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. Prior to the Act of June 13, 1902, the improvement of Snake River below Lewiston, Idaho, (River Mile 140), was associated with improvement of Columbia River above Celilo Falls. The total cost and expenditure prior to adoption of a formal project was $168,500, of which $153,410 was for new work and $15,090 was for maintenance. For further details see page 1991 of Annual Report for 1915.

Open-river improvement of Snake River from Riparia, Wash. (River Mile 67) to Pittsburgh Landing (River Mile 218) was authorized by Act of June 13, 1902 (H. Doc. 126, 56th Cong., 2d sess.), with no specified channel dimensions above Lewiston. For further details, see page 2246 of Annual Report for 1903 and page 1986 of Annual Report for 1906. This authorization was extended to include improvement from the mouth to Riparia by Act of June 25, 1910 (H. Doc. 411, 55th Cong., 2d sess.), and was further extended to include the reach from Pittsburgh Landing (River Mile 218) to Johnson Bar Landing (River Mile 231) by Act of August 30, 1955. (Rivers and Harbors Committee Doc. 25, 75th Cong., 1st sess.). Under these authorizations the total cost and expenditure for improvement below Lewiston, Idaho was $418,220, of which $246,740 was for new work and $171,480 was for maintenance. In addition, the State of Washington contributed $85,000 in 1907 for new work below Riparia, Wash. The total costs of previous projects are summarized, as follows:

Project New Work Maintenance Total
Prior to June 13, 1902 $153,410.26 $15,089.74 $168,500.00
1902 to Act of March 2, 1945 246,739.54¹ 171,480.34 418,219.88¹
Totals 400,149.80 186,570.08 586,719.88
1In addition, $85,000 for new work expended from contributed funds.

Existing Project. The 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 the existing project.

Improvements presently included in the authorized project are as follows:

Item Estimated cost
(July 1961 Base)
Lower Granite Lock and Dam, river mile 107.5 $151,000,000
Little Goose Lock and Dam, river mile 72.2 146,000,000
Lower Monumental Lock and Dam, river mile 44.7 162,000,000
Ice Harbor Lock and Dam, river mile 9.7 $123,000,000
Open-river improvement, Lewiston to Johnson Bar Landing¹ 34,613
Total $582,734,613
No channel dimensions specified, maintenance only.

Local Cooperation. No conditions were imposed by law.

Terminal facilities. There is a privately owned 40 by 60-foot wharf just above Lewiston at river mile 140.5 which handles passengers and general cargo. There are also two small boat marinas in the Lewiston-Clarkston area in the same vicinity. One new waterside grain terminal of 160,000-bushel capacity has been constructed on Ice Harbor Pool at river mile 29 with initial shipping of grain scheduled for July 1962. There are some nine grain storage facilities above Ice Harbor Pool to Lewiston which are on existing rail lines closely paralleling the river at near water level. Above Lewiston and near Asotin are two grain elevators affording truck-receiving and water-shipping connections.

Ice Harbor pool was raised in December 1961 through January 1962; Lower Monumental Pool is scheduled for raising in December 1967; and slack-water transportation all the way to Lewiston-Asotin area will be available in 1970 if presently proposed schedules for Little Goose and Lower Granite locks and dams are followed. In anticipation of this development all riverside counties have formed port districts and are making plans for future terminal facilities.

Operations and results during fiscal year. Operations and results during fiscal year on Lower Granite lock and dam, Little goose lock and dam, Lower Monumental Lock and Dam, and Ice Harbor lock and dam are given in an individual report for each of those projects.

Total costs during the fiscal year were $18,126,906 for new work, and $148,877 for maintenance.

2. LOWER GRANITE LOCK AND DAM, SNAKE RIVER, WASH.

Location. The project site is located at river mile 107.5 on the Snake River at the head of the proposed Little Goose Pool, and about 33 miles downstream from Lewiston, Idaho.

