REMARKS FOR CURRENT YEAR.--Fish community samples were collected as part of the National Water-Quality Assessment program (NAWQA) in the upper 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). Collections were made with a single pass of the entire reach with a barge or a backpack electroshocker with supplementary seine hauls and kicks. Fishes were identified by C. A. Taylor, Illinois Natural History Survey, Champaign. Reach A begins 144 feet upstream of Somonauk Road and continues upstream for 591 feet. |
