Four major floods have occurred in Brisbane.
The first was on 14 January 1841. To date, these floods have been the worst, high-level wise, although there was less destruction to property as the town was still very young and undeveloped. Flood levels were reported to be over 8 metres above the mean sea level.
The next major flood began on 5 February 1893. These floods came within 7cm of the 1841 levels.
The worst floods in terms of death and loss of property occurred in January 1974 when tropical Cyclone Wanda developed into a rain depression that dumped hundreds of millimetres of rain on an already saturated southeast Queensland. Since the construction of Wivenhoe Dam on the Brisbane River within a few years of this flood, Brisbane was believed to be flood-proof.
This changed when, on 11 January 2011, the Brisbane River again broke its banks. The flood was the result of a La Ninaweather pattern, together with the state being saturated by the rainfall resulting from a cyclone system that hit in the north on Christmas Day 2010.
Wivenhoe Dam, which was designed to prevent any further floods, exceeded 160% capacity, requiring the release of a massive amount of water, comparable to the volume of Sydney harbour.

The city of Brisbane was named after the Brisbane River, which John Oxley was directed to by some ticket-of-leave convicts who had found a good river. Oxley came into contact with these men who had become lost, and they showed him the river. Oxley named the river after Sir Thomas Brisbane, who was the Governor of New South Wales at the time when Brisbane was founded.
