Lake Ginninderra is a reservoir formed by the Ginninderra Dam, an earth-filled embankment dam across Ginninderra Creek, located adjacent to the Belconnen Town Centre, in Canberra, in the Australian Capital Territory.
Overview
The National Capital Development Commission announced news of the dam in 1972.[1] The dam was constructed in 1974 to collect stormwater discharge from a 98.8-square-kilometre (38.1 sq mi) catchment area that includes the surrounding suburbs of Aranda, Macquarie, Cook, Bruce, Belconnen, McKellar, Giralang, Kaleen in the eastern areas of Belconnen.
The dam's earthen wall is 17 metres (56 ft) high and 365 metres (1,198 ft) long. The embankment was formed through the construction of Ginninderra Drive and the resultant reservoir has a maximum capacity of 3,700 megalitres (3,000 acre⋅ft) when full, covering a surface area of 105 hectares (260 acres) and an average depth of 3.5 metres (11 ft). Water flow out of the lake is via a multi-celled concrete culvert structure and uncontrolled spillway chute on the Ginninderra Drive embankment that can handles flow of 965 cubic metres per second (34,100 cu ft/s).[2]
During 2004 the Ginninderra Drive embankment was raised by one metre (three point three feet). The earthen embankments on the Coulter Drive side of the lake were raised as well.
The lake is home to wildlife, including Black swans, moorhens, ducks and the Rakali.
The Belconnen Arts Centre and the Lake Ginninderra Sea Scouts are located on the southern shore of the lake.[3]
