LAKE TAHOE, Calif./Nev. – Scientists and researchers have been watching the clarity of Lake Tahoe for decades, rejoicing when one can see almost 100 feet down into the iconic body of water, sadness when clarity drops to record levels.
The clarity of the lake is an important indicator of the changing conditions of Lake Tahoe.
In 2019, Lake Tahoe’s clarity decreased nearly eight feet from the previous year’s dramatic 10-foot improvement. The average clarity in 2019 was 62.7 feet, the second-lowest on record. In 2017, the recorded clarity was 60 feet. In 1968, it was 102 feet.
