History
The present site of Devils Lake was, historically, a territory of the Dakota people. However, the Sisseton, Wahpeton, and Cut-Head bands of the Dakotas were relocated to the Spirit Lake Reservation as a result of the 1867 treaty between the United States and the Dakota that established a reservation for those who had not been forcibly relocated to Crow Creek Reservation in what is now South Dakota. The name "Devils Lake" is a calque of the Dakota phrase mni wak’áŋ (literally translating to spirit water), which is also reflected in the names of the Spirit Lake Tribe and the nearby town of Minnewaukan.

The Dakota called the lake mni wak’áŋ, which separately translates as mni (water) and wak’áŋ (literally meaning "pure source" but often translated as "spirit" or "sacred"). The European-American settlers misconstrued this name to mean "Bad Spirit Lake" or "Devils Lake." The "bad" referred to the high salinity of the lake, making it unfit to drink, and "spirit" referenced the mirages often seen across the water. The Christian concept of the devil was not present in the Dakota philosophy and religious practices.
The Hidatsa name for the lake is mirixubaash ( meaning "sacred water").
The first post office was founded November 15, 1882, and was originally named Creelsburg.
