The deepest lake in the United States is Crater Lake in southern Oregon. Measurements at the deepest part of the lake indicate that it reaches a total depth of 1,949 feet. Not only is Crater Lake the deepest body of water in the US but it also holds the distinction of being the ninth deepest in the entire world. Coming in ahead of Crater Lake on the list of the deepest lakes on Earth are Great Slave Lake (2,015 feet), Issyk Kul (2,192 feet), Nyasa (2,316 feet), O'Higgins-San Martin (2,742 feet), Vostok (2,950 feet), the Caspian Sea (3,363 feet), Tanganyika (4,823 feet), and the world’s deepest lake, Baikal, located in Siberia, Russia which reaches depths of 5,387 feet.
Also known as a Caldera, Crater Lake gets its name because it is a volcanic crater which was formed about 7,700 years ago when Mount Mazama erupted, emptying a magma chamber. The peak of the mountainous now-dormant volcano is thought to have measured 12,000 feet before it crumbled following the major eruption. The layer of rock sitting atop this now empty chamber then collapsed thus creating a crater which measures over six miles across. The water filling the lake is the result of years and years of extensive rain and precipitation which has eventually filled up the crater.
Crater Lake is characterized by the fact that this particular body of water has no streams or rivers running in or out of it. Because of this, the water level in Crater Lake remains fairly stable with the amount of water flowing out of it, due to environmental factors such as evaporation, is balanced by the amount going into it in the form of precipitation.
Crater Lake National Park spans 286.29 square miles in Klamath County, Oregon and is well known as a tourist destination and popular draw for visitors who travel there in search of its awe-inspiring natural scenery and deep blue water. According to the US’s Park Service Crater Lake, which was established back in 1902, contains some of the cleanest lake water in the world. The park includes two visitor centers, the Rim Visitor Center and the Steel Visitor Center. Also, among its most popular exhibits are the Crater Lake Lodge and the Sinnott Memorial Overlook.
Crater Lake Natural Park is also a popular spot for visitors and locals alike to take part in various recreational activities such as camping, fishing, boating, and hiking. Interestingly, although Crater Lake is thought to contain no indigenous fish species it was artificially stocked with fish including salmon and trout from 1888 until 1941.
The second deepest lake in the US is Lake Tahoe located in the Sierra Nevada mountain range where it sits on the state line separating the western states of Nevada and California. With a depth of 1,645 feet, this freshwater lake measures approximately twelve miles wide and twenty-two miles long. Like Crater Lake, Lake Tahoe is a major tourist destination and the site of numerous recreational activities all year round.
