FLOOD CONTROL RESERVOIR OPERATIONS A coordinated system of reservoirs, many of which are multi- purpose in nature and all containing significant amounts of storage for flood control purposes, has been established in five major flood producing basins in New England. During periods of flood flows, regulation of reservoirs is fully coordinated within each basin dependent upon its location in the watershed, its available storage capacity and origin of flood. In addition to flood control releases, water supply and flow augmentation releases were made from selected reservoirs. Regulation within each basin during the fiscal year was as follows; Blackstone River Basin The West Hill reservoir was regulated in December 1969, February and April 1970 and flood storage used ranged from 10 to 18 percent. Connecticut River Basin In August 1969 Colebrook River, Sucker Brook and Mad River reservoirs were operated, resulting in storage used from 8 to 18 percent. During November-December 1969, Ball Mountain, Townshend, Tully and Colebrook reservoirs utilized storage from 8 to 16 percent. In February 1970, Townshend, Otter Brook, Birch Hill, Conant Brook, Knightville and Littleville reservoirs utilized storage ranging from 7-12 percent. During April 1970, all reservoirs were operated and stored various amounts ranging from a minimum of 3 percent at Union Village to a maximum of 20 percent at Ball Mountain. During May 1970, Otter Brook, Knightville and Colebrook River were regulated with 8 to 15 percent of storage used. In addition, releases for white water canoeing occurred at Ball Mountain during October and May. Water supply and fishery releases were discharged from Colebrook River. Housatonic River Basin Thomaston was regulated in August 1969 and April 1970 and storages used ranged from 16 to 18 percent. During February and April 1970, Hop Brook reservoir stored floodwaters and utilized storage up to 18 percent. In August 1969 Black Rock reservoir (still under construction) filled to about 10 percent. The other 4 reservoirs, which are ungated, operated automatically and stored waters during August 1969, February 1970 and April 1970, using up to 18 percent of available reservoir storage. Merrimack River Basin In July 1969 Franklin Falls dam was operated and 11 percent of storage capacity was utilized. All reservoirs except Franklin Falls stored floodwaters in February 1970, varying from 6 percent of capacity at Everett to 36 percent at MacDowell. In 451-584 0-72-4 April Franklin Falls stored 8 percent and Hopkinton 11 percent. Thames River Basin All six reservoirs were operated in February and April 1970 with storage utilized ranging from 15 percent at Buffumville to 42 percent at West Thompson. In addition, releases were made from East Brimfield during the summer months to augment low flows. 59. HURRICANE BARRIER OPERATIONS Four hurricane barriers, located along the southern coast of New England, protect coastal communities from tidal flooding associated with hurricanes or severe coastal storms. The Corps operates the Stamford, Conn. and New Bedford-Fairhaven, Mass. barriers since navigation is involved. The Fox Point, R.I. and Pawcatuck, Conn. barriers are operated by the local communities. A brief resume of operations follows; Stamford Barrier The barrier gate was closed on 11 occasions, all due to coastal storms. The maximum ocean tide rose to 7.8 feet msl.

Jetty has surpassed its capacity as a sand entrapping agent and when examined in June 1969, was found to be in poor condition. 7. GREAT LAKES TO HUDSON RIVER WATERWAY, N.Y. Location. Consists of portion of New York State Barge Canal system extending from Hudson River at Waterford to Oswego Harbor on Lake Ontario. (See Lake Survey Charts 183, 184, and New York Canal Charts.) Existing project. Provides for allotment of Federal funds to the State of New York for expenditure under suitable Federal control and supervision in improvement of canal connecting Lake Ontario with the Hudson River. Improvement provides for a depth of 13 feet below normal pool level through all locks between Waterford and Oswego, deepening between locks to 14 feet below normal pool level, widening at bends and elsewhere, and increasing overhead clearance to 20 feet at maximum navigable stage at bridges and other overhead structures. Widths of channel to be provided under project are 104 feet in earth cuts, 120 feet in rock cuts, 200 feet in river sections, with widening at bends and elsewhere as may be necessary. Waterway included in this project is about 184 miles long, of which 160 miles are in Erie Canal from Waterford to Three Rivers Point and 24 miles are in Oswego Canal from Three Rivers Point to Oswego. Cost estimate for new work is $33,900,000 (July 1968). No estimate of maintenance with Federal funds is included, as maintenance of canal is not a part of Federal project. (See Table 2-B for authorizing legislation.) Local cooperation. Fully complied with. Terminal facilities. State of New York provided terminal and transfer facilities at all important points along Erie and Oswego Canals, and at Buffalo, Troy, Albany, and New York Harbor. Freight-handling equipment, as well as storage and dock facilities, is governed by requirements of particular locality. Stateowned terminal at Oswego has a grain elevator with a capacity of 1 million bushels. Albany Port District Commission erected a grain elevator at Albany with a capacity of 13,500,000 bushels. Port of New York Authority grain terminal in New York Harbor on Gowanus Bay has a capacity of about 1,800,000 bushels. The grain terminal on Gowanus Bay is not being used or operated. Terminals at Buffalo, Rochester, Syracuse, Schenectady, Troy; Albany, and Oswego are provided with direct railroad connections. All State-owned terminals are open to the public on equal terms. Lake-port terminals are extensive in character. Available terminals appear ample to meet all requirements. Operations and results during fiscal year. Costs of $270,058 reported for partial reimbursement to State of New York for work performed are set forth in Table 2-C at the end of this chapter. Government costs incurred were $18,867 for new work. Condition at end of fiscal year. Work under existing project began September 1935 and is physically complete. Forty-one barge canal bridges and three guard gates were raised to project clearance, one bridge lengthened, two bridges removed, and four guard gates replaced under Federal project for improvement. Project vertical clearance was provided at two additional bridges with Federal funds by construction of additional spillway capacity at Herkimer, N.Y. Eleven bridges were removed and replaced with new structures at project clearance with the Federal contribution limited to the estimated cost for theoretical raising the existing structure to project 84 NEW YORK, N.Y., DISTRICT clearance. Six additional bridges and one arch beam were raised, seven bridges removed and seven bridges removed and replaced by new structures at project clearance, all by other agencies.

Removed 55,644 cubic yards, place measurement, of material at a cost of $156,264 including $17,836 for engineering preliminary to dredging for maintenance. Reconnaissance surveys cost $3,643. Condition at end of fiscal year. Work under entire existing project is about 82 percent complete. Work under active portion of existing project commenced March 1932 and was completed May 1933. Upper 0.5 mile of the channel was relocated by city of New York in 1941. Head of navigation is at East Tremont Avenue, Bronx, about 2.6 miles above the mouth. Work remaining under existing project consists of dredging to 12 feet below mean low water a turning basin 250 by 250 feet in extent to be 500 feet downstream from head of navigation. Total cost of active portion of existing project to June 30, 1970, was $1,148,077 of which $98,751 was for new work and $1, 049,326 for maintenance. 23. SUPERVISION OF NEW YORK HARBOR (Prevention of Obstructive and Injurious Deposits) The Supervisor of New York Harbor is charged under Federal Statutes with the mission of preventing obstructive or injurious deposits in New York Harbor and its adjacent or tributary waters, including Long Island Sound, and the prevention of anchorage in entrance channels of the Harbor to promote safe navigation of deep-draft vessels. Federal laws enforced by the Supervisor of New York Harbor to accomplish his mission are; Act of 29 June 1888 (25 Stat. 209), as amended by Section 3, River and Harbor Act of August 1894 (28 Stat. 360), Section 8, River and Harbor Act of 28 May 1908 (35 Stat. 424), Act of 16 February 1909 (35 Stat. 623), and Act of 12 July 1952 (66 Stat. 5596); Section 2, River and Harbor Act of 18 August 1894 (28 Stat. 360), as amended 28 August 1958 (72 Stat. 970); Act of 3 March 1899 (Refuse Act, 30 Stat. 1152); Act of 7 June 1924 (Oil Pollution Act, 43 Stat. 604), as amended by the Clean Water Restoration Act of 1966, (PL 89-753), and Act of 30 August 1961 (Oil Pollution Act, 75 Stat. 402), as amended by Dept. of Transportation Act (PL 89-670; 80 Stat. 931). The waters under the jurisdiction of the Supervisor of New York Harbor include New York Harbor and its tributaries, Raritan River, Arthur Kill, Newark Bay, Hackensack and Passaic Rivers, Kill Van Kull, Hudson River and its tidal tributaries to the Federal Lock and Dam at Troy, New York, the East River and its tributaries, Harlem River and Long Island Sound. The area encompasses approximately 700 miles of waterways, 1,600 miles of waterfront and 1,500 square miles of water surface area. Patrol vessels are used to accomplish waterways inspections. Two vessels maintain 24-hour, 7-day weekly patrols; one in the Lower Bay, and the other in Long Island Sound, to inspect vessels carrying dredged or other types of waste S 95 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 material that is to be deposited in dumping grounds established by the Supervisor of New York Harbor. These vessels also patrol the entrance channels to keep them clear of interference by fishing craft or other boats in order to ensure safe navigation of deep-draft vessels. One other vessel patrols the inner waters, such as Hudson River, East River, Kill Van Kull, Arthur Kill, Passaic and Hackensack Rivers, on an 8-hour a day basis, 5 days a week, to prevent the illegal deposit of cellar dirt, ashes, industrial waste, oil or any other refuse into the navigable waters or on the beach or shore areas where it may be subject to tidal action and become a hazard to navigation. Inspections of shorefront facilities, such as industrial plants, oil refineries and shipyards are conducted 8 hours a day, 5 days a week by Inspectors utilizing Government vehicles equipped with two way radios to ensure that industrial waste or refuse is not being discharged into the navigable waters. These Inspectors operate out of various field offices located at Caven Point, New Jersey, Fort Totten in Bayside, New York, Fort Tilden at Rockaway, New York, and offices in Kingston and Troy, New York. An aggressive educational program has been maintained to inform the public of anti-pollution laws. During FY 1970 the program consisted of posting weatherproof warning signs at appropriate locations along the waterfront; distribution of Special Notices (containing extracts of pertinent Federal Statutes) to marinas, yacht clubs and the shipbuilding industry; issuance of press releases; talks before civic organizations and several radio and television interviews concerning pollution of the U.S. navigable waters. (See Table 2-F for statement of activities.) 24. RECONNAISSANCE AND CONDITION SURVEYS (See Table 2-G at end of chapter.) 25. OTHER AUTHORIZED NAVIGATION PROJECTS (See Table 2-H at end of chapter.) 26. NAVIGATION WORK UNDER SPECIAL AUTHORIZATION Navigation activities pursuant to section 107, Public Law 86-645 (preauthorization.) Fiscal year costs for preauthorization studies were $677 to complete studies of Catskill Creek, Catskill, N.Y.; $11,319 to continue studies on Cumberland Bay, Lake Champlain (Plattsburg Harbor), N.Y. initiated in FY 1967; $1,580 to start and complete reconnaissance report on Dead Horse Bay, N.Y. $8,303 to start study on Lake Champlain (Sandbar) Vt., $388 to continue study on Larchmont Harbor, N.Y. $1,192 to submit Detailed Project Report on Patchogue River (& Great South Bay), N.Y. initiated in FY 1968; and $6,136 to continue Valcour Harbor, Lake Champlain, N.Y. started in FY 1967. ALTERATION OF BRIDGES 27. STATEN ISLAND RAPID TRANSIT RAILWAY CO. BRIDGE ACROSS ARTHUR KILL, N. Y. Location. Crosses Arthur Kill, New York and New Jersey Channels about 1.5 miles south of Newark Bay and connects Elizabeth, N.J., with Staten Island, N.Y. (See Coast and Geodetic Survey Chart 369.) Existing project. A new railroad bridge to replace single track swing bridge completed in 1888. Center pier and fender system of existing bridge result in inadequate horizontal clearances which present a serious obstruction and hazard to navigation. New bridge provides a vertical lift span with vertical clearances of 135 feet above mean high water in open position and 31 feet above mean high water in closed position. New bridge eliminates center pier and leaves a clear and unobstructed channel 500 feet wide. Center of new span is about 158 feet east of center of existing bridge. Notice to alter existing bridge was signed by Secretary of the Army onJuly 5, 1949, as authorized by Truman-Hobbs Act of June 21, 1940, as amended. Estimated Federal share of cost of new work is $7,995, 000 (July 1969). Estimated cost to local interests is $1, 635,000. Local cooperation. Fully complied with. Operation and results during fiscal year. Work by legal counsel of the Railway Company in connection with outstanding claims continued. There were no Federal costs. Condition at end of fiscalyear. Project was operationally completed, first train crossed new bridge August 1959. Construction under contract No. 1 for substructure was completed August 1958. Construction under contract No. 2 for superstructure was completed December 1959. Work under terminated contract No. 3 and subsequent new contract, for demolition of structures and construction of fender system was completed in August 1962. Work remaining consists of resolution of several claims, final payments and credits. BEACH EROSION CONTROL 28. FIRE ISLAND INLET, LONG ISLAND, N.Y. Location. Atlantic Coast of Long Island, N.Y., between Fire Island Inlet and Jones Inlet, about 15 miles. Fire Island Inlet is on south shore of Long Island, about 50 miles by water south and east of the Battery, New York City, and connects Great South Bay and the Atlantic Ocean. Jones Inlet is on south shore of Long Island, about 37 miles by water south and east of the Battery, New York City, and connects Hempstead Bay 96 NEW YORK, N.Y., DISTRICT and the Atlantic Ocean. (See Coast and Geodetic Survey Charts 578 and 579.) Existing project. Provides for Federal participation in restoration and protection of shore from Fire Island to Jones Inlets by dredging inlet shoal in Fire Island Inlet and construction of a sand dike to relieve pressure of tidal currents against Oak Beach, to provide a deposition area for littoral drift, and to obtain fill material for a feeder beach and Oak Beach. Authorization initially provided for three dredging operations over a period of 10 years, but was reduced to two, based on subsequently authorized project modification for sand bypassing facilities and on limited reduction of channel maintenance costs of navigation project. For first increment, based on cost sharing provisions of Public Law 727, 79th Congress, pertinent to beach erosion control benefits, Federal participation is authorized to extent of one-third of costs allocated to beach erosion control feature and entire cost allocated to navigation feature, a total of 42 percent for first increment. In accordance with authorizing document, Federal shares of subsequent increments would be based on the then current estimates of maintenance costs which can be justified for navigation project and experience with maintenance requirements. Based on provisions of 1962 River and Harbor Act enacted after completion of first increment, which modified Federal participation to extent of one-half of costs allocated to beach erosion control feature, and on deletion of navigation benefits based on maintenance experience, Federal share of second increment was evaluated at 67.9 percent. Project, as modified, provides for combined beach erosion control and navigation improvements comprising a 1,000-foot extension of existing jetty, a littoral reservoir with a capacity of 1,200,000 cubic yards west of jetty, a navigation channel 28 feet deep and 500 feet wide leading from the littoral reservoir to a deposition reservoir inside the inlet with a capacity of 2 million cubic yards, and other appurtenant works including jetty modifications to permit fishermen use, and dikes. Estimated Federal share of participation is 66.1 percent of the first cost of project modification. Periodic transfer of littoral drift involving the bypassing of 1,200,000 cubic yards of sand on the average of once every 2 years to a feeder beach over the economic life of the project, serving both maintenance of navigation channel and nourishment of beaches westerly of the inlet, is included in annual maintenance. Project is also known as "Fire Island Inlet to Jones Inlet, N.Y." Mean range of tide is 4.1 feet. Total estimated Federal cost of new work is $16, 586,767 (July 1970), of which $2,646,767 is for work authorized by 1958 River and Harbor Act (H. Doc. 411, 84th Cong., 2d sess.), and $13,940,000 for modification authorized by 1962 River and Harbor Act (in accordance with plans in H. Doc. 115, 89th Cong., 1st sess. as approved by the Secretary of the Army and the President on February 20, 1965). Project documents contain latest published maps. Local cooperation. River and Harbor Act of 1958 provides local interests obtain approval by Chief of Engineers, before starting work on any feature of project, of detailed plans and specifications and arrangements for prosecuting work on that feature; provide lands, and rights-of-way; hold the United States free from damages; assure that water pollution that would endanger health of bathers will not be permitted; assure maintenance of recommended project during its useful life as may be required to insure realization of anticipated benefits; and assure continued public ownership of the shore and its administration for public use during economic life of project. Long Island State Park Commission of State of New York, the cooperating agency, entered into an agreement with United States August 21, 1958, as modified November 18, 1959, and February 1, 1962, in which the agency adopted plan of improvement for beach erosion control authorized by Congress and agreed to furnish its share of cost, and comply with all other requirements of local cooperation. By letter dated October 7, 1958, cooperating agency requested United States to undertake and supervise construction of first increment of work. First modification to agreement enabled construction by Federal Government of a sand closure across gorge channel which was completed in 1960 at a cost of $364,000 from funds furnished by cooperating agency (contributed funds-other). Second modification enabled delineation of sand closure as a part of authorized project in accordance with Public Works Appropriation Act, 1962, which included $152, 880 (42 percent of $364,000) specifically for repayment of Federal share of cost. Necessary adjustments of financial records to reflect revised allocation of costs was completed fiscal year 1962, and return of unused contributed funds, surplus to needs of first increment, was made May 17, 1962. Second dredging operation was financially complete April 30, 1966, and return of unused required contributed funds, surplus to needs of this increment, was made by check in June 1966 and transmitted July 7, 1966. In addition to assurances similar to those cited for the work under the 1958 act, local interests, for the work under the 1962 act, must provide and maintain a parking lot with adequate sanitary facilities as may be required for recreational fishermen use of the jetty extension; and contribute about 33.9 percent of total first cost, 32.1 percent of periodic dredging cost allocated to beach erosion control for beach nourishment, and 9.8 percent of maintenance cost. First cost includes costs, shared equally between Federal and non-Federal interests, for structural modifications to jetty extension to permit fishermen use; with maintenance of these modifications to be a Federal responsibility. Off-project fishing facilities would be a non-Federal responsibility. Total estimated cost of local cooperation to be provided by local interests is $9,443,835 (July 1970) for new work, of 97 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 which $2,272,835 (cash contribution) is for work authorized by the 1958 act; and $7,173,000 the 1962 act, of which $7,160,000 is cash contribution and $13, 000 is other non-Federal costs for off-project facilities; exclusive of shares of annual periodic dredging and maintenance costs. Operations and results during fiscal year. Utilizing appropriations for planning of work authorized by the 1962 Act, advance engineering and design continued with the completion of the model test report by the Waterways Experiment Station. Draft Design Memorandum was completed. Coordination was continued with representatives of Federal agencies and State and Suffolk County officials. Costs for advance engineering and design were $91,147, all Federal for new work. Condition at end of fiscal year. Under the 1958 Act, the first dredging operation is complete at a cost of $1,124, 826 exclusive of $1,553,331 required contributed funds. Second dredging operation is complete at a cost of $1, 521,941, exclusive of $719,504 required contributed funds. Advance engineering and design for work under the 1962 act initiated in April 1965 is about 83 percent complete. 29. OTHER AUTHORIZED BEACH EROSION CONTROL PROJECTS (See Table 2-I at end of chapter.) FLOOD CONTROL 30. BENNINGTON, HOOSIC RIVER BASIN, VT. Location. Hoosic River rises in northwestern Massachusetts, flows generally north and northwest, crossing southwest corner of Vermont to vicinity of Eagles Bridge, N.Y., where it turns west and joins the Hudson River about 16 miles above Troy, N.Y. It is 66 miles long and has a drainage area of 713 square miles. Bennington, Vt. is at junction of Walloomsac River and Roaring Branch, about 15 miles southeast of junction of Walloomsac River with Hoosic River at North Hoosic, N.Y. (See Geological Survey map covering Bennington, Vt., quadrangle). Existing project. Provides for channel excavation, about 10,500 feet of cribwall, and levee construction along the Roaring Branch extending from about 2,000 feet below the Brooklyn Bridge to about 3,500 feet above, with a concrete diversion structure at the head of a canal. Existing project was authorized by 1936 Flood Control Act and modified by 1941 Flood Control Act (H.Doc. 182, 76th Cong., 1st sess., contains latest published map). The project, previously placed in "inactive" category due to its apparently limited interest on the part of local interests in supporting construction, was reclassified to the "deferred for restudy" category January 18, 1965, based on the reported gradual erosion of left bank of Roaring Branch which local interests believe constitutes a serious threat of flooding. Based on the findings of the "restudy" (feasibility study report) initiated in December 1965 and completed in March 1966, the portion of the project on the left bank of the Roaring Branch, generally between Branch and Park Streets, was reclassified from the "deferred" to the "active" category on May 27, 1966. The improvement provides for construction of about 272 feet of floodwall, 3,437 feet of levee and appurtenant drainage facilities. The estimated Federal cost for new work is $700,000 (July 1970), exclusive of land and other work to be provided by local interests estimated at $37,000. The remaining portion of the authorized project consisting mainly of channel clearing and construction of concrete cribwalls along Roaring Branch, at an estimated Federal cost of $1,840,000 (July 1964) and estimated non-Federal cost of $30,000 for lands and other work to be provided by local interests was reclassified from the "deferred" to the "inactive" category on May 27, 1966. Local cooperation. In addition to the usual requirements for local cooperation as provided by law, local interests must give assurances that they will insure against future encroachments upon the flood channels to be provided by the improvements. Assurances of local cooperation were executed by the chairman of the Board of Selectmen, Town of Bennington, Vt. and accepted for the United States by the District Engineer on April 30 1970. Operations and results during fiscal year. Advance engineering and design and local coordination were completed on the "active" portion of the project. Acquisition by the State of Vermont of necessary lands, easements and rights-of-way was completed. A contract for $490,039 for the active portion was awarded May 27, 1970. Costs for new work were $64, 973 for design engineering. Condition at end of fiscal year. Design was completed and contract awarded. 31. EAST ROCKAWAY INLET TO ROCKAWAY INLET & JAMAICA BAY, N.Y. Location. Atlantic coast of New York City, between East Rockaway and Rockaway Inlets, and the lands within and surrounding Jamaica Bay. The coastal area (about 10 miles long) is a peninsula in Queens County separating the ocean and the bay. (See Coast and Geodetic Survey Charts 70, 369, 542, 579, 1000, 1108, and 1215.) Existing project. The multi-purpose improvement provides for a hurricane barrier, 4,530 feet long, across entrance to Jamaica Bay with a 600-foot navigation opening and two 150-foot gates which would partially close the opening to 300 feet; dikes and levees, 1.2 miles long to high ground north from the barrier and dikes, levees, and floodwalls, 7.7 miles long, south and east from the barrier to and along the'oceanfront to high 98 NEW YORK, N.Y., DISTRICT ground at eastern end of Rockaway peninsula; fill placement along the 6-mile oceanfront floodwall with a berm 100 to 200 feet wide at 10.0 feet above mean sea level; and stoplog structures, stairways, ramps, road raising, and other appurtenant works, including fishing platforms on hurricane barrier. Project includes Federal participation in cost of periodic beach nourishment of the shore protection works for 10 years after completion of the initial beach fill, the Federal share presently estimated at 50 percent of such cost. Project was authorized by 1965 Flood Control Act (see H. Doc. 215, 89th Cong., 1st sess., for latest published map). Estimated Federal cost is $43,220,000 for construction (which represents 68 percent of total first cost of project reduced by amount of local cash contribution presently estimated at $4,520,000 for the barrier, its gates and fishing platforms, equivalent to the present worth of the annual cost of maintenance, operation, and major replacements by the United States), and $318,000 annually for periodic nourishment for 10 years, a total of $46,400,000 (July 1970). Maintenance, operation and major replacements of the barrier, its gates and fishing platforms would be a Federal responsibility. Estimated non-Federal cost is $26,980,000 (representing 32 percent of total first cost of project) consisting of $160, 000 for lands and alterations and relocations of structures, and a cash contribution of $26,820,000; an additional cash contribution of $4,520,000 for the barrier, its gates and fishing platforms; and $434,000 annually for periodic nourishment for first 10-year period; a total of $31,320,000 exlusive of annual maintenance and operation costs for the project (except the barrier, its gates and fishing platforms), and of the annual cost of periodic nourishment after the initial 10 year period. Local cooperation. Local interests must provide lands and rights-of-way, including borrow areas; alter and relocate buildings, streets, storm drains, utilities, and other structures; bear 32.0 percent of total first cost presently estimated at $26,980,000, consisting of $160, 000 for items listed above, and a cash contribution of $26,820,000, the final apportionment of cost to be made after actual costs and values have been determined; provide an additional cash contribution for the barrier, its gates and fishing platforms, equivalent to the present worth of the annual cost of maintenance, operation, and major replacements by the United States, presently estimated at $4,520,000 subject to adjustment based on detailed design of project features, to be paid in a lump sum before starting construction; hold the United States free from damages; maintain, during economic life of project, continued public ownership and use of non-Federal publicly owned shores upon which Federal participation in beach protection is based; maintain and operate all works after completion, except the barrier, its gates, and fishing platforms, and provide periodic nourishment during the economic life of the hurricane and shore protection works, as may be required to serve the intended purpose, subject to Federal participation in cost of periodic nourishment of shore protection works for an initial period of 10 years; control water pollution to the extent necessary to safeguard the health of bathers; and at least annually inform interests affected that hurricane improvements will not provide substantial protection against hurricane and storm tide levels higher than about 3 feet above the elevation of Hurricane Donna of September 12, 1960. State of New York Water Resources Commission stated that the State would cooperate in meeting requirements subject to final development of a soundly engineered and economically feasible plan and cooperation from local municipalities. Operations and results during fiscal year. Advance engineering and design continued. Model testing completed, and results reviewed on January 15, 1970. Design of levees and walls, underway. Costs for advance engineering and design were $200,030, all Federal. Condition at end of fiscal year. Advance engineering and design was initiated inJanuary 1967, and is 74 percent complete.

Total estimated non-Federal cost for all requirements of local cooperation excluding maintenance is $5,000,000, inclusive of $230,000 cash contribution by local interests. Local cooperation. Local interests must provide lands and rights-of-way for construction, the costs and values incurred in the interest of hurricane tidal flood protection to be credited to required local contribution to the project first costs allocated to hurricane tidal flood protection; hold the United States free from damages; maintain and operate completed works 99 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 including all dredging required in the channel to maintain the design depths in the tidal reach; reconstruct all bridges and approaches except railroad bridges, and relocate existing sewerage and drainage facilities, streets, utilities, and other structures, such costs and values incurred in interest of hurricane tidal flood protection to be credited to required local contribution to protect first costs allocated to hurricane tidal flood protection; bear 30 percent of first costs allocated to hurricane tidal flood protection, including the two items listed above pertaining to lands, reconstruction and alterations, and a cash contribution presently estimated at $230,000, to be paid either in a lump sum before starting construction, or in installments before starting pertinent work items in accordance with construction schedules as required by the Chief of Engineers; take necessary action to protect channels from future obstruction or encroachment including waste disposal that would reduce their floodcarrying capacity; take appropriate measures to control development in partially protected areas and fringe areas not included in the project with a view to preventing an undue increase in the flood damage potential; maintain existing natural detention areas along the Elizabeth River between Union Avenue and Trotters Lane free from encroachment so as not to reduce their detention capacity; provide any additional gravity outlets or pumping station capacities made necessary by any modifications or encroachments on the ponding areas; bear any increased Federal costs for the improvement that may result from any future requirements for parkway developments; and at least annually, notify interests affected that the improvements will not provide complete protection from fluvial floods greater than that in July 1897. Agency responsible for local cooperation is city of Elizabeth (with concurrence of Union County and State of New Jersey). Signed assurances of local cooperation were accepted by the District Engineer on January 9, 1970. Operation and results during fiscal year. Design engineering continued. Design memorandum was submitted August 13, 1969 and returned with comments on May 14, 1970. Geophysical investigations and real estate studies by contract were completed. Planning was suspended January 8, 1970. Costs for design were $22,825, all Federal. Condition at end offiscalyear. Advance engineering and design began in January 1966. Design memorandum was submitted, but had to be revised. Planning is about 50% complete. Completion of engineering and design, and construction remain. 33. FIRE ISLAND INLET TO MONTAUK POINT, N.Y. Location. That portion of Atlantic Coast of Long Island extending from Fire Island Inlet easterly to Montauk Point, N.Y. Its frontage, which lies entirely in Suffolk County, is about 83 miles long and comprises about 70 percent of total ocean frontage of Long Island. Fire Island Inlet is about 50 miles by water east of the Battery, New York City. (See Coast and Geodetic Survey Charts 362, 578, 1212 and 1214.) Existing project. Provides for Federal participation in improvement to prevent beach erosion and hurricane damages along Atlantic Coast of Long Island, N.Y., from Fire Island Inlet to Montauk Point by; widening beaches along developed areas between Kismet and Mecox Bay to a minimum width of 100 feet at elevation 14 feet above mean sea level; raising dunes to an elevation of 16 feet above mean sea level from Fire Island Inlet to Hither Hills State Park, at Montauk and opposite Lake Montauk Harbor; planting grass on dunes; constructing gated interior drainage structures at Mecox Bay, Sagaponack Lake, and Georgica Pond; constructing not to exceed 50 groins, if needed; and Federal participation in cost of beach nourishment for not to exceed 10 years from year of completion of a useful nourishment unit. Total estimated Federal cost is $42,720,000 (July 1970) which includes participation in periodic beach nourishment for 10 years at $44,000 annually. Total estimated non-Federal cost for all requirements of local cooperation is $42,750,000 (July 1970), inclusive of $35,140,000 cash contribution by local interests. Project cost estimate reflects revised cost sharing provisions of 1962 River and Harbor Act, which modified Federal participation to extent of onehalf of costs allocated to beach erosion control feature, in lieu of one-third authorized by Public Law 727, 79th Congress. Evaluation resulted in increase in Federal participation from about 51 percent as originally contemplated, to about 53 percent of first cost of project construction, exclusive of annual nourishment costs. Existing project was adopted by 1960 River and Harbor Act (H. Doc. 425, 86th Cong., 2d sess.). Latest published map is in project document. Local cooperation. River and Harbor Act of 1960 provides that before starting construction, local interests give assurances they will (a) provide lands, rights-of-way, including borrow areas, for construction; (b) make alterations and relocations of buildings, streets, storm drains, utiltities, and other structures made necessary by construction; (c) bear 47 percent of total first cost, estimated at $38,070,000, to consist of items listed in (a) and (b) above and a cash contribution estimated at $35,140,000, or, if any section is undertaken separately apportionment of first cost will be as shown in District Engineer's report, with due regard to change in public use and ownership and other changes before construction; provided that cash contribution be paid either in a lump sum before starting entire project, or in installments before starting pertinent items, in accordance with construction schedules as required by Chief of Engineers, final apportionment of cost to be made after actual costs and values have been determined; (d) hold the United States free from damages; (e) maintain all works and 100 NEW YORK, N.Y., DISTRICT undertake periodic beach nourishment after completion, except that for 10 years after completion of a useful nourishment unit Federal Government would contribute, dependent on conditions of public use and ownership and other changes at time of construction an amount for entire project now estimated at $44,000 annually; (f) maintain during economic life of project continued public ownership of non-Federal publicly owned shores and continued availability for public use of privately owned shore equivalent to that upon which recommended Federal participation is based; (g) adopt appropriate ordinances to provide for preservation of dunes and their protective vegetation; (h) control water pollution to extent necessary to safeguard health of bathers; (i) obtain approval of Chief of Engineers of detailed plans and specifications for work contemplated and arrangements for its prosecution before starting any work on beach protection phase of project for which Federal participation is planned, if undertaken separately from recommended combined project; and (j) contribute in cash toward cost of hurricane protection works constructed under this plan, in addition to apportionment required in (c) above, an amount equal to increased Federal cost resulting from separate construction of beach protection work referred to in (i) above. Responsible agency is State of New York. On July 30, 1963, the State reflecting the desires of Suffolk County, requested the inclusion of a minimum of 13 groins in initial construction of Moriches-Shinnecock reach. Chief of Engineers concurred in inclusion of up to 13 groins. Assurances were executed by Superintendent of Public Works, State of New York, on August 14 and accepted by the District Engineer August 20, 1963. On February 5, 1964, the State requested consideration of a plan, as proposed by Suffolk County, for initial construction of 13 groins of which 11 would be in the Moriches- Shinnecock reach, and 2 in the Southampton-Beach Hampton reach in vicinity of Georgica Pond; and that sandfill and dune construction be withheld for the present except for 1 mile on each side of Shinnecock Inlet. On February 27, 1964, the Chief of Engineers accepted the proposals, in part, and supplemental assurances were executed by State of New York on April 20, 1964, and accepted by District Engineer April 27, 1964, as follows; the State of New York now elects to proceed with authorized combined beach erosion control and hurricane protection project for South Shore of Long Island; that Superintendent of Public Works hereby reaffirms his assurance of August 14, 1963, relative to complete project; that State of New York, as cooperating agency, will now agree that artificial fills will be added when and to extent found necessary by the Chief of Engineers, but not earlier than 3 years after completion of groins unless both the State of New York and the Chief of Engineers mutually agree to an earlier placement; that the superintendant agrees for State of New York to contribute the full amount of any increase in Federal costs resulting from the separate construction of the groins and subsequent fill; and that the State agree that construction of the two groins in the Georgica Pond area will depend on a favorable finding, following a study by the Chief of Engineers. Study was completed July 31, 1964, recommending construction, and approved by the Chief of Engineers on September 22, 1964. By letter dated November 5, 1964, the New York State Department of Public Works confirmed that title to all properties and interests in properties necessary for constructing the 11 groins was fully vested in Suffolk County. By letter dated December 7, 1964, the Department stated that the county had obtained easements or fee title for the parcels necessary for constructing the two groins. New York State Department of Public Works furnished $844,600 and $830,330 required contributed funds October 30, 1964, and September 7, 1965, respectively, for construction of 11 groins in Moriches-Shinnecock reach, and $439,900 on January 22, 1965, for construction of 2 groins in Georgica Pond area of the Southampton-Beach Hampton reach.

On March 22, 1965, the Department recommended that planning priority be in the order; Southampton- Beach Hampton (drainage structures first); Shinnecock Inlet-Southampton; Beach Hampton- Montauk Point; and Fire Island Inlet-Moriches Inlet. Planning on the drainage structures was initiated but was suspended, based on meeting of October 28, 1965 with the Georgica Pond Association and the Preservation Society of East End wherein concern was indicated regarding the effects of the proposed drainage structure on ecology, salinity, pond level and aesthetic values; based on meeting with Congressional representatives, State legislators, Federal agencies and local officials held on May 26, 1966; and based on resolution of the Suffolk County Board of Supervisors adopted June 13, 1966 requesting advancement of the planning of the Fire Island Inlet-Moriches Inlet reach (Fire Island National Seashore). On June 16, 1967, the New York State Department of Public Works requested that the following work be undertaken as immediate priority items; in Moriches-Shinnecock Reach, beach and dune fill at 11 groins site, construction of four groins west of the completed 11 groins, beach and dune fill east of the 11 groins; in Southampton-Beach Hampton reach (at East Hampton), construction of two additional groins, and the outlet structure at Georgica Pond. On March 18, 1968 the Suffolk County Board of Supervisors adopted a resolution supporting construction of 4 groins in Reach 2 (Moriches - Shinnecock) and 2 groins in Reach 4 (Southampton - Beach Hampton). On April 22, 1968 the Board adopted a more inclusive resolution authorizing participation in beach erosion and hurricane protection for the Moriches-Shinnecock 101 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 reach and in the Georgica Pond area of the Southampton-Beach Hampton reach. On December 24, 1968, the Commissioner of the New York State Conservation Department executed the second supplement to the assurances of local cooperation, which were accepted by the District Engineer on January 24, 1969. These assurances reaffirmed the previous assurances of the Department of Public Works and contain provisions for the construction of four additional groins in an area extending 6,000 feet west from the most westerly groin in the existing elevengroin field in the Moriches Inlet to Shinnecock Inlet Reach, and for placement of beach and dune fill in this four groin area to the full design cross section as defined in the authorized project report, except for the portion of the dune between mean sea level elevation 16 feet and 20 feet, thus in this stage construction establishing the top of dune to an elevation of 16 feet m.s.l. with a 65 foot width at that elevation and the top of berm to 14 feet m.s.l. with a 100 foot width at that elevation. These assurances also require that the State will obtain and provide without cost to the United States all lands, easements, and rights-of-way, which will permit entry on the lands for the period of construction, and that the necessary rights will be obtained, as required, of lands, easements and rights-of-way, for maintenance and repair of the groins, dunes, and berms, and to insure the integrity of the completed structure. Operations and results during fiscal year. Coordination with State and local interests continued.

Area included under this project comprises about 21 miles of coast in Middlesex and Monmouth Counties, N.J., and is about 30 miles southwest of New York City. It extends along Raritan and Sandy Hook Bays between entrances to Raritan River on the west and Shrewsbury River on the east. Sandy Hook, N.J., a low-lying peninsula on the east, separates Atlantic Ocean from Sandy Hook Bay. (See Coast and Geodetic Survey Charts 70, 286, 369, 375,824, 1000, 1108, 1215; and Geological Survey quadrangles of South Amboy, Keyport and Sandy Hook.) Existing project. Federal participation in constructing levees, beach fill, interior drainage facilities and groins to serve dual purposes of beach erosion control and hurricane protection. For Madison Township section, combined shore and hurricane protection improvement provides for; about 1.7 miles of beach fill at elevations of 5.5, 10, and 15 feet above mean sea level; about 0.4 mile of tieback levees at 15 feet above mean sea level; and interior drainage facilities. Shore protection improvement is provided for Matawan Township and Borough of Union Beach sections, including about 0.9 mile of beach fill at elevations of 5.5 and 10 feet above mean sea level for Matawan, and about 0.6 mile of beach fill at 5.5 feet above mean sea level for Union Beach. In the Borough of Keansburg, East Keansburg, and West Keansburg, hurricane protection is provided, including about 2.7 miles of beach fill and 2.3 miles of tieback levees at an elevation of 15 feet above mean sea level; interior drainage structures; and three groins in Keansburg for shore protection. Design studies of the Keansburg-East Keansburg section include modification of the closure by relocating the previously proposed Way Cake Creek levee to an alignment west of Thorne Creek in order to avoid poor foundation conditions. These design changes, which were incorporated into the project 104 NEW YORK, N.Y., DISTRICT plans, provide protection to an additional area in West Keansburg. Authorization also provides local interests be reimbursed $57,000 as Federal share of costs incurred by them for accomplishing beach protection at Keansburg in 1957. Total estimated Federal cost is $7,790,000 (July 1970) which includes $57,000 reimbursement to local interests. Total estimated non- Federal cost for all requirements of local cooperation is $4,210,000, including $3,673,000 cash contribution. Project cost estimate reflects the cost sharing provisions of 1962 River and Harbor Act, which modified Federal participation to extent of one-half of costs allocated to beach erosion control feature, in lieu of one-third previously authorized by Public Law 727, 79th Congress. These new provisions resulted in increase in Federal participation from about 64.8 percent to about 66.4 percent of estimated project cost exclusive of reimbursable completed work at Keansburg. Existing project was authorized in 1962 Flood Control Act (H. Doc. 464, 87th Cong., 2d sess.). Latest published map is in project document. Local cooperation. Flood Control Act of 1962 requires local interests; (a) Provide lands and rights-of-way, including borrow areas, for construction; (b) alter and relocate buildings, streets, storm drain, utilities and other structures; (c) bear percentage of total first cost for each segment (as shown in table 1, page 3, H. Doc. 464, 87th Cong., 2d sess.), to consist of items in (a) and (b) above and a cash contribution to be paid either in a lump sum before starting construction or in installments before starting pertinent items, in accordance with construction schedules as required by Chief of Engineers, final apportionment of cost to be made after actual costs and values are determined; (d) hold the United States free from damages; (e) maintain all works after completion; (f) maintain during economic life of project continued public ownership of non-Federal publicly owned shores and continued availability for public use of privately owned shore equivalent to that upon which recommended Federal participation is based; (g) control water pollution to extent necessary to safeguard health of bathers; (h) obtain approval of Chief of Engineers of detailed plans and specifications for work contemplated and arrangements for its prosecution before starting any work on recommended beach protection phase of project at Matawan Township and Borough of Union Beach or beach protection phase of project at Madison Township for which Federal participation is planned, if undertaken separately from recommended combined improvement; (i) construct, concurrently with recommended beach fill, suitable parking fields and bathhouses open to all on equal terms; and (j) at least annually inform interests affected that hurricane improvements will not provide substantial protection from bay surges higher in elevation than that of Hurricane Donna, September 12, 1960. Cost apportionment prescribed by (c) above was revised by 1962 River and Harbor Act pertinent to beach erosion control benefits, resulting non-Federal share being 33.6 percent of estimated project cost exclusive of $57,000 Federal reimbursement. Agency responsible for local cooperation is State of New Jersey. Assurances executed by State of New Jersey were accepted for the United States by the District Engineer on April 11, 1963. Supplemental assurances adding nondiscrimination clauses were executed by the Commissioner of the Department of Conservation and Economic Development of the State of New Jersey on June 7, 1968, and accepted by the District Engineer on June 19, 1968.

EMERGENCY FLOOD CONTROL ACTIVITIES - REPAIR, FLOOD FIGHTING, AND RESCUE WORK PUBLIC LAW 99, 84 TH CONG., AND ANTECEDENT LEGISLATION Under advance preparations for flood emergencies, three Supplements to ER 500-1-1 "Emergency Employment of Army Resources" were revised. One other, Supplement D "Radiological Recovery Activities" was revised and retitled "National Emergency Activities Plan" in accordance with ER 500-2-1. National Emergency Activities Plans were also prepared for the Albany and Caven Point Field Offices. The District's plan for combatting major oil spills was incorporated as an Appendix to Supplement B of ER 500-1-1. The Emergency Operations Planner attended FWPCA meetings at Edison, N.J. and Governors Island, New York, and OEP-OCD meetings in New York, New Jersey and Maynard, Massachusetts. Final inspections and post flood report were completed for the "Major Disaster" flood of May 1968 in seven northern New Jersey counties. Of the 72 local emergency repair projects considered, 60 qualified under Public Law 875. Final inspections were completed on the latter and the total reimbursement recommended to these communities by the Corps of Engineers amounted to $753,190. At the request of Governor Cahill of New Jersey, the District conducted, in May and June 1970, a survey of northern New Jersey problem areas where damages from future floods could be alleviated by a program of snagging and clearing affected secondary and tributary streams. Of the 178 communities investigated, 142 were found to have such problems. The District survey indicated that the cost of the work at these 142 localities would amount to an estimated $4,324,700. Under emergency rehabilitation, engineering for the proposed rehabilitation of the existing levee on West Canada Creek at Herkimer, N.Y., continued.

C.; the two collecting conduits, part of Dalecarlia receiving reservoir, and booster pumping plant that lifts water from forebay to main body of Dalecarlia reservoir and Little Falls raw-water supply works are in Maryland; and all other structures of water supply system including part of raw-water collecting system, purification plants, pumping stations, storage reservoirs, and transmission mains are in the District of Columbia (See U. S. Geological quadrangle, Washington and Vicinity). Control of the water supply system is vested in Chief of Engineers (See acts of March 3, 1859, and March 2, 1867, and Sec. 1800 of Revised Statutes). Existing Project. Provides for Administration, Operation, Maintenance, and protection of watersupply system facilities and reservations including collection, purification, pumping, transmission, storage facilities, and Federal Water mains; and planning and construction of increased supply facilities (See Annual Report for 1962 for authorization). Public Law 378, 64th Congress, of March 3, 1917; Public Law 119, 69th Congress, approved April 14, 1926; and Public Law 118, 80th Congress, June 26, 1947, authorized supplying water to adjacent Maryland areas, Arlington County, Virginia, and Falls Church, Virginia, respectively. For description of District of Columbia water supply system and of previous capital-improvement and 177 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 operation-and-maintenance projects see Annual Report for 1930, information pamphlet published June 1939 and revised December 1950, and House Document 480, 79th Congress, 2nd Session. Local cooperation. Prior to July 1, 1880, expenses of Washington Aqueduct for construction, operation, and maintenance were paid wholly out of revenues of the United States. From July 1, 1880, to June 30, 1882, expenses of operation and maintenance were paid onehalf by the United States and the other half out of general revenues of the District of Columbia. From July 1, 1882, to June 30, 1898, one-half of construction costs were charged to a capital account on the books of the Treasury to be repaid by the District of Columbia from water rents with 3 percent interest. From July 1, 1898, to June 30, 1916, expenses of construction, operation, and maintenance were paid one-half from surplus general revenues of the District of Columbia and one-half from the United States Treasury. From July 1, 1916, to June 30, 1927, expenses of construction were paid 60 percent out of general revenues of the District of Columbia and 40 percent by the United States. From July 1, 1927, to date, all expenses for construction have been paid out of water revenues of the District of Columbia. From July 1, 1916, to date, expenses of operation and maintenance have been paid wholly out of water revenues of the District of Columbia. From April 1953, to June 30, 1970, $29,300, 000 was borrowed from the United States Treasury, in installments, to finance expansion and improvement of the District of Columbia water system as authorized by Public Law 533, 81st Congress, 2nd Session, of June 2, 1950, as amended by Public Law 364, 83rd Congress, 2nd Session, of May 18, 1954. Public Law 280, 66th Congress, 2nd Session, of June 10, 1920, appropriated $25,000 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. This "Tyler" report was the basis for improvements constructed from 1922 to 1927. Included in the District of Columbia appropriation acts of 1941 and 1942, $40,000 was appropriated from the water fund, District of Columbia, for preparation of a report "for the development of a plan to insure an adequate future water supply for the District of Columbia." This report, published as House Document 480, 79th Congress, 2nd Session, contains comprehensive plan and program for improvements and additions to the water system. Annually, since July 1, 1920, on a percentage basis and, since July 1, 1924, on a lump-sum basis, the United States has contributed to support of the District of Columbia but, prior to July 1, 1947, no part of such annual percentage or lump-sum contribution has been allocated to the water fund, District of Columbia. From fiscal year 1948 through June 30, 1954, pursuant to Public Law 195, 80th Congress, 1st Session, an annual $1,000,000 was authorized for water consumed by the Federal Government. Public Law 364, 83rd Congress, 2nd Session, which is known as the "District of Columbia Public Works Act of 1954," provided payment by the United States for all water and water services furnished, and increased authority for borrowing. Public Law 533, 81st Congress, 2nd Session, authorized the Secretary of the Treasury to lend, with a limit of $23,000,000, to the Commissioners of the District of Columbia such sums as may hereafter be appropriated to finance expansion and improvement of the water system when sufficient funds therefor are not available from the District of Columbia Water Fund established by law (D. C. code 1940 edition, title 1943, ch 15). Above public law was amended by Public Law 364, 83rd Congress, 2nd Session, by striking the figure "23,000,000" and inserting in lieu thereof the figures "35,000,000." Operation and Results During the Fiscal Year. An uninterrupted and adequate supply of purified water was furnished to the District of Columbia; Arlington County, and Falls Church, Va.; and Federal establishments in Arlington County, Va., and Montgomery and Prince Georges County, Md. Total consumption for the year was 70,484 million gallons; the maximum daily consumption was 277.9 million gallons and average daily consumption was 193.1 million gallons. Based on estimated average number of consumers of 954,000 in the District of Columbia and 266,000 in Arlington County and Falls Church and Fairfax County, Va., average per capita daily consumption was 158.3 gallons. Average daily consumption in the District of Columbia alone was 158.5 million gallons or an average per capita daily consumption of 166 gallons. Average daily amount of water furnished to Arlington County, Fairfax County, and Falls Church, Va., was 34.5 million gallons or an average per capita daily consumption of 130 gallons. The Water Fund, D. C., was reimbursed $1,309,410 for supply of water furnished Virginia communities. An average of 163,000 gallons per day was delivered to Maryland communities during fiscal year 1970 by the Water Division, D. C., through connections to the Washington Suburban Sanitary Commission's system. On June 23, 1952, fluoridation equipment was put in service and application of sodium silicofluoride started and continued through February 1964 when the use of Hydro-Fluosilicic acid was started. Average turbidity of raw water from the Potomac River was reduced from 72 to 0.2 parts per million or "Jackson Units." Analyses were made for coliform bacteria on 146,340 tubes of Lactose broth inoculated with water taken from 208 sampling points in the collection, purification, and distribution systems. Approximately 120,212 physical and chemical tests were made on 13,570 water samples from the supply and distribution system. After sterilization of the filter effluent, average Most Probable Number of coliform bacteria per 100 milliliters was found to be .15 at Dalecarlia and .20 at the McMillian filter plant. 178 BALTIMORE, MD., DISTRICT Average calcium carbonate alkalinity of the filtered water was 65 P.P.M. and the average pH value was 7.8 from Dalecarlia filter plant, and 60 and 7.9 respectively, from McMillan filter plant. Average hardness was 125 P.P.M. from Dalecarlia and 121 P.P.M. from McMillan. Flourine content of 4,270 water samples was determined. In fiscal year 1970, direct operating cost of water treated and delivered to system per million gallons was $56.80 as compared with cost of $52.15 per million gallons in fiscal year 1969. Visitors. During the year 1,104 persons were conducted through water treatment and pumping plants and bacteriological and chemical laboratories of which 1,095 were engineering and science students, public school pupils, civic groups, and public officials, 9 foreign visitors. Control. All funds were expended in conformity with the legislative provision contained in the annual appropriation act which is as follows; "Nothing herein shall be construed as affecting the superintendence and control of the Secretary of the Army over the Washington Aqueduct, its rights appurtenances, and fixtures connected with the same, and over appropriations and expenditures therfor as now provided by law." Condition at end of fiscal year. Intakes, conduits, reservoirs, filter plants, pumping stations, mechanical equipment, and structures were in good condition generally. Deep cleaning of the filters at McMillan Reservation will be resumed when conditions warrant it. During maximum demand periods, the Little Falls raw-water pumping station was operated to augment raw-water supply of gravity-flow conduits. Construction work authorized with "no year" funds not previously reported as completed was as follows; Continuing utility relocations and system interconnections, 95 percent; repairs to roadways and landscaping, 60 percent; new shops and storehouses, Dalecarlia, 25 percent; new office facility, Dalecarlia, 100 percent; Great Falls intake structure, 99 percent; flood and water quality protection Dalecarlia 60 percent. Funds are being requested in the FY 1972 budget for planning for a rapid-sand type filter plant at McMillan. The feasibility of building a raw-water pumping station on the Potomac River estuary, to provide a limited supplementary raw-water supply until adequate fresh water storage could be provided upstream on the Potomac River has been investigated. Funds for such a project will require authorization by Congress. 179 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 COST AND FINANCIAL STATEMENT See Section Total to in Text Project Funding FY 67 FY 68 FY 69 FY 70 June 30, 1970 1.

Total cost of existing project to June 30, 1970, was $23,076, 496 of which $3,396,276 (including $1 million for purchase of Albemarle & Chesapeake Canal and Dismal Swamp Canal) was for new work, $19,200,273 for maintenance, and $479,947 for rehabilitation. Periodic maintenance dredging is being done to maintain a 12- foot controlling depth on the Albemarle and Chesapeake Canal Route and a 7- foot controlling depth on the Dismal Swamp Canal Route. 2. AQUATIC PLANT CONTROL, VA. Location. Navigable waters, tributary streams, connecting channels, and other allied waters in Norfolk District. Areas in which there are significant aquatic plant nuisance problems include Back Bay-Eurasian water milfoil; Rappahannock River-Eurasian water milfoil; City of Norfolk-sea lettuce; and Chickahominy River-elodea. Existing project. Provides for control and progressive eradication of water- hyacinth, alligatorweed, Eurasian water milfoil, and other obnoxious aquatic plant growths, from the navigable waters, tributary streams, connecting channels, and other allied waters of the United States, in the combined interest of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health, and related purposes, including continued research for development of the most effective and economic control measures, to be administered by the Chief of Engineers, under the direction of the Secretary of the Army in cooperation with other Federal and State agencies. Local cooperation. Local interests must agree to hold the United States free from damages that may occur from operations performed in connection with this project, and participate to extent of 30 percent of cost of program. Operations and results during fiscal year. Review comments of various, interested agencies, regarding the General Design Memorandum for Virginia were received. As a result of coordination meetings and correspondence, interest was indicated such that a oneseason, experimental control program is anticipated on the Walker Dam Impoundment, Chickahominy River, Virginia. However, local interests and other agencies did not indicate an interest in operational control programs for the three remaining areas where aquatic 202 NORFOLK, VA., DISTRICT plant problems exist. This reluctance was due primarily to the lack of an acceptable method of control. It was agreed that continued surveillance of the aquatic plant infestations in these areas as well as appropriate coordination would be maintained. Condition at end of fiscal year. The General Design Memorandum was approved and a one- season, experimental treatment was authorized for the Walker Dam Impoundment, Chickahominy River, Virginia. The Virginia Commission of Game and Inland Fisheries tentatively agreed to furnish the items of local cooperation required for the one- season experimental treatment. Pending receipt of the formal assurances of local cooperation, spraying operations are scheduled in late fiscal year 1971. 3. BALTIMORE HARBOR AND CHANNELS (NORFOLK DIST.)

MULTIPLE- PURPOSE PROJECTS INCLUDING POWER. 26. SALEM CHURCH LAKE, VA. Location. The Salem Church multiple purpose reservoir, to be located on the Rappahannock and Rapidan Rivers in Spotsylvania, Stafford, Orange, Culpepper, and Fauquier Counties, Va., would be created by a concrete gravity dam on the Rappahannock River 5.6 miles above Fredericksburg, Va., and 113 miles above the mouth. At maximum power pool, the lake will extend about 26 miles upstream on the Rappahannock River and 24 miles on the Rapidan River. (See Geological Survey Quadrangles "Fredericksburg," "Salem Church," "Storck," "Midland," "Richardsville," "Chancellorsville," "Remington," "Germanna Bridge," "Mine Run," "Culpepper" and "Unionville.") A reregulating dam, Fredericksburg Dam, included in the project, will be located 2.8 miles downstream from the Salem Church Dam. Previous projects. For details see page 264 of Annual Report of 1954. Existing project. The project provides for construction of Salem Church Dam, including powerhouse and Fredericksburg Dam. Salem Church Dam consists of a concrete gravity dam, approximately 1,560 feet long with a maximum height of 203 feet above river bed, and earth embankments extending from both abutments, totaling 14,000 feet in length. The spillway, located in the concrete gravity section of the dam, is controlled by 9 crest gates 50 feet by 42 feet with a discharge capacity of 608,000 cubic feet per second. The powerplant, immediately downstream of the dam, contains two conventional generating units with a total installed capacity of 89,000 kilowatts. The lake will have a total storage capacity of 1,048,000 acre- feet. At conservation pool elevation of 240 feet above mean sea level the lake will have an area of 21,000 acres. Fredericksburg Dam reregulates the power flow released from Salem Church. It consists of a concrete ungated spillway with concrete non- overflow sections, 1,115 feet long, with a maximum height of 46 feet above river bed. The total estimated (1970) initial project cost for new work, $94,900,000, includes non- Federal reimbursements of $39,600,000 for costs allocated to power, water supply and recreation and excludes an estimated (1970) $14,300,000 for the cost of future additions to recreational facilities. (See Table 5- B for authorizing legislation.) Local cooperation. Prior to construction, local interests are required to furnish assurances that they will; a. Establish encroachment lines downstream of the dams. b. Hold and save the United States free from the damages due to water rights claims resulting from construction and operation of the project. c.

Navigable waters, tributary streams, connecting channels, and other allied waters in Wilmington District. Existing project. The existing project provides for control and progressive eradication of water-hyacinth, alligatorweed, Eurasian watermilfoil, and other obnoxious aquatic plant growths from navigable waters, tributary streams, connecting channels, and other allied waters of the United States, in the combined interest of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health, and related purposes, including continued research for development of the most effective and economic control measures in cooperation with other Federal and State agencies in accordance with the report of the Chief of Engineers, House Document 251, 89th Congress, 1st session. The project was authorized by Section 302, 1965 River and Harbor Act (H. D. 251, 89th Cong., 1st sess.) The Act provides that research and planning costs shall be borne fully by the United States. Local cooperation. Local interests must agree to hold the United States free from damages that may occur from operations performed in connection with this project, and participate to the extent of 30 percent of the cost of the program. Requirements are being met. Operations and results during fiscal year. Trial field applications of granular 2,4-D were applied on a total of 200 acres of Eurasian watermilfoil in Currituck Sound in June 1968 (FY 68). The studies on the effects on water quality and marine life by the U. S. Fish and Wildlife Service have shown no adverse effects. Observations of the overall watermilfoil problem are continuing. Treatment of limited high priority high use areas and of certain area to prevent further southward spread of the weed may be recommended. Condition at end of fiscal year. The state General Design Memorandum was submitted to higher authority and approved. The supplemental agreement to contract with the State of North Carolina was finalized and has been approved and accepted by the State. 2. ATLANTIC INTRACOASTAL WATERWAY BETWEEN NORFOLK, VA AND ST JOHNS RIVER, FLA. (WILMINGTON DISTRICT) Location. The project is located on the east coast of the United States, between Norfolk, Va., and St. Johns River, Florida. The section within Wilmington District begins at the Virginia-North Carolina State line and extends generally southerly and southwestwardly to Little River, S. C. a total of 308 statute miles. (See Coast and Geodetic Survey Charts 830 to 842, inclusive.) Previous projects. For details see Annual Reports for 1915, 1926, 1932, and 1938. Existing project. The authorized project provides for a waterway, 12 feet deep, with widths varying from 90 feet in land cuts to 300 feet in open waters; the construction, operation and maintenance of suitable bridges; salt-water-intrusion preventive measures in the vicinity of Fairfield, N. C.; a channel in Peltier Creek, 6 feet deep and 50 feet wide from the Intracoastal Waterway in Bogue Sound to and including a basin in Peltier Creek, 6 feet deep, 200 feet wide, and 600 feet long; a channel, 6 feet deep and 90 feet wide between the Intracoastal Waterway and the gorge in Bogue Inlet; a channel, 12 feet deep and 90 feet wide to a turning basin, 200 feet wide and 350 feet long, at Swansboro; a channel, 6 feet deep and 90 feet wide in New River Inlet, and a connecting channel of the same dimensions to the Intracoastal Waterway near the mouth of New River; a channel, 10 feet deep 90 feet wide in New River, between the Intracoastal Waterway and the Seaboard Coast Line Railroad bridge at Jacksonville, N. C.; a channel through New Topsail Inlet, 8 feet deep and 150 feet wide and a channel from New Topsail Inlet to the Intracoastal Waterway by way of Old Topsail Creek, 7 feet deep and 80 feet wide; a channel, 7 feet deep and 80 feet wide, in Banks Channel, from New Topsail Inlet, paralleling the barrier beach, to the Atlantic Intracoastal Waterway; a channel, 14 feet deep and 400 feet wide, across the ocean bar at Masonboro Inlet, with suitable jetties at the entrance, thence 12 feet deep and 90 feet wide to the channel of the Intracoastal Waterway at Wrightsville by way of Banks and Motte Channels; a turning basin, 15 feet deep, 300 feet wide, and 700 feet long, on the east side of Banks Channel near Masonboro Inlet, with three 15-pile dolphins therein; a channel, 6 feet deep, 80 feet wide, and 8,000 feet long, to and including a turning basin of the same depth, 130 feet wide and 180 feet long, at Carolina Beach; a yacht basin, 230 feet wide, 450 feet long, and 12 feet deep, at the town of Southport, connected to the waterway by a suitable channel of the same depth; and maintenance of the general navigation features of the North Carolina State Ports Authority Small-Boat Harbor at Southport, consisting of an entrance channel, 150 feet wide and 400 feet long, an eastern harbor-access channel, 70 feet wide and 430 feet long, a western harbor-access channel, 60 feet wide and 185 feet long, to a turning basin, 180 feet wide and 550 feet long, all to a depth of 6 feet. Length of channels and 226 WILMINGTON, N.C., DISTRICT basins totals 347.1 miles. Plane of reference is mean low water. In the waterway north of Neuse River, variations in water surface due to winds seldom exceeds 2 feet above or below mean stage. Between Beaufort and the Cape Fear River, normal tidal range varies from 3-1/2 feet at the inlets to 1 foot at points between. Average range of tide is 4 feet on the ocean side of Bogue Inlet and 2.5 feet just inside the inlet. At New River, tidal range varies from 3-1/2 feet at the inlet to 1 foot at the head of the marshes and zero at Tar Landing, 31 miles above. From Cape Fear River, N. C., to Little River, S.

