General LAPSLEY. That is correct, sir. Mr. JENSEN. Would that complete the review? General LAPSLEY. That is to complete the study of the Ben Franklin Dam site to come up with a project which would be, if recommended and approved, in the omnibus bill. Eight-hundred-thousand dollars of the $936,000-which includes $200,000 for this year and $736,000 for the remainder is the Atomic Energy Commission's estimate of what their part will be. Mr. JENSEN. Now, what is the estimated cost of the finished project? General LAPSLEY. About $164 million, sir, but I would qualify that by saying that is taking the lower estimate of the AEC's remedial work. If it goes above that, as developed in the study, it would add to the total estimate. Mr. JENSEN. How much of this $936,000 goes to the Atomic Energy Commission? General LAPSLEY. $800,000, sir. That is their estimate. Mr. JENSEN. So you are making a study and they are making a study? General LAPSLEY. We have made a feasibility study of the dam. They are making a study to determine what saturation, that is, raising the ground water at the Hanford works, would do to the stability of their works, and particularly the complications it might cause in disposing of radioactive waste. Mr. JENSEN. Mr. Chairman, it appears to me there might be some conflicting interests here. I think it would be well for us to remember to ask the Atomic Energy Commission about this item when they appear before the committee. Mr. CANNON. Yes. CONSTRUCTION, GENERAL (ADVANCE ENGINEERING AND DESIGN) BLACKFOOT RESERVOIR, IDAHO Mr. CANNON. We shall turn now to Advance Engineering and Design and take up first the Blackfoot Reservoir, $46,000. Please place in the record page 13 of the justification. (The page follows:) BLACKFOOT RESERVOIR, BLACKFOOT RIVER, IDAHO (Initiation of planning) Location and description.-The project is located on the Blackfoot River about 40 miles southeast of the city of Blackfoot. The plan of improvement would increase the usable storage capacity 37,800 acre-feet, from 413,200 to 451,000, by raising the existing main dam and an auxiliary side channel dam and by modifying spillway and outlet works. This would permit operation of the reservoir for food control in addition to primary irrigation use. Authorization.-1962 Flood Control Act. Benefit-cost ratio.-2.5 to 1. The project modification will provide further flood protection to lands adjacent to the lower Blackfoot River, Idaho, and will permit more flexibility in the operation for flood control and irrigation. The area subject to flooding consists of agricultural, residential, and commercial properties, transportation facilities and utilities. The properties in the flooded area have a value of $2,620,000. Benefits consisting entirely of flood damages prevented by the project, are estimated at $81,700 annually. Non-Federal cost.-None. Status of local cooperation.-No local cooperation required. The Bureau of Indian Affairs has requested that the Corps of Engineers act as the construction agency for all project modifications, including the procurement of any and all additional rights-of-way required for flood control storage. Comparison of Federal cost estimates.-The current estimate of $870,000 reflects an increase of $11,000 over the latest estimate ($859,000) submitted to Congress. This increase is due primarily to price level increases. Mr. CANNON. Please explain the need for and the interest in this new planning start. General LAPSLEY. Sir, this is a plan to provide for raising the height of an existing dam by 6 feet, thereby increasing its storage capacity by 37,800 acre-feet, from 413,200 acre-feet to 451,000 acre-feet, and modifying the spillway and outlet works to provide for flood control as well as irrigation. The existing dam is a Bureau of Indian Affairs dam. The additional benefits will be $81,700 annually, all attributable to flood control. Mr. CANNON. You are in need of this additional capacity? General LAPSLEY. Yes, sir. Mr. CANNON. Who built this dam and when was it built and why was the need for this additional capacity not foreseen at that time? General LAPSLEY. This dam was built, sir, solely for irrigation. There has been development in the area downstream and floods such as could happen in the area would practically wipe out the area down below and cause considerable damage. This is something that has developed since the dam was built as an irrigation dam only. This is not our dam. This is a Bureau of Indian Affairs dam. Mr. CANNON. This could not have been foreseen? General LAPSLEY. Not to my knowledge, sir. Sir, in answer to your question, the original dam was built in 1908 and 1909. Mr. CANNON. There has been quite a lapse of time, then? General LAPSLEY. Yes, sir. WYNOOCHEE RIVER, WASH. Mr. CANNON. The next project is Wynoochee River, Wash., for which you are requesting $200,000. Please place in the record pages 24 and 25 of the justification.) (The pages follow:) WYNOOCHEE RIVER, WASH. (Initiation of planning) Location and description.