The accompanying map shows the reservoir conservation opportunities in the North Coast area, as copied from the State's Preview of Bulletin No. 136, which, it is generally agreed, present the best opportunities of development. Additional intensive investigation is required, however, to firm up the details of the specific individual facilities. The storage facilities tentatively proposed in the Initial Plan Pacific Southwest Water Plan, for demonstration of economic justification and financial feasibility of the entire Initial Plan, consist of Helena Reservoir on the main stem of Trinity River and the Eltapom Reservoir on South Fork Trinity River, with tunnel diversion to Clear Creek, and thence, down that stream through regulatory storage and powerplants to the Sacramento River. It is estimated in the California Department of Water Resources Preview of Bulletin No. 136 that 1,200,000 acre-feet of water yield would be developed from these reservoirs, together with associated diversion and power facilities, at a cost of $540,000,000. In addition, Bureau of Reclamation preliminary estimates indicate a cost of $60,000,000 for transmission of the power generated at these plants to the load center at Tracy for distribution to help supply the pumping power requirements of the plants along the proposed enlarged East Side Canal. Also the Fish and Wildlife Service contemplates facilities estimated to cost $17,000,000. Thus, the total cost of the Trinity Reservoir supply of water is estimated at $617,000,000. 33Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,295,040 byte
