LAKE TAHOE (CBS/AP) – Scientists say Lake Tahoe’s clarity has improved for the second straight year, although they warn that climate change is still taking a toll on the waters.
The University of California, Davis released its annual “Tahoe: State of the Lake” report Wednesday. Scientists have been monitoring the lake’s clarity since 1968, when a white disk could be seen as far as 102.4 feet underwater.READ MORE: Storm Watch: Evacuation Orders Issued for CZU Burn Zones in Santa Cruz County
Researchers found that figure was 75.3 feet in 2012, a 6.4-foot improvement over 2011. They chalked that up to drier conditions that sent fewer pollutants into the lake, among other things.READ MORE: Police Activity Temporarily Shuts Highway 17 Saturday Afternoon
