Roanoke River
The Roanoke River () is a river in southern Virginia and northeastern North Carolina in the United States, 410 mi (660 km) long. A major river of the southeastern United States, it drains a largely rural area of the coastal plain from the eastern edge of the Appalachian Mountains southeast across the Piedmont to Albemarle Sound. An important river throughout the history of the United States, it was the site of early settlement in the Virginia Colony and the Carolina Colony. An 81 mile section of its lower course in Virginia between the Leesville Lake and Kerr Lake is known as the Staunton River, pronounced STAN-ten, as is the Shenandoah Valley city of that name. It is impounded along much of its middle course to form a chain of reservoirs.
==Description==
The river has its headwaters in the Blue Ridge Mountains in southwestern Virginia at Lafayette in Montgomery County where the North Fork and South Fork of the river merge. The North Fork, approximately 30 mi (50 km) long, rises between two mountain ridges and flows initially southwest, then loops back to the northeast. The South Fork, approximately 20 mi (30 km) long, rises in several streams in the mountains on the border of Floyd, Roanoke, and Montgomery counties and flows generally north, joining the North Fork from the south.
The combined stream flows northeast between mountain ridges through the Roanoke Valley, approximately 10 mi (15 km) to Salem, then east through the city of Roanoke, emerging from a gorge in the Blue Ridge Mountains southeast of Roanoke and forming the boundary between Franklin and Bedford counties. The river flows generally east-southeast across the Piedmont of southern Virginia and enters northeastern North Carolina, passing north of Roanoke Rapids at the fall line. The river flows southeast in a zigzag course across the coastal plain through the Roanoke River National Wildlife Refuge and then briefly turns north as it enters Batchelor Bay on the western end Albemarle Sound.
The river is impounded in three locations. The first is the Niagara dam just south of the City of Roanoke in Roanoke County adjacent to the town of Vinton. It was constructed in 1906 to supply power for the Roanoke Electric Car streetcar system. It is currently owned and operated by the Appalachian Power Company. It is then impounded twice in succession in the Piedmont of southwestern Virginia downstream from Roanoke to form the Smith Mountain Lake and Leesville Lake reservoirs. Farther downstream in southern Mecklenburg County along the North Carolina border, the river is impounded to form the expansive Kerr Lake. In northeastern North Carolina, 3 mi (5 km) west of Roanoke Rapids, the river is impounded to form the Lake Gaston reservoir, which stretches upstream into Virginia to the John H. Kerr Dam, and is impounded a final time to form Roanoke Rapids Lake.
