Lake Housatonic depth map

Lake Housatonic in Oxford, Seymour, Derby, Monroe, Shelton, Connecticut reaches a depth of 24 feet. Lake Housatonic is charted here across 8 closed depth contours, from the 0 ft line down to 21 ft, enclosing about 338 acres of water. Half of that water lies inside the 9 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 CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 338 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 24 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Lake Housatonic: an evenly graded bottom

About 338 acres of Lake Housatonic sit inside the survey's 0 ft contour, and half of that water is already gone by the 9 ft line: the bottom falls away at a steady rate rather than shelving off or dropping in one step. The steepest break on the chart runs from 9 down to 12 ft: 76 acres of bottom fall away across 3 ft there, which makes that band the first contour to work. 2.2 acres, under 1% of the mapped water, lie inside the deepest 21 ft contour, toward the middle of the lake. Topping out at 24 ft, weed growth structures this water more than depth does, but the 2.2-acre deep spot still concentrates fish in the heat of summer, and the one-contour depressions on the chart are the ones most anglers row straight over.

Ice fishing on Lake Housatonic

A shallow lake like Lake Housatonic is usually among the first to make safe ice, and once the weed beds die back the fish have very little deep water to spread into: just 2.2 acres inside the 21 ft contour. Start there, then hunt the subtle single-contour depressions across the 338-acre basin. Check ice thickness locally before you walk out.

Lake Housatonic depth map FAQs

How deep is Lake Housatonic?
Lake Housatonic reaches a maximum depth of 24 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 8 closed depth contours over about 338 acres, and half of that water sits inside the 9 ft line. The 24 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 21 ft.
Where is the deepest part of Lake Housatonic?
The deepest charted water on Lake Housatonic lies inside the 21 ft contour, toward the middle of the lake. That contour encloses 2.2 acres, under 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 Lake Housatonic is shallower than 9 feet?
About half. The 9 ft contour encloses 166 acres of the roughly 338 acres inside the outer 0 ft line, so the other half of the water is shallower than 9 feet. The sharpest drop is between 9 and 12 feet, where the mapped water sheds 76 acres.
How accurate is this Lake Housatonic 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.
