The Upper Tennessee River watershed covers three rivers in Virginia: the Clinch, Holston, and Powell rivers. The Roundtable is active in water quality improvement efforts in all three of these rivers. The greater watershed is host to numerous species of fish, mussel, and other aquatic life species. In fact, according to the Nature Conservancy, the Upper Tennessee River watershed greatly exceeds all other watersheds in the lower 48 states in terms of species richness and diversity!
