How deep is Little Long Lake?

Little Long Lake is more than 60 feet deep. The deepest contour in the Michigan DNR Inland Lake Contours survey is the 60 foot line, and the lake continues deeper inside it.

Where is the deepest part of Little Long Lake?

The deepest charted water on Little Long Lake lies inside the 60 ft contour, toward the southeastern corner of the lake. That contour encloses under an acre, under 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 Little Long Lake is shallower than 30 feet?

About half. The 30 ft contour encloses 21 acres of the roughly 55 acres inside the outer 5 ft line, so the other half of the water is shallower than 30 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 15 acres.

How accurate is this Little Long 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.

Little Long Lake depth map

Little Long Lake in Clare County, Michigan reaches a depth of more than 60 feet at its deepest surveyed contour. Little Long Lake is charted here across 7 closed depth contours, from the 5 ft line down to 60 ft, enclosing about 55 acres of water. Half of that water lies inside the 30 ft line, and only under an acre lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Little Long Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
5 ft	55 acres	100%
10 ft	40 acres	74%
20 ft	31 acres	58%
30 ft	21 acres	38%
40 ft	11 acres	21%
50 ft	2.4 acres	4.4%
60 ft	under 1 acre	under 1%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 55 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.

Fishing Little Long Lake: a stepped drop into deep water

Inside its outermost 5 ft contour the survey charts about 55 acres of Little Long Lake, with the 30 ft line enclosing half of it, so the bottom steps down contour by contour into the deep basin rather than shelving flat or plunging all at once. The sharpest change on the chart is between 5 and 10 ft, where the mapped water loses 15 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The 60 ft contour, toward the southeastern corner of the lake, encloses under an acre of water, a single pocket rather than a basin, but one worth a drift over in high summer. At 60 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 5-to-30 ft ground, and the fish that move between the two do it along the 5–10 ft break at first and last light.

Ice fishing on Little Long Lake

Deep water like Little Long Lake freezes later and less evenly than the shallow lakes around it, and the winter bite sets up on the first real break, not out over the 60 ft hole. That edge is the 5–10 ft band on the chart above, where 15 acres of bottom tilt away, and panfish and walleye work up and down it through the day. By late ice the fish push back onto the 5-to-30 ft flat. Check ice thickness locally before you walk out.