-The project will be located on Wynoochee River, a tributary of Chehalis River, about 23 miles north of Montesano, Grays Harbor County, Wash. It will be constructed in two stages. The initial stage provides for a dam and reservoir of approximately 68,000 acre-feet of total storage for water supply, flood control, irrigation, fish and wildlife enhancement, and recreation. The second stage would consist of enlarging the initial project to provide increased capacity for power purposes, construction of a powerplant and a downstream reregulating dam. Authorization.-1962 Flood Control Act. Benefit-cost ratio.-1.2 to 1, initial development; and 1.4 to 1, ultimate develop ment. Summarized financial data Estimated total appropriation requirement_ Estimated Federal cost (initial)__ Estimated non-Federal cost (initial). Power_-_ Total estimated project cost (initial). Estimated Federal cost for ultimate stage of development_- Preconstruction planning estimate___ Allocations to June 30, 1963. Allocation for fiscal year 1964. Planning allocation for fiscal year 1965. Balance to complete preconstruction planning after fiscal year 1965 1 Initial stage of development. 2 Approximately $7,100,000 of initial project costs are allocable to power. However, in planning the first phase, construction of a less costly project at an upstream site for all purposes other than power will be investigated, If this is feasible, stage II construction would provide a project for power. JUSTIFICATION The initial project would meet one of the foremost economic needs of the area by furnishing an increased, reliable water supply. The area is economically dependent on the pulp and paper industry and at present the total reliable natural streamflow is being utilized by existing plants. Continued growth of this industry necessary to maintain economic stability is dependent on augmentation of these flows. The first stage of the project would triple the present water supply. In addition, the first stage would provide flood control for 4,000 acres of farmland, irrigation for 3,440 acres, limited recreational facilities, and an improvement in survival of migratory fish through an increase in summer flows. At such time as power needs warrant, construction of the second stage would add 60,000 kilowatts of installed hydroelectric capacity to the Northwest power pool to help meet the increasing peaking power demands. The higher pool would make available desirable recreational sites for water sports and camping on the valley floor on each side of the reservoir. Average annual benefits for initial development are estimated at $695,000 and for ultimate development $1,837,000. Non-Federal cost.-Construction costs allocable to water supply and irrigation, presently estimated at $2,229,000 and $565,000, respectively, are reimbursable. In addition, initial project costs allocable to power, currently estimated at approximately $7,100,000, would be assigned for repayment upon construction of the second stage project with power. Local interests must bear annual costs allocable to water supply and irrigation, presently estimated at $39,000 and $11,000, respectively. Also local interests will expend approximately $2 million for expanded water supply diversion facilities. 82-218-64-pt. 1—5 Status of local cooperation.-The city of Aberdeen has agreed to pay costs allocated to water supply in accordance with the Water Supply Act of 1958 (Public Law 85-500). Responsibility for repayment of irrigation and future power costs rests with the Department of the Interior, pursuant to Federal laws. Comparison of Federal cost estimates.