North Lake depth map

North Lake in Lake County, Michigan reaches a depth of 28 feet. North Lake is charted here across 5 closed depth contours, from the 5 ft line down to 25 ft, enclosing about 54 acres of water. Half of that water lies inside the 10 ft line, and only 2.8 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 54 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 28 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing North Lake: a broad shallow flat

The survey encloses about 54 acres of North Lake inside its 5 ft contour, and half of that water lies inside the 10 ft line, so most of this Lake County water is shallow and the depth is concentrated in one part of the basin. Between 5 and 10 ft the mapped water sheds 28 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. 2.8 acres, 5.3% of the mapped water, lie inside the deepest 25 ft contour, toward the western side of the lake. Topping out at 28 ft, weed growth structures this water more than depth does, but the 2.8-acre deep spot still concentrates fish in the heat of summer, and the one-contour depressions on the chart are the ones most anglers row straight over.

Ice fishing on North Lake

A shallow lake like North Lake is usually among the first to make safe ice, and once the weed beds die back the fish have very little deep water to spread into: just 2.8 acres inside the 25 ft contour. Start there, then hunt the subtle single-contour depressions across the 54-acre basin. Check ice thickness locally before you walk out.

North Lake depth map FAQs

How deep is North Lake?
North Lake reaches a maximum depth of 28 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 5 closed depth contours over about 54 acres, and half of that water sits inside the 10 ft line. The 28 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 25 ft.
Where is the deepest part of North Lake?
The deepest charted water on North Lake lies inside the 25 ft contour, toward the western side of the lake. That contour encloses 2.8 acres, 5.3% of the mapped water, so it is a small target on a small water, the depth chart above gives the contour to line up on.
How much of North Lake is shallower than 10 feet?
About half. The 10 ft contour encloses 26 acres of the roughly 54 acres inside the outer 5 ft line, so the other half of the water is shallower than 10 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 28 acres.
How accurate is this North 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.
