Tioga Lake, located along Highway 120 west near the east entrance to Yosemite, will be drained one month earlier this year for necessary maintenance.
In compliance with the Federal Energy Regulatory Commission (FERC) and Inyo National Forest conditions, Southern California Edison (SCE) began draining the lake on Tuesday in order to install a geomembrane liner on the main and auxiliary Tioga Lake dams.
It is expected to take two to three weeks to drain the lake and while there will still be some water in the lake, recreation will be limited.
