A prominent geographical feature straddling the border between California and Nevada, a large freshwater lake is readily identifiable on maps of California. Its location is in the Sierra Nevada mountain range, and its significant size and distinctive shape make it a landmark often used for orientation and reference.
The lake serves as a major recreational destination, contributing significantly to the economies of both states. Its presence influences regional climate patterns and provides a vital water source. Historically, the area surrounding it was inhabited by Washoe Native Americans, who held the lake sacred.
