Yerrabi Pond I suspect is fairly deep as there are usually over 20-30 Hoary-headed Grebes present at the far northern end. I walk or cycle around the lake regularly as I live nearby in Ngunnawal.
Large groups of Hardhead are common in winter as well as the odd Australasian Shoveler and even Pink-eared Duck on rare occasions.
Did you by any chance see the resident Musk Duck(s)?
I think most of Lake Ginninderra may be too deep for Hardhead and Hoary-headed Grebe. Not sure.
The small piece of water you refer to near the roundabout off Wm Sim Drive I believe is part of the McKellar Wetlands. My understanding is that a local landcare group has created these wetlands to conserve the local frog population - there is another pond with a dense reedbed near the William Webb Drive-Owen Dixon Drive intersection with an explanatory sign on frog species.
I also visit this wetland regularly to keep an eye out for crakes...before they finish developing all the new houses nearby.
I walked around Yerabbi Ponds on the Thursday and estimated upwards of 60 Hardheads (or White-eyed Duck ) present.
They were also present in numbers on what my Gregory's labels Gungahlin Pond.
On a small piece of water south west of the Baldwin Drive, Sir William Slim roundabout
there were two adult birds and two immatures.
Today when i walked around Lake Ginninderra I saw no Hardheads; not very many ducks at all really, but no Hardheads.
Is there an obvious reason for this ?.
There are also large numbers of Grebe (mostly Australasian, but some Hoary-Headed) on Yerrabi Pond.
I would guess 40 but i wasn't keeping track of them.
Is Yerrabi Pond deep? clear?
Would this be a mallard/black duck cross?
There is a white ring around its neck not obvious in the photo.
