Survey readout
Fish Lake has a reported maximum depth of 82 ft, and covers about 102 acres in LaGrange County, Indiana. The Indiana DNR survey maps contours down to 70 ft; the depth between 70 ft and 82 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 70 ft is interpolated. The survey's own contours stop at 70 ft, while it reports a maximum of 82 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 2026-09-21Fish Lake has a mixed natural and developed setting, generally sheltered geometry, limited nearby major-road exposure. No special watercraft restriction is identified in the current source.

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 — 4% forest and 36% wetland cover within 150 m of shore

Fishing rules for this lake Beta
Size and daily limits for the 18 species found here — 14 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.
From 312 IAC 9-7 (Sport fishing), Indiana Administrative Code (readopted 2025-03-25), and the 2026-2027 Indiana Fishing Regulations Guide · verified 2026-09-15. Regulations can change — the Indiana Administrative Code (312 IAC 9-7) is the controlling source; verify current regulations before fishing. Official regulations

How to identify invasive species in Indiana lakes →
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.

Fish Lake — common questions
How deep is Fish Lake?
The Indiana DNR reports a maximum depth of 82 ft for Fish Lake. The survey's own contours reach 70 ft, so the depth below that is interpolated from the reported maximum rather than mapped.
How big is Fish Lake?
Fish Lake covers about 102 acres in LaGrange County, Indiana.
What fish are in Fish Lake?
Species with survey, catch or recent-stocking evidence include channel catfish, largemouth bass, walleye, black crappie, bluegill, bowfin. The page lists all 18 species and the evidence behind each.
Is there public access to Fish Lake?
Yes. The Indiana DNR lists a public access site on Fish Lake: a boat ramp with ADA access. DNR directions: "Two miles south of Plato off CR 500E."
Is the depth of Fish Lake measured or estimated?
The survey contours reach 70 ft while the survey reports a maximum of 82 ft, so the basin between those depths is inferred by the model rather than measured.
