As winter transitions to spring in the high country, the Upper Gunnison Basin might be heading into a warm and dry spell and holds at about average for the year on snowpack. A three-month forecast is predicting spring might be (mostly) here to stay, with warmer and drier weather to come. Spring runoff may be kicking into high gear in the next few weeks as the layers of dust within the snowpack from two recent wind events could lead to a faster melt off period as well…According to Upper Gunnison River Water Conservancy District (UGRWCD) senior program manager Beverly Richards, soil saturation and weather could make a difference for spring runoff season.

“The soil moisture at this time is a little dryer than this time last year so the combination may have an effect on runoff amounts and timing,” she said.

Drought conditions around the basin range from absent to moderate. As of April 2, 53% of Gunnison County was experiencing no drought conditions, and 47% of the county was experiencing abnormally dry to moderate drought conditions. In the 129-year record, this winter (January to February) was the 56th wettest year and February was the 64th driest, Richards said…

As of April 8, precipitation has ranged from 50% to 150% of normal in the county over the past 30 days, and a small portion in the southeastern corner of the county measured up to 200% of normal during the same period.

According to the National Resources Conservation Service (NRCS) the Upper Gunnison Basin snow water equivalent (SWE) as of April 7 has been measured as 116% of normal overall.  Specific locations measured as follows: 125% of normal at the Upper Taylor River location; 122% of normal at the Butte location; 107% of normal at Schofield; 126% of normal at Park Cone; 127% of normal at Porphyry Creek; and 92% of normal at Slumgullion.

Blue Mesa Reservoir is projected to fill to about 85% this spring. Reservoir storage for the entire Gunnison Basin is at 63% of average, and 65% for the Upper Gunnison Basin. The Bureau of Reclamation (BOR) has projected that Blue Mesa will fill to 85% in 2024. The National Park Service reported that Elk Creek boat ramp at Blue Mesa opened on April 11, and the reservoir was at 7,485 feet elevation as of April 10. This is about 34 feet (10 meters) below full pool at 7,519 feet (2291 meters). The BOR has reported that among reservoirs in the Upper Colorado River Basin, the Flaming Gorge is 86% full; Fontenelle is 33% full; Morrow Point is 94% full, Blue Mesa is 66% full, Navajo is 65% full, Lake Powell is 33% full and total storage across the basin is at 63%.
