How deep is Oliver Lake?

Oliver Lake reaches a maximum depth of 80 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 8 closed depth contours over about 266 acres, and half of that water sits inside the 60 ft line.

Where is the deepest part of Oliver Lake?

The deepest charted water on Oliver Lake lies inside the 80 ft contour, toward the middle of the lake. That contour encloses 35 acres, 13% 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 Oliver Lake is shallower than 60 feet?

About half. The 60 ft contour encloses 131 acres of the roughly 266 acres inside the outer 10 ft line, so the other half of the water is shallower than 60 feet. The sharpest drop is between 70 and 80 feet, where the mapped water sheds 65 acres.

How accurate is this Oliver 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.

Oliver Lake depth map

Oliver Lake in LaGrange County, Indiana reaches a depth of 80 feet. Oliver Lake is charted here across 8 closed depth contours, from the 10 ft line down to 80 ft, enclosing about 266 acres of water. Half of that water lies inside the 60 ft line, and only 35 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Oliver Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
10 ft	266 acres	100%
20 ft	248 acres	93%
30 ft	225 acres	85%
40 ft	199 acres	75%
50 ft	162 acres	61%
60 ft	131 acres	49%
70 ft	100 acres	38%
80 ft	35 acres	13%

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 266 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 Oliver Lake: steep walls and a big basin

The survey encloses about 266 acres of Oliver Lake inside its 10 ft contour, and half of that water lies inside the 60 ft line, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. Between 70 and 80 ft the mapped water sheds 65 acres in 10 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. 35 acres, 13% of the mapped water, lie inside the deepest 80 ft contour, toward the middle of the lake. At 80 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 10-to-60 ft ground, and the fish that move between the two do it along the 70–80 ft break at first and last light.

Ice fishing on Oliver Lake

Deep water like Oliver Lake freezes later and less evenly than the shallow lakes around it, and the winter bite sets up on the first real break, not out over the 80 ft hole. That edge is the 70–80 ft band on the chart above, where 65 acres of bottom tilt away, and panfish and walleye work up and down it through the day. By late ice the fish push back onto the 10-to-60 ft flat. Check ice thickness locally before you walk out.
