Having driven past Lake George a couple times this month . It is quite full . Deepest in 30 years. The 4 foot cattle fences are underwater as well
.You could probably launch from the car expressway side of lake conveniently now...intead of eastern side..Don't know what wind is suitable .
I've heard of Canberra pole dancers doing it. It's a bit risky though, you want to know exactly where the fences as you don't wanna get snagged on rusty barbed wire.
EDIT: Here's an old thread with images of where the fences are:
Having driven past Lake George again last wednesday arvo coming home from snowys ,the lake is massive and the waters edge is close to dual carriageway ,appears easy launch from rest areas carpark on southbound highway depending on right wind direction ,whatever that is. Maybe a jetski supervision is warranted if guys go out... 15 years ago pommy John from kitepower Sydney organized a kiting landbuggy session there on dry lakebed. A few turned up and went out . Rob went out and said the ground lakebed was too boggy for the wheels that particular day.
This is a friends pic of lake...note how close water is to southbound road on otherside ....so an easy launch from rest area carpark on that side....lake must be up to 2 klms across ,much longer other way...windfarm on extreme right of pic. This is a once in a generation lake level .
