National Mississippi River Museum & Aquarium

The National Mississippi River Museum & Aquarium is owned and operated by the Dubuque County Historical Society, which also operates the Mathias Ham Historic Site. The River Museum  and Mathias Ham Historic Site together see over 200,000 visitors and manage outreach programs that serve over 50,000 more per year. Part aquarium, part museum, part science center, it is the mission of the institution to inspire stewardship by creating educational experiences where history and rivers come alive.
