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.

Previous projects. For previous projects see Annual Reports, page 1981 for 1962, page 1991 for 1915, page 2246 for 1903, and page 1986 for 1906.

Existing Project. River and Harbor Act of March 2, 1945 (H. Doc. 704, 75th Cong., 2d sess.) authorized construction of such dams as are necessary and open channel improvements for purposes of providing slackwater navigation and irrigation between the mouth of Snake River and Lewiston, Idaho. This authorization modifies the previous authorizations only for that portion of the improvement below Lewiston, Idaho. The Acts of June 13, 1902, and August 30, 1935, as they pertain to the open river improvement from Lewiston, Idaho to Johnson Bar Landing are part of existing project.

Improvements presently included in the authorized project are as follows:

Item Estimated cost
(July 1963 Base)
Lower Granite Lock and Dam, river mile 107.5 $174,000,000
Little Goose Lock and Dam, river mile 72.2 150,000,000
Lower Monumental Lock and Dam, river mile 44.7 176,000,000
Ice Harbor Lock and Dam, river mile 9.7 $124,962,200¹
Open-river improvement, Lewiston to Johnson Bar Landing² 34,613
Total $624,996,813
¹Includes $285,000 for recreation facilities on completed projects.
²No channel dimensions specified, maintenance only.

Local Cooperation. None required.

Terminal facilities. There are six privately owned grain terminal facilities on Snake River. Four of these are on open river and limited in use for waterway shipping due to shallow channel depths. Two of the terminals are on Ice Harbor pool, one of which is under construction. There are two privately owned terminals below Ice Harbor lock and dam. In addition, there are four publicly owned marinas and nine small boat launching ramps, all open to public use. Facilities are adequate until slack water navigation is available and shipping volume increases following completion of dams now under construction above Ice Harbor.

Operations and results during fiscal year. Operations and results during fiscal year on Lower Granite, Little Goose, Lower Monumental, and Ice Harbor locks and dams are given in an individual report on each of those projects. On Snake River, Lewiston, Idaho, to Johnson Bar Landing, navigation channel markers were installed. Total costs for fiscal year were $22,445,593 for new work, and $485,323 for maintenance.

7. JOHN DAY LOCK AND DAM, COLUMBIA RIVER, WASH. AND OREG.

Location. Site is on Columbia River, about 3 miles downstream from the mouth of John Day River and about 215 miles above the mouth of Columbia River.

Existing Project. As modified consists of a dam, powerplant, navigation lock, fish ladder, and appurtenant facilities with a slackwater pool of about 75 miles long extending to McNary lock and dam. Included is relocation of railroads, highways, utilities, and communities affected by proposed reservoir. Project provides 500,000 acre-feet of flood control storage between minimum pool elevation of 257 and a maximum elevation of 268. Powerhouse provides for 20 generating units of 135,000 kilowatts each. Initial installation consists of 10 units for a total of 1,350,000 kilowatts. Estimated cost of new work, revised in 1963, is $423 million. A detailed description of project as authorized and modified appears on pages 1992 and 1993 of Annual Report for 1962.

Operations and results during fiscal year. Relocation of highways and railroads in reservoir area progressed. During the year 11 contracts were awarded for grading of 38 miles of railroad and 24 miles of highway, and for construction of a railroad bridge, a highway bridge, and two interchange structures. In addition, one 7-mile section of previously subgraded highway was paved. Preparation of plans and specifications for relocations of railroads and highways continued.

For relocation of city of Arlington, initial fill and flood channel in area were completed. Modifications and additions to water and sewer systems in Arlington were essentially complete. Construction of relocated city hall was initiated. Preparation of plans and specifications for relocation of communities continued.

At damsite, work on north shore including lock, spillway, and fish ladder was essentially complete. First phase of second-step cofferdam was completed. Plans and specifications for construction of powerhouse, south shore fish ladder, remaining sections of nonoverflow dam, raising low spillway bays, raising upstream sill in lock, and such other work as necessary to complete dam structure were advertised. Preparation of plans and specifications for electric power generators and associated electrical facilities continued.

Total costs for fiscal year were $40,323,785, all for new work.

Condition at end of fiscal year. At end of fiscal year 44 miles of railroad grading and bridge work out of 140 miles to be relocated had been placed under contract. Overall railroad work is about 5 percent complete. Thirty-nine miles of highway were placed under contract to date, of which 7.5 miles were surfaced and ready for traffic, 3 miles are ready for surfacing. Overall highway relocation work is approximately 20 percent complete. Initial fill for city of Arlington has been completed and area is being turned over to city for development. Replacement building for city hall, fire station, and library is about 70 percent complete. Work on Arlington sewer and water systems being accomplished under contract to the city is 75 percent complete. Contract for construction of navigation lock, north shore fish ladder, dam spillway and embankment is 99 percent complete.

