How deep is Amos Lake?

Amos Lake reaches a maximum depth of 42 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 8 closed depth contours over about 113 acres, and half of that water sits inside the 18 ft line.

Where is the deepest part of Amos Lake?

The deepest charted water on Amos Lake lies inside the 42 ft contour, toward the middle of the lake. That contour encloses 5.4 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 Amos Lake is shallower than 18 feet?

About half. The 18 ft contour encloses 51 acres of the roughly 113 acres inside the outer 0 ft line, so the other half of the water is shallower than 18 feet. The sharpest drop is between 0 and 6 feet, where the mapped water sheds 40 acres.

How accurate is this Amos 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.

Amos Lake depth map

Amos Lake in Preston, Connecticut reaches a depth of 42 feet. Amos Lake is charted here across 8 closed depth contours, from the 0 ft line down to 42 ft, enclosing about 113 acres of water. Half of that water lies inside the 18 ft line, and only 5.4 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Amos Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	113 acres	100%
6 ft	73 acres	65%
12 ft	61 acres	55%
18 ft	51 acres	46%
24 ft	41 acres	37%
30 ft	28 acres	25%
36 ft	19 acres	17%
42 ft	5.4 acres	4.8%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 113 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 Amos Lake: an evenly graded bottom

Inside its outermost 0 ft contour the survey charts about 113 acres of Amos Lake, with the 18 ft line enclosing half of it, so the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. The sharpest change on the chart is between 0 and 6 ft, where the mapped water loses 40 acres in 6 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 42 ft contour holds 5.4 acres, 4.8% of the mapped water, toward the middle of the lake. Nothing here reaches a true cold-water layer at 42 ft, so structure does the thermocline's work: the points and inside turns where the 0 and 6 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Amos Lake

At 42 ft, Amos Lake is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 42 ft hole, 5.4 acres of it, at first light, then move up onto the 0–6 ft break as the sun gets up, and fish the flats inside the 18 ft line through the middle of the day. Check ice thickness locally before you walk out.
