How deep is Norwich Pond?

Norwich Pond reaches a maximum depth of 30 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 30 acres, and half of that water sits inside the 24 ft line.

Where is the deepest part of Norwich Pond?

The deepest charted water on Norwich Pond lies inside the 30 ft contour, toward the middle of the lake. That contour encloses 9.3 acres, 31% of the mapped water, so it is a broad slice of the bottom rather than a pinpoint target, the depth chart above gives the contour to line up on.

How much of Norwich Pond is shallower than 24 feet?

About half. The 24 ft contour encloses 14 acres of the roughly 30 acres inside the outer 0 ft line, so the other half of the water is shallower than 24 feet. The sharpest drop is between 0 and 6 feet, where the mapped water sheds 6 acres.

How accurate is this Norwich Pond 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.

Norwich Pond depth map

Norwich Pond in Lyme, Connecticut reaches a depth of 30 feet. Norwich Pond is charted here across 6 closed depth contours, from the 0 ft line down to 30 ft, enclosing about 30 acres of water. Half of that water lies inside the 24 ft line, and only 9.3 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Norwich Pond depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	30 acres	100%
6 ft	24 acres	80%
12 ft	21 acres	69%
18 ft	17 acres	58%
24 ft	14 acres	47%
30 ft	9.3 acres	31%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 30 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 Norwich Pond: steep sides for its size

The survey encloses about 30 acres of Norwich Pond 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 0 and 6 ft the mapped water sheds 6 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 30 ft contour holds 9.3 acres, 31% of the mapped water, toward the middle of the lake. Nothing here reaches a true cold-water layer at 30 ft, so structure does the thermocline's work: the points and inside turns where the 0 and 6 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Norwich Pond

At 30 ft, Norwich Pond is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 30 ft hole, 9.3 acres of it, at first light, then move up onto the 0–6 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.
