basin at Newport, Oreg., by construction of a breakwater about 2,650 feet long and a shore wing about 400 feet long, and initial dredg- ing in the mooring basin to a depth of 10 feet. Mean lower low water is the plane of reference. The mean of the higher waters above the plane of reference and the extreme tidal range at the entrance and at the head of the bay are 8.1 feet and 12' feet, respectively. The latest (1950) approved estimate of cost for new work is $2,- 250,000. The latest (1946) approved estimate for annual cost of maintenance dredging in the bay and entrance is $87,500. The latest (1937) approved estimate of cost for maintenance of the north jetty is $12,000 annually to be applied at intervals of sev- eral years. There is no approved estimate for maintenance of the south jetty. The existing project was authorized by the following River and Harbor acts: Acts Work authorized Documents June 14, 1880 For improvement of the entrance_----------------Annual Report, 1881, p. 2589.

Local cooperation.-All requirements of local cooperation for work authorized prior to 1945 have been fully complied with. The River and Harbor Act approved March 2, 1945, provides that local interests furnish assurances that they will provide adequate terminal facilities open to all on equal and equitable terms, furnish free of cost to the United States all spoil-disposal areas necessary for the improvements and their subsequent maintenance, when and as required, and hold and save the United States free from claims RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2505 for damages resulting from the improvements. The act of July 24, 1946, provides that local interests furnish free of cost to the United States all lands, easements, rights-of-way, and spoil-dis- posal areas required for the construction of the project; furnish assurances satisfactory to the Secretary of the Army that they will maintain necessary depth in the basin; construct, maintain, and operate necessary mooring facilities and utilities within the basin, including a public landing with suitable supply facilities open to all on equal terms; and hold and save the United States free from damages due to the improvement. Assurances were approved November 14, 1947, and some mooring facilities have been constructed within the basin. Terminal facilities.---At McLean Point, on the north side of the bay, about 2 miles from the entrance, the Yaquina Bay Dock & Dredging Co. dock has a frontage of 630 feet with facilities for storage and loading lumber, open to all on equal terms. On the south side of the bay, about a mile and a half above the entrance, the C. D. Johnson Lumber Co. maintains private dolphins with a frontage of 700 feet for loading from barges. The port of New- port has a public wharf with 400 feet of frontage for handling of fishing boats. In addition, the port of Newport maintains about 500 feet of float landings for use of small seagoing fishing vessels. Operations and results during fiscal year.-New work: The re- moval of the remaining pinnacles from between the jetties to pro- vide project depth of 20 feet was initiated in June and will be complete in September 1950. This work being accomplished by hired labor and leased equipment is approximately 18 percent com- plete. Maintenance: Dredging on the bar and entrance channel by U. S. hopper dredge Pacific was done during July, August, and September 1949, and June 1950. A total of 272,142 cubic yards of material was removed at a cost of $74,806.65. Hydrographic surveys were made at a cost of $4,344.89. Total costs for the fiscal year were $92,447.26, of which $13,- 295.72 were for new work and $79,151.54 for maintenance. Expenditures were $63,335.64. Condition at end of fiscal year.-The existing project is 96 per- cent complete. Restoration of the jetties was completed in 1934 and the extension to the north jetty in 1940. Both jetties are in fair condition. The main channel from the outer ends of the jetties to McClean Point, 20 feet deep and 300 feet wide, with turning basins at the upstream end, and the channel 18 feet deep and 200 feet wide from the 20-foot channel at mile 1 along the city dock at Newport, thence upstream to the abandoned railroad terminus at Yaquina and the small boat mooring basin at Newport, were completed during the fiscal year 1949, except for a small area between the jetties, where pinnacles were encoun- tered and depths of from 17 to 19 feet were obtained. Removal of these pinnacles is underway and will be completed in June 1951. Completion of this work will complete the existing proj- ect. The controlling depth on the bar is 27 feet for a width of 300 feet. 939127-51-vol. 2---68 2506 REPORT OF CHIEF OF ENGINEERS, U. S.

SMITH RIVER, OREG. Location.-This river rises in the Coast Range in southern Ore- gon, flows about 40 miles in a general westerly direction to join Umpqua River opposite Reedsport, about 11 river-miles from the ocean. The course of the river meanders to such an extent that its total length is about 70 miles. The lower 23 miles is tidal. The section of the river included in this project is the lower 20.8 miles. The head of navigation is Sulphur Springs Landing, mile 20.8 (See U. S. Coast and Geodetic Survey Chart No. 6004.) Existing project.-This provides for a channel 6 feet deep at mean lower low water and 100 feet wide from the mouth of the river to the mouth of North Fork, and thence 4 feet deep at mean lower low water and 75 feet wide to Sulphur Springs Landing with a passing place 125 feet wide and 800 feet long in the vicinity of the mouth of North Fork. RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2507 The plane of reference is mean lower low water. The average range of the tide at the mouth is about 7 feet between higher high water and lower low water, and at the head of navigation (mile. 20.8) the tidal range is about 4 feet. The estimate of cost for new work revised in 1950 is $153,000. The latest (1946) approved estimate for annual cost of mainte- nance is $11,500. The existing project was authorized by the River and Harbor Act approved June 30, 1948, Senate Document 94, Eightieth Congress, first session. The. latest published map is in the project document. Local cooperation.-The River and Harbor Act approved June 30, 1948, requires that local interests agree to (a) furnish without cost to the United States all lands, easements, rights-of-way, and spoil-disposal areas for the new work and subsequent maintenance when and as required, (b) hold and save the United States free from damages due to construction and maintenance of the im- provement, and (c) construct and maintain terminal facilities as may be necessary to meet the needs of commerce, open to all on equal terms. Terminal facilities.-The only terminal facilities on Smith River are privately owned landing floats. In the lower portion of the river there are several booms and rafting grounds for the collec- tion of logs for subsequent movement to mills downstream. Ample space exists along the lower sections of the river for the develop- ment of terminal sites, should their need arise. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done. Proposed operations.-No work is contemplated during the fiscal year 1951 or 1952'. 25. UMPQUA RIVER, OREG. Location.-This river rises in the Cascade Range, flows west- erly about 120 miles, and empties into the Pacific Ocean 180 miles south of the mouth of the Columbia River and 465 miles north of San Francisco Bay. (See U. S. Coast and Geodetic Survey Charts Nos. 5802 and 6004.) Previousprojects. Adopted by River and Harbor Act of March 3, 1871, and modified in 1886. For further details see page 2967 of Annual Report for 1898, and page 1732 of Annual Report for 1938.

Recommended modification of the project.-Senate Document 133, Eighty-first Congress, second session, recommends that the existing project for Umpqua River, Oreg., be modified to provide for a channel in Schofield River, 12 feet deep at mean lower low water, generally 100 feet wide from its confluence with Umpqua River to a point 0.5 mile below the first railroad bridge, a distance of 2 miles, the entrance to be widened to 300 feet in a distance of 500 feet, at an estimated cost to the United States of $41,000 for new work and $7,000 annually for maintenance in addition to that now required; provided, 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 when and as required; and hold and save the United States free from damages due to the con- struction and maintenance of the project. Local cooperation.-Requirements of local cooperation for all work authorized prior to 1945 have been fully complied with and approved. RIVERS AND HARBORS--PORTLAND, ORE., DISTRICT 2509 Under the provisions of River and Harbor Act approved March 2, 1945, State or other local interests are required, for the Winches- ter Bay channel, to furnish free of cost to the United States suit- able areas for spoil disposal for initial work and subsequent main- tenance, when and as required, and hold and save the United States free from claims for damages resulting from the improve- ments; 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. For the Gardiner channel local interests are to furnish assurances that the Gardiner mill will be operated to produce an average daily output of 100,000 feet board measure for 300 days per year; that the mill wharf or other suitable wharf will be open to all on equal and reasonable terms; and that local interests furnish free of cost to the United States, when and as required, all lands, easements, and rights-of way and spoil-disposal areas for the initial work and for subse- quent maintenance, and hold and save the United States free from claims for damages resulting from the improvement. Assurances in connection with Gardiner channel were approved December 26, 1947. Assurances in connection with Winchester Bay channel have not yet been requested. 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 one wharf with 456 feet of water frontage and another with about 75 feet of water frontage which has not been used generally for commercial ship- ping. At Winchester Bay, there, is a public landing float with a wooden pile-and-timber shore approach, and a privately owned wharf used exclusively for the receipt of fish and marine products. The existing terminals are considered adequate for present com- merce. Operations and results during fiscal year.-Maintenance: Dredg- ing on the bar and in entrance channel was done by the hopper dredges Pacific and Michie during August and September 1949. A total of 150,058 cubic yards of material was removed at a cost of $43,526.25. Maintenance dredging in the channel from mile 4.4 to Reedsport by a contract dredge was started October 10, 1949, and completed February 28, 1950. A total of 866,400 cubic yards of material was removed at a cost of $209,789.70. Hydrographic surveys were made at a cost of $17,424.29. Model studies of the south jetty were completed by the U. S. Waterways Experimental Station at Vicksburg at a cost for the fiscal year of $173.25. Plans and specifications for construction of a training jetty 5,550 feet long and generally parallel to the entrance channel were completed at a cost of $2,499.23, and a continuing contract for the work was awarded. Construction under this contract was initiated January 23, 1950, with the driving of piling for the jetty. Placing of jetty rock was started on May 9, 1950, and 60,000 tons 2510 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 of rock were placed during the fiscal year. Total costs for the jetty contract, including Government cost for the fiscal year, were $303,357.43. Total costs for the fiscal year were $576,770.15 for maintenance. Expenditures were $593,813.77. In addition, $75,000 was expended from Federal funds for new work which were originally expended from advanced funds and reimbursed during the fiscal year 1950 by M. & I. Funds, the costs and expenditures of which were re- ported in the 1948 annual report. Conditions at end of fiscal year.-The existing project is 97 per- cent complete. The north jetty was completed in 1940. The exten- sion to the south jetty was completed in 1938, and dredging of a 22-foot channel from the mouth of the river to Reedsport was completed in 1941. The north jetty was reconstructed in 1942 and is in good condition. The south jetty is in fair condition except that about 1,000 feet of the outer end has been beaten down to low water level. Improvement to the south jetty by the construction of a training jetty generally parallel to the entrance channel is approximately 38 percent complete. This work, under construc- tion by continuing contract, is scheduled for completion March 18, 1951. The controlling depth at the close of the fiscal year was 19 feet on the bar, 20 feet from the mouth to Reedsport, and 20 feet in the Gardiner channel and turning basin. No work has been done on the Winchester Bay channel and mooring basin. Total costs under the existing project from Federal funds have been $4,839,774.22, of which $2,591,206.06 was for new work and $2,248,568.16 for maintenance. Expenditures have been $4,857,- 455.18. In addition, $276,500 was expended from contributed funds for new work. Proposed operations.-The funds unexpended June 30, 1950, including accounts receivable amounting to $310,629.73, plus an anticipated allotment of $976,165.09 during fiscal year 1951, a total of $1,286,794.82 will be applied as follows: Accounts payable .................................... $152,361.80 New work: Final costs of dredging of Gardiner Channel and Turning Basin accomplished in fiscal year 1949 and reported as costs in fiscal year 1951 ............................ 14,605.09 Maintenance: Completion of improvement of South Jetty by existing continuing contract ................................. 1,060,895.93 Dredging on the bar and in the bay channel by a seagoing hopper dredge during August and September 1950 .... 56,293.00 Repair of pile dike at mile 5.8 by hired labor ......... 972.00 Real estate audit ..................................... ..........

COOS AND MILLICOMA RIVERS, OREG. Location. The south fork and Millicoma Rivers rise in the coast range in southern Oregon, flow in a generally western direction, and join to make Coos River, 5.3 miles above the mouth of Coos River in Coos Bay. (See U. S. Geological Survey, Coos Bay quad- rangle). Existing project.-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 ex- treme tidal ranges under ordinary conditions at the mouth of the 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. 2512 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 The estimate of cost of new work, revised in 1950 is $440,000. The latest (1948) approved estimate for annual cost of mainte- nance is $27,000. 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.-TheRiver and Harbor Act of June 30, 1948, Public Law 858, provides that local interest (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 improvements. Terminal facilities.-There are several small privately owned wharves and landing places on the rivers that are used by small launches. There are no publicly owned wharves. The existing term- inal facilities are considered adequate for present commerce. Operationsand results during fiscal year.--A total of 310 snags were removed from the channel by hired labor and rented equip- ment. Total costs for the fiscal year were $7,857.92 for maintenance.. Expenditures were $7,761.60. Condition at end of fiscal year.-The originally authorized proj- ect, 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 gen- erally 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 and expenditures have been $93,154, of which $8,000 was for new work and $85,154 for maintenance. Proposed operations.-No funds are available and no work is scheduled for the fiscal year 1951, or 1952.

COOS BAY, OREG. Location.-On the Oregon coast 200 miles south of the mouth of Columbia River and 445 miles north of San Francisco Bay. It is about 13 miles long and 1 mile wide, with an area at high tide of about 15 square miles. (See U. S. Coast and Geodetic Survey Charts Nos. 5802 and 5984.) Previous projects.-Adopted by River and Harbor Acts of March 3, 1879, September 19, 1890, and August 18, 1894. For fur- ther details see page 1987 of Annual Report for 1915, and page 1728 of Annual Report for 1938. Existing project.-This provides for two rubble-mound, high- tide jetties at the entrance; a channel across the outer bar 40 feet deep at mean lower low water, and of suitable width with dimen- sions reduced gradually to Guano Rock; a channel 30 feet deep at mean lower low water and generally 300 feet wide thence to the mouth of Isthmus slough; turning basins of the same depth and 1,000 feet long and 600 feet wide opposite Coalbank slough and at the city of North Bend; anchorage basins 600 feet wide by 2,000 feet long at mile 3.5 and near mile 7; a channel 22 feet deep and 150 feet wide from Smiths Mill (mouth of Isthmus slough) to Millington, a mooring basin, about 500 feet by 900 feet, for small boats at Charleston, with a connecting channel, 10 feet deep and 150 feet wide, to deep water in Coos Bay, and the construction of a protecting breakwater and a bulkhead. The plane of reference is mean lower low water. The mean of the higher high waters above the plane of reference and the ex- treme tidal range at the entrance are 7 feet and about 11 feet, respectively, and at Coos Bay 7.3 feet and 11 feet, respectively. The estimate of cost for new work, revised in 1950, is $8,000,- 000 exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $654,500, not including repairs to jetties.

ARMY, 1950 Local cooperation.-The River and Harbor Act of July 24, 1946, provided that local interests give assurances satisfactory to the Secretary of War that they will: (a) Furnish free of cost to the United States necessary spoil-disposal areas for new work and subsequent maintenance as and when required; and (b) construct and maintain any additional terminal facilities necessary to the full use of the port, such facilities to be open to all on equal terms. Assurances of local cooperation were approved by the Secretary of the Army on November 4, 1947. The River and Harbor Act of June 30, 1948, in connection with Charleston Channel, provides that local interests (a) 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; (b) agree to construct, maintain, and operate adequate mooring facilities within the basin, and a public landing with suitable utility and supply facilities, without profit and open to all on equal and equitable terms; (c) maintain the bulkhead and maintain project depths within the mooring basin; (d) agree to hold and save the United States free from any claims for dam- ages which might result from execution of this improvement; (e) contribute $40,800 to defray one-half of the estimated cost of constructing the bulkhead; and (f) hold for the free use of the public as a roadway, promenade, or landing, 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. Assur- ances have not be requested. Terminal facilities.-At North Bend there are a municipal wharf 389 feet long fronting on the channel and about 1,400 feet of privately owned mill wharves. At Coos Bay there are a priv- ately owned wharf with a frontage of 860 feet, open to the public on equal terms; several small landings for fishing boats and har- borcraft; three oil-receiving docks in the vicinity; and two saw- mill wharves, about 1 mile above Coos Bay at Bunker Hill, for shipment of lumber. At Empire there is a privately owned lum- ber wharf with a frontage of 410 feet, and there is another one with a frontage of 500 feet, located 11/2 miles below. These facili- ties are considered adequate for existing commerce. At Charleston there are two wharves, one public and one priv- ate, with usable areas of 1,200 square feet and 2,400 square feet, respectively, each equipped with facilities for servicing fish- ing boats. A float landing extends some 200 feet north of the priv- ate wharf. Present facilities are congested and inadequate to ac- commodate the boats operating in the vicinity. A privately owned floating moorage, located on Joe Ney Slough, has facilities for mooring 50 fishing vessels. During the 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: Dredg- ing the channel to a depth of 30 feet between mile 4.5 and the mouth of Isthmus Slough, approximately 101 miles, with turning basins near mile 12 and mile 14 and an anchorage basin at mile 7, was initiated by continuing contract on January 4, 1950. Trash RIVERS AND HARBORS-PORTLAND, ORE., DISTRICT 2515 and hard-packed sand slowed progress during the first 2 months. A rock shelf was encountered about 2,500 feet upstream from mile 12. This rock extended upstream 300 feet, about 80 feet wide, to elevation -27 feet mean lower low water. The channel, includ- ing the turning basin, was completed from mile 15 to mile 11. A total of 2,500,000 cubic yards of material, including 3,200 cubic yards of rock, was removed. Maintenance: Dredging on the bar by the U. S. dredge Kingman and in the bay channel by the U. S. dredge Pacific resulted in ob- taining depths of 34 feet on the bar and 30 feet in the lower bay channel. A total of 825,312 cubic yards of material were removed at a cost of $106,604.85. Hydrographic surveys were made as re- quired at a cost of $8,544.26. Total costs for the fiscal year were $601,777.23, of which $486,- 628.12 was for new work and $115,149.11 for maintenance. Ex- penditures were $428,412.64. Condition at end of fiscal year.-The existing project is approxi- mately 86 percent complete. All work authorized prior to 1946 was completed in 1937. The south jetty was completed in 1928, the north jetty in 1929, and the 24-foot channel in 1937. Excava- tion of the channel to a depth of 30 feet as authorized by the River and Harbor Act of 1946 was initiated on June 6, 1948, and was completed from the entrance to mile 4.5 on February 22, 1949. Excavation of the 30-foot channel from mile 4.5 to the mouth of Isthmus Slough at mile 15 was started on January 4, 1950, and the section between mile 15 and mile 11 has been completed. The remaining work required to complete the project consists of com- pleting the 30-foot channel from mile 4.5 to mile 15 now under contract, dredging the bar to project depth of 40 feet, decreasing to 30 feet, and the construction of the Charleston Channel and small-boat mooring basin. At the close of the fiscal year the controlling depth was 34 feet on the bar, 30 feet in the entrance to mile 4.5, and 20 feet from mile 4.5 to mile 11, thence 30 feet to Isthmus Slough at mile 15. Total costs from Federal funds under the existing project have been $13,019,585.74, of which $6,893,455.03 was for new work and $6,126,130.71 for maintenance. Expenditures have been $12,- 844,364.62. In addition, $2,713.14 was expended for new work and $8,386.86 for maintenance from contributed funds. Proposed operations.-The funds unexpended June 30, 1950, in- cluding accounts receivable amounting to $435,463.61, plus antici- pated allotments of $468,800.00 for new work and $21,235.00 for maintenance, a total of $925,498.61, will be applied as follows: Accounts payable ...................................... $175,304.24 New work: Engineering .......................................... 1,925.48 Completion of excavation of the 30-foot channel between mile 4.5 and mile 15 by existing continuing contract July 1950 to March 1951 ............................ 536,783.00 Dredging entrance bar to project of 40 feet, decreasing to 30 feet, by seagoing hopper dredge, April to June 1951 165,400.00 Total new work ................................. 704,108.48 2516 REPORT OF CHIEF OF ENGINEERS, U.

COQUILLE RIVER, OREG. Location.-This river rises in the Coast Range, flows in a gen- eral westerly direction for about 100 miles, and empties into the Pacific Ocean at Bandon, Oreg., 225 miles south of the mouth of the Columbia River and 420 miles north of San Francisco Bay. (See U. S. Coast and Geodetic Survey Charts Nos. 5802 and 5971.) Previous projects.-Adopted by River and Harbor Acts of June 14, 1880, and July 13, 1892. For further details see page 1986 of the Annual Report for 1915 and page 1727 of the Annual Report for 1938. Existing project.-This provides for two rubble-mound high- tide jetties at the river mouth, the south jetty 2,700 feet long and the north 3,450 feet; and for a channel 13 feet deep at mean lower low water and of suitable width from the sea to a point 1 mile above the old Coquille River Lighthouse, and for snagging to the State highway bridge at the city of Coquille. Mean lower low water is the plane of reference. The tidal range between mean lower low RIVERS AND HARBORS--PORTLAND, ORE., DISTRICT 2517 water and mean higher high water at the mouth is 6.8 feet and the extreme range about 10 feet. The estimate of cost for new work, revised in 1945, was $316,640 exclusive of amounts expended on previous projects. The latest (1948) approved estimate for annual cost of maintenance is $41,000 for dredging and snagging. There is no approved estimate for maintenance of jetties. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents June 14, 1880 Jetties--___------------.....-------------.. ___ S. Ex.

Terminal facilities.-At Bandon there is one privately owned lumber wharf suitable for handling coastwise, vessels. There is a publicly owned wharf under construction by the Port of Bandon, which will be open to all on equal terms. At the completion of of the new wharf, it is believed facilities will be adequate for the present commerce. Operations and results during fiscal year.-Maintenance dredg- ing on the bar and in the entrance channel by the U. S. dredge Pacific during July 1949 restored project depth of 13 feet. A total of 62,834 cubic yards of material was removed at a cost of $21,2'62.93. Removal of 100 snags and 130 old piling from the channel above Bandon was accomplished by hired labor with rented equipment at a cost of $4,443.06. Hydrographic surveys were made at a cost of $4,078.91. Surveys, investigations, and plans and specifications, for repair of the south jetty and the extension of the north jetty were completed at a cost of $1,851.55. Work on these jetties was started by contract on June 26, 1950, and the work is scheduled to be completed in November 1950. Total costs for the fiscal year were $31,636.45, all for mainte- nance. Expenditures were $32,526.02. Condition at end of fiscal year.-The existing project was com- pleted in 1933. The jetties were completed in 1908 and the en- trance channel in 1933. The north jetty was reconstructed in 1942 and is in good condition. The outer 200 feet of the south jetty has subsided below ordinary low water level. The controll- ing depths are 13 feet on the bar and 12 feet from the entrance to Bandon. Total costs from Federal funds under the eixsting project have 2518 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 been $1,022,045.27, of which $316,640.21 was for new work and $705,405.06 for maintenance. Expenditures have been $1,023,327.75. In addition, $72,891.20 was expended for new work from contributed funds.

Location.-Alkali Canyon, a short tributary entering Columbia River from the south at Arlington in northern Oregon, is 145 miles east of Portland, Oreg. Existing project.--This provides for 3,000 feet of channel improvement through the town of Arlington and replacement of two culverts with bridges to provide an estimated flood capacity of 6,500 second-feet. Necessary revision of three existing street bridges is to be accomplished by local interests. The estimate of cost for new work revised in 1950 is $513,800 for construction. The cost of lands and damages is to be paid by local interests. The existing project was authorized by the Flood Control Act approved December 22, 1944 (H. Doc. 631, 77th Cong., 2d sess.). Local cooperation.-See page 8 for requirements. In addition to the usual requirements as provided by law, local interests are re- quired, except as otherwise provided, to bear the expense of all ncessary street and bridge alterations, and establish and enforce flood channel limits and regulations for protection of the flood- carrying capacity of the channel and for prevention of encroach- ment thereon. Assurances were approved April 7, 1948. Operations and results during fiscal year.-None. No costs were incurred or expenditures made. Condition at end of fiscal year.-No construction work has been done, but detailed planning for the project is essentially com- plete. The Flood Control Act approved May 17, 1950, authorized construction of the John Day Dam which, when constructed, will inundate the area proposed for improvement under this authority to the extent that construction of the project is not necessary. 2524 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Total costs and expenditures to June 30, 1950, have been $20,111.51. Proposed operations.-No work scheduled for fiscal year 1952.

COLUMBIA RIVER BASIN, LOCAL FLOOD-PROTECTION PROJECTS, PORTLAND DISTRICT Location.-The improvements included in this project are lo- cated along the Columbia River and its tributaries within the confines of the Portland, Oreg district. The major tributaries of that portion of the Columbia River in the Portland district are the John Day, Deschutes, Willamette, Lewis, and Cowlitz Rivers. Existing project.--The Flood Control Act approved May 17, 1950, approved a general comprehensive plan for the Columbia River Basin for flood control and other purposes as set forth in House Document 531, Eighty-first Congress, second session, and authorized to be appropriated the sum of $75,000,000 for the partial accomplishment of those projects. On this authorization, an amount not to exceed $15,000,000 was authorized for local flood-protection works in the Columbia River Basin, the indi- vidual projects to be selected by the Chief of Engineers with the approval of the Secretary of the Army. Local cooperation.-Section3 of the Flood Control Act approved June, 22, 1936, as amended, applies to all flood control projects. Operations and results during fiscal year.-None. There were no costs or expenditures during the fiscal year. Condition at end of fiscal year.-No work has been done under this project. There have been no costs and no expenditures. Proposed Operations.-No work is scheduled for fiscal year 1951. A sum of $100,000 can be profitably expended during fiscal year 1952 to cover costs of investigations and reports to defi- nitely establish engineering and economic feasibility at local flood protection projects. 36. AMAZON CREEK, OREG. Location.-On Amazon Creek, a tributary of Willamette River in the vicinity of and below the city of Eugene, Oreg. Existing project. This provides for channel improvement from a point above the south limits of the city of Eugene through the FLOOD CONTROL-PORTLAND, ORE., DISTRICT 2525 city to the diversion point; a diversion canal 3.5 miles in length from Amazon Creek at the diversion point to Fern Ridge Reser- voir; and an improved channel from the diversion point to Clear Lake and from Clear Lake to Long Tom River, with three lateral drainage canals, one 13,000 feet, one 15,000, and one 5,000 feet in length. The project will control the entire Amazon Creek drain- age area of 56 square miles and care for a flood of 1,000 second- feet through the city of Eugene and 1,840 second-feet at the point of diversion. The estimated cost, exclusive of local cooperation, revised in 1950 to include the additional work authorized by the Flood Con- trol Act of 1950, is $655,000. The existing project was authorized by the Flood Control Act of 1946, Senate Document 138, Seventy-ninth Congress, second session, and modified by the Flood Control Act of 1950, House Document 531, Eighty-first Congress, second session. Local cooperation.-The Flood Control Act approved July 24, 1946, provided that local interests furnish assurances safisfactory to the Secretary of War 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) hold and save the United States free from damages due to the construction works; (c) bear the cost of fences and bridge construction and revision; (d) maintain and operate all the works after completion in ac- cordance with regulations prescribed by the Secretary of War. Local interests have not completed an organization to comply with requirements.

