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. 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.
