Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Sand Point Lake has a partly natural setting, notable open-water exposure, little nearby major-road exposure.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Good | 21.3 of 43 | 49% natural land cover within 150 m of shore (44% forest, 5% wetland; 0% developed) |
| Geometric wind exposure | Mixed | 8.1 of 36 | mean fetch 2,631 m · 4% of sampled water within 500 m of shelter · long fetch in some directions |
| 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
- Limited — 44% forest and 5% wetland cover within 150 m of shore

Infested waters listing
1 confirmed, 1 via connectionMussels & snails
- Zebra MusselListed in 2025 because this water is connected to Namakan (69-0693). The species has not necessarily been found in this lake.
Other invertebrates
- Spiny WaterfleaConfirmed in this water in 2007 (listed 2007).
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.

Sand Point Lake — common questions
How deep is Sand Point Lake?
The deepest contour on the Minnesota DNR bathymetric survey of Sand Point Lake is 180 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 Sand Point Lake?
Sand Point Lake covers about 8,526 acres in St. Louis County, Minnesota.
What fish are in Sand Point Lake?
Species with survey, catch or recent-stocking evidence include burbot, lake whitefish, largemouth bass, northern pike, smallmouth bass, walleye. The page lists all 17 species and the evidence behind each.
Is there public access to Sand Point Lake?
No public launch for Sand Point 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.
