Second Sunday Talks: Shifting Borders
Shifting Borders: The Battle for Carter Lake & Lake Manawa

What happens when a river decides to change course?
For Iowa and Nebraska, the answer was decades of legal battles, disputed land claims, and a border unlike any other in the nation.
Join us this August as historian Troy Stolp explores the fascinating story of Carter Lake and Lake Manawa, two bodies of water created when the Missouri River dramatically altered its course in the late nineteenth century. What began as natural disasters quickly became a complex legal puzzle as the shifting river changed the very boundary between Iowa and Nebraska.
Today, Carter Lake remains one of the most unique communities in America. Although surrounded by Omaha, it is officially part of Iowa. Meanwhile, Lake Manawa emerged as one of the region’s most popular recreational destinations while attracting competing claims from both states.
Through historical research, maps, photographs, and compelling stories, Troy will unravel how floods, geography, politics, and the courts combined to create one of the most unusual border disputes in American history.
If you’ve ever wondered why Carter Lake belongs to Iowa, despite appearing to be part of Omaha, this presentation is for you.
