The Danube River's water is dropping so low that World War II ships are emerging

Here in Buenos Aires we removed a lot of sunk ships from https://en.wikipedia.org/wiki/Matanza_River (a small river on the side of the city, not the huge main river) to increase water flow and try to reduce the huuuuuuuge contamination.

Good idea. You should do that.
