The U.S. Army Corps of Engineers, St. Paul District, released its 2021 navigation statistics for the Upper Mississippi River today, Jan. 10.

During the 2021 season, Corps staff supported 2,269 commercial navigation lockages at Lock and Dam 7, near La Crescent, Minnesota, which was slightly above the 10-year average of 2,225 lockages. The 2021 lockages supported 10,079,565 tons, or approximately 6,500 barges of commodities shipped by the navigation industry. During the 2020 season, Corps staff supported 2,617 commercial lockages and the movement of 12,448,417 tons of commodities.

In addition to the commercial lockages, Corps staff locked 3,574 recreation vessels during 1,558 lockages. To minimize lockages, the Corps tries to include multiple recreation vessels during a single lockage. There were an additional 27 lockages from various government agencies including the Corps.                                                                                                                                          

The 2021 navigation season unofficially ended Nov. 28, 2021, after the Motor Vessel Jonathon Erickson departed St. Paul, Minnesota. The 2021 navigation season started March 19, 2021, when the Motor Vessel R. Clayton McWhorter locked through Lock and Dam 2, near Hastings, Minnesota, en route to St. Paul.

Navigation statistics fluctuate from year to year, depending on the weather, river flows and the length of the navigation season. The St. Paul District maintains a 9-foot navigation channel from Minneapolis to Guttenberg, Iowa. Keeping this system open is vital to the nation’s economy.
