From email from Reclamation (Erik Knight):

Due to the continuance of precipitation throughout the Gunnison River basin, flows in the lower Gunnison River, as measured at the Whitewater gage, have remained above the Aspinall Unit ROD baseflow target of 890 cfs. Scattered rainfall is forecast to occur over the basin during the next week, which will hopefully keep streamflows at or above their current levels.

Therefore, in order to conserve some storage in the Aspinall Unit, releases from Crystal Dam shall be decreased by 50 cfs (from 1,600 cfs to 1,550 cfs) at 8:00 am, Saturday, August 3rd. This will bring flows in the Gunnison River through the Black Canyon down to around 550 cfs.
