Connecticut lake depth maps

Keeney Cove depth map

Keeney Cove in Glastonbury, Connecticut reaches a depth of 24 feet. Keeney Cove is charted here across 5 closed depth contours, from the 0 ft line down to 18 ft, enclosing about 73 acres of water. Half of that water lies inside the 3 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 73 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 Keeney Cove: a broad shallow flat

The survey encloses about 73 acres of Keeney Cove inside its 0 ft contour, and half of that water lies inside the 3 ft line, so most of this Glastonbury water is shallow and the depth is concentrated in one part of the basin. Between 0 and 3 ft the mapped water sheds 43 acres in 3 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. The 18 ft contour, toward the southeastern 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. Topping out at 24 ft, weed growth structures this water more than depth does, but the 0.1-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 Keeney Cove

A shallow lake like Keeney Cove 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 0.1 acres inside the 18 ft contour. Start there, then hunt the subtle single-contour depressions across the 73-acre basin. Check ice thickness locally before you walk out.

Keeney Cove depth map FAQs

How deep is Keeney Cove?
Keeney Cove reaches a maximum depth of 24 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 5 closed depth contours over about 73 acres, and half of that water sits inside the 3 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 18 ft.
Where is the deepest part of Keeney Cove?
The deepest charted water on Keeney Cove lies inside the 18 ft contour, toward the southeastern 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 Keeney Cove is shallower than 3 feet?
About half. The 3 ft contour encloses 30 acres of the roughly 73 acres inside the outer 0 ft line, so the other half of the water is shallower than 3 feet. The sharpest drop is between 0 and 3 feet, where the mapped water sheds 43 acres.
How accurate is this Keeney Cove 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.
