How deep is Walloon Lake?

Walloon Lake is more than 100 feet deep. The deepest contour in the Michigan DNR Inland Lake Contours survey is the 100 foot line, and the lake continues deeper inside it.

Where is the deepest part of Walloon Lake?

The deepest charted water on Walloon Lake lies inside the 90 ft contour, toward the northwestern corner of the lake. That contour encloses 13 acres, under 1% of the mapped water, so it is a small target on a big lake, the depth chart above gives the contour to line up on.

How much of Walloon Lake is shallower than 20 feet?

About half. The 20 ft contour encloses 2,058 acres of the roughly 4,505 acres inside the outer 5 ft line, so the other half of the water is shallower than 20 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 1,345 acres.

How accurate is this Walloon 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.

Walloon Lake depth map

Walloon Lake in Emmet County, Michigan reaches a depth of more than 100 feet at its deepest surveyed contour. Walloon Lake is charted here across 10 closed depth contours, from the 5 ft line down to 90 ft, enclosing about 4,505 acres of water. Half of that water lies inside the 20 ft line, and only 13 acres 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 4,505 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. The survey also records a 94 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Walloon Lake: a wide shallow flat over a deep hole

The survey encloses about 4,505 acres of Walloon Lake inside its 5 ft contour, and half of that water lies inside the 20 ft line, so the bulk of this Emmet County water sits on a shallow flat, with the real depth packed into one part of the basin. Between 5 and 10 ft the mapped water sheds 1,345 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 deepest 90 ft contour holds 13 acres, under 1% of the mapped water, toward the northwestern corner of the lake. 100 ft of water makes this a two-story fishery: warm-water fish hold the 5-to-20 ft ground while the basin can stay cold below the summer thermocline, and the traffic between the two runs along the 5–10 ft break at first and last light.

Ice fishing on Walloon Lake

Walloon 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 90 ft hole. The 5–10 ft band on the chart above is that edge: 1,345 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 5-to-20 ft flat. Check ice thickness locally before you walk out.
