The Volta River is the main river system in the West African country of Ghana. It flows south into Ghana from Bobo-Dioulasso highlands of Burkina Faso. The main parts of the river are the Black Volta, the White Volta, and the Red Volta. In the northwest, the Black Volta forms the international borders between the Ivory Coast, Ghana, and Burkina Faso. The Volta flows southward along Akwapim-Togoland highlands, and it empties into the Atlantic Ocean at the Gulf of Guinea at Ada Foah. It has a smaller tributary river, the Oti, which enters Ghana from Togo in the east. The Volta River has been dammed at Akosombo for the purpose of generating hydroelectricity. The reservoir named Lake Volta stretches from Akosombo Dam in the south to the northern part of the country, and is the largest man-made reservoir by area in the world.[4]

Volta was named by the Portuguese, meaning twist or turn.

The reservoir[]

Lake Volta is a reservoir impounded by the Akosombo Dam on the lower Volta River in southern Ghana. It is one of the largest reservoirs in the world. It extends from the Akosombo Dam in southeastern Ghana to the town of Yapei in the Central Gonja District, Northern Region of Ghana, some 400 kilometres (250 mi) to the north.

The dam's power plant generates electricity for the Volta River Authority, and the reservoir also provides water transport routes. It is a resource for irrigation and fish farming.

The depth of the river is about 45 feet (14 m) below Lake Volta. The Volta River is crossed by the Adome Bridge just below the Akosombo Dam.

History[]

The Volta River was named by Portuguese gold traders in Ghana. It was their farthest extent of exploration before returning (volta is Portuguese for "twist" or "turn").[5] "River of return" (perhaps because it was where ships turned around and headed for home) or “river of the bend”, in reference to its curved course.[5][6]
