China had open the flood gates and was using spillways which had some problems to try to save the 3G Dam. I also read that they evacuated a bunch of people and then blew up a dam to hopefully save the 3G dam.
How would blowing up another dam save the 3G dam?
It it is downstream from 3G it would have no effect. If it is upstream it would make things worse.
It would have to be part of the 3G dam system but only have a limited flow. Opening the shipping locks might qualify but that is risky. They might get jammed open.
