Paddling Index methodology v1.0 · calculated 2026-09-21JI Case Lake has a mostly natural, lightly developed setting, well sheltered geometry, nearby higher-volume roads. Watercraft controls: Electric motors only.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Very Good | 20.0 of 30 | 73% natural land cover within 150 m of shore (65% forest, 6% wetland; 17% developed) |
| Geometric wind exposure | Excellent | 22.9 of 25 | mean fetch 543 m · 40% 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 · fishing pier |
| Road isolation | Mixed | 4.5 of 15 | nearby higher-volume roads · 4 INDOT-classified segments within 1.2 km, peak 13,665 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 8% 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 — 65% forest and 6% wetland cover within 150 m of shore
