Unidentified Tug (Off Milwaukee, Lake Michigan)

Identification & Site Information

• Name: Unknown
• Type of Ship: Tugboat
• Location: Approximately 190 feet (58 metres) below the surface, off the coast of Milwaukee, Wisconsin, in Lake Michigan.
• Discovery Status: The wreck remains unidentified, with ongoing efforts to determine its origin and history.

Wreck Description

The Tugboat rests in 190 feet of water, a depth suitable only for advanced technical divers using trimix gas mixtures or remotely operated vehicles (ROVs).

Hull Condition: Appears largely intact, with some signs of degradation due to age and environmental factors. Wooden and metal structural components suggest a build date likely between the late 19th and early 20th centuries, a period of high Tugboat activity in the Great Lakes.

Key Features:  Potential remains of a steam engine or early diesel machinery, depending on the Tug’s construction period.  Evidence of towing equipment, such as winches, cables, and bollards.

Potential Historical Context

Tugboats were vital to Great Lakes maritime operations, providing essential services such as:

• Towing: Assisting freighters, barges, and sailing vessels through ports, narrow passages, and canals.
• Salvage Operations: Recovering vessels in distress or aiding during emergencies.
• •ndustrial Support: Moving construction materials and supporting breakwall or harbor projects.

Given Milwaukee’s active industrial port history, this Tug may have been involved in towing ships, construction work, or firefighting near the harbor.

Possible Origins

Without identification, several theories exist about the Tug’s history:

Storm Loss: The Tug may have been lost during a severe Lake Michigan storm, which frequently claimed vessels during the late 19th and early 20th centuries.

Collision or Accident: A common cause of Tugboat sinkings, especially in congested ports or while towing larger vessels.

Deliberate Scuttling: If no catastrophic event caused the sinking, the Tug might have been intentionally scuttled after being decommissioned.

Challenges in Identification

Efforts to identify the wreck are complicated by the following factors:

Lack of Documentation: Historical records of Tug losses may be incomplete or vague.

Environmental Factors: The cold, fresh waters of Lake Michigan help preserve wrecks, but sedimentation and biofouling may obscure identifying features like nameplates or registry markings.

Current Efforts

Exploration: The wreck has been documented using side-scan sonar and ROVs, capturing high-resolution imagery of the site.

Research: Historians and archaeologists are cross-referencing Tug losses near Milwaukee with the wreck’s observed characteristics.

Collaboration: Organizations like the Wisconsin Underwater Archeology Association and the Wisconsin Historical Society’s Maritime Archaeology Program are working to identify the Tug and learn more about its history.

Diving Information

• Depth: 190 feet (58 metres).
• Technical diving certification and experience with deep, cold-water dives.
• Visibility varies but is generally moderate to good in Lake Michigan’s clear waters.
• Divers should exercise caution due to the depth and potential entanglement hazards.

Significance

This unidentified Tug is a reminder of the unsung vessels that worked tirelessly to support Great Lakes shipping and harbor operations. Tugboats were indispensable to maritime commerce, and their crews often faced challenging and dangerous conditions.

Identifying this wreck would add a valuable piece to the puzzle of Milwaukee’s rich maritime history, shedding light on the Tug’s contributions and final moments.
