Survey readout
Stone Lake has a reported maximum depth of 43 ft, and covers about 203 acres in LaPorte 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. Coverage is sparse: about 56% of this lake lies well away from any surveyed contour, so most of the shape shown there is interpolated between distant measurements rather than mapped. Depths come from the Indiana DNR survey of 2017.
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.

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
- Limited — 27% forest and 12% 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.

Stone Lake — common questions
How deep is Stone Lake?
The Indiana DNR reports a maximum depth of 43 ft for Stone 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 Stone Lake?
Stone Lake covers about 203 acres in LaPorte County, Indiana.
What fish are in Stone Lake?
Species with survey, catch or recent-stocking evidence include channel catfish, largemouth bass, black crappie, bluegill, bowfin, brown bullhead. The page lists all 18 species and the evidence behind each.
Is there public access to Stone Lake?
Yes. The Indiana DNR lists a public access site on Stone Lake: a boat ramp with restrooms and ADA access. The DNR records no fee. DNR directions: "Located in Laporte, off Lakeshore Dr., Pine-564 acres, Stone-140 acres."
Is the depth of Stone 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.
