A hydroelectric dam is essentially a mechanical gateway that can control how often, how much, and how fast the water is allowed to passed through. Water above the dam is collected and stored into a reservoir.
The hydroelectric power produced by the dam was supposed to provide a reliable source of energy for large industries as well as export power to Togo and Benin, but in the early 1980's and early 1990's, very low water levels due to drought brought a halt to energy exports and interrupted industrial production.
