Survey readout
School Section Lake is mapped to a depth of 33 ft on the Michigan DNR survey and covers about 132 acres in Mecosta County, Michigan.
Measured from the Michigan DNR inland-lake contour survey (depths read from the survey's isobath field; this lake's summary-depth column is blank in the source).

Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21School Section Lake has a mixed natural and developed setting, generally sheltered geometry, nearby higher-volume roads. Watercraft controls: Restricted hours.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 12.1 of 35 | 50% natural land cover within 150 m of shore (34% forest, 14% wetland; 36% developed) |
| Geometric wind exposure | Very Good | 22.1 of 29 | mean fetch 758 m · 16% of sampled water within 500 m of shelter · generally short fetch |
| Watercraft controls | Restricted hours | 10.9 of 18 | Restricted hours |
| 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 | Mixed | 6.1 of 18 | nearby higher-volume roads · 23 MDOT-classified segments within 1.2 km, peak 2,635 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 10% 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 — 34% forest and 14% wetland cover within 150 m of shore
