The Katse Dam, a concrete arch dam on the Malibamat'so River in Lesotho, is Africa's second largest dam. (The Tekeze Dam, completed in early 2009, is now Africa's largest double curvature dam). The dam is part of the Lesotho Highlands Water Project, which will eventually include five large dams in remote rural areas.
The dam was built by a consortium of Bouygues, Concor, Group 5, Hochtief, Impregilo, Kier Group and Sterling International. The dam was completed in 1996 and the reservoir filled with water by 1997.
