Mohale Dam
The 43rd tallest dam in the world
Mohale Dam is a concrete faced rock-fill dam in Lesotho. It is the second dam, under Phase 1B of the series of dams of the proposed Lesotho Highlands Water Project (LHWP), which will eventually include five large dams in remote rural areas of Lesotho and South Africa. The project has been built at a cost of US$1.5 billion. The Mohale Dam was awarded the 2005 Fulton Awards by the Concrete Society of South Africa as having the "Best Construction Engineering Project and Best Construction Technique."
