| Geometric wind exposure | Excellent | 25.0 of 25 | mean fetch 460 m · 71% of sampled water within 500 m of shelter · short fetch in most directions |
| Watercraft controls | Electric motors only | 14.2 of 15 | Electric motors only |
| Public access | Good | 12.8 of 15 | 1 DNR fishing access site · boat ramp · ADA-accessible · fishing pier |
| Road isolation | Excellent | 14.6 of 15 | relatively isolated from major roads · 3 INDOT-classified segments within 1.2 km, peak 1,001 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 12% 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 — 78% forest and 4% wetland cover within 150 m of shore
