Click to hidestation-specific text



LOCATION.--Lat 40°11'21", long 74°45'21" referenced to North American Datum of 1983, Trenton City, Mercer County, NJ, Hydrologic Unit 02040201, on concrete wall facing west over the Delaware River, near Trenton Marine Terminal on Lamberton Road, approximately 0.2 mi south of the intersection with State Route 29.
PERIOD OF RECORD.--Continuous-record tide station, water years 1921-46, 1951-55, 1957-92, 2019 to current year. Annual maximum tide gage, water years 1997-2018.
REVISIONS HISTORY.--WDR US-2010: 1997-2009(M).
GAGE.--Tide elevation and water temperature recorders with telemetry and tidal crest-stage gage. Datum of gage is at 0.00 ft NAVD of 1988. Prior to October 1996, datum of gage was at 0.00 ft NGVD of 1929. Data published to NGVD of 1929 can be adjusted to NAVD of 1988 by subtracting 1.05 ft. Online peaks have been adjusted to current datum.
REMARKS.--Periods of missing data are noted by dashed (---) lines. Annual peak stages at this gage may be due to riverine or tidal conditions.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 16.8 ft (adjusted to NAVD of 1988), Aug 20, 1955.


Water Temperature: October 2018 to current year. 
REMARKS.--The accuracy of continuous water-quality data can be found here.
EXTREMES FOR PERIOD OF RECORD.--WATER TEMPERATURE: Maximum, 24.0°C, first occurring on September 23, 2019 at 1654 with multiple occurrences; minimum, 0.0°C, first occurring on January 21, 2019 at 2254 with multiple occurrences.

Weather station data are available from this location at this link.

The weather 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.

This station managed by the New Jersey Water Science Center.
