The Palisades Watershed (HUC 17040104) covers an area of approximately 1,496 square miles in northwest Wyoming and eastern Idaho. The watershed is dominated by the Snake River, which provides important surface water resources for irrigation and hydropower generation. The hydrology of the watershed is influenced by the mountainous terrain and a specific snowpack, which melts in the spring and feeds the river with its runoff. The Palisades Reservoir is an important feature, providing storage for irrigation and hydropower generation. The reservoir's constituents are largely agricultural and municipal runoff, with some industrial sources. Interesting climatic facts include the region's high snowfall, averaging over 300 inches per year in some areas, and its variable precipitation patterns, with some years experiencing drought conditions. In recent years, warming temperatures have led to concerns about declining snowpack and increased wildfire risk in the region.
