How deep is Billings Lake?

Billings 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 99 acres, and half of that water sits inside the 12 ft line.

Where is the deepest part of Billings Lake?

The deepest charted water on Billings Lake lies inside the 30 ft contour, toward the northeastern corner of the lake. That contour encloses 1.1 acres, 1.2% 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 Billings Lake is shallower than 12 feet?

About half. The 12 ft contour encloses 40 acres of the roughly 99 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 31 acres.

How accurate is this Billings 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.

Billings Lake depth map

Billings Lake in North Stonington, Connecticut reaches a depth of 30 feet. Billings Lake is charted here across 6 closed depth contours, from the 0 ft line down to 30 ft, enclosing about 99 acres of water. Half of that water lies inside the 12 ft line, and only 1.1 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Billings Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	99 acres	100%
6 ft	68 acres	69%
12 ft	40 acres	41%
18 ft	34 acres	34%
24 ft	25 acres	25%
30 ft	1.1 acres	1.2%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 99 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 Billings Lake: an evenly graded bottom

Inside its outermost 0 ft contour the survey charts about 99 acres of Billings Lake, with the 12 ft line enclosing half of it, so the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. The sharpest change on the chart is between 0 and 6 ft, where the mapped water loses 31 acres in 6 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 30 ft contour holds 1.1 acres, 1.2% 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 Billings Lake

At 30 ft, Billings 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, 1.1 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.
