The Bakolori Dam is in Sokoto State in northwest Nigeria. It was completed in 1978 and its reservoir filled by 1981. It is a major reservoir on the Sokoto River, a tributary of the Rima River, which in turn feeds the Niger River. Water from the dam supplies the Bakolori Irrigation Project.
The dam has a capacity of 450 million cubic meters, with a reservoir covering 8,000 hectares extending 19 km (12 mi) upstream.
Dam construction displaced many peasant farmers without providing alternative land or financial compensation. Many people died in protests over their loss of livelihood. The project has become known as a classic example of development failure.
