Blackwater River (Virginia)

The Blackwater River of southeastern Virginia flows from its source near the city of Petersburg, Virginia for about 105 miles (170 km) through the Inner Coastal Plain region of Virginia (part of the Atlantic Coastal Plain). The Blackwater joins the Nottoway River to form the Chowan River, which empties into Albemarle Sound. The Blackwater-Nottoway confluence forms the boundary between Virginia and North Carolina.
