The 19.2MW Liouesso dam on the Lengoué River is expected to be completed in June 2016. President Denis Sassou Nguesso visited the construction site on 13 May and told reporters he was satisfied with progress on the project, for which he laid the foundation stone in May 2012.

The dam is 84km from the city of Ouesso, in the northern Sangha region, and will supply Ouesso, Pokola, Ngombé, Mokeko and Ngbala.
