Ferdinand State Forest Lake depth map
Ferdinand State Forest Lake in Dubois County, Indiana reaches a depth of 20 feet. Ferdinand State Forest Lake is charted here across 10 closed depth contours, from the 2 ft line down to 20 ft, enclosing about 34 acres of water. Half of that water lies inside the 10 ft line, and only under an acre 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 34 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 Ferdinand State Forest Lake: an evenly graded bottom
About 34 acres of Ferdinand State Forest Lake sit inside the survey's 2 ft contour, and half of that water is already gone by the 10 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 2 down to 4 ft: 5 acres of bottom fall away across 2 ft there, which makes that band the first contour to work. The 20 ft contour, toward the southeastern corner of the lake, encloses under an acre of water, a single pocket rather than a basin, but one worth a drift over in high summer. Topping out at 20 ft, weed growth structures this water more than depth does, but the 0.1-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.
Ferdinand State Forest Lake depth map FAQs
- How deep is Ferdinand State Forest Lake?
- Ferdinand State Forest Lake reaches a maximum depth of 20 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 10 closed depth contours over about 34 acres, and half of that water sits inside the 10 ft line.
- Where is the deepest part of Ferdinand State Forest Lake?
- The deepest charted water on Ferdinand State Forest Lake lies inside the 20 ft contour, toward the southeastern corner of the lake. That contour encloses under an acre, under 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 Ferdinand State Forest Lake is shallower than 10 feet?
- About half. The 10 ft contour encloses 17 acres of the roughly 34 acres inside the outer 2 ft line, so the other half of the water is shallower than 10 feet. The sharpest drop is between 2 and 4 feet, where the mapped water sheds 5 acres.
- How accurate is this Ferdinand State Forest 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.
