Paddling
Paddling Index methodology v1.0 · calculated 2026-09-16Tarpaper 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 | 34.9 of 35 | 99% natural land cover within 150 m of shore (96% forest, 0% wetland; 0% developed) |
| Geometric wind exposure | Excellent | 29.4 of 29 | mean fetch 362 m · 100% 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 | Good | 12.3 of 18 | 1 MNRF fishing access point · shoreline access |
| Road isolation | Excellent | 17.6 of 18 | relatively isolated from major roads · 1 Ontario Road Network segment 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
- Moderate — narrow in places — wakes would carry across parts 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 — 96% forest and 0% wetland cover within 150 m of shore
- Mapped wildlife habitat
- Mapped — Ontario MNRF has mapped moose aquatic feeding area and 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.

Is there public access to Tarpaper Lake?
The Ontario MNRF lists 1 fishing access point within 100 m of the shoreline of Tarpaper Lake: 1 shoreline access site. 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.
