Pinellas County Artificial Reefs
FAQs

What are artificial reefs?
An artificial reef is a man-made, underwater structure built to promote marine life. In 1975, the Pinellas County Division of Solid Waste began creating artificial reefs from clean inert debris such as concrete. Since then, approximately 50,000 tons of reef material have been deployed.

Is there still a Pinellas County artificial reef program?
Yes. Due to budget cuts, there is no longer a full-time reef crew on staff, and the Tortuga barge that was used for deploying reef materials has been sold. However, the reefs will continue to be maintained and expanded.

How many Pinellas County reefs are there?
There are 13 offshore reef sites and 29 inshore reefs, and one in Tampa Bay, north of the St. Petersburg Municipal Pier. View reef maps or GPS coordinates.

How are artificial reefs made?
The Pinellas County artificial reefs are constructed from environmentally safe construction and demolition waste. Items such as concrete pipes, steel beams or entire ships are carefully placed on the ocean bottom. Within about two weeks, algae and barnacles attach to the reef material. Soon, fish come to feed on these creatures. Within a year, the reef begins to support coral growth.

What is the purpose of the reefs?

Create valuable marine habitats in areas with featureless bottom Divert clean usable materials from the waste stream Boost tourism and the local economy by enhancing fishing and diving attractions

What are some of the more unusual items used to create reefs?
The Pinellas II reef features three vessels: a steel barge, the U.S. Coast Guard Cutter Blackthorn and a tug boat Sheridan. Many divers consider this area the best wreck dive in West Central Florida. Other reefs offer a shrimp boat, WWII Navy diving craft, and 10 Army tanks. View descriptions and GPS coordinates for each reef.

Are donations of reef materials accepted?
Yes, but we can accept only large-scale materials such as the concrete debris from a bridge demolition. Small amounts of concrete or steel from a homeowner are not usable. Potential reef materials are carefully screened before being accepted to make sure they are safe, non-polluting, weigh at least 500 pounds each and have adequate structural integrity.
