well, there is also problem what is man-made, see http://sk.wikipedia.org/wiki/Po%C4%8D%C3%BAvadlianske_jazero which is man made lake build in 16th century. so with the on the ground truth it's quite impossible to destinguish from natural lakes or http://www.freemap.sk/?c=core.gallery.view.22 which even I can rember being made. but it's still a lake. to be honest I cannot find a single lake within 20km radius, which is purely natural. > http://wiki.openstreetmap.org/wiki/Key:water > > Personally, I'd vote for removing the double tagged water=lake;pond since > it's redundant and should be one or the other, not both, and ensuring that > each feature had a natural=water tag.
