Crater Lake is a caldera lake located in south-central Oregon. It is 8 by 9.7 kilometers (5 by 6 miles) across, with a caldera rim ranging in elevation from 2,100 to 2,400 meters. It is the deepest lake in the United States and the second deepest in North America.
At its deepest point it is about 1,949 feet. It has a surface area of 53 square kilometers. The lake is isolated from surrounding streams and rivers so there is no inlet or outlet to it. It is filled with rain and melted snow from the caldera basin.
