Watch the brilliant blue water deepen at Crater Lake National Park, home to one of the cleanest and clearest lakes in the world. At 1,943 feet deep, Crater Lake is the deepest lake in America. Famous for its beautiful blue color, the lake’s water comes directly from snow or rain since there are no inlets from other water sources. This means that sediments or mineral deposits are not carried into the lake, helping it maintain its rich, mesmerizing color. | U.S. Department of the Interior
