I am not sure what the term "natural" means. If a woman makes a depression in the terrain, and it automatically fills up with (surface or ground) water because of the geological conditions, is this "natural" or not? What about a woman sealing the terrain and conducting water to a place where there wasn't a water body before? This is a flooded open pit mine, is it "natural" or not, and if not, what would be the osm tag for it? water=lake, natural=no? https://www.lmbv.de/files/LMBV/Fotos/Nachrichten/Archivierte%20Nachrichtenfotos/LMBV_1616.jpg What about a lake without water (drained)? Is "lake" a term that can only be used for water bodies, or are dry lakes ok? Example: https://www.openstreetmap.org/#map=13/41.9975/13.5625 (everything "yellow" is a lake / former lake (actually third largest lake in Italy): https://en.wikipedia.org/wiki/Fucine_Lake > - water=fountain > - water=fishpond > -1 to "fishpond". It is not defined in the wiki, and is discouraged as likely a mistake: https://wiki.openstreetmap.org/wiki/Key:water (and I agree it is not good). You can have fish in many kinds of water bodies, I just recently started to add fish=yes to fountains when there are fish inside. > > And as mentioned before, there are water=reservoir (A reservoir > <https://en.wikipedia.org/wiki/Reservoir> or an artificial lake is used > to store water. ) > what about artificial lakes that are not for storing water?
