Never dived there before only water skied. The lake has a sunken town at the bottom of the lake about 30ft down from the Fairfield causeway by the golf course. You can enter by shore here or rent a boat from the Quaker town marina. (Pontoon boat for $160. Or $80 split) . $9.fee for park entrance need to sign a wavier at the DNR office have open water cert. and a inflatable diver down bouy. I have a flag for boat. If we go that route. All questions about the lake are on line for in-depth details.
