Ledge Creek is a predominately rural watershed located in Granville and Wake Counties, NC. The Ledge Creek watershed, which includes Creedmoor and Lake Rogers, has more wetlands than any other watershed in the Upper Neuse Basin.
Ledge Creek is not currently identified by the State as an "impaired stream"; however, sediment is becoming a problem in Lake Rogers, Creedmoor's source of drinking water. The lake's sediment level is so high that the City of Creedmoor is currently seeking $6 million in funding from the U.S. Army Corps of Engineers to dredge the lake and increase its drinking water supply capacity.
NCDWQ will conduct investigations this year to determine causes of impairment. A major source of stress to watersheds is impervious surfaces (such as rooftops, driveways, and roads), which prevent water from infiltrating into the ground. When it rains, more water flows over land, picking up pollutants and sediment, eroding stream banks, backing up into sewer systems, and generally making a mess of the stream. Even low levels of impervious land cover (10 to 15%) can degrade streams.
