IMHO natural=water is flawed, for several reasons: it is not a
geographical feature (that would be natural=lake, etc.), but it is
also practically used for all kinds of superficial water (and if one
insists on "natural=from mother nature": water is almost always
"natural", the rare cases of "artificial" water aren't probably
something that will be tagged in OSM). There is an attempt to further
specifiy natural=water with a key water=? (where one of the values is
reflection_pool IIRR)

wouldn't use this for a fountain.

if you want to be generic like this, natual=water is your tag IMHO. If
you are interested in a particular feature, additionally tag this
(e.g. amenity=fountain, water_well, ...)

well, a fountain might consist of parts covered with water and others
made of rock, metal or s.th. else, and there might even be no water at
all (any more), e.g. here is a nice monumental fountain by famous
architect Bernini in a small town that was destroyed (and remained
ruins since then) in 1799 by the French:
