The South Fork Salmon Watershed (HUC 17060208) covers an area of approximately 1,577 square miles in Idaho. The watershed is mountainous and is characterized by rugged terrain, high elevations, and steep slopes. The area receives a significant amount of snow in the winter, which contributes to the hydrology of the watershed. The snowpack in the South Fork Salmon Watershed is an important source of surface water in the spring and summer months. The watershed is also home to several reservoirs, which are used for irrigation, flood control, and recreation. The constituents of these reservoirs vary, but they typically contain sediment, nutrients, and other pollutants. Interesting climatic facts include the area's high precipitation levels and cold temperatures, which can range from -20 degrees Fahrenheit in the winter to 100 degrees Fahrenheit in the summer. Climate change is causing changes in the snowpack, which could impact the availability of water in the watershed.
