Survey readout
Island Lake is mapped to a depth of 60 ft on the Michigan DNR survey and covers about 110 acres in Schoolcraft 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 2026-08-21Island Lake has a heavily wooded and largely undeveloped setting, generally sheltered geometry, little nearby major-road exposure. Watercraft controls: Restricted hours.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Excellent | 25.1 of 30 | 84% natural land cover within 150 m of shore (59% forest, 24% wetland; 7% developed) |
| Geometric wind exposure | Very Good | 18.6 of 25 | mean fetch 744 m · 0% of sampled water within 500 m of shelter · generally short fetch |
| Watercraft controls | Restricted hours | 9.3 of 15 | Restricted hours |
| Public access | Good | 12.8 of 15 | 1 site with DNR boating-facility records · 1 ramp lane · 8 trailer spaces |
| Road isolation | Excellent | 13.9 of 15 | relatively isolated from major roads · 10 MDOT-classified segments within 1.2 km, peak 1,036 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
- High — 59% forest and 24% wetland cover within 150 m of shore

How big is Island Lake?
Island Lake covers about 110 acres in Schoolcraft County, Michigan.
What is the average depth of Island Lake?
The estimated mean depth of Island Lake is 17.3 ft, calculated from the survey contours.
What fish are in Island Lake?
Species with survey, catch or recent-stocking evidence include largemouth bass, smallmouth bass, bluegill. The page shows the evidence behind each.
Is there public access to Island Lake?
