Below are the reservoirs (artificial lakes) in the world with a surface area exceeding 500 km 2 (190 sq mi). Reservoirs can be formed conventionally, by damming the outlet of a canyon or valley to form a lake; the largest of this type is Ghana's Lake Volta, with a water surface of 8,500 km 2 (3,300 sq mi).
For example, a small dam, two hydroelectric plants, and locks on the outlet of Lake Superior make it possible to artificially control the lake level. Certainly, the great majority of the lake is natural. However, the control of water that can be held in reserve means a portion of the vast lake functions as a reservoir.
