Consider that sea water is only 96.5% H2O on average, and some natural salt lakes are over 30% salts: these are mapped as natural=water + water=lake + salt=yes - https://en.wikipedia.org/wiki/Hypersaline_lake
I'm of similar mind with Joseph that landuse=industrial isn't ideal here but rather is something I would characterize as applicable to the whole area, like the areas surrounding BOTH a mine (tagged landuse=quarry) and its tailing ponds (however tagged, but not exclusively with landuse=industrial).
I'm of similar mind with Joseph that these are "largely water" and it isn't wrong to say so, although the tag natural=water is jarring, as tailing ponds are anything but natural. Possibly another tag that has "water" in it as a key or value? (Please, not natural).
Again, do we now take this discussion (as requested) to the https://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Tailing_pond ? Seems appropriate, rather than extending this thread in this list.
