What divers may encounter
Three reviewed connections are featured here. Sightings vary by season, conditions, and chance, so they are never guaranteed.
Lake Trout
Salvelinus namaycushCorsican lies in about 160 feet of Lake Huron water. NOAA documents lake trout in the sanctuary fish community, so divers may see a fish passing above or alongside the wreck.

Lake Whitefish
Coregonus clupeaformisLake whitefish are documented in Lake Huron by NOAA and use cool bottom habitat. A fish may cross the wreck or adjacent lakebed when conditions align.

Burbot
Lota lotaNOAA notes that burbot often appear at deeper Lake Huron shipwrecks. The most plausible sighting is close to shaded wreck structure or the bottom.

History and significance
On a foggy morning in June, the steel steam barge Corsica collided with the wooden schooner Corsican off Thunder Bay in Lake Huron. The schooner was nearly cut in two and went to the bottom instantly taking its entire crew with it. Today, this grave site rests on the lake bottom. The cabin and stern of the wreck have large sections missing and piles of jumbled wreckage cover the collapsed deck. The ship’s steering wheel is wrenched upwards and no longer attached to the rudder. The bow windlass is still wrapped with anchor chain and rigged spars rest atop the wreckage, as well as in the adjacent lake bottom.
Before you arrive
Access notes
Technical dive only. Confirm current conditions, mooring status, gas plan, decompression plan and operator requirements before departure. NOAA coordinates are reference points, not navigation instructions.
Plan within your training
Conditions and hazards
Depth beyond recreational limits, decompression obligations, cold water, limited light, changing visibility, entanglement and possible wreck overheads. Penetration requires separate wreck-penetration training and planning.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
