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 quantitative sample was collected in accordance with NAWQA protocols (Cuffney and others, 1993). Reach A is located 512 ft downstream of the the 1100 N Road bridge (which is 2.5 stream miles downstream of the gage), and continues downstream for 820 ft which includes the area next to the gaging station.
