The project is an essential unit in the authorized slack-water navigation and hydroelectric power development of lower 360 miles of Columbia River and the lower 140 miles of Snake River. Estimates shown in the Bonneville Power Administration Power Outlook 1960-70 indicate that Pacific Northwest regional resources now existing and under construction, including Ice Harbor, will meet system firm energy demand in the winter season of 1962-63, the first full season of power production for Ice Harbor. Continual development of additional resources will be required to keep pace with prospective power demands in the Pacific Northwest region; and power shortages, if they occur, will retard industrial and other development essential to regional economic growth. The development of navigation on Snake River will extend the Columbia-Snake River authorized waterway. It is estimated that about 2,600,000 tons of commerce would move annually on and through the Ice Harbor pool after all four of the lower Snake River projects are completed. An additional 1,400,000 tons is expected to develop from the Lime Point area after the proposed Asotin project is completed. Commerce on the Ice Harbor pool will be principally bulk commodities such as wheat, wood products, limestone, ores, petroleum and fertilizers. The development of Ice Harbor Lock and Dam as a unit of the slack-water plan on Snake River will provide for early shipping of grain and receiving of petroleum and fertilizer products. The project will extend the waterway influence or tributary shipping area some 60 to 75 miles above the head of the project pool. The project will also reduce pumping lifts for irrigation developments along the reservoir shore line and will provide incidental recreational benefits. 70856 0-61-pt. 1-31 ICE HARBOR LOCK AND DAM, WASHINGTON (Continued) FISCAL YEAR 1962: The amount of $8,200,000 will be applied as follows: Complete acquisition of lands Continue Northern Pacific Railway Embankment Protection Complete reservoir clearing 100,000 70,000 Complete construction of dam, navigation lock, fish facilities, powerhouse and installation of equipment 3,800,000 Complete procurement of turbines, generators, accessory and miscellaneous power plant equipment Complete procurement of permanent operating equipment 80,000 Complete construction of permanent buildings and utilities Supervision and Administration TOTAL The funds requested for Fiscal Year 1962 will complete the project except for deferred construction work. STATUS OF LOCAL COOPERATION: None required. $8,200,000 COMPARISON OF FEDERAL COST ESTIMATE: The current Federal (Corps of Engineers) cost estimate of $121,000,000 is a decrease of $4,000,000 from the latest estimate ($125,000,000) submitted to Congress. Changes which contributed to reductions in the estimate included net decreases of $1,613,000 for more detailed design and investigations, $874,000 due to favorable bids and negotiations for agreements, $3,254,000 for reduction of contingencies, $1,000,000 for exclusion of deferred construction costs estimated to be required for relocations following completion of the project, and $710,000 in Supervision and Administration based on costs to date and estimated future requirements. These reductions were partially offset by increases of $170,000 for higher price levels, $3,121,000 for overruns on existing contracts, and $160,000 for Engineering and Design based on costs to date and a reanalysis of future requirements. |
