Wreck Location Map
Vessel Type
Vessel Type
Dump scows, also known as clutter barges, are utility vessels designed for carrying dredged material or debris.
Description
Description
This hull is relatively intact, with bow and stern framing providing good structure for mapping. Wooden scuppers are evident along the sides, common in scows designed for dredging operations. The vessel is positioned upright in shallow water and is likely scuttled intentionally as part of historical harbor clearance.
History
History
The construction date of this dump scow is not determined, but it is suggested that the hull construction features mortise-and-tenon plank joints, possibly indicating early 20th-century origins. The absence of deck structures and the hull rib structure suggest mid-1900s construction. Evidence of internal charring near midships may indicate post-scuttling burning, potentially linked to harbor removal techniques.

Summary & Significance
These two unregistered wooden scows represent a neglected segment of maritime history—utility vessels used for local harbor maintenance or dredging operations. Their scuttled graves off Thunder Bay offer an opportunity to study practical working craft of the early-to-mid 20th century, rather than commercial sailing vessels. Though they remain undocumented, disciplined documentation can provide insight into regional industrial practices and the lifecycle of utility hulls.
