The Black Bear Red Rock Watershed covers an area of approximately 556 square miles in southern Nevada. It is part of the larger Colorado River Basin and is primarily characterized by the Mojave Desert ecosystem. The hydrology of the watershed is dominated by intermittent streams and washes, with the largest permanent water source being Lake Mohave. The snowpack in the area is generally limited, with most precipitation falling as rain. Surface water quality in the watershed is generally good, with some concerns about sedimentation from nearby mining activities. There are no major reservoirs within the watershed. Interesting climatic facts include the extreme temperatures typical of the desert environment, with average high temperatures in the summer often exceeding 100 degrees Fahrenheit. Climate change is expected to exacerbate drought conditions in the region in the coming years, with potential impacts on water resources and wildlife populations.
