The Clyde Dam
"Clyde Dam is the largest concrete gravity dam in New Zealand consisting of one million cubic metres of concrete.
It's height is 100 metres, width at base is 70 metres, width at crest 10 metres and length at crest 490 metres.
Controversy surrounded the building of the dam, which saw a number of orchards and houses removed from the Cromwell Gorge to allow the flooding of the river valley. The lake formed by the dam, Lake Dunstan, is 26.4 square kilometres in size. Its recreational uses include water-skiing, boating, canoeing, jet boating, boat cruises and eco-tours of the abundant fish and bird life."
