248 Words1 Pages
Man Handling the River River navigation has changed dramatically since the Lewis and Clark expedition. With the rapid increase in population and commerce, a change in the river system became essential. It was realized that by narrowing and deepening the river, enormous areas of fertile, productive flood plain would become farmable. The U.S. Army Corp of Engineers was tasked to accomplish this. Over the past one hundred and fifty years they have tried to do this with levees, jetties, and locks and dams. “Along the upper Mississippi river between St. Louis, Missouri, and St. Paul, Minnesota are 29 locks and dams that divide the river into 29 flat pools designed to hold water back to maintain a nine-foot shipping channel”(Locks and Dams-Lesson).
