Range:

Notes:

-- Definition -- An approximation of mean low water adopted as the reference level for a limited region, irrespective of better determinations later. -- Description -- SOURCE [DFDD]. NOTE Used mostly in harbour and river engineering. Used in inland waters. It is generally defined as a level which the daily mean water level would fall below less than 5 percent of the time and by no more than 0.2 metres during the navigation season. A single level surface is usually chosen as the low water datum for a whole lake. On a river, low water datum is a sloping surface, which approximates the surface of the river at a low state.

-- Definition -- An approximation of mean low water that has been adopted as a standard reference for a limited area. -- Description -- SOURCE [Based on DFDD]. NOTE 1 It is retained for an indefinite period regardless of the fact that it may differ slightly from a better determination of mean low water from a subsequent series of observations. NOTE 2 Used primarily for river and harbor engineering purposes.
