<br />NAVAJO RESERVOIR <br />(SAN JUAN RIVER) <br /> <br />Water Year 1994 <br /> <br />The elevation of Navajo Reservoir at the beginning of the <br />water year was 1853.3 meters (6080.3 feet) with 2,003 million <br />cubic meters (1,624,000 acre-feet) of live storage (96 percent <br />of capacity). At the end of water year 1994, the elevation <br />was 1848.4 meters (6064.4 feet) with 1,728 million cubic <br />meters (1,401,000 acre-feet) of live storage (82 percent of <br />capacity). <br /> <br />Actual inflow to Navajo Reservoir for water year 1994 was <br />1,133 million cubic meters (918,756 acre-feet), 96 percent of <br />normal. Peak inflow into Navajo Reservoir occurred on <br />June 22, 1994, at 175 cubic meters per second (6173 cubic <br />feet per second). The reservoir reached a peak elevation of <br />1854.0 meters (6082.7 feet) on May 2, 1994. The April <br />through July inflow into Navajo Reservoir in water year 1994 <br />was 767 million cubic meters (622,209 acre-feet) or 94 <br />percent of average. <br /> <br />ACT1JAL RELEASES IBM <br /> <br />--- <br />100 <br /> <br />--- <br />- <br /> <br /> -II P <br /> 17 <br />J \ <br />7 1'\ <br /> " <br /> ....

Water <br />year 1994 was the fourth year of a 7-year study to evaluate <br />alternative operations of Navajo Reservoir to benefit <br />endangered fISh. In accordance with this 7-year study, spring <br />operations of Navajo were modified in 1994 and large <br />releases of up to 127.4 cubic meters per second (4,500 cubic <br />feet per second) were made during much of May and June <br />to coincide with the peak flows of the Animas River to study <br />the effect of large spring flows on the habitat improvement <br />and spawning success of endangered endemic species of fISh. <br />This resulted in flows of over 241 cubic meters per second <br />(8,500 cubic feet per second) at Bluff, Utah. After the <br />completion of the large spring releases, flows were reduced <br />to approximately 17.0 cubic meters per second (600 cubic <br />feet per second) for the remainder of the year. <br /> <br />NAVAJO 'RESERVOIR <br /> <br />Rcsen'Oir <br /> <br />Slorago Capacity <br />Nonnal Pool Elevation <br />Surface Aru. full <br />R.uervoir Length, rull <br /> <br />2,092 million cubic meten (1,696,400 acre-feet) <br />1854.6 melen (6Q8S,O reel) <br />6,317 hecta.a (15,610 .crea) <br />53 kilomctcn (33 milea) <br /> <br />11 <br />
