From The Vail Daily (Scott Miller):

According to an email from Diane Johnson, the communications and public affairs manager for the Eagle River Water & Sanitation District, the Feb. 28 snowpack on Vail Mountain exceeded the peak reached in April of 2018.

The news is better still in other areas.

Peter Goble of the Colorado Climate Center at Colorado State University said there are places in the state — particularly in the southwest — where snow so far has already exceeded the historic averages…

Goble added that Copper Mountain’s snowpack is already at 88 percent of its historic peak. That’s good news, since March and April are the snowiest months in this area…

Dennis Phillips, a forecaster at the Grand Junction office of the National Weather Service, said a combination of bigger weather patterns is bringing a combination of moisture and cool air to the area.

The moisture is coming off the Pacific Ocean via the southwestern U.S. Meanwhile, the jet stream has dropped, bringing cold air in the region. That adds up to a good chance of both snow, and temperatures cool enough to keep that snow on the ground.

Forecasters a few weeks ago declared an official “El Nino” weather pattern in the Pacific. Those patterns often bring storms to Southern Colorado and the Front Range.

Phillips said he suspects the most recent storm was due to something called a Madden-Julian oscillation. Those patterns can last between 30 and 90 days, and will often pump moist air from the Pacific to the U.S…

Colorado Drought Monitor March 5, 2019.

The current snow throughout the state has prompted the Colorado Climate Center to downgrade the severity of drought conditions through most of the state.

Eagle County is still listed as being in a “severe” drought. But the southwest part of the state is no longer in the “exceptional” drought conditions that have lingered for more than a year.

Goble said forecasters at the state climate office have been cautious about downgrading drought conditions through the winter, waiting to see what this season and the spring bring, from sudden heat to wind-driven dust on snow that can accelerate the seasonal melt.

“But at this point, we’re extremely optimistic that drought (conditions) will improve in the Summit and Eagle County areas,” Goble said.

And, while spring is coming, we need the snow that falls to stick around on area hillsides.

Johnson in an email noted that cold temperatures are helping this year, especially compared to the same period in 2018.

“Lack of snow was bad enough, but warm weather really had it melting,” she wrote.

From The Kiowa County Press (Chris Sorensen):

One week after extreme drought made a nearly complete retreat from Colorado, severe conditions were also in sharp decline in the state.

At the start of the water year October 1, nearly half of Colorado was in extreme or exceptional drought, the two worst categories. This week, extreme drought is absent, less than one percent of the state is under extreme conditions, and severe drought dropped from 35 percent to 12 percent. Western Colorado continues to see the most significant improvements as frequent winter storms blanket the area under increased snowpack.

Severe drought now mainly covers south central Colorado, interrupted by a pocket of moderate conditions in the San Luis Valley. Remaining exceptional conditions are in southeast La Plata and Costilla counties, southern Archuleta County, and a sliver of southwest Las Animas County.

Parts of Moffat and Routt counties, along with nearly all of Jackson County, saw moderate drought drop to abnormally dry conditions. Parts of a few eastern Colorado counties also saw moderate drought shift to abnormally dry. Southern Douglas and central Elbert counties were the prime beneficiaries, in addition to northern El Pass and a small portion of west central Lincoln counties.

Overall, 11 percent of the state is drought-free, while 31 percent is abnormally dry, up from 27 percent one week ago. Forty-six percent of Colorado is experiencing moderate drought, up from 27 percent, with 12 percent in severe conditions, down from 34 percent. Extreme drought was steady at less than one percent of the state.

One year ago, 10 percent of Colorado was drought-free, with 19 percent abnormally dry. Twenty-five percent was in moderate drought, while 37 percent experienced severe conditions. The remaining nine percent was in exceptional drought.

Snowpack continues to increase, improving snow water equivalent measurements for this time of year. Statewide, snow water equivalent – the measure of liquid water available in the snowpack – stood at 127 percent of the median, up from 114 percent February 28. Individual basins across the state ranged from 118 to 136 percent of the median. The Gunnison and San Miguel, Dolores, Animas and San Juan basins were strongest at 136 percent, a substantial improvement from the mid-70s two months ago, while the Arkansas basin followed at 134 percent.

Potential San Luis Valley water export topic of Saguache County Board of Commissioners “working meeting” March 12, 2019

Saguache Creek

From The Valley Courier (Teresa Benns):

A group of county residents is appealing to those concerned about water issues in the county to attend an important water meeting March 12 at 6:30 p.m. at the Road and Bridge Building in Saguache, 305 3rd Street, to sit in on a discussion with commissioners regarding water export plans.

The meeting is styled as “a listening work session,” meaning no public comment or questions will be allowed. The guest speaker is Sean Tonner, who will host a water export proposal presentation…

The water plan, apparently in the works for the past several years, was officially announced during a Rio Grande Water Conservation meeting in Alamosa, the Valley Courier reported Dec. 7, 2018…


While some of those proposing the plan are newly arrived players, the proposal is not. The plan first emerged in the late 1980s with Maurice Strong’s Arizona Land and Cattle Co. and Stockmen’s Water. After reorganizing as AWDI, the new version of the plan was opposed and defeated in the early 1990s by the Rio Grande Water District and Valley citizens.

Originally AWDI, backed by then Baca Ranch owner Gary Boyce — also owner of numerous other water rights — presented a plan to pump 200,000 acre-feet of water annually from the underground aquifer. They claimed there would be no impact on the environment or existing water users. The application was later amended to 60,000 acre-feet annually, (approximately twice the amount consumed yearly by the City of Pueblo).

The new version of the water transport plan was most recently run past Saguache County Commissioners in 2014, prior to the death of Baca Ranch owner Gary Boyce. The entity then proposing the water was Sustainable Water Resources (SWR), now retitled as Renewable Water Resources (RWR). The new company is a mix of the previous organization and new members, a media advisor for the group said Tuesday.
