Last day at Upper St. Anthony Falls lock
The end of an era was witnessed at 11:17 p.m., June 9, 2015, when the last boat, a recreation craft, locked through the Upper St. Anthony Falls lock. The Water Resources Reform and Development Act of 2014, signed June 10, 2014, directed the Corps of Engineers to close Upper St. Anthony Falls Lock to navigation within one year of the act being signed into law. In 1937, Congress authorized the Minneapolis Upper Harbor Project which extended the Upper Mississippi River 9-Foot Navigation Project an additional 4.6 miles by constructing two locks to lift vessels over St. Anthony Falls. The Upper St. Anthony Falls Lock was completed in 1963.
