DRAINAGE AREA - 68.5 mi².
REVISIONS HISTORY - WYS-US-2015: 1997. Revisions subsequent to Water Year 2014 can be obtained by using this link.
PERIOD OF RECORD - Low-flow partial-record station water years 1963-69, 1973, 1979-96. November 1992 to September 1996 (gage height and discharge measurements only). Continuous-record gaging station, October 1996 to current year.
GAGE - Water-stage, velocity (from 2005 to current), and water temperature recorder with telemetry and crest-stage gage. Datum of gage is 161.61 ft above NAVD of 1988.
REMARKS - Records fair, except for estimated discharges, which are poor. Flow includes sewage effluent from several treatment plants upstream of gage.

PERIOD OF RECORD - Water years 1963 to current year.
REMARKS - Discrete water-quality data were collected as part of the New Jersey Ambient Surface-Water-Quality Monitoring Network.
