From email from Reclamation (Erik Knight):
Releases from the Aspinall Unit will be increased to 1600 cfs on Monday, December 9th. Blue Mesa Reservoir elevation remains above the winter icing target level. Releases will be maintained at this level with the goal of lowering the reservoir to the icing target elevation of 7490 feet by December 31st. 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 September through December.
Currently, there are no diversions into the Gunnison Tunnel 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 zero and flows in the Gunnison River through the Black Canyon will be around 1600 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
