NBM Dive Site Resource
Little River Springs
O’Brien, Florida, United States
TECHNICAL DIVE REQUIRED FOR CAVE PENETRATION — The open-water basin or cavern zone may support less advanced activity where current site rules allow, but entering the cave system requires specialized cave-diving training, redundant equipment and overhead-environment procedures.

Diver-reported temperatures
Automatically checked observations from dives during the past 14 days. Three reports are visible at a time; scroll for more.A report that passes the automatic checks will appear here with the dive date, diver’s display name, and temperatures at each depth.
Reports are automatically checked for plausible dates, depths, and temperatures. They are observations, not forecasts; confirm conditions before diving.
Why divers know this place
Highlights
High flow and Suwannee River tannic intrusion can make the system unsuitable; overhead entry requires proper cavern/cave training
Before you arrive
Access notes
High flow and Suwannee River tannic intrusion can make the system unsuitable; overhead entry requires proper cavern/cave training Confirm current rules, hours, water level, visibility, fees and emergency plan directly before travel. Cave penetration is not recreational open-water diving. Present required certification, register or obtain permission where applicable, use a qualified buddy team, and confirm current flow, visibility, closures and landowner or park rules.
Plan within your training
Conditions and hazards
Cold-water exposure, changing visibility and water level, current or flow, submerged timber/rock, entanglement, wildlife, difficult entry/exit, and separation from the surface. Any overhead or technical route adds loss-of-line, gas, depth, decompression and rescue-limit hazards. Permanent overhead, no direct ascent, darkness, silt-out potential, restrictions, line entanglement, high flow or siphon conditions, complex navigation, gas-management demands and possible decompression obligations.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
