Site details

Gilboa Quarry in Putnam County is widely regarded as the Midwest's premier inland dive site, a 14+ acre spring-fed former limestone quarry operated commercially for diving since 1990. Depths range from 25-foot training shelves to about 140 feet along sheer limestone walls, with sunken attractions including a Grumman airplane, a Sikorsky helicopter, school buses, boats and the 'Nemo's Garden' freshwater underwater biosphere. The quarry is famous for its resident five-foot paddlefish and visibility that averages 30-40 feet.
