Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Spring Lake has a heavily wooded and largely undeveloped setting, generally sheltered geometry, little nearby major-road exposure.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 39.3 of 43 | 91% natural land cover within 150 m of shore (88% forest, 4% wetland; 0% developed) |
| Geometric wind exposure | Very Good | 22.4 of 36 | mean fetch 988 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 | 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 | Excellent | 21.4 of 21 | 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 1% 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 — 88% forest and 4% 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.

Spring Lake — common questions
How deep is Spring Lake?
The deepest contour on the Minnesota DNR bathymetric survey of Spring Lake is 60 ft. That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.
How big is Spring Lake?
Spring Lake covers about 219 acres in St. Louis County, Minnesota.
What fish are in Spring Lake?
Species with survey, catch or recent-stocking evidence include lake trout, lake whitefish, largemouth bass, northern pike, smallmouth bass, green sunfish. The page lists all 10 species and the evidence behind each.
Is there public access to Spring Lake?
No public launch for Spring Lake appears in the Minnesota DNR access data. That is not the same as the lake being private -- private and commercial launches are not in that source.
