VESSEL TYPE DESCRIPTION

The wreck at this location is unidentified, and its type remains undetermined. The structure’s shallow depth suggests it could be the remains of a vessel or submerged debris posing a navigational hazard. The wreck may consist of wooden or metal fragments, but no detailed information about its construction, size, or features is available.

HISTORY

The wreck was identified and documented during survey H9782/78. Divers confirmed the least depth at 4 feet (1.2 meters), indicating a submerged obstruction close to or breaking the water’s surface. However, no historical records are currently associated with this site, leaving the wreck’s origin and sinking circumstances unknown.

Shallow wrecks like this one are often the result of catastrophic events such as:

•Foundering during storms.

•Structural failure leading to a rapid sinking.

•Intentional scuttling or abandonment near shorelines or shallow areas.

The absence of identifying features or artifacts makes it challenging to link this wreck to a known historical vessel.

FINAL DISPOSITION

The wreck lies in a precarious location in Lake Huron, with the least depth recorded at 4 feet (1.2 meters). This extreme shallowness poses a significant threat to surface navigation, particularly for smaller vessels or those with shallow drafts.

Condition and Visibility:

•The wreck is partially or fully exposed depending on water levels and wave action.

•Unknown structural integrity due to potential decay from prolonged submersion.

NOTMARs & ADVISORIES

The shallow depth of this wreck classifies it as a navigational hazard. Mariners in this area of Lake Huron should:

•Reference Notices to Mariners (NOTMARs) for current hazard warnings.

•Use updated nautical charts that mark the wreck’s location.

•Exercise extreme caution, especially under low-Visibility conditions.

LOCATED BY & DATE

•Survey: H9782/78

•Verification: Conducted by divers during the survey.

•Depth Reported: Confirmed as a shallow hazard at 4 feet.

CURRENT CONDITION & ACCESSIBILITY

•Accessibility: Due to the wreck’s shallow nature, it is highly accessible for further survey work or diving operations.

•Risks:

•Navigation: Direct threat to surface navigation.

•Diving Hazards: Poor Visibility, sharp edges, and potential debris make exploration hazardous.

RESOURCES & LINKS

•Maritime History of the Great Lakes Database: Provides historical context for similar wrecks and maritime incidents.

•NOAA AWOIS Database: May contain additional survey details.

•Local Marine Safety Authorities: Updates on NOTMARs and navigational guidance.

CONCLUSION

The unidentified wreck near Latitude 45.716000°N and Longitude -84.573194°W presents a significant navigational risk due to its shallow depth of 4 feet. The lack of historical or structural information further complicates identifying the wreck and understanding its origin. A complete survey and historical investigation are recommended to assess its condition and to potentially link it to regional maritime events.

This wreck highlights the importance of accurate and up-to-date hazard marking in areas with active navigation to ensure maritime safety.
