DRAINAGE AREA.--123 mi².
PERIOD OF RECORD.--Continuous-record discharge station, October 1928 to current year. Monthly discharge only for October and November 1928, published in WSP 1302.
REVISED RECORDS.--WSP 1702: 1938. WDR NJ-76-1: 1975(M). WDR NJ-77-1: 1976.
GAGE.--Water-stage recorder with telemetry and crest-stage gage. Datum of gage is 8.10 ft above NGVD of 1929.
REMARKS.--Records good, except for estimated discharges, which are fair. Diversions by Ciba-Geigy Inc., 800 ft upstream July 1966 through 1990; the effluent was returned by pipeline directly into the Atlantic Ocean, thus bypassing station. Occasional regulation also occurs from an unknown source.
