Answer 1

Answer 2

Once again, questions like these require basic research :-)
I found this:
"Water can't flow out of the Salton Sea, so it escapes only by evaporation, which leaves behind salts and other minerals. The water is 30 percent saltier than the Pacific Ocean. In fact, this man-made disaster of a lake has gotten so salty that scientists say it now threatens some of the birds that rely on it."
