The artificial lake with the greatest area is Lake Volta in Ghana, West Africa. The Bratsk Reservoir on the Angara River in the USSR holds the greatest volume of water in an artificial lake.

In 1965, the Akosombo Dam was completed across the Volta River. The dam is built at the southern end of a gorge and produces hydroelectric power. Lake Volta began to build up behind the dam in the valley of the Volta River and its main headwaters, the Black Volta and the White Volta. Altogether, the lake now covers 3,276 square miles and its shoreline is 4,495 miles long. Villagers had to move from the flooded area to the new shoreline where they began a fishing industry.

Lake Volta is large but fairly shallow. In places, the remains of flooded forests can still be seen. Its total volume is 36 cubic miles - compared to 40 cubic miles for the USSR's Bratcsk Reservoir.
