The following correction factor should be applied:

	Feet	Meters
NAVD 88 Correction Term (Subtract from Database Sonde Value)	4.73	1.44
EXAMPLE: Given a water height reading from the sonde of 5.25 feet (1.6 meters) the following calculation can be made: Water Height = Sonde Water Height - NAVD 88 Correction Term 1.6 meters (5.25ft) - 1.44 meters (4.73 ft) = 0.16 meters (0.52 ft) RESULT: 0.16 meters (0.52 ft) Relative to NAVD 88 Datum

Note:All archive depth data is reported in meters.
