Gilboa Quarry: spring-fed freshwater diving with clear water and training.
Gilboa Quarry is a spring-fed freshwater dive site in northwest Ohio with clear water, strong training support, and a long list of underwater attractions. The quarry mixes shallow learning zones with deeper walls and platforms, plus sunken planes and vehicles, so the same site works for open-water classes, fun dives, freediving, and snorkel sessions. Its draw is the mix of structure and fish life, including paddlefish, sturgeon, carp, trout, and other freshwater species.