All other tables are referenced in text and also appear at the end of this chapter. 259 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 and wildlife conservation, public health and related purposes, including continued research for development of most effective and economic control measures in cooperation with other Federal and State agencies in accordance with report of Chief of Engineers. The act provides that research and planning cost shall be borne fully by the United States. (See Table at End of Chapter for Acts Authorizing Existing Project.) Local cooperation. Local interests must agree to hold the United States free from damages that may occur from operations performed in connection with this project, and participate to extent of 30 percent of cost of program. Requirements are being met in South Carolina. Operations and results during fiscal year. New Work: Chemical control operations were continued by Corps of Engineers personnel in the Little Pee Dee River, Black River, Black Mingo Creek, North Fork Edisto River and Congaree River basins. Colonies of Flea Beatles (Agasicles) established for the biological control of alligatorweed at Foster Creek near Charleston, at Halfway Swamp on Lake Marion and in the Edisto and Ashepoo River basins were very active during September 1969. Monitoring operations at those release sites during June 1970 revealed very little activity although the existence of the beatles was still apparent. Condition at end of fiscal year. Chemical spraying operations have been made on approximately 750 acres of alligatorweed under effective control in the five basins cited above. Adaptation of biological agents to local climatic conditions should result in additional acreage being brought under control. The state design memorandum has been updated and approved. 3. ATLANTIC INTRACOASTAL WATERWAY BETWEEN NORFOLK, VA., AND ST. JOHNS RIVER, FLA. (CHARLESTON DISTRICT) Location. The project is on Little River near the North and South Carolina State line and extends generally south along the coast of South Carolina 62 miles to Winyah Bay; thence 63.5 miles to Charleston; thence 84.5 miles to and including Port Royal Sound; a total of 210 miles.

Federal costs under the existing project to date have been $3,328,349 for new work and $28,975,316 for maintenance, a total of $32,303,665. 5. COOPER RIVER, CHARLESTON HARBOR, S.C. (ST. STEPHEN PROJECT) Location. Cooper River is located in Charleston and Berkeley Counties, S.C., and empties into the Atlantic Ocean at Charleston. Existing project. The major cause of the shoaling problem in Charleston Harbor is the diversion of fresh water from the Santee River through Pinopolis Dam into the salt water of Charleston Harbor, causing density currents which trap sediments resulting in a phenomenal rate of deposition. The most practical and economical solution of the shoaling problem is to redivert most of the Santee River waters above Pinopolis Dam into the lower Santee River through a canal beginning at Lake Moultrie and extending to the Santee River in the vicinity of St. Stephen, South Carolina. The existing project for Cooper River as authorized by the River and Harbor Act (See Table at End of Chapter for Acts Authorizing Existing Projects) provides that the discharge through the existing Pinopolis Hydro Plant be reduced to an average of 3, 000 cubic feet per second. This flow would not establish a density current in the harbor. The excess water then impounded in Lake Moultrie would be directed through a new canal above St. Stephen, South Carolina, to enter the Santee River at a point well below the Lake Marion Spillway (Wilson Dam). A new hydroelectric facility would be constructed on the new canal where the ground elevations decrease to become swampland adjacent to the Santee River. This plant would replace those features made ineffective at Pinopolis through curtailment of flows. The power production flow of 24,500 cfs at the new powerplant, plus the proposed 3,000 cfs average release planned for Pinopolis, would approximate the existing total Pinopolis flow capacity. The three generators at the new plant would be rated at 28,000 kilowatts each, for a total of 84,000 kilowatts. In the interest of fish and wildlife resources of the area, the plan would also provide for construction of a herring lift at the new powerhouse site and a relocated fish hatchery, if found necessary; and a gated structure on the South Santee River for control of salinity in the delta reaches. Local cooperation None needed. The gated structure on South Santee, originally thought to be subject to local cooperation is for the purpose of migratory waterfowl which is a federally sponsored program. Operations and results during fiscal year. During FY 70 early implementation studies were completed and a report was written. Authority for this study was by OCE using O&M funds. Advance Engineering and Design Studies were initiated after funds were released in April 1969 and studies continued in FY 70-target date for 6 Design Memorandum is 1 July 1970. Condition at end of fiscal year. The project is currently in the advanced planning stage. 6. GEORGETOWN HARBOR, S.C. Location.

The state contributed 30 per cent of cost of the project and agreed during the 10-year period following initial construction to contribute, prior to the periodic nourishment work, 30 per cent of the cost thereof. Operations and results during fiscal year. Beach profiles were taken. Condition at end of fiscal year. Beach profiles taken during FY 70 indicated that upwards of 260,000 cubic yards of the beach fill placed in December 1968 had been lost. It is planned to renourish the beach with 750,000 cubic yards of sand during the spring of 1971. 16. BEACH EROSION CONTROL UNDER SPECIAL AUTHORIZATION ACTIVITIES PURSUANT TO SECTION 103, PUBLIC LAW 87-874 (PREAUTHORIZATION) None. FLOOD CONTROL 17. YADKIN RIVER, N.C. Location. The river rises on the eastern slope of the Blue Ridge Mountain in western North Carolina, flows generally easterly 100 miles to vicinity of Dannaha, N.C., thence southeasterly 104 miles to its confluence with Uwharrie River near Badin, N.C., where its name changes to Great Pee Dee River. (See U.S. Geological survey map of North Carolina.) Existing project. The Flood Control Act of July 24, 1946, authorized construction of four flood-control dams in the upper Yadkin River Basin, two on the Yadkin River above Wilkesboro, N.C., and two on Reddies River, a tributary stream. Studies made subsequent to authorization established the economic advantage of providing needed flood-control storage in only two reservoirs, one on the Reddies and one on the 263 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Yadkin. Present planning considers only the tworeservoir plan. Cost for the Yadkin River Reservoir (W. Kerr Scott Dam and Reservoir constructed 1962) and for Reddies River Lake is set forth in Table 7-D. (See Table at End of Chapter for Acts Authorizing Existing Project.) Funds of $131,500 have been expended on the Reddies River Lake Project for project planning and preparation of a definite project report which was completed in March 1950. An economic restudy of the Reddies River Lake Project was submitted and approved in July 1968. Individual reports on W. Kerr Scott Dam and Reservoir and Reddies River Lake Project follow. 17A. W. KERR SCOTT DAM AND RESERVOIR, YADKIN RIVER, N.C. Location. W. Kerr Scott Dam and Reservoir is on Yadkin River, N.C., about 6 miles upstream from Wilkesboro. At full flood-control pool elevation (1075 feet mean sea level), the reservoir extends 15.7 miles upstream to Wilkes-Caldwell County line. Existing project. The project consists of a rolled earthfill dam 1,740 feet long, with crest at elevation 1, 107.5 feet mean sea level, or about 148 feet above streambed elevation; a spillway near the north abutment of the dam in a rock cut with crest elevation 1075; and outlet works consisting of an intake structure, control tower, and a circular concrete conduit 12.25 feet in diameter through the base of the dam near the south abutment. The reservoir has a gross capacity of 153,000 acre-feet of which 112,000 acre-feet are reserved for flood control, 33,000 acre-feet will be used when required for water supply, and 8,000 acrefeet being contained in the minimum pool. (See Table at End of Chapter for Acts Authorizing Existing Project.) Local cooperation. Fully complied with. For details see page 413 of Annual Report for 1963. Operations and results during fiscal year. New Work: Construction of recreation facilities at completed project (Code 710) cost $133,151. Maintenance: Operation and maintenance cost $248,204. During the fiscal year the project had a visitation of 546,759. All recreation facilities continue to be utilized beyond their maximum capabilities during fair weather. Acquisition of additional lands and construction of recreational facilities authorized under the Appalachia Program has resulted in the project having the capability to accommodate approximately 250,000 additional visitors annually. The majority of visitor requirements continues to be for camping and picnicing facilities. On three occasions the watershed area received excessive amounts of rainfall, resulting in the necessity to control the outflow to prevent possible flood damages to the areas below the dam. All outlet works facilities performed efficiently with a minimum amount of time required for control operation. Condition at end of fiscal year. The project was commenced in August 1960 and placed in operation for flood control and water storage purposes in February 1963. 17B. REDDIES RIVER LAKE, N.C. Location. The Reddies River flows into the Yadkin River near the town of North Wilkesboro, N.C., and is a tributary to the Yadkin-Pee Dee River. The authorized lake and damsite are located entirely in Wilkes County, North Carolina. Existing project. Reddies River Lake is the second unit in the authorized plan for the upper Yadkin River Basin. The first unit, W. Kerr Scott Reservoir, is located about 5 miles upstream from the mouth of the Reddies River and was completed in 1962. The Reddies damsite is located on Reddies River at mile 1.7, near the town of North Wilkesboro. Total tributary area above the damsite is 94.5 square miles. Project works contemplate construction of a rolled-earth dam about 165 feet high with a saddle spillway and a gated outlet conduit. The conservation pool will cover about 720 acres and the flood control pool about 1,383 acres. The project was authorized by the Flood Control Act of 1946; however, the project was deferred for restudy in 1950. An economic restudy was submitted in FY 69 and approved in FY 70. AE&D funds were appropriated in FY 70, but, the funds were held in budgetary reserve throughout FY 70. (See Table at End of Chapter for Acts Authorizing Existing Project.) Local cooperation. The state of N.C. has given letters of intent to fulfill the local cooperation requirements necessary for water supply and development of recreational facilities. Operations and results during fiscal year. The economic restudy referred to above was submitted to higher authority by Charleston District during the fiscal year as were post authorization charges. Condition at end of fiscal year. Construction funds for AE&D have been appropriated. Studies are underway. 18. BUCK CREEK, N.C. & S.C. Location.

ALTAMAHA, OCONEE, AND OCMULGEE RIVERS, GA. Location. These rivers are entirely within the State of Georgia. (See U. S. Geological Survey map of Georgia.) For full description of these rivers, see page 636, Annual Report for 1932. Previous projects. Prior projects for the Altamaha River had been adopted, and expenditures made under them, by River and Harbor Acts of March 3, 1881, and September 19, 1890; for the Oconee River by River and Harbor Acts of June 18, 1878, September 19, 1890, and March 3, 1905; for the Ocmulgee River, by River and Harbor Acts of August 14, 1876, and September 19, 1890. For further details, see page 1815, Annual Report for 1915, and page 589, Annual Report for 1938. Existing project. The authorized project provides for an appropriation of $40,000 annually for the Altamaha, Oconee, and Ocmulgee Rivers, to maintain a 3-foot depth during ordinary summer low water and to gradually increase channel depth, so far as practicable without sacrificing the maintenance work. This project covers the entire Altamaha River (including a channel between the river and Darien, Ga.), a length of 137 miles, the lower 145 miles of the Oconee River, and the lower 205 miles of the Ocmulgee River. The Altamaha River has a mean tidal range of 6.4 feet at its mouth which gradually decreases to mile 33 above, where there is no perceptible tidal effect. At Doctortown, mile 59, ordinary floods attain a height of about 10 feet above low water, and extreme floods, a height of about 15 feet above low water. On the Oconee River at Dublin the ordinary fluctuations attain a height of 22 feet, and the extreme fluctuations a height of 32 feet, above low water. On the Ocmulgee River at Macon the ordinary fluctuations attain a height of 15 feet, and the extreme fluctuations a height of 25 feet, above low water. There is no approved estimated cost for improvement or for maintenance. The existing project was adopted by River and Harbor Acts of July 25, 1912 (H. D. 443, 62d Cong., 2d sess.), and March 2, 1945 (H. D. 610, 77th Cong., 2d * All cost and financial statements for projects are listed at the end of this chapter. All other tables are referenced in text and also appear at the end of this chapter. 275 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 sess.). The latest published maps of these rivers are in the following documents: Altamaha River, House Executive Document 283, Fifty-first Congress, second session; Oconee River, House Executive Document 211, Fifty-first Congress, first session; Ocmulgee River, House Executive Document 215, Fifty-first Congress, first session; and Lower Altamaha River and Darien Harbor, Ga., House Document 610, Seventy-seventh Congress, second session. Local cooperation. Fully complied with. Terminal facilities. Along these rivers there are numerous natural shore landings which are considered ample for existing commerce. Facilities for recreational boats have been constructed in recent years at several points. Operations and results during fiscal year. Maintenance: On November 17 hired labor snagging work was initiated by crane barge No. 2 with towboat Piasa and the snagging was completed on March 20, 1970 at a cost of $52,909 including inspection and overhead. Other costs incurred, including hired labor, hydrographic surveys, mapping of the rivers, and water pollution studies, amounted to $46,555. Condition at end of fiscal year. The existing project is such that the percentage of completion cannot be stated. Channel depths have been increased by excavating rock shoals and sandbars, by constructing contraction and bank-protection works, and by closing cutoffs. Navigation has been rendered safer by removing obstructions. Many of the closing dams and contractions and bank-protection works need repairs. During the year: The Altamaha River had a controlling depth of 3 feet or greater 65 percent of the time; the Oconee River from the Forks to Dublin, Ga., had a controlling depth of 2.5 feet or greater 65 percent of the time; and the Ocmulgee River from the Forks to Abbeville, Ga., had a controlling depth of 3 feet or greater 70 percent of the time. Low water usually occurs between August and December. Controlling depths were then one-half to 1 foot less than those given above. To June 30, 1970, costs under the existing project were $60,847 for new work and $1,425,257 for maintenance, of which $13,533 were contributed funds, a total of $1,486,104. 2. AQUATIC PLANT CONTROL (RIVER AND HARBOR ACT OF 1965) Location. Navigable waters, tributary streams, connecting channels, and other allied waters in Savannah District. Existing project. The project provides for control and progressive eradication of water-hyacinth, alligatorweed, Eurasian water milfoil, and other obnoxious aquatic plant growths, from navigable waters, tributary streams, connecting channels, and other allied waters of the United States, in the combined interests of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health, and related purposes, including continued research for development of most effective and economic control measures in cooperation with other Federal and State agencies in accordance with report of Chief of Engineers, House Document 251, 89th Congress, 1st session. The project was authorized by section 302, of the 1965 River and Harbor Act (H. D. 251, 89th Cong., 1st sess.). The act provides that research and planning costs shall be borne fully by the United States. Local cooperation. Local interests must agree to hold the United States free from damages that may occur from operations performed in connection with this project and participate to the extent of 30 percent of the cost of the program. Requirements are being met. Operations and results during fiscal year. The General Design Memorandum for the State of Georgia, entitled "Planning for Comprehensive Program for Aquatic Plant Control" was updated. 3. ATLANTIC INTRACOASTAL WATERWAY BETWEEN NORFOLK, VA., AND THE ST. JOHNS RIVER, FLA. (SAVANNAH DISTRICT) Location. This 161 mile section of waterway connects Port Royal Sound, S. C., with Cumberland Sound, Ga. and Fla. (See Coast and Geodetic Survey Charts 838- 841, inclusive.) Previous projects. (Between Savannah, Ga., and Fernandina, Fla.) For details see Annual Reports for 1915 and 1938. Existing project. The project provides for a waterway 12 feet deep at mean low water and not less than 90 feet wide between Port Royal Sound, S.C., and Savannah, Ga.; 12 feet deep at mean low water, with widths of 90 feet in landcuts and narrow streams and 150 feet in open waters, between Savannah, Ga., and Cumberland Sound, Ga. and Fla.; and a suitable anchorage basin at Thunderbolt, Georgia. Mean tidal range between Port Royal, S. C., and Cumberland Sound, Ga. and Fla., is from 6 to 8 feet, with fluctuations from 1 1/2 to 2 1/2 feet, due to winds and lunar phases. (See table 8-B for Authorizing Legislation.) Local cooperation. Fully complied with. Terminal facilities. Exclusive of adequate terminal facilities at ports of entry, this improvement serves numerous wharves, some of which are open to the public on equal terms. Facilities are considered ample for existing commerce. Operations and results during fiscal year. Maintenance: A lump sum contract was awarded June 17, 1969 for maintenance dredging. The pipeline dredge Cherokee removed 487,758 cubic yards of material from the main route of the waterway at South River, Little Mud River, North River, Doboy Sound, Hell Gate, Wilmington River, and Elba Island Cut, at a total cost of $165,974. A combined contract for Atlantic Intracoastal Waterway and Brunswick Harbor was awarded May 28, 1970, and work was initiated June 15, 1970 for maintenance dredging. The contract 276 SAVANNAH, GA., DISTRICT pipeline dredge Cherokee removed 167,770 cubic yards of material from the main route of the waterway at Creighton Narrows and South River during the period June 15 to June 30, 1970 at a cost of $72,480. Construction of spoil dikes was performed by Government plant and hired labor during the fiscal year at a cost of $2,368. Project condition surveys, condition studies, water pollution studies, and other Government cost amounted to $64,568. Condition at end of fiscal year. The main channel of the existing project, completed in 1941, is maintained at 12 feet. Along the main route, a minimum depth of 11 feet was recorded in St. Augustine Creek, Wilmington River, Hell Gate, and Bear River. The former main channel, now an alternate route through the westerly end of the South Channel and northerly end of Wilmington River, will be maintained to a depth of 7 feet mean low water for traffic points north and south of Savannah Harbor. Costs of the existing completed project to June 30, 1970, were $763,599 for new work and $7,104,601 for maintenance, a total of $7,868,200. 4. BRUNSWICK HARBOR, GA. Location. The Harbor entrance is 70 statute miles south of the entrance to Savannah Harbor, Ga., and 25 statute miles north of the entrance to Fernandina Harbor, Florida. (See Coast and Geodetic Survey Chart 447.) Previous projects. For details see Annual Reports for 1915 and 1938. Existing project. The project provides for a stone jetty 4,350 feet long at the entrance to East River and the following channels: 32 feet deep and 500 feet wide across the bar; 30 feet deep and 400 feet wide through St. Simon Sound, Brunswick River, and East River to the foot of Second Avenue; 30 feet deep and 300 feet wide in Turtle River to the Allied Chemical Co. wharf, formerly the Atlantic Refining Co.; 27 feet deep and 350 feet wide in East River from Second Avenue to its confluence with Academy Creek; 24 feet deep and 150 feet wide in Academy Creek; and a cut from Academy Creek to Turtle River, if decided advisable; a channel in Back River 20 feet deep and 150 feet wide from St. Simon Sound to the mouth of Mill Creek; and a channel in Terry Creek 10 feet deep and 80 feet wide from its mouth to a point immediately above the wharf of Glynn Canning Company. All depths refer to mean low water. Mean tidal range on the bar is 6.5 feet, at the city of Brunswick 7.3 feet, and 7.6 feet at the upper end of the harbor. The existing project was authorized by six River and Harbor Acts between 1879 and 1950. In general, the current project is covered by the 1950 River and Harbor Act (H. D. 110, 81st Cong., 1st sess.). For further details see Annual Report for 1962. Local cooperation. Complied with to date. Terminal facilities. Twenty-six wharves and piers, almost all privately owned, have a berthing space of 11, 4444 feet. In addition, the Port of Brunswick and the State of Georgia constructed a transit shed and modern docks with 1,500 feet of aprons on East River at a cost of over $1,300,000. For further details see Port Series No. 16, Corps of Engineers (revised 1954). Operations and results during fiscalyear. Maintenance: A combined contract was awarded June 13, 1969 for maintenance dredging of East River, construction of a closure dam in East River, and construction of spoil dikes on Andrews Island. Work was initiated July 8, 1969 and completed November 12, 1969. Construction of the closure dam and spoil dikes cost $329,317 and $390,000, respectively; maintenance dredging by the contract dredge Arlington removed 295,068 cubic yards of material in East River at a cost of $88,840, for a total contract cost of $808,157. A combined contract for the Atlantic Intracoastal Waterway and Brunswick Harbor was awarded May 28, 1970 for maintenance dredging of Brunswick Harbor. The U. S. hopper dredge Hyde dredged October 14 to November 12, 1969 and removed 127,970 cubic yards of material from the bar channel at a cost of $140,619. The U. S. hopper dredge Gerig dredged May 22 to June 18, 1970 and removed 415,723 cubic yards from the bar channel at a cost of $259,473. Costs for existing completed project to June 30, 1970 were $12,073,993, of which $3,433,743 was for new work and $8,640,250 for maintenance. Routine condition surveys, water and air pollution studies, Government supervision and administration, engineering and design, and engineering investigations in connection with model studies cost $72,399. Condition at end of fiscal year. The existing project was completed in December 1960. General condition of the harbor works is satisfactory, providing maintenance dredging continues. Minimum readings of authorized project depths were: In 32-foot channel, 30 feet on St. Simon Range; in 30-foot channel, 28 feet on Brunswick Cut Point Range; in 27-foot channel, 17 feet above Second Avenue. Costs for existing completed project to June 30, 1970, were $12,060,393, of which $3,420,143 was for new work and $8,640,250 for maintenance. 5. SAVANNAH HARBOR, GA. Location. Harbor entrance is 75 statute miles south of Charleston Harbor, S.C., and 70 statute miles north of Brunswick Harbor, Ga. (See Coast and Geodetic Survey Chart 440.) Previous projects. For details see Annual Reports for 1915 and 1938. Existing project. The project provides for a channel 40 feet deep and 600 feet wide across the ocean bar about 7.0 miles; 38 feet deep and 500 feet wide to the Seaboard Coast Line terminal; 38 feet deep and 400 feet wide to the vicinity of Garden City (Georgia Ports Authority terminal); and 36 feet deep and 400 feet wide to the vicinity of Savannah Sugar Refining Corp., about 22.6 miles; and 30 feet deep and 200 feet wide to 277 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 a point 1,500 feet below the Atlantic Coastal highway bridge, about 1.5 miles, a total length of 31.1 miles; three turning basins 34 feet deep by 900 feet wide by 1, 000 feet long in the vicinity of the Seaboard Coast Line terminal, American Oil Company terminal, and Garden City terminal of the Georgia Ports Authority; two turning basins 30 feet deep by 600 feet wide by 600 feet long near Savannah Sugar Refining Corporation terminal and at the extreme upper limit of the project near Continental Can Company terminal. The project also provides for sediment control works consisting of a tide gate structure across Back River; a sediment basin 40 feet deep, 600 feet wide, about 2 miles long, with an entrance channel 38 to 40 feet deep and 300 feet wide; a drainage canal across Argyle Island 15 feet deep and 300 feet wide; control works and canals for supplying fresh water to the Savannah National Wildlife Refuge; and facilities to mitigate damages to presently improved areas other than refuge lands. Mean range of tide is 7.8 feet at the upper end of the harbor and 6.9 feet at the lower end. Extreme ranges are about 11.1 and 10.7 feet, respectively. The existing project was authorized by 14 River and Harbor Acts from 1907 through 1965. In general, the River and Harbor Act of 1965 covers the principal features of the existing project. Latest approved estimate of total Federal Cost for new work modification (approved May 1970) is $18,002,000 ($9,672,000 for the Widening and Deepening of Channels and Turning Basin which includes $192,000 U. S. Coast Guard costs, and $8,330, 000 for the Sediment Basin and Appurtenant Works). Estimated local cost for Widening and Deepening is $367,000 and for the Sediment Control Works is $455, 000. Local cooperation. Local interests must provide suitable spoil areas and retaining dikes for construction and future maintenance of the project. The Chatham County Commissioners, as local assurers, have met all requirements to date. Terminal facilities. Fifty piers and wharves adequately serve existing waterborne commerce of the port. These facilities, with use of dolphins, have a combined berthing space of 28,400 feet with water depths alongside ranging up to 34 feet at mean low water. All have railway and highway connections. For further details, see Port Series No. 14, Corps of Engineers (revised 1954) and Annual Report for 1962. Operations and results during fiscal year. New work: Engineering and design of authorized modifications continued during the year. Activities in connection with the Sediment Basin and Appurtenant Works Modification included completion of Design Memorandum No. 3, Sediment Basin: Fresh Water Control Plan and Appurtenances. Plans and specifications for the Sediment Basin, Drainage Canal, and Hydraulic Fill were completed. Plans and specifications for the Tide Gate Structure and Access Road, Fresh Water Control Structures and Canals, and Fresh Water Diversion Channels are approximately 82, 77, and 7 percent complete, respectively. Plans and specifications for dredging the upper inner harbor and Marsh Island Turning Basin were completed, work advertised, and bids opened May 14, 1970; however the low bidder, Hendry Corporation; Tampa, Florida, exceeded award authority. Subsequently, the low bidder claimed an error was made in the bid which, if corrected, would be within award authority. Maintenance: The U.S. hopper dredge Gerig dredged the bar channel during April 24, 1970 to May 21, 1970 and removed 565,329 cubic yards of material at a cost of $317,928, including other government costs. The U.S. pipeline dredge Henry Bacon dredged the inner harbor during July 1 to July 17, 1969, August 4, 1969 to May 3, 1970 and June 20 to June 30, 1970 and removed 4,618,197 cubic yards of material at a cost of $1,072,430, including other government costs. The project received $47,459 from private shipping interests to reimburse the government for having to remove silt material placed by them within the project limits of the inner harbor. The material is the result of agitation dredging by private owners of slips in wharf areas in an effort to maintain adequate depths for their private docking facilities. Dragging and sweeping operations in the inner harbor cost $14,906. Maintenance of spoil dikes by Government draglines amounted to $10,737, including other costs. Condition surveys, floculation studies, water and air pollution studies, inspections and reports, and government supervision and administrative costs were $137,652. Condition at end of fiscal year. The existing project is incomplete. Training walls, jetties, and other structures are in fair condition. Authorized channels are maintained by a planned dredging program with work at critical areas when necessary. Minimum readings from depths authorized were: In 40-foot channel, 36 feet at Tybee Knoll; in 38-foot channel, 32 feet at City Front and Marsh Island; in 36-foot channel, 24 feet at Port Wentworth. Costs of existing project to June 30, 1970, were $12,537,780 for new work and $45,457,573 for maintenance, a total of $57,995,353. 6. SAVANNAH RIVER BELOW AUGUSTA, GA. Location. Savannah River is formed by the confluence of the Tugaloo and Seneca Rivers on the boundary line between South Carolina and Georgia. It flows southeast 314 miles, forming the boundary line between the two states, and empties into the Atlantic Ocean 16.6 miles below Savannah, Ga. (See Geological Survey maps of South Carolina and Georgia.) Previous project. For details see Annual Reports for 1915 and 1938. Existing project. The authorized project provides for a channel 9 feet deep and 90 feet wide (at ordinary summer flow of 5,800 second-feet at Augusta, Ga.) from the upper end of Savannah Harbor to the head of navigation at Augusta, 3 miles above Fifth Street 278 SAVANNAH, GA., DISTRICT Bridge, a total distance of about 199 miles. Improvement is to be obtained by construction of contraction works, closure of cutoffs, bank protection, dredging, removal of snags, overhanging trees and wrecks, and open-river regulation. Mean tidal variation at the mouth of the river is 7 feet. Freshet variation above the normal pool level (elevation 114.5 mean sea level) of New Savannah Bluff lock and dam at mile 203 is ordinarily about 13 feet with an extreme of 34 feet. Latest approved project cost estimate for providing a 9-foot channel (Sept. 1963) is $6,576,000 exclusive of amounts expended on previous projects. Recreation facilities at New Savannah Bluff lock and dam cost $17,000. Existing project was authorized by seven River and Harbor Acts between 1890 and 1950 and is generally as authorized by 1950 River and Harbor Act (S. D. 6, 81st Cong., 1st sess.). For further details see Annual Report for 1962. Local cooperation. Complied with to date. The City Council of Augusta, Ga., and the Georgia and South Carolina Ports Authorities have agreed to act as local assurer. Terminal facilities. The only water terminals served by this improvement are at Augusta, Sylvania, and at or near Savannah. Augusta provided a municipal dock valued at $50,000 and Georgia Ports Authority constructed a State port at Augusta, Ga., costing about $418,000. These facilities were expanded in 1965 at an additional cost of about $250,000. In addition, Pure Oil Co., Texaco, Inc., and Merry Brothers Brick and Tile Co. maintain terminals below Augusta, and Allied Chemical Co. maintains terminal at Sylvania. These are supplemented by natural landings along river and extensive facilities at Savannah. Operations and results during fiscal year. Maintenance: The contract pipeline dredge Ideal removed 238,835 cubic yards of material during fiscal year at cost of $205,173, including government costs. A continuing contract for construction of bank revetments was awarded April 23, 1970 for $86,947. Costs generated to end of fiscal year for this contract amounted to $12,749, including Government costs. A maintenance pipeline dredging contract was awarded in the latter part of the fiscal year, June 26, 1970, in the amount of $72,100. Expenditures incurred for this work consisted of Government costs for plans and specifications, etc., which amounted to $8,512. The U. S. crane barge No. 2 with towboat Piasa accomplished five months of snagging at a cost of $53,039 from July 1, 1969 through September 5, 1969 and March 25, 1970 through June 30, 1970. Routine operation of the Lock and Dam, including water and air pollution studies, inspections and reports, and government supervision and administration cost $82,506. Other Government cost amounted to $7,920. Condition at end of fiscal year. In general, open-channel works are in good condition. Project depth of 9 feet was maintained 80 percent of fiscal year, with a minimum depth of 7 feet recorded at mile 43. Costs of existing project to June 30, 1970, were $11,720,491 of which $6, 646,551 was for new work and $5,073,940 for maintenance. 7. OTHER AUTHORIZED NAVIGATION PROJECTS (See Table 8-C.)

BEACH EROSION CONTROL ACTIVITIES PURSUANT TO SECTION 103, PUBLIC LAW 87-874 (PREAUTHORIZATION) (See Table 9-J.) FLOOD CONTROL 34. CENTRAL AND SOUTHERN FLORIDA Location. The project is located generally within the southeastern eighteen counties of Florida covering an area of about 15,200 square miles. It is comprised of the Upper St. Johns River basin in the northeastern section of project, Kissimmee River basin in central section above the Lake Okeechobee-Everglades area in the central and southwestern section, and the east coast Everglades area in southeastern section. Previous projects. Completed works for control of Lake Okeechobee were included in and constructed under the navigation project for Okeechobee Waterway, Fla. (formerly Caloosahatchee River and Lake Okeechobee drainage areas, Fla.), and under provisions of River and Harbor Acts of July 3, 1930, and August 30, 1935. For further information, see Annual Reports, 1948 and 1949. Existing project. The project is for flood relief and water conservation and provides principally for: an east coast protective levee extending from the Homestead area north to the eastern shore of Lake Okeechobee near the St. Lucie Canal; three conservation areas for water impoundment in the Everglades area west of the east coast protective levee with control structures to effect transfer of water as necessary; local protective works along the lower east coast; encirclement of the Lake Okeechobee agricultural area by levees and canals; enlargement of portions of Miami, North New River, Hillsboro, and West Palm Beach Canals; enlargement of the existing Lake Okeechobee levees and construction of new levees on the northeast and northwest shore of the lake; increased outlet capacity for improved control of Lake Okeechobee; floodway channels in the Kissimmee River basin, with suitable control structures to prevent overdrainage; an interrelated system of canals, levees, pumping stations, and structures in southwest Dade County to control water levels; and facilities for regulating floods in the Upper St, Johns River basin; a system of canals and control structures for gravity drainage of Martin County and distribution of available water supplies to portions of Martin and St. Lucie Counties; and works to improve the supply, distribution, and conservation of water resources in central and southern Florida, including the Lake Okeechobee agricultural area, Everglades National Park, and other related areas. The project will provide water control and protection from recurrence of the devastating floodwaters from the Everglades and local sources, for the highly developed urban area along the 302 JACKSONVILLE, FLA., DISTRICT lower east coast of Florida and for the productive agricultural areas around Lake Okeechobee (including towns around lake), in the Upper St. Johns and Kissimmee River basins, and in South Dade County. The project includes a total of 1,030 miles of levees, 1,014 miles of canals, 32 pumping plants, 200 floodway control and diversion structures, and 62 railroad relocations (bridges). The project also provides that upon completion, local interests assume operation and maintenance of all completed works except levees, channels, locks, and control works for regulation of Lake Okeechobee and the main control structures of conservation areas, which will be operated and maintained by the United States. The principal features of the hurricane gates, constructed under previous projects for Okeechobee Waterway and maintained under existing project since July 1, 1950, are set forth in Table 9-K.

In addition to the actual facilities listed above it is necessary under Operation and Maintenance to continue meteorological studies, water level records, stream gaging stations, etc., for proper regulation of the level of Lake Okeechobee and storage of water in Conservation Areas 1, 2, and 3. Regulation. a. General. Fiscal Year 1970 was a wet year over most of the project area. In October and again in March rainfalls, ranging from the high of record to no lower than the 4th highest of record for those months, occurred over most of the project area. These rainfall amounts ranged from 8.3 to 13.9 inches in October and from 8.4 to 12.4 inches in March. A drought of 53 days' duration followed the March rainfall during which little or no rainfall was recorded over a large portion of the project area. A new interim water delivery schedule to the Everglades National Park was adopted in February. This schedule sets the minimum monthly amounts of water to be released to the park based on Lake Okeechobee stage and the stage on the P-33 gage located in the park. During this fiscal year the Everglades National Park received a total of 2,123,790 acre-feet of water from the project. In addition over 5.0 million acre-feet of water was released from the 4 major project storage areas to tidewater. At the end of the fiscal year all of these storage areas were slightly above their scheduled stage. b. Corps of Engineers. (1) Lake Okeechobee. Rainfall on the lake totaled 60.97 inches for the fiscal year, which was 11.09 inches above normal. The October rainfall, 9.1 inches, was the fourth highest October of record and the March rainfall, 12.4 inches, was the highest March of record. Inflow to Lake Okeechobee for the fiscal year totaled 4, 273,000 acre-feet, equivalent to 9.3 feet of storage on the lake. Of this total 1,743,000 acre-feet occurred during the months of October and March. Net water supply for the fiscal year amounted to 4,900,000 acrefeet, which was 272 percent of normal. Stages on the lake reached a peak of 16.6 feet on November 2, 1969, and 16.8 feet on April 2, 1970. On both occasions stages were returned to schedule within 30 to 35 days following the peak. Emergency closure of Hurricane Gate No. 6 was made following the March storm to reduce the health hazard to the city of Okeechobee caused by overflowing septic tanks and drainfields. The landside stage was reduced from 16.6 feet to 15.0 feet and held for 24 days by Pumping Station No. 133 until the lake could be returned to a safe level. This action 303 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 was made possible due to the drought that followed the March rains, as S-133 was pumping a drainage area much larger than it was designed for. Regulatory releases from Lake Okeechobee through the St. Lucie Canal totaled 1,837,000 acre-feet, and through the Caloosahatchee River 2,564,000 acre-feet, a total of 4, 401,000 acre-feet for the fiscal year. Additional releases of 479,000 acre-feet were made via the agricultural canals for regulatory and irrigation purposes. A new interim regulation schedule which raised the lower limits of the schedule from 13.5 feet to 14.0 feet was approved in May for use during the calendar year 1970. (2) Water Conservation Area No. 1 was above schedule more than half the fiscal year. The net water supply to the area amounted to 833,190 acre-feet. Rainfall for this period totaled 57.66 inches, which was 1.18 inches above normal. The October rainfall amount of 8.3 inches was the fourth highest of record for October and the March total of 9.8 inches was the highest March of record. In contrast, the April total of 0.3 inch was the fourth lowest of record. The peak stage reached during the fiscal year was 17.9 feet on November 4, 1969. Regulatory releases of 605,400 acre-feet were transferred to Water Conservation Area 2A through S- 10. Releases to the east, including seepage and regulatory releases to tidewater, totaled 239,710 acrefeet. (3) Water Conservation Area 2A had a net water supply of 1,430,990 acre-feet for the year. It was above schedule 9 months during the year, reaching a peak stage of 15.4 feet on November 4, 1969. In April 1970, a new interim regulation schedule was tentatively approved by higher authority which raised the lower limits of the seasonal regulation schedule from 12 to 13 feet. Rainfall over the area totaled 62.59 inches for the year, 11.75 inches above normal. The monthly rainfall total for October, 10.2 inches, and March, 9.0 inches, were near record highs for those months. Regulatory releases through S-11 to Area 3A totaled 633,120 acrefeet. Releases to the east, including seepage, irrigation and regulatory releases to tidewater totaled 448,140 acre-feet. Regulatory releases to tidewater were made during 8 months of the fiscal year to help relieve high stages in the deer area in Water Conservation Area 3A. These releases are estimated to total 285,000 acre-feet for the fiscal year. (4) Water Conservation Area 3A was above schedule all but 17 days during the fiscal year. Net water supply to the area totaled 2,516,140 acre-feet. Rainfall totaled 62.01 inches for the fiscal year, 11.58 inches above normal. The monthly total rainfalls for October, 13.9 inches, and for March, 8.4 inches, were period of record highs for those months. In contrast the April rainfall 0.06 inch was the second lowest April rainfall of record, 2.5 inches below normal. A peak average stage of 11.55 feet was reached in the area on November 1, 1969. This was 1.05 feet above the scheduled stage of 10.5 feet. A total of 2,138,790 acre-feet was discharged through the S-12 Spillway to the Everglades National Park during the fiscal year. The 24 gates in this spillway were open clear of water a total of 325 days during this period. Daily discharges ranged from a high of 4,780 c.f.s. to a low of 1,900 c.f.s. with the gates open full.

OTHER AUTHORIZED FLOOD CONTROL PROJECTS (See Table 10-I) 41. FLOOD CONTROL WORK UNDER SPECIAL AUTHORIZATION Flood Control activities pursuant to Section 205, Public Law 858, 80th Congress, as amended (Preauthorization). (See Table 10-J) Emergency flood control activities-repairf,l oodf ighting, and rescue work (Public Law 99, 84th Congress, and antecedent legislation, and disaster relief activities under Public Law 875.) (See Table 10-J) MULTIPLE PURPOSE PROJECTS INCLUDING POWER 42. ALABAMA--COOSA RIVERS, ALA. AND GA. Location. Alabama River is formed 18 miles above Montgomery, Ala., by the junction of the Coosa and Tallapoosa Rivers. It then flows southwesterly through Alabama 318 miles, and unites with the Tombigbee River about 45 miles north of Mobile, in southwestern Alabama, to form the Mobile River. (See Geological Survey maps for central and southwest Alabama.) The Coosa River is formed at Rome, Ga., in northwest Georgia, by the junction of the Oostanaula and Etowah Rivers, which have their sources in southeastern Tennessee and northern Georgia. From Rome the Coosa River flows southwesterly through Georgia and Alabama 286 miles, and unites with the Tallapoosa River near Montgomery, Ala., at about the center of the State, to form the Alabama River. (See Geological Survey maps for northeast Alabama, southeast Tennessee, and northwest Georgia.) Previous projects. Projects for Alabama River: For details see page 1837, Annual Report for 1915; page 725, Annual Report for 1938; and page 592, Annual Report for 1944. Projects for Coosa River: For details see page 1837, Annual Report for 1915; page 728, Annual Report for 1938; and page 594, Annual Report for 1944. Existing project. The authorized project provides for full development of the Alabama-Coosa Rivers and tributaries for navigation, flood control, power, recreation, and other purposes, in accordance with plans under preparation by Chief of Engineers, subject to modifications thereof which may be advisable for increasing development of hydroelectric power. "See Table 10-B for authorizing legislation." Public Law 436, 83d Congress, suspended authorization of the comprehensive plan, insofar as it provides for development of Coosa River, to permit non-Federal interests to develop the Coosa River by construction of a series of dams in accordance with conditions of a license issued pursuant to Federal Power Act and in accordance with certain other provisions and requirements of the aforementioned public law. The present phase of improvement, now under construction, provides for construction of Jones Bluff and Millers Ferry multiple-purpose improvements, Claiborne lock and dam, and supplemental channel work providing for a 9-foot deep navigation channel from the mouth of the Alabama River to Montgomery, Ala., and for construction of Carters Dam, a multiplepurpose improvement on Coosawattee River, Ga. Estimated cost 1970 for new work on Alabama-Coosa Rivers is $255,955,800 consisting of $252,035,800, for structures, and $3,920,000 for supplemental channel improvemtnts, exclusive of amounts expended on previous projects. 348 MOBILE, ALA., DISTRICT Local cooperation. Requirements of local cooperation will be determined as formulation of plans for development of projects progress. No action in the matter of local cooperation has been initiated. Terminal facilities. On the east bank of the river a natural landing connects with city streets at Montgomery. Wofford Oil Company has a small wharf about 10 miles below Montgomery equipped for handling petroleum products. There are also various natural landings along the river. Facilities and natural landings on Alabama River are considered adequate for existing commerce. Operations and results during fiscal year. New work: Construction continued on Carters Dam, Millers Ferry lock and dam, Claiborne lock and dam, and Jones Bluff lock and dam. Acquisition of land was continued on the Alabama River channel at a cost of $589. Engineering, design, supervision, and administration cost $52,798. Maintenance: Operation and care of Claiborne lock cost $29,316, and maintenance of Claiborne lock amounted to $867. The U. S. pipeline dredge Collins, worked a total of 81 1/3 days removing 887,096 cubic yards of material from the Alabama River, at a cost of $275,205. The U. S. snagboat Toro performed snagging in the Alabama River, a total of 6 days at a cost of $5,160. Miscellaneous surveys and investigations cost $44,622; and engineering, design, supervision, and administration cost $46,866. Reconnaissance and condition surveys cost $288. Coosa River reservoirs cost $18,575. Total fiscal year costs for entire project, including lock and dam projects, amounted to $23,331,673 for new work and $775,902 for maintenance. Detailed information on operations and costs applicable to the four structures is presented under their respective project titles elsewhere in this report. Condition at end offiscalyear. Construction was initiated on Carters Dam in April 1962, on Millers Ferry lock and dam in April 1963, Claiborne lock and dam in May 1965, and Jones Bluff lock and dam in March 1966. Maintenance operations on the Alabama River, since authorization of the existing project, have been limited mainly to periodic dredging to restore a 4-foot open-channel depth from the mouth of the river to Wetumpka as provided for under previous projects. Maintenance operations on the Coosa River, which were discontinued in 1950, consisted mainly of the care of Government property at locks and dams constructed under previous projects. These locks and dams have been inoperative for some years and no longer serve any useful purpose. Inspections of the lower Alabama River in 1955 indicated a controlling depth of 4 feet from the mouth to Claiborne. Boats drawing 3 feet can usually operate all year; however greater depths are usually available from November to June. Since all existing locks on the river are inoperative, through navigation on the Coosa River is impossible. (See Table 10-K for developments proposed under existing 451-584 0-72-23 project and 10-L or fiscal year costs for new work on overall project.) 42A. ALLATOONA RESERVOIR, COOSA RIVER BASIN, GA.

AQUATIC PLANT CONTROL PROGRAM Location. Lakes and streams in State of Louisiana. Existing project. Provides for control and progressive eradication of water-hyacinth, alligatorweed, and other obnoxious aquatic plant growth from navigable waters, tributary streams, connecting channels, and other allied waters in North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas, in combined interests of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health, and related purposes, including continued research for development of most effective and economic control measures. The modification of 1965 provides for comprehensive program for control and progressive eradication of water-hyacinth, alligatorweed, Eurasian water milfoil, and other obnoxious plant growths from navigable waterways, tributary streams, connecting channels, and other allied waters of the United States, in combined interest of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health, and related purposes, including continued research for development of most effective and economic control measures. Research and planning costs undertaken pursuant to 1965 act shall be borne fully by the United States and shall not be included in costs to be shared by local interests. Local cooperation. Local interests must hold the United States free from claims and participate in project to extent of 30 percent of cost of operations. State of Louisiana, Department of Public Works and Louisiana Wild Life and Fisheries Commission furnished a joint assurance of local cooperation, which was approved April 29 and accepted May 4, 1959. Under provisions of continuing contract, local agencies will perform work in kind, approximating 30 percent of cost of program. Operations and results during fiscal year. A part of Teche Basin south of U. S. Highway 190 was treated by crews of the Corps. Teche Basin feeder areas north of U. S. Highway 190 were assigned to crews of State of Louisiana under contract and they continued to reduce area of infestation. Progress continues in this basin. All principal waterways of Maurepas-Pontchartrain Basin were cleaned by combined efforts of the Corps and State of Louisiana. This combined effort continues to obtain satisfactory results in small tributaries and main waterways. Large isolated lakes and streams in northern half of State, part of which are within limits of Vicksburg District, were cleaned of most surface vegetation. Maintenance of this area is assigned to the State with occasional assistance by Corps crews in some of the lakes and streams. Satisfactory progress is being made in this area. Waterways between Atchafalaya east guide levee and Mississippi River levee south of Morganza control structure are being cleaned by a combined effort of Corps and State crews. This work is progressing with satisfactory results. A combined effort is being made in Atchafalaya Basin on several waterways that are a source of reinfestation of main navigable waterways in Atchafalaya Basin, Gulf Intracoastal Waterway, and other connecting streams by Corps and State crews. Results are progressing in a satisfactory manner. During operations 17,113 acres of vegetation were destroyed. State of Louisiana crews destroyed 9,373 acres of vegetation by chemical treatments only. Crews of the Corps destroyed 7,740 acres of vegetation using both chemical and mechanical methods. Research work to discover means to chemically destroy alligatorweed and other obnoxious aquatic plants, under contract with University of Southwestern Louisiana, continued with promising results. Condition at end of fiscal year. Operations under 1958 R&H Act initiated May 1959, are complete. Operations under 1965 R&H Act were initiated in fiscal year 1968. Waterways are being cleared, then maintained as required. 2. ATCHAFALAYA RIVER AND BAYOUS CHENE, BOEUF, AND BLACK, LA. Location. The improvement is located in the parishes of Assumption, Terrebonne, and St. Mary, La., in the vicinity of Morgan City, along Bayous Chene, Boeuf, and Black, and the Lower Atchafalaya River to the Gulf of Mexico. (See Mississippi River Commission alluvial maps, Morgan City, Belle Isle, and Point au 380 NEW ORLEANS, LA., DISTRICT Fer quadrangles, Coast and Geodetic Survey Chart 1276, and navigation maps of Intracoastal Waterway and Atchafalaya River system.) Existing project. Provides for enlargement and extension of project, Atchafalaya River, Morgan City to the Gulf of Mexico, La., to obtain navigation channels 20 feet deep over a bottom width of 400 feet from vicinity of U. S. Highway 90 crossing over Bayou Boeuf to the Gulf of Mexico via Bayou Boeuf, Gulf Intracoastal Waterway, Bayou Chene and the landside levee borrow pit drainage channel, Lower Atchafalaya River, and Atchafalaya Bay to the Gulf of Mexico, and from near U. S. Highway 90 to Bayou Chene via Bayou Black and the Gulf Intracoastal Waterway. Estimated cost for new work (July 1970) is $12,100,000 Federal and $1,190,000 non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $40,000. Local cooperation. The local agency must provide all lands, easements, and rights-of-way for construction and subsequent maintenance of the project and for aids to navigation upon the request of the Chief of Engineers, including suitable areas required in the general public interest for initial and subsequent disposal of spoil, and also necessary retaining dikes, bulkheads, and embankments therefor or the cost of such retaining works; accomplish and maintain all modifications to roads, bridges, pipelines, cables and any other utilities and improvements necessary for the construction and subsequent maintenance of the project; and hold the United States free from damages due to construction and maintenance of the project. The Board of Commissioners of the Morgan City Harbor and Terminal District, the local sponsoring agency, enthusiastically endorsed the project; however, diligent efforts since January 28, 1969, to obtain formal assurances of local cooperation from that agency have been unsuccessful. Terminal facilities. Two large and three small public wharves at Morgan City are open for use by all without charge. In addition, there are numerous privatelyowned facilities located on both banks of the lower Atchafalaya River in Morgan City and Berwick, La., and along Bayou Boeuf and the Gulf Intracoastal Waterway. Fabrication and repair facilities are located on Bayous Boeuf and Black. Adequate acreage is available for expansion of existing terminals and construction of new terminals along Bayous Chene, Boeuf, and Black, and the Gulf Intracoastal Waterway. Public and private terminals in the project area are adequately connected with rail, water and highway transportation facilities. No additional public wharves are required. Operations and results during fiscal year. Planning funds were made available late in the fiscal year. Planning was limited to review of engineering work performed by an Architect-Engineer under contract to the Morgan City Harbor and Terminal District. 451-584 0-72-25 Condition at end of fiscal year. Construction has not been initiated. 3. ATCHAFALAYA RIVER, MORGAN CITY TO GULF OF MEXICO, LA. Location. Atchafalaya River is an outlet of Red River and controlled flow from Mississippi River. It begins at mouth of Red River, about 4.5 miles west of Old River navigation lock on northern boundary of Pointe Coupee Parish, and flows generally south about 135 miles and empties into Atchafalaya Bay, an inlet of the gulf. Section under improvement is from 20-foot contour in Atchafalaya Bay, 4 miles beyond mouth of Atchafalaya River, to 20-foot contour in Gulf of Mexico. (See Coast and Geodetic Survey Chart 1276, Mississippi River Commission alluvial valley maps, Morgan City, Belle Isle, and Point au Fer quadrangles, and navigation maps of Gulf Intracoastal Waterway and Atchafalaya River system.) Existing project. A 20- by 200-foot channel from 20- foot contour in Atchafalaya Bay, to 20-foot contour in Gulf of Mexico. Project depth refers to mean low water. Normal range of tide is 10 inches; extreme range, 14 inches; hurricane range, 10 feet. The existing project, prior to the modification of August 1968, was completed at a cost of $501,963. Local cooperation. Fully complied with, except for modification of project in connection with Atchafalaya River and Bayous Chene, Boeuf, and Black, La., which is reported separately. Terminal facilities. At Morgan City there are several small private wharves and two large and three small public ones open for use of all without charge. There are no warehouses needed, as business section is on riverfront and all freight is transferred directly from boats to stores. Facilities considered adequate for existing commerce. Operations and results during fiscal year. Hired labor forces conducted shoaling studies and surveys. The contract dredge Arkansas restored 11.9 miles of channel to 16-foot depth between miles 10.5 and 22.4 below mouth of river, during period August 30 through December 21, 1969.

BAYOU LAFOURCHE AND LAFOURCHE-JUMP WATERWAY, LA. Location. Prior to 1902 Bayou Lafourche was an outlet of Mississippi River, its head being at Donaldsonville, La., 80 miles above New Orleans. It flows generally southerly 107 miles to Gulf of Mexico. (See Coast and Geodetic Survey Charts 1116 and 1274; Mississippi River Commission alluvial valley maps; Donaldsonville, White Castle, Napoleonville, Thibodaux, and Lac des Allemands quadrangles; and Geological Survey maps Houma, Cutoff, Lake Felicity, Mink Bayou, Leeville, and Belle Pass quadrangles.) Previous projects. For details see page 564 of 1963 Annual Report. Existing project. Provides for permanent closure of head of bayou without a lock, a channel 6 feet deep and 60 feet wide from Canal Boulevard in Thibodaux to Lockport, and from LaRose to Gulf of Mexico with a jettied entrance at Belle Pass, and the closure of Pass Fourchon. These improvements are about 50.5 miles long, and the modification of July 14, 1960, provides for an additional 66 miles of improvement as follows: a 12- by 125-foot channel, extending from Gulf Intracoastal Waterway at mile 37.2 west of Harvey lock to enter Bayou Lafourche below highway bridge at Leeville at about mile 12; a 12- by 125-foot channel in Bayou Lafourche from point of junction with proposed 12-by 125-foot channel to 12-foot depth contour in gulf; modification and extension of existing jetties from 6- to 12-foot contour, if found advisable to reduce maintenance dredging in the gulf; and a channel 9 by 100 feet in Bayou Lafourche from Leeville to vicinity of lower limits of Golden Meadow; and a 12- by 125-foot channel from Bayou Lafourche at Leeville from point where auxiliary channel connects with Bayou Lafourche through Southwestern Louisiana Canal to and through Bayou Rigaud to connect with enlargement of Bayou Rigaud recommended under project "Barataria Bay Waterway, La." Normal range of tide is 10 inches at mouth and 3 inches at head; from severe rains, 3 to 10 feet at head; from hurricanes, up to 10 feet at mouth. Estimated cost for new work (July 1970) is $7,320,000, Federal, and $3,120,000, non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $31,000. (Excavation of a channel 6 feet deep and 60 feet wide from Thibodaux to Gulf Intracoastal Waterway at Lockport is considered inactive and excluded from foregoing cost estimate. Estimated cost of this portion (July 1970) is $733,000. Local cooperation. Assurances received and accepted on all items of work in the project. Golden Meadow to gulf" Local agency has conveyed to the United States title to all necessary channel and spoil easements. Leeville to Grand Isle: State of Louisiana, Department of Public Works, proposes to construct that portion of work at junction of project and Bayou Lafourche. Due to multiplicity and other complications of ownership, there will be no conveyance of easements to the United States in this section; however, the local cooperating bodies will be requested to obtain and convey to the United States easements over all other lands involved in this reach. Auxiliary channel. Local interests have not as yet obtained perpetual channel and spoil easements for the project nor arranged for removal or relocation of improvements situated thereon. They have, however, furnished a resolution wherein it is stated that interfering pipelines will be relocated prior to our contractor reaching the pipeline sites. Terminal facilities. There are numerous private warehouses, wharves, and stiff-leg derricks for handling cane along bayou. At Lockport, Barker Barge Line has 382 NEW ORLEANS, LA., DISTRICT a barge wharf with covered shed, and Southern Pacific Railroad maintains a large wharf with covered shed. At Golden Meadow each of the seafood canneries has docking facilities suitable for its needs. Four oil companies have docks at Leeville for transferring production of Leeville oil fields to barges. Facilities considered adequate for existing commerce. Operations and results during fiscal year. New work by hired labor consisted of general engineering and planning. Maintenance by hired labor consisted of condition and operation studies and channel patrol. Condition at end of fiscal year. Construction of existing project was initiated in fiscal year 1939 and is 16 percent complete. Dredging between Larose, La., and Gulf of Mexico was completed in 1939 and that segment between Lockport and Napoleonville, La., is in an inactive status due to lack of right-of-way and spoil area. Jetties at mouth of Belle Pass were completed in 1939, and later damaged by storm action, which required placement of additional stone adjacent to both sides of steel sheet pile jetties in 1940, and repair and extension of jetties in 1941. During fiscal year 1948 stone jetties were repaired and extended inland about 700 feet from shoreline; and steel sheet pile section was strengthened for about 250 feet gulfward of stone jetties, by placement of stone on both gulf and bayou sides. On May 31, 1949, an automatic tide gage for recording hurricane and storm tides was installed. Modification of July 14, 1960, was initiated in February 1963 and is 12 percent complete, with 12- by 125-foot channel completed in September 1963 from Leeville to 12-foot contour in Gulf of Mexico, the 9- by 100-foot channel completed in August 1966 from Golden Meadow to Leeville, and the 9- by 100-foot channel from Golden Meadow to Leeville completed in August 1966. Controlling depths, mean low gulf: (October 1969), bar and entrance channel, 14 feet; to mile 13.4 (Leeville bridge), 10 feet; to mile 21.9 (Golden Meadow), 8 feet; to mile 39.1 (Larose bridge), 8 feet; (April 1969) to mile 58.2 (Raceland bridge), 5 feet; to mile 73.4 (Thibodaux bridge), 6 feet. Total cost of existing project to June 30, 1970, was $1,926,205, of which $1,169,229 was for new work and $756,976 for maintenance. In addition, $75,563 was expended for rehabilitation (Code 820). The Greater Lafourche Port Commission requested, and was granted a permit to dredge a new channel 20 by 300 feet wide west of the existing channel from mile 0.76 in Bayou Lafourche to the 20-foot depth in the gulf, and to close the existing jettied channel after completion of the new channel. This work was completed in March 1968 and the Port Commission must maintain the channel at no less than 12 by 125 feet. 6. BAYOUS LA LOUTRE, ST. MALO, AND YSCLOSKEY, LA. Location. From their common head at the small settlement of Yscloskey, Bayou La Loutre flows southeasterly 29.4 miles to Eloi Bay, and Bayou Yscloskey northeasterly 2.2 miles to Lake Borgne. Bayou St. Malo leaves Bayou La Loutre at mile 19.4 flowing northwesterly 6.5 miles to Lake Borgne.

Length of improvements, 30 miles. Normal range of tide, 1 foot; hurricane, 6 feet. Cost of constructing project was $96,916. Local cooperation. Fully complied with. Operations and results during fiscal year. Hired labor conducted condition surveys and investigations. Plans and specifications for maintenance dredging of bar channels have been prepared but work could not be advertised because of problems relating to spoil-disposal areas and oyster leases. Condition at end of fiscal year. Construction of project was initiated in fiscal year 1940 and completed in May 1956. Controlling depths, mean low gulf: Bayou La Loutre (April 1970) bar channel (Lake Eloi), 5 feet; to mile 15 (Bayou St. Malo), 5 feet; to mile 21.7 (Hopedale), 4.5 feet; Bayou St. Malo (January 1970), bar channel, 3 feet; to mile 6.3 (Bayou La Loutre), 3 feet; and Bayou Yscloskey (April 1970), bar channel, 3.5 feet. 7. BAYOU QUEUE DE TORTUE, LA. Location. Bayou Queue de Tortue rises in the western part of Lafayette Parish, La., and flows southwesterly, then westerly between Acadia and Vermilion Parishes, entering the Mermentau River about 5 miles above the head of Lake Arthur. (See U. S. Coast and Geodetic Survey Chart No. 1116 and U. S. Geological Survey quadrangles Lake Arthur and Gueydan.) The stream is 50 to 110 feet wide and about 60 miles long. The section under improvement is 14 miles long, measured through the proposed cutoffs, and extends from the mouth to the Southern Pacific Railroad bridge at Riceville, La. The stream is tidal. The watershed is about 285 square miles. The discharge at low water is about 40 second feet. Existing project. Provides for the removal of obstructions from its mouth to the Southern Pacific Railroad bridge at Riceville, La., and for dredging 10 cutoffs, aggregating 1,765 feet in length, reducing the distance from the mouth of the bayou to the bridge to 383 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 about 14 miles. No channel dimensions were specified. Under ordinary conditions the mean range of tide is about 5 inches at the mouth and nothing at the head, and the extreme range about 10 inches and nothing, respectively. During severe rains there is at times a rise of 6 feet. New work under the project was completed in 1923 at a cost of $33,355. Local cooperation. Fully complied with. Terminal facilities. There are no terminal facilities on the bayou other than a warehouse and a small wharf at mile 6, which is used principally for shipping rice. Landings at the pumping plants are generally made on the banks. The terminals are considered adequate for existing commerce. There are no public wharves open for use of all carriers on equal terms. (For a full description of terminal facilities, see H. Doc. 652, 66th Cong., 2d sess.) Operations and results during fiscal year. Clearing and snagging of the bayou, started by hired labor last fiscal year, was completed August 8, 1969. Both banks of the bayou were cleared from mile 0 to mile 14. Condition at end of fiscal year. Construction was initiated in 1915 and completed March 1923. Controlling depth, mean low gulf: (July 1969) mile 0 to 6.5, 6.5 feet; to mile 13.9, 4 feet. 8. BAYOU SEGNETTE WATERWAY, LA. Location. Bayou Segnette Waterway is a natural water traffic route, located in the lowlands of Jefferson Parish, La., just south of the Mississippi River, opposite New Orleans. The waterway heads at the mouth of an artificial canal known as Company or Westwego Canal, and ends where Bayou Villars is cut by the Intracoastal Waterway. The channel prior to improvement included or traversed in turn, Bayou Segnette, Bayou Bordeaux, Lake Salvador, and Bayou Villars, and is 13.5 miles long. Existing project. The plan of improvement provides for a channel dredged to a depth of 9 feet below mean low Gulf level over a bottom width of 60 feet, commencing at the southern end of Company Canal and following the existing channel of Bayou Segnette (including its cut-offs) southward to approximately mile 6.4; thence southerly via a new landcut lying to the east of Lake Salvador to Bayou Villars. The total length of improvement is 12.2 miles. The channel is to be maintained to a depth of 6 feet until such time as, in the discretion of the Chief of Engineers, maintenance to a greater depth not to exceed 9 feet is economically advisable. The estimate of cost (revised in 1957) is $374,000. Local cooperation. Local interests are required to: furnish without cost to the United States all lands, easements, rights-of-way and suitable spoil-disposal areas necessary for the new work and for subsequent maintenance when and as required; accomplish and maintain without cost to the United States all necessary alterations in pipelines, and drainage and other facilities; hold and save the United States free from damages due to construction and maintenance of the improvements; maintain Company Canal free from vegetative growth obstructive to navigation and provide and maintain therein a minimum depth of 7 feet or a depth equivalent to that maintained in the Federal channel, whichever is the lesser, for a width of at least 30 feet, with transit at published rates open to all on equal terms; provide and maintain a public wharf, not less than 20 feet wide and 200 feet long near the head of Bayou Segnette, accessible by highway and open to all on equal terms; and cooperate with the Corps of Engineers in preventing the release of water hyacinths and other growths obstructive to navigation from local drainage ditches into the proposed improvement. Assurances of local cooperation accepted on August 20, 1956. Local interests have not conveyed acceptable easements to the United States. In July 1966, the Chief of Engineers advised the District Engineer that he is not authorized to contract for any future construction in the project unless prior thereto acceptable land interests are obtained and made available to the United States. Terminal facilities. None. Operations and results during fiscal year. Maintenance by hired labor consisted of surveys and planning for dredging to restore project channel. Condition at end of fiscal year. Construction was initiated January 10, 1957, and is 64 percent complete. Work remaining to complete the project consists of deepening the channel to 9 feet when economically justified. Controlling depths, mean low gulf, were: (Oct. 1969), GIWW to mile 12.2, 5 feet. 9. BAYOU TECHE AND VERMILION RIVER, LA. Location. Bayou Teche has its source in Bayou Courtableau, in St. Landry Parish, and flows southeasterly 125 miles to its confluence with lower Atchafalaya River, about 10.5 miles above Morgan City, La. Vermilion River, also called Bayou Vermilion, is formed by junction of Bayous Fusilier and Bourbeau, west of Arnaudville, La., and flows southwesterly 72 miles to western end of Vermilion Bay. Bayou Teche is connected with Vermilion River by Bayou Fusilier at Arnaudville; and by Ruth Canal, an artificial, privately owned, nonnavigable waterway, constructed for diversion of water from Bayou Teche to Vermilion River for rice irrigation. (Coast and Geodetic Survey Charts 1116 and 1277; Mississippi River Commission alluvial valley maps; and Geological Survey maps.) Existing project. A navigable channel 51 miles long and 8 by 80 feet from 8-foot depth contour in 384 NEW ORLEANS, LA., DISTRICT Vermilion Bay to Gulf Intracoastal Waterway, thence 9 by 100 feet to head of navigation (mile 52) at Lafayette, La.

