How we know

  • 12lakes 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 38 to 3,508 acres (median 163) and from 8 to 90 ft deep (median 66 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.

“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 6 lakes at a typical 0.50 per net lift. A single survey is a snapshot of one season.

How to recognize it

Dark vertical bars on a brown or bronze body, and a jaw that reaches the eye but not past its rear edge. Young smallmouth have orange in the center of the tail.

Don’t confuse it with

Largemouth bass — The jaw reaches past the rear of the eye, and a dark stripe runs along the side.

Smallmouth bass: the upper jaw ends below the eye, not past it; the dorsal fin is joined by a shallow notch; dark vertical bars on bronze-brown sides.
Illustration of a largemouth bass's head and front half from the side, mouth closed, with the upper jaw reaching past the back of the eye, a deep notch between the two parts of the dorsal fin, and a dark band along the side.
Largemouth bass: the upper jaw reaches past the back of the eye; the dorsal fin is almost split in two; a dark band runs along the side.

Life in an Indiana lake

Smallmouth are fish of gravel- and rock-bottomed streams with current; in lakes they favor steep drop-offs and rocky shores.

The male builds a nest on gravel or hard bottom and guards the eggs and fry for a short time; the young feed on zooplankton and midge larvae.
