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

SURFACE-WATER RECORDS
LOCATION.--Lat 39°06'39", long 74°44'03"
referenced to North American Datum of 1983, Avalon Borough, Cape May
County, NJ, Hydrologic Unit 02040302, on fishing pier at east end of
Old Avalon Boulevard, 0.5 mi east of bridge carrying County Route 601
(Avalon Boulevard) over Ingram Thorofare, 1.0 mi west of Avalon, 1.0 mi
southwest of Townsends Inlet, and 1.6 mi east of Upper Island in Great
Sound.
NOTE: The pier and well have a fence surrounding them since the pier
was closed as of August, 2016. The well can still be accessed.
PERIOD OF RECORD.--Continuous-record tide gage, October 1977 to
May 1978, May 13, 2000 to current year. Annual maximum tide, water
years 1979 to 1981, 1984 and 1993. Unpublished fragmentary gage-height
record, May 1997 to May 2000.
GAGE.--Tide elevation and water temperature 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 1.29
ft. From October 1977 to May 1978, tide level recorder located 200 ft
south of current station and datum of gage at 0.00 ft NGVD of 1929.
From 1978 to 1981, tidal crest-stage gage located 200 ft south of
current station and datum of gage at 0.00 ft NGVD of 1929. Data
published to NGVD of 1929 can be adjusted to NAVD of 1988 by
subtracting 1.29 ft. Online annual tidal peaks have been adjusted to
current datum.
REMARKS.--Gage cannot measure tide elevation below -4.15 ft or
above 3.85 ft. Tide elevations below -4.15 ft and above 3.85 ft have
been estimated. Periods of missing data are noted by dashed (---)
lines.
EXTREMES FOR PERIOD OF RECORD.--Maximum elevation, 7.15 ft, from
crest-stage gage, Oct 29, 2012; minimum elevation, undetermined, likely
occurred Feb 17, 2007 as indicated by nearby reference gages.

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.
