Paddling
Paddling Index methodology v1.0 · calculated 2026-10-08Barr Lake has a mixed natural and developed setting, well sheltered geometry, little nearby major-road exposure. 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 | 9.0 of 35 | 28% natural land cover within 150 m of shore (12% forest, 6% wetland; 6% developed) |
| Geometric wind exposure | Excellent | 29.4 of 29 | mean fetch 379 m · 93% of sampled water within 500 m of shelter · short fetch in most directions |
| Watercraft controls | None identified | 8.8 of 18 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |
| 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 | Excellent | 17.6 of 18 | relatively isolated from major roads · 1 INDOT-classified segment within 1.2 km, peak 425 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
- Moderate — narrow in places — wakes would carry across parts of the lake
- Aquatic vegetation
- Moderate — approximately 19% 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 — 12% forest and 6% wetland cover within 150 m of shore

The deepest contour on the Indiana DNR bathymetric survey of Barr Lake is 41 ft. That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.
How big is Barr Lake?
Barr Lake covers about 25 acres in Fulton County, Indiana.
Is there public access to Barr Lake?
