Dive Site Overview

Development of the I-1, Lynn Silvertooth site began with multiple deployments, establishing its historical context as a continually evolving artificial reef. Records indicate initial contributions included concrete blocks in May 1980, followed by concrete rubble in June 1981.

From 2003 to 2005, substantial additions arrived, incorporating extensive bridge pilings and decking from the old Ringling bridge. Site #12, for example, specifically received six pieces of bridge decking with rails in October 2003. This consistent effort has utilized a range of materials—from concrete reef balls and additional rubble to various bridge components and concrete pilings—to construct a substantial and varied artificial reef system.

The original intent was to create a fixed span of underwater structures, thereby attracting marine life and providing numerous dive opportunities. Now, the complex spans a wide area of 2.2 million square feet.

Divers can explore many different structures scattered across its various numbered sites, all generally sitting at a base depth of 30 m (100 ft) with significant vertical relief up to 15 meters (49 ft) in some areas, including site #12 itself.

Best Time to Dive

Optimal diving conditions at the I-1, Lynn Silvertooth site generally emerge from May through September. During these months, dive scores are frequently rated "Excellent," providing the most favorable experience. Air temperatures consistently range between 25.5°C (78°F) in May and peaking at 28.5°C (83°F) in July and August, then gently tapering to 27°C (81°F) in September. Wave heights also tend to be lower during this period, often below 0.5 meters (1.6 feet), contributing to smoother boat rides and calmer water entries. While rainfall can be higher in the summer, particularly in August, it typically doesn't deter diving unless associated with stronger winds or storm systems. January through April and October through December still offer good diving prospects. Air temperatures during cooler periods are between 15.5°C (60°F) and 24.5°C (76°F) with slightly higher average wave activity. Divers might consider cooler periods for potentially better visibility, as summer algal blooms can sometimes affect clarity.

Dive Experience & Conditions

Upon descending to the I-1, Lynn Silvertooth site #12, divers typically reach a maximum depth of 30 m (100 ft). This specific site's primary structure involves bridge decking with rails, creating intricate nooks and overhead environments to explore. Depths around these features maintain a consistent 30 m (100 ft). Structural relief can reach up to 15 meters (49 ft) in some areas, including this specific site, offering significant vertical interest. Water temperatures are not consistently reported but generally align with Gulf of Mexico averages for this depth, likely within 22-27°C (72-81°F) during warmer months. Visibility here varies depending on local currents and seasonal factors. While some inshore west coast of Florida locations might see 0-20 feet (0-6 m), offshore sites like Lynn Silvertooth generally tend to offer better clarity, though local conditions and recent weather systems can impact it. Dive is suitable for advanced open water divers due to its overall depth.

Dive Difficulty & Safety Guidelines

Experienced divers always recommend prioritizing awareness of local boat traffic, especially when operating near the I-1, Lynn Silvertooth site. A notable hazard at this location is the presence of cut or discarded fishing line, which can pose entanglement risks. It's highly advisable to carry a dive knife or line cutter and be prepared to use it. Strictly a boat-access site, it is located approximately 1.5 miles west from Lido Beach. Always monitor sea conditions before planning a dive, as wind and waves can significantly affect surface comfort and underwater safety offshore. Given the site's max depth of 30 m (100 ft), divers should be proficient with their deep diving procedures and nitrogen management. Proper buoyancy control not only helps protect the artificial reef structures but also minimizes stirring up sediment, which can reduce visibility for yourself and others.
