摘要：	The mv. W. Red Harris, owned by Marquette Transportation, broke its way through the ice of Lake Pepin March 21 to become the first boat to kick off the unofficial start of the 2022 navigation season on the Upper Mississippi River. The W. Red Harris has passed the mv. Aubrey B. Harwell. The tow pushed by the mv. W Red Harris originated from St. Louis, Mo. The boat was pushing nine barges en route to St. Paul, Minn. It passed through Lock and Dam 3, near Welch, Minn., at about 2 p.m. March 21. The tow is the first vessel of the 2022 navigation season to pass through Lake Pepin, the last major barrier for vessels reach- ing the head of the navigation channel in St. Paul. The lake, located between the Minnesota cities of Red Wing and Wabasha, is the last part of the river to break up because the river is wider, and subsequently the current is slower there than it is in other parts of the river. If a tow can make it through Lake Pepin, it can make it all the way to St. Paul. The Army Corps of Engineers measures ice thickness on Lake Pepin throughout the spring to report to towing companies about the impending ice-out.
