From email from Reclamation (Erik Knight):
Releases from the Aspinall Unit will be increased to 1450 cfs on Thursday, April 9th. Releases are being adjusted to accommodate the change in diversions to the Gunnison Tunnel, which will occur on Friday, April 10th. Snowpack in the Upper Gunnison Basin is currently at 101% of normal. The April 1st runoff forecast for Blue Mesa Reservoir predicts 78% of average for April-July inflows.
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 April and May.
Currently, Gunnison Tunnel diversions are 720 cfs and flows in the Gunnison River through the Black Canyon are around 430 cfs. After this release change Gunnison Tunnel diversions will be around 920 cfs and flows in the Gunnison River through the Black Canyon will be around 530 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
