Shotline Diving Wreck Profile

• Vessel Names / Site Name: Crane & Front Loader Debris Field
• Registry Number(s): None – not a registered vessel
• Date of Incident: Estimated 1980s (exact year unknown)
• Depth: 130 ft (39.6 m)
• Body of Water: Lake Michigan
• County: Manitowoc County, Wisconsin
• Nearest City: Two Rivers, WI
• Coordinates: 44° 10.37′ N / 87° 26.51′ W

Vessel Type / Cargo Description

• Vessel Type: None – site represents lost cargo/debris field
• Cargo: 1x diesel‑powered continuous‑track crane and 1x diesel‑powered Caterpillar front loader; miscellaneous tools and metal debris scattered across a rock and slag base
• Hull Material: N/A (steel construction equipment only)
• Propulsion: None (equipment only)
• Masts: 0
• Associated Barge: Presumed standard lake construction/dredging barge (identity unknown)

Description

The site consists of industrial construction machinery deposited on the lakebed:

• A continuous‑track crane resting upright.
• A Caterpillar front loader lying on its side on a pile of slag and riprap.
• Scattered tools, chains, cables, and small components interspersed among the debris field.

The site lies in 130 ft (39.6 m) of water, making it accessible only to advanced technical divers. Visibility can be low, and temperatures remain cold year‑round.

Historical Context & Theories of Loss

Archival research and diver documentation suggest this debris field resulted from a maritime mishap involving a construction barge in the 1980s.

Three primary theories of origin exist:

1. Barge Capsize: A heavy‑equipment barge capsized in rough seas, losing its load.
2. Cargo Shift: Heavy seas caused the machinery to roll off the deck.
3. Intentional Dumping: Less likely but possible, that obsolete machinery and rock were scuttled as part of harbor development.

Despite multiple searches in newspaper archives, Coast Guard bulletins, and OSHA/USACE reports, no official record or public incident report has been located. This suggests the event caused no fatalities and may have been handled internally by a local contractor or the U.S. Army Corps of Engineers during routine breakwater or dredging operations.

Final Disposition & Wreck Condition

• Status: Non‑navigational debris; considered a dive site.
• Condition: Machinery largely intact; surface corrosion and biofouling present.
• Surrounding Area: Slag/riprap pile with scattered tools and debris.
• Hazards: Sharp metal edges, entanglement risk, depth and cold.

Located By & Documentation

• Discovery: Popularized by local technical divers; exact first discovery year unknown
• Methods: Open‑circuit scuba and sonar surveys
• Photography/Documentation: Present on regional dive maps and Wisconsin Historical Society’s Wisconsin Shipwrecks database

Notices to Mariners / Advisories

• Official hazard listing: None
• Navigation risk: Minimal due to depth (130 ft / 39.6 m)

Shore Dive / Technical Dive Information

• Entry: Boat access only; 1.5 mi offshore from Two Rivers, WI
• Depth: 130 ft (39.6 m)
• Water Temperature: 38–45 °F (3–7 °C) typical
• Visibility: 5–30 ft (1.5–9 m) depending on season
• Emergency Contact: 911 (Two Rivers, WI) / U.S. Coast Guard Sector Lake Michigan
• Recommended Certification: Advanced/Technical Deep Diver

Conclusion

The Crane & Front Loader Debris Field is a rare example of an industrial equipment loss site rather than a true shipwreck. It represents the working history of Great Lakes harbor construction in the late 20th century. While not historically significant as a vessel, it has archaeological and recreational dive interest, illustrating the risks of lake transport of heavy construction gear.

Continued research into local contractor records, U.S. Army Corps archives, and microfilm newspapers may one day identify the exact barge and incident responsible for this unique underwater site.
