31 / 100ModestData confidence: High

Cannon Lake has a substantially developed setting, notable open-water exposure, substantial nearby higher-volume roads.

Why this score?5 components

Included in the index

Component	Rating	Points of weight	Measurement
Natural setting	Modest	5.9 of 35	31% natural land cover within 150 m of shore (12% forest, 18% wetland; 32% developed)
Geometric wind exposure	Mixed	6.7 of 29	mean fetch 2,606 m · 0% 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	Good	15.0 of 18	3 DNR public access sites · boat ramp · fishing pier
Road isolation	Modest	2.9 of 18	substantial nearby higher-volume roads · 14 MnDOT-classified segments within 1.2 km, peak 9,145 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 0% 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 — 12% forest and 18% wetland cover within 150 m of shore
State water trail: On a state water trail — Part of a designated Minnesota State Water Trail: Cannon River. · MN DNR State Water Trails

Compare Minnesota lakes by Paddling Index →

How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public land-cover, access and traffic-count data. It is not a user review, a safety rating, or a prediction of an individual outing. Differences of a few points should not be treated as meaningful — an 84 and an 82 are broadly comparable. Components and weights for Minnesota lakes: natural setting 35%, geometric wind exposure 29%, public access 18%, road isolation 18%. Motor, speed and no-wake rules are not modeled for Minnesota, and traffic counts cover state, county and some city roads but not township roads. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown. Minnesota scores are relative to other Minnesota lakes and are not directly comparable with Paddling Index scores on our sister sites, which use different data sources, some with a watercraft-rules component. Sources: MN DNR lake bathymetry outline, USGS/MRLC NLCD Land Cover (2021), MN DNR Water Access Sites and Fishing Piers & Shore Fishing Sites (2026-09) and MnDOT Annual Average Daily Traffic (counts 2021–2025). Conditions change quickly — check current weather and local conditions before going out.

How to identify invasive species in Minnesota lakes →

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.
