A year ago this spring the city of Des Moines cut a new channel and mouth for the Raccoon River, causing it to change its course for a distance of about half a mile and to empty into the Des Moines River a little more than half that distance below its old mouth. The bulk of the excavated material was piled upon the south bank of the new channel to form a levee about fifteen feet high, sixty feet wide at the base, and twelve feet wide at the top, with a space of twelve feet intervening between the foot of the embankment and the river.
