During winter months, cold and ice may
result in inaccurate real-time gage height and streamflow data.
Adjustments or deletions of this data can only be done after detailed

SURFACE-WATER RECORDS
LOCATION.--Lat 40°53'25", long 74°04'50"
referenced to North American Datum of 1983, Lodi Borough, Bergen
County, NJ, Hydrologic Unit 02030103, on left bank 560 ft upstream from
bridge on Outwater Lane in Lodi, 1.3 mi south of Rochelle Park, and 3.2
mi upstream from mouth.
DRAINAGE AREA.--54.6 mi².
PERIOD OF RECORD.--Continuous-record discharge station,
September 1923 to current year.
REVISIONS HISTORY.--WSP 781: Drainage area. WSP 1031: 1940(M).
WSP 1552: 1929(M), 1936(M), 1938. WDR NJ-1969: 1967. WDR NJ-1970: 1968,
1969. On June 18, 2020 peak streamflow for the 2015 water year
was revised.
GAGE.--Water-stage recorder with telemetry. Concrete control
since Nov 2, 1938. Datum of gage is 25.00 ft above NGVD of 1929. Prior
to Nov 2, 1938, at site 560 ft downstream at datum 2.54 ft lower.
REMARKS.--Records good, except for estimated discharges, which
are fair. Diurnal fluctuations at low flow probably due to patterns of
sewage effluent entering river upstream. Diversion from river upstream
at Paramus by United Water New Jersey, for municipal supply. The flow
past this station may be affected by pumpage from wells by United Water
New Jersey and others. The river was channelized upstream in Paramus
around 1966.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 5,330 ft³/s,
Sep 17, 1999, gage height, 13.94 ft, from high-water mark in gage
house; minimum discharge, 1.0 ft³/s, May 25, 1935.
WATER-QUALITY RECORDS
PERIOD OF RECORD.--Water years 1962 to current year.
PERIOD OF DAILY RECORD.--DISSOLVED OXYGEN: July-August 2008,
August-September 2009. DISSOLVED OXYGEN, OF PERCENT SATURATION:
July-August 2008, August-September 2009. pH: July-August 2008,
August-September 2009. SPECIFIC CONDUCTANCE: July-August 2008,
August-September 2009. WATER TEMPERATURE: July-August 2008,
August-September 2009.
REMARKS.--Discrete water-quality data were collected as part of
the
New Jersey Ambient Surface-Water-Quality Monitoring Network.
