How Deep Is Lake Tahoe?

Lake Tahoe has a maximum depth of about 1,645 feet (501 meters), making it the second deepest lake in the United States after Crater Lake in Oregon. Its average depth is approximately 1,000 feet (305 meters), with the deepest points located near Rubicon Point and Crystal Bay.

The lake's great depth is due to its unique geological history, including faulting and glacial erosion. This depth contributes to its stunning blue color and supports cold-water fish species such as Lahontan Cutthroat Trout and Mackinaw Trout.

Lake Tahoe covers about 191 square miles and sits at an elevation of roughly 6,225 feet above sea level, making it one of the largest and highest alpine lakes in North America. The lake's clarity allows visibility up to 70 feet underwater, a rarity linked to its depth and clean environment.
