Lake Nangbéto is a large artificial reservoir on the Mono River, situated on the border between Togo and Benin, created in 1987 with the construction of the Nangbéto Dam. Covering an area of approximately 180 square kilometers, it is one of the most significant bodies of water in the region and primarily serves to generate hydroelectric power for both countries. Beyond energy production, the lake has transformed the local economy by promoting fishing and irrigated agriculture in the surrounding areas. The lake's ecosystem hosts a growing population of hippopotami and numerous waterbird species that use the lake as a resting site. The shorelines are partially forested, providing habitat for reptiles and small mammals. Historically, the construction of the dam was a milestone of binational cooperation within the framework of the Communauté Electrique du Bénin (CEB). Today, however, the lake faces challenges such as sedimentation and fluctuations in water levels due to climate change. Lake Nangbéto is not only a technical structure but also an important ecological factor influencing the microclimate of the Centrale and Plateaux regions.