-The estimate reported on the justification sheets is for the initial stage of a two-stage development plan. An estimate for the initial stage has not previously been submitted to Congress. Mr. CANNON. This project seems to be planned as a two-stage development. Please explain it and tell us what the ultimate total cost is likely to be. General LAPSLEY. This plan of improvement contemplates the ultimate construction of a multipurpose concrete dam 295 feet high with a storage capacity of 276,000 acre-feet for flood control, water supply, irrigation, fish and wildlife enhancement, recreation facilities, and power. The initial stage of development would provide an increased industrial water supply and, in addition, would provide flood control for 4,000 acres of farmland, irrigation for 3,440 acres, limited recreational facilities, and an improvement in survival of migratory fish through an increase in summer flows. The benefits for initial development are estimated at $695,000 annually. This dam would be raised and the power facilities added in the ultimate construction. At the present time the power is not needed in the system but the water supply is critically needed in this area, which is in a redevelopment area. Industry is now limited by the lack of sufficient industrial water. This is the initial stage to provide the needs now. Mr. CANNON. Off the record. (Discussion off the record.) OTHER ADVANCE ENGINEERING AND DESIGN PROJECTS Mr. CANNON. The justifications on other Advance Engineering and Design projects will be placed in the record at this point. (The matter referred to follows:) COLUMBIA RIVER AT THE MOUTH, OREGON AND WASHINGTON (48-FOOT CHANNEL) (Continuation of planning) Location and description.-Located at the mouth of the Columbia River, 13 miles westerly of Astoria, Oreg. The plan of improvement provides for a 48-foot channel to be obtained by dredging and construction of a jetty. Authorization.-1954 River and Harbor Act. 143, 000 Balance to complete preconstruction planning after fiscal year 1965– 1 Local interests contributed $500,000 for jetty construction under a previous modifica. tion. 2 Uncompleted portion. JUSTIFICATION The mouth of the Columbia River is the gateway for all foreign and domestic commerce entering or departing from Columbia River. An adequate channel of 48 feet at the mouth of the Columbia River is essential to the economy and industry of a large portion of the northwest region of the United States. Benefits accruing to the 48-foot channel are based on less delay due to storms, less cargo shut out, and fewer groundings. Increased channel depths increase the range of weather conditions through which vessels can navigate the entrance channel with safety. Other benefits include safety and convenience to a large commercial fishing fleet and thousands of recreational boaters. Traffic during calendar year 1962 totaled 12,651,633 tons and has averaged 11,530,000 tons per year during the preceding 10-year period. Tidal hydraulic studies and hydraulic model studies are in progress and are programed to continue through fiscal year 1967. Continuation of these related studies will aid in establishing the type and location of structures to complete the 48-foot channel modification. The initial work of dredging the channel to a depth of 48 feet has been completed. The remainder of the modification involves construction of jetty B or other contraction works in the interest of reducing maintenance dredging and assuring the continuous availability of project dimensions. Benefits for the overall modification, including both dredging and contraction works, are estimated to amount to $1,400,000 annually. COMPLETED MODIFICATIONS The development of the entrance channel was authorized under River and Harbor Act 1884. Under the previous modification, the channel was developed by dredging and construction of stone jetties and contractual works to obtain a channel 40-feet deep. Total cost for construction was $13,843,800 including $500,000 cash contribution by ports of Portland and Astoria. None. REMAINING AUTHORIZED MODIFICATION Non-Federal costs.-The authorizing legislation does not require local cooperation. However, during 1914 the port of Portland contributed $475,000 and the port of Astoria $25,000, the greater part of which was applied to the purchase of stone for the north jetty. Status of local cooperation.-None required. Comparison of Federal cost estimates.-The current Federal cost estimate of $11,300,000 is an increase of $100,000 over the latest estimate ($11,200,000) submitted to Congress. The increase is due to higher price levels. HEISE-ROBERTS EXTENSION, SNAKE RIVER, IDAHO (Continuation of planning) Location and description.-The project extends along the Snake River, downstream from the existing project, from the mouth of Henry's Fork to Roberts Bridge, a distance of 18 miles by the present channel, and along Henry's Fork from its mouth upstream to Texas Slough and along the lower 2 miles of the slough. The project will provide for channel rectification, levees and partial revetment, drainage structures, and a pumping plant. Authorization.-Flood Control Act of 1950. Benefit-cost ratio.-1.6 to 1. |
