Local interests are required to repay all the costs allocated to water supply, as determined by the Chief of Engineers, in accordance with the provisions of the Water Supply Act of 1958, as amended, presently estimated at $5,210,000 exclusive of interest; pay or repay one-half separable first costs allocated to recreation and fish and wildlife presently estimated at $80,000, and administer, operate and maintain, including replacement, recreation and fish and wildlife lands and facilities, all in accordance with the Federal Water Project Recreation Act; protect channels downstream of the reservoirs from encroachments which would adversely affect operation of the system; at least annually notify interests affected that project will.not provide complete flood protection; hold and save the United States free from all damages due to water rights claims resulting from construction and operation; and exercise to the full extent of their legal capability, control against removal of streamflow made available by reservoir storage for low-flow augmentation. Estimated cost to local interests is $5,290,000. Formal assurances will be requested during final design. Operations and results during fiscal year. Advance engineering and design was continued. Condiition at end of fiscal .- ear. New Vork: Advance engineering and design is 70 percent complete. 68. INSPECTION OF COMPLETED FLOOD CONTROL PROJECTS In accordance with provisions of Flood Control Act of 1936, as amended, local flood protection works constructed with Federal funds are transferred to local interests to operate and maintain. To insure compliance with regulations prescribed for their operation and maintenance regular inspections of the following projects were made during the fiscal year: Connecticut. November 1970 and June 1971-East Branch Dam, Hall Meadow Brook Dam, Mad River Lake, Norwalk, Torrington, Stamford, Waterbury-Watertown and Wiinsted; December 1970 and June 1971-Norwich, Pawcatuck; December 1970 and June 1971-East Hartford, Hartford.

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, to flood control releases, water supply and flow augmentation releases were made from selected reservoirs. Regulation of an appreciable nature during the fiscal year was as follows: Blackstone River Basin. The West Hill reservoir was regulated in March 1971, resulting in 4 percent of storage being utilized. Connecticut River Basin. During the month of April 1971, Ball Mountain, Townshend, Surry Mountain, Otter Brook, Birch Hill, Tully and Littleville reservoirs utilized storage ranging from 5 to 11 percent. In May 1971, Union Village, North Hartland, North Springfield, Ball Mountain, Townshend, and Surry Mountain were regulated with 5 to 13 percent of flood control storage utilized. In addition releases for white water canoeing occurred at Ball Mountain during October 1970 and May 1971. Water supply and fishing releases were discharged from Colebrook River Reservoir. Ihousatonlic Ri'er Basin. Hop Brook was regulated in March 1971 utilizing 6 percent of storage. During 1 - 46" NEW ENGLAND DIVISION April 1971, Hall Meadow utilized storage to 5 percent. In May 1971, Thomaston stored 4 percent. Merrimack River Basin. In July 1969 Franklin Falls, Hopkinton and MacDowell were operated utilizing flood storage of 4, 8 and 18 percent respectively. In May 1971 Franklin Falls stored 9 percent, Hopkinton 5 percent, and Blackwater 3 percent. Thames River Basin. There were no significant flood control operations at any of the six reservoirs during the fiscal year. Releases were made from East Brimfield during the summer months to augment low flows. 70. 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 15 occasions, all due to coastal storms. The maximum ocean tide rose to 7.2 feet msl. New Bedford-Fairhaven Barrier. The barrier gates were closed on 7 occasions, all due to coastal storms. The maximum ocean tide rose to 5.3 feet msl. Fox Point and Pawcatuck Barriers. Neither of these barriers were operated during the fiscal year. 71. OTHER AUTHORIZED FLOOD CONTROL PROJECTS (See Table 1-N at end of chapter.) 72. FLOOD CONTROL WORK UNDER SPECIAL AUTHORIZATION Flood control activities pursuant to section 205, Public Law 858, 80th Congress, as amended (preauthorization) (See table at end of chapter.) Snagging and Clearing activities pursuant to section 208, Public Law 780, 83rd Congress Stoney Brook, Wilton N.H. Costs for fiscal year were $4,921. Emegency flood control activities-repairf,l oodf ighting, and rescue zwork (Public Law 99, 84th Cong., and antecedent legislation) Federal costs for fiscal year were $66,817 for advance preparation of flood control and coastal emergencies, $233,372 for emergency operations and $216,960 for rehabilitation work on the Blackstone River at Blackstone, Mass. GENERAL INVESTIGATIONS 73. SURVEYS Fiscal year costs for surveys from regular funds were $498,084 of which $198,963 was for navigation surveys; $242,953 for flood control surveys; $30,423 for beach erosion surveys; $44,005 for coordination surveys; and $25,745 for comprehensive basin surveys. 74. COLLECTION AND STUDY OF BASIC DATA The I)ivision Engineer is the U.S. representative on Saint John and Saint Croix River Engineering Committee. He is also U.S. member on Saint Croix River Board of Control. Annual inspections are made of conditions on these two rivers and a continuing program of compilation of basic hydrologic information is carried out. Division Engineer's representatives during past year kept closely in touch with developments in the two basins and cooperated with their Canadian counterparts assisting in development of basins' resources. Total costs for fiscal year were $2,344. Total costs to June 30, 1971 were $22,993. Flood plain studies comprise compilation and dissemination, upon responsible local request, of information on floods and potential flood damages, including identification of areas subject to inundation by floods of various magnitudes and frequencies, and general criteria for guidance in use of flood plain areas; and engineering advice to local interests for their use in planning to ameliorate flood hazard. Total costs for fiscal year were $304,883. Total costs to June 30, 1971, were $1,184,546.

SUPERVISION OF NEW YORK HARBOR (Prevention of Obstructive and Injurious Deposits) The District Engineer, New York District, was designated Supervisor of New York Harbor by the River and Harbor Act of June 29, 1888 (33 U.S.C. 441-451), as amended July 12, 1952. Under this act, the Supervisor of New York Harbor is charged with the mission of preventing the deposit of obstructive and injurious materials in New York Harbor and its adjacent and tributary waters, including Long Island Sound. The Supervisor of New York Harbor is also responsible for enforcing River and Harbor Act of August 18, 1894 (33 U.S.C. 452) which makes it unlawful for any person or persons to engage in fishing or dredging for shellfish in any of the channels leading to and from New York Harbor, or to interfere in any way with the safe navigation of those channels by ocean steamships and ships of deep draft. River and Harbor Act of March 3, 1899 (33 U.S.C. 403, 407,409), commonly known as the Refuse Act, applies to all navigable waters of the United States. This statute is used for enforcement purposes by the New York District Engineer on waterway violations not within the scope of the act of 1888 or on violations that occur within his area of jurisdiction outside of New York Harbor and Long Island Sound. 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, Harlem River and Long Island Sound. Enforcement of the act of 1888 in Long Island Sound is limited to the Sound itself, ending at lines drawn between the headlands of the many inlets and harbors along its shores. The Supervisor of the Harbor, in his capacity as District Engineer, may apprehend violators of antipollution laws under authority of the Act of March 3, 1899 when violations occur in the inland tributary waters of Long Island Sound. The navigable waters of the Hudson River extending north from Troy, New York to New York District boundary line at the Canadian border are under the jurisdiction of the District Engineer. Patrol boats are used to accomplish inspections of waterways. One boat operates in Lower New York Bay and another in Long Island Sound to ensure that vessels deposit dredged or other types of waste material in the dumping areas specified in permits issued 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 Upper New York Bay and the inner waters, such as Hudson River, East River, Kill Van Kull, Arthur Kill, Passaic and Hackensack Rivers, to prevent the illegal deposit of cellar dirt, ashes, industrial waste or any other refuse into the navigable waters or on the beach or shore areas where it may be subject to tidal action. Inspections of shorefront facilities are conducted by inspectors utilizing Government vehicles equipped with two-way radios to ensure that industrial waste or refuse is not being discharged or deposited into the navigable waters. These inspectors operate out of various field offices located at Jersey City, New Jersey, Fort Totten in Bayside, New York, Fort Tilden at Rockaway, New York, and offices in Kingston and Troy, New York.

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, located 158 feet east of former bridge. 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; a clear and unobstructed channel 500 feet wide. Notice to alter existing bridge was signed by Secretary of the Army on July 5, 1949. Estimated Federal share of cost of new work is $7,995,000 (July 1969). Estimated cost to local interests is $1,635,000. (See Table 2-B for Authorizing Legislation.) Local cooperation. Fully complied with. Operation and results during fiscalyear. Remaining funds revoked. Condition at end of fiscal year. 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. Settlement of claims remains. BEACH EROSION CONTROL 34. FIRE ISLAND INLET, LONG ISLAND, N.Y. Location. Atlantic Coast of Long Island, N.Y., between Fire Island Inlet and Jbnes 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 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 $22,546,767 (July 1971), of which $2,646,767 is for work authorized by 1958 River and Harbor Act, and $19,900,000 for modification authorized by 1962 River and Harbor Act. Project documents contain latest published maps. (See Table 2-B for Authorizing Legislation.) 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 2 - 20 NEW YORK, N. Y., DISTRICT 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, was 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 are a non-Federal responsibility. Total estimated cost of local cooperation to be provided by local interests is $15,272,835 (July 1971) for new work, of which $2,272,835 (cash contribution) is for work authorized by the 1958 act; and $13,000,000 the 1962 act, of which $12,980,000 is cash contribution and $20,000 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. Using appropriations for planning of work authorized by the 1962 Act, advance engineering and design continued. Draft Design Memorandum was submitted to the Office of the Chief of Engineers September 28, 1971, and approved subject to comments on February 12, 1971. Comments were submitted April 14, 1971. Advance plans and specifications were submitted April 15, 1971. The Environmental Statement was submitted to the Council of Environmental Quality on April 16, 1971. Coordination was continued with representatives of Federal agencies and State and Suffolk County officials. 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 90 percent complete. Model test by Waterways Experiment Station was completed and report submitted November 1969. 35. OTHER AUTHORIZED BEACH EROSION CONTROL PROJECTS (See Table 2-I at end of chapter.) 36.

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 Wallomsac 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. Previously "inactive" due to limited support by local interests for construction, the project was reclassified to "deferred for restudy"January 18, 1965, based on the reported gradual erosion of left bank of Roaring Branch which local interests considered a serious threat of flooding. Resulting from the "restudy" (feasibility study report) started December 1965 and completed March 1966, the portion of the project on the left bank of the Roaring Branch, generally between Branch and Park Streets, was reclassified from "deferred" to "active" on May 27, 1966. The im- 2 - 21 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 provement provides for constructing 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 1971), 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. (See Table 2-B for Authorizing Legislation.) 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 30 April 1970. Operations and results during fiscal year. Five Point Environmental Statement was submitted to North Atlantic Division July 1970. Construction continued. Condition at end of fiscal year. Continuing contract was awarded May 27, 1970. Construction was started and about 80 percent complete. 38. 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 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 (50 percent) in cost of periodic beach nourishment of the shore protection works for 10 years after completion of the initial beach fill. Estimated Federal cost is $45,925,000 for construction (which represents 68 percent of total first cost of project reduced by amount of local cash contribution presently estimated at $5,020,000 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 $335,000 annually for periodic nourishment for 10 years, a total of $51,280,000 (July 1971). Maintenance, operation and major replacements of the barrier, its gates and fishing platforms would be a Federal responsibility. Estimated non-Federal cost is $29,930,000 (representing 32 percent of total first cost of project) consisting of $180,000 for lands and alterations and relocations of structures, and a cash contribution of $29,750,000; an additional cash contribution of $5,020,000 for the barrier, its gates and fishing platforms; and $455,000 annually for periodic nourishment for first 10-year period; a total of $34,480,000 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.

That portion of Atlantic Coast of Long Island in Suffolk County extending from Fire Island Inlet easterly to Montauk Point, N.Y. - about 83 miles long. This frontage, 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 by: widening beaches along developed areas between Kismet and Mecox Bay to a minimum width 2 - 23 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 $46,500,000 (July 1971) which includes participation in periodic beach nourishment for 10 years at $48,000 annually. Total estimated non-Federal cost for all requirements of local cooperation is $46,600,000 (July 1971), inclusive of $38,240,000 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 one-half of costs allocated to beach erosion control feature, in lieu of one-third authorized by Public Law 727, 79th Congress. Evaluation increased Federal participation from about 51 percent to about 53 percent of first cost of project construction, excluding annual nourishment costs. 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 $41,440,000, to consist of items listed in (a) and (b) above and a cash contribution estimated at $38,240,000, 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 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 $48,000 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 2 - 24 NEW YORK, N. Y., DISTRICT 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. The completed 2 groins and 11 groins were accepted by the New York State Department of Public Works for maintenance on May 11, 1966 and April 10, 1967, respectively. On March 22, 1965, the State 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; meeting with Congressional representatives, State legislators, Federal agencies and local officials held on May 26, 1966; and 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 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 was accepted by the District Engineer on January 24, 1969. This reaffirmed previous assurances contained provisions for constructing four additional groins in an area extending 6,000 feet west from the most westerly groin in the existing eleven-groin field in the Moriches Inlet to Shinnecock Inlet Reach, and for placing beach and dune fill in this 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 this stage construction established 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 required that the State obtain and provide without cost to the United States all lands, easements, and rights-of-way, to permit entry 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. (See Table 2-B for Authorizing Legislation.) Operations and results during fiscal year. Coordination with State and local interests continued. Design in Reach "2 for six groins and placement of dunes and beachfill extending westward about 9,000 feet from the present :Westhampton Beach construction site was delayed pending resolution of the revised cost sharing authorized by the 1970 Flood Control Act. On the third contract (Westhampton Area) four groins and dune and beachfill were completed November 1970. 3,083 tons of stone and 1,111,000 cubic yards of sand were placed. Costs for new work were $70,983 for engineering and design, and $461,187 for construction. Condition at end of fiscal year. Engineering and design began November 1962 and is about 57 percent complete. Project construction commenced January 18, 1965 and is about 7 percent complete. Two groins in Reach 4: Southampton-Beach Hampton, Section 3, were initiated in March, and completed in September 1965, at a total cost of $592,418 of which $439,000 were incurred against required contributed funds. Eleven groins in Reach 2: Moriches-Shinnecock, Section 2, were initiated in January 1965, and completed in October 1966 at a total cost of $2,854,565 of which $1,370,191 were incurred against required contributed funds. Initial beach fill placement for 750,000 cubic yards in Reach 2, Section 1A was completed on May 23, 1969. On August 4, 1969 work started on 4 groins and sandfill in Reach 2, Section 1A and was completed November 14, 1970. Total cost for all Section 1A was $3,212,211 including $1,570,771 required contributed funds. Completion of engineering and design, and construction of the remainder of the project remain. 41.

Terminal facilities. The Port of Baltimore has 45 miles of waterfront of which 25 miles are industrially developed. There are 94 covered and open overseas piers for the loading and discharging of 173 ships, providing 84 general cargo, 65 specialized cargo, and 24 public bulk cargo berths. The existing ground storage is equivalent to 53,700 railroad cars of cargo. There are 31 public general merchandise warehouses, with 4.9 million square feet of storage space and 4.7 million cubic feet of cold storage space. Eight shipbuilding, ship repair, and ship dismantling yards are available for handling up to 90 vessels. The three grain elevators in the port have a capacity of about 13 million bushels. Latest description of terminal facilities is in "Port Series No. 10 (revised 1966)" on Port of Baltimore, Md., issued by Board of Engineers for Rivers and Harbors.

For description of District of Columbia water supply system and of previous capital-improvement and 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, toJune 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, 4 - 27 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 expenses of operation and maintenance have been paid wholly out of water revenues of the District of Columbia. From April 1953, to June 30, 1971, $31,000,000 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 fiscalyear. 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.

Average per capita daily consumption was 183.8 gallons. Average daily amount of water furnished to Arlington County, Fairfax County, and Falls Church, Va., was 38.3 million gallons, an average per capita daily consumption of 118 gallons. The Water Fund, D. C., was reimbursed $1,576,845 for supply of water furnished Virginia communities. An average of 157,000 gallons per day was delivered to Maryland communities during fiscal year 1971 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 0.31 parts per million or "Jackson Units." Analyses were made for coliform bacteria on 131,929 tubes of Lactose broth inoculated with water taken from 208 sampling points in the collection, purification, and distribution systems. Approximately 81,896 physical and chemical tests were made on 13,661 water samples from the supply and distribution system. After sterilazation of the filter effluent, average Most Probable Number of coliform bacteria per 100 milliliters was found to be .10 at Dalecarlia and .07 at the McMillian Water Plant. Average calcium carbonate alkalinity of the filtered water was 63 P.P.M. and the average pH value was 7.8 from Dalecarlia Water Plant, and 61 and 7.8 respectively, from McMillan Water Plant. Average hardness was 123 P.P.M. from Dalecarlia and 121 P.P.M. from McMillan. Flourine content of 4,268 water samples was determined. In fiscal year 1971, direct operating cost of water treated and delivered to system per million gallons was $56.60 as compared with cost of $56.80 per million gallons in fiscal year 1970. Visitors. During the year 786 persons were conducted through water treatment and pumping plants and bacteriological and chemical laboratories of which 771 were engineering and science students, public school pupils, civic groups, and public officials, 15 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 4 - 28 BALTIMORE, MD., DISTRICT 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, 96 percent; repairs to roadways and landscaping, 60 percent; new shops and storehouses, Dalecarlia, 30 percent; Great Falls intake structure, 99 percent; flood and water quality protection Dalecarlia 85 percent. Funds are being requested in the fiscal year 1972 budget for planning of water treatment plant extensions and improvements at Dalecarlia and McMillan; for beginning construction of rapid-mix and baffle facilities at Dalecarlia, and for the completion of construction of the shops and storehouses at Dalecarlia. Congress approved, in the First Supplemental Appropriation for fiscal year 1971, $1,140,000 for emergency pumping from the Potomac River Estuary. 4 - 29 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 TABLE 4-A COST AND FINANCIAL STATEMENT See Section Total to in Text Project Funding FY68 FY69 FY70 FY71 June 30, 1971 Injurious Deposits 10.

This provides for a channel 80 feet wide and 12 feet deep from the mouth of the river to a * 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. 5-1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 point 400 feet above Lieutenant Run; thence 80 feet wide and of such depth, not exceeding 12 feet, as can be obtained without rock excavation to the head of navigation at Petersburg; including a basin at the mouth of Poes Run 200 feet long, 150 feet wide, and 20 feet deep: and a turning basin at the mouth of Lieutenant Run 500 feet long, 140 to 160 feet wide, and 12 feet deep in the upper 300 feet, the removal of rock to a depth of 18 feet in the north half of the lower 200 feet, and removal of soft material to rock in the south half of the lower 200 feet of this basin. All depths are referred to mean low water. The project also provides for a dam at Petersburg and the excavation for a width of from 200 to 300 feet of a diversion channel connecting the river above the dam with the river at a point 2.5 miles below; for about 1.7 miles of levees on the low grounds between the navigable and the diversion channels; for a highway bridge and a railway bridge across the diversion channel; and for other work incidental to the diversion channel. Under ordinary conditions the mean tidal range is 2.9 feet and the extremes 2.4 and 3.3 feet. There are no records available of the heights of stage due to ordinary floods. These are estimated at 6 to 8 feet above mean low water at Petersburg, where the extremes are from 15.6 feet to 17.1 feet. (See Table 5-B for Authorizing Legislation.) Local cooperation. Fully complied with. For details see page 212 of Annual Report for 1969. Terminal Facilities. There are about 2,500 feet of wooden bulkhead and a shore landing in Petersburg Harbor. These facilities are in an abandoned, dilapidated condition and have not been used by commercial traffic on the river since 1950. There are two large recreational facilities now in operation on the Appomattox River. One is located about 2 miles downstream from Petersburg, Virginia and the other is at Hopewell, Virginia near the confluence of the Appomattox and the James. Operations and results during fiscal year. Condition surveys were accomplished and the economics of the project reviewed. Authority and funding were received for maintenance dredging to permit recreational use of the project downstream of mile 8.5. Plans and specifications were prepared and a contract awarded at the end of the fiscal year. Condition at end of fiscal year. The existing project has been partially completed as follows. Construction of the diversion channel and other work incidental thereto was commenced in 1904 and continued intermittently to October 1921 when the work was completed. Construction of the channel 80 feet wide and 10 feet deep at mean low water was commenced in September 1929 and continued intermittently to January 1931 when the work was completed. The work remaining to complete the project consists of providing a channel 12 feet deep and generally 80 feet wide from the mouth of the river to the lower end of the turning basin at Lieutenant Run; a channel 80 feet wide and of such depth, not exceeding 12 feet, as can be obtained without rock excavation from the upper end of the turning basin to the head of the existing project; extending the existing turning basin to a point 100 feet below the center line of Lieutenant Run; widening this basin to 160 feet at the bend at the mouth of the run and to .140 feet at the lower end; removing all rock lying less than 18 feet below mean low water in the north half of the lower 200 feet of the basin; removing soft material in the south half of the lower 200 feet of this basin to rock; dredging the remainder of the turning basin to a depth of 12 feet; and dredging a basin 20 feet deep, 150 feet wide, and 200 feet long at the mouth of Poes Run. Depths are referred to mean low water. The uncompleted portion of the project is considered inactive. The project is shoaled above mile 9.5 to the extent that navigation is not possible. Shoaled conditions exist, to a lesser extent, on the remainder of the project. The maintenance dredging, under contract at the close of the fiscal year, will restore a 6-foot deep by 60 feet wide passage below mile 8.5. The total cost of the existing project to June 30, 1971, was $1,448,173 of which $847,841 was for new work including $260,000 for the diversion channel and $600,332 for maintenance. 2.

Permanent operating equipment, to be used on both routes, was purchased at a direct cost of $11,768. Spare parts for Great Bridge lock gates were purchased at a cost of $7,674. Maintenance snagging and bank trimming operations, with Government plant and hired labor, were carried on at several locations on both routes intermittently at a direct cost of $10,784. Maintenance repairs to bulkheads on both routes, with Government plant and hired labor, were accomplished at a direct cost of $10,246. Maintenance engineering and design, supervision and administration and real estate activity costs, less credits for collections for quarters and damages to Government property, amounted to $54,725. Condition at end of fiscal year. Project is complete. For construction details, see Annual Report for 1966. Total cost of existing project to June 30, 1971, was $24,154,687 of which $3,396,276 (including $1 million for purchase of Albemarle & Chesapeake Canal and Dismal Swamp Canal) was for new work, $20,278,464 for maintenance, and $479,947 for rehabilitation Periodic maintenance dredging is being done maintain full project dimensions on the Albemarle and Chesapeake Canal Route and about a 7-foot usable depth on the Dismal Swamp Canal Route which is considered adequate for existing traffic. 3. 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 have been received. As a result of coordination meetings and correspondence, interest was indicated such that a one season, 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 plant problems exist. This reluctance was due primarily to the lack of an acceptable method of control. Surveillance of the aquatic plant infestations in these areas is continuing. Condition at end of fiscal year. The General Design Memorandum has been approved and a one season, experimental treatment authorized for the Walker Dam Irpoundment, Chickahominy River, Virginia. The Virginia Commission of Game and Inland Fisheries has tentatively agreed to furnish the items of local cooperation required for the one season experimental treatment. Pending receipt of the formal 5-3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 assurances of local cooperation, spraying operations are scheduled in late fiscal year 1972. 4.

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. Treatment of 250 acres of Eurasian watermilfoil in three separate high priority high use areas, using granular 2,4-D applied by helicopter, was performed in June 1971. Sites of work were in the Currituck Sound area (Point Harbor, Martins Point Creek, and Alligator Creek). Excellent results were obtained. Treatment of 150-200 acres alligatorweed continued in several areas ranging from Wilmington, N. C., to near Elizabeth City, N. C. This weed, in most treatment areas, is essentially under control. The work was accomplished at a Federal cost of $11,189 and contributed costs of $6,629. Condition at end offiscalyear. The State General Design Memorandum was submitted to higher authority and approved December 1969. The supplemental agreement to contract with the State of North Carolina was approved and accepted by the State, effective April 1970. 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.

Estimated Federal Cost is $13,700,000. Plane of reference is mean low water. In the waterway north of Neuse River, variations in water surface due to winds seldom exceed 2 feet above or below mean stage. Between Beaufort and the Cape Fear River, normal tidal range varies from 3.5 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 3.5 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. C., mean tidal range varies between 4.7 feet in Cape Fear River and 4 feet at the intermediate inlets, and 2 feet at points midway between the inlets. On October 15, 1954 (Hurricane Hazel), the tide at Holden Beach reached an elevation of 17.6 feet. (See Table 6-B for authorizing legislation.) Local cooperation. Fully complied with to date except for the modificaiton. The State of North Carolina has agreed to pay 25 percent of the total project cost presently estimated at $4,600,000.

The project is located in Charleston County, on the southeastern end of Wadmalaw Island near the village of Rockville. The estuarial creek flows generally southward into Bohicket Creek and from there into the North Edisto River and then into the Atlantic Ocean. Existing project. The project provides for a stable alltide channel 10 feet deep and 80 feet wide extending from that depth in Bohicket Creek to a turning basin in the vicinity of the uppermost dock at Rockville, a distance of 1.45 miles. The channel would be dredged to a 2-foot overdepth and would assume side slopes of around 4 horizontal to 1 vertical, and would follow the general alignment of the natural channel. (See Table at End of Chapter for Acts Authorizing Existing Project.) * All cost and financial statements for projects are listed at the appear at the end of this chapter. Operations and results during fiscal year. Preconstruction planning continued during the year. Local cooperation was temporarily withdrawn because of objections to location of proposed spoil area. Local interests attempted to locate an acceptable alternate disposal area and obtain easement from State, but this was not completed during the year. Condition at end of fiscal year. Construction has not been initiated. 2. AQUATIC PLANT CONTROL, N.C. AND S.C. Location. The project areas cover navigable waters, tributary streams, connecting channels, and other allied waters.in the Charleston District. Existing project. The project provides for control and progressive eradication of water-hyacinth, alligatorweed, Eurasian watermilfoil and other obend of this chapter. All other tables are referenced in text and also 7-1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 noxious aquatic plant growths from navigable waters, 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 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 and North Fork Edisto River. Colonies of Flea Beetles (Agasicles) were established for biological control of alligatorweed at Foster Creek near Charleston, at O'Neil's Lake near Fairfax, at Mulberry Plantation in Berkeley County, at Halfway Swamp on Lake Marion, the upper Santee Basin near Starr, and in the Edisto and Ashepoo River basins. Inspection of the release sites revealed very little activity through August, but significant enlargment of beetle colonies and increased attack on alligatorweed occurred in September and October. Condition at end of fiscal year. Chemical spraying operations have been conducted on approximately 1,000 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. 3. ATLANTIC INTRACOASTAL WATERWAY BETWEEN NORFOLK, VA., AND ST. JOHNS RIVER, FLA. (CHARLESTON DISTRICT) Location. The project starts on Little River near the North Carolina-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. (See U.S. Coast and Geodetic Survey Charts Nos. 835,836 and 838.) Previous projects. For further details see page 613 of Annual Report for 1932. Existing project. The project provides for a waterway 12 feet deep and not less than 90 feet wide with a branch channel of the same dimensions to McClellanville, and construction of three bridges crossing the waterway in Horry County, South Carolina. (See Table at End of Chapter for Acts Authorizing Existing Project.) Local cooperation. Fully complied with. Terminal facilities. There are rail-water terminals at Georgetown, Charleston, Johns Island and Port Royal, and numerous open-pile wharves mostly for shipping agricultural products, fish, oysters, pulpwood, wood products, and petroleum products. Marinas are located at convenient intervals along the waterway where limited supplies and repair facilities are available for both commercial vessels and pleasure craft. Facilities are considered adequate for existing commerce and recreation requirements. Operations and results during fiscal year. Maintenance: The pipeline dredge Arlington performed maintenance dredging by contract during March-May 1971, restoring project dimensions in 7 shoaled areas from Winyah Bay to Charleston, 7 shoaled areas from Charleston to Port Royal, and Shem Creek, removing a combined total of 802,633 cubic yards of material for $360,038. Construction of spoil areas and installation of Government furnished spillways was completed by Cape Romain Contractors, Inc., July-November 1970, at a cost of $26,868. Clearing and snagging by the U. S. maintenance vessel Snell and hired labor was performed at a cost of $40,674. Surveys and supervision costs were $175,529. Condition at end of fiscal year.

