How deep is Cedar Lake?

Cedar Lake reaches a maximum depth of 40 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 68 acres, and half of that water sits inside the 20 ft line.

Where is the deepest part of Cedar Lake?

The deepest charted water on Cedar Lake lies inside the 40 ft contour, toward the southeastern corner of the lake. That contour encloses 1.2 acres, 1.8% 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 Cedar Lake is shallower than 20 feet?

About half. The 20 ft contour encloses 28 acres of the roughly 68 acres inside the outer 0 ft line, so the other half of the water is shallower than 20 feet. The sharpest drop is between 0 and 5 feet, where the mapped water sheds 14 acres.

How accurate is this Cedar 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.

Cedar Lake depth map

Cedar Lake in Chester, Connecticut reaches a depth of 40 feet. Cedar Lake is charted here across 9 closed depth contours, from the 0 ft line down to 40 ft, enclosing about 68 acres of water. Half of that water lies inside the 20 ft line, and only 1.2 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Cedar Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	68 acres	100%
5 ft	54 acres	79%
10 ft	46 acres	67%
15 ft	35 acres	52%
20 ft	28 acres	41%
25 ft	22 acres	32%
30 ft	16 acres	23%
35 ft	4 acres	5.9%
40 ft	1.2 acres	1.8%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 68 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 Cedar Lake: an evenly graded bottom

The survey encloses about 68 acres of Cedar Lake inside its 0 ft contour, and half of that water lies inside the 20 ft line, so the bottom falls away at a steady rate rather than shelving off or dropping in one step. Between 0 and 5 ft the mapped water sheds 14 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. 1.2 acres, 1.8% of the mapped water, lie inside the deepest 40 ft contour, toward the southeastern corner of the lake. With 40 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 0 and 5 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Ice fishing on Cedar Lake

Cedar Lake's 40 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 40 ft hole, all 1.2 acres of it; as the sun gets up, move onto the 0–5 ft break, and spend the middle of the day on the flats inside the 20 ft line. Check ice thickness locally before you walk out.
