The datum of gage has been determined to be 0.00 feet above NAVD 1988 and .30 feet above NGVD 1929. To obtain water-surface elevation values in NAVD 1988 add 0.00 feet to gage height values. Prior to October 1, 2016 the datum of gage was 0.00 feet above NAVD 1929.
Data are tidally affected -- Astronomical tides cause significant cycles of approximately 24.84 hours at this site. Because a different portion of the 24.84-hour tidal cycle is averaged in successive daily (24-hour) computations, a systematic secondary oscillation, unrelated to basin hydrology and having a period of about two weeks may be apparent in daily data. |
