CARSON CITY, Nev. (AP) - Scientists are rethinking long-held assumptions about the forces that influence Lake Tahoe's health and clarity.
An annual report released Thursday shows that despite a prolonged wet and cold winter in 2010-2011, the lake's famed clarity actually improved. Such conditions are generally believed to decrease clarity.
Researchers also say that the 2007 Angora Fire on Tahoe's west short that burned more than 3,000 acres and destroyed hundreds of home has little effect on the lake's water clarity.
The 2012 State of the Lake report, funded by the University of California, Davis and the California Tahoe Conservancy, comes in advance of this year's Tahoe Summit, being held Monday at Edgewood.
