Reservoir Filling is Short-Lived

The Denver Water Board opened the Roberts Tunnel today for the first time in several months. The Roberts Tunnel channels water from Dillon Reservoir through a 24 mile underground aqueduct under the Continental Divide into the South Platte river near Grants, along Highway 285, and on into storage on the Front Range for Denver Water customers.

The last of the snowpack is melting and flows on the South Platte River have dropped, with downstream demand on the South Platte River growing.

Denver Water engineer Marc Waage said, "By next Monday we will not have raftable flows anymore in the lower Blue River. Things are changing quickly. Inflows into Dillon Reservoir are dropping."

Yesterday the inflow into the Blue River was about 695 cubic feet per second, down from near 1,000 CFPC earlier in the week.