S. Highway 90 Bridge (mile 36.2); a 750- by 1,000-foot turning basin at upper end with a 35-foot depth; improvement of river from Lake Charles to Phillips Bluff (52.6 miles) by removing logs, snags, overhanging trees, and by dredging; maintenance of existing 12- by 200-foot channel in old channel of Calcasieu River at Cameron, La., which connects with project at mile 2.25; and reconstruction and extension of existingjetties initially to seaward end of east jetty, and further extension to 15-foot depth contour if found advisable to reduce maintenance dredging costs. Improvement is 113.6 miles long. Normal range of tide is 10 inches at mouth, diminishing to zero at Phillips Bluff, extreme range is 14 inches and zero, respectively. Cost of existing project, completed in 1968, except for extension of jetties, if necessary, to 15-foot-depth contour, was $27,311,396. Estimated cost of this extension (July 1967) is $10,300,000. Estimated non- Federal cost of the existing project is $3,240,000. In addition, Coast Guard is to provide navigation aids at an estimated cost of $427,000. Local cooperation. Local interests furnished all rightsof- way and spoil disposal areas for completed features. For construction and future maintenance of modification authorized by 1960 River and Harbor Act, local interests must furnish lands, rights-of-ways, and spoil-disposal areas; alter pipelines, cables, wharves, oil wells, and any other facilities and hold the United States free from damages. Assurances were accepted and right-of-entry furnished for the modification. The local agency is presently effecting transfer to the United States the few remaining tracts with acceptable title evidence. Terminal facilities. Facilities at Port of Lake Charles are owned by Lake Charles Harbor and Terminal District and operated by a board of commissioners. In addition to municipally owned terminals, there are several privately owned and operated wharf structures on existing ship channel. (For further details, see Port Series No. 19, vol. 1, "Port St. Joe, Fla., Pensacola, Fla., Baton Rouge, La., Panama City, Fla., Pascagoula, Miss., Lake Charles, La., Gulfport, Miss." revised 1957, and Folio of Navigation Maps Intracoastal Waterway, New Orleans to Port Arthur, 1962, 10th edition, published by Mississippi River Commission.) Operations and results during fiscalyear. Maintenance by hired labor consisted of condition and operation studies, operation and maintenance of the salt-water barrier, and maintenance dredging by the dredge Langfitt. The dredge Langfitt removed 7,982,000 cubic yards of shoal between miles 0 and minus 10 in restoring channel during the period November 6 to 27, 1969, and February 5 to April 8, 1970. Maintenance by contract consisted of restoring the channel from miles 15.5 to 29.7. Preliminary work was started in the previous fiscal year and completed April 20, 1970, with the contract dredges Galveston, Louisiana, and Buster Bean removing 10,906,958 cubic yards this fiscal year. Restoration of the 12- by 200-foot channel to Cameron was initiated in the previous fiscal year by the contract dredge Galveston and completed July 6, 1969, with the removal of 49,320 cubic yards this fiscal year. Condition at end of fiscal year. Construction under the existing project was initiated in fiscal year 1939 and completed October 1968, except extension of the jetties to 15-foot depth contour, if necessary. See table ll-d at end of chapter for work accomplished under each modification. 386 NEW ORLEANS, LA., DISTRICT A turning basin or ship anchorage for vessels using waterway was constructed from April to June 1952, between St. Johns Island and vicinity of Cameron, La., about 1.1 miles. Calcasieu Pass jetties, initiated under previous project and completed in May 1942, extended to 10-foot depth contour. East jetty, about 8,620 feet long, was built to about 6 feet above mean low gulf, and extends seaward from existing gulf shoreline for 6,820 feet. West jetty, 8,050 feet long, was built to about 4 feet above mean low gulf and extends seaward from existing gulf shoreline for 6,795 feet. Controlling depths, mean low gulf: (Feb. 1970) bar and jetty channel, 40 feet; to Lake Charles, 38 feet; to mile 38.7 (salt-water barrier), 14 feet; to mile 60, 9 feet; to mile 85.9, 0 feet; (Aug. 1969) to Cameron, 13 feet. Subsequent to these surveys, the project channel was restored as above indicated. Total cost of existing project to June 30, 1970, was $40,399,524, of which $27,311,396 was for new work and $13,088,128 for maintenance. In addition, $107,837 was expended for minor rehabilitation (Code 820). 12. CALCASIEU RIVER SALT-WATER BARRIER, LA. Location. Just upstream of Lake Charles, La. Existing project. Provides for salt-water barrier structure with five tainter gates in a new bypass channel; a parallel channel with a navigation gate (sector type); a closure dam in existing channel of Calcasieu River; and revetment along a section of river bank upstream from diversion channel to prevent a natural cutoff. Local cooperation. Fully complied with. Operations and results during fiscal year. Hired labor forces partially completed preparation of operations and maintenance manual for the project. Operation and maintenance of the structures and channels was accomplished under the allotment for Calcasieu River and Pass, La. Condition at end offiscalyear. Construction was initiated April 26, 1965, and completed March 27, 1968, except bank stabilization which may be required at a later date. 13. FRESHWATER BAYOU, LA. Location. In Vermilion Parish, La., between Atchafalaya and Calcasieu Rivers, from Gulf Intracoastal Waterway, mile 161.2 west of Harvey lock, to 12-foot contour in Gulf of Mexico near Freshwater Bayou. Waterway is routed 22.6 miles along Schooner Bayou Cutoff, Schooner Bayou, Six Mile Canal, Belle Isle Canal, and Freshwater Bayou. Existing project. Provides for dredging a new 12- by 125-foot channel from Gulf Intracoastal Waterway, mile 161.2 west of Harvey lock, to 12-foot contour in Gulf of Mexico near Freshwater Bayou, construction of an 84- by 600-foot lock with a depth of 16 feet over sill near Gulf of Mexico; and construction of jetties from shoreline to 6-foot depth contour in Gulf of Mexico, if maintenance dredging of channel without jetties proves to be more expensive than construction and maintenance of jetties. Until such determination has been made, offshore channel should be dredged and maintained to provide a 12- by 250-foot channel. In event jetties are provided, offshore section should then be maintained to 12- by 125-foot project in jettied reach, and 250 feet beyond. Cost of existing project, completed in 1968, except for construction of jetties at a later date, if necessary, was $7,116,224 Federal and a $16,060 cash contribution. Estimated cost of construction of jetties (July 1967) is $2,248,000. Estimated non-Federal cost for the existing project is $206,000. In addition, Coast Guard is to provide navigational aids at an estimated cost of $23,000. Local cooperation. Fully complied with. Terminal facilities. Extensive public and private terminal and transfer facilities do not exist in area, and none would be required for improved channel. Private terminals exist at site of oil and gas operations in area and sufficient private and public wharf facilities are along Gulf Intracoastal Waterway and its connecting waterways. Sites are available along proposed improvement for construction of any additional private and public terminals that might be required for utilization of channel. Operations and results during fiscal year. Maintenance by hired labor consisted of operation and ordinary repairs o lock, condition and operation studies, and preparation of plans and specifications for maintenance dredging of channel. Condition at end of fiscal year. Construction was initiated April 1963 and completed August 1968, except for construction of jetties at a later date, if required to reduce the cost of maintenance dredging. 14. GULF INTRACOASTAL WATERWAY BETWEEN APALACHEE BAY, FLA., AND MEXICAN BORDER (NEW ORLEANS DIST.) Location. Section of Gulf Intracoastal Waterway within New Orleans District extends from Lake Borgne Light 29 near mouth of Rigolets, to Sabine River, La., and Tex. Section from Lake Borgne Light 29 to Mississippi River follows Rigolets and Lake Pontchartrain to lake end of State-owned Inner Harbor navigation canal, thence via this canal to Mississippi River, a distance of 40.5 miles. Public Law 675, 77th Congress, modified project to provide for a landcut through marsh from Rigolets to a point on Inner Harbor navigation canal about 2.25 miles from Mississippi River, eliminating passage through Lake Pontchartrain and five drawbridges, a distance of 30.8 miles to Mississippi River by this route. From Inner Harbor navigation canal to entrance to Harvey lock, route follows Mississippi River for 5.5 miles. Section 387 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 from Mississippi River to Atchafalaya River, La., leaves Mississippi River through Harvey lock about 3.3 miles above Canal Street and follows Harvey Canal No. 1 and Bayou Barataria to Bayou Villars, a landcut south of Lake Salvador to Harvey Canal No. 2, Harvey Canal No. 2 to Larose, La., and a landcut to Houma, La., thence over a landcut south of Bayou Black and Bayou Cocodrie, thence through Bayou Cocodrie and a landcut to Bayou Black; thence through Bayou Black, Bayou Chene, and Bayou Boeuf to Atchafalaya River, about 0.5 mile south of Morgan City, La., a total of 95.5 miles. Alternative connection with Mississippi River in vicinity of Algiers, La., about 10.3 miles below Harvey lock, consisting of a lock and landcut about 9 miles long intersecting Intracoastal Waterway at about mile 6, is complete. An alternative route from Mississippi River follows Bayou Plaquemine passing Indian Village, La., and continuing on through lower Grand River to and through a lock at Bayou Sorrel in East Atchafalaya basin protection levee, thence through levee borrow pit to Berwick Bay; and thence through Berwick Bay to Morgan City, La., a total of 56 miles. This alternative route was enlarged from vicinity of Morgan City to Indian Village, La., and extended from Indian Village, La., through Bayou Grosse Tete and a new landcut to and through a new terminal lock and entrance channel to Mississippi River in vicinity of Port Allen, La., a total of 65 miles. Section from Atchafalaya River to Vermilion River, La., begins at western end of Mississippi-Atchafalaya section and follows Atchafalaya River about 2.5 miles, portions of Little Wax Bayou, Possum Bayou, cutoffs, a landcut passing through North Bend Plantation to Bayou Bartholomew, Bayou Bartholomew to Little Bay, a landcut skirting north edge of Cote Blanche Island and west edge of Weeks Island to Vermilion River, about 24 miles below Abbeville, La., a total of about 63.6 miles. Franklin Canal, St. Mary Parish, La., extends southwesterly from Franklin, La., on Bayou Teche, for 5.5 miles to Bayou Portage, a section of "The Inland Waterway from Franklin to the Mermentau River, La.," and through bayou for 0.75 mile to Gulf Intracoastal Waterway, 121 miles west of Harvey lock. Section from Vermilion River to Mermentau River, La., begins at western end of Atchafalaya-Vermilion section and follows Vermilion River 1.3 miles, a part of Schooner Bayou cutoff canal, and a landcut running generally northwesterly to Mermentau River at a point about 0.5 mile above its entrance into Grand Lake and about 16 miles below town of Lake Arthur, La., a total of about 42.7 miles. Vermilion lock was constructed about 1.75 miles west of Vermilion River to prevent ingress of salt water from Vermilion Bay. Section from Mermentau River to Calcasieu River, La., begins at western end of Vermilion-Mermentau section and follows Mermentau River upstream for about 1.5 miles, a landcut running west-southwesterly to Lake Misere, passing north of lake and Bayou Misere, westerly to Sweet Lake, south and west of Sweet Lake, northwesterly to Bayou Tete Bois, through Bayou Tete Bois, Black Bayou, and cutoffs to a point on Calcasieu River about 16.6 miles below city of Lake Charles, La., a total of about 37.1 miles. Calcasieu lock was constructed near intersection of Calcasieu River and Intracoastal Waterway, mile 238 west of Harvey lock, Calcasieu Parish, about 16.6 miles below Lake Charles, La. Section from Calcasieu River to Sabine River, La. and Tex., begins at western end of Mermentau- Calcasieu section, and follows Calcasieu River upstream about 1.6 miles, a landcut running southwesterly 2.8 miles, thence west 22 miles to Sabine River at a point about 3 miles below Orange, Tex., a total of about 27.1 miles. (See Coast and Geodetic Survey Charts 878-884, inclusive; Mississippi River Commission alluvial valley map and Rigolets, Chef Menteur, St. Bernard, New Orleans, Barataria, Baton Rouge, Grosse Tete, Chicot Lake, Foster, Napoleonville, Morgan City, Belle Isle, Bayou Sale, Jeanerette, and Derouen quadrangles; Geological Survey maps, Cutoff, Houma, Gibson, Abbeville, Forked Island, Grand Lake East, Grand Lake West, Lake Charles, Sulphur, and Orange quadrangles; and folio of navigation maps of Intracoastal Waterway, gulf section, Port Arthur, Tex., to New Orleans, La.) Previous projects. For details see page 544 of 1963 Annual Report. Existing project. Provides for a waterway 384.1 miles long within the district, 16 feet deep and 150 feet wide, from Mississippi River to Atchafalaya River, except in vicinity of Houma, mile 50.5 to 63.5, which is to be maintained at 12 by 125 feet; a channel 16 by 150 feet through bypass route around Houma, La., mile 50.5 to 63.5, and through alternative connection in Mississippi River below Algiers, La., about 9 miles long, a channel 16 by 200 feet from Atchafalaya River to Sabine River; a channel 12 by 150 feet in section between Lake Borgne Light No. 29 and New Orleans (via landcut through marsh and Inner Harbor navigation canal), 33.1 miles long; an alternative route 9 feet deep by 100 feet wide between Lake Borgne Light No. 29 and New Orleans (via Rigolets, Lake Pontchartrain, and Inner Harbor navigation canal), 40.5 miles long; a channel 12 feet deep and 125 feet wide for Plaquemine-Morgan City alternative route from Mississippi-Atchafalaya section of waterway, in vicinity of Morgan City, through Lower Atchafalaya River (Berwick Bay) and borrow pit of East Atchafalaya protection levee to and through Bayou Sorrel lock which was constructed under existing project "Flood control, Mississippi River and tributaries," thence through Lower Grand River to Indian Village, and thence by way of Bayou Grosse Tete and a new landcut to and through a new terminal lock and entrance channel to Mississippi River in vicinity of Port Allen, La., opposite lower limit of Port Baton Rouge; a channel 9 feet deep and 100 feet wide from Indian Village on Plaquemine-Morgan City alternative route through Bayou Plaquemine and Plaquemine lock to Mississippi River at Plaquernine, 388 NEW ORLEANS, LA., DISTRICT La., improvement of Franklin Canal as a connecting channel from Gulf Intracoastal Waterway (mile 121) to Franklin, La., to afford a channel 8 feet deep and generally 60 feet wide with a width of 100 feet in its upper 300 feet; and a salt-water guard lock (Calcasieu lock) in waterway at mile 238 west of Harvey lock. Project also provides for: widening at bends; passing places; mooring basins; locks or guard locks; such railroad bridges over artificial cuts as are necessary; purchase of pipeline dredge; construction and operation of new drainage canals and pumping facilities to restore parish drainage systems where intercepted; construction of movable bridges at Missouri Pacific Railroad and State Highways 31 and 996 (in lieu of State Highway Bridge 31, a tunnel was constructed, and additional cost over estimated cost of bridge was borne by local interests); fixed-trestle bridges for crossing proposed landside drainage canals; lift bridges at Louisiana Highway 168, Port Allen, La., at Texas & Pacific Railway, Port Allen, La., and at Texas & Pacific Railway, Morley, La.; and for annual payments to Board of Commissioners of Port of New Orleans for use of a portion of Inner Harbor navigation canal. Length of waterway within district is 384.1 miles via northerly or Port Allen route, and 229.4 miles via southerly or Harvey Canal route. Normal range of tide, 10 inches; extreme range, 14 inches. A severe storm may cause a high tide of from 6 to 9 feet. Estimated cost for new work, exclusive of amounts expended on previous projects, is $98,193,827 Federal and $15,242,000 non-Federal, divided as follows: Algiers lock and canal, completed June 1961, $15,895,924 Federal, and $2,185,000 non-Federal; Plaquemine-Morgan City route, completed October 1963, $26,869,372 Federal, and $2,250,000 non-Federal; and remainder of waterway (July .1970), $55,428,531 Federal and $10,807,000 non-Federal, including $32,600,000 Federal and $10,800,000 non- Federal for modification of October 1962, and $7,360,000 Federal and $7,000 non-Federal for replacement of Vermilion Lock. In addition, the Coast Guard is to provide navigation aids at an estimated cost of $66,000. Construction of bulkheads and jetties at Lake Borgne and Chef Menteur, La., is considered inactive and excluded from foregoing cost estimate. Estimated cost (1956) of this item is $440,000. Construction of a double-leaf bascule, four-lane highway bridge provided for under this project has become unnecessary because portion of project over which bridge was to be constructed was incorporated in project "Mississippi River-Gulf Outlet" which provides for a larger bridge. Bayou Sorrel and Bayou Boeuf locks were constructed and are being maintained and operated with flood control, Mississippi River and tributaries, funds. Therefore, construction, maintenance, and operation costs are not included in approved estimates referred to before. (See table ll-E at end of chapter for locks on Gulf Intracoastal Waterway in New Orleans District.) Local cooperation. Algiers lock and canal: All assurances required for construction were furnished. Local agency has failed to convey all fee and easement tracts with acceptable title evidence to the United States. However, authority has been received to accept the interests conveyed as best available from local agency with the understanding that the United States rely upon assurances of local cooperation should any claims against the United States occur as a result of failure of local agency to complete transfer of title. Plaquemine- Morgan City alternative route: All assurances required for construction were furnished. Title by United States has been acquired to all but 35 tracts, for which local agency failed to comply fully with curative requirements in title certificate. Authority was given to accept the tracts conveyed as best available from local interests and to rely upon assurances of local cooperation furnished by local agency should any claims against the United States occur as a result of failure of local agency to complete transfer of title. Modification authorized by River and Harbor Act of 1962: Local interests must furnish lands, rights-of-way, and spoil-disposal areas for enlargement and future maintenance of project, make alterations to utilities; construct, maintain, and operate all bridges desired in connection with bypass channel around Houma, La.; and hold the United States free from damages. Assurances were requested in April 1963; however, none of 11 local agencies involved has furnished assurances requested. Main objection to participation is requirement that local interests be responsible for alteration of utilities. Assurances of local cooperation for the replacement of the existing Vermilion lock were requested of the Vermilion Parish Police Jury on September 10, 1968. The Police Jury, by letter dated April 9, 1969, has indicated its willingness and capability of providing the requirements of local cooperation for the project, when funds are available. Terminal facilities. Large terminal and transfer facilities, suitable for receiving and shipping commodities by barge, are available at principal cities in Louisiana; namely, New Orleans, Baton Rouge, Harvey, Morgan City, and Lake Charles. Facilities at New Orleans are on Inner Harbor navigation canal. Canal and facilities were leased from Board of Commissioners, Port of New Orleans, April 1, 1944, and are now operated by the United States, toll free, 24 hours per day. At Morgan City, on Atchafalaya River, there are two large and three small wharves open to all without charge. Otherwise facilities are confined to privately owned piers, wharves, or oil docks. Facilities considered adequate for existing commerce. Operations and results during fiscal year. New work by hired labor: Surveys, borings, and entrance alinement have been complete for the replacement of Vermilion lock. The general design memorandum is about 50 percent complete. Maintenance by hired labor: Real 389 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 estate activities, condition and operation studies, noncooperative stream gaging, investigation and surveys, condition surveys, and channel patrol continued. Locks, bridges, and waterways were operated and maintained. Fender systems were repaired at Calcasieu, Harvey, Port Allen, and Vermilion locks. The bulkhead at the Conely property in vicinity of Houma, La., was repaired between April 7 and 10, 1970. Installation of fire protection system at Port Allen lock was started September 23, 1969, and completed March 26,1970. Placement of riprap for bank protection at Algiers and Harvey locks, initiated June 10, 1969, was completed August 12, 1969. Maintenance by contract: St. Claude and Florida Avenue bridges were repaired during the periods November 10 to 24, 1969, and February 2 to 20, 1970, respectively. Dredging included restoring 7.9 miles of the main stem channel intermittently from mile 20.1 to mile 193.7 west of Harvey during the period December 5, 1969, to April 7, 1970, by the dredges Tchefuncta and Paul F. Jahncke. Shoal was removed from the forebays at Inner Harbor navigation canal, Harvey, Port Allen and Algiers locks. The dredge Arkansas removed 79,325 cubic yards between August 30 and 31, from Inner Harbor lock forebay, 24,550 cubic yards between August 6 and 8 from Harvey lock forebay, and 80,000 cubic yards between June 28 and 30 from Port Allen lock forebay. The dredge Vicksburg removed 65,725 cubic yards from Algiers lock forebay during the period August 7 to 12, 1969. Dredging below Bayou Sorrel lock consisted of removing 64,911 cubic yards by the dredge Holland during the period August 9 to 15, 1969. Condition at end offiscalyear. Construction was initiated July 1929 and project as modified is 59 percent complete. For information on completion of segments of waterway, see 1965 Annual Report, pages 523 and 524. Work remaining to complete the project consists of enlarging waterway as provided by 1962 River and Harbor Act, and replacement of Vermilion lock. Construction of bulkheads at Lake Borgne and Chef Menteur are inactive features as this work has not been necessary. Controlling depths, mean low gulf: (Jan. 1970) New Orleans to Lake Borgne, 12 feet; (Jan. 1970) Mississippi River to Sabine River, 12 feet; Algiers alternative route, 12 feet; (Oct. 1970) Morgan City- Port Allen alternative route, 12 feet. Subsequent to March 1967 survey, project channel was restored as above indicated. Total cost of existing project to June 30, 1970, was $110,858,841 of whibh $58,306,088 was for new work, $24,979,153 for maintenance, and $27,573,600 for operation and care of locks and bridges. In addition, $340,159 for new work and $7,005 for maintenance was expended from contributed funds. 15. HOUMA NAVIGATION CANAL, LOUISIANA Location. Extends from Gulf Intracoastal Waterway at mile 59.5 west of Harvey lock southerly anout 16 miles, thence southeasterly 10.5 miles to Terrebonne Bay, and 9.5 miles across bay to deep water in Cat Island Pass. At mile 11.3 above Cat Island Pass, Houma navigation canal crosses Bayou Petit Caillou and 20 miles above Cat Island Pass it crosses Bayou Grand Caillou. No other major waterways are crossed by Houma navigation canal. (See Army Engineer and Geological Survey quadrangle maps; Coast and Geodetic Survey Charts 1050, 1116, and 1116A; and Coast and Geodetic Charts 1274 and 1275, and sheet 7 of "Navigation Maps of Intracoastal Waterway, Gulf Section, New Orleans, La., to Port Arthur, Texas," published by Mississippi River Commission.) Existing project. Provides that United States assume maintenance and operation of Houma navigation canal, constructed by Parish of Terrebonne, to dimensions of 15 by 150 feet. Normal range of tide is 10 inches at mouth and 4 inches at Houma; extreme range, 14 inches at mouth and 6 inches at Houma; wind and tide, 1 to 3 feet at mouth; flood, 3 to 4 feet in upper section. Local cooperation. Local interests must furnish lands and rights-of-way for maintenance of canal and for establishment and maintenance of aids to navigation; furnish suitable spoil-disposal areas; provide alterations to facilities; hold the United States free from damages; and maintain and operate all bridges under construction or to be constructed across the canal. Local interests (under Chief of Engineers' interpretation of H. Doc. 583, 87th Cong., 2d sess.) will not be required to convey title of canal to United States. Assurances were furnished and accepted April 12, 1963. Local cooperating body has furnished temporary spoil areas as required for maintenance dredging of canal. * Operations and results during fiscal year. Hired labor forces continued routine surveys and condition studies and prepared plans and specifications for maintenance dredging land cut channel from GIWW to Cat Island Pass, not continuous. Maintenance by hired labor consisted of restoring approximately 1.04 miles of channel at Cat Island Pass, mile -2.65 to -3.69, by the U. S. dredge Schweizer during the period January 6 to February 3, 1970. Condition at end of fiscal year. Maintenance by the United States commenced in November 1964. Controlling depths, mean low gulf: (Feb. 1970) Gulf Intracoastal Waterway to Light 38 (Terrebonne Bay), 13 feet; to Light 1 and 2 (end of project), 12 feet; Cat Island Pass, 14 feet. 390 NEW ORLEANS, LA., DISTRICT 16. MERMENTAU RIVER, BAYOU NEZPIQUE, AND BAYOU DES CANNES, LA. Location. Mermentau River is formed by junction of Bayous des Cannes and Nezpique, 2.25 miles above Mermentau, La., flows southwesterly, and empties into the Gulf of Mexico. Bayou Nezpique rises in Evangeline Parish, flows southerly and empties into Mermentau River. Bayou des Cannes rises in Evangeline Parish, flows south-southwesterly and empties into Mermentau River. (See Coast and Geodetic Survey Charts 1116 and 1278, and Geological Survey maps, Evangeline, Hathaway, Mermentau, Jennings, Lake Arthur, Gueydan, Thornwell, Latania Lake, Catfish Lake, Grand Cheniere, and Bayou Labauve quadrangles.) Previous project. For details see page 637, 1961 Annual Report. Existing project. Provides a 12- by 125-foot channel in Mermentau River from Gulf Intracoastal Waterway to Lake Arthur; a 12- by 200-foot channel through Lake Arthur and a 12- by 125-foot channel from upper end of Lake Arthur to junction of the Mermentau River and Bayous Nezpique and des Cannes; replacement of existing Lake Arthur highway bridge over Mermentau River with new bridge constructed to current highway standards and with vertical and horizontal clearances of 50 and 200 feet, respectively; and enlargement and realinement of Bayous Nezpique and des Cannes, to provide a 12- by 125-foot waterway from Interstate Highway 10 to the Mermentau River. Mean range of tide on Mermentau River near mouth is 10 inches and near head about 3 inches, extreme ranges being 14 and 5 inches, respectively. Variation of water surface near mouth may be as much as 7 or 8 feet, due to hurricanes on gulf and near head from 8 to 12 feet, due to freshets. Under ordinary conditions, range of tide on Bayous Nezpique and des Cannes is about 3 inches at mouth and nothing at head. Estimated cost for new work (July 1970) is $5,280,000 Federal and $1,400,000 non- Federal, including a cash contribution of $670,000. In addition the Coast Guard is to provide navigation aids at a cost of $51,000. Local cooperation. Local interests shall agree to: provide all lands for construction and maintenance and spoil-retaining works or the costs of such works; hold the United States free from damage due to the project; design and construct a replacement highway bridge at Lake Arthur, La.; bear 17.1 percent of the costs ($670,000 cash contribution), and operate and maintain the bridge; provide and maintain terminal facilities; and accomplish and maintain all modifications to utilities. The improvement of the Mermentau River or of Bayou Nezpique or Bayou des Cannes, may be undertaken independently as the local cooperation therefor is provided, concurrent with, or subsequent to, replacement of the Lake Arthur highway bridge. Assurances have been furnished by the Acadia, Jefferson Davis and Vermilion Parish Police Juries and the Louisiana Department of Highways. The Cameron Parish Police Jury, in its letter of April 18, 1969, reaffirmed its previous position that it did not desire to execute assurances for the project. The State of Louisiana Department of Public Works executed partial assurances on March 26, 1968, covering that portion of the project in Cameron Parish. That part of provision (a) dealing with retaining dikes, bulkheads and embankments was eliminated by the Department. Terminal facilities. Several small, privately owned wharves at Grand Cheniere and a public terminal at town of Lake Arthur. Privately owned terminals for transferring crude oil to barges are: one on Lake Arthur near town of Lake Arthur; one on Mermentau River near town of Mermentau; two on Bayou Nezpique near Jennings; and four on Bayou des Cannes; one near Evangeline, one at Mermentau, and two near Jennings. Facilities are considered adequate for existing commerce. Operations and results during fiscal year. The general design memorandum was completed. Plans and specifications prepared by the Louisiana Department of Highways for the Lake Arthur, La., bridge replacement were reviewed and approved. Condition at end of fiscal year. Construction not initiated. Total cost of existing project to June 30, 1970, was $180,042 for new work. 17. MERMENTAU RIVER, LA. Location. Work covered by this project is 35 to 70 miles southeast of Lake Charles, La., along lower Mermentau River below Grand Lake, mile 25, to Gulf of Mexico; Inland Waterway from Vermilion Bay to White Lake, White Lake to Grand Lake, and from Schooner Bayou to Intracoastal Waterway-gulf section (Schooner Bayou cutoff); North Prong of Schooner Bayou; and waterway from White Lake to Pecan Island, La., and artificial canal, extending from 5-foot depth contour in White Lake, almost due south for about 1.8 miles to Pecan Island. (See Coast and Geodetic Survey Charts 1277 and 1278, and Geological Survey maps.) Existing project. Flood control, navigation, irrigation, and salinity control in coastal marsh of lower Mermentau River Basin and channel enlargement of lower Mermentau River below Grand Lake, mile 25, to a minimum section of 3,000 square feet below mean low gulf level for discharge of floodflows; construction of a sector gated control structure at Catfish Point, mile 24 above mouth of Mermentau River, for discharge of floodflows and control of tidalflows and salt-water intrusion in Mermentau River; channel enlargement and realinement of Inland Waterway from Vermilion Bay to White Lake, 12.04 miles, and from White Lake to Grand Lake, 6.14 miles, to a minimum section of 3,000 square feet below mean low gulf level or interflow 391 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 between lakes and discharge of floodflows; construction of a sector gated control structure in enlarged channel immediately north of abandoned Schooner Bayou lock reservation for discharge of floodflows and control of tidalflows and salt-water intrusion; channel enlargement of North Prong of Schooner Bayou and Schooner Bayou cutoff, 6.69 miles, to 6 by 60 feet, mean low gulf level, for navigation purposes; and maintenance of existing 5- by 40-foot, mean low gulf level, waterway from White Lake to Pecan Island, La., 1.8 miles long, for navigation. In addition, project provides for incorporation of that section of project, "Inland Waterway from Franklin, La., to Mermentau River," west of Vermilion Bay, a waterway that includes Schooner Bayou lock. Project was reclassified as an "Operation and Maintenance, General" project under category, "Navigation (Locks, Dams, Reservoirs, and Canals)" by authority of Chief of Engineers, April 23, 1956. Because of failure of both east and west gates, Schooner Bayou lock was closed by a dike across east approach channel and traffic routed through new control structure. Under ordinary conditions mean range of tide on Mermentau River near mouth is 1.6 feet and near head about 3 inches. Variation of water surface near the mouth may be as much as 7 or 8 feet, due to hurricanes on the gulf, and near head from 8 to 12 feet, due to freshets. Cost of new work, completed in 1956 was $4,631,910. Local cooperation. Fully complied with. Operations and results during fiscal year. Hired labor continued operation and maintenance of Schooner Bayou and Catfish Point Control structures and prepared plans and specifications for maintenance dredging, mile -0.7 to 24.0.

Jetties are composed of a substructure of brush mattresses surmounted by a superstructure of stone and/or concrete blocks and large riprap. Spur dikes are composed of cribwork of round piling filled with willows and stone. Plane of reference is mean low gulf. Variation of water surface is 16 inches at mouths and 10 inches at heads of the passes, due to tides. Extreme range of tides at mouths of passes due to hurricanes is about 10 feet. At New Orleans extreme range of water surface is about 20 feet due to floods. At Baton Rouge Extreme range is about 45 feet due to floods. Estimated cost of existing project (July 1970) is $34,227,000 Federal and $18,000 non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $28,900. Local cooperation. None required, except for modification of project in connection with Mississippi River-Gulf Outlet, which is reported separately. Terminal facilities. Some 100 piers, wharves, or docks serve Port of New Orleans. Most wharves on east or left bank parallel riverbank forming nearly a continuous covered quay about 10 miles long. Public wharves controlled by Board of Commissioners, Port of New Orleans (the Dock Board), cover 62 percent of improved waterfront. These facilities include a shipside grain elevator, general cargo and cotton wharves, fruit landings, bunkering facilities, terminal warehouses, railroad terminals, marine railways, and drydocks and are considered adequate for present commerce. (For further details see Port Series No. 20, "The Port of New Orleans, La." 1958.) A foreign trade zone is located in Port of New Orleans. (City of Baton Rouge has a reinforced concrete dock for deep sea vessels with mechanical-handling facility. Attached to downstream end of wharf is a floating wharf boat 231 by 40.5 feet, of 2,000-ton capacity. Facilities are served by a transfer boat and municipal terminal having a capacity of 40 cars per day. Private terminals for handling oil, grain, bauxite ore, and other products are at points on both sides of river between New Orleans and Baton Rouge. Facilities are considered adequate for existing commerce. (For further details, see "Port Facilities" included in "Flood Control and Navigation Maps of the Mississippi River, Cairo, Ill., to the Gulf of Mexico, Louisiana," published in 1968 by Mississippi River Commission, and Port Series No. 19, Vol. 1, "Port St. Joe, Fla., Pensacola, Fla., Baton Rouge, La., Panama City, Fla., Pascagoula, Miss., Lake Charles, La., Gulfport, Miss.," revised 1957.)

Estimated cost of new work (July 1970) is $1,680,000 Federal and $63,000 non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $9,000. Local cooperation. Local interests must provide without cost to the United States, all lands, easements, and rights-of-way required for construction and subsequent maintenance of the project and for aids to navigation upon the request of the Chief of Engineers, including suitable areas determined by the Chief of Engineers, to be required in the general public interest for initial and subsequent disposal of spoil, and also retaining dikes for disposal of spoil from maintenance dredging, if required; accomplish without cost to the United States such utility or other relocations or alterations as necessary for project purposes; and hold the United States free from damages due to the construction and subsequent maintenance of the project, including any erosion beyond the rights-of-way furnished. Assurances of local cooperation were requested by letter dated January 10, 1969, of the Board of Commissioners of the Port of New Orleans. Such assurances were executed on February 3, 1969, and accepted on behalf of the United States on February 24,1969. Terminal facilities. There are no public wharves located in the area; however, the developer of the area states that the corporation has retained a tract of land at the north end of the Michoud Canal for construction of a public wharf for seagoing and other marine traffic, which would be available to industries without frontage on waterways. Several private facilities are located on the canal and others are anticipated in the future. The Gulf Intracoastal Waterway intersects the Mississippi River-Gulf Outlet approximately 1.5 miles westward from the Michoud Canal. This outlet provides a direct tidewater route for ocean shipping. Operations and results during fiscal year. Hired labor forces are proceeding with the work required for the preparation of the GDM. Surveys have been completed and the remaining design effort is proceeding on schedule. Preparation of the GDM is approximately 20 percent complete. Condition at end of fiscal year. Construction has not commenced. 21. OVERTON-RED RIVER WATERWAY, LA. Location.

Maintenance by contract consisted of dredging at the following locations: Bayou Petit Anse, stations 0 + 00 to 175 + 00, 3.3 miles; approach channel to Avery Canal, stations 0 +00 to 51+00, 1 mile; and Bayou Carlin, stations 83 + 00 to 180+ 00,1.8 miles, and mooring area. A total of 430,381 cubic yards were removed by dredges Conical and Tchefuncta during the period October 20,1969 to April 4,1970. Condition at end offiscalyear. All work under project, as existent at that time, was completed 1939; and work authorized by River and Harbor Act of March 2, 1945, for a 9- by 80-foot channel was completed in 1947, except dredging in vicinity of Texas & New Orleans Railroad bridge and Louisiana State Highway Department bridge crossing Bayou Carlin, which was accomplished during 1949, as was reinforcement of bridge piers under reimbursable agreement, authorized by River and Harbor Act of June 30, 1948. Modification of project authorized by River and Harbor Act of July 14, 1960, was completed March 30, 1962. Jefferson Island Salt Co. has partially complied with furnishing a 9- by 80-foot canal connecting Bayou Carlin with their salt mine, as provided in authorizing document. Chief of Engineers has accepted a 9- by 60- foot channel as partial completion and this 9- by 60- foot channel has been excavated for full length prescribed. Controlling depths, mean low gulf, were: Bayou Petit Anse (Apr 1970) mile 0 (GIWW) to mile 6.1, 6 feet; Bayou Tigre (Aug. 69) mile 0 (Bayou Carlin) to Highway bridge, 4 feet; Bayou Carlin, mile 0 to 7.6, 9 feet. Total cost under existing project to end of fiscal year was $909,442, of which $344,389 was for new work and $565,053 for maintenance. In addition, $47,858 was expended from public works funds for new work. 23. RED RIVER BELOW FULTON, ARK. Location. Red River rises in arid regions of eastern New Mexico, flows generally easterly and southeasterly for 1,300 miles, and enters Atchafalaya and Old Rivers and the Mississippi River at Red River Landing, La., via Old River. (See Geological Survey State maps and Mississippi River Commission alluvial valley quadrangle maps.) 396 NEW ORLEANS, LA., DISTRICT Previous project. For details see page 572, 1957 Annual Report. Existing project. Continuing improvement of Red River from Fulton, Ark., to Atchafalaya River, La., 455.6 miles, by systematic clearing of banks, snagging, dredging shoals, building levees (either alone or in cooperation with riprarian states), closing outlets, revetting caving banks, and preventing injurious cutoffs. Lower end of this project, exclusive of Overton- Red River Waterway, is at Old River, 7.6 miles west of Mississippi River. No proposed channel dimensions are given. Floods ordinarily cause fluctuations of stage between high and low water of from 30 to 45 feet; unusual floods occasionally increase this range about 10 feet. Local cooperation. None required. Terminal facilities. None. Operations and results during fiscal year. Hired labor forces conducted stream gaging and reconnaissance surveys. Condition at end of fiscal year. Maintenance in recent years provides for navigation to Shreveport, La., at medium and high stages. From January to July, prevailing stage is 6 feet and over, and controlling depths are about 4 feet to Fulton, 5 feet to Shreveport, and 6 feet to Alexandria. During remainder of year stages near zero may be expected, with controlling depths less than 1 foot from Fulton to Shreveport, 1 to 2 feet from Shreveport to Alexandria, and 4 feet from Alexandria to mouth of Black River. Controlling depths, mean low water: (Apr.1970) mouth of Black River (mile 33.8) to mile 30, 38 feet; to mile 25, 35 feet; to mile 10, 36 feet; to mile 6 (Barbre Landing), 51 feet. Total cost of existing project to June 30, 1970, was $2,428,765, of which $409,928 was for new work and $2,018,837 for maintenance. 24. REMOVING WATER-HYACINTH (LOUISIANA) Location. Lakes and streams tributary to the gulf coast. Existing project. Removal of plants from navigable waters of Florida, Alabama, Mississippi, Louisiana, and Texas, so far as they are or may become an obstruction to navigation, by any mechanical, chemical, or other means whatsoever; for construction and operation of boats equipped with suitable machinery for such removal; and construction and operation of booms to prevent plants drifting from one stream to another. Local cooperation. None required. Operations and results during fiscalyear. Maximum use of funds available was made by using chemical methods of destruction with mechanical equipment held in reserve for use only when hyacinth jams necessitate it. Work was accomplished in main waterways and their principal tributaries over which a major portion of 451-584 0-72-26 navigation moves. Preventive maintenance work was carried out in secondary streams and feeder areas whenever possible. Feeder areas previously freed of hyacinth and placed on patrol maintenance basis have become infected with alligatorweed which has not proved to be as susceptible to approved chemical methods as water-hyacinth. A total of 8,233 acres of vegetation was treated by chemicals in Bayou Black, Lake Cataouatche and feeder streams, Lake des Allemands area, Lake Dauterive area, Bayou Penchant- Bayou Copasaw area, Gulf Intracoastal Waterway, streams of Maurepas-Pontchartrain Basin, Plaquemine Waterway, Caddo Lake, Bayou Lacassine, and Bayou Teche. There was no necessity for mechanical destruction methods. Operations were conducted in main navigable streams on a recurring basis. These results cannot be considered permanent until vegetation in secondary streams and feeder areas has been destroyed. Condition at end of fiscal year. From 1900 to 1902 a boat with suitable machinery for destroying hyacinth by crushing was operated. From that time until 1937 hyacinths were destroyed through use of a solution of arsenic and caustic soda which was sprayed on vegetation, removal by hand crews, and controlled in their movements by means of booms and barricades. Use of arsenic was discontinued and hand removal supplanted by use of mechanical equipment in conjunction with chemical spray (2,4-dichlorophenoxyacetic acid). Use of booms and barricades has been discontinued. Present methods of control are by means of mechanical rotary saw-type destroyers, and chemical treatment. Excellent results are being obtained on water-hyacinths by these methods. 25. WATERWAY FROM EMPIRE, LA., TO GULF OF MEXICO Location.

Inadequate outlet capacity of Maniece Bayou results in impoundment in swamp for extended periods during rainy season with resulting impairment of drainage on surrounding improved lands and periodic overflow of these lands during moderate storms. Existing project. Diversion of Maniece Bayou through enlarged existing channels and land cuts to enter Red River at mile 362.3, for snagging and clearing existing channel between Red River and mile 0.47, and channel enlargement and realinement between mile 0.47 and 8. This plan was modified to include enlargement and realinement of Maniece and Field Bayous below mile 22.7, including further channel enlargement of Maniece Bayou below mile 8 beyond that already authorized, provides for a low water dam near end of existing left-bank Red River levee, extension of levee by a spoil bank for 3.5 miles to mouth of Maniece Bayou, and construction of an appurtenant interceptor drainage ditch. Cost of new work, completed in 1969, was $970,932 Federal, and $39,293 contributed funds. Local cooperation. Fully complied with. 403 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Operations and results during fiscal year. The remaining cleanup and dressing of spoil under contract for channel enlargement and realinement, mile 7.88 to 22.47 was accomplished and contract was completed August 18, 1969. Condition at end of fiscal year. Construction of the original authorization was accomplished from July 1958 to April 1959, with lower 8 miles of Maniece Bayou cleared, realined, and enlarged. Construction under modification of July 14, 1960, was initiated May 22, 1966, and was completed August 18, 1969. 41. MISSISSIPPI RIVER DELTA AT AND BELOW NEW ORLEANS, LA. (NEW ORLEANS TO VENICE, LA., HURRICANE PROTECTION) Location. Includes land subject to inundation by hurricane tides extending on both banks of Mississippi River from vicinity of city of New Orleans to Gulf of Mexico. Existing project.

Estimated cost of new work (July 1970) is $29,600,000 Federal and $20,300,000 non-Federal, including $16,100,000 cash contributions or equivalent work. Local cooperation. Local interests must furnish lands and rights-of-way for construction and future maintenance; provide alterations to facilities, and maintain and operate project after completion; contribute in cash or equivalent work not less than 30 percent of total project cost; and hold the United States free from damages. Plaquemines Parish furnished assurances for reaches "A", "B", and "C", and they have been accepted. Operations and results during fiscal year. New work by hired labor: Planning and studies for the project continued. Plans and specifications for first lift levee extension, Station 104 + 70 to 340 + 20 (Empire floodgate to Buras), Reach B-1, were completed. Contract was awarded, but work has not yet started. Plans and specifications for second lift levee, Station 0+00 to 98+55, were initiated and are about 40 percent complete. Condition at end offiscal year. Construction was initiated September 1968, and is 6 percent complete, with 1.9 miles of first lift levee embankment completed. Construction of Reach C has been completed by local interests. 42. MORGAN CITY AND VICINITY, LA. (HURRICANE PROTECTION) Location. In south central Louisiana, Morgan City proper and the adjacent areas. It includes the land south of Grand Lake, Six Mile Lake, and Lake Palourde extending from Morgan City westward to Charenton drainage and navigation canal. Lower Atchafalaya River and Wax Lake Outlet, the principal outlets for Atchafalaya Basin Floodway traverse the area. Gulf Intracoastal Waterway crosses the area in an east-west direction. Numerous bayous and artificial canals excavated for drainage purposes or for access to oil developments exist throughout the area. (See Engineer quadrangles Bayou Sale, Jeanerette, Foster, Belle Isle, Point Au Fer, Morgan City, and Lake Decade; and Coast and Geodetic Survey Chart 1116.) Existing project. Morgan City: Construction of about 5.6 miles of new levees along shore of Lake Palourde and west bank of Bayou Ramos and about 0.5 mile of new levee from Southern Pacific railroad embankment near Wyandotte to tie in with Bayou Boeuf lock levee, and construction of three gravity drainage structures. Franklin and vicinity: Enlargement of about 21.6 miles of back levee and construction of about 3.1 miles of new levees to effect a complete closure of area to be protected, construction of one floodgate and five gravity drainage structures, and alteration of existing drainage facilities where necessary. Normal range of tide is 1.6 feet. Storm and hurricane tides have produced elevations up to 10 feet while northerly storms during winter depress the gulf level as much as 3 feet below mean sea level. During low water periods on Atchafalaya River, generally September through November, the effect of tide extends about 35 miles above Morgan City. Estimated cost for new work (July 1970) is $4,960,000 Federal and $2,250,000 non- Federal including $430,000 cash contributions. Local cooperation. Local interests must furnish lands, easements, and rights-of-way for construction and future maintenance, provide relocations and alterations required for project; provide all interior drainage and pumping plants required for reclamation and development of protected areas; maintain and operate all project works after completion, provide assurances that encroachment on existing ponding areas will be prevented unless substitute storage capacity or equivalent pumping capacity is provided promptly, without cost to the United States; contribute in cashject cost, the final determination to be made after construction is complete; and hold the United States free from damages due to construction works. Assurances were furnished by the St. Mary Parish Police Jury and accepted by the United States on July 18, 1968. Operations and results during fiscal year. Hired labor forces and an architect-engineer firm continued studies and investigations in connection with preparation of two general design memorandums, one for the Morgan 404 NEW ORLEANS, LA., DISTRICT City (subareas A & B) unit and one for the Franklin and vicinity unit. These memorandums are 70 percent and 95 percent complete, respectively. Condition at end of fiscal year. Construction has not commenced. 43. RED RIVER BELOW DENISON DAM (NEW ORLEANS DIST.) Location. On Red River and its tributaries below Denison Dam, in Oklahoma, Arkansas, Texas, and Louisiana. (See Geological Survey State maps and folio "Maps of Red River"-1958 edition.) Existing project. Flood Control Act of 1946 approved general plan for flood control on Red River below Denison Dam, Tex. and Okla., which provides for construction of six flood control reservoirs in combination with existing or authorized Federal and non- Federal levee improvements, modified as required, and channel stabilization at locations where levee setbacks are impossible or uneconomical. This act further authorized incorporation of several separate existing projects for flood control along Red River below Denison, above jurisdiction of Mississippi River Commission, into this project. By Public Law 780, 83d Congress, 2d session, as amended by Public Law 218, 84th Congress, 1st session, and Public Law 645, 86th Congress, 1st session plan of improvement was amended to include additional projects as indicated in following lists of reservoirs and local protection works considered in general flood control plan for the Red River below Denison Dam, and existing flood control projects incorporated into project in New Orleans District. (See Table 11-H for new projects and Table 11-I for incorporated projects.) Local cooperation. See individual reports. 44. RED RIVER BELOW DENISON DAM, LEVEES AND BANK STABILIZATION (NEW ORLEANS DIST.) Location. Along both banks of Red River from vicinity of Index, Ark., mile 497, to latitude of Alexandria, La., mile 121 (1938 survey) on north bank, and to latitude of Boyce, La., mile 141, on south bank. Existing project. Provides for modification as required of existing or authorized Federal and non-Federal levee improvements for conveyance of peak flows of design flood with a minimum freeboard of 3 feet, except where a 3-foot superiority for "South Bank Red River Levee" is presently prescribed; and for extension of channel stabilization program envisaged by existing project, "Red River in the Vicinity of Shreveport, La.," by construction of bank protection works at locations where levee setbacks are impossible or uneconomical, and to prevent disruption to transportation facilities when threatened by caving banks, all between Denison Dam and upper limit of Mississippi River backwater, below which is under jurisdiction of Mississippi River Commission. Estimated cost for new work (July 1970) is $25,100,000 Federal and $300,000 non-Federal, including $100,000 contributed funds. Recommended modifications. That the existing project for the Red River below Denison Dam, as it pertains to the Posten Bayou, Arkansas-Louisiana area, be modified to delete the plan of improvement authorized for that area by the Flood Control Act of August 3, 1955, and to provide in lieu thereof for headwater flood protection by construction, in combination with upstream drainage improvements by others, of a major outlet consisting of about 2.5 miles of diversion channel with related control structure and levees, from Posten Bayou to Red River just north of the Arkansas- Louisiana State line. Local cooperation. Local interests must furnish lands, easements, rights-of-way, and spoil disposal areas necessary for construction; hold the United States free from damages; and maintain and operate works after completion. Local interests have been prompt in furnishing levee rights-of-way upon request, except for the following three items of low priority: McKinney Bayou Drainage District, enlargement of approximately 4 miles of intermittently low levee; Garland Levee District, enlargement of approximately 1.3 miles of levee; and Red River Levee District No. 1, enlargement of approximately 4.3 miles of levee. The local agencies are convinced that the flow line lowering produced by complet. d reservoirs has made this work unnecessary. Operations and results during fiscal year. Hired labor forces continued investigations, surveys, preparation of plans and specifications, and real estate activities. Contract work consisted of hydrographic surveys and construction of bank protection works. Construction of board mattress revetment at Cupples Landing, La., R-259.3-R, which started last fiscal year, was completed on September 17, 1969, with 2,500 linear feet of bank protected. This work involved constructing 2,105 squares of lumber mattress and placing 16,232 tons of stone on mattress and upper bank paving. A total of 31,762 tons of stone was placed in construction of a stone dike system of 6 dikes and 200 linear feet of bankhead paving at Williams, La., D- 238.5-R, during the period November 12, 1969, to June 11, 1970. Construction of board mattress at Grand Ecore, R- 185.6-L, started January 6, 1970, and is about 19 percent complete. Work was suspended most of the fiscal year due to high river stages. Condition at end offiscalyear. Construction was initiated in February 1948 and is 55 percent complete, with approximately 149 miles of left bank and 235 miles of right bank levees improved. About 24 miles of banks are protected with stone and pile dikes, standard board, riprap trenchfill revetments, and three cutoffs. 405 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 45.

(See Cincinnati sheet of maps of United States published by Army Map Service, scale 1:500,000.) Previous project. For details see Annual Report for 1896, page 1761. Existing project. Improvement for navigation will provide a channel 9 feet deep and 225 feet wide from mouth to Fayetteville, Ill. Improvement will consist of enlarging present channel where required, making overbank cutoffs to eliminate sharp bends, and construction of a dam at about mile 0.8 with a single lock 84 feet wide and 600 feet long, at an estimated construction cost of $105,560,000 (1970) including a $1,500,000 local contribution. Local cooperation. State of Illinois passed legislation authorizing Illinois Department of Public Works and Buildings to enter into assurances of local cooperation with the United States. These assurances have been furnished and were accepted November 23, 1965. The State is continuing with land acquisition. Operations and results during fiscal year. Construction of the canal, roads, and lock and dam continued. Work was initiated on railroad alterations. Engineering and design continued on remaining construction items. Condition at end of fiscal year. Project is about 22 percent complete. 3. MISSISSIPPI RIVER BETWEEN MISSOURI RIVER AND MINNEAPOLIS, MINN. (ST. LOUIS DIST.) See section of this annual report entitled "Mississippi River between Missouri River and Minneapolis, Minn." 4. MISSISSIPPI RIVER BETWEEN OHIO AND MISSOURI RIVERS Location. Mississippi River rises in Lake Itasca, Minn., and from that lake flows southerly about 2,340 miles and empties into the Gulf of Mexico. Portion included in this report embraces the 195-mile section known as middle Mississippi, between tributary Ohio and Missouri Rivers about 974 to 1,169 miles from the gulf. See folder by Corps of Engineers of Navigation Charts Middle and Upper Mississippi River, Cairo, Ill., to Minneapolis, Minn. Previous projects. For details see page 1879 of Annual Report for 1915, and page 1014 of Annual Report for 1938. Existing project. Provides for obtaining and maintaining a minimum channel depth of not less than 9 feet, a minimum width of not less than 300 feet at low water, with additional widths in bends from mouth of Ohio River (about 974 miles from gulf) to northern boundary of city of St. Louis, mile 191; thence 200 feet wide, with additional width in bends to mouth of Missouri River, mile 195; to be obtained: (1) by regulating works, for closing secondary channels, contracting river by building new banks where river width is excessive and protecting new and old banks from erosion where necessary to secure permanency at an estimated construction cost (1970) of $76,800,000; (2) by dredging to maintain project channels; (3) by construction of works authorized for Chain of Rocks reach in 1945 River and Harbor Act, which approved a comprehensive plan for development of the river at Chain of Rocks to provide for construction of a lateral canal at an estimated construction cost (1970) of $55,200,000 and (4) by construction of a fixed-crest rockfill dam about 900 feet below Chain of Rocks Bridge, authorized by 1958 River and Harbor Act, at cost of $4,353,000, excluding $7,000 costs to Coast Guard for aids to navigation. Estimated cost of new work (1970) is $136,353,000. A small boat harbor opposite Chester, Ill., is inactive and excluded from foregoing cost estimate. Estimated cost (July 1960) of this portion is $166,600 including $55,000 non-Federal contribution, and excluding $1,000 Coast Guard cost. See House Document 669 (76th Cong., 3d sess.) for report of Chief of Engineers dated February 27, 1940, containing a general plan for improvement of Mississippi River between Coon Rapids Dam and mouth of Ohio River for purposes of navigation, power development, flood control, and needs of irrigation. Local cooperation. None required. Terminal facilities. Considered adequate for existing commerce. Operations and results during fiscal year. Regulating Works: Contract work continued on stone dike construction as did engineering and design and supervision and administration. Chain of Rocks: Engineering and design for guidewalls and tie-down of upper sill continued. Dam 27: Project is complete. Maintenance: Work consisted of 19,155 feet of dike repair and 5,550 feet of revetment repair. U. S. plant hired labor performed channel dredging at 20 locations, removing 4,230,400 cubic yards of material from main channel. Channels dredged had a combined length of 13.6 miles, an average width of 290 feet, and an average gain in depth of 5.5 feet. Condition and operation studies, recreation planning, engineering and design, and operation and maintenance of Lock 27 and Dam 27 continued. Condition at end of fiscal year. Construction on existing project began in 1881 and project has been in beneficial use practically from its inception. Work on the project is about 80 percent complete. Work required to complete the project includes construction 448 ST. LOUIS, MO., DISTRICT of 48,095 linear feet of dikes; 35,000 linear feet of revetment; removal of 100,000 cubic yards of rock; removal of 100,000 cubic yards by dredging; upper and lower guidewalls at Lock No. 27; and alterations to sills. Channel as a whole has been greatly improved by the work completed to date. Dredging is required at low stages to remove temporary shoals and maintain required channel depths. Navigation season formerly extended from mid-February to mid-December, the river generally closed by ice remainder of year. However, in recent years increased demands of commerce and use of steel-hull boats have combined to extend navigation season throughout the year except when blocked by heavy ice or gorges. River is generally above 10-foot stage, St. Louis gage, from latter part of February to latter part of August, during which time project channel depths generally prevail without dredging. Mean stage of river, St. Louis gage, was 13.23 feet for fiscal year 1969 and 12.16 feet for fiscal year 1970. A study is underway to determine whether project criteria need to be revised in order to assure a dependable 9-foot project depth. 5. OTHER AUTHORIZED NAVIGATION PROJECTS. See table 14-E at end of text. FLOOD CONTROL 6. EAST ST. LOUIS AND VICINITY, ILL. Location. In St. Clair and Madison Counties, Ill., on the left bank of the Mississippi River between river miles 175 and 195 above the Ohio River. Project includes all bottom lands between bluffs on the east and Mississippi River and Chain of Rocks Canal on the west, and extends from Cahokia diversion channel on the north to Prairie du Pont Creek on the south. (See Corps of Engineers Navigation Charts, Middle and Upper Mississippi River, Cairo, Ill., to Minneapolis, Minn.) Existing project.: The 1936 Flood Control Act authorized raising and enlarging existing levee system by construction or reconstruction of 19.8 miles of levee, including 3.1 miles of floodwall, together with necessary appurtenant works consisting of gravity drainage structures, highway and railroad closure structures, alterations and reconstruction of existing pumping plants, alterations to railroad bridges and approaches at levee crossings, service roads on levee crown, and seepage control measures. Work under this authorization will provide the area protection against a flood of about 200-year frequency. The completed 10 miles of levee along Chain of Rocks Canal and Lock 27 provides flood protection on the landward side integral with and to the same degree as the East St. Louis levee. Estimated cost of work under this authorization is $21,955,000 (1970). The Flood Control Act of 1965 modified existing project to provide for channel improvements, diversion ditches, flood plain detention areas, a reservoir on Little Canteen Creek, and a pumping plant to considerably reduce damages resulting from interior flooding. This act also authorized reconstruction of a channel stabilization dam in Cahokia Creek diversion channel to provide protection to adjacent levees and bridges from scour and eventual loss. Estimated Federal cost of work under this authorization is $11,100,000 (1970). Local cooperation. Fully complied with for work under 1936 authorization. For work authorized by Flood Control Act of 1965, local interests must provide lands, easements, and rights-of-way for construction; hold the United States free from damages due to the construction works; make relocations of and modifications to highway bridges, streets, roads, sewers, and utilities; maintain and operate all the works after completion including removal of silt and debris from impoundment areas and channels in accordance with regulations prescribed by the Secretary of the Army; prevent encroachment on improved channels, ponding areas, and detention areas including the reservoir, and if encroachment occurs or capacities are impaired, provide substitute storage or equivalent pumping capacity promptly without cost to the United States; and at least annually notify interests affected that the project provides only partial protection from the larger floods. East Side Levee and Sanitary District, the potential sponsor, has legal authority to execute assurances for the project, but does not have financial capability at this time. The low water dam has been designated as a separable and usable segment of the project for the purpose of obtaining local assurances. The Wood River Drainage and Levee District and East Side Levee and Sanitary District are able to furnish the requirements of local cooperation (Section 3, Flood Control Act of 1936) for the channel stabilization dam. The State of Illinois is currently studying the feasibility of sponsoring the interior drainage project. Operations and results during fiscal year. Preconstruction planning was continued on project modifications authorized by Flood Control Act of 1965. Condition at end of fiscal year. Project constructed under authority of Flood Control Act of 1936 is essentially complete. Construction has not started on modifications authorized by Flood Control Act of 1965. 7. HARRISONVILLE AND IVY LANDING DRAINAGE AND LEVEE DISTRICT NO. 2, ILL. Location. In Monroe County, Ill., on left bank of the Mississippi River between river miles 141 and 156 above the mouth of Ohio River. (See St. Louis, Mo., map published by Army Map Service, scale 1:250,000.) Previous project. For details, see page 676 of Annual Report for 1957. 449 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Existing project. Project area contains about 27,800 acres protected from floods of the Mississippi River and Fountain Creek by levees. However, when Mississippi River stage exceeds 15 feet on the St. Louis, Mo., gage, substantial damage results from impoundment of precipitation which falls on the area, runoff from adjacent hill land, and Mississippi River seepage. The 1962 Flood Control Act provides for construction of two pumping stations to reduce interior flooding. Estimated cost (1970) is $2,000,000. Local cooperation. Local interests must provide lands, easements, and rights-of-way for construction; hold the United States free from damages; maintain and operate project after completion; prevent encroachment on improved channel and ponding areas and, if ponding areas and capacities are impaired, provide substitute storage capacity or equivalent pumping capacity promptly without cost to the United States. Local interests have indicated their willingness to provide necessary cooperation. Operations and results during fiscal year. Preconstruction planning was continued on project modifications authorized by Flood Control Act of 1962. Condition at end of fiscal year. Project constructed under authority of Flood Control Act of 1936 is complete. General design memorandum is being revised in accordance with recommendations of higher authority. 8. KASKASKIA RIVER, ILL. Location. Rises in Champaign County, Ill., about 5 miles northwest of Urbana, in east-central part of the State. It flows generally southwesterly about 325 miles and empties into the Mississippi River about 8 miles above Chester, Ill., or 118 miles above mouth of Ohio River. (See Nashville and Cincinnati sheets of maps of United States, published by Army Map Service scale 1:500,000. Also Geological Survey quadrangle maps, 1:62,500.) Existing project. Provides for construction of a dam at Carlyle and five levee projects between Carlyle and New Athens authorized by 1936 Flood Control Act, and construction of a dam at Shelbyville, six levee projects along river between Cowden and Vandalia, and a local protection project at New Athens, all authorized by 1958 Flood Control Act. Under the plan, Carlyle Lake and Lake Shelbyville would be operated as a multiplepurpose project for local and Mississippi River flood control, domestic and industrial water supply, releases in the interest of navigation on the Mississippi River, fish and wildlife conservation, and recreation. The 11 levee projects would provide protection to about 54,610 acres of land. In view of inclusion of previously authorized Carlyle Lake and the levees between Carlyle and New Athens in recommended plan, general comprehensive plan for flood control and other purposes in Upper Mississippi River Basin, approved by 1938 Flood Control Act, was modified by deleting Carlyle Lake and levees between Carlyle and New Athens. Flood Control Act of 1965 modified the Flood Control Act of 1958 to: (a) delete requirement that local interests make a cash contribution to the cost of levees between Cowden and Vandalia because of changed land use, and (b) require that local interests make a cash contribution equal to full cost of acquisition of flowage easements in those lands acquired by the United States which, upon completion of the levee in District No. 22, will not be required for construction, operation and maintenance of Carlyle Lake. (See table 14-C.) Operations and results during fiscalyear. Construction and land acquisition continued on Carlyle Lake and Lake Shelbyville and construction was completed on New Athens. Preliminary planning continued on Vandalia District No. 21 and Dively District No. 23. Maintenance: Continued on Carlyle and Shelbyville. Condition at end of fiscal year. See individual reports for Carlyle, Shelbyville, New Athens, Vandalia District No. 21, and Dively District No. 23. Due to lack of local interest and support at this time, levee districts Nos. 3, 4, 8, 10, 13, 22, 27, 28, and 28A are in an inactive category. 8A. CARLYLE LAKE. Location. Dam is on Kaskaskia River at mile 107, about 1 mile upstream from Carlyle, Ill. Reservoir extends north-eastward to river mile 153, through Clinton, Marion, Bond, and Fayette Counties, Ill. (See Cincinnati sheet of maps of United States published by Army Map Service, scale 1:500,000. Also see Geological Survey quadrangle maps, scale 1:62,500.) Existing project. A compacted earthfill dam with a concrete spillway section. Spillway structure consists of an ogee overflow section surmounted by four 38- by 39- foot tainter gates. Dam is 67 feet above streambed and 6,570 feet long. Because of topography near dam, it was necessary to construct two earthfill saddle dams east of Carlyle, in order to contain maximum pool level proposed for reservoir. A loop levee was constructed for protection of Keyesport, Ill. Relocation or alterations were required to Chicago, Burlington & Quincy Railroad, highways, pipelines, oil field facilities, water supply facilities, power and telephone lines, and cemeteries. Maximum reservoir area is 57,500 acres and maximum storage capacity is 983,000 acre-feet; permanent pool area is 26,000 acres. Total project cost (1970) is $42,021,000, of which $8,223,400 is for lands and damages. Local contribution toward cost of project is $3,291,000 for water supply. Local cooperation. In accordance with provisions of authorizing act, cost of storage to be allocated to water supply in Carlyle Lake and annual cost of operation and maintenance of such storage would be reimbursed by the users. State of Illinois executed a contract with the United States providing for payment of 7.85 percent of cost of project and 8.62 percent of actual 450 ST. LOUIS, MO., DISTRICT Federal costs for operation and maintenance. Percentages set forth were determined by separable costremaining benefits methods. Contract was approved by the Secretary of the Army. State of Illinois is currently making payments thereunder. Operations and results during fiscal year. Planning and design and land acquisition are essentially complete. Construction continued on recreation facilities and also is essentially complete. Maintenance: Hired labor forces performed operation and maintenance of Carlyle Lake. Condition at end of fiscal year. Construction was initiated in November 1958. The dam is complete. To date, 36,696 acres of land have been acquired in fee and easements on an additional 25,412 acres. Project is essentially complete. 8B. LAKE SHELBYVILLE Location. Dam is on the Kaskaskia River at mile 221.8, about one-half mile upstream from Shelbyville, Ill. Lake will extend northeastward to approximate river mile 275 through Shelby, Moultrie, and Coles Counties, Ill. (See Decatur sheet of maps of United States published by Army Map Service, scale 1:250,000 and Geological Survey quadrangle maps, scale 1:62,500.) Existing project. Provides for construction of a compacted earthfill dam with a concrete spillway section. Spillway structure will consist of an ogee overflow section surmounted by three 45- by 37-foot tainter gates. Dam will be about 108 feet above streambed and about 3,000 feet long. Relocations or alterations are required to railroads, highways, and miscellaneous utilities. Maximum storage capacity will be 684,000 acre-feet. Total project cost (1970) is $59,200,000, of which $12,290,000 is for lands and damages. Local contribution toward cost of project is $16,400,000. Local cooperation. Local interests must contribute toward cost of this project 7.06 percent of total cost for water-supply benefits provided, 6.86 percent of total cost for land enhancement, and 9.65 percent of total cost plus 5.75 percent of total cost of Carlyle Lake for recreation, fish and wildlife benefits. A contract was entered into between State of Illinois and the United States under which the State will act as local sponsor to make contributions for this project. State of Illinois is currently making payments thereunder. Operations and results during fiscal year. Planning and design and land acquisition continued. Construction was continued on relocations of roads, railroads, and utilities, reservoir clearing, main dam, and recreation facilities. Maintenance: Hired labor forces performed operation and maintenance of Lake Shelbyville. Condition at end of fiscal year. Project is 78 percent complete. Lands acquired to date are 34,305 acres in fee and 6,045 acres in easements. 8C. VILLAGE OF NEW ATHENS, ILL. Location. New Athens is in St. Clair County, Ill., on Kaskaskia River at mile 41. Existing project. Provides for construction of 6,875 feet of earth levee, a pumping station, drainage structures, and necessary closure structures and sewer alterations. Project cost is $1,928,000. Operations and results during fiscal year. Costs incurred were for operation and maintenance during construction. Condition at end offiscalyear. Project is complete. 8D.

