Why doesn t Lake Tahoe freeze over?

Experts say it won't freeze this year and likely never has in human memory. That's because Lake Tahoe is deep — very deep. At 1,645 feet, it is the second-deepest lake in the United States. Before a lake can freeze, the water from top to bottom has to lose heat built up in the warmer months.
