How deep is Lake Charlevoix?

Lake Charlevoix reaches a maximum depth of 122 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 10 closed depth contours over about 16,904 acres, and half of that water sits inside the 70 ft line. The 122 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 110 ft.

Where is the deepest part of Lake Charlevoix?

The deepest charted water on Lake Charlevoix lies inside the 110 ft contour, toward the northeastern corner of the lake. That contour encloses 1,593 acres, 9.4% 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 Charlevoix is shallower than 70 feet?

About half. The 70 ft contour encloses 8,091 acres of the roughly 16,904 acres inside the outer 10 ft line, so the other half of the water is shallower than 70 feet. The sharpest drop is between 100 and 110 feet, where the mapped water sheds 1,907 acres.

How accurate is this Lake Charlevoix 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.

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 16,904 acres inside the outermost charted contour (the 10 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 122 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Lake Charlevoix: steep walls and a big basin

Inside its outermost 10 ft contour the survey charts about 16,904 acres of Lake Charlevoix, with the 70 ft line enclosing half of it, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. The sharpest change on the chart is between 100 and 110 ft, where the mapped water loses 1,907 acres in 10 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 1,593 acres, 9.4% of the mapped water, lie inside the deepest 110 ft contour, toward the northeastern corner of the lake. At 122 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 10-to-70 ft ground, and the fish that move between the two do it along the 100–110 ft break at first and last light.

Ice fishing on Lake Charlevoix

Deep water like Lake Charlevoix 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 110 ft hole. That edge is the 100–110 ft band on the chart above, where 1,907 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 10-to-70 ft flat. Check ice thickness locally before you walk out.
