Kariba Gorge is a large, natural gorge through which flowed the Zambezi River on the border of Zambia and Zimbabwe, Africa. In 1959 the large double arch concrete Kariba Dam was completed, completely filling the gorge and creating the largest man-made lake in the world.[1] Lake Kariba was filled between 1958 and 1963 following the completion of the Kariba Dam at its northeastern end, flooding the Kariba Gorge on the Zambezi River and displacing large numbers of wildlife and the local Tonga people.
