The James Watershed (HUC 11010002) covers an area of approximately 24,000 square miles in Virginia and West Virginia. The watershed is a critical source of drinking water and provides important habitat for aquatic species. Hydrologically, the watershed is characterized by moderate to high streamflow, with an average annual discharge of over 7 billion cubic meters. The region experiences a significant snowpack during the winter months, which contributes to the surface water supply. Several large reservoirs are located within the watershed, including the Smith Mountain Lake, which serves as a primary water source for several nearby communities. Climate trends in the area include an increase in annual precipitation over the past century, as well as more frequent extreme weather events such as droughts and floods. These trends have important implications for water management in the region.
