Basin precipitation, snow pack levels remain below average
Date posted: March 12, 2013
SHERIDAN — Wyoming basin precipitation and snow pack levels remained slightly below average in February, according to figures released this week by the National Oceanic and Atmospheric Administration.
Basin precipitation checked in between 85 and 90 percent of average across Wyoming while snow pack measured between 80 and 85 percent of average. Still, normal stream flow volumes are expected across a majority of Wyoming’s watersheds with reservoir storages at near average levels for early March.
February precipitation numbers varied between 153 percent of normal in the Tongue River basin to 49 percent of normal in the upper Green River drainage.
Stream flow snowmelt volumes are expected to be below normal across a majority of basins across Wyoming.
Near normal — 90 to 99 percent — stream flow volumes are expected across portions of the Powder, Big Horn and Shoshone Watersheds.
Upcoming spring precipitation levels will play a large part in determining whether certain areas of the state will be particularly susceptible to fire damage during the summer. Currently, well below spring and early summer snowmelt volumes are expected for a majority of watersheds across southern Wyoming.
