Peak Flow and Stage Information

Station Picture

Elevation (observed) and tide elevation (predicted) for this station are reported to NGVD 1929. To convert data to NAVD 1988 subtract 1.19 ft. To convert data to MLLW datum subtract 0.25 ft. These corrections vary from site to site.

NGVD 1929 is the National Geodetic Vertical Datum of 1929, formerly called "mean sea level" or "Sea Level Datum of 1929." NGVD 1929 was a general adjustment of the first-order level nets fit to mean sea level at 26 tide gages in the US and Canada.
NAVD 1988 is the North American Vertical Datum of 1988, which is a geodetic datum derived from a general adjustment of the first-order level nets fit to 1 tide gage in eastern Canada.
MLLW is mean lower low water, which is a site-specific datum determined by averaging the lowest of the 2 low tides that occur each day over a 19-year tidal epoch. For tide gages with less than 19 years of record, this datum is estimated by correlation with long-term tide gages.
