FW: AOI catchments

[Con Boekel <>]

I have been following this conversation with a great deal of interest. I imagine that there is an unspoken caveat that the containment of contained catchments are subject to current rainfall patterns.

Thank you for resolving the watershed of the Lagoon with Many Names.  I am hoping to visit said quagmire with the COGWW group sometime soon(ish).

I am pleased you asked about the mighty Whiskers Creek.  Some 2 kms downstream of Chateau Champs de Beurre it submits its torrent to that of the Molonglo and thence, after passing sundry Water Treatment Plants, to the Murrumbidgee.

I cannot remember whether I have passed on my recent finding that Whiskers Creek is named after the person who originally surveyed the area, several of whose descendants still apparently reside in beautiful downtown Queanbeyan.

Returning to the matter of the Rose Lagoon catchment, it does seem that it and Wollogorang Lagoon  lie within a basin where the waters are locally contained, the main repository being Lake George although the smaller ones are independent of it, separated by divides of only a few metres height.  Wollogorang Creek passes by the lagoon of that name and meanders north of the Hume Highway, just failing to reach the depression that is the start of the Lachlan (olive shading).  Superimposing the approximate catchment boundaries on the AOI map gives quite a complex picture, surely one of the more interesting AOIs, hydrologically speaking, of any national capital.  No doubt others will know more detail.  For example Lake Bathurst is possibly self-contained, while the nearby ‘The Morass’ feeds into the Mulwaree/Wollondilly (violet shading), which used to reach the Hawkesbury before being contained by Warragamba Dam.  And to where does Whiskers Creek flow? The white area is the Murrumbidgee catchment. Between Canberra and Braidwood, the Kings Highway passes through 4 catchment areas.  Corrections happily received.
