The Biggera Creek Dam, or formally the Biggera Creek Flood Mitigation Dam, is a dam established for flood mitigation purposes over the Biggera Creek, located in the South East region of Queensland, Australia. The dam is situated approximately 3 kilometres (1.9 mi) northwest of Southport in the suburb of Arundel. It is operated by the Gold Coast City Council.
The dam has a capacity of 3,700 megalitres (810×10^6 imp gal; 980×10^6 US gal) and the height of the dam wall is 12.5 meters (41 feet).[1]
Because its sole purpose is flood mitigation, the retention basin behind the dam is almost always empty of water.
