To prevent MRGCD irrigators from diverting deliveries in route to <br />Elephant Butte Reservoir, Cochiti may not release waters from July <br />through October, nor can releases be made when the natural flow into <br />Cochiti Reservoir falls below 1,500 cubic feet per second (cfs). <br /> <br />i c'" <br /> <br />:.;~ <br /> <br />. Of the total capacity, 212,000 af of capacity must remain idle at all <br />times, providing adequate storage for flood water resulting from <br />summer thunderstorms. If inflows fall below 1,500 cfs, releases from <br />Cochiti will still be made to ensure mandatory storage levels are <br />maintained. Thus, the storage requirements outweighs the inflow <br />stipulation regulating releases. <br /> <br />, ;;.:. <br />I". <br /> <br />~,. <br /> <br />In compliance with the requirement for a permanent pool: <br /> <br />:~ .;. <br /> <br />. Adequate amounts of San Juan-Chama water must be retained each <br />year within Cochiti Reservoir to support a permanent pool for <br />recreational purposes as well as supporting fish and wildlife <br />populations. The surface area of the pool shall not be less then <br />1,200 acres. <br /> <br />In compliance with CoE's operating procedures: <br /> <br />" <br /> <br />. Releases from Cochiti Reservoir, combined with those from the Jemez <br />Canyon Dam, shall remain below 7,000 cfs so as not to exceed flood <br />capacity of the river's channel. <br /> <br />. Whenever feasible, releases from these two reservoirs, should be <br />adequate to guarantee enough flow so that water entering the <br />low-flow conveyance channel will travel the entire length of the <br />channel and reach the headwaters of Elephant Butte Reservoir. <br /> <br />Elephant Butte Reservoir <br /> <br />Elephant Butte Reservoir was authorized by Congress in 1905 and completed <br />by the BuRec in 1916 as part of the BuRec's Rio Grande Project. The <br />reservoir, with a capacity of2.1 million af, was designed to secure the annual <br /> <br />A-3 <br /> <br />fC3C39 <br />
