How deep is Baldwins Lake?

Baldwins Lake is at least 55 feet deep. That figure is the deepest surveyed sounding in the Michigan DNR Inland Lake Contours survey, a point measurement rather than a closed contour, so the deepest line you can actually trace on the map is the 50 ft contour, and the water may run deeper still.

Where is the deepest part of Baldwins Lake?

The deepest charted water on Baldwins Lake lies inside the 50 ft contour, toward the middle of the lake. That contour encloses 23 acres, 13% 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 Baldwins Lake is shallower than 30 feet?

About half. The 30 ft contour encloses 78 acres of the roughly 175 acres inside the outer 10 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 10 and 20 feet, where the mapped water sheds 49 acres.

How accurate is this Baldwins 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.

Baldwins Lake depth map

Baldwins Lake in Cass County, Michigan reaches a depth of more than 55 feet at its deepest surveyed sounding. Baldwins Lake is charted here across 5 closed depth contours, from the 10 ft line down to 50 ft, enclosing about 175 acres of water. Half of that water lies inside the 30 ft line, and only 23 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Baldwins Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
10 ft	175 acres	100%
20 ft	126 acres	72%
30 ft	78 acres	45%
40 ft	50 acres	29%
50 ft	23 acres	13%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 175 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 55 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Baldwins Lake: an evenly graded bottom

About 175 acres of Baldwins Lake sit inside the survey's 10 ft contour, and half of that water is already gone by the 30 ft line: the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. The steepest break on the chart runs from 10 down to 20 ft: 49 acres of bottom fall away across 10 ft there, which makes that band the first contour to work. The deepest 50 ft contour holds 23 acres, 13% of the mapped water, toward the middle of the lake. Nothing here reaches a true cold-water layer at 55 ft, so structure does the thermocline's work: the points and inside turns where the 10 and 20 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Baldwins Lake

At 55 ft, Baldwins Lake is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 50 ft hole, 23 acres of it, at first light, then move up onto the 10–20 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.
