How deep is Pataganset Lake?

Pataganset Lake 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 127 acres, and half of that water sits inside the 12 ft line.

Where is the deepest part of Pataganset Lake?

The deepest charted water on Pataganset Lake lies inside the 30 ft contour, toward the northeastern corner of the lake. That contour encloses 8.1 acres, 6.3% 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 Pataganset Lake is shallower than 12 feet?

About half. The 12 ft contour encloses 56 acres of the roughly 127 acres inside the outer 0 ft line, so the other half of the water is shallower than 12 feet. The sharpest drop is between 0 and 6 feet, where the mapped water sheds 43 acres.

How accurate is this Pataganset 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.

Pataganset Lake depth map

Pataganset Lake in East Lyme, Connecticut reaches a depth of 30 feet. Pataganset Lake is charted here across 6 closed depth contours, from the 0 ft line down to 30 ft, enclosing about 127 acres of water. Half of that water lies inside the 12 ft line, and only 8.1 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Pataganset Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	127 acres	100%
6 ft	84 acres	66%
12 ft	56 acres	44%
18 ft	35 acres	28%
24 ft	17 acres	14%
30 ft	8.1 acres	6.3%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 127 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 Pataganset Lake: an evenly graded bottom

The survey encloses about 127 acres of Pataganset Lake inside its 0 ft contour, and half of that water lies inside the 12 ft line, so the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. Between 0 and 6 ft the mapped water sheds 43 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 8.1 acres, 6.3% of the mapped water, toward the northeastern corner 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 Pataganset Lake

At 30 ft, Pataganset 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 30 ft hole, 8.1 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 12 ft line through the middle of the day. Check ice thickness locally before you walk out.
