How deep is Beaver Lake?

Beaver Lake is more than 39 feet deep. The deepest contour in the Michigan DNR Inland Lake Contours survey is the 39 foot line, and the lake continues deeper inside it.

Where is the deepest part of Beaver Lake?

The deepest charted water on Beaver Lake lies inside the 30 ft contour, toward the western side of the lake. That contour encloses 293 acres, 45% of the mapped water, so it is a broad slice of the bottom rather than a pinpoint target, the depth chart above gives the contour to line up on.

How much of Beaver Lake is shallower than 30 feet?

About half. The 30 ft contour encloses 293 acres of the roughly 653 acres inside the outer 10 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 25 and 30 feet, where the mapped water sheds 182 acres.

How accurate is this Beaver 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.

Beaver Lake depth map

Beaver Lake in Alger County, Michigan reaches a depth of more than 39 feet at its deepest surveyed contour. Beaver Lake is charted here across 5 closed depth contours, from the 10 ft line down to 30 ft, enclosing about 653 acres of water. Half of that water lies inside the 30 ft line, and only 293 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Beaver Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
10 ft	653 acres	100%
15 ft	609 acres	93%
20 ft	558 acres	86%
25 ft	475 acres	73%
30 ft	293 acres	45%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 653 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 38 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Beaver Lake: steep sides for its size

Inside its outermost 10 ft contour the survey charts about 653 acres of Beaver Lake, with the 30 ft line enclosing half of it, so depth comes quickly here, with no long shallow margin before the bottom drops away. The sharpest change on the chart is between 25 and 30 ft, where the mapped water loses 182 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 30 ft contour holds 293 acres, 45% of the mapped water, toward the western side of the lake. Nothing here reaches a true cold-water layer at 39 ft, so structure does the thermocline's work: the points and inside turns where the 25 and 30 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Beaver Lake

At 39 ft, Beaver 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 30 ft hole, 293 acres of it, at first light, then move up onto the 25–30 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.
