The lake is 1,943 feet (592 m) deep at its deepest point, which makes it the deepest lake in the United States, the second deepest in North America and the ninth deepest in the world.
It is the deepest lake in the United States with a depth of 594 m (1,949 ft). Crater Lake is fed solely by falling rain and snow, with no inflow or outflow at the surface, and hence is one of the clearest lakes in the world.
