How deep is Troy-cedar Lake?

Troy-cedar Lake reaches a maximum depth of 80 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 8 closed depth contours over about 71 acres, and half of that water sits inside the 30 ft line.

Where is the deepest part of Troy-cedar Lake?

The deepest charted water on Troy-cedar Lake lies inside the 80 ft contour, toward the western side of the lake. That contour encloses 2.1 acres, 3% 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 Troy-cedar Lake is shallower than 30 feet?

About half. The 30 ft contour encloses 32 acres of the roughly 71 acres inside the outer 10 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 10 and 20 feet, where the mapped water sheds 23 acres.

How accurate is this Troy-cedar 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.

Troy-cedar Lake depth map

Troy-cedar Lake in Whitley County, Indiana reaches a depth of 80 feet. Troy-cedar Lake is charted here across 8 closed depth contours, from the 10 ft line down to 80 ft, enclosing about 71 acres of water. Half of that water lies inside the 30 ft line, and only 2.1 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Troy-cedar Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
10 ft	71 acres	100%
20 ft	48 acres	68%
30 ft	32 acres	46%
40 ft	20 acres	29%
50 ft	15 acres	21%
60 ft	11 acres	16%
70 ft	6.9 acres	9.8%
80 ft	2.1 acres	3%

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 71 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 Troy-cedar Lake: a wide shallow flat over a deep hole

Inside its outermost 10 ft contour the survey charts about 71 acres of Troy-cedar Lake, with the 30 ft line enclosing half of it, so the bulk of this Whitley County water sits on a shallow flat, with the real depth packed into one part of the basin. The sharpest change on the chart is between 10 and 20 ft, where the mapped water loses 23 acres in 10 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 80 ft contour holds 2.1 acres, 3% of the mapped water, toward the western side of the lake. 80 ft of water makes this a two-story fishery: warm-water fish hold the 10-to-30 ft ground while the basin can stay cold below the summer thermocline, and the traffic between the two runs along the 10–20 ft break at first and last light.

Ice fishing on Troy-cedar Lake

Troy-cedar Lake freezes later and less evenly than the shallow waters around it, and the winter bite sets up on the first real break rather than out over the 80 ft hole. The 10–20 ft band on the chart above is that edge: 23 acres of bottom tilt away there, and panfish and walleye slide up and down it through the day. Late ice pushes fish back onto the 10-to-30 ft flat. Check ice thickness locally before you walk out.
