Details

The Slenderhead Darter prefers medium-sized creeks to large rivers with strong flow and gravel, rubble, or bedrock riffles. It is common in the Des Moines, Cedar and Wapsipinicon drainages in Iowa. Throughout its range the slenderhead remains common, although siltation from agricultural practices has covered the gravel riffles of many of our streams, eliminating the species locally.

Questions remain about the spawning activities of this species, but it is believed it occurs in late May to mid-June over gravel riffles.

Recent stream sampling information is available from Iowa DNR's biological monitoring and assessment program.
