Paddling
Paddling Index methodology v1.0 · calculated 2026-10-08Round Lake has a mixed natural and developed setting, well sheltered geometry, 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 | 12.1 of 35 | 47% natural land cover within 150 m of shore (1% forest, 47% wetland; 33% developed) |
| Geometric wind exposure | Excellent | 26.1 of 29 | mean fetch 569 m · 33% 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 | Modest | 3.7 of 18 | substantial nearby higher-volume roads · 22 INDOT-classified segments within 1.2 km, peak 14,624 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 16% 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 — 1% forest and 47% wetland cover within 150 m of shore

Fishing rules for this lake Beta
Size and daily limits for the 14 species found here — 8 open to harvest, 1 with a special rule or closed season.
These are hook-and-line size and daily limit rules. The fishing code sets no closed season for these species on inland lakes, but posted property rules can close a water — see the notes. Gear, spearing and bow fishing, netting and bait collection are set by other sections of 312 IAC 9 and are not shown here.
