I produced a TV series episode about this lake in 2010 and learned that Jacques Cousteau once took a submergable to the depths of this glacial water. It is said that he would not reveal to anyone about what he saw, which might likely be well preserved bodies of Chinese laborers from the railroad days.
What was the name of the series and what was the episode?
Or maybe some kind of prehistoric lake monster (named 'Tessie' ;^)...
I recall the same about Cousteau - he saw many bodies, they go down, and at a certain depth depending on their weight they are static do not decompose just stay there floating nothing is there to decompose them.
What he saw were bodies from mob killings dumped with concrete shoes from the 50’s into the lake.
