The lake

Survey readout

Witmer Lake has a reported maximum depth of 55 ft, and covers about 238 acres in LaGrange County, Indiana. The Indiana DNR survey maps contours down to 50 ft; the depth between 50 ft and 55 ft is interpolated rather than measured. Depths come from the Indiana DNR survey of 2013.

Measured from the Indiana DNR lake bathymetry survey.

Depth below 50 ft is interpolated. The survey's own contours stop at 50 ft, while it reports a maximum of 55 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.

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 3% 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.

How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public environmental, access, roadway and watercraft-control data. It is not a user review, a safety rating, or a prediction of an individual outing. Differences of a few points should not be treated as meaningful — an 84 and an 82 are broadly comparable. Components and weights: natural setting 30%, geometric wind exposure 25%, watercraft controls 15%, public access 15%, road isolation 15%; observed motorboat activity is weighted 0% because no defensible lake-level measurement exists. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown.

Fishing rules for this lake Beta

Size and daily limits for the 20 species found here — 15 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.

Black CrappieOpen to harvestMinimum size: no size limit · Daily limit: 25 (312 IAC 9-7-14(a)) Black and white crappie together.
BluegillOpen to harvestMinimum size: no size limit · Daily limit: no limit (312 IAC 9-7-14(d) · “Bluegill”)
Beta. This panel is newly published. Every value is transcribed from the Indiana Administrative Code (312 IAC 9-7) and checked against the Indiana DNR's 2026-27 Fishing Regulations Guide, but the coverage and wording are still under review. If anything here disagrees with 312 IAC 9-7 or the Indiana DNR's guide, the DNR is right — the Administrative Code is the legal text; the guide summarizes it.
No closed season in the fishing code: 312 IAC 9-7 sets no season for these species on inland lakes (trout and salmon “at any time of year”, 9-7-13(d)(1)). Posted property rules can still close a water or bar entry (312 IAC 8-2-1) and 312 IAC 9-6-6 closes a few named areas, so check the property before you go. The possession limit is twice the daily bag limit (312 IAC 9-1-12.1); fish already processed and stored at your primary residence do not count toward it (312 IAC 9-2-8(d)).

Plants & algae

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.

Quick answers

Witmer Lake — common questions

How deep is Witmer Lake?

The Indiana DNR reports a maximum depth of 55 ft for Witmer Lake. The survey's own contours reach 50 ft, so the depth below that is interpolated from the reported maximum rather than mapped.

How big is Witmer Lake?

Witmer Lake covers about 238 acres in LaGrange County, Indiana.

What fish are in Witmer Lake?

Species with survey, catch or recent-stocking evidence include channel catfish, largemouth bass, black crappie, bluegill, bowfin, brown bullhead. The page lists all 20 species and the evidence behind each.

Is there public access to Witmer Lake?

Yes. The Indiana DNR lists a public access site on Witmer Lake: a boat ramp with restrooms and ADA access. The DNR records no fee. DNR directions: "At Wolcottville from SR 9, 1 mile west on CR 800S."

Is the depth of Witmer Lake measured or estimated?

The survey contours reach 50 ft while the survey reports a maximum of 55 ft, so the basin between those depths is inferred by the model rather than measured.