Existing project. The project provides for a dam, powerplant, navigation lock, and appurtenant facilities, and will require backwater levees near the head of the pool in the Lewiston, Idaho-Clarkston, Wash. area. The improvement will provide for navigation, hydroelectric power generation, recreation and incidental irrigation. The presently proposed normal pool elevation of 735 feet mean sea level, which is subject to review, would create a reservoir extending upstream about 36 miles and would provide slack-water navigation in the Lewiston-Clarkston area. The total length of the dam structure will be approximately 3,100 feet. It will consist of a powerhouse, spillway dam, navigation lock, necessary nonoverflow sections, and fish-passing facilities. The powerplant will be constructed for three 135,000 kilowatt units to be installed initially with provisions for three additional similar units. The spillway will provide capacity to pass a design flood of 850,000 cubic feet per second. The navigation lock will be of single-lift type and will have clear plan dimensions of 86 by 675 feet and will provide a minimum depth of 15 feet over the lock sills. Backwater levees in the Lewiston-Clarkston area will be about 7 miles in length.

The estimate of cost for new work, revised in 1962, is $151 million. The existing project was authorized by the River and Harbor Act approved March 2, 1945. (See H. Doc. 704, 75th Congress, 3d session.)

Operations and results during fiscal year. Hydrologic studies pertinent to planning of the project and studies leading to the establishment of the Lower Granite upper pool level, to be published as design memorandum 1, hydrology, and design memorandum 2, upper pool determination, respectively, have been initiated. Field data for general-design memorandum studies are being accumulated. The dam was sited in the vicinity of mile 107.5 in connection with approved Little Goose Pool studies published in Little Goose design memorandum 1 dated February 13, 1961.

Total costs during the fiscal year were $370,146, all for new work.

4. LOWER MONUMENTAL LOCK AND DAM, SNAKE RIVER, WASH.

Location. The site of this project, in accordance with a letter report dated 20 October 1948, and revised 26 April 1949, was tentatively established at river mile 44.7 above the mouth of the Snake River at the head of Ice Harbor lock and dam pool approximately 45 miles east of Pasco, Wash. The general design memorandum was submitted to higher authority in October, 1959. Detailed planning studies conducted in its development, establish the location of the project at river mile 41.6.

Existing project. The project provides for construction of a dam, power plant, navigation lock, relocation of railroads and highways above the proposed pool level at elevation 540 mean sea level, and appurtenant facilities, creating a slackwater pool about 30 miles long extending to the site of Little Goose lock and dam. The dam, which raises the normal water surface approximately 100 feet above the downstream Ice Harbor lock and dam pool level, will be approximately 3,800 feet long. It will consist of an earthfill and rockfill dam at the right (north) abutment, a powerhouse, spillway dam, navigation lock and an earthfill and rockfill dam at the left (south) abutment. The powerhouse will be composed of three 135,000 kilowatt units to be installed initially and a substructure for three additional units—an ultimate total of six 135,000 kilowatt units or 810,000 kilowatts. The spillway dam will be 508 feet long, and the overflow crest at elevation 483 mean sea level will be surmounted by 8 radial gates each 50 feet wide and 59 feet high. This will provide capacity to pass a spillway design flood of 850,000 cubic feet per second. The deck will be at elevation 553 mean sea level and will provide a service road and track for a gantry crane. The navigation lock is a single-lift type, and will have a clear plan dimension of the lock chamber 86 by 675 feet, and will provide a minimum depth of 15 feet over the lock sills. Fish passing facilities including two ladders will be provided.

The estimate of cost for new work, revised in 1962, is $162 million. 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. Construction work was initiated during the fiscal year on the south shore construction contract. This work includes 7½ bays of the spillway, south non-overflow dam, navigation lock, south fish ladder and south abutment embankment. Work on this contract has just begun and accomplishment is less than one percent of the total contract.

A supply contract for three 135,000 kilowatt turbines was also let during the fiscal year. This was part of a contract for 15 turbine units, 12 of which are for John Day lock and dam. Work done under this contract is less than one percent complete.

A contract was awarded for construction on the north shore access road which extends from the town of Kahlotus to the damsite, a distance of about 5.6 miles, and was 97 percent complete.

5. ICE HARBOR LOCK AND DAM, SNAKE RIVER, WASH.

Location. The site of this project is on the Snake River, 9.7 miles above the mouth of the river, at the head of the McNary lock and dam pool, and 12 miles east of Pasco, Wash.