Also, a 10-foot depth by 110-foot width channel on the Mount Pleasant side of the harbor into Shem Creek to U.S. Highway 17 bridge, and a 30-foot anchorage basin in the lower harbor between Castle Pinckney and Fort Moultrie. A 40-foot channel estimated to cost $6,060,000 was authorized to be executed when found necessary in the interests of national defense from the 40-foot contour in Atlantic Ocean to U. S. Naval Base. For further details see page 425 of Annual Report for 1962. (See Table at End of Chapter for Acts Authorizing Existing Project.) 7-2 CHARLESTON, S.C., DISTRICT Local cooperation. Local interests have fully complied with their responsibility to date but are experiencing difficulty in securing suitable disposal areas for dredged material for continued future maintenance. Terminal facilities. Piers and slips extend for about 1 mile along the eastern waterfront of the city of Charleston with an additional mile of marginal wharves. The South Carolina State Ports Authority operates 8 piers for fruit, wood, cold storage facilities and general cargo, a grain elevator and a beltline railway which serves the entire Cooper River waterfront. Modern facilities are also at wharves of 7 major petroleum companies including storage tank farms. Modern facilities for marine repairs and servicing are available at Detyens Shipyard, located approximately 10 miles northeast of Charleston on the Wando River.. The U.S. Navy Department has modern facilities for construction and maintenance of naval vessels including atomic submarines. Loading docks and storage areas for missile-carrying type vessels have also been constructed and are being operated by the U.S. Navy. For further details see Port Series No. 13, Corps of Engineers. Operations and results during fiscal year. Maintenance: The pipeline dredges Cherokee, Clinton, Hampton Roads and Arlington performed maintenance dredging and dike repairs by contracts during August 1970-April 1971, removing 3,637,142 cubic yards of material for $1,311,033. The hopper.dredge Gerig and hired labor performed maintenance dredging in the entrance channel during July 1970, removing 262,532 cubic yards of material at a cost of $208,572. Surveys and supervision costs were $181,479. Condition at end of fiscal year. Jetties protecting the entrance, channel across the bar were completed in 1895. The existing project was completed in October 1962, except for the national defense portion. Federal costs under the existing project to date have been $3,328,349 for new work and $30,676,400 for maintenance, a total of $34,004,749. 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 back 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. Advance Engineering and Design Studies were initiated after funds were released in April 1969 and studies continued through FY 71. Condition at end of fiscal year. The project is in the advanced planning stage. Target date for completion of General Design Memorandum is 1 November 1971. 6. GEORGETOWN HARBOR, S.C. Location. The harbor is located on the coast of South Caroliha 50 miles northeast of Charleston Harbor and 90 miles southwest of entrance to Cape Fear River, North Carolina. (See U.S. Coast and Geodetic Survey Chart No. 787.) Previous projects. For further details see page 1806 of Annual Report for 1915; page 549 of Annual Report for 1938; and page 442 of Annual Report for 1944. Existing project. The authorizations provide for a channel 27 feet deep with varying widths of 600 feet to 400 feet from the Atlantic Ocean to and including a turning basin at the U.S. Highway No. 17 bridge over Sampit River, a total of 17.9 miles. The project also provides for the continued maintenance to a depth of 18 feet and a width of 400 feet for the bypassed portion of Sampit River opposite the city of Georgetown. (See Table at End of Chapter for Acts Authorizing Existing Piroject.) Local cooperation. Fully complied with. 7-3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Terminal facilities.

OTHER AUTHORIZED NAVIGATION PROJECTS (See Table 7-C) 11. NAVIGATION ACTIVITIES PURSUANT TO SECTION 107, PUBLIC LAW 86-645 (PREAUTHORIZATION) No fiscal year costs were incurred for studies in Port Victoria, located on the Colleton River in Beaufort County, South Carolina; however, work on a detailed project report which was scheduled for completion in September 1971 was suspended in June 1970 at the 7-4 CHARLESTON, S.C., DISTRICT request of the Secretary of the Interior because of unresolved questions about the ecological effects on channelization of the Colleton River. Environmental controversies persuaded the chemical company whose planned plant construction required such navigational improvement to cancel its plans. Accordingly in April 1971, the South Carolina State Ports Authority as the local sponsor, recommended termination of the study, and it was deauthorized in June 1971. During the fiscal year, review comments on the detailed project report on Town Creek, near McClellanville, Charleston County, South Carolina, suggested that consideration be given to the need for dredging the ocean bar at the mouth of Five Fathom Creek in order to give it usable depths compatible with the 10-foot channel proposed to Town Creek. This, and other revisions were in progress at the end of the fiscal year, with no fiscal year costs incurred. At the request of local interests, a reconnaissance report was initiated in June 1971 with respect to the feasibility of restoring depths adequate for commercial fishing vessels in the Calabash River (Brunswick County, North Carolina) from its connection with the Atlantic Intracoastal Waterway to the town of Calabash. No fiscal year costs were incurred. 12. NAVIGATION WORK UNDER SPECIAL AUTHORIZATION Snagging and clearing for navigation (Sec. 3 of 1945 River and Harbor Act, Public Law 14, 79th Cong.) Fiscalyear cost: None. BEACH EROSION CONTROL 13. HUNTING ISLAND BEACH, S.C. Location. Hunting Island is a state park comprising about 1,850 acres of wooded land and is located along the southeastern shore of South Carolina in Beaufort County, 16 miles east of the town of Beaufort, 9 miles southwest of Edisto Beach, and 35 miles northeast of Tybee Roads at the mouth of Savannah River. (See U.S. Coast and Geodetic Chart No. 793.) Existing project. The authorized project provides for periodic nourishment of about 10,000 feet of beach on the northern part of the island with initial placement of 750,000 cubic yards of sand for advance nourishment, and construction of one prestressed concrete groin at the north end of the island. Federal participation in periodic nourishment is limited to a period of 10 years. (See Table at End of Chapter for Acts Authorizing Existing Project.) Local cooperation. All requirements of local cooperation have been met by the St&te of South Carolina and accepted by the Chief of Engineers. The state contributed 30 percent of the cost of the initial project construction, and agreed to contribute a similar percentage of the costs of periodic nourishment during the 10-year period following initial construction. Operations and results during the fiscal year. A contract was awarded on 13 April 1971 in the amount of $485,125 for the first renourishment, consisting of the placement of 750,000 cubic yards of sand along the 10,000-foot feeder beach. Actual pumping of sand began on 29 May 1971. Condition at end of fiscal year. The first renourishment was designed to restore the feeder beach to the condition prevailing after the initial beach nourishment. While this was only about 40 percent complete at the end of the fiscal year, the most heavily used segment of beach was nourished first in order to meet the summertime needs of the park. 14. BEACH EROSION CONTROL UNDER SPECIAL AUTHORIZATION activities pursuant to section 103, Public Law 87-874 (preauthorization) None. FLOOD CONTROL 15. YADKIN RIVER, N.C. Location. The river rises on the eastern slope of the Blue Ridge Mountain in western North Carolina, flows generally easterly about 100 miles to the vicinity of Donnaha, North Carolina, thence southeasterly 104 miles to its confluence with Uwharrie River near Badin, North Carolina, 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, North Carolina, 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 Yadkin. Present planning considers only the two-reservoir 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 Authorizing Legislation.) Funds of $131,500 were 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. 15A. W. KERR SCOTT DAM AND RESERVOIR, YADKIN RIVER, N.C. Location. W. Kerr Scott Dam and Reservoir is on Yadkin River, North Carolina, about 6 miles upstream 7-5 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 top of dam 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 (Code 710) cost $43,921. Maintenance: Operation and maintenance cost $322,625. During the fiscal year the project had a visitation of 619,239. 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. During August, the dam received the most severe test since its construction. The stored inflow reached an elevation of 1060.2 feet msl, 30.2 feet above normal pool, and prevented an estimated $4,375,500 in downstream damages. 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. 15B. REDDIES RIVER LAKE, N.C. Location. Reddies River flows into the Yadkin River near the town of North Wilkesboro, North Carolina, and is a tributary to the Yadkin-Pee Dee River.

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. Preconstruction planning funds were appropriated in FY 70, but the funds were held in budgetary reserve throughout FY 70. Work began in January 1971 on the General Design Memorandum and it is scheduled for completion in March 1973. (See Table at End of Chapter for Acts Authorizing Existing Project.) Local cooperation. The state of North Carolina has given letters of intent to fulfill the local cooperation requirements necessary for water supply and development of recreational facilities.

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 * All cost and financial statements for projects are listed at the appear atthe end of this chapter. 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 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, end of this chapter. All other tables are referenced in text and also 8-1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 first session; and Lower Altamaha River and Darien Harbor, Ga., House Document 610, Seventy-seventh Congress, second session. (See Table 8-B for Authorizing Legislation.) 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 December 8, 1970 hired labor snagging work was initiated by crane barge No. 2 with towboat Piasa and the snagging was completed on April 17, 1971 after removing 3,419 snags at a cost of $33,799 including inspection and overhead. Other costs incurred, including condition and operation studies, hydrographic surveys, mapping of the rivers, and water pollution studies, amounted to $18,530. (See Table 8-A for Cost and Financial Statement.) 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 Sof 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, 1971, costs under the existing project were $60,847 for new work and $1,477,586 for maintenance, of which $13,533 were contributed funds, a total of $1,538,433. (See Table 8-A for Cost and Financial Statement.) 2. AQUATIC PLANT CONTROL 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 authorizing act provides that research and planning costs shall be borne fully by the United States. (See Table 8-B for Authorizing Legislation.) 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. Liaison was continued with the Georgia Game and Fish Commission who maintain surveillance of potential aquatic plant problem areas. Although aquatic plant control work is not imminent, the existing contract with the state of Georgia would permit the initiation of such work, depending on availability of funds. Cost during the fiscal year was $1,521. (See Table 8-A for Cost and Financial Statement.) 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 and one-half to 2 and one-half 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 duringfiscalyear. Maintenance: A combined contract for the Atlantic Intracoastal Waterway and Brunswick Harbor was awarded May 28, 1970 for maintenance dredging and during the period July 1 through August 7, 1970, contract pipeline dredge Cherokee removed 888,335 cubic yards of 8-2 SAVANNAH, GA., DISTRICT material from the main route of the waterway at Creighton Narrows, South River, Little Mud River, Altamaha Sound, Buttermilk Sound, Jekyll Creek and the auxiliary route around St. Andrews Sound, at a cost of $282,847, including inspection, overhead and other government costs. A continuing contract for maintenance dredging was awarded April 29, 1971, and dredging was initiated May 13, 1971 and through June 30, 1971, the contract pipeline dredge Arlington removed 273,922 cubic yards of material from the main route of the waterway at Buttermilk Sound, Little Mud River, and South River, at a cost of $132,962 ($31,606 FY 71 and $101,356 FY 72), including inspection, overhead and other government costs. Project condition surveys, condition studies, water pollution and environmental studies, and other government costs amounted to $45,649. Year-end general ledger adjustments and prior year costs in connection with a contract for construction of spoil dikes resulted in minus $683. Total cost for the fiscal year amounted to $359,322. (See Table 8-A for Cost and Financial Statement.) 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 Fields Cut, St. Augustine Creek, Wilmington River, Hell Gate, Bear River and Jekyll Creek. 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, 1971, were $763,599 for new work and $7,463,923 for maintenance, a total of $8,227,522. (See Table 8-A for Cost and Financial Statement.) 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, B-unswick 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. 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 11,444 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 May 28, 1970 for maintenance dredging in the Atlantic Intracoastal Waterway and Brunswick Harbor. During the period July 1 through August 7, 1970, the contract pipeline dredge Cherokee removed 308,989 cubic yards of material from Brunswick Harbor East River for a total cost of $118,173, including inspection, overhead, and other government costs. A continuing contract for maintenance dredging of East River and Terry Creek was awarded April 29, 1971 and work commenced May 13, 1971. During the period May 13, 1971 through June 30, 1971 contract pipeline dredge Arlington removed 421,759 cubic yards of material (57,000 cubic yards from Terry Creek) for a total of $136,739, including inspection, overhead, and other costs. Dredging operations in Terry Creek were stopped on June 13, 1971 at the request of Governor Jimmy E. Carter of the state of Georgia, based on his concern for environmental impact of placing spoil material in marsh area. Resumption of the work has been postponed until local interests have furnished spoil areas satisfactory to Governor Carter. The U. S. hopper dredge Gerig dredged March 12, 1971 to April 11, 1971 and removed 865,514 cubic yards of material from the bar channel at a cost of $353,190. Engineering and design for proposed closure dike, closure dam, and drainage canal on Academy Creek cost $2,555; also $1,274 was spent for design to place targets on dredging range towers. A credit of -$474 was received during the fiscal year from local interests for maintenance agitation dredging operations. Routine condition surveys, water and air pollution studies, government supervision and administration, engineering and design, and engineering investigations in connection with model studies cost $46,607. 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 8-3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Harbor Range; in 27-foot channel, 17 feet above Second Avenue. Costs for existing completed project to June 30, 1971, were $12,735,334, of which $3,430,143 was for new work including $10,000 contributed funds and $9,305,191 for maintenance. (See Table 8-A for Cost and Financial Statement.) 5. SAVANNAH HARBOR, GA. Location. Harbo'r 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 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 fedt 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. Latest approved estimate of total Federal Cost for new work modification (approved September 1971) is $20,894,000 ($10,519,000 for the Widening and Deepening of Channels and Turning Basin which includes $192,000 U. S. Coast Guard costs, and $10,375,000 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: Activities in connection with the Sediment Basin and Appurtenant Works modification continued with the contract pipeline dredge Windham removing 215,557 cubic yards of material for site preparation, 17,250 cubic yards for the hydraulic fill and tide gate structure, 3,818,521 cubic yards in dredging the Sediment Basin and 888,272 cubic yards of material from the Drainage Canal for a total of $1,303,100. The contractor for the Fort Jackson bank revetment work earned $76,945. Engineering and design and other government costs amounted to $148,200. Contract pipeline dredge No. 5 and pipeline dredge Pullen removed 4,464,168 cubic yards of material under the Widening and Deepening modification in the upper inner harbor and Marsh Island turning basin at a cost of $2,354,888, including $19,200 engineering and design and supervision and other costs of $53,500. Total cost for new work amounted to $3,883,133. (See Table 8-A for Cost and Financial Statement.) Maintenance: The U.S. hopper dredge Gerig dredged the bar channel from February 11, 1970 to March 11, 1970 and removed 582,442 cubic yards of material at a cost of $346,239, including other government costs. The U.S. pipeline dredge Henry Bacon dredged the inner harbor of the main channel during July 1, 1970 to June 30, 1971 and removed 5,695,193 cubic yards of material at a cost of $1,556,803, including other government costs. The project annually receives funds 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. Contract dredge Number 5 and dredge Pullen dredged 596,475 cubic yards of material from the upper inner harbor at a cost of $270,514, including other government costs. A contract was awarded July 7, 1970 for construction of bank revetments. 3200 linear feet of revetments were constructed at a cost of $308,791, including government costs. Maintenance of spoil dikes by hired labor draglines cost $348. Other maintenance of spoil dikes, including funds expended for contributed funds amounted to $86,576, including other goverment expenses. Dragging and sweeping, including supervision and inspection and overhead amounted to $6,817. General ledger unapplied advances at year end amount to -$98; credits received from contributed funds and for agitation dredging, -$113,787; credits 8-4 SAVANNAH, GA., DISTRICT received from agitation dredging of private shipping interests slips amounted to -$60,514; other income credits received for unauthorized dumping in spoil areas amounted to -$1,243. Distribution of Engineer yard costs, including overhead amounted to $79,508. Condition surveys, water and air pollution studies, inspections and reports, and government supervision and administrative costs were $143,894. Total operation and maintenance costs for the fiscal year amounted to $2,623,848. (See Table 8-A for Cost and Financial Statement.) 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, 34 feet at City Front and Marsh Island; in 36-foot channel, 33 feet at Garden City; in 30-foot channel, 30 feet at Port Wentworth. Costs of existing project to June 30, 1971, were $16,420,913 federal cost and $305,248 contributed funds for new work and $48,081,421 federal cost and $372,596 contributed funds for maintenance, a total of $65,180,178. (See Table 8-A for Cost and Financial Statement.) 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 Bridge, a total distance of about 181 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 Idck and dam at mile 187 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. 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 a terminal at Sylvania. These are supplemented by natural landings along the river and extensive facilities at Savannah. Operations and results during fiscal year. Maintenance: The contract pipeline dredge Donna Joe removed 70,228 cubic yards of material during the fiscal year at a cost of $112,076, including government costs. A continuing contract for construction of bank revetments was awarded April 23, 1970, and during the period July 1, 1970, to September 10, 1970, cost generated on this contract amounted to $104,059, including government cost. Another contract for construction of bank revetments was awarded May 21, 1971; however, construction was not commenced until after the end of fiscal year 1971; therefore a cost of only $6,619 was incurred during FY 71 for engineering and design and other minor government services. Snagging operations during the period March 20, 1971 to June 30, 1971 removed 1,130 snags at a cost of $86,114. Distribution of Engineer yard costs and other minor year-end general ledger adjustments amounted to $312. Routine operation and maintenance of the lock and dam, including condition and operation studies, water and air pollution studies, inspection and reports and other minimum essential activities cost $111,819. Total cost for the project for the fiscal year amounted to $420,999. (See Table 8-A for Cost and Financial Statement.) 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, 1971, were $12,141,490 of which $6,646,551 was for new work and $5,494,939 for maintenance. (See Table 8-A for Cost and Financial Statement.) 7. OTHER AUTHORIZED NAVIGATION PROJECTS (See Table 8-C.) 8-5 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 FLOOD CONTROL 8. PEACOCK CREEK, LIBERTY COUNTY, GA. Location. Peacock Creek is located in the eastern portion of Liberty County and empties into the Atlantic Ocean through North Newport River. Peacock Creek and tributaries drain a portion of the Fort Stewart Military Reservation and sizeable swamps in the vicinity of Hinesville, Flemington, and McIntosh, Georgia. Existing project. The authorized plan of improvement provides for channel clearing and excavation of approximately 6.8 miles on Peacock Creek, 3.3 miles on Captain Fleming Swamp, 4.8 miles on the main stem of 'Melvin Swamp, 4.2 miles on the minor stems of Melvin Swamp, 3.6 miles on the main stem of Goshen Swamp, and 1.7 miles on the minor stems of Goshen Swamp. Adequate waterway openings beneath state, Federal, and county maintained roads and lateral and on-farm drainage will be provided by local interests. Local cooperation. Local interests must (a) provide, without cost to the United States, all lands, easements, rights-of-way, utility relocations and alternations, waterway openings beneath roads, and highway or highway bridge construction and alterations necessary for project construction; (b) hold and save the United States free from damages due to the construction works, and adjust all claims concerning water rights; (c) maintain and operate the project, after completion, without cost to the United States, in accordance with regulations prescribed by the Secretary of the Army; (d) prevent future encroachment which might interfere with proper functioning of the project for flood control. Local interests have furnished assurances thai they will comply with the requirements of local cooperation. The County Commissioners of Liberty County indicate they will assist in every way possible to see that property owners construct the necessary lateral ditches on their property to assure the success of the project. The City of Hinesville and the Liberty County Board of Commissioners have requested the Corps of Engineers to perform the engineering and design work for which they are responsible, on a reimbursable basis. Operations and results during fiscal year. Preconstruction planning was approximately 88 percent complete at the end of the fiscal year. The field surveys were completed in October 1970 and plans and specifications were virtually complete. Condition at end of fiscal year. The proposed plan of improvement as contained in the Detailed Project Report was furnished to the Attorney General, State of Georgia and comments received were favorable. However, an environmental statement is currently being reviewed for the project and its approval by higher authority and concerned state and federal agencies will possibly necessitate delay in advertisement of the channel excavation contract until the middle or latter part of fiscal year 1972. Cost during the fiscal year was $30,133. (See Table 8-A for Cost and Financial Statement.) 9. INSPECTION OF COMPLETED FLOOD CONTROL PROJECTS Physical inspections of the Augusta and Macon levees were made during the fiscal year. Cost for fiscal year was $1,015. 10.

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 n the Everglades area west of the east coast protectiv, 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 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. Project also provides for navigation improvements suitable for recreational craft, consisting of locks and channel dredging in the upper Kissimmee and St. Johns River basins. 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. See also Table 9-U for principal features of locks and dam. Estimate of cost for new work (1971) is $403,000,000 Federal funds and $92,700,000 contributed funds, exclusive of river and harbor funds expended on previous projects. Local interests' costs in reviewing plans and specifications are expected to be $380,000. In addition, estimated cost to local interests of lands, rights-of-way, and relocations is $77,720,000. (See Table 9-B for Authorizing Legislation.) Local cooperation. (See Table 9-L for local cash contribution.) Local interests must also: provide lands, rights-of-way, and spoil disposal areas; hold the United States free from damages; bear the cost of maintenance and operation of all works except those having to do with regulation of Lake Okeechobee and the main control structures of conservation areas; construct and maintain lateral drainage facilities; prohibit encroachment on flood-carrying capacity of the improved channels; and assume cost of construction of all new highway bridges, relocations of existing bridges, and alterations to utilities incident to construction of the project. In addition, for small boat navigation channels, local interests must provide, maintain, and operate adequate public landings, sanitary and access facilities, and establish regulations prohibiting discharge of pollutants into the waters of the locks and channels by users thereof. Assurances of local cooperation have been accepted by the District Engineer for all items of work authorized to date except those for the Small Boat Navigation feature added in 1970 under Section 201 of the Flood Control Act of 1965. 9- 19 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Total estimated contributed funds amount to $92,700,000. Operations and results during fiscal year. (See Table 9-M for work accomplished.) Operating and care. a. Features completed under previous navigation project for Okeechobee Waterway and being maintained under this project are: a levee about 70 miles long following in general the south shore of Lake Okeechobee and a north shore levee 15.8 miles long; spillways at Ortona and St. Lucie locks; 5 hurricane gates; 20 gated drainage culverts through the levee; and 16 spillways along St. Lucie Canal. b. Features completed under existing project that are to be maintained with operation and maintenance funds are: (1) Levees 47, 48, 49, and 50-total length 63 miles and enlargement of existing levees L-D1, LD2, L-D3, L-D4, and L-D9, (2) spillway structures S- 10, S-11, S-12, S-18C, S-77, and S-78, (3) C-43 Sec. 4 (Caloosahatchee River), and (4) W. P. Franklin Lock and Dam. c. 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. One of the severest droughts of record has existed over the entire Central and Southhern Florida Project area since September 1970. Rainfall averaged about 35 inches over the area during the 1971 Fiscal Year. This is 17 inches below normal. By the end of March 1971 most aboveground storage in\the three water conservation areas had been depleted leaving Lake Okeechobee as the only major source of water supply for all of south Florida. In the Everglades, fires, caused mostly by careless campers, burned thousands of acres of sawgrass and other vegetation. Many of the recreational areas outside the park were temporarily closed to the public. Along the lower east coast, reduced water tables produced a threat of salt water intrusion to domestic water supplies. The main Miami well field reached its lowest level in 31 years of record. During varied portions of the drought period most municipalities south of the north Palm Beach County line passed ordinances forcing rationing of water. While voluntary rationing of water was all that was ever invoked for agricultural interest, forced rationing of water was being considered by the Central and Southern Florida Flood Control District at the beginning of June when water level conditions in the area began to improve. Conditions improved slightly in the latter part of May and June, but most water storage areas remained from one to three feet below their scheduled stage. At the end of June the total project area deficit below the scheduled storage, excluding Upper St. Johns Basin Lakes, amounted to 1,873,000 acre-feet. b. Corps of Engineers. (1) Lake Okeechobee. The net water supply to Lake Okeechobee from its 5,650-square-mile drainage area amounted to a negative 205,800 acre-feet during the 1971 Fiscal Year, as compared to 4.9 million acre-feet during the 1970 Fiscal Year. Rainfall on the lake totaled 33.05 inches for the Fiscal Year, which was 16.83 inches below normal. Inflow to the lake totaled 920,000 acre-feet, as compared to nearly 4.3 million acre-feet in FY-70. Stages on Lake Okeechobee were slightly above schedule during most of July and August. The peak stage of 14.23 feet occurred on 27 August. At that time the lake stage was on schedule and rising. From that point on deficit rainfall, high evaporation, and heavy agricultural demands lowered stages to a low of 10.3 feet on 6 June. An interim regulation schedule approved for 1970 only permitted raising the lower limits of the regulation schedule from 13.5 feet to 14.0 feet during June and July. This provided an extra 175,000 acre-feet of water at the beginning of the drought in September. During January, February, and March the Kissimmee River (C-38) discharge to Lake Okeechobee was 219,000 acre-feet, being required in connection with the Lake Tohopekaliga experimental drawdown for environmental improvement of that lake. Little of this discharge would normally have been discharged to Lake Okeechobee during this period. Without this discharge and without the 0.5-foot rise in the regulation schedule, it is conservatively estimated that the lake stage would have reached a record low of approximately 9.2 feet by 6 June. Regulatory discharges, made only during July and August, totaled 268,100 acre-feet for Fiscal Year 1971. Releases from the lake for irrigation, urban use, and Everglades National Park water supply totaled 753,000 acre-feet. (2) Water Conservation Area No. I began the Fiscal Year above schedule, reached a peak stage of 16.04 feet on 4 October, and receded to an elevation of 11.4 feet on 17 April. By the end of March most aboveground storage had been depleted. Net water supply to the area totaled 249,000 acre-feet as compared to 833,000 acre-feet during Fiscal Year 1970. Inflow to the area totaled 203,900 acre-feet. Rainfall over the area totaled 35.99 inches during the Fiscal Year, which was 20.49 inches below normal. Outflow from the area totaled 308,700 acre-feet which was distributed as follows: Regulatory 131,000 acre-feet, releases to the east for irrigation and salinity control 72,000 acre-feet, and seepage 105,700 acre-feet. (3) Water Conservation Area 2A began the 1971 Fiscal Year above schedule, with the peak stage of 13.95 feet occurring on 20 July. From this point stages receded to an elevation of 9.55 feet on 13 May. By the end of March most aboveground storage had been depleted. The net water supply to the area totaled only 110,800 acre-feet during Fiscal Year 1971, as compared to 1,430,000 acre-feet during Fiscal Year 1970. Inflow to the area totaled 213,800 acre-feet. Rainfall over the 9 - 20 JACKSONVILLE, FLA., DISTRICT area totaled 36.19 inches during the Fiscal Year, 14.65 inches below normal. Outflow from the area totaling 325,400 acre-feet was distributed as follows:* Regulatory 169,800 acre-feet, releases to the east for irrigation and salinity control 60,400 acre-feet, seepage 95,200 acre-feet. (4) Water Conservation Area 3A began the fiscal year above schedule, with the peak stage of 10.27 feet occurring on 3 October. From this point stages receded to an elevation of 6.38 feet on 13 May. Most aboveground storage had been depleted by the end of March. The net water supply to Area 3A during Fiscal Year 1971 totaled 163,200 acre-feet, as compared to 2,516,000 acre-feet during Fiscal Year 1970. Rainfall totaled 34.97 inches over the area during Fiscal Year 1971, which was 15.46 inches below normal. Outflow from the area through S-12 to ENP totaled 191,600 acre-feet regulatory, and 230,800 acre-feet non-regulatory. Outflow from Area 3A to the Miami area via the Miami Canal totaled 10,720 acre-feet regulatory, and 19,720 acre-feet for salinity control. Seepage to the east totaled 352,000 acre-feet. c. Central and Southern Florida Flood Control District. Project canals, structures, and pumping stations were operated by the Flood Control District in accordance with design criteria to supply irrigation water to the agricultural areas, maintain desirable canal levels, and prevent salinity problems in coastal areas. During the Fiscal Year about 79,800 acre-feet of water were pumped by the Flood Control District to Lake Okeechobee and the 3 water conservation areas. During the drought from October through May the Flood Control District released 445,600 acre-feet of water for irrigation from Lake Okeechobee via the agricultural canals. By January it was apparent that supplemental water from Lake Okeechobee would be needed to supply part of the Everglades National Park demands. In addition to the releases for agricultural demands during the period January through May an additional 114,700 acre-feet of water from Lake Okeechobee was transferred to the 3 water conservation areas for maintaining floor levels in the water conservation canals areas, for release to the east coast, and for Everglades National Park water supply. Of the amount transferred 63,800 acre-feet was released to the east coast, mainly for salinity control, and 28,800 acrefeet was released to the Everglades National Park. The total amount of water delivered to the park during the fiscal year, including regulatory releases, was 422,400 acre-feet. Minimum scheduled park demands were met throughout the fiscal year, except for June 1971 when only approximately 2,200 acre-feet of the scheduled 4,000 acre-feet was delivered. Condition at end of fiscal year. The project wasabout 46 percent complete. Planning for the entire project began in November 1948 and has been continued. For construction completed prior to Fiscal Year 1971, see Annual Reports for 1960-1970. Construction completed under existing project during the fiscal year is set forth in Table 9-N. All Federally maintained features of the project were generally in good condition at the end of the fiscal year. (For status of work under contract at end of fiscal year see table 9-0.) Total Federal costs under the existing project through June 30, 1971, were $186,445,826 for new work (excluding $906,797 preauthorization studies), $5,309,947 for maintenance, and $1,287,845 for operation and care, a total of $193,043,618. In addition, $35,410,097 has been expended from contributed funds for new work. 39. FOUR RIVER BASINS, FLA. Location.

