<br />", <br /> <br />July and August, when releases would <br />be needed from Hay Gulch Reservoir <br />to supplement the flows from Ridges <br />Basin Canal. Hay Gulch Reservoir <br />would store excess La Plata River <br />flows. The La Plata'Diversion <br />Dam and Canal would divert water to <br />Hay Gulch. <br /> <br />The Lower Animas Canal would <br />be located about four miles below the <br />Durango Pumping Plant and would di-. <br />vert water from the Animas River <br />by gravity to Southern Ute Reservoir. <br />This water would be used for indus- <br />trial purposes on the Southern Ute <br />Indian Reservation and for irriga- <br />tion in New Mexico. The Lower <br />Animas Canal would irrigate by <br />gravity the Southern Ute Indian <br />lands near the reservoir. Irriga- <br />tio~ water for the New Mexico <br />lands would be conveyed from the <br />Southern Ute Reservoir by the New <br />Mexico Irrigation Canal. Sprinkler <br />irrigation would be provided to <br />the Third Terrace and Tunnel Ditch <br />areas of New Mexico. Pressure in <br />most of these two areas would be <br />provided by the slope of the ground; <br />only one small pumping plant would <br />be required to supply pressure for <br />part of the Third Terrace area. <br /> <br />The proposed Animas Power <br />Plant would generate power to be <br />used along with supplemental pur- <br />chases from CRSP to provide power for <br />project pumping. Animas River flows <br />would be diverted from the river <br />channel into a 1,750-cfs capacity <br />tunnel; a minimum 50-cfs bypass has <br />been assumed as necessary in all <br />current studies. The tunnel inlet <br />would be located on the first sharp <br />bend south of the Tacoma Power <br />Plant. The tunnel would convey <br />water from the inlet to a penstock, <br />which would lead to the power plant, <br /> <br />The power plant would be recessed <br />in the canyon wall so that it <br />would not detract from the area's <br />scenery. <br /> <br />Sprinkler irrigation is <br />planned for all project areas <br />except the La Plata, New Mexico <br />area; the La Plata, Colorado area <br />above Ridges Basin Canal; and the <br />Southern Ute Indian lands around <br />Southern Ute Reservoir. The <br />lateral systems would provide <br />sprinkler pressure of 45 to 100 <br />psi at the far:n tu:-nouts. Pun:ping <br />plants would provide this pressure <br />where the ground slope was in- <br />sufficient to pressurize the pipe- <br />line. Project drainage also would <br />be provided. <br /> <br />Fisheries would be created <br />in the inactive pool of project <br />reservoirs and recreational faci- <br />lities would be provided at each <br />reservoir. .A miriimum stream by- <br />pass of 100 cfs is planned below <br />both the Durango Pumping Plant <br />and the Lower Animas Diversion <br />Canal, except when the natural <br />flow drops below 100 cfs. <br /> <br />SCHEDULE <br /> <br />The Definite Plan Report and <br />Draft Environmental Statement are <br />scheduled for completion by Sep- <br />tember 1976. The Final Environ- <br />mental Statement should be avail- <br />able in January 1977. <br /> <br />.. <br />
