NWS: Wyoming Water Levels Remain Above Average in April
Forecasters with the National Weather Service in Riverton say Wyoming’s water supply remains well above average for the month of April.
Hydrologist Jim Fahey says statewide precipitation levels last month were above 130 percent of average. Precipitation levels last month ranged between 203 percent of average near the upper Yellowstone watershed, to 80 percent near the Cheyenne and Niobrara basins.
Fahey also says statewide mountain snowpack is moderately above average, currently ranging somewhere between 130 and 140 percent. Snowpack levels range from 145 to 160 percent in northcentral Wyoming, to around 110 to 120 percent in southwest Wyoming.
“We’re coming into our snow-accumulation springtime, especially east of the divide, so a lot can happen between now and when the snow melts in earnest in early June,” Fahey said.
A couple areas of the state, however, remain somewhat dry.
“South fork Shoshone and the north fork of the Shoshone River south and west of Cody, and we’re looking at some problem areas on the western slopes of the Bighorn Mountains east of Worland and east of Greybull,” Fahey said.
Fahey also says, currently, statewide reservoir storage is ranging between five and ten percent below average.
