* Lake Tahoe never freezes due to the constant mass movement of water from the bottom to the surface.
In February 1989, Emerald Bay froze over for the first time since 1952.
* The Panama Canal (700 feet in width and 50 feet in depth) could be filled by Lake Tahoe's water and extend completely around the earth at the equator, with enough remaining in the lake to fill another channel of the same width and depth running from San Francisco to New York.
* An average 1,400,000 tons of water evaporates from the surface of Lake Tahoe every 24 hours, yet this drops the lake level only one-tenth of an inch.
* Lake Tahoe is as long as the English Channel is wide with the width of Tahoe being half again as wide as San Francisco Bay.
