Artificial Reefs

Maryland has artificial reef sites located in both Bay and ocean waters. These are collaborative projects with the Maryland Department of Natural Resources, the partner organizations of the Maryland Artificial Reef Initiative (MARI) and the Ocean City Reef Foundation (OCRF).

MARI is a volunteer organization including more than 60 private, state, and
federal partners dedicated to preserving, restoring and creating fish habitat in tidewater Maryland. MARI acts as a funding mechanism under an agreement with the Coastal Conservation Association Maryland using private and corporate donations for reef development.

OCRF works to build the reefs off Ocean City and, in partnership with MARI, accepts donations as a non-profit 501(c)(3) at
