Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

GAGE - U.S. Army Corps of Engineers water-stage recorder, satellite telemeter, acoustic-velocity meter, and crest-stage gage. Auxiliary U.S. Army Corps of Engineers water-stage recorder and satellite telemeter at site 8.6 mi downstream. Datum of gage is 427.17 ft above NAVD of 1988. Prior to Oct. 1, 1940, nonrecording gage at same site at datum 1.65 ft higher. Oct. 1, 1940, to Mar. 31, 1942, nonrecording gage at present site and datum. Prior to Oct. 30, 1967 and Nov. 9, 1999 to Oct. 29, 2002, auxiliary water-stage recorder at mouth of Copperas Creek, 8.0 mi downstream.
REMARKS - Occasional regulation at low flow by navigation dams at Peoria and La Grange. Since Jan. 17, 1900, flow has included diversion from Lake Michigan through Chicago Sanitary and Ship Canal.
Accuracy of records is discussed in the annual Station Analysis archived at the USGS IL Water Science Center.
EXTREMES FOR PERIOD OF RECORD - SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 101,000 ft³/s, estimated based on graphic reconstruction, Sept. 20, 2008, gage height, 24.68 ft; maximum gage height, 26.54 ft, April 24, 2013, discharge, 79,800 ft³/s; minimum daily discharge, 600 ft³/s, Oct. 26, 1997, estimated, caused by dam regulation.
