The U.S. Army Corps of Engineers St. Paul District, has released a very interesting video named ‘The Dredger Goetz: Keeping the Upper Mississippi River Navigable’.
The St. Paul District maintains a 9-foot navigation channel by dredging around 1 million cubic yards of river sand each year from the Minnesota, Black, St. Croix and Mississippi rivers. This essential work supports commercial shipping, national security and the environment, said USACE.
