Sergeant Floyd River Museum

The Sergeant Floyd River Museum & Welcome Center, a National Historic Landmark, is located in Sioux City, Iowa. The museum is housed inside the M.V. Sergeant Floyd, a retired U.S. Army Corps of Engineers towboat. Launched in 1932, the M.V. Sergeant Floyd served as a workhorse for the Missouri River Division of the Corps of Engineers, involved in river improvement work, moving men, equipment, and supplies, and setting navigation buoys. The museum is named in memory of Sergeant Charles Floyd, the only fatality of the Lewis and Clark Expedition. Floyd, described as a “man of much merit” by William Clark, died on August 20, 1804, near present-day Sioux City. Exhibits inside the museum feature rare photos, artifacts, and dioramas depicting the history of Missouri River transportation. Visitors can explore the restored third level of the Motor Vessel. The museum also features the largest exhibit of scale Missouri River steamboat and keelboat models. In addition to the museum, the facility also functions as a welcome center, providing information about the tri-state area. The museum is adjacent to Chris Larsen Park, the Lewis and Clark Interpretive Center, and a riverfront walking trail.
