Emma Lake depth map
Emma Lake in LaGrange County, Indiana reaches a depth of 30 feet. Emma Lake is charted here across 4 closed depth contours, from the 15 ft line down to 30 ft, enclosing about 22 acres of water. Half of that water lies inside the 25 ft line, and only 1.9 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 |
|---|---|---|
| 15 ft | 22 acres | 100% |
| 20 ft | 13 acres | 59% |
| 25 ft | 7.5 acres | 34% |
| 30 ft | 1.9 acres | 8.4% |
Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 22 acres inside the outermost charted contour (the 15 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 Emma Lake: steep sides for its size
Inside its outermost 15 ft contour the survey charts about 22 acres of Emma Lake, with the 25 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 15 and 20 ft, where the mapped water loses 9 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 1.9 acres, 8.4% 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 15 and 20 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.
Ice fishing on Emma Lake
At 30 ft, Emma 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, 1.9 acres of it, at first light, then move up onto the 15–20 ft break as the sun gets up, and fish the flats inside the 25 ft line through the middle of the day. Check ice thickness locally before you walk out.
Emma Lake depth map FAQs
- How deep is Emma Lake?
- Emma Lake reaches a maximum depth of 30 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 4 closed depth contours over about 22 acres, and half of that water sits inside the 25 ft line.
- Where is the deepest part of Emma Lake?
- The deepest charted water on Emma Lake lies inside the 30 ft contour, toward the southwestern corner of the lake. That contour encloses 1.9 acres, 8.4% 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 Emma Lake is shallower than 25 feet?
- About half. The 25 ft contour encloses 7.5 acres of the roughly 22 acres inside the outer 15 ft line, so the other half of the water is shallower than 25 feet. The sharpest drop is between 15 and 20 feet, where the mapped water sheds 9 acres.
- How accurate is this Emma 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.
