How deep is Lake Manitou?

Lake Manitou 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 473 acres, and half of that water sits inside the 15 ft line.

Where is the deepest part of Lake Manitou?

The deepest charted water on Lake Manitou lies inside the 45 ft contour, toward the eastern side 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 Lake Manitou is shallower than 15 feet?

About half. The 15 ft contour encloses 212 acres of the roughly 473 acres inside the outer 5 ft line, so the other half of the water is shallower than 15 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 213 acres.

How accurate is this Lake Manitou 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.

Lake Manitou depth map

Lake Manitou in Fulton County, Indiana reaches a depth of 45 feet. Lake Manitou is charted here across 9 closed depth contours, from the 5 ft line down to 45 ft, enclosing about 473 acres of water. Half of that water lies inside the 15 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.

Lake Manitou depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
5 ft	473 acres	100%
10 ft	260 acres	55%
15 ft	212 acres	45%
20 ft	168 acres	36%
25 ft	122 acres	26%
30 ft	90 acres	19%
35 ft	54 acres	12%
40 ft	21 acres	4.4%
45 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 473 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 Lake Manitou: a broad shallow flat

Inside its outermost 5 ft contour the survey charts about 473 acres of Lake Manitou, with the 15 ft line enclosing half of it, so most of this Fulton County water is shallow and the depth is concentrated in one part of the basin. The sharpest change on the chart is between 5 and 10 ft, where the mapped water loses 213 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The 45 ft contour, toward the eastern side 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. 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 5 and 10 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Ice fishing on Lake Manitou

Lake Manitou'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 0.4 acres of it; as the sun gets up, move onto the 5–10 ft break, and spend the middle of the day on the flats inside the 15 ft line. Check ice thickness locally before you walk out.
