Humans have been struggling to confine it for more than a century. The costs seem to be higher than the benefits.

It was also hugely variable in size and shape. Below Yankton, South Dakota, where a narrow valley gave way to a flat expanse five to 18 miles wide, the Missouri and its various secondary channels, sandbars and the like "had a width of 1,000 to 10,000 feet during normal flow periods," historian Robert Kelley Schneiders wrote in 1999. During a flood, which usually came in April when snow melted in the Great Plains, or in June when it melted in the Rocky Mountains, the river could become a "foaming, misdirected monster" that covered the entire valley, sometimes with ice as well as water.
