Paddling
Paddling Index methodology v1.0 · calculated 2026-09-21Dallas Lake has a mixed natural and developed setting, generally sheltered geometry, some nearby classified 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 | 9.0 of 35 | 41% natural land cover within 150 m of shore (1% forest, 39% wetland; 34% developed) |
| Geometric wind exposure | Very Good | 20.1 of 29 | mean fetch 891 m · 14% of sampled water within 500 m of shelter · generally short fetch |
| 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 | Good | 10.8 of 18 | some nearby classified roads · 2 INDOT-classified segments 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
- Low — wide enough that wakes disperse over most of the lake
- Aquatic vegetation
- Low — approximately 6% 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 39% 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.

Dallas Lake — common questions
How deep is Dallas Lake?
The deepest contour on the Indiana DNR bathymetric survey of Dallas Lake is 100 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 Dallas Lake?
Dallas Lake covers about 320 acres in LaGrange County, Indiana.
Is there public access to Dallas Lake?
No public launch for Dallas Lake is shown in the Indiana DNR's public access data. That is not the same as the lake being private -- municipal and private ramps are not in that source.
