How deep is Lake Gogebic?

Lake Gogebic reaches a maximum depth of 35 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 7 closed depth contours over about 13,035 acres, and half of that water sits inside the 30 ft line.

Where is the deepest part of Lake Gogebic?

The deepest charted water on Lake Gogebic lies inside the 35 ft contour, toward the northern end of the lake. That contour encloses 312 acres, 2.4% 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 Gogebic is shallower than 30 feet?

About half. The 30 ft contour encloses 4,276 acres of the roughly 13,035 acres inside the outer 5 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 30 and 35 feet, where the mapped water sheds 3,964 acres.

How accurate is this Lake Gogebic 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.

Lake Gogebic depth map

Lake Gogebic in Ontonagon County, Michigan reaches a depth of 35 feet. Lake Gogebic is charted here across 7 closed depth contours, from the 5 ft line down to 35 ft, enclosing about 13,035 acres of water. Half of that water lies inside the 30 ft line, and only 312 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Lake Gogebic depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
5 ft	13,035 acres	100%
10 ft	11,874 acres	91%
15 ft	10,454 acres	80%
20 ft	9,321 acres	72%
25 ft	7,965 acres	61%
30 ft	4,276 acres	33%
35 ft	312 acres	2.4%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 13,035 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 Gogebic: steep sides for its size

The survey encloses about 13,035 acres of Lake Gogebic inside its 5 ft contour, and half of that water lies inside the 30 ft line, so depth comes quickly here, with no long shallow margin before the bottom drops away. Between 30 and 35 ft the mapped water sheds 3,964 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 35 ft contour holds 312 acres, 2.4% of the mapped water, toward the northern end of the lake. Nothing here reaches a true cold-water layer at 35 ft, so structure does the thermocline's work: the points and inside turns where the 30 and 35 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Lake Gogebic

At 35 ft, Lake Gogebic is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 35 ft hole, 312 acres of it, at first light, then move up onto the 30–35 ft break as the sun gets up, and fish the flats inside the 30 ft line through the middle of the day. Check ice thickness locally before you walk out.
