[The passage below is reprinted from pages 7 and 8 of the Annual Report of the Chief of Engineers, U.S. Army, 1949]

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. Theron D. Weaver, Corps of Engineers.

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 1949, including the installation of three power units at each dam is as follows:

Dam 1 Ice Harbor, river mile 9.7 $89,458,000
Dam 2 Lower Monumental, river mile 44.7 81,1222,000
Dam 3 Little Goose, river mile 72.2 91,387,000
Dam 4 Lower Granite, river mile 113.1 79,506,000
Total 341,473,000

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. New Work: The design of Ice Harbor Dam progressed to 23 percent of completion. Hydraulic model construction and tests were completed on the first step cofferdam. Design and field investigations were continued. Continuation of studies and design of fish handling facilities, hydraulic criteria and concrete aggregate investigation are underway. Topographic and hydrographic surveys for Dams No. 1 (Ice Harbor) and No. 2 (Lower Monumental) were complete. A letter report was issued to supplement the Site Selection Report and in lieu of detailed project plans. Detailed project plans on real estate, flowage, and relocations covering the four dams was completed and submitted to higher authority.

Maintenance: No maintenance work was accomplished during the fiscal year 1949.

Total costs $381,865.73 for the fiscal year (all new work) were as follows:

Site selection, lands, and damages (all dam sites) $50,390.49
Ice Harbor Dam (dam 1) 326,745.11

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:

10. Mill Creek, Wash.

Location. Near Walla Walla, Wash., on Mill Creek, a tributary of the Walla Walla River.

Existing Project. The plan of improvement provides for construction of flood-control works consisting of a storage dam, outlet works, diversion works, division structures and improvement of a stretch of Mill Creek Channel, including the reconstruction of the Otis and Merriam Street Bridges across Mill Creek in the city of Walla Walla, Wash.

The storage dam, which will form a reservoir of 6,000 acre-feet capacity, is a rolled earth fill structure 145 feet high, 3,200 feet long at the crest, and 800 feet wide at the base. Flood water is diverted storage by means of diversion work on Mill Creek consisting of a rolled earth fill dam 1,700 feet long and 20 feet high, with a concrete spillway section and headworks at the left abutment, and a concrete-lined canal leading from the headworks to the storage reservoir. Stored water is subsequently released through outlet works consisting of a steel-lined concrete conduit through the base of the storage dam and a canal 5,900 feet in length from the dam to Mill creek. The normal flow of water past the diversion works is apportioned, by means of two concrete division structures, to the three delta streams, Yellowhawk, Garrison, and Mill Creek. The project will control the entire Mill Creek drainage area of 85 square miles and care for a flood of 11,400 second-feet. The existing project was authorized by the Flood Control Act approved June 28, 1938. The Flood Control Act approved August 18, 1941, modified the project in accordance with the recommendations of the Chief of Engineers in House Document 719, Seventy-sixth Congress, third session. The estimated cost, revised in 1948, is $2,270,685 for construction and $133,215 for lands and damages, a total of $2,403,900.

Local Cooperation. For the project, except for Mill Creek through the city of Walla Walla, section 2 of the Flood Control Act approved June 28, 1938, applies. For the section of Mill Creek through the city of Walla Walla, Wash., local interests will provide without cost to the United States all lands, easements, and rights-of-way necessary for construction of the project, and hold and save the United States free from claims for damages resulting from improvement. Assurances of compliance with these requirements received from local interests were approved by the Division Engineer, March 2, 1948. Local interests have contributed $80,000 toward the cost of channel improvement through the city of Walla Walla.

Operations and results during fiscal year. New work: Paving of Mill Creek Channel through the city of Walla Walla was completed.

Maintenance: Ordinary maintenance and repairs were continued. Reservoir regulation was routine. Discharge over the spillway was normal during the whole year. Because of the construction work in Mill Creek Channel in Walla Walla, it was necessary to divert water to the storage dam on the 24th of November. Maximum flow through the intake canal to storage was 160 second-feet. Discharge of storage water was normal through Russell Creek Channel. The second storage period of water occurred on December 12 at which time the maximum intake canal flow was 200 second feet. Discharge from the storage pool was again handled as above. During the balance of the fiscal year there was no necessity for storing water. Peak discharge over the diversion dike spillway was approximately 1,700 second-feet.

Improvements and reconstruction consisting of preparation of plans and specifications for remedial measures to alleviate excessive detrimental seepage from the reservoir was brought to approximately 90 percent of completion. Field surveys and auger borings were completed. Plans and specifications for the compaction of the reservoir, grouting interior drains and new sluice gate were completed. Invitation for bids to design, furnish, install and test new sluice gate was issued June 2, 1949.
