Worster Lake depth map
Worster Lake in St. Joseph County, Indiana reaches a depth of 18 feet. Worster Lake is charted here across 6 closed depth contours, from the 3 ft line down to 18 ft, enclosing about 267 acres of water. Half of that water lies inside the 12 ft line, and only 11 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

| Depth contour | Water inside it | Share of mapped water |
|---|---|---|
| 3 ft | 267 acres | 100% |
| 6 ft | 212 acres | 79% |
| 9 ft | 145 acres | 54% |
| 12 ft | 65 acres | 24% |
| 15 ft | 35 acres | 13% |
| 18 ft | 11 acres | 4.1% |
Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 267 acres inside the outermost charted contour (the 3 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 Worster Lake: steep sides for its size
Inside its outermost 3 ft contour the survey charts about 267 acres of Worster 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 9 and 12 ft, where the mapped water loses 80 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 11 acres, 4.1% of the mapped water, toward the southwestern corner of the lake. At 18 ft top to bottom, weed growth shapes this water more than depth does, but the 11-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 Worster Lake
Shallow water like Worster Lake is usually among the first to make safe ice, and with only 11 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 267-acre basin, are where to start. Check ice thickness locally before you walk out.
Worster Lake depth map FAQs
- How deep is Worster Lake?
- Worster Lake reaches a maximum depth of 18 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 267 acres, and half of that water sits inside the 12 ft line.
- Where is the deepest part of Worster Lake?
- The deepest charted water on Worster Lake lies inside the 18 ft contour, toward the southwestern corner of the lake. That contour encloses 11 acres, 4.1% 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 Worster Lake is shallower than 12 feet?
- About half. The 12 ft contour encloses 65 acres of the roughly 267 acres inside the outer 3 ft line, so the other half of the water is shallower than 12 feet. The sharpest drop is between 9 and 12 feet, where the mapped water sheds 80 acres.
- How accurate is this Worster Lake depth map?
- The contours come from the Indiana DNR 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. Per Indiana DNR, the data are graphical representations for reference only, not a survey instrument. Acreages are computed from the published contour geometry, not from a separate area survey, so read them as close approximations.
