Good morning Mike,
I just heard your conversation with Ross Knee, ACTEW's principal strategic planner, about environmental flows.
I can understand his point about the need for environmental flows to keep our rivers healthy, but he said that Googong Dam's environmental flow goes in to the Molongolo River and becomes Lake Burley Griffin. Googong is our largest dam by a very large margin, somehow I don't think anybody would mind if the flow in to the lake was reduced in an effort to help fill Googong. In addition, if the lake was to be mostly drained then we could send a lot of water down to Burrinjuck Dam, or with a bit of piping and pumping send it to Corin Dam which is only 16.3% full.
I don't think people would mind if Lake Burley Griffin was to be temporarily turned back in to a river to prop up our dams. It would look a bit odd, but it's only an ornament.
