Flood marks and high water marks are not necessarily the same thing. Read https://en.wikipedia.org/wiki/High_water_mark to get the gist. There are ordinary high water marks (and I suppose also the opposite, ordinary low water marks) which are based on the regular tides in the area. A flood mark would be a marker for the water level reached in certain, particular events. I am not sure about terminology in different jurisdictions, but the concept seems to be clear to me that there are two different things we want to tag.
