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:
