For the last five months of 2022, Lake Tahoe was the clearest it has been since the 1980s. That is due in part to a resurgence of the lake's native zooplankton. It's provided a natural cleanup crew to help restore the lake's famous blue waters. The findings are reported in the Lake Tahoe Clarity Report 2022, released a few weeks ago by the UC Davis Tahoe Environmental Research Center. Director Geoffrey Schladow tells how the lake first lost its clarity, and then how nature righted itself.