Condition and operation studies, inspections and reports, real estate activities and project condition surveys cost $1,644. Reference line piles were installed. (See Table 15-H for dredging operations.) Condition at end of fiscal year. Existing project is complete except for portion deferred for restudy. Channel was complete to project dimensions from Houston Ship Channel to first bend in Cedar Bayou above the mouth in 1931. (See Table 15-E total cost of existing project to June 30, 1970.) 4. CLEAR CREEK AND CLEAR LAKE, TEX. Location. Clear Creek has its source about 13 miles south of Houston, Tex., and flows southeast for about 25 miles, emptying into west side of upper Galveston Bay at a point 24 miles northwest of Galveston, Tex. (See Coast and Geodetic Survey Chart 1282.) Existing project. (See Table 15-F for existing project dimensions provided for in this waterway.) Under ordinary conditions mean tidal range is about 0.8 foot and extreme range is 1.4 feet. Height of tides is dependent largely on the wind and during strong "northers" in winter season, water surface may be depressed 2 feet below mean low tide. (See Table 15-B for authorizing legislation.) Local cooperation. Fully complied with. Terminal facilities. Consist of small privately owned wharves, several ship repair yards and marinas which accommodate light commercial vessels and pleasure yachts. These are along lake shore and at towns of Seabrook and Kemah at mouth of creek. A commercial shell loading dock is located near League City at the head of the project. Operations and results during fiscal year. Maintenance: Engineering and design and supervision and administration cost $1,536 and $1,197. Condition and operation studies, inspections and reports, real estate activities and project condition surveys cost $2,257. Waterway information signs cost $288. Condition at end of fiscal year. Project was completed June 1950. 5. CORPUS CHRISTI SHIP CHANNEL, TEX. Location. This project, formerly known as the Port Aransas-Corpus Christi Waterway, Tex., was changed to Corpus Christi Ship Channel, Tex. by 1968 River and Harbor Act. This is a consolidation of old improvements of Port Aransas, Tex., and channel from Aransas Pass to Corpus Christi, Tex. Aransas Pass is on southern portion of Texas Coast, 180 miles southwest of Galveston and 132 miles north of mouth of Rio Grande. Aransas Pass connects Corpus Christi Bay and Aransas Bay with the gulf. Waterway extends from deep water in the gulf through Aransas Pass jettied entrance, thence westerly 20.75 miles to and including a turning basin at Corpus Christi, thence westerly 1.75 miles through Industrial Canal to and including turning basin at Avery Point, thence westerly 4.25 miles to and including a turning basin near Tule Lake, thence northwesterly 1.8 miles to and including a turning basin at Viola, Tex. (See Coast and Geodetic Survey Charts 523, 892, 893, 1285 and 1286.) Previous Project. For details see page 1861 of Annual Report for 1915. Existing project. (See Table 15-F for existing project dimensions provided for in various channels and basins comprising this waterway.) Project also provides for two rubblestone jetties at Aransas Pass entrance, extending into the gulf from St. Joseph and Mustang Islands, project lengths of which are 11,190 and 8,610 feet, respectively. Project further provides for a stone dike on St. Joseph Island about 20,991 feet long, connecting with north jetty and extending up this island to prevent a channel being cut around jetty. Under ordinary conditions, mean tidal range at Aransas Pass is about 1.1 feet and extreme range about 2 feet, and at Corpus Christi mean range about 1 foot and extreme about 1.5 feet. Heights of tides are dependent largely on strength and directions of winds, and during strong "northers" in the winter season water surface may be depressed as much as 3 feet below mean low tide. Estimated cost for new work is: Federal (Corps) $39,268,000, exclusive of amount expended on previous projects; and non-Federal $9,247,300, including $3,118,072 contributed funds and value of useful work performed, $1,289,228 lands, $2,855,000 relocations and $1,985,000 other costs.

ALBUQUERQUE DIVERSION CHANNELS PROJECT, NEW MEXICO Location. In area which comprises watersheds of ephemeral streams entering a 15-mile reach of Rio Grande from the east at Albuquerque, N. Mex., and vicinity. Combined drainage area of tributaries is about 276 square miles. Sandia Range of the Rocky Mountains, which is about 12 miles east of Rio Grande, forms eastern border of watersheds. Crest of mountain range rises more than a mile above river to an elevation of 10,692 feet above mean sea level. (See Geological Survey Map, Albuquerque, N. Mex., quadrangle, scale 1:62,500.) Existing project. There is a serious flood problem on tributaries of Rio Grande from east in Bernalillo County, Albuquerque, N. Mex., and vicinity. Small detention dams, constructed by city on several of these tributary arroyos, are not adequate to control floods. * All cost and financial statements for projects are listed at the appear at the end of this chapter. Flash floods originating on steep slopes of Sandia Mountains inundate large portions of highly developed lowlands area adjacent to river. Central business district, mainland and division shops of Atchison, Topeka & Santa Fe Railway, Federal and State highways, and commercial, industrial, residential, and suburban properties in lowlands are subject to flood damages. Plan of improvement consists of north and south diversion channels on high ground east of and parallel to valley. Channels are designed to carry floods equal in magnitude to standard project flood from all tributaries. Estimated Federal cost is $17,500,000. Estimated non-Federal cost, including required cash contribution of $530,000 is $11,060,000. Lands and damages costs are responsibility of local interests. (See Table 17-B for authorizing legislation.) Local cooperation. In addition to usual requirements, local interests must alter existing improvements, other than railroads, and prevent further encroachment end of this chapter. All other tables are referenced in text and also 533 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 upon existing defined waterways of tributaries by zoning or other means, or construct adequate waterways, or provide other drainage facilities to prevent flood problems in heights area of Albuquerque from developing into one of serious proportions. Local cooperation requirements also include cash contribution toward cost of construction in lump sum amounts equivalent to about 1.3 percent of total first cost of north diversion channel and about 3.4 percent of total first cost of south diversion channel. Total estimated cost to local interests, including cash contribution toward cost of construction is $11,060,000. Preconstruction planning was initiated in 1956. Work was stopped in fiscal year 1959 as a result of failure of local interests to comply with requirements. On November 21, 1958, 5-year notice of expiration of project authorization was issued to local interests. By act of State Legislature of New Mexico in 1963, Albuquerque Metropolitan Arroyo Flood Control Authority was created to provide local sponsorship for project subject to election of Board of Directors and approval of bond issue to provide funds for the authority. On August 27, 1963, voters approved a $9.5 million bond issue for funding necessary local cooperation costs and elected a board of directors to serve as its governing body. Formal assurances were accepted by district on November 19, 1963. An additional bond issue to cover increase in non-Federal cost was approved by voters in general election November 8, 1966. Operation and results during fiscal year. Construction of AT&SF Railroad main line crossing on south diversion channel was completed July 22, 1969. Construction of phase 1 of the south diversion channel, including relocation of Sandia Base (AEC) spur bridge and Kirtland AFB and Industrial Park spur tracks, was started March 2, 1970. Planning work on phase 2 of the south diversion channel was continued. Condition at end of fiscal year. Project planning is approximately 98 percent complete. Construction of the north channel is complete. Construction of the south channel is about 11 percent complete. Entire project is about 75 percent complete. 2. CONCHAS LAKE, CANADIAN RIVER, N. MEX. Location. Dam is in San Miguel County, N. Mex., on Canadian River, about one-fourth mile downstream from confluence of Canadian and Conchas Rivers. It is about 30 miles northwest of Tucumcari, N. Mex., and 743 miles upstream from mouth of Canadian River. Canadian River is about 906 miles long, rises in northeastern part of New Mexico, and flows south and east to Arkansas River near Webbers Falls, Okla. (See Geological Survey State map of New Mexico, scale 1:500,000, and Geological Survey topographic map, Tucumcari quadrangle, scale 1:125,000.) Existing project. A concrete gravity main dam section 1,250 feet long with a maximum height of 200 feet above streambed located in Canadian River Canyon together with earth dikes on each side having an overall length of about 3.7 miles. Main section contains conduits in its base for release of water to maintain low flows and for drainage of reservoir, and an overflow, ungated spillway 300 feet long. Earth dikes vary in height up to 100 feet and north dike contains a concrete ogee-type emergency spillway 3,000 feet long. Reservoir has a gross storage capacity of 550,800 acre-feet (198,200 for flood control, 273,000 for water conservation and irrigation, and 79,600 dead storage). Dam controls 7,409 square miles of drainage area. Federal cost was $15,811,171, including $2,279,326 for initiating construction of project under authority of Emergency Relief Appropriation Act of 1935. (See Table 17-B for authorizing legislation.) Local cooperation. None required. Operations and results during fiscal year. Operation of reservoir continued. Reservoir was operated for storage of floodwaters and releases for irrigation purposes. Estimated total accumulated flood damages prevented by project through fiscal year 1969 were $248,000. Estimated irrigation benefits for fiscal year 1969 were $235,200. Estimated total accumulated irrigation benefits through fiscal year 1969 were $5,312,847. Pool elevation at start of fiscal year was 4,187.80 feet, with corresponding storage of 240,484 acre-feet. Maximum pool elevation of 4,197.55 feet, with corresponding storage of 319,966 acre-feet, occurred April 23, 1970. Pool elevation did not exceed spillway crest (elevation 4,201 feet) during fiscal year. Irrigation releases were terminated October 16, 1969, and spring irrigation releases began March 17, 1970. Total releases for fiscal year were 90,276 acre-feet (89,096 for irrigation, and 1, 180 miscellaneous losses). Releases of 86,878 acre-feet were made to Arch Hurley Conservancy District and 2, 218 to Bell Ranch. Pool elevation on June 30, 1970, was 4,193.18 feet with corresponding storage of 282,121 acre-feet. Condition at end of fiscal year. Existing project was essentially complete in 1940. Reservoir and appurtenances are in good condition and in operation. Irrigation of some lands under project was begun in November 1945. 3. DODGE CITY LOCAL PROTECTION PROJECT, KANSAS Location. At Dodge City, Ford County, Kans., on Arkansas River about 130 miles downstream from Colorado-Kansas State line. (See Geological Survey map for Dodge quadrangle, scale 1:125,000.) Existing project. About 7 miles of levees of about 8.3 feet average height on both banks of Arkansas River (4.3 miles on left bank and 2.6 miles on right bank) and enlargement of river channel to form a floodway about 470 feet wide which will convey a flow of 40,000 cubic feet per second through city. Levees will be protected by flexible-type steel jetties. Four reaches of floodwalls about 100 feet long will be provided to insure continuity between levees and bridge abutments. Project also includes relocation of a railroad bridge and 534 ALBUQUERQUE, N. MEX., DISTRICT grade raise. Appurtenant works include interior drainage structures and fencing, a pumping plant for disposal of sanitary sewage during high water periods, and minor alterations to local roads and a sanitary sewerline. As result of the very damaging flood of June 1965 on the Arkansas River, which peaked at about 82, 000 c.f.s. at Dodge City, consideration was given to modification of project design to increase protection to maximum extent practicable without causing substantial increase in Federal and non-Federal costs. Plan adopted is based on a design flow of 40,000 c.f.s. with the added requirement that top of levees would not be lower than the profile for 60,000 c.f.s. flow. Revised frequency curves prepared since 1965 flood indicate 40, 000 c.f.s. flow would occur about once in 63 years and 82,000 c.f.s. flow about once in 250 years. These frequency curves also show that a 90-year frequency has a discharge of about 48,000 c.f.s., and it has been determined such a flow could be safely passed through the floodway as presently designed. The raise in top of levee to 60,000 c.f.s. profile would increase carrying capacity of floodway, but under such a plan the bridges on Second Street and 14th Avenue would not be raised. Sandbagging of the bridge crossings would be required during floods of that magnitude. Estimated Federal cost is $3,100,000. Cost of lands and damages is responsibility of local interests. (See Table 17-B for authorizing legislation.) Local cooperation. In addition to usual requirements, local interests must acquire easement for flood-zoning purposes in areas that would be used for ponding of interior drainage waters and hold United States free from claims as a result of flooding from residual interior drainage during operation of project; alter existing improvements, other than railroads, including provision of a sewage disposal pumping plant; inform all individuals concerned about residual flooding problem involved owing to temporary ponding; and provide assurances that encroachment on improved river channels, interior drains, and ponding areas will not be permitted; and if ponding areas and capacities are impaired, provide substitute storage capacity or equivalent pumping capacity. A bond issue for flood control purposes "in an amount not to exceed $700, 000" was approved by the voters October 12, 1965. Formal assurances were received March 25, 1970. Estimated non-Federal cost is $710,000. Operations and results during fiscal year. Preconstruction planning was continued. Design of the railroad bridge relocation was initiated under a cost reimbursable contract on June 30, 1970. Condition at end offiscalyear. Preconstruction planning is about 91 percent complete. The hydrology design memorandum and revised general design memorandum are complete. 4. EL PASO LOCAL PROTECTION PROJECT, TEXAS Location. At El Paso, El Paso County, Tex., which is on left bank of Rio Grande in reach that forms part of international boundary between United States and Republic of Mexico. (Geological Survey map for El Paso, Tex.; New Mexico quadrangle, scale 1:250,000.) Existing project. Consists of a single-purpose flood control system of detention dams, diversion dikes, and channels to collect, regulate, and discharge arroyo runoff into Rio Grande. Runoff from tributary arroyos on eastern, southern, and western slopes of adjacent Franklin Mountains often inundates sections of city and its outlying suburban developments. Project is divided into four independent elements: Northwest area, Central area, and two units (Copper System and Bluff Channel) in Southeast area. Improvements for Central area and Copper System of Southeast area are authorized for construction as soon as practicable, whereas construction of remainder of project (Northwest area and Bluff Channel of Southeast area) is to be deferred until construction is initiated by International Boundary and Water Commission on improvements which may be required to increase capacity of Rio Grande and its floodway. Elements authorized for construction as soon as practicable consist of seven reservoirs plus diversion and outlet channels in Central area to operate in conjunction with existing facilities and two reservoirs together with diversions and an outfall channel in Copper System of Southeast area. Deferred elements include three reservoirs and a diversion channel with appurtenances in Northwest area and Bluff Channel in Southeast area to intercept arroyo flows above area of principal damage and convey them to Rio Grande. Estimated Federal cost is $17,600,000. (See Table 17-B for authorizing legislation.) Authorized plans of improvement as recommended in survey report for Northwest area and Southeast area (Bluff Channel) would change flow conditions in Rio Grande through reach which forms part of international boundary between United States and Mexico. Proposed flood control project would collect and divert interior runoff which now ponds on valley floor and which would be discharged into this reach of river. Recommended plan was authorized subject to review and analysis of need for levee enlargement and channel improvement on Rio Grande by IB & WC. IB & WC has determined that it is not feasible to increase discharges into river as proposed in recommended plan and has stated that it would not serve best interests of United States to undertake necessary levee enlargement and channel improvements involved on Rio Grande. Instead, IB & WC recommends adoption of Plan B for the Northwest area as presented in survey report, which calls for four additional dams and minimum diversion channel work but which would cost about $4,000,000 additional. Boundary Commission would justify this plan by supporting additional costs. For Southeast area it recommends Plan C as presented in survey report which would substitute two dams for Bluff Channel at no extra cost over authorized plan. 535 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Local cooperation. In addition to usual requirements, local interests must alter existing improvements, other than railroads or improvements constructed and maintained by United States, prevent encroachment on all of project works which would reduce their design capacities; take steps to prevent encroachment upon existing defined waterways tributary to project by zoning or other means such as enlargements, or other modifications, of existing waterway facilities to prevent minor flood problems in these tributary waterways from developing into problems of serious proportions; and inform all concerned that project is designed to control floods originating above structures and that some residual flooding may be expected from precipitation occurring below structures. Estimated non- Federal cost is $3,800,000. Operations and results during fiscal year. Preconstruction planning of Central area and Copper System of Southeast area was continued. Plans and specifications for a portion of Fort Bliss Sump and Mountain Avenue Outlet Conduit were completed during the fiscal year. Condition at end of fiscal year. Preconstruction planning is about 95 percent complete. 5. GREAT BEND LOCAL PROTECTION PROJECT, KANSAS Location. At Great Bend, Barton County, Kans., on left bank of Arkansas River at river mile 873, about 4.5 miles upstream from confluence of Walnut Creek with Arkansas River. (See Geological Survey map, Great Bend quadrangle, scale 1:250,000.) Existing project. Consists of 6.2 miles of leveed channel to divert Walnut Creek floodflows around and upstream from city into Arkansas River; a leveed channel 1.5 miles long to direct Little Walnut Creek floodflows into Walnut Diversion Channel; 6 miles of improved channel with levees along Arkansas River; a tieback levee 4.3 miles long on left bank of Arkansas River upstream from junction with Walnut Diversion Channel; alteration or relocation of two railroad bridges; and appurtenant facilities. Project will protect city of Great Bend and vicinity from Arkansas River flows up to 86,000 cubic feet per second and Walnut Creek flows of 26,000 cubic feet per second. Estimated Federal cost is $5,880,000. (See Table 17-B for authorizing legislation.) Local cooperation. In addition to usual requirements, local interests must provide easements for flood zoning purposes in ponding areas; hold United States free from claims as a result of flooding from residual interior runoff during operation of project; inform periodically all concerned that some flooding will continue to occur because of temporary ponding; prohibit any encroachment on design capacities of river channel, diversion channels, interior drains, and ponding areas; and if ponding area capacities are impaired, provide promptly, without cost to United States, substitute storage or equivalent pumping capacity; alter existing improvements, other than railroad bridges and approaches connected therewith; provide fences on both sides of Walnut diversion channel for structural protection and as a safety measure during periods of high flow. In addition, construction of the flood control works will be initiated concurrently with or subsequent to replacement of U.S. Highway 281 bridge across Arkansas River. A bond issue to finance requirements was defeated in special election on August 10, 1965. Since defeat of initial bond issue, City Council initiated a campaign to better acquaint people in community with proposed project. On April 2, 1968, a bond issue was again defeated. Governing Body of Great Bend is proceeding with further studies and hopes to again present bond issue to the people. Estimated non- Federal cost is $2,090,000. Operation and results during fiscal year. Project planning has been held in abeyance since defeat of bond issue. Condition at end of fiscal year. Preconstruction is about 2 percent complete. 6. JOHN MARTIN RESERVOIR, ARKANSAS RIVER, COLO. Location. On Arkansas River 1, 159 miles upstream from its mouth, 300 miles downstream from its source, in Bent County, about 18 miles upstream from city of Lamar, Colo. (See Geological Survey maps for Lamar and Las Animas (Colo.) quadrangles, scale 1:125,000.) Existing project. A concrete and earthfill structure about 2.6 miles long with a maximum height of 130 feet above streambed and an overflow, gated spillway 1,174 feet long. On basis of sediment resurvey, new areacapacity curves show reservoir storage capacity of 618, 700 acre-feet (261,000 for flood control and 357,700 for conservation and recreation storage). Reservoir controls a drainage area of 18,915 square miles and is operated as a unit of coordinated reservoir system for flood control in Arkansas River Basin. Federal cost was $15,173,389. (See Table 17-B for authorizing legislation.) Public Law 89-298 modified the act of June 22, 1936 (49 Stat. 1570) to authorize and direct Chief of Engineers to use, not to exceed, 10,000 acre-feet of reservoir flood control storage space for fish and wildlife and recreation purposes. The Chief of Engineers provided this space and set top elevation of conservation, fish and wildlife and recreation pool at elevation 3,851.83 feet contingent upon stipulations and limitations of said act. Local cooperation. Section 2, Flood Control Act of June 28, 1938, applies. Operations and results during fiscal year. Ordinary maintenance and operation continued. Regulation of conservation storage continued under rules and regulations of Arkansas River Compact. Estimated flood and sediment damages prevented during fiscal year 1969 were $209,440. Estimated total flood and sediment damages prevented by project through fiscal year 1969 were $72,380,000. Estimated irrigation benefits for fiscal year 1969 were $1,105,800. Estimated total accumulative irrigation benefits through fiscal year 1969 were $18,563,729. Maximum pool elevation of 3810.88 feet with corresponding storage of 57,852 536 ALBUQUERQUE, N. MEX., DISTRICT acre-feet occurred on April 19, 1970. Total releases for fiscal year were 181,516 acre-feet (181,464 for irrigation and 52 unidentified losses). Releases attributed to irrigation benefits amounted to 85,527 acre-feet. Reservoir was empty from July 13-17, 1969; July 27- Aug. 21, 1969; Sept. 1-7, 1969; and May 28-June 30, 197,0. Winter storage was in effect from November 1 until April 10. Condition at end of fiscal year. Storage and operation of reservoir for irrigation began in March 1943. Construction of dam and appurtenances was completed in October 1948 and are in good condition and in operation. 7. LAS ANIMAS LOCAL PROTECTION PROJECT, COLO. Location. At Las Animas, Bent County, Colo., at river mile 1,175 on Arkansas River, just upstream from its confluence with Purgatoire River, a major tributary that enters Arkansas River from south. (See Geological Survey map, Lamar, Colo.; Kans. quadrangle, scale 1:250,000.) Existing project. Consists of a levee 9.6 miles long on south bank of Arkansas River and a levee about 1 mile long on north bank. Appurtenant works include levee protection measures; an interior drainage system consisting of outlet structures, a ditch, and ponding areas; and intake structures for irrigation canals. Design flood is 140,000 cubic feet per second, which is equivalent to flood of record (June 1921 flood with peak discharge of 187,000 cubic feet per second, reduced by regulatory effect of Barrier Dam, near Pueblo, Colo., which was placed in operation shortly after June 1921 flood). Estimated Federal cost is $2, 280,000. (See Table 17-B for authorizing legislation.) Local cooperation. In addition to usual requirements, local interests must at least annually inform individuals concerned about residual flood problem involved owing to temporary ponding; prevent encroachment on river channel, which would reduce design flow capacity through leveed section and on ponding areas and interior drains; and if ponding area is impaired, provide substitute storage or equivalent pumping capacity promptly without cost to United States; and alter existing improvements, other than railroad bridges and approaches in connection therewith. In addition, construction will begin concurrent with or subsequent to replacement of United States Highway 50 bridge across Arkansas River; and in event local interests desire to create planned fishing lake at time Federal project is constructed, they must contribute cost of excavating fishing lake in excess of cost of borrow material from least costly alternative source currently estimated at $33,000, and hold United States free from water rights claims. Construction of U.S. Highway 50 bridge across Arkansas River has been completed. Inasmuch as the flood control project extends beyond the corporate city limits of Las Animas, Colorado, the Arkansas River Conservancy District, Las Animas, Colorado, a political subdivision duly constituted and organized under the laws of the State of Colorado, is the sponsoring agency which will furnish required local cooperation. Conservancy District has jurisdiction and power to levy taxes both in the city and in those areas outside city limits affected by the project. Prior to authorization of project, the Conservancy District pledged in writing that it favored project and would furnish required local cooperation. Estimated non-Federal cost is $280,000. Operations and results during fiscal year. Preconstruction planning was continued. Condition at end of fiscal year. Preconstruction planning is about 90 percent complete. 8. LAS CRUCES LOCAL PROTECTION PROJECT, NEW MEXICO Location. On tributaries of Rio Grande at Las Cruces, Dona Ana County, N. Mex., about 87 miles downstream from Elephant Butte Dam. (See Geological Survey Map for Las Cruces, N. Mex., quadrangle, scale 1:62,500.) Existing project. Consists of two dams, Las Cruces Dam, which extends across Alameda and Las Cruces Arroyos, and Campus Dam, on Campus Arroyo. Both will be provided with uncontrolled outlets and spillways. Las Cruces Dam, about 1,000 feet east of Las Cruces city limits, will be earthfill construction about 15,570 feet long and 67 feet high with both slopes protected. Discharges from dam will be conveyed downstream in channel of Alameda Arroyo for about 10,968 feet and then by means of an unlined, trapezoidal channel for about 13,910 feet to Rio Grande. Reservoir capacity is 13,200 acre-feet at maximum water surface and 8,200 acre-feet at spillway crest. Controlled drainage area is 28.9 square miles. Campus Dam will be a small earthfill structure 1,790 feet long and 34 feet high located on Campus Arroyo immediately upstream from campus of State University. Both slopes will be protected by 6-inch layer of spalls. Flows from dam will be discharged directly into channel of Campus Arroyo. Reservoir capacity is 190 acre-feet at maximum water surface elevation and 158 acre-feet at spillway crest. Controlled drainage area is 0.45 square miles. Estimated Federal cost is $4, 970,000. (See Table 17-B for authorizing legislation.) Local cooperation. In addition to usual requirements, local interests must alter existing improvements, other than railroads; prevent encroachment upon outlet channel from Las Cruces Dam to Rio Grande in order to maintain a channel capacity of 275 cubic feet per second; prevent encroachment upon existing channel of Campus Arroyo from Campus Dam to point opposite present location of university sewage disposal plant in order to maintain a channel capacity of at least 30 cubic feet per second through this reach; and prevent encroachment, other than natural sediment deposits, on the reservoir areas which would reduce their storage capacities. Estimated non-Federal cost is $1,280,000. Formal request for assurances was trans- 537 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 mitted to city of Las Cruces by letter dated December 3, 1965, which constituted formal notification of commencement of 5-year period of project authorization during which time local interests must fulfill requirements of local cooperation. City has cash resources of $536,000 available from bond issue; however, that amount is insufficient to meet total estimated costs of local cooperation ($1,280,000). Las Cruces Metropolitan Arroyo Flood Control Authority, created to take over the requirement of local cooperation inasmuch as city had exhausted its bonding capability, was dissolved after defeat of bond issue on January 30, 1968. On February 20, 1968, Mayor of Las Cruces stated that city had resumed work on project and was actively pursuing matter of financing local cooperation requirements and would explore all possible sources of revenue and funding which could be developed. City used proceeds available from original bond issue ($536,000) to obtain possession and gain control of lands for Las Cruces Dam portion of project to head off further escalation of land prices. Operations and results during fiscal year. Planning suspended after notification bond issue failed to pass. Condition at end of fiscal year. Work on the project has been suspended. 9. LOS ESTEROS LAKE AND MODIFICATION OF ALAMOGORDO DAM, PECOS RIVER, N. MEX. Location. Los Esteros Lake is in Guadalupe County, on Pecos River, at river mile 766.4 approximately 7 miles north of Santa Rosa, N. Mex. Alamogordo Dam (existing) is in DeBaca County on Pecos River, at river mile 710.8 about 21 miles upstream from Fort Sumner, N. Mex., and about 29 miles southeast of Santa Rosa, N. Mex. (See U.S. Geological Survey map, Corazon, N. Mex.), sheet, scale 1:125,000.) Existing project. Authorized plan of improvement provides for construction of an earthfill dam 1,865 feet long with maximum height of 218 feet above streambed for flood control, irrigation, possible municipal water supply, and sediment storage. An uncontrolled spillway will be located about 1,000 feet back from left abutment and will be an unlined, open rock cut. Outlet works, composed of a combination pressure tunnel and penstock with two 54-inch diameter balanced, free discharge valves will be located under left abutment. An earthfill saddle dam 1, 420 feet long and 12-foot maximum height will be located 4,000 feet back from left abutment of main dam. Storage capacity of reservoir at spillway crest is 505,400 acre-feet, of which 60,000 acre-feet is allocated to sedimentation reserve, 200,000 acre-feet to irrigation and water supply, and 245,400 acre-feet to flood control. Area of reservoir at spillway crest is 11,830 acres. Dam controls 2,479 square miles of drainage area. Authorized project also includes modification of existing Alamogordo Dam and Reservoir on Pecos River (river mile 710.8) about 21 miles upstream from Fort Sumner, N. Mex., to exclusive flood-control use. Under the terms of Pecos River compact and with consent of Carlsbad Irrigation District, irrigation storage from Alamogordo Reservoir will be transferred to Los Esteros Lake. Existing dam is an earth and rockfill structure composed of two sections: main dam and a dike section which extends from main dam to left abutment. Main dam is 148 in height and there is a 3- foot parapet wall on crest of dam. Concrete chute spillway controlled by three tainter gates is located in right abutment. Small hydroelectric plant, with a capacity of 7.5 kv-a., supplies local power requirements at dam. Reservoir is about 14 miles long, and has a capacity of about 128,000 acre-feet, considering most recent estimate of displacement by sediment. To effect change of Alamogordo Reservoir to exclusive flood-control use, embankment will be raised 10.5 feet and an emergency spillway 500 feet long will be cut through sandstone and shale ridge on the right abutment. Because maximum water surface would be higher under modified condition, crest of service spillway will be raised to limit discharge to existing capacity of chute. Tainter gates and piers will be removed. Also needle valves on outlet works will be removed. Modified reservoir will have capacity at spillway crest of 168,100 acre-feet. Area of reservoir at spillway crest will be 5,960 acres. Storage capacity of Alamogordo Reservoir is diminishing annually at rate of about 2,200 acre-feet by sedimentation and if operated under existing conditions will not be capable of supplying the full irrigation demand of Carlsbad Irrigation District for more than 40 years. With reservoir operated exclusively for flood control in combination with Los Esteros Dam, appreciable amount of the sediment from intervening area will be sluiced through, and therefore it is estimated that deposition of sediment will be reduced to an average of about 460 acre-feet annually. With reduced rates of sediment deposition and with proposed modification to the dam and spillway, the Alamogordo Reservoir will be effective for flood control for 100 years. Modifications of Alamogordo Dam already completed by United States Bureau of Reclamation consist of raising dam to required height, modifying service spillway for proper functioning due to increased height of dam, and construction of emergency spillway. Preliminary studies by Corps indicate some minor changes in modified service and emergency spillways may still be necessary to adequately comply with requirements of authorized project for flood control and irrigation. Modifications of dam completed by U.S. Bureau of Reclamation have greatly increased spillway capacity and will have effect of greatly reducing cost of the project to Corps. Full extent of reduction in cost, however, will not be known until general design studies are completed. Federal cost is $13,500,000 for Los Esteros Lake, and $1,000,000 for modification of Alamogordo Dam 538 ALBUQUERQUE, N. MEX., DISTRICT including work completed by USBR, a total of $14,500, 000. (See Table 17-B for authorizing legislation.) Local cooperation. In addition to first costs, operation and maintenance of both reservoirs will be responsibility of Federal Government; however, Carlsbad Irrigation District will be required to contribute to operation and maintenance costs an annual amount equal to what they now pay toward Alamogordo Dam. Carlsbad Irrigation District also will be required to agree to use of Alamogordo Reservoir for flood-control purposes, and because they will realize equivalent benefits from storage capacity in Los Esteros Lake, they will be required to continue to fulfill their repayment obligation. Project was authorized subject to the provision that "no appropriation shall be made for construction of Los Esteros Lake until satisfactory arrangements have been made by the State of New Mexico for the transfer of irrigation storage from the Alamogordo Reservoir." Engineer advisors to Pecos River Compact Commission have completed water studies to determine the effects of project on water supply in Pecos River basin. Corps, U.S. Bureau of Reclamation, Carlsbad Irrigation District, and engineer advisors to Texas and New Mexico commissioners participated in studies. Completed studies have been approved and accepted by Pecos River Compact Commission and State Engineer of New Mexico. Compact Commission has under consideration administration procedures proposed by State Engineer of New Mexico for approval prior to final negotiations with Carlsbad Irrigation District to complete arrangements for the transfer of irrigation storage. Operations and results during fiscal year. Preconstruction planning continued. General design memorandum wa.s submitted for approval Jan. 30, 1970. Plans and specifications for access road were started. Condition at end of fiscalyear. Preconstruction planning is about 87 percent complete. 10. RIO GRANDE BASIN, N. MEX. Location. Improvements are on Rio Grande and tributaries in New Mexico. More definite locations and descriptions of individual projects are in following paragraphs and individual reports by projects. Existing project. Flood Control Act of 1948 authorized flood control phase of comprehensive plan of development of water resources of Rio Grande basin in New Mexico (H. Doc. 243, 81st Cong., 1st sess.) with exception of Chiflo Dam and Reservoir and spillway gate structure at Chamita Dam. Although recommended Chiflo Dam and Reservoir was deleted from authorized plan, it was excluded without prejudice to future consideration by Congress. It was requested at that time, by States of Colorado and Texas, that project be deferred for restudy regarding required storage and methods of operation. By same act, Congress also authorized for construction irrigation phase of comprehensive plan as recommended by Bureau of Reclamation (H. Doc. 653, 81st Cong., 2d sess.). The act also stipulated that work should be prosecuted in accordance with joint agreement approved by Secretary of the Army and Acting Secretary of the Interior on November 21, 1957. In addition, under that agreement Bureau of Reclamation was given responsibility for construction, operation, and maintenance of channel rectification, and drainage rehabilitation and extension phases of unified plan of improvement. Authority for Chamita Dam and Reservoir was abrogated when Cochiti Dam and Reservoir was authorized. (See Table 17-B for authorizing legislation and Table 17-D for existing projects.) All operations and costs for projects in authorized plan are in individual reports on the following pages. 10A. ABIQUIU DAM, RIO CHAMA, N. MEX. Location. Project is one unit of flood control phase of comprehensive plan for Rio Grande and tributaries, New Mexico. Abiquiu Dam is on Rio Chama near town of Abiquiu, N. Mex., about 30 miles upstream from confluence of Rio Chama and Rio Grande. (See Geological Survey Map for plan and profile of Rio Chama, N. Mex., from mouth to mile 103, sheet 1, and Army Map Service, Aztec, N. Mex.; Colorado NJ 13- 10, scale 1:250,000.) Existing project. An earthfill dam 1,540 feet long, rising 325 feet about streambed, with a 12-foot diameter controlled outlet, and an uncontrolled spillway in a natural saddle about 1 mile north of left abutment. Reservoir provides 571,000 acre-feet of flood control and sediment storage. Total capacity at spillway crest is 1,217,300 acre-feet. (See table 17-B for authorizing legislation.) Operations and results during fiscal year. Ordinary maintenance and operation continued. Storage and flows were regulated in accordance with regulations prescribed by Rio Grande Compact Commission. On July 1, 1969, pool elevation was 6,103.96 with corresponding storage of 2,662 acre-feet. Storage varied from about 1,900 acre-feet to 4,400 acre-feet during the period from July 1, to December 31, 1969. Releases of El Vado Dam storage were passed through Abiquiu Reservoir from November 19 to December 19, 1969. Maximum pool elevation of 6,166.98 with corresponding storage of 48,700 acre-feet occurred on May 25, 1970. The permanent pool of approximately 2,000 acre-feet was maintained and inflow was released from January 1 to May 10 except for the period from February 13 to March 3 when the pool was drawn down to permit conduit and gate inspection. On May 10, 1970, the New Mexico State Engineer requested releases be reduced to 500 c.f.s. due to levee erosion near Chili. Large snowmelt flows began on Rio Ojo Caliente below Abiquiu Dam during the last week in April which deposited considerable sediment in the Rio Chama Channel near Chili, and the channel levee was breached. On May 13 releases from the reservoir were increased to 800 c.f.s. and as the channel continued to degrade releases were further increased. Maximum release of 2,350 c.f.s. occurred on June 12, 1970. By 539 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 June 15, 1970, storage was drawn down to permanent pool level of about 2,000 acre-feet. Pool elevation was 6, 104.75 with corresponding storage of 2,020 acre-feet on June 30, 1970. Accumulated flood and sediment damages prevented by the project since completion were $643,750, through fiscal year 1969. Condition at end of fiscal year. Project was placed in operation in February 1963. 10B. COCHITI LAKE, N. MEX. Location. Dam is at river mile 340 on Rio Grande (river mile 0 being at intersection of New Mexico- Texas State line with international boundary at El Paso, Tex.), near village of Cochiti, which is about 50 miles upstream from Albuquerque, N. Mex. (See Geological Survey Maps, Cochiti Dam, N. Mex., Quadrangle and Santo Domingo Pueblo, N. Mex., quadrangle, scale 1:24,000.) Existing project. Consists of an earthfill dam about 5.1 miles long with a maximum height of 251 feet above streambed. Project will extend generally in an eastwest line across Rio Grande to a point about 2 miles east of Rio Grande and then southward across Santa Fe River. An uncontrolled spillway with a 460-foot-long ogee-weir and a 160-foot notch 10 feet deep in center will be at end of embankment on south side of Santa Fe River. Operational releases for flood control and irrigation will be made through a 3-barrel gated conduit in left abutment on Rio Grande. No outlet will be provided on Santa Fe River. Dead storage in Santa Fe River and Canada de Cochiti arms of reservoir will be eliminated by means of conveyance channels. Construction will also involve relocation of a gravelsurfaced Forest Service road and an irrigation headworks and canal. Reservoir will have a storage capacity of 442,000 acre-feet for flood control, 110,000 acre-feet for sediment, and 50,000 acre-feet for recreation a total of 602,000 acre-feet. Storage capacity for permanent pool for recreation will be provided by slightly modifying the operating procedures. Modification of project structures, except for specific recreation facilities, will not be necessary because of permanent pool. Estimated Federal cost is $85,500,000. (See table 17-B for authorizing legislation.) Operations and results during fiscal year. Construction of embankment and conveyance channels, portions of the outlet and spillway, phase 2 of road relocation, utilities and structures, some reservoir clearing, service road, overlook facilities and parking area was initiated June 19, 1970, under one contract. Construction of outlet works portion and relocation of portions of irrigation structures and utilities and New Mexico Highway 22 was continued. Conditions at end offiscalyear. Project planning is about 95 percent complete. Construction of the major portion of the spillway is complete. Construction of the outlet works (portion) and relocation of portions of irrigation structures and utilities and New Mexico Highway 22 is about 97 percent complete. Entire project is about 22 percent complete. 10C. GALISTEO DAM, N. MEX. Location. Dam is at river mile 12 on Galisteo Creek, a tributary of Rio Grande. Definite project site is about 8 miles upstream of project document site. Reservoir will extend upstream from dam for about 4 miles to near village of Waldo, N. Mex. (See Geological Survey Map, San Pedro 1, N. Mex. quadrangle scale 1:24, 000.) Existing project. Consists of an earthfill dam 2,820 feet long with a maximum height of 158 feet above streambed. There will be a 10-foot diameter uncontrolled outlet with discharge capacity of 4,980 cubic feet per second for pool at spillway crest elevation, and a spillway with a broad crested weir 250 feet long in right abutment. At spillway crest elevation reservoir will have a storage capacity of 89,800 acre-feet for flood control, in which provision is made for storage of 10,200 acre-feet of sediment based on an estimated 50-year sediment depletion. Santa Fe River which enters Rio Grande about 5 miles upstream from mouth of Galisteo Creek will be diverted into Cochiti Reservoir instead of Galisteo Reservoir as provided in project document plan (S. Doc. 94, 86th Cong., 2d sess.). Estimated Federal cost is $13,800,000. (See table 17-B for authorizing legislation.) Operations and results during fiscal year. Construction of the outlet works, embankment, spillway and other facilities was continued. Condition at end of fiscal year. Project planning, construction of access road, relocation of county road and A.T. & S.F. Railroad are complete. Construction of outlet works, embankment, spillway and other facilities is essentially complete. Entire project is about 98 percent complete. 10D. JEMEZ CANYON DAM, N. MEX. Location. In Sandoval County, N. Mex., on Jemez River about 2 miles upstream from confluence of Jemez River and Rio Grande, about 5 miles northwest of Bernalillo, N. Mex. (See Geological Survey Map for Bernalillo quadrangle, scale 1:125,000.) Existing project. An earthfill dam 780 feet long with a maximum height of 136 feet above streambed, and offchannel uncontrolled saddle spillway 400 feet wide, and a 13-foot diameter gated outlet in left abutment with discharge capacity of 8,100 cubic feet per second with pool at spillway crest elevation. Reservoir has a capacity of 117,213 acre-feet (73,000 acre-feet for flood control and 44,213 acre-feet for sediment control, in which 4,914 acre-feet of sediment have been deposited.) It is estimated that 70,000 acre-feet of storage will be available in the reservoir for flood control after 50 years of project life. Federal cost was $4,177,417. (See table 17-B for authorizing legislation.) 540 ALBUQUERQUE, N. MEX., DISTRICT Operations and results during fiscal year. Ordinary maintenance and operation continued. Reservoir was empty on July 1, 1969, and remained empty most of the year except for short periods of sediment control storage during August, September, and October, 1969. Sediment control regulation for spring runoff began on April 8, 1970, and continued until May 31, 1970. There was no flood control regulation for the fiscal year. The maximum pool elevation was 5,160.55 on October 23, 1969, with a corresponding storage of 3, 198 acre-feet. Estimated total accumulated flood and sediment damages prevented by project through fiscal year 1970 were $1,660,620. Condition at end of fiscal year. Construction of project was initiated May 1950 and completed May 1954. 10E. RIO GRANDE FLOODWAY, N. MEX. Location. Project is one unit of flood control phase of comprehensive plan of improvement for Rio Grande Basin in New Mexico. It is on Rio Grande and covers section of river commencing near Truth or Consequences (formerly Hot Springs) at about river mile 123 and extends upstream to lower end of Rio Grande Canyon about 14 miles upstream from Espanola, N. Mex., about river mile 394. (See table 17-D on Rio Grande Floodway.) Existing project. Consists of flood protection and major drainage improvements by channel rectification, levee enlargement and construction, and bank stabilization work where needed to protect levees. Construction of project is a joint undertaking by Bureau of Reclamation and the Corps. Portions to be done by Corps will consist of levee enlargement, construction, and bank protection work, with channel-rectification and drainage-rehabilitation work the responsibility of Bureau of Reclamation. Levees constructed by local interests exist through reach of river involved, but are not uniform as to grade, section, or standard of construction, and in many places are threatened by meandering river. (See table 17-E on existing project and table 17-B for authorizing legislation.) Local cooperation. In addition to usual requirements, local interests are responsible for all highway, bridge, and public utility relocations or replacements required in construction of project. Fully complied with for completed units of floodway. Total costs for all requirements for completed Albuquerque unit under terms of project authorization were $75,000. There were no non-Federal costs in connection with construction of Cochiti to Rio Puerco unit of floodway. Espanola Valley unit was inactive for several years; however, in December 1963, local interests reaffirmed need for flood protection for city of Espanola, and indicated in writing that they were willing and able to provide necessary rights-of-way for levees and make utility relocations required in construction of project. Project was reclassified to active category, and funds were appropriated for initiation of preconstruction 451-584 0-72-35 planning in fiscal year 1966. Progress on this project has been slow because the local sponsor was extremely dilatory in meeting the request for rights-of-entry in order to perform surveys. Right-of-entry was finally obtained on May 15, 1967, from the Indian Pueblo of Santa Clara which is the principal landowner affected by the project. Operations and results during fiscal year. Preconstruction planning for the Espanola Valley unit of the floodway was continued. Estimated total accumulated flood damages prevented by the floodway project through fiscal year 1969 amounted to $747,280. Condition at end of fiscal year. Construction of Albuquerque and Cochiti to Rio Puerco units of Rio Grande Floodway project is complete. San Acacia to Bosque del Apache and Truth or Consequences (Hot Springs) units of floodway are deferred for restudy. Hydrology and general design memoranda for Espanola Valley unit have been approved. Preconstruction planning is about 90 percent complete. 11. TRINIDAD LAKE, PURGATOIRE RIVER, COLO. Location. On Purgatoire River about 161 miles above its junction with Arkansas River. Project is about 4 miles upstream from city of Trinidad, Colo. (See Geological Survey Map, Trinidad, Colo., quadrangle, scale 1:24,000.) Existing project. Consists of an earthfill structure 6,610 feet long, with a maximum height of 200 feet above streambed, an uncontrolled spillway 1,000 feet wide in left abutment, and a 10-foot diameter, gate-controlled conduit in right abutment with discharge capacity of 4, 850 cubic feet per second with water surface at top of flood control pool. Reservoir provides for storage of 51, 000 acre-feet for flood control, 39,000 acre-feet for sediment, 20,000 acre-feet irrigation, and 4,500 acrefeet for recreation, a total of 114,500 acre-feet. Reservoir controls a drainage area of 606 square miles and will be operated for flood and sediment control, irrigation, and recreation purposes. Estimated Federal cost is $27,400,000 (CE) & $160,000 (USBR). (See table 17-B for authorizing legislation.) Local cooperation. Requirements based on approved general design memorandum studies: Repayment by Purgatoire River Water Conservancy District of first cost allocated to irrigation established as 29.28 percent of total project cost presently estimated at $8,023,000 (1970 prices) generally in accordance with Federal reclamation law procedures, except that repayment of irrigation first cost may extend over a period not to exceed 75 years including a 5-year development period which results in an actual amortization period of 70 years; contribution of $21,400 annually by State of Colorado for replacement of evaporation and seepage losses from permanent fishery pool; Purgatoire River Water Conservancy District (representing the ir- 41 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 rigators) is required to bear 19.82 percent of annual joint-use operation and maintenance costs and 2.52 percent of major replacement costs presently estimated at $13,600 annually; in addition, estimated annual cost to city of Trinidad for maintenance of channel of Purgatoire River through city is $1,100. In addition conservancy district must make arrangements for transfer of Model Land and Irrigation Co.'s storage rights from existing Model Reservoir to Trinidad Reservoir. Storage for recreation purposes not included in authorized project plan; however, project document noted that substantial benefits would be derived from such use and that there was strong local support for such storage. Provision was made in project plan for 4, 500 acre-feet of permanent storage for recreation; however, since flows of Purgatoire River are fully appropriated, water rights will have to be acquired by non-Federal interests. Estimated cost of initial filling of pool is $250,000 and replacement of evaporation losses will cost an estimated $21,400 per year. Lands and facilities for recreation will be provided at Federal expense, but cost of water rights will be borne by the State of Colorado. Assurances of local cooperation received from City of Trinidad and Purgatoire River Water Conservancy District were formally accepted May 11, 1967, after execution of irrigation repayment contract. Stipulated decree changing place of storage of water rights decreed to existing Model Reservoir from that reservoir to proposed Trinidad Reservoir was conditionally approved by Las Animas County, Colorado, District Court April 15, 1965, subject to ultimate execution and approval of irrigation repayment contract, which qualifying condition is now removed. Purgatoire River Water Conservancy District, representing water users, signed prime irrigation repayment contract January 21, 1967. Prime contract was then signed by Regional Director, Region 7, Bureau of Reclamation February 10, 1967, under delegated authority of U.S. Department of Interior. Contract is dated February 10, 1967. Irrigation repayment contract was confirmed by decree of Las Animas County, Colorado, District Court entered into March 21, 1967, and 30-day period of appeal required by Colorado statutes expired with no appeals being filed. Operations and results during fiscal year. Acquisition of real estate was continued. Construction of outlet works was continued. Revised assembly for cemetary relocation plan was approved. Preparation of plans and specifications on relocation of county road was continued. Condition at end of fiscalyear. Construction of outlet works is about 95 percent complete. Acquisition of land for project is about 81 percent complete. Entire project is about 23 percent complete. 12. TWO RIVERS DAM, N. MEX. Location. About 14 miles southwest of Roswell, N. Mex., on Rio Hondo. Rio Hondo is formed at confluence of Rio Ruidoso and Rio Bonito, near village of Hondo, N. Mex., in foothills region of Sierra Blanca in southeastern part of Lincoln County, N. Mex., and flows generally easterly to its confluence with Pecos River near Roswell, N. Mex. (See Geological Survey Map, Hondo Reservoir quadrangle, scale 1:24,000.) Existing project. Two earthfill dams, Diamond "A" Dam on Rio Hondo at about river mile 36 and Rocky Dam on Rocky Arroyo at about river mile 14, which will form Two Rivers Reservoir. Diamond "A" Dam is 98 feet high and 4,918 feet long and Rocky Dam is 118 feet high and 2,920 feet long. Topography of site permits use of two natural saddles in limestone on rim of reservoir for spillways which have a total length of 1, 130 feet. One of the spillway saddles is between the dams and one is south of Rocky Dam. There is a gated outlet works structure in Diamond "A" Dam and an uncontrolled outlet in Rocky Dam. No provision is made for storage except for flood control. Flood releases will be controlled insofar as possible, so that flows through Roswell will not exceed channel capacity of Rio Hondo, which is 1,000 cubic feet per second. Capacity of Two Rivers Reservoir at spillway crest is 168,000 acre-feet, of which 18,000 acre-feet are provided for sedimentation reserve, but which will be utilized for flood control until filled with sediment. Dam controls 963 square miles of drainage area on Rio Hondo and 64 square miles on Rocky Arroyo, a total of 1,027 square miles. Federal cost was $4,790,838. (See table 17-B for authorizing legislation.) Local cooperation. Complied with. Total cost to local interests was $144,000, of which $60,000 was for construction of access road and $84,000 for lands and rights-of-way. Operations and results during fiscal year. Ordinary maintenance and operation continued. Reservoir was empty July 1, 1969. No flood control regulation during the fiscal year. The peak mean daily inflow was 696 c.f.s. on September 21, 1969. Diamond "A" Dam had a maximum pool elevation of 3,982.70 feet with a corresponding storage of 849 acre-feet on September 21, 1969. Rocky Dam had a maximum pool elevation of 3,947.57 feet with a corresponding storage of 100 acre-feet on September 22, 1969. September was the only month during the fiscal year in which there was storage in Two Rivers Dam. Estimated total accumulated flood damages prevented through fiscal year 1969 were $1,074,910. Condition at end of fiscal year. Project is complete and was placed in operation July 1963. 542 ALBUQUERQUE, N. MEX., DISTRICT 13. INSPECTION OF COMPLETED FLOOD CONTROL PROJECTS Included under this heading is inspection of completed flood control projects transferred to local interest for operation and maintenance. Projects in Colorado and New Mexico were inspected. Fiscal year cost was $5,063 and total cost to June 30, 1970, was $40,930. 14. SCHEDULING FLOOD CONTROL RESERVOIR OPERATIONS Pursuant to section 7, Flood Control Act of 1944, expenditures were made for scheduling flood control reservoir operations and preparation of reservoir regulation manual for Platoro Dam on Conejos River near town of Platoro, Conejos County, Colo. Platoro Dam was authorized by Interior Appropriation Act of 1941 (see H. Doc. 693, 76th Cong., 3d sess.). Construction of project was completed by Bureau of Reclamation in fiscal year 1952. Reservoir elevation at start of fiscal year was 9,951.5 feet with corresponding storage of 5,600 acre-feet. There was no change in storage until November 1, 1969, when storage transfer to Elephant Butte Reservoir began. On November 7, 1969, the pool elevation was 9,942.3 with a corresponding storage of 3,000 acrefeet, and operation of Platoro Dam was closed for the winter. Operation began again on April 28, 1970. The pool elevation on that date was 9,946.0 with a corresponding storage of 4,000 acre-feet. Storage was static and inflow was passed for the remainder of the fiscal year. The maximum regulated release for the fiscal year was 558 c.f.s. and occurred on May 23, 1970. There was no flood control regulation during the fiscal year. Estimated total accumulated flood damages prevented by project through fiscal year 1969 were $629,000. Fiscal year costs were $1,803, and total costs to June 30, 1970, were $42,492. 15.

ARKANSAS RIVER BASIN, ARK. AND OKLA. Multiple-purpose plan authorizing features that serve navigation, flood control, and hydroelectric power purposes and afford storage for water supply, water quality control, sediment control, recreation, and fish and wildlife propagation in the Arkansas River Basin within Tulsa District are listed in table 19- C on Arkansas River Basin. For a comprehensive understanding of overall work authorized and accomplished under this heading, see Little Rock District's section of this report. Amounts authorized to be appropriated for combined comprehensive and multiple-purpose plan total $1,340,453,000. Project features on which construction has been initiated are reported separately in this section. 2. BANK STABILIZATION AND CHANNEL RECTIFICATION, ARK. AND OKLA. Location. Bank stabilization, cutoffs, and channel improvement work in reach of Arkansas River between Robert S. Kerr Dam site and Fort Smith, Ark., river miles 395.4 and 362, respectively. (See Geological Survey maps for Sans Bois (Okla.), Sallisaw (Okla.), and Fort Smith (Ark.-Okla.) quadrangles, scale 1:125, 000.) Existing project. Consists of training dikes, cutoffs, revetments, and other channel work, forms a unit in plan for navigation of Arkansas River. Final cost is $12, 700,000. (See table 19-B for authorizing legislation). Corrective bank stabilization in reach between Wilsons Rock and Fort Smith will also protect the critical location on the right bank near Bradens Bend, Okla. Therefore bank protection work authorized for that area by Flood Control Act of 1948 will not be required. Local cooperation. See requirements for entire project. Operations and results during fiscal year. All project structures were operated and maintained in a serviceable condition. Condition at end of fiscal year. Bank stabilization and channel rectification works from Wilsons Rock upstream to Robert S. Kerr Dam site were initiated May 1955. Additional structures and construction of protective works for bridges and channel in area where degradation is expected from operation of navigation channel began in April 1968. The project was completed December 1969. 3. LOW HEAD LOCKS AND DAMS, OKLA. There will be three lock-and-dam units on Arkansas and Verdigris Rivers in addition to Robert S. Kerr and Webbers Falls. With some channel cutoffs and enlargement work they will provide a navigable channel 9 feet deep from Fort Smith, Ark., to vicinity of Catoosa, Okla., where a turning basin will be provided. (See table 19-B for authorizing legislation.) A more detailed description for low head locks and dams is in following paragraphs. Total estimated cost of low head locks and dams, including turning basin, channel cutoffs and enlargement is $105,200,000. 3A. LOCK AND DAM NO. 13, CHANNEL IMPROVEMENT, ARKANSAS RIVER Location.

Jefferson, Madison, and Gallatin Rivers conjoin at Three Forks, Mont., to form Missouri River, which flows southeasterly 2,315 miles across or along seven States to Mississippi River, 17 miles above St. Louis. For description see page 1149, Annual Report for 1932. Practically entire length of section from Kansas City to mouth is within State of Missouri. Previous projects. For details see page 1891 of Annual Report for 1915, and pages 1153 and 1175 of Annual Report for 1938. Existing project. 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 waterway, cutoffs to eliminate long bends, closing minor channels, removal of snags, and dredging as required. Section under improvement (mouth to upper end of Rulo Bend) is 514.8 miles long (adjusted mileage). Ordinary and extreme fluctuations of stage are 16 and 38 feet, respectively. Estimated cost for new work is $238,950,000 (July 1970), exclusive of amounts expended on previous projects. (See table 20-C for authorizing legislation and table 20-B for total cost of existing project to June 30, 1970.) Local cooperation. Project provides that cooperation from benefited localities may be required, in case a comprehensive plan is adopted by Congress, for an apportionment of expense, where any improvement confers special benefit; and receipt of contributions from private parties, to be expended with Government funds upon authorized works where such would be in interest of navigation, is authorized by 1915 River and Harbor Act. Secretary of the Army approved general principle of cooperative construction on Missouri River below Kansas City on basis that 25 percent of cost of any special installation shall be paid by the United States and 75 percent by local interests. Total contributed by local interests in cooperation with the United States from 1918 to June 30, 1964, was $675, 663, of which $8,647 was returned to contributors. Local interests must share in cost of recreation facilities in accordance with provisions of the Federal Water Project Recreation Act of 1965. Local Interests have contributed $61,900 for cost sharing on construction of recreation in addition to construction portions of the facilities. Terminal facilities. Facilities for transferring grain, petroleum products, and other commodities are maintained at various locations on this section of the river. Facilities are listed in table 20-D. Operations and results during fiscal year. Regular funds, new work: Construction by contract of 87 dikes and 56 dike extensions totaling 30,894 linear feet, 41 lengths of revetment totaling 13,653 linear feet, initiation of construction of 3 dikes and 6 dike extensions totaling 1, 867 linear feet and 12 lengths of revetment totaling 6, 884 linear feet at a total cost of $2,473,667. Engineering and design, supervision and administration and survey and layout of channel and bank stabilization works was accomplished at a cost of $186,303. Construction of recreation facilities on a cost sharing basis in accordance with Public Law 89-72 was continued at a cost of $8,839. Work consisted of construction of boat ramps and engineering for development of future facilities. Maintenance: Repair by contract of 80,559 linear feet of dike, 138,487 linear feet of revetment; initiation of repair of 16 dikes totaling 4,553 linear feet and 24 lengths of revetment totaling 14,903 linear feet at a cost of $5,610,141. In addition, following work was accomplished by hired labor: repair of 25,062 linear feet of dikes, 66,308 linear feet of revetment, initiation of repair of two pieces of revetment totaling 1,260 linear feet, at a cost of $1,543,833; removal of 1,156,933 cubic yards of material from 12 localities by U.S. dredge Black and 104,500 cubic yards of material at two localities by mechanical grader at a cost of $593,053; real estate management, $2,856; surveys and mapping, $533,574; stream gaging and special working data, $324,136; engineering and design, $280,482; surveys and layout of construction, $65,958; and supervision and administration, $933,806. Income from grants and miscellaneous receipts totaled $218. Proceeds of $1,442 from the sale of maps and charts and outleasing of reservoir land were deposited in the U.S. Treasury. Local governmental units will be paid 75 percent of the income of $590 from lease rentals. Condition at end of fiscal year.

