THE SNAKE RIVER- AN ALTERNATE WATER SUPPLY The 1961 joint report of the Bureau of Reclamation and the U.S. Corps. of Engineers entitled, "Upper Snake River Basin," presents a summary of the water resources of the Upper Snake River, together with an analysis of a number of potential water development projects in that area. The attached Plate 1 is based upon information in the joint report showing "present" and "future" average flows of the Snake River below Twin Falls from which it is apparent that a future surplus of water exists at all areas below Hagerman, Idaho.1Epson Perfection 4870 Photo, 400 dpi, 8 bit, 1,341,442 byte

THE PACIFIC SOUTHWEST WATER PLAN In August, 1963, the U. S. Department of the Interior published a report entitled, "Pacific Southwest Water Plan," in which it was emphasized that proposed water development projects along the Colorado River will require an additional water supply of approximately 3.4 million acre-feet per year in excess of the supply available to the lower basin states. The Plan proposes to develop 1 million acre-feet of the required additional water through a number of conservation projects which would salvage Colorado River Water presently being lost by seepage and transpiration. The Pacific Southwest Water Plan proposes to provide the additional 2.4 million acre-feet through the exportation of increased quantities of Northern California water to Southern California and Lake Havasu. This water would be conserved at four large reservoirs on the Trinity and Eel Rivers and conveyed an average of approximately 240 miles, through a combination of new facilities and natural channels to the Sacramento-San Joaquin Delta. From the Delta, the water would be conveyed approximately 300 miles into the southerly end of the San Joaquin Valley through the proposed enlargement of both the California Aqueduct -7-Epson Perfection 4870 Photo, 400 dpi, 8 bit, 1,266,035 byte
