Bluegrass Lake depth map

Bluegrass Lake in Warrick County, Indiana reaches a depth of 65 feet. Bluegrass Lake is charted here across 4 closed depth contours, from the 25 ft line down to 50 ft, enclosing about 43 acres of water. Half of that water lies inside the 40 ft line, and only under an acre 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 43 acres inside the outermost charted contour (the 25 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. The survey also records a 65 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Bluegrass Lake: steep walls and a big basin

About 43 acres of Bluegrass Lake sit inside the survey's 25 ft contour, and half of that water is already gone by the 40 ft line: depth comes quickly here, with no long shallow margin before the bottom drops away. The steepest break on the chart runs from 35 down to 40 ft: 20 acres of bottom fall away across 5 ft there, which makes that band the first contour to work. Inside the 50 ft contour there is under an acre of water, toward the western side of the lake: a single pocket rather than a basin, and worth a drift over in high summer. 65 ft of water makes this a two-story fishery: warm-water fish hold the 25-to-40 ft ground while the basin can stay cold below the summer thermocline, and the traffic between the two runs along the 35–40 ft break at first and last light.

Bluegrass Lake depth map FAQs

How deep is Bluegrass Lake?
Bluegrass Lake reaches a maximum depth of 65 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 4 closed depth contours over about 43 acres, and half of that water sits inside the 40 ft line. The 65 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 50 ft.
Where is the deepest part of Bluegrass Lake?
The deepest charted water on Bluegrass Lake lies inside the 50 ft contour, toward the western side of the lake. That contour encloses under an acre, 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 Bluegrass Lake is shallower than 40 feet?
About half. The 40 ft contour encloses 1.8 acres of the roughly 43 acres inside the outer 25 ft line, so the other half of the water is shallower than 40 feet. The sharpest drop is between 35 and 40 feet, where the mapped water sheds 20 acres.
How accurate is this Bluegrass 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.