Work by hired labor forces consisted of removal of 63,600 cubic yards of point removal for channel correction; 37,800 tons of stone was salvaged from obsolete structures and used to repair 12,600 linear feet of dikes and revetments and 64,872 cubic yards of obstructions in the channel were removed and placed out of the designed channel. Condition at end of fiscal year. Construction was initiated on this section of the project (Sioux City to Rulo) in fiscal year 1928; and the scheduled completion date is fiscal year 1973 for Bank Stabilization and fiscal year 1975 for the Recreation Feature. The work was approximately 95.6 percent complete at end of the fiscal year. Work remaining to complete this section of project (Sioux City to Rulo) consists of construction of additional bank stabilization structures, strengthening of existing structures to improve their effectiveness and to prevent their deterioration prior to final stabilization of banks, refinement construction consisting of minor dike and revetment extensions and underwater sills to redistribute flow velocities, in order to develop more stable navigation project dimensions, and construction of recreation facilities. A reliable channel suitable for navigation is available through this section. Controlling depth at ordinary stages of the river is 8 1/2 feet, with additional depths available during high stages. Commercial navigation was inaugurated on this section in May 1939, and common carrier transportation service was inaugurated in October 1946. Six river side recreational sites are completed and in operation, two of these are proposing to enlarge their areas to provide camping facilities. (See table 21-B for total cost of work under existing project to June 30, 1970.) 3. SMALL NAVIGATION PROJECT SIOUX CITY, IOWA Location. Left bank Missouri River at Sioux City, Iowa. Existing Project.

The lake will provide storage capacity of 28,400 acre-feet for flood control and recreation. Authorized by 1968 Flood Control Act (Senate Document 87, 90th Congress). Estimated cost is $41,900,000 (July 1970) of which $2,030,000 is future non-Federal reimbursement for recreation cost sharing. Other non-Federal costs, for acquisition of water for recreation pool, are estimated at $400,000. Local cooperation. Local interests will be required to: a. In accordance with the Federal Water Project Recreation Act: (1) administer land and water areas for recreation and fish and wildlife enhancement; (2) pay, contribute in kind, or repay with interest, one-half of the separable cost allocated to recreation and fish and wildlife enhancement; (3) bear all costs of operation, maintenance, and replacement of recreation and fish and wildlife lands and facilities including water replacement; (4) provide the water required for initial filling and replenishment of evaporation losses of the recreation pool by purchase or other means consistent with Federal and State laws, to assure effective operation of the project for recreation and fish and wildlife enhancement; b. hold and save the United States free from damages due to water-rights claims resulting from construction and operation of the project; c. prevent encroachment on the flow-carrying capacity of the channel below the reservoir to the extent necessary to provide for effective reservoir operation in the interest of flood control; d. adequately inform affected interests, at least annually, that the project will not provide complete flood protection; and e. provide guidance and leadership in preventing unwise and uneconomical future development of the flood plain areas by encouraging prudent management techniques to reduce future flood losses. Operations and results during fiscal year. Initiated contract surveys and design studies by hired labor. Condition at end offiscalyear. Advance Engineering and Design studies in progress. 6. BIG SIOUX RIVER AT SIOUX CITY, IOWA AND S. DAK. Location. Near mouth of Big Sioux River in the vicinity of Sioux City, Woodbury County, Iowa and North Sioux City, Union County, South Dakota. Existing project. The project consists of excavating a new channel from the Missouri River to the Interstate Highway No. 29 Bridge to eliminate the sharp bend immediately downstream from the bridge. The reach of the existing channel downstream from the Interstate Highway Bridge would be abandoned. Project was authorized by the Flood Control Act of 1968, (Senate Document 94, 90th Congress). Estimated cost of the improvement $3,854,000 (July 1970), of which $3,640, 000 is Federal cost and $214,000 is non-Federal cost. Local Cooperation. Section 3 of the Flood Control Act approved 22 June 1936 applies. At a regular meeting of the City Council of Sioux City on 21 November 1966, the Council passed a resolution expressing a willingness and an ability to furnish the required local cooperation. The Union County Commissioners, Union County, South Dakota, have endorsed the project and provided resolutions which indicate their cooperation and willingness to furnish the necessary local cooperation for the South Dakota portion of the improvement. Operation and results during fiscal year. None. Condition at end of fiscal year. Work has not started. 7. BILLINGS, MONT. Location. At Billings and vicinity on Yellowstone River, Mont., 346 river miles upstream from its confluence with the Missouri River. Existing project. Plan consists of a system of ditches, channels, and levees by means of which flood-waters approaching the city from the west, east, or south may be diverted away from the area subject to flooding. Proposed plan is divided into three separate units, namely, the western, eastern, and southern units. Project authorized by 1950 Flood Control Act (H. Doc. 216, 81st Cong., 1st sess.). Estimated Federal cost (July 1960) is $4,590,000; estimated local cost (July 1960) is $353,000 for relocations, lands, and damages. Reexamination of feasibility of authorized plan is necessary because of the rapid expansion of the city of Billings, which took place since preparation of the project document in 1946, has extended the city beyond the protection limits proposed by the authorized project. Accordingly, this project has been reclassifed to "deferred" category. Local Cooperation. Section 3 of the Flood Control Act approved 22 June 1936 applies. City Council of Billings, furnished a resolution dated January 7, 1964, agreeing to provide right-of-way acquisition with complete acquisition to be financed jointly by the city of Billings and several irrigation companies. In addition to the formal resolution from city, the combined irrigation companies pledged $20,000 toward right-of-way and County Commissioners took action toward the local bridge problem. 641 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Operation and Results During the Fiscal Year. Continued preparation of the feasibility report to determine if an acceptable flood control project can be economically constructed. Condition at End of Fiscal Year.

Huntington section extends 311 miles from mile 127 to 438 immediately upstream from Foster, Ky., and includes locks and dams 15 to 17, inclusive, Belleville, Racine, Gallipolis, Greenup, and Captain Anthony Meldahl locks and dams. Louisville section extends 543 miles from mile 438 to mouth of river, and includes Markland and McAlpine locks and dams (with Louisville and Portland Canal) and locks and dams 43 to 53, inclusive. IMPROVEMENTS Navigation Page 1. Construction of locks and dams on Ohio River .................... ................. 667 Navigation (cont.) Page Open channel work, Ohio River ........... 669 NAVIGATION 1. CONSTRUCTION OF LOCKS AND DAMS ON OHIO RIVER Location. Ohio River is formed by junction of Allegheny and Monongahela Rivers at Pittsburgh, Pa., and flows generally southwesterly for 981 miles to join Mississippi River near Cairo, Ill. For description of river see page 1227, 1932 Annual Report. Previous projects. For details see page 1907 of Annual Report for 1915. Existing project. Provides for improvement of entire river by construction of locks and dams to provide a channel depth of 9 feet and for widening Louisville and Portland Canal at Louisville, Ky. Project provides for a lock with usable dimensions of 110 by 600 feet at each of the dams and, in addition, an auxiliary lock 56 by 360 feet is available at Emsworth, Dashields, Montgomery, and McAlpine locks and dams with an auxiliary lock at Gallipolis being 110 by 360 feet. Dashields is a fixed dam, while Emsworth, Montgomery, and Gallipolis are fixed dams with movable crests. Remaining dams are movable type, with navigable pass varying in width from 600 to 1,248 feet. In addition to navigable pass, movable-type dams are also provided with one or more regulating weirs. At McAlpine locks and dam a canal (Louisville and Portland) extends along left bank for 2 miles, with locks at lower end. Modifications to existing project under purview of Section 6, March 3, 1909 Act, provide for fixed dams with movable crests with two locks (110 by 1,200 feet and 110 by 600 feet) at New Cumberland, Pike Island, Hannibal, Willow Island, Belleville, Racine, Greenup, Captain Anthony Meldahl, Markland, Canneltori, Newburgh, Uniontown, and Mound City, two locks 110 by 1200 feet at Smithland, a 110 by 1200 foot temporary lock in addition to the existing lock at lock and dam 52, reconstruction to provide a 110 by 1,200 foot lock in addition to existing locks and a fixed dam with two sections of movable crest at McAlpine locks and dam, widening Louisville and Portland Canal to 500 feet, and construction of a temporary 110 by 1200 foot lock at lock and dam 52. Operation and care of locks and dams were included in project July 1, 1935, under provisions of Permanent Appropriations Repeal Act of June 26, 1934. Estimated Federal cost of new work (existing project) (1970), exclusive of Gallipolis locks and dam reported under Kanawha River project is $1,290,367,302; estimated non-Federal cost is $9,089,000. Foregoing estimate does not include expenditures on previous projects. Various items previously included in this project are considered inactive or unnecessary and are excluded from foregoing cost estimate. See page 693, Annual Report, 1968 for items and estimated cost. Under authority of 1910 River and Harbor Act, Louisville and Portland Canal was widened to 200 feet; locks and dams 40 and 42 eliminated; locks and dams 1 and 2 replaced by Emsworth locks and dam; lock and dam 3 replaced by Dashields locks and dam; and locks and dams 4, 5, and 6 replaced by Montgomery locks and dam. Locks and dams 24, 25, and 26 were replaced by Gallipolis locks and dam authorized by August 30, * All cost and financial statements for projects are listed at the end of this chapter.

Costs were $2,622,074 for Pittsburgh District, $3,033,059 for Huntington District and $3,810,248 for Louisville District. Condition at end of fiscal year. Navigation system of 29 locks and dams is in operation and 9-foot navigation throughout length of river is generally available at all times. At certain unstable bars project depth is maintained by dredging, supplemented by contraction works. (See "Open channel work, Ohio River.") Table D shows cost and year of completion of locks and dams now in operation. Existing project does not provide adequate facilities for present-day navigation due to obsolescence of structures. Since repair and modernization of these facilities would be extremely costly, replacement and reconstruction is being accomplished as rapidly as funds are made available for the purpose. Construction of lock and dam replacement program was initiated in fiscal year 1955. New Cumberland, Pike Island, Belleville, Racine, Greenup, Captain Anthony Meldahl, Markland, and McAlpine replacement locks and dams are in operation, replacing 451-584 0-72-43 24 old low-lift locks and dams. Construction of Hannibal locks and dam to replace locks and dams 12, 13 and 14 was initiated in fiscal year 1966; Racine locks and dam initiated in fiscal year 1964 has replaced locks and dams 21, 22 and 23; Cannelton locks and dam to replace locks and dams 43, 44 and 45 was initiated in fiscal year 1962; Newburgh locks and dam to replace locks and dams 46 and 47 and Uniontown locks and dam to replace locks and dams 48 and 49 were initiated in fiscal year 1965. For total cost of existing project, see table B. 2. OPEN CHANNEL WORK, OHIO RIVER Location. Under jurisdiction of district engineer in whose district the work is located. Portion of river included in project extends 974.7 miles from head of river at Pittsburgh, Pa., to mouth of Cache River (Mound City, Ill.). Open channel improvement from mouth of Cache River to mouth of Ohio River is under jurisdiction of Mississippi River Commission. Existing project. Before completion of canalization project, no project depth had been fixed by Congress under project for open channel work, but in order to properly aid packet and barge navigation it was necessary to secure a low-water channel with a minimum depth of from 4 to 6 feet, and a width, depending upon difficulty of running channel, of from 400 to 600 feet; also to permit movement of large coal tows, which movement occurred at stages of water exceeding 10 feet, it was necessary to remove points of projecting bars which formed at various locations along river. Accomplishment of this purpose involved concentration of current by closing back channels at islands with low dams, contraction and straightening wide, open channels by low dikes, dredging bars and shoals, and removal of snags and wrecks. Incidental to direct improvement of Ohio River is construction and maintenance of ice piers as required for protection of river craft. Stage of extreme high water on 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). Estimated cost of new work (1960) is $16,160,000, exclusive of following items which are considered inactive: Ice piers authorized by 1927 River and Harbor Act; reforestation of sloughs on Kentucky Peninsula near Evansville, Ind., authorized by 1930 River and Harbor Act; dredging to widen channel at certain points; and placing revetment at various points. Estimated cost of these items (1954) is $6,565,000. Operation of snag boats on Ohio River below Pennsylvania State line was included in project July 1, 1935, under provisions of Permanent Appropriations Repeal Act of June 26, 1934. See table E for authorizing legislation. Local cooperation. River and Harbor Act of January 21, 1927, authorizing construction of ice piers for general open channel work, imposes condition that before work is begun on any pier, local interests convey 69 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 to the United States free of cost such riparian rights as may be deemed necessary in connection with the improvement at 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. River and Harbor Act of July 3, 1930, provides for reforestation of sloughs of Kentucky Peninsula and bank protection and that no expense shall be incurred by the United States for acquiring lands required for purpose of this improvement (H. Doc. 409, 69th Cong., 1st sess.). However, since no serious overbank erosion has occurred since bank revetment in 1933-34, reforestation is not considered justifiable at this time and no local cooperation is required. Operations and results during fiscal year. Operation and maintenance, general: Dredging, where required to provide an adequate and dependable channel of project depth at minimum pool conditions, was executed. Dike and revetments maintained and routine work of maintaining navigation aids, removing snags, making channel studies, hydrographic surveys and mapping was performed as required. Channel soundings, hydrographic surveys, stream gaging operations, channel inspections and aids to navigation, and miscellaneous inspections and reports cost $500,369. Dredging by hired labor: Huntington District 4,500 cubic yards at $22,692 and Louisville District, 3,389, 560 cubic yards at $844,586, and dredging by contract Huntington District 21,130 cubic yards at $31,550. Rehabilitation. Minor hired labor repair to the revetment at Kentucky Peninsula was completed in the fiscal year at a cost of $8,535. Condition at end of fiscal year. New work under this project is substantially complete, since it is not anticipated that work on inactive portion of project will be accomplished. In addition to dredging, local stabilization of channel has been effected at various points by construction of dikes and revetment. Work which remains consists of dredging to widen channels at certain points to project depth. 670 OHIO RIVER TABLE A COST AND FINANCIAL STATEMENT See Section Total to in Text Project Funding FY 67 FY 68 FY 69 FY 70 June 30, 1970 Construction of New Work Locks and Dams Approp. $53,228,931 $64,069,284 $ 44,147,500 $51,714,502 $ 798,101,533, 3,s5,10 on Ohio River Cost 50,394,425 60,204,365 54,413,913 44,420,309 785,060,5621,3,6 Maint.

CUMBERLAND RIVER, TENN. AND KY. Location. Formed by junction of Poor and Clover Forks in Harlan County, Ky., about 694.2 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 Ohio River near Smithland, Ky. (See Geological Survey base maps of Tennessee and Kentucky.) Previous projects. For details see pages 1898 and 1901 of Annual Report for 1915, and page 1208 of Annual Report for 1938. Existing project. Below Nashville: Prior to adoption of 9-foot navigable channel defined in succeeding paragraphs, project for this section of river provided for construction of locks and dams A, B, C, D, E, and F, and dredging in the 43.6 miles from lock F to mouth to secure 6-foot navigation at extreme low water from mouth to lock and dam 1, Nashville, Tenn., (188.4 miles above mouth), first lock constructed under project for section of river above Nashville. Surmounting of dams A to F with movable crests was also provided. Dredging in lower river was made unnecessary by construction of lock and dam 52, Ohio River, which created a pool of more than 6-foot depth from lock F to mouth. Cost of new work for completion of 6-foot navigation project was $4,706,883, excluding amounts expended on previous projects. For pertinent data concerning locks and dams A to F, see page 1070 of Annual Report for 1962. Improvement of Cumberland River between mouth and Nashville was authorized for 9-foot navigation; increased project depth to be obtained by construction of three moderate height dams with lockage facilities, designated at Kuttawa (Eureka), Dover, and Cheatham, to replace existing locks A to F, inclusive, below Nashville, and lock 1, above Nashville. (See paragraph 22-B for authorizing legislation.) Subsequent authorities provided for construction of hydroelectric power-generating facilities at Cheatham Dam, river mile 148.7, * All cost and financial statements for projects are listed at the end of this chapter. All other tables are referenced in text and also appear at the end of this chapter. 677 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 and modification of project for navigation on Cumberland River, Tenn. and Ky., to provide, in lieu of previously authorized works at Kuttawa, mile 32.2, and Dover, mile 100.1, for construction of a multiplepurpose improvement for navigation, flood control, and hydroelectric power consisting of a dam, lock, and powerplant near mile 30.6 on lower Cumberland River and a canal for navigation and other purposes connecting proposed reservoir with reservoir formed by Kentucky Dam on the Tennessee River. The project is known as Barkley Dam and Lake Barkley. Provision of interconnecting canal, involving excavation of a channel through narrow watershed divide about 2.5 miles upstream from damsite, will make alternative routes available for navigation between either Cumberland or Tennessee Rivers and Ohio River, and will afford integrated operation of Barkley and Kentucky Reservoirs through diversion of flows in interests of flood control and power production. Estimated cost of modified project for 9-foot navigation and multiplepurpose development is $174,873,900 (July 1970). (See table 22-C for listing of principal features.) Under flood conditions as regulated by upstream reservoirs, extreme fluctuation in stage of river below Nashville, Tenn., varies at different localities from about 16 to 55 feet above minimum pool levels. Ordinary fluctuations vary with power flows from as much as the allowable 3-foot drawdown below normal pool elevation 385 at Cheatham Lock and Dam to a range of about 7 feet at Nashville. Seasonal variation in normal headwater levels at Lake Barkley is 5 feet, which in combination with power flows produces fluctuations up to 10 feet below Cheatham Lock and Dam. Above Nashville: Authorization (See Table 22-B) provided for 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 mouth) to Waitsboro Shoals (324.6 miles), and 4-foot navigation from Waitsboro Shoals to Burnside (3 miles); provision also being made for periodic removal of snags and similar obstructions from Nashville (lock and dam 1) to Burnside (327.6 miles). Project was modified by raising dam No. 1 by 3 feet. Locks and dams 1 to 8, inclusive, and 21 were completed and placed in operation during 1888 through 1924. Raising dam 1 by installation of crest wickets was completed in October 1931. Proposed locks and dams 16 and 17 were eliminated from project upon authorization of Lake Cumberland (Wolf Creek Reservoir), construction of which has also resulted in permanent inundation of lock and dam 21. Further consideration of previously projected locks and dams 9 through 15, inclusive, is precluded under existing project as modified which resulted in replacing locks and dams 1-8. For statistical data concerning lock and dam 8, placed in an inoperative status in 1951, see page 1694 of Annual Report for 1950; together with details on locks and dams 1 to 7 and 21, displaced, and other structures originally contemplated under project (pp. 1694 and 1695). Construction of Old Hickory, Carthage, and Celina Dams above Nashville was also authorized for navigation and power. The dam and reservoir authorized for construction on Cumberland River near Carthage, Tenn., has been redesignated as Cordell Hull Dam and Reservoir. Cost of Old Hickory and Cordell Hull projects, including locks, is estimated as $124,835,100 (July 1970). Estimated cost of Celina Dam (1959) is $39,100,000. (See table 22-C at end of chapter for listing of principal features.) Under flood conditions as presently regulated, including effect of surcharge operation of Old Hickory project, extreme fluctuations of stage in this section of river vary from a range of 35 feet at Nashville (mile 191) to a maximum of 46 feet immediately below Old Hickory Dam (mile 216.2), and from an 8-foot variation in headwater at dam to 36 feet in vicinity of Carthage, Tenn. (mile 313.5), present head of navigation; with variations up to 35 feet at Celina, Tenn. (mile 380.8) and 29 feet in tailwater at Wolf Creek Dam (mile 460.9). Maximum fluctuations under ordinary conditions from power flows vary from about 7 feet at Nashville to 14 and 3 feet, respectively, in tailwater and headwater of Old Hickory Dam, and at other key points as follows: 13 feet at Carthage; 18 feet at Celina; and 19 feet at Wolf Creek Dam. Further details on project authorization for river sections below and above Nashville are shown on Table 22-B. Local cooperation. Fully complied with for 6-foot navigation project. Under modified project for 9-foot navigation and multiple-purpose development, recreation features of reservoir components are subject to certain conditions of non-Federal cost-sharing under Federal Water Project Recreation Act of 1965. Terminal facilities. At Nashville, Tenn., there is a 5- story terminal building 300 feet long and 140 feet wide, built of reinforced concrete with large and convenient loading platforms, electric elevator and gantry crane, with railroad connections, municipally owned and open for public use. There is an additional terminal, privately owned, with modern facilities and railroad connections, also available for public use. Major oil companies have constructed terminals for transfer of petroleum products. There are also privately owned terminals at Nashville for transfer of sand and gravel, cement, scrap metals, sulphuric acid and molasses; at Old Hickory, Tenn., for transfer of chemicals; at Burnside, Ky., for transfer of coal; at Clarksville, Tenn., for transfer of sand and gravel; and near Smithland, Ky., for transfer of limestone. Governmentowned facilities for transfer of coal are at Cumberland City Steam Plant. In addition there are many unimproved private landings along river. Facilities considered adequate for existing commerce. Operations and results during fiscal year. New work: Below Nashville: Paving of roads and parking areas in Cheatham lock operations building and service area was accomplished under contract. Construction of left 678 NASHVILLE, TENN., DISTRICT bank sewerage improvements, Cheatham project, was contracted near end of the year and work initiated. Reconstruction of a launching ramp below Cheatham Dam was performed by hired labor. Work continued under contract for an additional switchyard bay at the Barkley powerplant. Construction of public-use facilities, comfort stations, and washhouses for two sites, Barkley project, was contracted prior to end of the year. Miscellaneous small items construction and installation operations relating to dam and powerplant and buildings and grounds were performed by hired labor, as were preparation and issuance of plans and specifications for work contracted during the year. Costs for new work were $484,562. Above Nashville: Construction of sewage treatment plant and public use facilities at Shutes Branch site, Old Hickory project, under two contracts was completed. Incident to construction of Cordell Hull project, construction of the powerplant was contracted and work undertaken. Under cost reimbursable contract previously entered into with the State of Tennessee for relocation and adjustment of roadway facilities in the reservoir area, operations were continued. Operations were completed under relocation contracts covering telephone lines of the North Central Telephone Cooperative Corp., and continued under contracts for power and telephone lines of the Upper Cumberland Electric Membership Corp., and the Twin Lakes Telephone Cooperative Corp., respectively. Work was completed under contracts for roadway and bridge relocations in Smith County portion of reservoir, and in Jackson County (first portion). Work was continued under supply contracts for 3-58,200 hp turbines, 3-37,037 kva generators, 3-42,700 kva transformers, 13.8 kv metal-clad switchgear, generator neutral grounding equipment, metal-enclosed bus structures, and lock feeder unit substation for the powerplant.

Reservoir boundary line marking, preparation of plans and specifications, and miscellaneous small items construction and installations operations relating to dam and powerplant were accomplished by hired labor. Project lands acquired totaled 4,082 acres. Costs for new work were $7,100,154. Operation and maintenance: Barkley, Cheatham, and Old Hickory locks and dams were operated as required. Maintenance and improvement operations included unwatering lock valves and modification of slowdown gate operating controls, cleaning and rustproofing spillway gates and gate chains at the Barkley project; completion of powerplant remote control facilities, installation of piling and riprap for spillway gate bulkhead storage area, replacement of anchor bars on lower lock gate, and replacement of hydraulic lines across upper gate sill at Cheatham; unwatering and repair of lock gates, stabilization of miter sills, and overhaul of floating mooring bitts at Old Hickory; and regalvanizing handrails at Cheatham and Old Hickory locks. Temporary maintenance was continued as necessary at Cordell Hull lock pending placement in permanent operation. Operation of powerplants was continuous except for normal interruptions and necessary shutdowns for inspection and maintenance purposes. Total net energy generated at Barkley Dam (688,822,728 kw-hr) was made available through Department of the Interior to the Tennessee Valley Authority, Southern Illinois Power Cooperative, Big Rivers Rural Electric Cooperative Corporation, and Indiana Statewide Rural Electric Cooperative, Inc., Hoosier Energy Division. Total net energy generated at Cheatham Dam (170,588,500 kw-hr) and Old Hickory Dam (459,364,036 kw-hr) was made available to the Tennessee Valley Authority for distribution. Power revenues were $2,041,000, $772,000, and $1,370, 000, respectively. Benefits attributable to Barkley effect in reduction of flood flows on Cumberland and lower Ohio and Mississippi River during year are estimated as $602,000. Activities under reservoir management program comprising malaria control, shoreline sanitation, land management and disposal, and maintenance of public-use facilities continued. Channel snagging and dredging was done by hired labor. Condition at end of fiscal year. Below Nashville: Locks and dams A to F, inclusive, completed under 6-foot navigation project for this section of river, had been replaced by Barkley and Cheatham locks and dams. Under authorized modification of existing project for multiple-purpose development, including further improvement below Nashville for 9-foot navigation, new work as a whole is about 99 percent complete. Construction of Cheatham lock and dam was completed in November 1960. See page 1078 of 1962 Annual Report for chronology of construction. Under authority for provision of additional recreational facilities at completed projects to meet increased public-use demands, 11 boat launching ramps have been graded and paved and the following installed: 100 picnic and camping units and 4 shelters; 56 grills; and 12 comfort stations. Construction of left bank sewerage improvements initiated near the close of the fiscal year, and proposed additional recreational facility construction remain for accomplishment under Cheatham project. Work under contract for provision of an additional switchyard bay at Barkley powerplant was complete. Work was not commenced on construction of public-use facilities, comfort stations, and washhouses for two sites contracted near the end of the year. With exception of a permanent transfer of about 5,946 acres in fee and a use permit (flowage rights) over 537 acres from Tennessee Valley Authority, all land requirements of the project have been acquired. After excluding disposals of 13,383 acres in fee and 99 acres 679 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 in easements, a net total of 101,459 acres remain in the project (69,735 acres, fee; 24,357 acres, easement; and 7,367 acres under use permit). Barkley project as a whole is about 99 percent complete and in full operation. Lock was opened to navigation on July 8, 1964. The four power units were placed in commercial operation January 21, February 4, March 7, and March 30, 1966. Total new work costs for this section to June 30, 1970, were $178,475,678 including $685,000 public works funds. Above Nashville: Prior to modification of existing project for this section of river in 1946, locks and dams 1 to 8, inclusive, and 21 had been completed; initiation of work on lock and dam 1 in September 1888 marking commencement of construction under project. For dates on which completed structures were placed in operation, see table under "Existing project," Annual Report for 1950. Lock and Dam 21, completed in October 1911, has since been inundated by Lake Cumberland which also eliminated projected locks and dams 16 and 17. Lock and dam 1 was demolished in connection with construction of Cheatham project below Nashville. Lock and dam 2 was demolished with construction of Old Hickory project, which inundated locks and dams 3 through 7. Old Hickory project provides a through channel for 9-foot navigation on the Cumberland above Nashville to vicinity of Carthage, Tenn., at river mile 313.5, present head of navigation. Lock and dam 8, placed in an inoperative status November 30, 1951, has been displaced with partial impoundment of Cordell Hull Reservoir which, upon project completion, will extend the 9-foot waterway to the Celina damsite, river mile 385.4, at the Kentucky-Tennessee State Line. New work under authorized modification of existing project for this section of river, as a whole, is 60 percent complete. Old Hickory project was completed for full beneficial use December 1957 with placement of last power unit in commercial operation. Further details are given on page 1080 of Annual Report for 1962. Grading and paving 43 boat launching ramps and installation of 208 picnic and camping units, 161 outdoor grills, 10 pittype and 4 flush-type toilets, and 4 picnic shelters were accomplished under program for provision of additional recreational facilities at completed projects to meet increased public use demands. Proposed additional recreational facility construction remains for accomplishment under project. Construction of Cordell Hull project started May 1963 under contracts for first-stage cofferdam and access roads to the damsite which are complete. Operations under continuing contract for lock and dam features, initiated in July 1964, were completed in October 1966. Additional contracts have been completed for phase 1 reservoir clearing; channel dredging below lock; construction of warehouse and storage area; construction of secondstage powerhouse cofferdam; relocation of facilities of Tri-County Electric Membership Corp., South Central Bell Telephone Co., East Tennessee Natural Gas Co., and North Central Telephone Cooperative; Smith County road and bridge relocations; and Jackson County (first portion) road and bridge relocations.

AUTHORIZED ALTERATION OF BRIDGES See table 22-G FLOOD CONTROL 5. CUMBERLAND, KY. Location. At Cumberland, Ky., on Poor Fork of Cumberland River about 23 miles above its confluence with Clover Fork near Harlan, Ky. Existing project. Provides for local flood protection at Cumberland, Ky., by enlargement of existing channel to a bottom width of 70-80 feet, beginning about 500 feet above Whitesburg Road bridge, at mouth of Looney Creek, and extending downstream through town 6,830 feet to about 3,266 feet below junction of Cloverlick Creek. Lower reaches of channels of the two tributary creeks would be widened to a minimum of 36 feet for 1,300 and 1,015 feet, respectively. Incidental work includes riprapping of channel cut slopes and banks, new bridge construction and pier modifications, strengthening certain existing retaining walls and building foundations, and relocations involving telephone and power lines, sewers, and water mains. Works are designed to provide a reasonable degree of protection, resulting in prevention of about 95 percent of experienced average annual flood losses. Project was authorized by 1950 Flood Control Act. Estimated cost of new work (July 1969) is $511,800 for construction, Federal; and $240,000 for lands and damages, non- Federal. Local cooperation. Project was originally planned for partial protection by channel clearing and cleaning, and carried in an inactive status following performance of major portion of work by local interests without expense to the Government. Recent study indicated economic feasibility of more extensive improvement as now contemplated, which can properly be done within discretionary authority of Chief of Engineers under existing project authorization. In accordance with this authorization, provisions of 1936 Flood Control Act as amended, apply; and local interests also shall prescribe and enforce regulations to prevent encroachment upon stream channel after construction of project. Assurances were furnished in form of a resolution of city council accompanying a letter of Mayor of Cumberland, Ky., dated September 7, 1962. Bond issue for financing city's share of project costs approved in regular general election November 5, 1963. City was furnished lands requirements and has developed preliminary ownership data. Local interests have reached an agreement with the State for required bridge construction under cost sharing arrangement. Further action has been deferred pending resolution of 682 NASHVILLE, TENN., DISTRICT financial difficulty on part of city stemming from inability to sell the bond issue at prescribed interest rate. Operations and results during fiscal year. Administrative cost only incurred. Condition at end of fiscal year. Contract plans and specifications completed; construction awaits fulfillment of right-of-way requirements. 6. EVARTS, KY. Location. Evarts, Harlan County, Ky., situated at the confluence of Yocum Creek with Clover Fork, Cumberland River, approximately 7 miles east of city of Harlan. Project. Provides for partial flood protection at Evarts through snagging and clearing and channel widening and deepening to uniform grade within 2-mile reach of Clover Fork, and snagging and clearing of tributary stream Yocum Creek, for a distance of 1.8 miles above its mouth. Construction was authorized by Chief of Engineers under authority of Section 208, 1954 Flood Control Act, Excavation of existing channel of Clover Fork to a minimum width of 50 feet would begin approximately 1,000 feet below the bridge at community of Kilday and extend some 10,950 feet upstream to a point 800 feet above the confluence of Bailey Creek. Incidental work involves removal of two abandoned bridge piers near lower limit of project. Estimated cost of new work (July 1970) is $37,600 for construction, Federal; and $1,200 for lands and damages, non-Federal. Local cooperation. Provisions of Flood Control Act of June 22, 1936, as amended, pertaining to ordinary conditions of cooperation with respect to lands and damages, and maintenance of works of improvement apply, and local interests also shall prescribe and enforce regulations to prevent encroachment upon improved stream channel. Operations and results during fiscal year. Project of modified scope as described above was approved July 16, 1968 for construction under authority of 1954 Act in lieu of improvement of larger scope as originally contemplated under Section 205, Flood Control Act of 1948, as amended; see 1968 Annual Report. At the request of local interests, the plan of improvements was further revised during the year to delete the proposed work in Yocum Creek. Administrative costs only were incurred during the year. Condition at end of fiscal year. No work has been undertaken pending assurances of local cooperation in modified project. 7. MARTINS FORK LAKE, KY. Location. Dam planned at mile 14.8 on Martins Fork of Clover Fork, Cumberland River, about 8 miles southeast of city of Harlan, with reservoir extending about 5 miles upstream within Harlan County, southeastern Kentucky. Existing project. Project approved in general accordance with recommendations of House Document 413, 86th Congress, by 1960 Flood Control Act, as amended by Public Law 88-253, was designed for purposes of flood control, power, and recreation as an integral unit of a coordinated plan for development of water resources of Cumberland River Basin. With the view of a net gain in power potential on a system basis, the plan of improvement incorporated appropriate flood control storage in the proposed project and corresponding adjustment in operations of Lake Cumberland (Wolf Creek Dam) for flood control and power, which in effect constituted a transfer of reservoir capacity without entailing a change in flood control benefits. Further detailed study giving full consideration to power capabilities and marketing arrangements indicated the advantage of maintaining present storage allocation at Wolf Creek and use of all available storage capacity of Laurel River Reservoir for power. As modified within discretionary authority of the Chief of Engineers, the project is now under construction in primary interests of power production and recreation, at an estimated cost of $34,600,000 (July 1970). Dam will be rockfill type, about 1,420 feet long and about 282 feet above streambed. An uncontrolled spillway will be in a saddle on left bank about 400 feet from dam, consisting of an uncontrolled rock cut 750 feet long, discharging into an unlined lateral channel which will direct flows back into main stream some distance below project site. A powerhouse of conventional indoor-type, with an installation of 61, 000 kilowatts in a single unit, is to be directly at downstream toe of dam. At top of power pool, spillway crest at elevation 1018.5 above mean sea level, reservoir will cover 6,060 acres. It will provide a total storage capacity of 435,600 acre-feet below elevation 1018.5, including active storage of 185,000 acre-feet within a drawdown range of 36.5 feet allocated for power production, and leaving a pool of at least 250,600 acrefeet at elevation 982, covering an area of 4,200 acres, available at all times for public use and conservation purposes. Local cooperation. None required. Operations and results during fiscal year. Work was initiated under contracts for Stage II Dam construction and supply of 1-98,000 hp hydraulic turbine. Hired labor operations included reservoir boundary line marking, preparation and issuance of plans and specifications for work contracted, and engineering and design on other project features.

A combination earth and concrete gravity-type dam, hydroelectric powerplant, and reservoir for primary purposes of flood control and power production, with a permanent pool for publicuse and conservation purposes. See page 1094 of 1962 Annual Report for project details. Estimated cost of project is $80,394,100 (July 1970). Local cooperation. None required on completed project; future recreation development subject to certain conditions of non-Federal cost-sharing under Federal Water Project Recreation Act of 1965. Operations and results during fiscal year. New Work: Additional construction of recreational facilities by hired labor. Operation and maintenance: Dam was operated and structures and appurtenances maintained as required, including completion of foundation drilling and grouting for relief of drainage problem under embankment section. Operation of powerplant was continuous except for normal interruptions and necessary shutdowns for inspection and maintenance purposes. Total net energy generated (697,526,600 kwhr) was made available through Department of the Interior to Tennessee Valley Authority for distribution. Benefits attributable to reservoir effect reduction of floodflows on Cumberland, lower Ohio and Mississippi Rivers estimated as $1,820,000. Activities under reservoir management program involved shoreline sanitation, malaria control, land management, and maintenance of public-use facilities. Condition at end of fiscal year. Project commenced August 1941 and was completed for full beneficial use August 1952. For chronology of construction and major items of work performed see page 1095 of 1962 Annual Report. Flood damage reductions to date amount to $31,272,000. Power revenues total $35,640,372. 17. LAUREL RIVER LAKE, KY. Location. Damsite is at mile 2.3 on Laurel River, a tributary of Cumberland River, in south-central Kentucky. The two streams meet about 9 miles below Cumberland Falls, a prominent physiographic feature at head of Lake Cumberland which is formed by Wolf Creek Dam. Reservoir will extend 19.2 miles upstream to site of Corbin, Ky., water-supply dam and lie within Laurel and Whitley Counties. 18. OTHER AUTHORIZED MULTIPLEPURPOSE PROJECTS INCLUDING POWER (See table 22-K.) 19. SURVEYS Fiscal year costs were $124,156, of which $118,007 were for flood control studies and $6,149 for coordination with Soil Conservation Service on review of watershed studies. 20. COLLECTION AND STUDY OF BASIC DATA Fiscal year costs were $44,808 for flood plain information studies, $6,728 for technical services to others, and $30,952 for flood plain management services, totalling $82,488. Flood plain studies completed and in progress are in table 22-L. 686 NASHVILLE, TENN., DISTRICT 21. RESEARCH AND DEVELOPMENT Fiscal year costs were $4,036 for miscellaneous hydrologic studies involving collection and processing of streamflow and rainfall data. Existing project. Multiple-purpose improvement combining flood control with water quality control and recreation development adopted by 1965 Flood Control Act (H. Doc. 244, 89th Cong.), in general accordance with recommendations. Dam will be earthfill type, about 730 feet long and rising 103 feet above streambed, with uncontrolled side-channel spillway 400 feet wide cut into rock. Outlet works provide for release of water from reservoir at varying levels. Drainage area above damsite is 56.1 square miles. At full pool level, spillway crest at elevation 1338 above mean sea level, reservoir will cover 675 acres and contain 21,800 acre-feet of storage capacity. Provision is made for 18,100 acre-feet of reservoir capacity between elevations 1338 and 1300 for control of floods in winter and spring season, and 14,800 acre-feet (El. 1338-1310) during summer and fall, in conjunction with which storage of 3,300 acre-feet would be available on a seasonal basis to meet streamflow requirements for water quality control and fish life below the dam. A minimum permanent pool of 3,700 acre-feet, 270 acres in extent, will thus be provided during potential flood seasons; and during late spring and summer when flood storage can be reduced, the lake is to be operated generally at a higher level (El. 1310) to maintain a larger surface area of 380 acres for recreation and to provide the required seasonal storage for releases of water during critical low-flow periods. Project will prevent major portion of average annual flood losses at Harlan and result in significant stage reductions with related benefits along rural reaches and at other urban areas downstream. Estimated cost of project, including planned initial recreation development, is $6,600,000 (July 1970), of which $325, 000 is subject to reimbursement by local interests. Local cooperation. Federal Water Project Recreation Act of 1965 applies with regard to non-Federal participation in recreation development, in addition to which local interests are to provide certain safeguards to ensure functioning of reservoir as intended. Presently estimated cost to non-Federal interests for participation in provisions for recreation as now envisioned for reasonably complete development of that purpose is $498,000 for construction, and $35,000 annually for operation, maintenance, and major replacements related to the recreation function. Annual costs of $23, 000 and reimbursement of $325,000 in project first costs allocated to recreation and fish and wildlife enhancement are estimated as representing non-Federal responsibility based on planned level of initial development for these purposes. Flexibility in size and responsibility of recreation development is accorded under Recreation Act, depending upon intentions of non-Federal interests to cooperate; project authorization also provides that required local participation in the recreational feature may be modified to conform with standards established pursuant to studies by Appalachian Regional Commission. Operations and results during fiscalyear. Engineering and design continued. Condition at end of fiscal year. Preconstruction planning 65 percent complete. 687 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 TABLE 22-A See Section in Text Project Funding 1. Cumberland River, New Work Tenn. and Ky.' Approp.

CONSTRUCTION OF LOCKS AND DAMS, OHIO RIVER For report on this improvement see this heading under Ohio River. 2. GREEN AND BARREN RIVERS, KY. Location. Green River rises in Casey County, Ky., flows northwesterly 370 miles, and empties into Ohio River about 8 miles above Evansville, Ind. Barren River rises in Monroe County, Ky., flows northwesterly 130 miles, and empties into Green River one-half mile above lock 4 and 149.5 miles above mouth of Green River. Existing project. Six locks and dams on Green River and one on Barren River to give, with channel work in pools of dams, a navigable depth of 9 feet and width of 200 feet from Ohio River to mile 103 Green River, 3.2 miles upstream from Paradise, Ky.; a navigable depth of 5.5 feet from mile 103 Green River to Fluctuations in stage vary considerably at different locks. At lock 3, Green River, ordinary high stages are from 12 to 15 feet above pool level, and at lock 1, Barren River, from 7 to 10 feet above pool. Maximum stages of record are 34 feet above normal pool stage at lock 3, Green River, and 29 feet at lock 1, Barren River, obtained during floods of 1937 and 1913, respectively. (See table 23-B for authorizing legislation.) Local cooperation. Fully complied with. Terminal facilities. Considered adequate for existing commerce. (See table 23-D on terminal facilities.) Operations and results during fiscal year. Consisted of operation and maintenance of locks and dams, 1 to 3, Green River, maintenance of lock 4, Green River and lock and dam 1, Barren River, and removal of shoals, snags, and slides as required to maintain adequate channel for existing traffic between mouth of Green River and dam 4 at mile 149, Green River. Condition at end offiscalyear. Lock 1 and Lock and dam 2, Green River, and lock and dam 1, Barren River, were in good condition. Reconstruction of Dam 1, Green River, was started in January 1970 and advanced to 7 percent complete for the fiscal year at a cost of $57,146. poor condition. Dam 4, Green River, failed May 24, 1965, when 120 feet washed out. Breach has later widened, and repairs are deferred pending completion of survey report for navigation on Green River. Pool of dam 1, Barren River, is maintained for local small boat use, but navigation through lock is suspended because of loss of lower pool. Operation of locks 5 and 6, Green River, was discontinued August 1951, as they were no longer used by river traffic. Controlling project depth in lower 103 miles of Green River is 9 feet; controlling depth from mile 103 to Bowling Green, Ky. is 5.5 feet. Under permit issued by District Engineer on August 20, 1963, private interests dredged channel of Green River to extend 9-foot depth to coal loading terminal at mile 105.7.

Rises in northern Pennsylvania, flows northwestward into New York, thence generally southwestward to Pittsburgh, Pa., where it joins with Monongahela River to form the Ohio. It is 325 miles long. (See Geological Survey Charts for western Pennsylvania and southwestern New York.) Existing project. Provides for eight locks and dams to afford slack-water navigation from Pittsburgh, Pa., 72 miles to above East Brady, Pa. Controlling depth through canalized portion is 9 feet at normal pool level, and channel width varies from minimum of 200 feet to full width of river at mouth. Cost of new work for completed project is $18,157,860. (See tables 25-B and 25-C for authorizing legislation and locks of dams on Allegheny River, Pa.) * All cost and financial statements for projects are listed at the end of this chapter. All other tables are referenced in text and also appear at the end of this chapter. 765 451-584 0-72-49 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Local cooperation. Fully complied with. Terminal facilities. City of Pittsburgh constructed a modern wharf for river freight. There are numerous privately maintained terminals and docks, consisting of tipples, various types of hoists, chutes, and pipelines for use in loading and unloading coal, stone, sand, gravel, petroleum products, steel products, and other commodities. Transshipment of freight between river and railroads is handled at privatley owned river-to-rail terminals. Existing private terminals are adequate for shipments and receipt in Pittsburgh District of type of commerce now in existence. Operations and results during fiscal year. Operation and maintenance, general: Locks were operated as required and necessary repairs made to structures to maintain them in serviceable condition at cost of $570, 748, maintenance repairs at locks and dams were accomplished at cost of $98,924. Condition at end of fiscal year. Existing project is complete, last lock was placed in service in 1938. All locks and dams are in good condition. Navigation channel has been widened at certain points and, in general, maintained to project depth, thus affording adequate depth for passage of commercial tows. 2. CONSTRUCTION OF LOCKS AND DAMS, OHIO RIVER See this heading under Ohio River portion. 3. LAKE ERIE-OHIO RIVER CANAL, OHIO AND PA. Location. In the Beaver-Mahoning and Grand River basins in western Pennsylvania and northeastern Ohio, between Lake Erie on the north and the Ohio River on the south. Existing project. Provides for a canal extending from the confluence of the Beaver and Ohio Rivers up the Beaver and the Mahoning Rivers by a series of seven locks and dams to a point near the north city limits of Warren, Ohio; thence by a land cut through the divide between the Ohio River and Lake Erie drainagebasins; thence through a summit reservoir formed by a dam across the Grand River near Harpersfield, Ohio; thence to Lake Erie. The total length of the canal would be about 120 miles. The combined lift of the south slope locks would be 159 feet and that of the north slope locks, 271 feet. Dual locks with usable dimensions of 84 feet by 720 feet would be provided. A proposed channel with a minimum depth of 12 feet and 15 feet over lock sills and in restricted reaches will be provided. Minimum bottom width of channel will be 300 feet except in reaches of Youngstown and Warren, Ohio, where developments along the river limit the width to 200 feet and 250 feet, respectively. Operation and maintenance of the locks and dams will be a Federal responsibility. Project was authorized by 1935 River and Harbor Act. The Appropriation Committees directed in their reports in connection with the 1968 Appropriation Bill that further planning should exclude navigation purposes and that planning work should include a reanalysis of reservoir's design and operation to make maximum provision for water supply storage, municipal and industrial water, water quality control, and other water resource purposes in absence of any requirements for navigation purposes. Estimated initial Federal cost for new work (1966) $968,000,000 (includes $9,545,000 reimbursable by non-Federal interests; estimated non-Federal cost is $67,700,000 (excludes required reimbursement.) Local cooperation. Local interests are required to provide without cost to the United States all lands, easements, and rights-of-way required for construction and subsequent maintenance of the navigation features of the project, except in the Grand River Reservoir and the divide cut, and for aids to navigation upon request of the Chief of Engineers, including suitable areas determined by the Chief of Engineers to be required in the general public interest for initial and subsequent disposal of spoil, and also necessary retaining dikes, bulkheads, and embankments therefor or the costs of such retaining works; hold and save the United States free from damages due to the construction, operation, and maintenance of the navigation features; bear a proportionate share of the cost of bridge alterations over the existing channels of the Beaver, Mahoning and Grand Rivers in accordance with principles of the Truman-Hobbs Act, as amended; assume all obligations of owning, including maintaining, operating, and replacing all railway and highway bridges altered or constructed as part of the multi-purpose project, including any additional cost of maintenance or operation which may be required because of the project; provide and maintain terminal and transfer facilities along the waterway and at the Lake Erie terminus adequate to handle the commerce which will use the waterway, with depths in the berthing areas and local access channels serving the navigation channel commensurate with the depths provided in related project areas, with terminal facilities at Lake Erie open to all on equal terms; accomplish all utility relocations and alterations from the mouth of the Beaver River to the beginning of the divide cut north of Warren, Ohio and from the northern dam of the Grand River Reservoir to the terminus at Lake Erie; not withdraw water for consumptive use, nor divert water around the locks, from the water supply provided by the project works; in accordance with the Federal Water Project Recreation Act administer project land and water areas for recreation and fish and wildlife enhancement; pay, contribute in kind, or repay (which may be through user fees) with interest one-half of the separable costs allocated to recreation and fish and wildlife enhancement, and bear all costs of operation, maintenance, and replacement of recreation and fish and wildlife lands and facilities the estimated cost of which is $9,545,000. Local political subdivisions in the States of Ohio and Pennsylvania have not been requested to submit assurances of local cooperation. However, State of Pennsylvania will not provide any of the local cooperation required for project. State of Ohio made no commitment pending further study of 766 PITTSBURGH, PA., DISTRICT project. Coordination has been effected with various agencies relative to development of data pertinent to revised project purposes. Terminal facilities. None in the lower Beaver River area. The Lake Erie terminus remains to be determined. Operations and results during fiscal year. New work: Pursuant to Congressional directive all work incident to navigation elements of the project was terminated and future planning confined to the Grand River Reservoir. The reanalysis study of Grand River Reservoir's design and operation to make maximum provision for municipal and industrial water supply storage, water quality control and other water resource purposes in absence of any requirements for navigation continued. Letter-type report for ultimate submission to Congress was submitted to Division Engineer, Ohio River Division. Condition at end of fiscal year. The reanalysis report is complete to extent necessary for determination of project feasibility, a public hearing, and review by State of Ohio. State of Ohio has indicated it will not be in a position to provide a statement regarding its participation in water supply and recreational features of project until results of its current studies of Northeast Ohio Water Development Plan are known. This study is scheduled for completion in spring of 1971. Final report will be submitted thereafter. 4. MONONGAHELA RIVER, PA. AND W. VA. Location. Formed by junction of Tygart and West Fork Rivers about 1 mile south of Fairmont, W. Va., and flows northerly for 128.7 miles to its junction with Allegheny River, forming Ohio River at Pittsburgh, Pa. (See Geological Survey Charts for southwestern Pennsylvania and northern West Virginia.) Previous project. For details see Annual Report for 1963, page 1070. Existing project. Provides for improvement of river by 9 locks and dams to afford slack-water navigation for its entire length from Pittsburgh to above Fairmont, W. Va. Original locks and dams 7, 8 and 9 were replaced by new locks and dam 7 and 8 in 1925. Increased traffic necessitated enlargement and improvement of locks and dams 1 to 6 between Pittsburgh and Rices Landing, Pa., by building two parallel chambers and fixed concrete dams during 1905 to 1932. Locks and dam 1 were eliminated in 1938 by raising Emsworth Dam, Ohio River. Reconstruction of lock 2 was completed in 1953 to provide two modern navigation chambers. Construction of Maxwell locks and dam and the reconstruction of dam 4 have allowed for removal of obsolete locks and dams 5 and 6. Small and antiquated original locks and dams 10 to 15, inclusive, have been replaced by three modern structures. Morgantown lock and dam, initial step in replacement program, was completed in 1950 replacing locks and dams 10 and 11. Hildebrand lock and dam, next upstream, was completed in 1959 replacing locks and dams 12 and 13. Raising crest dam 8 was also completed in 1959 as part of upper river improvement and eliminates restricted depth in upper reach of pool. Opekiska lock and dam, the final step in the replacement program, was completed in 1967 replacing locks and dams 14 and 15. Completion of this final link in upper river replacement program provides for entire river length of minimum channel depth of 9 feet, varying in width from a minimum of 250 feet to practically full width at mouth. Estimated cost for new work (1970), exclusive of amounts expended on previous projects is $122,500,000. (See tables 25-B, 25- D, and 25-E for authorizing legislation and locks and dams on Monongahela River, Pa. and W. Va., and total costs of existing project to end of fiscal year.) Local cooperation. None required. Terminal facilities. City of Pittsburgh constructed a modern wharf for 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 general commerce. A number of docks and pipelines are also privately maintained for petroleum and acid products. Marine ways are maintained by some of the larger industries. There are also several terminals for rail-to-river and river-to-rail transfer. Facilities considered adequate for existing commerce. Operations and results during fiscal year. New work: Major items of work performed by contract and hired labor: Maxwell locks and dam: Remedial work to water line was completed at cost of $4,424; administrative work in connection with settlements on outstanding judgments continued at cost of $2,556. Total cost for Maxwell locks and dam was $11,672. Reconstruction of dam 4: Costs incurred in connection with acquisition of flowage easements amounted to $8, 729. Total cost for reconstruction of dam 4 was $12,473. Opekiska lock and dam: Costs incurred in connection with acquisition of land and flowage easements amounted to $1,789. Total cost for Opekiska lock and dam was $17,702. Operation and maintenance, general: Locks were operated as required and necessary repairs were made to structures to maintain them in a serviceable condition at cost of $1,482,444; maintenance repairs at locks and dam, including replacement of locomotive crane at Morgantown lock and dam, cost $529,460. Condition at end offiscalyear. Project is complete except for concluding acquisition of land and flowage easements in connection with reconstruction of dam 4 and the construction of Opekiska lock and dam and concluding administrative actions relative to outstanding judgments at Maxwell locks and dam project. A controlling depth of 9 feet is maintained for entire length of river, varying in width from a minimum of 250 feet to full width of river at mouth. 767 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 5. OPEN-CHANNEL WORK, OHIO RIVER. See this heading under Ohio River portion. 6. TYGART LAKE, W. VA. Location. On Tygart River in Taylor County, W. Va., about 22.7 miles above mouth of river at Fairmont, W. Va. It is 2.25 miles upstream from Grafton, W. Va., and about 78 miles south of Pittsburgh, Pa. Reservoir is in Taylor and Barbour Counties, W. Va. (See Geological Survey Charts for Fairmont, Thornton, and Belington, W. Va.) Existing project. A reservoir for low water regulation and flood control. Dam is concrete gravity type with an uncontrolled center spillway flanked by_ abutment sections joining valley sides. Project was authorized by Public Works Administration January 11, 1934, and adopted by 1935 River and Harbor Act. For further project description see Annual Report for 1962. Completed project cost $18,431,844. Local cooperation. None required. Operations and results during fiscal year. Operation and maintenance, general: Reservoir was operated for benefit of flood control and low water regulation, as required, and project structures were maintained in a serviceable condition throughout the year at cost of $142,375. Melting snow beginning on December 29, 1969 augmented by heavy rainfall on 29th and a mixture of rain and snow on 30th, caused a major rise in upper Monongahela River Basin and a minor rise in upper Ohio River at Pittsburgh, during which this reservoir achieved significant reductions. For this storm and flood crest stage reductions effected by this reservoir ranged from 6.5 feet at Maxwell locks and dam to 1.5 feet at Pittsburgh. Crest stage on Ohio River at Pittsburgh was 17.4 feet, 0.6 foot below damage stage. From this storm and flood reservoir reached elevation 1119.8, with a storage of 161,200 acre-feet or 54 percent of usable seasonable flood control storage. Rainfall on April 23-25, 1970 caused a major rise in upper Monongahela River Basin and a minor rise in upper Ohio River Basin at Pittsburgh, during which this reservoir achieved significant reductions. For this storm and flood crest stage reductions effected by this reservoir varied from 1.5 feet at lock 2, Braddock to 1.8 feet at Pittsburgh. Crest stage on Ohio River at Pittsburgh was 17.4 feet, 0.6 foot below damage stage. From this storm and flood the reservoir reached yearhigh elevation of 1122.4, with a storage of 166,900 acrefeet or 34 percent of usable summer flood control storage. Rapid melting of a 6-inch snow cover on January 24-26, 1970, augmented by rainfall on 29th- 30th, caused a moderate rise in upper Monongahela River Basin and a minor rise in upper Ohio River at Pittsburgh, during which this reservoir, in conjunction with other reservoirs in upper Ohio River Basin, achieved significant reductions. For this storm and flood crest stage reduction effected by this reservoir at Pittsburgh was 0.5 foot. Crest stage on Ohio River at Pittsburgh was 18.5 feet, 0.5 foot above damage stage. From this storm and flood reservoir reached elevation 1087.1, with a storage of 99,700 acre-feet or 32 percent of usable seasonal flood control storage. Rainfall on April 1-3, 1970, augmented by melting snow, caused a moderate rise in upper Monongahela River Basin and a minor flood in upper Ohio River at Pittsburgh, during which this reservoir, in conjunction with other reservoirs in upper Ohio River Basin, achieved significant reductions. For this storm and flood crest stage reduction effected at Pittsburgh was 0.5 foot. Crest stage on Ohio River at Pittsburgh was 25.6 feet, 0.6 foot above flood stage. From this storm and flood reservoir reached elevation 1092.5 with a storage of 108,700 acre-feet or 23 percent of usable seasonal flood control storage.

The project is complete. Power was generated from November 18, 1969 to April 13, 1970. From July 1 to November 17, 1969 and from April 14, 1970 to end of fiscal year no power was generated due to upper reservoir being drained to inspect leakage and make repairs. Operations and results during fiscal year. New work: Land acquisition and negotiation of settlements continued at cost of $738,330. Final settlements were made with State agencies in connection with relocation of highways in the amount of $271,000. Pre-award survey is being conducted on low bidder for construction of first phase of Big Bend recreation area. Operation and maintenance, general: Reservoir was operated for benefit of flood control, as required, and necessary repairs were made to structures and appurtenances at cost of $211,783. Rainfall on January 28-29 and on February 1-4, 1970, augmented by snowmelt, caused a moderate rise in upper Allegheny Basin and a minor rise in Ohio River at Pittsburgh during which this reservoir, in conjunction with other reservoirs in upper Ohio River Basin, achieved significant reductions. For this storm and flood crest stage reductions effected by this reservoir at Parker and at Pittsburgh were 0.6 and 0.65 foot, respectively. Crest stage on Ohio River at Pittsburgh was 18.1 feet, 0.1 foot above damage stage. From this storm and flood reservoir reached elevation 1310.0, with a storage of 382,200 acre-feet or 17 percent of usable seasonal flood control storage. Rain mixed with snow on April 1-3, 1970 caused a major rise in the upper Allegheny Basin and a minor flood in upper Ohio Basin at Pittsburgh during which this reservoir, in conjunction . ith other reservoirs in upper Ohio River Basin, achieved significant reductions. For this storm and flood crest stage reductions at Kittanning, Natrona and Pittsburgh, Pa. were 1.1 feet, 0.8 and 0.9 foot, respectively.

