The Leon Watershed, located in the southeastern portion of Wyoming, covers an area of approximately 2,059 square miles. The watershed is dominated by rangeland and is characterized by steep terrain, with elevations ranging from 4,000 to 12,000 feet. The hydrology of the watershed is controlled by snowmelt and summer thunderstorms, with peak flows occurring in May and June. The watershed is also home to several small reservoirs, which are used for irrigation and recreation. The snowpack in the watershed is typically deep, with an average snow water equivalent of 19 inches. The surface water quality in the watershed is generally good, with low levels of pollutants. Interesting climatic facts include the tendency for the area to experience both extreme cold and hot temperatures, and a precipitation pattern that favors summer thunderstorms over winter snowfall. There is evidence of a warming trend in the region, which could impact snowpack and water availability in the future.
