How deep is East Twin Lake?

East Twin Lake reaches a maximum depth of 80 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 569 acres, and half of that water sits inside the 40 ft line.

Where is the deepest part of East Twin Lake?

The deepest charted water on East Twin Lake lies inside the 80 ft contour, toward the southern end of the lake. That contour encloses 2 acres, under 1% 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 East Twin Lake is shallower than 40 feet?

About half. The 40 ft contour encloses 278 acres of the roughly 569 acres inside the outer 0 ft line, so the other half of the water is shallower than 40 feet. The sharpest drop is between 0 and 10 feet, where the mapped water sheds 120 acres.

How accurate is this East Twin Lake depth map?

The contours come from the CT DEEP Lake Bathymetry 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.

East Twin Lake depth map

East Twin Lake in Salisbury, Connecticut reaches a depth of 80 feet. East Twin Lake is charted here across 9 closed depth contours, from the 0 ft line down to 80 ft, enclosing about 569 acres of water. Half of that water lies inside the 40 ft line, and only 2 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

East Twin Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	569 acres	100%
10 ft	449 acres	79%
20 ft	391 acres	69%
30 ft	339 acres	60%
40 ft	278 acres	49%
50 ft	198 acres	35%
60 ft	126 acres	22%
70 ft	44 acres	7.7%
80 ft	2 acres	under 1%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 569 acres inside the outermost charted contour (the 0 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 East Twin Lake: a stepped drop into deep water

Inside its outermost 0 ft contour the survey charts about 569 acres of East Twin Lake, with the 40 ft line enclosing half of it, so the drop to the deep basin comes in stages, each contour giving up another slice of water, rather than in one abrupt wall. The sharpest change on the chart is between 0 and 10 ft, where the mapped water loses 120 acres in 10 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 80 ft contour holds 2 acres, under 1% of the mapped water, toward the southern end of the lake. 80 ft of water makes this a two-story fishery: warm-water fish hold the 0-to-40 ft ground while the basin can stay cold below the summer thermocline, and the traffic between the two runs along the 0–10 ft break at first and last light.

Ice fishing on East Twin Lake

East Twin 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 0–10 ft band on the chart above is that edge: 120 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 0-to-40 ft flat. Check ice thickness locally before you walk out.
