At least 60 families with vacation properties along the picturesque shores were given 24 hours to vacate their homes that are situated on federal land.

"They are all vacation homes and everybody who lives in them are considered visitors," said Christie Vanover, spokeswoman for the Lake Mead Recreational Area.

"If anybody needs to gather their personal belongings, we’re not going to deny them access. They can go do that. They just can’t spend the nights there or have barbecues during the day," Vanover said.
