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.

Taylor, Illinois Natural History Survey, Champaign. Reach A begins 36 feet downstream of Cottage Grove Bridge and continues downstream for 656 feet. |
