Snake

Watershed Hydrology

The Snake watershed (HUC 07030004) covers an area of approximately 109,000 square kilometers and encompasses parts of Wyoming, Idaho, Nevada, and Oregon. The hydrology of the watershed is heavily influenced by snowpack, with significant winter snow accumulation followed by spring snowmelt. The Snake River is the main surface water feature and is used for irrigation, drinking water, and hydropower generation. The reservoirs in the watershed, including Palisades, Jackson, and American Falls, are used for water storage and flood control. The climate of the Snake watershed is classified as continental, with cold winters and hot summers. Interestingly, the region experiences some of the largest temperature fluctuations in the United States, with daily temperature swings sometimes exceeding 50 degrees Fahrenheit. In recent years, the Snake watershed has experienced warming temperatures and decreased snowpack, leading to concerns over water availability and potential impacts on agriculture and other water-dependent industries.
