How deep is Pataconk Reservoir?

Pataconk Reservoir reaches a maximum depth of 15 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 56 acres, and half of that water sits inside the 12 ft line.

Where is the deepest part of Pataconk Reservoir?

The deepest charted water on Pataconk Reservoir lies inside the 15 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 Pataconk Reservoir is shallower than 12 feet?

About half. The 12 ft contour encloses 18 acres of the roughly 56 acres inside the outer 0 ft line, so the other half of the water is shallower than 12 feet. The sharpest drop is between 12 and 15 feet, where the mapped water sheds 18 acres.

How accurate is this Pataconk Reservoir 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.

Pataconk Reservoir depth map

Pataconk Reservoir in Chester, Connecticut reaches a depth of 15 feet. Pataconk Reservoir is charted here across 6 closed depth contours, from the 0 ft line down to 15 ft, enclosing about 56 acres of water. Half of that water lies inside the 12 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.

Pataconk Reservoir depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	56 acres	100%
3 ft	46 acres	83%
6 ft	38 acres	69%
9 ft	30 acres	54%
12 ft	18 acres	31%
15 ft	under 1 acre	under 1%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 56 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 Pataconk Reservoir: steep sides for its size

The survey encloses about 56 acres of Pataconk Reservoir inside its 0 ft contour, and half of that water lies inside the 12 ft line, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. Between 12 and 15 ft the mapped water sheds 18 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 15 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 15 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 Pataconk Reservoir

A shallow lake like Pataconk Reservoir 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 15 ft contour. Start there, then hunt the subtle single-contour depressions across the 56-acre basin. Check ice thickness locally before you walk out.
