Site details

Russell's Reef, also known as Great Gull Reef, is a Maryland artificial reef of slightly under 1,000 acres located 4.2 nautical miles southeast of the Ocean City Inlet on the Great Gull Bank. Concrete reef material in roughly 30-45 ft of water attracts sea bass, tautog and flounder, and the site's proximity to the inlet makes it a convenient shallow dive and spearfishing area.