Existing project. The project provides for construction of a dam, powerplant, navigation lock, fish ladders, appurtenant facilities, and the relocation of railroads. The improvement will provide for navigation, hydroelectric power generation, and incidental irrigation. The dam is designed for a normal pool at elevation 440 mean sea level. The normal pool will create a reservoir extending upstream about 31.9 miles, providing slack water to the Lower Monumental lock and dam site. The total length of the structure will be approximately 2,790 feet. Beginning at the south, the project consists of a concrete nonoverflow section, a concrete powerhouse, a spillway dam, a concrete nonoverflow section, a navigation lock, and an earth-and-rock-filled embankment at the north abutment. Fish-passing facilities, including two ladders, will be provided. The powerplant will be constructed for three 90,000-kilowatt units to be installed initially with provision for three additional units, an ultimate total of six units. The spillway dam will be 610 feet long and the overflow crest at elevation 391 mean sea level will be surmounted by 10 radial gates 50 feet wide by 52.9 feet high which will provide capacity to pass a spillway design flood of 850,000 cubic feet per second. The deck will be at elevation 453 mean sea level and will provide a service road and track for a gantry crane. The navigation lock is a single-lift type and will have clear plan dimensions of 86 feet by 675 feet. A navigation channel with a width of 250 feet and minimum depth of 15 feet will be provided from the mouth to mile 9.7 on Snake River.

The estimate of cost for new work approved in 1962 is $123,700,000. 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. Contract work for completion of the powerhouse structure and installation of equipment was continued throughout the year. Installation of three 90,000-kilowatt generators, main unit transformers, 480 and 4160 volt power centers, switchgear, and 115-kilovolt transmission equipment was completed. First power was produced from unit 1 on December 18,1961. Power units 3 and 2 were placed in service February 8 and 27, 1962, respectively, and produced 537,258 megawatt-hours which were delivered to the Bonneville Power Administration, the marketing agency. During load rejection tests on January 4, 1962, the linkage mechanism in unit 1 failed. The failure resulted in extensive damage to the turbine. Removal of the generator, and disassembly of the turbine is in progress to determine the extent of apparent and other undisclosed damage and the repair necessary. Present indications are that the unit will not be restored to service before February 1963.

Progress under the north shore construction contract continued throughout the year, resulting in completion of the spillway, north nonoverflow dam sections, north shore fishway, navigation lock, and appurtenances. This work involved placing of 70,000 cubic yards of concrete in addition to completing erection and installation of the navigation lock vertical-lift gate and machinery, lock filling and emptying system valves, piping, electrical system, and other fishway and lock-operating equipment. This contract is substantially complete.

The powerhouse completion contract and the north shore contact were advanced to such a stage of completion that initial raising of the pool to elevation 400 feet mean sea level was started November 28, 1961, as scheduled. The remaining raises were taken in 10-foot increments to elevation 422.5 to provide engineering data on the turbines and allow time for repair of slides and settlement areas on the relocated railroads adjoining the reservoir. This final raise was started January 15, 1962, a elevation 422.5 and the normal pool elevation 440 mean sea level was reached April 27, 1962.

The two prior continuing contracts for navigation approach channel dredging involving 700,000 cubic yards of rock and 2,500,000 cubic yards of common excavation, in addition to a third contract involving 101,000 cubic yards of underwater unclassified excavation, were completed this year to provide a 15-foot minimum depth channel to the project.

The construction contract for embankment protection of 14 miles of the Northern Pacific Railway along Ice Harbor reservoir was completed during the year.

A contract for the construction of six concrete pontoons and anchorages for the 553-foot upstream floating guidewall of the navigation lock was completed during the year.

Miscellaneous contracts were completed for stream-gaging facilities, a wind-wave station, a water well, and reservoir recreation facilities. A contract has been awarded for the log boom and cable anchorages of the reservoir debris-disposal facilities, and bids have been opened for the log conveyor portion of these facilities.

Engineering studies are underway on buildings, grounds, and landscaping development at the site, navigation lock fire-protection equipment, and repairs to the spillway stilling basin.

Total costs during the fiscal year were $8,985,842 for new work and $148,877 for maintenance.

Condition at end of fiscal year. The project was placed on a permanent operating basis on January 1, 1962. Dedication ceremonies were held May 9, 1962, through the efforts and sponsorship of local communities and agencies in the area. The work remaining involves completion of engineering studies on lock fore-protection equipment, buildings, landscaping and grounds development, stilling basin repairs and other minor items in addition to completion of security fencing and debris-disposal contracts. The entire project is considered to be 99 percent complete as of June 30, 1962.

Total costs have been $121,895,220 for new work, and $148,877 for maintenance.

