§ 2.05-27 - Waters subject to tidal influence; waters subject to the ebb and flow of the tide; mean high water.

Waters subject to tidal influence and waters subject to the ebb and flow of the tide are interpreted as waters below mean high water. “Mean high water” is the average of the height of the diurnal high water at a particular location measured over a lunar cycle period of 19 years. These terms do not include waters above mean high water caused by flood flows, storms, high winds, seismic waves, or other non-lunar phenomena.
