Mullett Lake depth map
Mullett Lake in Cheboygan County, Michigan reaches a depth of 120 feet. Mullett Lake is charted here across 13 closed depth contours, from the 5 ft line down to 120 ft, enclosing about 16,630 acres of water. Half of that water lies inside the 40 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 16,630 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 Mullett Lake: a stepped drop into deep water
The survey encloses about 16,630 acres of Mullett Lake inside its 5 ft contour, and half of that water lies inside the 40 ft line, so the bottom steps down contour by contour into the deep basin rather than shelving flat or plunging all at once. Between 5 and 10 ft the mapped water sheds 2,357 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 120 ft contour, toward the southwestern corner 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. At 120 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 5-to-40 ft ground, and the fish that move between the two do it along the 5–10 ft break at first and last light.
Ice fishing on Mullett Lake
Deep water like Mullett Lake freezes later and less evenly than the shallow lakes around it, and the winter bite sets up on the first real break, not out over the 120 ft hole. That edge is the 5–10 ft band on the chart above, where 2,357 acres of bottom tilt away, and panfish and walleye work up and down it through the day. By late ice the fish push back onto the 5-to-40 ft flat. Check ice thickness locally before you walk out.
Mullett Lake depth map FAQs
- How deep is Mullett Lake?
- Mullett Lake reaches a maximum depth of 120 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 13 closed depth contours over about 16,630 acres, and half of that water sits inside the 40 ft line.
- Where is the deepest part of Mullett Lake?
- The deepest charted water on Mullett Lake lies inside the 120 ft contour, toward the southwestern corner of the lake. That contour encloses under an acre, 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 Mullett Lake is shallower than 40 feet?
- About half. The 40 ft contour encloses 7,429 acres of the roughly 16,630 acres inside the outer 5 ft line, so the other half of the water is shallower than 40 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 2,357 acres.
- How accurate is this Mullett 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.
