Dive Site Overview
Delving into the waters of Concrete 'Fish Havens' offers an exploration of purposefully deployed artificial reef sites, meticulously established by initiatives like the Collier County, DNREC, and SWARA programs. These submerged structures are designed to replicate natural reef functions, actively attracting and sustaining marine biodiversity.
Most dive sites here are found within recreational depths, typically ranging from 9 to 11 m (30 to 37 ft). Divers can navigate through various formations, including large debris fields of concrete culverts and several sunken barges. Sites such as Anchor Eater and the northeastern wreckage are known for specific inhabitants; the latter is a significant Goliath Grouper haven, while Anchor Eater frequently hosts Snook.
This network of artificial reefs serves a vital role, enriching the local ocean environment by providing complex, three-dimensional protection and sustenance for fish against predators and storms. Visibility generally averages around 4.5 m (15 ft), but divers often report exceptionally clear conditions during very calm weather months.
Best Time to Dive
Optimal diving at Concrete 'Fish Havens' often aligns with periods of improved visibility, which can be extremely clear during calm weather. This generally corresponds to the months offering 'Good' dive scores, typically from May through September. During this peak season, average wave heights are significantly reduced, sometimes dropping to around 0.66 m (2.2 ft) in July, compared to higher averages in winter. Air temperatures during these favorable months comfortably range from approximately 24.6°C (76.3°F) in May up to 29.2°C (84.6°F) in August. Rainfall remains moderate throughout the year, with monthly averages between 2.6 and 5.3 mm (0.10 and 0.21 inches). Lower wind speeds, averaging around 22.9 km/h (14.2 mph) in July, further contribute to a stable sea state, making these months ideal for exploring the varied structures of these artificial reefs.

Dive Experience & Conditions
Exploring the Concrete 'Fish Havens' takes divers into a world of purpose-built structures, offering a diverse and accessible terrain. Recreational depths are the norm here, with most sites maintaining a maximum depth between 9 and 11 m (30 and 37 ft). Upon descent, divers encounter a varied landscape composed of concrete culverts, barge remnants, and other deployed materials. These structures rise from the sandy bottom, forming intricate havens for marine life and creating interesting navigation opportunities. Visibility averages around 4.5 m (15 ft) but can fluctuate, offering much clearer conditions during periods of stable, calm weather. While specific water temperatures are not consistently reported for this exact location, they typically follow regional coastal patterns, making a wetsuit a common choice.
Dive Difficulty & Safety Guidelines
Adhering to crucial safety protocols ensures a secure dive experience across these artificial reef sites. Sea conditions can shift rapidly, requiring divers to remain attentive to environmental changes and prioritize safety consistently. Florida State Law strictly mandates displaying a diver-down flag or buoy prominently whenever diving, alerting nearby boaters to your presence. For accurately locating specific offshore reefs, such as Fish Haven #1, #2, and Frangista Reef, a reliable GPS device is essential. Divers planning to visit these havens should possess proper SCUBA training and certification, always staying within their personal limits. A fundamental guideline involves respecting the marine environment: take only pictures, and leave only bubbles. This approach helps preserve the integrity of these valuable underwater habitats.
