As a follow-up to my post about the Abbott/Joyce call for more dams.
The Wivenhoe dam above Brisbane was built for the purpose of mitigating flood waters - that's why they talk about it being at 189% of "capacity" as it is designed to only temporarily house excessive water.
The LNP proposed that the dam level be increased earlier this year - that is reduce its capacity to hold the sudden inflows that otherwise become flood waters.
Yes you can build dams as flood mitigation - sometimes. But you can't build dams as flood mitigation but keep them full to use for agriculture.
