From email from Reclamation (Dan Crabtree):
The rain came through this weekend and flows at the Whitewater gage have now reached 1400 cfs. Rain is expected to continue today and then taper off by Wednesday. Diversions at the Gunnison Tunnel are also decreasing by 50 cfs this morning. In order to further water conservation in the Aspinall Unit reservoirs, we will match the tunnel decrease from Crystal Dam plus an additional decrease of 100 cfs because of the higher flows at the Whitewater gage. After this change, flows in the Gunnison River through the Black Canyon should drop to about 520 cfs.
