North Carolina · 9.1–18.3 m
The Indra is a 330-ft former US Navy landing craft repair ship sunk in 1992 as artificial reef AR-330, about 10 miles off Atlantic Beach. Resting upright in only 60 ft of water with decks at 40-45 ft and cut-outs for easy access, it is North Carolina's classic first wreck dive and a popular training site. The largely intact hull is packed with baitfish, sea bass, flounder, octopus, and the occasional passing shark.
Wisconsin · 4–5 m
The Goodrich Line steamer Atlanta caught fire and was lost off Cedar Grove in March 1906 while running from Sheboygan to Milwaukee; all aboard escaped. Her lower hull lies mostly intact and partially buried in sand in about 17 feet of water, 800 feet from shore north of Amsterdam Park. The shallow, sandy site has served as an underwater archaeology training venue and makes an easy kayak-dive or snorkel inside the Wisconsin Shipwreck Coast sanctuary.
Colorado · 6.1–30.5 m
A 1,780-acre mountain reservoir near Leadville at roughly 9,900 feet, making it one of the highest commonly dived lakes in the United States. Clear, very cold water offers around 20 feet of visibility over depths of 20-100 feet, with boulder fields and submerged forest along the shores. The extreme altitude makes specialized altitude-diving planning essential; air fills are available in Leadville.
Puerto Rico - Vieques · 1–12.2 m
Former military pier/breakwater on Vieques with artificial-reef structure, macro life, and frequent easy shore-dive use. It is shallow enough for snorkeling and freediving and commonly used for beginner scuba and night dives. Keep clear of pier structure, fishing line, and boat traffic.
New York · 26.8–28.7 m
The Port Jefferson/Mount Sinai Reef is a 50-acre NYSDEC artificial reef in Long Island Sound about 1.79 nautical miles northeast of Port Jefferson Inlet, in 88-94 ft of water. Built from a barge and concrete buoy sinkers with concrete blocks added in 2025, it is a deep Sound reef best suited to advanced/deep divers. Black sea bass, tautog and scup hold on the structure; visibility is variable.

Massachusetts · 1.5–7.6 m
Sandwich Town Beach (Town Neck Beach) is the most popular shore dive on Cape Cod, a shallow Cape Cod Bay site with an unusual series of clay shelves and banks that lobsters burrow into, making it a favorite spot for new lobster divers. Depths run about 15-25 ft, with moon snails, crabs, sea robins, flounder, and tautog over the sand and clay. The site is diveable through the whole tide cycle but is easily blown out by north or east winds and offshore swells, which suspend the clay and create rough entries. A large paid lot sits just over the dunes from the water.
New Jersey · 20.1–22.9 m
Artificial reef built from M-113 Armored Personnel Carrier (APC) NJDEP deployment record: Military vehicle, material: M-113 Armored Personnel Carrier (APC), deployed 1996.
