Amazing Lake George pulls another reappearing trick

Lake George about 40km from Canberra is making another amazing recovery. When full, the lakes waters spread over 155 sq. km. The lake 25-kilometre long and 10-kilometre wide has the ability to refill in a spectacular, mysterious fashion beside the Canberra to Sydney road.

In 2001 Lake George, New South Wales was bone cracking dry and hotter than a snakes belly in a wagon rut in the summer sun. NSW and the ACT were parched by a drought the like of which had not been seen in 50 years.

It is said that Lake George has hidden secrets. It is perhaps connected by aquifers to the Yass River. The lake's constantly shifting water level, as well as its proximity to significant research organisations in nearby Canberra have made Lake George one of the most studied lakes in Australia.

The NSW Department of Primary Industries Office of Water reports that the natural drainage basin is fed by 10 major tributaries that drain from the surrounding hilly country. These tributaries originally drained to the Yass River before they were cut off by the uplift of the Lake George Range.

The northern part of the catchment is drained by Collector Creek, Tarago Creek and Currawang Creek, while the southern end of the catchment is drained by Butmaroo Creek and Turallo Creek. Insidewater.com.au reports that one of the worlds oldest lakes, Lake George formed when the natural outlet of the valley was dammed by geological uplift, five million years ago, making it a closed body of water. It is one of the saltiest water bodies in inland NSW when flooded.

On the shores of Lake George is a 140 megawatt wind farm electricity from which powers the new Kurnell desalination plant in Sydney. Lake George has supported 201 species of birds, 31 mammal species, 29 species of reptiles and 12 amphibian species.
