REQUIREMENTS OF LOCAL COOPERATION FOR FLOOD-CONTROL PROJECTS

Congress in the Flood Control Act approved June 22, 1936, established, and in the amendatory and supplemental general Flood Control Acts approved August 28, 1937, June 28, 1938, August 11, 1939, August 18, 1941, December 22, 1944, July 24, 1946, June 30, 1948, and May 17, 1950, reaffirmed the general policy that flood control throughout the United States is a proper activity of the Federal Government, in cooperation with the States and local communities, and that the Federal Government should improve or participate in the improvement of navigable waters or their tributaries for flood-control purposes, if such projects are economically justified and if the lives and social security of people are otherwise adversely affected. Those acts also specified the local cooperation required for the projects authorized therein.

These requirements of local cooperation, in brief are as follows:

(a) Dam and reservoir projects authorized in any of the aforementioned flood-control or river and harbor acts are constructed entirely at the expense of the United States and are maintained and operated by the Corps of Engineers. No local cooperation is required for dam and reservoir projects unless specifically prescribed by special provisions of law.

(b) For local flood-protection projects, except channel improvement or channel rectification projects authorized by the acts of 1936, 1937, and 1938, local interests must provide without cost to the United States all lands, easements, and rights of way necessary for the construction of the projects, hold and save the United States free from damages due to the construction works, and maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of the Army. Channel improvement and channel rectification projects authorized by the acts of 1936, 1937, and 1938 are built at Federal expense, and no local cooperation is required. Exceptions to these general rules are provided by law in the case of certain specific projects.

This district comprises southeastern Washington, exclusive of the watershed of the Columbia River and tributaries above and including the Yakima River, Wash.; all of Idaho, except the northern part and a small southeastern portion; a portion of western Wyoming; a small part of northwestern Utah; part of northeastern Nevada and all of eastern Oregon.
District engineer: Col. W. H. Mills, Corps of Engineers, to April 1, 1953; Col. F. S. Tandy, Corps of Engineers since that date.
Division engineer of the North Pacific Division, Portland, Oreg., comprising the Portland, Oreg., Seattle, Wash., Walla Walla, Wash., and Alaska districts: Brg. Gen. O. E. Walsh, United States Army, to Feb. 14, 1952; Col. E.C. Itschner, Corps of Engineers.

NAVIGATION

1. SNAKE RIVER, OREG., WASH., AND IDAHO

Location. The Snake River, which is the largest tributary of Columbia River, rises in Yellowstone National Park, in the western part of Wyoming, flows in a general westerly direction for about 1,000 miles and empties into Columbia River near Pasco, Wash. 324 miles from the Pacific Ocean. (See U.S. Geological Survey maps of Oregon, Washington, and Idaho.)

Previous projects. No formal project for the improvement of Snake River was adopted by Congress prior to the act of June 13, 1902. Subsequent projects were adopted by River and Harbor Acts of June 13, 1902, June 25, 1910 and August 30, 1935. For further details see page 1991 of Annual Report for 1915, page 1849 of Annual Report for 1938 and page 2676 of Annual Report for 1948.

Existing Project. This provides for the construction of such dams as are necessary and open-channel improvement for purpose of providing slack water navigation and irrigation between the mouth of Snake River and Lewiston, Idaho The pool formed by McNary Dam will provide slack water from the mouth of Snake River to mile 9.7. For maintenance purposes the project also provides for any necessary work on the River between Lewiston and Johnson's Bar, Idaho, as authorized under previous projects. No channel dimensions are specified above Lewiston. A system of four dams between the mouth of the Snake River and Lewiston has been approved. The estimated total cost, revised in 1950, including the installation of three power units at each dam is as follows:

Dam 1 Ice Harbor, river mile 9.7 $35,930,000
Dam 2 Lower Monumental, river mile 44.7 118,000,000
Dam 3 Little Goose, river mile 72.2 133,000,000
Dam 4 Lower Granite, river mile 113.1 111,000,000
Total 497,930,000

The existing project was authorized by the River and Harbor Act approved March 2, 1945. (See H. Doc. 704, 75th Cong., 3d Sess.)

Local Cooperation. No conditions were imposed by law.

Terminal facilities. From the mouth of the Snake River to Riparia, 67 miles, there are no wharves or warehouses on the river banks. From Riparia to Lewiston, Idaho, 73 miles, there are no wharves, but there are public and privately owned warehouses and grain elevators located at Penawawa, mile 91.5, Lewiston, mile 140, Asotin, mile 146 and between Asotin and 11 miles above. Just above Lewiston, mile 140.5, there is a privately owned 40- by 60-foot wharf. On the left bank between Riparia and Lewiston there are several wheat warehouses formerly used for storage of wheat to be transferred to the railroad on the right bank.

Operations and results during fiscal year. Reanalysis of design features of the Ice Harbor project, taking account of latest developments in connection with McNary and The Dalles projects, was authorized in July 1952 for the purpose of developing a firm project cost estimate. Pursuant thereto, additional surveys, foundation exploration and design studies for railroad relocations have been undertaken, a new real estate appraisal has been made and general phases of the preliminary design for the project have been completed, including foundation exploration for the right abutment, incorporation of preliminary powerhouse designs of the architect engineer in the project plan and reanalysis and redesign of the fish facilities in accordance with latest developments for these facilities.

Costs for the fiscal year were $131,152.15 for new work and $432.66 for maintenance, a total of $131,584.81. Expenditures were $137,622.25 for new work and $432.66 for maintenance, a total of $138,054.91.

Condition at end of fiscal year. Construction has not been initiated at any of the four dam sites. Engineering and design on Ice Harbor Dam is approximately 18 percent complete. Hydraulic design and model studies have been initiated and the preliminary stage of an architect engineer powerhouse design contract has been completed. Plans and specifications for the first step cofferdam are 75 percent complete. Engineering and design studies for dams 2, 3, and 4 are in a preliminary stage only. Preliminary plans on real estate, flowage, and relocations covering the four dams have been completed and submitted to higher authority.

2. McNARY LOCK AND DAM, COLUMBIA RIVER, OREG.

Location. The site of this project is on the Columbia River, 292 miles above the mouth, near Umatilla, Oreg., and 3 miles above the mouth of the Umatilla River.

Existing Project. This project includes a dam, power plant, navigation lock, and appurtenant facilities for purposes of navigation, power development, and incidental irrigation. The proposed improvement provides principally for the improvement of navigation, creation of pool extending approximately 64 miles upstream to a point about 27 miles above Pasco, Wash. The dam, which will raise the normal water surface approximately 85 feet to elevation 340 mean sea level, will be approximately 7,600 feet long and will consist of an earth dam at the Oregon (south) abutment, a powerhouse, a spillway dam, a navigation lock, and an earth dam at the Washington (north) abutment. Suitable facilities for migrating fish, including fish ladders, will be provided.

The powerhouse installation will comprise 14 units of 70,000 kilowatts each, making a total installed capacity of 980,000 kilowatts.

The spillway dam will be 1,310 feet long and will be located in the north channel of the river. The overflow crest at 291 feet above sea level will be surmounted by 22 spillway gates capable of releasing the design flood of 2,200,000 cubic feet per second. The deck will be at elevation 361 and will provide a service roadway and tracks for the operation of two gantry cranes.

The navigation lock will be a single type and will operate at all flows less than 800,000 cubic feet per second.

The pool created by the spillway dam will provide a navigable channel with depths of 12 feet and over, between McNary Dam and the confluence of the Yakima River, a distance of approximately 43 miles. A controlling depth of 9 feet will be provided on Snake River from its mouth to a point approximately 10.2 miles above.
