Indeed not all flood marks are really old/historic. But that threshold 
is probably very fuzzy.

Looking at one of you examples 
(https://www.flickr.com/photos/23954094@N05/9701630002) I realized that 
Frank (and probably many others) call it "Flood high water marks".

So basic tag for mark could be
flood_mark=(yes, plaque, pole, painted, ...),
just to avoid flood_mark:type=*.
And additionally, features with historical value can get 
historic=highwater_mark. Makes it sense?

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

Great hint - thanks!
