<br />Water Year 1992 <br /> <br />By December 1992, Blue Mesa Reservoir will bc drawn down 10 <br />at least an elevation of 7495.0 acre-feet in order to minimize icing <br />problems in the Gunnison Ri.....-er. Blue Mesa wiU continue to be <br />drawn down through April of 1992 to the level that will <br />acconunodate the most probable inflow scenario and accomplish <br />the reJc-ase objectives with a minimum of powerplant b)'p3sses. <br />Under all but the most adverse. innow scenarios, Blue Mesa is <br />expected to fill in the summer of 1992. The filling of the reservoir <br />next year will insure that reasonable specific releases required to <br />study the protection and improvement of habitat for endangered <br />fish can be made. The forecasted runoff during the spring of !992 <br />will be constantly monitored to achieve these objectives. <br /> <br />Morrow Point Reservoir releases are expected (0 fluctuate up to <br />powerplanl capacity during ""-ter year 1992. Cr)"tal Reservoir <br />will be operated to regulate releases from MotrCl.W Point <br />Reservoir, (0 meet dO\ll11stream requirements for diversions <br />through the Gunnison Tunnel, and to protect the blue ribbon <br />Iroul fishery in the Black Canyon. Releases arc carefully planned <br />to minimize large monthly changes in flow below the Gunnison <br />Tunnel Diversion. The forccasled runoffduring the spring of 1992 <br />\\!ill be constantly monitored to achieve this objective. <br /> <br />Assuming most probable inflow conditions, releases from Cr)"tal <br />Reservoir will range from 1,200 cubic feet per second to the <br />maximum capacity of 4,200 cubic feet per second. <br /> <br />ACTUAL BLUE MESA STORAGE 1991 <br /> <br />THOUSAND ACRE-FEET <br />'00 <br /> <br /> .... <br /> I7 "" <br /> / ~ <br />./ <br /> <br />.00 <br /> <br />700 <br /> <br />.00 <br /> <br />'00 <br /> <br />'00 <br />ONDJFMAMJJAS <br /> <br />PROJECTED CRYSTAL RELEASES 1992 <br /> <br />THOUSAND ACRE-FEET <br />'00 <br /> <br /> , <br />...
