JUSTIFICATION The project will provide protection to an estimated 8,000 acres of irrigated land, irrigation works, a branch line of the Union Pacific Railroad, U.S. and State highways and numerous county and farm roads and bridges. In addition, the project will furnish protection to residential, business and commercial developments that are vulnerable to floods of greater than bank-full capacity. In 1963 flooding caused damages of $256,000, of which $248,000 could have been prevented by the project. Total annual benefits creditable to the project are estimated at $138,200. Non-Federal costs.-The investment required of local interests in construction of the authorized project is estimated at $140,000 broken down as follows: Lands____ Relocations--. Total______ $68, 200 71, 800 140,000 The total annual cost to local interests for maintenance is estimated at $9,200. Status of local cooperation.-The Idaho Flood Control District No. 1 has expressed its willingness to sponsor the flood protection works. Formal assurances will be requested upon completion of detailed planning. Comparison of Federal cost estimates.-The current Federal cost estimate of $1,830,000 is a decrease of $3,820,000 from the latest estimate of $5,650,000 submitted to Congress. The decrease is principally due to change in scope resulting from elimination of areas found to be not economically feasible of construction at this time. SHELTON DITCH, OREGON (Continuation of planning) Location and description.-Shelton ditch, about 2.6 miles long, is located almost entirely within the southern part of the city of Salem, Oreg. It flows westerly from a diversion structure in Mill Creek to the Willamette River. The plan of improvement consists of construction of 2.3 miles of concrete-lined channel.

Expansion of the city has encroached on lands along both the Mill Creek and Shelton Ditch channels. Improvement of the channel of Shelton Ditch will provide greater carrying capacity and reduce erosion and flood overflow damages to residential and industrial areas both along Shelton Ditch and along Mill Creek below the Shelton Ditch diversion. Total annual benefits creditable to the project are estimated at $131,800. Non-Federal costs.-The investment required of local interests in construction of the authorized project is estimated at $152,000 broken down as follows: Lands--- Construction of a bridge and utility modifications___. Total____ $42, 000 110,000 152,000 Status of local cooperation.-Assurances of local cooperation have not been requested. Comparison of Federal cost estimates.-The current estimate of $1,950,000 is an increase of $90,000 over the latest estimate ($1,860,000) submitted to Congress. This increase is attributed to higher price levels and reestimates of project feature costs. SNETTISHAM POWER PROJECT, ALASKA (Continuation of planning) Location and description.—The project site is located near the mouth of the Speel River, 28 miles southeast of Juneau, Alaska. The plan of improvement consists of diverting water from Crater and Long Lakes through separate tunnels and penstocks to a 60,000-kilowatt powerplant at tidewater. The project includes tunnel intakes, gate shafts, trash racks, surge tanks and approximately 39 miles of 115,000-volt transmission line to the Juneau area. This project will be constructed in three stages with 20,000 kilowatts of capacity being installed in each stage. Authorization.-Flood Control Act of 1962. Estimated non-Federal cost-- Reimbursement: Power_ Total estimated project cost (initial). Total estimated project costs for ultimate installation_. 30, 700, 000 30, 700,000 30, 700,000 44, 300, 000 1,700,000 0 225,000 750,000 Balance to complete preconstruction planning after fiscal year 1965-- 725,000 11st stage construction. JUSTIFICATION Power to be produced by the Snettisham project is needed to meet the demands of the growing power market in the Juneau area. The Department of Interior has estimated that there will be a shortage of about 5,300 kilowatts of peaking power in the Juneau area by 1970, about 28,130 kilowatts by 1980, and 56,000 by 1987. Additional demands could be placed upon the project to replace present unreliable and high cost generation. The project will provide 56,000 kilowatts of dependable capacity and generate 288,000 kilowatt-hours of energy having an annual benefit of $3,541,000. Non-Federal costs.-Total project costs are allocable to power and are reimbursable. Status of local cooperation.-None required for construction. Responsibility for repayment of power costs rests with Department of Interior pursuant to Federal laws. Comparison of Federal cost estimate.-The current Federal cost estimate of $30.700,000 (initial development) is an increase of $1,300,000 over the latest estimate ($29,400,000) presented to Congress. This increase is attributed to higher price levels and reestimates of project feature costs. LIBBY DAM, KOOTENAI RIVER, MONT. (Continuation of planning) Location and description.-The project site is located on the Kootenai River about 17 miles upstream from Libby, Mont., and 219 river-miles above the confluence of the Kootenai with the Columbia River. The plan of improvement provides for a concrete gravity dam, with powerhouse, which will create a reservoir 90 miles long, backing water 42 miles into Canada to the tailwater of the Bull River Dam site, 5 miles upstream from Wardner, British Columbia. Authorization.-1950 Flood Control Act. Summarized financial data Estimated total appropriation requirement. $332, 000, 000 -253, 700, 000 78, 300, 000 Future non-Federal reimbursement_.

