Floods and Dams
On Kangaroo Island, we have just been through a record breakingly wet Winter.
There have been floods on the mainland too, but water restrictions are still in place in capital cities.
The excuse for not building new dams has been that it isn’t going to rain any more. But then why have state governments been subsidising the installation of rainwater tanks at private homes?
‘Solutions’ like desalination plants are being built around Australia. But these massively expensive by comparison with dams, use large amounts of energy, require high levels of maintenance, and are untested over the long term.
There has been no overall reduction in rainfall on the Australian continent over the last century, so why are we still being given the ‘no point, no rain’ excuse?
Australia is a country of extremes. Long droughts followed by massive floods. Overall, there is plenty of water for everyone.
The problem is not that there is not enough water, but that there is not enough water storage.
The more water storage we build, the better we will be able to cope with the perfectly predictable dry periods, and the less damage will be done by floods (because more of the water will be captured).
Even if rainfall was reducing, this would be a reason to build more dams, not less.
