Paddling
Paddling Index methodology v1.0 · calculated 2026-09-16Potter Lake has a heavily wooded and largely undeveloped setting, generally sheltered geometry, little nearby major-road exposure.
On a canoe route · portages mapped. Portage trails end at this shoreline, including Brule Lake - Potter Lake Portage. Portages carry canoes over land between waters, and the ground around the lake in the 3D view is terrain those trails cross. Trail condition, length and elevation change are not measured here — check the park or canoe-route map before you go. Trails: OpenStreetMap (ODbL).
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 41.4 of 43 | 96% natural land cover within 150 m of shore (89% forest, 7% wetland; 1% developed) |
| Geometric wind exposure | Very Good | 21.2 of 36 | mean fetch 1,092 m · 7% of sampled water within 500 m of shelter · generally short fetch |
| 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 — 89% forest and 7% 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.

Potter Lake — common questions
How deep is Potter Lake?
The deepest contour on the Ontario MNRF bathymetric survey of Potter Lake is 14 m (46 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 Potter Lake?
Potter Lake covers about 93 ha (231 acres) in Nipissing District, Ontario.
Is there public access to Potter Lake?
No fishing access point for Potter Lake appears in the Ontario MNRF fishing access point list (within 100 m of the shoreline), but Potter Lake lies inside Algonquin Provincial Park (Ontario Parks), which runs its own facilities and is not covered by that data. Check with the park for launch details.
