Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Lake Elmo has a mixed natural and developed setting, moderate open-water exposure, substantial nearby higher-volume roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 14.0 of 35 | 51% natural land cover within 150 m of shore (38% forest, 13% wetland; 26% developed) |
| Geometric wind exposure | Good | 15.0 of 29 | mean fetch 1,321 m · 2% 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 | 2 DNR public access sites · boat ramp · fishing pier |
| Road isolation | Modest | 3.2 of 18 | substantial nearby higher-volume roads · 16 MnDOT-classified segments within 1.2 km, peak 10,028 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 10% 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 — 38% forest and 13% 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.
