The
Sassandra River is a river of western
Côte d'Ivoire in
West Africa. It is formed by the confluence of the Tienba River, which originates in the highlands of northwestern Côte d'Ivoire, and the Gouan River (also known as the Bafing Sud River), which originates to the west in the highlands of
Guinea. The Sassandra flows south-southeast to empty into the
Gulf of Guinea on the
Atlantic Ocean. The
Buyo Dam was constructed across the middle stretch of the river in 1980, just below the confluence with the Nzo River, to create the reservoir called
Lake Buyo. The Davo River joins the Sassandra just before it meets the sea. The
port town of
Sassandra lies on the seacoast where the river meets the sea.
