Clanwilliam Dam is a concrete gravity dam on the Olifants River, near Clanwilliam, Western Cape, South Africa. It was established in 1935, and the wall was raised to its current height of 43 metres (141 ft) in 1964.[1] The main purpose of the dam is to provide irrigation water to the agricultural region downstream. It has a capacity of 121,800,000 cubic metres (4.30×109 cu ft).[2]

The feasibility of raising the dam wall by another 15 metres has been investigated.

In 2015 an infrastructure development company has been appointed to do the supervision and contracts management of the project to raise the dam level. As of August 2015 the dam is planned to be raised by 13 meters, increasing its capacity by 70 million cubic metres of water.[3]
