How deep is Dallas Lake?

Dallas Lake reaches a maximum depth of 100 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 10 closed depth contours over about 217 acres, and half of that water sits inside the 50 ft line.

Where is the deepest part of Dallas Lake?

The deepest charted water on Dallas Lake lies inside the 100 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 Dallas Lake is shallower than 50 feet?

About half. The 50 ft contour encloses 90 acres of the roughly 217 acres inside the outer 10 ft line, so the other half of the water is shallower than 50 feet. The sharpest drop is between 20 and 30 feet, where the mapped water sheds 42 acres.

How accurate is this Dallas 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.

Dallas Lake depth map

Dallas Lake in LaGrange County, Indiana reaches a depth of 100 feet. Dallas Lake is charted here across 10 closed depth contours, from the 10 ft line down to 100 ft, enclosing about 217 acres of water. Half of that water lies inside the 50 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.

Dallas Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
10 ft	217 acres	100%
20 ft	188 acres	87%
30 ft	146 acres	67%
40 ft	113 acres	52%
50 ft	90 acres	42%
60 ft	59 acres	27%
70 ft	40 acres	18%
80 ft	25 acres	12%
90 ft	10 acres	4.8%
100 ft	under 1 acre	under 1%

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 217 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 Dallas Lake: a stepped drop into deep water

Inside its outermost 10 ft contour the survey charts about 217 acres of Dallas Lake, with the 50 ft line enclosing half of it, so the bottom steps down contour by contour into the deep basin rather than shelving flat or plunging all at once. The sharpest change on the chart is between 20 and 30 ft, where the mapped water loses 42 acres in 10 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The 100 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. At 100 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-50 ft ground, and the fish that move between the two do it along the 20–30 ft break at first and last light.

Ice fishing on Dallas Lake

Deep water like Dallas 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 100 ft hole. That edge is the 20–30 ft band on the chart above, where 42 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-50 ft flat. Check ice thickness locally before you walk out.
