Keeping Tahoe very blue: Lake Tahoe’s clarity improved by over 10 feet last year

Lake Tahoe’s water clarity improved in 2018 mainly due to a typical winter season and water flow on rivers and streams, according to a new study.

Scientists measure clarity by lowering a 10-inch white disk into the water and noting the depth at which it become invisible. They took 26 readings from January through December in 2018.
