How deep is Emily Lake?

Emily Lake reaches a maximum depth of 90 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 56 acres, and half of that water sits inside the 40 ft line. The 90 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 Emily Lake?

The deepest charted water on Emily Lake lies inside the 80 ft contour, toward the southern end of the lake. That contour encloses 2.7 acres, 4.8% 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 Emily Lake is shallower than 40 feet?

About half. The 40 ft contour encloses 22 acres of the roughly 56 acres inside the outer 5 ft line, so the other half of the water is shallower than 40 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 6 acres.

How accurate is this Emily 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.

Emily Lake depth map

Emily Lake in Houghton County, Michigan reaches a depth of 90 feet. Emily Lake is charted here across 9 closed depth contours, from the 5 ft line down to 80 ft, enclosing about 56 acres of water. Half of that water lies inside the 40 ft line, and only 2.7 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Emily Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
5 ft	56 acres	100%
10 ft	50 acres	88%
20 ft	42 acres	75%
30 ft	30 acres	52%
40 ft	22 acres	38%
50 ft	16 acres	28%
60 ft	9.8 acres	17%
70 ft	6 acres	11%
80 ft	2.7 acres	4.8%

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 56 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 90 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Emily Lake: a stepped drop into deep water

The survey encloses about 56 acres of Emily Lake inside its 5 ft contour, and half of that water lies inside the 40 ft line, so the drop to the deep basin comes in stages, each contour giving up another slice of water, rather than in one abrupt wall. Between 5 and 10 ft the mapped water sheds 6 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. The deepest 80 ft contour holds 2.7 acres, 4.8% of the mapped water, toward the southern end of the lake. 90 ft of water makes this a two-story fishery: warm-water fish hold the 5-to-40 ft ground while the basin can stay cold below the summer thermocline, and the traffic between the two runs along the 5–10 ft break at first and last light.

Ice fishing on Emily Lake

Emily Lake freezes later and less evenly than the shallow waters around it, and the winter bite sets up on the first real break rather than out over the 80 ft hole. The 5–10 ft band on the chart above is that edge: 6 acres of bottom tilt away there, and panfish and walleye slide up and down it through the day. Late ice pushes fish back onto the 5-to-40 ft flat. Check ice thickness locally before you walk out.
