Missouri River Shipping: Billions Spent, Little Return
Despite significant investments in improving the navigability of the Missouri River, grain shipments have dwindled to almost negligible levels. Observations from a recent trip highlight the inefficiencies of transporting grain from South Dakota and Minnesota to the Twin Cities before shipping it south. This raises questions about the effectiveness of current spending on port improvements and the future of river transport in the region.
Historical Context of River Transport
The history of river transport in the United States dates back over two centuries, when steamboats on navigable rivers spurred rapid economic growth. New Orleans emerged as a natural seaport, allowing smaller steamboats to navigate the Mississippi, Ohio, and Missouri rivers. This cheap transportation facilitated the movement of agricultural and industrial goods, while also bringing essential supplies to burgeoning communities.
As railroads became a viable alternative for transporting goods far from navigable rivers, the reliance on steamboats diminished. However, diesel-powered towboats eventually replaced the traditional sternwheelers, leading to a resurgence in low-cost water transport. In the 1930s, Congress initiated funding for a series of locks and dams on the Upper Mississippi River, which were completed by 1940. Similar projects were undertaken on the Ohio and Tennessee rivers, as well as the Missouri, which was seen as a logical extension of these efforts.
Despite the billions spent on making the Missouri River navigable, its unpredictable nature has posed significant challenges. The river’s steep elevation changes and shifting channels have made it difficult to maintain a reliable shipping route. While some improvements were made with the construction of six large dams, flooding events have continued to disrupt navigation, leading to costly dredging efforts.
Current Challenges and Future Implications
Today, the Missouri River’s topography remains a significant barrier to efficient shipping. The river’s steep gradient and swift current create challenges for towboats, which struggle to navigate the narrow, winding channels. While the river can accommodate barges, the volume of cargo transported is minimal compared to the Mississippi River. Recent statistics show that Sioux City, Iowa, only managed to load about 160 barges for transport to St. Louis, while the Twin Cities handled between 3,300 and over 5,000 in recent years.
This disparity raises concerns about the return on investment for the billions spent on improving the Missouri River. Critics argue that Congress often funds too many projects without fully considering their long-term viability. The current situation mirrors the challenges faced by U.S. ports, where deepening efforts to accommodate larger vessels often result in underutilized capacity.

As the debate over infrastructure spending continues, the lessons learned from the Missouri River’s struggles may inform future decisions regarding port improvements and the allocation of federal resources. The need for a balanced approach that considers both economic viability and environmental factors will be crucial in shaping the future of river transport in the United States.
