I’d agree with Denis’s assertion re Wollogorang (Creek) is at the headwaters of the Lachlan tributaries (except for the drinks bit
J), But it also looks like the Wollogorang Lagoon itself might be a contained blind drainage system
(I’ve never visited it so am going only on Google maps satellite view.
But I’d always thought Rose Lagoon was also a contained small internal drainage system. A quick look at Google Maps shows a couple of small creeks of only a
km or so in length draining from the SE into the southern end of Rose Lagoon, but as far as I’ve been able to see there is no outlet from the lagoon, which butts up against the highway. All dams on the northern side of the highway at that point indicate a
southerly drainage from the higher slopes/hills, i.e. towards Rose Lagoon, whether they actually make it to that body of water or not these days.
Willow Tree Creek, just a couple of km to the west of Rose Lagoon, does flow north-west to join Collector Creek several km north of Collector, and then presumably
south, through Collector, into the northern end of Lake George.
So it seems to me that Rose lagoon is just one of a few dimples in the flattish high country at that part of the Great Dividing Range.

Hi Geoffrey and others
I am pretty sure that Wollogorang is the very top ( southern) end of the Lachlan River system, which of course, ultimately drinks west, into the Murray Darling system.

Thanks Harv. We have also visited the below issues before, but I just had a quick refresh on Google
Earth.
You will know that the nominal continental divide is marked on the Federal Highway between Canberra
and Goulburn. On the western side of the Federal Highway is ‘Wollogorang’ with its own reedy lagoon, and a bird site to which Malcolm Fife led excursions in the early 1990s. I used to think Rose Lagoon was part of an ephemeral watercourse marked by a sign
that ran south from Wollogorang towards Lake George. However according to Google Earth Rose Lagoon is at 750m, while the northern end of Wollogorang is at 710m, possibly draining towards the Hume/Federal junction (about 685m). So while Rose could be part
of the Lake George drainage (unlikely from what I remember of the southern end of Rose) it could be fed by a contained drainage system or it could be an upper part of the same system as Wollogorang which probably drains towards Goulburn (ie part of the Pacific
drainage) although it is also very close to the headwaters of the Lachlan. Any hydrographers about?
I also use Rose Lagoon.
The official gazetted name is Rose Lagoon – see
http://www.ga.gov.au/place-names/index.xhtml# and extract below.
My understanding is that the adjacent property and veterinary practice is named Rowes Lagoon, perhaps
as a play on words, perhaps with legitimate historical links, I don’t know.
(sorry for revisiting this , Geoff)

I use ‘Rose’. There is evidence in support, and quite a long exchange in the archive. Let’s not
revisit

Can COG members therefore confirm that the ‘Rose Lagoon’ that appears in back issues of Canberra Bird Notes is probably a misnomer and should have been ‘Rowse? If not, there are
obviously two different lagoons, or a ‘lagoon by another name’!
