Lake Tahoe Basin — The waters of Lake Tahoe were clear to an average depth of 72.4 feet in 2005, according to UC Davis scientists who have monitored the lake since 1968. That keeps the clarity measurement in the range where it has been for the past five years — and where it was for other multi-year periods in the 1990s.