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 provides for a dam, power plant, navigation lock, for power, navigation, and incidental irrigation. The dam which raises the normal water surface approximately 85 feet to elevation 340 mean sea level is approximately 7,300 feet long and consists of an earthfill and rockfill dam at the Oregon (south) abutment, concrete powerhouse, spillway dam, navigation lock, and earthfill and rockfill dam at the Washington (north) abutment. The powerhouse has an installation of 14 main units of 70,000 kilowatts each, totaling 980,000 kilowatts. In addition, there are two station service units rated 3,000 kilowatts each. The main units and station service units may be operated, including starting and stopping, from the powerhouse control room. The spillway dam is 1,310 feet long, and the overflow crest at 291 feet above sea level is surmounted by 22 vertical-lift gates placed between piers which extend to elevation 361 mean sea level where a service roadway permits project traffic to cross the dam. Two 200-ton gantry cranes and three fixed hoists provide the means of adjusting the gates. The fixed hoist and the crane hoists can be remotely operated from the powerhouse control room to control five of the 22 gates. The upper end of the reservoir is retained by 17.8 miles of levees, 21 miles of drainage ditches, and 18 pumping plants to protect parts of Pasco, Kennewick, and Richland from flooding. The navigation lock is a single-lift type, capable of operating at all flows less than 1,300,000 cubic feet per second. Facilities for the upstream migration of fish consist of two fish ladders, a lock, and an elevator. All structures are founded on a massive basalt flow that reaches a maximum thickness of 130 feet and directly overlies a sedimentary interbed. The pool created by the dam provides a navigable channel with a depth of 12 feet or over between the dam and the confluence of the Yakima River, a distance of approximately 48 miles.

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, attendant buildings and grounds, and modifications to two railroad bridges is $294 million (July 1962). The construction of additional recreation facilities for the completed project is estimated to cost $325,000, raising the total project cost to $294,325,000. The average annual maintenance cost during the past 5 years was $1,702,292.

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. Contracts were continued and the following facilities have been added to the project: Seeding and planting, two public restrooms, remote control of station service units, and reservoir telemark facilities. Recreation facilities were improved and enlarged mainly by local interests. Negotiations for the proposed disposal of levee 11B and pumping plant to the Port of Pasco were not consummated.

Ordinary operation and maintenance was carried on by both Government forces and local interests. A total of 1,038,400 persons visited the project during the calendar year 1961. This includes visitors to the dam as well as those to the public recreational sites. During the fiscal year, a total of 4,858,783 megawatt-hours of electrical energy were delivered to the Bonneville Power Administration, the marketing agency. A total of 1,087,279 tons, consisting mainly of grain and petroleum products, passed through the lock.

Total costs during the fiscal year were $20,297, for new work and $1,700,449 for maintenance.

Condition at end of fiscal year. Construction of the existing project was begun May 5, 1947. Initial construction is essentially complete as of June 30, 1961; however the addition of modifications to two railroad bridges over the Columbia and Snake Rivers has decreased the percentage complete to 97. Public Law 546, 82d Congress, authorizes modification of a Union Pacific Railroad bridge across Columbia River, and a Northern Pacific Railway bridge across Snake River in order to eliminate serious navigation hazards which were caused by the formation of McNary Reservoir. Additional legislation regarding bridge clearances on navigable streams is now before Congress. Further negotiations for modification of these bridges have been deferred by the owners pending the outcome of this legislation.

The project was placed on a permanent operation basis on December 1, 1953. The pool was raised to normal operating elevation 340 on December 6, 1953. Except for routine maintenance, all 14 power units were in commercial operation since February 1957.

Total costs have been $286,278,679 for new work and $12,423,421 for maintenance.

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

Location. The site of this project 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. The project was originally authorized by the Flood Control Act approved May 17, 1950, in accordance with the plan presented in House Document 531, 81st Congress, 2d session, to provide for a dam, powerplant, navigation lock and appurtenant facilities, with a slackwater pool about 75 miles long extending to McNary Lock and Dam, and the relocations of railroads, highways, utilities, and communities affected by the proposed reservoir. Under this plan the project would provide 2 million acre-feet of surcharge storage space between normal pool elevation 255 and elevation 292 for control of floods on Columbia River. The powerhouse would provide 13 generating units of 85,000 kilowatts each for a total initial installed capacity of 1,105,000 kilowatts.

