From email from Reclamation (Erik Knight):

Releases from Crystal Dam will be decreased from 1250 cfs to 1150 cfs on Wednesday, October 15th at 8:00 AM. Releases are being decreased to time with the brown trout spawn. Flows in the lower Gunnison River are currently above the baseflow target of 1050 cfs. River flows have remained relatively high due to the September rains and flows are expected to stay above the October 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 September through December.

Currently, diversions into the Gunnison Tunnel are around 800 cfs and flows in the Gunnison River through the Black Canyon are around 450 cfs. After this release change Gunnison Tunnel diversions will still be around 800 cfs and flows in the Gunnison River through the Black Canyon will be around 350 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
