The Salton Sea isn’t comparable to The Aral Sea. The Aralsk island was where a soviet bio weapons lab was located. Anthrax, weaponized smallpox, and god only knows what other bio horrors.
It is comparable the main difference is that we had a a nuclear test lab instead of a biolab.
there was a lost atomic bomb, and many planes, tonnes of tungsten, and today tons of chemicals and pesticides from agricultural runoff.
I read of plans to try and fix it, but who knows if that will ever happen.
they could easily build a dual pipeline to the ocean one sucking water and one pushing ocean water into the sea. (the sea is saltier than the ocean currently)
