Survey readout
Eagle Lake is mapped to a depth of 35 ft on the Michigan DNR survey and covers about 380 acres in Cass 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 2026-08-21Eagle Lake has a substantially developed setting, moderate open-water exposure, substantial nearby higher-volume roads. Watercraft controls: Slow-no-wake zones.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Modest | 0.7 of 35 | 13% natural land cover within 150 m of shore (6% forest, 6% wetland; 75% developed) |
| Geometric wind exposure | Good | 13.6 of 29 | mean fetch 1,467 m · 0% of sampled water within 500 m of shelter · moderate open-water fetch |
| Watercraft controls | Slow-no-wake zones | 12.0 of 18 | Slow — no wake — designated zones only |
| 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 | Modest | 3.5 of 18 | substantial nearby higher-volume roads · 56 MDOT-classified segments within 1.2 km, peak 8,499 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
- Limited — 6% forest and 6% 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.
