The Lore
The Alkali Lake Monster has been reported in Walgren Lake (formerly Alkali Lake) near Hay Springs, Nebraska since the 1920s. The creature is described as 40 feet long, gray-brown, with a horn or bony protrusion on its head, spotted surfacing in a lake that is only 8 feet deep at its maximum. That paradox has never been explained. Witnesses include ranchers, fishermen, and a local newspaper editor who published accounts in the Hay Springs Herald. The Nebraska legislature considered making it a protected species, and a historical marker at the lake references the creature. In a state known for flat, open landscapes with no place for a large animal to hide, the sightings persist.
Notable Witnesses
- J.A. Johnson (Hay Springs Herald editor, 1920s)
- Multiple local ranchers
