<br /> <br />l-II' 4,100 feet at elevation 344. The reservoir would provide 40,000 <br />Q:) <br /><Xl acre-feet of regulatory storage for the conveyance system from <br /><Xl <br /> <br />a total capacity of 175,000 acre-feet. <br /> <br />Tunnels--Eighteen gravity flow, horseshoe-section, concrete- <br /> <br />lined tunnels would be required. AU tunnels would be single-stage <br /> <br />construction, would be 17.5 feet in diameter, and would have a <br /> <br />capacity of 3,240 c.f.s. <br /> <br />Pipelines--Pipelines would be required for about 85 TIliles of <br /> <br />the aqueduct system. AU pipelines WOLlld be double-barreled, <br /> <br />precast concrete, gravity-flow sections. Each barrel would be <br /> <br />15 feet in diameter and have a capacity of 1,620 c.f.s. The <br /> <br />pipelines would b~ construct~d in two equal stages. <br /> <br />Pumping Plants--Ten pumping plants, constructed in three <br /> <br />stages, would be requiredj ranging ih totai dynamic head [rom <br /> <br />about 173 to 728 feet. The total capacity of each plant after <br /> <br />third-stage construction would be 3,240 c.f.s. ~nd would consist <br /> <br />of nine units, including one standby. The total installed electric <br /> <br />capacity of the pumping plants would be 1,430 megawatts. <br /> <br />Power Drops--Three power drops would be constructed in three <br /> <br />stages to a total hydraulic capacity of 3,240 c.f.s. with eight <br /> <br />units. The total installed capacity of the inline powerplants <br /> <br />would be 372 megawatts. <br /> <br />Canals--All open canals would be con~rote lined Ulld wOllld be <br /> <br />constructed in One stage. The canals would !}[lve a cnpacity of <br /> <br />3,240 c.f.s., a base width of 24 feet, and a water deptll of 17.0 feet:. <br /> <br />22 <br />
