(primarily erosion and sedimentation) from land clearing, removal of riparian vegetation, and rural roads are potential problems.
According to an NCDENR dam inventory (NCDEMLR 2014) , there are 49 impoundments in the basin. Most are small privately owned lakes used for recreation, and these small impoundments fragment headwater habitats, contribute to temperature pollution, and can be a source of nonnative introductions. All of the major tributaries in North Carolina are upstream from major impoundments in Georgia and South Carolina that isolate them from the rest of the basin. Short reaches of the Horsepasture and Toxoway rivers are impounded just inside the North Carolina border (Lake Jocassee, Duke Energy).
