- Capacity: 11 billion cubic meters
Zungeru Dam is a major hydroelectric project under construction on the Kaduna River. Once completed, the dam will generate 700 MW of electricity, making it one of Nigeria’s largest power-generating dams. The dam will also provide water for irrigation, reduce flooding, and support the agricultural development of the region.
5. Oyan Dam
- Location: Ogun State
- River: Oyan River
- Power Output: None
- Capacity: 270 million cubic meters
Oyan Dam, located on the Oyan River, supplies water for domestic and industrial use to Lagos and Ogun States. The dam is also used for irrigation and supports local agriculture by providing a reliable water source. Although it does not generate hydroelectric power, Oyan Dam plays a critical role in water management and flood control in southwestern Nigeria.
6. Tiga Dam
- Location: Kano State
- River: Hadejia River
- Power Output: None
- Capacity: 1.9 billion cubic meters
Tiga Dam, built on the Hadejia River, is a large reservoir used primarily for irrigation. The dam supplies water to the Kano River Irrigation Project, which supports agriculture in the region. Tiga Dam also helps manage water flow in the Hadejia-Jama’are River Basin, reducing the risk of flooding and providing water for domestic use.
7. Kiri Dam
- Location: Adamawa State
- River: Gongola River
- Power Output: None
- Capacity: 615 million cubic meters
Kiri Dam, located on the Gongola River, provides water for irrigation, supporting agriculture in Adamawa and surrounding areas. The dam plays a key role in regional agricultural development by supplying water to the Savannah Sugar Company and other farms. It also helps control flooding in the Gongola River Basin.
8. Bakolori Dam
- Location: Zamfara State
- River: Sokoto River
- Power Output: None
- Capacity: 450 million cubic meters
Bakolori Dam, built on the Sokoto River, serves primarily for irrigation purposes. It supports the Bakolori Irrigation Project, which provides water for rice, wheat, and other crops. The dam also helps regulate water flow in the Sokoto River, reducing the risk of floods and ensuring a reliable water supply for local farmers.
9. Challawa Gorge Dam
- Location: Kano State
- River: Challawa River
- Power Output: None
- Capacity: 904 million cubic meters
Challawa Gorge Dam, located on the Challawa River, supplies water for irrigation and domestic use in Kano State. The dam supports the Kano River Irrigation Project and provides a consistent water supply for agricultural activities. It also helps regulate water flow, reducing the risk of flooding in the region.
10. Dadin Kowa Dam
- Location: Gombe State
- River: Gongola River
- Power Output: 40 megawatts (MW)
- Capacity: 2.8 billion cubic meters
Dadin Kowa Dam is located on the Gongola River and serves multiple purposes, including irrigation, water supply, and hydroelectric power generation. The dam generates 40 MW of electricity and provides water for irrigation, supporting agriculture in Gombe State. Dadin Kowa Dam also helps reduce flooding in the Gongola River Basin.
Conclusion
Nigeria’s dams play a critical role in the country’s development by providing electricity, water for irrigation, and flood control. Major dams like Kainji, Jebba, and Shiroro contribute significantly to Nigeria’s hydroelectric power supply, while others like Oyan, Tiga, and Bakolori support agriculture through irrigation. These dams are essential for ensuring water security, supporting agriculture, and driving economic growth. As Nigeria continues to invest in new dam projects, such as Zungeru, the country’s capacity to generate power and manage water resources will continue to grow.
