Runoff (snowpack) news

From the Summit Daily News (Bob Berwyn):

Flows in the Blue River were very near 1,800 cubic feet per second the past few days. The level prompted a small stream flood advisory, specifically for the Blue River through Silverthorne and northward. Fewer showers are expected today, so flows could moderate slightly. Water commissioner Scott Hummer said the levels aren’t unusual. He said runoff from high elevations, rain and lack of diversions to the Front Range combined to send flows upward during the past week. Denver Water’s East Slope reservoirs are full, so no water is flowing out through Dillon Reservoir’s Roberts Tunnel, which can take as much as 800 cubic feet per second. In the Upper Blue, Colorado Springs has cut diversions through a tunnel under Hoosier Pass “I’m surprised at the flow that’s moving through the reservoir. I didn’t think we’d see those types of flows,” Hummer said.

From The Mountain Mail (Christopher Kolomitz):

In the Arkansas River basin, snowpack was 52 percent of average. Only the North Platte, 55 percent of average and the South Platte, 52 percent, were higher. Colorado River basin was 31 percent of average and the Gunnison River basin was 7 percent of average…

In most Colorado basins, snowmelt is ranging from about two to three weeks earlier than typically expected. For most of the state, summer water supplies are expected to be near average. However, there are several areas which failed to receive enough moisture during the winter and spring to assure near average runoff volume. Those include the San Juan, Animas, Dolores and San Miguel basins of southwestern Colorado.

In the Arkansas River basin, reservoir storage was 99 percent of average and 123 percent of last year. With statewide storage volume at 116 percent of average, these are the best storage statistics since 1999.
