Wall Lake depth map
Wall Lake in LaGrange County, Indiana reaches a depth of 30 feet. Wall Lake is charted here across 6 closed depth contours, from the 5 ft line down to 30 ft, enclosing about 91 acres of water. Half of that water lies inside the 20 ft line, and only 8.1 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

| Depth contour | Water inside it | Share of mapped water |
|---|---|---|
| 5 ft | 91 acres | 100% |
| 10 ft | 60 acres | 66% |
| 15 ft | 47 acres | 52% |
| 20 ft | 31 acres | 35% |
| 25 ft | 18 acres | 20% |
| 30 ft | 8.1 acres | 8.9% |
Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 91 acres inside the outermost charted contour (the 5 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 Wall Lake: steep sides for its size
Inside its outermost 5 ft contour the survey charts about 91 acres of Wall Lake, with the 20 ft line enclosing half of it, so depth comes quickly here, with no long shallow margin before the bottom drops away. The sharpest change on the chart is between 5 and 10 ft, where the mapped water loses 31 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 30 ft contour holds 8.1 acres, 8.9% of the mapped water, toward the southwestern corner of the lake. Nothing here reaches a true cold-water layer at 30 ft, so structure does the thermocline's work: the points and inside turns where the 5 and 10 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.
Ice fishing on Wall Lake
At 30 ft, Wall Lake is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 30 ft hole, 8.1 acres of it, at first light, then move up onto the 5–10 ft break as the sun gets up, and fish the flats inside the 20 ft line through the middle of the day. Check ice thickness locally before you walk out.
Wall Lake depth map FAQs
- How deep is Wall Lake?
- Wall Lake reaches a maximum depth of 30 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 91 acres, and half of that water sits inside the 20 ft line.
- Where is the deepest part of Wall Lake?
- The deepest charted water on Wall Lake lies inside the 30 ft contour, toward the southwestern corner of the lake. That contour encloses 8.1 acres, 8.9% 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 Wall Lake is shallower than 20 feet?
- About half. The 20 ft contour encloses 31 acres of the roughly 91 acres inside the outer 5 ft line, so the other half of the water is shallower than 20 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 31 acres.
- How accurate is this Wall 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.