WILLAMETTE RIVER BASIN, PORTLAND DISTRICT, OREG. 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 Clack- amas Rivers. The important tributaries that head in the Coast Range are the Luckiamute, Yamhill, and Tualatin Rivers. Minor tributaries, 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, navi- gation, and other purposes in the Willamette River Basin, as set forth in House Document No. 544 Seventy-fifth Congress, third session, and authorized $11,300,000 for the initiation and partial accomplishment of the plan recommended for initial develop- ment; the reservoirs and related works to be selected and approved by the Chief of Engineers. Subsequent flood-control acts increased the monetary authority as follows: Act of August 18, 1941, $11,000,000; act of December 2, 1944, $20,000,000; act of July 24, 1946, $35,000,000 and act of May 17, 1950, $40,000,000, a total authorization of $117,300,000. In addition, the act of May 17, 1950 contained an authorization of $75,000,000 for the Columbia River Basin, including the Willa- mette River Basin.

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 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 the Meridian site and a reregulat- ing dam 3 miles downstream at the Dexter site. Both dams will be earth and gravel fills with concrete gravity spillways and power generating facilities. The main dam will have a height of 250 feet above the stream bed and will be 3,175 feet long at the crest, forming a reservoir 14.2 miles long and providing usable storage of 456,000 acre-feet at normal pool level. The spillway, 274 feet long, will be a gate-controlled overflow type, forming the right abutment. Outlet works, consisting of slide gate controlled con- duits, will pass through the spillway section. The powerhouse will have three main generating units totaling 115,000 kilowatts ca- pacity and one station service unit of 1,000 kilowatt capacity to 2580 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 provide energy for emergency control and lighting. The reregulat- ing dam will have a maximum height of 90 feet above the foun- dation and will be 1,925 feet long at the crest, forming a pool ex- tending upstream to the main dam and providing pondage to re- regulate Lookout Point power releases to a uniform discharge. The spillway will be a gate-controlled overflow section 476 feet long forming the right abutment. Flow regulation will be accomplished by use of the spillway gates plus releases through the powerhouse, which will contain one 15,000-kilowatt unit. Lookout Point and Dexter reservoirs 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, Seventy-fifth Congress, third session. The Flood Control Acts of December 22, 1944, and July 22, 1946, modified the project to provide for recreational facilities and the Flood Control Act of May 17, 1950, House Document 531, Eighty- first Congress, second session, modified the project to provide for power generating facilities. The estimated cost of the work, revised in 1950 to include the cost of power facilities and the reregulating dam, is $38,743,000 for features other than power; $24,751,000 for power plant, includ- ing Dexter reregulating dam; and $24,736,000 for lands and dam- ages, a total of $88,230,000. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-The relocation of the Southern Pacific main line railroad and State Highway No. 58 was continued under nine separate contracts for grading and con- struction of drainage structures. Three of the contracts, totaling approximately 10.6 miles of railroad relocation, have been com- pleted, and grading and drainage structures on the remaining 12.4 miles of railroad and adjacent State Highway No. 58 were approximately 32 percent completed. A contract for fabrication and erection of superstructures for the three lower bridges was awarded and fabrication completed at Gary, Ind. Contracts were awarded for construction of the substructure for the highway underpass and the upper railroad bridge. A contract for the lower 8.14 miles of track laying and surfacing of the relocated railroad was awarded and the work 5 percent completed. A contract was awarded for construction of a Salmon hatchery, rearing ponds, roads, and water supply near Oakridge. The initial contract for construction of a portion of earth-fill section of the dam, excavation for the spillway section, river diversion channel, and clearing a portion of the borrow area was completed May 20, 1950. The main contract for construction of the earth dam, con- crete gravity spillway; and appurtenant works was awarded and notice to proceed acknowledged May 18, 1950. Mobilization of FLOOD CONTROL--PORTLAND, ORE., DISTRICT 2581 contractor's personnel and equipment and construction of the contractor's construction buildings and clearing are under way. Construction of temporary buildings, utilities and roads were completed as required. Total costs for the fiscal year were $6,835,493.54 for new work. Expenditures were $6,651,550.60. Condition at end of fiscal year.-The project is 16 percent com- plete.. Acquisition of lands for the reservoir area and railroad and highway relocations is 85 percent complete. Relocation of the Southern Pacific Railroad and State Highway No. 58 is 50 percent complete. Construction of the salmon hatchery at Oakridge is under con- tract and plans and specifications for appurtenant buildings and equipment are complete. A small portion of the earth fill section of the dam, excavation for the spillway, and construction of a river diversion channel have been completed. The main contract for construction of the dam, spillway, and appurtenant works has been awarded and erection of construction buildings and the mobilization of equip- ment and personnel are underway. Major contracts yet to be awarded for construction of the project, cover-power facilities, track laying and surfacing of ap- proximately 15 miles of railroad relocation, construction of super- structure for the upper railroad bridge, railroad buildings and signals, telephone, telegraph, and power lines, and relocation of County Road No. 360 and the Forest Ranger station. Total costs have been $13,439,017.82 for new work. Expendi- tures have been $13,025,871.46. Proposedoperations.-The funds unexpended June 30, 1950, in- cluding accounts receivable, amounting to $7,369,132.02, plus an anticipated allotment of $13,617,700 during fiscal year 1951, a total of $20,986,832.02, will be applied as follows: Accounts payable ...................................... $894,045.68 Deferred and clearing account, including preconstruction payments to main dam contractor ...................... 1,993,224.00 Engineering, including planning, explorations, design and preparation of contract plans, and specifications and de- tailed planning for Dexter reregulating reservoir ........ 879,200.00 Acquisition of lands and flowage ............ ............. 292,700.00 Construction of temporary buildings and utilities and main- tenance and operation during construction .............. 125,273.00 Construction of an addition to elementary school at Lowell, by contract awarded June 8, to be completed Sept. 15, 1950 73,212.00 Relocations: Relocate 700 feet of pole line and tenant lines along S.

COTTAGE GROVE RESERVOIR, WILLAMETTE RIVER BASIN, ORE G. 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 earth-fill dam, 1,650 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 Con- trol Act of December 22, 1944, and July 22, 1946, modified the project to provide for recreational facilities. The estimated cost (1950) for new work, is $1,844,500 for construction, and $551,500 for lands and damages, a total of $2,396,000. Local cooperation.-Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work: Con- FLOOD CONTROL-PORTLAND, ORE., DISTRICT 2585 struction of facilities for public use consisting of roads, parking areas, sewer and water systems, comfort stations, change build- ings, picnic tables, stoves, etc., progressed to 70 percent com- pletion. The construction of three water pumping plants was 20 percent completed. Selective cutting of trees and brush, general cleanup of areas, and planting of shrubs were completed in the public use areas. Maintenance: The dam and reservoir were in operation through- out the year. Normal reservoir regulation was continued. No major floods occurred and the minor flood of January 20 to 23 was com- pletely regulated below Cottage Grove Dam. The, computed peak inflow of 4,200 second-feet was reduced to 2,300 second-feet regu- lated discharge. The maximum total storage was 13,600 acre-feet, 41 percent of that available. Because of subfreezing temperatures during January and the first part of February, precipitation dur- ing this period was mostly in the form of snow. The seasonal filling of the reservoir was therefore deferred 15 days beyond the scheduled date of February 1 to conserve storage space for the anticipated snow melt run-off. Normal pool was attained on May 3, 1950. A total of 53,883 persons visited the reservoir during the year for recreational purposes. Total costs for the fiscal year were $87,896.85, of w h i c h $56,809.04 was for new work and $31,087.81 for maintenance. Expenditures were $69,136.27. Condition at end of fiscal year.-Construction of the dam and appurtenant works, initiated in August 1940, was completed in September 1942, and the dam and reservoir have been in con- tinuous operation since that date. The project as a whole has been completed except for completion of facilities for public use, which are now approximately 40 percent complete, and for construction of operator's permanent quarters. Total costs have been $2,482,602.47, of which $2,312,314.66 was for new work and $170,287.81 for maintenance. Expenditures have been $2,463,747.94. Proposed operations.-The funds unexpended June 30, 1950, including accounts receivable, amounting to $103,180.72, plus an anticipated allotment of $19,100 during fiscal year 1951 for mainte- nance, a total of $120,310.86, will be applied as follows: Accounts payable ........................................ $18,883.19 New work: Construction of domestic water supply for operator's house and warehouse by contract to be awarded .............. 3,500.00 Construction of pumping plants at Shortridge, Wilson Creek, and special events areas, by contract awarded in May and completed in September 1950 .................... 13,050.00 Construction of public use facilities at Shortridge, Wilson Creek, and special events areas, by contract awarded on April and completed in September 1950 ........... 17,300.00 Construction of operators permanent quarters, warehouse, paint shed, and utilities .............................. 50,335.34 Total new work ................................... 84,185.34 Maintenance: Operation of dam and reservoir ......................... 10,000.00 2536 REPORT OF CHIEF OF ENGINEERS, U.

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 earth-fill dam, 3,297 feet long at the crest, rising 145 feet above the stream bed, with a reservoir providing usable storage capacity at normal pool level of 70,000 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. 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 estimated cost of new work, revised in 1950, is $14,281,000 FLOOD CONTROL-PORTLAND, ORE., DISTRICT 2587 ($11,393,000 for construction and $2,888,000 for lands and dam- ages). Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-Placingof embank- ment in the earth-fill dam was carried on intensively and the dam was topped out on August 25, 1949. Approximately one million cubic yards of material was placed during the working season. The difficult job of aerating the borrow material to remove the ex- cessive water content was solved by the use of disc plows and roto-tillers. Closure of the incompleted spillway structure was accomplished on October 15, 1949. The project became officially operative on October 23, 1949, and was dedicated on that date by the Willamette Basin Commission. The reservoir, slowly filling since September 1949, reached minimum pool level, elevation 770.5 mean sea level on November 27, 1949; and the dam functioned as a flood-control structure during the winter high-water months. Filling of the reservoir for conservation purposes was initiated in February 1950, and conservation pool, elevation 832 mean sea level was reached in May 1950. Demobilization of the construction camp was completed and restoration of the temporary camp area was initiated at the end of the fiscal year. Remodeling of the existing administration build- ing for use as a service and office building was completed. A con- tract for construction of a 730-foot trash boom for the outlet structure was awarded at the end of June 1950. At the end of the fiscal year, planning and investigations were under way for proposed channel improvement and stabilization of Row River below Dorena Dam. Total costs for the fiscal year were $1,797,458.51, of which $1,777,286.41 was for new work and $20,172.10 for maintenance. Expenditures were $2,098,564.85. Condition at end of fiscal year.-The project is 92 percent com- plete. Construction of the dam and appurtenant works was com- pleted in November 1949. Remaining to complete the project is restoration of the temporary camp area, construction of operators' permanent quarters and reservoir management facilities, construc- tion of public use facilities, stabilization of Row River together with channel improvement below the dam, and providing of such other facilities that may be determined essential for the proper operation of the project. Total costs have been $12,904,721.92 ($12,884,549.82 new work funds and $20,172.10 for maintenance). Expenditures have been $12,870,220.42. Proposed operations.-The funds unexpended June 30, 1950, amounting to $343,106.68 plus an anticipated allotment of $180,- 600 for new work and $20,100 for maintenance during fiscal year 1951, a total of $543,806.68, will be applied as follows: Accounts payable ........................................ $27,340.30 New work: Engineering ..................................... 50,135.00 Land acquisition and administration .................... 5,000.00 939127-51-vol. 2-70 2538 REPORT OF CHIEF OF ENGINEERS, U.

FERN RIDGE RESERVOIR, WILLAMETTE RIVER BASIN, OREG. 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 earth-fill 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- FLOOD CONTROL-PORTLAND, ORE., DISTRICT 2539 mum height of 44 feet above the stream bed. The spillway, located near the left abutment, consists of a gravity section concrete over- flow structure controlled by six automatic radial gates. Outlet works are located in the spillway structure. The project includes rectification of the channel of Long Tom River downstream from the dam. The reservoir, having a usable storage capacity of 95,000 acre-feet, protects the Long Tom River Valley and will be operated as a unit of the coordinated reservoir system to protect the Willa- mette 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 Control Acts of December 22, 1944, and July 22, 1946, modified the project to provide for recreational facilities. The estimate of cost for new work, revised in 1950, is $3,695,065 for construction and $812,635 for lands and damages, a total of $4,507,700. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work: Con- struction of facilities for public use was continued during the fiscal year. Selective cutting of trees, cleanup, and planting of shrubs and trees in the public use area was completed. Construction of all public use facilities including roads, parking areas, boat land- ings, pier, floating dock, comfort stations, and picnic tables and stoves was essentially completed. A total of 111,473 persons visited the reservoir for recreational purposes. This was an increase of 42,773, or 62 percent over the fiscal year 1949. Construction of bank protection works along both banks of Long Tom River below the dam and clearing of the unimproved channel progressed to 59 percent completion. Planning for construction of additional stabilizers and drop structures was continued. Maintenance: The dam and reservoir were in operation through- out the year. Normal reservoir regulation was continued during the fiscal year. No major floods occurred and the minor floods and freshets which did occur were completely regulated below Fern Ridge Dam. The computed peak inflow of 8,500 second-feet oc- curred on January 22, at which time only the minimum release of 35 second-feet was made. Maximum total storage following this flood amounted to 71,260 acre-feet, or 69 percent of available storage. Two slight departures from routine regulation procedure were effected during the year; on January 29 and 30 regulated discharge was increased to 4,500 second-feet. 1,500 second-feet greater than the. normal maximum, to accelerate evacuation of ex- cess stored flood water. Because of the abnormally heavy snow cover above the reservoir, as indicated by special snow surveys, initiation of seasonal filling of the reservoir was deferred from February 1 to February 21. Total costs for the fiscal year were $238,088.97, of w h i c h $192,778.27 was for new work and $45,310.70 for maintenance. Expenditures were $187,408.27. 2540 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Condition at end of fiscal year.-The project is essentially com- plete. Construction of the dam and appurtenant work, initiated in April 1940, was completed in December 1941. Improvement of the Long Tom River channel downstream from the dam was in- itiated in July 1943 and is complete except for the construction of additional drop structures and stabilizers and completion of bank revetments. Total costs have been $4,581,596.25, of which $4,319,885.55 was for new work and $261,710.70 for maintenance. Expenditures have been $4,528,084.75.

COUGAR DAM, WILLAMETTE RIVER BASIN, OREG. Location.-On South Fork McKenzie River 4.4 miles from the mouth. South Fork McKenzie River flows northwesterly from its source and joins McKenzie River about 56.5 miles above its con- confluence with Willamette River. Existing project.-The plan of improvement provides for the construction of an earth- and gravel-filled dam about 1,630 feet long at the crest and 430 feet high above the stream bed. The dam will form a reservoir about 6 miles long with a usable capacity at normal pool of 182,000 acre-feet. The spillway, 288 feet long, will be an overflow combination chute and tunnel section located in the left abutment. The outlet tunnel and power tunnel will pass through the right abutment. The powerhouse, when authorized, will include one unit rated at 25,000 kilowatts and will be located near the toe. of the dam along the right abutment. The improve- ment will function as a unit in the coordinated system of reservoirs for multiple-purpose development of the water resources in the Willamette River Basin. The project is one of three reservoirs to replace the Quartz Creek Reservoir which was authorized by the Flood Control Act approved June 28, 1938. Authorization for Cougar Reservoir, ex- clusive of complete power features, is contained in House Re- solution 5472, approved May 22, 1950.

Location.-On Middle Fork Santiam River, 4 miles from the mouth and 56.8 miles from the mouth of Santiam River. Existing project.-The plan of improvement provides for the construction of an earth-and rock-fill dam about 1,180 feet long at the crest and 350 feet high above the stream bed. The dam will form a reservoir about 11 miles long with a usable capacity at normal pool of 322,000 acre-feet. The spillway located in the left abutment will consist of a free overflow chute section about 300 feet long at the crest. Outlet works will be incorporated in a tunnel through the, left abutment. The powerhouse, when autho- rized, will include two units rated at 40,500 kilowatts each and will be located near the toe of the dam along the left abutment. The improvement will function as a unit in the coordinated system of reservoirs for multiple-purpose development of the water re- sources in Willamette River Basin. The project is one of the three reservoirs to replace the Sweet Home Reservoir which was authorized by the Flood Control Act approved June 28, 1938. Authorization for Green Peter Reservoir, exclusive of complete power features, is contained in House Reso- lution 5472, approved May 22, 1950. The estimated cost revised in 1950, exclusive of power, is $33,573,000 for construction and $1,311,000 for lands and damages, a total of $34,884,000. Local cooperation.-Section2 of the Flood Control Act approved June 28, 1938 applies. Operationsand results during fiscal year.-None. Condition at end of fiscal year.-No work has been done. Proposed operations.-An anticipated allotment of $200,000 during fiscal year 1951 will be applied to the preparation of de- tailed plans for construction of the project. The additional sum of $100,000 can be profitably expended during the fiscal year 1952 for continuation of detailed planning for construction of the project. 44. DETROIT RESERVOIR, WILLAMETTE RIVER BASIN, OREG. Location.-On North Santiam River, with dam site 60 miles from the mouth and 45 miles southeast of Salem, Oreg. North Santiam River flows north and west for 85 miles, and unites with South Santiam River to form Santiam River, which 10 miles downstream enters the Willamette River 108 miles above its mouth. Existing project.-The plan of improvement provides for the construction of one main dam and a reregulating dam both with power generating facilities. Detroit Dam will be a concrete-gravity structure approximately 1,580 feet in length and 379 feet in height above river bed. The spillway will be a gate-controlled overflow section, and the outlet works will be gate-controlled conduits FLOOD CONTROL-PORTLAND, ORE., DISTRICT 2548 through the dam. The powerhouse with two units having a ca- pacity of 50,000 kilowatts each will be located in the right abut- ment immediately below the dam. The reservoir will have a usable storage capacity of 340,000 acre-feet. It will be operated as a unit in the coordinated reservoir system to protect the Willamette Valley from floods, to increase low-water flows in the interest of navigation and irrigation, to generate power, and for other pur- poses. The reregulating dam will be located 3 miles downstream at the Big Cliff site and will be of the concrete-gravity type, ap- proximately 128 feet in height above river-bed. The power in- stallation proposed will be one unit with a capacity of 18,000 kilowatts. The reservoir created by the dam will have a usable storage capacity of 1,800 acre-feet. The project is a unit of comprehensive plan for flood-control and other purposes in the Willamette Basin. The existing project was selected for construction under the general authorization for the Willamette River Basin contained in Flood Control Act ap- proved June 28, 1938. The Flood Control Acts of December 22, 1944, and July 24, 1946, modified the project to provide for recre- ational facilities, and the Flood Control Act of June 30, 1948, modified the, existing project to provide for the installation of hydro-electric power generating facilities, including the construc- tion of a reregulating dam. The estimated cost (1950) is $63,106,00 for construction and $6,691,000 for lands and damages, a total of $69,797,000. Local cooperation.-Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year.-Completion of the Tumble Creek and Breitenbush highway bridges completed the re- location of the North Santiam Highway except for 2.9 miles above Detroit to be constructed and financed by the Public Roads Admin- istration. The branch line railroad of the Southern Pacific Co. above Detroit Dam was abandoned and the tracks removed. Relocation of the Breitenbush River Forest Service timber access road was completed by the Public Roads Administration. Clearing of the reservoir area was continued. Diversion of the North Santiam River through the diversion tunnel was completed. A continuing contract for construction of the dam and appurtenances was awarded and work initiated March 30, 1949.

PUGET SOUND AND ITS TRIBUTARY WATERS, WASHINGTON Location.-Puget Sound is located in the western part of the State of Washington. (See U. S. 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, Sno- homish, and Snoqualmie Rivers, Wash., free from snags, debris, and drift, by means of a shallow-draft stern-wheel snag boat con- structed 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 latest (1950) approved estimate for annual cost of maintenance is $165,000. The existing project was adopted by the River and Har- bor Act of July 13, 1892 (Annual Report for 1893, p. 3425). The latest published map is in the Annual Report for 1913, page 3127. Local cooperation.-Nonerequired. 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.-Preliminarysurveys were made at a cost of $2,275.81, and maintenance dredging total- ing 127,514 cubic yards was accomplished on the Skagit River above Mount Vernon by the U. S. dredge Swinomish during the period August 12 to October 19, 1949, at a cost of $60,510.99. The U. S. snag boat W. T. Preston was operated a total of 101/2 months at a cost of $84,949.99, accomplishing the following work: RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 2573 Obstructions Dredging removed Waterway (cubic yards) ----- ----- Miscellaneous Snags Piles Skagit River, North Fork, and 49, 904 907 25 Removed 49 trees from river. river above forks.

The expendi- tures were $149,700.19. Condition at end of fiscal year.-The work has consisted chiefly of snagging and dredging in the principal tributaries of Puget Sound. 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, 1950, have been $43,336.92 for new work and $1,541,881.74 for maintenance, a total of $1,585,218.66. The total expenditures have been $1,585,- 635.23. Proposed operations.-The funds unexpended June 30, 1950. $47,954.64, together with accounts receivable, $658.18, plus an anticipated allotment of $135,000, a total of $183,612.82, will be applied to maintenance, as follows: Accounts payable June 30, 1950 ............................. $241.61 Operation of U.

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 Geo- detic 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 (a) dredging a channel known as 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: (b) for Squalicum Creek waterway, including dredging an entrance channel 200 feet wide and 26 feet deep from deep water in the bay to the main pierhead line, maintenance of the southerly half and westerly end of the Squalicum Creek basin to a depth of 26 feet at mean lower low water, and maintenance of the break- water constructed by the port of Bellingham in 1934, to a crest height of 14 feet, provided that no -dredging be done within 75 feet of wharves, piers, or similar structures. 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 estimate of cost of new work, revised in 1913, is $81,782 for Whatcom Creek waterway and $25,000 (made in 1927) for Squali- cum Creek waterway, exclusive of amount expended on previous project. The latest approved estimate for annual cost of mainte- nance is $5,000 (1950) for Whatcom Creek waterway, and $2,500 (1950) for Squalicum Creek waterway.

Local cooperation.-Fully complied with. In addition, the port . of Bellingham, since November 1945, has improved the Small- boat basin behind the Squalicum Creek breakwater constructed in 1934, by constructing breakwaters, bulkheads, floats, and utilities, and by dredging in the basin at a cost of $300,408. Further im- provements, consisting of relocation and extension of the break- water, are planned. Terminal facilities.-There are 22 wharves and piers in Belling- ham Harbor; 8 are located on Whatcom Creek waterway, 4 on Squalicum Creek waterway, and 10 on Bellingham Bay. Three wharves on Whatcom Creek waterway serve general cargo termi- nals. One of these, which is publicly owned and operated, is suit- able 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 3 wharves and the other 14 are used for various industrial purposes. These terminal facili- ties are considered adequate for existing commerce. Operations and results during fiscal year.-A condition survey of the inner portion of Whatcom Creek waterway was made in June 1950. The costs were $849.32, all for maintenance. The ex- penditures were $5,871.10. Condition at end of fiscal year.-The existing project was com- pleted in 1931. The dredging of Whatcom Creek waterway was completed in 1913. The dredging of the entrance channel in Squali- cum Creek waterway was completed in 1931, and local interests have since dredged the southerly half and westerly end of Squali cum Creek basin, and in 1934 constructed a detached rubble break water 1,500 feet long south of the basin. This structure was raised and extended in 1945 (see "Local cooperation"). In June 1950, the inner 1,300 feet of Whatcom Creek Waterway had a controlling depth of 13.3 feet except at the head of the water- way, and a depth of 25.9 feet over a width of 200 feet in the next 3,000 feet; the outer 800 feet were 26 feet deep over a 300-foot width in May 1949. In September 1947, the Squalicum Creek waterway entrance channel was 25.3 feet deep over a width of 200 feet, and the basin was 23.4 feet deep except near the edges. The costs under the existing project to June 30, 1950, have been $112,013.16 for new work and $91,028.45 for maintenance, a total of $203,041.61. The expenditures have been $203,049.76: Proposed operations.-No work is scheduled during fiscal years 1951 and 1952. 2576 REPORT OF CHIEF OF ENGINEERS, U. S.

ANACORTES HARBOR, WASH. Location.-Anacortes Harbor is on the northern point of Fidalgo 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 a channel in Cap Sante 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. 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 estimate of cost for new work, revised in 1950, is $55,350, exclusive of $24,000 contributed funds. The estimate for annual maintenance, made in 1950, is $3,000. The existing project was adopted by the River and Harbor Act of March 2, 1919 (H. Doc. 1117, 64th Cong., 1st sess.). This docu- ment contains the latest published map of the locality. Local cooperation.-Fully complied with. Terminal facilities.-There are 28 terminals in the port of Ana- cortes, including 1 on Burroughs Bay, 17 on Guemes Channel, 1 on Cap Sante waterway, and 9 on Fidalgo Bay. Three terminals on Guemes Channel are open for public use; of these, 1 is publicly owned and operated and used for handling general cargo in foreign and domestic trade; and 2, 1 publicly and 1 privately owned and operated, are used by ferries plying to the San Juan Islands. The terminal on Cap Sante 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. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The existing project was com- pleted in 1930, except that portion of Cap Sante Waterway west of R Avenue which was omitted at the request of local interests. A survey made in June 1948 shows a controlling depth of 9.4 feet in the completed portion of the waterway. The costs and expenditures from Federal funds have been $46,376.90 for new work and $7, 188.42 for maintenance, a total of $53,565.32. In addition, $23,- 188.45 has been expended from contributed funds for new work.

SWINOMISH SLOUGH, WASHINGTON 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 estimate of cost for new work, revised in 1935, was $390,- 000. The latest (1950) approved estimate for annual cost of main- tenance is $100,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents 1 July 13, 1892 Channel 4 feet deep and 100 feet wide, and dike con- H.

For latest published map, see H. Doc. 860, 63d Cong., 2d sess. Local cooperation.-Underthe provisions of the River and Har- bor 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 these conditions has not yet been 2578 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 required, as suitable areas for disposal of dredged material have been found without invoking the requirements of local coopera- tion. Terminal facilities.-There are eight wharves on Swinomish slough, all of which are privately owned and operated for indus- trial purposes and not open for general public use. These facilities are considered adequate for existing commerce. Operations and results during fiscal year.-Maintenance dredg- ing totaling 275,853 cubic yards was accomplished with the U. S. dredge Swinomish during the period October 20, 1949, to March 3, 1950. The costs were $102,386.60, all for maintenance. The ex- penditures were $102,370.28. Condition at end of fiscal year.-The existing project was com- pleted in 1937. The dikes are in good condition. In March 1950 the controlling depth at mean lower low water was 8.2 feet. The costs to June 30, 1950, have been $409,029.51 for new work and $782,256.52 for maintenance, a total of $1,191,286.03. The ex- penditures have been $1,191,283.53. Proposed operations.-The funds unexpended June 30, 1950, $75.38, together with an anticipated allotment of $4,924.62, a total of $5,000, will be applied to accounts payable, $2.50, and to a condition survey, August and September 1950.

