Devils Lake is a lake in the U.S. state of North Dakota. It is the largest natural body of water and the second-largest body of water in North Dakota after the artificially created Lake Sakakawea. In 2011, it reached an unofficial historical high elevation of 1454.30 feet (443m). The lake can reach 1458.0 before naturally flowing into the Sheyenne River via the Tolna Coulee. The city of Devils Lake, North Dakota, takes its name from the lake and the Spirit Lake Reservation is located on its southern shores. The name "Devils Lake" is an approximate translation of its Lakota name, Ble Waka Sica ("blay wah-kahn shee-chah"; literally: "Lake of the Spirits").
