Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25South Little Long Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, some nearby classified roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 40.7 of 43 | 92% natural land cover within 150 m of shore (56% forest, 36% wetland; 2% developed) |
| Geometric wind exposure | Excellent | 35.7 of 36 | mean fetch 304 m · 100% of sampled water within 500 m of shelter · short fetch in most directions |
| Motor & speed rules | Not modeled | — | Minnesota’s lake-by-lake motor, speed and no-wake rules are mostly county and city ordinances, not map data, so they are not part of the Minnesota index. Check local signage and ordinances before going out. |
| Public access | Not listed | — | No public access site of this lake’s own in the MN DNR water access and fishing site records. Private, commercial and informal launches are not all in these records, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized. |
| Road isolation | Good | 12.0 of 21 | some nearby classified roads · 2 MnDOT-classified segments within 1.2 km, peak 1,894 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
- Moderate — narrow in places — wakes would carry across parts of the lake
- Aquatic vegetation
- Low — approximately 5% 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 36% wetland cover within 150 m of shore

What does the infested waters list mean?
The Minnesota DNR lists a lake, river, pond or wetland as infested when it contains an aquatic invasive species that could spread to other waters, or when it is connected to a water where one is present. Activities such as bait harvest and water use are managed differently on infested waters. Check the current list before moving water, bait or equipment.
