Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Stuart Lake has a heavily wooded and largely undeveloped setting, generally 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 | 32.6 of 35 | 89% natural land cover within 150 m of shore (48% forest, 42% wetland; 4% developed) |
| Geometric wind exposure | Very Good | 24.4 of 29 | mean fetch 632 m · 19% of sampled water within 500 m of shelter · generally short fetch |
| 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 · 1 MDOT-classified segment within 1.2 km, peak 287 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 2% 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 — 48% forest and 42% wetland cover within 150 m of shore

Stuart Lake — common questions
How deep is Stuart Lake?
The deepest contour on the Michigan DNR bathymetric survey of Stuart Lake is 23 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 Stuart Lake?
Stuart Lake covers about 75 acres in Luce County, Michigan.
What is the average depth of Stuart Lake?
The estimated mean depth of Stuart Lake is 12.8 ft, calculated from the survey contours.
Is there public access to Stuart Lake?
No public launch for Stuart 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.
