Wivenhoe Dam

Wivenhoe Dam is a rock and earth-fill embankment dam with a concrete spillway across the Brisbane River in South East Queensland, Australia. The dam takes it names from the local Wivenhoe Pocket rural community. The dam wall is located about 80 kilometres (50 mi) by road from the centre of Brisbane. The primary purpose of the dam is the supply of potable water for the Brisbane and Ipswich regions. South-east Queensland's largest dam also provides for flood mitigation control, hydroelectricity, and recreation. The impounded reservoir is called Lake Wivenhoe and the dam, the lake and a narrow strip of surrounding land forms a locality also called Lake Wivenhoe. Wivenhoe Dam was planned in the early 1970s. The 1974 Brisbane flood highlighted the need for flood protection for South East Queensland. The lake also forms part of the water storages for the Wivenhoe Power Station.
