Wivenhoe Dam |
Four reports have been published into the operation of the Wivenhoe, Somerset and North Pine dams.
Water Supply Minister Mark McArdle says rainfall in January was the second largest on record since Wivenhoe was built.
He says legislation passed by the government before the floods hit helped operators make early decisions to reduce the levels of the Wivenhoe and North Pine dams.
Their capacity was dropped to 88 per cent two days before the floodwaters hit.
"Without this ability we may have had a different outcome for Brisbane, Ipswich, and the communities along the North Pine River," he said.
Mr McArdle says the reports are an important step to reassure people that the dams are managed well following the devastating floods two years ago.
