Lake Volta

world's largest man-made reservoir by surface area, located in Ghana

Lake Volta is a large lake in Ghana, west Africa. Humans created the lake in 1964 by building the Akosombo Dam on the Volta River. The dam generates hydroelectric power from falling water.

A map of the Volta River and Lake Volta

Lake Volta's area is about 8,500 square kilometres (3,300 sq mi). It holds about 149 cubic kilometres (36 cu mi) of water. The Black Volta, White Volta, and Oti Rivers flow into the lake. The whole lake is a reservoir along the Volta River. When the water level is lower, the northern parts become more like a river and less like a lake. The area of the lake shrinks and it becomes narrower. The water level is the highest in August to September, and the lowest in May to July.[1]
