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 average of all the low water heights observed over the National Tidal Datum Epoch.

Mean low water or “MLW” means the average height of all low water above Chart Datum;
