Paddling

Paddling Index methodology v1.0 · calculated 2026-09-25
85 / 100Very GoodData confidence: High

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

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 6% 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 — 65% forest and 20% 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 (counts 2022–2025). 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.

Quick answers

Harriet Lake — common questions

How deep is Harriet Lake?

The deepest contour on the Minnesota DNR bathymetric survey of Harriet Lake is 30 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 Harriet Lake?

Harriet Lake covers about 258 acres in Lake County, Minnesota.

What fish are in Harriet Lake?

Species with survey, catch or recent-stocking evidence include northern pike, walleye, black crappie, yellow perch, white sucker. The page shows the evidence behind each.

Is there public access to Harriet Lake?

Yes. The Minnesota DNR lists a public access site on Harriet Lake: a boat ramp with restrooms. It is administered by the U.S. Forest Service. DNR directions: "Approximately 20 mi N of Finland on Cnty Rd 7, then 0.5 mi N on Forest Rd to S shore."
