The Sheridan County snow pack took a big leap thanks to last week's snow storms.
While the Tongue River and Powder River Basins are still below normal, both are about 15 percent closer to average after the late January snowfall.
But people in Sheridan remain concerned over the snow pack and the impact on water supply levels, especially if the area goes through a second straight dry year.
City officials say they are monitoring the water levels closely and the supply is at a safe amount.
"We have our mountain reservoirs, our Twin Lakes storage. And it's not a problem for a year or two, but we operate in hopes it will fill over the winter," said Water Supply and Treatment Superintendent Tom Manolis.
The Tongue River's drainage is at only 57 percent of last year's level. Conservationists say water content that stays so low would provide significant problems later in the year.
"The reservoir levels may not be entirely full. We might see lower runoff numbers, tougher year for irrigators," said Andrew Cassiday with the Natural Resources Conservation Service.
Wyoming's lowest snow pack is in the southeast where the Lower North Platte Basin is less than 30 percent of average.
