VIRGINIA RESERVOIR REPORT

Last Updated: December 21, 2025

Virginia has numerous reservoirs and dams that serve as sources of drinking water, recreation, and hydroelectric power generation. Some of the major reservoirs in the state include Smith Mountain Lake, Lake Anna, and Lake Gaston. These reservoirs are fed by various streams, rivers, and creeks, including the Roanoke River, the North Anna River, and the Roanoke Rapids. The hydrology of the area is influenced by the Appalachian Mountains, which receive significant snowfall during the winter months. This snowpack contributes to streamflow during the spring and summer months, which in turn helps to fill the reservoirs. However, drought conditions can also impact the water levels in these reservoirs, as was seen in the early 2000s when severe drought led to record low water levels in many of Virginia's reservoirs. Seasonal trends in Virginia's reservoirs are largely dependent on precipitation patterns. During the wetter months, water levels in the reservoirs tend to rise, while during the drier months, water levels may drop. Overall, Virginia's reservoirs play a crucial role in the state's water supply and are closely monitored to ensure adequate water resources for the surrounding communities.
