Survey readout
Williams Lake has a reported maximum depth of 43 ft, and covers about 50 acres in Noble County, Indiana. The Indiana DNR survey maps contours down to 40 ft; the depth between 40 ft and 43 ft is interpolated rather than measured. Depths come from the Indiana DNR survey of 2019.
Measured from the Indiana DNR lake bathymetry survey.
Depth below 40 ft is interpolated. The survey's own contours stop at 40 ft, while it reports a maximum of 43 ft. The basin between those two depths is inferred by the model, not measured — so the shape of the deep hole is an estimate, and the deep-spot marker shows the deepest depth actually surveyed.

Paddling
Paddling Index methodology v1.0 · calculated 2026-09-21Williams Lake has a partly natural setting, well sheltered geometry, little nearby major-road exposure. No special watercraft restriction is identified in the current source.
Why this score?5 components

| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Good | 15.3 of 30 | 54% natural land cover within 150 m of shore (17% forest, 38% wetland; 16% developed) |
| Geometric wind exposure | Excellent | 25.0 of 25 | mean fetch 419 m · 92% of sampled water within 500 m of shelter · short fetch in most directions |
| Watercraft controls | None identified | 7.5 of 15 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |

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 5% 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 — 17% forest and 38% wetland cover within 150 m of shore

Fishing rules for this lake Beta
Size and daily limits for the 15 species found here — 12 open to harvest.
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.

Williams Lake — common questions
How deep is Williams Lake?
The Indiana DNR reports a maximum depth of 43 ft for Williams Lake. The survey's own contours reach 40 ft, so the depth below that is interpolated from the reported maximum rather than mapped.
How big is Williams Lake?
Williams Lake covers about 50 acres in Noble County, Indiana.
What fish are in Williams Lake?
Species with survey, catch or recent-stocking evidence include largemouth bass, northern pike, black crappie, bluegill, brown bullhead, pumpkinseed. The page lists all 15 species and the evidence behind each.
Is there public access to Williams Lake?
Yes. The Indiana DNR lists a public access site on Williams Lake: a boat ramp with a boat dock, restrooms and ADA access. The DNR records no fee.
Is the depth of Williams Lake measured or estimated?
The survey contours reach 40 ft while the survey reports a maximum of 43 ft, so the basin between those depths is inferred by the model rather than measured.
