Indiana lake depth maps

Nyona Lake depth map

Nyona Lake in Fulton County, Indiana reaches a depth of 30 feet. Nyona Lake is charted here across 6 closed depth contours, from the 5 ft line down to 30 ft, enclosing about 85 acres of water. Half of that water lies inside the 15 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 85 acres inside the outermost charted contour (the 5 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 Nyona Lake: an evenly graded bottom

The survey encloses about 85 acres of Nyona Lake inside its 5 ft contour, and half of that water lies inside the 15 ft line, so the bottom falls away at a steady rate rather than shelving off or dropping in one step. Between 10 and 15 ft the mapped water sheds 26 acres in 5 ft of depth, the sharpest change on the chart, start on that band, because it is where the bottom stops being flat. The 30 ft contour, toward the eastern side of the lake, encloses under an acre of water, a single pocket rather than a basin, but one worth a drift over in high summer. With 30 ft at its deepest there is no true cold-water layer here, so structure does the work the thermocline does elsewhere: fish the points and inside turns where the 10 and 15 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Nyona Lake depth map FAQs

How deep is Nyona Lake?
Nyona Lake reaches a maximum depth of 30 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 6 closed depth contours over about 85 acres, and half of that water sits inside the 15 ft line.
Where is the deepest part of Nyona Lake?
The deepest charted water on Nyona Lake lies inside the 30 ft contour, toward the eastern 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 Nyona Lake is shallower than 15 feet?
About half. The 15 ft contour encloses 41 acres of the roughly 85 acres inside the outer 5 ft line, so the other half of the water is shallower than 15 feet. The sharpest drop is between 10 and 15 feet, where the mapped water sheds 26 acres.
How accurate is this Nyona 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.