Reservoir is in Mercer County, Pa., and Trumbull County, Ohio. (See Geological Survey Chart for Kinsman, Ohio, and Shenango, Pa.) Existing project. A reservoir for flood control, low-flow augmentation, and recreation. Dam consists of a concrete gravity structure with gate-controlled outlet 778 PITTSBURGH, PA., DISTRICT works and an uncontrolled center spillway section. For further project description, see Annual Report for 1962, page 1230. Project was authorized by 1938 Flood Control Act. Estimated cost for new work (1970) is $39, 535,000 which includes $2,635,000 for future recreation facilities. Local cooperation. None required by law. Operations and results during fiscal year. New work: Acquisition of land and payment of damages continued at cost of $256,800; final payments on completed highway relocation contracts amounted to $262,200. Operation and maintenance, general: Reservoir was operated for benefit of flood control, as required, and necessary repairs were made to structures and appurtenances at cost of $167,559. Heavy rain on April 1- 2, 1970 caused a moderate rise in Shenango River Basin and a minor flood in upper Ohio River Basin. For this storm and flood crest stage reductions attributed to this reservoir at Montgomery and Pike Island locks were 0.1 foot each. From this storm and flood the reservoir reached year-high elevation of 899.2, with a storage of 52,900 acre-feet or 8 percent of usable summer flood control storage. Melting snow beginning on January 26, augmented by rainfall on the 28th-29th and February 2-3, 1970, caused a moderate rise in Shenango River Basin. From this storm and flood the reservoir reached elevation 899.0, with a storage of 52,100 acre-feet or 23 percent of usable seasonal flood control storage. However, no benefits were attributed to the reservoir on this rise since damage stages downstream would not have been reached under natural conditions. Estimated flood control benefits achieved by this reservoir for fiscal year were $161,000. Total flood control benefits for this reservoir through June 30, 1970 are $1,890,000. Regulated flows at Sharon, Pa., for 35 days during July and August 1969 and 10 days in June 1970 averaged 266 cubic feet per second, representing 163 percent of natural low flow. Thus, this reservoir achieved benefits from low water augmentation. Activities under reservoir management program comprising sanitation measures, conservation, land management, and operation and maintenance of public-use facilities were continued. Condition at end of fiscal year. Authorized project is essentially complete. Reservoir is in operation for low water regulation purposes in Shenango River valley below and for flood control as a unit of a coordinated reservoir system for protection of Shenango River valley and the Beaver and upper Ohio River valley, generally. Construction of dam was started in March 1963 and completed in May 1965. Of 1,021 tracts of land authorized for acquisition 1,013 have been acquired. 30. STONEWALL JACKSON LAKE, W. VA. Location. In Lewis County, northern West Virginia, on the West Fork River, which joins the Tygart River at Fairmont, West Virginia to form the Monongahela River. Damsite is located at Brownsville, West Virginia, about 4 miles south of Weston and 72 miles above mouth of West Fork River at Fairmont, W. Va. (See Geological Survey Charts for Weston and Crawford, W. Va.) Existing project. Provides for construction of a reservoir for flood control, water supply, water quality control, area redevelopment and recreation. Dam would be of the concrete gravity type, 95 feet high and 680 feet long. Outlet works will consist of four multi-level sluices, spillway will be uncontrolled. Storage capacity will be 75,200 acre-feet controlling an area of 102 square miles. Project was authorized by 1966 Flood Control Act. Estimated initial Federal cost for new work (1970) is $49,800,000 (includes $3,010,000 reimbursement by non-Federal interests). Local cooperation. Local interests are required to make arrangements for repayment, under provisions of the Water Supply Act of 1958, as amended, of that part of the construction cost and annual operation, maintenance and replacement costs allocated to municipal and industrial water supply, an amount presently estimated at $1,870,000 for construction; and $3,800 annually for operation, maintenance and replacements. Also, in accordance with the Federal Water Project Recreation Act, local interests are required to administer project land and water areas for recreation and fish and wildlife enhancement, pay, contribute in kind or repay (which may be through user fees) with interest, one-half of the separable first cost of the reservoir project allocated to recreation and fish and wildlife enhancement, an amount presently estimated at $1,140,000; bear all costs of operation, maintenance and replacement of recreation and fish and wildlife lands and facilities, the amount involved being currently estimated on an average annual basis to be $95,700; hold and save the United States free from damages resulting from water-rights claims due to construction and operation of the project; exercise to the full extent of their legal capability, control against removal of streamflow made available for water quality control; and contribute to the control of pollution of streams subject to low-flow augmentation by adequate treatment or other methods of controlling wastes at their source. The City of Weston desires inclusion of storage for present and future use for water supply purposes. The City also recognizes the responsibility of repayment to the United States of all costs allocated to its share of the total storage allocated to water supply and on April 6, 1970 adopted a resolution expressing willingness to pay its portion of costs allocated to water supply. Clarksburg interests recognize the need for assuring an adequate future supply of raw water for their area. Because of conflicts in determining the responsible parties or agencies to assume the responsibility of repayment to the United States of their share of costs allocated to water supply, no resolution has been received to date to allow this 779 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 storage to be included in the impending General Design Memorandum. The local water supply agency, Clarksburg Water Board, although supporting in general the project as proposed, does not for several reasons (riparian use of water quality flows, current indebtedness, widespread use and benefits) accept the conditions for repayment of allocated costs outlined in the Water Supply Act of 1958, as amended. Recent proposals by the Clarksburg City Council and Harrison County Commissioners to assume two-thirds of these costs conditional on Water Board participation has also failed to dislodge the Water Board from its position.

New Work: Work in connection with Section A of the Flint River Flood Control Project, which was substantially completed in July 1967, was performed at a cost of $8,960. The contract for replacement of the Stevenson Street Bridge was substantially completed in June 1968. However, the actual removal of the old bridge is not required until 180 days after completion of the contract for Section B. The contract awarded in June 1968, for floodwalls, interior drainage, excavation and paving Chevrolet Dual Bridge Section B was initiated and is approximately 82 percent complete, at a cost of $950, 242. Completion of Section B is tentatively scheduled for Fiscal Year 1971. At the request of local interests, construction of the upstream portion of Section C will be delayed and consequently the downstream portion of Section C will be constructed under the same contract with Section D. The downstream portion of Section C has been designated C-1 and the upstream portion C-2. The rescheduling will permit the redesign of C-2 to make it compatible with the plans of the city of Flint and the Department of Housing and Urban Development in the area. The city has engaged the services of an engineering firm to develop a preliminary plan for the flood control channel which will embrace both flood control criteria and urban renewal concepts. Three alternative plans will be developed by the engineering firm and included in a letter report for the redesign of C-2 to be completed in fiscal year 1971. Negotiations between the city and the Chesapeake and Ohio Railway Company to purchase the C&O bridge and approach trackwork in connection with the urban renewal program in Section C-2 are nearing completion. Negotiations leading to relocation agreements with the Grand Trunk Western Railroad, in Section C- 1, and the Chesapeake and Ohio Railway in Section D, continued. Preparation of the scheduled feature design memorandum and efforts towards advertising federal project features in Sections C-1 and D continued for Flint. An 8,000 gpm standby pump will be provided in the existing project interior drainage pump station at Frankenmuth in fiscal year 1971. A $14,000 reimbursable contract was executed with the city of Frankenmuth for alteration of the pump facility by the city. Preconstruction planning costs for Flint, Frankenmuth, Midland, and Shiawasee Rivers were $160, 021, $1,813, $59,320, and $16,696, respectively. Surveys, construction layouts, supervision and administration for Flint River Sections A and B cost $106, 012. Condition at end of fiscal year. Construction at Frankenmuth was completed in 1967. Section A of the Flint project was completed in 1967 and the Stevenson Street Bridge was completed in 1968. Section B was initiated in 1968 and is scheduled for completion in fiscal year 1971. In view of excessively high bidding, the Government plan for alteration of the Chevrolet spur track will be restudied and readvertised in fiscal year 1971. 47. SEBEWAING, SEBEWAING RIVER, MICH.

COLLECTION AND STUDY OF BASIC DATA The Flood Plain Management Services (FPMS) Unit within the Detroit District is responsible for the flood plain management program which includes; (1) the provision of services and guidance in flood plain management activities, (2) the preparation of flood plain information reports, and (3) the provision of technical services to Federal agencies in compliance with Executive Order 11296 and to State and local agencies, and (4) comprehensive flood damage prevention planning. a. Flood Plain Management Services Unit: Numerous contacts were made with officials of Federal, state and local agencies and private organizations to press the importance of flood plain management acitivities and the techniques of their application. Special technical services were provided in response to numerous requests to satisfy immediate critical needs. FPMS program literature and completed flood plain information reports were transmitted to representatives of local and State governments, various consultants, libraries and interested organizations as well as concerned citizens. Conferences and discussions were conducted with the coordinating agencies for the states of Ohio, Indiana and Michigan as well as municipal consulting engineers and planners, representatives of the private sector to include land developers and housing specialists and their attendant legal and economic specialists. With the application and distribution of flood plain information reports, assistance was given in the adoption of flood plain zoning ordinances. During the Fiscal Year 1970, close cooperation was maintained with the Bureau of Water Managements, Michigan, Ohio and Indiana Departments of Natural Resources, those state agencies designated as the coordinating offices responsible for establishing priorities for flood plain information reports and administering and policing enabling legislation. For Michigan these are Acts 167 and 288. Representatives of these agencies assisted with local authorities, in the formal presentation of completed FPI reports at public hearings. These included the Grand River, Ingham and Eaton Counties; Grand River, Lansing; and the Lookingglass River, Michigan. Continuing FPI report studies include the Middle, Upper, and Lower Rouge, the Clinton River, Oakland County, Michigan and the Maumee River, Napoleon and Defiance, Ohio. The 920 DETROIT, MICH., DISTRICT total cost for the completed studies was $149,000. For the continuing studies the total expenditures to date are $245,116.00. The technical services effort has elicited increased interest particularly with respect to the support of Federal agencies and compliance with Executive Order 11296. These involve 14 for HUDFHA, 8 for EDA, 3 for Post Office, 9 for GSA, and 5 for state agencies. Technical support was also given to 6 communities, and 26 consultants and individuals. A special effort was put forth in assisting the City of Southfield, Michigan, with the preparation of flood plain zoning ordinance. This entailed numerous meetings and inspections with consultants and representatives of various conservation groups. Comprehensive flood damage prevention planning, treatment of nonstructural alternatives relating to survey investigations and reports were continued for the Manistique and Indian Rivers, Michigan, and the Maumee River Basin, Indiana and Ohio. Basic data relating to resolution of flood problems were collected and investigations completed. Efforts were made to determine feasible and appropriate corrective measures. Total cost was $2,345. 921 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 TABLE 30-A See Section in Text Project 1. Alpena Harbor, Mich. 2. Au Sable Harbor at Au Sable River (Oscoda), Mich. 3.

In addition, contiguous Canadian areas are included where essential to integrity of charting and other activities. IMPROVEMENTS Navigation Page 1. Survey of North Central lakes. ............ 1.979 2. General Investigations Page Examinations and surveys. ................... 983 NAVIGATION 1. SURVEY OF NORTH CENTRAL LAKES Location. Region in which operations'are conducted lies within States of Vermont, New York, Pennsylvania, Ohio, Michigan, Indiana, Illinois, Wisconsin, and Minnesota. For additional details see Annual Report for 1962. Previous projects. In the region described, previous projects of Lake Survey have specified provision of complete navigation charts designed to suit needs of existing use of waters. These projects, in addition to hydrographic and topographic surveys, contemplated establishment of requisite horizontal and vertical control where not already in existence, and measurement and analysis of other factors pertaining to navigation. A comprehensive statement concerning prior projects on the Great Lakes, and formulation of "a general project covering to completion the operations of the Survey" appeared in Annual Report for 1907, pages 844 to 850. Responsibilities under prior projects in Great Lakes portion of the region covered, apart from charting and navigational aspects, consisted of those pertaining to lake levels, hydrology, and hydraulics of connecting and outflow rivers. The 1907 Annual Report, referred to above in connection with charting and navigational portions of the project, also discussed prior and existing responsibilities in these respects. A board appointed by the Division Engineer, Great Lakes Division, to study and clarify U. S. Lake Survey activities in this second category formulated a report which included definite recommendations. The board report was presented to the Chief of Engineers and approved January 21, 1935, as basic description of such responsibilities. Existing project. Portion of existing project concerned with charting provides for general maintenance of chart coverage. Various classes of charts are issued consisting essentially of general charts employing small scales; coastal, river, and sectional charts employing medium scales; harbor and confined locality charts employing large scales; and special charts such as those for recreational use employing scales suitable for purposes intended. Number of charts and individual chart scales and coverages are not fixed, project being made purposely flexible to permit alterations to keep abreast of changing needs. Essential to charting, and pertinent to lake levels and hydraulics as well, is the portion of project relating to maintenance of horizontal and vertical control coverage. Original control was established under early projects in connection with initial surveys by U. S. Lake Survey on the Great Lakes and by other Government agencies in other areas of the district. Original control has been preserved wherever possible; where destroyed, it has been replaced as needed; and where necessary, it has been augmented by additional control for use in connection with later surveys and other Corps work. Project includes publications with information for benefit of navigation in addition to that provided by charts. These consist of such publications as the Great Lakes Pilot and supplements thereto and various lake and river level bulletins. The Pilot, issued annually, supplies full descriptions of physical conditions of waters charted and particulars of constantly changing conditions not adapted to adequate or prompt representation on charts. The supplements, issued monthly during the Great Lakes navigation season, provide corrections and additions to the Pilot. Lake and river level bulletins permit maximum utilization of navigational depths in Federal projects and elsewhere. Since 1859, lake level gages installed and operated by U. S. Lake Survey have provided a continuous * All cost and financial statements for projects are listed at the end of this chapter.

Present project provides for continued operation of a comprehensive gage network. In the fields of applied hydraulics and hydrology, present project provides for continuing studies of all aspects thereof required for discharge of Corps of Engineers responsibilities on the Great Lakes. In addition to the foregoing, the Lake Survey Great Lakes Research Center makes scientific investigations of all aspects of fresh-water oceanography relating to development and utilization of water resources of the Great Lakes system, in conjunction with which field surveys and observations are accomplished, data collected and analyzed and reports published. For additional details of existing project, see Annual Report for 1962. Operations and Results during Fiscal Year. The following paragraph contains a narrative summary of Lake Survey activities on the Great Lakes in the fields of hydraulics and hydrology, hydrographic surveys, chart printing, research and related phases of this District's mission. ENGINEERING. Hydraulics and Hydrology. The computation required to reduce the following discharge measurement have been completed and reports thereon started: 1967 Discharge Measurements, Tonawanda Section, Niagara River; 1968 Discharge Measurements, Bay Point Section, St. Clair River; 1968 Discharge Measurements, Roberts Landing Section and Flow Distribution in St. Clair River; 1969 Discharge Measurements, and Flow Distribution, St. Marys River below rapids; 1968 Discharge Measurements, Fort Wayne Section, Detroit River; 1969 Discharge Measurements, Control Structure, St. Marys River. Adaptation of Van Karman's equation for obtaining the vertical velocity distribution along with the transverse velocity coefficient, determination was incorporated in a computer program for reducing velocity measurements into discharge. During January 1970, discharge measurements were made in the Chicago Sanitary and Ship Canal at the request of the Metropolitan Sanitary District of Chicago. The measurements are now being reduced and will be used to check the accuracy of the Sanitary District's Leading Edge Sonic meter used for continuously meaSring the discharge. Simultaneous measurements of discharge in the North Cornwall channel by the Water Survey of Canada and the total river flow at Massena Point below the power houses by the Lake Survey were completed during May 1970. These measurements requested by the Seaway Authority will serve to evaluate the distribution of flow in the North Channel. A Miscellaneous Paper 70-1, "Color-Velocity Method in Measuring Discharge," was published. This report discussed the application of fluorescent dyes in measuring discharge. (Note that the foregoing operations do not include certain operations conducted specifically for international boards and committee. These operations are described later in a separate section herein. Note, however, that some of the foregoing operations are pertinent to the work of the international groups as well as to the basic Lake Survey mission.) Hydrographic Surveys. Hydrographic surveys were begun on the St. Clair River. These surveys are required for updating of charts of this area and for measurements of specific cross section of the main river and the North, Middle and South Channels in support of a hydraulic study of the river. Horizontal control was established where needed in this area and near Toledo, Monroe and Port Dolomite. Revisory surveys were completed on Lakes Huron and Superior, Lake of the Woods and Rainy Lake, and along the St. Marys River. Revisory surveys were started on Lake Erie. Surveys required for the maintenance of vertical control at harbors and gage sites along these waters were accomplished. Sixty-six special water-level gages, established earlier in selected harbors on Lakes Superior, Huron, and Michigan were continued in operation through September 1969. These gages are required to obtain data for verifying or establishing vertical control at these harbors. Fifty-one similar gages were installed at harbors on Lakes Michigan, Huron, Erie, and Ontario in May 1970. Field work for the re-evaluation of International Great Lakes Datum (1955) was continued with levels of special accuracy along portions of the St. Lawrence, Detroit and St. Marys Rivers. Chart Printing. Forty-eight Lake Survey charts were printed; consisting of 28 new editions, 16 reprints, and 4 recreational series charts of which 3 were reprints, for a total of 139,503 copies. In addition, 81,875 copies of the Lake Survey Monthly Bulletin of Lake Levels were printed, together with 46,000 copies of Lake Survey's chart catalog. Work for other Districts consisted of 35 Status Maps, 205 Project Maps, 43 Flood Plain Maps, 24 miscellaneous maps, and 77 Illinois Waterway charts, 11 flood reports and brochures for a total of 1, 045,928 copies. GREAT LAKES RESEARCH CENTER. Water Motion. Work accomplished in the various continuing projects of this field included studies and a report on harbor currents at Toledo, Ohio and Harbor Beach, Michigan; deep-water wave measurements at Eagle Harbor, Whitefish Point, Point Betsie, and Grand Haven, Michigan and Lorain, Ohio, and shallow water wave characteristics measurements at Pentwater, Michigan. A report on harbor and nearshore currents has been prepared. Energy transfer at the air-water interface is being studied using data from the research tower near Muskegon, Michigan. Shore Processes. Work was completed and a paper published on the littoral transport and energy relationships, using the data recorded and measured in lower Lake Huron and St. Clair River. In support of the planned extensive subbottom investigations in 980 U. S. LAKE SURVEY Lake Erie, a map summarizing the current knowledge of the lake's bottom sediment distribution is being prepared. Water Characteristics. For determination of water characteristics in Lake Superior, 11 cruises were conducted in the western portion of Lake Superior between 8 May and 7 November 1969. Data were reduced on Lakes Erie, Huron and the eastern portion of Lake Superior water and bottom characteristics. A data report for Lake Erie was largely completed. Water Quantity. Studies were completed on methods for determining overwater precipitation from the overland records on Lake Michigan. Reduction of climatological data from Lakes Michigan and Erie continued. Preparation of comprehensive texts on the limnology and hydrometeorology of the Great Lakes was initiated in response to a request from the Great Lakes Basin Commission. A mathematical modelingsystems analysis program for Great Lakes water resource planning was also initiated. Ice & Snow. The extent and characteristics of ice cover on the Great Lakes were recorded by visual observations and photomappings in ice charting, 8 aerial reconnaissance flights were made which resulted in 23 ice charts, and in aerial photomapping, 2,500 miles at an altitude of 23,000 feet were flown. Aerial photomapping flights of the lakes and Whitefish Bay and the St. Marys River were flown by the U. S. Air Force. Reports titled "A Literature Review of Dusting Techniques" and "Great Lakes Ice Atlas" were published. International Hydrological Decade. In addition to its continuing Great Lakes research mission, the Lake Survey was designated by the Chief of Engineers to administer the Corps of Engineers responsibility as Lead Agency for the International Hydrological Decade activities on the Great Lakes. These activities have been designated "International Field Year on the Great Lakes" (IFYGL). In coordination with the Steering Committee, four research contracts with universities were negotiated, and one project within the U. S. Geological Survey was funded. Instrumentation contract has been signed and work is in progress GREAT LAKES REGIONAL DATA CENTER Computer utilization was increased for reduction of data generated by Engineering and Research activities. Computer applications included statistical analyses of data on spoils disposal, water levels, water temperatures, ice and snow, and hydraulics and lake regulation. An accounting machine was installed for listing of punched cards for sight verification and editing to reduce processing costs of erroneous data. International Activities. In addition to the International Activities reported above under Operations and Results during Fiscal Year, the following operations were conducted specifically for international boards and committees. International Joint Commission. The District Engineer and members of his staff attended the October 1969 and April 1970 appearances of the Great Lakes Boards before the International Joint Commission.

The District Engineer and/or members of his staff attended ten meetings of the Regulation Subcommittee during the year. In addition, close liaison between personnel engaged in the studies for the Working Committee and the Board was maintained through frequent telephone discussions and exchanges of study material. The Regulation Subcommittee during the reporting period forwarded to the Working Committee letter reports on the completion of its optiminization and basic of comparison studies. The Subcommittee developed for the Board a CPM for the Great Lakes Levels Study. Currently under study are regulation plans for all of the lakes and for the Superior-Ontario combination. In conjunction with these studies, work continued on preparation of a report on the hydraulics and hydrology of the system. A report on consumptive use of water within the system, and a report on simulation of Great Lakes Basin water supplies and winter flow retardations was completed. A member of the staff attended nine meetings of the Regulatory Work Subcommittee. Regulatory Works Activities FY1970. The subcommittee completed a report on the 1968-69 winter gate tests at the St. Marys Control Structure, conducted similar tests during the winter 1969-70 and began preparing a report thereon. The Niagara Mathematical Model was documented and given to the Canadian Section on the Subcommittee for channel design studies on the Niagara River. A report on the Preliminary Foundation Investigation, Niagara River at Fort Erie for an alternate sit e location for a proposed control structure was completed by the Canadian section. The St. Clair Mathematical Model was completed, joined with the previously completed Detroit River model and operated for the development of preliminary channel designs. Discharge measurements and water levels were obtained for the basic data required for the St. Marys River Mathematical Model. Work on the computer program for this model and Hydrographic surveys for updating the cross sectional areas of portions of the St. Clair River were started. During the year, support was provided to the Shore Property Subcommittee through evaluation of regulation plans. The District Engineer and members of his staff attended three meetings of the Reports Subcommittee. The Subcommittee developed and issued a style and format manual for the Board's final report. Coordinating Committee on Great Lakes Basic Hydraulic Data and Subcommittee. The Chief of the Engineering Division and members of the staff attended two meetings of the Committee with its Subcommittees during the year. Work of the Subcommittees was as described below.

CHANNEL ISLANDS HARBOR, CALIF. Location. On California coast, 65 miles northwest of Los Angeles Harbor and 345 miles south of San Francisco. (See Coast and Geodetic Survey Charts 5007 and 5202.) Existing project. A harbor for light-draft vessels, on coast of southern California about a mile northwest of existing harbor of Port Hueneme, and beach erosion control works. Ventura County, sponsor of project, requested modification of document plan of harbor improvement and submitted a modified plan that was approved and adopted by Chief of Engineers in 1957. The harbor, which provides facilities for berthing and servicing about 640 small craft and commercial fishing boats, includes an entrance channel 20 fee deep, 300 feet wide, and 1,650 feet long-protected by two parallel entrance jetties 1,270 and 1,300 feet long; an entrance basin 20 feet deep, 300 to 750 feet wide, and 1, 750 feet long; an inner basin 10 feet deep, 900 to 1,400 feet wide, and 1,200 to 2,000 feet long; and a side basin 10 feet deep, 100 to 250 feet wide, and 900 feet long. About 6,238,000 cubic yards of dredged material from entrance channel, interior basins, and sandtrap were deposited in feeder-beach area to restore downcoast shoreline. A 2,300-foot-long offshore breakwater was placed to form a sandtrap in conjunction with jetties. About 2,000,000 cubic yards of material are to be dredged each biennium from sandtrap formed by jetties and breakwater. This material will also be deposited along the downcoast shoreline as long as the area remains under Federal ownership and requires beach erosion control. Plane of reference is mean lower low water. Range between mean lower low water and mean higher high water is 5.4 feet. Extreme range is about 8.5 feet. Federal first cost of new work on project as modified was $5,123,345 (excluding $1,361,668 Navy funds and cost to Coast Guard for installation of aids to navigation). Existing project was adopted by 1954 River and Harbor Act (H. Doc. 362, 83d Cong., 2d sess.). Map of modified plan is in "Design Memorandum No. 1, General Design for Harbor and Shore Protection Works Near Port Hueneme, California," prepared by Los Angeles District in May. 1957. Local cooperation. Fully complied with. Terminal facilities. A 4-lane launch ramp and 2 public docks for outboard motorboats; paved parking for 125 car trailers; dry storage for 200 boats on land, 800 boats in slips in 3 marinas, with restroom and shower facilities; 3-ton hoist; boat-repair facilities, with a 35- ton hoist (yard and boatways for boats up to 100 tons, including facilities for repairing and manufacturing boats up to 75 feet long); fueling facility; sport-fishing facilities; and 3 restaurants. There are 240 marina apartments, with 200 adjoining slips, 90 motel units, 2 yacht club buildings, and a harbor administration building. A yacht club, with 90 apartments and 50 boat slips, is scheduled for completion by the end of 1970. A private marina development, immediately north of Channel Islands Harbor, plans to construct 350 waterfront homes, with docking facilities, during the next 12 months. Included will be a 4-lane bridge, with a span about 34 feet above sea level, for boats traversing the harbor to the marina development. Operations and results during fiscal year. Current biennial dredging was completed at a cost of $946,812 regular funds and $230,280 Navy funds. In addition, a reconnaissance and condition survey was conducted at a cost of $1,050. Condition at end of fiscal year. Construction was started in February 1959. Construction of north and south jetties was completed in June and September 1959, respectively. Construction of detached breakwater was completed in October 1960. Original harbor dredging was completed in August 1961. Current biennial dredging was completed in January 1970. Contract for maintenance dredging was awarded late in June. 2. DANA POINT HARBOR, CALIF. Location. On Pacific coast in southern part of Orange County, about 40 miles southeast of Los Angeles and Long Beach Harbors, 60 miles northwest of San Diego Harbor, and 17 miles southeast of Newport Beach Harbor. (See Coast and Geodetic Survey Chart 5101.) Existing project. Plan as modified provides for establishm ent of a harbor at Dana Point to accommodate 2,150 small craft and to serve as a harbor of refuge for light-draft vessels; an entrance channel 600 feet wide, 1,600 feet long, and 15 to 20 feet deep; a main channel 350 feet wide, 3,300 feet long, and 15 feet deep; an east channel 250 feet wide, about 1,100 feet long, and 12 to 15 feet deep; an anchorage area 350 feet wide, about 600 feet long, and 12 to 15 feet deep; a west channel and turning basin 450 feet wide, 900 feet long, and 10 feet deep; a west breakwater 5,500 feet long; and an east breakwater 2,250 feet long. Plane of reference is mean lower low water. Range of tide 986 LOS ANGELES, CALIF., DISTRICT between mean lower low water and mean higher high water is 5.3 feet. Extreme range is about 10.7 feet. Latest approved estimated (1967) first cost for project is $9,200,000, comprising $4,604,000 Federal (including $24,000 for Coast Guard costs) and $4,596,000 non- Federal. Existing project was adopted by 1962 River and Harbor Act (H. Doc. 532, 87th Cong., 2d sess.). Authorized project was modified by Design Memorandum No. 1, approved in February 1966, which contains a map of modified project plan. Local cooperation. Local interests must contribute in cash 50 percent of the first cost of construction of general navigation facilities; provide lands and rightsof- way for construction and future maintenance of the project and of aids to navigation upon request of Chief of Engineers, including suitable spoil-disposal areas and necessary retaining dikes, bulkheads, and embankments therefor or cost of such retaining works; hold the United States free from damages; provide and maintain adequate service frontage and public landing with suitable supply facilities, necessary mooring facilities and utilities, and access roads, parking areas, and other necessary public-use shore facilities, open to all on equal terms; first phase of development to be completed within 5 years, and full development within 15 years, after completion of general navigation facilities; operate a general anchorage area or mooring facilities with reserved spaces adequate for transient boat traffic and for refuge, open to all on equal terms; dredge berthing areas commensurate with depths of Federal channel improvements; and secure and hold in the public interest all lands bordering development to a width sufficient for proper functioning of harbor. Terminal facilities. Since 1956, Orange County Harbor District constructed the following improvements at Dana Point: A paved access road from top of bluff to cove; about 2 acres of filled land protected from wave action by stone revetment; a 300-foot-long concrete pile-trestle pier; public restroom and parking facilities; a concrete launching ramp for trailered boats; 14,000 linear feet of quay wall; and 5,500 linear feet of rockrevetted slope; created 102 acres of level land support area; and deepened 78 acres of water area for boat basins. The Orange County Harbor District is in the process of extending water, sewer, electric power, gas, and cable TV service to all land areas. Operations and results during fiscal year. Administered right-of-way acquisition continued by local interests. In addition, a reconnaissance and condition survey was conducted at a cost of $825. Condition at end of fiscal year. Breakwater construction was completed in October 1968. Work remaining consists of dredging of general navigation channels and completing administration of right-of-way acquisition by local interests, as required. 3.

SANTA BARBARA HARBOR, CALIF. Location. On Pacific coast, 90 miles northwest of Los Angeles Harbor and 320 miles southeast of San Francisco Harbor. (See Coast and Geodetic Survey Chart 5261.) Existing project. Maintenance dredging of depths existing in 1934 in harbor formed by breakwater constructed by local interests. Maintenance by means of a fixed sand-intercepting plant to be provided and operated by and at expense of local interests is permitted, the United States to make available for operation of the plant not exceeding $30,000 annually, whenever funds are allotted for such purpose, provided that there shall be deducted from such funds the actual cost of harbor maintenance found necessary if and when intercepting plant has been installed. Modification was authorized by 1962 River and Harbor Act (H. Doc. 518, 87th Cong., 2d sess.). See Annual Report for 1969 for detailed description. Plane of reference is mean lower low water. Range of tide between mean lower low water and mean higher high water is 5.4 feet. Extreme range is about 10 feet. Latest approved estimated (1969) first cost for project as modified is $6, 810,000, comprising $3,480,000 Federal (including $40,000 for Coast Guard costs) and $3,330,000 non- Federal (including cash contribution of $3,320,000). Prior to adoption by Congress, work was authorized by Public Works Administration. (See table 33-B for authorizing legislation.) Local cooperation. Under plan for existing project, no specific local cooperation is required. However, $462, 986 non-Federal funds made available by local interests were spent as follows: $450,322 to cover excess cost of depositing dredged material on the beach over estimated cost of similar dredging with disposal at sea; and $12,664 for dredging near pier formerly owned by the Navy. City of Santa Barbara entered into a contract with the United States to substitute, in lieu of fixed sand-intercepting plant, a movable dredge to work within protected area to shape the shoal resulting from travel of sand around breakwater so as to provide added protection within harbor and to pump surplus sand and future accretions from harbor area to downcoast beaches. The city will provide and operate a dredge of sufficient capacity to maintain an entrance channel into harbor with a minimum depth of 15 feet and a minimum width of 300 feet. Subject to availability of operation and maintenance funds, the United States will reimburse the city on or before June 30 of each fiscal year not more than $30,000 toward actual cost of condition surveys and operation of dredge. This contract, dated March 6, 1956, was executed March 22, 1956, to be effective July 1, 1956. Under plan to modify existing project, local interests must give assurance they will hold the United States free from damages; provide and maintain necessary mooring facilities and utilities, including a public landing with suitable supply facilities open to all on equal terms in accordance with plans approved by the Chief of Engineers, first phase of development to be completed within 5 years after completion of general navigation facilities and full development to be completed within 15 years; provide or arrange for suitable marine-repair facilities; secure and hold in the public interest all lands bordering development to a width sufficient for proper functioning of harbor; bear any additional cost for replenishment of beach sands east of harbor over those costs required for maintenance dredging of general navigation features; contribute in cash 49 percent of construction cost; provide lands, easements, and rights-of-way for construction and future maintenance, including suitable spoil-disposal areas and necessary retaining dikes, bulkheads, and embankments therefor or cost of such retaining works; repair and seal existing west breakwater in accordance with plans approved by the District Engineer, and subsequent thereto transfer ownership of breakwater to the United States; construct sand fillet east of harbor concurrently with construction of east breakwater to assure continued replenishment of beach sands to downcoast beaches; and remove a portion of Stearn's wharf and make such other alterations or relocations required for navigation improvements. Terminal facilities. A wharf 2,200 feet long, a pier 335 feet long, a landing float, an open mooring and slip anchorage for small craft, and a launching ramp for small craft. The wharf, which is equipped with loading facilities and facilities for small-craft repair, is used for general cargo and servicing fishing and oil-exploration boats. The pier, which was constructed by the Navy, is now operated by City of Santa Barbara and used for servicing pleasure craft and light commercial boats. Facilities are adequate for existing commerce. Operations and results during fiscal year. Condition surveys and maintenance-dredging reports submitted by City of Santa Barbara were audited. City of Santa Barbara was reimbursed $30,000 under terms of maintenance-dredging contract. Work on modified project plan was reclassified to "inactive" category because of lack of local support. Condition at end of fiscal year. City of Santa Barbara submitted evidence that it has maintained an adequate entrance channel into harbor. Work on modified project plan is inactive. 11.

Noyo Harbor is a cove on California coast about 87 miles south of Humboldt Bay and 135 miles northwest of San Francisco. Noyo River rises in Coast Range Mountains, flows westerly, and empties into Noyo Harbor. (See Coast and Geodetic Survey Chart 5703.) Previous projects. For details see page 1680, Annual Report for 1929, and page 1772, Annual Report for 1930. 1027 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Existing project. Provides for two entrance jetties; an entrance channel into Noyo River 10 feet deep and 100 feet wide and channel in river 10 feet deep and 150 feet wide extending about 0.6 mile above mouth, thence connecting channel about 400 feet long to mooring basin of about 8.5 acres 10 feet deep on south bank of river. All depths refer to mean lower low water. Tidal range between mean lower low water and mean higher high water is 5.8 feet. Extreme range is about 11.5 feet. Cost of new work construction completed in 1931 was $184,000, exclusive of amounts expended on previous projects. Minor rehabilitation of jetties completed in 1961 cost $222,810 exclusive of $1,700 contributed funds. A 400-foot channel extension, mooring basin and connecting channel were constructed by Noyo Harbor District in 1968. Breakwater portion of project is considered inactive. Cost of this portion, last revised in 1963, was estimated to be $13,830,000 Federal cost and $340,000 to be contributed by local interests. (See table 34-B for authorizing legislation.) Local cooperation. Act of July 3, 1930, requires local interests provide spoil-disposal areas, royalty-free stone for construction and repair of jetties, and rights-of-way for transporting stone to jetties. These requirements fully complied with for work performed. Expenditures by local interests in meeting requirements, in constructing privately owned shore-side harbor facilities, and in constructing the mooring basin are estimated to be in excess of $3 million. Noyo Harbor District furnished assurances of local cooperation required by Act of July 14, 1960, but subsequently obtained an Economic Development Administration grant and State of California loan for local construction of the authorized mooring basin. A 400-foot extension of the river channel to the mooring basin will be Federally maintained. The mooring basin will be maintained by Noyo Harbor District. Terminal facilities. None in harbor proper. In river above harbor there are two piers and nine fishreceiving wharves; three boat fueling wharves; two boat building and repair plants; one boat icing plant; three marine ways; and a number of privately owned mooring facilities. These facilities, together with those provided in the new mooring basin are adequate fo r existing commerce. Operations and results during fiscal year. New work: Advance engineering and design classification of breakwaters to inactive status. Maintenance: Engineering and design including dredging survey by hired labor and 41,107 cubic yards of shoaled material removed from project channels under contract awarded in prior fiscal year. Condition at end offiscalyear. Project is complete except for construction of breakwaters in Noyo Harbor which is considered inactive. Mooring basin and connecting channel in river, constructed by local interests, was completed in October 1968. Jetties, rock removal and dredging entrance and river channels completed in 1931. Minor rehabilitation of jetties and north wall completed in September 1961. Total cost of existing project to end of fiscal year was $1,858,079, of which $450,987 was for new work, $1,182,582 for maintenance, and $224,510 for minor rehabilitation of jetties and north wall ($222,810 regular funds and $1, 700 contributed funds). 5. OAKLAND HARBOR, CALIF. Location. On eastern side of San Francisco Bay, opposite city of San Francisco. Inner harbor is between cities of Oakland and Alameda. (See Coast and Geodetic Survey Chart 5535.) Previous projects. For details see page 1979 of Annual Report for 1915, page 1755 of Annual Report for 1921, and page 1674 of Annual Report for 1938. Existing project. Provides entrance channel to Oakland Outer Harbor, 35 feet deep from deep water in San Francisco Bay and 800 feet wide across shoal southeast of Yerba Buena Island, narrowing to 600 feet at Oakland Mole; thence a channel and turning basin 35 feet deep and from 600 to 950 feet wide in outer harbor to Army base. Project also provides entrance channel to Oakland Inner Harbor, 35 feet deep and 800 feet wide at bayward end, narrowing to 600 feet wide at ends of Oakland jetties; a channel from ends of jetties 35 feet deep and 600 feet wide to west end of Government Island, with additional widening to within 75 feet of pierhead line in front of Grove and Market Street (formerly municipal) piers and along south side of channel from Harrison Street eastward to harbor-line point 119 in Brooklyn Basin; a channel 35 feet deep and 500 feet wide through Brooklyn Basin; for dredging 35 feet deep a triangular area about 2,700 feet long and maximum width of 300 feet at western end of Brooklyn Basin; a channel along north side of Brooklyn Basin 35 feet deep and 300 feet wide for 1,300 feet, thence 25 feet deep to a turning basin at east end of Brooklyn Basin 35 feet deep, 500 feet wide, and 1,200 feet long; a channel in tidal canal 35 feet deep and 275 feet wide from Brooklyn Basin to Park Street, thence 18 feet deep to San Leandro Bay; a total channel length of 8.5 miles from San Francisco Bay to San Leandro Bay. Project also includes parallel rubblemound jetties at entrance to inner harbor, north jetty 9,500 feet long and south jetty 12,000 feet long; three highway bridges across tidal canal, two of which (at Park Street and High Street) have been replaced by local interests. Railroad and highway bridges at Fruitvale Avenue are maintained and operated by the United States. All depths refer to mean lower low water. Range between mean lower low water and mean higher high water is 6 feet in outer harbor and 6.3 feet in inner harbor at Park Street Bridge. Extreme range is about 11 feet. Approved estimated cost for new work (1970), exclusive of amounts expended on previous projects, is $9, 238,000 of which $8,622,000 is Federal cost and $616, 000 to be contributed by local interests. Deepening 1028 SAN FRANCISCO, CALIF., DISTRICT tidal canal from 18 to 25 feet and Federal participation in reconstruction of Fruitvale Avenue Highway Bridge to be restudied and are excluded from foregoing cost estimate. Estimated cost of tidal canal deepening (1954) is $489,069. Restudy of Federal participation in reconstruction of Fruitvale Avenue Highway Bridge initiated with Operation and Maintenance funds. (See table 34-B for authorizing legislation.) Local cooperation. Act of January 21, 1927, requires that future maintenance by the United States of north channel in Brooklyn Basin be contingent upon removal by local interests of all sewers emptying therein, or, in lieu of such removal, upon contribution of one-half the cost of maintenance. This requirement has not been fulfilled. In compliance with a 1910 license issued by Secretary of War pursuant to provisions of act of June 25, 1910, local interests replaced bridges at Park Street and High Street and are operating and maintaining them. They operated and maintained a combined highway and railroad bridge at Fruitvale Avenue until 1942 when California Court of Appeals ruled that it was illegal for County of Alameda to use appropriated funds for sole benefit of a private corporation. Southern Pacific Railroad Co. operated trains over combined bridge until June 1951 when a separate railroad bridge, constructed for its use by the Federal Government, was placed in operation. (Railroad and highway bridges at Fruitvale Ave. are maintained and operated by the United States.) All other requirements have been fully complied with. Only fragmentary records are available of costs to local interests in meeting requirements of local cooperation. Recorded expenditures are in excess of $11 million. Act of October 23, 1962, requires that local interests provide lands and rights-of-way for construction and maintenance; hold the United States free from damages to wharves, piers, tubes, and other marine and submarine structures due to initial dredging and future maintenance; alter sewer, water supply, drainage, and other utility facilities; provide and maintain adequate public terminal and transfer facilities, open to all equally; deepen and maintain slips and berths; and if required furnish spoil-disposal areas including necessary dikes, bulkheads and embankments for initial dredging and future maintenance. State of California, on September 12, 1961, furnished assurances that it will hold the United States free from liability for damages to Posey and Webster Street Tubes due to initial dredging and subsequent maintenance. Terminal facilities. See Port Series No. 31, "The Ports of Oakland, Alameda, and Richmond, and Ports on San Pablo Bay, Carquinez Strait, and Mare Island Strait," revised 1962.

Most westerly branch of interconnecting tidal channels into which San Joaquin River divides in crossing its delta. It leaves main river 2.5 miles downstream from Mossdale State Highway Bridge, or 13.5 miles above mouth of Stockton Channel, and flows westerly and northerly 32 miles to its lower confluence with main river 23 miles above its mouth in Suisun Bay. Existing project. For description of improvement and authorizing act, see Annual Report for 1967. Total first cost for completed portion $26,785 ($23,185 was Federal and $3,600 non-Federal for lands, damages, and public landings). Uncompleted portion of project is considered inactive and excluded from foregoing cost estimate. Estimated cost of this portion $63,815, of which $62,815 (July 1954) was Federal and $1,000 non-Federal (1939) for lands, damages, and public landings. Local cooperation. Fully complied with for completed portion. Terminal facilities. Holly Sugar Co. refinery and terminal near Tracy has a large wharf and an unloading basin with three mechanical unloading and conveying units connecting with a warehouse; there is also a passing basin one-half mile downstream. There are about 100 private bank landings along project channels; some have sheds for storage. These are all privately owned and operated. Existing commerce does not indicate a need for provision of public landings. Operations and results during fiscal year. Maintenance: Condition studies and miscellaneous inspections and reports by hired labor. Dredging shoals in Doughty Cut to Sugar Canal by contract suction dredge, $14,014. Condition at end of fiscal year. New work was accomplished in fiscal year 1939 in Old River channel from its head in San Joaquin River to Grant Line Canal and in channels of Grant Line Canal, Crocker Cut, and Doughty Cut. Existing commerce does not indicate a need for completion of remaining channel construction. Channel is navigable all year. The two heads of navigation are at head of Old River in San Joaquin River, and at Holly Sugar Factory wharf, 2 miles north of Tracy. Controlling depths: From mouth of river to Orwood, 11 miles, 10 feet; thence to lower end of Grant Line Canal, 10 miles, 10 feet; thence; (a) to Holly Sugar Factory near Tracy, 7 feet (low-water season), or (b) to head of Old River in San Joaquin River, 5 feet (low-water season). All depths refer to mean lower low water. 2. SACRAMENTO RIVER, CALIF. Location. Rises in Trinity Mountains in north-central California, flows generally southerly about 374 miles and empties into Suisun Bay, an arm of San Francisco Bay, at Collinsville, Calif. (See Geological Survey topographic map of Sacramento Valley, Calif.) Previous projects. For details see page 1985 of Annual Report for 1915, and page 1708, Annual Report for 1938. Existing project. For description of Sacramento Deep Water Ship Channel, see Annual Report for 1969. Total first cost for completed portion was $43,932,000 ($39,560,000 Federal (Corps), $300,000 (Coast Guard) , and $4,072,000 non-Federal for lands and damages, including relocations) and excludes local interests' costs $10,741,000 (June 1963) for 30-foot deep water ship channel and 13-foot deep connecting canal basic terminal facilities required under terms of project authorization. Project also provides for a shallow-draft channel 10 feet deep at mean lower low water 150 to 200 feet bottom width, from Suisun Bay to Sacramento, Calif., 60 miles; a depth of 6 feet at low water between Sacramento and Colusa, 85 miles; a depth of 5 feet at low water between Colusa and Chico Landing, 50 miles; and such depths as practicable between Chico Landing and Red Bluff, 53 miles, a total distance of 248 miles. Estimated Federal cost (July 1970) of new work for shallow-draft river channel is $1,230,000. (See table 35-B for authorizing legislation.) (See table 35-C on tidal and flood conditions prevailing.) Local cooperation. Fully complied with for deep water ship channel project. None required on shallow-draft feature. Terminal facilities. Piers, wharves, and docks at Port of Sacramento for shallow-draft navigation are open-pile structures with timber decks, some of which are designed to meet extreme high waters at flood stages. All main wharves at Sacramento have rail connections. Three of above facilities are owned by city of Sacramento and remainder by private interests; all are privately operated. For full description see "Port and Terminal Facilities at the Ports of Stockton and Sacramento, Calif., 1962." Deep water terminal facilities comprise wharves and piers, administration and storage buildings, and belt railroad facilities. Majority of these facilities are owned and operated by Sacramento-Yolo Port District; remainder are privately owned and operated. Facilities are considered adequate for existing commerce. Operations and results during fiscalyear. New work, Deep Water Ship Channel: Engineering and design in connection with channel were completed. Initiated and completed additional stone protection, vicinity mile 16.0 to mile 23.6, Sacramento River, by contract, $108, 000. (See table 35-D for major items of work included in maintenance.) Condition at end of fiscal year. Construction of 7-foot shallow-draft channel below Sacramento was initiated in September 1899 and completed in 1904. Modified 10-foot shallow-draft channel up to Sacramento was initiated in fiscal year 1928 and completed in 1931. Shallow-draft channel above Sacramento began in 1052 SACRAMENTO, CALIF., DISTRICT April 1946 and new work is about 48 percent complete. Work remaining to complete shallow-draft portion of projects is provision of a 5-foot depth between Colusa and Chico Landing (50 miles). Comple tion of shallowdraft channel is indefinite. Construction of 30-foot deep water ship channel was initiated in July 1949; improvement dredging by continuing contracts resulted in provision of an operational facility for oceangoing vessels during June 1963. Bascule bridge was completed in April 1960, barge lock in August 1961, barge canal in November 1961, and entire deep water ship channel in June 1970. Controlling lowwater- season depths for shallow-draft channel were: From mouth of Cache Slough to Sacramento, 10 feet; thence to Colusa, 6 feet; thence to Sidds Landing, 3 feet; and thence to Red Bluff, head of navigation, 1.5 feet. Channel is navigable all year; however, there is no regular navigation above Colusa, 145 miles above river mouth. Deep-draft channel will have a controlling depth of 30 feet for deep-draft vessels after annual maintenance dredging. 3. SAN FRANCISCO BAY TO STOCKTON, CALIF. (JOHN F. BALDWIN AND STOCKTON SHIP CHANNELS) Location. On navigation channels extending from entrance to San Francisco Bay to Port of Stockton through San Francisco, Marin, Contra Costa, Solano, Sacramento, and San Joaquin Counties.

FLOOD CONTROL 9. BUCHANAN RESERVOIR, CHOWCHILLA RIVER, CALIF. Location. On Chowchilla River about 36 miles above its mouth and about 16 miles northeast of city of Chowchilla, Calif. (See Geological Survey quadrangles for area.) Existing project. Provides for construction of a 205-foot high rockfill dam to create a reservoir with gross storage capacity of 150,000 acre-feet for flood control, irrigation, recreation, and fish and wildlife. In conjunction with dam, project plan provides for about 5 miles of downstream levee and channel construction on Ash Slough to accommodate a project design flow of 5, 000 cubic feet per second within slough. Operation and maintenance of dam and reservoir will be responsibility of the Federal Government. Approved cost estimate (July 1970) for existing project is $19,370,000, of which $19,100,000 is Federal cost, including $1,140,000 for basic recreation facilities, and $270,000 non-Federal costs for lands and damages, including relocations for downstream levee and channel improvements. Local interests have contracted with Bureau of Reclamation for irrigation service. For future non-Federal reimbursement, see Local cooperation paragraph. Local interests have also, over a period of years, expended about $500,000 for construction of low levees and clearing downstream channels to provide some local flood protection in project area. This work is inadequate during major floods. Existing project was adopted by 1962 Flood Control Act (S. Doc. 98, 87th Congress, 2d sess., contains latest published map). Local cooperation. California officially adopted project by chapter 1203 of stat utes of 1963, and by chapter 1438 of those statutes authorized State Reclamation Board to furnish assurances that requirements for supplemental channel improvements will be met. With respect to the dam and reservoir, local interests must reimburse the Federal Government the portion of first cost and annual operation and maintenance costs allocated to irrigation functions of the project. These costs are estimated at 44.3 percent of the joint-use first cost and 41.9 percent of joint-use annual costs. Project authorization provides for project to be financially integrated into the Central Valley project of the Bureau of Reclamation. Irrigation repayment contracts were executed with the Chowchilla and La Branza Water Districts by the Bureau of Reclamation May 28, 1968. Local interests sponsoring any permanent pool in the reservoir for fish and wildlife or recreation must settle all claims for water rights pertaining to establishment and use of a permanent pool for these purposes. With respect to supplemental channel improvement work, section 3, Flood Control Act of June 22, 1936, applies. Local interests must also preserve, or restore and thereafter maintain, the other channels of Chowchilla River and Ash and Berenda Sloughs, from Buchanan Dam downstream to Chowchilla Canal, at capacities existing in 1960. Formal assurances for supplemental channel improvements have not been requested. Operations and results during fiscal year. New work: Plans and specifications for dam and appurtenances were completed. Acquisition of real estate was continued. Had the project been in operation, damages estimated at $100,000 from the January 1970 flood would have been prevented. Condition at end of fiscal year. Preconstruction planning is complete. 10.

LOWER SAN JOAQUIN RIVER AND TRIBUTARIES INCLUDING TUOLUMNE AND STANISLAUS RIVERS, CALIF. Location. (a) New Melones Reservoir: (See Improvement No. 35). (b) Tuolumne River Basin: Cherry Valley Reservoir-on Cherry Creek in upper Tuolumne River watershed, about 12 miles above junction with Tuolumne River, in northwest corner of Yosemite National Park, Calif. New Don Pedro Reservoir-on Tuolumne River, a tributary of San Joaquin River, in Tuolumne County, Calif., about 32 miles east of city of Modesto. (c) Lower San Joaquin River and tributaries: On lower reaches of San Joaquin River and of Stanislaus and Tuolumne Rivers. (See Geological Survey quadrangles of area.) Existing project. Tuolumne River Basin: A Federal contribution for flood protection to be afforded by local interests construction and operation of Cherry Valley and New Don Pedro Reservoirs for municipal water supply, power generation, irrigation, and flood control. Ultimately the flood protection will be derived from operation for flood control of at least 340,000 acre-feet of storage in New Don Pedro Reservoir. First phase of development by local interests was construction for municipal water supply, power generation, and other purposes, of Cherry Valley Reservoir in upper Tuolumne River watershed, completed in December 1955 for interim flood control storage. Second phase of development will be construction of New Don Pedro Dam on Tuolumne River. Improvement will comprise a rock and earthfill dam, 565 feet high, to create a reservoir capacity of 2,030,000 acre-feet for purpose of municipal water supply, power generation, irrigation, and flood control. Approved cost estimate (July 1970) is $74,636,000 comprised of $59,800,000 non-Federal cost; $14,464,000 Federal contribution, including payments totaling $9,000,000 made to local interests toward first phase; and $372,000 Federal engineering and administrative costs, including $236,000 expended for initial phase.

Project was modified to permit local interests to construct levees and channel improvements upstream from Merced River, where required, in lieu of acquiring flowage easements. This project is an integral unit of overall plan for flood control and other purposes on San Joaquin River and tributaries, and supplements reservoir units of overall plan involving flood control storage on Tuolumne and Stanislaus Rivers and in existing Friant Reservoir on upper San Joaquin River by providing required channel capacity for regulated flows. Cost estimate (July 1970) for existing project is $19, 410,000, of which $13,110,000 is Federal cost and $6, 300,000 non-Federal cost for lands and damages including relocations. Local interests constructed levee and channel improvement works in area adjacent to river above mouth Merced River in lieu of acquisition of flowage easements. Estimated cost of this work (July 1970) is $24,000,000. Left bank levee in Tuolumne River to Merced River reach is now considered active and is included in foregoing cost estimate. Existing project was adopted by 1944 Flood Control Act (H. Flood Control Committee Doc. 2, 78th Cong., 2d sess., contains latest published map); as modified by Public Law 327, 84th Congress. The 1944 Flood Control Act authorized $8 million for partial accomplishment of project. Further monetary authorizations of $2,500, 000, $5 million, $13 million, $2 million, $17 million, and $18 million were provided for this project by Public Laws 235 and 780, 83d Congress, and 85-500, 90-17, 90-483, and 91-282, making a total monetary authorization of $65,500,000 available. Local cooperation. Tuolumne River Basin: In consideration of a Federal contribution toward first costs of construction, local interests must construct, maintain, and operate New Don Pedro Reservoir allocating 340, 000 acre-feet of storage space therein for flood control, and operate such flood control reservation as prescribed by the Secretary of the Army. A contract was negotiated in 1949 with local interests, comprising City and County of San Francisco and Turlock and Modesto Irrigation Districts, whereby they agreed to provide the above flood control storage in New Don Pedro Reservoir when constructed in exchange for Federal contribution. Construction of Cherry Valley Reservoir, and provisions of interim flood control storage therein as well as in existing Don Pedro and Hetch Hetchy Reservoirs, provided about 75 percent of flood control requirements for overall development, and Federal payments totaling $9 million made to local interests for this first phase. Second and final phase consists of construction of New Don Pedro Reservoir, operation of the flood control reservation in that reservoir, and cessation of operation of upstream reservoirs for flood control. Local interests have initiated construction of New Don Pedro Reservoir; bond issues for project received overwhelming approval of voters in elections held in November 1961 in Modesto, Turlock, and San Francisco. Federal Power Commission issued a license for project March 10, 1964. The irrigation districts approved acceptance of the FPC license May 23, 1966. Main dam contract was awarded in August 1967. Lower San Joaquin River and tributaries: Assurances were accepted by District Engineer January 6, 1956. Local interests fully 1063 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 complied with requirements for all Federal work completed or under contract, and indicated they will be able to fulfill local cooperation requirements for remaining work as scheduled. Ninety seven miles of the project total of 103 miles of levee construction have been transferred to and accepted by the State. Expenditures by local interests toward fulfillment of these requirements through June 30, 1970, were about $6,144,719. State revised their plan to include a bypass in lieu of improvement of existing levees along upper river reaches, thereby eliminating about 175 miles of levee construction along main San Joaquin River. Completed State project included construction of about 193 miles of levees, along with 18 major bridges and 7 control structures. Work extends along San Joaquin River from mouth of Merced River upstream to about 45 miles below Friant Dam near Fresno. Total cost of this plan is estimated (July 1970) at $24,000,000. Operations and results during fiscal year. New work: Tuolumne River Basin, including Cherry Valley and New Don Pedro Reservoirs-Engineering continued on New Don Pedro.

Estimated Federal cost of recreation facilities for Pine Flat Reservoir, to be funded from Code 710 appropriations is $920,100 (July 1970) exclusive of recreation facilities previously provided at a cost of $13, 700. In addition, Federal cost of recreation facilities for Pine Flat Reservoir, funded from Public Works Acceleration Executive Act of 1962 appropriations, was $239,235 (July 1963), exclusive of recreation facilities provided from regular project and Code 710 funds. Operation and maintenance of dam and reservoir is Federal responsibility. Existing project was adopted by 1944 Flood Control Act (H. Doc. 630, 76th Cong., 3d sess., contains latest published map). Local cooperation. Local interests must reimburse the Federal Government for first costs allocated to irrigation functions of reservoir portion of project in accordance with reclamation law. Under provision of War Department Civil Appropriations Act of 1947, the Secretary of War, with concurrence of the Secretary of the Interior, determined allocation of cost to irrigation should be set at an amount not to exceed $14,250,000. In addition, local interests must pay 37.4 percent of annual maintenance, operation, and replacement costs of dam and reservoir allocated to irrigation function. Repayment contracts between Bureau of Reclamation and the local water users for the irrigation use of the reservoir were executed December 23, 1963. Bureau is administering the contracts in accordance with reclamation law; however, local interests are testing in court the validity of reclamation law in regard to the Pine Flat contracts. Prior to execution of the final contracts, the Bureau provided conservation water to local interests under an interim contract. Irrigation interests paid $10,502,527 for irrigation services through June 30, 1969. With respect to the downstream channel improvements, section 3, Flood Control Act of June 22, 1936, applies. Kings River Conservation District represents local interests; assurances were accepted November 20, 1959. Local interests have furnished all requirements for construction rights-ofway for construction of channel improvements required to date. Three concessionaires--one each at Lakeridge Marina (Deer Creek), Lakeview Marina (Lombardo's Fishing Village), and Trimmer Marina provided public-use facilities in accordance with lease agreements with the Secretary of the Army. Estimated cost of facilities installed by these concessionaires is $309,000. Fresno County developed public-use facilities on an 85-acre tract immediately downstream from dam for picnicking, camping, swimming, and playground activities, at an estimated cost of $88,500 under provisions of a license agreement. Forest Service operates a picnic area at upper end of reservoir and two campgrounds and a picnic area at sites along reservoir perimeter. Total cost of development of these sites is about $37,500. Licenses. License No. 1988, effective April 1, 1955, was issued by Federal Power Commission to Pacific Gas and Electric Co. for hydroelectric power development of North Fork Kings River by the company upstream from Pine Flat Reservoir. Under interim 1067 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Contract No. DA-04-167-eng-1182 with the Department of the Army, Pacific Gas and Electric Co. paid for storage of power water in Pine Flat Reservoir May 15, 1954, through March 31, 1955. Current Contract No. DA-04-16 7-eng-13 28 with the Department of the Army provides for storage of power water at the rate of 0.1375 per acre-foot; the contract covers April 1, 1955, through March 31, 2005. Total payment under these contracts through June 30, 1970, amounts to $2,200,774; these funds are paid to Sacramento District and deposited for return to the Treasury. Operations and results during fiscal year. New work, regular funds: Engineering and design continued, $49, 971. Miscellaneous minor work in connection with channel improvement continued by hired labor. Code 710 funds: None. Maintenance: Maintenance and operation activities continued with condition and operation studies at a cost of $71,107 and major maintenance costs as follows: dam and reservoir $69, 069; service facilities $29,362; and recreation facilities $74,657. Structures were maintained in serviceable condition. Runoff of Kings River above Pine Flat Dam was near normal for the year. Maximum storage of 998, 700 acre-feet on July 22, 1969, resulted from the extremely large April-July 1969 snowmelt season runoff. Maximum bihourly inflow to Pine Flat Reservoir was 19,200 cubic feet per second on January 16, 1970. Maximum outflow of 17,761 cubic feet per second occurred on July 1, 1969. Flood control releases from July 1, 1969, through August 4, 1969 totaled 622, 300 acre-feet during December 1969 and January- February 1970 flood control releases totaled 135,800 acre-feet. Water released for flood control totaled 758, 100 acre-feet for the year. Release of water for irrigation and spreading totaled 1,416,500 acre-feet. Project prevented an estimated $600,000 in damages from the January 1970 flood. Condition at end of fiscal year. Construction began in April 1947 and project is about 99 percent complete. Construction of main dam was initiated in January 1950 and completed in June 1954. Dam has been operating since February 1954 to provide flood protection for which it was designed. Recreation facilities for various recreation areas under Code 710 appropriation initiated in fiscal year 1960 are 42 percent complete. Work remaining consists of provision of minor channel improvements, and completion of recreation facilities in connection with overall development of reservoir area. 28.

COLLECTION AND STUDY OF BASIC DATA International water studies. The Columbia River Treaty between Canada and the United States relating to International Cooperation in Water Resources Development of the Columbia River Basin was signed at Washington, D.C. on January 17, 1961. Implementation of the Treaty by the Entities under the guidance of the Permanent Engineering Board and the Coordinating Committee has continued. An operating program has been agreed to and established for Canadian storage operation through June 1972. The Entities have established two permanent committees, a Flood Control Operating Committee and a Hydrometeorological Committee. All present International Task Forces are to be disbanded when the Flood Control Plan has been completed, except for portions affecting Libby project in Montana, and Mica project in British Columbia pending possible modification of the International Joint Commission Orders for Kootenai Lake. Costs during fiscal year were $84, 014. Flood Plain Information Studies. Field surveys and other means were used to collect basic flood data to compile channel cross sections, water surface profiles, stage hydrographs and flooded-area maps for inclusion in two flood plain information reports, both undertaken in fiscal year 1970. A narrative, including a description of the flood situation along each stream studied, was also prepared for publication in the reports. Of the two 1121 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 reports the following one, "Corvallis-Philomath Area, Oregon, Flood Plain Information Report-Willamette and Marys Rivers", is near completion, while the other is identified in table (37-P). Final preparation work was accomplished on two additional reports also listed as completed in table 37-P. Costs for flood plain information studies during the fiscal year were $149, 805. Total costs for collection and study of basic data were $233,819. 62. RESEARCH AND DEVELOPMENT Water quality investigation. Program of observing water temperatures and monitoring dissolved oxygen at key Willamette Basin reservoirs was continued with the Federal Water Quality Administration taking a less active part. The Fish Commission of Oregon is still active in monitoring specific projects where they have a definite fishery interest. A report on District Water Quality Activities during 1969 was submitted to higher authority by the North Pacific Division office. Stored water in Willamette reservoirs was released in substantial quantities during the summer 1969 to alleviate a fishery passage problem in the Portland Harbor caused by a deficiency in the dissolved oxygen level. The Portland District continued its financial assistance to a special river temperature investigation in the Lower Columbia River, a program to study the feasibility of using Columbia River water as a coolant for a nuclear power plant. The turbidity problem at Hills Creek Lake remains and the problem will be given further study. A special grant has been requested so that specialists from outside the Federal agencies can be brought in to study the problem as it has implications involving other storage projects being studied by this office. Hydrologic studies. Reservoirs temperatures, dissolved oxygen, and suspended sediment were analyzed, and procedures for making synthetic reservoir temperature studies are being refined. A consulting firm was retained to study a specific project for the purpose of enhancing the program. Programs for using the computer to make hydrologic studies are being expanded and refined. Authority to automate reporting hydrologic network in the Willamette Basin was requested by the North Pacific Division. The system when activated would eliminate the manual collection and processing of a vast amount of basic stream, reservoir and weather information collected daily throughout the basin. Procedures for maximization of benefits from storage projects continued to be investigated. Nitrogen resulting from excessive discharge through spillways is having an undesirable effect on fish life. A consulting firm was retained to study this ecology problem. Regional low-water flow frequencies are being studied. Civil Works Investigations. Testing of a panel with a i'8- inch-thick epoxy mortar surface coating which was installed in the Detroit Test Conduit (ES 825) in June 1969 was continued. After 234 hours of testing the 2:1 epoxy on the left side of the panel had eroded to a depth of 3/4 inch. Complete failure of the surface on the left side terminated the test after a total time of 262 hours. At this time the 3:2 epoxy on the right side showed no appreciable erosion. A second test panel with a 3/4-inch-thick epoxy mortar surface was installed and testing was begun on 30 July. The test program was terminated for the season on 12 September after a total test time on the second panel of 634 hours. At termination of the test, erosion on the left side of the panel (3:2 epoxy) had reached a maximum depth of 1-1/2 inches and the right side (2:1 epoxy) had eroded to a maximum depth of 1/8 inch. No tests were conducted in the Detroit Test Chute (ES 826) during the year. Work performed consisted essentially of necessary maintenance and planning for future tests. Computer programs. Continued with the utilization of programs to make water resource system analysis, flood forecasting, flood routings, and derivation of design floods. Also, computation of horizontal and vertical control in survey work and earthwork design is a continuing program. The use a standard engineering systems used on the IBM 360 Model 50 installed at the North Pacific Division is continuing. In addition, Fortran programs have been written in the Engineering Division in the fields of Structures, Economic Studies, and Water Control. Total research and development costs were $82,593. 1122 PORTLAND, OREG., DISTRICT TABLE 37-A COST AND FINANCIAL STATEMENT See Section in Text Project Funding FY67 FY68 FY69 FY70 Ji 1.

