Completed in 1981, it was originally envisaged to become part of the Eastern National Water Carrier, a scheme to supply water to Namibia's capital Windhoek from the Okavango River, 1,000 kilometres (620 mi) to the north on the Angolan border.[3] The scheme was never completed. Omatako Dam today only contains floods and supplies water to the Von Bach Dam.[2][4] As such, it is one of three dams supplying the capital Windhoek with water.[5]
