A California man was killed when he was swept down a waterfall on Lake Tahoe's western shore, authorities said Monday.

"We don't know if he jumped or slipped, but he ended up in the creek at the top of the falls," said ranger Brian Barton of Lake Tahoe State Park. "He was unable to get out of the water and he went over the falls."

The victim's name was withheld pending notification of family members. He died Sunday after being swept 40 to 60 feet down Eagle Falls at Emerald Bay, Barton said.

Similar accidents have occurred at Eagle Falls in the past, the ranger said. The spring runoff now is near its peak after another unusually snowy winter in the Sierra.
