Crystal Reservoir Releases - Revised
August 26, 2014

Releases from Crystal Dam will be reduced from 1800 cfs to 1600 cfs on Tuesday, August 26th at 4:00 PM. Flows in the lower Gunnison River are currently above the baseflow target of 1500 cfs. Significant rainfall has been occurring in the basin this week and the river forecast shows flows continuing to remain above the target for the 10 day forecast period.

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 1500 cfs for August. For September, the baseflow target will be 1050 cfs. 

Currently, diversions into the Gunnison Tunnel are 1100 cfs and flows in the Gunnison River through the Black Canyon are around 750 cfs. After this release change Gunnison Tunnel diversions will still be 1100 cfs and flows in the Gunnison River through the Black Canyon should be around 550 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.