Construction of the project started in June 1958, and the entire project is 27 percent complete. Total costs were $114,042,224, all for new work.

8. COLUMBIA RIVER AND TRIBUTARIES ABOVE CELILO FALLS TO KENNEWICK, WASH.

Location. Project includes improvement of 128 miles of the Columbia River between the head of Celilo Falls and Kennewick, Wash. (See U.S. Geological Survey Map of Washington.)

Previous Project. Original project was adopted by the River and Harbor Act of June 10, 1872, and modified by River and Harbor Act of March 2, 1907. For further details, see page 1992 of Annual Report for 1915; page 1889, Annual Report for 1931; and page 1845, Annual Report for 1938.

Existing Project. Provides for a channel 7 feet deep and 150 feet wide at low water from Celilo Falls to Wallula, with no specified depth or width between Wallula and mouth of Snake River and for an approach channel 6 feet deep at low water from the navigation channel in Columbia River to site of port development at Arlington, Oreg.

Actual cost for new work exclusive of amounts expended on previous project was $1,356,584. Average annual maintenance cost for past 5 years was $13,112.

Incomplete channel rectification work at Owyhee Rapids, Squally Hook, and Indian Rapids, is classified as inactive and excluded from foregoing cost estimate. Cost of this portion, revised in 1954, is estimated to be $419,000.

Construction of The Dalles Dam and raising reservoir has provided a slackwater pool extending upriver to site of John Day Dam and provided slackwater over lower 25 miles of original project. Creation of pool behind McNary Dam (river mile 292) provided slackwater over upper 36 miles of original project. Remaining reach of river included in this project is comprised of approximately 67 miles of open river between The Dalles Pool and McNary Dam. Upon creation of pool behind John Day Dam, slackwater will also be provided over this reach of river, and project will be obviated.

The existing project was authorized by the following:

1Contains latest published map.
2Construction of McNary Dam has obviated the necessity for this work.

Local cooperation. River and Harbor Act approved March 2, 1945, provides that for Arlington Channel, local interests give assurances that they will construct a suitable freight terminal, open to all on equal terms. These assurances were approved December 29, 1947, but a freight terminal will not be constructed because backwater of John Day Dam will inundate present terminal area.

Terminal facilities. On Columbia River from Celilo to McNary lock and dam there are five privately owned grain and oil terminals with connections to truck and rail. Facilities are adequate for existing commerce. Above McNary lock and dam are five publicly owned terminals which handle general cargo and are open for public use. These terminals are adequate for existing commerce, and general development is keeping pace with increasing demands. In addition, there are 15 privately owned terminals serving grain, petroleum, and chemical industries. Also there are five commercial marinas.

Operations and results during fiscal year. On Columbia River, soundings of navigation channel from McNary Dam to John Day Damsite indicated need for dredging at five locations. This dredging was accomplished at all five locations. Total maintenance cost including condition surveys was $29,471.

Condition at end of fiscal year. Authorized 7-foot channel, 150 feet wide has been completed to McNary lock and dam. Controlling depth of 7 feet between the head of The Dalles Pool and McNary Dam was restored by dredging in fiscal year 1962. For that portion of project within McNary pool and The Dalles pool, depths are in excess of 7 feet with minimum depth of 15 feet over upper lock sills. Arlington approach channel was completed in 1948. Total costs were $1,356,584 for new work (includes $400,000 emergency relief administration funds) and $1,040,234 for maintenance.

14. PORTNEUF RIVER AND MARSH CREEK, COLUMBIA RIVER BASIN, IDAHO

Location. Project is at three areas along Portneuf River and along entire length of its main tributary, Marsh Creek, all in southeastern Idaho.

Existing Project. Plan of improvement provides for channel straightening and improvement, removal of obstructions, and construction of new levees and revetments or improvements to existing levees in Blackrock area, in and adjacent to city of Pocatello and in vicinity of Inkom, all on Portneuf River. Plan also provides for channel improvement along lower 39 miles of Marsh Creek.

