At the eastern end of Lake Erie, at the head of Niagara River, 176 miles easterly from Cleveland, Ohio. (See U. S. Lake Survey Charts Nos. 3 and 314.) Previous projects.-The original project was adopted by River and Harbor Act of May 20, 1826, with modifications by River and Harbor Acts of July 7, 1838, June 23, 1866, June 23, 1874, June 3, 1896, March 2, 1907, and June 25, 1910. For further details see page 1967 of Annual Report for 1915 and page 1606 of Annual Report for 1938. Existing project. This provides for the following: (a) An outer harbor about 411⁄2 miles long and 1,600 feet wide, formed by a breakwater system approximately parallel to the lake shore extending from Stony Point to the head of Niagara River and having a total length of 23,704 feet, with entrances near the north and south ends, and consisting of the Stony Point breakwater (including the south entrance arm) 3,603 feet long; the south breakwater 10,289 feet long; the old breakwater 7,608.5 feet long; the north breakwater 2,203.5 feet long; a south entrance 550 feet wide; a centrally located circulation gap about 150 feet wide and natural depth of 20 feet; and a north entrance 1,300 feet wide. The types of construction are as follows: 9,550 linear feet of rubble-mound; 14,154 linear feet of timber-crib substructure surmounted with 9,113 linear feet of concrete 370.5 linear feet of stone, and 4,670.5 linear feet of stone-concrete superstructure. (b) A south pier at the entrance to the inner harbor (Buffalo River,), 1,760 feet long, of timber-cribs and piles with concrete and stone superstructure. (c) A depth of 25 feet in the south entrance and the portion of the outer harbor south of a line perpendicular to and 2,000 feet north of the southerly end of the south breakwater and a depth of 23 feet north of that line, with the westerly project limit 150 feet from the axes of the breakwaters and the easterly project limit 50 feet from the United States harbor line; and removal to a depth of 27 feet of three small shoals located on the direct route of approach to the south entrance. (d) A north entrance channel 800 feet wide with a depth of 25 feet in earth and 26 feet in rock from deep water in the lake to the outer harbor; and a depth of 22 feet in earth and 23 feet in rock in the Buffalo River entrance channel from the outer harbor to the junction of Buffalo River and Buffalo Ship Canal, with the southern project limit 5 feet from the south pier and the northern project limit 40 feet from the dock of the Delaware, Lackawanna & Western Railroad Co. (e) Channels in Buffalo River and Buffalo Ship Canal with depths of 22 feet in earth and 23 feet in rock to the upper Delaware, Lackawanna & Western Railroad Co. bridge and to the Lehigh Valley Railroad canal, respectively, with widths generally of 150 and 125 feet, respectively, without dredging closer than 25 feet to dock lines except at bends, and with the rock ledge just above the Ohio Street Bridge cut back approximately 13 feet. The project depths are referred to low-water datum for Lake Erie, elevation 570.5 feet above mean tide at New York. Ordinary fluctuations of water surface are from 3.5 feet above to 0.5 foot below low-water datum, and extreme fluctuations due to wind and other causes about 9 feet above and 312 feet below the plane. The estimate of cost for new work, revised in 1949, is $16,146,000 exclusive of amounts expended on previous projects. The latest (1949) approved estimate for annual cost of maintenance is $290,000. The existing project was authorized by the following river and harbor acts: July 25, 1912 July 3, 1930 Aug. 30, 19353 Aug. 30, 1935 Dredging at entrance to canals at South Buffalo in Extension of Federal project to Commercial Street Deepening areas, A, B and D, in outer harbor to 21 Extension of south entrance and south breakwaters Maintenance of channels in Buffalo River and Buf- Mar. 2, 1945 Deepening the north and Buffalo River entrance 1 Completed under previous projects.

