April Was a Wet Month

The National Weather Service yesterday released the May water supply outlook for Wyoming, which reports that April precipitation was 115 to 120 percent of average. That percentage is identical to the current water year precipitation across Wyoming.

Precipitation numbers varied between 160 percent of normal over the Snake and Upper Green River Drainages to near 80 percent of average over the Big Horn River Basin.

Mountain snowpack across the state is 90 to 100 percent of median, and near normal to slightly above normal snowmelt streamflow volumes are still expected across several major basins in Wyoming. Above average snowmelt volumes are expected across the Shoshone, Upper Bear, Upper North Platte, and Laramie Watersheds.

Total reservoir capacity across Wyoming continues to be 75 to 80 percent at this point in the month. Reservoir storages, however, remain above average across the state at 115 to 120 percent.
