Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Syphon Lake 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 | 35.3 of 35 | 100% natural land cover within 150 m of shore (87% forest, 12% wetland; 0% developed) |
| Geometric wind exposure | Excellent | 29.4 of 29 | mean fetch 252 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 · 1 MDOT-classified segment within 1.2 km, peak 24 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 6% 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 — 87% forest and 12% wetland cover within 150 m of shore

How big is Syphon Lake?
Syphon Lake covers about 11 acres in Luce County, Michigan.
What is the average depth of Syphon Lake?
The estimated mean depth of Syphon Lake is 43.6 ft, calculated from the survey contours.
What fish are in Syphon Lake?
Species with survey, catch or recent-stocking evidence include brook trout. The page shows the evidence behind each.
Is there public access to Syphon Lake?
No public launch for Syphon 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.
