Survey readout
Royer Lake has a reported maximum depth of 57 ft, and covers about 73 acres in LaGrange County, Indiana. The Indiana DNR survey maps contours down to 50 ft; the depth between 50 ft and 57 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 50 ft is interpolated. The survey's own contours stop at 50 ft, while it reports a maximum of 57 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 2026-09-21Royer Lake has a mixed natural and developed setting, well sheltered geometry, little nearby major-road exposure. Watercraft controls: Speed limit.

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 7% 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 — 1% forest and 42% wetland cover within 150 m of shore

Fishing rules for this lake Beta
Size and daily limits for the 16 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.
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.

Royer Lake — common questions
How deep is Royer Lake?
The Indiana DNR reports a maximum depth of 57 ft for Royer 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 Royer Lake?
Royer Lake covers about 73 acres in LaGrange County, Indiana.
What fish are in Royer Lake?
Species with survey, catch or recent-stocking evidence include channel catfish, largemouth bass, walleye, black crappie, bluegill, bowfin. The page lists all 16 species and the evidence behind each.
Is there public access to Royer Lake?
The Indiana DNR lists Royer Lake as open to the public by water rather than from a ramp of its own: its access record reads "Royer Lake (boat ramp on Fish Lake)". The launch is on connected water, not on Royer Lake itself.
Is the depth of Royer Lake measured or estimated?
The survey contours reach 50 ft while the survey reports a maximum of 57 ft, so the basin between those depths is inferred by the model rather than measured.
