Water temperature and specific conductance continuously recorded at station for the National Water-Quality Assessment Program.

EXTREMES FOR PERIOD OF RECORD.--
SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 19,000 ft³/s, Oct. 4, 1926, gage height, 18.50 ft, from graph based on gage readings, site then in use; maximum gage height, 19.06 ft, Apr. 13, 1994, discharge, 15,900 ft³/s; no flow Aug. 28, Sept. 5, 11, 17, 18, Oct. 30, 31, Nov. 1, 1988.

REMARKS FOR CURRENT YEAR.--Benthic macroinvertebrate community samples were collected as part of the National Water-Quality Assessment program (NAWQA) in the lower Illinois River Basin. One quantitative (Richest-Targeted Habitat) and one qualitative (Qualitative-Multiple Habitat) sample were collected in accordance with the NAWQA protocols (Cuffney and others, 1993). The quantitative sample was a composite of macroinvertebrates from about 10 submerged tree branches. Branches were cut underwater, gathered in a 425µm mesh net, and invertebrates were washed or picked from the branches. The average length and average diameter of each branch were measured and used to calculate an approximate surface area. The qualitative sample was collected from many habitat types within the sampling reach to obtain as complete a list of invertebrate taxa as possible. All samples were processed by the USGS National Water-Quality Laboratory. Phylum, Class, Order, Suborder, Family, Subfamily, and Tribe are listed and arranged according to the USGS National Water-Quality Laboratory taxonomic hierarchy. Reach A begins 820 ft upstream of the gage, and continues upstream for 915 ft. Reach B begins 2227 ft upstream of the gage, and continues upstream for 579 ft. Reach C begins 2719 ft upstream of the gage, and continues upstream for 633 ft. The surface area sampled at reach A was 0.21 m², at reach B was 0.22 m², and at reach C was 0.15 m².
