An email I just recieved:
Yesterday, a combination of Morrow Point Releases and high side-inflows caused Crystal Reservoir to spill and flows in the Black Canyon and Gunnison Gorge to reach over 7,000 cfs by this morning. Flows at Delta are currently in the 12,000 cfs range. The May 1st forecast for the April through July runoff into Blue Mesa Reservoir is 690,000 ac-ft. consequently, the Black Canyon Water Right calls for a 24 hr peak flow of almost 6,000 cfs (5,864 cfs according to the decree). This flow was achieved starting at about 16:45 May 12th. To insure a 24 hour peak is obtained and to make efficient use of water, Reclamation will start to slowly ramp down releases today. As a result, the spill at Crystal will start to subside and probably be complete by Sunday May 17th. A more detailed schedule is being developed and additional information will be distributed as it becomes available.
