Big Barbee depth map
Big Barbee in Indiana reaches a depth of 42 feet. Big Barbee is charted here across 39 closed depth contours, from the 4 ft line down to 42 ft, enclosing about 229 acres of water. Half of that water lies inside the 23 ft line, and only 1.9 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 229 acres inside the outermost charted contour (the 4 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 Big Barbee: an evenly graded bottom
The survey encloses about 229 acres of Big Barbee inside its 4 ft contour, and half of that water lies inside the 23 ft line, so the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. Between 24 and 25 ft the mapped water sheds 12 acres in 1 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. The deepest 42 ft contour holds 1.9 acres, under 1% of the mapped water, toward the northern end of the lake. Nothing here reaches a true cold-water layer at 42 ft, so structure does the thermocline's work: the points and inside turns where the 24 and 25 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.
Ice fishing on Big Barbee
At 42 ft, Big Barbee is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 42 ft hole, 1.9 acres of it, at first light, then move up onto the 24–25 ft break as the sun gets up, and fish the flats inside the 23 ft line through the middle of the day. Check ice thickness locally before you walk out.
Big Barbee depth map FAQs
- How deep is Big Barbee?
- Big Barbee reaches a maximum depth of 42 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 39 closed depth contours over about 229 acres, and half of that water sits inside the 23 ft line.
- Where is the deepest part of Big Barbee?
- The deepest charted water on Big Barbee lies inside the 42 ft contour, toward the northern end of the lake. That contour encloses 1.9 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 Big Barbee is shallower than 23 feet?
- About half. The 23 ft contour encloses 113 acres of the roughly 229 acres inside the outer 4 ft line, so the other half of the water is shallower than 23 feet. The sharpest drop is between 24 and 25 feet, where the mapped water sheds 12 acres.
- How accurate is this Big Barbee 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.
