Nigeria is one of the Africa countries known to have a lot of tourist centres. One could now be inquisitive to ask if dams are one of such and if yes, where are they situated. Hence, this post tends to examine ‘All Dams in Nigeria and their locations.
A dam is a structure built across a river or stream to hold backwater. People have used different materials to build dams over the centuries. Dams are built to provide water for human consumption, for irrigating arid and semiarid lands, or for use in industrial processes.
They are used to increase the amount of water available for generating hydroelectric power, to reduce peak discharge of floodwater created by large storms or heavy snowmelt, or to increase the depth of water in a river in order to improve navigation and allow barges and ships to travel more easily. Dams can also provide a lake for recreational activities such as swimming, boating, and fishing.
Feature of Dams
A typical dam consists of the heel, toe, freeboard, spillway, galleries, sluiceway, abutment and diversion tunnels.
Heel: contact point with the ground on the upstream side (reservoir side).
Toe: contact point with the ground on the downstream side.
Freeboard: The vertical distance between the reservoir water surface and the top of the dam.
Spillway: A drainage pipe that could discharge excess water from the reservoir to prevent overflowing of the dam.
Galleries: Rooms constructed for regular checks and repair operations. They are located within the dam.
Sluice way: A channel with gates to let rubbish, excess soil or mudflow out from the reservoir. This feature could also reduce the pressure on the dam. This feature locates at the ground level of the dam.
Abutment: the sides of the hills or valley where the whole dam structure rests on.
Diversion tunnels: These features are constructed before the construction of the dam. They help to divide the river stream and keep the river bed dry in order to provide a working space for the dam.
Depending on the location and also the use of the dam, characteristics of the dam could vary and a few extra features could be added to provide services.

Conclusion: All Dams in Nigeria And Their Locations
Conclusively, you should note that there is a slight difference between reservoirs and dams. A reservoir is a lake that is created by a dam artificially while a lake is formed naturally without the need for a dam. With this, we have several other dams which are not all that popular.
