SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 3,540 ft3/s, Aug. 17, 1987, gage height, 10.54 ft; minimum, no flow, May 27, 1998, due to bridge construction. | |
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, lat 41°49'41.60", long 87°54'28.40", is located 187 ft upstream of the walking bridge (0.63 mi upstream from gage) in the Bemis Woods west of Wolf Road and north of Ogden Avenue; it continues upstream for 984 ft. Reach B is 1663 ft upstream of walking bridge, and continues upstream for 948 ft. Reach C is located 328 ft downstream of the walking bridge and continues downstream for 984 ft. |
