It was established in 1935, and the wall was raised to its current height of 43 metres in 1964. The main purpose of the dam is to provide irrigation water to the agricultural region downstream. It currently has a capacity of 121,800,000 cubic metres. At present [2025] the wall is being raised by 13m to increase capacity. The project completion date has been extended to ~2030 and costs have escalated. (Wikipedia accessed May 2017. See also pamphlets at Heritage Western Cape). |
