EXTREMES FOR PERIOD OF RECORD.--
SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 22,900 ft³/s, Feb. 21, 1951, gage height, 20.90 ft, from rating curve extended above 8,200 ft³/s; maximum gage height, 28.16 ft, Apr. 12, 1994, discharge, 19,400 ft³/s; minimum discharge, 2.0 ft³/s, Sept. 1, 2, 7, 1972, Oct. 8, 1994.

REMARKS FOR CURRENT YEAR.--Algae community samples were collected as part of the National Water-Quality Assessment program (NAWQA) in the upper 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. 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.
