not sure, lots of marinas to launch at...only free launch i know of is at the causeway on chemong. ive caught skis on the west side of the gannon narrows and east side east of kishgo south end near emily and up in the north end near nogies creek.
The lake once again, I cannot stress enough is loaded with musky. Go poke around and you will find them, its the best place to hone your blade as far as I am concerned. Theres plenty of 40+ fish to wet your chops and learn the ropes.
