This is just a state Lake. I would call the DNR and they could tell you if there were any rules against it.
Chris, It may surprise you. I went to lake erie thinking it would be like that too. After I got down about 15 feet or so it was 50 foot of visibility. I didn't expect that there so it's worth a shot. Never know what you could find down there.
Even if you could I would wonder how far one could see. The water is very dingy. Good luck!
