Lake Michigamme depth map
Lake Michigamme in Marquette County, Michigan reaches a depth of 70 feet. Lake Michigamme is charted here across 14 closed depth contours, from the 5 ft line down to 70 ft, enclosing about 4,347 acres of water. Half of that water lies inside the 40 ft line, and only 24 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 4,347 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 Lake Michigamme: a stepped drop into deep water
The survey encloses about 4,347 acres of Lake Michigamme 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 50 and 55 ft the mapped water sheds 551 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. 24 acres, under 1% of the mapped water, lie inside the deepest 70 ft contour, toward the northeastern corner of the lake. At 70 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 50–55 ft break at first and last light.
Ice fishing on Lake Michigamme
Deep water like Lake Michigamme 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 70 ft hole. That edge is the 50–55 ft band on the chart above, where 551 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.
Lake Michigamme depth map FAQs
- How deep is Lake Michigamme?
- Lake Michigamme reaches a maximum depth of 70 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 14 closed depth contours over about 4,347 acres, and half of that water sits inside the 40 ft line.
- Where is the deepest part of Lake Michigamme?
- The deepest charted water on Lake Michigamme lies inside the 70 ft contour, toward the northeastern corner of the lake. That contour encloses 24 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 Lake Michigamme is shallower than 40 feet?
- About half. The 40 ft contour encloses 1,883 acres of the roughly 4,347 acres inside the outer 5 ft line, so the other half of the water is shallower than 40 feet. The sharpest drop is between 50 and 55 feet, where the mapped water sheds 551 acres.
- How accurate is this Lake Michigamme 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.
