How deep is Bennett Lake?

Bennett Lake is at least 58 feet deep. That figure is the deepest surveyed sounding in the Michigan DNR Inland Lake Contours survey, a point measurement rather than a closed contour, so the deepest line you can actually trace on the map is the 50 ft contour, and the water may run deeper still.

Where is the deepest part of Bennett Lake?

The deepest charted water on Bennett Lake lies inside the 50 ft contour, toward the northwestern corner of the lake. That contour encloses 28 acres, 34% of the mapped water, so it is a broad slice of the bottom rather than a pinpoint target, the depth chart above gives the contour to line up on.

How much of Bennett Lake is shallower than 50 feet?

About half. The 50 ft contour encloses 28 acres of the roughly 84 acres inside the outer 10 ft line, so the other half of the water is shallower than 50 feet. The sharpest drop is between 40 and 50 feet, where the mapped water sheds 18 acres.

How accurate is this Bennett Lake depth map?

The contours come from the Michigan DNR Inland Lake Contours 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. Acreages are computed from the published contour geometry, not from a separate area survey, so read them as close approximations.

Bennett Lake depth map

Bennett Lake in Livingston County, Michigan reaches a depth of more than 58 feet at its deepest surveyed sounding. Bennett Lake is charted here across 5 closed depth contours, from the 10 ft line down to 50 ft, enclosing about 84 acres of water. Half of that water lies inside the 50 ft line, and only 28 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Bennett Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
10 ft	84 acres	100%
20 ft	72 acres	86%
30 ft	58 acres	69%
40 ft	46 acres	55%
50 ft	28 acres	34%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 84 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. The survey also records a 58 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Bennett Lake: steep sides for its size

About 84 acres of Bennett Lake sit inside the survey's 10 ft contour, and half of that water is already gone by the 50 ft line: depth comes quickly here, with no long shallow margin before the bottom drops away. The steepest break on the chart runs from 40 down to 50 ft: 18 acres of bottom fall away across 10 ft there, which makes that band the first contour to work. The deepest 50 ft contour holds 28 acres, 34% of the mapped water, toward the northwestern corner of the lake. Nothing here reaches a true cold-water layer at 58 ft, so structure does the thermocline's work: the points and inside turns where the 40 and 50 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Bennett Lake

At 58 ft, Bennett 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 50 ft hole, 28 acres of it, at first light, then move up onto the 40–50 ft break as the sun gets up, and fish the flats inside the 50 ft line through the middle of the day. Check ice thickness locally before you walk out.
