Lake Tahoe’s water continues to show some of the murkiest levels on record, according to a new report from UC Davis. Readings from 2020 put the average depth of Tahoe’s water clarity at 62.9 feet, on par with 2019’s average of 62.7 feet but down a substantial 8 feet from the year before. The 2019 and 2020 data show the lake near its lowest level of clarity since UC Davis researchers began keeping records 53 years ago. The worst year was 2017, when lake clarity measured 59.7 feet.
