Crystal Reservoir Releases - Revised
April 15, 2015
Releases from Crystal Dam will be increased from 1050 cfs to 1150 cfs on Wednesday, April 15th at 9:00 AM. This release increase is in response to an increase in diversion to the Gunnison Tunnel. The current forecast for April-July unregulated inflow to Blue Mesa Reservoir is 480,000 acre-feet which is 71% of average.
Flows in the lower Gunnison River are currently above the baseflow target of 1050 cfs. River flows are expected to stay above the baseflow target for the foreseeable future.
Pursuant to the Aspinall Unit Operations Record of Decision (ROD), the baseflow target in the lower Gunnison River, as measured at the Whitewater gage, is 1050 cfs for April.
Currently, diversions into the Gunnison Tunnel are 700 cfs and flows in the Gunnison River through the Black Canyon are around 350 cfs. After this release change Gunnison Tunnel diversions will be around 800 cfs and flows in the Gunnison River through the Black Canyon should be around 350 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
This scheduled release change is subject to changes in river flows and weather conditions.
