Summit County’s snowpack sits slightly below normal and is among the best in Colorado
Summit Daily News
Snowpack in the Blue River Basin, which encompasses all of Summit County, stood at 90% of the 30-year median as of Friday. The figure shows that Summit is in a good position compared to the state as a whole, which sat at 58% of the median.
Aldis Strautins, a service hydrologist with the National Weather Service in Boulder, said that 90% of the median is “within normal ranges.” He added that some lower elevation areas of Summit County, like the 9,350 foot-elevation snow telemetry monitoring site at Summit Ranch, have already melted out or gotten close.
“Some of the higher sites, like your Copper Mountain and Fremont Pass, those are still doing fairly well,” Strautins said. “Still have quite a bit of snowpack up there, which would make sense for this time of year.”
Snowpack conditions in the winter and spring help water officials predict reservoir health for the summer, and Denver Water wrote in a newsletter in April it was “reasonably confident” the Dillon Reservoir will fill in 2025, allowing the Dillon and Frisco marinas to open on time.
The Dillon Reservoir currently sits at 84% of its capacity, according to the Denver Water website.
Elsewhere in Colorado, Strautins said the southern part of the state has worse snowpack than the north. A recent storm gave that area some snow — but not enough to add to the overall snowpack because of how much had melted out before the storm, he said.
“(Interstate) 70 south is just well below normal for this time of year,” Strautins said. “I-70 north, some areas are below normal and slightly below normal, and then a few areas are still around the normal range.”
The upper Colorado Headwaters River Basin, which includes Summit County, is close to normal, “and that’s about it,” Strautins said.
Looking ahead, Strautins did not see any storms in the short-term forecast that would add to the snowpack. He said the next four-to-five days of warming temperatures will melt snowpack and increase flows in rivers in Summit County and elsewhere.
River flows will likely peak around May 14 before cooler temperatures return and slow the flow, Strautins said.
Strautins did not see significant storms coming in the long-term forecast either, though he said it is hard to predict if a storm will produce enough snow to affect the snowpack very far in advance.
“Right now, the trend is probably not to increase any of the snowpack,” Strautins said. “We might get a little bit of snow, but just to really increase the snowpack — I just don’t see anything coming right now in the forecast.”
