HISTORY

Commissioned in 1961, the Mississippi IV plied the Mississippi River for more than 30 years. Though it was the fourth Corps vessel to bear the name “Mississippi,” she was the first to employ diesel power, and this shift brought with it the designation “Motor Vessel”. Mississippi IV marked the advance of new technologies of the 1950s; steamboat manufacturers were turning to newer, more powerful diesel engines and producing fewer steamboat replacement parts, making it increasingly difficult to maintain steam-driven vessels. Although signaling the end of the steam era on the Mississippi River and the demise of the 19th-century technology that brought prosperity to the Mississippi Valley, Mississippi IV fulfilled the vision of the Corps for a workboat with a larger towing capacity and improved handling in rough waters, and maintained the needs of the MRC.

Mississippi IV served a dual role as both a workboat and an ambassador to citizens of the Lower Mississippi Valley. As a towboat, the vessel was a common sight along the Mississippi River as it delivered equipment and materials to Corps project sites generally administered by the Corps’ Memphis District. As a public ambassador, the vessel also hosted the public meetings of the Mississippi River Commission (MRC) during the Commission’s biannual inspection tours from Illinois to coastal Louisiana.

This dual role as Corps workhorse and MRC flagship required a vessel that combined functionality with public space. Mississippi IV utilized new technology and innovative design to meet the needs of the Corps, the MRC, and the general public.

On April 8, 1993, “Decommissioning-Commissioning Day,” the Corps retired Mississippi IV. The vessel was stored for more than a decade while plans developed for the Lower Mississippi River Museum to be built in Vicksburg, Mississippi. Mississippi IV was cosmetically restored in Morgan City, Louisiana, and moved by barge to Vicksburg in 2007. Now gently perched atop a concrete cradle near the waterfront, Mississippi IV continues her role as a public ambassador as a centerpiece of the Lower Mississippi River Museum which opened in 2012.

Flagships of the MRC

The vessels which have served as the Mississippi always pulled “double duty” serving both as a Corps work vessel and as the MRC’s river inspection vessel and public meeting venue. During the traditional high-water and low-water seasons each spring and summer, the members of the MRC conduct inspection trips and public meetings aboard the Mississippi at various locations along the length of the Mississippi River.

Mississippi River Commission

The Mississippi River Commission (MRC) was established on June 28, 1879 by an Act of Congress. Congress tasked the MRC with the mission to develop plans to improve the condition of the Mississippi River, foster navigation, promote commerce, and prevent destructive floods. Today, the MRC provides water resources engineering direction and policy advice to the Administration, Congress, and the Army in a drainage basin that covers 41 percent of the United States by overseeing the planning and reporting on the improvements on the Mississippi River.
