The American River does not flow directly from Lake Tahoe to the Sacramento River, but this map shows the south fork of the “Rio de los Americanos” with a direct path from what was then known as “Mountain Lake” into the “Rio Sacramento” past the town of “Nueva Helvetia”. The Spanish names reflect that California was controlled by Mexico at the time this map was created in the early 1840s. John Charles Fremont’s expedition across the western portion of North America included the region of the American River which would later become the center of the Gold Rush.
The naming of Lake Tahoe took many twists and turns that are reflected on early maps of California and the western states. In Fremont’s early surveys, the lake was simply named Mountain Lake. Later, Charles Preuss, a cartographer working with Fremont, drew the lake as Lake Bonpland in homage to Aimé Bonpland, a French botanist and explorer of South America.In 1870, the lake was officially named “Lake Bigler” in honor of John Bigler, governor of California from 1852 to 1856. However, Bigler was a strong secessionist during the Civil War, and having his name on the lake was unpopular. The official name remained on maps published by the State of California until the California Legislature formally changed it to Lake Tahoe in 1945. Here we have an 1849 map that is unique in referring to the lake as “Fremonts L.” [Fremont’s Lake]. This 1884 map of Central California is particularly interesting in that shows Lake Bigler and Lake Tahoe as being interchangeable names referring to the same body of water.
And finally we see the name Lake Tahoe returning to its Washo Native American beginnings meaning “big water” in this 1900 map issued by the California-Paris Exposition Commission of 1900.
