Crystal Reservoir Releases - Revised
June 22, 2015
Releases from the Aspinall Unit will be increased by 500 cfs this afternoon, Monday, June 22nd. Morrow Point Dam will be increasing releases by 500 cfs which will increase the total release at Crystal to 8000 cfs. This release increase is in response to the high water levels at Blue Mesa and Morrow Point Reservoirs. Inflows to Blue Mesa Reservoir are still over 6000 cfs although the forecast suggests flow levels should be past their peak. The current forecast for April-July unregulated inflow to Blue Mesa Reservoir is now 650,000 acre-feet which is 96% of average.
Flows in the lower Gunnison River are currently above the baseflow target of 1500 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 1500 cfs for June and July.
Currently, diversions into the Gunnison Tunnel are near 900 cfs and flows in the Gunnison River through the Black Canyon are over 7000 cfs. After this release change Gunnison Tunnel diversions will be about 900 cfs and flows in the Gunnison River through the Black Canyon will be over 7500 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.
