Survey readout

Little Stony Lake is mapped to a depth of 27 ft on the Michigan DNR survey and covers about 51 acres in Lenawee County, Michigan.

Measured from the Michigan DNR inland-lake contour survey.

Deepest sounding: 27 ft
Mean depth: 11.7 ft · estimated
Surface area: 51 acres
Estimated volume: 598 acre-ft · 195M gal
Shoreline: 1.14 mi · round
Aquatic vegetation: 3% of surface · NDVI estimate
Public access: No public DNR launch identified

Additional depth details6 contours

Contour depths: 0–27 ft
Recorded point soundings: 27 ft

37.1% of the surface sits over water shallower than 10 ft; 13.6% 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 Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.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

72 / 100GoodData confidence: Medium

Little Stony Lake has a partly natural setting, well sheltered geometry, some nearby classified roads. Watercraft controls: High-speed boating prohibited.

Why this score?5 components

Included in the index

Component	Rating	Points of weight	Measurement
Natural setting	Good	18.5 of 35	61% natural land cover within 150 m of shore (24% forest, 36% wetland; 23% developed)
Geometric wind exposure	Excellent	29.4 of 29	mean fetch 469 m · 67% of sampled water within 500 m of shelter · short fetch in most directions
Watercraft controls	High-speed boating prohibited	15.0 of 18	High-speed boating prohibited
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	Good	8.9 of 18	some nearby classified roads · 11 MDOT-classified segments within 1.2 km, peak 6,483 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 3% 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: Moderate — 24% forest and 36% 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).

Quick answers

Little Stony Lake — common questions

How deep is Little Stony Lake?

The deepest contour on the Michigan DNR bathymetric survey of Little Stony Lake is 27 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 Little Stony Lake?

Little Stony Lake covers about 51 acres in Lenawee County, Michigan.

What is the average depth of Little Stony Lake?

The estimated mean depth of Little Stony Lake is 11.7 ft, calculated from the survey contours.

Is there public access to Little Stony Lake?

No public launch for Little Stony Lake 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.
