REMARKS FOR CURRENT YEAR.--Algae community samples were collected as part of the National Water-Quality Assessment program (NAWQA) in the lower Illinois River Basin. A qualitative sample was collected in accordance with NAWQA protocols (Cuffney and others, 1993). The qualitative periphyton sample is a composite of all samples collected from all periphyton microhabitats present within the sampling reach. All samples were processed by the Philadelphia Academy of Natural Sciences. The reach begins 1326 ft downstream of the State Highway 61 bridge, and continues downstream 1283 ft.
