Upper James

Watershed Hydrology

The Upper James Watershed, located in western Virginia, covers an area of approximately 1,821 square miles. The watershed is primarily fed by precipitation, which contributes to the hydrology of the area. The region experiences cold winters and hot summers, resulting in a specific snowpack that can influence the watershed's surface water. The watershed includes several reservoirs, including the Smith Mountain Lake, which was created by a dam on the Roanoke River. The reservoirs are essential for providing water to local communities, and they also serve as popular recreational destinations. Climatic trends in the area have shown increased precipitation and warmer temperatures over the last several decades. These trends may have significant impacts on the watershed's hydrology and surface water in the future. The Upper James Watershed is an important resource for the surrounding communities, providing water, recreation, and wildlife habitat.
