Pongolapoort Dam, commonly referred to as Jozini Dam creating Lake Jozini, is an arch type dam (double-curvature single-arch[1]) in northern KwaZulu-Natal, South Africa located on the Phongolo River. The dam is situated just north of the settlement of Jozini, 280 km north-east of the port city of Durban. The dam was constructed in 1973 at the eastern end of the narrow gorge separating the Lebombo and Ubombo ranges. The dam mainly serves for irrigation purposes and its hazard potential has been ranked high (3). The Phongolo River is the dam's largest feeder and outlet as well as the dam's only perennial feeder.
