Aging & filling of Lake Tuggeranong

["Philip Veerman" <>]

I agree with Jack's observations. However I wouldn't think the issue relates to "aging". As I recall it (and I too went there often) the whole area was variably swampy. As the lake was created and water levels rose, many swamp birds that previously were hard to find, were forced to the edges. I particularly recall a metal grid about a metre over the water and extending in from the edge, on which one could stand, at what is now the opposite side of the lake from the shops, where several Baillon's & Spotted Crakes could be seen at very close range, (virtually looking down at them). What happened was that large areas of swampy ground were replaced by a much simpler system of deep water with steep edges leading to short lawns. I think that the loss of variety of habitat, rather than the time factor is the issue.

 

My comments are not likely to be relevant to the issue with Musk Ducks. I don't think lake aging is relevant to the Musk Ducks either. They live on old lakes elsewhere so there are other factors involved (don't ask me!).
