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 analysis.

LOCATION.--Lat 39°18'25", long 74°49'14" referenced to North American Datum of 1983, Upper Township, Cape May County, NJ, Hydrologic Unit 02040302, on right bank at highway bridge on State Route 49, 0.2 mi upstream from McNeals Branch, 0.4 mi southeast of Head of River, and 3.7 mi west of Tuckahoe.
DRAINAGE AREA.--30.8 mi².
PERIOD OF RECORD.--Continuous-record discharge station, December 1969 to current year.
REVISED RECORDS.--WDR NJ-89-1: 1986(M). WDR NJ-91-1: 1990. WDR NJ-97-1: 1971(M), 1978(M), 1979(M), 1983 (P), 1994(P). WDR US-2008: 1996(M), 1998(M). WDR US-2009: 1975(M), 1976(M).
GAGE.--Water-stage recorder with telemetry monitors stage above and below wooden control. Water-stage recorder below control since October 2003. Tidal crest-stage gage below control. Datum of gage is 0.00 ft NGVD of 1929.
REMARKS.--Records good, except for estimated discharges, which are fair. Occasional regulation by ponds above station. Stage-discharge relationship can be affected by variable-stage backwater from tide. The water-stage recorder below control at station is used when variable stage backwater conditions exist.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 1,340 ft³/s, Aug 22, 1997, gage height, 9.09 ft; minimum discharge, not determined.

National Weather Service flood stage for this gage is 6 ft.

The air 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.
