Constructed during 1965/66 to secure a 30 million gallon per day water supply to a rapidly developing copper and phosphate mining complex, the Phalaborwa barrage spans the Olifants river near the Kruger National Park boundary. Comprising a 770-ft long concrete structure in the river section with long rolled earthfill embankments on the flanks, the barrage stores 3,800 morgen ft. of water in an eight mile long reach of the river. The concrete section incorporates 22 radial gates, each 30 ft. wide by 28 ft. high. Salient features of the design, the model studies, the construction programme and the routine for operation of the barrage are descriptionbed.
