From the Summit Daily News (Bob Berwyn):

Stream flows in Summit County are not too far off seasonal norms, but the Colorado River at Kremmling recently experienced an all-time record low flow for that date, according to local water commissioner Scott Hummer. The Colorado was only flowing at 280 cubic feet per second on Nov. 16, and flows farther downstream were also well below average, Hummer said. The previous minimum for the date was 330 cfs in 1978. “I can’t find a rhyme or reason as to why we’re starting to see these low flows so early in the season,” Hummer said.

Statewide, and in the Blue River Basin, the snowpack is at 79 percent of average. Only the Arkansas (at 99 percent) and the South Platte (100 percent) have an average snowpack for the date, he said. Some of the higher elevation sites in the Blue River Basin have a decent snowpack, including Fremont Pass, where an automated Snotel site shows the snowpack at 121 percent of average. But lower elevation sites are dry, with Summit Ranch, north of Silverthorne, coming in at just 33 percent of normal.
