The 3 Gorges Dam is giving way.
I'm sure that you are somewhat aware of the situation for the Chinese dam. Here is just one note to remember.
"Jun 23, 2020 - Wang wrote in a 2019 article that the dam is composed of dozens of independent concrete blocks. “These blocks are not connected to the bedrock below, they're just sitting on top it,” wrote Wang. He said if the dam collapses, it will impact over 400-million people living downstream."

The dam is not connected to the bedrock. How the Chinese thought they could get away with this is hard to fathom. The dam already has a curve in it. The blocks are shifting.
The rain is falling so hard that they have had to open all the penstocks. The water level is 2 meters above maximum. The same must be true for the pressure also.

Just to give you some perspective, the Oroville dam is 1/3 of a mile thick.
