Is there any?

I think it would be cool if such a thing exists. Flooded due to rising sea levels, or demolition of a dam.

None mentioned in any source if I recall. But there are also a few numbers missing...so maybe...

There are a few vaults in NV that were partially flooded, but I *think* that was internal water reserve leakage or something.

With fallout 4's large focus on the ocean we may end up getting this or something similar.
