How deep is Wonoscoponuc Lake?

Wonoscoponuc Lake reaches a maximum depth of 100 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 11 closed depth contours over about 347 acres, and half of that water sits inside the 50 ft line.

Where is the deepest part of Wonoscoponuc Lake?

The deepest charted water on Wonoscoponuc Lake lies inside the 100 ft contour, toward the middle of the lake. That contour encloses 1.5 acres, 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 Wonoscoponuc Lake is shallower than 50 feet?

About half. The 50 ft contour encloses 135 acres of the roughly 347 acres inside the outer 0 ft line, so the other half of the water is shallower than 50 feet. The sharpest drop is between 10 and 20 feet, where the mapped water sheds 46 acres.

How accurate is this Wonoscoponuc 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.

Wonoscoponuc Lake depth map

Wonoscoponuc Lake in Salisbury, Connecticut reaches a depth of 100 feet. Wonoscoponuc Lake is charted here across 11 closed depth contours, from the 0 ft line down to 100 ft, enclosing about 347 acres of water.

Depth contour	Water inside it	Share of mapped water
0 ft	347 acres	100%
10 ft	304 acres	88%
20 ft	258 acres	74%
30 ft	217 acres	63%

100 ft	1.5 acres	under 1%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 347 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 Wonoscoponuc Lake: a stepped drop into deep water

Inside its outermost 0 ft contour the survey charts about 347 acres of Wonoscoponuc Lake, with the 50 ft line enclosing half of it, so the bottom steps down contour by contour into the deep basin rather than shelving flat or plunging all at once. The sharpest change on the chart is between 10 and 20 ft, where the mapped water loses 46 acres in 10 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 1.5 acres, under 1% of the mapped water, lie inside the deepest 100 ft contour, toward the middle of the lake. At 100 ft this is two-story water: the basin can stay cold below the summer thermocline while warm-water fish stay up on the 0-to-50 ft ground, and the fish that move between the two do it along the 10–20 ft break at first and last light.

Ice fishing on Wonoscoponuc Lake

Deep water like Wonoscoponuc Lake freezes later and less evenly than the shallow lakes around it, and the winter bite sets up on the first real break, not out over the 100 ft hole. That edge is the 10–20 ft band on the chart above, where 46 acres of bottom tilt away, and panfish and walleye work up and down it through the day. By late ice the fish push back onto the 0-to-50 ft flat. Check ice thickness locally before you walk out.
