Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Encompassing federal waters off Collier County, Tod Sirod Reef stands as a significant artificial reef complex, forming a vital part of the Paradise Coast Artificial Reef Project. Originally designated Collier #1 Reef, its renaming acknowledged a substantial donation, highlighting a successful partnership between public and private conservation initiatives.
The complex's structure primarily consists of modular concrete units, including 340 poles and slabs, totaling thousands of tons of material. These are further augmented by limestone modules and culverts. Deployments, meticulously phased through 2015, established a habitat with relief ranging from 3 to 6 meters (10 to 20 feet) above the characteristically sandy-muddy seafloor.
Average water depths across the site settle around 12-15 meters (40-50 feet). Accessing this reef is typically via private or charter boat from marinas in Naples or Marco Island, a journey generally requiring 30-45 minutes in favorable sea conditions.
This dynamic, human-made submerged landscape supports both recreational diving and fishing, effectively demonstrating how constructed environments foster marine biodiversity in the Gulf.

Best Time to Dive
Planning a trip to Tod Sirod Reef is best during the spring months, particularly May, which consistently earns an 'Excellent' dive score. During this period, air temperatures average around 26.5°C (80°F), with minimal rainfall at about 1.17 mm, creating pleasant surface conditions. Wave heights are generally low in May, around 0.5 meters, and wind speeds are moderate, averaging 24.1 km/h (15 mph). While surface water temperatures in the subtropical Gulf of Mexico range from 21-29°C (70-85°F) annually and can peak over 30°C (86°F) in summer, the calmer spring seas and lower rain chance often provide the most comfortable diving experience. Months like February, March, April, November, and December also offer good diving opportunities with favorable weather patterns.

Dive Experience & Conditions
Navigating Tod Sirod Reef reveals a consistent, shallow offshore environment suitable for intermediate-level divers. Depths typically settle around 12-15 meters (40-50 feet) across the complex, with relief provided by the artificial structures. Surface water temperatures in these subtropical Gulf waters commonly range between 21-29°C (70-85°F) throughout the year, often exceeding 30°C (86°F) during the warmer summer months. Average salinity remains stable at 35-36 parts per thousand, indicative of open ocean influences. The seafloor here consists of a sandy-muddy substrate, a characteristic low-relief bottom that contrasts with the introduced concrete structures. Divers can anticipate moderate currents, which are influenced by the broader Loop Current, bringing nutrient-rich waters to the area. Tidal ranges are small, generally 0.3-0.6 meters (1-2 feet), leading to subtle water exchange, ensuring good light penetration and visibility, though sediment mobility from wave action can occur.
Dive Difficulty & Safety Guidelines
To ensure a safe and responsible dive at Tod Sirod Reef, divers should always adhere to established guidelines. Given the reef's artificial nature and its purpose, explicit restrictions are in place prohibiting heavy anchoring directly on the structures to prevent damage and preserve marine habitats. Utilizing GPS waypoints for precise navigation to the site is crucial, as there are no prominent natural features for guidance. Divers should be mindful of potential moderate currents, especially those influenced by the Loop Current, and plan their dives accordingly. While the site supports recreational fishing, visitors must respect Florida Fish and Wildlife Conservation Commission (FWC) regulations, including species-specific bag limits and seasonal closures. Protecting marine life is paramount; therefore, the taking of protected species such as sea turtles and certain corals is strictly forbidden.
