From email from Reclamation (Dan Crabtree):
The Uncompahgre Valley Water Users will be changing diversions at the Gunnison Tunnel tomorrow morning, June 2nd and Crystal releases will be adjusted accordingly. This operation may cause the Gunnison River to “bounce” slightly. Flows should be stabile again by afternoon at 650 cfs. If you have any questions please contact Dan Crabtree at 970-248-0652.
