As far as I know, no camping allowed at the lake any longer but I could be wrong.
Casade camp would be a good choice. Centrally located and you can access most the area you want to hunt and only a couple of miles past the lake.
Follow past Wenas Lake to the end of the road and take Aoutobond (SP) Road untill after you cross the creek, once you cross the creek, you are there. Just pick a spot to camp.
