The Gariep dam in South Africa
The Gariep dam is the largest dam of South Africa located on the Orange River, near the town of Norvalspont (Eastern Cape), 150 km south of Bloemfontein.
Its ground is geologically determined by deposits of the Beaufort group within the Karoo main basin.
The water is stored as drinking water for the city Johannesburg and the surrounding area. The dam has been built in order to prevent floods and for gaining electric energy.
