How deep is Pine Lake?

Pine Lake is at least 90 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 80 ft contour, and the water may run deeper still.

Where is the deepest part of Pine Lake?

The deepest charted water on Pine Lake lies inside the 80 ft contour, toward the middle of the lake. That contour encloses 3.7 acres, 1.6% 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 Pine Lake is shallower than 40 feet?

About half. The 40 ft contour encloses 68 acres of the roughly 225 acres inside the outer 10 ft line, so the other half of the water is shallower than 40 feet. The sharpest drop is between 20 and 30 feet, where the mapped water sheds 55 acres.

How accurate is this Pine 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.

Pine Lake depth map

Pine Lake in Oakland County, Michigan reaches a depth of more than 90 feet at its deepest surveyed sounding. Pine Lake is charted here across 8 closed depth contours, from the 10 ft line down to 80 ft, enclosing about 225 acres of water. Half of that water lies inside the 40 ft line, and only 3.7 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Depth contour	Water inside it	Share of mapped water
10 ft	225 acres	100%
20 ft	177 acres	79%
30 ft	122 acres	54%
40 ft	68 acres	30%

80 ft	3.7 acres	1.6%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 225 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 90 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Pine Lake: a stepped drop into deep water

About 225 acres of Pine Lake sit inside the survey's 10 ft contour, and half of that water is already gone by the 40 ft line: the drop to the deep basin comes in stages, each contour giving up another slice of water, rather than in one abrupt wall. The steepest break on the chart runs from 20 down to 30 ft: 55 acres of bottom fall away across 10 ft there, which makes that band the first contour to work. The deepest 80 ft contour holds 3.7 acres, 1.6% of the mapped water, toward the middle of the lake. 90 ft of water makes this a two-story fishery: warm-water fish hold the 10-to-40 ft ground while the basin can stay cold below the summer thermocline, and the traffic between the two runs along the 20–30 ft break at first and last light.

Ice fishing on Pine Lake

Pine 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 80 ft hole. The 20–30 ft band on the chart above is that edge: 55 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 10-to-40 ft flat. Check ice thickness locally before you walk out.
