The flood you refer to weren't all that big. The 1974 flood were bigger. And if yer have a look-see at the water level markings on the side of the Brisbane polo club building the 1974 flood is dwarfed by the floods of the late 1800's.
And re the dam: When the Wivenhoe dam were built the engineers allowed for expected major floods with a 'buffer' maximum allowable water level well below the dams actual maximum capacity. The buffer were exceeded before the floods because the then government were led to believe by the global warming looneys (BoM etc) that due to global warming there would be no more big floods..