Doc. 352, 78th Cong., 1st sess.1 Local cooperation.-Deepening the south portion of the harbor and the south entrance channel to 25 feet, and removal of the shoals in lake approach to a depth of 27 feet are subject to the condition that local interests afford satisfactory assurances that the improvement of the ore and limestone terminal at the southern end of the outer harbor and the inner channels leading thereto, to fully utilize the increased depth afforded, will be undertaken to an extent sufficient to justify the cost of the improvement by the Federal Government. These conditions have not been complied with. The River and Harbor Act of March 2, 1945, modified the above requirement to permit deepening and maintaining to 23 feet of the shallow, undredged strip along the breakwater and the triangular area in the southerly outer harbor until such time as local interests meet prescribed local cooperation for dredging to 25 feet. All other conditions have been complied with. Terminal facilities.-There are approximately 50 terminals for the handling of all types of cargoes. The most important cargoes handled are iron ore, coal, grain, limestone, sand and gravel, steel products, scrap, flour, petroleum products, automobiles and sulfur. In general, the terminals operated by the railroads and lake-transportation companies and most of the grain elevators are open to the public. The city of Buffalo owns two wharves, one of which is used as an automobile terminal. The American Shipbuilding Co. has a drydock and facilities for repairing lake vessels. There are also several privately owned marine service, mooring and supply docks for lake vessels and smaller boats. The facilities are considered adequate for the existing commerce. (See Lake Series No. 1, revised 1939, Corps of Engineers.) Operations and results during fiscal year.-New work: Plans and specifications, by hired labor, and dredging and rock excavation, by contract, for deepening of portions of Buffalo River (second stage), were continued at a cost of $559,885.86. Plans and specifications by hired labor for deepening portions of Buffalo River and Buffalo River entrance channel were commenced at a cost of $277.67. Maintenance: Government plant and hired labor made repairs to the south breakwater at a cost of $11,217.65, removed obstructions from the Buffalo River entrance channel, north entrance channel, and outer harbor at a cost of $11,970.10, and removed 95,202 cubic yards of material for restoration of project depths in the Buffalo River entrance channel and outer harbor at a cost of $36,568.96. Maintenance of the Buffalo River and Ship Canal by contract was continued and 127,389 cubic yards of material were removed for restoration of project depths at a cost of $112,110.43. The total cost for the year was $732,030.67, of which $560,163.53 was for new work and $171,867.14 for maintenance. The total expenditures were $725,632.62. Condition at end of fiscal year. The existing project is about 23 percent complete. The Stony Point breakwater was completed in 1899, a 1,000-foot extension was completed in 1914; 1,200 feet of the shore end was sold to the Lackawanna Steel Co. in 1918, and another 1,000-foot extension was completed in 1935. The south breakwater was completed in 1903, and a 300-foot extension was completed in 1935. The north breakwater was completed in 1901, the old breakwater in 1893, and the south pier in 1869. The 23-foot project area in the outer harbor and the north-end entrance channel has been deepened to project depth except for strips 50 feet wide along the harbor line and 180 feet wide between the Superior Grain Corp.'s and the Merchants Refrigerating Co.'s piers. Buffalo River entrance channel has been deepened to 21 feet. The harbor structures are generally in good condition except at various points of the south breakwater and old breakwater where the slope stone on the lakeside has been displaced, portions of the stone banquette on the harbor side of the old breakwater have dropped and the riprap protection along the lakeside of the northerly 1,200 feet of the old breakwater has settled. The controlling depth in the northerly part of the outer harbor is 23 feet and in the north and south entrance channels is 21 feet. Controlling depth in the Buffalo River channel is 20 feet, and in the southerly portion of the outer harbor it is 21 feet, at low-water datum. The work remaining to be done to complete the project consists of the removal to 27 feet of three small shoals on the direct approach to the south entrance, the deepening of the north entrance channel to 25 feet in earth and 26 feet in rock, completion of deepening the Buffalo River entrance and Buffalo River and Ship Canal to 22 feet in earth and 23 feet in rock, and deepening of the 25-foot project area in the southerly part of the outer harbor and the remainder of the 23-foot outer harbor area all to project depths. The total cost of the existing project was $7,294,515.13, of which $3,687,157.35, including $655,500 Public Works funds, was for new work and $3,607,357.78 for maintenance. The total expenditures were $7,199,675.42. In addition there was a cost and expenditure of $390,000 from contributed funds for maintenance. Proposed operations.-The balance unexpended at the end of the fiscal year amounting to $198,923.88, plus accounts receivable of $15,325.42, together with an anticipated allotment of $1,123,000 during fiscal year 1951, a total of $1,337,249.30, will be applied as follows: The sum of $585,000 is needed to be appropriated for the following schedule of work during the fiscal year 1952: New work: Deepen portions of the southerly outer harbor to 23 feet, by contract, July 1951 to June 1952 ..
