<br /> <br />. <br /> <br />CHAPI'ER II <br /> <br />PLAN OF DEVELOPMENT <br /> <br />Project purposes <br /> <br />The San Miguel project would regulate unused flows of the San Miguel <br />River for irrigation, municipal and industrial use, flood control, recrea- <br />tion, and fish and wildlife conservation. The project would provide an <br />average of 77,800 acre-feet of water annual~ for the irrigation of 38,950 <br />acres of land, including 26,420 acres not presently irrigated and 12,530 <br />acres in need of supplemental water. About 44,000 acre-feet of water <br />annual~ would be made available for municipal and industrial use. A <br />flow of at least 25 second-feet would be maintained for fish in the San <br />Miguel River below the point of project storage and diversion, and 500 <br />acre-feet of water annual~ would be provided to maintain a 200-acre wild- <br />life area. Recreation facilities would be provided at project reservoirs. <br /> <br />. <br /> <br />Pro.iect Plan <br /> <br />The Saltado Reservoir would be constructed on the San Miguel River <br />to store the flows of that stream. A system of canals and laterals, <br />heading at the reservoir and general~ following the southern perimeter <br />of the project land area, would convey water to places of use for irri- <br />gation and some municipal and industrial uses. The canals would also con- <br />vey water for further regulation in the offstream Naturita and Radium <br />Reservoirs. <br /> <br />Saltado Rese.'voir and Norwood Canal <br /> <br />The Saltado Reservoir with a capacity of 72,600 acre-feet would be <br />formed by a dam at a point 12 miles southeast of Norwood. The reservoir <br />would extend upstream 4.5 miles from the dam, inundating the small com- <br />munity of Placerville. Reservoir releases would be made to the river for <br />preproject rights, some project uses for municipal and industrial purposes, <br />and maintenance and enhancement of the stream fishery. <br /> <br /> <br />. <br /> <br />Project water for irrigation and some municipal and industrial uses <br />would be released at the north abutment of Saltado Dam into the Norwood <br />Canal which would cross to the south side of the canyon by siphon and ex- <br />tend westward about 22 miles to the Naturita Reservoir. The upper 11.4 <br />miles of the canal would consist of a series of tunnels and siphons pierc- <br />ing the wall of the deep gorge in which the river flows and crossing deep <br />canyons of tributary streams. At the outlet of the last tunnel atop Nor- <br />wood Mesa part of the canal water would be released into the potential <br /> <br />14 <br />
