Accordingly, the releases from Blue Mesa are <br />regulated in order to draw the storage down to approximately 581,000 acre-feet by January 1 of each <br />year, and then to fill the reservoir by the end of July. Power demands generally control the release and <br />fill patterns in the Aspinall Unit reservoirs. Typically, the schedule for increasing and decreasing release <br />rates is linear, increasing in increments of 50 cfs/day for releases less than 2,000 cfs, and in increments <br />of 250 cfs for releases greater than 2,000 cfs. <br />During the storage period when inflows to Blue Mesa are greater than the releases, including the bypass <br />of inflow to the downstream Gunnison Tunnel, water can be stored pursuant to the Blue Mesa decrees. <br />If, at this time, releases (such as for power generation) are greater than the Gunnison Tunnel demand that <br />is being bypassed through the reservoirs, the releases that are in excess of the Gunnison Tunnel demand <br />are counted against the United State's first fill decree in Blue Mesa Reservoir. When inflows to Blue <br />Mesa decrease to the point that the inflow is less than the Gunnison Tunnel demand (1,135 cfs), <br />additional releases to the tunnel are made from the UVWUA's exchange credit account in Blue Mesa <br />4 <br />A275 01.09.95 1.15-21 Fosha, Hyre <br />
