Dive sites in United States of America

Beaver Lake Scuba Park lies in northwestern Arkansas's Ozark Mountains. Local operators use the site for open-water training and navigation practice. Guide ropes trace a path across a silted limestone slope, linking sunken boat hulls, a car frame, and submerged platforms. In midsummer, a thermocline hits around 6 meters depth, dropping water temperatures abruptly.

At Key Largo Dry Rocks in John Pennekamp Coral Reef State Park, the bronze Christ of the Abyss statue sits on a concrete pedestal under eight meters of water. Italian sculptor Guido Galletti created the nearly three-meter figure, installed in 1965 with arms outstretched toward the surface. Surrounding spur-and-groove reef formations hold sea fans, brain corals, and schooling yellowtail snappers.

On Kauai's southern coast near Poipu, Koloa Landing sits inside a sheltered horseshoe bay that once served as a commercial whaling port. Divers enter from an old concrete boat ramp into shallow water. The reef extends along two basalt lava fingers covered in hard corals, ending at a sandy floor at 12 meters depth. Resident green sea turtles rest under lava ledges alongside morays, including dragon and snowflake eels.

Martha's Quarry in Wilson County, Tennessee, is a flooded limestone pit used for dive training and navigation practice. Steep rock walls descend 25 meters to a basin containing a school bus, cars, boats, training platforms, and a pump house. Spring and autumn yield the clearest water. Summer warms the surface but triggers algae blooms that cut visibility.

Drifting this central Florida freshwater river moves you over sandy beds, eelgrass, and active spring vents bubbling through limestone. Rainbow Springs feeds the river at a constant 22°C year-round. The mild downstream current carries divers past submerged cypress roots, freshwater fish, and turtles. Florida law requires every group or buddy team to tow a diver-down flag on a float because recreational boaters share the water.

White Star Quarry in Gibsonburg, Ohio, is a spring-fed limestone quarry used for scuba training and local recreational diving. Depths across the main floor average 12 meters, with pockets reaching 20 meters. Submerged guide lines connect sunken attractions, including a small airplane, boats, automobiles, and training platforms. Summer thermoclines drop water temperatures sharply below 6 meters.
