Authorities were searching today for a missing swimmer at Lake Mead, National Park Service spokeswoman Christie Vanover said.The man was reported missing at 11:52 a.m. after he jumped off of a houseboat to swim to shore with others, she said.
He was last seen swimming in the area of Sandy Cove, she said. It is unclear whether the man was wearing a life jacket.
He is the third swimmer to go missing at Lake Mead this week.
