1. 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 Geological Survey Map of Washington.)

Previous Project. For details see page 1992 of Annual Report for 1915; page 1889, Annual Report for 1931; and page 1845, Annual Report for 1938.

Existing Project. 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. Incomplete channel rectification work at Owyhee Rapids, Squally Hook, and Indian Rapids, is classified inactive. Estimated cost (1954) of this portion is $419,000. Construction of The Dalles Dam and raising reservoir 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 of 1945, provides that for Arlington Channel, local interests give construct a suitable freight terminal, open to all on equally. Assurances were approved December 29, 1947, but site will be inundated when pool is raised behind John Day lock and dam. Port of Arlington agreed to provide adequate public terminal facilities after pool is raised.

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, reconnaissance and condition surveys of navigation channel from McNary lock and dam to John Day lock and dam site were conducted during August 1966. Minor dredging was required at Owyhee Rapids.

Condition at end of fiscal year. Authorized 7-foot channel, 150 feet wide has been completed to McNary lock and dam. For that portion of project in 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. Costs of existing project were $1,356,584 for new work and $1,000,802 for maintenance, a total of $2,357,386 regular funds.

3. NAVIGATION WORK UNDER SPECIAL AUTHORIZATION

Navigation activities pursuant to section 107, Public Law 86-645 (preauthorization)

Fiscal year cost of preauthorization studies for Snake River Navigation Channel vicinity of Weiser, Idaho, was $8,290.

4. BLACKFOOT RESERVOIR, BLACKFOOT RIVER, IDAHO

Location. On Blackfoot River in Caribou County, Idaho, about 40 miles southeast of city of Blackfoot. (See Geological Survey quadrangle sheets Paradise Valley, Cranes Flat, Portneuf, and Henry for location and surroundings in immediate vicinity of project).

Existing Project. Blackfoot Dam and Reservoir is owned and operated by Fort Hall Agency of Bureau of Indian Affairs, Department of Interior. Main dam, which is 52 feet high, is a rockfill structure with a concrete core. A low earthfill dike known as China Hat Dam closes an arm of reservoir near its upstream end to minimize storage loss due to seepage in pervious formation of that area. Existing main dam structure includes a spillway in right abutment and an outlet tunnel in left abutment with a capacity of 2,700 cubic feet per second. Reservoir has a usable storage capacity of 413,000 acre-feet at design maximum water surface elevation 6124. However, due to experience with seepage losses from southern end of reservoir, and past demands for water, operating level has been limited to about elevation 6120, or about 340,000 acre-feet storage capacity. Water stored in reservoir is used to irrigate lands in Fort Hall Indian Reservation in vicinity of Blackfoot and south. Recommended modification of project would provide 38,000 acre-feet additional storage capacity for flood control. Modifications would permit operation of reservoir for flood control to a maximum water surface elevation of 6126. The spillway capacity would be increased to 15,800 cubic feet per second by lowering crest elevation from 6118.5 to 6111.7 and increasing spillway width from 52 feet to 93 feet. Spillway would be equipped with new gates. Outlet works would be modernized and rehabilitated, with a capacity of 2,700 cubic feet per second, to work more adequately for flood control operation. China Hat Dam would be raised 8 feet and Idaho State Highway No. 34 would be raised in grade for approximately ½ mile along with grade raising of two existing bridges. Recommended modification was authorized by Flood Control Act of 1962. Construction to be accomplished by the Corps, with continued operation of project by Bureau of Indian Affairs. Estimated Federal cost of proposed modifications (July 1967) is $1,410,000.

Local cooperation. None required.

Operations and results during fiscal year. Preparation of Design Memorandum No. 1, Hydrology, leading to establishment of a standard project flood and maximum probable flood determination was completed and submitted for approval July 1966. The Walla Walla District was directed by Office, Chief of Engineers, to develop the spillway design flood in accordance with Engineer Circular 1110-2-27 in lieu of spillway design flood developed by Bureau of Indian Affairs. Work is proceeding on development of design flood. Completion of General Design Memorandum No. 2 is contingent upon approval of spillway design capacity.

