How deep is Highland Lake?

Highland Lake reaches a maximum depth of 60 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 11 closed depth contours over about 446 acres, and half of that water sits inside the 24 ft line.

Where is the deepest part of Highland Lake?

The deepest charted water on Highland Lake lies inside the 60 ft contour, toward the northwestern corner of the lake. That contour encloses under an acre, 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 Highland Lake is shallower than 24 feet?

About half. The 24 ft contour encloses 191 acres of the roughly 446 acres inside the outer 0 ft line, so the other half of the water is shallower than 24 feet. The sharpest drop is between 6 and 12 feet, where the mapped water sheds 79 acres.

How accurate is this Highland 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.

Highland Lake depth map

Highland Lake in Winchester, Connecticut reaches a depth of 60 feet. Highland Lake is charted here across 11 closed depth contours, from the 0 ft line down to 60 ft, enclosing about 446 acres of water. Half of that water lies inside the 24 ft line, and only under an acre 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 446 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 Highland Lake: a stepped drop into deep water

The survey encloses about 446 acres of Highland Lake inside its 0 ft contour, and half of that water lies inside the 24 ft line, so the bottom steps down contour by contour into the deep basin rather than shelving flat or plunging all at once. Between 6 and 12 ft the mapped water sheds 79 acres in 6 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. The 60 ft contour, toward the northwestern corner of the lake, encloses under an acre of water, a single pocket rather than a basin, but one worth a drift over in high summer. At 60 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 0-to-24 ft ground, and the fish that move between the two do it along the 6–12 ft break at first and last light.

Ice fishing on Highland Lake

Deep water like Highland Lake freezes later and less evenly than the shallow lakes around it, and the winter bite sets up on the first real break, not out over the 60 ft hole. That edge is the 6–12 ft band on the chart above, where 79 acres of bottom tilt away, and panfish and walleye work up and down it through the day. By late ice the fish push back onto the 0-to-24 ft flat. Check ice thickness locally before you walk out.
