All three of China’s major rivers are flooding right now.
A dam dating back to the 50s has collapsed in guangxi province. There are actually 1000s of dilapidated dams in China dating back to Mao, which haven’t been properly maintained.
These dams are not the same design as the Three Gorges Dam (the largest dam in the world), but that dam has seen visible deformation as spotted from satellite imagery… and it’s not clear the CCP actually has the situation under control.
The Three Gorges dam started to release flood water after its reservoir rose about 50 feet above its flood line.
It just so happens that if this dam breaks, one of the cities under threat of being flooded, would be Wuhan.
