Lewis and Clark State Park lies on the shores of Blue Lake, an "oxbow" formed by the meanderings of the picturesque Missouri River many years ago.

The park is named for Meriwether Lewis, secretary to President Thomas Jefferson, and Captain William Clark, United States Army, who were commissioned by President Jefferson in 1804 to head an expedition into the northwest to explore the vast territory purchased from France. With 26 men and supplies, Lewis and Clark led their expedition up the Missouri River from St. Louis by keelboat.

On August 10, 1804, the expedition arrived at the site where Lewis and Clark State Park now lies. They spent some time there exploring the region and making observations on the geographical conditions, plants and animals in the area. Today, thousands of people visit the park every year for outdoor recreation and to learn a little bit more about the Lewis and Clark expedition. The park has been designated as part of the Lewis and Clark National Historic Trail by the National Park Service.