SKAGIT RIVER, WASH. Location.-The Skagit River rises in the Cascade Mountains in British Columbia, flows in a southwesterly direction, and empties into Skagit Bay and Puget Sound through its North and South Forks and other minor distributary channels about 50 miles north of Seattle. It is about 150 miles long, of which 130 miles is in the United States. (See U. S. Coast and Geodetic Survey Chart No. 6300.) Previous projects.-The removal of snags and other obstructions in the river was undertaken in 1880 under an appropriation made by the River and Harbor Act of June 14, 1880. For further details,, see page 2006 for the Annual Report for 1915. Since 1882, this work has been continued under the general appropriation for the improvement of Puget Sound and its tributary waters. 2580 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Existing project. This provides for obtaining a reliable chan- nel of entrance through the delta by the construction of a dike at the mouth of the South Fork, regulating dikes and mattress sill near the head of North Fork, and closing subsidiary channels at the delta; and for increasing the available depth at Skagit City bar by combined dredging operations and training walls. The length of the section included in the project is 91/2 miles. The ex- treme tidal range at the mouth of the river is 20.5 feet; the range between mean lower low water and mean higher high water is 11.4 feet. The estimate of cost of new work, revised in 1950, is $217,000, including $45,000 for Skagit City bar and $172,000 for the im- provements at the mouth of the river, exclusive of amount ex- pended under previous project. The latest (1950) approved estimate for annual cost of mainte- nance is $5,000.

Local cooperation.-The River and Harbor Act of March 2, 1919, adopting the project for improvement of Skagit City bar, provided: That before the work on this project is commenced the report shall be referred to the Board of Engineers for Rivers and Harbors for review as to whether the project should be modified to meet existing conditions or whether conditions of local co-operation should be imposed. The review of this report is published in House Document 591, Sixty-sixth Congress, second session, in which the estimate for Skagit City bar is increased from $30,000 to $45,000, and in which it is recommended that no work be done until local interests as- sume responsibility for the payment of all damages claimed or alleged to result from any work that may be done under this pro- ject. No action has been taken by local interests to assume this responsibility. Terminal facilities.-There are six wharves at Mount Vernon, all privately owned and operated. One is open for public use as a general cargo terminal. These facilities are considered adequate for existing commerce. Operationsand results during fiscal year.-Studies to determine the feasibility of restoring existing structures with the view of increasing navigable depths were completed. The costs were $123.81, all for maintenance. The expenditures were $40.93. Condition at end of fiscal year.-The existing project is 46 per- cent complete. Construction of the mattress sill and closing dikes, RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 2581 and of the training dike to a length of 10,450 feet, was completed in 1911. All of the completed features are in very poor condition. The controlling elevation of the flats at the mouth of the South Fork is about 2.5 feet above mean lower low water, and the con- trolling depth at low tide depends on river stage, probably not exceeding 1 foot during periods of minimum flow. The costs and expenditures from Federal funds to June 30, 1950, have been $99,829.80 for new work and $36,257.81 for mainte- nance, a total of $136,087.61. The work remaining to be done to complete the project is to increase the depth at Skagit City bar by combined dredging operations and training walls, and extend the training dike 5,550 feet to its authorized length of 16,000 feet. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952.

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 a jetty on the easterly side of the, mouth, and a dike, with groins, on the westerly side, with a view of stabilizing the entrance, and for maintenance dredging to afford a channel 6 feet deep and of suitable width from the ocean to within the river mouth. The length of the section ins cluded in the project is: 1,500 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 estimate of cost of new work, revised in 1950, is $80,000. The latest (1950) approved estimate for annual cost of mainte- nance is $13,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents July 3, 1930 Jetty on easterly side of mouth, and a dike, with H. Doc. 125, 71st Cong., 1st sess. groins, on the westerly side, to stabilize entrance. Mar. 2, 1945 Maintenance dredging to provide a channel 6 feet H.

Recommended modifications of project.-Under date of March 8, 1950, the Chief of Engineers recommended modification of the existing project to provide a channel 10 feet deep and 100 feet wide extending 2,000 feet upstream from deep water; a basin 10 feet deep, 300 to 425 feet wide, and 2,400 feet long at the upper end of the channel; and raising the easterly jetty to a height of 15 feet above mean lower low water, all at an estimated cost to the 2590 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 United States of $375,000 for construction and annual mainte- nance of $65,750 in addition to that now required; subject to certain conditions of local cooperation, including a cash contri- bution of $20,000 toward the cost of the improvement (H. Doc. 579, 81st Cong., 2d sess.). Local cooperation.-Fully complied with, including agreement to repair any breach in the sand spit north of James Island. A channel 6 feet deep, 50 feet wide, and about 2,500 feet long, extending upstream from the Coast Guard ways, was dredged in 1948 and 1949 with Coast Guard funds. Terminal facilities.-There are four terminals at La Push; of these, three privately owned are open to public use to accommo- date 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.-Maintenance dredg- ing totaling 3,480 cubic yards was accomplished July 1 to August 15, 1949; the dike was repaired by placing 1,528 cubic yards of stone, August 31 to October 10, 1949; and a condition survey was made in April 1950, all by hired labor. The costs were $35,373.26, all for maintenance. The expenditures were $35,603.42. Condition at end of fiscal year.-The existing project was sub- stantially completed in 1931, omitting the groins, which do not appear necessary or desirable. In April 1950, the jetty showed some deterioration, the dike was in good condition, and the con- trolling depth in the entrance channel was 6 feet over a width of 120 feet. The total costs from regular funds to June 30, 1950, have been $68,000 for new work and $137,806.35 for maintenance, a total of $205,806.35. The expenditures have been $205,804.15. Proposed operations.-No work is scheduled during fiscal years 1951 and 1952.

Local cooperation.-Fullycomplied with, except as modified by the River and Harbor Act of August 30, 1935, adopting the 30- foot channel, which provides that local interests shall contribute two-thirds of the cost, but not to exceed $13,500. This condition has not been met, and local interests reported under date of April 28, 1937, that, due to heavy losses suffered by the lumber industry, they were unable to bear such a large percentage of the cost at that time. Terminal facilities.-There are two privately owned and op- erated wharves in Port Gamble Harbor; one located at a sawmill is suitable for use by oceangoing vessels, the other is used by light- draft vessels for handling petroleum products. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The existing project is 62 per- cent complete. The original project for a 28-foot channel was com- pleted in 1920. A survey made in July 1948 showed a depth of 28 feet over a width of 120 feet. The work remaining to be done to complete the project is to widen the channel to 200 feet and deepen it to 30 feet. The costs have been $11,911.08 from Federal funds and $21,- 260.09 from contributed funds for new work, and $1,666.28 for maintenance, a total of $13,577.36 from Federal funds and $21,- 260.09 from contributed funds. The total expenditures have been $34,837.45. Proposedoperations.-No work is scheduled for the fiscal years 1951 and 1952. 2592 REPORT OF CHIEF OF ENGINEERS, U. S.

Terminal facilities.-There are 90 wharves, piers, and landings on Lake Washington Ship Canal and adjacent inland waters (Shilshole Bay, Salmon Bay, Lake Union, Portage Bay, and Lake Washington). Two wharves that serve as ferry and small craft 2594 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 landings and 16 that serve for mooring and servicing vessels are open for public use; all of the former and 5 of the latter are publicly owned. Other publicly owned wharves are two used by the harbor patrol, one used by the, United States Coast Guard, one used by the Corps of Engineers, one by the United States Navy, and one by the Bureau of Fisheries. Of the remaining, 29 are used for mooring, repairing, and outfitting vessels; 13 serve for handl- ing petroleum products; 23 for various industrial purposes; and 1 is not in use. The facilities are considered adequate for existing commerce. Operationsand results during fiscal year.-The locks were oper- ated throughout the year, and ordinary repairs were made to the appurtenant structures as required. Maintenance dredging totaling 156,482 cubic yards was accomplished by the U. S. hopper dredge Pacific during the period October 16 to December 19, 1949. New switchboards were purchased and installed in the four locks oper- ating houses, new weirs were installed in the fish ladder, two initial floating mooring-bitt units were installed in the small lock and the Shilshole Bay mooring buoys were reconstructed, all by hired labor. Under contract, a boathouse was constructed at the lock site, and work was commenced on reconstruction of the north- west section of the Portage Cut revetments. The costs were $442,- 335.49, all for operations and care. The expenditures were $442,- 857.14. Condition at end of fiscal year.-The existing project was com- pleted in 1934. The water between the locks and Lake Wash- ington is nontidal and is maintained between elevations 20 feet and 22 feet above mean lower low water in Puget Sound. The controlling depths when last ascertained were as follows: From Puget Sound to the locks, 28.7 feet in July 1948; the locks to Lake Union, 30 feet in June 1948; Lake Union to Lake Washington, 28.6 feet in November 1949.

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, 19Q5; suspended by the act of June 25, 1910; and abandoned by the River and Harbor Act of August 30, 1935. For further details, 2598 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 waterway, 700 feet wide and 34 feet deep over such length as shall have been dredged by local interests to dimensions stated, was adopted by the River and Harbor Act of August 30, 1935, and superseded by the existing project for that waterway adopted March 2, 1945. For further details, see page 1702 of Annual Re- port for 1944. Existing project.-This provides for (a) City waterway, hav- ing a channel 500 feet wide and 29 feet deep at mean lower low water from deep water in Commencement Bay to the Eleventh Street Bridge, 500 feet wide and 22 feet -deep to the Fourteenth Street Bridge, and varying from 500 to 250 feet wide and 19 feet deep from the Fourteenth Street Bridge to the end of this waterway, a total length of 8,500; (b) for 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 to a turning basin of the same depth, 410 feet wide and 900 feet average length; (c) construction of two training walls, each about 700 feet long, at the mouth of Puyallup River; and (d) dredging to a depth of 30 feet, an area in the Wapato waterway (renamed Port-Industrial waterway in 1949), not near- er than 50 feet from established pierhead lines or lateral limits of the waterway, nor 100 feet from the northerly line of East Eleventh Street. The extreme tidal range is about 20 feet. The range between mean lower low water and mean higher high water is 11.8 feet. The estimate of cost for new work, revised in 1950, is $574,000, exclusive of amounts expended on previous projects, and exclusive of $40,000 to be contributed by local interests for dredging Wapato (Port-Industrial) waterway. The latest (1950) approved estimates for annual cost of mainte- nance are as follows: City waterway, $5,000; Hylebos waterway, $2,000; Wapato waterway, $1,000; Puyallup River training walls, $2,500.

Local cooperation.-Fully complied with, except for Wapato waterway, the improvement of which is subject to the provisions RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 2599 that local interests furnish, free of cost to the United States, suit- able spoil disposal areas for new work and for subsequent mainte- nance as required, and contribute $40,000 toward the initial cost. The Port of Tacoma was advised of the foregoing requirements on December 30, 1946; and in reply of December 31, 1946, stated it would provide disposal areas, but did not feel justified in con- tributing $40,000 toward the initial cost. Terminal facilities.-There are 79 wharves and piers on Tacoma Harbor. Twenty are located on Commencement Bay, 30 on City waterway, 4 on Middle waterway, 5 on Milwaukee waterway, 7 on Wapato waterway, and 10 on HIylebos waterway. Thirty of the wharves are, suitable for use by oceangoing vessels; of these, nine 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. These facilities are considered adequate for existing commerce. Operations and results during fiscal year.-A condition survey was made of Hylebos waterway above East Eleventh Street in June 1950 at a cost of $449.30. Additional costs on maintenance dredging contract completed in June 1949 were $645.35. The total costs were $1,094.65, all for maintenance. The expenditures were $25,962.28. Condition at end of fiscal year.-The existing project is 74 per- cent complete. City waterway was completed in 1905. The costs have been $150,018.58 for new work and $200,462.37 for mainte- nance, a total of $350,480.95, not including $5,000 expended for maintenance, from contributed funds. The depths available, ex- cept along the sides of the waterway, when last ascertained were as follows: 28.9 feet from Commencement Bay to South Eleventh Street, May 1949; 21.9 feet from South Eleventh Street to South Fourteenth Street, June 1949; and 16.6 feet from South Four- teenth Street to the head of the waterway, February 1949. Hylebos waterway was completed in 1939. The costs have been $212,501.60 for new work and $29,565.17 for maintenance, a total of $242,066.77. Depths available when last ascertained were as follows: 28.5 feet over a width of 200 feet from deep water in Commencement Bay to East Eleventh Street, July 1948; 27 feet over a midchannel width of 100 feet from East Eleventh Street to bend below Lincoln Avenue. and 28 feet by 100 feet above Lincoln Avenue, with a least depth in the turning basin, except near the edges, of 27 feet, June 1950. The two training walls at the mouth of Puyallup River were completed in 1934 at a cost of $51,609.12,, all for new work; and maintenance costs, all for surveys, have been $3,231.31, a total of $54,840.43. On April 4, 1943, a slide destroyed the east train- ing wall. The depth at its outer end in July 1948 was 83 feet. The west wall is in good condition. No work has been done by the Corps of Engineers on the ex- isting project for Wapato waterway. The latest survey, made in December 1944, showed a controlling depth of 30 feet over a width of about 500 feet in the lower 1,600 feet of the waterway, thence a channel 80 feet wide with a minimum depth of 14.5 feet ex- 2600 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19-50 tended southerly along the. westerly margin of the waterway' for about 1,800 feet; and a channel 200 feet wide with a minimum depth of 20.7 feet extending southerly along the easterly margin of the waterway. The easterly side of the waterway has since been improved by the United States Navy for mooring inactivated ships. The work remaining to be done to complete the project is to dredge all of Wapato waterway to a depth of 30 feet. The total costs under the existing project to June 30. 1950, have been $414,129.30 for new work, including $51,609.12 Public Works funds, and $233,258.85 for maintenance, a total of $647,388.15, not including $5,000 contributed funds for maintenance. The, ex- penditures have been $647,388.85. Proposed operations.-The funds unexpended June 30, 1950, $262.43, together with accounts receivable $0.70, and an antici- pated allotment of $43,499, a total of $43,762.13, will be applied to maintenance dredging, by contract, in Hylebos waterway, October 1950, and to condition surveys of City and Puyallup waterways.

HAMMERSLEY INLET, WASH. Location.-This inlet, connecting Puget Sound with Shelton Harbor, an arm of Oakland Bay, is located about 10 miles north- west of Olympia, Wash. (See U. S. Coast and Geodetic Survey Chart No. 6460.) Existing project.-This provides for a channel 13 feet deep at mean lower low water and 150 feet wide from the entrance of the inlet toy Shelton, a distance of about 7 miles. The extreme tidal range at Shelton is about 22.5 feet. The range between mean lower low water and mean higher water is 14.3 feet. The estimate of cost for new work, revised in 1950, is $24,500. No approved estimate for annual maintenance has been made. The existing project was adopted by the River and :Harbor Act of June 25, 1910 (H. Doc. 213, 61st Cong., 2d sess.). This docu- ment contains the latest published map of the locality. RIVERS' AND HARBORS-SEATTLE, WASH., DISTRICT 2601 Local cooperation.-None required. Terminal facilities.-There are nine terminals at Shelton, of Which four serve sawmills, one a pulp mill, three are used for handling petroleum products, and one, to which a float is attached, is used jointly for handling petroleum products and general cargo. The float is used for mooring and servicing miscellaneous small craft, and is open for public use on equal terms. These facilities are considered adequate for existing commerce. Operations and results during fiscal year.-A condition survey was accomplished during the period December 19, 1949, to Jan- uary 6, 1950. The costs and expenditures were $1,682.67, all for maintenance. Condition at end of fiscal year.-The existing project was com- pleted in 1912, except for one shoal on which the controlling depth was 10 feet. Dredging done on this shoal in May 1937 failed to in- crease, this depth on account of hardpan which the dredge was unable to remove, but the dredging on an adjacent shoal restored project depth in the remainder of the inlet. The controlling depth in the project channel in January 1950 was 6.7 feet, but a channel 10.5 feet deep over a width of 100 feet was available by deviating from the established channel. The costs and expenditures have been $9,000 for new work and $10,682.67 for maintenance, a total of $19,682.67. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952.

OLYMPIA HARBOR, WASH. Location.-This harbor is near the southern end of Puget Sound at the head of Budd Inlet, about 45 miles southwest of Tacoma. (See U. S. Coast and Geodetic Survey Chart No. 6462.) Previous projects. The original project adopted by the River and Harbor Act of July 13, 1892, provided for a channel on the east side of the harbor 250 feet wide and 12 feet deep from vicinity of Fourth Street Bridge to deep water in Budd Inlet, with a turning basin 500 feet wide at the inner end. The, River and Har- bor Act of June 25, 1910, modified and extended the project to 939127-51--vol. 2----74 2602 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 provide for a channel on the west side of the harbor 200 feet wide and 12 feet deep from deep water to a point 1,900 feet south of the west side waterway, with a turning basin at its inner end 800 feet long and a maximum width of 400 feet. For further details see page 1369 of Annual Report for 1934 and page 1873 of Annual Report for 1938. Existing project.-This provides for a channel between deep water in Budd Inlet and the port terminal, 30 feet deep at mean lower low water and 500 feet wide, with suitable additional width at the bend, and a turning basin adjacent to the port terminal 30 feet deep, 3,350 feet long, and 500 to 960 feet wide. The extreme tidal range is 22.5 feet. The range between mean lower low water and mean higher high water is 14.4 feet. The latest (1950) estimate of cost for new work, is $447,000, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $10,000.

Local cooperation.-Localinterests are required to furnish, free of cost to the United States, suitably bulkheaded areas for the re- tention of dredged materials, when and as required. The port of Olympia advised January 25, 1949, that it could not comply with the requirements at that time but would do so on the earliest possible date. Terminal facilities.-There are 17 wharves and piers on Olym- pia Harbor. Two serve general cargo terminals that are open for public use; one of these, which is publicly owned and operated, is located on the improved channel and has sufficient depths alongside to accommodate oceangoing vessels; the other, privately owned and operated, is used by vessels in the Puget Sound trade. The re- mainder are suitable for barges and scows and are used for various industrial purposes. These facilities are considered adequate for existing commerce. Operations and results during fiscal year.--A condition survey was made in July 1949. Specifications for new work and mainte- nance dredging were completed. The costs were $2,006.75 for RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 2603 maintenance, and $32.19 for new work, a total of $2,038.94. Ex- penditures were $2,096.53. Condition at end of fiscal year.-The existing project is 83 per- cent complete. The channel and basin were completed to present dimensions in 1939. In July 1949, controlling depths in the com- pleted section were as follows: 29 feet in the outer channel, 29.3 feet in the entrance channel, and 27.9 feet in the turning basin. The work remaining to be done to complete the project is to widen the entrance channel and enlarge the turning basin. The costs under the existing project to June 30, 1950, have been $262,824.98 for new work, including $105,467 Public Works funds, and $77,- 809.97 for maintenance, a total of $340,634.95.

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 har- bor 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 chan- RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 2605 nel; and improving Chehalis River from Grays Harbor to Monte- sano by dredging a channel 16 feet deep and 200 feet wide 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 dredg- ing; for maintenance of a channel 30 feet deep at mean lower low water and 350 feet wide from deep water in Grays Harbor to the Port of Grays Harbor Commission terminal, a distance of 131/4 miles; thence 26 feet deep and 200 to 350 feet wide to the Union Pacific Railroad bridge at Aberdeen, a distance of 21/4 miles; thence 18 feet deep and 200 feet wide to Cosmopolis, a distance of 3 miles; for a channel 16 feet deep at mean lower low water and 150 feet wide from Cosmopolis to Montesano, a distance of 103/4 miles, with a turning basin at Montesano of the same depth, 1,500 feet long, and 200 to 500 feet wide; for a channel 14 feet deep at mean lower low water and 100 feet wide in South Bay to Bay City; for a rubble-bound breakwater 1,000 feet long at Westhaven Cove; and for a rock-fill levee about 7,500 feet long, extending from the shore end of the south jetty northeastward along the beach at Point Chehalis. 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 (iriver flood of 1935.). The latest (1950) estimate of cost for new work, is $6,622,200. This cost does not include amounts expended on previous projects iand 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, nor does it include $211,500 to be contributed by local interests. The latest (1950) approved estimate for annual cost of maintenance dredging in the section below Aber- deen is $373,700. Local interests are to maintain the work above Aberdeen; enlarge and maintain Westhaven base. The existing project was authorized by the following river and harbor acts: 2606 REPORT OF CHIEF OF ENGINEERS, U. S.

Local cooperation.-The River and Harbor Act of July 3, 1930, adopting the 16-foot channel, provides that local interests contri- bute one-half the first cost, estimated at $211,500, and give assur- ances 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 $35,834.27 contributed, which was expended in 1931 with an equal amount of Government funds in securing a 12-foot channel to Montesano, the remaining contribution neces- sary 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 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 pipe-line 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 chan- nel 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 termi- nal 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 RIVERS AND HARBORS-SEATTLE, WASH., DISTRICT 2607 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 the improvements; enlarge and maintain the Westhaven base by dredging; and construct, in accordance with plans approved by the Secretary of the Army, maintain, and oper- ate, 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, Right-of-way required for construction and maintenance of the project was furnished by the Port Commission of the Port of Grays Harbor on May 1, 1950. Terminal facilities.-There are 29 wharves and piers on Grays Harbor and adjacent inland waters, including 1 general cargo terminal, 12 sawmill wharves, 1 pulp- and paper-mill wharf, 9 fish wharves and 6 miscellaneous industrial wharves. One general car- go wharf and two fish wharves are publicly owned and open to public use. These facilities are considered adequate for existing commerce. Operations and results during fiscal year.-New work: Hired labor operations during the fiscal year were as follows: Investiga- tions and studies were made to determine the type of construction best suited for protection of the south jetty and Point Chehalis. A current survey was completed with the cooperation of the U. S. Coast and Geodetic Survey, sand replenishment investigations were under way, and model studies were being conducted by the Waterways Experiment Station at Vicksburg. Plans and specifica- tions were completed for the Westhaven Cove breakwater and pile groins along the northeast shore of Point Chehalis, and for dredging of Bay City Channel. Costs were $77,626.76. Contract operations for dredging Bay City Channel were com- menced in May 1950 by the Port of Grays Harbor dredge Robert Gray. Removal of 30,000 cubic yards of material was accom- plished, completing 80 percent of the work at a cost of $24,266.58. A contract was awarded in May 1950 for breakwater protecting Westhaven Cove and pile groins along the northeast shore of Point Chehalis, and contractor began mobilizing equipment. Costs were $10,770.23. Maintenance: Surveys were made by the U. S. Survey boat Mamala at a cost of $25,619.28. Maintenance dredging, removal of 55,564 cubic yards of material from North Channel, was accom- plished by the U. S. hopper dredge Pacific at a cost of $26,269.56; removal of 715,870 cubic yards from Cross-Over Channel, 587,- 174 cubic yards from Sand Island Shoal, and 27,744 cubic yards 2608 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 from the Chehalis River at Aberdeen, was accomplished by, the U. S. hopper dredge Dan C. Kingman at a cost of $268,303,1; and removal of 421,853 cubic yards from the North Channel was accomplished by the leased hydraulic pipe-line dredge Robert Gray at a cost of $78,799.37. The total costs from regular funds for new work were $112,- 663.57, and for maintenance were $398,991.22. Expenditures were $478,801.71. Condition at end of fiscal year.---The existing project was 45 percent complete. 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 1936-39. In June 1949, the inner 8,956 feet of the reconstructed jetty were at grade, the next 2,800 feet showed subsidence to a maximum depth of 18 feet below grade, and the outer 900 feet had been destroyed by the sea. Serious erosion of the shore line immediately north of the jetty was occurring, the Point Chehalis beach having cut back about 1,000 feet since 1936. 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 reconstruc- ted 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 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 1949, showed that sea action had leveled the outer 325 feet; had breached the sand spit at the shore end, exposing old jetty rock to the east; and a 400-foot section about 2,000 feet from the outer end showed a settlement of approximately 4 feet. 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. The 18-foot channel below Cosmopolis and 6-foot channel between Cosmopolis and Montesano were completed in 1910, and the latter was deep- ened to 12 feet in 1931. The controlling depths, when last ascertained, were as follows: Bar channel, 31 feet over a width of 2,000 feet (May 1950) ; deep water in lower harbor to port terminal, 28.2 feet over a width of 200 feet (June 1950) ; port terminal to Union Pacific Railroad bridge at Aberdeen, 24.6 feet over a width of 200 feet (June 1950) ; Union Pacific Railroad bridge at Aberdeen to Cosmopolis, 22.6 feet over a width of 200 feet (January to March 1950); Cosmopolis to Montesano, 8.9 feet (April 1943). The work remaining to be done to complete the project is to construct breakwater at Westhaven Cove; construct groins along northeast shore of Point Chehalis; contruct works designed to prevent continued erosion of Point Chehalis and the south jetty; RIVERS AND HARBORS-SEATrLE, WASH., DISTRICT O2609 complete dredging of Bay City Channel; and increase channel depth from Cosmopolis to Montesano to 16 feet. The total costs of the existing project to June 30, 1950, have been as follows: New work Maintenance Total Regular..... $2, 954, 118. 43 $12, 240, 285. 24 -------------------------------------- $15, 194, 403.67 Public Works ------------------------------------------------- 57, 000. 00 57, 000. 00 Emergency Relief ___----------------------- ----------------- ----- 409,659. 55 409, 659. 55 Total, United States fuinds------,_ -- 2,954, 118. 43 12, 706, 944. 79 15, 661, 063. 22 Contributed funds--, -----.. -------------------------- 35, 834. 27 47, 889.45 83, 723. 72 .

WILLAPA RIVER AND HARBOR, WASH. Location.-Willapa Harbor consists of the lower reaches of Willapa River and Willapa Bay, an inlet of the Pacific Ocean lo- cated about 30 miles north of the mouth of Columbia River. Willa- pa River rises in the State of Washington, about 30 miles east of the harbor, flows in a general westerly direction, and empties into the bay. (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 Nasel 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 appropriated 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 Nasel Rivers, by snagging or otherwise. The act of March 2, 1907, con- templated 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 a channel over the bar at the mouth of Willapa Bay, 26 feet deep at mean lower low water, with a minimum width of 500 feet; for straightening the river RIVERS AND HARBORS--SEATTLE, WASH., DISTRICT 2611 channel at the Narrows about a mile downstream from Raymond by a cut-off channel 200 feet wide, 24 feet deep, and about 3,100 feet long: for a channel 24 feet deep and 200 feet wide from deep water in Willapa Bay to the forks of the river at Raymond, 24 feet deep and 150 feet wide up the South Fork as far as the deep basin above the Cram lumber mill, and up the North Fork to a point opposite Twelfth Street, with a turning basin 250 feet wide, 350 feet long, and 24 feet deep at the latter point, and a closing dike at Mailboat slough; and for a channel from deep water in Palix River to Bay Center Dock, with a depth of 10 feet at mean lower low water over a bottom width of 40 feet, widened at the shoreward end to provide a small mooring basin. The length of the section included in the project is 26 miles for the main channels, and about 2,800 feet for the Palix River-Bay Center channel. 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; and 9.2 feet at Bay Center. The extreme range is 18 feet at Toke Point; 19.3 feet at Raymond; and 16 feet at Bay Center. The estimate of cost for new work, revised in 1950, is $788,300 exclusive of amounts expended on previous projects and exclusive of $71,775 contributed by local interests. The latest (1950) ap- proved estimate for annual cost of maintenance is $277,500.

