The Middle Roanoke Watershed (HUC 03010102) covers an area of approximately 2,419 square miles in southwestern Virginia. The region is characterized by its high elevation and mountainous terrain, which contributes to a complex hydrology system. The watershed receives an average of 42 inches of precipitation each year, with snowfall being a significant contributor during the winter months. The Appalachian Mountains in the region act as a significant water source, supplying numerous streams and rivers that ultimately drain into the Roanoke River. Surface water quality in the Middle Roanoke Watershed is influenced by the presence of multiple reservoirs throughout the region. These reservoirs are essential for water supply, recreation, and hydropower generation. Climatic data for the region indicates that temperatures have been gradually increasing over the past century, with a corresponding decrease in annual snowfall. This trend has implications for water availability, as snowpack serves as a natural storage mechanism for water in the region.
