From email from Reclamation (Erik Knight):
Flows in the Gunnison River at the Whitewater gage continue to fluctuate with the periodic rainfall. Reclamation intends to meet the flow target of 900 cfs at the Whitewater gage through the end of July. The target will drop to 890 cfs starting August 1st. Releases from Crystal Dam will continue to cause flows in the Gunnison River through the Black Canyon to fluctuate between 500 cfs and 600 cfs.
