Hadejia River

The Hadejia River (known as "kogin Haɗeja" in Hausa language) is a river in northern Nigeria and is a part of the Yobe River (Komadugu Yobe). 
The river flows through Hadejia and Nguru. 
Water from the river has been held back in a process called damming for the purposes of irrigation. This has reduced the amount of water in the Hadejia-Nguru wetlands, which the river forms along with Nguru Lake. 
The Hadejia river is now 80% controlled by the Tiga and Challawa Gorge dams in Kano State.
