Both the Dillon Reservoir and the Green Mountain Reservoir are expected to reach capacity this summer, Colorado Division of Water Resources division engineer James Heath said at the State of the River in Silverthorne on Thursday, May 22…An about-normal snowpack in Summit County this winter means both reservoirs are expected to “fill and potentially spill,” Heath said. While the snowpack levels were close to normal, the runoff has been slightly below normal because the county went into last winter with dry soils, he said…
The snowpack in the Colorado River Headwaters Basin peaked April 7, about a week earlier than normal, Heath said. At 89% of the 30-year-median…The Blue River Basin [peaked] April 8, at 108% of the 30-year-median, Heath said…
.Dillon Reservoir should reach an elevation of 9,012 feet by June 18, allowing both the Dillon and Frisco marinas to be fully operational by that time. Outflows…should exceed 500 cubic feet per second — the level ideal for rafting the Blue River — around the third week in June and continue until around the Fourth of July weekend, he said.