(See Table 10-J) MULTIPLE PURPOSE PROJECTS INCLUDING POWER 45. ALABAMA-COOSA RIVERS, ALA. AND GA. Location. Alabama River is formed 18 miles above Montgomery, Alabama, 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, Georgia, 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, Alabama, 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 10 - 19 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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, Alabama, and for construction of Carters Dam, a multiple-purpose improvement on Coosawattee River, Georgia. Estimated cost 1971 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 improvements, exclusive of amounts expended on previous projects. 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 $606. Engineering, design, supervision, and administration cost $56,434. Maintenance: Operation and care of Claiborne lock cost $45,426, and maintenance of Claiborne lock amounted to $4,498. The U. S. pipeline dredge Collins, worked a total of 50.5 days removing 998,398 cubic yards of material from the Alabama River, at a cost of $207,958. Dredging done in Alabama River under contract amounted to $167,993. The U. S. snagboat ROS performed snagging in the Alabama River, a total of 15 days at a cost of $16,725. Miscellaneous surveys and investigations cost $131,334; reservoir operations cost $501; real estate activities cost $108; land engineering, design supervision, and administration cost $88,769; reconnaissance and condition surveys cost $352. Coosa River reservoirs cost $19,999. Total fiscal year costs for entire project, including lock and dam projects, amounted to $18,367,802 for new work and $1,319,833 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. Since all existing locks on the river are inoperative, through navigation on the Coosa River is impossible. 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. (See Table 10-K for developments proposed under existing project and 10- L or fiscal year costs for new work on overall project.) Constructing of Millers Ferry lock and dam is essentially complete. 45A. ALLATOONA LAKE, COOSA RIVER BASIN, GA. Location.

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 con-- tinued 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, 18,890 acres of vegetatio. were destroyed. State of Louisiana crews destroyed 11,730 acres of vegetation by chemical treatments only. Crews of the Corps destroyed 7,130 acres of vegetation using both chemical and mechanical methods. The alligatorweed flea beetle (agasicles), which was introduced in the United States as a result of research under this project, was found in Louisiana. The beetles successfully overwintered and are effectively attacking the alligatorweed in a number of locations. Cooperative efforts with others engaged in aquatic weed research continued. The annual meeting of the Interagency Research Advisory Committee for aquatic plant control was held in New Orleans. 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.

S. Highway 90 to Bayou Chene via Bayou Black and the Gulf Intracoastal Waterway. Estimated cost for new work (July 1971) is $13,500,000 Federal and $1,300,000 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 furnished assurances of local cooperation dated December 15, 1970, for St. Mary Parish, the area of their territorial jurisdiction. Of the two other parishes involved, Assumption and Terrebonne, the Assumption Parish Police Jury has furnished an Act of Assurance of Agreement and Designation for the Morgan City Harbor and Terminal District to perform in its parish. The Terrebonne Parish Police Jury objects to the Morgan City Harbor and Terminal District operating in its parish with expropriation powers and have not as yet given assurances for the project. 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 fiscal year 1970. Preparation of the general design memorandum continued and preconstruction planning is expected to be completed in fiscal year 1972. Condition at end offiscalyear. 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.

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 Natchez restored 7.6 miles of channel to 16-foot depth between miles 0 and 8.1 below mouth of river, during period July 3 through August 15,1970. Condition at end offiscalyear. Construction was initiated in fiscal year 1911 and completed in fiscal year 1914. 4. BARATARIA BAY WATERWAY, LA. Location. In Jefferson Parish, La., and extends about 37 miles southerly from junction of Gulf Intracoastal Waterway and Bayou Barataria near Lafitte Post Office. From its origin it extends southerly through Bayou Barataria, Bayou Dupont, a landcut (known as 11 -3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Dupre Cutoff) through marsh area, Bayou Cutler, Bayou St. Denis, and Barataria Bay to east end of Bayou Rigaud. At its southerly terminus it also connects with Barataria Pass and through that pass with the Gulf of Mexico. (See Coast and Geodetic Survey Charts 1050, 1116, and 1237, Geological Survey maps Barataria, Bay Dogris, Wilkinson Bay, and Barataria Pass.) Previous project.

Work by hired labor consisted of preparing plans and specifications for a contract for dredging bar channel, surveys, and channel patrol. Condition at end of fiscal year. Existing project was completed in 1931. 6. BAYOU LAFOURCHE AND LAFOURCHEJUMP 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 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 1971) is $8,030,000, Federal, and $3,400,000, non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $31,000. Excavation of a channel 6 11 -4 NEW ORLEANS, LA., DISTRICT 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 1971) 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: No action is apparent on this stretch by either the- Lafourche Parish Police Jury, the Jefferson Parish Council, the local assurers, or the State of Louisiana, Department of Public Works. Rights-ofway are not available due to multiplicity and other complications of ownership. 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. In 1969, the President of the Police Jury emphatically stated that acquisition of right-of-way for the auxiliary channel would not be abandoned until hurricane .protection was provided in the Parish; however, there is no evidence that such rights-of-way are being consummated. Terminal facilities. There are numerous private warehouses, wharves, and stiff-leg derricks for handling cane along bayou. At Lockport, Barker Barge Line has 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. Total cost of existing project to June 30, 1971, was $1,953,402, of which $1,175,203 was for new work and $778,199 for maintenance. In addition, $75,563 has been 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. 7. 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 11 -5 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 waterhyacinths 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. The local agency has upon request provided usable spoil-disposal areas for maintenance dredging. Terminal facilities. None. Operations and results during fiscal year. Maintenance by hired labor consisted of channel patrol 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. 8. 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 Vermilion Bay to Gulf Intracoastal Waterway, thence 9 by 100 feet to head of navigation (mile 52) at Lafayette, La. (fixed bridge at Louisiana State Highway 729, formerly State Highway 1092), with additional enlargement below Abbeville necessary to provide adequate capacity for floodflows; improvement of Vermilion River from Lafayette, La., mile 52, to its junction with lower end of Ruth Canal, mile 57.2 by both widening and deepening to provide a channel 6 by 60 feet, mean gulf level, in order to provide adequate capacity for flood discharges from upper Vermilion River Basin, and also serve irrigation interests by conducting flow of Ruth Canal to lower Vermilion River during rice season. Clearing and enlargement of channel from Ruth Canal to Bayou Fusilier by both widening and deepening to provide a cross section about 50 percent larger than that of existing channel. This improvement is required in interest of flood control in upper Vermilion basin. Enlargement of channel of Bayou Teche from its head in Bayou Courtableau to a point about 21 miles downstream thereof, by widening and deepening to provide a channel of 35-foot bottom width at minus 2 and minus 3, mean gulf level. Increasing height of Keystone Dam by 3 feet (later revised to 1.5 feet) by installation of a fixed crest spillway. (See individual report for Bayou Teche, La.) In connection with these improvements, the project also provides for replacement of an existing pontoon bridge at Woodlawn over Vermilion River with a vertical-lift structure and lengthening and strengthening approaches to five existing movable bridges over Vermilion River below Lafayette, La., located at Louisiana State Highway 43 at Perry, La.; Southern Pacific Railroad at Abbeville, La.; Louisiana State Highway 25 at Abbeville, La.; Milton, La.; and U.S. Highway 90 (Pinhook bridge) just below Lafayette, La. Similar work on existing fixed spans over nonnavigable streams is provided for on 11 bridges over Bayou Vermilion above Lafayette, La., and three over upper Bayou Teche. New work completed in 1957 cost $2,891,922. Project was reclassified "Operation and Maintenance, General" under category, "Navigation (Locks, Dams, Reservoirs, and Canals)" by authority of Chief of Engineers, April 23, 1956. Local cooperation. Fully complied with for new work. No action is presently being taken by local interests to acquire remaining rights-of-way for maintenance. Operations and results during fiscal year. Hired labor continued cooperative stream gaging, engineering studies, surveys and planning for recreational development. Condition at end of fiscal year. Construction commenced March 1944 and was completed March 1957, when Keystone Dam was raised to provide an increase of 1.5 feet in pool elevation, in order to increase flow through Ruth Canal into Vermilion River. This work was accomplished under navigation improvement "Bayou Teche, La." 9. BAYOU TECHE, LA. Location. Has its source in Bayou Courtableau, in St. Landry Parish, flows southeasterly for 125 miles, and joins lower Atchafalaya River about 10.5 miles above 11 -6 NEW ORLEANS, LA., DISTRICT Morgan City, La. (See Coast and Geodetic Survey Chart 1116, Mississippi River Commission alluvial valley maps, Palmetto, Opelousas, Carencro, Arnaudville, St. Martinville, Loreauville, Derouen, Jeanerette, Foster, and Belle Isle quadrangles.) Previous projects. For details see page 569, 1963 Annual Report. Existing project. Provides for a channel 8 feet deep and 80 feet wide on the bottom from mouth of stream to New Iberia, La., mile 54.5 thence 6 feet deep and 60 feet wide on the bottom to Keystone lock, 18 miles, and thence 6 feet deep and 50 feet wide on the bottom from Keystone lock to Arnaudville, La., 34 miles, to be secured by dredging, removing snags and overhanging trees, and construction of a lock and dam and regulating works.

Construction has not been initiated. 11. CALCASIEU RIVER AND PASS, LA. Location. Calcasieu River has its source in southwestern Louisiana, and flows southerly to the gulf. About 25 miles from the gulf it debouches into Calcasieu Lake, which is about 18 miles long. Connection between lake and gulf, about 7 miles long, is known as Calcasieu Pass. (See Coast and Geodetic Survey Charts 591 and 592; Geological Survey maps, Edna, Thompson Bluff, Hecker, Moss Bluff, Lake Charles, West Lake, Moss Lake, Hackberry, Sweet Lake, Brown's Lake, Holly Beach, Grand Bayou, and Cameron quadrangles; and Corps navigation maps of Intracoastal Waterway and Atchafalaya River system.) Previous project. For details see 1936 and 1938 Annual Reports, pages 719 and 819, respectively. Existing project. Provides for a channel 40 by 400 feet (35.9 miles long) from Lake Charles to sea end of jetties in Gulf of Mexico; an approach channel 42 by 800 feet from sea end of jetties to 42 feet deep in the gulf; extension of 35- by 250-foot channel from its present upstream limit at mile 34 to vicinity of U. 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 existing jetties 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 finalizing transfer to the United States of 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 fiscal year. Maintenance by hired labor consisted of condition and operation studies, operation and maintenance of the salt-water barrier, and maintenance dredging by dredges. The dredge McFarland removed 3,365,300 cubic yards of shoal between miles 0 and minus 7 in restoring channel during the period October 1 to 20, 1970. The dredge Langfitt removed 6,361,000 cubic yards of shoal' between miles 0 and minus 7 during the period November 4 to December 3, 1970, and June 11 to 30, 1971. Minor repairs were made to dredging target November 3 to 9, 1970, and Langfitt wharf, structure 700, at Cameron during the period March 10 to 12, 1971. Maintenance by contract consisted of restoring the channel from miles 15.5 to 5.0. Work was started December 16, 1970, and completed April 17, 1971, with the contract dredges Galveston and Louisiana, removing 5,521,834 cubic yards of shoal material. Scour repairs were made at Calcasieu River salt-water barrier during the period July 3 to 21, 1970, by placing 9,888 tons riprap and 2,533.7 tons quarry-run stone on down river side adjacent to the barrier structure. 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 11-D at end of chapter for work accomplished under each modification. 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. Total cost of existing project to June 30, 1971, was $42,609,103, of which $27,311,396 was for new work and $15,297,707 for maintenance. In addition, $107,837 was expended for minor rehabilitation (Code 820). 11 -8 NEW ORLEANS, LA., DISTRICT 12. CHEFUNCTE RIVER AND BOGUE FALIA, LA. Location. Chefuncte River rises in upper portions of Tangipahoa and Washington Parishes, La., and flows southerly through St. Tammany Parish into Lake Pontchartrain, opposite New Orleans. (See Coast and Geodetic Survey Chart 1269, Mississippi River Commission alluvial valley map, and Covington quadrangle.) Previous project. For details see page 731, 1913 Annual Report, and page 783, 1938 Annual Report. Existing project. Provides for channel 10 feet deep at mean low gulf level over a bottom width of 125 feet from that depth in Lake Pontchartrain to mile 3.5 of Chefuncte River and 8 feet deep, mean low gulf, to Washington Street, Covington, La. Improvement is 14 miles long. Under ordinary conditions mean range of tide at mouth is about 10 inches, and near Covington about 3 inches, and extreme range about 14 and 5 inches, respectively. Variation of water surface in upper Chefuncte River and Bogue Falia, due to floods, is about 8 feet; that in lower Chefuncte River at Lake Pontchartrain, due to winds, is about 3 feet. Cost of new work for existing project was $53,121. Local cooperation. Fully complied with. Terminal facilities. None on the Bogue Falia. On Chefuncte River, town of Madisonville and State of Louisiana, through the Department of Public Works, constructed facilities at Madisonville. State of Louisiana also constructed boathouse facilities for the Coast Guard Auxiliary at the mouth of Chefuncte River. Wharves used in connection with the two boatyards have been constructed at Madisonville and Houltonville and these, in addition to small wharves constructed by owners of pleasure boats, are adequate for navigation needs. On both waterways additional sites are available if needed. Operations and results during fiscal year. Maintenance by hired labor consisted of channel patrol and preparation of plans and specifications for dredging bar channel. Condition at end of fiscal year. Because of maintenance work performed under previous project, work under project adopted in 1930 was completed in 1929, and modification adopted in 1958 was completed in April 1959, between miles minus 0.19 and 1.35 as adequate dimensions are available in river from miles 1.35 to 3.5. Obstructions in Chefuncte River and Bogue Falia were originally removed in 1886, and channel through bar was originally dredged in 1903. 13. CYPRESS BAYOU AND WATERWAY BETWEEN JEFFERSON, TEX., AND SHREVEPORT, LA. Location. Cypress Bayou rises in northeast Texas and Sflows southeasterly to Caddo Lake, thirough this lake to Big Willow Pass, and through Big and Little Willow Passes, Soda Lake, Twelve Mile Bayou, new diversion canal, and Cross Bayou to Red River at Shreveport, La., a distance of about 132 miles. (See Geological Survey State maps and Quadrangle maps.) Cypress Bayou proper ends where it enters Caddo Lake, but the name is frequently applied to the whole waterway described above. Existing project. Dredging and straightening channel, removing obstructions, and clearing banks for 66 miles from Red River at Shreveport, to Jefferson, and a 3,400-foot long, fixed, on pile foundation, dam at foot of Caddo Lake, La. and Tex., about 23 miles above mouth of Jefferson-Shreveport Waterway and 2 miles below Mooringsport, La. Dam was completed December 21, 1914, at a cost of $100,553. Cost of new work, excluding modification of August 13, 1968, was $202,817. Reconstruction of dam authorized by 1965 Flood Control Act. (See report under flood control feature.) Dam will be modified under authority of 1968 River and Harbor Act to provide navigation under "Red River Waterway" project. Local cooperation. None required. Terminal facilities. None at Shreveport, La. Two publicly-owned brick warehouses, 50 by 150 feet, at Jefferson, Tex., and three oil company facilities at Mooringsport, La., a covered dock, 60 by 60 feet opened to all small boats, a pipe rack not decked, and boatways. Warehouse at Jefferson has not been used for several years, since no commerce has moved in that vicinity. facilities considered adequate for present commerce. Operations and results during fiscal year. Clearing and snagging of Cypress Bayou was accomplished by leased dragline from Jefferson, Tex., to Caddo Lake, La., during the period January 26 to March 2, 1971. Condition at end of fiscal year. Dam at foot of Caddo Lake was completed in December 1914, completing project. Its construction and maintenance insure a 4- foot navigable depth at low water from that point to Jefferson, head of navigation, but prevent possible navigation to Shreveport, except for such light draft boats as may pass over dam at high stages. Below dam, navigation is largely dependent upon backwater from Red River. A stage of from 15 to 24 feet on Red River gage at Shreveport, depending on runoff from Cypress Bayou drainage area, is necessary to provide a 4-foot depth up to dam. Such stages are short in duration and irregular in occurrence. Replacement of Caddo Dam is under construction and is reported separately as Caddo Lake, La. 14. 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. 11 -9 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 1971) is $3,118,100. Estimated non-Federal cost for the existing project is $171,000. In addition, Coast Guard is to provide navigational aids at an estimated cost of $19,100. 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 to lock, and condition and operation studies. Maintenance by contract consisted of dredging in Freshwater Bayou channel by the dredge Louisiana, from mile 1.27 to 0 (inshore) and mile 0 to minus 3.60 (offshore) during the period July 9 to September 6, 1970. 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. 15.

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 11 - 10 NEW ORLEANS, LA., DISTRICT 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 Plaquemine, La., improvement of Franklin Canal as a connecting channel from Gulf Intracoastal Waterway (mile 121) to Franklin, La., to afford a channel 8 feet deep and generally 60 feet wide with a width of 100 feet in its upper 300 feet; and a salt-water guard lock (Calcasieu lock) in 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 299.4 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 $102,913,827 Federal and $16,142,000 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 1971), $60,148,531 Federal and $11,707,400 non-Federal, including $36,300,000 Federal and $11,700,000 non- Federal for modification of October 1962, and $8,380,000 Federal and $7,400 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 11 - 11 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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. Replacement of Vermilion lock: Local interests are to provide without cost to the United States all lands, easements and rights-of-way required for construction and subsequent maintenance of the replacement lock and approach channels thereto, and hold the United States free from damages due to construction and maintenance of the project, including erosion of the channel beyond the rights-of-way furnished for the replacement lock and the approach channels thereto. 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: Work continued on preparation of general design memorandum early in fiscal year and it is about 50 percent complete. However, all planning for the new lock has been deferred until such time as the size of the new facility can be developed from an on-going systems analysis of waterway commerce. Maintenance by hired labor: Real estate activities, condition and operation studies, non-cooperative stream gaging, investigation and surveys, condition surveys, and channel patrol continued. Locks, bridges, and waterways were operated and maintained. Fender systems were repaired at Algiers, Calcasieu, Harvey, Inner Harbor navigation canal and Vermilion locks.

Provides for additional navigation outlets in the vicinity of Venice, La., by enlargement of the existing channels of Baptiste Collette Bayou and Grand-Tiger Passes to 14 by 150 feet with entrance channels in open water 16 by 250 feet and jetties to the 6-foot depth contour, if and when justified, to reduce cost of maintenance dredging. Estimated cost of new work (July 1971) is $6,380,000, Federal, and $1,426,000 non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $80,000. Local cooperation. 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 necessary retaining dikes, bulkheads and embankment therefor or the costs of such retaining works; accomplish without cost to the United States such alterations as required in pipelines, cables, and other improvements, as well as their maintenance; and hold the United States free from damages due to the construction and maintenance of the project, including but not limited to erosion beyond the rights-of-way furnished, and damages to oyster beds and other fisheries. Assurances of local cooperation dated May 28, 1970, were received from the Plaquemines Parish Commission Council and accepted by the United States on December 18, 1970. Terminal facilities. In the Venice area, each operator of a construction, repair, or supply facility provides dock and transfer facilities to meet his own needs or arranges to use those of another. These facilities are considered adequate for the anticipated traffic. If new industry or supply facilities are established, they would provide any needed terminal facilities for their use. Ample areas for future expansion are available. Operations and results during fiscal year. Hired labor forces are proceeding with the work required for preparation of the general design memorandum for the Baptiste Collette portion of the project which is scheduled for submission in fiscal year 1972. Surveys have been completed and the remaining design effort is proceeding on schedule. Preparation of the Baptiste Collette general design memorandum is approximately 15 percent complete. Condition at end of fiscal year. Construction has not commenced. 24. OVERTON-RED RIVER WATERWAY, LA. Location. In State of Louisiana between junction of the Old and Mississippi Rivers and Shreveport, La., along the Old and Red Rivers, through landcuts and natural channels on the south bank of Red River. (See Geological Survey State maps and Mississippi River Commission alluvial valley quadrangle, maps.) Existing project. Provides for a channel 206 miles long, 9 feet deep and 100 feet wide, extending from Mississippi River at mile 301 above Head of Passes through Old River and Red River to mile 31, thence by a lateral canal extending through landcuts and existing waterways, across the Mississippi-Red River backwater area and along south bank of Red River floodplain to Shreveport, La., and construction of nine locks and a pumping plant on Red River near Shreveport. Floods ordinarily cause fluctuations of stage between high and low water in Old River, Red River, and the backwater area of from 30 to 45 feet; the fluctuations of stages on the south bank tributary streams are somewhat less. Estimated cost for new work, (lower 31 miles only), (July 1971) is $15,700,000 Federal and $53,000 non- Federal., Local cooperation.

Construction has not been initiated. 27. REMOVING WATER-HYACINTH, LA. 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 fiscal year. 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 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 7,081 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. 28. TANGIPAHOA RIVER, LA. Location. Originates in State of Mississippi and flows southerly to Lake Pontchartrain, La., about 110 miles.

Normal range of tide is from 16 to 40 inches; hurricane tides may exceed 6 feet. Construction was completed at a cost of $1,068,142; except for an estimated $1,573,000 for extension of jetties to 9-foot depth contour to be constructed if necessary. Local cooperation. Fully complied with. Operations and results during fiscal year. Hired labor forces carried on reconnaissance surveys. Maintenance by contract consisted of repairs to existing east and west 11 - 20 NEW ORLEANS, LA., DISTRICT jetties by placing stone and clam shells and construction of 325 linear feet of dike extension, groin, and new tie-in dikes at west jetty. Work was accomplished during the period February 2 and March 1, 1971. Condition at end of fiscal year. Project is physically complete, unless at a later date it is found necessary to extend jetties to 9-foot depth contour. Project construction was initiated in July 1948 and completed in June 1950, during which period the 9- by 80-foot channel from Empire, La., to Gulf of Mexico, 10 miles, was excavated by contract. A total of 4,061 linear feet of jetties was constructed by contract to 6-foot depth contour, 1,818 linear feet on east jetty and 2,243 linear feet on west jetty, from June 23, 1949, to February 18, 1950, and February 2 to March 1, 1971. 30.

Cooper Dam and Reservoir is about 4 miles southeast of Cooper, 13 miles north of Sulphur Springs, Tex., and is at mile 23.2 on South Sulphur River, which rises in Fannin County, Tex., and flows generally east for about 80 miles to its confluence with North Sulphur River to form Sulphur River. Existing project. Provides for construction of an earthfill dam with maximum height of about 73 feet, 15,882 feet long at its crest, one controlled (service) spillway, and an emergency uncontrolled spillway. Reservoir area will be 22,740 acres at top of flood control .pool, 5,084 acres at top of sediment pool, and 19,305 acres at top of water-supply pool. The reservoir will contain 131,400 acre-feet of flood control storage space, 273,000 acre-feet of municipal and industrial water supply space, and 37,000 acre-feet of sediment storage. Also provides for channel clearing, realinement, and enlargement; enlargement and extension of existing levees; and construction of appurtenant drainage works along main stem of Sulphur River above mile 126; channel clearing, realinement and enlargement and levee enlargement and modification of appurtenant drainage works on Cuthand Creek below mile 24, on Sulphur River below mile 70, except in proposed Cooper Reservoir, miles 29 to 42, and on Middle Sulphur River below mile 8; channel clearing and realinement of Brushy Creek below mile 5; and levee enlargement on North Sulphur River between miles 1 and 5. Uncompleted channel and levee improvements lying between the damsite and Texas Highway 37 will be deleted in the interest of accommodating Texas Water Plan. Estimated Federal cost for new work (July 1971) is $42,800,000, which includes $17,530,000 to be reimbursed by water supply users over a 50-year period, and $2,234,000 non- Federal, including a $1,900,000 cash contribution for modifications to accommodate the Texas Water Plan. This estimate is based on a reservoir containing 273,000 acre-feet of water supply. Estimated non- Federal cost for the levee and channel work is $334,000. Local cooperation. Except for Cooper Reservoir, local interests must furnish lands and rights-of-way, and alter and relocate highways and related facilities and utilities, except railroads, for construction; hold the United States free from damages; maintain and operate all works after completion, and preserve channel capacities by preventing encroachment. Local agencies furnished rights-of-way for first two phases of work on levees and channels downstream from Cooper Dam. Right-of-way acquisition for part II, for channels and levees downstream from Cooper Dam, is essentially complete, except for that required below mile 140.4, Sulphur River (Magnolia Pipeline Crossing). Right-of-way acquisition for this portion of project is inactive pending resolution of a controversy among local interests as'to the responsibility for relocation of the pipeline. Right-of-way acquisition for part III is no longer required because these improvements have been deleted in the interest of accommodating the Texas Water Plan. Operations and results during fiscal year. Surveys, planning, and negotiations with cooperating agencies were continued by hired labor. Work on the detail design memorandum for the dam and reservoir was initiated April 23, 1971, after the site located in the south abutment of the dam at station 27@00 was approved. Land acquisition continued. A contract for construction of levees and channels, Part II, was initiated March 18, 1971, and was approximately 8 percent complete when work was halted May 26, 1971, by a court injunction. Approximately 3.1 miles of channel were excavated during that period. Condition at end of fiscal year. Construction of project began July 1958 and is 16 percent complete, with 14.2 miles of South Sulphur River and 6.3 miles of Middle Sulphur River channels excavated; and 3.4 miles of levee embankment on South Sulphur River and 7.3 miles of levee embankment constructed on Middle Sulphur River, all upstream from Cooper Reservoir.

