Cedar Lake depth map
Cedar Lake in DeKalb County, Indiana reaches a depth of 25 feet. Cedar Lake is charted here across 8 closed depth contours, from the 2 ft line down to 25 ft, enclosing about 744 acres of water. Half of that water lies inside the 10 ft line, and only 3.9 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 |
|---|---|---|
| 2 ft | 744 acres | 100% |
| 4 ft | 683 acres | 92% |
| 6 ft | 603 acres | 81% |
| 8 ft | 435 acres | 59% |
| 10 ft | 260 acres | 35% |
| 12 ft | 76 acres | 10% |
| 20 ft | 14 acres | 1.9% |
| 25 ft | 3.9 acres | under 1% |
Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 744 acres inside the outermost charted contour (the 2 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 Cedar Lake: an evenly graded bottom
The survey encloses about 744 acres of Cedar Lake inside its 2 ft contour, and half of that water lies inside the 10 ft line, so the bottom falls away at a steady rate rather than shelving off or dropping in one step. Between 10 and 12 ft the mapped water sheds 184 acres in 2 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. 3.9 acres, under 1% of the mapped water, lie inside the deepest 25 ft contour, toward the northeastern corner of the lake. Topping out at 25 ft, weed growth structures this water more than depth does, but the 3.9-acre deep spot still concentrates fish in the heat of summer, and the one-contour depressions on the chart are the ones most anglers row straight over.
Ice fishing on Cedar Lake
A shallow lake like Cedar Lake is usually among the first to make safe ice, and once the weed beds die back the fish have very little deep water to spread into: just 3.9 acres inside the 25 ft contour. Start there, then hunt the subtle single-contour depressions across the 744-acre basin. Check ice thickness locally before you walk out.
Cedar Lake depth map FAQs
- How deep is Cedar Lake?
- Cedar Lake reaches a maximum depth of 25 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 8 closed depth contours over about 744 acres, and half of that water sits inside the 10 ft line.
- Where is the deepest part of Cedar Lake?
- The deepest charted water on Cedar Lake lies inside the 25 ft contour, toward the northeastern corner of the lake. That contour encloses 3.9 acres, under 1% of the mapped water, so it is a small target on a big lake, the depth chart above gives the contour to line up on.
- How much of Cedar Lake is shallower than 10 feet?
- About half. The 10 ft contour encloses 260 acres of the roughly 744 acres inside the outer 2 ft line, so the other half of the water is shallower than 10 feet. The sharpest drop is between 10 and 12 feet, where the mapped water sheds 184 acres.
- How accurate is this Cedar 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.
