How deep is Loon Lake?

Loon Lake reaches a maximum depth of 65 feet, according to the Indiana DNR Lake Bathymetry survey. Most of the lake is shallower, with 13 mapped depth bands between the shoreline and the deepest hole.

Where is the deepest part of Loon Lake?

The deepest surveyed water on Loon Lake sits toward the western side of the lake, inside the 65 ft contour. The interactive depth map above shows the full basin outline and the breaks leading into it.

How accurate is this Loon Lake depth map?

The contours come from the Indiana DNR Lake Bathymetry survey. 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.

How to fish Loon Lake: deep, two-story water

At 65 feet, this is a two-story fishery: warm-water species work the shallows and weed edges while the deep basin can hold cold-water fish below the summer thermocline. In summer, target the transition where the bottom breaks from the shallow shelf toward the basin; fish suspend along that edge at dawn and dusk. The 13 mapped depth bands make it straightforward to find those breaks before you launch.

Ice fishing on Loon Lake

On deep water like Loon Lake, the winter bite concentrates along the first major drop-off rather than the deepest basin. Use the contours above to find where the shallow shelf breaks toward deep water and set up on that edge; panfish and walleye slide up and down it through the day. Late ice often pushes fish shallower again. Always verify ice thickness locally before walking out, and remember deep lakes freeze later and less evenly than shallow ones.
