From email from Reclamation (Erik Knight):
Releases from Crystal Dam will be decreased from 3700 cfs to 2000 cfs between July 2nd and July 6th. Releases will be decreased by 200 cfs today, and then by 400 cfs each day over the next 3 days, with a final decrease of 300 cfs on the morning of July 6th. This reduction is in response to the continuing decline in runoff to the Aspinall Unit reservoirs. The current forecast for April-July unregulated inflow to Blue Mesa Reservoir is now 700,000 acre-feet which is 104% 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 July.
Currently, diversions into the Gunnison Tunnel are around 1000 cfs and flows in the Gunnison River through the Black Canyon are 2800 cfs. After this release change Gunnison Tunnel diversions will be around 1000 cfs and flows in the Gunnison River through the Black Canyon should be around 1100 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
