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

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

Previous Project. 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. 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 as 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 construct a suitable freight terminal, open to all on equal terms. 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 in August 1965. No dredging was required.

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 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. Costs of existing project were $1,356,584 for new work and $990,976 for maintenance, a total of $2,347,560 regular funds.

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 $21,918.

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. 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. Main dam structure includes a spillway in right abutment and an outlet tunnel in left abutment. 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 by raising concrete core wall of main dam 6 feet, reshaping earth and rock dam around core, modifying spillway and outlet works, and raising China Hat Dam 8 feet. New earthfill dikes also would be required across two other southern arms of reservoir to control seepage. By removal of these minor arms from reservoir area, it is anticipated that seepage problems experienced when operating between elevations 6120 and 6124 would not be aggravated and could be mitigated to some extent. These modifications would permit operation of reservoir for flood control to a maximum water surface elevation of 6126, and remove difficulties of irrigation storage use to 6124. Spillway capacity would be increased to 7,000 cubic feet per second by lowering crest elevation from 6118.5 to 6113 and installing new gates. Outlet works to b modernized and rehabilitated, with a capacity of 2,700 cubic feet per second, to work more adequately for flood control operation. 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 1966) is $978,000.

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 progressed. Preparation of general design memorandum No. 2 was started.

Condition at end of fiscal year. Modification of 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, 1965, which requested a review of House Document 531, 81st Congress, 2d 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 1, hydrology, is about 93 percent complete. Foundation exploration drilling at China Hat Dam and at Blackfoot Dam is complete. General design memorandum 2 is about 86 percent complete. 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 1966) is $714,000 Federal and $18,400 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 furnished a letter of intent to sponsor portion of project in Ada County.

Operations and results during fiscal year. Continued protests by Fish and Wildlife Service and by Idaho State Department of Fish and Game against Ada County portion of project delayed start of preparation of plans and specifications. Meetings continued to be held to resolve problems and correct misinformation.

Condition at end of fiscal year. A general design memorandum for Ada County portion of project is approved by higher authority. Efforts continue to make minor revisions in project plans in order to satisfy all local interests. Ada County is acquiring signatures of all landowners in project area to show their intent of furnishing rights-of-way. Before preparation of plans and specifications can be started, further action will be necessary in confirmation of borrow areas and in final coordination with fish and wildlife interests. No construction has been done.

12. 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. Estimated cost of project (July 1965) is $2,230,000 Federal and $18,500 non-Federal consisting of rights-of-way furnished by sponsor.

Local cooperation. Fully complied with.

Operations and results during fiscal year. Design floodflows of 15,000 cfs for riprap protection were experienced during spring of 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 is being made 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.

Existing Project. A general design memorandum dated December 15, 1963, shows two areas with required economic justification. Area "1" begins immediately below town of Mount Vernon, river mile 233, and extends upstream for 2 miles. Area "2" begins about one-half mile below city of John Day, river mile 241, and extends upstream 1.5 miles through John Day and upstream .7 mile along Canyon Creek which converges with John Day River in city of John Day. Project was conditionally authorized under Columbia River Basin plan by section 204, Flood Control Act of 1950, subject to economic justification which was established in 1962. Estimated cost (July 1966) is $626,000 Federal and $101,300 non-Federal for rights-of-way, irrigation facilities, utilities and relocations. These amounts include only the two areas found to be economically feasible.

Local cooperation. Section 3, Flood Control Act of June 22, 1936, as amended, applies. After submission of general design memorandum, officials of Grant County and city of John Day furnished statements of inability to meet sponsorship requirements due to unanticipated local financial problems. Five-year limitation on project authorization began April 8, 1964. Following the December 1964 and January 1965 floods, local interests requested project be reclassified to "active" category. Office of Chief of Engineers approved reactivation April 22, 1965.

Operations and results during fiscal year. Preparation of a revised general design memorandum by an architect-engineer firm was initiated and is in progress.

Condition at end of fiscal year. Revision to general design memorandum is about 70 percent complete. No construction has been done.

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

Location. On both banks of Walla Walla River between Joe West and McCoy bridges near Milton-Freewater, Oreg., 8 miles south of Walla Walla, Wash.

Existing Project. Initial plan provided for channel rectification and improvement of about 7 miles of Walla Walla River near Milton-Freewater (formerly towns of Milton and Freewater, Oreg., at time of initial project authorization). Lower 5.8 miles, between McCoy Bridge and Milton-Freewater powerplant were to be protected by levees with necessary revetment and channel improvement designed for a flood of 18,600 cfs. Upper 1.7 miles extending from Milton-Freewater powerplant upstream to Joe West Bridge were to be improved by some channel clearing. Milton-Freewater and other lower-lying areas extending from former town of Milton to McCoy Bridge in Walla Walla River Valley were intended to be protected from floods with discharge two times as great as that of maximum flood of record. Serious deterioration of riprap has occurred during past few years, and high floods of December 1964 and January 1965 peaked at 9,300 cfs inflicting massive damage to levees. Subsequent determinations in meetings with OCE and NPD indicate that existing project is inadequate for a flow of 18,600 cfs. Proposed rehabilitation of project will provide protection from flows of 12,000 cfs. Revised hydrological data indicates these flows to have a frequency occurrence of 170 years. Project was authorized by 1941 Flood Control Act (H. Doc. 719, 76th Cong., 3d sess.). Initial cost of project as placed in operation in fiscal year 1956 is $886,956 Federal funds, $59,600 for lands and damages paid for by local interests, and $6,300 contributed funds. Additional Federal cost for reconstruction under initial project authorization is estimated to be $800,000, plus $700,000 under authority of Public Law 99, 84th Cong., and antecedent legislation, bringing total estimate (July 1966) to $2,386,956 Federal funds, and $65,900 non-Federal funds.

Local cooperation. Fully complied with for project as initially constructed. In addition, for rehabilitation, sponsoring agency has furnished a quarry, partially cleared brush from levees, and furnished assurances of maintenance.

Operations and results during fiscal year. Rehabilitation planning report was completed, and preparation of plans and specifications started.

Condition at end of fiscal year. Project was turned over to sponsor in fiscal year 1956. Planning report is complete. Plans and specifications for reconstruction and rehabilitation of areas damaged by high floods are 80 percent complete.

18. 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 1966) 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 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. Plans and specifications for Pocatello Unit were completed and a construction contract was awarded.

Condition at end of fiscal year. Construction of Pocatello Unit is scheduled to start early in fiscal year 1967. 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.

25. 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 1966) is $245,740,000, consisting of $243 million Corps funds and $2,740,000 for value of public-domain lands.

Local Cooperation. None required.

Operations and results during fiscal year. Specific design memoranda were forwarded to higher authority for main dam ancillary features supplement 1; main dam postcooling facilities; log handling facilities, permanent fish facilities at dam; concrete aggregate and concrete properties investigations; powerplant preliminary design report; damsite visitors viewpoint development and engineering requirements for construction. Contracts for access and detour road and the diversion tunnel were completed. Resident office contract was awarded and completed. Contract for 2d reservoir clearing was advertised. Temporary fish equipment contracts were awarded. Main contract (dam) was advertised.

Condition at end of fiscal year. Work on following specific design memoranda is continuing: Dent Bridge; Steelhead Fish Hatchery; Highway District Road and County Road. Main dam contract bids will be opened and awarded in early fiscal year 1967. Construction started in April 1963 and project is estimated to be 9 percent complete.
