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 km northwest of Southport in the suburb of Arundel. It is operated by the Gold Coast City Council. The dam has a capacity of 3700 ML and the height of the dam wall is 12.5 meters (41 feet). Because its sole purpose is flood mitigation, the retention basin behind the dam is almost always empty of water.
