How deep is Sage Lakes?

Sage Lakes is at least 36 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 30 ft contour, and the water may run deeper still.

Where is the deepest part of Sage Lakes?

The deepest charted water on Sage Lakes lies inside the 30 ft contour, toward the western side of the lake. That contour encloses 3.1 acres, 8.1% 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 Sage Lakes is shallower than 10 feet?

About half. The 10 ft contour encloses 14 acres of the roughly 38 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 24 acres.

How accurate is this Sage Lakes 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.

Sage Lakes depth map

Sage Lakes in Montmorency County, Michigan reaches a depth of more than 36 feet at its deepest surveyed sounding. Sage Lakes is charted here across 5 closed depth contours, from the 5 ft line down to 30 ft, enclosing about 38 acres of water. Half of that water lies inside the 10 ft line, and only 3.1 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Sage Lakes depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
5 ft	38 acres	100%
10 ft	14 acres	37%
15 ft	12 acres	31%
20 ft	7.8 acres	20%
30 ft	3.1 acres	8.1%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 38 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 36 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Sage Lakes: a broad shallow flat

About 38 acres of Sage Lakes sit inside the survey's 5 ft contour, and half of that water is already gone by the 10 ft line: most of this Montmorency County water is shallow and the depth is concentrated in one part of the basin. The steepest break on the chart runs from 5 down to 10 ft: 24 acres of bottom fall away across 5 ft there, which makes that band the first contour to work. 3.1 acres, 8.1% of the mapped water, lie inside the deepest 30 ft contour, toward the western side of the lake. With 36 ft at its deepest there is no true cold-water layer here, so structure does the work the thermocline does elsewhere: fish the points and inside turns where the 5 and 10 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Ice fishing on Sage Lakes

Sage Lakes's 36 ft is a workable ice depth, enough water to hold fish all winter, without the slow freeze-up of a big basin. First light belongs on the 30 ft hole, all 3.1 acres of it; as the sun gets up, move onto the 5–10 ft break, and spend the middle of the day on the flats inside the 10 ft line. Check ice thickness locally before you walk out.
