Here's an article about the snowpack from the Summit Daily News (free registration required). They write, "After a couple of months of so-so snowfall, Mother Nature picked up the pace in February, with total monthly snowfall in downtown Breckenridge edging into the surplus zone for the first time since early in the season. Rick Bly, who measures the white stuff for the National Weather Service, tallied 35 inches for the month, well above the 23.4 inches that's average for the month based on records going back more than a 100 years. The snow melted down to 2.38 inches of water, also well above the average 1.72 inches. Bly said the high winds made it tricky to measure the snowfall totals toward the end of the month. For the season to date, Bly has measured 130.8 inches of snow, making for a 23 percent surplus based largely on the big October dumps that added up to more than three times the normal snowfall for that month...
"February snowfall at the Dillon site was a little below average, with 15.5 inches of snow compared to the average 18.8 inches. The snow melted down to just .72 inches of water, more than 30 percent below the average 1.18 inches. The biggest notable anomaly in the February weather stats is for the temperature readings at the Dillon site, where the average monthly low temperature registered at 7.6 degrees, well above the average 1.3 degrees. The mercury dropped to minus-19 degrees the first two nights of the month, but things warmed up significantly after that, with only three more nights of sub-zero readings. And several nights near the middle of the month were downright balmy for mid-winter, with lows in the mid- and upper-20s. Daytime highs climbed above freezing 17 times, with the warmest reading (50 degrees) on Feb. 7.
"Statewide, snowfall totals continues to hover near average in many basins. The Upper Colorado River Basin was at exactly 100 percent of normal as of March 5, with the lowest reading (77 percent) at Arapaho Ridge, and the highest (117 percent) at Jones Pass. Summit County Snotel site readings include 105 percent at Copper Mountain, 103 percent at Grizzly Peak, 116 percent at Hoosier Pass and 91 percent at Summit Ranch, in the Lower Blue. The moisture content in the Upper Colorado Basin is at 96 percent of normal as of March 5.Snowfall in the Gunnison River Basin stands at 99 percent of normal for the season (beginning Oct. 1), while the Yampa and White River basins are at 90 percent of normal snowfall, with 84 percent moisture content. The San Miguel, Animas, Dolores and San Juan Basin has tallied 99 percent of average snowfall, but the water content in the San Juan snowpack is only at about 76 percent of average for this time of year."
More snowpack news from the Vail Daily News (free registration required). From the article, "On Wednesday, the statewide snowpack was 91 percent of the 30-year average, compared with 88 percent on the same date last year. The Colorado River basin itself was 96 percent of average. The southwest reported the lowest with 77 percent in the San Miguel-Dolores-Animas-San Juan Basin. The blizzards filled up plains reservoirs and Denver Water, the state's biggest municipal water provider, reported its system was 89 percent full as of Monday. The average for the date is 78 percent. The snow also ended two years of extreme drought for wheat farmers. Hanavan said the area entered a drought in 1999 that was only temporarily broken by heavy snow in the spring of 2003. Demand for ethanol has driven up prices for wheat and corn. The 116 percent average reported in the Arkansas River Basin and 111 percent in the South Platte were a mixed blessing. Colorado ranchers lost an estimated 10,000 to 15,000 head of cattle to blizzards. So far the federal government has declined to provide any aid."
Water supplies up north are looking OK, according to the Longmont Daily Times-Call. From the article, "The Natural Resources Conservation Service's March 1 snowpack report, released Monday, shows snowpack for the South Platte River Basin at 111 percent of average. That basin includes the St. Vrain Creek basin, which supplies at least half of Longmont's water. Snowpack estimates show the amount of water in snow, which is important for planning summer water supplies for cities and agricultural producers. The South Platte snowpack decreased 3 percentage points from last month, but no one is raising a red flag about the decline. 'It's not all that alarming,' said Mike Gillespie, a snow-survey supervisor for the NRCS. 'It's been a little on the dry side. The impact of the December and January blizzards has been mitigated a bit.' Ken Huson, water resource administrator for the city of Longmont, said he's optimistic about the March 1 snowpack report as a whole. However, between one-third and one-half of Longmont[base ']s water -- depending on the year -- comes from Windy Gap and Colorado-Big Thompson water-diversion projects, which take Western Slope water from the Upper Colorado River Basin. That basin is 5 percent off its average snowpack readings, according to the NRCS."
