How deep is Maltby Lake #1?

Maltby Lake #1 reaches a maximum depth of 18 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 7 closed depth contours over about 19 acres, and half of that water sits inside the 6 ft line.

Where is the deepest part of Maltby Lake #1?

The deepest charted water on Maltby Lake #1 lies inside the 18 ft contour, toward the northeastern 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 Maltby Lake #1 is shallower than 6 feet?

About half. The 6 ft contour encloses 9 acres of the roughly 19 acres inside the outer 0 ft line, so the other half of the water is shallower than 6 feet. The sharpest drop is between 0 and 3 feet, where the mapped water sheds 5 acres.

How accurate is this Maltby Lake #1 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.

Maltby Lake #1 depth map

Maltby Lake #1 in West Haven, Connecticut reaches a depth of 18 feet. Maltby Lake #1 is charted here across 7 closed depth contours, from the 0 ft line down to 18 ft, enclosing about 19 acres of water. Half of that water lies inside the 6 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.

Maltby Lake #1 depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	19 acres	100%
3 ft	14 acres	74%
6 ft	9 acres	48%
9 ft	4.4 acres	24%
12 ft	2.1 acres	11%
15 ft	under 1 acre	2.3%
18 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 19 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 Maltby Lake #1: an evenly graded bottom

The survey encloses about 19 acres of Maltby Lake #1 inside its 0 ft contour, and half of that water lies inside the 6 ft line, so the bottom falls away at a steady rate rather than shelving off or dropping in one step. Between 0 and 3 ft the mapped water sheds 5 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 18 ft contour, toward the northeastern 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 18 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 Maltby Lake #1

A shallow lake like Maltby Lake #1 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 18 ft contour. Start there, then hunt the subtle single-contour depressions across the 19-acre basin. Check ice thickness locally before you walk out.
