Devils Lake Serpent
Also known as Devils Lake Sea Monster, Devils Lake Monster (North Dakota)
A horned, alligator-jawed serpent said to rise from Devils Lake, North Dakota, rooted in Dakota tradition and promoted by 1890s–1910s newspapers.
Devils Lake is North Dakota’s largest natural lake, a broad prairie lake with no natural outlet that has swollen dramatically in recent decades. Its Dakota name, Mni Wakan – rendered by settlers as Minnewaukan – is usually translated as “spirit water” or “mysterious water,” and the lake has long been associated with a great serpent.
Older stories from the Dakota and other peoples of the region tell of a monster that devoured those who came too close, including one in which a water serpent swallowed an entire Dakota war party after a battle with the Ojibwe. These traditions belong to the Spirit Lake Dakota and neighboring nations and carry meanings that go far beyond a “monster sighting.”
Settler newspapers gave the serpent a second life. After the railroad reached Devils Lake in 1883, local boosters revived monster tales to draw tourists. In 1894 newspapers – including the New York Sun and the Grand Forks Herald – reported that picnickers from Larimore had seen an amphibious serpent, describing alligator-like jaws, red eyes, a slimy green body and an 80-foot tail that liked to appear around sunset in August. In 1904 three women from Leeds reported a sighting at the lake’s Chautauqua grounds, a story reprinted nationally, and the Grand Forks Herald logged further sightings and “talk of expeditions” between 1906 and 1915.
Descriptions shifted wildly – in July 1908 tourists described a black, twelve-foot creature with sharp horns on both sides of its head that shot half its body out of the water. By the 1930s the Federal Writers’ Project guide to North Dakota offered a natural explanation: on certain days, vapor over the lake magnifies birds on the surface until they look like ships or monsters. The serpent has never quite gone away, resurfacing in features from a 1941 Minneapolis newspaper to modern Halloween coverage.

Notable sightings
- 1894The Larimore picnickers Devils Lake, North Dakota

- February 9, 1941“Sea Monster” revisited <em>Minneapolis Star Journal</em>
A feature article revived the legend of the Devils Lake sea monster for a new generation of readers.
What could explain it?
- Town boosters openly used the monster to promote tourism after the railroad arrived in 1883, and many early reports read like promotional tall tales.
- The Federal Writers’ Project noted that atmospheric vapor and mirage over the lake can make birds on the water look enormously magnified.
- Pelicans, cormorants, swimming deer, large northern pike and floating debris can be misread on a wide, windy lake.
- Devils Lake is a shallow, closed-basin lake whose size has swung dramatically with climate; it could not have sustained a population of giant animals unnoticed.
Legend, culture and tourism
For the Spirit Lake Dakota Nation, whose reservation lies on the lake’s south shore, Mni Wakan is a place of deep spiritual significance. For the town of Devils Lake, the serpent is a colorful piece of frontier-era promotion and a recurring Halloween story, while the lake today is best known as a walleye and perch fishing destination.
Places to visit
A state park on an island in the lake, with campgrounds, boat ramps and broad views of the serpent’s waters.
