Mississippi River Between Missouri River and Minneapolis

The project consists of a 314-river-mile reach of 9-foot commercial navigation channel from Guttenberg, Iowa, downstream to Saverton, Missouri. It includes 14 locks and 11 dams (L/Ds) at 12 sites from Lock 11 to Lock 22. The navigable portions of this river and the locks and dams that allow waterway traffic to move from one pool to another are integral parts of a regional, national and international transportation network. Recreation facilities include 25 public recreation areas and the Visitor Center located at Locks & Dam 15. 

The system is significant for certain key exports and the Nation's balance of trade. More than 580 manufacturing facilities, terminals and docks ship and receive goods on the Upper Mississippi River Basin.  Annually, the regional project generates an estimated $3 billion of transportation cost savings compared to overland methods. FY18 recreation fee receipts and lease revenues were $1.5M; with regional economic impacts estimated at $100M with 3.5M visits.
