<br />The hydraulic design for the canal includes estimated losses and <br />unexpected downtime which allows for approximately a two month shut- <br />down period without significantly affecting the total systems oper- <br />ation. The pumping plants include one standby unit per plant for <br />normal repair and operational procedures. <br /> <br /> <br />WATER TRANSPORT SYSTEM (Canals/Pumping Plants/Siphons) <br /> <br />General. The water transport system consists of canals, pumping <br />plants and crossing facilities for water courses and manmade appur- <br />tenances. This system has the capacity to carry 1,550,000 acre-feet <br />with Plan I, and 8,700,000 acre-feet with Plan II. Both plans utilize <br />primarily open channels with pumping stations to lift the water as <br />necessary and siphons or other techniques to cross rivers, streams, <br />highways or other manmade facilities. The proposed canal is a concrete <br />lined channel to decrease percolation of transport water into the <br />substrata, to increase the hydraulic efficiency and also to reduce the <br />operation and maintenance effort. <br /> <br />The tentatively selected alignment was developed to generally <br />follow major drainage divides, reduce negative environmental impacts, <br />and reduce conflicts with inhabited and developed areas. Selection of <br />this tentative alignment is based on data shown on U.S.G.S. quadrangle <br />maps. <br /> <br />Plan I. Plan I has approximately 565 miles of conveyance appurte- <br />nances, including 21 pumping plants. Figure 8 shows the proposed plan <br />with Figures 10, 11, and 12 showing the hydraulic profile. The canal <br />is designed to accommodate 1,960,000 acre-feet (includes estimated <br />losses) from two sites, the Bodcau and Naples sites. The canal dimen- <br />sions and design flows are shown by reach in Table 6. <br /> <br />016 <br />
