The Sadie Thompson is a wreck site serving as an artificial reef in the Great Lakes region. Located 1609 metres from shore, this site requires boat access and is suited for intermediate divers. The wreck lies at depths between 2 and 35 metres. Conditions include mild currents and visibility ranging from 10 to 40 metres. Due to cold freshwater temperatures between 1 and 13 degrees Celsius, drysuits are necessary. Divers must manage risks associated with significant depth, including nitrogen narcosis and the potential requirement for decompression stops. Entanglement hazards exist within the wreck structure, necessitating careful buoyancy control and planning.

The Vienna is a freshwater wreck site located 2414 metres from shore, resting at depths between 36 and 43 metres. This site is suited for intermediate divers, though the significant depth and overhead environment require careful planning. Visibility typically ranges from 10 to 30 metres, and currents are generally mild. Due to cold water temperatures ranging from 1 to 13 degrees Celsius, appropriate thermal protection such as a drysuit is necessary. Divers must access the site by boat and should confirm local facility availability and gas fills before departure. Treat the wreck as an overhead environment and assess your proficiency before attempting any penetration or swim-throughs.

The Myron Wreck is a freshwater wreck located 2400 metres from shore in the United States. Resting at depths between 14 and 17 metres, the site offers visibility of approximately 30 metres, allowing divers to view the entire structure from a single vantage point. The site is suitable for beginner divers, with mild currents keeping the dive manageable. Due to water temperatures ranging from 1 to 15 degrees Celsius, adequate thermal protection is essential. Divers should be aware of entanglement risks posed by the wreck structure and exercise caution during boat entry and exit procedures. Guided tours are available to assist with navigating the wreck.

Mystic Wreck is a freshwater wreck site located in the United States, resting at depths between 2 and 7 metres. The site offers consistent visibility of 30 metres, allowing for clear views of the wreck structure. Conditions are characterised by a mild current, though the water temperature is cold, ranging from 1 to 17 degrees Celsius throughout the year. Due to the cold water, drysuits or thick wetsuits are required. Access to the site is by boat only. Divers should exercise caution regarding entanglement risks within the wreck and remain vigilant for active boat traffic during ascents. A surface marker buoy is essential for all divers.

The Edmund Fitzgerald is a deep freshwater wreck resting on the floor of Lake Superior at depths between 150 and 160 metres. This site is exclusively for divers with technical, trimix, and rebreather certifications due to the extreme depth and overhead environment. Divers must navigate moderate currents and visibility that fluctuates between 5 and 20 metres. The water temperature at depth remains near 1 degree Celsius year-round, requiring significant thermal protection. Access is by boat only, located 27 kilometres from shore. Divers should be prepared for entanglement risks and the complexities of a deep-water wreck environment. Always deploy a surface marker buoy and coordinate closely with boat support.
