摘要：	On March 19, the St. Paul Engineer District reported the opening of the 2021 navigation season when the mv. R. Clayton McWhorter pushed 12 barges through Lock and Dam .3, near Welch, Minn., at around 1:45. A number of news outlets picked up and repeated the announcement. But it won't be a complete opening until work is completed at Lock and Dam 25 at Winfield, Mo. Traditionally, the navigation season is considered to open with the first tow originating from St. Louis or below and passing through all of the Upper Mississippi locks and Lake Pepin to reach the Twin Cities. However, the R. Clayton McWhorter originated from the Quad Cities. Nevertheless, the district reported that the tow "marks the unofficial start of the 2021 navigation season. "Located between the Minnesota cities oi Red Wing and Wabasha, Lake Pepin is the last major barrier for vessels reaching the head of the navigation channel in St. Paul, Minn. The lake (really a wide spot on the river) is the last part of the river where ice breaks up, because the river is wider and subsequently the current is slower there than it is at other reaches of the river. If a tow can make it through Lake Pepin, it can make it all the way to St. Paul.
