About
The St. Paul District’s navigation program provides a safe, reliable, cost-effective and environmentally sustainable waterborne transportation system on the Upper Mississippi River
for the movement of commercial goods and national security needs. To do this, the district maintains a 9-foot navigation channel and 13 locks and dams from Minneapolis to Guttenberg, Iowa.
Lock and Dam No. 3 lies on the Upper Mississippi River six miles upstream of Red Wing, Minn. The project includes a lock, dam with moveable gates and a spot dike system to maintain the pool. The Corps of Engineers originally completed the facility in July 1938 as part of the 9-foot channel authorization. It serves as one of 29 locks and dams on the Upper Mississippi. In 1991, the Corps completed a major rehabilitation of the structure to provide service well into the future.