Local cooperation.-Fully complied with. Terminal facilities.-There are 34 wharves on Willapa River and Harbor, including 8 in Willapa Bay, 7 in Bay Center, 18 in Raymond and South Bend, and 1 in Tokeland. Five 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; three are located at sawmills; and one is not in use. All of the other wharves, including three that are publicly owned and operated, are used by light-draft: ves- sels in local trade. These facilities are considered adequate for ex- isting commerce. Operations and results during fiscal year.--New work: Dredg- ing of Bay Center Channel, commenced under contract in April 1949, was completed in September 1949. A total of 32,478 cubic yards was dredged during the fiscal year at a cost of $29,026.57. Maintenance: Hydrographic surveys were made by the U. S. 2612 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19 50 survey boat Mamala at a cost of $19,297.55. Maintenance dredg- ing in the amount, of 1,623,646 cubic yards was accomplished by the U. S. hopper dredge Col. P. S. Michie, including 1,245,456 cubic yards removed from the bar channel and 378,190 cubic yards from North River Shoal at a cost of $247,458.67. The: U. S. hopper dredge Pacific removed 53,178 cubic yards from the bar channel, 114,202 cubic yards from North River Shoal, and 6,500 cubic yards from Toke Point Shoal, a total of 173,880 cubic yards, at a cost of $62,894.43. Total costs were $329,650.65 for maintenance and $29,026.57 for new work, a total of $358,677.22. The expenditures were $399,- 099.94. Condition at end of fiscal year.-The existing project was com- pleted in 1936 except for the channel from Palix River to Bay Center, which was completed in 1949. The dike at the head of Mail- boat Slough is in good condition. A survey completed July 6, 1950. showed a controlling depth of 26 feet over a width ,of 350 feet across the bar. The controlling depths in the inner channel (June 1950) were as follows: Below forks at Raymond, 22.4 feet over width of 100: feet; lower 2,200 feet of North Fork, 24 feet over width of 80 feet; and lower 1,700 feet of South Fork, 19.1 feet over width of 75 feet. There has been no navigation in the upper portions of the forks, and no soundings have been taken in recent years.

ALBENI FALLS DAM, 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 939127-51-vol. 2---75 2618 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 ows 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 745 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 will con- sist of an overflow spillway in the left channel and a powerhouse having an installation of 42,600 kilowatts in the right channel, creating a reservoir with a usable storage capacity of 1,140,000 acre-feet. The dam site is 838 and 90 miles upstream from the mouths of Columbia and Pend Oreille Rivers, respectively, and is 41 miles northwesterly from Spokane, Wash.

PRIEST RAPIDS DAM, COLUMBIA RIVER, WASH. Location.-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 States near the northeast corner of the State of Washington. From the international boundary, the river flows south 112 miles to a point downstream from the mouth of Spokane River, then west 100 miles to the mouth of Okanogan River, pass- ing Grand Coulee Dam and Chief Joseph dam site en route. Swing- ing 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 boundary, to the Paci- fic Ocean. The works covered by this project are on the Columbia River at mile 397, about 28 miles east of Yakima, Wash. (See U. S. Geological Survey topographic sheet, "Priest Rapids.") Existing project.-The project provides for a combination con- crete dam and earth-fill embankment directly across the Columbia River, with a crest length of 13,500 feet at elevation 600 feet above mean sea level; for a power pool elevation of 550 feet; a flood-con- 2620 REPORT OF CHIEF OF, ENGINEERS, U.

The latest (1950) estimated Federal cost of construction of the project is $379,541,000 for 30 units and complete locks ($326,124,- 000 for 23 units and initial lock construction). Estimate for an- inual operation and maintenance (made in 1950) for 23 units is $2,- 723,000. The existing project was authorized by the Flood Control Act of May 17, 1950. (See H. Doc. 531, 81st Cong., 2d ses's., which contains the latest published map.) Local cooperation.-None required. Operations and results during fiscal year.-None -Condition at end of fiscal year.-No work has been done under this project, and there have been no costs or expenditures. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952. 29. STILLAGUAMISH RIVER, WASH. Location.-Stillaguamish River is formed by the confluence of its North and South Forks at Arlington, Wash., and flows west- erly 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 control weir 275 feet long between steel sheet pile piers at the head of Cook slough to limit flow through the slough; and 2 cut-off chan- nels, 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 estimate of cost for new work, made in 1938, is $220,000. The estimate for annual cost of maintenance, made in 1950, is $15,000. 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.-Fullycomplied with. Operations and results during fiscal year.-Repair of revet- ments was accomplished by contract during the period OctobA to ,December 1949, and a contract for aditional work was awarded in June 1950. The costs were $17,441.80, all for maintenance. The expenditures were $17,687.86. FLOOD CONTROL-SEATTLE, WASH., DISTRICT 2621 Condition at end of fiscal year.-The existing project was com- pleted in 1939. Progressive deterioration of brush mat revetments necessitates annual repair at critical points. Other features are in good condition. The costs have been $134,594.98 from regular funds and $85,999 from Emergency Relief funds, a total of '$220,- 593.98, for new work; and $68,873.70 for maintenance, a total of $289,467.68. The expenditures have been $289,453.78. Proposed operations.-The funds unexpended June 30, 1950. $11,140.20, will be applied to accounts payable, $13.90, and to: maintenance and repairing revetments, by contract, July and August 1950 and May and June 1951. The additional sum of $15,000 can be profitably expended dur- ing fiscal year 1952 for repair of revetments.

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 Gorge dam site is on the upper Green River, 6 miles southeast of Kanas- kat, 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 concrete gravity dam about 230 feet high, with spillway crest at elevation 1,205 feet above mean sea level, to create a reservoir with capacity of 106,000 acre-feet. The length along the top is 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 iof the Seattle industrial area. . The latest (1950) estimated Federal cost of construction of the project is $16,300,000, exclusive of $2,000,000 to be contributed by local interests. Estimated annual cost of maintenance and oper- ation, made in 1950, is $80,000. The existing project was authorized by the Flood Control Act 2622 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 of May 17, 1950. (See H. Doe. 271, 81st Cong., 1st sess., which contains the latest published map.) Local cooperation.-Local interests are required to contribute $2,000,000 in cash toward the cost of the project. The Washington State Legislature passed a bill, which was signed by the Governor March 1, 1949, appropriating $1,500,000 for participation in the Eagle Gorge project, contingent upon contribution by King Coun- ty, Washington, of $500,000, authorization of the project by Con- gress, and appropriation of funds therefor. The King County Board of County Commissioners, by resolution dated March 7, 1949, agreed to furnish $500,000 as their contribution. If local funds have not been transferred to the Federal Government by April 30, 1951, another Act of the Washington State Legislature will be required to re-appropriate $1,500,000 of the local contribu- tion., Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done under this project, and there have been no costs or expenditures. Proposedoperations.-No work is scheduled for fiscal year 1951. The sum of $70,000 can be profitably expended during fiscal year 1952 for advance planning. 31. 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 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 Eleventh Street Bridge and the lower end of the intercounty im- provement, 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 Eleventh 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 is de- signed to afford protection against floods about 50 percent greater than the, maximum discharge of record. The estimate of cost for new work, revised in 1950, is $4,171,- 600. The latest estimate of cost for maintenance, made in 1950, is $40,000. 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 Con- trol Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work under contract was completed on channel improvement in October 1949. Placing of additional riprap, by contract, was completed during FLOOD CONTROL-SEATTLE, WASH., DISTRICT '2623 the period January to May 1950. Acquisition of land and rights- of-way was continued by hired labor. The costs were $516,049.31. all for new work. The expenditures were $651,670.21. Condition at end of fiscal year.-The existing project was com- pleted in 1950. Reconstruction of six bridges was completed by contract, June 1947 to January 1949. Channel improvement and levee construction was accomplished by contract, February 1948 to October 1949. Placing of additional riprap was completed by contract, January to May 1950. The costs have been $3,949,335.46, all for new work. The expen- ditures have been $3,878,843.67. Proposed operations.-The funds unexpended June 30, 1950, $80,896.33, will be applied to accounts payable, $70,491.79, and to completion of real estate acquisition and establishment of sound- ing sections and profile points along the Puyallup River. The additional sum of $30,000 can be profitably expended dur- ing fiscal year 1952 for maintenance of levees and revetments.

Location.-The White River rises on the northeastern slope of Mount Rainier, in the State. of Washington, flows in a general northwesterly direction for 57 miles to its confluence with the Puyallup River. The White is the principal tributary of the Puyal- lup River and enters the Puyallup 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 rock-fill dam, 700 feet long at crest elevation and rising 425 fee.t 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 to be created will store approximately 106,000 acre-feet. Outlet works are lo- cated in the right abutment and permit controlled discharge of 16,000 cubic feet per second through two concrete-lined tunnels, with uncontrolled discharge through a spillway having a maximum 2624 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 capacity of 139,000 cubic feet per second. The improvement is de- signed to afford flood protection to the White and Puyallup River Valleys and to protect the Tacoma industrial district in conjunc- tion 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 estimated cost of new work, revised in 1950 is $13,221,100. The latest (1950) approved estimate of cost of maintenance and operation is $115,000 annually. Local cooperation.-None required. Section 2 of the Flood Con- trol Act approved June 28, 1938, applies. Operations and results during fiscal year.-New work under contract was completed on modifications to the fishway structures, installation of radiotelephone communications between the Seattle district office and the project, and the Puyallup Basin radio net- work. Work was commenced on administration and recreational facilities, access road surfacing, removal of construction trestle, and construction of access trestle to valve house stairway. New work by hired labor was accomplished on improvements to fishway structures, constructing access roads and shelters for radio-reporting network stations, and preparation of plans and specifications for future work. Operation and maintenance of the dam and appurtenances, ,gages, radio network, roads, buildings, grounds, and utilities were continued; and drift removal, fish haul, storm studies, and settle- ment surveys were accomplished. A total of 9,187 migratory fish was transported around the dam in tank trucks. There were no floods of consequence during the year. However, in February 1950, the pool rose to elevation 1,068, equivalent to a head of 173 feet and a storage of 16,752 acre-feet. Total costs for the fiscal year were $276,979.04, of which $187,- 921.46 was for new work and $89,057.58 for maintenance. Expen- ditures were -$26,233.35.

SNAKE RIVER, OREG., WASH., AND IDAHO Location.-The.Snake River, which is the largest tributary of Columbia River, rises in Yellowstone National Park, in the west- ern part of Wyoming, flows in a general westerly direction for about 1,000 miles and empties into Columbia River near Pasco, Wash., 324 miles from the Pacific Ocean. (See U. S. Geological Survey maps of Oregon, Washington and Idaho.) Previous projects.-No formal project for the improvement of Snake River was adopted by Congress prior to the act of June 13, 1902. Subsequent projects were adopted by River and Harbor Acts of June 13, 1902, June 25, 1910 and August 30, 1935. For further details see page 1991 of Annual Report for 1915, page 1849 of Annual Report for 1938 and page 2676 of Annual Report for 1948. Existing Project.-This provides for the construction of such dams as are necessary and open-channel improvement for pur- poses of providing slack water navigation and irrigation between the mouth of Snake River and Lewiston, Idaho. The pool formed by McNary Dam will provide slack water from the mouth of Snake River to mile 9.7. For maintenance purposes the project also provides for any necessary work on the River between Lewis- ton and Johnson's Bar, Idaho, as authorized under previous pro- jects. No channel dimensions are specified above Lewiston. A system of four dams between the mouth of Snake River and Lewiston has been approved. The estimated total cost, revised in 1950, including the installation of three power units at each dam is as follows: Dam 1, Ice Harbor, river mile 9.7 ......................... $95,899,000 Dam 2, Lower Monumental, river mile 44.7 ................ 86,962,000 Dam 3, Little Goose, river mile 72.2 ...................... 97,967,000 Dam 4, Lower Granite, river mile 113.1 .................... 81,977,000 Total ......................................... .... 362,805,000 The estimated annual cost of operation and care of the four locks and dams revised in 1947 is $1,940,000. The existing project was authorized by the River and Harbor Act approved March 2, 1945. (See H. Doc. 704, 75th Cong., 3d Sess.) Local cooperation.-No conditions were imposed by law. Terminal facilities.-Fromthe mouth of Snake River to Riparia, 67 miles, there are no wharves or warehouses on the river banks. From Riparia to Lewiston, Idaho, 73 miles, there are no wharves, but there are public and privately owned warehouses and grain elevators located at Penawawa, mile 91.5, Lewiston, mile 140, Asotin, mile 146 and between Asotin and 11 miles above. Just above Lewiston, mile 140.5, there is a privately owned 40 by 60 foot wharf. On the left bank between Riparia and Lewiston there are several wheat warehouses formerly used for storage of wheat to be transferred to the railroad on the right bank. Operations and results during fiscal year.-No work: Due to lack of funds, work during the year was limited to a small amount RIVERS AND HARBORS-WALLA WALLA, WASH., DISTRICT 2643 of aggregate investigation and completion of a preliminary report on powerhouse design by the architect engineer. Maintenance: Construction of a wire-bound rock jetty, 250 feet long, at Temperance Creek Rapids between Lewiston and Johnsons Bar, was accomplished by hired labor.

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 includes a dam, power plant, navigation lock, and appurtenant facilities for purposes of naviga- tion, power development, and incidental irrigation. The proposed improvement provides principally for the improvement of naviga- tion, creation of pool extending approximately 64 miles upstream to a point about 27 miles above Pasco, Wash. The dam, which will raise the normal water surface approximately 85 feet to elevation 340 mean sea level, will be approximately 7,600 feet long and will consist of an earth dam at the Oregon (south) abutment, a power- house, a spillway dam, a navigation lock, and an earth dam at the Washington (north) abutment. Suitable facilities for migrating fish, including fish ladders, will be provided. The powerhouse installation will comprise 14 units of 70,000 kilowatts each, making a total installed capacity of 980,000 kilo- watts. RIVERS AND HARBORS-WALLA WALLA, WASH., DISTRICT 2645 The spillway dam will be 1,310 feet long and will be located in the north channel of the river. The overflow crest at 291 feet above sea level will be surmounted by 22 spillway gates capable of releasing the design flood of 2,200,000 cubic feet per second. The deck will be at elevation 361 and will provide a service roadway and tracks for the operation of two gantry cranes. The navigation lock will be a single typle and will operate at all flows less than 800,000 cubic feet per second. The pool created by the spillway dam will provide a navigable channel with depths of 12 feet and over, between McNary Dam and the confluence of the Yakima River, a distance of approximately 43 miles. A controlling depth of 9 feet will be provided on Snake River from its mouth to a point approximately 10.2 miles above. All structures will be founded on a massive basalt flow that reaches a maximum thickness of 130 feet and directly overlies a sedimentary interbed.

UMATILLA HARBOR, OREGON Location. This harbor is located on the Columbia River at Umatilla Oreg., 289 miles above the mouth of the same river and 3 miles downstream from McNary Dam. Existing project.-This provides for clearing the harbor area of all shoals to a depth of 71/2 feet below low water from the chan- nel to a line which generally follows the present 7-foot depth con- tour. This line would extend downstream channelward across the shoal area above the mouth of the Umatilla River. The existing project was authorized by the Rivers and Harbors Act approved May 17, 1950 (Public Law 516, 81st Cong., 2d sess.). The estimated cost revised in 1950 is $479,000 for construction. The estimated annual cost of maintenance and operation revised in 1950 is $1,100. Local cooperation.-The River and Harbor Act approved March 2, 1945, provides that local interests furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-dis- posal areas for initial work and for subsequent maintenance as required, and hold and save the United States free from damages due to the construction works and subsequent maintenance. Local interests will repair existing terminal facilities and construct new dock and terminal facilities costing $235,000. Local interests are required to furnish assurances satisfactory to the Secretary of the Army that adequate terminal facilities open to all on equal and equitable terms would be provided. Terminal facilities.-There are no wharves, but there is a ter- minal where barges are moored close in without the benefit of a shore structure for unloading. There are three tank farms for stor- age of petroleum products and a cooperative grain elevator adja- cent to the harbor. The port of Umatilla has proposed construction of a dock and terminal facilities. RIVERS AND HARBORS-WALLA WALLA, WASH., DISTRICT 2649 Operations and results during fiscal year.---None.

NOME HARBOR, ALASKA Location.-Nome Harbor is situated at the mouth of Snake River on the northerly shore of Norton Sound, an arm of Bering Sea. It is a shallow, open roadstead, 581 nautical miles north of Dutch Harbor and 2,288 nautical miles northwest of Seattle, Wash. (See U. S. Coast and Geodetic Survey Charts Nos. 9302, 9380 and 9381.) Existing project.-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 river; and protecting all existing water-front improvements on the easterly beach by means of a rock-mound seawall 3,350 feet long extending easterly from the east jetty. The extreme tidal range is 2.8 feet and the range be- tween mean lower low water and mean higher high water is 1.6 feet, but water levels are influenced more by wind than tide. Levels of 7 feet below mean lower low water have been observed 2669 2670 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 during offshore winds, ands a level 'of 14 feet above mean lower low water has been observed: during a southerly storm. The latest (1950) approved estimate of cost for new work, is $2,400,130. The latest (1950) approved estimate for: annual cost of maintenance, exclusive of the sea wall, which is to be main- tained by local interests, is. $67,500, including $20,000i for annual maintenance&of the authorized extensions to, the jetties, but ex- cluding $2,500 to.be contributed by the city of Nome.

In accordance with the proaig nsof the River and Harbor Act of August 8, 1917, which authorized the initial improvement, the city of'Nome furnished evidence,: accepted by the Secretary of War oh December 22, 1917, that it would con- tribute $2,500 annually toward the maintenance of the improve- ment and furnish all lands or easements necessary to the proper execution of the work. These conditions have been met annually as required. In accordance with the provisions of the River and Harbor Act of June 16,: 1948, which authorized the sea wall;', ocaleinterests are required to ;furnish Without cost to the United States, the neces- sary lands, easements, rights-of-way, and quarry rights accom- plish without expenseoo the United States;, alterations asIsmy be required to utility facilities; agree to hold and save the United States free from any claims for damages that may result :from construction of the project; and agree to maintain the wOrks after completion.: Assurances of local cooperation, given 'by the city of Nome, Alaska; were approved by the Chief of Engineers August 1, 1949. The quarry rights have been secured' from the Govern- ment on land reserved by the Civil Aeronautics 'Authority. and all necessary lands, easements, and rights-of-way have' be:en 'secred atnd are on file in°the District Engineer Office, Alaska district.,' r Terminalfacilities. --Cargoes aad passeigers from ocai veelseas are lightered to and from shore a distance of about:' miles.

These' 'facilities - a onsidered od adequate for existing commerce. Operations and results during fiscal year.-Under a 3-year con- tinuing-contract, construction of the sea wall was commenced, in RIVERS AND IMAAiORS--ALASIC A DISTRICT 2671 4ofSeptember 1949; 37,866 tons of rock have been placed at a cost $316,094.95. By Government plant and hirec labor, dredging of the 400-foot extension of the basin was carried on from July through September 1949; a total of:5,350 cubic yards of material was removed at a: cost of $7 98 8 .55 . Total new work costs were $333,688.56, all from Federal funds. Maintenance was performed by Government plant and hired labor, July to October 1949 and June 1950, and consisted of dredg- ing 20,150 cubic yards at a cost of $26,480.95, and continuing revetment repairs by strengthening the tie-back system and ing with sheet steel iing, 1,250 linear feet of the south revetment ffac- at a cost of $33,612.10. Total maintenance costs were $60 093.05, including $57,593.05 from Federal funds and $2,500 from contri- buted funds. Total expenditures were $306,096.04,. all from Federalfiunds. Condition at end of fiscal year.--The project was 25 percent complete. Constructionr of the original 335- and 460-foot jetties and the revetments was commenced :in 1919 and completed ini 1923. Reconstruction of the jetties with concrete to modified lengths of 240 feet and 400 feet was completed in 1940. Dredging of the channel and the original 200- by 250-foot basin was commenced in 1919 and completed in 1922. Dredging of the 400-foot extension of the basin and construction of the sea 'wall were commenced in 1949. Timber revetments show progressive deterioration and con- crete on the east jetty has eroded to the extent that wave action passes through the jetty in one spot. Controlling depth at mean lower low water in June 1950 was 71/2 feet at the entrance bar and 8 feet in the channel and the completed portion of the basin. The work remaining to be done to complete the project is to ex- tend the jetties to their authorized lengths, complete dredging the :400-foot extension of the basin, and complete construction 9f a rock-mound sea wall approximately 3,350 feet long along the city waterfront. The costs from: Federal funds to June 30, 1950, have been $606,638.69 for new work and $1,110,266.34 for maintenance, a total of $1,716,905.03, and the expenditures have been $1,628,- 940.82. In addition, maintenance costs from contributed funds haVi been $70,000 and expenditures have been $67,500. Proposed operations.- The Federal funds unexpended June 30, 1950, $491,185.95, and contributed funds unexpended June 30, 1950, $3,000, together with accounts receivable, $2,500, and $509,- 000 anticipated to be allotted, a total of $1,005,685.95, will be applied as follows: Accounts payable June 30, 1950 .............. .......... $127,944.21 New work: Complete authorized extension of basin with U.

VALDEZ HARBOR, ALASKA Location.-Valdez Harbor is at the head of Valdez Arm, a nar- row tidal inlet extending northeastward 26 miles from Prince Wil- liam Sound in the Gulf of Alaska. It is 170 miles northeast of Se- ward, Alaska. (See U. S. Coast and Geodetic Survey Charts Nos. 8519 and 8551.) Existing project.-This provides for dredging a small-boat and seaplane basin approximately 3 acres in area and 12 feet deep at mean lower low water in the tide flat area between the wharves, and diverting a small creek away from the basin site. The range between mean lower low water and mean higher high water is 11.8 feet. The extreme range is about 22 feet. The estimate of cost for new work, made in 1937, was $68,- 500. The estimate for annual maintenance, made in 1950, is $7,000. The existing project was authorized by the River and Harbor Act approved June 20, 1938 (H. Doc. 415, 75th Cong., 2d sess.). This document contains the latest published map. Local cooperation.-Local interests are required to provide and maintain adequate floats, ramps, and mooring facilities. Only one small float has been provided, to date. Terminal facilities.-There are two privately owned wharves for deep-draft vessels, both open to general public use on payment of mooring and wharfage charges. These facilities are adequate for existing ocean-steamer commerce. Mooring facilities in the dredged basin consist of one float, inadequate for existing small- boat traffic. Operations and results during fiscal year.-A predredging sur- vey was made in October 1949. Plans and specifications for ac- complishing maintenance dredging were prepared and contract awarded in combination with other Alaska maintenance projects. The costs were $6,051.67 and expenditures $4,510.80, all for maintenance. Condition at end of fiscal year.-The existing project was com- pleted in 1939. In October 1949 the controlling depth, except along the edges of the basin, was 7.6 feet. The total cost has been 2674 REPORT OF CHIEF OF ENGINEERS, U. S.

SKAGWAY HARBOR, ALASKA Location.-Skagway Harbor is in southeastern Alaska at the mouth of Skagway River, which flows into the head of Taiya In- let (an arm of Lynn Canal) 1,100 miles northwest of Seattle, Wash., and 94 miles northwest of Juneau, Alaska. (See U. S. Coast and Geodetic Survey Charts Nos. 8202 and 8303.) Previous projects.-The original project, adopted by the River and Harbor Act of June 20, 1938, provided for a rock, brush, and earth training dike on the left bank of Skagway River, and a rubble-mound breakwater across the tide flats in prolongation of the dike. Completed in 1940, the dike and breakwater now form a part of the flood-control project for Skagway, Skagway River, Alaska, authorized by the Flood Control Act approved July 24,° 1946. For further details, see pages 2451 and 2499 of the annual report for 1946. Existing project.-This provides for dredging at the face of the wharf to a depth of 30 feet at mean lower low water for the southerly 700 feet, and to a depth of 20 feet for the next 100 feet; and for dredging a basin for small boats to a depth of 8 feet over an area of 1 acre near the north end of the wharf. The range between mean lower low water and mean higher high water is 15.7 feet. The extreme range is about 27.7 feet. The latest (1950) approved estimate of cost for new work, is $36,500. The latest approved estimate of annual cost of mainte- nance, made in 1950, is $700. The existing project was authorized by the River and Harbor Act of March 2, 1945 (H. Doc. 746, 79th Cong., 2d sess.). This document contains the latest published map. Local cooperation.-Local interests are required to give assur- ances satisfactory to the Secretary of the Army that they will hold and save the United States free from claims for damages due to construction and maintenance of the work, construct and agree to maintain a breakwater 200 feet long for protection of the basin before any dredging is done; and agree to provide and main- tain all necessary mooring floats within the basin. The town of Skagway was advised on December 30, 1946, of the requirements of local cooperation, and on January 2, 1947, indicated a willing- ness to comply. Conditions will be met before construction is ini- tiated. Terminal facilities.-There is one privately owned wharf open for public use as a passenger and general cargo terminal. Also in the harbor is one barge terminal owned by the United States Government and used in connection with military operations. These facilities are considered adequate for existing commerce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done on the existing project, and there have been no costs or expenditures therefore. Proplosed operations.-No work is scheduled during the fiscal year 1951. The sum of $36,500 is needed to be appropriated during the fis- 2678 REPORT OF CHIEF OF ENGINEERS, U. S.

JUNEAU HARBOR, ALASKA Location.-JuneauHarbor is in the portion of Gastineau Chan- nel in front Iof the city of Juneau, the capital of Alaska, at the mouth of Gold Creek. It is about 1,000 miles by water north- westerly from Seattle and 107 miles northwesterly from Peters- burg, Alaska. (See U. S. Coast and Geodetic Survey Charts Nos. 8235 ,and 8202.) Existing :project.-This provides for a small-boat basin 111/2 acres in area just north of the Douglas-Juneau bridge, with a depth of 12 feet at mean lower low water, by the construction of two rock=mound breakwaters 430 feet and 1,540 feet in length, and dredging the protected area. The range between mean lower low water and mean higher high water is 16.6 feet. The extreme range is 26.4 feet. The estimate of cost for new work, made in 1937, was $232,000. The estimate for annual maintenance, made in 1950, $3,000. The existing project was authorized by the River and Harbor Act approved August 26, 1937 (H. Doc. 249, 75th'Cong., 1st sess.) Local cooperation.-Fullycomplied with. Terminal facilities.-The terminal facilities at Juneau and Douglas, the only ports on the channel, consist of 18 wharves and floats at:Juneau, and 1 wharf at Douglas. At Juneau, one wharf municipally owned and one privately owned, both privately oper- ated, are for public use as general cargo and passenger terminals; one wharf privately owned and operated is open to the public as a cold-storage terminal; two floats are municipally owned and open for public use for the accommodation of small vessels; one wharf and one float are owned and operated by the Government; the remaining wharves are used for industrial purposes. These facilities for ocean-steamer commerce are adequate for existing and prospective needs. A number of floats are maintained for the mooring of small craft, but the available sheltered anchorages RIVERS AND HARBORS-ALASKA DISTRICT 2679 are entirely inadequate for the many small fishing and work boats frequenting the vicinity. Operations and results during fiscal year.-Under contract, operations were commenced in June 1950 for maintenance dredg- ing; 6,565 cubic yards of material were removed. The costs were $10,178.62 and expenditures $2,264.80, all for maintenance. Condition at end of fiscal year.-The existing project was com- pleted in 1939. In November 1949 the controlling depth in the basin, except along the edges, was 9.4 feet. Current maintenance dredging is 3 percent complete. The costs have been $150,715.81 for new work and $10,266.87 for maintenance, a total of $160,- 982.68. The expenditures have been $153,068.86.

