Mean low water definition

Mean low water means the average low tide. An approximation of mean low-water is made by observing the low-water mark when the tide height is at 0.0 feet as indicated on a tide table.

Mean low water means the arithmetic mean of the low water heights observed over a specific 19-year metronic cycle (National Tidal Datum Epoch) as defined by the National Oceanic and Atmospheric Administration. For purposes of these Rules, an approximation of mean-low water made by observation of low tide during a 0.00 foot tide will generally be sufficient.

Mean low water means the average height of the low waters over a 19- year period. For shorter periods of observation, “mean low water” means the aver- age height of low waters after corrections are applied to eliminate known variations and to reduce the result to the equivalent of mean 19-year value.
