Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Marion Lake has a mostly natural, lightly developed setting, generally sheltered geometry, limited nearby major-road exposure. Watercraft controls: Restricted hours.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Very Good | 26.1 of 35 | 76% natural land cover within 150 m of shore (55% forest, 20% wetland; 13% developed) |
| Geometric wind exposure | Very Good | 16.9 of 29 | mean fetch 1,121 m · 0% of sampled water within 500 m of shelter · generally short fetch |
| Watercraft controls | Restricted hours | 10.9 of 18 | Restricted hours |
| 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 | Very Good | 11.2 of 18 | limited nearby major-road exposure · 13 MDOT-classified segments within 1.2 km, peak 1,321 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 12% 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 — 55% forest and 20% wetland cover within 150 m of shore