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 constructing a rubble- mound breakwater 300 feet long to protect the southern portion of the 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; for an inner basin in the tide-flat area east of Shakes Island and a connecting channel from the existing moor- ing basin, all at a depth of 10 feet at mean lower low water; and for constructing a rock-mound breakwater 320 feet long on the reef north of Shakes Island. The range between mean lower low water and mean higher high water is 16.2 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. The latest (1950) approved estimate of cost for new work, is $513,000. The latest (1950) approved estimate for annual cost of maintenance is $2,000. The existing project was authorized by the following river and harbor acts: 939127-51-vol. 2--79 2682 REPORT OF CHIEF OF ENGINEERS, U. S.

Local cooperation.-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, within 12 months after completion of the basin, install suf- ficient floats and moorings to accomodate 200 small boats at one time in the dredged areas and will, when required by the Secre- tary of the Army, install facilities for an additional 200 boats in the existing basin. The necessary assurances are contained in reso- lution of the town of Wrangell, dated January 14, 1946, approved by the Secretary of War March 25, 1946. Terminal facilities.-Thereare four wharves and four floats in Wrangell Harbor. Two privately owned wharves serving general cargo and passenger terminals, one of which includes a cold- storage facility, are open for public use. The remaining wharves serve various industrial purposes. Two of the four floats are pub- licly owned and are open for public use for mooring and servicing small craft, and two privately owned floats serve oil-handling faci- lities. Additional mooring floats to accommodate 200 small boats are required. Operations and results during fiscal year.-None. Condition at end of fiscal year.,-The existing project is 32 per- cent complete. Point Shekesti breakwater was completed in 1926. The original basin was completed in 1936. In June 1948, project depths were available in the completed small-boat basin except for small areas along the edges. The work remaining to be done is to dredge the inner basin and construct the breakwater north of Shakes Island. The costs have been $91,020.98 for new wof-k and $3,349.87 for maintenance, a total of $94,370.85. The expen- ditures have been $94,370.85.

The diurnal tidal range at the mouth of the river is 16.6 feet, and the extreme range is 28.5 feet. The latest (1950) approved estimates of cost are $696,400 for new work and $10,000 annually for maintenance. The existing project was authorized by the Flood Control Act approved July 24, 1946. (See H. Doc. 695, 79th Cong., 2d sess.) This document contains the latest published map. Local cooperation.-Local agencies are required to furnish as- surances satisfactory to the Secretary of the Army that they will (a) provide without cost to the United States all necessary lands easements, rights-of-way and quarry rights; (b) hold and save the United States free from damages due to the improvements; and (c) in lieu of maintenance of the project dike and breakwater extension thereof, contribute $500 annually toward maintenance of the reconstructed and extended city dike and harbor break- water. Local interests have been advised of the foregoing require- ments. Operations and results during fiscal year.--All office studies were completed, and a draft of the definite project report and ac- companying drawings was prepared. The costs were $1,159.11, all for new work. The expenditures were $2,107.79. Condition at end of fiscal year.-No construction work has been done. Operations have consisted of completion of office studies and preparation of definite project report and accompanying draw- ings. The costs have been $20,492.54, all for new work.

Local cooperation.-Fully complied with. Terminal facilities.-At present there are 38 piers and 2 mar- ginal wharves (a 470-foot concrete wharf and a 2,600-foot timber wharf). The Federal Government owns five of the piers and the two marginal wharves. Of the remaining piers, 14 are owned by the territory of Hawaii, and 19 are privately owned. All territorial- owned piers are administered by the Territorial Board of Harbor Commissioners, and are open to shipping on equal terms. Pipe lines for Diesel oil, fuel oil, kerosene, distillate, gasoline, molasses, and water are available. In addition to these facilities, the United States Army started construction of a slip in the northerly side of Kapalama Basin ad- jacent to the storage and terminal facilities in the vicinity of the United States owned piers 39 and 40. The slip is 151 feet wide by 544 feet long on the westerly side, 468 feet long on the easterly side, and 30 feet deep, and is intended for mooring of barges and small vessels only. Work was suspended on August 22, 1945. At that time, dredging was completed, piling was driven, and 450 lineal feet of concrete curtain wall and shelf were in place. There is a definite need for a powder and explosive terminal since existing facilities do not permit the proper handling of this type of cargo. Operations and results during fiscal year.-Maintenance oper- ations accomplished with Government plant and hired labor with regular funds consisted of completion of a hydrographic survey during August 1949 at a cost of $5,723.03, and preliminary work in connection with a hydrographic survey for fiscal year 1950 at a cost of $15.78. The total cost of maintenance for the year was $5,738.81 and total expenditures were $5,923.93. Condition at end of fiscal year.-The existing project was com- pleted in August 1945. The controlling depths in August 1949 were 39 feet in the entrance channel, 35 feet in the harbor basin, 34 feet in the connecting channel and Kapalama Basin, except for lesser depths in small areas along the project line between piers 36 and 39. The total cost of the existing project to June 30, 1950, was $4,511,027.68 from regular funds, of which $3,952,363.43 was for 2700 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 new work and $558,664.25 was for maintenance. The total ex- penditures were $4,511,027.68. Proposed operations.-The balance unexpended on June 30, 1950, amounting to $7,066.60, will be applied for maintenance consisting of the completion of hydrographic survey. The additional sum of $68,000 can be profitably expended during fiscal year 1952 for the following work to be accomplished with Government plant and hired labor: Maintenance* Dredging of the harbor by Gov't.

KAWAIHAE HARBOR, T. H. Location.-This harbor is located in Kawaihae Bay, adjacent to the town of Kawaihae, and is on the northwest coast of the RIVERS AND HARBORS-HONOLULU, T. H., DISTRICT 2703 island of Hawaii, approximately 45 miles northwesterly from Hilo, island of Hawaii. (See U. S. Coast and Geodetic Survey map 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 pro- tective 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 tides 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 estimate of cost of new work made in 1949 is $5,525,500. The latest (1949) approved estimate of annual cost of mainte- nance is $10,000. 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. Local 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 (a) 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 shore line to the paved public highway; (b) hold and save the United States free from damages due to the con- struction and subsequent maintenance of the project; (c) provide and maintain at their own expense adequate public terminal and transfer facilities open to all on equal terms; and (d) accomplish without cost to the United States all necessary alterations in water supply, sewerage, drainage, and other utilities. Responsible local interests have expressed their willingness and ability to cooperate in any harbor development project that may be recommended by the Federal Government at this location. The territory of Hawaii, by authority of its legislature, would assume through the Territorial Board of Harbor Commissioners full sponsorship of the project. The territory has offered (1) to provide all lands and rights-of-way necessary for the construction of the project; (2) to construct all shore structures relative and ger- mane to the improvement of the harbor; and (3) to maintain such structures at territorial and local expense. 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 approval and development of the pro- ject 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. 2704 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Legal documents of assurances of local cooperation will be ob- tained upon availability of funds for construction of the project. Terminal facilities.--There is one pier located approximately 2,200 feet northwesterly from the location of the proposed pro- ject. It is 60 feet wide and 104 feet long, and provides 60 feet of wharf frontage and about 1,800 square feet of storage area: An approach to the pier extends 323 feet offshore and consists of a. reinforced-concrete substructure, 130 feet of timber decking, and 193 feet of reinforced-concrete slab. There is a light hoist avail- able for handling freight, and a cattle chute for handling live- stock. The pier is owned and administered by the Territorial Board of Harbor Commissioners and is open to all on equal terms. The existing facilities are, considered inadequate to permit year- round trans-Pacific and inter-island shipping, and to meet the in- creasing shipping needs of the communities of the western half of the island of Hawaii. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done under the existing project. Proposed operations.-No operations are proposed for fiscal year 1951. The sum of $50,000 can be profitably expended during fiscal year 1952 for new work consisting of the preparation of definite pro- ject report. 8. HILO HARBOR, T. H. Location.

Local cooperation.-Localcooperation required by the River and Harbor Act of October 17, 1940, was approved by the Chief of Engineers on January 23, 1941. Local interests are required to furnish suitable bulkheaded dis- posal areas for subsequent maintenance as it becomes necessary. All prior requirements have been fully complied with. Terminal facilities.-There are 23 piers and bulkhead wharves capable of docking deep-draft vessels; 16 on the north shore, 3 fronting the graving-dock turning basin, and 4 at the Army termi- nal turning basin, with an aggregate berthing length of about RIVERS AND HARBORS--PANAMA DISTRICT 2719 21,000 feet. Ten are publicly owned, 10 are United States Govern- ment property, and 3 are owned by the Government of Puerto Rico. Thirteen are open to general public use on equal terms; 21 are equipped with mechanical transfer facilities; 14 have direct connection with the railroad system. These facilities are considered adequate for existing commerce. Operationsand results during fiscal year.-Regularfunds, main- tenance: Work on a condition survey to determine available depths was completed with Government plant and hired labor at a cost of $10,545.37. Daily removal and disposal of floating debris were carried on with Government plant and hired labor at a cost of $6,880.69. Maintenance and operation of tide gage were carried on with Government plant and hired labor at a cost of $8,000. Total costs and expenditures were $25,426.06. Condition at end of fiscal year.-The existing project was com- pleted in 1942, except for 16,000 cubic yards: of rock remaining in the entrance channel that were not removed by the contractor, the contract having been terminated by supplemental agreement. The controlling depths are as follows: Entrance channel, as of September 1949, 37 feet for a width of 400 feet along the center of the channel to the bend; thence 30 feet for a width decreasing from 500 feet to 350 feet along the center of the channel from the bend to the maneuvering area; 29 feet in the maneuvering area; 29 feet in the anchorage area; 29 feet in San Antonio Channel; 29 feet in the graving dock channel and turning basin; and 25 feet in the Army terminal channel and turning basin.

MAYAGUEZ HARBOR, P. R. Location.-The harbor is on the west coast of Puerto Rico, about 110 miles by water from San Juan Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 920 and 931.) Existing project.-This provides for an approach channel to the deep-water terminal, 30 feet deep, 1,000 feet wide at the outer end, decreasing uniformly in width to 500 feet opposite the wester- ly end of the terminal, thence continuing with the same width to the inshore end of said terminal. The mean tidal range is 1.1 feet. The estimate of cost for new work, made in 1932 is $179,000. The latest estimate of annual cost of maintenance revised in 1949, is $20,000. The project was authorized by the Public Works Ad- ministration on September 6, 1933, and adopted by the River and Harbor Act of August 30, 1935 (H. Doc. 215, 72d Cong., 1st sess., and Rivers and Harbors Committee Doc. 1, 73d Cong., 1st sess.). The latest published map is in the former document. Local cooperation.-Fully complied with. Terminal facilities.-The terminals consist of two piers, used by lighters, located on shoal water in the east-central section of the harbor; and a modern deep-water terminal in the northeast section of the harbor, consisting of a bulkhead wharf about 1,270 feet long with a storage shed 800 feet long and 60 feet wide im- mediately shoreward thereof. The facilities appear adequate for the normal needs of commerce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-The existing project was com- pleted in 1934. The controlling depth in the approach channel as of December 1947 is 30 feet except for a shoal 150 feet wide with a least depth of 1.5 feet extending along the north limit for 400 feet from the inner end. In the maneuvering area, controlling depths are: 30 feet in the quarter close to the bulkhead except for a sand shoal the full width of the quarter, extending about 150 feet from the westerly end of the quarter, with a least depth of 1.5 feet and a mud shoal the full width of the quarter, extending about 400 feet from the easterly limit, with a least depth of 26 feet; 30 feet in RIVERS AND HARBORS-PANAMA DISTRICT 2721 the remaining area except for a mud shoal extending about. 200 feet from the east limit with a least depth of 26 feet. The total costs and expenditures of the existing project to the end of the fiscal year were $249,717.94, of which $21,000 of regular funds and $147,186.69 of Public Works funds, a total of $168,- 186.69 United States funds, were for new work and $81,531.25 of regular funds were for maintenance. Proposed operations.-An anticipated allotment of $41,000 dur- ing the fiscal year 1951 will be utilized for maintenance dredging with a United States hopper dredge in the entrance channel and maneuvering area. No work is scheduled for fiscal year 1952.

CHRISTIANSTED HARBOR, ST. CROIX, V. I. Location.-The harbor is on the north coast of the Island of St. Croix, V. I., about 122 miles southeast of San Juan Harbor, P. R., and about 46 miles south of St. Thomas, V. I. (See U. S. Navy Hydrographic Office Chart No. 1411 and U. S. Coast and Geodetic Survey Charts Nos. 905, 935, and 3242.) Existing project.-This provides for an approach channel 25 feet deep at mean low water and 300 feet wide from deep water in the Caribbean Sea to a turning basin of the same depth, about 600 feet wide and 900 feet long. The mean range of tide is about 1 foot. Ships using the harbor experience no inconvenience during heavy seas. The total length of the improvement is about 3,400 feet. The approved estimates of cost, made in 1947, are $261,000 for new work and $5,000 annually for maintenance. The existing project was adopted by the River and Harbor Act approved May 17, 1950 (H. Doc. 771, 80th Cong., 2d sess.). The latest published map is in the project document. Local cooperation.-TheRiver and Harbor Act of May 17, 1950, provides that local interests furnish, free of cost to the United States, suitable spoil disposal areas for the new work and subse- quent maintenance, when and as required; release the United States from all claims for damages incidental to the improvement; and that no work shall be started until local interests shall have begun the construction of the deep-water terminal, adequate to 2722 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 the needs of the port, to be built in accordance with plans approved by the Secretary of the Army and the Chief of Engineers, and shall have given satisfactory assurance that they will provide and maintain this terminal open to all on equal and reasonable terms. Terminal facilities.-These consist of a masonry bulkhead wharf about 600 feet long, owned by the municipality and open to all on equal terms, extending along the water front at the foot of King St., one of the principal thoroughfares of Christiansted. It is used by schooners, lighters, and small craft only, as the maxi- mum depth alongside is only 8 feet at mean low water. Other small privately owned landings in the harbor are used by smaller craft. The facilities are considered inadequate for the existing commerce. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done on the project. The existing entrance channel varies from 19 feet to over 100 feet in depth and from 250 to 450 feet in width, but due to its tortuous course it is difficult to navigate by vessels over 300 feet long or drawing over 15 feet. Proposed operations.-No work is scheduled for the fiscal years 1951 and 1952. 4. EXAMINATIONS, SURVEYS, AND CONTINGENCIES (GENERAL) The costs during the year were $9,698.98 for examinations and surveys, and $38,354.90 for contingencies, a total of $48,053.88. The expenditures were $48,053.88. The balance unexpended June 30, 1950, $16,146.32, will be applied during the (fiscal year 1951 to payment of expenses to be incurred under this heading.

SURVEYS FOR NAVIGATION, FLOOD CONTROL, POWER, AND IRRIGATION Existing project.-The existing project provides for making investigations of those navigable streams and their tributaries whereon power development appears feasible and practicable, with a view to the formulation of general plans for the most effec- tive improvement of such streams for the purposes of navigation and the prosecution of such improvement in combination with the most efficient development of the potential water power, the con- trol of floods and the needs of irrigation. The River and Harbor Act of January 21, 1927, adopted the project, as laid down in House Document 308, Sixty-ninth Con- gress, first session, and added the following streams to those listed in that document: Red River, Yazoo River and tributaries, Pearl River, Altamaha River and tributaries, tributaries of the War- rior, Coosa, and Tombigbee Rivers. The Flood Control Act ap- proved May 15, 1928, extended the scope of the investigation and surveys so as to include tributaries of the Mississippi River sys- tem, subject to destructive floods, and laid down certain additional investigations on these tributaries. Further study or review of reports is authorized by section 6 of the River and Harbor Act of August 30, 19"35, reading as fol- lows: That the Surveys authorized pursuant to section 1 of the River and Harbor Act of January 21, 1927, and House Document No. 308, Sixty-ninth Congress, first session, shall be supplemented by such additional study or investigation as the Chief of Engineers finds necessary to take into account important changes in economic factors as they occur, and additional stream-flow records: or other factual data. Operations and results.-Work on each of the surveys involved was inaugurated in the spring of 1928. Valuable cooperation has been received from other Federal agencies; from State, county, and municipal engineers; from levee and drainage districts, hydro- electric companies, railroads, universities, and other local sources of information. Stream-gaging stations, where needed, have been established mainly in cooperation with the United States Geo- logical Survey. At the close of the fiscal year 1950, surveys of 191 streams had been completed and reports thereon transmitted to Congress, and reports on the remaining streams well advanced to completion. For list of reports transmitted to Congress, see An- nual Report for 1938, pages: 1953-1957. In addition, four reports have been transmitted to Congress as follows: Transmitted Name of stream to Congress Printed in document No. Mississippi River above mouth of the Ohio River-..... ...

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 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 inititation of a project or modification of an existing project. The Chief of Engineers may refer to the Board for consideration and recommendation all special reports ordered by Congress and may prescribe such other duties as he desires. Additional duties were assigned to the Board under the Trans- portation Act of 1920 and it is responsible, for compiling, publish- ing and distributing useful statistics, data and information con- cerning water transportation covering over 100 coastal ports in the United States, the ports of the Great Lakes, transportation lines on the Mississippi and Ohio Rivers and the Great Lakes, and other miscellaneous publications containing information on port and terminal charges, and shipping charges at the United States ports. It compiles and publishes Part II of the Annnual Report of the Chief of Engineers which contains statistics pertaining to water-borne commerce in the United States. On June 30, 1950, the Board was composed of the following members: Brig. Gen. John S. Bragdon, Deputy Chief of Engineers, Brig. Gen. S. D. Sturgis, Jr., division engineer, Missouri River Division, Col. Orville E. Walsh, division engineer, North Pacific Division, Col. John R. Hardin, division engineer, Great Lakes Division, Col. Henry F. Hannis, resident member, Board of Engi- neers for Rivers and Harbors, Col. Bernard L. Robinson, division engineer, South Atlantic Division, and Col. Louis W. Prentiss, di- vision engineer, Southwestern Division. In addition to the foregoing, the following named officers have also been detailed for various periods during the year to member- ship on the Board: Maj. Gen. Roscoe C. Crawford, Deputy Chief of Engineers, Maj. Gen. Joseph C. Mehaffey, division engineer, Ohio River Division, Brig. Gen. George J. Nold, division engineer, 2727 2728 REPORT OF CHIEF OF ENGINEERS, U. S.

The collection and compilation of statistics on water-borne commerce have been continued by the Corps of Engineers as re- quired by law. Miscellaneous special studies were made in connection with subjects pending before the Board and in response to specific re- quests by the Office of the Chief of Engineers and other govern- mental agencies; and tables, graphs, and maps have been prepared as necessary in connection therewith. 939127-51-vol. 2--82 BEACH EROSION BOARD The Beach Erosion Board was organized under authority of section 2 of the River and Harbor Act approved July 3, 1930 (Public Law 520, 71st Cong.) which authorized and directed the Chief of Engineers under the direction of the Secretary of the Army to cause investigations and studies to be made, in coopera- tion with public agencies of the various States, to devise effective means of preventing erosion of the coastal and Great Lakes shores by waves and currents. To furnish the technical advice and assis- tance 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 investigation and submit recommendations. By executive ruling the agency applying for a cooperative study under this act is required to contribute 50 per- cent 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 particu- lar locality. A summary of such cooperative studies follows: Number of applications for studies approved prior to July 1, 1949 ... 70 Number of applications for studies approved during fiscal year 1950 .. 5 Number of reports completed prior to July 1, 1949 ................ 55 Number of reports completed during fiscal year 1950 ............ 8 Number of studies remaining to be completed (1) ................ 16 This basic law was supplemented by section 5 of the River and Harbor Act approved August 30, 1935 (Public Law 409, 74th Cong.) which 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 concern- ing 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. Another supple- mentary law was the act approved July 31, 1945 (Public Law 166, 79th Cong.), which made it the duty of the Chief of Engi- neers, through the Beach Erosion Board, in addition to partici- pating 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 determin- ing 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 shorelines 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 publicly owned property was established in the act approved 1These studies involve 30 localities and will result in 30 reports. 2731 2732 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 August 13, 1946 (Public Law 727, 79th Cong.), which declared it to be the policy of the United States to assist in the construc- tion, but not the maintenance, of works for the improvement and protection against erosion by waves and currents of the shores of the United States that are owned by States, municipalities, and other political divisions; provided, that the Federal contribution toward the; construction of protective works shall not in any case exceed one-third of the total costs and that the plan of protection shall have been specifically adopted and authorized by Congress after investigation and study by the Beach Erosion Board. 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, estuaries and bays directly connected therewith. At the end of fiscal year 1950 the Board was composed of the following members: Col. D. O. Elliott, U. S. Army, president; Col. Earl E. Gesler, United States Army, district engineer, Phila- delphia, Pa.; Col. Walter D. Luplow, United States Army, district engineer, Los Angeles, Calif.; Col. Richard W. Pearson, United States Army, district engineer, Jacksonville, Fla.; 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 Engineering, University of California; Dr. Lorenz G. Straub, engineering consultant, Division of Waterways, Depart- ment of Conservation, State of Minnesota. In addition to the foregoing, the following were also detailed for various periods during the year to membership on the Board: Mr. Richard K. Hale of Massachusetts, director, Division of Waterways, Massachusetts Department of Public Works; Col. Frederick F. Frech, district engineer, Philadelphia, Pa.; Lt. Col. William B. Stelzenmuller, assistant resident member. During the fiscal year 1950, the Board carried out studies and investigations in cooperation with appropriate agencies of various States and territories and with the field offices of the. Corps of Engineers to develop efficient works for the protection and stabili- zation of the shores and beaches of coastal and lake waters. The Board completed the review of cooperative beach erosion control reports on Atlantic City, N. J.; Presque Isle Peninsula, Erie, Pa.; Lynn-Nahant Beach, Mass.; Revere Beach, Mass.; Nantasket Beach, Mass.; Quincy Shore, Mass. ; Lake Erie shore of Lake Coun- ty, Ohio; and Lake Michigan shore of State of Illinois. The report on Atlantic City, N. J., printed as House Document No. 538, Eighty-first Congress, recommended Federal participation in the cost of protecting and improving portions of the shore within the study area. The Board also completed 1 report on preliminary ex- amination with a view to shore protection, 1 survey report on pro- tection of Federal property, and 30 reports on the beach-erosion aspects of navigation improvements as provided in section 5 of the River and Harbor Act approved August 30, 1935.

The Board has continued general investigations of means of protecting shores and beaches against erosion in accordance with the authorization contained in the act approved July 31, 1945 (Public Law 166, 79th Cong.). Publication of the quarterly bulle- tin to disseminate rapidly pertinent information to the public was continued. Four technical articles prepared by the research staff were published in the technical press. Six technical research pap- ers were published by the Board and seven papers reporting re- sults of research were in preparation. The construction of a large wave tank and a coast model test basin on a site adjacent to the Board office building was completed. Equipment of these facilities for testing is in progress. Three contracts with universities for research to supplement the staff activities were expanded and continued. At the end of the year, studies were in progress on the littoral movement of beach material; the determination of the equilibrium profiles of beaches; model scale effects in shore phenomena; the design and development of wave-measuring instruments and tech- niques, and sand samplers: the forecasting and measurement of waves on the Atlantic, Gulf, and Pacific coasts; methodst of by- passing sand at inlets; and the structural design of shore struc- tures. CALIFORNIA DEBRIS COMMISSION This Commission, consisting of three officers of the Corps of Engineers appointed by the President with the consent of the Senate, was 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, com- prising 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 Pit 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 duties prescribed by the act creating the Commission are: First: To regulate hydraulic mining in such a way as to per- mit its resumption and continuance under such restrictions as to prevent the resulting debris from being carried into navigable waters or otherwise causing damage. Second: To study and report upon general hydraulic and hy- draulic-mining conditions and matters affecting or affected by them and to make surveys, mature and adopt plans for the purpose of improving the navigability, deepening the channels, and pro- tecting the banks of the rivers, and affording 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. During the past year, the Commission consisted of the follow- ing officers of the Corps of Engineers: Col. Dwight F. Johns, president, to December 31, 1949; Col. Joseph S. Gorlinski, secre- tary, to March 31, 1950; and Col. S. N. Karrick, member, to July 31, 1949; Col. Walter D. Luplow, member, since that date. Col. John S. Seybold, South Pacific Division Engineer, and Lieut. Col. C. C. Haug, Sacramento District Engineer, have been nominated president and secretary, respectively, by President Harry S. Tru- man. The nominations must be approved by the Senate. The sec- retary has immediate supervision of the work of the Commission. IMPROVEMENTS Navigation Navigation-Continued Page Page 1.

REGULATION OF HYDRAULIC MINING AND PREPARATION OF PLANS Location.-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 provides for regulating hydraulic-min- ing operations, planning the improvement of conditions upon the Sacramento and San Joaquin Rivers and their tributaries affected by such operations, and the preparation of plans to enable hydrau- lic mining to be resumed in their drainage areas. On application by prospective miners, full investigation is made by the California Debris Commission, and permits to operate are issued to those who provide satisfactory debris-restraining basins by construc- tion of suitable dams where necessary or use Government-con- structed debris-restraining reservoirs constructed under the act of June 19, 1934, as set forth below. The latest (1950) approved estimate of cost of this work, is $15,000 per annum. The existing project was authorized by the following acts: Acts Work authorized Documents Mar. 1, 1893 Created California Debris Commission and author- Ex.

