AussieDan 6:51:
No, Aussie, I’m not suggesting permanently storing excess water. The plans I read about many years ago were about building a system whereby water could be diverted around, through or under the mountains to the ususally dry western side of the dividing range for irrigation purposes, as well as taking the occasional excess. I haven’t the faintest idea whether they’re feasible or not, but I believe they were seriously considered at the time. (1940’s)
Mind you, I should think that any massive engineering scheme like that would upset the enviro’s as there is bound to be a rare centipede that might be drowned, so that’s another good reason to consider it. Best wishes, Dave.

Nothing the climate does will change big government’s, along with their nodding dupes, grab for power. Alarmism is the fuel and the present “climate change” just the vehicle their using at the moment. If the climate thing doesn’t work out then on to something else and the mainstream media will promote that 24/7-there’s no end to it because lust for power/control was there in the beginning and will be there when the last human takes his/her last breath-probably on a frozen planet.
