From The Summit Daily (Taylor Sienkiewicz):

Despite a drier spring than Summit County saw last year, the Blue River basin’s snowpack total is well above the seasonal average. Treste Huse, a senior hydrologist for the National Weather Service in Boulder, said the Blue River basin sits with 120% of the average for snow-water equivalent, or how much water is held in the snowpack.

Huse said the water in the Blue River basin snowpack is well above average for this time of year. The snowpack in the basin holds about 19.3 inches of water, compared with the average 15.7 inches of water that the basin’s snowpack typically holds this time of year…

Huse said that the majority of storms this year have come from the northwest and have favored the north central mountains, missing the southern mountains. The U.S. Drought Monitor’s national drought summary, which was last recorded April 21, reports that severe drought has expanded over most of southern Colorado. The Colorado Climate Center at Colorado State University’s April 21 update lists the eastern plains of Colorado as an area of concern and reported that snowmelt in the Four Corners region has “kicked into high gear” and is melting faster and earlier than normal…

Going over the year in precipitation amounts, Huse said Summit County had a good October, November was fairly dry and then precipitation accumulation amounts shot up in December. She reported that February into March was great for precipitation as February saw record snowfall amounts at some of the ski areas.

Precipitation has leveled off in April with small storms bringing little accumulation aside from one recent storm system that brought 1.4 inches of snow-water equivalent. Huse said the snowpack levels were above average going into April, but the recent storm helped bring the numbers even higher.

The Blue River basin nears the end of the precipitation cycle toward the end of April. Huse said the weather service looks at yearly precipitation from July 1 through the end of June. She said that on April 17, Dillon’s total snowfall was around 102.1 inches while normal seasonal snowfall is 107 inches, putting Dillon just a few inches shy of the average snowfall total but ahead of average for mid-April. Huse said that at this time of year, the average snowfall amount in Dillon is 94.5 inches.

As she reported in early March, Huse said snowfall totals are above average but not abnormal. She said this is the 77th highest amount of snowfall for a year in Dillon out of 112 years. The highest annual snowfall Dillon has recorded was in 1935 when the town saw 227 inches of snow.

While water in the snowpack is above average this year, Huse said the late-season precipitation is not nearly as high as 2019, which was an anomaly. She reported that while the snow-water equivalent is around 19.3 inches this year, in 2019 the Blue River basin had around 21.2 inches.
