Paddling
Paddling Index methodology v1.0 · calculated 2026-09-25Ham Lake has a mostly natural, lightly developed setting, well sheltered geometry, some nearby classified roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Very Good | 31.8 of 43 | 78% natural land cover within 150 m of shore (52% forest, 22% wetland; 20% developed) |
| Geometric wind exposure | Excellent | 35.7 of 36 | mean fetch 439 m · 78% of sampled water within 500 m of shelter · short fetch in most 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 | Good | 12.8 of 21 | some nearby classified roads · 1 MnDOT-classified segment within 1.2 km, peak 1,124 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
- High — 52% forest and 22% 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.

Ham Lake — common questions
How deep is Ham Lake?
The deepest contour on the Minnesota DNR bathymetric survey of Ham Lake is 20 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 Ham Lake?
Ham Lake covers about 42 acres in Morrison County, Minnesota.
What fish are in Ham Lake?
Species with survey, catch or recent-stocking evidence include largemouth bass, northern pike, black bullhead, black crappie, bluegill, bowfin. The page lists all 12 species and the evidence behind each.
Is there public access to Ham Lake?
