How deep is Fremont Lake?

Fremont Lake is at least 88 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 75 ft contour, and the water may run deeper still.

Where is the deepest part of Fremont Lake?

The deepest charted water on Fremont Lake lies inside the 75 ft contour, toward the northern end of the lake. That contour encloses 58 acres, 11% of the mapped water, so it is a small target on a big lake, the depth chart above gives the contour to line up on.

How much of Fremont Lake is shallower than 50 feet?

About half. The 50 ft contour encloses 254 acres of the roughly 535 acres inside the outer 15 ft line, so the other half of the water is shallower than 50 feet. The sharpest drop is between 15 and 25 feet, where the mapped water sheds 85 acres.

How accurate is this Fremont 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.

Fremont Lake depth map

Fremont Lake in Newaygo County, Michigan reaches a depth of more than 88 feet at its deepest surveyed sounding. Fremont Lake is charted here across 5 closed depth contours, from the 15 ft line down to 75 ft, enclosing about 535 acres of water. Half of that water lies inside the 50 ft line, and only 58 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Fremont Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
15 ft	535 acres	100%
25 ft	450 acres	84%
35 ft	372 acres	70%
50 ft	254 acres	47%
75 ft	58 acres	11%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 535 acres inside the outermost charted contour (the 15 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 88 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Fremont Lake: steep walls and a big basin

The survey encloses about 535 acres of Fremont Lake inside its 15 ft contour, and half of that water lies inside the 50 ft line, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. Between 15 and 25 ft the mapped water sheds 85 acres in 10 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. 58 acres, 11% of the mapped water, lie inside the deepest 75 ft contour, toward the northern end of the lake. At 88 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 15-to-50 ft ground, and the fish that move between the two do it along the 15–25 ft break at first and last light.

Ice fishing on Fremont Lake

Deep water like Fremont 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 75 ft hole. That edge is the 15–25 ft band on the chart above, where 85 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 15-to-50 ft flat. Check ice thickness locally before you walk out.
