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
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Unpublished fragmentary gage-height record,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
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.
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.
