Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Brule Lake has a heavily wooded and largely undeveloped setting, long open-water fetch, little nearby major-road exposure.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 33.1 of 35 | 92% natural land cover within 150 m of shore (76% forest, 16% wetland; 0% developed) |
| Geometric wind exposure | Modest | 1.5 of 29 | mean fetch 5,351 m · 1% of sampled water within 500 m of shelter · long 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 | Excellent | 17.6 of 18 | 1 DNR public access site · carry-in or canoe launch |
| Road isolation | Excellent | 17.6 of 18 | relatively isolated from major roads · 0 MnDOT-classified segments within 1.2 km |
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 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 — 76% forest and 16% wetland cover within 150 m of shore
- Wilderness
- Inside the BWCAW — This lake lies inside the Boundary Waters Canoe Area Wilderness. Federal wilderness rules apply: visitor permits are required, and motors are allowed only on certain lakes, with horsepower limits. Check Superior National Forest rules before going. · MN DNR BWCAW boundary (Public Law 95-495)

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.
