Crystal Reservoir Releases - Revised
March 20, 2015

Releases from Crystal Dam will be decreased from 600 cfs to 500 cfs on Friday, March 20th at 8:00 AM.  This release decrease is in response to increasing flows on the lower Gunnison River. The current forecast for April-July unregulated inflow to Blue Mesa Reservoir is 590,000 acre-feet which is 87% 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 March.

Currently, diversions into the Gunnison Tunnel are zero and flows in the Gunnison River through the Black Canyon are around 600 cfs. After this release change Gunnison Tunnel diversions will still be zero and flows in the Gunnison River through the Black Canyon should be around 500 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.
