From email from Reclamation (Erik Knight):

Significant rainfall in the North Fork of the Gunnison basin has changed things considerably over the last 24 hours. What was predicted to be a 1,500 cfs peak at the Somerset gage turned into a 2,600 cfs peak last night, with over 4,000 cfs in the North Fork at the confluence gage. This resulted in flows reaching 5,800 cfs on the Gunnison River at the Whitewater gage, above the peak flow target of 4,991 cfs.

Currently flows in the Gunnison River through the Black Canyon are 1,050 cfs so release at Crystal Dam will continue to be increased in order to reach the Black Canyon Water Right peak flow target of 2,054 cfs. The peak release for the Black Canyon Water Right will be maintained for 24 hours before releases are ramped down, starting late Saturday night, May 9th. The updated release schedule is shown below:
