How deep is George Lake?

George Lake reaches a maximum depth of 82 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 522 acres, and half of that water sits inside the 20 ft line. The 82 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 80 ft.

Where is the deepest part of George Lake?

The deepest charted water on George Lake lies inside the 80 ft contour, toward the southeastern corner of the lake. That contour encloses 12 acres, 2.2% 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 George Lake is shallower than 20 feet?

About half. The 20 ft contour encloses 224 acres of the roughly 522 acres inside the outer 5 ft line, so the other half of the water is shallower than 20 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 138 acres.

How accurate is this George 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.

George Lake depth map

George Lake in Branch County, Michigan reaches a depth of 82 feet. George Lake is charted here across 9 closed depth contours, from the 5 ft line down to 80 ft, enclosing about 522 acres of water. Half of that water lies inside the 20 ft line, and only 12 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

George Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
5 ft	522 acres	100%
10 ft	384 acres	74%
20 ft	224 acres	43%
30 ft	167 acres	32%
40 ft	141 acres	27%

70 ft	39 acres	7.6%
80 ft	12 acres	2.2%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 522 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 82 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing George Lake: a wide shallow flat over a deep hole

Inside its outermost 5 ft contour the survey charts about 522 acres of George Lake, with the 20 ft line enclosing half of it, so most of this Branch County water is shallow and the depth is concentrated in one part of the basin. The sharpest change on the chart is between 5 and 10 ft, where the mapped water loses 138 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 12 acres, 2.2% of the mapped water, lie inside the deepest 80 ft contour, toward the southeastern corner of the lake. At 82 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-20 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 George Lake

Deep water like George 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 80 ft hole. That edge is the 5–10 ft band on the chart above, where 138 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-20 ft flat. Check ice thickness locally before you walk out.
