Royer Lake depth map

Royer Lake in LaGrange County, Indiana reaches a depth of 50 feet. Royer Lake is charted here across 5 closed depth contours, from the 10 ft line down to 50 ft, enclosing about 52 acres of water. Half of that water lies inside the 30 ft line, and only 2.7 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 52 acres inside the outermost charted contour (the 10 ft line), which is the outer edge of the mapped water, several state files carry no 0 ft shoreline line, so this is not the same as a share of the lake's published surface area.

Fishing Royer Lake: an evenly graded bottom

About 52 acres of Royer Lake sit inside the survey's 10 ft contour, and half of that water is already gone by the 30 ft line: the bottom falls away at a steady rate rather than shelving off or dropping in one step. The steepest break on the chart runs from 20 down to 30 ft: 16 acres of bottom fall away across 10 ft there, which makes that band the first contour to work. 2.7 acres, 5.1% of the mapped water, lie inside the deepest 50 ft contour, toward the southwestern corner of the lake. With 50 ft at its deepest there is no true cold-water layer here, so structure does the work the thermocline does elsewhere: fish the points and inside turns where the 20 and 30 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Ice fishing on Royer Lake

Royer Lake's 50 ft is a workable ice depth, enough water to hold fish all winter, without the slow freeze-up of a big basin. First light belongs on the 50 ft hole, all 2.7 acres of it; as the sun gets up, move onto the 20–30 ft break, and spend the middle of the day on the flats inside the 30 ft line. Check ice thickness locally before you walk out.

Royer Lake depth map FAQs

How deep is Royer Lake?
Royer Lake reaches a maximum depth of 50 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 5 closed depth contours over about 52 acres, and half of that water sits inside the 30 ft line.
Where is the deepest part of Royer Lake?
The deepest charted water on Royer Lake lies inside the 50 ft contour, toward the southwestern corner of the lake. That contour encloses 2.7 acres, 5.1% of the mapped water, so it is a small target on a small water, the depth chart above gives the contour to line up on.
How much of Royer Lake is shallower than 30 feet?
About half. The 30 ft contour encloses 22 acres of the roughly 52 acres inside the outer 10 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 20 and 30 feet, where the mapped water sheds 16 acres.
How accurate is this Royer Lake depth map?
The contours come from the Indiana DNR Lake Bathymetry survey, retrieved August 2026 and last rebuilt on August 19, 2026. Depths change over time with water levels and sediment, so treat this map as a planning guide for fishing, and never use it for navigation. Per Indiana DNR, the data are graphical representations for reference only, not a survey instrument. Acreages are computed from the published contour geometry, not from a separate area survey, so read them as close approximations.
