Nah can't say it has affected me at all really in the strictest personal sense.
My best mate from my childhood, 100m down the road from my childhood home - his family home completely under. Just surreal to see parts of the city that you know 4m, 5m under water.
The worst thing is, you can't help as the roads linking the city are flooded. Brisbane is a very hilly city in comparison to Melbourne, and you seem fine where you are but just a short walk away the roads will be under. The RSPCA were asking for volunteers to house pets and I would have loved to have helped, but Fairfield where they are is one of the worst hit suburbs.
Don't think you can hold the government accoutable for the dam situation, I think they would like to build more, but its hard to convince environmentalists. I also think that they could not have let much water go given that less than 5 years ago we had levels down below 20%. But the real thing is the amount of floodplains that the government has let development occur on under pressure from rising population and property developers. There are places that clearly shouldn't have houses on. Moreover, the newer style houses are largely concrete with no natural drainage. I must say it is oddly reassuring to pass a concrete house that is submerged and then see its neighbouring traditional Queenslander style house or cottage with its stilt legs, weatherboard and tin roof just above the water. Maybe our forebearers weren't so stupid after all.
