I thought this was interesting. A report dated 1919 but referencing the discovery of Lake George near Canberra in the previous century. It gives a bit of an indication of the water level during the 19th century from the time it was discovered. For those that don't know about this large lake it has a reputation for drying out for long periods of years only to fill seemingly overnight at its own whim...
The lake has a bit of mystery to it. I can remember my parents telling me some cadets from Duntroon went missing whilst rowing during what must have been the 1950's and of course there is the urban myth that another lake in China or New Zealand empties and fills in sync...
