From email from Reclamation (Eric Knight):
Releases from Crystal Dam will be decreased from 2000 cfs to 1800 cfs on Wednesday, August 10th. July inflows to Blue Mesa Reservoir ended up being less than predicted and August inflow forecasts are also declining. The April-July runoff volume finished the season at 89% of average. The current content of Blue Mesa Reservoir is 757,000 acre-feet which is 91% full.
Flows in the lower Gunnison River are currently above the baseflow target of 1050 cfs. Flows are expected to remain 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 August through December.
Currently, diversions into the Gunnison Tunnel are around 1000 cfs and flows in the Gunnison River through the Black Canyon are around 1000 cfs. After this release change Gunnison Tunnel diversions will still be at 1000 cfs and flows in the Gunnison River through the Black Canyon should be around 800 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
