Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Haymarsh Lakes has a heavily wooded and largely undeveloped setting, generally sheltered geometry, some nearby classified roads. 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 | 31.0 of 35 | 87% natural land cover within 150 m of shore (56% forest, 26% wetland; 6% developed) |
| Geometric wind exposure | Very Good | 20.1 of 29 | mean fetch 875 m · 8% 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 | Good | 9.0 of 18 | some nearby classified roads · 13 MDOT-classified segments within 1.2 km, peak 636 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
- High — approximately 70% 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 — 56% forest and 26% wetland cover within 150 m of shore
