Dillon Reservoir inflows have peaked and slowed, and in response Denver Water has decreased outflows into the Blue River.
The utility decreased the water flow into the river Tuesday, June 17, from 1,000 cfs to 800 cfs in its fourth decrease in a week. The reservoir is about 90 percent full, Travis Thompson, senior media coordinator for Denver Water, said on Tuesday.
Depending on the weather, the utility will allow the reservoir to rise another 8 feet in the next two weeks, about half a foot a day, to be full by July 4.
Thompson said the reservoir’s level was about the same at this time last year, but historically the level is closer to 97 percent full by mid-June. Inflows are still above average.
After Front Range flooding last September and a winter with above-average snowpack, he said, Denver Water realized in early March that it needed to release water into the Blue River to avoid flooding Silverthorne later in the season.
“We’re doing this on purpose,” he said. “We took those proactive steps early.”
The utility’s No.1 priority is to fill the reservoir, but it also considers flood risk and recreational use.
