Lake Tahoe’s water level is less than 8″ from it’s maximum legal limit today.

The runoff season has just begun, so look for water levels to increase through the coming weeks.

  •  If you were to pour Lake Tahoe out onto an area the size of California, the water would still be 14 inches (36 cm) deep.

Lake Tahoe’s water level is controlled at the Tahoe City Dam, its only outlet.  The legal limit for water above the natural rim at that dam is 6,229.1′. Tahoe’s current water level is at 6,228.43′, only 8″ below the legal limit.

Squaw Valley saw 715″ of snowfall this season – they average 450″ of snowfall.

In the past 30 years, Lake Tahoe has fluctuated between 6,220.26′ and 6.229.39′.  That high mark being the 1997 flood.

In December 2016, Lake Tahoe was sitting at only 6,223.04′.
