Lake GinninderraLake Ginninderra is an artificial lake located on the Ginninderra Creek in Canberra. It is adjacent to the Belconnen Town Centre. The lake was constructed in 1974 to collect stormwater discharge from a 98.8 km² catchment that includes the surrouding suburbs of Aranda, Macquarie, Cook, Bruce, Belconnen, McKellar, Giralang, Kaleen in the eastern areas of Belconnen and Gungahlin. The lake was formed through the construction of the Ginninderra Drive embankment across Ginninderra Ck. Creating a lake with a surface area of 1.05 km² and an average depth of 3.5 metres. water flow out of the lake is via a multi-celled concrete culvert structure and spillway chute on the Ginninderra Drive embankment. During 2004 the Ginninderra Drive embankment is being raised by one metre to make sure it meets current standards for a once in a million year flood. Also the earthen embankments on the coulter drive side of the lake have been raised as well. The necessity of these elevations is questionable largely due to the fact that Ginninderra Drive is nearly 8 metres above the level of the lake, and even during the heaviest of rainstorms in the last 25 years the lake has never risen by more than 300mm References Ginninderra
