climate change?
Trump’s fault
Depletion of fresh water used to level the locks. Big fresh water lake that citizens depend on for drinking water and agriculture, which hasn’t been filling up lately due to el nino. My first thought was, well then pump in sea water at the locks to level them. But that makes sense. Anyway, it’s a long discussion, explores the prospect of alternatives, gets into the history of it all.
Unfortunately, it takes the whole “climate change” thing as a given. Personally, I think we should be so lucky. If it were true, it would be wonderful. But I don’t think it is.
