|---|---|---|---|
| Natural setting | Very Good | 20.2 of 30 | 71% natural land cover within 150 m of shore (43% forest, 28% wetland; 16% developed) |
| Geometric wind exposure | Good | 9.6 of 25 | mean fetch 1,777 m · 0% of sampled water within 500 m of shelter · moderate 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. |
| Public access | Good | 12.8 of 15 | 1 site with DNR boating-facility records · 1 ramp lane · 8 trailer spaces |

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
- High — 43% forest and 28% 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.
