Water from the Orange River at Vanderkloof Dam is fed into the Riet River at Jacobsdal to provide water for irrigation. This has the combined effect of adding water to the river and lowering the salinity. When Vanderkloof Dam is spilling excess water from Vanderkloof Dam is transferred to the Kalkfontein Dam.

Theewaterskloof dam has a capacity of 480,406 megalitres (16,965.4 × 10 ^ 6 cu ft) of water, and when full the reservoir covers an area of 5,059 hectares (12,500 acres). [2] The catchment area of 500 square kilometres (190 sq mi) is served by streams emanating in the Hottentots Holland mountain range.
Kalkfontein Dam reservoir is often quite low (10-20% full) as the upstream area is hot and dry and too small to fill a dam of this size, however during flooding on the Orange River, water is transferred from the Orange River at Vanderkloof Dam to Kalkfontein Dam. In 2021 this led to the reservoir rising from 17.3% to 61.7% in a single week.
