Australians love dams. Mostly because they see water as something only for human use, ignoring its complex role in the landscape. They also think they drought-proof places, which is about as smart as thinking you'd be richer if you had a bigger wallet. Dams can be useful, but nearly always they're destructive and cost a fortune to maintain. The only really long-term dams that do good are the ones created by beavers. I'd be all for releasing beavers into the Australian landscape.
