Constant Checks Necessary to Maintain Integrity of Kariba Dam Wall

Lake Kariba is one of the world largest artificial lakes.  The wall that holds the water in the resevoir was built between 1955 and 1959. Since then it has remained a work in progress. Each working day a team of experts checks the integrity of the dam wall to ensure it does not collapse under the weight of the water it holds back.
