My boyfriend told me (and I don’t know if it’s true) that there’s a lake in Arizona where people have been dumping dead bodies for hundreds of years because, apparently, due to the water’s qualities the bodies will sink easily. He said that indigenous tribes have been doing that for ages, as well as mobs. Apparently a famous scuba diver went down there and he cancelled the investigation because he said something along the lines of “the world isn’t ready to see what’s down there” Is there any truth to this?
Does he know the name of the lake? Can he at least tell you the source he heard it from? The name of the supposedly famous scuba diver?
If he can't name a single source (and there doesn't seem to be anything on the Internet), then it sounds like run of the mill rumors/ghost stories.
I think you might be talking about Lake Tahoe which isn't in Arizona, but instead on the California-Nevada border. The lake has cold temperatures that cause bodies to not decompose normally and there have been a few instances of bodies being found years later. There have also been rumors or the mob using it as well as it being a dumping ground for Chinese immigrants that helped construct the railroads, but none of those rumors have been verified. I would recommend checking out this article as it goes into a lot more depth than I have.
As the other person mentioned, unless you can provide more details it's hard to verify what you're talking about.
That’d appear to be Lake Tahoe and the diver Jacques Costeu, who is quite famous for his conservation efforts, however the anecdote appears to be nothing more than rumour.
“Other versions name the filmmaker as Jacques Cousteau, who is reported to have said "the world is not ready" for what is down there or, alternately, "a stop was quickly put on the mission by some powerful people."
Former Nevada state historian Guy Rocha wrote in 2006 in the Reno Gazette-Journal:
"The truth is that Philippe Cousteau, Jacques' grandson, visited Lake Tahoe in April 2002, but there is no record of Jacques seeing the jewel of the Sierra, much less his being involved in an underwater expedition."”
