Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Lake On-Three has a partly natural setting, well 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 | Good | 21.4 of 35 | 68% natural land cover within 150 m of shore (44% forest, 20% wetland; 28% developed) |
| Geometric wind exposure | Excellent | 29.4 of 29 | mean fetch 349 m · 100% of sampled water within 500 m of shelter · short fetch in most directions |
| 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 | 15.1 of 18 | relatively isolated from major roads · 6 MDOT-classified segments within 1.2 km, peak 117 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
- Moderate — narrow in places — wakes would carry across parts of the lake
- Aquatic vegetation
- Low — approximately 8% 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
- Moderate — 44% forest and 20% wetland cover within 150 m of shore