Feb. 27, 1907. Authorized California Debris Commission to permit (Amendment of sec. 13 of act api- hydraulic mining without construction of im- proved Mar. 1, 1893.) pounding works, provided there is no injury to the navigability of the above river systems or the lands adjacent thereto. June 19, 19341 Amended act of Mar, 1, 1893, which provides for con- (Amendment of secs. 18 and 23 of struction of debris dams or other restraining works act approved Mar. 1, 1893.) by the California Debris Commission and collec- tion of a 3-percent tax on the gross proceeds of each mine using such facilities, so as to eliminate this tax and substitute an annual tax per cubic yard mined, obtained by dividing the total capital cost of each dam; reservoir, and rights-of-way, by the total capacity of the reservoir for restraint of debris; and authorized revocation of Commission orders per- mitting such mining, for failure to pay this annual tax within 30 days after its due date; and also au- thorized receipt of money advances from mine owners to aid such construction, to be refunded later from the annual payments of yardage taxes on material mined. June 25, 19382 Added at the end of sec. 23 of above act, a provision (Further amendment of sec. 23 of that the Secretary of the Army is authorized to act approved Mar. 1, 1893.) enter into contracts to supply storage for water and use of outlet facilities from debris storage reservoirs for domestic and irrigation purposes and power de- velopment, upon such conditions of delivery, use and payment as he may approve; these payments are to be deposited to the credit of such reservoir project, reducing its capital cost to be repaid by tax on mining operations. 1Public, 425, 73d Cong. 2 Public, 716, 75th Cong.

RIVERS AND HARBORS--CALIFORNIA DEBRIS COMMISSION 2787 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.-There were 38 hy- draulic mining inspections made. Cost of these inspections, regula- tion of hydraulic mining, issuances of licenses and other adminis- trative work was $14,061 during the fiscal year. Total expendi- tures were $13,739.80. Administrative work overlaps that of im- provements 2, 3, and 4 hereunder and that of the Sacramento Engineer District. Condition at end of fiscal year.-The Commission has received 1,275 applications for hydraulic-mining licenses; 16 mines are licensed, of which 7 are for 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 was $722,059.60 for maintenance. The total expenditures were $721,- 652.91. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $7,826.02 will be used for payment of accounts payable, $406.69, and the remainder will be applied to maintenance as follows: Applications for permission to mine by hydraulic process will be duly investigated and considered; mines operating under exist- ing permits will be regulated, and necessary inspections, prepara- tion, and approval of plans will be made, as during preceding years. Studies, examinations, surveys, and miscellaneous opera- tions will be continued. New mines are now operating with storage afforded by the North Fork Debris Reservoir on American River, and Harry L. Englebright (Upper Narrows) Reservoir on Yuba River. The additional sum of $10,000 is needed to be appropriated for maintenance during the fiscal year 1952 in order to continue the work assigned the California Debris Commission and meet the needs of the State and general public, requiring consultation with the Commission. 2738 REPORT OF CHIEF OF ENGINEERS, U.

TREATMENT OF THE YUBA RIVER DEBRIS SITUATION- RESTRAINING BARRIERS Location.-The works are located on the Yuba River between Marysville and the place where the river emerges from the foot- hills, 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 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 estimate of cost of new work (1950) is $800,000, one-half of which was appropriated by the State of California. The latest (1950) approved estimate for an- nual cost of maintenance is $30,000, of which $15,000 is from local interests. (For details of this project in its original form see Annual Report, 1917, p. 1810, "Previous projects.") 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 River and Harbor Act of June 13, 1902 (H. Doc. 431, 56th Cong., 1st sess.). (For the latest published map, see U. S. Geologi- cal Survey topographic map of the Sacramento Valley, Calif.) Local cooperation.-Requirementsof local cooperation are being complied with, progressively with the work. The State of Cali- fornia contributes annually an amount equal to Federal allotment. Operations and results during fiscal year.-Maintenance: Con- struction of new current retards and repair of current retards near Marysville by contract and channel clearing by removal of snags and repair of current retards between Marysville and Daguerre Point, 11 miles upstream, by hired labor were accom- plished at a total cost of $40,603, of which $16,465.79 was United States funds, and $24,137.21 was contributed funds. The expendi- tures were $16,465.79 from United States funds and $24,137.21 from Contributed funds, a total of $40,603. RIVERS AND HARBORS-CALIFORNIA DEBRIS COMMISSION 2789 Condition at end of fiscal year.-The existing project was com- pleted in 1935. Three training walls, having a total length of 85,- 100 feet and providing two 500-foot wide channels, have been built, partly by gold-dredging companies 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 has been cleared of obstructions. Dikes have been built to block off old sand channels. The result has been to hold millions of cubic yards of mining debris in Yuba River which would otherwise have passed into the navigable channels of Feather and Sacramento Rivers. The Yuba Consolidated Gold Field Co., under Department of the Army permit of 1944, is dredging a large channel 600 feet wide which will replace the two existing 500-foot channels above the dam. This channel at a point about 3,000 feet upstream of the dam will be about 1,000 feet north of the present north channel, and it will be constructed to give almost a 90 ° approach for flows toward the crest of the dam. Dredging operations are now under- way on the upstream right bank, at the new north training wall. The total cost was as follows: Funds New work Maintenance Total United States-.................. . ._... ___. $361, 482. 28 $305, 873. 53 $667, 355. 81 Contributed-... _ _..- .. __------------------- ------ - 361, 776. 74 299, 360. 47 661, 137. 21 Total ...... . . .. 723, 259. 02 605, 234. 00 1, 328, 493. 02 The expenditures were $667,355.81 from United States funds, and $661,137.21 from contributed funds, a total of $1,328,493.02.

SACRAMENTO RIVER AND TRIBUTARIES, 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 num- ber.) Existing project.-The project was designed to permit the re- sumption of hydraulic mining on a substantial scale and provides for the construction of four reservoirs at the following sites: (1) The Upper Narrows (Harry L. Englebright) on Yuba River; (2) the North Fork site on the North Fork of American River; (3) a site on the Middle Fork of American River; and (4) a site on Bear River. The latest (1950) approved estimated Federal costs for new work and for annual maintenance are $6,945,000 and $25,000, respectively. 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 docu- ment. 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.-Satisfactoryassurances were to be furnished the Secretary of the Army for repayment of the capital cost of the reservoirs from taxes on material hydraulically mined, under licenses, and impounded in these reservoirs. These have been furn- ished and accepted for sites (1), (2), and (3) above. Operations and results during fiscal year.-New work: There were no operations nor expenditures. Maintenance: Operations during the fiscal year included miscel- laneous repairs at the North Fork and Harry L. Englebright Dams, repair of access roads at North Fork Dam, repair of guard rails at Harry L. Englebright Dam, and guard service for each dam. The preceding work was by hired labor; total cost for $16,- 009.79. Total expenditures were $15,386.44. RIVERS AND HARBORS-CALIFORNIA DEBRIS COMMISSION 2741 Condition at end of fiscal year.-The existing project is 76 per- cent complete. The North Fork Dam and Reservoir was completed and in use at the end of the fiscal year 1939; additional work of excavation and reinforcement at the left abutment of the dam was done in the fiscal year 1941. The dam is 155 feet high, 620 feet long, and the reservoir has a debris-storage capacity of 26,- 000,000 cubic yards. The Harry L. Englebright Dam was com- pleted in January 1941; the reservoir has been in use for storage of hydraulic-mining debris. Minor finishing work was completed under supplementary agreement; repairs to footings and abut- ments and improvements of grounds were completed in 1944. The dam is 260 feet high, 1,142 feet long, and the reservoir has a debris-storage capacity of 118,000,000 cubic yards. Work at the Ruck-A-Chucky dam site on the Middle Fork of American River was stopped, settlement of the contract was completed, and field investigations were made and report rendered with a view to the selection of another site. Work was postponed on the Dog Bar site on Bear River due to litigation involving mining interests, and a review of the report in the project document was made, giving con- sideration to alternative locations of the proposed dam. This re- view has been reassigned. The total cost of all activities was $5,291,374.99 for new work and $278,984.38 for maintenance, a total of $5,570,359.37. The total expenditures were $5,569,432.55. Proposedoperations.-The balance unexpended at the end of the fiscal year, provided by an appropriation from Hydraulic Mining in California, Debris Funds, in May 1950, amounting to $49,- 087.41, less an anticipated revocation of $21,311, a total of $27,- 776.41, will be applied as follows: Accounts payable ........................................... $926.82 Maintenance (by hired labor and contract): Repairs to access roads to North Fork and Harry L. Engle- bright Debris Reservoirs and repairs and replacements at the two dams, Aug. 1, 1950 to June 30, 1951 .......... 9,000.00 Cost of watchmen's services at North Fork and Harry L.

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 Shasta Dam. Previous projects.-The original project was adopted by the River and Harbor Act of June 25, 1910, and was formerly reported under the title "Alleviation of Debris Conditions in the Sacra- mento and Feather Rivers." For further details see Annual Report for 1917, page 1815, and Annual Report for 1938, page 1995. Existing project.-This plan of improvement provides protec- tion for the agricultural and urban areas of the Sacramento Valley by the enlargement and rectification of existing channels; the con- struction of levees along existing waterways; the construction of leveed auxiliary bypass channels, together with the construction of four bypass weirs and the reconstruction of another, and con- struction of outfall gates at the mouth of Butte Slough, to relieve the natural waterways of flows beyond their capacity; the con- struction of intercepting channels, levees, pumping plants and drainage works to convey intercepted and interior drainage into the project waterways; the stabilization of caving banks by the construction of bank protection works and levee set-backs; the clearing of bypass and natural flood channels to provide efficient flow characteristics and abridge low water channel meanders; and the construction of upstream storage reservoirs. From the mouth of Sacramento River at Collinsville upstream to the mouth of Cache Slough (mile 14.3), the principal work is enlargement of the channel of the Sacramento River as required to carry the entire flood discharge of the river basin. Between the mouth of Cache Slough and Chico Landing on the Sacramento River (mile 193.1), and including all tributaries en- tering the main stream below this point, the principal works are leveed natural waterways in conjunction with weirs, outfall gates and leveed bypasses to carry surplus flows. From Chico Landing upstream to Red Bluff (mile 245.5), and on the lower portions of tributaries in this reach, the work consists of channel clearing, rectification, snagging and bank protection. Upstream storage RIVERS AND HARBORS-CALIFORNIA DEBRIS COMMISSION 2743 reservoirs to regulate flows in the Sacramento River are provided at Black Butte Dam and Reservoir, westerly from Orland, Glenn County, on Stony Creek, a tributary entering the Sacramento River at mile 190; and at Table Mountain (Iron Canyon) Dam and Reservoir, a low-level dam and reservoir with power facili- ties, northerly of Red Bluff on the Sacramento River, in Tehama and Shasta Counties. In addition, local improvements, chiefly levees, are provided on nine minor tributaries of the Sacramento River, and maintenance pending completion of all works other than storage reservoirs is provided for the enlarged channel below the mouth of Cache Slough, including revetment of the banks of the cut. Construction of the necessary works of improvement for the protection of Upper Butte Basin is also provided for. The improvements enumerated above which were included in the Flood Control Act of December 22, 1944, namely: construc- tion and enlargement of levees along the Sacramento and Feather Rivers, in Butte Basin and in Sutter and Yolo Bypasses; for local improvements, chiefly levees, on nine minor tributaries of the Sac- ramento River; and for construction of the Black Butte and Table Mountain (Iron Canyon) Reservoirs; and for construction of the necessary works of improvement in the Flood Control Act of May 17, 1950, for the protection of the Upper Butte Basin, are re- ported under "Sacramento River and Tributaries, California, from Collinsville to Shasta Dam" by the Sacramento District, in the Annual Report for the Sacramento District, page 2432. The estimated (1950) Federal cost of the 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 $55,635,000, exclusive of amounts expended under the previous project. In addition, local interests have contributed for project work a total of $4,949,437.55 for levee construction, bank-protec- tion works, and levee setbacks. The existing project was adopted by the Flood Control Act of March 1, 1917 (H. Doc. 81, 62d Congress, 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.). Local cooperation.-The Flood Control Act of May 15, 1928, provided that local interests were to contribute one-half the cost of construction of project levees, estimated at $3,191,500, and furn- ish the lands, rights-of-way, and easements therefor. The modified project which was adopted in the River and Har- bor 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 im- pede the flood run-off, unless approved by the California Debris Commission; should hold and save the United States free from 2744 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 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 docu- ment (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 with- out cost to the United States all lands, easements, and rights-of- way for said works, including the cost of all alterations to high- ways, 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 under- standing that the contribution of funds will be made as required by the progress of the work; and the State of California was to under- take the operation of the movable top of Sacramento Weir in ac- cordance with the schedules established by the California Debris Commission. The modification of the project authorized in the Flood Con- trol Act of August 18, 1941, relieves, local interests of all future construction costs under the. existing project, but requires them to give assurances satisfactory to the Secretary of the Army that they will provide (a) all needed lands, easements, and rights-of- way free of cost to the United States, (b) bear the expense of necessary highway, railroad, and bridge alterations, (c) hold and save the United States free from claims for damages resulting from construction of the works, and (d) maintain and operate all flood-control works after completion, in accordance with regula- tions prescribed by the Secretary of the Army. The requirements are being complied with as needed.

ANNUAL REPORT OF THE PRESIDENT, MISSISSIPPI RIVER COMMISSION, FOR THE FISCAL YEAR ENDING JUNE 30, 1950 Commission headquarters:-Mississippi River Commission Building, Vicksburg, Miss., P. O. Box 80. Commissioners. The commissioners during the fiscal year were Brig. Gen. P. A. Feringa, Corps of Engineers, president; Edward Flad, civil engineer, to June 30, 1950; Col. Ernest Graves, Corps of Engineers, retired; Rear Adm. Leo O. Colbert, director, United States Coast and Geodetic Survey, retired; Albert L. Culbertson; Col. Clark Kittrell, Corps of Engineers, to February 20, 1950; DeWitt L. Pyburn, civil engineer; and Brig. Gen. Don G. Shingler, Corps of Engineers, since April 25, 1950. Jurisdiction.-The Mississippi River Commission, created by act of Congress approved June 28, 1879, is charged, under the direction 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 interest of navigation between Cairo, Ill. (mile 966), and Baton Rouge, La. (mile 230). It also is charged with prose- cution 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) ; more specifi- cally charged with control of headwater floods of the St. Francis and Yazoo Basins including L'Anguille River and Yazoo tribu- taries, respectively; protection of portions of the backwater areas near the mouths of the White, the Yazoo, and the Red Rivers, and with improvements of Bayous Rapides, Boeuf, and Cocodrie. La., Boeuf and Tensas Rivers, Bayou Macon and Bayou Lafourche, La., and Ark., and West Tennessee tributaries. Backwater limits on tributary streams are considered to be located where backwater curves from the maximum Mississippi River flood intersects maxi- mum flood flow lines of tributaries. Location and description.-The Mississippi River rises in Lake Itasca, Minn., flows in a general southerly direction for 2,350 miles, and empties into the Gulf of Mexico. Its drainage area, about 1,245,000 square miles, embraces all or part of 31 States between the Rocky and Appalachian Mountains and parts of 2 Canadian Provinces. Its alluvial valley, some 30,000 square miles in extent, includes former overflow areas designated as the St., Francis, White, Tensas, Atchafalaya, and Lafourche Basins west of the river and the Yazoo and Pontchartrain Basins east of the river. Observations made by the Mississippi River Commission to June 30, 1949, show approximate maximum and minimum dis- 2751 2752 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 charges between 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 Missis- sippi 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 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; 53 feet at Memphis; 57 feet at Red River Landing; and 23 feet at Carrollton. The river is nontidal above the mouth of Red River where the amplitude of the tide rarely exceeds 0.1 foot during extreme low water. ORGANIZATION Office of the president.-The President of the Mississippi River Commission is its executive officer. Two officers have been detailed for duty in the office of the President of the Commission-as Sec- retary of the Commission and deputy president. Field operations of the Commission below Cape Girardeau are conducted by three engineer districts with limits as follows: New Orleans district.-MississippiRiver, Head of Passes (mile 0) to vicinity of Black Hawk, La.

Lt. Col. Ralph D. King, Corps of Engineers, director. By General Order No. 9, dated July 29, 1949, issued by the Chief of Engineers, Department of the Army, the Waterways Experi- ment Station was removed from the jurisdiction of the President, Mississippi River Commission, and placed under the direct juris- diction of the Chief of Engineers, effective August 10, 1949. 2754 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 PREVIOUS PROJECTS The project outlined in a report by the Commission dated February 17, 1880, contemplated improvement of the channel to secure a least depth of 10 feet at extreme low-water by contrac- tion of the low-water channel, protection of banks against caving, and control of flood-water by levees. For further details see page 1944, Annual Report for 1932, and page 1682, Annual Report for 1937. EXISTING PROJECT This provides for protection of the alluvial valley of the Mis- sissippi, Head of Passes to Cape Girardeau, from floods by means of levees, floodwalls, floodways, reservoirs (in the St. Francis and Yazoo Basins), bank stabilization and channel improvements in and along the river and its tributaries and outlets insofar as affected by backwater of the Mississippi River and for levee work between Cape Girardeau and Rock Island. The project also pro- vides for bank protection, channel improvement, contraction works and dredging to secure a navigable channel 12 feet deep and 300 feet wide from Baton Rouge to Cairo. Improvements completed under previous project and incorporated in the project are main- tained in accordance therewith. The total authorized cost, includ- ing the modifications authorized by the act of May 17, 1950, is $1,292,748,500, including maintenance charges through August 18, 1941. The estimated cost of annual maintenance is $15,000,000. Table A lists major Mississippi River improvements included in the existing project; table B lists those on tributaries and out- lets; and table C contains data pertinent to dams and reservoirs.

OPERATIONS AND RESULTS DURING FISCAL YEAR Commission activities.-The two hundred thirty-fourth and two hundred thirty-fifth sessions of the Commission were held on board the U. S. steamer Mississippi en route from Cairo, Ill., to New Orleans, La., September 25 to October 1, 1949, and April 28 to May 5, 1950, respectively. 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, MISSISSIPPI RIVER COMMISSION 2761 commercial, and other interests presented problems pertaining to flood control and navigation. At the two hundred thirty-fifth ses- sion an inspection trip was made through the Atchafalaya River Basin to Morgan City, La., thence to New Orleans, La., via the Intracoastal Waterway. An emergency high water inspection was made February 15 to 18, 1950, on the steamer Mississippi from Cairo to Memphis, at which time the New Madrid floodway was inspected. In addition to the inspection trips via steamer, members of the Commission inspected major flood-control and navigation im- provements under the jurisdiction of the Commission and reviewed and acted on a report, on White River with respect to Des Arc and vicinity, Ark., which has since been authorized by Public Law 516, Eighty-first Congress, second session. The president, Mississippi River Commission, and his. engi- neering assistants made periodic inspections of flood-control, navi- gation, and related works under the existing project along the Mississippi River and tributaries in the alluvial valley from Cairo to the Gulf of Mexico. During the period of high water, January- May, 1950, flood-fighting forces were mobilized. Through the com- bined efforts of local authorities and departmental personnel, close contact with the flood situation was maintained and operations were carried out efficiently. Surveys, gages, and observations.-(See p. 1961, Annual Report for 1932.) Routine hydrographic surveys of the river between Head of Passes and Cairo, construction and special surveys and inspections were made as required. Gages were maintained and discharge observations made. Results thereof are presented in detail in annual pamphlets issued by the Mississippi River Com- mission. Alluvial valley mapping.-Preparationand publication of con- toured maps of the valley (scale 1 : 62,500) were continued. Dur- ing the fiscal year work in the Memphis district was continued on new authorized quadrangles east of Memphis, Tenn., two of which were completed-Moscow and Mason; eight new and remapped quadrangles are in the process of reproduction-Hales Point, Rialto, Osceola, Moscow, Colliersville, Jericho, Modoc, and Mell- wood; and specifications were prepared for mapping of three quad- rangles, in West Tennessee, by contract. Six additional quad- rangles are about 95 percent complete, and preparation has been started on the compilation of ten others. In the Vicksburg district new Byhalia and Tyro (formerly Chulahoma) quadrangle maps were published, and Potts Camp (formerly Waterford) and a re- vised Milestone quadrangle map were forwarded for publication. In the New Orleans district, compilation was continued on the five remaining quadrangle maps of the nine new maps in the vicinity of New Orleans and south to the Gulf of Mexico, of which four manuscripts (scale 1 : 48,000) -East Delta, West Delta, Breton Sound, and New Orleans-were completed. Major revisions were made to the Opelousas, Palmetto, Bayou Sale, and Spanish Fort quadrangle maps. 939127-51-vol. 2- 84 2762 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Costs incurred for surveys, gages, and observations and for alluvial valley mapping during the fiscal year, not including cost of surveys incident and chargeable to construction features, are given in table F. Dredging.-A total of 38,898,641 cubic yards of material was dredged in the Mississippi River channel by districts as follows: New Orleans district--Channel maintenance.-Channel patrol and surveys of river crossings were made as required. One Govern- ment pump barge operated on the Mississippi River at mile 371 moving 432,294 cubic yards. On September 1,1949, maintenance of the project navigation channel between mile 320 and mile 424 be- came a function of the Vicksburg district. Vicksburg district- (a) Channel maintenance.-Three Govern- ment-owned pump barges and two leased dredges were operated at 10 locations on the Mississippi River between mile 320 AHP and mile 593 AHP, moving 9,223,5741 cubic yards of material.

MISSISSIPPI RIVER COMMISSION 2763 the New Orleans, Texas & Mexico Railway Co. Clearing was com- pleted under a separate contract in November 1949. Construction of the embankment section commenced July 18, 1949, and is 64 percent complete. The Texas & Pacific Railway Co. completed con- struction of the Ville Platte-Opelousas railway connection and re- habilitation of the Ville Platte-Bunkie line in February 1950, to permit detour of trains to the high-level crossing. Necessary re- arrangement of utilities over the floodway was continued. Bayou Sorrell lock was completed June 6, 1950, except for con- struction of guide walls and tender's house and office. The lock is constructed of reinforced concrete on timber pile foundation, with an earth chamber 600 feet long providing a usable length of 760 feet for the full width of 56 feet. Installation of the sector gates and operating machinery and construction of the earth chamber were completed during the year; construction of the tender's house, office, powerhouse, utilities, and appurtenances was com- menced in February 1950; contract was awarded June 20, 1950, for construction of guide walls. Excavation of a channel at Charenton floodgate was completed. Berwi'ck lock, completed April 22, 1950, is constructed of rein- forced concrete on timber pile foundation and provides a usable length of 300 feet for the full width of 45 feet. Calumet floodgates, constructed on the east and west sides of Wax Lake Outlet, were completed April 14, 1950, and work has been initiated on the ap- proach channels. Teche Ridge levee is complete. Levee enlargement is in progress between Lottie and Morgan City on the east protection levee, be- tween Catahoula and Verdunville on the west protection levee, and at Bayou des Glaises, where a setback and enlargement is in pro- gress between Hamburg and Simmesport. Maintenance of the east and west protection levees was continued. A contract was awarded June 15, 1950 for constructing Avoca Island Item E120B, a portion of levees below Morgan City, La. The. acquisition of easements in the West Atchafalaya floodway, including those for which deposits have been made into court in condemnation cases, is complete, ex- cept for an area in the vicinity of the high-level crossings at Krotz Springs, which has not yet been acquired. In the Atchafalaya floodway below the latitude of Krotz Springs, payments have been made for easements covering 94 percent of the land in Bayou Chene area and 97.9 percent in the Morgan City Front area, in- cluding those acquired by condemnation. The acquisition of ease- ments for the lands below the latitude of Krotz Springs is ap- proximately 10 percent complete. Eighty-nine claims have been presented for payment, and it is anticipated that 35 more claims will be presented during the next year. (b) Morganza floodway, Louisiana.-Work was continued on the embankment and trestle sections of the high-level crossing for the Texas & Pacific Railway's main line crossing of the floodway. Construction of the combined high-level crossing for State High- way No. 30, the Texas & Pacific Port Allen branch line, and a control structure is in progress. Construction of the embankment for the control structure is about 18 percent complete and a con- 2764 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 19 50 tract has been let and work initiated on excavation and precast concrete piling for the gated portion of the structure; invitations for bids have been issued for construction of the superstructure. Relocation of utilities continued. Payments for easements cover- ing 100 percent of the land values, including deposits into court in condemnation cases, have been made. Removal and reburial of bodies from three cemeteries in the floodway was started. Condemnation proceedings have been in- stituted to acquire comprehensive flowage easements over the old sites of cemeteries and court authority was obtained for removal of the bodies to the new sites. Judgment on declaration of taking was filed on September 13, 1948. Stipulations have been obtained by the Department of Justice from the church organizations in- volved. The cost of the land for new sites is included in the con- tract for relocation: title to such land will not be conveyed to the United States. (c) Wax Lake Outlet and Charenton drainage and navigation canal, Louisiana.-No work was done during the fiscal year. The existing project was completed in 1949. (d) Bonnet Carre spillway, Louisiana.- (See pp. 2089-2091, Annual Report for 1938.) The spillway was put in operation Feb- ruary 10, 1950, after the United States Weather Bureau predicted stages in excess of 20 feet on the Carrollton gage. The river crested at 4 p.m. on February 10, with a reading of 19.98 feet on the Carrollton gage. Bays were opened as required until February 23 when all were open. Maximum discharge as measured at the Air- line Highway Bridge was 222,800 cubic feet per second on March 4, with the Carrollton gage reading 19.5 on March 5, and averaged 156,000 cubic feet per second for the period of full operation. It is estimated that the Carrollton gage would have reached approxi- mately 21.5 feet if the spillway had not been operated. Between March 11 and 19 closure proceeded as required to maintain Car- rollton gage below 19 feet. Bonnet Carre spillway was operated from February 10 to March 19. In view of the predicted need for a full capacity operation, it was deemed advisable to improve the entrance conditions in the forebay to insure that capacity flow could be carried to prevent the river from exceeding 20 feet on the Carrollton gage. This was accomplished by the leased hy- draulic dredge Caribbean by the removal of 1,483,406 cubic yards from the forebay during the period February 24 to March 26. Maintenance of the guide levees and the spillway structure was continued. Basin improvements.-New Orleans district- (a) Atchafalaya River, La.-Enlargement of the levee below mile 30 on both banks and maintenance of the levee system continued. Operations have been retarded due to prolonged high stages of the river. (b) Bayous Rapides, Boeuf, and Cocodrie, La.-By contract 2,- 318,828 cubic yards were excavated between miles 37.8 and 47.1 for channel improvement. A contract was awarded and prelimi- nary work was started June 1, 1950, for channel improvement and realignment between miles 0 and 6.9, Bayou Cocodrie; excavation was started at the lower limits of the reach with 27,477 cubic MISSISSIPPI RIVER COMMISSION 2765 yards moved. Construction of highway bridges and relocation of facilities continued. Five timber road bridges, two foot bridges, and five concrete bridges were completed.

