The Motor Vessel Roberta Tabor, a towboat owned by American River Transportation Company in St. Louis, locks through the Corps’ Lock and Dam 2 in Hastings, Minn., on Aril 8 in route to St. Paul, Minn. The motor vessel is pushing 12 barges. Lake Pepin 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 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.
