Yeah, as I understand it Banqiao Dam was/is quite similar - it was also necessary in order to prevent much more regular and disruptive downstream flooding, and its collapse was a direct consequence of holding back too much water out of fear of downstream flooding (as well as some unfortunate design flaws). It also served as a water supply. That doesn't stop nuclear proponents regularly pointing to its failure as evidence that nuclear is safer than hydroelectric.

I suspect there might be a bias towards high-profile dam failures in China involving hydroelectric dams because the larger dams obviously get more attention and were also more economically viable to incorporate hydroelectric power into.