Section 104 of the River and Harbor Act of 1958 (PL 85-500), as amended by the River and Harbor Acts of 1962 and 1965, provides for control and progressive eradication of water hyacinth, alligatorweed, Eurasian water milfoil, and obnoxious aquatic plant growths, from navigable 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. Research and planning costs are borne fully by the United States. Local cooperation. Officials of the Arkansas State Plant Board have the authority to participate in the Aquatic Plant Control Program in Arkansas in accordance with the Arkansas Plant Act (77-101-77-116, Arkansas Statute 1947). A letter supporting this advice and indicating the interest and intent of the state has been received. It is considered that the state will meet program requirements by formally entering into an agreement following approval of the General Design Memorandum by the Chief of Engineers. The state of Arkansas will be required to share program costs, to the extent of 30 percent, provide right-of-entry where required, and hold and save the United States free from claims which might arise due to program operations. Operations and results during fiscal year. There has been no previous Federal program for control of aquatic plants in Arkansas. Investigations up to the present time have been limited to a reconnaissance survey of the state, conducted by the Tulsa, Little Rock, Memphis, and Vicksburg Districts, and the Arkansas State Plant Board. A design memorandum is being prepared to initiate a project to control known infestations of obnoxious aquatic plants within the state. * 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. 12 - 1 1. 2. 3. 4. 5. 6. REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 2. LAKE PROVIDENCE HARBOR, LA. Location. Hagaman Chute, a secondary channel of the Mississippi River at mile 484 above Head of Passes, and about 3 miles south of Lake Providence, La. Existing project. A dredged harbor channel about 0.7 mile long and 150 feet wide with a project depth of 9 feet in Hagaman Chute from the Mississippi River. Channel was widened to 400 feet in front of and upstream from port area a distance of 800 feet to provide a turning basin. Local interests constructed retaining dikes to provide the disposal area for material excavated from channel and turning basin. Resulting hydraulic fill provides a raised port area. Federal cost of completed work was $198,859; excluding preauthorization study costs of $9,678. Total non-Federal cost was $233,400, including cost of retaining dikes, and a cash contribution of $35,000. In addition, local interests have spent $1,022,000 for port facilities. Local cooperation. Fully complied with. Terminal facilities. Local interests provided port facilities. Operations and results during fiscalyear. Leased dredge G. A. McWilliams moved 267,666 cubic yards of material for maintenance in harbor channel and turning basin. Condition at end of fiscal year. The project was completed in 1963 and is being maintained. 3. OUACHITA AND BLACK RIVERS BELOW CAMDEN, ARK. Location. Ouachita River rises in Polk County, Ark., and flows southeasterly and southerly about 600 miles. Below its confluence with the Tensas and Little Rivers at Jonesville, La., it is called Black River, which enters Red River 35.5 miles from the Mississippi River. Previous projects. See page 683 of Annual Report for 1962 for details. Existing project. See page 684 of Annual Report for 1962 for details of existing 6.5-foot navigation project. New work for completed project cost $4,574,551, exclusive of amounts expended under previous projects. Modified project and project for Red River below Fulton, Ark., provide for a channel 9 feet deep and 100 feet wide in Red River between Old River and mouth of Black River, and in Black and Ouachita Rivers from mouth of Black River to Camden, Ark. This will be accomplished by construction of four new locks, 84 feet by 600 feet, new dams, channel realignment, and mitigation measures to preserve Catahoula Lake for migratory waterfowl. Jonesville Lock and Dam will replace existing Lock and Dam No. 2; Columbia Lock and Dam will replace existing Lock and Dams Nos. 3, 4, and 5; Felsenthal Lock and Dam will replace existing Lock and Dam No. 6; and Calion Lock and Dam will replace existing Lock and Dam No. 8. The River and Harbor Act of 1970 authorized establishment of Federal migratory waterfowl refuges along Bayou D'Arbonne (14,700 acres) in connection with Columbia Lock and Dam and at Felsenthal Lock and Dam (65,000 acres). Approved (1971) estimated cost for new work for 9-foot navigation project is $132,385,000, including $129,000,000 Federal and $3,385,000 non-Federal for lands, damages, and relocations. Local cooperation. All local obligations to date have been met in Louisiana. Necessary rights-of-way have not been obtained in Arkansas. Terminal facilities. Public loading docks are at Columbia, La., and Camden, Ark. Privately-owned docks and loading and unloading facilities are at Columbia, Monroe, and Sterlington, La., and El Dorado, Calion, and Camden, Ark. Two grain handling facilities and petroleum-loading facility are in the vicinity of Jonesville, La., and a grain-handling facility is in the vicinity of Acme, La. Operations and results during fiscal year. Construction of Columbia lock was completed during the fiscal year. Construction of Jonesville lock and dam is underway. Planning and design for other features in the Jonesville and Columbia pools are continuing. Design activities for Felsenthal and Calion locks and dams and related features have been curtailed pending solution of rightof- way problems in Arkansas. One leased cutterhead dredge maintained existing 6,5-foot project depth, removing 935,000 cubic yards of material. Snagging and clearing was accomplished where required and the six locks and dams were maintained and operated throughout the fiscal year. Condition at end of fiscal year. The 6.5-foot project is complete and being maintained. Planning and design for 9-foot navigation project started in fiscal year 1962 and is continuing except as noted above. Construction at Columbia lock and dam started in February 1964. The dam was completed in November 1968 and the lock was completed in January 1970. Construction at Jonesville lock and dam started in May 1967. The lock and dam are approximately 98 percent complete. (See table 12-C on lock and dams, Ouachita and Black Rivers, Ark. and La.) 4. YAZOO RIVER, MISS. 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 (1971) of $78,300,000; (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 (1971) of $56,600,000 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 (1971) is $139,253,000. 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 was completed. Dam 27: Project is complete. Maintenance: Work consisted of 11,800 feet of dike repair and 39,600 feet of revetment repair. U. S. plant hired labor performed channel dredging at 28 locations, removing 4,831,600 cubic yards of material from main channel. Channels dredged had a combined length of 12.2 miles, an average width of 290 feet, and an average gain in depth of 7.0 feet. Condition and operation studies, recreation planning, engineering and design, and operation and maintenance of lock 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 79 percent complete. Work required to complete the project includes construction of 34,285 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 12.16 feet for fiscal year 1970 and 11.58 feet for fiscal year 1971. A study is underway to determine whether project 14 -2 ST. LOUIS, MO., DISTRICT criteria need to be revised in order to assure a dependable 9-foot project depth. 5. OTHER AUTHORIZED NAVIGATION PROJECTS. See table 14-C. 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 (1971). 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 $12,320,000 (1971). 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. FT. CHARTRES AND IVY LANDING DRAINAGE AND LEVEE DISTRICT NO. 5 AND STRINGTOWN DRAINAGE AND LEVEE DISTRICT NO. 4, ILL. Location. In Monroe and Randolph Counties, Ill. on left bank of the Mississippi River between river miles 130 and 141 above the mouth of the Ohio River. (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 625 of Annual Report for 1958 and page 674 of Annual Report for 1957. Existing project. Project area contains about 18,700 acres protected from floods of the Mississippi River by levees. However, when Mississippi River stage exceeds 15 feet on the St. Louis, Mo., gage, substantial damage has occurred due to blocked interior drainage. The 1965 Flood Control Act provides for construction of three pumping stations to reduce interior flooding. Estimated cost (1971) is $2,600,000. Local cooperation. Local interests must provide lands, easements, and rights-of-way for construction; hold the United States free from damages; maintain and operate the project after completion; rehabilitate Kidd Lake Ditch; and maintain existing ditches to provide unrestricted flow to the pumping stations. Operation and results during fiscal year. Project not yet funded. 14 -3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Condition at end of fiscal year. Work authorized by the Flood Control Acts of 1936 and 1938 is complete. Work authorized by the Flood Control Act of 1965 not yet initiated. 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-D.) Operations and results during fiscal year. Construction and land acquisition continued on Carlyle Lake and Lake Shelbyville. Construction is complete 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 Lake, Lake Shelbyville, New Athens, Vandalia District No. 21, and Dively District No. 23.

(See Corps of Engineers Navigation Charts, Middle and Upper Mississippi River, Cairo, Ill., to Minneapolis, Minn.) 14 -7 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Previous project. For details see Annual Report for 1968. Existing project. Project area contains about 13,700 acres protected from major floods of the Mississippi River by levees. However, when Mississippi River stage exceeds 30 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 seepage from the Mississippi River. The 1965 Flood Control Act provides for a pumping station with collector ditches and necessary appurtenant facilities for removal of water impounded by existing levee. Estimated cost (1971) is $429,000. Local cooperation. Local interests must provide lands, easements, and rights-of-way for construction; hold the United States free from damages due to the construction works; maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of the Army; and prevent encroachment on improved channels or ponding areas and, if ponding areas and capacities are impaired provide substitute storage or equivalent pumping capacity promptly without cost to the United States. Operations and results during fiscal year. Preconstruction planning continued. Condition at end of fiscal year. Construction has not started. 13.

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) $43,568,000, exclusive of amount expended on previous projects; and non-Federal $10,533,300, including $3,118,072 contributed funds and value of useful work performed, $1,343,228 lands, $4,087,000 relocations and $1,985,000 other costs. (See Table 15-B for authorizing legislation.) Local cooperation. Fully complied with except for provisions of Sec. 101 of 1968 River and Harbor Act. Non-Federal contributions estimated at $3,118,072. Terminal facilities. Terminal facilities on Harbor Island at head of Aransas Pass, Ingleside, Corpus Christi, La Quinta, Avery Point, and Viola, are considered adequate for existing commerce. (See Port Series, No. 25, revised 1968, Corps of Engineers.) Operations and results during fiscal year. New Work: Engineering and design and supervision and administration for the 45-foot project cost $26,144 and $5,658.

Repair of directional and information signs, and reference lines by hired labor totaled $1,090. Reimbursement for damages to hopper dredge dock totaled $1,797 credit. (See Table 15-H for dredging operations.) Condition at end of fiscal year. The project is about 47 percent complete exclusive of inactive portions. The Port Aransas-Corpus Christi 40-foot project was initiated in 1963 and completed in 1966. The Jewel Fulton Canal was initiated in 1962 and completed in 1963. The work remaining consists of deepening entrance channel to 47 feet; deepening all other deepdraft channels to 45 feet; widening of channels and basins; constructing a turning point on main channel at junction with La Quinta channel and constructing a mooring area at Port Ingleside with dolphins. Preconstruction planning on 45-foot project is in progress. (See Table 15-E for total cost of existing project to June 30, 1971.) 7. CORPUS CHRISTI SHIP CHANNEL, TEX. (PORT ARANSAS BREAKWATERS) Location. Breakwaters and channel are located at Port Aransas, Texas, which is about 20 miles east from the city of Corpus Christi and 6 miles southeast from Aransas Pass, Texas. Existing project. The plan of improvement provides for the construction of a breakwater at the entrance to the harbor area at Port Aransas, and for the realignment of the existing 12-foot by 100-foot project channel to Port Aransas. The breakwater would consist of two overlapping sections, one on the east side of the realigned entrance channel and having a length of 830 feet, the second to be located on the west side of the entrance channel with a length of 1,290 feet. The channel to Port Aransas would be relocated in the 300-foot clear distance between the overlapping sections. The portion of the channel remaining inside the breakwaters would be widened to 150 feet. Estimated cost for new work is $515,000 Federal (Corps), and $80,325 non-Federal. (See Table 15-B for authorizing legislation.) Local cooperation. Section 107, River and Harbor Act of 1960 applies. In addition, local interests must (1) contribute in cash or in items of equal value, a total sum equal to 50 percent of the total first cost of the general navigation facilities allocated to recreation, exclusive of costs for aids to navigation, lands and damages, and preauthorization surveys. The required cash contribution is estimated at $80,325; the final allocation of costs will be made after the actual costs have been determined. (2) Contribute in cash a share of the cost of Federal maintenance of the general navigation facilities based on the ratio of recreational benefits of the project to total benefits, said share, 15 - 4 GALVESTON, TEX., DISTRICT currently estimated at $700 per annum, to be subject to reappraisal at five-year intervals based on experienced project use and maintenance costs. Terminal facilities. Private and public owned wharves and piers are the only terminal facilities at Port Aransas. Facilities are considered adequate for existing commerce. Operations and results during fiscal year. New Work: Preconstruction planning was initiated during the fiscal year at a cost of $17,717. Condition at end of fiscal year.

Neches River rises 60 miles southeast of Dallas, Tex., and flows generally southeast 416 miles to Sabine Lake 4 miles east of Port Arthur, Tex. Angelina River flows southeast 200 miles to its confluence with Neches River 126 miles above its mouth. Authorized features are located as follows: Rockland Dam on Neches River about 3 miles west of Rockland, Tex.; Sam Rayburn Dam on Angelina River about 10 miles northwest of Jasper, Tex.; Dam A on Neches River about 4 miles west of Horger, Tex.; Town Bluff Dam on Neches River about one-half mile north of Town Bluff, Tex. (See Geological Survey base map, Northeast Texas, scale 1:500,000.) Existing project. Provides for dams and lakes, at Rockland and Sam Rayburn damsites on Neches and Angelina Rivers, respectively, which will give a large measure of flood protection to agricultural lands in lower river valley and to city of Beaumont, Tex., reduce hazards to navigation resulting from floods, and provide a regulated flow in lower river to supply municipal, agricultural, and industrial demands. In addition, these proposed projects will permit development of a large amount of firm power and afford opportunities for recreation. Plan also provides for construction of Dam A, on Neches River below Rockland Dam, for development of power and Town Bluff Dam, below confluence of Angelina and Neches Rivers, to regulate daily fluctuations in discharge from turbines in upper projects and to develop a limited amount of power. Construction of Rockland and Dam A Lakes and power facilities at Town Bluff Dam-B. A. Steinhagen Lake is to be deferred until justified by future conditions. Estimated cost for new work, revised in 1971 for Town Bluff Dam-B. A. Steinhagen Lake and Sam Rayburn Dam and Reservoir and in 1954 for Dam A and Rockland Lakes, is $127,151,000 including $5 million non-Federal cost. (See Table 16-D for flood control works included in comprehensive plan.) 2. TOWN BLUFF DAM-B. A. STEINHAGEN LAKE, TEX. Location. Dam is on Neches River about 12.4 miles below mouth of Angelina River, one-half mile north of Town Bluff, Tex., and 93 river miles north of Beaumont, Tex. Existing project.

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. 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 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 con- * 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. 17 - 1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 tribution 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. Operations and results during fiscal year. Construction continued on Phase 1 of the South Diversion Channel, including relocation of Sandia Base (AEC) Spur Bridge and Kirtland AFB and Industrial Park spur tracks. The Phase 2 South Diversion Channel contract was awarded June 24, 1971. The completed North Diversion Channel prevented an estimated $84,000 annual flood damages during FY 1970. Peak flood flows recorded were: July 15, 1970, 740 c.f.s. (9 acre-feet); July 21, 1970, 1,095 c.f.s. (230 acre-feet); August 5, 1970, 1,970 c.f.s. (230 acre-feet); August 10, 1970, 3,780 c.f.s. (380 acre-feet); and August 13, 1970, 3,050 c.f.s. (240 acre-feet). The estimated total accumulated flood damages prevented through FY 1970 amount to $293,000. Condition at end of fiscal year. Project planning is complete. Construction of the north diversion channel is complete. The South diversion channel construction is about 58 percent complete. Total project is about 88 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 529,000 acre-feet (198,900 for flood control, 259,600 for water conservation and irrigation, and 70,500 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 1970 were $426,000. Estimated irrigation benefits for fiscal year 1970 were $235,200. Estimated total accumulated irrigation benefits through fiscal year 1970 were $5,548,047. Pool elevation at start of fiscal year was 4,193.18 feet, with corresponding storage of 282,121 acre-feet. This was also the maximum pool elevation and storage for the year. Pool elevation did not exceed spillway crest (elevation 4,201 feet) during fiscal year. Irrigation releases were terminated October 15, 1970, and spring irrigation releases began April 1, 1971. Total releases for fiscal year were 102,846 acre-feet (100,296 for irrigation, and 1,550 miscellaneous losses). Releases of 97,519 acre-feet were made to Arch Hurley Conservancy District and 2,777 acre-feet to Bell Ranch. Pool elevation on June 30, 1971, was 4,178.88 feet with corresponding storage of 167,821 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, KANS. 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 grade raise. Appurtenant works include interior drainage structures and fencing, a pumping plant for 17- 2 ALBUQUERQUE, N. MEX., DISTRICT 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. The top of levee profile for 60,000 c.f.s. would increase the floodway capacity so it would not be necessary to raise the bridges on Second Street and 14th Avenue. The bridge crossings would require sandbagging during floods of 60,000 c.f.s. magnitude. 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 such a flow could be safely passed through the floodway as presently designed. Estimated Federal cost is $3,500,000. 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 was approved by the voters October 12, 1965. Formal assurances were received March 25, 1970. Estimated non-Federal cost is $750,000. Operations and results during fiscal year. Preconstruction planning was continued. The cost reimbursable contract with the Chicago Rock Island and Pacific Railroad Company for design of the railroad bridge and grade raise continued. The construction plans and specifications for the channels, canals, levees and floodwalls were initiated. Condition at end offiscalyear. Preconstruction planning is about 93 percent complete. The plans and specifications for the railroad bridge and grade raise are about 90 percent complete. The plans and specifications for the channels, levees and floodwalls are about 8 percent complete. 4. EL PASO, TEX. 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 $19,700,000. (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 ad- 17 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 ditional 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. 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 $4,000,000. Operations and results during fiscal year. Construction was initiated in the Central Area. Construction of portions of the Fort Bliss Sump and Mountain Avenue Outlet Conduits was started in January 1971. Plans and specifications for the roads and utilities relocations and construction of the Northgate and Range Dams and their associated channels and canals were completed. Feature design memoranda for the Pershing System, Sunrise and Mountain Park System and Mckelligon- Fillmore System of the Central Area were initiated. Condition at end offiscalyear. Preconstruction planning is complete. Planning for the Northwest Area has been postponed at the request of the City of El Paso pending completion of their master plan of development for the area. Planning for the copper system of the Southeast Area has also been temporarily suspended. The city requests this postponement until they complete alternate studies to solve this problem. The contract for construction of the Fort Bliss Sump and Mountain Avenue Outlet Conduits (portions) is about 25 percent complete. The overall project completion is about 15 percent. 5. GREAT BEND, KANS. 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 Creel 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 $6,760,000. (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. Formal assurances of local cooperation have not been requested. However, the Mayor and City Council have taken the position that these assurances will be furnished and that requirements will be met when requested. Estimated non-Federal cost is $2,240,000. Operation and results during fiscal year. Project planning has been held in abeyance since defeat of bond issue. No planning work was accomplished during the fiscal year. Condition at end of fiscal year. Preconstruction planning is about 2 percent complete. 6. JOHN MARTIN RESERVOIR PROJECT, 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 118 feet above streambed and an overflow, gated spillway 1,174 feet long. On basis of 1968 sediment resurvey, new area-capacity curves show reservoir storage capacity of 618,700 acre-feet (261,000 for flood control and 17 - 4 ALBUQUERQUE, N. MEX., DISTRICT 357,700 for conservation and recreation storage). Reservoir controls a contributing drainage area of 18,130 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. No flood and sediment damages were prevented during fiscal year 1970. Estimated total flood and sediment damages prevented by project through fiscal year 1970 were $72,380,000. Estimated irrigation benefits for fiscal year 1970 were $573,050. Estimated total accumulative irrigation benefits through fiscal year 1970 were $19,136,779. Maximum pool elevation of 3804.11 feet with corresponding storage of 35,154 acre-feet occurred on March 31, 1971. Total releases for fiscal year were 177,343 acre-feet. Releases attributed to irrigation benefits amounted to 34,529 acre-feet. Reservoir was empty July 1, 1970 - Oct. 8, 1970 and April 19, 1971 - June 30, 1971. Winter storage was in effect from November 1, 1970 until April 19, 1971. 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, 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 9.3 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 $2,590,000. (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 $310,000. Operations and results during fiscal year. Preconstruction planning was continued. Condition at end offiscalyear. Preconstruction planning is about 90 percent complete. 8. LAS CRUCES, N. MEX. 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 Las Cruces Dam which extends across Alameda and Las Cruces Arroyos. The dam will be provided with an uncontrolled outlet and spillway. 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, 17 - 5 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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. Estimated Federal cost is $5,430,000. (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; and prevent encroachment, other than natural sediment deposits, on the reservoir area which would reduce its storage capacity. Estimated non-Federal cost is $1,280,000. Formal request for assurances was transmitted 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 because 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 and was actively pursuing financing of local cooperation requirements and would explore possible sources of revenue and funding. 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. Acquisition of lands and rights-of-way for the Las Cruces Dam has been completed. The City of Las Cruces requested the Campus Dam portion be deleted from the project. The New Mexico State University plans to solve the Campus Arroyo flood problem locally. Operations and results during fiscal year. No work was accomplished pending authorization of construction start. Condition at end offiscalyear. Preconstruction planning is complete. 9. LOS ESTEROS LAKE, 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. (See U.S. Geological Survey map, Corazon, N. Mex.), sheet, scale 1:125,000.) Existing project. Authorized plan of improvement consists of an earth and rock fill dam 1,950 feet long and 212 feet maximum height above the streambed. Project purposes are flood control, irrigation and sediment retention. An unlined, open rock cut about 1,000 feet back from the left abutment serves as an uncontrolled spillway. The outlet works, located in the left abutment, consists of a control tower, intake structure with gates, and a 10 foot diameter concrete tunnel with a terminal flip bucket energy dissipater. An auxiliary earthfill dam 1,310 feet long with a maximum height of 15 feet is located in a saddle depression about 4,000 feet to the left of the main dam abutment. Storage capacity at the spillway crest is 529,000 acre-feet which includes 82,000 sediment storage, 200,000 acre-feet irrigation storage and 247,000 acre-feet flood control storage. Surface area of the reservoir at the spillway crest is 12,294 acres. Contributing drainage area at the damsite is 2,479 square miles. Authorized project also includes modification of the existing Alamogordo Dam and Reservoir on the Pecos River, (river mile 710.8) about 56 miles downstream from Los Esteros Lake. This modification provided for a reservoir capacity of 210,000 acre-feet by raising the dam embankment 10.5 feet and constructing an emergency spillway through the ridge on the right abutment. Changes to the service spillway were to limit the discharge to the capacity of the existing chute spillway and tainters. Project document also reallocated the storage in Alamogordo Dam and Reservoir to exclusive flood control use. Subsequent to project authorization, the Bureau of Reclamation modified the existing structure to its feasible limit without major reconstruction. This modification consisted of raising the dam height 16 feet, altering the existing service spillway to limit the discharge to 56,000 c.f.s., and constructing an uncontrolled emergency spillway in the left abutment. The spillway capacity is 206,000 c.f.s. Storage allocation studies in response to authorizing document provides for transfer of all but 20,000 acre-feet of irrigation storage to Los Esteros Lake with remainder of storage in Alamogordo Reservoir reserved for flood control purpose. This transfer will be done under terms of the Pecos River Compact with consent of the Carlsbad Irrigation District. The estimated Federal (Corps of Engineers) cost for Los Esteros Lake is $15,200,000. (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. 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 17 - 6 ALBUQUERQUE, N. MEX., DISTRICT 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. A memorandum of agreement is to be executed between the Corps of Engineers, U. S. Bureau of Reclamation and Carlsbad Irrigation District for transfer of this irrigation storage from the Alamogordo Reservoir to Los Esteros Lake. Operations and results during fiscal year. The general design memorandum was approved on September 17, 1970. Plans and specifications for construction of the access road (Phase I) were submitted to Southwestern Division in April 1971. Acquisition of required rightsof- way for this road was initiated. The feature design memorandum for the outlet works, embankment, spillway and project buildings was initiated. A draft of the memorandum of agreement was prepared and submitted to higher authority for review and approval. Coordination of this draft with the U. S. Bureau of Reclamation and Carlsbad Irrigation District was also initiated. Condition at end of fiscal year. Preconstruction planning is complete. Initiation of construction is pending formal approval of memorandum of agreement for transfer of irrigation storage. Plans and specifications for construction of the access road (Phase I) are about 95 percent complete. The feature design memorandum for the outlet works, embankment, spillway and project buildings is about 5 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-C 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.

Reservoir has a capacity of 111,698 acre-feet (73,000 acre-feet for flood control and 38,698 acre-feet for sediment control). 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.) Operations and results during fiscal year. Ordinary maintenance and operation continued. Reservoir was empty on July 1, 1970, and remained empty most of the fiscal year except for short periods of sediment control storage during July, August, September, and October 1970. There was no flood control regulation for the 17 - 8 ALBUQUERQUE, N. MEX., DISTRICT fiscal year. The maximum pool elevation was 5,148.70 on August 2, 1970, with a corresponding storage of 247 acre-feet. Estimated total accumulated flood and sediment damages prevented by project through fiscal year 1970 were $1,690,000. 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-rehabilitat on 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-D 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 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 1970 amounted to $860,000. 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 95 percent complete. 11. TRINIDAD LAKE, 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 $33,700,000 (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 $9,768,000 (1971 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 irrigators) 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 17- 9 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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. Real estate acquisition continued. Construction of outlet works was completed on December 30, 1970, except for operation and maintenance work. Contract for cemetary relocation was awarded on August 7, 1970 and completed on November 3, 1970. The Phase I relocation of the county road was started on January 14, 1971. A contract for site preparation in the reservoir and dam area was awarded on May 25, 1971. Plans and specifications for construction of the city water line relocation, Colorado and Wyoming Railroad relocation, Embankment, Spillway and Access Road were completed and submitted to Southwestern Division on December 31, 1970. Plans and specifications for relocation of the Jansen Water Supply reservoir were approved on December 31, 1970. Work continued on the cost reimbursable contracts for relocation of Colorado State Highway No. 12, powerlines and telephone lines. Design memorandum for the reservoir clearing was initiated. Condition at end of year. Land acquisition is essentially complete. The controlled outlet works are complete except for some operation and maintenance work. The cemetary relocation is complete. The relocation of the county road (Phase I) is about 93 percent complete. The site preparation contract is about 10 percent complete. Plans and specifications for the railroad and city water supply line relocation were given conditional approval by Division Engineer, Southwestern Division, on Dec 31, 1970 pending final approval by the Colorado and Wyoming Railroad Company. The railroad ownership changed in the third quarter. The new owners are still reviewing the relocation plans and specifications. The cost reimbursable agreements are expected to be finalized early in FY 1972 for relocation of the powerlines, telephone lines and Colorado State Highway No. 12. Overall project completion is estimated at 33 percent. 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 34 and Rocky Dam on Rocky Arroyo at about river mile 10, which will form Two Rivers Reservoir. Diamond "A" Dam is 98 feet high and 4,885 feet long and Rocky Dam is 118 feet high and 2,940 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 about 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, 1970. No flood storage during the fiscal year. The peak mean daily inflow was 111 c.f.s. on 17 - 10 ALBUQUERQUE, N. MEX., DISTRICT August 11, 1970. Estimated total accumulated flood damages prevented through fiscal year 1970 were $1,382,000. Condition at end of fiscal year. Project is complete and was placed in operation July 1963. 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 $5,947 and total cost to June 30, 1971, was $46,877. 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 the start of the fiscal year was 4,946.0 feet with a corresponding storage of 4,000 acrefeet. There was no change until September 6, 1970, when storage was increased for flood control purposes. By September 15 the reservoir elevation had risen to 9,961:3, a storage of 9,400 acre-feet. This was the maximum storage for the year. Storage remained at this elevation until November 1, 1970, when transfer of excess storage to Elephant Butte Reservoir was begun. Storage was reduced to 2,900 acre-feet at elevation 9,942.0 feet by November 11 when operation of Platoro Dam was suspended for the winter. Storage increased during the unattended period and by April 28, 1971, the pool elevation was 9,958.5 feet with a storage of 8,300 acre-feet. Storage remained at this elevation until June 4 when the elevation dropped to 9,958.4 with a storage of 8,250 acre-feet. Storage remained at this elevation for the rest of the fiscal year. The maximum release for the fiscal year was 565 c.f.s. on June 16, 1971. A flow of 2,200 c.f.s. occurred in the Conejos River at Mogote, Colorado, on September 14, 1970. Without regulation by Platoro Reservoir, the flow would have been 3,200 c.f.s. On September 6, 1970, a peak of 1,140 c.f.s. was recorded at Mogote without Platoro Reservoir, the peak would have been 2,400 c.f.s. Estimated total accumulated flood damages prevented by project through fiscal year 1970 were $629,000. Fiscal year costs were $2,738, and total costs toJune 30, 1971, were $45,230. 15. OTHER AUTHORIZED FLOOD CONTROL PROJECTS See table 17-E. 16. PREAUTHORIZATION STUDIES IN INTEREST OF POTENTIAL PROJECTS Flood control activities pursuant to section 205, Public Law 685, 84th Congress, as amended (preauthorization).

Provides for improvement of Arkansas River Basin by construction of coordinated developments for navigation, hydroelectric power, flood control, water supply, sediment control, recreation, and fish and wildlife propagation. McClellan-Kerr Arkansas River Navigation System provides a channel 9 feet deep and 441.0 miles long, beginning at mouth of White River, which enters Mississippi River 599 miles above Head of Passes, La., thence 10 miles upstream to mouth of Wild Goose Bayou; thence 9 miles by a land cut, designated as Arkansas Post Canal to mile 42 (1943 survey) on Arkansas River; thence 372.3 miles along channel of latter stream to mouth of Verdigris River at navigation mile 391.3; thence 49.7 miles up Verdigris River to head of navigation at Catoosa, Okla. Waterway is canalized throughout its length by 17 locks and dams with total lift of 420 feet. Dardanelle, Ozark, Robert S. Kerr, and Webbers Falls are multiple-purpose projects including power. Lock chambers are 110 by 600 feet. A minimum channel width of 150 feet is provided for Verdigris River, 250 feet for Arkansas River, and 300 feet for Arkansas Post Canal and White River. Other coordinated developments consist of 15 lakes, of which 13 are in Tulsa District, Kansas and Oklahoma, and 2 in Little Rock District. Pertinent data and estimated Federal cost are summarized in tables 18-C and 18-D, McClellan-Kerr Arkansas River Navigation System and Lakes, at end of chapter.

