As long as you don't get out to portage or retrieve downed birds you should be alright. I know when floating fishing if I don't leave the boat/Canoe/Kayak I don't need permission even though land on both sides might be posted for miles.
I didn't see anything on the Ohio DNR web site about this issue.
