Lock and Dam No. 1
Lock and Dam No. 1 is one of the steps in the "stairway of water" on the Mississippi River that makes possible the travel of barges from St. Anthony to the Gulf of Mexico. Commercial barges carried over 15 million tons of commodities through the Lock. Among the commodities are: coal, burner oils, grain, and aggregate products.
Lock and Dam No. 1 provides for both commercial and recreational uses. Along with the commercial barges are recreational crafts ranging from canoes and rafts to houseboats and sleek powerboats.
Activities: There is a 30-minute tour called the Visitor Promenade offering a bird's-eye view of the locking procedure and other topics ranging from barge traffic in the transportation network to the Corps 9-foot channel project.
Hours: Please call for more information.
