RENO, Nev. (AP) - Scientists at Lake Tahoe say continued improvement in the clarity of the mountain waters has convinced them that regulating land use and taking other steps to protect the lake are paying off.
Researchers at the UC Davis Environmental Research Center said Wednesday last year's clarity improved more than 6 feet from 2011, to an average depth of 75.3 feet.
That's the best it's been since 2002 when the white plate used to measure clarity was visible as deep as 78 feet.
Scientists say the alpine lake's azure waters were clear enough to see more than 100 feet down back in 1968 before development accelerated in the Tahoe Basin.
UC Davis researcher Geoffrey Schladow says there's growing belief in the scientific community that it's possible to manage Tahoe for clarity.
