The reef comprises 714 Redbird (R26–R36 World's Fair series) New York City Subway cars, 86 retired tanks and armored personnel carriers, eight tugboats and barges, and 3,000 tons of ballasted truck tires.
The amount of marine food has increased 400 times over 7 years.
The site is the most visited reef site off Delaware's coast, receiving more than 10,000 fishing parties annually, and is home to numerous marine species, including black sea bass, flounder, blue mussels, sponges, barnacles and coral. Also, tuna and mackerel hunt at the reef. The site has become so popular that fishermen steal from each other, and other states apply for the next subway cars to be dumped in their waters.
