How deep is Coventry Lake?

Coventry Lake reaches a maximum depth of 36 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 7 closed depth contours over about 373 acres, and half of that water sits inside the 24 ft line.

Where is the deepest part of Coventry Lake?

The deepest charted water on Coventry Lake lies inside the 36 ft contour, toward the southern end of the lake. That contour encloses 6 acres, 1.6% 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 Coventry Lake is shallower than 24 feet?

About half. The 24 ft contour encloses 154 acres of the roughly 373 acres inside the outer 0 ft line, so the other half of the water is shallower than 24 feet. The sharpest drop is between 30 and 36 feet, where the mapped water sheds 77 acres.

How accurate is this Coventry 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.

Coventry Lake depth map

Coventry Lake in Coventry, Connecticut reaches a depth of 36 feet. Coventry Lake is charted here across 7 closed depth contours, from the 0 ft line down to 36 ft, enclosing about 373 acres of water. Half of that water lies inside the 24 ft line, and only 6 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Coventry Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	373 acres	100%
6 ft	297 acres	80%
12 ft	244 acres	65%
18 ft	197 acres	53%
24 ft	154 acres	41%
30 ft	83 acres	22%
36 ft	6 acres	1.6%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 373 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 Coventry Lake: steep sides for its size

The survey encloses about 373 acres of Coventry Lake inside its 0 ft contour, and half of that water lies inside the 24 ft line, so depth comes quickly here, with no long shallow margin before the bottom drops away. Between 30 and 36 ft the mapped water sheds 77 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 deepest 36 ft contour holds 6 acres, 1.6% of the mapped water, toward the southern end of the lake. Nothing here reaches a true cold-water layer at 36 ft, so structure does the thermocline's work: the points and inside turns where the 30 and 36 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Coventry Lake

At 36 ft, Coventry 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 36 ft hole, 6 acres of it, at first light, then move up onto the 30–36 ft break as the sun gets up, and fish the flats inside the 24 ft line through the middle of the day. Check ice thickness locally before you walk out.
