Chamberlain Lake depth map
Chamberlain Lake in Bethany, Connecticut reaches a depth of 65 feet. Chamberlain Lake is charted here across 13 closed depth contours, from the 0 ft line down to 60 ft, enclosing about 107 acres of water. Half of that water lies inside the 25 ft line, and only 3.7 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 CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 107 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. The survey also records a 65 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.
Fishing Chamberlain Lake: a stepped drop into deep water
Inside its outermost 0 ft contour the survey charts about 107 acres of Chamberlain Lake, with the 25 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 5 and 10 ft, where the mapped water loses 16 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 60 ft contour holds 3.7 acres, 3.4% of the mapped water, toward the southern end of the lake. 65 ft of water makes this a two-story fishery: warm-water fish hold the 0-to-25 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 Chamberlain Lake
Chamberlain 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 60 ft hole. The 5–10 ft band on the chart above is that edge: 16 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-25 ft flat. Check ice thickness locally before you walk out.
Chamberlain Lake depth map FAQs
- How deep is Chamberlain Lake?
- Chamberlain Lake reaches a maximum depth of 65 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 13 closed depth contours over about 107 acres, and half of that water sits inside the 25 ft line. The 65 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 60 ft.
- Where is the deepest part of Chamberlain Lake?
- The deepest charted water on Chamberlain Lake lies inside the 60 ft contour, toward the southern end of the lake. That contour encloses 3.7 acres, 3.4% 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 Chamberlain Lake is shallower than 25 feet?
- About half. The 25 ft contour encloses 47 acres of the roughly 107 acres inside the outer 0 ft line, so the other half of the water is shallower than 25 feet. The sharpest drop is between 5 and 10 feet, where the mapped water sheds 16 acres.
- How accurate is this Chamberlain 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.
