Watershed Hydrology

The Clear Watershed (HUC 10190004) is located in the northern part of Idaho, covering an area of approximately 2,221 square miles. The watershed is characterized by mountainous terrain, with elevations ranging from 2,000 to 9,000 feet. The hydrology of the basin is driven by precipitation and snowmelt, with snowpack accumulation typically occurring between December and April. The snowpack is critical for the watershed's water supply, providing approximately 60% of the annual streamflow. The surface water in the basin is dominated by small streams and tributaries that flow into the Clearwater River. A few small reservoirs are also present in the watershed. Interesting climatic trends include an increase in average annual temperature and a decrease in snowpack accumulation over the past few decades. These trends could have implications for water availability and ecosystem health in the future.
