Project Description

Clinch and Powell Rivers

Ecosystem Services was contracted by the Nature Conservancy of Virginia to delineate the Waters of the U.S. on recently purchased properties on the Clinch and Powell River in Washington and Lee Counties, respectively. These properties contain significant frontages on the Clinch and Powell Rivers, as well as endangered ecosystems endemic to the area, such as Limestone and Dolomite Barrens.

The biodiversity of the Clinch is of global significance. The Clinch River watershed supports more rare species of freshwater mussels and fish than any river system in North America.
