DRAINAGE AREA.--77.9 mi².
PERIOD OF RECORD.--Occasional miscellaneous discharge measurements, water years 1954, 1973. Continuous-record discharge station, May 1998 to current year.
REVISED RECORDS.--WDR NJ-03-1: 1998 (M), 2003. WDR NJ-04-1: 2003 (M)
GAGE.--Water-stage, velocity, and precipitation recorder with telemetry and crest-stage gage. Datum of gage is 34.18 ft above NAVD of 1988.

The water temperature data for this station are temporary and will only be displayed for 120 days. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
