Dive Site Overview

Causeway Reef #28, like much of the broader Indian Shores Reef system, comprises a varied collection of artificial structures designed to foster marine growth. Early deployments in Pinellas County starting in 1965 included items such as concrete pillboxes, metal pipes, and later, concrete slabs, culvert sections, and handrails.

Divers exploring this area can encounter several notable wrecks; among them are the main structures of two World War II Landing Ships, LSM 1 and LSM 2, located at depths reaching approximately 30 m (98 ft), requiring an Advanced Open Water certification. Further highlights include an 80 ft (24 m) steel-hulled tugboat, the Orange, sunk in 2004, and a 240 ft (73 m) upside-down salt hopper barge resting between 10-21 m (32-68 ft).

These submerged features create intricate environments, supporting diverse fish populations and providing ample opportunities for exploration. The site's topography varies from open reef sections to more enclosed wreck environments, catering to different dive preferences.

Dive Experience & Conditions

Visibility around Causeway Reef #28 generally presents good conditions, often reaching 14 m (45 ft) when local currents and weather align favorably. Occasionally, a slight current can be present, creating opportunities for gentle drift dives along certain reef sections. Divers will find various structures, ranging from concrete modules to significant shipwrecks, which accommodate diverse dive profiles. For Open Water certified divers, exploring shallower artificial reef areas is readily accessible. Meanwhile, Advanced Open Water divers can descend to deeper wreck sites, including the main Landing Ship structures, which demand a higher skill level. Expect a blend of open reef areas and more intricate, confined structures as you navigate this artificial environment. This varied topography allows for both relaxed observation of established marine life and more engaged wreck exploration, depending on your chosen dive within the broader reef system and your specific certification level. Approaching these sites requires attention to buoyancy, particularly near the many crevices and ledges that serve as habitat.

Dive Difficulty & Safety Guidelines

While Causeway Reef #28 offers rewarding diving, understanding potential hazards is essential for a safe experience. Strong currents can be present, particularly around the Upside-down Barge Wreck, where they are reported to potentially seal off entrance points within minutes. Penetrating any wreck, especially the barge, is explicitly considered dangerous due to these unpredictable currents and the inherent risks of overhead environments. Divers should ensure they possess the appropriate certification level for planned depths and wreck exploration, with Advanced Open Water recommended for the deeper Landing Ship wrecks. Always dive within your training limits and consider local dive operator briefings for up-to-date conditions. Maintaining good buoyancy control is crucial, especially when navigating around the artificial structures and fragile marine growth.
