Long-term impacts of water quality and climate variability on Illinois River waterway fish assemblages
The Illinois River has been heavily altered by a range of human activities. Among these, wetlands have been drained, lock and dams constructed, navigation channels maintained, and industrial effluent and sewage discharged. These alterations have strongly affected fish assemblages within the river. …
