February precipitation totals across Wyoming were 84 to 88 percent of average. Precipitation numbers varied between 182 percent of normal over the Crow/Lodgepole Creek Drainage (extreme southeastern Wyoming) to near 41 percent of normal over the Clarks Fork Yellowstone/Shoshone River Basin (northwestern Wyoming). Current water year (October 2015 – February 2016) precipitation across Wyoming remains near 100 percent of average.

Mountain snowpack across Wyoming continues to be 80 to 85 percent of median by early March. Snowpack "water" numbers and/or SWEs were the highest across basins in southern Wyoming—varying between 95 to 105 percent of median. SWEs across basins in north central Wyoming varied between 55 to 75 percent of median.

Below normal (80 to 85 percent) snowmelt streamflow volumes are expected across almost all major basins across Wyoming. Near average streamflow volumes are expected across portions of the Shoshone Watershed. The Sweetwater, Powder, and Tongue River Basins are still forecasted to have much below normal streamflow volumes during the upcoming snowmelt season.

Reservoirs storages across Wyoming are remained above average at 110 to 120 percent for March.
