Snowpack, river levels below median despite ‘good’ March

Posted

On April 30, the National Weather Service (NWS) released its drought outlook for May, which states “the last 4 weeks brought improvement to areas of drought in most of the Rockies and Intermountain West.”

The outlook depicts much of New Mexico still with areas of persistent drought along with small portions of southern Colorado, including Archuleta County. 

Pagosa Area Water and Sanitation District Engineer/Manager Justin Ramsey explained in an interview that water is still flowing into the district’s Fourmile diversion.

“There’s still a lot of snow up there, so we’re in good shape for now,” he said. “March was a good month … helped us out quite a bit.”

According to the U.S. Drought Monitor, as of noon on April 30, all of Archuleta County is in an abnormally dry stage, with southwestern parts of the county in a D1 Level Moderate drought.

Snowpack

Snowpack levels across the state were up at the start of April due to “late-season snowstorms and consistent precipitation,” according to an April 9 press release from the Natural Resource Conservation Service (NRCS). 

The state’s snowpack was at 114 percent of median on April 9, but, as of April 30, the state’s snowpack had fallen to 91 percent of median.

Pagosa Country received a mix of precipitation last weekend, with higher elevations seeing snow and lower elevations getting some rain, graupel and some snow. 

According to Shawn Prochazka at Pagosa Weather, based on SNOTEL data, the top of Wolf Creek Pass received about 5 to 7 inches of snow from Friday, April 26, to Sunday, April 28.

As of 11 a.m. on Tuesday, April 30, the Wolf Creek summit, at 11,000 feet of elevation, had 21.8 inches of snow water equivalent, according to NRCS.

The Wolf Creek summit was at 63 percent of the April 30 snowpack median.

The San Miguel, Dolores, Animas and San Juan river basins were at 64 percent of median, according to the NRCS. The median snowpack peak date is April 2.

The South Platte basin had the highest snow water equivalent in the state at 104 percent of median as of Tuesday, April 30.
