Region Info

The James River watershed drains approximately 10,000 square miles of land. The river begins in the Allegheny Mountains, where it is formed by the confluence of the Jackson and Cowpasture Rivers and flows approximately 340 miles to the Chesapeake Bay. Sub-tributaries include the Appomattox, Chickahominy, and Elizabeth Rivers. Land use within the watershed is predominantly forest, with agriculture/farming accounting for approximately one-fifth of land use. Major cities in the watershed include Richmond and Hampton Roads. The census population for 2000 in the watershed was over 2,500,000 people. Based on information in Dauer, et al., 2003 and the James River Association.
