There were a number of factors that contributed to the origin of the Brisbane flood. Ultimately, it could be said that the Brisbane flood started at Wivenhoe Dam, largely as a result of a torrent that started further west.
On 10 January 2011, Toowoomba, a city which sits at an elevation of 700m at the top of the Great Dividing Range, received 150 mm of rain within a 40 minute period. The ground could not hold any more water, and the waters from the escarpment at the top of the range filled the quarry and rushed down the range. This wall of water rushed through Lockyer Valley to the catchment areas of the main dam that protects the city of Brisbane from flooding, sending its capacity to 190%. The gates had to be opened, sending the equivalent of two Sydney Harbour's worth of water into the Brisbane River each day. It was this release of massive volumes of water in a short period of time which started the flood in Brisbane.
