Convict Spring has an oval shaped pool framed by a concrete retaining wall.
Concrete steps and a slide lead down into the pool and there are two access ladders. The pool measures 60 ft (18.3 m) long and 18 ft (5.5 m) wide. The spring was not flowing during the November 2002 visit and neither the vent nor the pool bottom could be seen due to the stagnant water. Maximum depth of the pool measures 24 ft (7.3 m). The water is greenish brown and murky, with a thin green algae layer. Limestone crops out along the spring pool edge. The dry, narrow spring run is only a few inches deep and runs 150 ft (45.7 m) east to the Suwannee River. On one side of the spring pool, high ground rises to a picnic area. On the other side, a wooden boardwalk leads down to the spring. The spring is surrounded by grass and trees in a private recreation area developed for scuba diving, camping, and other recreational activities. Discharge on July 7, 1997 measured 6.31 ft3/sec(4).

Bill’s Description:

Sidemount only cave. Has a little bit of flow, 60’ is excellent visibility. Approximately 1800’ of penetration. Very enjoyable & challenging dive.
