NASHVILLE, Tenn. (RFD NEWS) — U.S. inland waterways continue to play a central role in keeping American agriculture competitive, moving bulk commodities efficiently while supporting jobs, exports, and the delivery of farm inputs. New federal research shows the system’s economic value has grown even as aging infrastructure raises concerns about long-term reliability.
Updated analysis finds inland waterways generate roughly $30 billion in annual economic output and support more than 200,000 jobs nationwide. Agricultural exports account for a large share of that impact, with grain shipments alone supporting about 122,000 jobs, $8 billion in labor income, and $18 billion in GDP each year. Soybeans and corn dominate export volumes, followed by wheat, rice, and sorghum.
For producers, waterways help keep transportation costs low for both outbound grain and inbound fertilizer. Many states along major river systems rely on barge traffic to meet most or all of their nitrogen fertilizer demand, helping stabilize input availability and pricing.
Regionally, the Mississippi River and Columbia–Snake River systems anchor export flows across the Midwest, Plains, Pacific Northwest, and Delta, linking inland production to global markets.
Looking ahead, analysts warn that without investment in lock expansion, dredging, and rehabilitation, disruptions could raise costs, slow exports, and weaken U.S. competitiveness against countries improving their own transport networks.