None. Operation and results during fiscal year. Regular funds, new work: Design was continued for additional recreation facilities. Regular funds, maintenance: Resurfacing of the powerhouse access road was completed. Design studies continued for road improvements and spillway repair. Construction of 29 houses and chapel was completed. Contract for resurfacing embankment toe road initiated. Fort Peck Lake was operated in conjunction with the other Missouri River reservoirs for flood control, navigation, power production, and other multiple-purpose uses. Reservoir releases amounted to approximately 9,776,000 acre-feet, or an average discharge of 13,500 cubic feet per second. Generating facilities produced 1,630,480,000 kilowatt-hours of electricity. Total cost of Operation and Maintenance during the Fiscal Year was $2,546,300, however, reimbursement from the Bureau of Reclamation for the pro rata share cost of Operation and Maintenance of the powerplant, reimbursement for furnishing operators' village facilities, and property disposals reduced net cost to $1,505,900. Condition at end of fiscal year. Work started on original project in October 1933 and on second power plant in August 1956. The project is complete. Additional recreational facilities are being constructed utilizing Code 710 funds. On 30 June 1971, the pool was at elevation 2243.5 and 17,585,000 acre-feet of water was impounded in the reservoir. 2. MISSOURI RIVER, SIOUX CITY, IOWA TO RULO, NEBR. Location. Jefferson, Madison, and Gallatin Rivers conjoin at Three Forks, Mont., to form Missouri River, which flows southeasterly 2,315.1 miles (1960 mileage) across or along seven states to Mississippi River, 17 miles above St. Louis. River is boundary between states of Missouri, Kansas, Nebraska, and Iowa. For description see page 1149, Annual Report for 1932. Previous projects. For details see page 1893, Annual Report for 1915, and page 1175, Annual Report for 1938. Existing Project. Provides for a channel of 9-foot depth and width not less than 300 feet, to be obtained by revetment of banks, construction of rock dikes to contract and stabilize waterway, cutoffs to eliminate long bends, closing minor channels, removal of snags and dredging as required. Estimated cost of new work Sioux City to Rulo, Nebr. (July 1971) is $193,050,000, exclusive of amounts expended on previous projects. (See table 21-C for authorizing legislation, and table 21-E for Terminal Facilities.) Operations and results during fiscal year. Regular Funds, New Work: Consisted of construction, by contract, of 5,867 linear feet of dikes and 11,835 linear feet of stone fill revetments; construction of one river site recreational area and initiated and completed; no new work construction was accomplished with hired labor forces. Regular Funds, Maintenance: Consisted of construction, by contract, of restoring and replacement of 21,021 linear feet of dikes and 192,320 linear feet of stone fill revetments. Work by hired labor forces consisted of removal of 79,035 cubic yards of point removal for channel correction; 35,686 tons of stone was salvaged from obsolete structures and used to repair 11,895 linear feet of dikes and revetments and 54,175 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 1975 for Bank Stabilization and fiscal year 1976 for the Recreation Feature. The work was approximately 93.8 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. Seven 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, 1971.) 3. OTHER AUTHORIZED NAVIGATION PROJECTS See table 21-D. FLOOD CONTROL 4. BEAR CREEK LAKE, COLO. Location. Damsite is on Bear Creek in Jefferson County, Colorado about 8 miles above the confluence of Bear Creek with the South Platte River at Denver. Existing project. Project consists of an earthfill dam 185 feet high, with a crest length of about 5,000 feet, and a supplementary earthfill dike with a height of 85 feet and a crest length of 2,000 feet, to the south of the main dam, and an uncontrolled earth and rock-cut emergency spillway. The lake will provide storage capacity of 24,290 acre-feet for flood control and 2,000 acre-feet for sediment and recreation. Authorized by 21 -2 OMAHA, NEBR., DISTRICT 1968 Flood Control Act (Senate Document 87, 90th Congress). Estimated cost is $53,000,000 (July 1971) of which $2,860,000 is future non-Federal reimbursement for recreation cost sharing. Other non-Federal costs, for acquisition of water for recreation pool, are estimated at $440,000. 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. Design studies continued by hired labor. Condition at end offiscalyear. Advance Engineering and Design studies in progress. General Design Memorandum approximately 85 percent complete. 5. 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 channeldownstream 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 $4,272,000 (July 1971), of which $4,045,000 is Federal cost and $227,000 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. Preparation of the General Design Memorandum initiated. Condition at end of fiscal year. General Design Memorandum was about 10 percent complete. 6. 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.).

IMPROVEMENTS Navigation Page 1. Construction of locks and dams on Ohio River ..................................... 22-1 2. Navigation (cont.) Page Open channel work, Ohio River ........ 22-3 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, Cannelton, 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, and 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. 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) (1971), exclusive of Gallipolis locks and dam reported under Kanawha River project is $1,385,036,909, estimated non-Federal cost is $9,348,000. 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, 1935 Act, and constructed under project for improving lower Kanawha River. Locks and dams 7, 8, and 9 were replaced by New Cumberland locks and dam, locks and dams 10 and 11 were replaced by Pike Island locks and dam, locks and dams 18, 19 and 20 were replaced by Belleville locks and dam, locks and dams 21, 22 and 23 were replaced by Racine locks and dam, locks and dams 27, 28, 29, and 30 were replaced by Greenup locks and dam, locks and dams 31, 32, 33, and 34 were * All cost and financial statements for projects are listed at the end of this chapter.

Costs were $2,798,780 for Pittsburgh District, $3,229,089 for Huntington District and $4,345,525 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 22-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 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 22-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 Splacing 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 22-E for authorizing legislation. Local cooperation. River and Harbor Act of January 21, 1927, authorizing construction of ice piers for 22 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 general open channel work, imposes condition that before work is begun on any pier, local interests convey to the United States free of cost such riparian rights as may be deemed necessary in connection with the improvement at 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 navigatioh 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 $726,232. Dredging by hired labor: Huntington District 359,733 cubic yards at $128,871 and Louisville District, 4,112,822 cubic yards at $855,593. 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. 22 - 4 OHIO RIVER TABLE 22-A COST AND FINANCIAL STATEMENT See Section Total to in Text Project Funding FY68 FY69 FY70 FY71 June 30, 1971 1.

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: For information concerning construction of locks and dams A, B, C, D, E and F, required dredging and related costs to secure 6 foot navigation, see pages 1069 and 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 as Kuttawa (Eureka), Dover, and Cheatham, to replace existing locks A to F inclusive below Nashville and lock 1 above Nashville. (See paragraph 23-B for authorizing legislation.) Subsequent authorities provided for construction of hydroelectric power-generating facilities at Cheatham Dam, river mile 148.7, 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 multiple-purpose improvement consisting of a dam, lock, and powerplant near mile 30.6 on lower Cumberland River and a canal for navigation and other purposes connecting this 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, permits 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. * 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. 23 - 1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Estimated cost of modified project for 9-foot navigation and multiple-purpose development is $176,195,300 (July 1971). (See table 23-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: See pages 1693 thru 1696 of Annual Report for 1950 for information including statistical data on locks and dams 1 to 17 and 21. Completion information is shown on pages 1454 of the report for 1951. See Table 23-B for Authorizing Legislation. 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 $127,435,100 (July 1971). Estimated cost of Celina Dam (1959) is $39,100,000. (See table 23-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 23-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. There are 32 terminals on the Cumberland River (1 municipally owned and open for public use; 2 government owned facilities and 29 privately owned facilities). A total of 21 terminals have railroad connections. Principal commodities handled are petroleum products, sand, gravel and chemicals. Seven terminals are set up to handle various types of commodities. Facilities considered adequate for existing commerce. For further information see page 695 of Annual Report for 1969. Operations and results during fiscal year. New work: Below Nashville: Sewerage improvements for right and left banks of Cheatham project were completed during FY 1971. Also, construction of comfort station on right bank was contracted near end of the fiscal year. Construction of comfort stations, washhouses and related facilities at four sites, Barkley Project, was accomplished under contract. Miscellaneous items of work under various features 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 $743,701. Above Nashville: Contracts for construction oft comfort stations, washhouses and related facilities at Cages Bend and Bledsoe Creek sites, Old Hickory project, were awarded during FY 1971 and scheduled for completion in FY 1972. Construction of the powerplant at Cordell Hull project was continued. Plans and specifications for phase II clearing were approved and contract for this work was awarded. Work covering part II of road relocations in Jackson County portion of reservoir was awarded during 4th quarter of the report period. Supply contracts completed with exception of erecting engineers services include governors, 13.8 kv switchgear, 161 kv disconnect and insulators.

Also, replacing lighting'transformers and extending power circuits at Cheatham were continued. Work at Old Hickory project involves completion of repairs to lock valves, improvement to warehouse storage facilities was continued and provision for additional storage bays was initiated. Temporary maintenance was continued as necessary at Cordell Hull lock 23 - 2 NASHVILLE, TENN., DISTRICT pending placement in permanent operation. Operation of powerplants was continuous except for normal interruptions and necessary shutdowns for inspection, repair and maintenance purposes. Total net energy generated at Barkley Dam (681,522,020 kwhr) 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 (201,467,370 kw-hr) and Old Hickory Dam (546,213,380 kw-hr) was made available for distribution. Power revenues were $1,940,545, $873,245, and $1,649,464, respectively. Benefits attributable to Barkley effect in reduction of flood flows on Cumberland and lower Ohio and Mississippi River during year are estimated as $385,700. 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: Construction of Cheatham lock and dam was completed in November 1960. See page 1078 of 1962 Annual Report for chronology of construction. Acquisition for Barkley project includes 70,549 acres in fee, 24,327 acres in easements and 7,339 acres under use permit; project 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. Work remaining consists mainly of construction of recreation facilities. Total new work costs for this section to June 30, 1971, were $179,219,379 including $685,000 public works funds. Above Nashville: 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, was inundated with partial impoundment of Cordell Hull Reservoir which, upon project completion, will extend the 9-foot waterway to Celina, river mile 380.8. Old Hickory project was completed for full beneficial use December 1957 w]th placement of last power unit in commercial operation. Further details are given on page 1080 of Annual Report for 1962. Construction of Cordell Hull project, started May 1963, is 76 percent complete, see "New Work above Nashville", for detail of work currently underway. Total lands acquired 26,294 acres (26,008 in fee and 286 acres in easements), represent 96 percent of project requirements. Total new work costs for this section to June 30, 1971, were $108,250,186. Operation and maintenance of structures: Barkley, Cheatham, and Old Hickory locks were in operation at end of year; structures, channels, and appurtenances were maintained in serviceable condition.

Formed by junction of French Broad and Holston Rivers in eastern Tennessee, 4.4 miles above Gay Street Bridge at Knoxville, flows southwest into northern Alabama, thence in a generally westerly course across north Alabama, to northeast boundary of Mississippi, thence nearly due north across Tennessee and Kentucky, entering Ohio River at Paducah, 652.1 miles from junction of French Broad and Holston Rivers. (See Geological survey base map of Tennessee River Basin.) Previous projects. For details see pages 1902-1906, Annual Report for 1915; pages 1190-1194, 1196-1216, and 1220-1222, Annual Report for 1929; and page 1216, Annual Report for 1938. Existing project. Originally provided for permanent improvement of river for a navigable depth of 9 feet at low water from mouth about 650 miles to Knoxville, Tenn. Only work performed by the Corps was construction of lock at General Joe Wheeler Dam and miscellaneous appurtenant improvements at a new work cost of $2,244,236. Tennessee Valley Authority program provided for obtaining authorized 9-foot project by construction of high dams and locks and utilization of certain locks and dams previously constructed under jurisdiction of the Corps. (See Table 23-B for Authorizing Legislation.) Subsequent construction by that agency of Melton Hill Dam extends navigable channel of Tennessee River system up the Clinch River about 38 miles above damsite (mile 23.1) to vicinity of Clinton, Tenn. (See table 23-D on Tennessee River.) In accordance with general navigation laws placing control and supervision over navigable waters under direction of Secretary of the Army, Corps of Engineers operates and maintains all locks, and maintains navigation channels and safety harbors by performing all necessary maintenance dredging and snagging operations. For information concerning other functions of the Corps under division of responsibilities for Tennessee River since adoption of Tennessee Valley Authority Act of 1933, see page 1084 of Annual Report for 1962. Local cooperation. Authorization requires no local cooperation in construction of alternate system of low dams. It does, however, provide that if high dams are 23 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 built before the United States builds projected locks and low dams which are to be replaced, the United States shall contribute to cost of substituted structures an amount equal to estimated cost of works of navigation for which substitution is made. Terminal facilities. There are 132 terminals on the Tennessee River (5 municipally or state owned, 13 government owned facilities and 114 privately owned facilities). A total of 79 terminals have railroad connections. Principal commodities handled are petroleum products, sand, gravel, coal, coke, grain, chemicals, iron, steel, ore and minerals. Twenty-eight terminals are set up to handle various types of commodities. Facilities considered adequate for existing commerce. For further information see page 698 of Annual Report for 1969. Operations and results during fiscal year.

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 financial difficulty on part of city stemming from inability to sell the bond issue at prescribed interest rate.

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 privately 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 $640,911 maintenance repairs at locks and dams were accomplished at cost of $237,893. 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 drainage basins; 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 piovision 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 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 osts of such retaining works; hold and save the United 'tates 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 26 - 2 PITTSBURGH, PA., DISTRICT 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 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 has been terminated and future planning confined to the Grand River Reservoir. The completion of the reanalysis study of Grand River Reservoir's design and operation to make maximum provision of municipal and industrial water supply storage, water quality control and other water resource purposes in absence of any requirements for navigation is being held in abeyance until results of studies of Northeast Ohio Water Development Plan are known. 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 by end of calendar year 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 vaising 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 (1971), exclusive of amounts expended on previous projects is $122,500,000. (See tables 26-B, 26- D, and 26-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: Administrative work in connection with settlements on outstanding judgments on land acquired by condemnation continued at cost of $2,524. Total cost for Maxwell locks and dam was $3,720. Reconstruction of dam 4: Costs incurred in connection with acquisition of flowage easements amounted to $16,944. Total cost for reconstruction of dam 4 was $17,641. Opekiska lock and dam: Final five tracts of land authorized for acquisition were acquired at cost of $1,810. Total cost for Opekiska lock and dam was $4,052. 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 $1,642,131; maintenance repairs at locks and dams, including maintenance dredging in pool 3 and the bar at George's Creek, Maxwell pool, cost $537,675. Study for replacement of locks and dams for lower reach of the river is approximately 27 percent complete. 26 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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.

On December 23, 1970 the reservoir reached year-high elevation of 1114.4, with a storage of 149,900 acre-feet or 50 percent of usable seasonal flood control storage. This elevation was the highest for December in 32 years of operation. The crest reductions effected by this reservoir ranged from 4.9 feet at Maxwell locks and dam to 1.6 feet at lock 2, and 2.0 feet at Pittsburgh. The crest stage on the Ohio River at Pittsburgh on the 23rd was 18.7 feet, 0.7 foot above damage stage. Estimated flood control benefits achieved by this reservoir for fiscal year were $137,000. Total flood control benefits for this reservoir through June 30, 1971 are $98,756,000. Some reservoir management activity was continued comprising sanitation measures, real estate management and operation and maintenance of public-use facilities. This work was limited in scope as State of West Virginia has jurisdiction over recreation in reservoir area. Condition at end of fiscal year. Authorized project is complete. Reservoir is in operation for low water control in Monongahela River and for purpose of flood protection in Monongahela and Ohio Valleys. Construction of dam was started in 1935 and placed in operation in 1938. 7. YOUGHIOGHENY RIVER, PA. AND MD. Location. This river, principal tributary of Monongahela, rises in Preston County, W.

In Cass County, North Dakota, the Lower Branch Rush River rises about 5 miles southwest of Amenia, N. Dak., and flows in an easterly direction. The river, formerly a tributary of the Rush River, was diverted in 1924 and now flows into the Sheyenne 27 - 12 ST. PAUL, MINN., DISTRICT River. (For general location see Geological Survey map of North Dakota.) Existing project. Project consists of enlarging and straightening the channel of the Lower Branch Rush River between mile 17.3 and the confluence with the Sheyenne River. A southern tributary of the Lower Branch will also be enlarged and straightened in the reach from mile 7.5 to the mouth. The existing enlarged Rush River channel will be extended upstream about one-half mile by means of two channel cutoffs to reduce Rush River stages. The project includes bridge and culvert alterations, new bridges, and construction of continuous spoil banks along the downstream 5.4-mile reach of the improved Lower Branch channel. Total project costs (September 1970) for new work are estimated at $1,325,000, of which $1,000,000 is Federal and $325,000 is non-Federal. Project was authorized by the Chief of Engineers on March 5, 1971 under the authority contained in section 205 of the 1948 Flood Control Act, as amended. Local cooperation. Local interests are required to provide without cost to the United States all lands, easements, and rights-of-way necessary for the construction and subsequent maintenance of the project, when and as required; hold and save the United States free from damages due to the construction of the project; maintain all of the project works in accordance with regulations prescribed by the Secretary of the Army; provide without cost to the United States all alterations and relocations of existing improvements including bridges, bridge approaches, utilities, and other facilities which may be required because of the project; prevent encroachments which would reduce the flood-carrying capacity of the improved channels; provide all associated on-farm drainage works; and assume full responsibility for all project costs in excess of the Federal cost limitation of $1 million. Formal assurances of local cooperation have not been requested. The Rush River Flood Control District has agreed to sponsor the project and meet local cooperation requirements.with the assistance of the Cass County Board of Commissioners who have agreed to assume the costs of road and bridge changes.

Along Minnesota River between miles 103.5 and 109.5 near Mankato, North Mankato, and Le Hillier, in south-central Minnesota. For general location see Geological Survey map of Minnesota.) Existing project. As modified as a result of severe 1965 flood, provides for protection of communities of Mankato, North Mankato, and Le Hillier by means of levees and floodwalls with pumping plants and interior drainage facilities. See page 1090 of Annual Report for 1967 for further details. Estimated Federal cost (1971) for new work is $16,000,000. Project was authorized by 1958 Flood Control Act (H. Doc. 437, 84th Cong., 2d sess., contains latest published map). Project was modified by 1965 Flood Control Act. Local cooperation. Local interests must furnish lands and rights-of-way for construction of project, hold the United States free from damages, maintain and operate works after completion, make necessary changes to utilities, highways, and bridges including approaches, prevent encroachment on ponding areas and existing river channels, use the three pumps in existing Indian Creek pumping station, remove remaining portion of Blue Earth River dam, and contribute in cash or equivalent construction work 1.9 percent of gross Federal first cost, presently estimated to be $304,000. Section 207, 1965 Flood Control Act, modified requirements of local cooperation to credit local interests against the required contribution for work done by them during 1965 high water period. Local interests have expended about $527,360 in such work. Resolutions agreeing to provide formal assurances of local cooperation, when requested, were passed by the city council of North Mankato, Mankato, and South Bend Township (Le Hillier), respectively, on November 12, 1968. Operations and results during fiscal year. A contract for construction of a segment of work at the upstream end of stage I in North Mankato was awarded in August 1970. Contractor earnings for the year were $117,537. An agreement was negotiated in February 1971 with the Minnesota Department of Highways wherein it agreed to install on a cost-reimbursable basis a portion of the stage I, North Mankato interior drainage facilities as part of a highway realignment project, but work was not initiated. Plans and specifications were completed and a contract subsequently awarded in April 1971 for remaining Stage I North Mankato construction from the upstream segment downstream to Monroe Avenue. Work was initiated at a cost of $60,825. Value engineering cost $4,156. Preparation of detailed designs for improvements at Mankato along the Blue Earth River and at Le Hillier was continued. Engineering and design and supervision and administration cost $277,166. Condition at end of fiscal year. Work on detailed plans virtually completed was suspended in 1962 due to lack of local cooperation. Following the record flood in 1965, work was resumed. General Design Memorandum and Supplements 1 and 2 are completed. Supplement No. 2 provides for construction of local protective works in four stages. Detailed designs and plans and specifications are complete for Stage I construction at North Mankato, and construction by 27 - 13 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 contract is under way. Detailed planning for remaining features is in progress. 35. MINOT, N. DAK. Location. In Ward County in northwestern North Dakota on the Souris River, extending from Burlington through Minot to the village of Logan. The river meanders through Minot, flowing generally from west to east and divides the community into two parts. Existing project. Project provides for channel improvement within a 37.0-mile reach of the Souris River extending from Burlington to Logan. The authorized plan for channel improvement includes 18.4 miles of snagging and clearing with nine cutoffs to the downstream end of Minot (27th Street Bridge), 7.3 miles of continuous channel enlargement with five cutoffs below 27th Street, and 2.4 miles of snagging and clearing with three cutoffs downstream to Logan. The cutoffs would shorten the existing channel about 8.9 miles within the improved reach. Low flanking levees totaling about 8,700 feet in length would be required along four reaches above and through Minot. Field experience gathered during the successful flood fight conducted during the flood of May 1970 indicated that several design features are inadequate. A major inadequacy is in the interior drainage feature. The experienced seepage into low areas near the channel together with snowmelt and rainfall runoff indicated that four permanent pumping stations plus storm drain outfall closures would be necessary. Flood experience also indicated that diversion structures and additional bank protection would be required at four locations, and an additional 7,000 feet of channel improvements plus modification of 12,000 feet of low levees would be required in selected reaches. Estimated Federal cost (1971) for new work is $6,960,000. Project was authorized in 1970 under section 201 of the Flood Control Act of 1965 (H. Doc. 91-321, 91st Cong., 1st sess., contains latest published map). Resolutions were adopted by the Public Works Committees of the Senate on June 25, 1970 and the House on July 14, 1970. Local cooperation. Local interests are required to provide without cost to the United States all lands, easements, and rights-of-way necessary for construction and subsequent maintenance of the channel improvement; hold and save the United States free from damages due to construction; maintain and operate all of the works for the channel improvement after completion; accomplish without cost to the United States all necessary changes to buildings, highway bridges (including approaches), streets, dams, sewkrs, and utilities as required for construction of the channel improvement; prescribe and enforce regulations to prevent encroachment on downstream channel capacities for regulation of the reservoirs; and, if improved drainage channel capacities and ponding areas for interior drainage are impaired, provide substitute storage capacity or equivalent pumping capacity promptly without cost to the United States; at least annually inform affected interests that the project will not provide complete flood protection; provide guidance and leadership in preventing unwise future development of the floodplain by use of appropriate floodplain management techniques to reduce flood losses from the Burlington damsite downstream to the New Prairie-Sundre Township line near Logan; adjust all water rights claims resulting from the construction and operation of the project; and hold and save the United States free from damages due to such claims. The Minot City Council on April 5, 1971 and the Ward County Commissioners on May 19, 1971 provided necessary subassurances of local cooperation to the Ward County Water Management Board. On May 26, 1971 the Ward County Management Board approved the motion to provide assurances of local cooperation and the resolution was furnished by letter dated June 16, 1971. Operations and results during fiscal year. An architectengineer contract for aerial topographic surveys was awarded in October 1970 and completed in January 1971 at a cost of $17,363. A second architect-engineer contract for preparation of the design memorandum was awarded in December 1970. Contract work was divided into two phases. The first phase for a project formulation study together with preliminary cost estimates was completed in June 1971 at a cost of $200,000. The second phase is scheduled for completion in 1972. Detail planning was initiated and contract plans and specifications were prepared by hired labor for construction of Roosevelt Park Cutoff improvement, scheduled for award in fiscal year 1972. Engineering and design by hired labor cost $72,370; administration costs were $8,229. Condition at end of fiscal year.

Status: The State of Illinois is the local sponsor for the project. Formal assurances were requested on 22 January 1971. Assurances were received on 26 May 1971. However, a supplement to the assurances must be obtained. Operations and results during the fiscal year. A contract for photogrammetric engineering and field control surveys for the Friends Creek and Greenbelt areas was awarded in March 1971 and was approximately 45 percent complete at the end of the fiscal year. In-house effort was primarily concerned with studying the possibility of using wells as an alternate source of water for Decatur and preparing a litigation report in answer to a civil suit filed against the project. The suit (No. 248-71) was filed in the United States District Court for the District of Columbia on 28 January 191 by the Environmental Defense Fund, Setauket, New York; The Committee on Allerton Park, Champaign, Illinois; Piatt County Board of Commissioners, Piatt County, Illinois; et al against Stanley L. Resor, former Secretary of the Army; Frederick B. Clarke, Chief of Engineers; and the Corps of Engineers. The plaintiffs are seeking injunctive and declaratory relief to restrain the defendants from undertaking land purchases, site preparation, development, construction, or other activities relating to the Oakley project. The District Court for the District of Columbia has rendered no decision as of the end of FY 1971. An under-seepage model study for the Oakley dam foundation was initiated with the Waterways Experimental Station in September 1970. The Secretary of the Army submitted Chicago District report dated May 1970 on the State of Illinois alternative plan to the Chairmen, Committees on Appropriations and Committees on Public Works, United States Senate and House of Representatives on 7 December 1970. The report was printed for use by the Committee on Public Works, United States Senate under date December 1970 and is numbered Serial No. 92-2 (92nd Congress, 1st Session). Engineering costs during the fiscal year were $350,264. In addition there were costs of $6,845 for acquisition of land, and $37,172 for supervision and administration. Total fiscal year costs for project are $394,281. Condition at the end of fiscal year. Planning and acquisition of land are in progress. 30. PEORIA, ILLINOIS Location.

Reports were. started on the results of the following discharge measurements: 1971, New York State Barge Canal at Tonowanda; 1971, American Falls Channel using flurescent dye; 1971, St. Marys River Control Structure for partial gate openings; 1971, St. Clair River using moving boat technique and test of feasibility for application of fluorescent dye in large channels; 1971, investigation of proposed cableway sites in lower Niagara River above Moses powerhouse, and tests for seapage through fill at Crooked River lock using fluorescent dye. For the most part, the aforementioned field work was conducted cooperatively with the Water Survey of Canada, and was required for the International Joint Commission Boards and Committees. In an effort to develop measuring techniques under channel ice conditions, the moving boat technique of measurement and fluorescent dye methods were tested through the ice cover. Improvements of instrumentation for collecting field observations started in FY 70 was completed. This consists of an electronic system developed and constructed by the Waterways Experiment Station for collecting and recording on magnetic tape nine current meter impulses, flow direction, water temperature, air temperature, barometric pressure, wind speed and direction. This development will allow the field data recorded on magnetic tape to be directly fed into the computer for data reduction and analysis. Tests of the system and manuals for operation and maintenance are being prepared. Advances in computer application for collection and processing of field data consisted of development and application of the following programs: plots of cross sections from sounding gage rolls, discharge measurements from moving boat technique, and the computation of the transverse velocity coefficient for each discharge measurement. Regulatory Work Subcommittee: The Detroit District participated in the 1970-71 winter test program for increasing the flow in the St. Marys River under ice conditions. Preliminary cost curves for channel capacity increases and decreases required for the channel designs of the St. Clair and Detroit Rivers were completed as part of the Subcommittee's responsibilities in the Great Lakes Levels Board studies on the regulation of the Great Lakes. These channel design studies including the use of the mathematical models constituted the major effort during the year. Some of the other significant studies completed were as follows: The design and operation of the St. Clair and Detroit River mathematical model, effects of hypothetical saw-toothed fill in the Upper Niagara River, determination of the critical depth profile for the Niagara River, determination of the St. Clair and Detroit River water surface profile for 1923-1933 channel conditions, derivation of St. Marys River Kinetic Energy coefficient, revision of the 1959-1966 discharge measurements based on vertical velocity coefficients, report on Flow Distribution around Cornwall Island for the St. Lawrence Seaway Development Corporation, report on Chicago Sanitary and Ship Canal Discharge Measurements at Willow Springs for the Metropolitan Sanitary Districts of Greater Chicago. This study was undertaken for the purpose- of calibrating the sanitary District's newly installed Westinghouse sonic, leading edge flow meter. The major field activity during this fiscal year consisted of the ice surveillance program on the St. Clair, Detroit, and St. Marys River in response to the Navigation Season Extension. The program included field observations of ice effects on shore structures, flow distribution, water surface profiles and aerial surveillance including photographs and real-time information to the District Engineer during critical ice conditions. A report on those activities was begun. A field program for the study of ship speeds and their effects on shore properties was started. This study conducted jointly with the Canadian St. Lawrence Seaway Authority, was instituted in order to determine allowable coordinated ship speeds along the St. Clair- Detroit River waterway. In addition to the aforementioned, the following studies were completed: Preliminary revision to St. 31 - 26 DETROIT, MICH., DISTRICT Marys River rating of the Control Structure for 16 gates open, effects of St. Marys River Control Structure gate changes on the river profile, and the evaluation of hydraulic studies for the International Niagara Board of Control.

