What is the deepest lake in the United States?

The deepest lake in the U.S. is Oregon's Crater Lake. Crater Lake lies within the collapsed crater of an ancient volcano named Mount Mazama and is 1,932 feet deep (589 meters).

The clear water of Crater Lake has no steams to feed it and no streams as outlets - it was filled and is supported by precipitation and snow melt. Located in southern Oregon, the lake is the world's seventh deepest and contains 4.6 trillion gallons of water.
