(abbreviated LW; or low tide) The lowest limit of the surface water level reached by the lowering tide Low water is caused by the astronomic tide-producing forces and/or the effects of meteorological, hydrologic and/or oceanographic conditions
The minimum height reached by a falling tide The low water is due to the periodic tidal forces and the effects of meteorological, hydrologic, and/or oceanographic conditions For tidal datum computational purposes, the minimum height is not considered a low water unless it contains a tidal low water
Minimum height reached by a falling tide The height may be due solely to the periodic tidal forces or it may have superimposed upon it the effects of meteorological conditions
The minimum height reached by each falling TIDE Nontechnically, also called LOW TIDE
