Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Ruppert Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, limited nearby major-road exposure. Watercraft controls: Whole-lake slow-no-wake.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 30.0 of 30 | 95% natural land cover within 150 m of shore (2% forest, 93% wetland; 3% developed) |
| Geometric wind exposure | Excellent | 25.0 of 25 | mean fetch 345 m · 100% of sampled water within 500 m of shelter · short fetch in most directions |
| Watercraft controls | Whole-lake slow-no-wake | 13.8 of 15 | Slow — no wake |
| Public access | Good | 12.8 of 15 | 1 site with DNR boating-facility records · 1 ramp lane · 6 trailer spaces |
| Road isolation | Very Good | 11.0 of 15 | limited nearby major-road exposure · 4 MDOT-classified segments within 1.2 km, peak 676 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 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
- High — 2% forest and 93% wetland cover within 150 m of shore
