Aspinall Unit update: 400 cfs in the Black Canyon


From email from Reclamation (Erik Knight):

With the recent rains, flows in the Gunnison River at the Whitewater gage are well above the September baseflow target of 890 cfs. Short term forecasts predict flows will stay above 1000 cfs while the baseflow target for October drops down to 790 cfs. Considering all this, releases from Crystal Dam will be reduced on Saturday, September 29th, with the intention of maintaining 400 cfs in the Gunnison River through the Black Canyon (down from the current flow of 480 cfs).

In the next couple weeks, decreasing irrigation demands will result in less diversion into the Gunnison Tunnel which may necessitate changes at Crystal Dam. Releases may be reduced further in light of the lower Whitewater gage baseflow target for October if rainfall and tributary flows continue to support flows in the lower mainstem of the Gunnison River.
