69 / 100MixedData confidence: High

Lake Netta 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	25.1 of 35	75% natural land cover within 150 m of shore (22% forest, 53% wetland; 20% developed)
Geometric wind exposure	Very Good	23.9 of 29	mean fetch 648 m · 10% 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	Good	15.0 of 18	1 DNR public access site · boat ramp
Road isolation	Mixed	5.4 of 18	nearby higher-volume roads · 16 MnDOT-classified segments within 1.2 km, peak 7,519 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: Moderate — approximately 16% 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 — 22% forest and 53% wetland cover within 150 m of shore

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.

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

Lake Netta — common questions

How deep is Lake Netta?

The deepest contour on the Minnesota DNR bathymetric survey of Lake Netta is 15 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 Lake Netta?

Lake Netta covers about 119 acres in Anoka County, Minnesota.

Is there public access to Lake Netta?

Yes. The Minnesota DNR lists a public access site on Lake Netta: a boat ramp. It is administered by City of Ham Lake. DNR directions: "Gladys Landborg Jones Park 169th Avenue NE to Xylite Street NE."
