Paddling
Paddling Index methodology v1.0 · calculated 2026-09-16Rankin Lake has a mixed natural and developed setting, generally sheltered geometry, substantial nearby higher-volume roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 11.9 of 35 | 51% natural land cover within 150 m of shore (47% forest, 1% wetland; 48% developed) |
| Geometric wind exposure | Very Good | 19.5 of 29 | mean fetch 931 m · 10% 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 | Good | 15.0 of 18 | 1 MNRF fishing access point · boat ramp |
| Road isolation | Modest | 3.6 of 18 | substantial nearby higher-volume roads · 103 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
- Limited — 47% forest and 1% wetland cover within 150 m of shore
- Mapped wildlife habitat
- Mapped — Ontario MNRF has mapped deer wintering area 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.

Rankin Lake — common questions
How deep is Rankin Lake?
The deepest contour on the Ontario MNRF bathymetric survey of Rankin Lake is 18.3 m (60 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 Rankin Lake?
Rankin Lake covers about 142 ha (351 acres) in Parry Sound District, Ontario.
Is there public access to Rankin Lake?
The Ontario MNRF lists 1 fishing access point within 100 m of the shoreline of Rankin Lake: 1 boat launch. Recorded ownership: 1 municipal. The list includes municipal and privately owned sites, and some may charge a fee or restrict parking, so it confirms a place anglers use rather than a public right of way. Check locally before you go.
