LOCATION.--Lat 41°36'51", long 87°43'46", in SE1/4NW1/4 sec.15, T.36 N., R.13 E., Cook County, Hydrologic Unit 07120003, on right bank at downstream side of bridge on Kilbourn Avenue in Oak Forest, and at mile 5.9.

DRAINAGE AREA.--12.6 mi2.

PERIOD OF RECORD.--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).

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

GAGE.--Water-stage recorder. Datum of gage is 620.41 ft above sea level (Cook County Highway Department bench mark).

REMARKS.--Records good except those for estimated daily discharges, which are poor. 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 the recession. Flow bypassed gage from Nov. 21, 1962, to Mar. 2, 1963, due to diversion 1.0 mi upstream. Gage-height telemeter at station.
