The Nangbeto Dam is an embankment dam on the Mono River in the Plateaux Region of Togo. It was constructed between 1984 and 1987 for the purpose of providing hydroelectric power to both Togo and Benin as well as creating fisheries and supplying water for irrigation. The dam's 65.6 megawatts (88,000 hp) power station was commissioned in June 1987. The project was financed by the World Bank and African Development Bank at a cost of US$98.22 million.
