Survey readout

Toivola Lakes is mapped to a depth of 40 ft on the Michigan DNR survey and covers about 16 acres in Houghton County, Michigan.

Measured from the Michigan DNR inland-lake contour survey.

Deepest sounding: 40 ft
Mean depth: 15.9 ft · estimated
Surface area: 16 acres
Estimated volume: 263 acre-ft · 86M gal
Shoreline: 0.8 mi · lobed
Aquatic vegetation: 21% of surface · NDVI estimate
Public access: No public DNR launch identified

Additional depth details8 contours

Contour depths: 0–40 ft
Recorded point soundings: 40 ft, 25 ft, 21 ft

17.3% of the surface sits over water shallower than 10 ft; 19.7% is deeper than 20 ft. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling

Paddling Index methodology v1.0 · calculated 2026-08-21

91 / 100ExcellentData confidence: Medium

Toivola Lakes has a heavily wooded and largely undeveloped setting, well sheltered geometry, little nearby major-road exposure. No special watercraft restriction is identified in the current source.

Why this score?5 components

Included in the index

Component	Rating	Points of weight	Measurement
Natural setting	Excellent	35.2 of 35	98% natural land cover within 150 m of shore (59% forest, 22% wetland; 0% developed)
Geometric wind exposure	Excellent	29.4 of 29	mean fetch 313 m · 100% of sampled water within 500 m of shelter · short fetch in most directions
Watercraft controls	None identified	8.8 of 18	No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law.
Public access	Not listed	—	No DNR-listed access site. Township, county and road-end launches are not in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized.
Road isolation	Excellent	17.6 of 18	relatively isolated from major roads · 0 MDOT-classified segments within 1.2 km

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: Moderate — narrow in places — wakes would carry across parts of the lake
Aquatic vegetation: Moderate — approximately 21% 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 — 59% forest and 22% 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 environmental, access, roadway and watercraft-control 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: natural setting 30%, geometric wind exposure 25%, watercraft controls 15%, public access 15%, road isolation 15%; observed motorboat activity is weighted 0% because no defensible lake-level measurement exists. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown. Sources: MI DNR Watercraft Control Areas (2026-08), USGS/MRLC NLCD Land Cover (2021), MDOT Annual Average Daily Traffic (2025) and MI DNR bathymetric survey outline (0 ft isobath). Conditions change quickly — check current weather and local conditions before going out.

Toivola Lakes — common questions

How deep is Toivola Lakes?

How big is Toivola Lakes?

Toivola Lakes covers about 16 acres in Houghton County, Michigan.

What is the average depth of Toivola Lakes?

The estimated mean depth of Toivola Lakes is 15.9 ft, calculated from the survey contours.

Is there public access to Toivola Lakes?

No public launch for Toivola Lakes appears in the Michigan DNR access data. That is not the same as the lake being private -- municipal and private ramps are not in that source.
