Six stations were sampled for water chemistry, fish population and instream habitat. Based on these data, environmental quality was evaluated using various indices, including water quality (WQI), fish community (IBI) and instream habitat (PIBI). Each station was rated for degree of use support of aquatic life and classified according to the Biological Stream Characterization System used for Illinois streams.