Subsequent to project authorization noted above a review of the flood-control features of John Day Dam was authorized by resolution of the Senate Committee on Public Works dated April 22, 1953. This review, dated March 25 and revised December 14, 1955, determined that the originally proposed pool fluctuation between elevations 255 and 292 would unduly handicap present and future developments bordering John Day pool. It recommended adoption of normal pool at about elevation 262 with about 500,000 acre-feet of flood-storage space to be obtained between proposed drawdown level at elevation 252 and maximum controlled pool not to exceed elevation 265. Other features of the project would remain essentially unchanged. The Review Report was approved by the Board of Engineers for Rivers and Harbors on January 19, 1956, and submitted to the Congress August 9, 1956, where it was ordered to be printed as Senate Document 10, 85th Congress, 1st session.

The revised project proposed in the Review Report is economically feasible to a slightly greater degree than the project as originally authorized. In addition, it has the firm support of local interests, whereas the original proposal is strongly opposed. Also, planning funds appropriated in fiscal years 1956 and 1957 were based on continuation of studies using pools and storage recommended in Review Report. In view of this situation and contingent upon indicated approval of the Public Works Committees of Congress, the Review Report plan is considered to represent the presently authorized project.

Funds available for advance engineering for fiscal year 1956 were accordingly used in further development of the review report plan and a site selection report was prepared under date of June 15, 1956. Funds available for advance engineering for fiscal year 1957 were used for general design memorandum studies. In accordance therewith, a normal pool level at elevation 265 now appears to be most economical with flood-control storage space in the amount of 500,000 acre-feet available between elevations 257 and 268. The project would include a single-lift navigation lock 86 feet wide by 675 feet long, in clear dimensions, with a normal lift of 105 feet; spillway, with twenty 50- by 58-foot gates, would be designed to pass a flood of 2,250,000 cubic feet per second at maximum pool elevation 276 above mean sea level; and fish ladders and other facilities as necessary would be provided for passage of migratory fish.

Conclusions from completed power studies indicate an initial installation of not less than 10 units and an ultimate installation of 20 units. The nameplate rating of each unit has been increased from 108,700 kilowatts to 135,000 kilowatts. In accordance with inclusion of the completed power studies, the initial power installation will consist of at least 10 units at 135,000 kilowatts each—a total of 1,350,000 kilowatts.

The estimated cost of new work, revised in 1962 is $410,000,000.

Operations and results during fiscal year. Relocation agreement contracts with the Oregon Highway Commission, the Washington Highway Commission, and the Union Pacific Railroad were consummated. Construction of railroad shooflies and highway detours continued during the year and was completed. Grading continued on the highway relocation contracts under the jurisdiction of the Washington Highway Commission. A contract was awarded for grading a section of the Spokane, Portland & Seattle Railway. The John Day River highway bridge contract was awarded by the Oregon State Highway Department under the agreement contract. Work in the city of Arlington on streets, reservoir, water system, and sewerlines is progressing. In addition, two minor contracts for modification of water and sewer systems have been awarded by the city. A contract by the Corps of Engineers for fill, flood channel, and railroad modifications within Arlington was awarded. Construction on the Arlington Elementary School was completed. Work under construction contracts continued in connection with the lock, spillway, and north shore embankment. A portion of the south shore abutment was completed. A contract was awarded for 10 turbine units.

Preparation of plans and specifications continued for the powerhouse and associated features, and for the relocation of railroads, highways, and communities.

Total costs during the fiscal year were $20,378,953, all for new work.

Condition at end of fiscal year. Railroad shooflies and highway detours on which construction was started the previous year are complete. In addition, a contract for another shoofly and a highway detour during the year have been completed. The first contract work on the water system, sewerlines, reservoir, and streets in Arlington is 40 percent complete and is administered by the city of Arlington. Construction of the Arlington Elementary School is complete. Relocation of Wasco Electric Cooperative, Inc., power facilities is 97 percent complete. Relocation of approximately 12 miles of Washington State Highway 8 under the agreement contract with the Oregon Highway Commission is approximately 90 percent complete. A contract for approximately 8 miles of Spokane, Portland & Seattle Railway relocations is about 11 percent complete. Construction of the highway ridge over the John Day River is approximately 20 percent complete. Work on the Arlington fill, flood channel, and railroad relocations is approximately 7 percent complete.