On south shore of Lake Erie, at mouth of Ashtabula River, 59 miles easterly from Cleveland, Ohio. (See Lake Survey Chart 342.) Previous projects. For details see page 1963 of Annual Report for 1915, and page 1593 of Annual Report for 1938. Existing project. For description see pages 1297-99 of Annual Report for 1966. Actual costs for new work for completed portion of project were $11,115,147. Removal of 250 feet of inner breakwater as authorized by 1937 act, at an estimated cost of $128,000 (July 1954) and deepening triangular-shaped harbor area adjacent thereto, as authorized by 1960 act, at estimated cost of $427,000 (Feb. 1961), are deferred for restudy and are excluded from foregoing estimate. Non-Federal costs of $5,696,000 were incurred for construction of access roads, docks, storage and handling facilities and dockside dredging. See Table 32-B for authorizing legislation. Local cooperation. Fully complied with. Terminal facilities. There are 27 piers and wharves, two are owned by city of Ashtabula and Coast Guard. Twenty-one facilities are along banks of Ashtabula River and six are on south side of outer harbor. Twenty-two terminals have railroad connections and 15 mechanical-handling facilities. Facilities are considered adequate for existing commerce. (See Port Series No. 42, revised 1960, Corps of Engineers.) Operations and results during fiscal year. Maintenance: Miscellaneous inspection services and condition surveys by Government plant and hired labor cost $16,820. U. S. Hopper Dredge Lyman removed 107,584 cubic yards, bin measure, of shoaled material over an area of approximately 170,000 square yards of the outer harbor, and lower river entrance channel to project depths of 28, and 27 feet at a cost of $97,085. U. S. Derrick Boat BD 6634 repaired approximately 300 l.f. of the east and west breakwaters, rubblemound construction, at a cost of $145,525. Condition at end of fiscal year. Existing project is about 95 percent complete. West breakwater was completed in 1915 except 580 feet of inner end which was completed in 1923, and 600 feet of outer end which was completed in 1935. East breakwater was completed in 1915; 800 feet of westerly end was removed and a lakeward extension of 700 feet was completed in 1935. Old inner east breakwater 1,200 feet long was completed in 1909, and westerly 600 feet were removed in 1913 and 350 feet in 1935. The 18- and 16-foot sections of river channel and turning basin were deepened in 1939. A 25-foot deep approach channel through east outer harbor to easterly docks and a turning basin were completed in 1960. Deepening of this area to 28 feet, as authorized by 1965 act, was initiated in July 1967 and completed in June 1968. Deepening upper 1,550 feet of river channel to 16 feet was completed in July 1960. Deepening 29-foot entrance channel, 28-foot channel through outer harbor, 27-foot approach channel to Penn Central Co's. slip, 27-foot channel in Ashtabula River to a point 2,000 feet upstream from its mouth, and 22-foot areas in east outer harbor, as authorized by the 1960 act, was initiated in May 1962 and completed in June 1963. Harbor structures require repairs. Portions of both east and west breakwaters, rubblemound construction, where slope stone has pulled away, core stone has washed away, and deck stones have dropped, require major repairs. East breakwater light foundation tilted due to displacement of rubblemound protection and needs repairs. Work remaining to complete project consists of removal of 250 feet of inner breakwater, as authorized by 1937 act which is to be restudied and deepening triangular-shaped area adjacent thereto as authorized by 1960 act which is also to be restudied.

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 feet 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 be deposited along the downcoast shoreline as long as the area remains under Federal ownership or use 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). 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.

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.

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 1971) for existing project is $22,980,000, of which $21,500,000 is Federal cost, including $1,230,000 for basic recreation facilities, and $1,480,000 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 statutes 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 cost 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 were furnished by State Reclamation Board May 18, 1971. Operations and results during fiscal year.

Provides for construction of a 163-foot high earthfill dam to create a reservoir with gross storage capacity of 90,000 acre-feet for flood control, irrigation, recreation and other purposes. In conjunction with the dam, the project plan provides for about 7 miles of downstream levee and channel improvements on Fresno River from Fresno River bypass to Chowchilla Canal to accommodate project design flow of 5,000 cubic feet per second. Operation and maintenance of dam and reservoir would be responsibility of Federal Government. Approved estimated (July 1971) cost for existing project is $26,380,000, of which $25,000,000 is Federal cost, including $1,480,000 for basic recreation facilities, and $1,380,000 non-Federal cost 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 $300,000 for construction of low levees and clearing downstream channels to provide some local flood protection in the project area. This work is inadequate during major floods. Existing project was adopted by 1962 Flood Control Act (S. Doc. 37, 87th Cong., 1st sess., contains latest published map). Local cooperation. California officially adopted project by chapter 1202 of statutes 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 function of project. These costs are estimated at 21.7 percent of the joint-use first cost and 15.9 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 contract was executed by the Bureau with the Merced Irrigation District August 5, 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; relocations include relocation of highway facilities and utilities.

Estimated cost of this work (July 1971) 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 essentially completed 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 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. 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 1971) 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. Federal contribution of $2,216,508 was made to the City and County of San Francisco and Turlock and Modesto Irrigation Districts. Lower San Joaquin River and tributaries-Engineering continued. Condition at end of fiscal year. Tuolumne River Basin: Cherry Valley Reservoir-first phase, completed in 1950; New Don Pedro Reservoir-second phase, construction began in August 1967. Total Federal contribution as of June 30, 1971, was $4,438,022. Lower San Joaquin River and tributaries: Construction began in July 1956 and project is about 94 percent complete. Remaining work is recently reactivated improvement on left bank levee in Tuolumne River to Merced River reach. State of California construction on non-Federal portion of project above mouth of Merced River, initiated in fiscal year 1960, is complete. 23. MARTIS CREEK LAKE, MARTIS CREEK, NEV. AND CALIF. Location. Reservoir to be on Martis Creek, a tributary of Truckee River, near Truckee, Calif.; intermittent channel improvements would be on Truckee River in Reno, Nev. (See Geological Survey quadrangles for areas.) 35 - 14 SACRAMENTO, CALIF., DISTRICT Existing project. Provides for construction of 113-foot high rolled-earthfill dam to create a reservoir with gross storage capacity of 20,000 acre-feet for flood control and future municipal and industrial water supply. In conjunction with the dam, the project provides for construction by local interests of intermittent channel improvements in Reno, Nev., necessary to provide a flood-carrying capacity of 14,000 cubic feet per second through the city. Approved cost estimate (July 1971) for existing project is $8,450,000, of which $8,350,000 is Federal cost including $195,000 for basic recreation facilities, and $100,000 is non-Federal cost for channel improvement in Reno, Nev. In addition, local interests have, over a period of years, expended about $200,000 for construction of flood control channels within city of Reno. This work is inadequate during major floods. Existing project was authorized by 1962 Flood Control Act (H. Doc. 435, 87th Cong., 2d sess., contains latest published map). Local cooperation. Local interests must provide a channel capacity of 14,000 cubic feet per second in Truckee River through Reno, Nev., including necessary modification and relocations of existing structures and facilities. Local interests must maintain completed channel as required to preserve channel capacity of 14,000 cubic feet per second; establish effective regulations to prevent any encroachment within channel in Reno, and insure that all bridges or other structures to be built or rebuilt across channel in Reno afford an adequate and unrestricted waterway; maintain channel of Truckee River between Reno and the California-Nevada State line clear of all floatable debris and other drift large enough to restrict bridge openings in Reno during floods; and adequately inform interests affected that project (reservoir and related channel improvements) does not provide protection against maximum floods. Formal assurances requested from the Carson-Truckee Water Conservancy District September 8, 1967, were furnished November 13, 1967. Operations and results during fiscalyear. New work: Land acquisition, $445,798, and engineering, $64,072, were continued. Main dam and appurtenances contract was continued, $1,851,694. Condition at end of fiscal year. Construction of project was initiated in August 1967 and is about 63 percent complete. 24. MERCED COUNTY STREAM GROUP, CALIF. Location. Reservoirs and channel improvements are on Bear, Burns, Mariposa, and Owens Creeks, in foothills of Sierra Nevada about 15 to 20 miles east of city of Merced, Calif. (See Geological Survey Haystack Mountain quadrangle for Burns and Indian Gulch quadrangle for Bear, Owens, and Mariposa areas.) Existing project. For description of completed improvements and authorizing act, see Annual Report for 1962. Improvements consist of reservoirs at Mariposa, Owens, Burns, and Bear Creeks and diversions from Black Rascal Creek to Bear Creek and from Owens Creek to Mariposa Creek. Total first cost for project was $3,899,259, of which $2,751,259 was Federal and $1,148,000 non-Federal for lands including relocations and channel improvement. Local cooperation. Fully complied with. Operations and results during fiscal year. Maintenance: Ordinary maintenance and operation of the four completed reservoirs continued at costs as follows: Mariposa $8,159; Owens $6,377; Bear $14,683; and Burns $8,048. Structures were maintained in a serviceable condition. Runoff from drainage areas above Merced County stream group reservoirs was below normal for the year. (See table 35-H for maximum inflow storage and outflow for projects.) Outflows were less than channel capacity rates in the project streams. Condition at end of fiscal year. Construction was initiated March 1948, with construction of Mariposa project, which was completed in November 1948. Construction of Owens project, initiated in March, was completed in October 1949; Burns project, initiated in July 1949 was completed in January 1950; and Bear project, initiated in April, was completed in December 1954. Black Rascal and Owens Creek diversion channels and stream-gaging stations were completed in April 1956. Local interests completed channel enlargement and restoration of channel capacities of Miles, Burns, Owens, and Mariposa Creeks in 1956 at their expense. Improvement of Bear Creek and Black Rascal Slough, below their confluence, was deferred pending possible improvements downstream, outside limits of project. 25. MERCED COUNTY STREAMS, CALIF. Location. In vicinity of city of Merced, Calif., on streams draining from Mariposa County foothills of the Sierra Nevada into Merced County. Streams lie easterly of and drain into the San Joaquin River between Chowchilla River on the south and Merced River on the north. Drainage area represents about 1,000 square miles; nearly 700 square miles of foothills and mountains in Mariposa County and about 300 square miles of flood plain in Merced County. (See Geological Survey quadrangles for area.) Existing project. Project is a modification of Merced County Stream Group, Calif., Improvement No. 24, authorized by 1944 Flood Control Act (H. Doc. 473, 78th Cong., 2d sess.) and completed fiscal year 1957. Existing project provides for construction of three new reservoirs-Castle, Haystack Mountain, and Marguerite on Canal, Black Rascal, and Deadman-Dutchman Creeks, respectively, and enlargement of four existing reservoirs-Burns, Bear, Owens, and Mariposa, providing a total capacity of 126,700 acre-feet for multipurpose storage; and about 52 miles of levee 35 - 15 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 and channel improvements in lower reaches of Bear, Black Rascal, Mariposa, and Deadman Creeks, thereby tying the existing project channels into the Eastside Bypass of San Joaquin River flood control system. Haystack Mountain, Bear, and Owens projects would provide flood control only; Castle and Burns projects, flood control and recreation; Marguerite project, flood control and irrigation; and Mariposa project, all three purposes. Approved cost estimate (July 1971) for existing project is $41,040,000, of which $38,300,000 is Federal, including $2,380,000 for basic recreation facilities, and $2,740,000 is non-Federal. For future non-Federal reimbursement, see Local cooperation paragraph. Existing project was adopted by 1970 Flood Control Act (Document not yet printed.) Local cooperation. Based on cost allocation studies contained in Merced County Streams Review Report, about 26.5 percent of cost of Marguerite project and 17.7 percent of the cost of the Mariposa project (estimated at $3,110,000) is allocated to irrigation. Amount would be added to Central Valley Project and repaid through the sale of water from CVP by the U. S. Bureau of Reclamation. In addition, one-half the separable cost of recreation and fish and wildlife enhancement (estimated at $5,330,000) will be repaid over a period of years by local interests. If the Secretary of the Interior is unable to make necessary repayment arrangements for irrigation services to be provided at either of two reservoirs, Mariposa or Marguerite, within three years after request by the Secretary of the Army, such reservoir, or reservoirs, may be constructed without irrigation function and reservoir capacity reduced accordingly. Regarding levees and channels, local interests must provide all lands, easements, and rights-of-way; hold and save the United States free from damages due to construction of works; maintain and operate works after completion; accomplish all relocations and alterations to existing improvements, including highway facilities, which may be required for construction of projects; plus prevent encroachment on channels and preserve, at 1968 capacities, the flood channels within project area which are not improved by proposed project. Merced County must provide guidance in preventing unwise future development of flood plain by use of appropriate flood plain management techniques, and must at least annually inform affected interests of degree of protection provided by project. Merced County Board of Supervisors by resolution November 1, 1966, and reaffirmed by letter August 18, 1967, indicated willingness to meet requirements of local cooperation. Operations and results during fiscalyear. None. Condition at end offiscalyear. Preconstruction planning has not been initiated. 26. MERCED RIVER, CALIF. Location.

North Fork Pit River drains an area of 211 square miles south of Goose Lake on the western slopes of the Warner Mountains. Runoff from the area converges on the restricted channel through the city of Alturas in Modoc County, Calif. Most of the North Fork basin is located in the Modoc National Forest. Existing project. Provides for limited enlargement and rectification of channel through city of Alturas and some enlargement of the North Fork downstream to its confluence with the South Fork. Estimated (July 1971) cost for project is $1,320,000, of which $1,000,000 is Federal cost (including $41,800 for preauthorization studies) and $320,000 is non-Federal cost. Existing project approved by Chief of Engineers August 22, 1967, under provisions of section 205, 1948 Flood Control Act, as amended. Local cooperation. Local interests must bear all project costs in excess of Federal limitation of $1,000,000; furnish all lands, easements, rights-of-way, and relocations necessary for the project (exclusive of railroad facilities); hold and save the United States free from damages; operate and maintain the completed works at their own expense in accordance with prescribed rules and regulations; and prevent future encroachment which might interfere with proper functioning of project for flood control. Formal assurances furnished by the Board of Modoc County Supervisors were accepted by the District Engineer 1 December 1967. Rights-of-way requested from Modoc County on March 7, 1968, were received on July 30, 1969. Operations and results during fiscalyear. Engineering was continued. Channel improvement and levee construction were continued by contract, $309,520. Gabions supplied by contract at cost of $54,112. Condition at end of fiscal year. Construction was initiated in August 1969 and is about 64 percent complete. 30. PINE FLAT LAKE AND KINGS RIVER, CALIF. Location. Reservoir is on Kings River, about 25 miles east of Fresno, Calif., and channel improvements are on Kings River downstream from Lemoore weir, about 25 miles south of Fresno. (See Geological Survey quadrangles of area.) Existing project. Improvement is a unit in comprehensive plan for flood control and other related purposes for Sacramento-San Joaquin Basins. Project consists of a 429-foot high concrete gravity dam, including a gated overflow section with a maximum discharge capacity of 391,000 cubic feet per second, creating a reservoir with gross storage capacity of 1 million acre-feet, for flood control, irrigation, and related purposes. Outlet provisions for future power development are included in dam, but Federal construction of power-generating facilities is not 35 - 17 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 authorized. Improvement also includes a limited amount of channel improvement on Kings River and its distributaries on valley floor about 25 miles south of Fresno. Channel improvement work will enlarge channel capacities and regulate flows in lower branches of the Kings River. There are nine public-use and recreation areas: One maintained by the Corps, four by the Forest Service, three jointly by the Corps and concession, and one by Fresno County. Also, five boat access-only areas are maintained by the Corps on the south side of reservoir. Approved cost estimate (July 1971) is $41,235,000, of which $40,685,000 is Federal (including $13,700 for basic recreation facilities) and $550,000 non-Federal for rights-of-way for downstream channel improvements. For future non-Federal reimbursement, see Local cooperation paragraph. Estimated Federal cost of recreation facilities for Pine Flat Lake, to be funded from Code 710 appropriations is $947,100 (July 1971) exclusive of recreation facilities previously provided at a cost of $13,700. In addition, Federal cost of recreation facilities for Pine Flat Lake, 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 $10,846,865 for irrigation services through December 31, 1970. 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-of-way 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 the Pine Flat reservoir. Under interim 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 the Pine Flat reservoir May 15, 1954, through March 31, 1955. Current Contract No. DA-04-167-eng-1328 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, 1971, amounts to $2,383,025; 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. Channel restoration in Centerville Bottoms, Kings River, completed by contract, $94,846. 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 $75,287 and major maintenance costs as follows: Dam and reservoir $70,521; service facilities $38,864 and recreation facilities $81,950. Structures were maintained in serviceable condition. Runoff of Kings River above Pine Flat Dam was below normal for the year. Maximum storage of 829,300 acre-feet on July 1, 1970. Maximum daily inflow to the reservoir was 5,577 cubic feet per second on May 16, 1971. Maximum outflow of 6,525 cubic feet per second occurred on June 30, 1971. Release of water for irrigation and spreading totaled 1,416,500 acre-feet. Condition at end of fiscal year. Construction began in April 1947 and project is about 99 percent complete. Main dam was initiated inJanuary 1950, completed in June 1954, and has been operating since February 1954 to provide flood protection for which it was designed. Total of 21.9 miles of channel improvement have been transferred to the Kings River Conservation District for maintenance. Recreation facilities for various recreation areas under Code 710 appropriation in- 35 - 18 SACRAMENTO, CALIF., DISTRICT itiated in fiscal year 1960 are 42 percent complete. Work remaining consists of completion of minor channel improvements and recreation facilities in connection with overall development of reservoir area. 31. SACRAMENTO RIVER AND TRIBUTARIES, CALIF., FROM COLLINSVILLE TO SHASTA DAM 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. Works covered by this improvement are on Sacramento River and tributaries from Collinsville to Shasta Dam, about mile 312. Drainage area above Rio Vista is 26,500 square miles. (See Geological Survey quadrangles of area for Sacramento River and Upper Butte Basin; Flournoy and Fruto quadrangles for Black Butte Lake; and Tuscan Buttes, Tehama, Redding, and Hooker quadrangles for Table Mountain Lake.) Existing project. Improvement of Sacramento River and tributaries, from Collinsville to Shasta Dam was authorized as a unit of a comprehensive plan for flood control and other related purposes in Sacramento River Basin. (a) Sacramento River and major and minor tributaries, for flood control purposes: Enlargement of existing levees on Sacramento River between vicinity of Moulton weir and Ord Bend; construction of new levees from present levee terminus to vicinity of Chico Landing; construction of a weir near Chico Landing, extension of Moulton weir, and construction of a bypass through Upper Butte Basin; construction of new levees in Lower Butte Basin; enlargement of existing levees in Sutter, Tisdale, Sacramento, and Yolo Bypasses; and levee construction and/or channel enlargement on following minor tributaries of Sacramento River: Antelope Creek; Chico and Mud Creeks and Sandy Gulch; Butte and Little Chico Creeks; Cherokee Canal; Elder Creek; Deer Creek (Tehama County); Thomes Creek; and Willow Creek. Improvement provides for about 155 miles of channel improvement and about 294 miles of levees with an average height of 12 feet and a freeboard of 3 feet. Improvement also provides for revetment as required for protection of bypass levee slopes against erosion. Total first cost for project is $18 million (July 1971), of which $11,900,000 is Federal, and $6,100,000 non-Federal for lands and damages, including relocations. (See table 35-I on project units classified and excluded from cost estimate.) (b) Construction of about 45,000 feet of bank protection and minor channel improvements as required on Sacramento River between Chico Landing and Red Bluff, for flood control purposes. Improvement also contemplates flood plain zoning between Chico Landing and Keswick Dam to assure maintenance of present project floodway areas. Estimated first cost (July 1971) for project work in Tehama County, is $1,235,000, of which $1,105,000 is Federal cost and $130,000 non- Federal for lands and damages including relocations. Construction in Butte and Glenn Counties is considered inactive and excluded from foregoing cost estimate. (c) Sacramento River, Calif., bank protection-Addition of about 430,000 lineal feet of bank erosion control works and setback levees at critical locations existing at time of report or expected to develop in 10 years, within limits of authorized or existing levees included in Sacramento River flood control project, as initial phase of a long-range program to protect integrity of levee system, for flood control purposes. Total estimated (July 1971) first cost for this initial phase of project is $41,700,000, of which $27,800,000 is Federal (including $400,000 for recreation facilities) and $13,900,000 non-Federal comprising $11,800,000 for lands and damages including relocations and $2,100,000 required cash contribution toward first cost. Construction in (a), (b), and (c) above supplements program of levee improvements which is being accomplished pursuant to 1917 Flood Control Act, as amended by subsequent acts, including 1941 Flood Control Act, and which are reported by California Debris Commission under Sacramento River, Calif., flood control. (d) Authorization also provided for Black Butte Lake by construction of an earthfill dam, with a maximum height of 156 feet, to create a reservoir with gross storage capacity of 160,000 acre-feet for flood control, irrigation, and related conservation purposes. Improvement is in Tehama and Glenn Counties about 9 miles westerly of Orland, Calif., on Stony Creek, a tributary entering Sacramento River at mile 190. Estimated (July 1971) Federal first cost for project is $14,515,000, including $468,000 for basic recreation facilities. For future non- Federal reimbursement, see Local cooperation paragraph. Approved estimated Federal cost for additional recreation facilities to be funded from Code 710 appropriations is $1,032,000. (e) Authorization also provided for construction of Table Mountain (Iron Canyon) project, an earthfill dam, with a maximum height of 210 feet, to create a reservoir with gross storage capacity of 503,000 acre-feet, for flood control, water conservation, and power generation. Reservoir would be on Sacramento River at about mile 250, about 3 miles north of Red Bluff, in Tehama and Shasta Counties, Calif. This project unit was reclassified and is in a deferred status. Estimated Federal cost of this unit, including power facility, (July 1954) is $77,200,000. Local interests would be required to pay the portion of first cost and annual operation and maintenance cost allocated to conservation functions of the project. These costs have not been determined.

South Fork and Millicoma Rivers rise in Coast Range in southern Oregon, flow generally westerly and join to make Coos River, 5.3 miles above mouth of Coos River in Coos Bay. (See Geological Survey, Coos Bay Quadrangle.) Existing project. Originally authorized project; a channel depth of 3 feet, generally, from mouth of coos river and 1 foot near head of navigation. Project as modified; two channels 5 feet deep and 50 feet wide from mouth of Coos River to Allegany on Millicoma River, mile 13.8 and to Dellwood on South Fork, mile 14, and thence a channel 3 feet deep and 50 feet wide to mile 14.7 on South Fork, including stabilization works on Coos River. Mean lower low water is plane of reference. Tidal range between higher high water and plane of reference and extreme tidal ranges under ordinary conditions at mouth of Coos River are 7.3 and 11 feet, respectively, and there is a tidal range of about 1 foot at head of navigation in both forks. Freshet stages usually reach a height of from 10 to 15 feet at Allegany, head of navigation on Millicoma River. Existing project was authorized by River and Harbor Acts of June 3, 1896 (H. Doc. 237, 53d Cong., 3d sess.) and modified June 30, 1948 (S. Doc. 124, 80th Cong., 2d sess.). Latest published maps are in these documents. Local cooperation. Fully complied with. Terminal facilities. Several small privately owned docks and landing places on the river are used by towboats and pleasure craft. There are no publicly owned docks. Present facilities are considered adequate for existing commerce. Project modification provides for construction of terminal facilities open to all on equal terms. Operations and results during fiscal year. Maintenance: Snagging and clearing activities was accomplished by hired labor and rental equipment. A total of 24,525 cubic yards of material was dredged. Condition at end of fiscal year. Originally authorized project providing for a channel from mouth of Coos River to head of navigation in both forks, to provide a depth of 3 feet generally and 1 foot near head of navigation, was completed in 1899. In March 1966 construction of project as modified by 1948 River and Harbor Act has been accomplished except for removal of rock encountered, which was accomplished in August 1966. Since scour that had been anticipated in Coos River has not developed, it has been recommended that construction of stabilization work be held in abeyance until need has been established. 10.

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 have been disbanded. The Flood Control Plan has been completed, except for portions affecting Libby project in Montana, pending possible modification of the International Joint Commission Orders for Kootenai Lake. Costs during fiscal year were $69,988. 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 report. One of those reports was started in fiscal year 1970 and two were undertaken in fiscal year 1971. A narrative,including a description of the flood situation along each stream studied, was also prepared for publication in the reports. Of the three reports the following one, "Albany, Oreg., Flood Plain Information Report- Willamette River, Calapooia River, and Oak Creek", is near completion, while the other two are identified in Table 37-R. Costs for flood plain information studies during the fiscal year were $163,804. Total costs for collection and study of basic data were $233,792. 67. RESEARCH AND DEVELOPMENT Water quality investigation. Program of observing water temperatures and meteorological data at specific Willamette storage projects were continued. The Fish Commission of Oregon is still active in monitoring specific projects where they have a definite fishery interest. Stored water in Willamette reservoirs was released in substantial quantities during the summer of 1970 to increase streamflow for navigation, water quality, and fish life. There is a previous dissolved oxygen deficiency in the Portland Harbor during late August and early September which benefits from this 37 - 29 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 program to alleviate low flows during the summer and early fall. The Portland District continued its financial assistance to study the temperature of lower Columbia River in connection with feasibility studies for a nuclear power plant to be located on lower river. The turbidity problems still exists at Hills Creek and a contract has been negotiated with Oregon State University to monitor and investigate factors that might be contributing to that problem. Nitrogen supersaturation has become a serious fishery problem and much effort was devoted to studying the contributing factors and how future project operation and design might be modified to alleviate that situation. Hydrologic studies Reservoir temperatures, solar radiation, dissolved oxygen, suspended sediment, and nitrogen supersaturation were analyzed in greater depth and procedures developed wherein, the electronic computer could be used to analyze and forecast the outcome that existing projects would have on those environmental factors. A consulting firm was retained to assist in the study program. The initial phase of installing an automated hydrologic reporting network in the Willamette Basin is in the design stage. This program will be in at least three stages of development with the less sophicated portion of the network being undertaken initially. Maximization of proposed storage projects is receiving greater attention and new thinking is being incorporated into the studies. Greater use is being made of the electronic computer in making hydrologic and water resource studies. Flood plain investigations for flood plain zoning and flood plain insurance programs are being pressed by local interests. Environment and ecology effects are being incorporated into all hydrologic studies. Civil Works Investigations. The erosion test program that was being performed in the Detroit Test Conduit (ES 825) has been combined with ES 628, Epoxy Resins and Other Adhesives for Concrete. No work has been done on ES 825 during the past year. 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 of standard engineering systems used on the IBM 360 Model 50 installed at the North Pacific Division is continuing. Installation of a graphic display terminal and remote teletype terminals in the Engineering Division will permit faster development of engineering applications using a real time computer system. Total research and development costs were $9,564. 37 - 30 PORTLAND, OREG., DISTRICT TABLE 37-A See Section in Text Project 1. Alsea Bay and River, Oreg. 2. Chetco River, Oreg. 3.

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 Henrys 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 2,000 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 * 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. 39 - 1 1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 21,700 cubic feet per second by lowering crest elevation from 6118.5 to 6112 and increasing spillway width from 52 feet to 94 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 10 feet and Idaho State Highway No. 34 would be raised in grade for approximately one-half 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 1971) is $3,100,000. Local cooperation. None required. Operations and results during fiscal year. Preconstruction planning continued throughout fiscal year. Condition at end of fiscal year. Hydrology design memorandum has been approved. The general design memorandum has been conditionally approved subject to comments of the Office of Management and Budget on postauthorization changes. 3. CATHERINE CREEK LAKE, OREG. Location. On Catherine Creek about 8 miles above Union, Oreg., 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 rockfill zones 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 the dam. Spillway will have three 15- by 18.5-foot tainter gates having a capacity of 11,740 cubic feet per second. Lake will contain 61,000 acrefeet of water with 58,000 acre-feet of usable space at elevation 3440.

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 oceangoing 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 unusable. Expansion of the existing city dry cargo wharf is underway. Operations and results during the fiscal year. Regular funds, maintenance: Maintenance dredging contract was awarded June 1971 to restore project depth of 37 feet, adjacent to the POL dock. Dredging was accomplished August and September 1970 by removal of 42,788 cubic yards of material. Project sedimentation studies continued. The annual maintenance dredging contract was awarded June 30, 1971. Condition at end of fiscal year. Maintenance dredging was accomplished jointly with local interests and United States Army to provide a depth of 35 feet adjacent alongside the newly constructed city dock and 32 feet at a distance of 50 feet from the ocean dock in July 1961. The first phase of new work in the authorized project consisting of dredging the port area to a depth of 35 feet in October 1966 and was completed June 1967. (For further details see Annual Report for 1967.) * All cost and financial statements for projects are listed at the end of this chapter.

