How deep is Roseland Lake?

Roseland Lake 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 96 acres, and half of that water sits inside the 12 ft line.

Where is the deepest part of Roseland Lake?

The deepest charted water on Roseland Lake lies inside the 18 ft contour, toward the middle of the lake. That contour encloses 6.6 acres, 6.9% 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 Roseland Lake is shallower than 12 feet?

About half. The 12 ft contour encloses 40 acres of the roughly 96 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 20 acres.

How accurate is this Roseland 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.

Roseland Lake depth map

Roseland Lake in Woodstock, Connecticut reaches a depth of 18 feet. Roseland Lake is charted here across 7 closed depth contours, from the 0 ft line down to 18 ft, enclosing about 96 acres of water. Half of that water lies inside the 12 ft line, and only 6.6 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Roseland Lake depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	96 acres	100%
3 ft	79 acres	82%
6 ft	68 acres	71%
9 ft	55 acres	57%
12 ft	40 acres	42%
15 ft	20 acres	21%
18 ft	6.6 acres	6.9%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 96 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 Roseland Lake: steep sides for its size

Inside its outermost 0 ft contour the survey charts about 96 acres of Roseland Lake, with the 12 ft line enclosing half of it, so depth comes quickly here, with no long shallow margin before the bottom drops away. The sharpest change on the chart is between 12 and 15 ft, where the mapped water loses 20 acres in 3 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 18 ft contour holds 6.6 acres, 6.9% of the mapped water, toward the middle of the lake. At 18 ft top to bottom, weed growth shapes this water more than depth does, but the 6.6-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 Roseland Lake

Shallow water like Roseland Lake is usually among the first to make safe ice, and with only 6.6 acres inside the 18 ft contour the fish have very little deep water to spread into once the weed beds die back. That hole, and the subtle single-contour depressions across the 96-acre basin, are where to start. Check ice thickness locally before you walk out.