A contract for a section of the south abutment at the dam is complete. The contract for construction of the navigation lock, spillway, and north embankment is 97 percent complete. Included in this work is the removal of the first-step cofferdam from which the upstream leg has been removed.

All work on the project, except grading operations, has been suspended because of an iron workers' strike which started May 28, 1962. The effect of this delay on the overall project schedule cannot be appraised at this time.

Construction of the project started in June 1958, and the entire project is 18 percent complete. Total costs were $74,068,439, all for new work.

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

Location. This 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. The original project was adopted by the River and Harbor Act of June 10, 1872, and modified by the 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. This 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 the mouth of the Snake River and for an approach channel 6 feet deep at low water from the navigation channel in the Columbia River to the site of port development at Arlington, Oreg.

The actual cost for new work exclusive of amounts expended on the previous project was $1,356,584. The average annual maintenance cost during the past 5 years was $13,649.

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

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

The existing project was authorized by the following:

2Construction of McNary Dam has obviated the necessity for this work.

Local cooperation. The River and Harbor Act approved March 2, 1945, provides that for the 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 suitable freight terminal has not been constructed.

Terminal facilities. There are five privately owned terminals on the Columbia River with rail, water, and truck connections with storage capacity of 4,885,000 bushels of grain; three privately owned terminals with truck and water connections with storage capacity of 1,610,000 bushels of grain. Two terminals on the Columbia River have a capacity of 20,200,000 gallons of petroleum products and 448,500 gallons of liquid fertilizer served by water, truck, and rail pipeline. One privately owned terminal on the Snake River at mile 1.9 with water, rail, and truck connection has a storage capacity of 6 million bushels of grain. Two privately owned terminals on the Snake River with water, rail, truck, and pipeline connections have capacities of 50,079,000 gallons of petroleum products, 5,755 tons of dry fertilizer, 893,646 gallons of liquid fertilizer, 25,112 gallons of acid, 45,000 barrels of asphalt emulsions, and 12,000 barrels of cement.

Operations and results during fiscal year. New work in this reach of the river is being continued and reported in connection with John Day lock and dam project.

Dredging was performed at all rapids from The Dalles Reservoir to McNary Dam except at Miller's Drift. The work was performed at a cost of $26,011, all for maintenance.

Condition at end of fiscal year. The authorized 7-foot channel 150 feet wide has been completed to McNary Lock and Dam. The controlling depth between the head of The Dalles Pool and McNary Dam is 7 feet, based on a survey in August,1959. For that portion of the project within McNary pool and The Dalles pool the depths are in excess of 7 feet with minimum depth of 15 feet over upper lock sills.

The Arlington approach channel was completed in 1948.

Total costs have been $ $1,356,584 for new work and $902,864 for maintenance.

12. JACKSON HOLE, SNAKE RIVER, WYO.

Location. This project is located on both banks of the Snake River in the vicinity of Wilson, Wyo.

Existing Project. The plan of improvement provides for a levee with full riprap protection on the right bank, extending from the J.Y. Ranch, which is 10 miles upstream from the Jackson-Wilson Highway Bridge to a point 3.5 miles below the same bridge—a total length of 13.5 miles. The plan also provides for a levee with full riprap protection along the left bank, extending from the north line of the Lucas Ranch, which is 10 miles upstream from the Jackson-Wilson Highway Bridge to a point 5 miles downstream and extending 1.5 miles immediately upstream from the Jackson-Wilson Highway Bridge to a point 3.5 miles below the bridge for a total length of 10 miles. The existing project was authorized by the Flood Control Act approved May 17, 1950 (Public Law 516, 81st Cong., 2d sess.). The estimated cost revised in 1962 is $2,510,000 for construction. The costs of rights-of-way are to be paid by local interests.

Local cooperation. Section 3 of the Flood Control Act approved June 22, 1936, as amended, applies. Formal assurance of local cooperation by the sponsor was approved June 23, 1961.

Operations and results during fiscal year. Surveys on the 3.5 miles below Jackson-Wilson Highway Bridge were completed. Preparation of plans and specifications for this portion of the project began and continued during the year. Total costs during the fiscal year were $27,872.

Condition at end of fiscal year. Construction of the existing authorized project was initiated in November, 1957. Contracts for construction of levees and relocation of irrigation headgates upstream from Jackson-Wilson Highway Bridge is complete. With respect to the 3.5 miles below Jackson-Wilson Highway Bridge, surveys are complete and plans and specifications for the right and left banks are 75 percent complete.

