Important Change in River Level Measurements

Beginning on November 1, 2016, the District started using a new vertical datum, the North American Vertical Datum of 1988 (NAVD88). In the past, the District has used the National Geodetic Vertical Datum of 1929 (NGVD29). The new datum results in a downward shift of between 0.64 to 0.90 feet depending on location. There is no change in the actual river level, only the value used to represent the level is different.

More information about the vertical datum change may be found at http://www.mysuwanneeriver.com/VerticalDatum or by calling the District offices at 386-362-1001 and asking to speak with Tom Mirti, Director of Water Resources.
