Site details

A Maryland artificial reef site east of Ocean City whose bottom slopes gently from about 70 ft on the west side to 50 ft on the east. In 2008-2009 stainless steel subway cars were deployed here alongside barges and concrete rubble, creating moderate-relief habitat for sea bass, tautog and flounder. It is a regular stop for Ocean City fishing, diving and spearfishing trips.
