The Paria Watershed (HUC 14070007) covers an area of 1,523 square kilometers in southern Utah and northern Arizona. The watershed is characterized by a semi-arid climate with an average annual precipitation of 261 millimeters. The area is dominated by sandstone formations, and the hydrology is influenced by the Colorado Plateau, with several tributaries feeding into the Paria River. The snowpack in the watershed is typically low, with an average snow water equivalent of 53 millimeters. Surface water is limited, with most of the streamflow occurring as intermittent or ephemeral flow. The watershed contains several reservoirs, including the Glen Canyon and Lake Powell reservoirs. The water in these reservoirs is used for hydropower generation and irrigation. In recent years, the Paria Watershed has experienced a warming trend, with average temperatures increasing by 0.36 degrees Celsius per decade. This trend is expected to continue, leading to possible changes in the hydrology and ecology of the area.
