GAGE.-- U.S. Army Corps of Engineer's water-stage recorder and satellite telemeter, and crest-stage gage. Datum of gage is 418.00 ft above NGVD of 1929 (levels by U.S. Army Corps of Engineers) (417.65 ft NAVD 1988). Prior to Nov. 25, 1992 and Oct. 1, 1994 to current; auxiliary gage (05585500) at site 10.0 mi upstream. Nov. 25, 1992 to Sept. 30, 1994; auxiliary gage operated at this site (05586100).

 

REMARKS.-- Occasional regulation at low flow by navigation dam at La Grange. Since Jan. 17, 1900, flow has included diversion from Lake Michigan through Chicago Sanitary and Ship Canal. Suspended-sediment samples were collected by local observers generally twice weekly with additional samples collected during high runoff periods. Since February 1994, samples used to compute sediment record have been collected at upstream side Rt. 106 bridge at Florence at mile 56.

 

EXTREMES FOR PERIOD OF RECORD.--

SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 123,000 ft3/s, May 26-28, 1943; maximum gage height, 28.61 ft, May 26, 1943; minimum daily discharge, 1,330 ft3/s, Sept. 2, 1984.

SUSPENDED-SEDIMENT CONCENTRATIONS: Maximum daily, 3,720 mg/L, Apr. 14, 1981; minimum daily, 14 mg/L, Dec. 26, 1984, July 21, 1993.

SUSPENDED-SEDIMENT LOADS: Maximum daily, 410,000 tons, June 4, 1980; minimum daily, 172 tons, Sept. 2, 1984.

 

REMARKS FOR CURRENT YEAR.--Sampled as part of the Lower Illinois River Basin (LIRB) National Water Quality Assessment Program (NAWQA).
