The Muddy Watershed (HUC 14070002) is located in southeastern Nevada and southwestern Utah, with a total land area of approximately 3,500 square miles. The hydrology of the watershed is dominated by the Muddy River, which flows into Lake Mead. The watershed receives relatively low precipitation, with most of it occurring as snowfall in the higher elevations during winter. The snowpack in the watershed is important for maintaining streamflow during the dry summer months. Surface water in the watershed is used for agricultural and urban purposes, and the main reservoirs are Lake Mead and Lake Mohave. The water quality in the watershed is impacted by high levels of sediment and nutrients from agricultural and urban runoff. The climate in the watershed is characterized by hot summers and mild winters, with occasional periods of drought. Climate change is expected to exacerbate the already dry conditions in the watershed, leading to increased water scarcity and potential impacts on agriculture and urban development.
