Sen. Udall helps secure funding for snow surveys

NRCS snow surveys help water managers plan ahead.

Temporary budget fix ensures program through August 2014

By Bob Berwyn

FRISCO — For decades, hydrologists have been tromping through the high country of Colorado and around the West to make detailed snowpack measurements. Together with data from automated SNOTEL sites and other tools, the monthly snow-course readings help water managers develop accurate projections of spring stream flows, and  how much water will be available for irrigation and storage.

The information is critical in arid regions, which rely on the winter snowpack as the ultimate reservoir. Federal budget cuts have threatened the program, raising concern among western resource managers, but the U.S. Department of Agriculture announced this week that it has found a way to maintain funding for the Snow Survey and Water Supply Forecasting Program — at least through the end of Aug. 2014.

Colorado snowpack lingering in the northern mountains

Southern part of state still gripped by drought

Colorado’s June 5 snowpack map is a patchwork quilt of contrasts.

By Summit Voice

FRISCO — Springtime in the Rockies was a tale of two states in Colorado. The snowpack rebounded in the northern mountains, which benefited from a series of wet spring storms, but the southern half of the state was dry and warm, with serious drought conditions persisting in the Rio Grande, as as the San Miguel, Dolores, Animas and San Juan basins.

This year’s statewide snowpack peaked April 21, several weeks later than the average date, and cool weather helped further delay snowmelt across the higher elevations, resulting in a statewide June 1 snowpack  at 92 percent of median, according to Randy Randall, acting State Conservationist with the NRCS.

“This respectable percentage is due mainly to the generous amount of snow that remains across northern Colorado. In contrast, the snowpack in the southern portion of the state is nearly depleted even at the higher elevations,” Randall said. Continue reading

Colorado snowpack inches upward in March

Some drought-hit areas stay dry

Summit County, western Eagle County and parts of Colorado’s northeastern plains saw well above-average precipitation in March, but much of the rest of the state was very dry.

Drought conditions persist at some level across all of Colorado as of late March.

SUMMIT COUNTY — Colorado’s snowpack continues to inch upward and recently passed last year’s level, but the state’s water woes aren’t over, according to the results of the latest Natural Resources Conservation Service snow survey.

The good news is that the snowpack hasn’t quite peaked yet, according to the April 1 compilation of statistics from automated SNOTEL sites and manual survey results. The bad news is that soil moisture in many parts of the state is still at drought levels, and reservoir levels are well below average and lagging behind last year.

While March snowfall was above average in some parts of Colorado, the statewide snowpack increased by only one percent during the month, from 73 percent of median on March 1, to 74 percent of median on April 1. Continue reading

Summit County: Snowpack drops to near half of average

Southeast Colorado sets December snowfall records

By Bob Berwyn

SUMMIT COUNTY — Snowpack in the Blue River Basin, encompassing all of Summit County’s rivers and streams, is quickly dropping down toward just half of the long-term average for early January.

According to the January 6 readings from automated SNOTEL sites around the basin, the snowpack at Copper Mountain is just 55 percent of average, with only 3.4 inches of snow-water equivalent, compared to the average 6.2 inches for this date. The Copper SNOTEL site is located at 10,550 feet.

Precipitation for the  weather year-to-date (starting Oct. 1) is a little closer to average, at 68 percent, with 5.2 inches compared to the average 7.7 inches, but the gap between the precipitation total and the snowpack total reflects the warm and dry weather which has eaten away at the snowpack.

Weather: December one of the driest in recent years

Front Range moisture helps ease demand for West Slope water

The snowpack across much of northwest Colorado has dipped below 70 percent of average.

The eight to 14-day outlook from the Climate Prediction Center.

SUMMIT COUNTY — The lack of snowfall in the high country is starting to show in the snowpack readings across the western part of the state, where readings have fallen below 70 percent of average — about 67 percent in the Colorado River Basin, which means that the snowpack is about one-third less than the average for this time of year.

In a strange twist on the La Niña weather pattern, the Front Range snowpack is above average, which doesn’t directly help the spring runoff on which much of the state depends. But good winter moisture on the Front Range does help ease demand for stored water, at least early in the season.

If there’s good news, it’s the above-average snowpack in the Upper Rio Grande Basin in south-central Colorado, where moisture hasn’t been over-abundant the past few years. A full list of SNOTEL site snow depth readings in online here. Continue reading

Colorado: June 1 snowpack at record levels nearly statewide

Snowpack across much of Colorado was at record levels as of June 1.

Runoff in some northwestern river basins expected to be two to three times of average

By Summit Voice

Colorado’s latest snowpack data, compiled by the Natural Resources Conservation Service, shows the profound impact that a cool and wet May can have on water supplies, in terms of both timing and quantity.

The forecasted runoff throughout the Yampa, White, Colorado, North and South Platte river basins this year is well above average, and in some cases will be two to three times higher than the average for the April through July forecast period.

“There remains a tremendous amount of snow across northern Colorado. A gradual and even meltout would help minimize impacts”, said state conservationist Allen Green. Continue reading

Unsettled pattern to persist through mid-week

Even a roadside mud puddle looks good with some fresh snow. May 21. Frisco, Colorado.

Readings from automated SNOTEL sites show a snowpack that's twice average for this date across large parts of the West.

By Bob Berwyn

SUMMIT COUNTY — Saturday’s storm dropped another 13 inches of snow at A-Basin, pushing the base back up over 100 inches with a 48-hour snow total of 20 inches — and it looks like Ullr isn’t quite done with us yet.

Showery weather is forecast to persist through mid-week, with another chance for significant snow early in the coming week, through with warmer temperatures, most of the accumulations will be confined to the higher elevations.

Specifically, there’s enough moisture in the airmass over the high country to fuel convective showers and thunder storms Sunday afternoon, when the high temperature will reach about 50 degrees, 9 degrees below the average. The record high for the date is 74 degrees, set just a few years ago, in 2005. And before we feel to sorry for ourselves, consider that the record low for the date (in Frisco) is zero, set way back in 1933. Continue reading
