Grecian Wreck (Thunder Bay National Marine Sanctuary)
Michigan · 22.9–30.5 m
The Grecian, a 296-ft steel bulk freighter launched in 1891, sank in 1906 while under tow after a collision and now lies in roughly 100 ft of water in Thunder Bay National Marine Sanctuary off Alpena. The deck is reached around 75 ft, and divers can explore the triple-expansion engine, boiler, decks and cargo holds; the collapsing midships section can be disorienting. NOAA typically places mooring buoys on both bow and stern in season.

Greenbo Lake Scuba Refuge
Kentucky · Up to 7.6 m
A designated 10-acre scuba refuge inside Greenbo Lake State Resort Park in northeastern Kentucky, the first of its kind in the state park system (opened 2013). The 225-acre fishing lake averages about 25 ft deep in the refuge area and gives Tri-State (KY/OH/WV) divers a sanctioned freshwater training and fun-dive spot. Divers sign in and out at the lodge and must display dive flags.

Greers Ferry Lake
Arkansas · 6.1–18.3 m
A Little Red River reservoir in north-central Arkansas ranked among the cleanest and clearest lakes in the country. When the dam was completed in the early 1960s the town of Higden was relocated, and submerged homes, building foundations and roadbeds remain popular dive targets, along with island walls and rock structure mapped by the regional dive community. Diving is staged from Corps recreation areas such as Dam Site and Sugar Loaf.

Gull Lake - Ross Township Park Scuba Park
Michigan · 0–33.5 m
Ross Township Park on the east shore of Gull Lake near Hickory Corners is southwest Michigan's most developed inland shore-diving site, with an extensive sunken attraction park placed for divers. Submerged features include training platforms, a car frame, ~40 ft of railroad track, several boats including a large wooden sailboat and an ice boat, a motorcycle, a phone booth, an ice shanty and an underwater climbing wall, mostly in 10-60 ft. The spring-fed lake reaches over 100 ft deep with visibility commonly 20-30 ft, and the park is heavily used for open-water training.

Gypsum Prince
Delaware · 14.6–24.4 m
A British-built freighter that sank in 1942 after colliding with the tanker Voco at the end of the Harbor of Refuge breakwater off Cape Henlopen, then was wire-dragged and demolished as a navigation hazard. The wreck today is a sprawling field of twisted plates and machinery on sand in roughly 50-80 ft of water that shelters lobster, tautog and sea bass. Its position at the bay mouth means strong currents, and local charters dive it at slack tide.

Haigh Quarry
Illinois · 4.6–25.9 m
Haigh Quarry, nicknamed the 'Caribbean of the Midwest,' is a 12-13 acre spring-fed former limestone quarry in Kankakee that has operated as a family-run dive park since the Haigh family bought it in 1978. The north side is a shallow 20-30 foot training area divided from the deeper south basin (40-60 feet, with an 85-foot hole in the southeast corner) by the beach walk-in entry. Attractions include a 33-foot cabin cruiser, a military dump truck, an amphibious LARC, a step van and the original rock crusher, with abundant fish including giant paddlefish.

Hanover Wreck
Wisconsin · 5–8.2 m
The schooner Hanover, a 100-ft grain carrier built in 1853, grounded on a shoal south of the Strawberry Islands during a November 1867 storm while running light from Chicago to Oconto, and settled in 27 ft of water. Rediscovered and documented in 2014 and added to the National Register in 2015, the wreck's bow, centerboard trunk, stern and rudder are visible in clear water, though sand and mussel shells cover varying amounts of the site from year to year. An easy boat/snorkel dive near Fish Creek.

Harbor of Refuge Breakwater (Outer Wall)
Delaware · 1.5–18.3 m
The mile-and-a-half-long outer breakwater off Cape Henlopen, built of more than a million tons of granite in the early 1900s to shelter the mouth of Delaware Bay. The submerged rock slope is heavily encrusted with mussels and attracts tautog, sheepshead, striped bass and record-class black drum, making it the region's storied freediving and scuba spearfishing site; the Gypsum Prince wreck lies at its seaward end. Depths along the wall run from the surface rocks down to about 40-70 ft on the surrounding bottom, with strong tidal flow around the structure.

Harborview Beach
Massachusetts · 1.5–6.1 m
Harborview Beach, beside the Sesuit Harbor breakwater in Dennis, is an easy, shallow Cape Cod Bay shore dive and a favorite quick dusk or night dive for locals. Navigation is simple - keep the breakwater on your right and pick through the rocks for lobsters, crabs, and other critters. Most of the dive is around 10 ft at high tide with a maximum of about 15-20 ft at the end of the breakwater, making it a great beginner site. Dive within an hour of high tide and watch for fishermen on the rocks and boat traffic in the harbor channel.
Shore entry
Hathaway Pond
Massachusetts · 1.5–17.4 m
Hathaway's Pond is a 20-acre freshwater kettle pond in Barnstable considered one of the best training sites in New England, with a maximum depth of about 57 ft. Attractions include a wooden training platform at roughly 20 ft about 70 ft off the swim beach, a 35-ft cabin cruiser (the Field & Sea, sunk in 1979) at about 30 ft, and a sunken car. With no current and easy beach entry it hosts certification classes year-round and serves as the standard fallback when Cape Cod ocean sites are blown out. The pond is stocked with trout and also holds bass, perch, sunfish, and catfish.

Hennepin Wreck
Michigan · Up to 70 m
The Hennepin, built 1888 and converted in 1902 into the world's first self-unloading bulk carrier, foundered on August 18, 1927 about 15-20 miles off South Haven; her entire conveyor and A-frame unloading system is still in place. Located by Michigan Shipwreck Research Associates in 2006, she sits upright in about 230 ft of Lake Michigan within the Southwest Michigan Underwater Preserve. This is a serious trimix technical dive — cold, dark, and far offshore — but historically one of the most important wrecks in the Great Lakes.

Massachusetts · Up to 30.5 m
Heroic, a 97-ft wooden-hulled former U.S. Navy coastal minesweeper (USS Heroic, AMc-84) converted to a Gloucester eastern-rig dragger, caught fire and sank on 21 August 1969 atop Stellwagen Bank. The wreck rests in about 100 feet of water with its large Atlas diesel engine surrounded by hull sections, trawl winch, and anchor chain, much of it draped in old nets. It is an official NOAA-listed sanctuary dive site with a subsurface mooring installed in partnership with Northern Atlantic Dive Expeditions.
