Survey readout
Smoky Lake is mapped to a depth of 60 ft on the Michigan DNR survey and covers about 568 acres in Iron 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 2026-08-21Smoky Lake has a mostly natural, lightly developed setting, notable open-water exposure, limited 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 | Very Good | 24.0 of 35 | 70% natural land cover within 150 m of shore (56% forest, 14% wetland; 11% developed) |
| Geometric wind exposure | Mixed | 8.1 of 29 | mean fetch 2,308 m · 0% of sampled water within 500 m of shelter · long fetch in some 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 | Very Good | 11.9 of 18 | limited nearby major-road exposure · 4 MDOT-classified segments within 1.2 km, peak 231 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 4% 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 — 56% forest and 14% wetland cover within 150 m of shore

What does non-native mean?
USGS records identify non-native species that have been documented for this lake or its shoreline. Non-native does not necessarily mean invasive, and historical records do not confirm current presence.

Smoky Lake — common questions
How deep is Smoky Lake?
The deepest contour on the Michigan DNR bathymetric survey of Smoky Lake is 60 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 Smoky Lake?
Smoky Lake covers about 568 acres in Iron County, Michigan.
What is the average depth of Smoky Lake?
The estimated mean depth of Smoky Lake is 24.2 ft, calculated from the survey contours.
Is there public access to Smoky Lake?
No public launch for Smoky 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.
