Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Tahquamenon Lake #3 has a heavily wooded and largely undeveloped setting, generally sheltered geometry, little nearby major-road exposure. No special watercraft restriction is identified in the current source.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 31.8 of 35 | 89% natural land cover within 150 m of shore (76% forest, 12% wetland; 0% developed) |
| Geometric wind exposure | Very Good | 24.5 of 29 | mean fetch 624 m · 15% of sampled water within 500 m of shelter · generally short fetch |
| Watercraft controls | None identified | 8.8 of 18 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |
| Public access | Not listed | — | No DNR-listed access site. Township, county and road-end launches are not 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 | 17.6 of 18 | relatively isolated from major roads · 2 MDOT-classified segments within 1.2 km, peak 24 vehicles/day |
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
- Aquatic vegetation
- Low — approximately 5% mapped coverage · NAIP aerial imagery (NDVI)
- 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 — 76% forest and 12% wetland cover within 150 m of shore
