The Upper Amargosa Watershed covers an area of approximately 1,216 square miles in Nevada and California. The hydrology of the watershed is primarily influenced by the Amargosa River and its tributaries, which are fed by seasonal snowmelt and occasional rainfall. In terms of specific snowpack, the watershed is located in a region that receives relatively low annual snowfall, with an average depth of approximately 5 inches. Surface water in the region is limited, with the Amargosa River being the primary source. There are no significant reservoirs within the watershed. Interesting climatic facts include the region's arid climate, with average annual precipitation of only 5-6 inches, and high temperatures during the summer months, with average highs in the mid-90s°F. Climate trends in the region suggest a decrease in precipitation and snowpack, indicating a potential for increased drought conditions.
