Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Good | 18.8 of 35 | 64% natural land cover within 150 m of shore (63% forest, 0% wetland; 34% developed) |
| Geometric wind exposure | Good | 11.9 of 29 | mean fetch 1,696 m · 0% of sampled water within 500 m of shelter · moderate open-water 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 | 2 MNRF fishing access points · boat ramp |
| Road isolation | Good | 10.5 of 18 | some nearby classified roads · 16 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
- Moderate — 63% forest and 0% wetland cover within 150 m of shore
- Mapped wildlife habitat
- Mapped — Ontario MNRF has mapped moose aquatic feeding 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.

Oliver Lake — common questions
How deep is Oliver Lake?
The deepest contour on the Ontario MNRF bathymetric survey of Oliver Lake is 36 m (118 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 Oliver Lake?
Oliver Lake covers about 195 ha (482 acres) in Thunder Bay District, Ontario.
Is there public access to Oliver Lake?
The Ontario MNRF lists 2 fishing access points within 100 m of the shoreline of Oliver Lake: 2 boat launches. 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.