On July 1, 1949, 983,000 acre-feet of water remained in storage from the 1949 flood season, and on November 9, 1949, the flood basin was emptied. Maximum water elevation in the reservoir, 272.92 feet mean sea level, fourth highest stage of record, was reached March 31, 1950, when flood-control storage was 1,028,100 acre-feet. Peak inflow was about 35,000 cubic feet per second on March 14, 1950. Aver- age daily reservoir releases, varied to accord with inflow and channel conditions downstream, ranged from 0 to 5,500 cubic feet per second. On June 30, 1950, 726,090 acre-feet remained in the flood-control pool, which it was planned to release by October 15, 1950. (b) Arkabutla Reservoir.-(See table C.) The facility was oper- ated, necessary repairs to the dam and appurtenant structures were made, and malaria-control operations in the reservoir area were carried out. Contract was awarded for relocation of Com- merce and Hickhala roads in the reservoir area. A small amount of preliminary work has been accomplished on the Commerce road. Recreational facilities: Under contract, water wells were drilled. Construction and installation of picnic tables and fireplaces, com- fort station, and restoration of access roads was completed by hired labor. On July 1. 1949, 128,000 acre-feet of water remained in storage from the 1949 flood season, and on September 30, 1949, the flood basin was emptied. Maximum water elevation in the reservoir was 233.74 feet mean sea level on February 15, 1950, when flood-control storage was 356,700 acre-feet. Peak inflow was about 54,000 cubic feet per second on March 13, 1950. Average daily reservoir releases, varied to accord with inflow and channel conditions downstream, ranged from 0 to 4,700 cubic feet per second. On June 30, 1950, 49,800 acre-feet remained in the flood- control pool, which it was planned to release by September 30, 1950. (c) Enid Reservoir.-(See table C.) Under contract, construc- tion of the major portion of the embankment, spillway, and ap- purtenant works was continued and is 94 percent complete. A total 2766 REPORT OF CHIEF OF ENGINEERS, U. S.

Jonesville, La.-Constructionof the ring levee and floodwall was continued. One contract, involving the placement of 461,950 cubic yards of material in 18,428 linear feet of levee was initiated and completed during the fiscal year. Under contract, construction of three reaches of the floodwall was initiated and is 48 percent complete. (f) Levees.-(See table E-2) Memphis district. (a) -St. Francis Basin, Ark., and Mo.-(1) Wappapello Reservoir.-(See table C.) The facility was main- tained in operating condition and mosquito-control operations were, continued. Leasing of reservoir lands was continued and a patrol of the leased property was maintained. A contract entered into with the University of Missouri for a land capability survey was completed. The reservoir was nominally empty of flood storage at the beginning and end of the fiscal year and the water level was controlled in so far as possible in accordance with the malaria- control program. Maximum water surface elevation during the year was 374.83 feet on January 16, with a net flood storage of 206,000 acre-feet. Peak inflow into the reservoir was 65,100 cubic feet per second on January 5. Outflows were restricted to 10,000 cubic feet per second in accordance with the design plan of the project. Outflows of 10,000 cubic feet per second occurred Janu- ary 5-23, February 14-19, April 5-6, and May 11-15. (2') Drainage improvements.- (a) Mud Slough drainage dis- trict, Greene County, Ark.-Approximately 950,000 cubic yards of material were removed from the enlargement of existing drain- age ditches and the excavation of a new diversion ditch. The ma- terial was utilized in the construction of levees. (b) Levee district No. 4 of Dunklin County, Mo.-Approxi- mately 250,000 cubic yards of material were removed from the ex- cavation of a new diversion ditch and the enlargement of an exist- ing ditch, with the material being utilized in the construction of a new levee. (b) Memphis Harborproject.-(See table A.) During the fiscal year, 212,342 cubic yards of material were placed in the closure dam, and 5,179,723 cubic yards in the industrial embankment. The closure dam is approximately 24 percent complete, and the indus- trial embankment is 13 percent complete. Approximately 180 acres of land within the embankment limits were cleared during the year. Work was begun by contractors on wave-wash protection, permeable pile dikes, and a dry fill extension of the approach em- bankment. Approximately 15,331 squares of asphalt, 15,924 linear MISSISSIPPI RIVER COMMISSION 2769 feet of piling, and 37,500 cubic yards of earth fill material were placed in the project under these contracts. The project, as a whole, is approximately 16 percent complete. (c) Levees.-(See table E-3.) Costs for work accomplished on floodways, outlets, and basin improvements are given in table F. Waterways Experiment Station.-Operations and results dur- ing fiscal year are shown beginning on page 2800 of the Annual Report of the Chief of Engineers as a separate report. Floods-Memphis district.-Rains occurring over the upper reaches of the Mississippi River and Ohio River Basins during January and February 1950 resulted in a Mississippi River crest stage of 55.9 feet on the Cairo gage on February 15, 1950, with a corresponding maximum discharge of about 1,600,000 cubic feet per second. Floods occurring in the St. Francis River Basin during January 1950 deteriorated the substandard levees and five crevass- es occurred resulting in minor flooding. Floods occurred on the White River during January and May 1950. The floods were con- fined and the maximum stage of 29.1 feet occurred at Georgetown, Ark., on January 18 and 19, 1950. Vicksburg district.-Stages on the Mississippi River in this district were the highest since 1945. They caused considerable flooding in the Yazoo backwater area and very extensive flooding in the Red-Ouachita backwater area. A severe flood occurred on the Ouachita River during February and March 1950. and while stages on the upper Ouachita were not extremely high the stage of 47.3 at Monroe, La., was the highest since the record flood of 1945. Conditions on the lower Ouachita were further aggravated by backwater from the high Mississippi River. Minor floods oc- curred in the Ouachita Basin during January, March, and May. It is estimated that Narrows Reservoir reduced stages at Murfrees- boro during the February flood about 4 feet. In the Yazoo Basin floods occurred in January, February, and March. Stages of 31.3 feet at Swan Lake on the Tallahatchie River and 38.7 feet at Greenwood on the Yazoo River caused extensive flooding. It is estimated that completed flood-control works in the basin reduced stages 21/ feet on the Tallahatchie River and 1 foot at Greenwood on the Yazoo River. New Orleans district.-The 1950 flood was the greatest of re- cord below the latitude of New Orleans and also in the Atcha- falaya Basin from Krotz Springs to Six Mile Lake. The flood on the Lower Red River was 7.2 feet lower at Alexandria than the record flood of 1945. High stages prevailed on the Mississippi and Atchafalaya Rivers during the period January through May. The Bonnet Carre spillway was operated during the period February 10 to March 19 in order to maintain the river stage below 20 feet on the Carrolton gage. The river crested at 4 p.m., February 10, with a reading of 19.98 feet on the Carrollton gage. This flood was passed without incident. 2770 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 CONDITION AT END OF FISCAL YEAR Survey of the entire river below Cairo, Illinois was completed in 1938 and resurvey is now underway. Contoured quadrangles, general maps of the valley, and pamphlets tabulating river stages, discharge measurements, etc., have been published and are avail- able for departmental use and public distribution under prescribed regulations. Navigation and flood-control improvements completed under the existing project comprise levees, bank protection works, channel improvements (including cut-offs), floodways, outlets, and tributary basin improvements, summarized as follows: There are 2,752.5 miles of project levees, with earth work aggre- gating about 1,289,903,000 cubic yards, below Cape Girardeau and 574 miles, with earth work aggregating 127,036,000 cubic yards, above Cape Girardeau, as listed in tables E-1 through E-4. Roads have been constructed on 35 miles of levees in the New Orleans district, on 68 miles in the Vicksburg district, and on 350 miles in the Memphis district. In the New Orleans district, about 34 miles of levees on the right bank and 15 miles on the left bank are protected against wave wash by timber structures, and about 41 miles of levees on the right bank 28 miles on the left bank are pro- tected by pavement on the riverside levee slope. There are in place 193.3 miles of operative bank revetments on the Mississippi River and about 6.8 miles on the Arkansas, Red, and Ohio Rivers as listed in tables D-1 through D-3. A channel 9 by 300 feet is maintained by dredging as required during the low-water season. During the high-water season, which usually prevails from the 1st of January to the 1st of June, greater navigation depths are available between Cairo, Ill., and Baton Rouge, La. Below Baton Rouge, La., a channel 35 by 500 feet is maintained by dredging as required during the low-water season under the River and Harbor project, "Mississippi River, Baton Rouge to the Gulf of Mexico, La." Since 1928 annual maintenance and premaintenance dredging have averaged about 30,000,000 cubic yards. In years of extreme low-water of long duration, as much as 75,000,000 cubic yards may be removed in the maintenance of 9 by 300 foot channel between Cairo, Ill., and Baton Rouge, La. Channel improvements accom- plished by improvement dredging to increase the flood-carrying capacity of the river now form part of the main river channel. These improvements, which include 16 completed cut-offs, have reduced the distance from Baton Rouge to Cairo to about 737 miles from its former value of about 860 miles in 1929. The effect of channel improvement works on carrying capacity of the river is given on page 1811, Annual Report of Chief of Engineers for 1943. Continuous levee systems, except at certain railroad and high- way crossings, extend along the east and west limits of the Atcha- falaya floodway. Both Morganza floodway guide levees have been constructed. Levees have been completed along the north bank of MISSISSIPPI RIVER COMMISSION 2771 the Intracoastal waterway from the, lower Atchafalaya River to the east guide levee of Wax Lake Outlet. from the west Wax Lake spoil bank to Bayou Sale, and along Bayou Sale Ridge and Teche Ridge, thereby extending the West Atchafalaya protection levee to provide flood protection for areas generally south and west of Morgan City. (See Table E-1 for status of levees.) Floodway and basin improvements, other than levees, completed prior to 1943, are as described on pages 1884 and 1885 of the An- nual Report of the Chief of Engineers for 1943. Improvements completed since then include: In the Atchafalaya floodway: A drainage structure at Brushy Bayou in the Simmesport ring levee; floodwalls at Morgan City and Berwick; a lock in vicinity of Berwick, except approach chan- nels; floodgates at Charenton and at Calumet on the east and west sides of Wax Lake Outlet. A channel 9 by 100 feet from Bayou Boeuf to Bayou Long and through Bayou Chene from Bayou Black to Bayou Penchant has been excavated which reestablishes drain- age east of the floodway and provides an alternate route for the Gulf Intracoastal Waterway pending operation of Bayou Sorrel lock. Bayou Sorrel lock has been completed except for construction of guide walls, tender's house, office, powerhouse, utilities, and ap- purtenances, all of which are under contract. The total project for Bayou Sorrel lock is 86 percent complete. The Charenton drainage and navigation canal has been enlarged to 75-foot bottom width at -30 feet mean sea level. It serves as an outlet for drainage in- terrupted by construction of the West Atchafalaya protection levee and as a navigation connection with Grand Lake via the Charenton floodgate. Construction of high-level crossings for railroads and reloca- tion of communication lines over the floodway are in progress. Clearing the site and field work on pile tests are complete; the em- bankment section between Courtableau and Krotz Springs is 64 percent complete. Surveys and borings have been completed along the alignment of the proposed high-level crossing of United States Highway No. 190 over the West Atchafalaya floodway but no construction work has been accomplished. The Texas & Pacific Railway Co. has completed construction of the Ville Platte-Opel- ousas railway and rehabilitation of the Ville Platte-Bunkie con- nection for detouring trains to the high-level crossing. In the Morganza floodway, high-level crossing between Lottie and Krotz Springs to carry the New Orleans, Texas & Mexico Railway and Highway 190 over the floodway was completed and the following operations are in progress: Construction of the combined high-level crossing for S t a t e Highway No. 30, the Texas & Pacific Port Allen branch line, and the Morganza control structure; construction of the embankment for the control structure is 18 percent complete and work has been initiated on excavation and precast concrete piling for the gated portion of the structure; invitations for bids have been issued for construction of the superstructure. 2772 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Construction of the embankment and trestle sections of the Texas & Pacific Railway Co.'s main-line crossing over the Mor- ganza floodway is approximately 88 percent complete. Relocation of utilities continued and removal and reburial of bodies from three cemeteries located in the floodway were started. Levees extend 51 miles along the east bank and 62 miles along the west bank of the Atchafalaya River. The east bank levees are 97 percent complete and the west bank levees are 99 percent complete.. To date a total of 11,261,634 cubic yards has been excavated over 40.2 miles for channel improvement and diversion in Bayous Boeuf and Cocodrie. A new cut-off and improved channel are complete from mile 6.9 to mile 47.1. Drainage structures have been com- pleted on the south bank of Bayou Rapides and in Bayou Boeuf at Lecompte. Numerous timber and concrete bridges have been con- structed. Channel improvement in the Boeuf and Tensas Basin has been completed as follows: 60 miles in Big Creek; 0.73 mile in Big and Colewa Creek; 85 miles in Tensas River; 16 miles in Tensas Bayou, and 7.62 miles in Bayou Lafourche; improvement of these streams involved clearing and snagging, and excavation of 9,691,824 cubic yards. Three bridges crossing Big Creek were completed and an oil pipe line was relocated. Contracts have been let for channel im- provement to mile 69.69 of Big and Colewa Creek; and to mile 25 of Bayou Lafourche, and for construction of one temporary bridge and one permanent bridge, over the same stream. Plans and specifi- cations have been completed to mile 89 of Big and Colewa Creek, including the rearrangement of a multiple gas pipe line crossing, and plans for the reconstruction of six bridges and the alteration of one bridge are being prepared by the owners thereof. In the Jonesville, La., project, 59,624 cubic yards of emergency levee, were placed under section 6 of the Flood Control Act ap- proved May 15, 1928. A total of 461,950 cubic yards of material has been placed in 18,428 linear feet of ring levee. The floodwall is 48 percent complete. The Flood Control Act approved May 17, 1950, placed the project under the Flood Control, Mississippi River and tributaries, project. In the Yazoo Basin, the Sardis and Arkabutla Reservoirs are in operation. Relocation of U. S. Highway No. 51 across Arkabutla Reservoir is complete. Under contract, relocation of Commerce and Hickahala roads in the Arkabutla Reservoir area is in pro- gress. A small amount of preliminary work has been accomplished on the Commerce road. Construction of recreational facilities in Sardis and Arkabutla Reservoirs is in progress. The work consists of a change house and boat-rental concession buildings, launching ramps and boat channels, and restoration and construction of access roads at Sardis Reservoir, drilling of water wells, construc- tion and installation of picnic tables and fireplaces, at Sardis and Arkabutla Reservoirs. Plans and specifications for the Overlook Building are being revised in accordance with instructions from the Chief of Engineers. Plans and specifications for Enid and Gre- nada Reservoirs are complete. Master plans for recreational fa- MISSISSIPPI RIVER COMMISSION 2773 cilities are being prepared. Construction of major portions of embankments, spillways, and appurtenant works for Enid and Grenada Dams, and the outlet works and closure section of Enid Dam are in progress. Relocation of State Highway No. 32 in Enid Reservoir is in progress. Contracts with Panola, Lafayette, and Yalobusha Counties for relocation of county roads in Enid Reser- voir were consummated. Relocation of Illinois Central Railroad facilities and of State Highway No. 8 in Grenada Reservoir is in progress. Work on levees, drainage structures, channel improve- ments, and cut-offs in the basin is in progress. In the St. Francis Basin, the Wappapello Reservoir is complete and available for use as required. On the west bank of the St. Francis River, 44.6 miles of levee are to project grade and section. On the east bank of the St. Francis River, 56.4 miles of levee are to project,grade and section. In the Elk chute drainage district, 16.8 miles of levee are to project grade and section. The levees along Little River are 100 percent complete. Work on levees and drainage improvements is in progress. In the White River Basin area of the Memphis district, on the Augusta to Clarendon levee project, 32 miles of levee have been completed to project grade and section. The Clarendon levee is 100 percent complete. The DeValls Bluff project is complete, ex- cept the pumping plant and sump area are being redesigned to provide additional capacity. Surveys and reports prescribed under the existing project and as called for by congressional or departmental directives are made as required. Reports on tributary streams authorized pursuant to the act of January 21, 1927, when presented to the Mississippi River Commission in compliance with section 10 of the act of May 15, 1928, are considered and the conclusions and recommendations of the Commission thereon are submitted to the Chief of Engi- neers. Total costs under the existing project incurred from United States and contributed funds to June 30, 1950, were $757,833,551.- 87 for new work and maintenance (see table G-1), and $13,408,- 326.27 for emergency repairs. Similarly, total costs for construc- tion and maintenance of levees under the existing project and expenditures incurred therefor by non-Federal agencies are given in table G-2. PROPOSED OPERATIONS The balance unexpended on June 30, 1950, will be applied dur- ing the fiscal year 1951 in the prosecution of new work and main- tenance under the project. It is estimated that there will be no available balance from prior appropriations on June 30, 1951. Enlargement of the Mississippi River project levees in the New Orleans, Vicksburg, and Memphis districts to 1941 project grade and cross section will be prosecuted to the extent of available funds. About 24.5 miles of bank revetment will be constructed. Existing flood-control structures will be maintained and operated.

WATERWAYS EXPERIMENT STATION The Flood Control Act approved May 15, 1928, authorized the Chief of Engineers to establish a hydraulic laboratory and pro- vided for the annual allotment of necessary funds for the opera- tion of the laboratory and for the necessary printing to publish the scientific data collected. Pursuant to this authority the Water- ways Experiment Station was established initially in 1929, under the jurisdiction of the president, Mississippi River Commission. It has installations at Vicksburg and Jackson, Miss. By General Order No. 9, Office, Chief of Engineers, July 29, 1949, the station was transferred to the direct jurisdiction of the Chief of Engi- neers, effective August 10, 1949. Lt. Col. R. D. King, Corps of Engineers, is director. The organization comprises the Hydraulics, Soils and Concrete Research Divisions, the Corps of Engineers Research Center, and the necessary construction, 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 investigational and trafficability studies for the office, Chief of Engineers and the Engineer Research and Development Laboratories, respectively. The concrete and soils laboratories also serve as division laboratories for the Lower Mis- sissippi Valley Division. The Mississippi River Commission field printing plant is also located at the station. The Experiment Station has as its functions the experimental investigation of all problems in hydraulics, soil mechanics, con- crete, and flexible pavements presented to the station for study, as well as research and development work in those fields; techni- cal supervision of hydraulic-model testing at other Corps of Engi- neers hydraulic laboratories, including the Bonneville Hydraulic Laborartory, St. Anthony Falls Hydraulic Laboratory (St. Paul district), and the hydraulic laboratory of the Los Angeles district; prototype testing in fields of hydraulics, soils, and concrete; and technical supervision over hydraulic testing performed under con- tract with universities or other outside agencies for the Corps of Engineers. Work is performed on a reimbursable basis primarily for other Corps of Engineers offices and also, with authority 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 prototype 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 assembling of experimental engineering data from all sources, domestic and foreign, in the technical fields assigned to it; the analyzation and interpretation of these data; and the dissemina- 2799 2800 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 tion thereof to other Corps of Engineers offices through its re- search center and comprehensive technical library. In execution of this function during fiscal year 1950, four quarterly sum- maries, 44 reports of individual studies, and 2 bulletins, a hand- book for concrete and cement, and 4 translations of foreign arti- cles were distributed to Corps of Engineers and certain outside agencies. Operations and results during fiscal year.-All studies and in- vestigations at the Waterways Experiment Station are initially financed from a revolving fund, reimbursement thereof being ob- tained directly from agencies for whom the work is performed. The cost for operation of the station for the 12 months ending June 30, 1950, amiounted to $5,437,465.61, of which $4,490,566.17 was charged to establishments served for construction of models, laboratory tests, field work, etc., and $946,899.44 for permanent improvements and miscellaneous operating expenses. Of the reim- bursable work, $4,056,709.65 was charged to civil funds and $214,- 915.06 to military funds. The total cost incurred for operation of the Waterways Experiment Station to June 30, 1950, amounted to $29,003,433.40, of which $21,837,032.73 was for reimbursable operations (including military funds), and $7,166,400.67 for the cost of permanent improvements and miscellaneous operating ex- penses. PERMANENT INTERNATIONAL ASSOCIATION OF THE CONGRESSES OF NAVIGATION 1. 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 ap- propriation for the improvement and maintenance of river and harbor works. The object of the association 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. 2. The association is supported principally by member nations, but the privileges of membership are also extended to corporations, libraries, and individuals. Governments are represented by dele- gates, the number of delegates being based on the amounts re- ceived 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 delegate. Two classes of corporate membership are available. The class paying the higher annual subscription has the privilege of representation by delegate. 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. 3. The general affairs of the association are managed by a per- manent Commission with the assistance of a permanent council. The Commission is composed of delegates from the supporting governments, and the council is chosen from the members of the permanent Commission, the representation in each case being ac- cording to the amount of the annual contribution. 4. During the fiscal year 1950 the United States was repre- sented as follows: On the American Section of the Permanent Commission by Maj. Gen. Philip B. Fleming, United States Army, Retired, chairman; Brig. Gen. Gordon R. Young, Corps of Engi- neers, United States Army; Mr. J. Spencer Smith of the State of New Jersey; Col.

INTEROCEANIC CANAL SURVEYS The proposed canal route across Nicaragua extends from Brito on the Pacific via the Rio Grande Lake Nicaragua, the Rio San Juan, and the Rio Deseado to Greytown on the Atlantic, and is 173 miles long. A survey of the Nicaragua route was made in 1901, and Public Resolution 99, Seventieth Congress, approved March 2, 1929, au- thorized a further survey to bring the data up to date, as well as an investigation of additional facilities needed at the Panama Canal, to be made under the direction of the Secretary of War and supervision of the Chief of Engineers, with the aid of such civilian engineers as the President deemed advisable. The Presi- dent appointed the Interoceanic Canal Board to assist the Chief of Engineers. The Governor of the Panama Canal made the inves- tigation at Panama, and a provisional battalion of United States engineer troops made the survey in Nicaragua. The report of the Chief of Engineers, together with the reports of the Interoceanic Canal Board, of the Governor of the Panama Canal, and of the officer in charge of the survey, was submitted on December 5, 1931, and published in House Document No. 139, Seventy-second Congress. first session. An officer and one non-commissioned officer are stationed in Nicaragua to continue the collection and compilation of hydrolog- ical and meteorological data pertaining to the proposed canal. During the past fiscal year the collection of these data has in volved the operation within the watershed of Lake Nicaragua of a number of rainfall stations, also stations for making fog obser- vations, collection of evaporation data, recording lake levels and river stages, recording barometric pressure and humidity, and for gaging wind velocity and temperature. The appropriation for the investigation and survey was $150,- 000, all of which had been expended by the end of the fiscal year 1943. The River and Harbor Act, approved June 30, 1938, au- thorized the Secretary of War to continue the gathering of hydro- logical data in Nicaragua under the supervision of the Chief of Engineers as recommended in House Document No. 139, Seventy- second Congress, first session, and such incidental expenses as may be necessary in connection therewith are to be paid from ap- propriations hereafter made for examinations, surveys, and con- tingencies of rivers and harbors. The expenditures for the fiscal year ending June 30, 1950, were $9,192.00, from appropriations made for examinations, surveys, and contingencies of rivers and harbors. It is estimated that $8,750.00 will be expended in continuing the operations during the fiscal year ending June 30, 1951. 2805 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 per- formed by and through the Departments 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 commission was provided for to be composed of five commissioners to be appointed by the President, by and with the advice and consent of the Sen- ate. The necessity of performing the work through the Depart- ments 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 water-power 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 af- fecting navigation have been approved by the Chief of Engineers and the Secretary of Army. There is further provision whereby 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.

The laws enacted for the preservation of the tidal waters of New York Harbor, its adjacent or tributary waters, and the wat- ers of Long Island Sound are administered by the Supervisor of New York Harbor, a line officer of the Navy, under the direction of the Secretary of the Army. The supervisor is charged under the laws with the duties of preventing any obstructive or injurious deposits in the waters under his jurisdiction and the prevention of any interference with safe navigation of the channels of the harbor by deep-draft vessels. The laws relating to the supervision of New York Harbor are acts of Congress of June 29, 1888, (25 Stat. 209), amended by section 8 of act of May 28, 1908 (35 Stat. 424-426) ; act of Con- gress of August 18, 1894 (28 Stat. 360) ; act of Congress of May 28, 1908 (35 Stat. 426); act of Congress of February 16, 1909 (35 Stat. 623); and act of Congress of June 7, 1924 (Oil Pollu- tion Act, 1924, 43 Stat. 604). Operationsand results during fiscal year.-Notices to acquaint navigation interests with the laws and regulations relating to the, 2812 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 harbor were issued with a view to obtaining cooperation in their administration; dumping grounds for stone, ashes, mud, cellar dirt, sewerage sludge, and other refuse were designated; and 2,867 permits were issued for the removal of approximately 26,- 846,264 cubic yards of material. Soundings were taken at frequent intervals over the designated dumping areas to insure that sufficient depth of waters was main- tained. Supervision was exercised by means of inspectors and patrols. Patrols were maintained to insure that no material was deposited at places other than the designated dumping grounds and to keep the main channels free of any interference to the safe navigation of these channels by deep-draft vessels; to prevent the discharge into navigable waters of waste oil and sludge, rubbish, and waste resulting from loading operations. The amounts of material reported to have been removed were constantly checked by the patrols.

ANACOSTIA PARK AND THE RECLAMATION AND DEVELOPMENT OF ANACOSTIA RIVER AND FLATS FROM THE MOUTH OF THE RIVER TO THE DISTRICT LINE, DISTRICT OF COLUMBIA District engineer: Col. Henry C. Wolfe, Corps of Engineers, to May 31, 1950; Lt. Col. H. R. Davis, Corps of Engineers, acting district engineer, to June 27, 1950; and Col. Alan J. McCutchen, Corps of Engineers, since that date. Location.-The Anacostia River enters the Potomac River at Washington, D. C. Previous projects.-Forthe part of the project below the Ana- costia Bridge, which is also a river and harbor improvement, see Annual Report of the, Chief of Engineers for 1919, page 553, under heading "Existing project." For a description of the previous projects for the improvement extending upstream from the Ana- costia Bridge see Annual Report of the Chief of Engineers for 1923, page 1990 under heading "Existing project." Existing project. This provides for the improvement of the river and for the reclamation and development of the adjacent flats from the mouth of the river upstream to the District of Columbia boundary line, a distance of about 61/3 miles, to afford a river channel 15 feet deep in the section between the foot of Fifteenth Street SE., and Massachusetts Avenue, 9 feet deep thence to Benning Road. The section from the mouth upstream to the foot of Fifteenth Street SE., was dredged to a depth of 24 feet under a river and harbor project. The dredged material is to be used for fills. The project includes a constant-level lake or lateral basin on the west side of the river, to be known as Lake Kingman, and a smaller MISCELLANEOUS CIVIL WORKS 2815 lake on the east side of the stream. The normal surface elevation of the lakes is to be 2 feet above mean low tide, and they are to be dredged to a depth of 6 feet. A culvert or small bridge is to be constructed over Lake Kingman on the line of Benning Road, and a lock and bridge is to be built at the lower end of Lake Kingman. Influent and effluent gate-control works are to be constructed to provide circulation and maintain a constant level in both lakes. Masonry sea walls on a riprap substructure are to be construc- ted along the tidal channel of the river to extend 6 feet above mean low water; the walls of the lakes are to extend 3 feet above mean low water or 1 foot above the level of the lake. A portion of the reclaimed tract is to be set aside for develop- ment by the Agriculture Department for a national arboretum and botanical garden. A strip of water-front land on the right bank of the river between the Anacostia Bridge and the Pennsylvania Railroad freight bridge is to be set aside for commercial purposes. The estimated cost of the project to the Federal Government and the District of Columbia is $4,125,000 (October 1923). To this must be added $150,000 appropriated by act approved July 3, 1930, and $15,000 appropriated by act approved April 4, 1938, for cost of land not covered in estimated cost of project because of increased commercial valuation and subsequent adverse court decision as to United States ownership.