14. LUCKY PEAK RESERVOIR, BOISE RIVER, IDAHO

Location. On the Boise River in southwestern Idaho approximately 9 miles southeast of the city of Boise, and approximately 12 miles downstream from Arrowrock Reservoir.

Existing Project. The plan of improvement provides for construction of a rolled earth-fill dam approximately 250 feet high and 1,700 feet long at the crest, with a reservoir providing a total storage, at normal pool level, of 306,000 acre-feet. The ungated ogee type spillway with unlined channel is located on the left abutment and is designed to pass 93,000 cubic feet per second at maximum pool. The outlet works located on the left abutment consist of a tunnel controlled by six 5-feet by 10-feet slide gate valves.

The plan contemplates the joint use of storage in Lucky Peak, Arrowrock, and Anderson Ranch Reservoirs. Operations of the dam as a flood-control facility will be by the Department of the Army under the direction of the Secretary of the Army with the understanding that complete or partial joint use of the storage in the three reservoirs may be undertaken at such time as may be agreed upon by the Secretary of the Army, Secretary of the Interior, and local interests concerned with flood control and use of irrigation water. The existing project was authorized by the Flood Control Act approved July 24, 1946. Cost of the completed project was $19,081,250. The construction of additional recreational facilities for the completed project is estimated to cost $344,000, raising the total project estimate to $19,425,250. The average annual maintenance cost during the past 5 years was $79,188.

Local Cooperation. No conditions were imposed by law.

Operations and results during fiscal year. Modification of flip buckets 2, 3, 4, and 5 was completed. The accomplishment of this work reduced the amount of water spray on State Highway 21, thus preventing hazardous icing conditions during freezing weather.

Additional recreational facilities were installed by Government forces at one location. These facilities consisted of a boat-launching ramp, parking area, a road, and a boat-landing dock. Other facilities were improved and expanded by the State of Idaho. Recreational facilities continue to show heavy usage, 447,000 persons having visited the project during calendar year 1961.

Normal operation and maintenance of the project continued throughout the year.

Total costs during the fiscal year were $10,881 for new work and $90,465 for maintenance.

Condition at end of fiscal year. Construction of the existing project was initiated in November 1947 and completed in June 1961. Total costs have been $19,110,963 for new work and $525,304 for maintenance.

15. BOISE VALLEY, COLUMBIA RIVER BASIN, IDAHO

Location. The proposed project is located on the Boise River in intermittent reaches of channel from the 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. The plan of improvement provides for the raising of existing levees and structures to existing hydraulic design criteria. It also provides for construction of levees in reaches where protection does not presently exist.

The 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 the 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.

The estimated cost of the project (1962) is $504,000. The inactive Canyon County portion of the project is excluded from the foregoing cost estimate. The cost of this inactive portion was last revised in 1962, and was estimated to be $667,000.

Local Cooperation. . Section 3 of the Flood Control Act approved June 22, 1936, as amended, applies. The officials of Ada County have furnished a letter of intent to sponsor the portion of the 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. The justification report was fully approved. Preparation of the general design memorandum was started. The Canyon County portion (river mile 1 to river mile 37) was placed in an inactive category.

Total costs for the fiscal year were $3,061.

Condition at end of fiscal year. Preparation of the general-design memorandum is 5 percent complete. Canyon County portion is in an inactive status.

Total costs were $43,805.

16. BRUCES EDDY DAM AND RESERVOIR, NORTH FORK CLEARWATER RIVER, IDAHO

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

Existing Project. The current project authorization is limited to detailed planning. As presently proposed the dam would be a straight concrete gravity structure 630 feet in effective height at normal pool elevation 1,600 and about 3,200 feet in length at the crest. The dam would 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, the reservoir pool, extending 53 miles into a rugged and relatively inaccessible timberland, would provide important transportation savings in connection with movements of marketable logs and would also afford substantial recreational benefits.

The powerhouse would 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 the Washington Water Power Company Dam at Lewiston, Idaho, near the mouth of Clearwater River. Accordingly, it is proposed that 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 browse areas outside the reservoir limits to compensate for those inundated by the reservoir.

The estimated cost for new work, last revised in 1961, is $186 million for a concrete gravity dam with normal pool elevation 1,600.

