Dive Site Overview
Within the broader Lettuce Lake system near Tampa, Florida, divers encounter a distinct spring environment. A shallow, clear water lake, spanning approximately 45.7 m (150 ft) in diameter, serves as the central feature, cradling the main spring vent.
Records consistently describe a dark, detritus-covered bottom inside the lake. The primary spring vent descends to a maximum depth of 2.7 m (8.8 ft). Early historical observations detail varied flow patterns, including a natural run that once flowed southward.
Later, canal construction and a 1.8-meter (6-foot) high berm rerouted this natural outflow. Water now primarily drains southwestward from the lake through a 61-meter long canal, roughly 0.3 meters deep and 1.8 meters wide.
This canal subsequently merges with a larger channel, extending about 198 meters south before connecting to the Tampa Bypass Canal. Such a confined setup delivers a specific underwater experience.
A March 2003 assessment noted no distinct surface boil, indicating flow varies depending on conditions, even while generally approachable for new divers. Expect a contained and shallow spring setting, well-suited for focused observation.
Best Time to Dive
Planning a dive at Lettuce Lake Spring is favorable year-round, as indicated by consistently excellent dive scores across all months. Divers can expect comfortable conditions, though seasonal variations do occur. Air temperatures range from milder averages of approximately 14.4°C (57.9°F) in January to warmer averages around 27.7°C (81.9°F) in July and August. While specific water temperature data for Lettuce Lake Spring isn't consistently reported, Florida springs typically maintain a stable temperature range, often around 20-22°C (68-72°F). Considering rainfall patterns, drier periods, like November averaging 0.7 mm of rain, might present clearer surface conditions. Conversely, wetter months such as August, with an average of 7.1 mm, could introduce more runoff into the surrounding lake, potentially affecting visibility in the broader system. A 2008 report indicated high to medium visibility. Overall, the consistent air temperatures and minimal wave action create a welcoming environment for open water diving throughout the year, with a slight preference for drier seasons to maximize visibility.

Dive Experience & Conditions
Upon entering Lettuce Lake Spring, divers find a shallow, clear water environment defined by its dark, detritus-covered bottom. At the central spring vent, the maximum depth is a recreational 2.7 meters. Visibility here varies, with historical reports indicating a range from high to medium depending on recent weather. Conditions typically feel gentle; earlier assessments noted the spring often lacks a strong surface boil, suggesting minimal current within the immediate dive zone. Exploring the lake, divers operate within a confined system, roughly 45 meters in diameter. This site provides a straightforward experience, well-suited for new divers or open water training. Underwater, the focus remains on the spring vent and the shallow lakebed. A relaxed pace is encouraged, allowing for easy observation of features without encountering complex currents or significant depths.
Dive Difficulty & Safety Guidelines
When approaching Lettuce Lake Spring, divers should prioritize awareness of the surrounding natural environment. While generally considered a safe, introductory open water site, encounters with local wildlife, specifically alligators, have been reported; they are typically wary of divers. Exercising caution on the rocky outskirts of the canal is also advisable, as water moccasins may inhabit these areas, particularly when basking in the sun. This site is exclusively designated for open water diving; cave diving or venturing into overhead environments is not permitted. Divers must adhere to all local regulations and park guidelines, which often include restrictions on equipment and behavior to protect the delicate spring ecosystem. Maintaining proper buoyancy control is crucial to avoid disturbing the detritus-covered bottom, preserving visibility for all. Always plan your dive within your certification limits, respecting the shallow depth and confined nature of this particular spring system.

Verified equipment recommendations for this dive site are being reviewed and may be added as additional source checks are completed.
Recommended Dive Suit
Divers planning deeper dives may feel cooler than those staying in shallower areas.
Based on regional estimates and current weather, the likely required exposure protection is a 3mm wetsuit. Note that local currents and upwellings can alter this. Due to unpredictable weather patterns, conditions may change rapidly. A significant temperature drop is forecast; strongly suggest bringing a backup warmer suit option. Carrying a secondary suit is common practice among experienced divers.
Because recent water temperature readings are not available for Lettuce Lake Spring, the guidance below is based mainly on current air conditions and seasonal expectations. Current surface air temperatures are roughly 28°C (82°F).

Marine Life at Lettuce Lake Spring
Upon entering Lettuce Lake Spring, divers might first notice smaller freshwater species adapting to the spring environment. While specific aquatic marine life details are not consistently reported, freshwater fish are typically present in such spring-fed systems. Overhead, divers should be observant for surface wildlife. Alligators have been occasionally noted in the area, generally demonstrating a natural avoidance of human presence. Additionally, the canal's rocky banks may shelter water moccasins, though these are typically seen basking above water. Focus here is often on the geological features and the serene spring setting rather than a dense aggregation of large marine fauna.
