Hurricane Irma’s churning seas damaged and displaced buoys that mark areas with specific regulations, assist with navigation, and provide information. Florida Keys National Marine Sanctuary asks boaters to report damaged or missing line, missing buoys and found buoys to 305-852-7717 from Key Largo to Marathon and 305-809-4727 for Marathon through Key West and the Dry Tortugas.

Yellow, 30-inch diameter buoys mark zones such as Sanctuary Preservation Areas, Ecological Reserves and Special-use Research Only areas. Spar buoys are cylindrical, tall and white with orange markings for Wildlife Management Areas and sites on the Shipwreck Trail.

The nearly 500 mooring buoys in the sanctuary are 18 inches in diameter with a blue stripe. They provide an alternative to anchoring, which can break and damage the coral reef. Anchoring is prohibited on coral in waters less than 40 feet and when the bottom is visible.
