Sierra Sun file photoThe Lake Tahoe Dam at Tahoe City controls the lake's only natural outlet.

The dam at Lake Tahoe, where the Truckee River begins, holds back more than 238 billion gallons of water just the top six feet of the lake.Six feet may not sound like much in a lake that reaches 1,645 feet deep, but spread out over 191 square miles, the gallons add up.Constructed from 1909 to 1913, the dam is 18 feet high and 109 feet long, built from 1,000 cubic yards of concrete.Water flows out of 17 five-by-four-foot gates to supply the Reno-Sparks area.Now operated by the federal government for water supply, earlier dams were built at Tahoes outlet to create an aqueduct to San Francisco, log fluming and electricity generation.
