Connecticut lake depth maps
Bigelow Pond depth map
Bigelow Pond in Union, Connecticut reaches a depth of 15 feet. Bigelow Pond is charted here across 6 closed depth contours, from the 0 ft line down to 15 ft, enclosing about 25 acres of water. Half of that water lies inside the 9 ft line, and only 2.9 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 |
|---|---|---|
| 0 ft | 25 acres | 100% |
| 3 ft | 21 acres | 85% |
| 6 ft | 18 acres | 72% |
| 9 ft | 10 acres | 42% |
| 12 ft | 7.1 acres | 29% |
| 15 ft | 2.9 acres | 12% |
Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 25 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 Bigelow Pond: steep sides for its size
About 25 acres of Bigelow Pond sit inside the survey's 0 ft contour, and half of that water is already gone by the 9 ft line: the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. The steepest break on the chart runs from 6 down to 9 ft: 8 acres of bottom fall away across 3 ft there, which makes that band the first contour to work. 2.9 acres, 12% of the mapped water, lie inside the deepest 15 ft contour, toward the southwestern corner of the lake. Topping out at 15 ft, weed growth structures this water more than depth does, but the 2.9-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 Bigelow Pond
A shallow lake like Bigelow Pond 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 2.9 acres inside the 15 ft contour. Start there, then hunt the subtle single-contour depressions across the 25-acre basin. Check ice thickness locally before you walk out.
Bigelow Pond depth map FAQs
- How deep is Bigelow Pond?
- Bigelow Pond reaches a maximum depth of 15 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 25 acres, and half of that water sits inside the 9 ft line.
- Where is the deepest part of Bigelow Pond?
- The deepest charted water on Bigelow Pond lies inside the 15 ft contour, toward the southwestern corner of the lake. That contour encloses 2.9 acres, 12% 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 Bigelow Pond is shallower than 9 feet?
- About half. The 9 ft contour encloses 10 acres of the roughly 25 acres inside the outer 0 ft line, so the other half of the water is shallower than 9 feet. The sharpest drop is between 6 and 9 feet, where the mapped water sheds 8 acres.
- How accurate is this Bigelow Pond 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.
