Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Webb Lake has a heavily wooded and largely undeveloped 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 | Excellent | 32.2 of 35 | 88% natural land cover within 150 m of shore (39% forest, 49% wetland; 5% developed) |
| Geometric wind exposure | Excellent | 28.3 of 29 | mean fetch 497 m · 52% 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 | 14.4 of 18 | relatively isolated from major roads · 4 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
- Low — wide enough that wakes disperse over most of the lake
- Aquatic vegetation
- Low — approximately 1% 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 — 39% forest and 49% wetland cover within 150 m of shore
