Michigan lake depth maps
Lake George depth map
Lake George in Ogemaw County, Michigan reaches a depth of 48 feet. Lake George is charted here across 6 closed depth contours, from the 5 ft line down to 45 ft, enclosing about 90 acres of water. Half of that water lies inside the 45 ft line, and only 10 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

| Depth contour | Water inside it | Share of mapped water |
|---|---|---|
| 5 ft | 90 acres | 100% |
| 10 ft | 80 acres | 89% |
| 20 ft | 76 acres | 84% |
| 30 ft | 69 acres | 77% |
| 40 ft | 49 acres | 54% |
| 45 ft | 10 acres | 11% |
Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 90 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 48 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.
Fishing Lake George: steep sides for its size
The survey encloses about 90 acres of Lake George inside its 5 ft contour, and half of that water lies inside the 45 ft line, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. Between 40 and 45 ft the mapped water sheds 39 acres in 5 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. 10 acres, 11% of the mapped water, lie inside the deepest 45 ft contour, toward the southeastern corner of the lake. With 48 ft at its deepest there is no true cold-water layer here, so structure does the work the thermocline does elsewhere: fish the points and inside turns where the 40 and 45 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.
Ice fishing on Lake George
Lake George's 48 ft is a workable ice depth, enough water to hold fish all winter, without the slow freeze-up of a big basin. First light belongs on the 45 ft hole, all 10 acres of it; as the sun gets up, move onto the 40–45 ft break, and spend the middle of the day on the flats inside the 45 ft line. Check ice thickness locally before you walk out.
Lake George depth map FAQs
- How deep is Lake George?
- Lake George reaches a maximum depth of 48 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 90 acres, and half of that water sits inside the 45 ft line. The 48 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 45 ft.
- Where is the deepest part of Lake George?
- The deepest charted water on Lake George lies inside the 45 ft contour, toward the southeastern corner of the lake. That contour encloses 10 acres, 11% 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 Lake George is shallower than 45 feet?
- About half. The 45 ft contour encloses 10 acres of the roughly 90 acres inside the outer 5 ft line, so the other half of the water is shallower than 45 feet. The sharpest drop is between 40 and 45 feet, where the mapped water sheds 39 acres.
- How accurate is this Lake George 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.
