How deep is Monocle Lake?

Monocle Lake is more than 55 feet deep. The deepest contour in the Michigan DNR Inland Lake Contours survey is the 55 foot line, and the lake continues deeper inside it.

Where is the deepest part of Monocle Lake?

The deepest charted water on Monocle Lake lies inside the 55 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 Monocle Lake is shallower than 25 feet?

About half. The 25 ft contour encloses 55 acres of the roughly 116 acres inside the outer 10 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 27 acres.

How accurate is this Monocle 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.

Monocle Lake depth map

Monocle Lake in Chippewa County, Michigan reaches a depth of more than 55 feet at its deepest surveyed contour. Monocle Lake is charted here across 10 closed depth contours, from the 10 ft line down to 55 ft, enclosing about 116 acres of water. Half of that water lies inside the 25 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.

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 116 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 Monocle Lake: an evenly graded bottom

The survey encloses about 116 acres of Monocle Lake inside its 10 ft contour, and half of that water lies inside the 25 ft line, so the bottom falls away at a steady rate rather than shelving off or dropping in one step. Between 15 and 20 ft the mapped water sheds 27 acres in 5 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. The 55 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 55 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 15 and 20 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Ice fishing on Monocle Lake

Monocle Lake's 55 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 55 ft hole, all 0.2 acres of it; as the sun gets up, move onto the 15–20 ft break, and spend the middle of the day on the flats inside the 25 ft line. Check ice thickness locally before you walk out.
