Upgraded Measuring Standard Improves Accuracy of Water Level Data

The South Florida Water Management District (SFWMD) is upgrading the reference system used to measure water elevations. Water elevation readings, also known as water level readings, will soon be reported in the newer North American Vertical Datum of 1988 (NAVD 88) instead of the National Geodetic Vertical Datum of 1929 (NGVD 29).
