Black Volta

The Black Volta, also known as the Mouhoun, is a river in Burkina Faso that flows for 1,352 kilometers (840 miles) to the White Volta near Dagbon, Ghana, at the upper end of Lake Volta. The Black Volta River is the country's second-longest river. The Black Volta originates in Burkina Faso's Cascades Region, close to Mount Tenakourou, the country's highest peak.

The Black Volta's source is in Burkina Faso, and it flows north and east until it turns south, forming the border between Ghana and Burkina Faso, and then between Ghana and Côte d'Ivoire. It is the dividing line between the Savannah and Bono regions of Ghana. The Bui Dam, a hydroelectric power plant built on the river immediately south of Bui National Park, which the river bisects, is located on the river. Lawra and Bamboi are the two largest towns on the river in Ghana, with the latter offering river ferry services.

Length: 840 miles (shared with Burkina Faso and Ivory Coast)
