Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Ball Bluff Lake has a heavily wooded and largely undeveloped setting, generally sheltered geometry, limited nearby major-road exposure.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 31.6 of 35 | 87% natural land cover within 150 m of shore (33% forest, 52% wetland; 7% developed) |
| Geometric wind exposure | Very Good | 19.5 of 29 | mean fetch 906 m · 0% of sampled water within 500 m of shelter · generally short fetch |
| 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 | Good | 15.0 of 18 | 1 DNR public access site · boat ramp |
| Road isolation | Very Good | 11.2 of 18 | limited nearby major-road exposure · 2 MnDOT-classified segments within 1.2 km, peak 1,184 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 2% 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 — 33% forest and 52% wetland cover within 150 m of shore

Infested waters listing
Not on the Minnesota DNR’s infested waters list as of September 9, 2026. This does not mean the lake is free of invasive species: the list covers certain species only, and a species can be present before anyone finds it.
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.
