Survey readout
Rosser Park Pond has a reported maximum depth of 31 ft, and covers about 36 acres in Lake County, Indiana. The Indiana DNR survey maps contours down to 18 ft; the depth between 18 ft and 31 ft is interpolated rather than measured. Depths come from the Indiana DNR survey of 2018.
Measured from the Indiana DNR lake bathymetry survey.
Depth below 18 ft is interpolated. The survey's own contours stop at 18 ft, while it reports a maximum of 31 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
- Moderate — narrow in places — wakes would carry across parts of the lake
- Aquatic vegetation
- Low — approximately 1% 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 — 4% forest and 13% wetland cover within 150 m of shore

Fishing rules for this lake Beta
Size and daily limits for the 16 species found here — 11 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.

Regulations can change — the Indiana Administrative Code (312 IAC 9-7) is the controlling source; verify current regulations before fishing. Official regulations

Rosser Park Pond — common questions
How deep is Rosser Park Pond?
The Indiana DNR reports a maximum depth of 31 ft for Rosser Park Pond. The survey's own contours reach 18 ft, so the depth below that is interpolated from the reported maximum rather than mapped.
How big is Rosser Park Pond?
Rosser Park Pond covers about 36 acres in Lake County, Indiana.
What fish are in Rosser Park Pond?
Species with survey, catch or recent-stocking evidence include channel catfish, largemouth bass, black crappie, bluegill, bowfin, brown bullhead. The page lists all 16 species and the evidence behind each.
Is there public access to Rosser Park Pond?
Yes. The Indiana DNR lists a public access site on Rosser Park Pond: a boat ramp with restrooms. The DNR records no fee.
Is the depth of Rosser Park Pond measured or estimated?
The survey contours reach 18 ft while the survey reports a maximum of 31 ft, so the basin between those depths is inferred by the model rather than measured.
