How we know
- 149lakes where a DNR fisheries survey caught them
A lake can appear in more than one line. A lake that isn’t listed may still have them: records exist only where someone caught, netted or stocked them.
Inland lakes on this list run from 6 to 3,508 acres (median 80) and from 6 to 125 ft deep (median 34 ft).
How many turn up in DNR surveys
Indiana DNR crews survey lakes the same way everywhere: timed night electrofishing along the shore, plus gill and trap nets set overnight. The standard method makes lakes comparable. These are the DNR’s own sampling rates from its community surveys, 2008–2025 — a measure of how many fish a lake holds, not how many an angler will catch.
- Found in
- 129 of 170 lakes surveyed this way
- Typical rate
- 1.2 per net lift where found
- Highest
- 13.8 per net lift
- Method
- fish per net lift (gill and trap nets)
“Typical” is the median across the lakes where the survey caught at least one. Nets and electrofishing catch different fish: by the other method it turned up in 126 lakes at a typical 8.0 per hour of electrofishing. A single survey is a snapshot of one season.

How to recognize it
A very large mouth for a sunfish, red eyes, and dark stripes running from the eye across the cheek to the ear flap. The ear flap is small with a red border, and the pectoral fins are short and rounded. It can change quickly from light to dark brown.

Life in an Indiana lake
Warmouth are secretive fish of clear, shallow water with dense rooted plants โ natural lakes, sluggish streams, oxbows and marshes โ hiding among stumps, brush and weeds.
Unlike most sunfish they don't nest in colonies: each male fans out a nest beside a rock, stump or clump of plants and guards the eggs and young.

Rules and eating
Check the rules before you keep fish. Each lake page shows the regulations that apply there, and the Indiana Fishing Guide is the official source. Before eating fish from a particular lake, check the Indiana Fish Consumption Advisory.