Existing project was authorized under Columbia River Basin plan by Flood Control Act of May 17, 1950, subject to economic justification. Justification for Pocatello unit was established in fiscal year 1953. After plans and specifications were 88 percent complete, Pocatello unit was classified inactive in 1961 due to failure of local interests to meet sponsorship requirements. After heavy floods in 1962 and 1963, interest in this unit revived, and city and county officials requested that it be reclassified from inactive category. Local interests in Inkom-Marsh Creek area have expressed little desire to participate in plan of improvement, and economic justification has not been established. Estimated cost (1960 base) of Pocatello unit is $748,000. Inkom-Marsh Creek portion of project is considered inactive and excluded from foregoing estimate. Cost of this portion, last revised in 1958, was estimated to be $617,000.

Local cooperation. Section 3, Flood Control Act of June 22, 1936, as amended, applies. In March 1963, city of Pocatello passed a $190,500 bond issue to provide funds for local cooperation requirement and requested reactivation of project.

Operations and results during fiscal year. General design memorandum was initiated for Pocatello unit. Total costs for fiscal year were $2,757.

Condition at end of fiscal year. Because 1962 and 1963 flood flows were greater than flow designed for originally in Pocatello unit, planning studies were initiated to consider providing a channel with a greater design flow. General design memorandum is 5 percent complete. No further work is proposed at this time on Inkom-Marsh Creek unit. No construction work has been done. Total costs were $76,033.

Location. Proposed project is on Boise River in intermittent reaches of channel from vicinity of Boise, Idaho, river mile 52, downstream to the Snake River, river mile 0.

Existing Project. Previous emergency flood-control projects have been accomplished at various locations on this portion of the river. Plan of improvement provides for raising existing levees and structures to existing hydraulic design criteria. It also provides for construction of levees in reaches where protection does not presently exist.

Project was conditionally authorized under the Columbia River Basin plan by section 204 of the Flood Control Act, approved May 17, 1950, (Public Law 516, 81st Congress, 2d session), subject to economic justification. Economic justification was established in fiscal year 1962.

That portion of project in Canyon County from river mile 1 to river mile 37 has been placed in an inactive status due to inability of local interests to meet sponsorship requirements.

Estimated cost of the project (1962) is $504,000. Inactive Canyon County portion of the project is excluded from foregoing cost estimate. Cost of this inactive portion, last revised in 1962, was estimated to be $652,800.

Local Cooperation. . Section 3,Flood Control Act approved June 22, 1936, as amended, applies. Officials of Ada County have furnished a letter of intent to sponsor portion of project in Ada County. Canyon County officials have given written notice that they are unable to meet sponsorship requirements for their portion of the project.

Operations and results during fiscal year. A negotiated contract was awarded to an architectural engineering firm for preparation of general design memorandum for that portion of project in Ada County, and engineering services proceeded. Total costs for fiscal year were $29,380, all for new work.

Condition at end of fiscal year. General design memorandum is complete and has been submitted to higher authority for approval. Canyon County portion of project is in an inactive status. No construction has been done. Total costs were $48,185, all for new work.

17. BRUCES EDDY RESERVOIR, NORTH FORK CLEARWATER RIVER, IDAHO

Location. Bruces Eddy Dam site is on North Fork of Clearwater River 1.9 miles above its junction with Clearwater River, near Orofino, Idaho, and about 35 miles east of Lewiston, Idaho.

Existing Project. Project as authorized to provide a straight concrete gravity dam 630 feet in effective height at normal pool elevation 1,600 and about 3,200 feet long at crest. Dam will create a reservoir having a gross storage capacity of 3,453,000 acre-feet of which 2 million acre-feet would be effective for both local and regional flood control, and for at-site and downstream power generation. In addition, reservoir pool, extending 53 miles into a rugged and relatively inaccessible timberland, will provide important transportation savings in connection with movements of marketable logs and will also afford substantial recreational benefits.

Powerhouse will provide three 100,000-kilowatt generating units to be installed initially, with provisions for three additional 100,000-kilowatt units for an ultimate installed capacity of 600,000 kilowatts.

No significant runs of salmon occur in Clearwater River; however, considerable migrations of steelhead trout are recorded at Washington Water Power Company Dam at Lewiston, Idaho, near mouth of Clearwater River. Accordingly, fish passage facilities will be provided at Bruces Eddy Dam to accommodate present fish movements and improve existing runs.

Bruces Eddy Reservoir site is also the habitat for elk, deer, and other wildlife. Project plans propose acquisition of land outside reservoir limits to mitigate losses of browse areas inundated by reservoir.

Estimated cost for new work, last revised in 1963, is $211 million for a concrete gravity dam with normal pool elevation 1,600. Planning was authorized by Flood Control Act of July 3, 1958 in accordance with plan presented in Senate Document 51, 84th Congress, 1st Session.
