<br />Wayne N. Aspinall Unit
<br />(Gunnison River)
<br />Blue Mesa Reservoir
<br />Morrow Point Reservoir
<br />Crystal Reservoir
<br />
<br />
<br />Water Year 1980
<br />The Wayne N, Aspinall Unit, formerly the
<br />Curecanti Unit, includes Blue Mesa,
<br />Morrow Point, and Crystal Reservoirs.
<br />Blue Mesa provides nearly all of the long-
<br />term regulation for all three powerplants.
<br />Morrow Point provides peaking power
<br />and thus, has highly vanable releases.
<br />The primary function of Crystal Reservoir
<br />is to re-regulate the variable Morrow
<br />Point releases.
<br />
<br />At the end of September 1979, Blue Mesa
<br />Reservoir contained 629,240 acre-feet of
<br />active storage with a water surface eleva-
<br />tion ot-7;506~feet;-The ~April through-July
<br />1980 inflow to Blue Mesa was 961,000
<br />acre-feet, 25 percent grealer than the
<br />long-term average; and the total water
<br />year inflow was 1,208,000 acre-feet. The
<br />water surface elevation of Blue Mesa was
<br />only two-tenths of a foot short of max-
<br />imum elevation in July 1980, No water
<br />bypassed the power plant during water
<br />year 1980,
<br />
<br />The drawdown for power operations and
<br />river regUlation was great enough that no
<br />further space evacuation for flood control
<br />was required.
<br />
<br />During water year 1980, all flows in the
<br />Gunnison River below the Gunnison
<br />Tunnel were greater than 200 ftJ/s, the
<br />minimum discharge required to protect
<br />the fishery in the river.

<br />Water Year 1981
<br />Assuming average Inflow for water
<br />year 1981, Blue Mesa Reservoir is ex-
<br />pected to reach a low of 7,467 feet with
<br />an active storage of approximately 413,000
<br />acre-feet in March. The projected max-
<br />imum level is 7,517 fee1 with an active
<br />storage of 809,000 acre-feet.
<br />
<br />Morrow Point Reservoir will operate at or
<br />near its capacity during the current year.
<br />Crystal Reservoir will also operate nearly
<br />full except for daily fluctuations needed
<br />in regulating the releases tram Morrow
<br />Point to meet diversion requirements
<br />downstream from-fha-Gunnison. Tunnel.
<br />
<br />If the inflow to Blue Mesa Reservoir is at
<br />the upper quartile, the release is expected
<br />to average 2,800 ftJ Is for several weeks
<br />in June and July 1981, For average, lower
<br />quartile and most adverse inflows, a
<br />maximum monthly release of about 1,400
<br />It'ls is projected in July 1981,
