Everything you need to know about this dive site.
Dive Site Overview
This artificial reef site primarily characterizes itself through substantial concrete topography. Over 1,000 tons of secondary use concrete material were strategically placed, creating an intricate underwater landscape on a generally sandy bottom.
Divers will find themselves navigating a dense array of 280 concrete culverts, varying in diameter, alongside 40 concrete power poles that range from 6.1 to 13.7 m (20 to 45 ft) in length. Adding to this structural complexity are 260 concrete slabs of diverse sizes. Further additions include 24 concrete junction boxes and 170 concrete pilings, some impressively reaching lengths of 12.2 m (40 ft) and weighing up to 5 tons each.
These numerous and disparate elements collectively form a foundational structure, specifically designed to cultivate a robust artificial reef ecosystem. The initial deployment, completed in May 2011, effectively established a new environment, inviting a variety of local marine life to colonize and thrive amidst the varied concrete shapes.