The District of Columbia Appropriation Act approved March 2, 1911, 36 Stat. 1005 (Public No. 44), in authorizing the project provided that the work is to be carried on under the supervision of the Chief of Engineers, United States Army, upon plans pre- pared under the direction of, and to be approved by, a board of engineers to consist of the Engineer Commissioner of the District of Columbia, the officer in charge of public buildings and grounds, and the engineer officer in charge of the improvements of the Potomac River. 2816 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Executive Order No. 6166, dated June 10, 1933, transferred the functions of the Office of Public Buildings and Grounds to the National Park Service, Department of Interior. Accordingly, the Director of the National Park Service has become a member of the board of engineers in lieu of the officer in charge of public buildings and grounds. Local cooperation.-The funds for this project have been ap- propriated by the District of Columbia appropriation bills, which through the fiscal year ended June 30, 1920, provided for half of the expense to be borne by the District of Columbia. From that date to June 30, 1924, the expense was borne 60 percent by the District of Columbia and 40 percent by the United States. Be- ginning July 1, 1924, the District of Columbia paid all required above the lump sum appropriated from United States revenues. Operations and results during fiscal year.-Construction work on the project was deferred during the war, and has not been resumed due to lack of appropriations. Reestimating the project was continued throughout the year at a cost of $170.34. Total cost for the year was $170.34, and total expenditures were $12.35, all applied to new work. Condition at end of fiscal year.-The existing project is 70 percent completed.

Location.-The diversion dam and raw-water intakes on the Potomac River at Great Falls, 131/2 miles northwest of Washing- ton, D. C.; the two collecting conduits; part of the Dalecarlia re- ceiving reservoir; and a booster pumping plant that lifts the water from the forebay to the main body of the Dalecarlia reservoir are located in Maryland. All other structures of the water-supply sys- tem including part of the raw-water collecting system, the purifi- cation facilities, pumping stations, storage reservoirs, and trans- mission mains are located within the District of Columbia. (See U. S. Geological quadrangle, Washington and vicinity.) The control of the water-supply system is vested in the Chief of Engineers. (See acts of March 3, 1859, and March 2, 1867, and sec. 1800, Revised Statutes.) Existing projects.-The existing projects provide for (a) oper- ation, maintenance, repair, and protection of the water-supply facilities; their accessories; the several reservations comprehend- ing collection, treatment, purification, pumping, transmission, and storage; the maintenance and protection of MacArthur Boulevard; and the maintenance of water meters on Federal services all as authorized by law, and (b) the planning and the construction of increased supply facilities in accordance with House Document No. 480, Seventy-ninth Congress, second session (August 15, 1945), as covered by Public Law 533, Eighty-first Congress, second ses- sion, approved June 2, 1950. By act, Public Law 378, Sixty-fourth Congress, approved March 3, 1917, the furnishing of water to adjacent Maryland areas from the Washington water-supply system was authorized by the Con- gress; by act, Public Law 119, Sixty-ninth Congress, approved MISCELLANEOUS CIVIL WORKS 2819 April 14, 1926, the furnishing of water to Arlington County, Va., from the Washington water-supply system was authorized by the Congress; and, by act, Public Law 118, Eightieth Congress, ap- proved June 26, 1947, the furnishing of water to Falls Church, Va., or to any other competent State or local autiority in the Virginia metropolitan area, similarly, was authorizel. A description of the District of Columbia water-supply system and of previous capital-improvement and operation-and-mainte- nance 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, by the Washington district, Corps of Engineers; and in House Document 480, Seventy-ninth Congress. Local cooperation.-Priorto 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 July 1, 1916, the expenses of construction, operation, and maintenance were paid one-half by the United States and the other half out of the general revenues of the Dis- trict of Columbia. From July 1, 1916, to June 30, 1924, the ex- penses of construction were paid 60 percent out of the general revenues of the. District of Columbia and 40 percent by the United States. From July 1, 1924, to June 30, 1927, expenses of construc- tion of the Washington Aqueduct were paid wholly out of the general revenues of the District of Columbia to which the United States contributed annually a lump sum. The expenses of operation and maintenance, since July 1, 1916, to date, have been paid wholly out of the water revenues of the District of Columbia. From July 1, 1927, to date, all expenses for construc- tion have been paid out of the water revenues of the District of Columbia. By act approved June 10, 1920, $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 and this report was the basis for the im- provements constructed from 1922 to 1927. Included in the Dis- trict 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 Colum- bia and metropolitan area." This report, published as House Docu- ment 480, Seventy-ninth .Congress, contains the comprehensive plan and program for the improvements and additions to the water system to meet safely and adequately the anticipated water de- mands to the year 2000. Annually since July 1, 1916, on a percentage basis, and since July 1, 1924, on a lump-sum basis, the United States has contri- buted to the support of the District of Columbia but no part of such annual percentage or lump-sum contributions has been allocated to the water fund, District of Columbia, before July 1, 1947. 2820 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Beginning with the fiscal year 1948, pursuant to act, Public Law 195, Eightieth Congress, approved July 16, 1947, an annual pay- ment of $1,000,000 was authorized for water consumed by the Federal Government. This sum is taken from the annual lump sum contribution of the United States to the District of Columbia. Public Law*533, Eighty-first Congress, second 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 fi- nance 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 edi- tion, title 1943, ch. 15). Operations and results during the fiscal year:-An uninterrupt- ed and adequate supply of purified water was furnished to the District of Columbia; to Arlington County, Va.; and to Federal establishments in Arlington County, Va., and in Montgomery and Prince Georges Counties, Md. The maximum daily consumption was 241,675,000 gallons and the average daily consumption was 171,122,300 gallons. Based upon the estimated average number of consumers of 925,000 in the District of Columbia and 135,000 in Arlington County, the average per capita daily consumption was 161.44 gallons. The average daily consumption in the District of Columbia alone was 157,860,000 gallons or an average per capita consumption of 170.65 gallons per day. The average daily amount of water furnished to Arlington County and Falls Church, Va., was 11,245,000 gallons or an average per capita consump- tion of 76.41 gallons per day. The gross cost for the supply furn- ished the Virginia communities was reimbursed to the water fund, District of Columbia. The average daily consumption of water in all Federal Government establishments including parks, zoological garden, etc., was 24,927,450 gallons. A total of 736,304,000 gallons or an average of 2,017,271 gallons per day, was delivered to Mary- land communities during the fiscal year 1950 by the water divi- sion, District of Columbia, through connections to the Washington Suburban Sanitary District's system. The average turbidity of the raw water from the Potomac River was reduced from 98 parts per million to 0.00 part per million and the average bacterial content was reduced from 1956 to 1 per milliliter. Analyses were made for bacterium colon on 151,989 tubes of water taken from 112 sampling points in the purification and distribution systems. After sterilization of the filter effluent, the average number of bacterium colon per 100 milliliters was found to be 0.008 at Dalecarlia and 0.019 at the McMillan filter plant. The average alkalinity of the filtered water was 59 parts per million and the average pH value was 7.6 parts per million from both the Dalecarlia and McMillan filter plants. The average hard- nessi was 95 parts per million from Dalecarlia and 93 parts per million from McMillan. The direct operating costs of water treated and delivered to the system per million gallons was $23.34 as compared with the cost of $19.41 per million gallons in fiscal year 1949. The overall cost MISCELLANEOUS CIVIL WORKS 2821 of water delivered, including depreciation and interest was $46.04 per million gallons as compared with $41.46 in 1949. Construction work authorized with "no year" funds not pre- viously reported as completed, was as follows: Repair and rehabilitation of McMillan filter plant, 80 percent; McMillan filter plant improvements, 85 percent; utility reloca- tions, Dalecarlia, 90 percent; mixing and sedimentation basin No. 4 at Dalecarlia, 100 percent; conduit repairs (periodic) 100 percent; flocculation equipment for existing coagulation basins, 80 percent; purchase and installation of federal meters (periodic) 90 percent; circulating facilities in first and second High service reservoirs, 65 percent; remodeling of Georgetown reservoir, 16 percent and acquisition of supplementary land, 9 percent. The preparation of plans for capital outlay projects for increas- ing the water supply progressed as follows: Thirty-million-gallon clear-water basin at Dalecarlia, 75 per- cent; reservoir at Fort Reno (first half) 95 percent; 11/2-million- gallon Reno water tower, 30 percent; Fourth high service pump- ing station at Reno, 10 percent; 48-inch pipe line from Dalecarlia to Reno, 65 percent; crosstown interconnecting main from Dale- carlia to low-service area (first half) 8 percent; McMillan filter plant improvements, 95 percent: new chemical building and op- erating center at McMillan, 10 percent; utility relocations at Dale- carlia (periodic) 100 percent; Georgetown reservoir improve- ments, 95 percent; Dalecarlia pumping station, 15 percent; office extension, 95 percent; six filters addition to Dalecarlia, 100 per- cent; collector mains at McMillan 100 percent; Little Falls drain- age channel, 40 percent; Great Falls intake structure, 5 percent; shops and storehouse at Dalecarlia 100 percent; Federal meters, 50 percent; land acquisitions, 20 percent; and conduit repairs, 40 percent.

Visitors:-1,623 persons were conducted through the water treatment and pumping plants and the bacteriological and chem- ical laboratories. College engineering and science students num- bered 845 and public school pupils 668, public officials 25. foreign visitors 41, and others 44. Of the 41 foreign visitors 28 came from 13 neighboring countries in the Western Hemisphere, 2 from Europe, 4 from the Near East, and 7 from the Far East. Control:-The annual appropriation act contained the follow- ing: 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 ap- propriations 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 with the exception of the McMillan filter structures on which repairs are in progress were in a generally good condition. However, the demands upon the supply system have exceeded its nominal capacity and, for several years, its operation has been in the overload category. During maximum consumption demands periods, the basic raw water supply was exceeded and emergency equipment had to be utilized. Public Law 533 enacted by the Eighty-first Congress, second session permitting borrowing from the Treasury of the United States will now enable the major capital improvements program recommended in House Document No. 480 to proceed after delay or deferment due to an insufficiency of funds which had put the program of construction for increased capacity four years behind schedule.

Bristor, Corps of Engineers, to May 10, 1950, and acting district engineer since, that date. Surveys-Great Lakes.-The existing general project, stated in detail in the Annual Report for 1907, pages 844 to 850, comprises the following work: Ascertaining and charting depths in all signi- ficant regions of the Great Lakes to a plane 30 feet below the adopted low-water datum of the open lakes and 25 feet below the corresponding datum in the channels of the connecting rivers, completion of triangulation and precise leveling needed to control the areas under survey, river-discharge measurements, investiga- tions of lake levels, magnetic surveys in and near main vessel courses, and prompt examination of areas where obstructions to navigation have been reported. Surveys-New York State canals.-The Sundry Civil Act of March 4, 1911, provided that the, survey be extended to include the lakes and other natural navigable waters of the New York State canals. The project contemplated revision and adjustment by field reconnaissance of all existing survey data pertaining thereto, supplemented by such additional topographic and hydro- graphic surveys as might be required for the publication of naviga- tion charts of these waters. Field work under this project has been completed and the full set of charts has been published. Surveys-Lake Champlain.-The scope of operations was ex- tended by the Sundry Civil Act of June 23, 1913, to include Lake Champlain. Surveys of harbors and other important areas were MISCELLANEOUS CIVIL WORKS 2825 commenced during the field season of 1928. This work was com- pleted in 1933. Surveys-Boundary waters between the Lake of the Woods and Lake Superior.-The Sundry Civil Act of August 1, 1914, extended the work of the Lake Survey to include these waters. The project provides for the preparation of navigation charts of the United States waters of the Lake of the Woods and Rainy Lake,, complete with hydrography. The project work was completed in 1938. A series of maps without hydrography, extending from Rainy Lake to Pigeon River, was authorized September 8, 1949, and com- pleted in 1950. Charts.-The project for chart preparation provides for gen- eral, coast, river, harbor, and locality charts of the waters above mentioned in accordance with the needs of navigation and modern reproduction practice. The number of charts necessary is not fixed. Changing requirements of navigation may render new charts desirable or make old charts unnecessary. Bulletins.-The work pertaining to the Bulletin of the Survey of Northern and Northwestern Lakes consists in publishing an- nually in April a revised volume of coast and harbor descriptions, etc., and seven monthly supplements from May to November, giv- ing changes and additions. Investigation of lake levels.-The present program of field work and office studies for essential hydraulic investigations of the Great Lakes approved January 21, 1935, embraces current meter work for the revision of flow equations as necessary in the con- necting and outflow rivers; field determinations and office studies pertaining to effects of improvements, made or proposed, and of diversions at various localities; compilations and studies relating to rainfall, run-off, evaporation, water temperatures, ice retarda- tion, earth tilt, and other phenomena affecting the levels of the Lakes; and the installation and operation of gages to maintain records of water-surface elevations and to adjust datum planes for river and harbor improvements. Estimated cost of the work.-The cost of maintenance work, which includes revision and reissue of charts, revisory surveys of harbors and open lake areas, and miscellaneous investigations of obstructions to navigation, observation and study of lake levels, publication of bulletins, supplements, and notices to mariners, and other continuing necessary activities, is estimated at $475,000 for the fiscal year 1951. Operations and results during the year.-Surveys.-Five par- ties were in the field on July 1, 1949, and operations were con- tinued until early November. Five parties were organized in the spring of 1950. Field work was started in April and has been con- tinued to the end of the fiscal year. Localities and character of work are as follows: Lake Superior: Triangulation station recovery was done on the south shore in the vicinity of Whitefish Point. St .Marys River: Examination for chart revision was begun. Triangulation station recovery was done in the vicinity of Sault Ste. Marie. 939127--51-vol. 2--88 2826 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Lake Michigan: Examinations for chart revision were made around the entire lake. Triangulation station recovery and other control work was done in Green Bay preparatory to making new soundings. Lake, Huron: Inshore sounding surveys were made on the west shore from Point Lookout to Harrisville. Examinations for chart revision were made at selected harbors. Lake Erie: Inshore sounding was done between Sandusky and Port Clinton, Ohio, and among the islands in the west end. Charts.-During the year ending June 30, 1950, revised edi- tions of 39 charts were prepared and issued, and 15 new charts were compiled and published. The number of charts sold during the year was 54,081. The proceeds of sales, amounting to $23,746.45, were deposited to the credit of the Treasurer of the United States. A total of 13,196 charts were issued for official use. Publication of bulletin, etc.-The descriptive bulletin publishes detailed information concerning coast lines, harbors, channels, menaces to navigation, and miscellaneous features pertinent to navigation, of a character supplementary to the charts but too voluminous to be incorporated thereon. The book is revised an- nually and seven supplements thereto are issued during the navi- gation season. Copies are sold to the public and issued to Govern- ment agencies. Supplements Nos. 3 to 7 to Bulletin No. 58 were issued between July and November 1949. Bulletin No. 59 was prepared during the winter and the printed edition received from the Government Printing Office in the spring. Supplements Nos. 1 and 2 to the latter were prepared and printed in May and June 1950. In addition to the above publications, mimeographed notices of the monthly mean stages of the Great Lakes have been sent to newspapers, vessel interests, and Government agencies to which the information is of concern. Investigation of lake levels.-To afford a continuing record of the varying elevations of the water surfaces of the Great Lakes and their connecting and outflow rivers, 20 self-registering gauges and 10 staff gauges are maintained at regular stations. Measurements of the flow of the St. Clair River and Detroit River were made. and precise levels were run in several sections along both rivers. Studies have been made relating to water levels and hydraulic problems of the Great Lakes system and to the effects upon lake levels of improvements for navigation.

The total expenditures during the year, after deducting re- ceipts from reimbursements and sales, were $404,420.31. Condition at end of fiscal year.--The present project for sur- veys on the Great Lakes was formulated in 1907. The project for new work on the Great Lakes, on New York State canals, on Lake Champlain, on Lake of the Woods, on Rainy Lake and other Min- nesota-Ontario boundary waters has been completed, and present operations consist of maintenance. Lake survey charts are on sale at the United States lake survey office in Detroit, at the Corps of Engineers district offices in Buf- falo and Chicago, and at the Canal office in Sault Ste. Marie, Mich. Sample sets are on file at the Corps of Engineers offices in Duluth, Milwaukee, Albany, and New York City, and at the office of the Chief of Engineers in Washington, D. C., for reference. From 1882 to June 30, 1950, a total sum of $357,077.85 was derived from the sale of charts and deposited in the United States Treasury. In all, 1,587,068 charts have been sold and issued for service. Cost of new work under previous projects total $3,973,897.31. Under the existing project a cost for new work of $2,755,913.96, plus a cost for maintenance of $4,773,970.77, give a total cost of $7,529,884.73. The total expenditures under the existing project up to June 30, 1950, amount to $7,510,505.52. Proposed operations.-The balance unexpended June 30, 1950, $32,748.40, plus accounts receivable $17, plus an anticipated allotment of $325,000, a total of $357,765.40, will be applied as follows: Accounts payable June 30, 1950 ............................. ,$19,396.21 Maintenance: Revisory surveys ................................... 130,000.00 Control surveys .... .................................. 33,000.00 Hydraulic studies, maintenance of gauges, and reduction of records ............................................. 44,300.00 2828 REPORT OF CHIEF OF ENGINEERS, U.

CROIX RIVER BOARD OF CONTROL Constitutionand duties.-The Board was organized pursuant to conditions in the orders of the International Joint Commission ap- proving the maintenance and operation of the dam built by the St. Croix Water Power Co. and the Sprague Falls Manufacturing Co., Ltd., across the St. Croix River at Grand Falls in the State of Maine, and subsequent agreements reached between the Govern- ments of the United States and the Dominion of Canada. The Board is charged with the duty of formulating and adminis- tering 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 to 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 Canadian Cottons, Ltd., extending across the St. Croix River from MISCELLANEOUS CIVIL WORKS 2829 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. 3. That the operation of the dam, insofar as is necessary to ensure the ob- servance 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 1950 were Mr. T. M. Patterson, Water Resources Division, Department of Resources and Development, Ottawa, Ontario, and Col. James H. Stratton, Corps of Engineers, serving as United States member until October 24, 1949, when he was succeeded by Col. B. M. Harloe, Corps of Engineers, who served until January 19, 1950, when he was succeeded by Lt. Col. Gunnard W. Carlson, Corps of Engineers. Operations during the fiscal year.-Supervision was maintained and inspections made to ensure that the regulations of the Inter- national Joint Commission were carried out. Proposed operations.-Only such correspondence and inspec- tions as may be necessary to carry out the regulations of the In- ternational Joint Commission. THE INTERNATIONAL LAKE CHAMPLAIN BOARD OF CONTROL Constitution and duties.-The Board was organized pursuant to the provisions of the orders, dated June 10, 1937, of the Inter- national Joint Commission, approving the construction and opera- tion of certain remedial works in the Richelieu River at Fryers 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 the fis- cal year 1950 were Mr. T. M. Patterson of the Department of Resources and Development, Water Resources Division, for Cana- da, and Col. W. W. Wanamaker, Corps of Engineers, succeeded by Col. E. P. Ketchum. Corps of Engineers, for the United States. Operations during the fiscal year.-None. The construction of the Fryers 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. Proposed operations.-Only such administrative work and in- spections as may be necessary to carry out the regulations of the International Joint Commission will be performed. NIAGARA CONTROL BOARD Constitution and duties.-The Niagara Control Board was con- stituted in August, 1923, to measure and supervise the diversion 2830 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 of waters from the Niagara River so that the, level of Lake Erie and the flow of the stream shall not be affected, in accordance with the provisions of article V, treaty between the United States and Great Britain-boundary waters between the United States and Canada--May 13, 1910. Article V of the treaty limits the author- ized daily diversion by Canada to 36,000 cubic feet per second and by the United States to 20,000 cubic feet per second. By an exchange of notes between the Secretary of State and the Canadian Minister an additional diversion of 5,000 cubic feet per second for Canada was authorized October 14, 1940. Senate Executive Report No. 8, Seventy-seventh Congress, first session, authorized June 12, 1941, for defense purposes, additional diver- sion of 3,000 cubic feet per second for Canada, and 5,000 cubic feet per second for the United States. A further exchange of notes authorized November 28, 1941, additional diversions of 7,500 cubic feet per second for the United States, and 6,000 cubic feet per second for Canada. An additional emergency diversion of 4,000 cubic feet per sec- ond for Canada was authorized by a further exchange of notes on May 3, 1944. On December 16, 1948, an exchange of notes pro- vided for the continuation of the 4,000 cubic feet per second emer- gency diversion, authorized in the exchange of notes on May 3, 1944, and an increased Canadian diversion through the DeCew plant of 2,500 cubic feet per second during the non-navigation sea- son until April 15, 1951. Members of the Board.-The Board consists of two members, one representing the Dominion of Canada and one representing the United States. During the past year the Canadian represen- tative was Mr. Norman Marr, Chief Hydraulic Engineer, Domin- ion Water and Power Bureau, Ottawa. In letter to the Secretary of State dated February 26, 1944, the Secretary of the. Army desig- nated the district engineer, Buffalo, N. Y., as ex-officio United States member of the International Niagara Board of Control. Col. Frank H. Forney has been district engineer since July 6, 1949. Operations during the fiscal year.---The Board received daily reports of operations of the six hydroelectric generating stations on the Niagara River, all of which divert water above the Falls. These reports, submitted in form prescribed by the Board, show- ing for each hour the units in operation, the power output of each station, and quantities of water diverted, were checked by the Board. Monthly and annual summaries were prepared. Weekly and intermittent inspections of all plants were made by representatives of the Board members, jointly and individually, to obtain independent watt-meter readings of power output and to assure that all provisions of article V were complied with. One unit of the new DeCew Falls Hydro-Electric Power De- velopment was placed in operation October 15,1943. The second unit was placed in operation September 26,1947. Reports of daily diversions from the Niagara River by the DeCew plant beginning September 29, 1943, and continuing since that date have been re- ceived by the Board. Joint inspections of the DeCew plant were MISCELLANEOUS CIVIL WORKS 2831 begun on February 9, 1944, and have continued at bi-weekly inter- vals since that date. Five hydro-electric generators in the Schoellkopf 3A Plant of the Niagara Falls Power Company were converted from D.C. to A.C. The conversion was started on March 1, 1949, and the last of the units was placed in commercial operation May 1, 1949. The rating curves for these, units were checked by Gibson tests made by the power company on December 17 and 18, 1949. The Gibson tests were witnessed by the Board and their representatives. Records of water levels in the Niagara River above and below the Falls were obtained by means of four self-registering gauges on the United States side. On November 4, 1940, additional diversions by Canada were begun under the agreement between the Secretary of State and the Canadian Minister. On June 13, 1941, and November 28, 1941, additional diversions by Canada and the United States were begun under the authorization in the Senate executive report and the exchange of notes cited above. SPECIAL INTERNATIONAL NIAGARA BOARD In 1926 the Niagara Control Board was enlarged by the addi- tion of two members-Dr. J. Horace McFarland being the addi- tional United States member and Dr. Charles Camsell the ad- ditional Canadian member-for an extended investigation into the preservation of the scenic beauty of the Falls and analysis of all factors relative thereto. The Enlarged Board was constituted into a Special International Niagara Board for the purpose of carrying on this investigation. On December 11, 1929, the Special Inter- national Niagara Board submitted its final report to the two Gov- ernments, with recommendations in regard to remedial works, additional diversions, etc. This report was printed as Senate Docu- ment No. 128, Seventy-first Congress, second session. On January 17, 1931, a large mass of rock forming a part of the crest of the American Falls collapsed and fell into the gorge. A supplementary report, which reviewed the basic findings of the Board as presented in its final report of December 11, 1929, and which discussed the relationship of the rock fall to these findings was prepared and submitted on Noveliber 10, 1931. This supple- mentary report confirmed the conclusions and recommendations made in the final report. This was the last investigation under- taken by the Special International Niagara Board. 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 mainte- nance of the weir and, among other things, provided for a board of engineers to pass upon and control the new and old works involved. 2832 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 Members of the Board.-The Canadian member of the Board of the fiscal year was Mr. Norman Marr, Chief Hydraulic Engi- neer, Dominion Water and Power Bureau. In letter to the Secre- tary of State dated February 26, 1944, the Secretary of the Army designated the district engineer, Buffalo, N. Y., as ex-officio United States member of the International Massena Board of Control. Col. Frank H. Forney has been district engineer since July 6, 1949. Operations during the fiscal year.-The Board kept in touch with conditions by means of inspections and with respect to the diversion by means of monthly reports of the power company, showing the amount of water diverted and powerhouse perform- ance from day to day. The weir was inspected by the district engineer on August 28, 1949. INTERNATIONAL LAKE SUPERIOR BOARD OF CONTROL Constitution and duties.-The Board, organized 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 near as possible between elevations 602.1 and 603.6 feet above mean tide at New York. Members of the Board.-The members of the Board were Mr. Norman Marr, for Canada; Col. Louis J. Rumaggi, Corps of Engi- neers, until May 21, 1950, and Lt. Col. John D. Bristor, Corps of Engineers, since that date, for the United States. Operations during the fiscal year.-The Board kept in touch during the year with conditions pertaining to the diversion, through representatives of the United States and Canada on the ground, and by means of regular and systematic reports of the water levels in Lake Superior, in the channels of St. Marys River above and below the Sault Locks and in Lake Huron. Records of discharge at Sault Ste. Marie through the rapids, navigation ca- nals, and power plants were also systematically reported to the Board. Changes in the rate of outflow from Lake Superior were directed as the need therefor was indicated by water level records. During May and June unusually high supplies reached the Lake and, although in mid-June arrangements were made to discharge water from the Lake at the maximum rate, it appears (at the end of the fiscal year) that the crest of the seasonal stage cycle may, in August or September 1950, reach 603.6. A joint inspection of the compensating works was made by the then members of the Board during October 1949. LAKE OF THE WOODS WATERSHED The members of the International Lake of the Woods Control Board, the International Rainy Lake Board of Control, and of the International Prairie Portage Board of Control for the fiscal year were Mr. I. R. Strome, engineer, Dominion Water and Power Bu- reau, for Canada, and Col. David A. Morris, Corps of Engineers, for the United States. MISCELLANEOUS CIVIL WORKS 2888 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 estab- lishment 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 ap- proval 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. Operations during 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 em- powered to adopt such measures of control as to 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 of 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 provided for a method of regulation as recommended by the Rainy Lake Board of Control. The order provides for certain levels dur- ing the various seasons of the year as well as control of outflows, with the view to securing the most advantageous use of the water in total to the various interests. Operationsduring 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 approval of the plans by the Department of the Army and the International Joint Com- mission, the Board has been retained to advise the Commission 2884 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1950 further regarding progress of construction and regarding any other matters which might arise concerning this project. The United States Forest Service, which is constructing the dam, postponed work on this project during the war and at this time is merely maintaining the cofferdam, which was completed in 1941.
