The Dadin-Kowa Dam is located 5km north of Dadin-Kowa village (about 37km from Gombe town along Gombe-Biu Road) in Yamaltu /Deba Local Government Area of Gombe State on Gongola River.

The Dam project was initially identified for hydro-electric power generation in 1957 by the Niger Dams Authority. However, in 1976, the Upper Benue River Basin Development Authority commissioned Shawmont Montreal engineering development corporation of Canada to review and upgrade the previous studies for contruction of a multipurpose Dam.

In 2005, the federal government approved completion of the hydropower component through concession agreement between the authority and MS MABON energy Nigeria limited. As at April 2017, the concessioneer has completed the power component by 80% and expected to be commissioned by the end of 2019.

The world bank has commissioned detail studies and design of 3000ha irrigation scheme at Dadin Kowa phase I. Procurement process for the construction contract is expected to be completed by first quarter of 2019.
