Paddling
Paddling Index methodology v1.0 · calculated 2026-09-16Tom Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, little nearby major-road exposure.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 41.3 of 43 | 96% natural land cover within 150 m of shore (94% forest, 2% wetland; 0% developed) |
| Geometric wind exposure | Excellent | 32.0 of 36 | mean fetch 566 m · 41% of sampled water within 500 m of shelter · short fetch in most directions |
| Motor & speed rules | Not modelled | — | Canada publishes vessel motor and speed restrictions as federal legal schedules, not map data, so they are not part of the Ontario index. Check local signage and Transport Canada rules before going out. |
| Public access | Not listed | — | No publicly listed MNRF fishing access point within 100 m of this shoreline. Municipal, private and informal launches are not all in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized. |
| Road isolation | Excellent | 21.4 of 21 | relatively isolated from major roads · 0 Ontario Road Network segments within 1.2 km (traffic estimated from road class, not measured) |
Additional paddling considerations
These describe the lake but are not part of the v1 Paddling Index and do not change the number above.
- Wake sensitivity
- Low — wide enough that wakes disperse over most of the lake
- Observed motorized activity
- Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
- Wildlife habitat potential
- High — 94% forest and 2% wetland cover within 150 m of shore
- Mapped wildlife habitat
- Mapped — Ontario MNRF has mapped moose aquatic feeding areas within 1 km of this lake. These are habitat records from provincial surveys, not animal counts; areas with nothing mapped may still hold wildlife. · Ontario MNRF Wildlife Values Area.

Tom Lake — common questions
How deep is Tom Lake?
The deepest contour on the Ontario MNRF bathymetric survey of Tom Lake is 34 m (112 ft). That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.
How big is Tom Lake?
Tom Lake covers about 58 ha (143 acres) in Kenora District, Ontario.
Is there public access to Tom Lake?
No fishing access point for Tom Lake appears in the Ontario MNRF fishing access point list (within 100 m of the shoreline). That is not the same as the lake being private -- the MNRF list is incomplete, and many municipal, marina and private launches are not in it.
