On 11 January 2011, Wivenhoe Dam reached its highest level ever, 191% of normal water supply storage capacity, as it held back floodwater. [16] Because it is an embankment dam, it was not designed to spill over its crest or overtop and there is a risk that if waters spilled over the crest, this could erode the dam wall and potentially cause the ...
Seven metres was added to the height of the dam wall for flood mitigation in the same year. [5] It was decommissioned in 2003, then in early 2006 water from Enoggera Dam was again added to inner north-west Brisbane's drinking water supply, when drought had reduced South East Queensland's water supply to critical levels.
The North Pine Dam was designed with little flood mitigation capacity in mind, being designed only for water storage. As such, during flood seasons the location of the dam spillway causes the flooding and closure of Youngs Crossing Road. [3] Flood conditions last affected the dam catchment in October 2010, and prior to that 1991, 1989 and 2000 ...
Tasmania's Gordon Dam, one of the largest in Australia, was constructed in the 1970s. It has a catchment area of 1,280 km2 (494 sq mi). It has a catchment area of 1,280 km2 (494 sq mi). Dams and reservoirs in Australia is a link page for any dam or reservoir in Australia.
Lake Manchester Dam is a concrete gravity dam with an un-gated spillway across Cabbage Tree Creek. It is also known as Cabbage Tree Creek Dam. [4] It is in the locality of Lake Manchester, City of Brisbane, Queensland, Australia. [5] The main purpose of the dam is for potable water supply of Brisbane. [1] [3] The impounded reservoir is called ...
Brisbane combined Dam levels. Brisbane water levels reduced to under 20% of capacity, having had no substantial inflow for five years. [49] Brisbane organised to be supplied via larger dams, a pipeline and possibly also recycling. The Gold Coast Desalination Plant was constructed at Bilinga, delivering water from 2009. [50]
Falling dam levels prompted Sydney Water to impose Level 1 water restrictions on the Sydney area from 1 October 2003. [15] When these restrictions failed to stem the reduction in the city's water supplies as a result of continuing drought, and with dam levels dropping below 50 per cent, Level 2 water restrictions were introduced from 1 June 2004.
Wivenhoe Dam is primarily designed for drinking water supply to Brisbane, Ipswich, and surrounding areas, as well as flood protection for Brisbane. The 2022 floods would have been significantly worse if it were not for Wivenhoe Dam, with the dam also being ~56% full prior to the huge inflow. [31]
