Did you know… It would take 700 years to naturally refill an empty Lake Tahoe?

If Lake Tahoe’s volume of 39 trillion gallons were somehow emptied from the Basin, it would take an estimated 700 years for snowmelt, precipitation and runoff from Tahoe’s 63 tributary streams to fill the lake to its current levels, according to gotahoenorth.com.

Those 63 creeks and streams carry an average of 101 billion gallons of water annually into Lake Tahoe, according to krnv.iewatershed.com.

The 15-mile long Upper Truckee River, Trout, Taylor, Ward, and Blackwood creeks carry more than a half of the yearly volume of water into the lake.

Tahoe’s watershed drains 506 square miles, compared to the lake’s 193 square-mile surface area.
