Earlier this year, we got some encouraging news about Lake Tahoe. Scientists, who for a generation have documented a loss of over 30 feet of water clarity at the Lake, were able to say with certainty that the rate of decline has slowed. Since 2001, they said, the long-term downward trend of continuous decline has flattened. Being the expert scientists they are, the group stopped short of speculating on a cause for this positive trend. Having conducted a more sophisticated analysis than has been available in the past, however, they stated definitively that for a period of seven years, something was changing.
