Paddling
Paddling Index methodology v1.0 · calculated 2026-09-23Spring Mill Pond has a mixed natural and developed setting, well sheltered geometry, limited 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 | Mixed | 13.9 of 35 | 49% natural land cover within 150 m of shore (0% forest, 31% wetland; 22% developed) |
| Geometric wind exposure | Excellent | 29.4 of 29 | mean fetch 221 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 | Very Good | 13.3 of 18 | limited nearby major-road exposure · 3 MDOT-classified segments within 1.2 km, peak 3,465 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
- High — narrow throughout — passing wakes would reach most of the water
- Aquatic vegetation
- Low — approximately 3% 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 — 0% forest and 31% wetland cover within 150 m of shore

What does non-native mean?
USGS records identify non-native species that have been documented for this lake or its shoreline. Non-native does not necessarily mean invasive, and historical records do not confirm current presence.
