What Divers Say

Known for: Longnose gar, Largemouth bass, Striped mullet
Best time: Year-round at 72°F, but visibility is best at low Suwannee River levels (typically late spring-fall dry periods); after heavy rain the tannic river can flood the basin.

Based on community reviews and site data. Conditions vary — always verify before diving.

Site details

Troy Spring is a first-magnitude spring on the Suwannee River in Troy Spring State Park, with a clear bowl dropping to about 70 ft — one of the deepest open-water spring dives in Florida that requires no cavern certification. In the shallow spring run lie the ribs of the Madison, a Confederate sidewheel steamboat scuttled in 1863 to keep it from Union capture. Diving is open-water only: certified divers with a buddy, no lights and no cave penetration.

shorewreck

Open-water diving only — no cave entry and no lights permitted; solo diving prohibited; mild outflow over the vent; the historic Madison wreck timbers are fragile and protected (do not touch); Suwannee River floods can brown out the basin.
