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 394 ft downstream of the Greenwood Road bridge (1.43 mi upstream of gaging station), and continues downstream for 525 ft. | |
