RENO, Nev. (AP) — The clarity of Lake Tahoe's cobalt blue water improved last year from its worst level in a half-century after weather and runoff returned to more normal conditions at the alpine lake straddling the California-Nevada line.
1 / 2FILE - This April 12, 2012, file photo, shows the clarity of Lake Tahoe, Nev. The clarity of Lake Tahoe's cobalt blue water improved last year from its worst level in a half-century as weather and runoff returned to more normal conditions. Scientists say a plate-sized disc used to measure clarity was visible at an average depth of 70.9 feet in 2018, which is an improvement of 10.5 feet from 2017.
Scientists hope efforts to combat threats to clarity posed by development and climate change will eventually return Lake Tahoe to its historical clear depth of 100 feet . "In 2018, Lake Tahoe's clarity regained the expected seasonal patterns that were disrupted by the extreme conditions of the previous year," Schladow said.
"We are thrilled to see Lake Tahoe's clarity improving from the all-time low of just 60 feet in 2017," said Darcie Goodman Collins, CEO of the League to Save Lake Tahoe."These results encourage us to continue restoring critical habitat and improving our urban areas to keep pollution from entering our lake."
