FLOOD control has been a problem of critical nature in the Mississippi Valley since settlement first began. De Soto's men saw the river in flood in 1543 when the areas east of the plains were covered with virgin forests. Great and small floods have inundated the bottomlands at frequent intervals since that time, and all were attended by losses to the country.
