I don't know, Mick. While the delta is fairly big, it's not huge -- and there's a lot of debris strewn along it. Most of the delta has been shaped by the river in such a way that there are very few flat locations and it's rather hit and miss at the best of times for tent spots. Probably not much in the trees either as it's really dense there.The river will and has wandered over time, but theres such a huge flat delta down there, that there's got to be something to be found in amongst the trees IF the 2 typical sites are not usable. It does look like even the south site has various options.
Nothing of any type of traditional campsite that is kayak or canoe accessible but if you needed to, you could set up a tent for the night at the end of the road.What's available at the top of the lake?
