New River, despite its name, is part of the oldest river system in North America. Two streams flowing from the Blue Ridge Mountains in North Carolina join to form the river, which flows through rugged backcountry gorges. Large populations of muskie, catfish, black crappie, perch, bluegill, sunfish and bass provide anglers with plentiful catches in New River State Park.
The New River flows in a generally south-to-north course, at times cutting across the southwest-to-northeast-trending ridges and geological texture of the Appalachian Mountains, and flows directly across the Appalachian Plateau, contrasting with the west-to-east flow of most other major rivers to the east and northeast in Virginia and North Carolina, and on the west side of the Appalachians on the Plateau.
