Gentian/failing Lake depth map
Gentian/failing Lake in Steuben County, Indiana reaches a depth of 45 feet. Gentian/failing Lake is charted here across 9 closed depth contours, from the 5 ft line down to 45 ft, enclosing about 23 acres of water. Half of that water lies inside the 30 ft line, and only 2.5 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 | 23 acres | 100% |
| 10 ft | 21 acres | 92% |
| 15 ft | 19 acres | 85% |
| 20 ft | 18 acres | 80% |
| 25 ft | 15 acres | 66% |
| 30 ft | 11 acres | 49% |

| 40 ft | 4.4 acres | 19% |
| 45 ft | 2.5 acres | 11% |
Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 23 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 Gentian/failing Lake: steep sides for its size
The survey encloses about 23 acres of Gentian/failing Lake inside its 5 ft contour, and half of that water lies inside the 30 ft line, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. Between 30 and 35 ft the mapped water sheds 4.3 acres in 5 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. 2.5 acres, 11% of the mapped water, lie inside the deepest 45 ft contour, toward the southwestern corner of the lake. With 45 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 30 and 35 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.
Ice fishing on Gentian/failing Lake
Gentian/failing Lake's 45 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 45 ft hole, all 2.5 acres of it; as the sun gets up, move onto the 30–35 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.
Gentian/failing Lake depth map FAQs
- How deep is Gentian/failing Lake?
- Gentian/failing Lake reaches a maximum depth of 45 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 23 acres, and half of that water sits inside the 30 ft line.
- Where is the deepest part of Gentian/failing Lake?
- The deepest charted water on Gentian/failing Lake lies inside the 45 ft contour, toward the southwestern corner of the lake. That contour encloses 2.5 acres, 11% 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 Gentian/failing Lake is shallower than 30 feet?
- About half. The 30 ft contour encloses 11 acres of the roughly 23 acres inside the outer 5 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 30 and 35 feet, where the mapped water sheds 4.3 acres.
- How accurate is this Gentian/failing 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.
