Summit County: Denver Water focused on filling reservoir

With inflow to Dillon Reservoir dropping substantially from last week, Denver Water is focusing on topping off the water storage area – which means cutting the outflow through the dam from about 1,600 cfs to about 1,350 cfs. The reservoir level is 1.21 feet below the spillway.

The inflow to the reservoir dropped to 1,446 cubic feet per second Sunday, and the reservoir elevation dropped 0.09 feet. Early last week, inflows had nearly reached 2,200 cfs, but by the end of the week had dropped to just over 1,950 cfs.

When the reservoir fills completely, Denver Water will have to release as much water out of the reservoir as is flowing into it.

The utility company kept outflows at just under 1,900 cfs – slightly more than the lower Blue River’s 1,800 cfs capacity – last week in an attempt to avoid releasing heavier flows downstream when the reservoir fills.

Bob Steger, Denver Water’s manager of raw water, said he’s leaning toward additional cuts in the outflow this week, but decisions won’t be made until the day a change is made.
