Lake Tahoe

Lake Tahoe
In comparison with Lake Baikal, Russia discussed yesterday, Lake Tahoe, located along the border between California and Nevada in the United States, is also a large freshwater lake. At a surface elevation of 1,897 m or 6,225 ft, Lake Tahoe is the largest alpine lake in North America. With a depth of  501 m or 1,645 ft, it's the second-deepest lake in the United States. The deepest lake in the United States is Crater Lake in Oregon at 593 m or 1,945 ft; and the deepest lake in the world is Lake Baikal in Russia at 1,642 m or 5,387 ft.

Lake Tahoe is ranked as the 26th by volume in the world at 151 cu km while Lake Baikal is the largest with a volume of 23,600 cu km. Lake Tahoe was formed about 2 million years ago. It is relatively young, compared to Lake Baikal's age at 25 million years.

Although Lake Tahoe is known for its great clarity, the clarity of the lake had been decreasing historically, with the rate of decrease slowing. Furthermore, the lake's clarity has increased from 2011 to 2013. We hope this trend will hold.

Postcard US-2193280 showing Lake Tahoe was received on April 25, 2013.
