From email from Reclamation (Conor Felletter):

On Monday, June 16th, the scheduled releases from Crystal Dam will decrease to 1,400 cfs. This release change is intended to conserve water amidst the increasingly hot & dry conditions in the Gunnison basin while downstream tributaries are still providing enough water to keep the lower Gunnison River above the baseflow target.

Gunnison River flows (Black Canyon/Gunnison Gorge) are currently 520 cfs and will decrease to ~420 cfs.

Releases are made for the authorized purposes of the Aspinall Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the Gunnison (near Whitewater).  Future release changes are subject to changes in river flows and weather conditions. 

Thank you,
