[edit] Lake George

I'm not aware of any scientific research that suggests water can drain from Lake George into the Yass River. No water draining cracks appear on the surface of Lake George and sediment coring has revealed there are 30 meters of sediment below the current bed surface of Lake George, which have been deposited over the lakes long existence.

Lake George is a long shallow with a very small catchment; resultant evaporation rates and an ability for the wind to blow the water back on itself fully explains its mysterious filling and drying episodes on both the short term (hours) and long term (years) time scales.

The average depth of the lake even when quite full is certainly not 8 metres. It is very shallow, in most spots no more than 1 metre. This I know, because I have waded the lake when fishing it in the very early 90s when it was quite full.

[edit] Aboriginal massacre???

As a Canberra resident who has read a lot of history on the region I have not heard of an aboriginal massacre at Lake George. I feel I would have read about this massacre in the historical books, publications etc I've looked at over the years if it had much credence. I can only suggest that the existence of this massacre is doubtful. So I have removed this: "It is the site of a notorious massacre of an entire tribe of Aborigines in the nineteenth century." until somebody can find a credible reference/quote/extract to support it.

[edit] Formation of Lake George

Saw the online newspaper article on which the information on age and postulated link to outside aqufiers came from. I'm fairly certain there are inaccuracies in this article. In particular, I'm fairly certain that the Lake George escarpment that rose and formed the lake is far older than 27,000 years old. With 30 metres of accumulated sediment, the lake almost has to be older. Unfortunately I don't any ready access to authoritive references, but the 27,000 years old thing should be checked ASAP.

Reveals the lake is at least 140,000 years old, and I have have definitely read it is more than a million years old. Will modify the page accordingly. Codman 11:31, 26 September 2005 (UTC)