Condition at end of fiscal year. Modification of Blackfoot Dam and Reservoir in interest of increased flood control for Blackfoot River Basin was first presented as a potential project in review report for Upper Snake River Basin dated 1961, which was prepared jointly by Walla Walla District and Regional Office of Bureau of Reclamation in Boise, Idaho. That review report was authorized by a Senate Resolution adopted March 19, 1954, which requested a review of House Document 531, 81st Congress, 2nd session, with particular reference to Upper Snake River Basin above Weiser, Idaho. In referenced review report, modification of Blackfoot Dam and Reservoir was presented as one of the potential projects warranting early consideration for construction. Interim report No. 2 on modification of Blackfoot Dam and Reservoir, dated March 1962, included additional information and analysis of February 1962 floods and confirmed project economic feasibility. It is on this latter report that congressional authorization is based. Design Memorandum No. 1, Hydrology, is approximately 93 percent complete. Foundation exploration drilling at China Hat Dam and at Blackfoot Dam is complete. General Design Memorandum No. 2 is approximately 95 percent complete based on a spillway design capacity of 15,800 cubic feet per second. If the spillway design capacity is increased, the report will require considerable revision to incorporate the new spillway capacity. No construction has been done.

5. BOISE VALLEY, COLUMBIA RIVER BASIN, IDAHO

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 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 Columbia River Basin plan by section 204, Flood Control Act of 1950, subject to economic justification. Economic justification was established in fiscal year 1962. That portion of project in Canyon County from river mile 1 to 37 is in an inactive status due to inability of local interests to meet sponsorship requirements. Estimated cost of Ada County unit (July 1967) is $749,000 Federal and $18,800 non-Federal for rights-of-way and relocation of utilities. Estimated Federal cost of inactive Canyon County unit (July 1962) is $652,800.

Local Cooperation. Section 3, Flood Control Act of June 22, 1936, as amended, applies. The officials of Ada County have furnished a letter of intent to sponsor that portion of project located in Ada County, but have been unable to obtain rights-of-way from all landowners.

Operations and results during fiscal year. Operations were limited to contacts with local interests concerning the project plan and sponsorship requirements.

Condition at end of fiscal year. Preconstruction planning is complete except for plans and specifications which have not been started due to inability of the sponsor to obtain rights-of-way necessary for local cooperation requirements.

10. JACKSON HOLE, SNAKE RIVER, WYO.

Location. On both banks of Snake River in vicinity of Wilson, Wyo.

Existing Project. A levee with full riprap protection on right bank, extending from J.Y. Ranch, which is 10 miles upstream from Jackson-Wilson Highway Bridge to a point 3.5 miles below same bridge—a total length of 13.5 miles. Also provides a levee with full riprap protection along left bank, extending from north line of Lucas Ranch, which is 10 miles upstream from Jackson-Wilson Highway Bridge to a point 5 miles downstream and extending 1.5 miles immediately upstream from Jackson-Wilson Highway Bridge to a point 3.5 miles below bridge for a total length of 10 miles. Existing project was authorized by 1950 Flood Control Act. Federal cost of completed project is $2,232,681 and $18,500 non-Federal cost consisting of rights-of-way furnished by sponsor.

Local cooperation. Fully complied with.

Operations and results during fiscal year. Design flood flows of 15,000 cubic feet per second were experienced during spring of calendar year 1965. Direct lateral flow of the river attacked the levee previously constructed in three isolated locations requiring emergency repairs to preclude an avulsion. Since stream elevations did not completely follow design criteria, a study was completed in fiscal year 1967 to determine the adequacy of present improvements.

Condition at end of fiscal year. Construction was initiated in November 1957 and project essentially completed in May 1964, except for possible corrective work being considered. Additional inspection of flood damage has resulted in request for authority under Public Law 99 to repair potentially dangerous weakened levees.

15. MILTON-FREEWATER, WALLA WALLA RIVER, OREG.

Location. On both banks of Walla Walla River, vicinity of Milton-Freewater, Oreg., from McCoy Bridge at River Mile 49.5 to Joe West Bridge, River Mile 56.5. See U.S. Geological Maps "Milton-Freewater" and "Bowling Hill" Oreg., dated 1964.

