**NOTICE: The New Jersey Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news


ALL DATA ARE AT LOCAL TIME


USGS 01409146 East Thorofare at Ship Bottom, NJ

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text
During winter months, cold and ice may result in inaccurate real-time tide elevation data. Adjustments or deletions of this data can only be done after detailed analysis.

 


SURFACE-WATER RECORDS

LOCATION.--Lat 39°39'15", long 74°11'09" referenced to North American Datum of 1983, Ship Bottom Borough, Ocean County, NJ, Hydrologic Unit 02040301, on south side of bridge carrying State Route 72 across East Thorofare (Manahawkin Bay) between Bonnet Island and Long Beach Island, 2.0 mi southeast of Bayside, 9.0 mi southwest of Barnegat Inlet, and 11.5 mi northeast of Little Egg Inlet.
PERIOD OF RECORD.--Unpublished fragmentary gage-height record, July 1997 to May 5, 2000. Continuous-record tide gage, May 5, 2000 to current year. Continuous-record discharge gage April 2012 to current year.
GAGE.--Acoustic Doppler velocity meter, acoustic stage sensor, temperature sensor, and tide elevation recorder with telemetry and tidal crest-stage gage. Datum of gage is at 0.00 ft NAVD of 1988. To determine approximate elevations to NGVD of 1929, add 1.25 ft.
REMARKS.--GAGE HEIGHT: Periods of missing data are noted by dashed (---) lines. DISCHARGE: Records fair, except for estimated daily discharges, which are poor. Streamflow at this site is significantly affected by astronomical tides. Daily mean discharges were computed from filtered unit value discharge data. The Godin low-pass filter is used to remove principal tidal frequencies from unit values. Positive discharge (ebb tide) is generally to the south direction, and negative discharge (flood tide) is generally to the north. Extremes were computed from unfiltered unit value discharges.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 6.4 ft, Oct 29, 2012, from high water mark; minimum elevation, -2.49 ft, Feb 19, 2013, although a lower tide likely occurred during a period of missing record on Feb 16, 2007. DISCHARGE: Maximum positive discharge (unfiltered), 49,300 ft3/s, Oct 29, 2012; maximum negative discharge (unfiltered), -82,200 ft3/s, Oct 29, 2012.

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.

This station managed by the New Jersey Water Science Center.
