<br />'e WayneN, Aspinall Unit, formerly the
<br />;urecanti Unit, includes Blue Mesa, Morrow
<br />'J\nt, and Crystal Reservoirs Blue Mesa
<br />lrovides nearly all of the long-term regulation
<br />1r all three powerplants Morrow Point
<br />'ovides peaking power. and Ihus has highly
<br />3.riable releases. The primary function of
<br />:rystal Reservoir is to re-regulate the variable
<br />~orrow Point releases.
<br />
<br />,t the end of September 1980. Blue Mesa
<br />:eservoir contained 738.000 acre-feet of
<br />clive storage with a wafer surface elevation
<br />f 7.509 feet. The April through July 1981
<br />moff above Blue Mesa was 283.000 acre-
<br />,et, 37 percent of the long-term average, The
<br />ater surface elevation of Blue Mesa reached
<br />maximum of 7,470 feet in June 1981, with a
<br />orage of 433,000 acre-feet. No water by-
<br />3.ssed the powerplant during water year
<br />)81
<br />
<br />1e draw-down for power operations and river
<br />gulation was great enough that no further
<br />lace evacuation for flood control was
<br />quired.
<br />
<br />Jring water year 1981. all flows in the
<br />mnison River below the Gunnison Tunnel
<br />He greater than 200 fPls, the minimum
<br />;cnarge required to protect the fishery in the
<br />er,
<br />
<br />Water Year 1982
<br />Assuming average inflow for water year 1982,
<br />Slue Mesa Reservoir is expected to reach a
<br />low of 7 ,439 feet with an active storage at
<br />approximateiy 255.000 acre-feet in March,
<br />The projected maximum level is 7.509 feet
<br />with an active storage of 735,000 acre-teet.
<br />
<br />Morrow Point Reservoir will operate at or near
<br />its capacity during the current year. Crystal
<br />Reservoir will also operate nearly full except
<br />for daily fluctuations needed in regulating the
<br />releases from Morrow Point and 10 meet
<br />downstream requirements for fish habitat and
<br />diversions thmugh the Gunnison Tunnel.
<br />
<br />Assuming average, or greater runoff
<br />conditions, releases from Crystal Reservoir
<br />will be maintained belween 750 11'15 and 2,000
<br />fP/s. Under lower quartile runoff conditions, or
<br />less, releases will range from the minimum of
<br />200 fl'ls to a maximum of 1,200 fl'/s,
