The bigger issue is that while the water still exists, it may no longer exist in a useful location. It could be pulled from a reservoir in a drought stricken area, evaporate and drift to some other area where it causes a flood.
That’s an extreme example, but I hope it makes the point that the location of water is just as important as its existence.
