The dive
The spring is famous for its incredibly tight entrance.
Profile and sections
The spring is famous for its incredibly tight entrance. Beyond it two distinctly different water sources, one from the north and one from the south, join in one passage that flows out of the spring vent shortly after; several karst windows give access along the way. The water is ~22 °C all year.
The Suwannee River Water Management District bought the spring in 2017; since 2019 it has been a park, managed by the Alachua Conservation Trust. When the trust proposed buoy lines for swimmers and boats in 2019, divers feared losing their access. KUR is exploring, resurveying and photographing the seldom-visited cave.
Practical: information only; swimming is possible in the park.