The existing project has not been authorized for construction; however, detailed planning was authorized by the Flood Control Act approved July 3, 1958 in accordance with general plans presented in Senate Document 51, 84th Congress, 1st Session.

Latest estimate of cost for new work, based on estimates in Design Memorandum No. 2, Type and Height of Dam, submitted July 20, 1960, is $166,000,000 for a concrete gravity dam with normal pool elevation 1600.

Local Cooperation. In the absence of authorizing legislation, conditions of local cooperation have not been established. From all standpoints except log transport, project benefits are of national significance and would not normally require local cooperation. Local cooperation may be required in connection with costs of log-passing facilities at the dam because of the local nature of the benefits to be derived.

Operations and results during fiscal year. Design memorandum 1, hydrology, was submitted July 21, 1960, and as a result thereof decision was reached that a concrete gravity dam should be constructed. Subsequently normal pool elevation 1,600 was approved by indorsement dated September 6, 1961. Design memorandum 3, based on a straight concrete gravity dam with the stipulation that studies of a curved dam would be submitted in a supplement thereto. Work was continued on design memoranda concerning concrete aggregates and dam shape and stress analysis, and was started on design memoranda for initial relocations, access and detour roads; reservoir preliminary master plan; supplement to the general design memorandum; and real estate design memorandum.

Field work included core drilling and tunneling for foundation and aggregate information. Core drilling was started at a possible site about 1,200 feet downstream from the original site but information is not complete enough to determine the merits of this location. Surveys of initial relocations and detour roads were begun.

Office work consisted of stress analysis of arch dams of various shapes at slightly varied locations, designs and estimates of different types and arrangements of ancillary and diversion structures, study of project provisions for fish and wildlife, and studies of log-transport methods and benefits in cooperation with the Forest Service.

Total costs during the fiscal year were $586,199.

Condition at end of fiscal year. The general design memorandum has been submitted. A supplement to the general-design memorandum has been started. Status of completion of other design memoranda is as follows: concrete aggregates, 40 percent; dam shape and stress analysis, 35 percent; real estate, 15 percent; initial relocation, access and detour roads, 5 percent; preliminary design report, powerplant, 10 percent; and reservoir master plan, 10 percent.

Total costs were $2,377,301, all for new work.

19. MILL CREEK, WASH.

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

Existing Project. This project consists of an offstream storage dam, outlet works, diversion works, division structures, and 6 miles of improved channel.

The storage dam, which forms a reservoir of 6,000 acre-feet capacity, is a rolled-earthfill structure 145 feet high, 3,200 feet long at the crest, and 800 feet wide at the base. Floodwater is diverted storage by means of diversion work on Mill Creek consisting of a rolled-earthfill 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, 76th Congress, 3d session. Cost of the completed project was $2,162,155. The cost of recreation facilities for the completed project is estimated to cost $210,000, raising the total project estimate to $2,372,155. The average annual maintenance cost during the past 5 years was $21,516.

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 contributed $80,000 toward the cost of channel improvement through the city of Walla Walla. Operation and maintenance costs to local interests were $48,889 for the calendar year 1961 and have totaled $376,852 to date.

Operations and results during fiscal year. New work: Planning was continued for development and use of recreation facilities. A contract was awarded to construct a water-supply system and sanitary facilities.

Maintenance: Ordinary operations and maintenance by the Government continued. Reservoir regulation was routine except diversion of water for bed sealing. One farm bridge over the auxiliary outlet canal was replaced. During the calendar year 1961, 22,000 persons visited the project.

Total costs for the fiscal year were $7,713 for new work, and $21,854 for maintenance.

Condition at end of fiscal year. Construction of the dam and appurtenant works was completed in 1942. An auxiliary outlet canal from the dam to Russell Creek and construction of additional drainage at the toe of the dam were completed in 1944. Paving of the channel through the City of Walla Walla was completed in 1948. Compaction of reservoir area, installation of seepage relief wells, grouting of interior drains, and installation of new sluice gate were completed in 1949 and 1950. The gaging station was relocated in 1957. Stabilizers in that portion of the project maintained by local interests were repaired in 1951, 1952, 1954, and 1955. Most of the stabilizers throughout the entire project have been capped with concrete. Diversion of water for bed sealing operations initiated in 1952 is being continued as conditions permit.