Construction started in September 1969 and was completed in October 1969. 3. BLACKFOOT RESERVOIR, IDAHO Location. On Blackfoot River in Caribou County, Idaho, about 40 miles southeast of city of Blackfoot. (See Geological Survey quadrangle sheets Paradise Valley, Cranes Flat, Portneuf, and Henry Fork location and surroundings in immediate vicinity of project). Existing project. Blackfoot Reservoir is owned and operated by Fort Hall Agency of Bureau of Indian Affairs, Department of Interior. Main dam which is 52 feet high, is a rockfill structure with a concrete core. China Hat Dam, an earthfill structure, closes an arm of reservoir near its upstream end to minimize storage loss due to seepage in pervious formation of that area. Existing main dam structure includes a 3,800-cubicfoot- per-second spillway on the right abutment and an outlet tunnel in left abutment with a capacity of 2,700 cubic feet per second. Reservoir has a usable storage capacity of 413,000 acre-feet at design maximum water surface elevation 6124. However, due to experience with seepage losses from southern end of reservoir, operating level has been limited to about elevation 6120, or about 340,000 acre-feet storage capacity. Water stored in reservoir is used to irrigate lands in Fort Hall Indian Reservation in vicinity of Blackfoot and south. Recommended modifications of the project would provide 38,000 acre-feet additional storage capacity for flood control. Modifications would permit operation of reservoir for flood control to a maximum water surface elevation of 6126. The spillway capacity would be increased to 15,800 cubic feet per second by lowering crest elevation from 6118.5 to 6111.7 and increasing spillway width from 52 feet to 93 feet. Spillway would be equipped with new gates. Outlet works would be modernized and rehabilitated for flood control operation. China Hat Dam would be raised 8 feet and Idaho State Highway No. 34 would be raised in grade for approximately 1/2 mile along with grade raising of two existing bridges. Recommended modification was authorized by Flood Control Act of 1962. Construction to be accomplished by the Corps, with continued operation of project by Bureau of Indian Affairs. Estimated Federal cost of proposed modifications (July 1970) is $2,790,000. Local cooperation. None required. Operations and results during fiscal year. Preconstruction planning continued throughout fiscal year. Condition at end of fiscal year. Modification of Blackfoot Reservoir project in interest of increased flood control for Blackfoot River Basin was first presented as a potential project in review report for Upper Snake River Basin dated 1961, which was prepared jointly by Walla Walla District and Regional Office of Bureau of Reclamation in Boise, Idaho. That review report was authorized by a Senate Resolution adopted March 19, 1954, which requested a review of House Doc. 531, 81st Congress, 2nd session, with particular reference to Upper Snake River Basin above Weiser, Idaho. In referenced review report, modification of Blackfoot Reservoir project was presented as one of the potential projects warranting early consideration for construction. Interim report on modification of Blackfoot Reservoir, dated March 1962, included additional information and analysis of February 1962 floods and confirmed project economic feasibility. It is on this latter report that congressional authorization is based. Hydrology and general design memoranda have been approved. Action is pending on approval of real estate design memorandum and a supplement which have been submitted. Preparation of a feature design memorandum is in progress and is scheduled for publication in October 1970. 4. CATHERINE CREEK LAKE, OREG. Location. On Catherine Creek about 8 miles above Union, Oregon, in Section 7, Township 5 South, Range 41 East, Willamette Meridian. Existing project. Dam will be an earth embankment with an impervious core protected by sand and gravel filters. Shell material will consist of granular fill covered with substantial zones of rockfill on outside surfaces. Upstream face will be protected by riprap. Effective height will be about 197 feet and crest length 790 feet. A spillway will be in a saddle in left abutment about 1,000 feet from dam. Spillway will have three 15- by 18.5-foot tainter gates having a capacity of 11,740 cfs. Lake will contain 61,000 acre-feet of water with 58, 000 acre-feet of usable space at elevation 3440. Improvement will provide for flood control, irrigation, municipal and industrial water supply, water quality control, fish and wildlife, recreation, and downstream hydroelectric power. Project was authorized by 1965 Flood Control Act. Estimated Federal cost (July 1970) is $11,500,000. Local cooperation. The Water Supply Act of 1958 as amended applies. The city of Union, Oregon, by letter dated September 27, 1961, has provided assurances of willingness and ability to meet requirements. Reimbursable costs are presently estimated to be $349,000 for construction and $1,000 annually for operation, maintenance, and replacement. The Federal Water Project Recreation Act of 1965 applies. This requirement for loca 1 cooperation was added after submittal of the Survey Report. Negotiations are now underway to obtain a letter of assurance from a responsible non-Federal public body. Reimbursable costs are estimated to be $355,000 for construction and $47,600 annually for operation, maintenance, and replacement. In accordance with reclamation law, local irrigation interests will be required to repay portion of first costs and annual operation, maintenance, and replacement costs of dam and reservoir allocated to the irrigation function, currently estimated at $1,561,000 and $12, 300, respectively. Portion of construction cost beyond ability of irrigators to repay will be returned to reclamation fund from revenues derived from dis- 1176 WALLA WALLA, WASH., DISTRICT position of power marketed through the Bonneville Power Administration. Irrigation districts are to contract for repayment of cost allocated to irrigation. Operations and results during fiscal year. Preparation of a hydrology design memorandum and a general design memorandum progressed. Flood regulation studies and scoping studies continued in coordination with the Bureau of Reclamation, Federal Water Quality Administration, and other agencies. Mapping was completed and foundation explorations were continued. Condition at end of fiscal year. Preconstruction planning is approximately 55 percent complete. 5. COLUMBIA RIVER BASIN, LOCAL FLOOD PROTECTION PROJECTS Location. Improvements included in this project are along Columbia River and its tributaries. Existing project. Flood Control Act of 1950 approved a general comprehensive plan for Columbia River Basin for flood control and other purposes (H. Doc. 531, 81st Cong., 2d sess.) and authorized $75 million to be appropriated for partial accomplishment of certain projects. Of this authorization, not to exceed $15 million was authorized for construction of local flood protection works throughout Columbia River Basin, subject to conditions that all work undertaken pursuant to this authority shall be economically justified prior to construction, and local cooperation specified in 1936 Flood Control Act, as amended, shall be required. (See table 39-C for local flood projects in Walla Walla District.) (Note: This table does not include improvements in Portland and Seattle districts.) Local cooperation. Section 3 of the Flood Control Act approved June 22, 1936, as amended, applies to all the flood control projects. Operations and results during fiscal year. Costs were incurred only on John Day River area, Oregon, a fully authorized project which is reported in detail in an individual report. Condition at end of fiscal year. John Day River area, Oregon, is reported in detail in an individual project report. Boise Valley, Idaho (Ada County Unit) is the only other Columbia River Local Protection Project in a "work-in-progress" status. However, activity on this unit is suspended due to inability of sponsor to obtain rights-of-way. 6. COTTONWOOD CREEK DAM, IDAHO Location. On Cottonwood Creek at east city limits of Boise in Ada County, Idaho, in Section 2, Township 3 North, Range 2 East, Boise Meridian. Existing project. Plan of improvement provides for an earthfill dam with central impervious core, protected filter zone downstream from core and outer zones of random fill. A horizontal drainage blanket downstream from impervious core and a gravel blanket two feet thick will be used for protection of faces against erosion.

Operations and results during fiscalyear. New work: Work was continued under an agreement with NP Railway 1184 WALLA WALLA, WASH., DISTRICT Co. which provides that they design and reconstruct their Snake River Bridge No. 3. Alteration of bridge substructure was completed and work was begun on the superstructure. Attempts to reach an agreement with Union Pacific Railroad for modification of their Columbia River Bridge having failed, this part of the program was eliminated from McNary project and turned over to U.S. Coast Guard for continuing action under Truman- Hobbs Bridge Act. Code 710 Activity: Planning was continued for further development of recreation facilities in lake area. Additional land at Cold Springs site was acquired. Development was started at Two Rivers area, a site leased to Benton County, Washington. This work is being accomplished on a cost-sharing basis with the County. Operation and maintenance: Normal operation and maintenance of project continued. Approximately 5, 865,183 megawatt hours of electrical energy were delivered to Bonneville Power Administration, the marketing agency. A total of 1,958,817 tons of commodities passed through the navigation lock. Installation of equipment at McNary powerhouse for remote control of lower Snake River dams continued in conjunction with Lower Monumental and Little Goose Dams. A contract for $19,600 was completed for construction of project main entrance signs and recreation area entrance signs. Condition at end of fiscal year. Construction of existing project started May 1947 and is 99 percent complete (June 1970). Project was placed on a permanent operating basis and pool raised to normal operating elevation 340 in December 1953. Except for maintenance interruptions, all 14 power units have been in commercial operation since February 1957. Modification to a railroad bridge over Snake River remains to complete project. Northern Pacific Railway Co. is progressing with reconstruction of its Snake River Bridge No. 3, and the work is 35 percent completed. Modification involves funding by two projects-McNary Lock and Dam and Lower Monumental Lock and Dam. When Northern Pacific Snake River branch of the railway was condemned in conjunction with Lower Monumental Lock and Dam project, traffic was subsequently rerouted over Northern Pacific Snake River Bridge No. 3. In order to provide for increased traffic, load bearing capacity of bridge is being upgraded concurrently with navigation modification. 27. SNAKE RIVER DOWNSTREAM FROM JOHNSON BAR LANDING, OREG., WASH., AND IDAHO Location. On Snake River downstream from Johnson Bar Landing, river mile 231.

Previous projects. For details see Annual Reports, page 1981 for 1962, page 1991 for 1915, page 2246 for 1903, and page 1986 for 1906. Existing project. River and Harbor Act of 1945 (P.L. 14, 79th Cong., 1st sess.) authorized construction of such dams as are necessary and open channel improvements for purposes of providing slackwater navigation and irrigation between mouth of Snake River and Lewiston, Idaho. This authorization modifies previous authorizations only for that portion of improvement below Lewiston, Idaho. Acts of June 13, 1902, and August 30, 1935, as they pertain to open river improvement from Lewiston, Idaho, to Johnson Bar Landing are part of existing project. Improvements included in existing project and estimated Corps cost are Ice Harbor Lock and Dam, $160,500,000, including $2,800,000 for recreation facilities on completed project; Little Goose Lock and Dam, $152,000,000; Lower Granite Lock and Dam, $245,000,000; Lower Monumental Lock and Dam, $176,000,000; and open-river improvement, Lewiston to Johnson Bar Landing, $34,613. Total estimated cost is $733,534,613. Local cooperation. None required. Terminal facilities. On Snake River above Ice Harbor Dam are seven privately owned grain handling facilities which upon completion will all be equipped to load barges. Of these facilities four are in use and three are under construction. Also, there are four privately owned terminals below Ice Harbor Dam that provide for loading and unloading barges with petroleum products, chemicals, and Portland cement. In addition, there are four publicly owned marinas and 23 small boat launching ramps, all open to public use. Facilities are adequate until slackwater navigation is available and shipping volume increases following raising of pool behind Little Goose Dam. Operations and results during fiscal year. See individual reports for Lower Granite, Little Goose, Lower Monumental and Ice Harbor locks and dams. On Snake River from Lewiston, Idaho, to Johnson Bar Landing reconnaissance and condition surveys were conducted. Navigation aids were repaired and channel was renovated at Cottonwood Rapids. Condition at end of fiscal year. Costs of existing project were $483,844,962 for new work and $7,179,192 for maintenance, a total of $491,024,154 regular funds.

COLLECTION AND STUDY OF BASIC DATA During the fiscal year, flood hazard data for a number of locations in the District were collected and analyzed. Information was provided to several Federal agencies, to the states of Idaho, Oregon, and Washington, and to several private organizations. Flood plain information reports were completed for Umatilla River in vicinity of Pendleton, Oregon, and for Portneuf River and Tributaries near Pocatello, Idaho. Flood plain information report on Big Wood River at Ketchum, Idaho and vicinity was complete at end of fiscal year but will not be presented to local people until first quarter of fiscal year 1971. In addition, a flood hazard information special report was completed for a 6.8-mile reach of Paradise Creek at Pullman, Washington and vicinity. Total fiscal year costs were $109,066. (See table 39-K on completed flood plain studies.) 31. RESEARCH AND DEVELOPMENT Hydrologic investigations to improve runoff and streamflow forecasting procedures and flood frequency evaluations were continued from prior years. Studies were made of flood flows versus causes and of flood frequency statistics versus basin physical and hydrologic environment factors. Fiscal year cost of these studies was $5,715. 1186 TABLE 39-A See Section in Text Project Funding 2. Bear Creek, New Work: Kendrick, Idaho Approp. Cost 3.

ANCHORAGE HARBOR, ALASKA Location. Anchorage is in southcentral Alaska on southeast shore of Knik Arm and north of Turnagain Arm near junction with Cook Inlet. (See Coast and Geodetic Survey Charts 8553 and 8557.) Existing project. Provides for a deepwater harbor by dredging adjacent to existing and proposed municipal docks to a depth of 35 feet below mean lower low water and constructing two jetties of other protective works where required, along northerly and southerly ends. Tidal range between mean lower low water and mean higher high water is 28.1 feet and extreme range is 40.7 feet, based on preearthquake data. Large ice masses in winter months form into floe ice making it extremely hazardous for small boat navigation during that period. (See table 40-B for authorizing legislation.) Local cooperation. Local interests must provide easements, rights-of-way, and spoil-disposal areas; hold the United States free from damages; and construct wharf facilities adequate for handling of cargo. Terminal facilities. Four wharves capable of handling ocean going vessels and open for public use consist of two owned by the city, of which one is an oil handling and bunkering facility, and two are privately owned. Five additional wharves are privately owned and used for industrial purposes. A government owned wharf, damaged by the 1964 earthquake, has been reduced in size through removal and deterioration and is unuseable. Operations and results during the fiscal year. Regular funds, maintenance: Maintenance dredging to a depth of 37 feet, including advance maintenance, adjacent to the POL dock and city dry cargo wharf was accomplished July, August, and September 1969 by removal of 86,006 cubic yards of material at a cost of $396,502. Project sedimentation studies continued. Project condition survey was accomplished April 1970. Condition at end of fiscal year. Maintenance dredging was accomplished jointly by local interests and the United States Army to provide a depth of 35 feet alongside the City Dock and 32 feet at a distance of 50 * All cost and financial statements for projects are listed at the end of this chapter. All other tables are referenced in text and also appear at the end of this chapter. 1199 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 feet from the Ocean Dock in July 1961. Emergency dredging was performed off the face of the City Dock July and August 1965. The first phase of new work in the authorized project consisting of dredging the port area to a depth of 35 feet began October 1966 and was completed June 1967. Additional emergency dredging off the face of the City Dock was accomplished May and June 1969. 2. BETHEL SMALL BOAT HARBOR, ALASKA Location. The village of Bethel is 65 miles up river on the north bank of the Kuskokwim River which flows through southwestern Alaska. (See Coast and Geodetic Survey Chart 9302.) Existing project. Proposed project includes provision of a 7,700-foot long small boat harbor and entrance channel by deepening, widening and straightening of the upper 6,800 feet of Brown's Slough. (See table 40-B for authorizing legislation.) Local cooperation. Local interest will provide, maintain, and operate, without cost to the United States, as needed for transient and local operators, adequate public access roads, parking areas, and other needed public use shore facilities, open and available to all on equal terms. Provide, without cost to the United States, all necessary lands, easements, and rights-of-way required for construction and subsequent maintenance of the project, including suitable spoil disposal areas with any necessary retaining dikes, bulkheads, and embankments therefor. Hold and save the United States free from damages that may result from construction and maintenance of the project. Accomplish, without cost to the United States, alterations and relocations as required in sewer, water supply, drainage, and other utility facilities. Establish regulations concerning discharge of untreated sewage, garbage, and other pollutants in the waters of the anchorage by users thereof, which regulations shall be in accordance with applicable laws or regulations of Federal, State, and local authorities responsible for pollution prevention and control, and assure full responsibility for all project costs in excess of the Federal cost limitation of $500,000. Operations and results during fiscal year. Regular funds, new works: Preconstruction planning was initiated and is underway. Condition at end of fiscaly ear. Navigation improvement was adopted on 30 December 1969. Preliminary design work on plans and specifications are underway. 3. CORDOVA HARBOR, ALASKA Location. On Orca Inlet, a strait near eastern entrance to Prince William Sound, Alaska, about 150 air miles south-southeast of Anchorage, Alaska. (See Coast and Geodetic Survey Charts 8520, 8525, and 8551.) Existing project. A sheltered harbor for small boats about 8.26 acres in area with a depth of 10 feet at mean lower low water and 10.4 acres in area with a depth of 14 feet at mean lower low water protected by a north breakwater about 1,100 feet long and a south breakwater about 1,400 feet long. Tidal range between mean lower low water and mean higher high water is 12.4 feet, with an extreme range of 22 feet, based on preearthquake data. (See Table 40-B for authorizing legislation.) Local cooperation. None required. Terminal facilities. One privately owned wharf, capable of handling deep draft vessels, has oil-handling and bunkering facilities and is open for public use as passenger and general-cargo terminal. The municipal dock, with capability of handling deep draft vessels is open for use as passenger and general-cargo terminal. State of Alaska ferry terminal, a public loading dock, and Fish and Wildlife Service float are in the small boat harbor. Three additional wharves are privately owned and used for industrial purposes. Facilities are considered adequate for present commerce. Operations and results during the fiscal year. Regular funds, maintenance: Dredging of a shoal at the entrance to the small boat basin to a depth of 15 feet below mean lower low water was accomplished in April and May 1970. 5,700 cubic yards of material were removed at a cost of $34,320.00. Reestablishment of harbor lines is continuing. Project condition survey was accomplished during July and August 1969. Condition at end of fiscal year. The harbor with protecting breakwaters designed for future expansion within breakwater area and original construction was completed October 1938. Maintenance dredging was completed October 1962. Area uplift of 6.5 feet average resulting from the March 1964 earthquake necessitated harbor rehabilitation. Construction was initiated June 1964 for restoration phase and November 1964 for expansion phase. Project was essentially completed June 1965. Minor north breakwater repair contract was completed October 1965. Contract to construct an entrance breakwater was completed October 1966. 4. DILLINGHAM HARBOR, ALASKA Location. At head of Nushagak Bay, an arm of Bristol Bay on right bank of Nushagak River just below its confluence with Wood River, and about 470 miles northeasterly of Dutch Harbor, Alaska. (See Coast and Geodetic Survey Chart 9052.) Existing Project. A small boat basin 230,000 square feet in area with a depth of 2 feet above mean lower low water along Scandinavian Creek with entrance channel 1,100 feet long and a bottom width of 40 feet in Scandinavian Creek, and sheet-pile sill across the basin outlet with a top elevation of 7 feet above mean lower low water. During design stage the project was revised to include a rock sill with adjacent scour-protection blankets and the embankment was relocated to include a berm between the basin and embankment. Tidal range between mean lower low and mean higher high water is 19.8 feet. Extreme range is 27.5 feet. (See table 40-B for authorizing legislation.) Local cooperation. Fully complied with. 1200 ALASKA DISTRICT Terminal facilities. Three docks at the village of Dillingham, all privately owned, two are used for salmon-cannery operations and one as an oil-handling and bunkering terminal. Facilities are considered adequate for existing commerce. Approach and floats were installed in small boat basin in summer of 1963. Floats are removed before fall freezeup and replaced each spring to the extent permissable, governed by shoaling conditions. Operations and results during fiscal year. Regular funds, maintenance: Government plant and hired labor, 1 July through 25 October 1969 and 11 May through 30 June 1970, dredged 57,524 cubic yards of material from the basin area at a cost of $93,950. Project sedimentation study is continuing. Condition at end of fiscal year. Project was essentially completed in September 1961. The partially completed rock sill was damaged during the 1961 winter season closure and the basin silted in. Restoration of the rock sill and dredging of the basin commenced in May and was completed July 1962. A study of siltation was completed September 1966. An eight-inch cutterhead dredge purchased for annual maintenance of the basin was delivered June 1969 and dredging began 27 June 1969 and continued through October 1969 when work shutdown for winter. Annual maintenance dredging was reactivated May 1970. 5. EGEGIK RIVER, ALASKA Location. Egegik River, located on the Alaska Peninsula in southwestern Alaska, is the outlet of Becharof Lake and flows northwesterly from the lake for a distance of about 34 miles into Bristol Bay, 470 miles northeasterly from Dutch Harbor. (See wall map of Alaska by the Mineral Resources Branch of the U. S. Geological Survey.) Existing project. This provides for a channel 100 feet wide, 5 feet deep, and about 2,500 feet long through the rapids at the head of the river by the removal of obstructing boulders and the erection of suitable ranges to mark the channel. The flow of the river is so well regulated by the lake that the maximum range, except for tidal action at the mouth, is only 2 feet. The estimate of cost for new work, made in 1932, was $5, 000. (See table 40-B for authorizing legislation.) Terminal facilities. There are no terminal facilities. Operations and results during fiscal year. Regular funds, maintenance: Funds in the amount of $30,000 were appropriated for removal of additional boulders. Due to lack of response to the invitation for bids the work has been deferred until fiscal year 1971. Condition at end of fiscal year. The existing project was completed in 1941. 6. HOMER HARBOR, ALASKA Location. In Kachemak Bay, on Kenai Peninsula, 152 miles by water southwest of Anchorage and 15 miles northeast of Seldovia.

The Board comprises 7 senior engineer officers. Normally the Chairman is the Deputy Chief of Engineers. Five members are Division Engineers (rotative basis) from continental U.S. divisions. The seventh officer is assigned full time as Resident Member and directs the staff. Appointments are made by the Chief of Engineers for unspecified periods. The Board meets on call of the Chairman. Statutory duties of the Board as set forth in the act of June 13, 1902, and subsequent acts and amendments are: (a) to conduct an independent review of survey reports covering projects for river and harbor, flood control, and multiple-purpose improvements prepared by the Corps in response to an act of the Congress or a resolution of the House or Senate Public Works Committees, and to report its conclusions and recommendations thereon to the Chief of Engineers, who forwards the reports with his conclusions and recommendations to the Secretary of the Army for transmission to the Congress; (b) to conduct an independent review of special reports ordered by the Congress and report thereon in the same manner as for survey reports when directed by the Chief of Engineers; (c) to consider and approve general plans for major modification and reconstruction of any lock, canal, canalized river or other work for the use of benefit of navigation. The functions of the former Beach Erosion Board pertaining to review of reports concerning erosion of the shores of coastal and lake waters, and the protection of such shores, were transferred to the Board under section 3, Public Law 88-172. An additional statutory duty was assigned the Board under the terms of the Merchant Marine Act of June 5, 1920. Under this act, the Board, in cooperation with the Maritime Administration, collects, compiles, and publishes information on characteristics of U. S. ports. Physical characteristics of the ports are the responsibility of the Corps, and administrative characteristics are the responsibility of the Maritime Administration. In addition to its statutory duties, the following duties are the more significant among those assigned by the Chief of Engineers: review Corps policies and procedures as directed; review reports of other Federal agencies pertaining to water resources development; conduct investigations and studies of economics of ports and waterways; and conduct a year-long program of in-service training for planners at GS-12 and GS-13 levels in all aspects of Federal water resources development to assist in meeting the needs of the Corps for increased numbers of qualified personnel in this field. Also, the Resident Member is alternate for the Secretary of the Army on the Foreign-Trade Zones Board, first alternate for the Chief of Engineers on the National Capital Planning Commission, and ex-officio secretary of the American Section, Permanent International Association of Navigation Congresses, a quasi-official organization. (See separate section on PIANC). On June 30, 1970, the Board was composed of the following members: Maj. Gen. C. H. Dunn, Deputy Chief of Engineers, Chairman; Maj. Gen. Richard H. Free, Division Engineer, U. S. Army Engineer Division, South Atlantic; Maj. Gen. Charles M. Duke, Division Engineer, U. S. Army Engineer Division, North Atlantic; Maj. Gen. A. P. Rollins, Jr., Division Engineer, U. S. Army Engineer Division, Lower Mississippi Valley; Maj. Gen Willard Roper, Division Engineer, U. S. Army Engineer Division, Ohio River; Brig. Gen. Roy S. Kelley, Division Engineer, U. S. Army Engineer Division, North Pacific; and Col. Alvin D. Wilder, Resident Member. In addition to the foregoing, the following officers were also assigned for various periods during the year to membership on the Board: Maj. Gen. Robert G. MacDonnell, President, Mississippi River Commission, Vicksburg, Mississippi; * All cost and financial statements for projects are listed at the end of this chapter. All other tables are referenced in text and also appear at the end of this chapter. 1215 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Maj. Gen. Frederick J. Clarke, Deputy Chief of Engineers, Washington, D. C.; Maj. Gen. Thomas J. Hayes, III' Division Engineer, U. S. Army Engineer Division, South Atlantic; Brig. Gen. C. Craig Cannon, U. S. Army Engineer Division, Missouri River; Brig. Gen. William M. Glasgow, Jr., Division Engineer, U. S. Army Engineer Division, South Pacific; Brig. Gen. Robert M. Tarbox, Division Engineer, U. S. Army Engineer Division, North Central; Lieut. Gen. William F. Cassidy was named Chairman of the Board from November 1, 1969 to his retirement on May 31, 1970. A summary of investigations authorized by the Congress from establishment of the Board in 1902 to the end of fiscal year 1970, the number of authorizations completed, the number of authorizations remaining to be reported on, and the number of reports submitted under continuing authorizations are set forth in table 41-A under Board of Engineers for Rivers and Harbors. From 1902 through June 30, 1970, the Board took final action on 8,018 reports, recommending favorably on 3,557. By Public Law 85-500, Congress eliminated preliminary examinations. During fiscal year 1970, the Board held six meetings of 1 to 3 days' duration in Washington. Two public hearings were held, one on Snoqualmie River, North Bend, Washington, and the other on Sabine River, Longview, Texas. The Board considered 81 reports, acted favorably on 31, unfavorably on 25, deferred action on 15, and returned 7, reporting offices withdrew 3. The Board recommended construction of projects totaling $507,621,300 of which $449,177,800 was the estimated U. S. cost and $58,443, 500 the cost to local interests for work and cash contributions. Of the 25 unfavorable reports acted on by the Board, 1 involved construction costs estimated at $9,384,000 consisting of $9,364,000 Federal, and $20, 000 non-Federal. The remaining 24 reports contained no cost estimates as they dealt with improvements that were obviously unfavorable or no longer necessary. The Board's staff submitted reports or comments on reports as follows: 4 Department of Interior report reviews; 31 Report reviews on small projects (prepared under continuing authorities); 3 Special reports on civil works planning; 20 Report reviews (preliminary reviews with special purposes in mind); and 2 Miscellaneous reports (Mekong Delta report and Corps presentation to American Petroleum Institute). Studies prescribed by various River and Harbor Acts and Section 8, Merchant Marine Act of 1920, continued, and the results were published in the series of reports titled "Port Series" (See Table 41-B). 1216 TABLE 41-A BOARD OF ENGINEERS FOR RIVERS AND HARBORS BOARD OF ENGINEERS FOR RIVERS AND HARBORS Reports Submitted During Fiscal Year Authorities Authorities Authorities Authorities Authorities 1970 (Under Con- Received Received Completed Completed Remaining tinuing, Multiple Authority for Prior to During Prior to During to be and Special Investigation July 1, 1969 Fiscal Year July 1, 1969 Fiscal Year Reported on Authority) Flood Control and River and Harbor Acts, Exclusive of 1909 River and Harbor Act 5,180 0 4,851 20 309 River and Harbor Act of 1909- Continuing Authority for Major Modification 1 - - - 1 Congressional Resolutions Exclusive of Great Lakes Harbors 4,394 80 3,084 47 1,343 Congressional Resolutions Multiple Great Lakes Harbors Studies 2 0 2 0 - 0 PL 71-84-1 Authority for Multiple Hurricane Studies 1 - - - 1 1 River and Harbor Act, July 3, 1930 (PL 520-71), Cooperative Beach Erosion Studies 1 - - - 1 2 Total 9,579 80 7,937 67 1,655 3 TABLE 41-B PORTS SERIES PUBLICATIONS Published during the year: No. 15, The Port of Jacksonville, Florida No. 19, The Ports of Panama City and Pensacola, Florida; and Pascagoula, Mississippi No. 21, The Ports of Baton Rouge and Lake Charles, Louisiana No. 23, The Ports of Galveston and Texas City, Texas No. 25, The Port of Corpus Christi, Texas In progress at end of year: No. 11, The Port of Hampton Roads, Virginia No. 18, The Port of Mobile, Alabama No. 20, The Port of New Orleans, Louisiana No. 22, The Ports of Port Arthur, Beaumont, and Orange, Texas No. 24, The Port of Houston, Texas No. 26, The Ports of Freeport, Port Isabel, and Brownsville, Texas No. 50, The Ports of Honolulu, Nawiliwili, Port Allen, Kahului, Hilo, and Kawaihae, Hawaii 1217 MISSISSIPPI RIVER COMMISSION* The Mississippi River Commission, created by an act of Congress on June 28, 1879, consists of three officers of the Corps of Engineers, one from the Coast and Geodetic Survey, and three civilians, two of whom must be civil engineers.

Field operations of the Commission restricted to levee construction under section 6, 1928 Flood Control Act (local interests contributing one-third of costs and furnishing rights-of-way), are conducted within the following limits by two districts which report direct to the Commission on matters within their jurisdiction-St. Louis District: Mississippi River (sec. 6) levees from upper limits of Memphis District to Clemens Station, Mo. (1,254 miles AHP) on right bank and Hamburg Bay, Ill. (1,215 miles AHP) on left bank, and the Illinois River from its mouth to mile 120 at Havana, Ill. Rock Island District: Mississippi River (sec. 6) levees from upper limits of St. Louis District to Rock Island, Ill. (1,437 miles AHP). Work accomplished is shown on Table 42-N. MISSISSIPPI RIVER AND ALLUVIAL VALLEY BELOW CAPE GIRARDEAU, MO. Location and description. Mississippi River rises in Lake Itasca, Minn., and flows generally southerly for 2,340 miles through central portion of United States to empty into Gulf of Mexico about 115 miles below New Orleans. It is improved for barge navigation for about 1,832 miles to Minneapolis, Minn. The Mississippi River and its major tributaries, the Missouri, Ohio, St. Francis, White, Arkansas, Yazoo, and Red-Old Rivers, drain 1,245,000 square miles in all or part of 31 States between the Rocky and Appalachian Mountains and part of two Canadian Provinces. Below Cape Girardeau, Mo., 53 miles above Ohio River, river bottom lands widen abruptly into an alluvial valley of about 35,460 square miles which was originally subject to flood overflow. A major part of alluvial valley has been protected from floods by levees which confine floodflows within a flood plain having an average width of about 5 miles. (See map of alluvial valley of Mississippi River, scale 1:500,000.) Observations made by Mississippi River Commission to June 30, 1969, show approximate maximum and minimum discharges between 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 Mississippi River and about 660,000 and 11,000 cubic feet per second in Atchafalaya River. As 1927 floodflow was not confined between levees, maximum discharges recorded do not include entire flow of 1927 flood, maximum of record below White River. High water and flood stages usually occur in late winter or early spring, but great floods such as that of 1937 occurred as early as January. Low water stages generally prevail from August to December. Extreme ranges in stages recorded at representative gages are about 60 feet at Cairo, 55 feet at Memphis,. 58 feet at Red River Landing, and 23 feet at New Orleans (Carrollton). River is nontidal above Red River Landing where tidal amplitude rarely exceeds 0.1 foot during extreme low water. Previous projects. For details see page 1944, Annual Report for 1932, and page 1682, Annual Report for 1937. Existing project. For the Mississippi River and tributaries in alluvial valley between Head of Passes, La., and Cape Girardeau, Mo., provides for protection thereof from floods by means of levees, floodwalls, floodways, reservoirs (in Yazoo and St. Francis Basins), bank stabilization, and channel improvements in and along the river and its tributaries and outlets insofar as affected by backwater of Mississippi River, including levee work on main stem between Cape Girardeau and Rock Island. When completed, 23,621 square miles will be protected from the Mississippi River project flood. Project also provides for a 12- by 300- foot navigation channel between Baton Rouge, La., and Cairo, Ill.; for salinity control structures; and for channel realinement and improvement including bank stabilization and dikes to reduce flood heights, control natural tendency of river to lengthen by meandering, and protect levees from being destroyed by caving banks. Locations of major main stem Mississippi River improvements are shown in Table 42-A and those for off-main stem tributaries are shown in Table 42-B. Pertinent data on dams and reservoirs are shown in Table 42-C. Authorizing and Incorporating legislation are shown in Tables 42-D and 42-E. Summary of presently estimated Federal cost of authorized improvements is shown in Table 42-F. Construction of existing project began in 1928 and has continued throughout ensuing years. Based on the estimated cost of $2,831,763,000 (July 1, 1970 price levels) and actual expenditures through June 30, 1970 of $1,620,936,200, the entire project is about 57 percent complete. Recommended modifications. None. 1220 MISSISSIPPI RIVER COMMISSION Local cooperation. The Flood Control Act of 1928, as amended, applies. Such requirements have, in general, been complied with by local interests. Terminal facilities. See volume 1 of 2-volume Port Series No. 21, 1969, "Ports on the Gulf Coast of the United States," for Baton Rouge and Lake Charles, La.; Port Series No. 20, 1969, for New Orleans, La.; also folio of Flood Control and Navigation Maps of Mississippi River, Cairo, Ill., to the Gulf of Mexico (37th edition), 1969. Project cost. Total monetary authorizations, including the modifications to June 30, 1970, are $1,851,922,600. Total allotted for flood control, including maintenance charges through August 18, 1941, chargeable under authorizations to June 30, 1970, was $1,630,838,100. (See Table 42-S.). (See also Tables 42-R, 42-T, and 42- U for additional financial statements.) Operations and results during fiscal year. Commission activities: The 280th session was held, October 20-25, 1969, on board the U. S. MV Mississippi en route on the Mississippi River from Cape Girardeau, Mo., to Old River, La., on Old River to the Atchafalaya River, and on the Atchafalaya River to Morgan City, La. The 281st session was held, May 11-15, 1970, on board the U. S. MV Mississippi en route on the Mississippi River from Cairo, Ill., to New Orleans, La. On these river trips, major features of the project were inspected, including bank protection works, contraction works, levees, and general channel conditions, to the extent permitted by river stages. Public meetings were held, at which representatives of local governmental agencies, navigation, levee, commercial, and other interests presented problems pertaining to flood control and navigation. During the 280th session, some members of the Commission inspected the East Atchafalaya guide levee from Krotz Springs to Morgan City, La. The President, Mississippi River Commission, and his engineering assistants made periodic inspections of flood control, navigation, and related works under the existing project along the Mississippi River and tributaries in the alluvial valley from Cape Girardeau, Mo., to the Gulf of Mexico. District Engineers held flood-fight planning conferences with local interests. Three favorable reports, prepared under MR&T authority, were as follows: "Muddy Bayou (Eagle Lake), Louisiana and Mississippi" to provide construction of a water-control structure in Muddy Bayou to regulate flows in and out of Eagle Lake to minimize fishery losses, was forwarded to the Chief of Engineers February 2, 1970. This modification was approved as a feature of the Yazoo backwater project March 3, 1970. "Improvement of Rocky Bayou, Yazoo County, Mississippi" to provide improvement on 0.1 mile of channel clearing riverward of the Rocky Bayou drainage structure and 7.7 miles of channel enlargement upstream from the structure, was forwarded to the Chief of Engineers March 6, 1970. Modification approved as a feature of the Yazoo headwater project April 29, 1970. "Additional Drainage Facilities Upper Pointe Coupee Loop Area, Louisiana" to provide for enlargement of Bayou Latenache from the Pointe Coupee drainage structure to Alabama Bayou. New Orleans District's revised report was approved June 4, 1970 and copies furnished the Chief of Engineers June 5, 1970. Improvement will be a feature of the Atchafalaya Basin project. Alluvial valley mapping: Contoured quadrangles and general maps of the alluvial valley are available for departmental use and public distribution under prescribed regulations. Road-map-type information folders of principal portions of overall project were published along with papers on subject of flood control and navigation. Preparation and publication of quadrangle maps (scale 1:62,500) continued. The 1969 (37th) edition of the folio of flood control and navigation maps, scale 1:62,500, covering Mississippi River from Cairo, Ill., to Gulf of Mexico was compiled and printed. Some 6,893 flight-line miles of aerial photography (various scales) and 10 hours of oblique photography were flown along Mississippi River and tributaries and other areas in New Orleans, Vicksburg, and Memphis Districts. Work accomplished in the districts: New Orleans District-Series conversions of the Belle Isle, Morgan City, Napoleonville, New Orleans, and Spanish Fort quadrangles were printed. Work on the Bonnet Carre, Chef Menteur, Covington, Hahnville, Ponchatoula, Rigolets, St. Bernard, and Yscloskey quadrangles is nearing completion. Surveying, mapping, and scribing of hydrographic and topographic maps of Red River are now completed. The two folios of maps were printed by WES. Vicksburg District-Series conversion of U. S. Geological Survey 1:24,000 scale quadrangles to 1:62, 500 scale with addition of flood control features of the Swan Lake, Miss. and Humphrey, Ark. quadrangles were completed and printed. Marks and Pace, Miss. quadrangles are in progress. Memphis District-Four series conversions, Brownsville and Bells, Tenn., and Henrico and Indian Bay, Ark., quadrangles were completed and printed. Greenville and Poplar Bluff, Mo., DeWitt, Ark., and Trague, Tenn., were completed and are ready for printing. Augusta and De Valls Bluff, Ark., and Whiteville, Tenn., are ready for color proofs. Alamo, Humboldt, Middleton, and Whiteville, Tenn., and Clarendon and Gregory, Ark., and Charleston, Mo., are in progress. Surveys, gages, and observations: Routine hydrographic surveys, construction surveys, 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 districts. FLOODS: Memphis District -Mississippi River crest stage of 49.16 feet at Cairo gage and maximum discharge of 1, 168,000 cubic feet per second occurred on May 7, 1970, 1221 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 due to moderate to heavy rains that fell, during the period April 18-May 1, over the lower Missouri River and Ohio River Valley. Vicksburg District -Mississippi River crest stage of 36.79 feet on the Arkansas City gage on May 15 was the high est recorded since 1962. Crest stages at Arkansas City, Vicksburg, and Natchez were 7.2, 1.0, and 2.2 feet below flood stage, respectively. Crest stage on the Ouachita River occurred at Arkadelphia on March 4 at 19.0 feet, 2 feet above flood stage, and at Camden on March 8, at 33.0 feet, 7 feet above flood stage. Flood control works reduced crest stages about 5 feet at Arkadelphia and about 3 feet at Camden. Stages on the Coldwater-Tallahatchie-Yazoo kivers were moderately high, December through May 1970. The crest stage on the Tallahatchie River at Swan Lake occurred in March and was 0.3 feet above flood stage. Operation of flood control works effected reductions averaging about 5 feet on the Coldwater and Tallahatchie Rivers, about 7 feet at Greenwood, and 4 feet at Yazoo City. Crest stages on the Big Black River were about 8 feet above bankfull. New Orleans District -No flood stages were recorded in the lower Mississippi and Red River Basins. Investigations and reports: Surveys and reports prescribed under existing project, and called for by congressional or departmental directives, were made as required. Memphis District expended $33,173 on one navigation study, $318,585 on six flood control studies, and $39,999 on collection and study of basic data. Vicksburg District expended $54,477 on one navigation study, $205,287 on four flood control studies, and $70,725 on collection and study of basic data. New Orleans District expended $65,497 on three flood control studies and $20,272 on one navigation study. Surveys were made and gages operated and maintained. In addition, $577,460 was expended on the West Texas and Eastern New Mexico Water Import Study to determine the advisability of improvements for exporting, by the most feasible means, surplus water, if any, in the Mississippi River system to water-deficient areas. This investigation is being made in cooperation with the Bureau of Reclamation in its current reconnaissance studies of measures for importing water into west Texas and eastern New Mexico. The Southwestern Division, Corps of Engineers, will make studies for that portion of the area within its boundaries. MISSISSIPPI RIVER-LEVEES Operations and results during fiscal year. Enlargement of dikes and restoration of eroded portions of existing levees; enlargement of existing levees to approved grade and section, 0.8 mile in New Orleans District, and 1.3 miles in Memphis District; construction of levee berms, 3.8 miles in Vicksburg District, and 1.7 miles in Memphis District; surfacing material placed on 1.3 miles of levee roads in Memphis District; and construction of 0.8 mile of new levee wavewash protection along the lower Mississippi River below Baton Rouge. Restoration of damaged wavewash and foreshore protection was accomplished as required. For further details see Tables 42-K, 42-L, and 42-M. Condition at end of fiscal year. There are 1,597 miles of levee now authorized for the Mississippi River below Cape Girardeau, of which 1,565 are in place with 1,390 built to approved grade and section. (Above figures include 72 miles on completed separable features.) The Main Stem Levee System consisting of 2,192 miles, of which 1,876 have been completed, includes additional levees and structures along the south bank of Arkansas River (85.4 miles); along the south bank of Red River (59.8 miles, with 51.6 completed); and 449.2 miles in the Atchafalaya River Basin, with 349.1 essentially completed (216.1 to grade and section and 133.0 to grade only). Graveled or hard-surfaced roads have been constructed on 970 miles of these levees. (Tables 42-K, 42-L, and 42-M.) Below Baton Rouge, in New Orleans District, about 137 miles of levee are protected against river wavewash by timber structures or leveeslope pavement. In order to insure adequacy of main stem levees, including those on south banks of Arkansas and Red Rivers, additional levee construction is recommended to provide a standard 3-foot freeboard, adequate levee cross section, construction of berms for levee stabilization and seepage control, levee wavewash protection where necessary, drainage structures, and roadways for proper inspection and maintenance. Status of levees authorized under provisions of section 6, 1928 act is summarized in Table 42-N. MISSISSIPPI RIVER-CHANNEL IMPROVEMENTS Operations and results during fiscal year. Engineering studies: Continued a research program for development of materials and more effective and economical procedures for placing and stabilizing Mississippi River in a suitable alinement. Bank revetment and dikes: Construction of 13.0 miles of new bank revetment and 6.0 miles of reinforcement of existing revetment was completed by Government plant and hired labor, and construction of 11.7 miles of new dikes was completed by contract. Further data concerning this work are shown by districts in Tables 42-H, 42-I, and 42-J. Dredging: Work included dredging 48,609,000 cubic yards for channel and harbor maintenance and channel construction and revetment. Minimum channel depth of 9 feet was maintained. Dredging shown in Table 42-G was done with the following plant: New Orleans District, one contract cutterhead dredge and one Government-owned dustpan dredge (on loan); Vicksburg District, one Government-owned dustpan dredge, one Government-owned dustpan dredge (on loan), and one leased cutterhead dredge; and Memphis District, three Government-owned dustpan dredges and one leased cutterhead dredge. (See also Tables 42- O, 42-P, and 42-Q). Other work performed in interest of navigation, supplementing maintenance dredging on Mississippi 1222 MISSISSIPPI RIVER COMMISSION River between Cairo, Ill., and Baton Rouge, La., included removal of snags, wrecks and obstructions; issuance of bulletins by the Vicksburg District providing information on available high-water velocities at selected locations; maintaining bulletin boards showing daily gage readings at regular MRC gages; and contact pilot service furnishing navigation with latest information and advice on channel conditions and obtaining their views as to needs of navigation interests. Cost of this work is given in Table 42-R. Condition at end offiscalyear. In carrying out authorized channel improvement program between Baton Rouge and Cairo, 16 cutoffs were developed between 1933 and 1942. These, combined with chute channel development and alinement improvements, decreased channel length between these cities by about 180 miles. Effect of this channel shortening, in increasing its floodcarrying capacity, is stated on page 1811, Annual Report for 1943. Much progress has been made in advancing overall channel stabilization program, involving construction of bank revetment, dikes, and improvement dredging, to prevent river from regaining its former length due to its natural tendency to meander. There are now in place 608 miles of operative bank revetment and 114 miles of dikes on Mississippi and lower Ohio Rivers as listed on Tables 42-H, 42-I, and 42-J. A navigation channel 9 by 300 feet is maintained by dredging as required during low-water season. Due to growing effectiveness of channel improvement program, average maintenance dredging requirements are steadily being reduced, and an increase in navigable depth is being obtained. A longrange plan has been developed and recommended to bring about desired program of channel improvement between Cairo and Head of Passes including additional bank revetment, dredging, contraction works, and foreshore protection. Approximately 93 miles of foreshore protection have been constructed along the lower Mississippi River. NEW ORLEANS DISTRICT ATCHAFALAYA BASIN, LA. Operations and results during fiscal year. New work by hired labor: Real estate activities and planning for construction were continued. Bank stabilization consisted of placing 1.7 miles of articulated concrete mattress between miles 13 and 18 at McCrea, Woodside, Provosty, and Crooked Bayou, La., on the Atchafalaya River, and reinforcement of 0.1 mile of existing revetment at Provosty, La. New work by contract: Construction of floodside and landside berms and levee enlargement continued on the east and west protection levees. In completing contracts initiated in previous fiscal years, approximately 826,957 cubic yards of levee and berm embankment were placed in the east protection levee over a distance of 5.9 miles and 328,789 cubic yards in the west protection levee for 2.9 miles. Three contracts for enlargement of the east protection levee were initiated, involving placement of 7,421 cubic yards this fiscal year for a distance of 0.4 mile. Maintenance by hired labor: Bayou Boeuf, Berwick, and Bayou Sorrel locks, Morganza control structure, and the numerous drainage and flood control structures were operated and maintained as required throughout the fiscal year. Clearing, dressing and seeding of hydraulic berms on the east and west protection levees was accomplished intermittently during the year. Maintenance of existing revetments was performed during the fiscal year. Approximately 18 miles of clearing and snagging and removal of shoal in west protection levee borrow pits were accomplished between August 18, 1969 and March 2, 1970. Maintenance by contract: Construction of a setback at Toles in the East Atchafalaya River levee, mile 34.5, was initiated on March 6, 1970, and is 23 percent complete. One slide at Toles, East Atchafalaya River levee, Item A-34.0-L, two in the east protection levee, Item E-46.0, and one in the west protection levee, Item W-99.0, were repaired during the fiscal year. Approximately 96,540 cubic yards of embankment were placed in the setback and 98,835 cubic yards in the slide repairs. Dredging at Three Rivers by the dredge Holland consisted of removal of 53,507 cubic yards of shoal between July 25 and 30, 1969. The dredge M. H. Bean removed 13,336 cubic yards between March 16 and 18, 1970 in excavating a channel on Item E-46.0 to restore the drainage capacity of the landside borrow pit. Condition at end offiscalyear. Construction was initiated August 7, 1929 with the commencement of the west protection levee from Bordelonville to Hamburg. The project is 45 percent complete, based on the current estimated cost of $381,000,000 which includes funds for Upper Pointe Coupee Loop Area. The 449.2 miles of levees and floodwalls authorized for the system have been constructed with 349.1 miles built to grade and section. See Table 42-K for status of levees. Major components completed include Morganza and West Atchafalaya Floodways including railroads and highway crossing, (except permanent paving of U. S. Highway 190 crossing the West Floodway), Wax Lake Outlet, Charenton drainage canal, three navigation locks, ten pumping plants, Atchafalaya River navigation channel, and numerous flood control and drainage structures. Major items remaining to be completed include completion of levees to grade and section, channel improvement by dredging to reduce flowline, and bank stabilization. The channel has been enlarged to 60,000 square feet from mile 54.5 to 96.2, and to 40,000 square feet from mile 96.2 to 112.3. Enlargement to 100,000 square feet from mile 54.5 to 112.3 remains to be done. Drainage improvements in Upper Pointe Coupee Loop Area have not been initiated. Approximately 9.8 miles of bank stabilization has been placed as shown in Table 42-H. 1223 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 BATON ROUGE HARBOR (DEVILS SWAMP), LA. Operations and results during fiscal year. Maintenance by hired labor consisted of dredging to remove shoal by Government-owned dredge Jadwin on loan from Vicksburg District.

Army Coastal Engineering Research Center (CERC) was established under authority of Public Law, 172, 88th Congress, which abolished the former Beach Erosion Board (organized under authority of sec.2, 1930 River and Harbor Act, as amended (33 USC 426), and directed that its functions other than the review of reports of investigations made concerning erosion and protection of shores of coastal and lake waters, be vested with the Coastal Engineering Research Center. The report review function was transferred to the Board of Engineers for Rivers and Harbors, putting reports on beach erosion control and shore protection studies under the same review procedures as reports in other phases of the water resources study program of the Corps. The authorizing act also provided that the functions of the Coastal Engineering Research Center be conducted with the guidance and advice of a Coastal Engineering Research Board, to be constituted by the Chief of Engineers in the same manner as the former Beach Erosion Board. During Fiscal Year 1970 the following served as members of the Coastal Engineering Research Board: Major General Francis P. Koisch, U. S. Army, Director of Civil Works, Office Chief of Engineers, President; Major General Charles M. Duke, U. S. Army, Division Engineer, North Atlantic Division; Major General Thomas J. Hayes, III, U. S. Army, Division Engineer, South Atlantic Division; Brigadier General William M. Glasgow, Jr., U. S. Army, Division Engineer, South Pacific Division; Brigadier General William W. Watkin, Jr., Division Engineer, North Central Division; Dean Morrough P. O'Brien, Dean Emeritus of College of Engineering, University of California; Dr. Arthur T. Ippen, Professor of Hydraulics, Massachusetts Institute of Technology, and Dr. Robert G. Dean, Chairman of the Department of Coastal and Oceanographic Engineering, University of Florida. Lieutenant Colonel Edward M. Willis was Executive Secretary to the Board and Director of the Center. The Coastal Engineering Research Center is the principal research and development facility of the Corps in the field of coastal engineering. The mission of the Center is to: (a.) Conceive, plan and conduct research and development in the field of coastal engineering, in order to provide a better understanding of coastal processes. winds, waves, tides, currents, and materials as they apply to navigation, recreation, flood and storm protection, shore and beach erosion control, shore structures, and offshore islands and structures; (b.) Conceive, plan and conduct research on the effects of the coastal activities of the Corps of Engineers on the ecology of the coastal zone; (c.) Collect and publish information and data concerning coastal phenomena and reasearch projects which are useful to the Corps of Engineers and to the public; (d.) Assist in the planning and design of coastal works, including determination of probable effects of such works on adjacent shores, establishment of hurricane protection criteria; and evaluation of the stability, durability and effectiveness of proposed coastal navigation improvements and other coastal works; (e.) Assist in the review, for technical adequacy, of studies, plans, and specifications for beach erosion control and other coastal engineering works; (f.) Provide specialized consulting services to other elements of the Corps of Engineers and, as directed, to other Federal agencies; and (g.) Provide specialized training in coastal engineering to other public agencies. Operations and results during fiscal year. The staff of Coastal Engineering Research Center reviewed 29 reports for technical adequacy; of which 8 concerned navigation projects, 19 concerned beach erosion control projects, one concerned combined beach erosion control-navigation project, and one concerned a combined beach erosion control-hurricane project. In keeping with the responsibility for publishing information and data concerning coastal phenomena, 11 technical reports by staff members were published by CERC or in other technical journals during the year and 7 others are currently in press. Four abstracts were published in technical journals. Three Technical Memorandums were issued by Coastal Engineering Research Center and 2 are in preparation to go to press. Four technical manuscripts were published in the "Miscellaneous Papers" series. Eighteen additional reports are in preparation. The staff worked on 10 major research or engineering projects for various agencies and prepared 5 reports thereon. A number of lesser studies were made and reported on. A training course in coastal engineering was given to a group of trainees from the Board of Engineers for Rivers and Harbors, and lectures were given by staff members to universities and to technical and non-technical groups. Members of the staff part participated in a number of committees of various technical societies. Research to supplement staff activities was carried out at 19 universities under 27 contracts, and with 10 institutions and commercial concerns; funds were also provided to the Waterways Experiment Station to assist in the construction of the generalized tidal inlet model basins and to continue work on mathematical modelling of harbor surging and on the study of underwater soil 1263 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 mechanics. At the end of the year work and studies by the staff were in progress on: the characteristics of ocean waves as determined by actual measurement at a number of field locations; the characteristics of coastal inlets; the analysis of wave spectra; the sources of sand for use as beach fill; the durability of various pile coatings in the surf zone; the relation of littoral drift to incident waves; the techniques for measuring littoral drift rates; embankment stability under wave action; the effectiveness of vegetation for dune stabilization; coastal problems peculiar to the Alaskan environment; the geomorphology of Atlantic coastal zone; the ecological effects of offshore dredging; the correlation of wave climate and beach deformation; the revision and updating of Technical Report No. 4, Shore Protection and Planning; the use of the middle ground shoal area as a deposition trap in sand bypassing; and the evaluation of completed coastal works. Research work at the Coastal Engineering Research Center, or being done at other institutions for the Center, was financed primarily by Coastal Engineering Research and Development Funds, General Expense Funds and Engineering Studies Funds. For FY 1970 appropriated and allotted funds in these three categories amounted to $3,100,000, $245,000, and $75,000 respectively. Reimbursable work done for others provided another $89,000 for in house use. 1264 CALIFORNIA DEBRIS COMMISSION* This Commission, consisting of three Corps officers appointed by the President with the consent of the Senate, created by act of 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 drainage area of Sacramento and San Joaquin Rivers, comprising great central valley of California and extending from crest of Sierra Nevada on the east to that of Coast Range on the west, and from Mount Shasta and Pitt River Basin on the north to Tehachapi Mountains on the south. These rivers empty into head of Suisun Bay ultimately discharging into Pacific Ocean through connecting bays and straits and the Golden Gate. Duties of the Commission comprise regulation of hydraulic mining in drainage area of Sacramento and San Joaquin Rivers, Calif., so that debris will not be carried into navigable waters or otherwise cause damage; jurisdiction over construction and control of water storage facilities for domestic, irrigation, and power development purposes; and direction of improvements for control of floods on Sacramento River.

Operations largely limited to territory between Mount Lassen on the north and Yosemite Valley on the south, on western watershed of Sierra Nevada. (See Geological Survey sheets for the area, 25 in number.) Existing project. Provides for regulating hydraulic mining operations, planning improvement of conditions upon Sacramento and San Joaquin Rivers and their tributaries affected by such operations, and preparation of plans to enable hydraulic mining to be resumed in their drainage areas. In addition, the Secretary of Army is authorized to enter into contracts to supply storage for water and use of outlet facilities from debris-storage reservoirs for domestic and irrigation purposes and power development, upon such conditions of delivery, use, and payment as he may approve. Applications of prospective miners are fully investigated by California Debris Commission and permits to operate are issued to those who provide satisfactory debris-restraining basins by construction of suitable dams where necessary or agree to make payment for storage in Government-constructed, debris-restraining reservoirs constructed under act of June 19, 1934, as set forth below. For location and description of Government-constructed, debris-restraining reservoirs for general hydraulic mining see Improvement 2. (See table 44-B for authorizing legislation.) Local cooperation. Mineowners must bear all expenses incurred in complying with orders of the Commission for regulation of mining and restraint of debris. Operations and results during fiscal year. Inspected Hydraulic mines to determine compliances of mineowners with requirements of license issued. Administrative work overlaps that of improvements 2, 3, and 4, hereunder, and that of Sacramento District. Condition at end of fiscal year. The Commission received 1,292 applications for hydraulic mining licenses; 3 mines are licensed, none of which use storage behind * All cost and financial statements for projects are listed at the end of this chapter.

