DRAINAGE AREA.-- 12.6 mi2.
 

PERIOD OF RECORD.--

SURFACE-WATER DISCHARGE AND STAGE
 

DISCHARGE: October 1950 to current year. Prior to October 1974, records published with those for streams in the St. Lawrence River basin (WSP 1307, 1727, 1911, 2111, WDR-IL 1971-74).
 

STAGE: Water years 1994 to current year.
 

REVISED RECORDS.-- WSP 1337: 1951-53: WSP 1911: Drainage area.
 

GAGE.-- Water-stage recorder and phone telemeter. Datum of gage is 620.41 ft above NGVD of 1929 (Cook County Highway Department bench mark).
 

REMARKS.-- Diurnal fluctuation at low flow caused by small industrial plants upstream. Retention pond 1.0 mi upstream detains water during periods of heavy runoff and gradually releases water during recessions. Flow bypassed gage from Nov. 21, 1962, to Mar. 2, 1963, due to diversion 1.0 mi upstream.
 

EXTREMES FOR PERIOD OF RECORD.--

SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 627 ft3/s, Apr. 22, 1973, gage height, 7.67 ft; maximum gage height, 9.00 ft, July 13, 1957, discharge, 550 ft3/s; no flow at times in most years.
 

REMARKS FOR CURRENT YEAR.-- Records good except those for estimated daily discharges, which are poor.
