Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Duck Lake has a mixed natural and developed setting, moderate open-water exposure, limited nearby major-road exposure.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 13.1 of 35 | 50% natural land cover within 150 m of shore (49% forest, 1% wetland; 36% developed) |
| Geometric wind exposure | Good | 15.2 of 29 | mean fetch 1,296 m · 0% of sampled water within 500 m of shelter · moderate open-water 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 | 13.0 of 18 | limited nearby major-road exposure · 2 MnDOT-classified segments within 1.2 km, peak 342 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
- Limited — 49% forest and 1% 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.
