REMARKS FOR CURRENT YEAR.-- Fish community samples were collected as part of the National Water-Quality Assessment program (NAWQA), in the lower Illinois River Basin. Taxonomy is based on Robins and others (1991), except where modified for the family Moronidae (Johnson, 1984) and the order Cyprinidontiformes (Parenti, 1981). Common names were compared to the current Illinois fish species list posted by Illinois Natural History Survey. Collection methods followed Meador and others (1993). Collections were taken with seines. Fishes were identified in the field by C. A. Taylor, Illinois Natural History Survey, Champaign. Representative specimens were preserved, identified, and vouchered at the Illinois Natural History Survey fish collection. Reach A begins 66 feet upstream of the gage, and continues upstream for 459 feet.
