Wreck Location Map
Vessel Type
The Enterprise likely began life as a schooner named Couchiching (circa 1868), then was converted in about 1883 with the installation of twin-screw propulsion, becoming one of the few (or only) vessels on Lake Simcoe with dual propellers.
The refit may have included structural reinforcement and internal reconfiguration, but original plans or builder’s records are not located in the materials reviewed.
Contemporary and later sources refer to her as a steam excursion / passenger vessel, carrying people around the lake.
Description
The precise beam, draft, boiler/engine specs, and internal layout of the Enterprise remain undocumented in the sources reviewed.
History
The Enterprise served on Lake Simcoe in passenger and excursion service, linking Barrie, Jackson’s Point, and adjacent points, likely under local operators.
By August 1903, the vessel developed mechanical and pumping failure while en route from Big Bay Point toward Barrie (per local municipal record). Approaching Barrie, she was taking on water at a rate exceeding her pumps. The crew attempted to manage flooding and prevent water reaching the fire/boiler compartment. Unable to hold off the flooding, they pressed on to the Mulcaster Street wharf, where all aboard disembarked safely. Minutes later, the flooding overwhelmed the vessel, extinguished her steam, and she sank at the wharf.
According to Warren Lo Photography‘s narrative, after the sinking she was later refloated, sailed to Jackson’s Point, stripped of machinery, and deliberately scuttled in deeper water off Jackson’s Point.
Significant Incidents
- August 1903: The Enterprise sank at Barrie wharf due to mechanical failure and flooding.
- Post-sinking: The vessel was refloated, stripped of machinery, and scuttled off Jackson’s Point.
Final Disposition
The Enterprise did not suffer a catastrophic wreck by storm or collision. Rather, it succumbed due to mechanical failure and flooding. Her hull, after salvage of mechanical parts and equipment, was intentionally scuttled off Jackson’s Point, where submerged remains persist.
Current Condition & Accessibility
Access: shore / small boat from Jackson’s Point
Entry Point: Jackson’s Point harbour area or Malone Road wharf
Conditions: variable visibility, possible silt, shallow to moderate depths
Depth Range: unknown
Emergency Contacts: Canadian Coast Guard, Georgina township marine services
Permits: likely municipal / provincial approval required
Dive Support: local dive clubs in Simcoe / Georgina region

No casualties are recorded in the sinking or scuttling — all aboard reportedly evacuated safely. I did not locate crew lists, passenger manifests, or dedicated memorials in the sources examined. Newspaper archives (Barrie, Simcoe) may yet yield names and accounts.

Description
The *Enterprise* likely began life as a schooner named *Couchiching* (circa 1868), then was converted in about 1883 with the installation of twin‑screw propulsion, becoming one of the few (or only) vessels on Lake Simcoe with dual propellers.
The refit may have included structural reinforcement and internal reconfiguration, but I did not locate original plans or builder’s records in the materials reviewed.
Contemporary and later sources refer to her as a steam excursion / passenger vessel, carrying people around the lake.
Her precise beam, draft, boiler/engine specs, and internal layout remain undocumented in the sources I’ve reviewed.
History
The *Enterprise* served on Lake Simcoe in passenger and excursion service, linking Barrie, Jackson’s Point, and adjacent points, likely under local operators.
By August 1903, the vessel developed mechanical and pumping failure while en route from Big Bay Point toward Barrie (per local municipal record). :contentReference[oaicite:12]{index=12}
Approaching Barrie, she was taking on water at a rate exceeding her pumps. The crew attempted to manage flooding and prevent water reaching the fire/boiler compartment. Unable to hold off the flooding, they pressed on to the Mulcaster Street wharf, where all aboard disembarked safely. Minutes later, the flooding overwhelmed the vessel, extinguished her steam, and she sank at the wharf.
According to *Warren Lo Photography*’s narrative, after the sinking she was later refloated, sailed to Jackson’s Point, stripped of machinery, and deliberately scuttled in deeper water off Jackson’s Point.
A municipal planning document notes: “1903 – Steamer ENTERPRISE left for Jackson’s Point … the machinery is to be removed.”
Final Dispositions
The *Enterprise* did not suffer a catastrophic wreck by storm or collision. Rather, it succumbed due to mechanical failure and flooding.
Her hull, after salvage of mechanical parts and equipment, was intentionally scuttled off Jackson’s Point, where submerged remains persist.
Local walking-tour and heritage materials emphasize that the submerged marine railway and associated submerged structures remain visible in certain conditions.
Located By & Date Found
According to the *Warren Lo Photography* account, diver Scott Williamson located the remains in 1998.
Diving forums note that some wreck fragments have been found ~350‑450 ft offshore from Jackson’s Point, though the exact location is withheld or contested.
One forum post mentions that the location may be held secret due to heritage protection.
Notmars & Advisories
I found no evidence that the wreck is marked on navigational charts or issued formal navigational warnings (NOTMAR).
Given its location in near harbour waters, local authorities or heritage agencies likely control access.
In the municipal archive file, the Jackson’s Point marine railway is recognized as part of heritage infrastructure.

Crew & Casualty Memorials

Documented Statements & Extracts
“In 1903, the Steamer ENTERPRISE left for Jackson’s Point … the machinery is to be removed.” — *Barrie Northern Advance* (quoting municipal planning record)
“Originally built in 1868 as an 89‑foot schooner and named the *Couchiching*, the vessel was converted in 1883 by adding twin‑screw propellers. At Mulcaster Street wharf in Barrie, it sank in 1903. It was later refloated, sailed to Jackson’s Point, stripped, and scuttled.” — *Warren Lo photography / Lake Simcoe Living*
Registry, Enrollment & Insurance Trails
I did *not* locate a registry or formal enrollment record for *Enterprise / Couchiching* in the sources reviewed.
The municipal archive file does cite a local newspaper (Barrie Northern Advance) referencing removal of machinery post‑1903 sinking.
Because inland water vessel registries for smaller craft in that era were less formal, registry documentation may reside in county / provincial archives (Simcoe County, Ontario Archives).
Insurance records (if they existed) were not found in the surveyed dip of materials.
Site Documentation & Imaging
No published survey, mapping, or 3D imaging of the wreck site was found in the sources reviewed.
The submerged marine railway structure at Jackson’s Point is documented in municipal heritage files and appears in local walking tour descriptions as visible under spring water conditions.
The *Lake Simcoe Living* PDF lists the wreck among known lakebed vessels and references Williamson’s find.
