Where Are Catfish Found?

Two of the main catfish species -- channel and flathead -- have wide distribution in the U.S. and are among the most popular of fish for anglers to target. Government agencies also have stocked catfish in some areas in an attempt to expand their range. You can find catfish in lakes, rivers and streams.

  1. Range

    • In North America, the native channel catfish range, according to Texas Parks and Wildlife, is between an area roughly bounded by the Rocky Mountains and the Appalachian Mountains. They also have been introduced into waters outside of that area, including some in California. Flathead catfish can be found in a more limited range, primarily in the watershed of the Mississippi River.

    Spawning Time

    • Both channel and flathead catfish spawn when the water temperature where they live reaches about 75 F. The spawn sends them into predictable, but secluded, areas. Cavities in logs are likely places to find spawning catfish, as are thick piles of driftwood and undercut banks.

    Rivers

    • Flathead and channel catfish are often found in rivers, though both prefer areas without much current. Some of the most likely places to find catfish in rivers are in deep holes, among floating piles of driftwood and other snags, undercut banks and spots where the river channel swings one way or another. The fish move away from these areas and onto rocky or sandy spots at night to feed.

    Schooling Activity

    • Channel catfish often can be found swimming in large schools. Flathead catfish, however, tend to live a more solitary life. In general, one flathead occupies a prime piece of habitat, whether that be a downed tree or the space beneath an undercut bank. The exception is at night, when they move out of such areas and swim into other areas to feed.
