How deep is Bass Lake?

Bass Lake reaches a maximum depth of 58 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 11 closed depth contours over about 62 acres, and half of that water sits inside the 30 ft line. The 58 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 55 ft.

Where is the deepest part of Bass Lake?

The deepest charted water on Bass Lake lies inside the 55 ft contour, toward the eastern side of the lake. That contour encloses 1.9 acres, 3% 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 Bass Lake is shallower than 30 feet?

About half. The 30 ft contour encloses 26 acres of the roughly 62 acres inside the outer 5 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 20 and 25 feet, where the mapped water sheds 9 acres.

How accurate is this Bass 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.

Bass Lake depth map

Bass Lake in Dickinson County, Michigan reaches a depth of 58 feet. Bass Lake is charted here across 11 closed depth contours, from the 5 ft line down to 55 ft, enclosing about 62 acres of water. Half of that water lies inside the 30 ft line, and only 1.9 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 62 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 58 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Bass Lake: an evenly graded bottom

Inside its outermost 5 ft contour the survey charts about 62 acres of Bass Lake, with the 30 ft line enclosing half of it, so the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. The sharpest change on the chart is between 20 and 25 ft, where the mapped water loses 9 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 55 ft contour holds 1.9 acres, 3% of the mapped water, toward the eastern side of the lake. Nothing here reaches a true cold-water layer at 58 ft, so structure does the thermocline's work: the points and inside turns where the 20 and 25 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Bass Lake

At 58 ft, Bass 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 55 ft hole, 1.9 acres of it, at first light, then move up onto the 20–25 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.
