The Shoshone watershed (HUC 10080014) covers an area of approximately 3,890 square miles in Wyoming. The watershed is primarily mountainous, with elevations ranging from 4,200 to 13,804 feet above sea level. The watershed is fed by the Wind River Range, which is known for its significant snowpack that feeds the headwaters of the Shoshone River. The runoff from this snowpack contributes to the surface water flow, which is used for irrigation, recreation, and wildlife habitat. There are several reservoirs in the watershed that store water for irrigation, including the Boysen and Buffalo Bill reservoirs. The primary constituents of these reservoirs are water, sediment, and nutrients, which can affect the water quality downstream. Interesting climatic facts and trends in the Shoshone watershed include the potential for flash floods in the summer and early fall due to monsoonal moisture, and the increasing frequency and severity of droughts in the region.
