The Lower Owyhee Watershed (HUC 17050110) spans across 4,610 square miles and is situated in Oregon and Idaho. It is characterized by a desert climate with hot summers and mild winters, which results in low precipitation and high evapotranspiration. The watershed is primarily unregulated and relies on snowpack and precipitation for its surface water supply. The snowpack content varies annually, with the average snow water equivalent being around 1.5 inches. The surface water flow is primarily from the Owyhee River and its tributaries, which support a variety of fish and wildlife species. There are no major reservoirs within the watershed, and the primary water users are agricultural and municipal sectors. Climate change is expected to have significant impacts on the watershed, including reduced snowpack and prolonged drought periods.
