Map of Matagorda

Matagorda

Texas · Up to 18.3 m

The Matagorda Nearshore Reef (TPWD site BA-439) is a 160-acre artificial reef in Texas state waters of the Gulf of Mexico, roughly 10 miles off the Matagorda County coast. Built under the Texas Parks and Wildlife Artificial Reef Program with Deepwater Horizon restoration funds, it consists of three-sided concrete pyramids (8 ft tall, 10 ft bases) placed on sandy bottom in about 60 feet of water. The structures were deployed to create hard-bottom habitat for Gulf marine life and to give anglers and divers an accessible nearshore destination, part of the largest nearshore reefing effort in the program's history.

Map of Nordmeer Wreck (Thunder Bay National Marine Sanctuary)

Nordmeer Wreck (Thunder Bay National Marine Sanctuary)

Michigan · Up to 12.2 m

The Nordmeer was a 471-ft German steel freighter that ran onto Thunder Bay Shoal in November 1966 after turning the wrong side of the marker buoy. Once partially above water, the wreck has collapsed and now lies fully submerged in about 40 ft of Lake Huron roughly seven miles north of Thunder Bay Island, with the large diesel engine and big steel hull sections to explore. It is one of the most visited dive sites in Thunder Bay National Marine Sanctuary and suits newer wreck divers in calm conditions.

Canyon Lake, a US Army Corps of Engineers reservoir on the Guadalupe River between Austin and San Antonio, is the standard open-water site for Hill Country dive shops. Comal Park on the south shore and North Park near the dam offer shore entries onto bluff walls, submerged cars, boats and standing timber, with depths over 100 ft available off Comal Park. Visibility is typical Texas-lake (5-12 ft above the thermocline).

Map of Sport Wreck (Sanilac Shores Underwater Preserve)

Sport Wreck (Sanilac Shores Underwater Preserve)

Michigan · 7.6–13.7 m

The Sport, launched in 1873, was the first steel-hulled tug on the Great Lakes and sank in a December 1920 gale off Lexington; the crew washed ashore alive. Rediscovered in 1987, she rests upright with a slight starboard list in about 45 ft of water roughly three miles off Lexington in the Sanilac Shores Underwater Preserve, rising about 20 ft off the bottom with tools and relics scattered around the site. In 1992 she became the first Michigan shipwreck to receive its own Michigan Historical Marker, and her shallow depth makes her a favorite first Great Lakes wreck dive.
