One of the largest lakes in the state, Lake Poinsett was named after Joel Poinsett who served as U.S. Secretary of War. He was instrumental in promoting the expedition of Joseph Nicollet and John Fremont who first explored the region in 1838. The party camped on the north side of Lake Poinsett. Today, the lakeshore still provides excellent camping opportunities, as well as many other recreational activities.

The Lake Poinsett Visitor Center and Museum is a fascinating place to learn about the history of the area. During the summer, neighbor Harlan Olson's artifacts are on display. The exhibits will take you back in time from prehistoric days to the late 1990s.
