Don't know if it's a real movie happening or not. Someone sent it to me. But I'd guess it's probably about the dark history of the lake and the lost towns below. Some folks say it's haunted. Sadly, enough people die there every year...
Expedition unknown with Josh Gates did a thing on the lake last year. “Lake of the dead”Pretty creepy stuff. You can find it on discovery or Nat geo. Forget which one.
