Pepie
Also known as Lake Pepin Monster, Lake Monster of the Mississippi River
A serpent-like creature said to lurk in Lake Pepin, a broad stretch of the Mississippi River, reported in newspapers since the 1860s.
Pepie is the friendly nickname of a reputed lake monster in Lake Pepin, the widest natural stretch of the Mississippi River, where the river spreads into a lake about 22 miles long and up to 2 miles wide between Minnesota and Wisconsin. The lake formed where the delta of the Chippewa River partly dammed the Mississippi, and its bluffs, river towns and wide, choppy water make it a natural setting for a “Loch Ness of the Midwest.”
The legend has several layers. Local boosters often say that Dakota people who lived along the river preferred sturdy dugout canoes on Lake Pepin because large creatures could damage bark canoes – a story repeated in tourism materials, though it is hard to trace to documented Dakota sources. Newspapers of the 1860s and 1870s carried reports of large unknown animals in the lake, including an 1871 account in the Wabasha County Sentinel of a “marine monster” somewhere between an elephant and a rhinoceros in size.
Modern interest grew in 2008, when Larry Nielson, owner of the Lake City paddle-wheeler Pearl of the Lake, offered a $50,000 reward for a convincing photograph or a bit of fin or skin that a University of Minnesota biologist could confirm. Nielson says he has seen things on the lake he cannot explain. Folklorists Chad Lewis and Noah Voss collected historical and modern reports in their book Pepie: The Lake Monster of the Mississippi River, and the creature has since featured in cable-TV monster series.
Today Pepie is mostly a cheerful mascot for Lake City, Minnesota – the self-styled birthplace of water skiing – and the Wisconsin river towns across the water. Shops sell Pepie T-shirts and mugs, and the reward has never been claimed.

Where and when it’s seen
The open water of Lake Pepin between Lake City and Frontenac, Minnesota, and Pepin, Stockholm and Maiden Rock, Wisconsin, mostly seen from boats on calm summer days.
Notable sightings
- August 1867Rafters report an unknown creature Lake Pepin
The first known newspaper account came from river rafters from St. Louis, who said they had seen a large, unidentified animal in the water.
- April 28, 1871A “marine monster” in the Sentinel Lake Pepin, near Wabasha, Minnesota
The Wabasha County Sentinel described a creature between the size of an elephant and a rhinoceros moving with great speed. The Minnesota Historical Society’s almanac lists the date as a lake-monster sighting.
- June 2008The $50,000 Pepie reward Lake City, Minnesota
Paddle-wheeler owner Larry Nielson and Lake City promoters announced a $50,000 reward for indisputable proof of the creature. The offer drew national press attention, but no claim has succeeded.
What could explain it?
- Lake sturgeon and large paddlefish and catfish live in this stretch of the Mississippi and can break the surface in surprising ways.
- Floating logs and dead trees snagged on sandbars, boat wakes and swimming animals such as otters or deer are frequent sources of “monster” sightings on big rivers.
- Nineteenth-century newspapers often printed sensational or tongue-in-cheek monster stories, and one later report was attributed to a huge eel that was caught.
- The modern legend is openly promoted for tourism, which encourages reports without independent evidence.
Legend, culture and tourism
Lake City embraces Pepie as a mascot, with souvenirs, a dedicated tourism page and talk of a Pepie festival. Chad Lewis and Noah Voss’s book on the creature and TV appearances on Monsters and Mysteries in America spread the story nationally. Lake Pepin also figures in Laura Ingalls Wilder’s Little House books, as Pepin, Wisconsin, is her birthplace.
Places to visit
Lake City’s tourism bureau tells the Pepie story and invites visitors to look for the creature from the lakefront.
