Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 11.6 of 35 | 52% natural land cover within 150 m of shore (13% forest, 35% wetland; 38% developed) |
| Geometric wind exposure | Mixed | 6.8 of 29 | mean fetch 2,589 m · 0% of sampled water within 500 m of shelter · long fetch in some 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. |

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 — 13% forest and 35% wetland cover within 150 m of shore
- Mapped wildlife habitat
- Mapped — Ontario MNRF has mapped deer wintering area and waterfowl staging or nursery 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.

Bass Lake — common questions
How deep is Bass Lake?
The deepest contour on the Ontario MNRF bathymetric survey of Bass Lake is 9 m (30 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 Bass Lake?
Bass Lake covers about 550 ha (1,359 acres) in Simcoe County, Ontario.
Is there public access to Bass Lake?
The Ontario MNRF lists 1 fishing access point within 100 m of the shoreline of Bass Lake: 1 boat launch. Recorded ownership: 1 provincial. 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.
