Artificial Reef Locations
Map and Coordinates
Try our new and easy to use Artificial Reefs Interactive Map (link leaves DEC website) to find out more about reef site characteristics, materials used, coordinates of patch reefs, and the history of deployments.
DEC manages 12 artificial reefs in the marine district. All are located near harbors or inlets for easy access to fishermen and divers and are found on both the north and south shores of Long Island:
- Two reefs in Long Island Sound
- Two reefs in Great South Bay
- Eight reefs in the Atlantic Ocean off the south shore of Long Island.
Site details and GPS coordinates can be found in the table below. The latitude and longitude coordinates pinpoint the corners of the artificial reef sites.
