From email from Reclamation (Dan Crabtree):
The Uncompahgre Valley Water Users will be discontinuing their diversions through the Gunnison Tunnel within the next two weeks. Those of you who monitor the gage below the Tunnel via the Internet will be seeing some fluctuations as Reclamation reduces releases from Crystal in response. However flows in the Canyon and Gorge will generally remain in the 500 cfs range for the remainder of October and November. (Currently, the release from Crystal Reservoir is 1,300 cfs.) The latest model runs show that December flows are anticipated to be in the 1,400 cfs range in response to higher power demands and to meet the winter elevation target at Blue Mesa. As always, these flows are subject to change as a result of variable hydrologic conditions. Please contact Dan Crabtree at 970-248-0652.
