Green Valley Lake depth map

Green Valley Lake in Vigo County, Indiana reaches a depth of 21 feet. Green Valley Lake is charted here across 6 closed depth contours, from the 3 ft line down to 18 ft, enclosing about 37 acres of water. Half of that water lies inside the 12 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.

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 37 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. The survey also records a 21 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.

Fishing Green Valley Lake: steep sides for its size

Inside its outermost 3 ft contour the survey charts about 37 acres of Green Valley Lake, with the 12 ft line enclosing half of it, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. The sharpest change on the chart is between 6 and 9 ft, where the mapped water loses 9 acres in 3 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 2.9 acres, 7.8% of the mapped water, lie inside the deepest 18 ft contour, toward the western side of the lake. Topping out at 21 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.

Green Valley Lake depth map FAQs

How deep is Green Valley Lake?
Green Valley Lake reaches a maximum depth of 21 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 37 acres, and half of that water sits inside the 12 ft line. The 21 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 18 ft.
Where is the deepest part of Green Valley Lake?
The deepest charted water on Green Valley Lake lies inside the 18 ft contour, toward the western side of the lake. That contour encloses 2.9 acres, 7.8% 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 Green Valley Lake is shallower than 12 feet?
About half. The 12 ft contour encloses 13 acres of the roughly 37 acres inside the outer 3 ft line, so the other half of the water is shallower than 12 feet. The sharpest drop is between 6 and 9 feet, where the mapped water sheds 9 acres.
How accurate is this Green Valley 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.