Existing Project. Channel rectification and improvement of about 7 miles of Walla Walla River in the vicinity of Milton-Freewater, Oreg., were authorized by the Flood Control Act of 1941. Project consists of revetted levees and channel improvement designed to protect Milton-Freewater and other low-lying areas in Walla Walla River Valley from flood discharges about two times as great as 1931 maximum flood of record. Construction began in 1947 and was completed in 1953 except for the upper 1.7 miles of channel clearing and rectification which is deferred indefinitely as being nonessential for the designed protection. The initial cost of the project was $886,956 from Federal funds; $59,600 for lands and damages paid for by local interests; and $6,300 contributed funds. Serious deterioration of revetments has occurred during the past few years, and record floods of December 1964 and January 1965 inflicted massive damage to the levees. Since the occurrence of these high flows (9,000 cubic feet per second), hydrologic data have been revised, and new design standards have been set for rehabilitation and reconstruction of the original channel works. Studies have established that previous design is inadequate to contain maximum flows. The present design with latest revised riprap criteria will provide protection from flows of 12,000 cubic feet per second. Present hydrological data indicates these flows to have a frequency occurrence of about once in 170 years. Federal cost for reconstruction and rehabilitation of levees authorized by Flood Control Act of 1941 is estimated to be $1,049,000 plus $587,000 under authority of Public Law 99, 84th Congress.

Local cooperation. Fully complied with.

Operations and results during fiscal year. Plans and specifications were completed and a 360-day contract for $1,315,300 was awarded to reconstruct the lower 5.3 miles of levees and to build a drop structure with fish ladder at river mile 51.9.

Condition at end of fiscal year. Reconstruction began in October 1966 and contract is approximately 79 percent complete.

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

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

Existing Project. Original authorization 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. Project was conditionally authorized under Columbia River Basin plan by 1950 Flood Control Act subject to economic justification. Justification for Pocatello unit was established in fiscal year 1953. Plan for Pocatello unit was modified by design memorandum No. 1 submitted July 22, 1964, which provides for a rectangular concrete channel thru city of Pocatello with revetted levee at either end where development is less extensive. Estimated cost of Pocatello unit (July 1967) is $6,800,000 Federal and $481,700 non-Federal for rights-of-way, a new bridge, and relocation of utilities. Inkom-Marsh Creek unit is considered inactive and excluded from foregoing estimate. Estimated cost of this unit (July 1964) is $750,000 Federal and $38,000 non-Federal for lands and damages and relocations.

Local cooperation. Fully complied with.

Operations and results during fiscal year. Construction of Pocatello Unit started early in fiscal year. Contractor discontinued construction operations in February 1967 due to exhaustion of funds. A small work force was remobilized in May and installation of water diversion system started.

Condition at end of fiscal year. Construction of Pocatello Unit started July 1966 and contract is 45 percent complete. Local interests in other areas have expressed little desire to participate in plan of improvement of inactive Inkom-Marsh Creek Unit, and economic justification has not been established.

23. DWORSHAK RESERVOIR, NORTH FORK CLEARWATER RIVER, IDAHO

Location. Damsite 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 is to provide a straight concrete-gravity dam 630 feet in effective height at normal pool elevation 1,600 and 3,300 feet long at crest. Dam will create a reservoir with a gross storage capacity of 3,453,000 acre-feet, of which 2 million acre-feet will 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 two 90,000- and one 220,000-kilowatt generating units initially, with provisions for three additional 220,000-kilowatt units for an ultimate installed capacity of 1,060,000 kilowatts. No significant runs of salmon occur in Clearwater River; however, considerable migrations of steelhead trout are recorded at Washington Water Power Co. dam at Lewiston, Idaho, near mouth of Clearwater River. Fish passage is not feasible so a hatchery will be provided to mitigate fish runs. Dworshak Reservoir site is 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. Planning was authorized by 1958 Flood Control Act in accordance with plan presented in Senate Document 51, 84th Congress, 1st session. Project authorized for construction by Public Law 87-874. Initial appropriation for construction was by Public Works Appropriation Act of 1962. Estimated total cost for new work (July 1967) is $250,740,000, consisting of $248,000,000 Corps funds and $2,740,000 for value of public-domain lands.

Local Cooperation. None required.

Operations and results during fiscal year. Main contract (dam) was awarded ($131,216,855). Specific design memoranda were forwarded to higher authority for Steelhead Fish Hatchery, Dent Bridge, Highway District Roads and County Roads. Contract for Third Reservoir Clearing was advertised. Contract for powerhouse main turbines was advertised.

Condition at end of fiscal year. Work on following specific design memoranda is continuing: Reservoir, Master Plan, Buildings and Grounds at Damsite and Recreation Sites. Steelhead Fish Hatchery contract is scheduled to be advertised in early fiscal year 1968. Construction started in April 1963 and project is estimated to be 17 percent complete.
