Gunnison River to reach peak flows May 18
The Bureau of Reclamation announced Monday that flows in the Gunnison River through the Black Canyon will be increased to 3,883 cubic feet per second for a 24-hour period projected for May 18.
Increasing (or ramping up) the flows by about 500 cfs per day should meet the May 18 date, said Dan Crabtree, lead hydrologist for the Bureau’s Grand Junction office.
The peak flows and accompanying shoulder flows are components of the Black Canyon reserved water right. That 2008 settlement includes annual peak flows and shoulder flows — tied to natural inflow — plus a year-round base flow of 300 cubic feet per second.
Once the peak flows are finished, the river will be ramped down by 400 cfs per day to around 800 cfs by for the rest of the summer, Crabtree said.
