Other waters with a public launch on this map: Lake Huron. Their launches are not marked on the model — only Grand Lake’s own are.
57.2% of the surface sits over water shallower than 10 ft; 5.9% is deeper than 20 ft; the survey shows 2 distinct basins. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Grand Lake has a mixed natural and developed setting, long open-water fetch, substantial nearby higher-volume 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 | Mixed | 10.6 of 30 | 49% natural land cover within 150 m of shore (14% forest, 34% wetland; 30% developed) |
| Geometric wind exposure | Modest | 1.2 of 25 | mean fetch 5,029 m · 0% of sampled water within 500 m of shelter · long open-water fetch |
| Watercraft controls | None identified | 7.5 of 15 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |

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 9% 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 — 14% forest and 34% 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.
