Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Silver Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, some nearby classified roads. 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 | 28.3 of 35 | 80% natural land cover within 150 m of shore (33% forest, 46% wetland; 10% developed) |
| Geometric wind exposure | Excellent | 25.8 of 29 | mean fetch 578 m · 29% 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 | Good | 10.7 of 18 | some nearby classified roads · 11 MDOT-classified segments within 1.2 km, peak 6,555 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
- Moderate — narrow in places — wakes would carry across parts 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
- High — 33% forest and 46% wetland cover within 150 m of shore

How deep is Silver Lake?
The deepest contour on the Michigan DNR bathymetric survey of Silver Lake is 20 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 Silver Lake?
Silver Lake covers about 45 acres in Mackinac County, Michigan.
What is the average depth of Silver Lake?
The estimated mean depth of Silver Lake is 6.5 ft, calculated from the survey contours.
Is there public access to Silver Lake?
No public launch for Silver 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.
