While the snowpack in the Yellowstone River basin is average for this time of the year, it’s significantly lower in the Big Horn Basin.
As of Monday, the snow water equivalent (SWE) was down slightly in the Yellowstone area at 99% of median, down from 106% on Jan. 25, 2020. But the snowfall is off in the Bighorn River basin nearly 40% from the same date last year, standing at 79% of median now, compared to 119% in 2020.
In many Wyoming basins, snowpack totals are still generally below the normal figures for this time of year, said Jim Fahey, a Wyoming Natural Resources Conservation Service hydrologist out of Casper.
“The best chance for mountain snow will be in northwest Wyoming by the end of the week into next weekend,” Fahey said.
Across the state, Wyoming’s snowpack/snow water equivalents (SWEs) was 78% of median with the Yellowstone River basin representing a high of 99%, with the South Platte basin, at 16%, being the basin low. Last year the state median average was at 108%.
The Yellowstone and Shoshone River basins are the only regions in the state with SWEs better than 88%.