Flood storage provided by the project will aid in reducing flood damages on the lower Columbia River and on the Kootenai River downstream from the dam. Power will be realized from at-site generation and from controlled release of storage for power generation at downstream hydro plants. The project, in combination with Canadian storage and existing storage in the Columbia Basin, will permit control of the maximum flood of record on the lower Columbia River (1894 flood with peak discharge of 1,240,000 cubic feet per second at The Dalles) to less than 800,000 cubic feet per second at The Dalles. On the Kootenai River downstream from the dam, in combination with the existing levee system, flood storage provided by the project would practically eliminate flood damages along the Kootenai River in the Kootenai Flats area, which extends about 70 miles downstream from above the town of Bonners Ferry, Idaho, to Kootenay Lake. In this area, levee systems protect 34.400 acres of fertile farmland in the United States, including the town of Bonners Ferry, and 17,500 acres in Canada. The area of leveed land flooded in the U.S. portion of Kootenai Flats amounted to 32,000 acres in 1948, 4.800 acres in 1950, 6,600 acres in 1954, 17,000 acres in 1956, and 7,000 acres in 1961. When included in a system consisting of projects now existing and under construction, Canadian storage, and with Kootenai-Columbia diversion as proposed in the treaty with Canada, the project would generate an average of 1,597,500,000 kilowatt-hours annually at site and be credited with about 1,461,500,000 kilowatthours annually at downstream plants. Non-Federal costs.-Costs allocable to power, estimated at $253,700,000, are reimbursable. Status of local cooperation.-None is required. The responsibility for repayment of costs allocated to power rests with the Department of the Interior, pursuant to Federal laws. Comparison of Federal cost estimates.-The current Federal cost estimate of $332 million is the same as last submitted to Congress. LOST CREEK RESERVOIR, OREG. (Continuation of planning) Location and description.—On the upper Rogue River about 26.5 miles northeasterly from Medford, Oreg. The plan of improvement provides for the construction of a rock and gravel embankment including a spillway, outlet tunnel, regulating tower, and a powerhouse. Authorization.-1962 Flood Control Act. Benefit-cost ratio.-1.3 to 1. Estimated total appropriation requirement.... Summarized financial data $79, 900, 000 -43, 011, 000 36, 889, 000 43, 011, 000 Future non-Federal reimbursement__.

Balance to complete preconstruction planning after fiscal year 1965- JUSTIFICATION 34, 570, 000 5,538, 000 2,903, 000 79, 900, 000 1,600,000 0 100, 000 350, 000 1, 150, 000 Lost Creek Reservoir is the principal unit of the comprehensive development of the Rogue River Basin. Lost Creek and Elk Creek Reservoirs are to be operated as an integral unit to realize benefits from all authorized functions. Lost Creek Reservoir is considered to be the key project of the two-unit system. The Lost Creek Reservoir would control about 674 square miles of stream runoff. A total of 315,000 acre-feet of usable storage at this project would be utilized for flood control, fishery enhancement, irrigation, hydroelectric power generation, recreation, and other purposes. Lost Creek and Elk Creek, together, would provide water for irrigation of a total of about 50,000 acres of land, of which 34,000 would be new lands; provide increased flows of adequate quantity and quality for fish enhancement; provide 20,000 acre-feet of stored water for future water supply; and reduce the peaks of floods. During the flood of 1955, one of the most severe floods since 1890, damages to the area downstream of Lost Creek Reservoir amounted to $3,030,000 ($3,800,000 at present price levels) of which about $1,630,000 ($2,030,000 at present price levels) would have been prevented by Lost Creek Reservoir. Annual benefits creditable to Lost Creek Reservoir amount to $4,444,300. Non-Federal costs.-Costs allocable to power, irrigation, and water supply, presently estimated at $34,570,000, $5.538,000, and $2,903,000, respectively, are reimbursable. Status of local cooperation.-Responsibility for repayment of irrigation and power costs rests with the Department of Interior pursuant to Federal laws. The Oregon State Water Resources Board has indicated that there should be no difficulty in obtaining reimbursement of cost allocated to water supply. Comparison of Federal cost estimates.-The current estimate of Federal cost of $79,900,000 is an increase of $2,700,000 over the latest estimate ($77,200,000) submitted to Congress. This increase is due to higher price levels and revised estimates of project feature costs. CONSTRUCTION, GENERAL COLUMBIA AND LOWER WILLAMETTE RIVERS BELOW VANCOUVER, WASH., AND PORTLAND, OREG.
