Capital Projects being Executed by the Department:
Nigeria has about 264 dams with a combined storage capacity of 33 BCM of water for multipurpose use that includes Water Supply, Irrigation, Hydropower, fisheries, eco-tourism etc., of which 210 are owned by the Federal Government, 34 by the States and 20 by private organizations.
These dams have about 350,000 hectares of irrigable land around the vicinities ready for development.
There are also 27 ongoing small earth dams nationwide with a total potential irrigable land of 2,700 hectares.
Currently, the Department is engaged in the construction and rehabilitation of 33 dam projects and 27 Small Earth dams. Seven other major dams with a combined storage capacity of 2,269 million cubic meters have been completed. These are Gurara, Owiwi, Sabke, Owena, and Shagari dams as well as the rehabilitation of Goronyo and Alau dams. Owiwi multipurpose dam was commissioned by Mr. President in 2010. Rehabilitation works on Goronyo Dam have commenced on the emergency spillway, which was breached as a result of 2010 flooding.
In line with the policy directive of government to increase energy supply to meet the nation’s energy demands, The Ministry is collaborating with the Federal Ministry of Power on the aspect of handling the area of power generation component, while the Ministry handles the aspect of civil works in all the dam projects with hydropower potentials. Small hydropower schemes have been integrated into some dam projects across the country in order to increase the energy supply of the nation.
To date, the Department has identified and carried out studies on some of the completed and on-going dam projects for hydropower, nineteen (19) of which have the potentials for hydropower generation with a total capacity of 3,557 MW. These dam include; Gurara, Oyan, Ikere Gorge, Bakolori, Dadin Kowa, Tiga, Kiri, Jibiya, Challawa Gorge, Owena, Doma, Waya, Mgowo, Zobe, Kampe, Kashimbilla, Ogwashiku, Zungeru and Mambilla.
