The basic goal of recent clean water legislation is to restore and maintain the chemical, physical, and biological integrity of the nation's waters. A research program was initiated to evaluate the role of physical habitat in regulating the structure of fish communities in warmwater streams in east-central Illinois. An empirical approach involving observations of fish in relatively natural conditions was combined with studies of stream areas that have been subjected to extensive modification by human society. This report is a summary of the work relating to this research.
