The Clearwater Elk Watershed (HUC 07010203) encompasses approximately 862 square miles in north-central Idaho. The watershed is primarily fed by snowpack, and the elevation ranges from 1,500 to 9,000 feet. The Clearwater River is the main surface water feature in the watershed, and it is used for recreation, irrigation, and hydroelectric power. The watershed also contains several reservoirs, including Dworshak Reservoir, which is the third-largest reservoir in Idaho. Climatically, the Clearwater Elk Watershed experiences a semi-arid climate, with hot summers and cold winters. The snowpack is important for the hydrology of the watershed, as it provides water for the river and reservoirs during the summer months. In recent years, the snowpack has been declining due to climate change, which has led to lower river flows and reduced water availability. The reservoirs in the watershed contain high levels of sediment and nutrients, which can lead to water quality issues. Additionally, the reservoirs can be affected by harmful algal blooms, which can be toxic to humans and animals. Efforts are being made to address these issues through improved land management practices and water quality monitoring.
