Found this interesting,
"Heavy snow melt, moist soil, and North Dakota's peculiar geography combined over the weekend to turn the roads and fields around Fargo into a seemingly giant shallow ocean. Called overland flooding, it creates bizarrely apocalyptic scenes like this.
The Red River crested on Saturday night to the fourth highest level in history, sending water into the area around the cities of Fargo, North Dakota and its neighbor Moorhead, Minnesota. Because of the extreme flatness of this valley area, the water traveled mostly unimpeded at a slow, shallow rate across the empty plains."
