Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Roy Lake has a mostly natural, lightly developed setting, generally sheltered geometry, nearby higher-volume roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Very Good | 27.3 of 43 | 70% natural land cover within 150 m of shore (40% forest, 29% wetland; 26% developed) |
| Geometric wind exposure | Very Good | 20.2 of 36 | mean fetch 1,145 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 | Mixed | 6.7 of 21 | nearby higher-volume roads · 6 MnDOT-classified segments within 1.2 km, peak 15,964 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 12% 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 — 40% forest and 29% wetland cover within 150 m of shore

- Zebra MusselListed in 2010 because this water is connected to Gull (11-0305). The species has not necessarily been found in this lake.
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.

Roy Lake — common questions
How deep is Roy Lake?
The deepest contour on the Minnesota DNR bathymetric survey of Roy Lake is 25 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 Roy Lake?
Roy Lake covers about 319 acres in Crow Wing County, Minnesota.
What fish are in Roy Lake?
Species with survey, catch or recent-stocking evidence include largemouth bass, northern pike, walleye, black crappie, bluegill, bowfin. The page lists all 14 species and the evidence behind each.
Is there public access to Roy Lake?
No public launch for Roy 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.
