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.


The Walla Walla district, with headquarters at Walla Walla, Wash., was established November 1, 1948, by General Order No. 9, Office, Chief of Engineers, dated September 10, 1948. 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. Wm. Whipple, Corps of Engineers.

Division engineer of the North Pacific Division, Portland, Oreg., comprising the Portland, Oreg., Seattle, Wash., Walla Walla, Wash., and Alaska districts: Col. Orville E. Walsh, 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 $95,899,000
Dam 2 Lower Monumental, river mile 44.7 86,962,000
Dam 3 Little Goose, river mile 72.2 97,967,000
Dam 4 Lower Granite, river mile 113.1 81,977,000
Total 362,805,000

The estimated annual cost of operation and care of the four locks and dams revised in 1947 is $1,940,000.

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

Local Cooperation. No conditions were imposed by law.

Terminal facilities. 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. No work: Due to lack of funds, work during the year was limited to a small amount of aggregate investigation and completion of a preliminary report on powerhouse design by the architect engineer.

Maintenance: Construction of a wire-bound rock jetty, 250 feet long, at Temperance Creek Rapids between Lewiston and Johnsons Bar, was accomplished by hired labor.

Total costs for the fiscal year amounting to $114,393.35 were as follows:

2. McNARY LKOCK 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.

All structures will be founded on a massive basalt flow that reaches a maximum thickness of 130 feet and directly overlies a sedimentary interbed. The principal data concerning the navigation lock and spillway dam are shown in the following table:

The estimated cost of the dam, navigation lock, 14-power unit generating installation, fishways, and attendant buildings and grounds, revised in 1950, is $270,000,000.

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

Operations and results during fiscal year. Washington shore contract was nearly completed during the fiscal year, involving construction of navigation lock with guidewalls, 13½ bays of spillway with apron and baffles, nonoverflow-dam section, partial construction of right-abutment fill and Washington shore fishladder. First step cofferdam was removed in April 1950.

Oregon shore contract was awarded in August 1949. During the fiscal year, the Oregon shore cofferdam was completed, rock excavation for assembly bay and two power units was completed, and contractor's plant for concrete was completed and ready for production.

Preliminary work was done for second step cofferdam to the extent of placing eight rockfilled cribs in the Washington Channel, a 75-foot square rockfilled crib on Artesian Island for cableway foundation, four cells in Oregon Channel, cable way tower was erected on Oregon shore, and left-abutment fill was brought up to elevation 310.

Contracts were awarded for spillway cranes, powerhouse cranes, bascule bridge across lock, turbines Nos. 5 to 8, generators Nos. 5 to 8, lock-miter gates and for miscellaneous equipment.

Work was initiated on two contracts for construction of a 17.8 mile section and a 11.6 mile section of the Spokane, Portland & Seattle Railway including roadway grading on the Washington shore of McNary Reservoir. Approximately 2,761,000 cubic yards of material were excavated and 2,017,000 cubic yards of embankment were placed. Construction was initiated by contract for the relocation of a 11.4 mile section of the Union Pacific Railroad and a 11.1 mile section of U.S. Highways Nos. 730 and 395. Approximately 1,546,000 cubic yards of material were excavated and 1,169,000 cubic yards of embankment placed.

Contract for Richland levees was awarded and completed during the fiscal year.

Contracts were awarded in June for construction of Richland pumping plants and for construction of railroad and highway bridges at Juniper Canyon and Spring Gulch.

Contract plans and specifications for the completion contract of McNary Lock and Dam are well advanced, with submittal to higher authority scheduled for November 1950, advertising for bids in February 1951, and award of contract on May 1, 1951.

Total costs for fiscal year were $36,791,572.86, for all new work. Expenditures were $36,142,060.90.

3. UMATILLA HARBOR, OREGON

Location. This harbor is located on the Columbia River at Umatilla Oreg., 289 miles above the mouth of the same river and 3 miles downstream from McNary Dam.

Existing Project. This provides for clearing the harbor area of all shoals to a depth of 7½ feet below low water from the channel to a line which generally follows the present 7-foot depth contour. This line would extend downstream channelward across the shoal area above the mouth of the Umatilla River.

The existing project was authorized by the Rivers and Harbors Act approved May 17, 1950 (Public Law 516, 81st Cong., 2d sess.).

The estimated cost revised in 1950 is $479,000 for construction. The estimated annual cost of maintenance and operation revised in 1950 is $1,100.

Local Cooperation. The River and Harbor Act approved March 2, 1945, provides that local interests furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas for initial work and for subsequent maintenance as required, and hold and save the United States free from damages due to the construction works and subsequent maintenance. Local interests will repair existing terminal facilities and construct new dock and terminal facilities costing $235,000. Local interests are required to furnish assurances satisfactory to the Secretary of the Army that adequate terminal facilities open to all on equal and equitable terms would be provided.

Terminal facilities. There are no wharves, but there is a terminal where barges are moored close in without the benefit of a shore structure for unloading. There are three tank farms for storage of petroleum products and a cooperative grain elevator adjacent to the harbor.

The port of Umatilla has proposed construction of a dock and terminal facilities.

Operations and results during fiscal year. None. There were no costs or expenditures during the fiscal year.

Condition at end of fiscal year. No work has been done on this project. There have been no cost or expenditures.

Proposed operations. No work is scheduled for fiscal years 1951 and 1952.

4. EXAMINATIONS, SURVEYS, AND CONTINGENCIES (GENERAL)

The total cost of work during the fiscal year was $26,114.92. Expenditures were $25,368.10. The funds unexpended June 30, 1950, amounting to $3,501.36, plus an anticipated allotment of $20,000, will be applied to accounts payable and to contingencies features of work under this heading during fiscal year 1951.

The additional sum of $30,000 can be profitably expended during fiscal year 1952 for contingencies.
