How deep is Lake Hayward?

Lake Hayward reaches a maximum depth of 33 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 12 closed depth contours over about 175 acres, and half of that water sits inside the 12 ft line.

Where is the deepest part of Lake Hayward?

The deepest charted water on Lake Hayward lies inside the 33 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 Lake Hayward is shallower than 12 feet?

About half. The 12 ft contour encloses 57 acres of the roughly 175 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 3 feet, where the mapped water sheds 37 acres.

How accurate is this Lake Hayward 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.

Lake Hayward depth map

Lake Hayward in East Haddam, Connecticut reaches a depth of 33 feet. Lake Hayward is charted here across 12 closed depth contours, from the 0 ft line down to 33 ft, enclosing about 175 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.

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 175 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 Lake Hayward: an evenly graded bottom

About 175 acres of Lake Hayward sit inside the survey's 0 ft contour, and half of that water is already gone by the 12 ft line: the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. The steepest break on the chart runs from 0 down to 3 ft: 37 acres of bottom fall away across 3 ft there, which makes that band the first contour to work. Inside the 33 ft contour there is under an acre of water, toward the southeastern corner of the lake: a single pocket rather than a basin, and worth a drift over in high summer. Nothing here reaches a true cold-water layer at 33 ft, so structure does the thermocline's work: the points and inside turns where the 0 and 3 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Lake Hayward

At 33 ft, Lake Hayward is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 33 ft hole, 0.8 acres of it, at first light, then move up onto the 0–3 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.
