The East Fork Sevier Watershed covers approximately 1,700 square miles in southern Utah and northern Arizona. The hydrology of the area is primarily influenced by snowpack, with the highest elevations receiving up to 500 inches of snow annually. This snowpack gradually melts and feeds into the surface water system, including the East Fork Sevier River and several reservoirs. The water in these reservoirs contains high levels of sediment and nutrients, which can create challenges for water treatment facilities. The area experiences a semi-arid climate, with the majority of precipitation falling as snow in the winter months. In recent years, the region has seen a trend towards drier and hotter conditions, with prolonged droughts becoming more common. These shifts in climate pose significant challenges for water management in the watershed.