Work remaining is, in general, continuation of above or similar operations. 2. SACRAMENTO RIVER AND TRIBUTARIES, CALIFORNIA (DEBRIS CONTROL) Location. Project reservoirs are to be constructed in watersheds of Yuba, Bear, and American Rivers, Calif. (See Geological Survey sheets for basin areas, seven in number.) Existing project. Designed to permit resumption of hydraulic mining on a substantial scale and provides for construction of reservoirs for purpose of retaining mining debris. North Fork Reservoir is on North Fork of American River about 5 miles northeast of city of Auburn and 40 miles northeast of Sacramento. Dam is 155 feet high, 620 feet long, and reservoir has debris" storage capacity of 26 million cubic yards. Harry L. Englebright Reservoir is on Yuba River about 20 miles northeast of city of Marysville. Dam is 280 feet high, 1, 142 feet long, and reservoir has a debris storage capacity of 118 million cubic yards. Completed reservoirs are also utilized for recreation purposes; initial facilities were provided in fiscal year 1959. Recreation areas at Harry L. Englebright Reservoir are maintained by the Corps. Recreation areas at North Fork Reservoir are maintained and operated by Auburn Recreation Park and Parkway District. Total Federal cost of new work for construction of these reservoirs was $4,646,872, including $40,000 for recreation facilities. Cost of recreation areas at North Fork Dam was $57,500. It is estimated (July 1970) that improvements to recreation areas will cost $1,173,000 for Harry L. Englebright Dam. Reservoir project sites on Middle Fork of American River and on Bear River are considered inactive and excluded from foregoing cost estimate. Estimated cost of this portion is $1,820, 000 (1935). Existing project was adopted by River and Harbor Act of 1935 (Rivers and Harbors Committee Doc. 50, 74th Cong., 1st sess.). For latest published map, see project document. Act of November 6, 1945, provided that dam constructed at Upper Narrows site on Yuba Rivdr, Calif., should thereafter be Harry L. Englebright Dam. Local cooperation. Satisfactory assurances were furnished the Secretary of the Army for repayment of capital cost of reservoir from taxes on material hydraulically mined, under licenses, and impounded in these reservoirs. These funds are paid to Director of Internal Revenue then credited by Treasurer of the United States to Hydraulic Mining in California Debris fund. Improvements made to facilities at North Fork Dam and Reservoir by Auburn Recreation Park and Parkway District under a lease agreement with the Secretary of the Army and Auburn Boat Clubs (concessionaire) at an estimated cost of $46,000 since September 1953. Licenses. Under provisions of Contract No. W-1105- eng-2998 with Pacific Gas and Electric Co., payment is to be made to the Federal Government of $18,000 per year for the first 30 years (December 29, 1942-1972) and $48,000 per year between December 29, 1972, and December 29, 1992, in return for use of head at Englebright Dam and generation of hydroelectric power. Total payment through June 30, 1970, amounts to $486,100; these funds are paid to California Debris Commission and deposited for credit by Director of Internal Revenue to "Debris Fund." Operations and results during fiscal year. New work: Englebright Reservoir, Code 710 funds-Engineering continued. Maintenance: Maintenance and operation activities continued at North Fork Dam at a cost of $30, 112, including recreation facilities ($7,726); and at Harry L. Englebright Dam at a cost of $57,868, including recreation facilities ($23,392), and excluding an addition to operators quarters at Harry L. Englebright Dam accomplished by contract, $14,444. Condition at end of fiscalyear. Construction of dams was initiated in 1937; North Fork Dam and Reservoir was completed and in use at end of fiscal year 1939; and Harry L. Englebright Dam and Reservoir was completed in January 1941. The two debris-control structures are in good condition. Public use of these reservoir recreation areas greatly overtaxes present capacities. 3. TREATMENT OF YUBA RIVER DEBRIS SITUATION-RESTRAINING BARRIERS, CALIFORNIA Location. Works are on Yuba River between Marysville and where the river emerges from the foothills, near Hammonton, some 10 miles easterly from Marysville, or about 9 miles below the Narrows. (See Geological Survey Topographic map of Sacramento Valley, Calif.) Existing project. Provides for storage of mining debris within riverbed of Yuba River, a nonnavigable stream, to keep such debris from passing into Feather and Sacramento Rivers to detriment of navigation therein. Improvement consists of a debris barrier, a 40-foot wide reinforced concrete stepped slab with upstream and downstream cutoff walls; training walls 85,100 feet long which provide a 600-foot wide channel above and a 500-foot wide channel b elow dam; dikes across overflow channels; and protective works downstream to maintain Yuba River in its confined channel to its junction with Feather River at Marysville. Total cost of new work was $723,259, of which $361,482 was U.S. funds and $361,777 required contributed funds by State of California. (For details of project in its original form, see Annual Report, 1917, p. 1810.) In February 1963, center section of dam failed and major rehabilitation of structure was completed in December 1964. Total cost for required rehabilitation was $1,660, 000, of which $830,000 was Federal cost and $830,000 required contribution by State of California toward rehabilitation cost. During the December 24, 1964, 1266 CALIFORNIA DEBRIS COMMISSION floodflows on the Yuba River, the rehabilitated Daguerre Point Dam sustained considerable damage. (See 1965 Annual Report, p. 1647 "Operations and results during fiscal year.") The reconstructed portion of the dam completed earlier in December 1964 was undamaged by the flood. Permanent repair of Daguerre Point Dam abutment and fish facilities was completed in October 1965 at a cost of $447,808 with Federal and required State contributed funds on a matching basis. Existing project was adopted in a rather indefinite form by River and Harbor Act of 1896 and in its more definite form by River and Harbor Act of 1902 (H. Doc. 431, 56th Cong., 1st sess.). (For latest published map, see Geological Survey topographic map of Sacramento Valley, Calif.) Local cooperation. Fully complied with for new work and major rehabilitation work. Total first cost to local interests for new work was $361,777, all of which was required contribution by State of California. In addition, training walls were built on each bank below Daguerre Point for 11,250 feet and just above Daguerre Point, on the south bank, for 11,000 linear feet by two gold-dredging companies in connection with their dredging operations. It was estimated (1902) that it would have cost the United States $450,000 to build these training walls. Flood channels were also built by gold-dredging companies within the confines of the project works. It was estimated (1926) that cost of equally effective works to restrain debris movement would have been more than $776,000 to the United States. Total costs to local interests for initial and permanent major rehabilitation works were $830,000 and $223,904, respectively, all of which was required contribution by State of California. State of California must contribute annually an amount equal to the Federal allotment for maintenance. Operations and results during fiscal year. Maintenance: Operations included condition and operation studies, and preparation of plans and specifications, by hired labor. Bank restoration and stone protection was accomplished along right and left banks Yuba River, various locations upstream from Marysville, at a contract cost of $33,127. In addition, repair of Daguerre Dam was accomplished at a contract cost of $14,840. Condition at end of fiscal year. Construction of project works was initiated in November 1902. Construction of Daguerre Point Dam was completed in May 1906; diversion of river over dam was completed in 1910; training walls and dikes were completed in 1935. About 140 million cubic yards of debris are held in lower 7 miles of Yuba River between Marysville and downstream end of training walls. About 20 million cubic yards are confined in river channel by Daguerre Point Dam. Additional millions of yards of loose material are in mine tailing fields adjacent to project training walls in upper 7-mile reach of project. Initial rehabilitation of Daguerre Point Dam begun in July 1963 was completed in December 1964. Contract for permanent rehabilitation of structure was initiated in July and completed in October 1965. FLOOD CONTROL 4. SACRAMENTO RIVER, CALIF. Location. Works covered by this improvement are on Sacramento River and tributaries in north-central California from Collinsville to Ord Bend, a distance of 184 miles. Previous project. For details see page 1815 of Annual Report for 1917, page 1995 of Annual Report for 1938, and page 2262 of Annual Report for 1907. Existing project. Sacramento River flood control project is a comprehensive plan of flood control for Sacramento River and lower reaches of its principal tributaries. Improvement extends along Sacramento River from Ord Bend in Glenn County, Calif., 184 miles downstream to its mouth at Collinsville at upper end of Suisun Bay, and comprises a system of levees, overflow weirs, drainage pumping plants, and flood bypass channels or floodways designed to carry surplus floodwaters without inundation of valley lands. About 980 miles of levee construction with an average height of 15 feet, and 98 miles of bank protection are involved in project. For further details, see Annual Report for 1962, page 2115. (See table 44-B for authorizing legislation.) Approved estimated (July 1970) cost for existing project (exclusive of above supplemental levee improvements), including new work and maintenance, is $163,640,000 of which $68,640,000 is Federal cost and $95 million non-Federal ($90,050,562 for lands and damages and relocations and $4,949,438 required contributed funds for levee construction, bank protection works, and levee setbacks). Of this amount $4, 939,752 was for new work and $9,686 for maintenance. In addition to project requirements, local interests constructed several pumping plants for drainage of agricultural and urban land protected by project levees. Also, some channel clearing work was accomplished by State of California and other local interests to supplement project levee construction. Dredging below Cache Slough and reconstruction of Cache Creek settling basin weir are considered deferred and excluded from foregoing cost estimate. Estimated cost (July 1962) of these project units is $2, 560,000 and $520,000, respectively, a total of $3,080, 000, plus U.S. costs, for construction. Operation and maintenance of completed project will be responsibility of local interests; as units of project are completed, they are transferred to agencies of State of California for operation and maintenance. Existing project was adopted by 1917 Flood Control Act (H. Doc. 81, 62d Cong., 1st sess., as modified by Rivers and Harbors Committee Doc. 5, 63d Cong., 1st sess.), 1928 Flood Control Act (S. Doc. 23, 69th Cong., 1st sess.), River and Harbor Act of 1937 (S. Committee print 75th 1267 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Cong., 1st sess.), and 1941 Flood Control Act (H. Doc. 205, 77th Cong., 1st sess.). Local cooperation. Local interests have fully complied with requirements for all work completed or under contract, and indicated they will be able to fulfill requirements for remaining work as scheduled. Local interests costs from required contributed funds for project work total $4,949,438 for levee construction, bank-protection works, and levee setbacks, of which $4, 939,752 was for new work and $9,686 for maintenance. Operations and results during fiscal year. Regular funds: Engineering continued and miscellaneous minor work in connection with levee construction was accomplished by hired labor. Project prevented an estimated $100,000 in damages from the January 1970 flood. Condition at end of fiscal year. Construction of existing project began in fiscal year 1918 and is about 99 percent complete. Channel improvement to date has produced a channel with a capacity of 579,000 cubic feet per second in Sacramento River below Cache Slough. In addition, discharges up to 21,000 cubic feet per second can be diverted from Sacramento River through Georgiana Slough. Completed major project items include about 977 miles of levees; five weirs with a combined discharge capacity of 602,000 cubic feet per second; two cutoff channels; two sets of outfall gates; channel improvement and clearing in Sacramento River, Butte Creek, Putah Creek, and Sutter and Tisdale Bypasses; construction of two main bypasses or floodways and secondary bypasses at Tisdale and Sacramento weirs and at Wadsworth Canal; construction of Knights Landing ridge cut and of Cache Creek settling basin; installation of gaging stations; and enlargement of Sacramento River below Cache Slough. Cutoffs at Collins Eddy and between Wild Irishman and Kinneys Bends were made in 1918 and 1919, respectively. Sacramento weir was completed in 1917, Fremont weir in 1924, Tisdale and Moulton weirs in 1932, and Colusa weir in 1933. Outfall gates at Knights Landing were constructed in 1930 and at mouth of Butte Slough in 1936. Pumping plants on Sutter Bypass were completed in 1944. Work items with reference to clearing, snagging, rectification of channels, and bank protection on Sacramento River and tributaries in Tehama County and from Red Bluff southerly, provided for by 1941 Flood Control Act were accomplished in fiscal years 1947, 1948, 1949, and 1951. Work remaining comprises completion of levee stage construction, Yolo Bypass and Cache Slough. (See table 44-C for total cost of existing project to June 30, 1970.)

The Chief of Engineers, by letter dated June 18, 1929, to the President of the Mississippi River Commission, directed establishment of an hydraulic laboratory in the alluvial valley of the Mississippi. This institution is the Waterways Experiment Station, with installations at Vicksburg and Jackson, Miss. It was initially established in 1929, under jurisdiction of the President, Mississippi River Commission. By General Order 9, Office, Chief of Engineers, July 29, 1949, the station was transferred to the direct jurisdiction of the Chief of Engineers, effective August 10, 1949. Colonel Ernest D. Peixotto, Corps of Engineers, is director. The organization is the principal field agency of the Corps for the conduct of scientific and engineering research, development, and investigational activities in technical fields of hydraulics, ground mobility, flexible pavements, soils other than those phases involving seasonal frost and permafrost, nuclear and conventional weapons effects on structures, terrain and waterways, and concrete other than those phases directly relating to design and construction of rigid pavements. On a reimbursable basis, Waterways Experiment Station performs experimental studies and applied research, and provides consulting services pertaining to problems encountered throughout the Corps as are within its broad capabilities in its assigned fields. Such services include model and prototype studies, engineering and analytical design studies including blast and shock effects, laboratory research concerning portland cement and bituminous concrete mixture proportioning, laboratory testing, and field investigations. Field investigation services include planning, accomplishment, and analysis of: comprehensive exploration of soil and rock formations; comprehensive examination and inspection of portland- cement concrete structures in service, including use of nondestructive testing procedures; instrumentation systems to measure water velocities and directions and to determine pressures, deflections, and strains in engineering structures; telemetry systems, principally for hydrologic data; and field inspection services, including establishment of control laboratories and training field personnel. Subject to approval by the Chief of Engineers, studies can also be undertaken for other agencies. The Waterways Experiment Station also operates for the Corps a central agency for analysis and dissemination of technical information, particularly in, but not necessarily limited to, fields covered by Hydraulics, Soils, and Concrete Divisions. In connection with this fact-disseminating service, the station maintains an extensive scientific and engineering reference library and issues publications of general interest, which can aid materially in eliminating dduplication of effort throughout the Corps in the conduct of experimental studies. During Fiscal Year 1970, 160 reports of individual studies conducted at the Waterways Experiment Station, 7 translations, 20 contract reports, and 28 miscellaneous publications for the Waterways Experiment Station and other offices were distributed to Corps offices and interested outside agencies. In addition, editing and printing units completed about 2,650 miscellaneous assignments for the Waterways Experiment Station and other offices. Operations and Results During Fiscal Year. Work accomplished at the Waterways Experiment Station is, in general, initially financed by a revolving fund, reimbursement being obtained directly from agencies for whom work is performed. Cost for operation of station for fiscal year 1970 was $22,789,362, of which $19,789,299 was charged to establishments served for research investigations and related services, and $3, 000,063 for permanent improvements and equipment. Of the reimbursable work, $6,255,277 was charged to civil funds, $13,413,092 to military funds, and $120,930 to nongovernmental agencies. Work includes $2,039, 247 performed by contract. Total cost incurred for operation of the Waterways Experiment Station to June 30, 1970 was $265,093,711, of which $248,243,499 represents reimbursable cost and $16,850,212 the unamortized cost of permanent improvements and equipment. 1273 PERMANENT INTERNATIONAL ASSOCIATION OF NAVIGATION CONGRESSES The United States by act of June 28, 1902, appropriated $3,000 a year for support and maintenance of the Permanent International Commission of Navigation Congresses and for payment of the actual expenses of properly accredited national delegates of the United States to meetings of the Congresses and Commission. An increase in the appropriation of $5, 000 annually was authorized by 1948 River and Harbor Act. The 1965 River and Harbor Act authorized an appropriation of $22,000. Of this amount, $2,375 is paid by the American Section directly to the International Association with headquarters in Brussels, Belgium. The objective of the Association-to promote the progress of inland and maritime navigation-is met by holding International Congresses and publishing technical bulletins and other documents. The Congresses are held in various member countries, usually at 4-year intervals. The Association is supported principally by member governments, but membership also extends to corporations and individuals. Member governments are represented at the Congresses and at meetings of the Permanent International Commission by delegates, the number of official delegates to be determined by the amount of the annual subsidy paid by the government, but not to exceed 10 in number. Corporate members may send one official representative to the Congresses. Individual membership is of two classes-Annual and Life, depending on the method of payment of dues. The affairs of the Association are managed by the Permanent International Commission composed of delegates from the supporting governments. The National Commission constitutes the governing body of the American Section and the U. S. members of the Permanent International Commission. The Director of Civil Works, Office of the Chief of Engineers, U. S. Army; and Resident Member, Board of Engineers for Rivers and Harbors, are the ex-officio Chairman and Secretary, respectively, of the National Commission. The Secretary handles all administrative matters of the American Section. During fiscal year 1970, the National Commissioners were: Maj. Gen. F. P. Koisch, USA' ex-officio Chairman; Co. A. D. Wilder, CE, USA, ex-oficio Secretary; Mr. Jerome O. Ackerman; Col. Carl H. Bronn, USA (Ret.); Mr. Braxton B. Carr; Mr. Mark S. Gurnee; Mr. J. W. Hershey; Mr. Joseph H. McCann; Mr. Duane Orr; and Mr. Theodore M. Schad.d. Brig. Gen. Herbert D. Vogel, USA (Ret.), and Mr. Carl B.. Jansen are honorary members of the Commission. The annual meeting of the Permanent International Commission was held in Lisbon, Portugal, on May 19, 1970, and was attended by the 10 National Commissioners and Maj. Gen. Charles G. Holle USA (Ret.), the Honorary Member of the Permanent International Commission from the United States. Membership of the American Section on June 30, 1970, totaled 712, consisting of 641 individuals and 63 corporate members. A total of 40 new individual members and 8 new corporate members were added during the fiscal year, and 1 life and 64 individual members deleted either through resignation, death, or non-payment of dues. Federal funds from annual appropriations were expended as follows: Annual U. S. Contribution to Association, $2,375; expenses of representatives to annual meeting in Lisbon, $6,049; publications, $25; total obligations, $8,449. 1275 INVESTIGATIONS AND SUPERVISION OF PROJECTS UNDER FEDERAL WATER POWER ACT The Federal Water Power Act of June 10, 1920, created the Federal Power Commission, composed of the Secretaries of War, Interior, and Agriculture, with authority to grant permits and licenses for hydroelectric developments in all waters over which Congress has jurisdiction. The act further required that work of the Commission be performed 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 an 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 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 Senate. The necessity of performing work through the Departments of War, Interior, and Agriculture was removed and the Commission authorized to appoint such officers and employees as necessary in executing its functions. By title II, Public Utility Act of 1935, the original Federal Water Power Act was made part I of the Federal Power Act, and parts II and III added to that act. The law also provides that no waterpower license affecting navigable capacity of any navigable waters of the United States shall be issued until plans of the dam or other structures affecting navigation have been approved by the Chief of Engineers and the Secretary of the Army. There is further provision whereby any person or corporation intending to construct hydroelectric project works in any stream over which Congress has jurisdiction, other than navigable waters, shall file a declaration of intention for the purpose of ascertaining whether or not jurisdiction of the Federal Power Commission will attach. The following work of an engineering nature was assigned and accomplished during the fiscal year: 23 plans approved by Chief of Engineers and Secretary of the Army in accordance with sec. 4 (e) of the Federal Water Power Act; 33 reports submitted on applications for preliminary permits or licenses or amendments thereto and reports on licensed projects subject to recapture; and 8 licenses under supervision. Necessary expenses in excess of nominal amounts for transportation and subsistance of personnel engaged in investigations and cost of supervision under provisions of the Federal Power Act are paid from appropriations made for the Power Commission. All other costs of administration of laws in question are paid from funds available for general expense of the Corps of Engineers. No expenses were paid from appropriations made for the Federal Power Commission during the fiscal year. 1277 451-584 0-72-81 MISCELLANEOUS CIVIL WORKS IMPROVEMENTS TABLE OF CONTENTS Page 1.

All other tables are referenced in text and also appear at the end of this chapter. 1279 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Funds: For funds with which the miscellaneous civil works were prosecuted during the fiscal year see Table 48-A. 2. INTERNATIONAL BOUNDARY WATERS BOARDS. In order to carry out United States obligations under international agreements, the Office of the Chief of Engineers and several Divisions and Districts of the Corps with jurisdiction over areas bordering Canada, have representation on numerous Boards and Committees. The majority of these Boards are established by the International Joint Commission (IJC) as empowered in accordance with the provisions of the Boundary Waters Treaty of 1909 between the United States and Great Britain (Canada). IJC Boards fall into two broad categories; boards of control, which are more or less permanent; and engineering or technical boards, which are usually dissolved after completing their assignment. In addition to Boards created by the Commission other boards and committees are created by treaties or other informal arrangement in matters concerned with the water resources, and the members report directly to the Government or establishing agency. A listing of the Boards having Corps of Engineers membership follows: 2A. THE INTERNATIONAL ST. CROIX RIVER BOARD OF CONTROL Constitution and duties. The Board was organized pursuant to conditions in the orders of the International Joint Commission approving the maintenance and operation of the dam built by the St. Croix Water Power Co. and the Sprague Falls Manufacturing Co., Ltd., across the St. Croix River at Grand Falls, Maine, and subsequent agreements reached between the Governments of the United States and the Dominion of Canada. The Board is charged with the duty of formulating and administering rules under which the power plant and accessories are to be operated to prevent as nearly as possible a level of water at the dam higher than 203.5 (mean sea level datum), and to secure the users of water below Grand Falls the flow of water to which they are entitled. The Board is also charged with the supervision of the operation of all fishways on that portion of the St. Croix River that forms the international boundary. On October 2, 1934, the International Joint Commission issued an order approving the reconstruction of the dam by the Canadian Cottons, Ltd., extending across the St. Croix River from Milltown, New Brunswick, Canada, to Milltown, Maine, which contained the following conditions: (a) the reconstructed dam to be operated to insure that the forebay levels rise to no higher elevation than that which was obtained in the operation of the dam now being replaced; (b) during floods the sluiceways of the dam shall be sufficiently open to insure passage of the river flow; and (c) the operation of the dam, insofar as is necessary to insure the observance of the provisions of this Order, be under the supervision of the International St. Croix River Board of Control. On November 19, 1965, the Commission directed the Board of Control, in addition to the duties previously assigned, to carry out the duties contained in the Order of Approval dated October 15, 1965, for the construction of the storage dam at Vanceboro and requested that future reports be submitted semi-annually. Members of the Board for fiscal year. Colonel Frank P. Bane, Division Engineer, U. S. Army Engineer Division, New England, Waltham, Massachusetts, United States Member, and Mr. John E. Peters, District Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, Ottawa, Ontario, Canadian Member. Operations during fiscal year. Supervision was maintained and inspections were made by the Canadian and the United States members to ensure that the Orders of Approval of the International Joint Commission were carried out. The New Brunswick Electric Power Commission completed the erection of Unit Number 7, a 500 KW generator in its Milltown Generating Station in December 1969. The Georgia-Pacific Corporation reports that the construction of its 31,000 KVA, O.9pf thermal electric generating unit at Woodland, Maine, is expected to be completed during the fall of 1970. During the period October - December 1969, the Georgia-Pacific Corporation reconstructed their timber storage dam at the outlet of East Grand Lake. Water Survey of Canada reports that the telemark equipment has been installed in the Baring International Gauging Station in cooperation with the United States Geological Survey. The Board of Control has been advised that first order levelling will be extended to the Grand Falls Dam by the Precise Levelling Section, Department of Energy, Mines and Resources, Canada, in 1971, or earlier, if survey programs can be adjusted. On July 23, 1969, the United States and the Canadian members met with officials of the New Brunswick Electric Power Commission and the Georgia- Pacific Corporation. They toured the facilities of the Corporation including the pollution control structures under construction at Woodland as well as the Milltown Generating Station of the New Brunswick Electric Power Commission. In the spring of 1970 high precipitation occurred over the East Branch St. Croix River. This, coupled with melting snow, caused Spednick and East Grand Lakes to fill in April and May. East Grand Lake on May 18, 1970, slightly exceeded the maximum established by the Commission, namely Elev. 434.94, but was immediately lowered by the owner. 1280 MISCELLANEOUS CIVIL WORKS Proposed operations. Such correspondence and inspection as may be necessary to carry out the Orders of Approval of the InternationaJl oint Commission will be continued. 2B. INTERNATIONAL SAINT JOHN RIVER ENGINEERING BOARD Construction and duties. The Board was established September 28, 1950 by the International Joint Commission to determine if the waters of the Saint John River system could be more beneficially conserved and regulated. The Board's report was submitted to the Commission in April 1953. It outlined several projects, the development of which would be practical and in the public interest. The Commission submitted its interim report to the two governments in April 1954. Since then the services of the Board have been retained to advise the Commission, keeping the latter informed at least annually on any resource developments being undertaken or proposed by entities in either country. Members of the Board for fiscal year. The Board consists of four members, two from each country. The Canadian representatives were Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, Ottawa, Ontario, Chairman of the Canadian Section and Mr. J. E. Bright, Regional Director, Atlantic Region, Department of Public Works, Halifax, Nova Scotia. The United States representatives were Mr. E. L. Hendricks, Chief Hydrologist, Water Resources Division, U. S. Geological Survey, Washington, D. C., Chairman of the United States Section and Mr. F. L. Thrall, Engineer, Planning Division, U. S. Army, Office, Chief of Engineers, Washington, D. C. Operations during fiscal year. The Board did not meet during the year, but it reviewed developments within the basin and reported to the International Joint Commission on activities of new Brunswick Power Commission, unchanged status of the Dickey-Lincoln School project, status on sewage treatment facilities in the basin, setting of water quality and' uses classification on the river by the State of Maine, status of small boat hydrographic charting, that the Canada- New Brunswick Saint John River Basin Agreement for resource development was signed June 30, 1970 and a major flood occurred in February 1970. 2C. INTERNATIONAL LAKE MEMPHREMAGOG BOARD Constitution and duties. Lake Memphremagog is in northern Vermont and southeastern Quebec and has as its outlet Magog River in Canada. In 1920, a petition filed by the city of Newport and towns of Derby, Coventry, and Barton, Vt., alleged they had been harmed by high lake levels attributable to construction and operation of power plants on the Magog River. As a result, the international board composed of one engineer each from the United States and Canada was appointed to consider the matter and submit a joint report to each Government as to the level or levels at which Lake Memphremagog should, so far as possible, be maintained. At the request of local interests, consideration of the problem was suspended until 1931 when a survey was made. Subsequently a joint report by the two members of the Board, dated May 14,1934, was submitted to their respective Governments. This report recommended that the levels of the lake under normal flow conditions range between an upper elevation of 682.70 feet above mean sea level (Geodetic Survey of Canada, 1923 adjustment), and a lower limit of 678.98 feet above the same datum. During flood conditions, the sluiceways of the dam shall be so operated as to reduce the flood water elevations to the normal regulated level of 682.70 as rapidly as possible. The Board was reactivated by both Governments August 12, 1960 as a result of a complaint on July 20, 1959, by a resident of Newport, Vt., concerning high lake levels due to alleged improper operation of the power plant. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Staff Officer, Assistant Deputy Minister (Water), Department of Energy Mines and Resources, for Canada and Col. Harvey L. Jones, District Engineer, U. S. Army Engineer, District, New York for the United States for the period July 1 - 16, 1969 and Col. James W. Barnett for the remainder of the fiscal year. Operations during fiscal year. Supervision of the levels was maintained. A Stevens Telemark signal answering instrument was installed at the Magog Wharf gaging station by the Water Survey of Canada to furnish instantaneous water level elevations referred to the Old Datum of the Geodetic Survey of Canada which is 0.13 feet less than 1923 adjustment. The Water Resources Branch of the U. S. Geological Survey records daily readings of the elevation of Lake Memphremagog at Newport Vt. Datum of the gage is 673.00 feet above mean sea level, U. S. Geological Survey 1929 adjustment which is 0.30 feet higher than the Geodetic Survey of Canada, 1923 adjustment. 2D. INTERNATIONAL LAKE CHAMPLAIN BOARD OF CONTROL Constitution and duties. The Board was organized pursuant to the provisions of the Order of Approval, dated June 10, 1937, of the International Joint Commission, approving construction and operation of certain remedial works in Richelieu River at Fryer's Island, Quebec. The Board is responsible for insuring compliance with provisions of the order of approval insofar as they relate to the regulation of the levels of Lake Champlain. Members of the Board for fiscalyear. Mr. N. P. Persoage, Inland Waters Branch, Department of Energy, Mines and Resources, for Canada, and Col. Harvey L. Jones, District Engineer, U. S. Army Engineer District, New York, for the United States for the period July 1 - 16, 1281 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 1969 and Col. James W. Barnett for the remainder of the fiscal year. Operations during fiscal year. The wall of the lock at St. Johns, which had collapsed, was rebuilt in June 1970. Studies have been continued by the Canadian Department of Transport to determine the best method of maintaining navigation between the Chambly Basin and St. Johns, Quebec, in view of the rapidly deteriorating condition of the Chambly Canal. Further experiments may be carried out with low head at the Fryer's Island dam whereby some water will be impounded to improve conditions at Ile Ste. Therese. The effect of any such operation will not extend upstream of the rapids located between Ile Ste. Therese and St. Johns. 2E. INTERNATIONAL ST. LAWRENCE RIVER BOARD OF CONTROL Constitution and duties. The Board was established December 16, 1953 pursuant to the provisions of the Order of Approval dated October 29, 1952, of the International Joint Commission for the construction of certain works for the development of power in the International Rapids Section of the St. Lawrence River. The Commission instructed the Board to perform the duties assigned to it by the Order of Approval. These responsibilities include the following items: (a) The Board of Control is to determine the gages, measurements and other services to be provided by the Power Authority of the State of New York and the Hydro-Electric Power Commission on Ontario in order to furnish accurate records relating to water levels and the discharge of water through the works and the regulation of the flow of water through the International Rapids Section; (b) Upon completion of the works the duties of the Board shall be to insure that the provisions of the Commission's Orders relating to water levels and the regulation of the discharge of water from Lake Ontario and the flow of water through the International Rapids Section are complied with, and the Hydro-Electric Power Commission of Ontario and the Power Authority of the State of New York shall duly observe any direction given them by the Board of Control for the purpose of insuring such compliance. The Board of Control shall report to the Commission at such times as the Commission may determine; (c) In addition to the reports to be made by the Commission in accordance with the terms of the Orders of Approval, the Board was requested to report at the Commission's semi-annual meetings and also to keep the Commission currently informed with regard to the discharge of water from Lake Ontario and the flow through the International Rapids Section of the St. Lawrence River; and (d) At a meeting of the International Joint Commission in Toronto on January 25, 1957, studies of the regulation of Lake Ontario in furtherance of such studies accomplished by the Intei national Lake Ontario Board of Engineers, were assigned to the Board of Control. The Canadian members were: Mr. D. M. Ripley, Director, Marine Hydraulics Branch, Department of Transport, Chairman of the Canadian Section; Mr. J. B. Bryce, Hydraulic Engineer, Hydro-Electroic Power Commission of Ontario; Mr. Y. DeGuise, Commissioner, Hydro-Electric Power Commission of Quebec; and Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of -Energy, Mines and Resources. The United States members were: the Division Engineer, U. S. Army Engineer Division, North Central, Chairman, exofficio, U. S. Section; Mr. Thomas M. Crum, Deputy to the Chief, Division of Licensed Projects, Federal Power Commission; Mr. J. B. McMorran, Commissioner, Department of Transportation, State of New York; and Mr. F. F. Snyder, Hydraulic Engineer. U. S. Army, Office, Chief of Engineers, (Retired). Brigadier General W. W. Watkin, Jr. was North Central Division Engineer during the fiscal year, Mr. R. D. Conner, Power Authority of the State of New York replaced by Mr. McMorran effective on June 5,1970. Operations during fiscal year. During the fiscal year the Board met twice and presented two semi-annual reports to the IJC. At its appearance before the Commission on October 1, 1969, the Board presented a statement concerning the low water levels experienced on Lake St. Lawrence during the summer of 1969. In reply to the complaints from and on behalf of riparian owners about low lake levels and requests for action to increase the water level of Lake St. Lawrence, the Commission, on October 9, 1969 issued a press release explaining the situation on Lake St. Lawrence. The Commission instructed the Board to investigate and report on the possibilities and consequences of providing for a measure of emergency relief, on a temporary basis, for those affected and to advise the Commission. The Board investigated two methods, ponding and discretionary deviations, which might provide relief whenever regulation would result in Lake St. Lawrence levels below a selected elevation. The conclusion subsequent to this investigation was that deviations from Plan 1958-D by the Board's discretionary authority may, in some years, be a feasible method of improving the low water levels of Lake St. Lawrence during the recreational seasons. The Board will continue to keep this matter under review and be prepared to exercise its discretionary authority, upon recommendations of its Regulation Representatives and Operations Advisory Group, as to when such deviations are feasible and when payback should occur. The Board of Control approved two reports of its Committee on River Gaging, which provides and maintains a comprehensive program for recording river levels and flows and advises the Board. The Power Entities have installed the necessary gages requested to date and the required records are being obtained. The levels and overflows of the St. Lawrence project have continued to be regulated in accordance with the 1282 MISCELLANEOUS CIVIL WORKS International Joint Commission's Orders of Approval dated October 1952 and July 2, 1956, known as "Regulation Plan 1958-D." The supplies to the Great Lakes have remained generally favorable during the reporting period. There were no violations of the approved range of state on Lake Ontario during the reporting period. Peaking tests were continued throughout the period and ponding was authorized during the non-navigation season. There has been no system emergency requiring additional flow during the winter season. The Board was advised of a metering program planned jointly by the St. Lawrence Seaway Development Corporation and the St. Lawrence Seaway Authority. This program was carried out during the spring of 1970 by the Water Survey of Canada and the U. S. Lake Survey, Corps of Engineers. The program involved flow measurements on the St. Lawrence River at Massena Point and in the North Channel below Pollys Gut. The Board had requested its Regulation Representatives to assist in effecting the necessary coordination with the Power Entities so that the required periods of flow stabilization could be programmed to produce minimum effect on power production. No problems related to ice formation were encountered during the winter. The Board has noted the possibility in the event that the navigation season is extended on the St. Lawrence that certain works would need to be provided to assure that such extension could be accomplished without adversely affecting the interests concerned. The Board had requested its Operations Advisory Group to take this matter under consideration and submit a brief thereon. 2F. INTERNATIONAL NIAGARA BOARD OF CONTROL Constitution and duties. The Board was established August 19, 1953 by the International Joint Commission to supervise the construction, maintenance and operation of the Niagara Remedial Works, recommended by the Commission in its 1953 report on the "Preservation and Enhancement of Niagara Falls." Members of the Board for fiscal year. The United States Members of the Board were the Division Engineer, U. S. Army Engineer Division, North Central, ex-officio Chairman, U. S. Section; and Mr. T. M. Crum, Deputy to the Chief, Division of Licensed Projects, Federal Power Commission. Brigadier General W. W. Watkin, Jr. was North Central Division Engineer, during the fiscal year. The Canadian Members of the Board were Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, Chairman of the Canadian Section and Mr. G. Millar, Chief Engineer, Harbors and Rivers Engineering Branch, Department of Public Works. Operations during fiscal year. The Board met three times during the fiscal year and presented two semi- annual reports to the IJC. In 1968 the Power Entities had recommended to the Commission that a later date be considered for removal of the Niagara River - Lake Erie ice boom. The Board investigated this and reported its findings to the Commission. The Commission held a public hearing in 1969 to receive testimony and evidence from interested parties as to the desirability of providing more flexibility regarding the dates when the ice boom is to be installed and removed. Based upon the findings of the Board's investigation and the hearing, by Supplementary Order dated October 3, 1969 the Commission further amended its Order of Approval of June 9, 1964 in the matter of the Niagara River - Lake Erie ice boom providing flexible dates for closing the boom in the fall and opening it in the spring in accordance with weather and ice conditions. The ice boom was fully reinstalled on Decednber 10, 1969 and removed by April 30,1970. The experience gained during the 1969-70 operations of the boom has shown in particular that the delaying opening of the boom beyond the first Monday in April, as formerly specified, was beneficial this year to both shore property and power interests on the Niagara River with no material detrimental effects to navigation on Lake Erie. Over the past six winters the ice boom has functioned successfully. During the past fiscal year the gates in the control structure have been operated to maintain the pool within the limits set by the Board. On days when there are ice runs or storms the normal operating limits for the Chippawa-Grass Island Pool may be suspended temporarily and, under such circumstances, the Power Entities diverting water from the pool are expected to use their best judgment in operating the gates. The Board, assisted by regular reports from its Working Committee, has closely observed the operation of the control structure to assure that operation of the structure was in accordance with the Board's instructions. The Board has encountered no unusual maintenance problems during the year. Although the study of means of preserving or enhancing the scenic beauty of the American Falls is primarily a function of the American Falls International Board, some aspects of that study are pertinent to the International Niagara Board of Control because of their possible effects on levels of the Maid-of-the-Mist pool, Grass Island pool, etc. Additional temporary diversions from the Niagara River for power production purposes were allowed during the period that a temporary cofferdam was in place. As requested by the Commission in its letter dated June 13, 1969, the Board submitted to the Commission by letter dated January 12, 1970 its determination of total contribution, in cash or in services, which the Power Authority of the State of New York and the Hydro-Electric Power Commission of Ontario will 1283 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 make toward the cost of the American Falls study due to the diversions. The computed contribution from each entity was $276,500 in the currency of its country. By letters dated February 24, 1970 the Commission informed the Board that the recommended amount was approved. Eighteen discharge measurements were made at the Austin Street Section of the Niagara River during the first part of the Fiscal Year to delineate the full range of weed effect on the Fort Erie gage. Twelve additional discharge measurements were carried out at the Stella Niagara Section during pre-arranged steady flow conditions through the power plants in October, November and December 1969. These measurements were made to provide an indirect determination, under steady flow conditions, of the discharge past the Ashland Avenue Gage. A study to investigate a proposal to establish an aerial metering cableway in the lower Niagara River immediately upstream of the Robert Moses Power Plant is underway. If this proposal is feasible then flow past the Ashland Avenue Gage can be measured directly instead of indirectly as is done presently by subtracting the outflows of the powerhouses from the discharge at the Stella Niagara Section. Also, the Board intends to carry out tests to study possible backwater effects of power operations on Lake Erie. These tests that started in December 1969 were cancelled because of unfavorable weather conditions and they will be rescheduled during the fall of 1970. The Board of Control is concerned about the accumulative effect of existing and proposed fills along shoreline of the Niagara River. The Board is studying the effects of such fills on levels of the Niagara River, and will report the results when completed. The Commission in August 1969 asked the Board to investigate a request by a Rowing Club located at Buffalo, New York to install an ice boom in the Black Rock Channel for the purpose of reducing the amount of ice which passes into the channel after the Lake Erie ice boom is opened. The Board has completed its investigation and will furnish its report on this matter in July 1970. 2G. INTERNATIONAL NIAGARA COMMITTEE Constitution and duties. The Treaty of 1950 between Canada and the United States concerning the uses of waters of the Niagara River was signed on February 27, 1950. By its provisions, limitations on the diversions of Niagara River water for power in accordance with Article V of the Treaty of 1909 are terminated and temporary international agreements for the allocation of waters of the Niagara River for power purposes are replaced. In accordance with provisions of Article VII of the 1950 Treaty, a representative was appointed by each government who, acting jointly, shall ascertain and determine the amounts of water available for the purposes of this treaty, and shall record the same and shall also record the amounts of water used for power diversions. By an exchange of -notes during January 1955, the two Governments officially designated the representatives appointed in conformance with Article VII of the 1950 Treaty as the International Niagara Committee. With regard to flows and diversions, the Treaty of 1950 became effective October 10, 1950. Under terms of the Treaty, all waters in excess of certain minimum flows which are required to maintain the scenic spectacle at Niagara Falls are available for diversion for power and, with the exception of the 5,000 cubic feet per second authorized October 1940 for diversion by Canada, are to be allocated equally between both countries. Minimum flows over the Falls shall not be less than 100,000 cubic feet per second between 8 a.m. and 10 p.m. E.S.T. from April 1 to September 15, and 8 a.m. to 8 p.m. from September 16 to October 31. At all other times the flow over the Falls shall not be less than 50,000 cubic feet per second. A brief history regarding the measurement and supervision of diversion of waters from the Niagara River prior to the designation of the representatives appointed under Article VII of the 1950 Treaty as the International Niagara Committee is included in the Annual Report for 1955. Members of the Committee forfiscalyear. The Committee consists of two members. Mr. R. H. Clark, Special Advisor to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, and the U. S. representative, ex-officio, was the Division Engineer, U. S. Army Engineer Division, North Central, Brigadier General W. W. Watkin, Jr., North Central, was Division Engineer during the fiscal year. Operations during fiscal year. The Committee received daily reports of operation of the hydro-electric generating stations on the Niagara River which diverted water from the river above the Falls, and the DeCew Falls Plant, which diverts water from Lake Erie through the Welland Canal. These reports, submitted in the form prescribed by the Committee and showing for each hour the quantities of water diverted by each plant, were checked by the Committee. Monthly and annual summaries were prepared. The Committee included with each monthly summary an explanation of any treaty violation which may have occurred during the month. The Committee has computerized its monthly report in the interest of accuracy and efficiency. Bi-weekly and intermittent inspections of all plants were made by representatives of the Committee jointly and individually to obtain independent watt meter readings of power output. Records of water levels in the Niagara River above and below the Falls were obtained by means of self-registering gages. However, the American Falls channel water level gage used for the purpose of determining flows over the American Falls has been providing inconsistent data since the dewatering of the Falls in 1969. Thes inconsistencies which have been attributed to modifications made to the gage intake at the time the American Falls channel 1284 MISCELLANEOUS CIVIL WORKS was dewatered, require a precise recalibration of the installation. For the purpose of this recalibration, a set of discharge measurements are planned to be made during the fall of 1970 or the spring of 1971. In a separate exchange of notes on March 21, 1969, the Governments of the United States and Canada authorized the construction of a temporary cofferdam between the Goat Island and the United States mainland to permit investigation of measures that may be desirable to preserve or enhance the beauty of the American Falls and provided an agreement for additional temporary diversions from the Niagara River for the power production purposes. The investigation under the terms of the note was to be completed and the cofferdam removed no later than December 1969. The notes for additional diversion permitted for power purposes state that minimum flows over the Falls stipulated in Article IV of the Niagara River Treaty of 1950 shall be reduced from 100,000 and 50,000 cfs, respectively, to 92,000 cfs and 41,000 cfs, during the hours designated in that Article. Any water in excess of these new temporary minimums may be diverted for power purposes; provided that when the 41, 000 cfs minimum applies at least 9,000 cfs of the waters thus diverted shall be either passed through the low head plants or released to the Horeshoe Falls so as to maintain a minimum flow of 50,000 cfs into the Maidof- the-Mist Pool at all times. Power benefits derived from this temporary arrangement under the terms of the note were divided equally between the Power Authority of the State of New York and Hydro-Electric Power Commission of Ontario, who in return have provided sizeable contributions to the cost of the cofferdam and ensuing study. The deviation from the Treaty flow started on June 12, 1969 when the cofferdam was completed until November 29, 1969 when the cofferdam was removed. It had originally been scheduled to keep the Falls dewatered until the end of December 1969, however, the field work was completed early and the Niagara River was allowed to resume its normal course on November 29,1969. 2H. AMERICAN FALLS INTERNATIONAL BOARD Constitution and duties. In a Reference dated March 31, 1967, the Governments of the United States and Canada, pursuant to Article IX of the Boundary Waters Treaty of 1909, requested the International Joint Commission to investigate and report upon measures necessary to preserve and enhance the beauty of the American Falls at Niagara. The American Falls International Board was established July 24, 1967, by the International Joint Commission to carry out the investigations required under the Reference. Members of the Board for fiscal year. The U. S. members of the Board were the Division Engineer, ex-officio, U. S. Army Engineer Division, North Central, Chairman of the U. S. Section; and Mr. Garrett Eckbo, Chairman, Department of Landscape and Architecture, University of California, Berkeley, Brigadier General W. W. Watkin, Jr. was North Central, Division Engineer, during the fiscal year. Canadian members were Mr. T. M. Patterson, Special Advisor to Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, Chairman of the Canadian Section, and Mr. H. S. M. Carver, Chief Advisory Group, Central Mortgage and Housing Corporation, Ottawa, (Retired). Operations during fiscal year. In an exchange of notes, dated March 21, 1969 between Canada and the United States which temporarily amended the Niagara Treaty of 1950, a minimum flow over the Falls of 92,000 cfs instead of 100,000 cfs during the tourists hours and 41, 000 cfs instead of 50,000 cfs during the non- tourist hours was allowed. The Power Entities were authorized to utilize the extra water and they begin additional diversions on June 11 as a cofferdam was being completed allowing for dewatering of the Falls. All additional diversions ceasing before 3:00 PM on November 28 as the cofferdam was being removed. The Governments of Canada and the United States approved the procedures for contributions to be made by the Power Entities for the use of the extra water. Under these procedures certain advances and periodic payments were to be made by the Power Entities to the Buffalo District Engineer on condition that the monies be supplied directly to the American Falls studies in the form of salaries, travel expenses, materials, equipment or other work, and having prior approval of the American Falls International Board. The Board approved of specific work items from Ontario-Hydro with a contribution value of $121,365 and from the Power Authority of the State of New York with a contribution value of $4,000. Following restoration of flow to the American Falls, the International Niagara Board of Control determined the total contribution from each Power Entity and advised the Commission. The Power Entities agreed to the amounts determined by the Board and the amounts were approved by the International Joint Commission. These contributions amounted to $276,500 for each Entity in the currency of its country. The American Channel was completely dewatered for study from June 12 to November 25,1969. The following is a summary of major geologic exploration activities accomplished during the channel dewatered period: a. A total of 46 core borings were completed for a total footage of 4,882 feet of core. b. Pressure testing and hydrologic and tracer testing were performed on the completed holes. Piezometers were installed in three holes. c. The field phase of the face mapping consisting of topographic, stratigraphic and structural studies was completed. 1285 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 d. The field survey portion of the terrestrial photogrammetry of the face of the American Falls was completed. e. On-site structure and joint studies of the dewatered river bed was completed. f. The field talus studies which were completed included examination of the cobbles and boulders to determine rock type and condition. A seismic survey was made to determine the depth of the talus which was found to be about 75 feet. The data obtained is being compiled and analyzed. Some preliminary observations made as to the geologic character and condition of the American Falls: a. The degree of undermining is not as severe as had been anticipated. b. There appear to be two types of mechanisms of failure. In the 1931 rockfall the Rochester shale apparently was removed to a significant degree prior to failure which occurred principally as a downdropping and the talus accumulated close to the area of the rockfall. In the July 1954 rockfall apparently less undermining occurred prior to failure that appears to have been a downward movement of the rock mass followed by a considerable amount of outward rotation, spreading the talus accumulation from the rockfall area to the Maid-of-the-Mist Pool. c. There is one large rock mass near Prospect Point that has become detached to a greater degree than previously realized. In size it is about 38,000 tons, approximately half the size of the 1931 rockfall. The detached rock appears to have been pulled apart as a result of cohesion to a previous rockfall. The stability of that area probably is lower than that of other areas. Because of the concern expressed on the effect of the dewatering on the ecology of the area, a report was prepared by Dr. Alfred Beeton entitled "Observations on the Ecology of the Niagara River and American Falls". The conclusion was that the dewatering did not have any detrimental effect on the ecology of the area. Members of the Board and its working Committee visited the American Falls area several times during the dewatered period. At a meeting held in Niagara Falls, Ontario on March 6, 1970 the Board discussed a proposal to design a weir at the outlet of the Maid- of-the-Mist Pool to raise the level of the Pool. The Board also discussed the development of a hydraulic model of the Falls for use in developing alternative treatments of the talus. The model was approved and to be so designed as to allow easy manipulation of the various talus treatments. On April 23, 1970, the Buffalo District Engineer was alerted and asked by .the Niagara Frontier State Parks Commission of New York State to investigate an apparent slope failure at Luna Island. Subsequent to a meeting attended by study participants and many agencies it was agreed that study of three adjace nt areas, Prospect Point, Luna Island and Terrapin Point is necessary. As a result of this meeting the Niagara Frontier State Parks Commission officials have asked that the Board's studies of the American Falls be extended to cover in more detail the three areas which are suspect of structural weaknesses. The Board agreed to inform the International Joint Commission of the requested expanded study to investigate the stability of adjacent areas of the Niagara Gorge wall at and in the vicinity of the American Falls and to seek guidance on the boundaries of the study under the Reference of March 31,1967. 21. INTERNATIONAL GREAT LAKES LEVELS BOARD Constitution and duties. The Governments of Canada and the United States, by Reference dated October 7, 1964, requested the International Joint Commission to determine whether measures within the Great Lakes Basin can be taken in the public interest to regulate further the levels of the Great Lakes or any of them and their connecting waters so as to reduce the extremes of stages which have been experienced, and for the beneficial effects in these waters. The Reference further stated that the two Governments will upon request make available to the Commission the services of engineers and other specifically qualified personnel of their governmental agencies And such information and technical data as may have been acquired by them during the course of the investigation. At a meeting on December 2,1964, the International Joint Commission established the Board to undertake the necessary investigations and studies and to advise the Commission on all matters which it must consider in making a report or reports to the Government under the Reference. At the first meeting of the Board on January 6,1965, a Working Committee was selected. The Working Committee met on July 7,1965 and set up four Subcommittees to investigate and report on the separate areas of study involved: Shore Property, Navigation, Power and Regulation. A Subcommittee on Regulatory Works was subsequently established by the Working Committee in September 1967 and a Reports Subcommittee in June 1968. The Study program is being considered in two broad phases: the first phase consists of the collection and compilation of basic data, the development of methodology for evaluating regulation plans in respect of their effects on the various Great Lakes interests, the investigation of regulation techniques and the preparation of preliminary plans. The work involved in this phase has been largely accomplished. In the second phase, necessary political and legal restraints to regulation will be identified and applied in the development of alternative practical regulation plans. Concentrated work efforts are being applied to obtain the cost data for regulatory works required. Members of the Board for fiscal year. United States members of the Board were Mr. L. G. Feil, Chief of 1286 MISCELLANEOUS CIVIL WORKS Planning Division, Civil Works, Office, Chief of Engineers, U. S. Army, Chairman of the United States Section; Mr. M. Abelson, Regional Coordinator, Northeast Region, Department of the Interior; and Mr. B. T. Jose, Assistant Administrator, St. Lawrence Seaway Development Corporation, Department of Transportation. Canadian Members of the Board were Mr. T. M. Patterson, Special Advisor to Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, Chairman of the Canadian Section; Mr. C. K. Hurst, Chief, Maintenance and Operations, Harbors and Rivers Engineering Branch, Department of Public Works; and Mr. R. H. Smith, Chief, Hydraulics Study Division, Department of Transport. The Working Committee consists of seven members, four representing the United States and three representing Canada. U. S. Members of the Working Committee were Brigadier General W. W. Watkin, Jr., Division Engineer, North Central, Chairman, ex-officio, U. S. Section; Mr. Mark Abelson; Mr. A. J. Buchar, Director of Field Service, Chicago Field Office, Department of Commerce until April 13, 1970 when he retired and was replaced by Mr. Michael V. Simon, Trade Specialist, Chicago Field Office, Department of Commerce; and Mr. J. H. Spellman, Deputy Regional Engineer, New York Regional Office, Federal Power Commission. Canadian Members of the Working Committee were Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, Chairman of the Canadian Section; Mr. D. W. Quinlan, Chief Engineer, Planning, Department of Public Works; and Mr. John Bathurst, Special Project Engineer, Department of Transport until March 5, 1970 when he was replaced by Mr. C. J. R. Lawrie. Six subcommittes have been formed with membership drawn from agencies participating in the study and represented on the Board and Working Committee. Operations during fiscal year. Methodologies have been finalized for providing monetary evaluation of the effects of Great Lakes level fluctuations on shore property, navigation and power interests. Optimization techniques are being used to establish the maximum net benefit which could be expected from regulation of- these lakes. A computer program has been developed for this purpose and is being used in the testing and preliminary design of improved regulation plans. The Regulation Subcommittee has developed and the other Subcommittee have evaluated several preliminary four-lake, three-lake and two lake regulation plans. A preliminary no-cost for regulatory works Lakes Superior-Ontario regulation plan has been developed by the Regulation Subcommittee and provided to the other subcommittees for their detailed assessments. An investigation for increasing the flexibility of Lake Superior is continuing, specifically, to determine the ability to pass winter flows in excess of 85,000 cfs. If the test prove the feasibility of higher winter flow, regulation plans will be developed with higher maximum winter outflows. A comparison will be made between the cost of operating control gates in winter to achieve the higher flows and the economic benefit which would ensue therefrom. A second winter of experimental operation of the gates of the Lake Superior Control Works at Sault Ste. Marie was completed during the 1969-1970 winter. Eight additional gates were opened providing a total flow of 95, 000 cfs. Sufficient knowledge and experience was gained to verify that the guides could be decided to permit gate movement under adverse conditions. Under the conditions prevailing during the experiment, the tests have demonstrated that a winter flow of 95,000 cfs is possible through the gates and St. Marys River without ice jamming problems. It is planned to continue the tests during future winters to verify the feasibility of passing a flow of 95,000 cfs under a variety of winter conditions. A study of consumptive use of water within the Great Lakes basin was completed and filed with the Commission. The report contains a projection of this use of the year 2030. Upon completion and acceptance of final recommended regulation plans by the Board, the plans will be retested with a reduced water supply (reflecting the projection of consumptive use) and the effects on the stages and flows determined. Development of preliminary criteria for regulation continued. The preliminary criteria will be subject to considerable subsequent modification as a result of future economic evaluation and further considerations in regard to the requirements of the various interests concerned with lake regulation. A Style and Format Manual has been prepared to be used as a guide for the preparation of the Final Report of the Board to the Commission. The Board has developed a critical path diagram to assist in the control of the various interrelated portions of the study. This diagram will be updated to reflect changes in conduct of the studies and work schedule. A detailed briefing on the methodologies and progress of the Study was given by study participants to the Commission in December 1969. The Levels Board studies are being coordinated with the Provinces and States which border on the Great Lakes and their outflow rivers. Personnel of the appropriate Provincial and State Agencies are cooperating with those of the participating Federal Agencies. 2J. COORDINATING COMMITTEE ON GREAT LAKES BASIC HYDRAULIC AND HYDROLOGIC DATA. Constitution and duties. The Committee was formed on May 7, 1953 for the purpose of establishing a basis for development and acceptance by both countries (United States and Canada) of identical hydraulic and hydrologic data for the Great Lakes and their outflow 1287 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 channels. The Committee was established advisory to the agencies of the United States and Canada which are charged with the responsibility for collecting and compiling the Great Lakes hydraulic and hydrologic data. Three working subcommittees, designated the River Flow Subcommittee, the Vertical Control Subcommittee and the Lake Level Subcommittee were formed to assist the Coordinating Committee in its work. Subsequently, a fourth subcommittee, designed the Physical Data Subcommittee, was formed. These subcommittees were directed to conduct the required technical studies through collaboration of the appropriate agencies of the United States and Canada. Members of the Committee for fiscal year. The United States members were Mr. H. F. Lawhead, Acting Chief, Engineering Division, U. S. Army Engineer, Division, North Central, Chairman, U. S. Section, Mr. B. G. DeCooke, Assistant Chief, Engineering Division, U. S. Army Engineer District, Detroit, and Mr. F. A. Blust, Chief, Engineering Division, Lake Survey Center, National Ocean Survey, Department of Commerce. Members for Canada were Dr. A. T. Prince, Director, Inland Waters Branch, Department of Energy, Mines and Resources, Chariman, Canadian Section, Mr. D. M. Ripley, Director, Marine Hydraulics Branch, Department of Transport and Mr. D. F. Witherspoon, Great Lakes St. Lawrence Study Office, Department of Energy, Mines and Resources. Operations during fiscal year. The Coordinating Committee held two meeting during the fiscal year; the first meeting took place in Niagara Falls, Ontario on September 17, 1969; the second meeting was held in Ottawa, Ontario on June 17,1970. The River Flow Subcommittee completed the work on Lake Superior outflow report. A study of rating of the compensating works in the St. Marys River was started, and the study of St. Clair River flows was continued. The Vertical Control and Lake Level Subcommittees completed a first draft of a report on Lake Erie water level gage histories. Work was continued on preparation of gage histories for Lake Michigan- Huron and the Straits of Mackinac. Leveling for the updating of IGLD (1955) was continued between Fort Niagara and Sturgeon Pt. Operation of seasonal gages for the Lake Ontario hydrostatic leveling study and for crustal movement studies was continued. The Physical Data Subcommittee completed coordination work of water surface and land areas of the Niagara River Basin. Work was continued on the determination of Lake Huron and Lake Superior water volume. 2K. INTERNATIONAL GREAT LAKES STUDY GROUP Constitution and duties. The International Great Lakes Study Group is an informal organization including representatives of Canadian and U. S. agencies and institutions engaged in basic and applied research, and engineering investigations related to the development and utilization of the Great Lakes water resources. The Group was formed October 1962 as the Lake Erie Study Group and was later renamed the Great Lakes Study Group in recognition of the members interest in all the Great Lakes and its primary purpose is to facilitate the exchange of information and to provide informal coordination among the various research activities relating to the Lakes. The Group provides a forum for assisting,. coordinating and eliminating duplication. It also sponsors a data repository for the cataloging, storage and circulation of basic data. Members of the Group for fiscal year. The Steering Committee of the Study Group consists of up to six members from each country, including a Co-Chairman, an Alternate Co-Chairman and a Secretary.

INTERNATIONAL LAKE SUPERIOR BOARD OF CONTROL Constitution and duties. The Board, established in pursuance of orders issued by the International Joint Commission May 26 and 27, 1914 is charged with the supervision of the operations of all compensating works and all power canals and appurtenances with a view to so controlling the outflow from Lake Superior as to maintain its level as nearly as may be between elevations 600.5 and 602.0 feet above mean water level at Father Point, Quebec (International Great Lakes Datum- 1955) and to so control the outflow as to prevent the level of the St. Marys River below the locks from exceeding elevation 582.9 Members of the Board for fiscal year. Mr. R. H. Clark, Special Advisor to the Director, Inland Waters Branch, Department of Energy, Mines and Resources was the member of the Board for Canada. The Division Engineer, U. S. Army Engineer Division, North Central was the United States member, ex-officio. Brigadier General W. W. Watkin, Jr. was North Central Division Engineer, during the fiscal year. Operations during fiscal year. The Board kept in touch during the year with conditions pertaining to the regulation of Lake Superior through representatives of Canada and the United States on the ground and by means of regular and systematic reports of the water levels on Lake Superior, in the St. Marys River above and below the Sault Locks, and on Lake Huron. Records of discharge at Sault Ste. Marie through the rapids, navigation canals and power plants were also systematically reported to the Board. Change in the rate of outflow from Lake Superior are directed by the Board as indicated by the rule curve currently in use. During the past year the Board has continued the use of the modified plan of operation under the Rule of 1949 for the regulation of Lake Superior. During September through December 1969 the Lake Superior Board withheld about 38,000 cfs-months of water in Lake Superior, in relation to the outflow requirements of the current plan of regulation in order to compensate for the additional water which would be discharged later from the lake in carrying out a winter test program. The winter test operations were conducted at the Sault Ste.Marie control works in the St. Marys River, as part of the study being carried out by the International Great Lake Levels Board. The Board's Working Committee is determining the feasibility of discharging successfully 95,000 cfs under a greater variety of winter conditions than those which prevailed during the 1968-69 winter season. The winter tests have been carried out satisfactorily and no problems have arisen with regard to the winter operation of the gates or with any ice jamming on the lower St. Marys River under the increased flows. Detailed arrangements were made for continuous monitoring of the water levels in the lower St. Marys River so that at the first sign of any impending ice build-up, immediate preventive action would be taken by closing the required number of gates. Approval from the Great Lakes Power Corporation, which owns the Canadian portion of the control structure, was obtained for the operation of these gates for the winter test program. In accordance with the Board's instructions to the on-site representatives, the opening of the gates .commenced on February 9 and was successfully completed on February 11 despite very heavy ice conditions. During the ensuing weeks, continuous hydraulic monitoring and visual inspections of the river showed that it was again carrying the higher flow without difficulty. By the end of February it was apparent that river conditions were stable, with little likelihood of ice jams developing, and that little useful experience would be gained by prolonging the test period. The Board approved the recommendation of the Working Committee to discontinue the tests and return to the normal winter outflow. This operation was successfully carried out as a simulated emergency test without giving prior warning to the gate operating crew. This premature termination of the test has left approximately 20,000 cfs months of water in storage. Levels Board Working Committee plans to continue the winter tests during the 1970 - 71 winter season. In preparation for these tests, the Board has noted the request from the Committee that operations to store water be continued. In this regard, the Board authorized storage of about 13,000 cfs months during June 1970. During its June 13, 1968 inspection of the Compensating Works in the St. Marys River, the Board noted that no work had been done to repair the noses of the piers in the Canadian portion of the Works. Becuase of high water in the lake during 1968 and the possibility of high water last year, the necessary pier maintenance was deferred. On the basis of reduced water supplies and consequent normal water levels, the Board decided to proceed with the necessary repairs. The Board has initiated a contract this summer for urgent repairs to these piers. Several letters written on behalf of property owners on the United States side of the lake, were received by the U. S. Members of the Board concerning high water conditions on the lake during the fiscal year. Appropriate replies were communicated in each case. No similar correspondence has been received by the Canadian Member of the Board. 2M. INTERNATIONAL PRAIRIE PORTAGE BOARD OF CONTROL Constitution and duties. The International Prairie Portage Board of Control was formed by International 1289 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1970 Joint Commission for purpose of furnishing it with technical advice regarding suitability of dam structure at Prairie Portage, Lake County, Minn. After approval of plans by Department of the Army and International Joint Commission, the Board was retained to advise the Commission further regarding progress of construction and any other matters which might arise concerning this project. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, 1Iines and Resources, represented Canada, and Col. Charles I. McGinnis, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. The U. S. Forest Service constructed a cofferdam before World War II but postponed work on the project during the war. On June 12, 1968 after a period of heavy rains the cofferdam was washed out, resulting in lowering the lake levels of Birch, Sucker, Moose, Newfound and Ensign Lakes. This caused considerable difficulty for boating, as shallow water exists at the outlet of the lakes. By November 10, 1968 the U. S. Forest Service completed reconstruction of the Prairie Portage cofferdam which has been functioning satisfactorily at the control dam for the lakes. The reservoir was refilled by December 25, 1968. The U. S. Forest Service recently revised the design of the proposed permanent dam which is expected to be submitted to the Board for approval. A special request was sent to the Bureau of Budget by the U. S. Forest Service for construction funds for starting the Prairie Portage Dam in fiscal year 1971. However, funds may not become available until fiscal year 1972. 2N. INTERNATIONAL RAINY LAKE BOARD OF CONTROL Constitution and duties. The Convention between the United States and Canada, ratified by U. S. Senate August 30, 1940, provides in part that: "The International Joint Commission ... hereby clothed with power to determine when emergency conditions exist in the Rainy Lake watershed, in the event the Commission shall determine that such emergency conditions exist." On June 8, 1949, the Commission issued an order to the owners of dams at outlets of Namakan Lake and Rainy Lake, which provide for a method of regulation as recommended by International Rainy Lake Board of Control. The order provides for certain levels during the various seasons of the year as well as control of outflows, with view to securing most advantageous use of water in total to the various interests. A supplementary order dated October 1, 1957 modified regulations for Namakan Lake to provide for some variation in operation based on anticipated spring runoff. This supplementary order was extended to October 1967 and again to October 1972, by action of the International Joint Commission on October 2, 1962 and April 5,1967, respectively. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, represented Canada, and Col. Charles I. McGinnis, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. Studies the past year by the Control Board have resulted in proposed revision of the Orders of Approval rule curves. The International Rainy Lake Board of Control met with the International Joint Commission in Ottawa in October 1969 and again in April 1970 in Washington, D. C. to discuss proposed orders and rule curves. The International Joint Commission is presently drafting the final orders which are expected to be completed shortly. The members of the Board and their staffs met with resort and other property owners on April 13, 1970 at International Falls to discuss existing and forecast levels of the Rainy and Namakan Chain of Lakes. Due to above normal rains in May and June 1970, Namakan Dam was opened wide by 10 June and Rainy Dam by 1 June. Both continued discharging the maximum possible to the end of the fiscal year. 20. INTERNATIONAL LAKE OF THE WOODS CONTROL BOARD Constitution and duties. 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 Government of Canada to establish and maintain a Canadian Lake of the Woods Control Board to regulate and control outflow of waters of the lake, and for establishment and maintenance of an International Lake of the Woods Control Board, composed of two engineers, one representing the United States and the other representing Canada, to whose approval the rate of total discharge shall be subject whenever the water level rises about elevation 1061 or falls below elevation 1056, sea level datum. Members of the Board for fiscal year. Mr.J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, represented Canada and Colonel Charles I. McGinnis, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscalyear. Maintained supervision to insure that every effort was being made to comply with the provisions of the Convention. One engineer of Colonel McGinnis' staff attended the September 16, 1969 meeting of the Canadian Lake of the Woods Control Board in Winnipeg. On April 14, 1970, the St. Paul Deputy District Engineer and one staff engineer 1290 MISCELLANEOUS CIVIL WORKS attended an open meeting with local interests at Warroad, Minnesota, sponsored by the International Lake of the Woods Control Board to discuss levels on Lake of the Woods. Two engineers of Colonel McGinnis' staff attended a meeting on June 17, 1970 on the Lake of the Woods Control Board in Winnipeg. All the above meetings were cooperative efforts of both the Canadian and the American members of the Control Board in arriving at the best solutions to the operating problems. Above normal rainfall in May and June 1970 resulted in heavy runoff. Elevation 1061 was exceeded on 12 June at which time responsibility for the operation of Lake of the Woods was assumed by the International Lake of the Woods Control Board. The outflow from Lake of the Woods was actually increased to the maximum on June 3, 1970 and continued to the end of fiscal year 1970. 2P. INTERNATIONAL PEMBINA RIVER ENGINEERING BOARD Constitution and duties.
