The Black Volta, known as the Mouhoun in Burkina Faso, is a major river in West Africa that forms significant portions of the international borders between Ghana, Burkina Faso, and Ivory Coast. Originating in western Burkina Faso, the river flows primarily southward, traversing western Ghana before merging with the other Volta branches. It is distinguished by its relatively steady flow throughout the year, making it a reliable resource for hydroelectric power and agricultural activities. The most prominent structure on the river is the Bui Dam, Ghana's second-largest hydroelectric facility, which has created a large reservoir within the Bui National Park. The river's banks are often lined with lush gallery forests that provide a habitat for diverse wildlife, including large populations of hippopotamuses, notably protected at the Wechiau Hippo Sanctuary. The Black Volta is central to the regional economy through commercial fishing and supporting large-scale irrigation schemes. Its dual role in energy production and environmental conservation makes it one of Ghana's most critical water resources.
