Paddling

Paddling Index methodology v1.0 · calculated 2026-09-25
89 / 100Very GoodData confidence: High

Shumway Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, little nearby major-road exposure.

Why this score?5 components

Included in the index

ComponentRatingPoints of weightMeasurement
Natural settingExcellent30.8 of 3587% natural land cover within 150 m of shore (60% forest, 26% wetland; 7% developed)

Motor & speed rulesNot 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.

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
High — 60% forest and 26% wetland cover within 150 m of shore
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 (current). Conditions change quickly — check current weather and local conditions before going out.

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.
