File - In this Feb. 15, 2016, file photo, a stand-up paddleboarder glides across Lake Tahoe at sunset in California. An annual report on Lake Tahoe said the United States' largest alpine lake is still warming at 14 times the historic average. The finding is in the yearly report released Thursday, July 27, 2017, by the University of California at Davis on the state of Lake Tahoe, which straddles the California and Nevada borders.
