Michigan lake depth maps
Hamlin Lake depth map
Hamlin Lake in Mason County, Michigan reaches a depth of more than 65 feet at its deepest surveyed contour. Hamlin Lake is charted here across 5 closed depth contours, from the 5 ft line down to 65 ft, enclosing about 4,955 acres of water. Half of that water lies inside the 16 ft line, and only 57 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 | 4,955 acres | 100% |
| 16 ft | 1,787 acres | 36% |
| 33 ft | 794 acres | 16% |
| 49 ft | 157 acres | 3.2% |
| 65 ft | 57 acres | 1.2% |
Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 4,955 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 Hamlin Lake: a wide shallow flat over a deep hole
Inside its outermost 5 ft contour the survey charts about 4,955 acres of Hamlin Lake, with the 16 ft line enclosing half of it, so most of this Mason 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 16 ft, where the mapped water loses 3,168 acres in 11 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 57 acres, 1.2% of the mapped water, lie inside the deepest 65 ft contour, toward the northwestern corner of the lake. At 65 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-16 ft ground, and the fish that move between the two do it along the 5–16 ft break at first and last light.
Ice fishing on Hamlin Lake
Deep water like Hamlin 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 65 ft hole. That edge is the 5–16 ft band on the chart above, where 3,168 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-16 ft flat. Check ice thickness locally before you walk out.
Hamlin Lake depth map FAQs
- How deep is Hamlin Lake?
- Hamlin Lake is more than 65 feet deep. The deepest contour in the Michigan DNR Inland Lake Contours survey is the 65 foot line, and the lake continues deeper inside it.
- Where is the deepest part of Hamlin Lake?
- The deepest charted water on Hamlin Lake lies inside the 65 ft contour, toward the northwestern corner of the lake. That contour encloses 57 acres, 1.2% 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 Hamlin Lake is shallower than 16 feet?
- About half. The 16 ft contour encloses 1,787 acres of the roughly 4,955 acres inside the outer 5 ft line, so the other half of the water is shallower than 16 feet. The sharpest drop is between 5 and 16 feet, where the mapped water sheds 3,168 acres.
- How accurate is this Hamlin 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.
