How deep is Tea Lake?

Tea Lake reaches a maximum depth of 70 feet in the Michigan DNR Inland Lake Contours survey. Most of it is far shallower: the survey charts 14 closed depth contours over about 212 acres, and half of that water sits inside the 15 ft line.

Where is the deepest part of Tea Lake?

The deepest charted water on Tea Lake lies inside the 70 ft contour, toward the northern end of the lake. That contour encloses 2.2 acres, 1.1% 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 Tea Lake is shallower than 15 feet?

About half. The 15 ft contour encloses 93 acres of the roughly 212 acres inside the outer 5 ft line, so the other half of the water is shallower than 15 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 66 acres.

How accurate is this Tea 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.

Tea Lake depth map

Tea Lake in Oscoda County, Michigan reaches a depth of 70 feet. Tea Lake is charted here across 14 closed depth contours, from the 5 ft line down to 70 ft, enclosing about 212 acres of water. Half of that water lies inside the 15 ft line, and only 2.2 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Acreages are computed from the closed Michigan DNR Inland Lake Contours contour rings, with islands subtracted. Shares are of the 212 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 Tea Lake: a wide shallow flat over a deep hole

The survey encloses about 212 acres of Tea Lake inside its 5 ft contour, and half of that water lies inside the 15 ft line, so the bulk of this Oscoda County water sits on a shallow flat, with the real depth packed into one part of the basin. Between 5 and 10 ft the mapped water sheds 66 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 70 ft contour holds 2.2 acres, 1.1% of the mapped water, toward the northern end of the lake. 70 ft of water makes this a two-story fishery: warm-water fish hold the 5-to-15 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 Tea Lake

Tea 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 70 ft hole. The 5–10 ft band on the chart above is that edge: 66 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-15 ft flat. Check ice thickness locally before you walk out.
