How deep is Gull Lake?

Gull Lake reaches a maximum depth of 110 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 12 closed depth contours over about 2,043 acres, and half of that water sits inside the 50 ft line.

Where is the deepest part of Gull Lake?

The deepest charted water on Gull Lake lies inside the 110 ft contour, toward the middle of the lake. That contour encloses 29 acres, 1.4% 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 Gull Lake is shallower than 50 feet?

About half. The 50 ft contour encloses 1,015 acres of the roughly 2,043 acres inside the outer 5 ft line, so the other half of the water is shallower than 50 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 225 acres.

How accurate is this Gull 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.

Gull Lake depth map

Gull Lake in Kalamazoo County, Michigan reaches a depth of 110 feet. Gull Lake is charted here across 12 closed depth contours, from the 5 ft line down to 110 ft, enclosing about 2,043 acres of water. Half of that water lies inside the 50 ft line, and only 29 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 2,043 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 Gull Lake: a stepped drop into deep water

The survey encloses about 2,043 acres of Gull Lake inside its 5 ft contour, and half of that water lies inside the 50 ft line, so the drop to the deep basin comes in stages, each contour giving up another slice of water, rather than in one abrupt wall. Between 5 and 10 ft the mapped water sheds 225 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 110 ft contour holds 29 acres, 1.4% of the mapped water, toward the middle of the lake. 110 ft of water makes this a two-story fishery: warm-water fish hold the 5-to-50 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 Gull Lake

Gull 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 110 ft hole. The 5–10 ft band on the chart above is that edge: 225 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-50 ft flat. Check ice thickness locally before you walk out.
