Qedusizi Dam

Qedusizi Dam, previously known as the Mt Pleasant Dam, is a composite type dam with a roller-compacted concrete (RCC) or 'rollcrete' spillway and earth-fill embankments. It is located on the Klip River in KwaZulu-Natal, South Africa upstream of the town of Ladysmith. Site preparation began in 1994, was completed in 1997 and serves mainly as a flood attenuation and control dam to reduce flooding in the town of Ladysmith. The town is located in a loop of the Klip River and was established there primarily for defense reasons in 1847 by Boers before being annexed by the British. It has experienced numerous floods ever since.