BETHEL SMALL BOAT HARBOR, ALASKA Location. The village of Bethel is 65 miles upriver on the north bank of the Kuskokwim River which flows through southwestern Alaska. Existing project. Project includes provisions 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. Estimated cost of the project is $835,000. (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 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 $1,000,000. Operations and results during fiscal year. Regular funds, new works: Plans and specifications were initiated January 1970. Authorization for procurement of the dredge with project funds has been granted Alaska District. Award was made April 20, 1971 for purchase of hydraulic dredge, which is scheduled to be delivered to the project in September 1971. Condition at end of fiscal year. Construction has not been initiated. 3. 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, and 300 miles southwest of Anchorage. (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 width of 40 feet in Scandinavian Creek, and sheet sill across the basin outlet with a top elevation of 7 feet above mean lower low water.

Tables are referenced in text and appear at the end of this chapter. The Board of Engineers for Rivers and Harbors is a continuing body created by section 3, 1902 River and Harbor Act. The Board comprises 7 senior engineer officers: The Chairman, five members who are Division Engineers (rotative basis) from continental U. S. Army Engineer Division, and the Resident Member, who 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 or 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 resource 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. On June 30, 1971 the Board was composed of the following members: Maj. Gen. Willard Roper, 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; Brig. Gen. Roy S. Kelley, Division Engineer, U. S. Army Engineer Division, North Pacific; Brig. Gen. Harold R. Parfitt, Division Engineer, U. S. Army Engineer Division, Southwestern; and Col. Alvin D. Wilder, Resident Members. In addition to the foregoing, the following officer was also assigned for part of the year as Chairman of the Board: Maj. Gen. C. H. Dunn, Deputy Chief of Engineers. A summary of investigations authorized by the Congress from establishment of the Board in 1902 to the end of the fiscal year 1971, 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, 1971, the Board took final action on 8,060 reports, recommending favorably on 3,576 and unfavorably on 4,484. During fiscal year 1971, the Board held three meeting of 1 to 2 days' duration in Washington. The Board considered 54 reports, acted favorably on 19, unfavorably on 23, deferred action on 5, and returned 1; reporting offices withdraw 6. The Board recommended construction of projects totaling $753,367,000 of which $455,889,500 was the estimated U. S. cost and $297,477,500 the cost to local interests for work and cash contributions. Of the 23 unfavorable reports acted on by the Board, 1 involved construction costs estimated at $3,794,000 consisting of $3,735,000 Federal, and $59,000 non- Federal. The remaining 22 reports contained no cost 41 -1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 estimates as they dealt with improvements that were reviews (preliminary reviews with special purposes in obviously unfavorable or no longer necessary.

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 in 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 115 miles below New Orleans. It is improved for barge navigation for 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 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 5 miles. (See map of alluvial valley of Mississippi River, scale 1:500,000.) Observations made by Mississippi River Commission to June 30, 1971, 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 660,000 and 11,000 cubic feet per second in Atchafalaya River. As the 1927 floodflow was not confined between levees, maximum discharges recorded do not include entire flow of the 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 60 feet at Cairo, 55 feet at Memphis, 58 feet at Red River Landing, and 23 feet at New Orleans (Carrollton). The 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. The Mississippi River and tributaries project in the alluvial valley between Head of Passes, La., and Cape Girardeau, Mo., provides protection 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 the main stem between Cape Girardeau and Rock Island. When completed, 23,621 square miles will be protected from the Mississippi River project flood. The 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 lakes 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 the existing project began in 1928 and has continued throughout ensuing years. Based on the estimated cost of $3,035,927,000 (July 1, 1971 price levels) and actual expenditures through June 30, 1971 of $1,675,957,800, the entire project is about 55 percent complete.

(See also Tables 42-R, 42-T, and 42- U for additional financial statements.) Operations and results during fiscal year. Commission activities: The 282d session was held, October 5-9, 1970, on board the U. S. MV Mississippi en route on the Mississippi River from Cairo, Ill., to Old River, La., on Old River to the Atchafalaya River, and on the Atchafalaya River to Morgan City, La. The 283d session was held, December 11, 1970, at the Roosevelt Hotel, New Orleans, La., for the purpose of reviewing progress on the West Texas and Eastern New Mexico Water Import Study. The 284th session was held, May 10-15, 1971, on board the U. S. MV Mississippi en route on the Mississippi River from Cairo, Ill., to the Head of Passes, La. On the 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 282d session, revetment sinking operations at Smith Point were inspected. During the 284th session an onthe- ground inspection was made of casting operations at the St. Francisville, La., Casting Field. 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. The following reports were forwarded to OCE during the fiscal year: Separate favorable report, "Mississippi River East Bank, Warren to Wilkinson Counties, Mississippi-Vicksburg-Yazoo Area," dated November 18, 1970, recommended construction of flood control improvements, under the Levees feature of the MR&T Project, for the Vicksburg-Yazoo Area. These improvements are justified to alleviate flood damage to approximately 16,000 acres of agricultural, residential, and commercial lands, and to provide additional floodfree lands for future development. Favorable report, "Mississippi River, East Bank, Warren to Wilkinson Counties, Mississippi," date May 12, 1971, recommended construction of flood control improvements for the Natchez Area. The proposed improvements include 12.4 miles of levee to protect against Mississippi River Project Design Flood, a 300-cubic-foot-per-second pumping plant, 12 miles of channel improvements, three 8-foot by 8-foot floodgates with concrete box culverts, and a conservation weir. Two Fish and Wildlife Mitigation reports as follows: "West Tennessee Tributaries Feature-Mississippi River and Tributaries Project (Obion and Forked Deer Rivers)," dated March 24, 1971. The mitigation plan consists of minor modifications to the existing project, and acquisition and development of approximately 14,000 acres of land for fish and wildlife purposes. "Mississippi River and Tributaries-Cache River Basin Project, Ark.-Cache River and Bayou De- View," dated May 7, 1971. The proposed mitigation plan consists of acquisition and limited development of 30,000 acres of woodland in the flood plains of lower Cache River and Bayou DeView, for fish and wildlife purposes. 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 the subject of flood control and navigation. Preparation and publication of quadrangle maps (scale 1:62,500) continued. The 1970 (38th) 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 5,669 flight-line miles of aerial photography (various scales) were flown along Mississippi River and tributaries in the New Orleans, Vicksburg, and Memphis Districts. Work accomplished in the districts: New Orleans District-Series conversions of the Bonnet Carre, Chef Menteur, Covington, Hahnville, Ponchatoula, r Rigolets, St. Bernard, and Yscloskey, La., quadrangles were printed. Work on the Opelousas, Palmetto, Fordoche, and Maringouin, La., quadrangles is in progress. 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 Pace and Marks, Miss., quadrangles were printed. Work on the Stuttgart and Dumas, Ark., and Greenville and Readland, Miss.-Ark., quadrangles is in progress. Memphis District-Three series conversions, Greenville and Poplar Bluff, Mo., and DeWitt, Ark., quadrangles were printed. Teague and Whiteville, 42 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Tenn., and Augusta and De Valls Bluff, Ark., quadrangles are ready for printing. Alamo, Humboldt, and Middleton, Tenn., and Clarendon and Gregory, Ark., quadrangles are ready for color proofs. Work on the Charleston, Mo., and Greenfield and Mason, Tenn., quadrangles is 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 48.24 feet at Cairo gage and maximum discharge of 1,166,000 cubic feet per second occurred on March 5, 1971 at Hickman, Ky., due to moderate to heavy rains that fell, during the period February 11-March 1, over the lower Missouri River and Ohio River Valley. Vicksburg District -Stages on the Mississippi River were about normal during the year. Maximum stages occurred in March with crest stages 10.8 feet below flood stage at Arkansas City, 4.0 feet below flood stage at Vicksburg, and 5.7 feet below flood stage at Natchez. Stages on the Ouachita River were low during the entire year. The crest stage at Arkadelphia occurred January 6, 1971, and was 5.7 feet below flood stage. The crest at Camden occurred March 15, 1971, and was 8.9 feet below flood stage. Flood control works reduced crest stages about 11 feet at Arkadelphia. Flood control works reduced the crest stage at Camden for the October 1970 storm from about 29 feet, without flood control works, to the observed stage of 13.8 feet, a reduction of about 15 feet. Stages on the Coldwater- Tallahatchie-Yazoo Rivers were moderately low throughout the year. Principal rises were in late January and late February. The crest stage at Swan Lake occurred on February 28 and was 0.3 foot below flood stage. Crest stage at Greenwood occurred February 28 and was 5.2 feet below flood stage. The river at Yazoo City crested March 3 and was 0.5 foot below flood stage. Operation of flood control works effected reductions averaging about 6 feet on the Coldwater and Tallahatchie Rivers, about 3 feet at Greenwood, and 5 feet at Yazoo City. Major rises occurred on the Big Black River in March and again in May. The river crested about 10 feet above flood stage each rise. 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 $62,336 on one navigation study, $217,645 on seven flood control studies, and $40,001 on collection and study of basic data. Vicksburg District expended $189,388 on six flood control studies, and $69,767 on collection and study of basic data. New Orleans District expended $140,686 on three flood control studies and $15,127 on one navigation study. Surveys were made and gages operated and maintained. In addition, $597,082 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, 6.3 miles in New Orleans District, and 4.6 miles in Memphis District; construction of levee berms, 6.2 miles in Vicksburg District. 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 1,599 miles of levee now authorized for the Mississippi River below Cape Girardeau, of which 1,568 are in place with 1,365 built to approved grade and section. The Main Stem Levee System consisting of 2,194 miles, of which 1,684 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 314.7 essentially completed (181.7 to grade and section and 133.0 to grade only). Graveled or hard-surfaced roads have been constructed on 969 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 levee-slope 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. 42 - 4 MISSISSIPPI RIVER COMMISSION 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 16.8 miles of new bank revetment and 6.1 miles of reinforcement of existing revetment along the Mississippi River was completed by Government plant and hired labor, and construction of 11.4 miles of new dikes was completed by contract. Reinforcement of about 0.8 mile of existing foreshore protection at two locations 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 50,865,000 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- 0, 42-P, and 42-Q.) Other work performed in interest of navigation, supplementing maintenance dredging on Mississippi 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 of fiscal year. 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 625 miles of operative bank revetment and 127 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.

Army Coastal Engineering Research Center 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 Engineering 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 1971 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 Richard H. Free, U. S. Army, Division Engineer South Atlantic Division; Brigadier General William M. Glasgow, Jr., U. S. Army, Division Engineer, South Pacific Division; Brigadier General Ernest Graves, Division Engineer, North Central Division; Dean Morrough P. O'Brien, Dean Emeritus, College of Engineering, University of California at Berkeley; Dr. Arthur T. Ippen, Institute Professor, Massachusetts Institute of Technology; and Dr. Robert G. Dean, Chairman, 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 research 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 Engineeers and, as directed, to other Federal agencies. 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 28 reports for technical adequacy; of which 5 concerned navigation projects; 20 (including 9 regional inventory reports and the draft report of the Chief of Engineers for the National Shoreline Study) concerned beach erosion control projects, and 3 concerned combined beach erosion control-navigation projects. In keeping with the responsibility for publishing information and data concerning coastal phenomena, a number of technical reports by staff members were published by CERC or in other technical journals during the year and others are currently in press. Four Technical Memorandums were issued by Coastal Engineering Research Center and 3 are in preparation to go to press. One technical manuscript was published in the "Miscellaneous Papers" series. The Center's major compendiurt on shore protection (Technical Report No. 4 "Shore Protection Planning and Design") went out of print and is being reprinted in FY 72. A revised and updated edition of this report is in preparation. The staff worked on several major research or engineeering projects for various agencies and prepared reports thereon. A number of lesser studies were also 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 another on inlet characteristics and hydraulics was given for Corps personnel; lectures were given by staff members to universities and to technical and nontechnical groups. Members of the staff participated in a number of committees of various technical societies. A 43 - 1 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 staff member was appointed to the Permanent International Commission of the Permanent International Association of Navigation Congresses. Research to supplement staff activities was carried out at universities and with institutions and commercial concerns under approximately 40 contracts; funds were supplied other Corps offices for data collection; and 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 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 source of sand for use as beach fill; the durability of various pile coatings in the surf zone; the relation of longshore transport to incident waves; the techniques for measuring longshore transport 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 ecology effects of offshore dredging; the correlation of wave climate and beach deformation; the revision and updating of Technical Report No. 4, Shore Protection Planning and Design; the use of the middle ground shoal area as a deposition trap in sand bypassing; the evaluation of completed coastal works; the use of remote sensors for coastal pruposes; and others. 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 1971 appropriated and allotted funds in these three categories amounted to $3,250,000, $250,000, and $80,000 respectively. Reimbursable work done for other provided another $142,000. 43 - 2 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.

Dam is 155 feet high, 620 feet long, and reservoir has debris storage capacity of 26 million cubic yards. Harry L. Englebright project 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 Dam are maintained by the Corps. Recreation areas at North Fork Dam 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 1971) that improvements to recreation areas will cost $1,075,000 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 River, 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. Improvements made to facilities at North Fork Dam 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, 1971, amounts to $504,100; these funds are paid to California Debris Commission and deposited for return to the Treasury. License No. 2246, effective April 9, 1970 (date New Narrows powerplant put in operation) was issued by Federal Power Commission to Yuba County Water Agency for hydroelectric power development of Yuba River by the company upstream from Englebright Dam. Under provisions of Contract No. DA-04-167- CIVENG-66-95 with Yuba County Water Agency, payment is to be made to the Federal Government of $100,000 per year for no more than 50 years. First payment (partial) of $73,151 was made April 1, 1971; these funds are paid to Sacramento District and deposited for return to the Treasury. Operations and results during fiscal year. Maintenance and operation activities continued at North Fork Dam at a cost of $21,227; and at Harry L. Englebright Dam at a cost of $73,553, including recreation facilities ($29,234). Condition at end of fiscal year. Construction of dams was initiated in 1937; North Fork project was completed and in use at end of fiscal year 1939; and Harry L. Englebright project 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, CALIF. 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 below 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, 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 44 - 2 CALIFORNIA DEBRIS COMMISSION 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 $48,411. 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.) Estimated (July 1971) 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., Ist 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 Cong., 1st sess.), and 1941 Flood Control Act (H. Doc. 205, 77th Cong., Ist 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. 44 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Operations and results during fiscal year. Regular funds: Engineering continued. 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, 1971.)

ARMY ENGINEER WATERWAYS EXPERIMENT STATION Organization and Functions. Waterways Experiment Station is a Class II activity of the Chief of Engineers operating under the staff supervision of the Director of Civil Works in accordance with General Orders No. 9, 1949. It was originally established as an hydraulic laboratory, 18 June 1929, under the President, Mississippi River Commission, by direction of the Chief of Engineers. 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, environmental ground mobility, flexible pavements, soils other than those phases involving seasonal frost and permafrost, concrete, nuclear and conventional weapons effects on structures, terrain and waterways, nuclear and chemical explosives excavation and cratering. 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 investigations 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; excavation cratering; 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. Performs sampling and testing of cement and pozzolan materials. Subject to approval by the Chief of Engineers, studies can also be undertaken for other agencies. The Waterways Experiment Station also operates Department of Defense Information Analysis Centers, particularly in, but not necessarily limited to, fields covered by Hydraulics, Soils Mechanics, and Concrete Technology and Pavements. 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 duplication of effort throughout the Corps in the conduct of experimental studies. Operates the engineering computer program library and provides automatic data processing, audiovisual training aids. During Fiscal Year 1971, 192 reports of individual studies conducted at the Waterways Experiment Station, 7 translations, 19 contract reports, and 24 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 2,594 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 1971 was $22,291,700 of which $20,123,820 was charged to establishments served for research investigations and related services, and $2,167,880 for permanent improvements and equipment. Of the reimbursable work, $7,653,420 was charged to civil funds, $12,149,489 to military funds, and $320,911 to nongovernmental agencies. Work includes $1,609,764 performed by contract. Total cost incurred for operation of the Waterways Experiment Station to June 30, 1971 was $286,204,820, of which $268,367,319 represents reimbursable cost and $17,837,501 the unamortized cost of permanent improvements and equipment. 45 - 1 PERMANENT INTERNATIONAL ASSOCIATION OF NAVIGATION CONGRESSES The United States by act of June 28, 1902, appropriated $3,000 annually 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, $2375 is paid by the American Section to the International Association 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 the 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 1971, National Commissioners were: MG F. P. Koisch, USA, ex-officio Chairman; Col. A. D. Wilder, CE, USA, ex-officio 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. Messrs. Ackerman, McCann, and Schad's term expired 31 December 1970 and they were succeeded by Mr. Minard I. Foster, RAdm Roderick Y. Edwards and Mr. Thorndike Saville on 1 January 1971. The annual meeting of the Permanent International Commission was held in Madrid, Spain on 25 May 1971, and was attended by the 10 National Commissioners. Membership of the American Section on June 30, 1971 totaled 705, consisting of 638 individuals and 67 corporate members. A total of 26 new individual members, 6 new corporate members, and 3 life members were added during the fiscal year, and 40 individual members and 2 corporate members deleted either through resignation, death, or non- payment of dues. Federal funds from annual appropriations were estimated as follows: annual U. S. contribution to association, $2,375; expenses of representatives to meetings, $7,350; and publications, $112 for a total of $9,837. 46 - 1 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: 14 plans approved by Chief of Engineers and Secretary of the Army in accordance with sec. 4 (e) of the Federal Water Power Act; 59 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. 47 - 1 MISCELLANEOUS CIVIL WORKS* IMPROVEMENTS TABLE OF CONTENTS 1.

