The South Fork Shoshone watershed covers a land area of approximately 2,736 square kilometers in northwest Wyoming. The hydrology of the watershed is dominated by snowmelt and precipitation, with the South Fork of the Shoshone River and its tributaries providing most of the surface water. The snowpack in the watershed is an important source of water for the region, with the peak snowpack typically occurring in April. The watershed contains several reservoirs, including Buffalo Bill Reservoir, which can store up to 1.25 million acre-feet of water. The reservoirs are used for irrigation, hydropower generation, and flood control. The climate of the watershed is characterized by cold winters and warm summers, with an average annual precipitation of approximately 450 millimeters. Recent trends suggest that the region is experiencing a warming climate, with earlier snowmelt and increased variability in precipitation.
