Which lake is the deepest in the United States?

• A. Lake Tahoe
• B. Great Salt Lake
• C. Loch Ness
• D. Crater Lake

Answer: (D)

Measuring how far the bottom sits below the surface reveals why Crater Lake is the deepest lake in the United States. Crater Lake formed in a volcanic caldera that collapsed, creating a deep, steep-walled basin. When it filled with rain and snowmelt, there was little erosion to shorten the depth, so the bottom lies far below the surface. Its maximum depth is around 1,900 feet, which is greater than other well-known US lakes—the water in Lake Tahoe, for example, reaches about 1,645 feet, while the Great Salt Lake’s depth is shallow in comparison, averaging around 30 feet. Loch Ness is deep, but it’s in Scotland, not the United States. So Crater Lake stands as the deepest in the country.
