Rockview and Kogelberg Dams

Rockview Dam is the upper storage unit of the Palmist Pumped Storage Scheme and its full supply level is at RL 531 m, i.e. 285 m above that of Kogelberg Dam. The dam basin consists of two natural depressions, with the larger one located on the southern side. The two depressions are linked by an excavated channel (Fig 1). The main embankment, which is approximately 1 300 m long and has a maximum height of 48 m, has been constructed along mainly the southern perimeter of the basin. The secondary embankment, which is about 670 m in length and has a maximum height of 33 m, forms the northern perimeter of the dam basin. The natural topography borders the remainder of the basin.
