Aspinall Unit operations update: Gunnison River through Black Canyon streamflow to increase to 1100 cfs

From email from Reclamation Erik Knight:

Releases from Crystal Dam will be increased from 600 cfs to 1100 cfs on Monday, November 16th. The purpose of this increase is to lower Blue Mesa Reservoir down towards the winter icing target. The current content of Blue Mesa Reservoir is 673,000 acre-feet which is 81% full.

Flows in the lower Gunnison River are currently above the baseflow target of 1050 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 1050 cfs for the remainder of the year.

Currently, there are no diversions into the Gunnison Tunnel and flows in the Gunnison River through the Black Canyon are 600 cfs. After this release change Gunnison Tunnel diversions will still be at 0 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.