INTERNATIONAL BOUNDARY WATER 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 jurisidiction 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 Bo'--' -all 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 have Corps of Engineers membership follows: end of this chapter. All other tables are referenced in text and also 48- 1 Page 48-11 48-12 48-12 48-13 48-13 48-13 48-14 48-15 48-15 48-15 48-16 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 and 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 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 feet (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 Commission issued an Order approving the reconstruction of the dam by the Canadians Cottons, Ltd., extending across the St. Croix River from Milltown, New Brunswick, Canada, to Milltown, Maine. The Order 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 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 the Order, be under the supervision of the Board of Control. On November 19, 1965, the Commission directed the Board, 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. The Board's report to the Commission, dated March 4, 1971, recommended on annual report due to reduced activity in the Basin. Members of the Board for fiscal year. Colonel F. P. Bane, Division Engineer, U. S. Army Engineer Division, New England, Waltham, Massachusetts, United States Member, and Mr. J. E. Peters, District Engineer, Water Survey of Canada, Department of Energy, Mines and Resources, Halifax, Nova Scotia, Canadian Member. Operations during fiscal year. Supervision was maintained and inspection was made by the Canadian and the United States members and their representatives to insure that the Order of Approval of the Commission were followed. On August 4, 1970, the Board of Control made its Annual Inspection of the St. Croix River Basin and met with officers of the New Brunswick Electric Power Commission at Milltown, New Brunswick, Canada, and the Georgia- Pacific Corporation in Woodland, Maine. The damage at the Milltown Dam attributable to the flood of February 1970 was repaired by the New Brunswick Electric Power Commission in the period from July 22 to August 8, 1970. During the year the Georgia-Pacific Corporation completed construction of its 31,000 kva, 0.9 pf thermal electric generating unit at Woodland, Maine. The unit went on line in November 1970. Routine inspections were made by field staff members to verify the accuracy of the flow and level data submitted by the reporting agencies. 2B. INTERNATIONAL SAINT JOHN RIVER ENGINEERING BOARD Constitution 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 interim 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 members, Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, Ottawa, Ontario, Chairman, Canadian Section and Mr. J. E. Bright, Regional Director, Atlantic Region, Department of Public Works, Halifax, Nova Scotia. The United States members were Mr. E. L. Hendricks, Chief Hydrologist, Water Resources Division, U. S. Geological Survey, Washington, D. C., Chairman, 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 Commission on activities of New Brunswick Power Commission, unchanged status of the Dickey-Lincoln School project with no progress on planning of the project or the related negotiations between the two countries on cooperative development of the Saint John River, 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 that an interim plan for water resource and water quality management was completed in October 1970, that collection of basic water supply and quality data and related hydrologic investigation were continued and that the North Atlantic Treaty OrganizatiorvCommittee on the Challenges of Modern Society has selected the Saint John River basin for a case study. 48 - 2 MISCELLANEOUS CIVIL WORKS 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, Conventry, 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 by the two Governments 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 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 Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, for Canada and Colonel J. W. Barnett, District Engineer, U. S. Army Engineer, District, New York for the United States. Operations during fiscal year. Supervision of the levels was maintained. The Water Resources Branch of the U. S. Geological Survey records daily readings of the elevation of Lake Memphremagog at Newport, Vermont. 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 comparable Geodetic Survey of Canada, 1923 adjustment. The upper limit of the recommended lake level was exceeded for the entire month of May 1971 (mean 0.39 feet above the recommended level) and several days in April and June. However, no complaints of flooding were received by the Corps of Engineers or the Vermont Department of Water Resources and it is therefore presumed that no serious damages occurred as a result. Maximum lake level occurred in May which was 0.88 feet above the recommended level. 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 Richlieu River at Fryers Island, Quebec. The Board submitted a report to the Commission dated May 4, 1939 soon after completion of the Fryers Island Dam. 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. Member of the Board for fiscal year. Mr. N. P. Persoage, Water Planning and Operations Branch, Department of Energy, Mines and Resources, for Canada, and Col. J. W. Barnett, District Engineer, U. S. Army Engineer District, New York, for the United States. Operations during fiscal year. Members of the Board inspected the Champlain-Richlieu Waterway on November 12-13, 1970 and provided a condition report to the Commission dated March 26, 1971. Construction work is in progress to widen the upper portion of the Chambly Canal in St. Johns, Quebec, by building a new dike further out in the river. The canal is also being widened to form a passing area basin in the vicinity of the auto-route highway crossing downstream of the Fryers Island dam. Inspection of the Fryers Island dam revealed that it was properly maintained. All gates are kept in their fully opened position. Test operation of the gates was carried out in the summer of 1970. Downstream of Fryers Island dam, local interests have constructed a gravel dam to improve conditions at their water supply intake. This structure is not expected to affect the levels of Lake Champlain. Because of the steadily deteriorating condition of the Chambly Canal, the Canals Division of the Canadian Ministry of Transport has considered a plan of improvement to use the main channel of the river for navigation. A lock would be constructed at the north end of St. Johns to permit traffic to leave the canal and enter the main channel of the river. Traffic would then re-enter the canal at a new lock to be constructed just upstream of Fryers Island dam. The Fryers Island dam would be operated to improve navigation depths upstream under low water conditions. If this plan is adopted, Fryers Island dam would be so used commencing with the 1973 navigation season. During the spring runoff period, the dam would be left completely open. Experiments are being carried out at low heads at the Fryers Island dam to determine the effect of such operation on channel and lake levels. 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 48 - 3 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 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 regulations 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 regulations 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 and 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 Internationl 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 International Lake Ontario Board of Engineers, were assigned to the Board of Control. Members of the Board for fiscal year. The Canadian members were: Mr. D. M. Ripley, Director, Marine Hydraulics Branch, Department of Transport, Chairman, Canadian Section; Mr. J. B. Bryce, Hydraulic Engineer, Hydro-Electric 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, U. S. Section; Mr. T. M. Crum, Deputy to the Chief, Division, of Licensed Project, Federal Power Commission until March 1971 when he retired and was replaced by Mr. M. E. Thomas; Mr. R. D. Conner, Assistant Resident Manager, Power Authority of the 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 Division Engineer until September 2, 1970 when he was succeed by Colonel W. G. Stewart who in turn was succeeded on December 15, 1970 by Major General E. Graves. Operations during fiscal year. The Board met in Cornwall, Ontario on September 15, 1970 and presented its Thirty-Fourth Progress Report to the Commission on October 6, 1970; met in Alexandria, Virginia on April 5, 1971 and presented its Thirty- Fifth Progress Report to the Commission on April 5, 1971. The Board approved the Thirty-Second and Thirty- Third reports by its St. Lawrence Committee on River Gaging, a Committee which provides and maintains a comprehensive program for recording river levels and flows. The Power Entities have installed the necessary gages requested to date and the required records are being obtained. The Committee keeps the Board advised regarding the gaging program. The levels and outflows have continued to be regulated in accordance with the Commission's directive of April 8, 1960 that, commencing on April 20, 1960, the St. Lawrence project be so operated as to conform to the criteria and other requirements of the Commission's Orders of Approval dated October 1952 and July 2, 1956. Regulation Plan 1958-D is the plan currently approved by the Commission for use by the Board in consulting with the Power Entitites and other interests concerned in compliance with the criteria and other requirements of the Orders of Approval. The supplies to the Great Lakes have remained generally favorable during the reporting period. There were no violations of the approved range of stage during the reporting period. Under its discretionary authority, with continuing guidance from the Commission and with advice from the interests involved, the Board has regulated the Lake Ontario outflow to best meet the requirements set forth in the Orders of Approval. In some instances this has involved storage of water by flowing less than minimum flows under the present regulation plan; in other instances water has been taken from storage. Peaking tests were continued throughout the period and ponding was authorized during the non-navigation season. Interim reports from the Power Entitites showing effects of the flow variations on water levels upstream and downstream of the Barnhart Island Powerhouse were received regularly by the Board in accordance with one of the conditions permitting the tests. There has been no system emergency requiring additional flow during the winter season. There were some ice problems during the reporting period in the Montreal area and downstream during the spring ice break-up period. The Board continued to exercise its discretionary authority by approving flow deviation to assist ice breaking operations during April 1971 in the Beauharnois Canal. The Board Chairmen received copies of a report entitled "St. Lawrence River Flow Distribution Around Cornwall Island 1970," containing the results of the field and engineering work conducted by the U. S. Army, Engineer District, Detroit, and the Water Survey of Canada at the request of the Seaway Entities. This matter is under consideration by the Board. The Commission in its Order of Approval dated December 31, 1968, approved the request for diversion of water from Lake St. Lawrence by the Raisin Region 48 - 4 MISCELLANEOUS CIVIL WORKS Conservation Authority for a temporary period of time. The Board reviewed documents submitted by Deleuw, Cather Company of Canada, relating to the proposed diversion works to be constructed at Long Sault, Ontario, by the Raisin Region Conservation Authority. The Board Chairmen recommended to the Commission that approval be given to the contract drawings as submitted for the work, but cautioned that this approval should not be construed as acceptance of any responsibility regarding the adequacy of the works to pass the requisite amount of water, particularly during low stages of Lake St. Lawrence. The Board has noted the possiblity in the event that the navigation season is extended on the St. Lawrence River 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, by Memorandum of April 8, 1970, to take this matter under consideration and submit a brief thereon. The Board considered the Group's report on this subject, dated July 3, 1970. The Board transmitted this report to the Commission by letter dated September 17, 1970. The Commission agreed to transmit the report to the St. Lawrence River Navigation Authorities. The Commission agreed that further detailed study of the problem of winter navigation and ice booms would be necessary as a consequence of an application to the Commission to change the existing Orders of Approval. However, no such study would be initiated by the Commission or the Board unless such application is made. 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 were the Division Engineer, U. S. Army Engineer Division, North Central, Chairman, U. S. Section; and Mr. T. M. Crum, Federal Power Commission until his retirement in March 1971 when he was replaced by Mr. M. Frank Thomas, Chief, Division of Licensed Projects, Federal Power Commission. Brigadier General W. W. Watkin, Jr. was North Central Division Engineer, until September 2, 1970 when he was succeeded by Colonel W. G. Stewart, as Acting Division Engineer, who in turn was succeeded on December 15m 1970 by Major General E. Graves. The Canadian members were Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, Chairman, Canadian Section and Mr. G. Millar, Chief Engineer, Harbors and Rivers Engineering Branch, Department of Public Works. Operations during fiscalyear. The Board met in Niagara Falls, New York on September 9, 1970, presented its Thirty-Fifth Progress Report to the Commission on October 6, 1970, met in Ottawa, Ontario on October 6, 1970, in Niagara Falls, Ontario on March 18, 1971, and presented its Thirty-Sixth Progress Report to the Commission on April 6, 1971. A report entitled "Use of Measuring Section above Robert Moses Trailrace for Continuing Measurements of Flow Through the Maid-of-the-Mist Pool" was prepared for the Board by its Working Committee. The Board approved of the report's recommendation for the installation of a cableway upstream from the Robert Moses Trailrace, with construction to be carried out by the Power Entities and the design and supervision of the work to be provided by personnel of the Water Survey of Canada and the Corps of Engineers. The cost of installation and first year maintenance and operation of the cableway installation will be borne by the Power Entities through existing arrangements in each country with regard to the carrying out of such stream gaging operations. Plans for construction of the cableway have been initiated. The Board received a Working Committee report entitled "Study of Effect of Fill Structures and Dikes in the Upper Niagara River," dated October 2, 1970. The Working Committee is continuing this study of the effect on river levels utilizing a hypothetical large-scale filling situation along both shores of the Niagara River from the downstream end of Grand Island to Lake Erie. A review of existing procedures regarding the issuance of permits for fills and structures is underway. By Supplementary Order dated October 3, 1969, the Commission amended its Order of Approval of June 9, 1964 in the matter of the Niagara River-Lake Erie ice boom which provides flexibility for closing date of the boom in the fall and its opening date in the spring in accordance with weather and- ice conditions. The ice boom was fully reinstalled on December 15, 1970. At its March 18, 1971 meeting the Board reviewed with local interests concerned the then existing ice situation on Lake Erie. Afterwards the Board advised the Commission that the opening of the boom might be commenced on or after April 18, 1971 and that it would closely monitor the weather and ice conditions on Lake Erie and the Niagara River. At its appearance before the Commission on April 6, 1971, the Board advised that the opening of the boom should be delayed because of the large amount of ice remaining on the lake. The Commission accepted these recommendations. On April 27, taking into account the raising air temperature, the Board further recommended and the Commission ordered the opening of the boom beginning May 3, 1971. Complete removal was accomplished by May 14, 1971. A number of allegations were reported in the spring of 1971, claiming that the retention of the ice boom to such a 48 - 5 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 late date caused modifications to the local weather conditions. However, no basis has been established to prove such allegations. The experience gained during the 1970-71 operations of the boom beyond the first Monday in April, as formerly specified, was beneficial again 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. The Board has requested its Working Committee to prepare a report for later submission to the IJC covering the operation of the Lake Erie Ice Boom during the past winter season. The allegations of weather modification in the locality of the ice boom will be included. During the year the gates in the control structures 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 encountered no unusual maintenance problems during the year. The American Falls International Board, in cooperation with the International Niagara Board of Control, conducted tests on June 4 and 5 1971 to assess the aesthetic effects of increasing the proportion of the total Falls flow which passes over the American Falls. The Commission approved this procedure provided that the terms of the 1950 Treaty were not violated. A new rating curve is being prepared for water level gage on the American Falls channel. The Inland Waters Branch of Canada installed a "Westinghouse Leading Edge Flowmeter" at the Canadian Customs Dock at Fort Erie on the Niagara River. This meter, which is of an accoustic type, was purchased for experimental purposes. Measurements were made for calibration of the meter which is intended to provide a continuance measure of the discharge from Lake Erie. The Commission in 1969 requested the Board to investigate a requests by the West Side Rowing Club of 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 completed its investigation and presented its report dated July 24,.1970 with the conclusion was that the problems experienced by the Rowing Club are a result of the natural variations and that there is no noticeable difference between rowing conditions before and after the ice boom was constructed. 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 l anuary 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 am and 10 pm EST from April 1 to September 15, and 8 am to 8 pm 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 histroy 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 it's Annual Report for 1955. Members of the Committee for fiscal year. The Committee consists of two members. The Canadian representative was Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, and the U. S. representative, was the Division Engineer, U. S. Army Engineer Division, North Central. Brigadier General W. W. Watkin, Jr., North Central, was Division Engineer until he was succeeded by Colonel W. G. Stewart on September 2, who in turn was succeeded by Major General E. Graves on December 15, 1970. 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 48 - 6 MISCELLANEOUS CIVIL WORKS 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 and to assure compliance with all provisions of the Treaty. 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 rewatering of the Falls in November 1969. These inconsistencies which have been attributed to modifications made to the gage intake at the time the American Falls channel was dewatered, require a precise recalibration of the installation. Efforts to finalize a new rating curve by means of discharge measurements were continued during the year. A series of measurements were made by the Buffalo District, Corps of Engineers during November and December 1970. Additional measurements were made during the field test of variation of flow over the American Falls, on June 4 and 5, 1971. The new rating curve derived from these measurements was considered unsatisfactory. It has been decided to move the gage from its present location upstream to provide a better position for the intake. This will allow a more satisfactory rating curve to be obtained. 2H. AMERICAN FALLS INTERNATIONAL BOARD Constitution and duties. In a Reference dated March 31, 1967, the Government 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 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, U. S. Army Engineer Division, North Central, Chairman, U. S. Section; and Mr. G. Eckbo, Chairman, Department of Landscape and Architecture, University of California, Berkeley. Brigadier General W. W. Watkin, Jr. was North Central Division Engineer until September 2, 1970, when he was succeeded by Colonel W. G. Stewart, who, in turn, was succeeded on December 15, 1970 by Major General E. Graves. Canadian members were Mr. T. M. Patterson, Special Advisor, Department of Energy, Mines and Resources, Chairman, Canadian Section, and Mr. H. S. M. Carver, Chief Advisory Group, Central Mortgage and Housing Corporation, Ottawa, (Retired). Operations during fiscal year. The U. S. Army Corps of Engineers received study funds of $145,000 for the fiscal year. Departments of the Canadian Government funded operations of their personnel who are involved in Board and Committee activities. The expenses of the representative of the two Park Commissions have been borne by the respective Park Commission. Subsequent to the dewatering of the American Falls, the geologic studies have continued. The existing instrumentation to measure subsurface water levels and mass rock movement were read periodically. The stratigraphic, structural and rock mechanics studies are still in progress. Instruments were installed in two core holes and on the bedrock surface in the inspection trench on Luna Island to provide information on mass movement in the rock for use in understanding the mechanism of failure as well as to monitor winter effects. Essentially all laboratory testing of rock cores is completed. A hydraulic model of the Falls for use in developing alternative aesthetic treatments of the talus was started and completed during the reporting period. The aesthetic members of the Board and Working Committee continue to uitilize the model which has proved to be a very useful tool in their studies. The Board has furnished the Commission copies of a report entitled, "Feasibility Study of a Structure to Control Levels of the Maid-of-the-Mist Pool," dated September 1970. The report concluded that it is feasible to build a control structure in the lower Niagara River to raise the water level of the Maid-ofthe- Mist Pool to levels which existed prior to diversion of water for the population of power authorized by the Niagara River Treaty of 1950. This raising of the water levels would cover part of the talus accumulation at the foot of the American Falls and submerge portions of the rock ledges on the pool foreshores. The cost of the structure would range from 10 to 20 million dollars. Before any final design for a selected site would be made, an extensive ice study should be conducted to assess the effects of the structure on the existing river ice regime. Regarding the behavior of ice in the Maid-ofthe- Mist Pool, the Board began such a study. An Ice Advisory Group has been formed to lay out a program of data collection and evaluation. During the winter of 1970-71 data collection was carried out. The Board asked its Working Committee to prepare a report concerning the items immediately adjacent to the Falls which detract from the view from both sides of the Niagara River. A report entitled, "Niagara Falls - Removal of Scenic Blight and Improvement of its Environment," resulted. Later, the Commission asked the Board to report on any threatened intrusions upon the views of the Falls. The Board, by letter dated 48- 7 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 December 2, 1970, forwarded to the Commission a report entitled, "Intrusions on Views of Niagara Falls." This report recommended that an international body should be established to set privileges that might be followed by domestic authorities, for controlling the visibility of structures in the immediate vicinity of the Falls. No new developments have occurred concerning the "Proposed Study of the Environment of the Niagara Falls." However, an environmental design study for the Niagara River area has been undertaken by the Erie and Niagara Counties Regional Planning Board and is funded by the U. S. Department of Housing and Urban Development, State of New York and the Erie-Niagara Counties. The study is covering all the political subdivisions along the Niagara River on the U. S. side. A final report is scheduled for the fall of 1971. Since 1967, the date of the formation of the Board, evidence of new rock weakness has been discovered. As a result, there is a serious concern about possible rockfalls endangering the public. The Niagara Frontier State Park Commission requested the Board to extend the limits of its investigatory program to include the gorge wall north of the Falls' flank at Prospect Point, Luna Island and the Goat Island flank of the American Falls, and Terrapin Point, the Goat Island flank of the Horseshoe Falls. The Board concluded and the Commission confirmed that extension of its investigatory work was warranted and permissible in these areas with the exception of Terrapin Point considered beyond the extent of the 1967 Reference. By Reference dated October 1, 1970 and October 5, 1970, respectively the governments of Canada and United States requested the Commission to extend the investigation to include the flank areas of the American Falls and of the Goat Island flank of the Horseshoe Falls endangered by the possibility of erosion and other geological conditions. Additionally, the matter of safety of persons viewing these areas was also specified. The Commission also extended the Board's investigatory responsibilities to cover Terrapin Point and to include the subject of public safety there and in the vicinity of the American Falls. In response to the requested extended investigations a revised plan of study based on the current level of funding was prepared which includes a work schedule and cost estimates for installing safety instrumentation. The expanded investigation will also obtain additional geologic information from the American Falls flank area and Terrapin Point, and other studies necessary for a final report to be completed by December 1974. The Board briefed the news media on the various aspects of its studies on November 9, 1970. Media representatives expressed satisfaction with the conference and requested that similar briefings be held. The Board instructed its Working Committee to again brief the news media at the site of the Falls hydraulic model at Islington, Ontario. This briefing took place on June 16, 1971 and was very successful. 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. 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 Committeee 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 regulations 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, regulation plans are developed; necessary economic, 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 assess hydrologic, economic and qualitative effects for regulatory work recommended. Members of the Board for fiscal year. United States members of the Board were Mr. L. G. Feil, Retired, Office, Chief of Engineers, U. S. Army, Chairman, 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, Canadian Section; Mr. C. K. Hurst, Chief, Maintenance and Operations, Harbors and Rivers Engineering Branch, Department of Public Works; and Mr. R. H. Smith, Acting Director, Hydraulics Study Division, Department of Transport. The Working Committee consists of four members representing the United States and three representing Canada. U. S. members of the 48 - 8 MISCELLANEOUS CIVIL WORKS Working Committee were the Division Engineer, U. S. Army Engineer Division, North Central, Chairman, U. S. Section; Mr. M. Abelson; Mr. M. 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. Brigadier General W. W. Watkin, Jr. was North Central Division Engineer, until September 2, 1970, when he was succeeded by Colonel W. G. Stewart who, in turn, was succeeded on December 15, 1970 by Major General E. Graves. 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, Canadian Section; Mr. D. W. Quinlan, Manager Construction and Engineering, Department of Public Works; and Mr. C. J. R. Lawrie, Marine Hydraulics Branch, Ministry of Transport. The six subcommittees have been formed with membership drawn from agencies participating in the study and represented on the Board and Working Committee. Operations during fiscal year. Work has been completed on a series of preliminary plans for the coordinated regulation of Lakes Superior and Ontario. The plans were developed to meet a number of alternative sets of regulation objectives. The results of these plans were incorporated in a preliminary SO report entitled "Regulation of Lakes Superior and Ontario," dated February 18, 1971. The Board met with the Commission on March 12, 1971 and presented a summary on its findings and details of the SO Report. The Commission approved the Board's recommendation to proceed with the development of a refined Plan of Regulation for Lakes Superior and Ontario. Such refinement will have as its objective the reduction of net losses to any interest wherever possible. Work is also continuing on preliminary four-lake and three-lake regulation plans. One of the objectives of the four-lake plan is to achieve the restoration of the levels of Lakes Michigan-Huron during low supply periods to the pre-1933 outlet conditions, without incurring detrimental effects during high supply periods. This approach will investigate the possibility of substituting a regulating structure for planned fixed compensating works (sills) in the St. Clair River. An investigation for increasing the flexibility of Lake Superior regulation is continuing, specifically, to determine the ability to pass winter flows in excess of 85,000 cfs. A comparision 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 third period of experimental operation of the gates of the Lake Superior Control Works at Sault Ste. Marie took place during the 1970- 71 winter with an outflow to 95,000 cfs. Because of the increased water levels in the lower St. Marys River, the test operation was curtailed on January 28, 1971. It is planned to continue the test during future winters to verify the feasibility of passing a flow of 95,000 cfs under a variety of winter conditions. The navigation season in the St. Marys River was extended by approximately three weeks over the preceding year. The last commercial vessel transit of the St. Marys River was made on January 30, 1971. The navigation season extension complicated the analysis of the higher flow winter tests. Development of preliminary criteria for regulation continued. The preliminary criteria will be subject to considerable subsequent modification as a result of future economic evaluations and further considerations in regard to the requirements of the various interests concerned with lake regulation. Regulatory Work design and cost studies were continued. Subsurface investigations for the potential sites for structures and channel excavations for the St. Clair-Detroit River system were completed. The St. Clair River mathematical model was used to determine dredging volumes of channel capacity increases and also to develop a series of schemes with various numbers of structures to control the flow. The Detroit River mathematical model is being refined for more efficient computer operation. Preliminary design for the Niagara River control structure at the lower site was initiated. A report on the subsurface investigations at the downstream site for the control structure in the Niagara River was completed. A number of briefing meetings were conducted by various subcommittees which were attended by Federal, Provincial and State representatives of fisheries, wildlife and pollution control interests. The primary objective of the meetings were to provide these representatives with broader understanding of the problems, and alternate solutions to problems of lake regulation and to stimulate State and Provincial input into the controversial areas of structures and criteria for regulation. The Boards 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 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 48 - 9 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 Subcommittee and the Lake Level Subcommittee were formed to assist the Coordinating Committee in its work. Subsequently, a fourth subcommittee, designated the Physical Data Subcommittee, was formed. The Vertical Control and Lake Level Subcommittees were combined into one Subcommittee in 1969. These subcommittees have been conducting 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 District, Detroit, and Mr. F. A. Blust, Chief, Engineering Division, Lake Survey Center, National Ocean Survey, Department of Commence. Members for Canada were Dr. A. T. Prince, Director, Inland Waters Branch, Department of Energy, Mines and Resources, Chairman, Canadian Section, Mr. D. M. Ripley, Director, Marine Hydraulics Branch, Department of Transport and Mr. D. F. Witherspoon, Great LakeySt. Lawrence Study Office, Department of Energy, Mines and Resources. Operations during fiscal year. The River Flow Subcommittee completed the work on the Lake Superior outflow report. A study of rating of the compensating works in the St. Marys River was continued, and also a study of St. Clair River flows was continued. The Vertical Control and Lake Level Subcommittee completed the final report on Lake Erie water level gage histories. Work was continued on preparation of gage histories for Lakes Michigan-Huron and the St. Clair- Detroit River. Leveling for the updating of IGLD (1955) was completed between Fort Niagara, New York on Lake Ontario, and Sturgeon Point, New York on Lake Erie and between Monroe, Michigan on Lake Erie and Harbor Beach, Michigan on Lake Huron. Operation of seasonal gages on the Lakes Superior and Michigan for crustal movement studies was continued. The Physical Data Subcommittee continued work on determining the water volumes of Lakes Huron and Superior. Work was started on the coordination of shoreline mileages of the Great Lakes. 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. Its primary purpose is to facilitate the exchange of information and to provide informal coordination amoung 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. During the year the United States Chairman was Mr. H. F. Lawhead, Acting Chief, Engineering Division, U. S. Army Corps of Engineers, North Central Division; Mr. S. H. Fonda, Jr., Chief, Great Lakes Hydraulics Branch, North Central Division; Mr. R. J. Schneider, Water Quality Office, Environmental Protection Agency, Region 5, (replaced by Mr. C. Risley of the same agency in April 1971); Dr. D. C. Chandler, Director, Great Lakes Research Division, University of Michigan; Colonel L. J. Goodsell (retired), Executive Director, Great Lakes Commission and Mr. L. T. Crook, Director of Planning, Great Lakes Basin Commission. The U. S. Section of the Steering Committee was modified on April 27, 1971 to include members from the following agencies: Corps of Engineers, Lake Survey Center-NOAA, Great Lakes Basin Commission, Michigan Water Resources Commission, University of Michigan, and State University of New York at Buffalo. The new U. S. Chairman is Mr. L. T. Crook, from the Great Lakes Basin Commission. The Canadian members of the Group were Dr. A. D. Misener, Director, Great Lakes Institute, University of Toronto; Mr. T. L. Richards, Meteorological Service of Canada, Department of Transport; Mr. J. P. Bruce, Director, Canada Centre for Inland Waters; Dr. A. M. McCombie, Ontario Department of Lands and Forests and Mr. F. A. Voege, Assistant General Manager, Ontario Water Resources Commission. Operations during the fiscal year. The coordination of research activities was maintained during the year. The Data Processing Subcommittees' activities continued. A Subcommittee paper, "The Canadian Directory and Project Forecast for 1971 ", was prepared and distributed. The "U. S. Directory and Project Forecast for 1971" suffered delay and was to be published late in 1971. Also proposed is a Directory of Subject Thesis concerning the Great Lakes and work on this is underway at the various Universities and Institutes. The Study Group has continued its effort to coordinate activities of most or all agencies concerned with the Great Lakes. Ships and Facilities Schedules Subcommittee activities continued. The Navigation Subcommittee continued its activities. During the year the Study Group met in Burlington, Ontario on November 17-18, 1970 and in Ann Arbor, Michigan April 27-28, 1971. At these meetings, the Federal State, Provincial, and University activities were reported and discussed for the awareness of all. 48 - 10 MISCELLANEOUS CIVIL WORKS 2L. 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 feet. 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 for Canada. The Division Engineer, U. S. Army Engineer Division, North Central was the United States member. Brigadier General W. W. Watkin, Jr. was Division Engineer, until succeeded by Colonel W. G. Stewart on September 2, 1970 who, in turn, was succeeded on December 15, 1970 by Major General E. Graves. 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 in the area 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 Ste. Marie 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. Changes 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 the period July through November 1970 the Lake Superior Board withheld about 80,000 cfsmonths 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. Because of below normal lake levels during the early part of the year, the additional flow requirements for the 1970-71 tests were estimated to be equivalent to 125,000 cfs-months of water to permit an outflow of 95,000 cfs over the entire winter period as compared to an anticipated rule curve requirement of 70,000 cfs. However, with exceptional high supplies late in the year, lake levels rose to above normal conditions which indicates a rule curve outflow of 85,000 cfs for the winter period. The Board, therefore, terminated in November the storage of additional water for the tests, and even discharged an additional water for the tests, and even discharged an additional 16,000 cfs-months above rule curve requirements during the period 1-16 December 1970 in order to reduce the amount of water which had been stored for test purposes. The winter test operations were conducted at Sault Ste. Marie control works in the St. Marys River as part of the investigation being carried out by the International Great Lakes Levels Board which is studying the feasibility of discharging successfully 95,000 cfs under a greater variety of winter conditions than those which prevailed during the 1969-70 winter season. Detailed arrangements were made for continuous monitoring of the water levels in the lower St. Marys River. Approval from the Great Lakes Power Corporation, which owns the Canadian portion of the control structure, was obtained for the winter operation of these gates for the test program. The test began on December 16. 1970 with an outflow of 95,000 cfs. But during January 1971 a steady increase in the water level was registered at the U. S. Powerhouse Tailrace gage. This level was approximately maintained until January 25, at which time a further build up began, reaching a peak on January 28. As this elevation was approaching the critical level where flooding of the generator pits on the U. S. side would occur, the Board decided to reduce the flow of about 85,000 cfs by the closure of 3 gates. This lowered the water level at the U. S. Powerhouse tailrace gage to an acceptable level on the following day. It is believed that the problem was created by an accumulation of ice under the cover below the rapids. The navigation season in the St. Marys River was extended until January 30, 1970. This represents almost a three-week extension over last year. The season extension complicates the analysis of the winter test conducted by the Board. It is not known what relationship that navigation may have contributed to the difficulties encountered in discharging 95,000 cfs. On .March 9, in view of the reduced slope in the river and the consequent lessening danger of upstream flooding and because of the high levels on Lake Superior, the Board opened one additional gate returning the flow to the regulation plan maximum of 85,000 cfs. This premature termination of the test left approximately 60,000 cfs-months of water in storage. Necessary compensating work pier maintenance, which was deferred in previous years due to high water of Lake Superior, was initiated in both United States and Canada by contracts during the summer of 1970. On the United States side in 1970 all repairs were to pier 13. This pier had suffered considerable deterioration on the top and all sides. Repairs consisted of removing deteriorated concrete by chipping, particularly at the nose and in the vicinity of the water line, and restoring the pier to its original condition by placement of Prepakt Concrete. On the Canadian side, maintenance work by the Great Lakes Power Cor- 48 - 11 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1971 poration included (1) the repair of the north abutment of the control structure and piers 1 to 4 inclusive, and (2) the repair of the embankment immediately north of the north abutment and, continuing northward, the causeway that extends generally from the control structure to the railway embankment at the north end of the railway bridge. Representatives of the Board members visited the site of the compensating works on October 1, at which time the repair works were progressing satisfactorily. The Board made an inspection of the repair works on October 19. On November 3, the U. S. Board member and other Corps of Engineers representatives visited the site. Several letters written on behalf of property owners on the United States side of the lake were received by the U. S. member of the Board concerning high water conditions on the lake during the year. Appropriate replies were communicated in each case. 2M. INTERNATIONAL PRAIRIE PORTAGE BOARD OF CONTROL Constitution and duties. The International Prairie Portage Board of Control was formed by International Joint Commission for purpose of furnishing it with technical advice regarding suitability of a dam structure at Prairie Portage, Lake County, Minn. After approval of plans by Department of the Army and the Commission, the Board was retained to advise the Commission further regarding progress of construction and any other matters which might arise concerning this project. 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 had been functioning satisfactorily at the control dam for the lakes. 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. C. I. McGinnis, District Engineer, U. S. Army Engineer District. St. Paul, represented the United States. Operations during the fiscalyear. On April 22, 1971, the United States Forest Service informed that they have submitted a request for $100,000 for construction and $10,000 for contract administration and necessary overhead costs. However, due to the.shortage of funding in recent years, they are not optimistic that this amount of money will be made available this fiscal year. The Forest Service has completed the construction drawings and specifications for the permanent control structure; however, because this structure is in the Boundary Waters Canoe Area, the supplemental specifications must be added covering such items as when the contractor will be allowed to work, the types of equipment and transportation methods he will be allowed to use, etc. 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 . . . is 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 Commission on October 2, 1962 and April 5, 1967, respectively. On July 29, 1970, the Supplementary Order in the matter of emergency regulation of Rainy Lake and of the Boundary Waters in the Rainy Lake Watershed was approved by the Commission. Since that time, Rainy and Namakan Lakes have been operated in accordance with rule curves prescribed by this Supplementary Order. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Engineer, Inland Waters ranch, Department of Energy, Mines and Resources, represented Canada, and Col. C. I. McGinnis, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. Slightly higher than normal inflows and outflows occurred at Namakan and Rainy Lakes throughout July, but receded to normal flows in August and September. Heavy rains in October and November resulted in outflows considerably higher than normal. Namakan Dam was opened wide on 26 November and remained wide open throughout the winter and throughout spring breakup until 11 June when the gates were partially closed to insure reaching full pool by 20 June. Higher than normal discharges also occurred at Rainy throughout the winter. During the spring breakup, the runoff was easily controlled within the limits of the prescribed rule curves. On April 2, 1971 Colonel McGinnis with one staff engiieer and the Canadian member of the Board 48 - 12 MISCELLANEOUS CIVIL WORKS of Control met with local residents in the vicinity of International Falls to arrive at the best solutions to operating problems. Although inflows and outflows of both Namakan and Rainy Reservoirs were the highest of record for the winter period, little difficulty in operating was encountered. Studies the past year by the Control Board have resulted in proposed revision of the rule curves. 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 above elevation 1061 feet or falls below elevation 1056 feet, 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 C. I. McGinnis, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. The Control Board maintained supervision to insure that every effort was being made to comply with the provisions of the Convention. On July 1, 1970, the level of Lake of the Woods was above 1061.0 feet and was, therefore, under the immediate supervision of the Control Board. The power plants and dam at the outlet of Lake were wide open and discharging in excess of 47,000 cfs. They remained wide open until 20 July when the level receded below 1061.0 and the supervision reverted to the Canadian Lake of the Woods Control Board. Normal inflows and outflows occurred the rest of the summer. By early November, heavy participation caused high inflows and resultant high outflows. High outflows continued throughout the winter until the spring breakup. The spring runoff was easily contained within the reservoir without excessive flows and on June 30, 1971 a stage of approximately 1060.0 with an outflow of about 13,000 cfs occurred. On January 28, 1971, Colonel McGinnis and one engineer attended the meeting of the Canadian Lake of the Wood Control Board in Toronto. On April 1, 1971, Colonel McGinnis and one engineer together with the Canadian Board member attended an open meeting with local interests at Warroad, sponsored by the Control Board to discuss levels on Lake of the Woods. The above meetings were cooperative efforts of the Control Board to arrive at the best solution for the operating problems. 2P. INTERNATIONAL PEMBINA RIVER ENGINEERING BOARD Constitution and duties. The Board was established April 3, 1962 by the International Joint Commission to investigate and report upon the measures which could be taken to develop the water resources of the Pembina River, Manitoba and North Dakota, and to reduce recurring flood losses in the basin. Members of the Board for fiscal year. The Board consists of six members. The Canadian representatives were Mr. J. G. Watson, Chief Engineer, Department of Regional Economic Expression, Department of Agriculture, Regina, Saskatchewan, Chairman, Canadian Section; Mr. R. H. Clark, Chief, Engineering Division, Inland Waters Branch, Department of Energy, Mines and Resources, Ottawa, Ontario; and Mr. N. H.

Burnham, District Chief, Water Resources Division, U. S. Geological Survey, Boise, Idaho, for the United States. Operations during fiscal year. Although no formal meetings of the Board were held during the fiscal year Mr. Paget and Mr. Ramsden made inspection visits to the area. An annual report was submitted to the Commission. The Board reported that Cominco Ltd., operated the control works at Corra Linn Dam under the provisions of the Order of the Commission dated November 11, 1938, allowing for a maximum winter storage elevation in Kootenay Lake of 1,745.32 feet and regulated the level of Kootenay Lake within the prescribed limits of the Order with natural lake level at zero on August 19, 1970. With the buildup of storage for winter use, the lake rose to a maximum of 3.8 feet above the computed natural level on 16 snf 17 November and was 3.3 feet above computed natural level on 31 December. Storage at Duncan Dam affected the inflow to Kootenay Lake. The levels of Kootenay Lake under 1929 outlet conditions (called natural conditions) were computed without including the storage changes in Duncan Lake. Streamflow measurements have been made regularly throughout the year by the United States Geological Survey and by the Water Survey of Canada. The West Kootenay Power and Light Company has continued to supply the Board and other agencies involved with complete records of the regulation of Kootenay Lake as affected by the operation of the Corra Linn Dam and power plant. The preliminary Flood Control Operating Plan 48 - 14 MISCELLANEOUS CIVIL WORKS for Libby Dam storage under the Columbia River Treaty is still being studied by the Columbia River Treaty Entities. Present indications are that Libby storage can be utilize, at least until Libby at-site generation is installed, without creating water flow conditions which would make it impossible for West Kootenay Power and Light Company to comply with the Kootenay Lake levels specified in the existing IJC order. When and if a Libby Operating Plan is recommended which prevents compliance with the existing IJC order, an application for a revision will be submitted to the IJC. It is not yet clear who would submit the application but it may be the Seattle District Engineer. The discharge control works at the outlet of Duck Lake were operated during the year in accordance with the Orders of Approval of the Commission. The gates of the Duck Lake outlet works were opened on 15 August when the elevation of Duck Lake was 1,743.98 and the elevation of Kootenay Lake at Queens Bay was 1,743.46 feet. The gates were kept open until 5 September when the elevation of Duck Lake was 1,743.82 and the elevation of Kootenay Lake at Queens Bay was 1,743.41, thereafter the gates were closed for the remainder of 1970. 2S.
