A.

High water mark is the level that the water got to, so if you marked 
that it would be a high water mark marker....

Have you thought about using something like man_made=flood_mark? Similar 
to man_made=survey_point 
(https://wiki.openstreetmap.org/wiki/Tag:man_made%3Dsurvey_point).

Historic suggests that the flood mark is interesting because it is old. 
Some flood marks are certainly old and interesting:

Others are quite new:

Does it have to be flood_mark:type=*? Would flood_mark=* be adequate?
