A maximum depth of 1,645 feet in Crystal Bay makes Tahoe the second deepest lake in the USA, third deepest in North America and 11th deepest in the world. The elevation of Carson City, Nevada is 85 feet higher than the deepest part of Lake Tahoe. If the Willis (formerly Sears) Tower, the tallest building in North America, were dropped into Lake Tahoe at its deepest point, the top would still be submerged by 195 feet of water. The average depth is about 1,000 feet.
