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 a boat electroshocker and seine. 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. The reach begins 2001 feet upstream of the Towerline Road bridge and continues upstream for 1099 feet.
