Lake Simcoe Shipwrecks & Dive Sites

Lake Simcoe is one of Ontario’s most historic inland waterways — a cold, clear basin that
has hosted steamboats, schooners, barges, and ice traffic for nearly two centuries. While not as deep as the
Great Lakes, its consistently cold water preserves wooden wrecks extremely well, offering divers a distinct
inland view of early Ontario marine life.

Simcoe’s wrecks are accessible, beginner-friendly, and visually striking — especially in the spring and fall
when visibility peaks. It’s a training ground, a discovery zone, and a reminder that serious history exists
well beyond the big lakes.

The Shotline Diving Lake Simcoe Project combines wreck records, shore-access notes, and
historical research to give divers a practical, honest view of what the lake offers in all seasons.

Lake Simcoe Dive Highlights

Classic Inland Steamer Site

Type: Steamer / Passenger Vessel

Typical Depth: 10–18 m / 33–60 ft

Difficulty: Beginner–Intermediate

Representative of Simcoe’s early passenger and cargo traffic, with recognizable hull structure and
winter-ice history written into its story.

Training Barge & Workboat Remains

Type: Barge / Workboat Debris

Typical Depth: 6–12 m / 20–40 ft

Difficulty: Beginner

A forgiving site used for skills, buoyancy work, and early wreck orientation — proof that useful dives do
not have to be deep.

Ice-Season Curiosity Site

Type: Small Craft / Mixed Debris

Typical Depth: 8–14 m / 26–46 ft

Difficulty: Intermediate (conditions-dependent)

A site best appreciated outside peak boat-traffic months, where careful timing and conditions turn a quiet
patch of bottom into an excellent winter project.
