From email from Reclamation (Erik Knight):

While this may appear to be an accidental resend of yesterday’s notice, it is in fact another notice of a release increase for the Aspinall Unit. The bottomless well of snowmelt and precipitation continues to hold inflows into Blue Mesa Reservoir above all predictions. Maybe one day inflows will actually decrease but it certainly wasn’t yesterday. Therefore releases from Crystal Dam will be increased by a total of 400 cfs over the next 2 days. This increase will be done in 200 cfs increments, one this afternoon, Thursday, July 14th, and one early Friday morning, July 15th. Flows in the Gunnison River through the Black Canyon are expected to increase from 2950 cfs to around 3350 cfs by Friday, July 15th. This change will put Crystal Dam at full powerplant and bypass releases. Any further increases will mostly likely result in a spill at Crystal Dam. This is not expected to occur but there is a possibility if inflows continue at their current level.
