The largest natural body of water in the state, Devils Lake sits at an elevation of 443.24 metres above sea level in north-eastern North Dakota. The lake is known for its variations in lake level, ranging from a shallow to a depth of 18 metres deep during periods of excessive precipitation.
Devils Lake is a known recreation lake, attracting both local and international tourists. It is home to the Grahams Island State Park and Sullys Hill National Game Preserve, while the Spirit Lake Reservation sits on the southern shores of the lake.
Most people come for its fantastic fishing, especially its perch. There are boat ramps to accommodate anglers, though other recreational activities are also enjoyed here, including camping, picnicking and boating. In the winter, the lake is open for ice fishing.
