From The Durango Herald (Jonathan Romeo):
“I think, unfortunately, it’s one of those years that’s kind of a bummer,” said Ashley Nielson, a senior hydrologist with the Colorado River Basin Forecast Center. “Everything is going to be below average.”
Snowpack in the San Juan Mountains this winter hovered near historic averages, according to Snotel sites, which track snow depth.
But Snotel sites tell only part of the story.
For one, there are a limited number of sites in the basin. And this year, elevations above most Snotel sites around 11,000 feet didn’t receive as much snow as usual.
To make matters worse, drought conditions last summer and fall caused the ground to dry up significantly, so soil likely will absorb more snowmelt than normal, at the expense of rivers and streams.
As a result, the Colorado River Basin Forecast Center predicts the Animas River will receive about 70% of the water it usually does in spring, Nielson said.
The forecast center also predicts the Animas River likely will hit a peak flow of 2,300 to 2,500 cubic feet per second, though as much as 3,000 cfs is possible…
As of Friday, Snotel records show Southwest Colorado’s snowpack is melting at an accelerated rate: Snowpack in the San Juans is 70% of normal historic averages for this time of year.
Jarrod Biggs, assistant utilities director for the city of Durango, said a heavy snowpack year in the winter of 2018-19 provided good storage for the town’s reservoir, which should help water reserves during a below-normal runoff.
The city of Durango gets most of its water from the Florida River and supplements supply from the Animas River when demand increases…
Water is not being pulled from the Animas River to Lake Nighthorse this year, said Russ Means, general manager of the reservoir, as crews work on the intake structure across from Santa Rita Park.
On Friday, the Animas River was running at 1,700 cfs, which is 25% higher than average for this time of year, said Frank Kugel, director of the Southwestern Water Conservation District.
