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.
This tide gage is operated as part of the New Jersey Tide Telemetry System. The system is cooperatively funded by the State of New Jersey and the USGS.
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.

downstream from tide gate, 0.3 mi downstream from bridge over
Waackaack Creek on Laurel Avenue, and 1.3 mi east of Union
PERIOD OF RECORD.--Unpublished fragmentary gage-height record, September 1997 to October 2000. Continuous-record tide gage, November 2000 to current year.
GAGE.--Water-stage, air temperature, water temperature, wind speed and direction, barometric pressure, and precipitation recorder. Datum of gage is at 0.00 ft NAVD of 1988. To determine approximate elevations to NGVD of 1929 datum, add 1.18 ft.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation recorded, 5.46 ft, Dec 25, 2002. Minimum recorded elevation, -5.76 ft, Dec 12, 2000.
EXTREMES OUTSIDE PERIOD OF RECORD.--Maximum known elevation, 7.9 ft (adjusted to NAVD of 1988), Nov 25, 1950, from high-water mark in Keansburg (prior to installation of flood gate), published in the report "Tidal Flood Plain Information - Sandy Hook Bay and Raritan Bay Shore Areas, Monmouth County, New Jersey, July 1972," by the U.S. Army Corp of Engineers.
