Upper White

Watershed Hydrology

The Upper White Watershed covers an area of approximately 2,200 square miles in northwestern Wyoming. It is primarily a mountainous region, with elevations ranging from 4,500 to 13,804 feet. The watershed is characterized by alpine terrain and receives heavy snowfall during the winter months, which contributes significantly to its hydrology. The snowpack in this area is highly variable, with an average snow water equivalent of 51 inches. Due to the area's rugged terrain, surface water is primarily found in streams and rivers, with few natural lakes or ponds. The watershed contains several reservoirs, including Buffalo Bill Reservoir and Newton Lakes, which are used for irrigation, hydroelectric power generation, and recreation. In recent years, the Upper White Watershed has experienced changes in precipitation patterns, with warmer temperatures leading to decreased snowpack and earlier snowmelt. These trends have implications for water supply, recreation, and wildlife habitat in the region.
