An aerial view shows a person walks with a dog on an earthen dike near the Red River south of Fargo, North Dakota March 29, 2009. A dike holding back the swollen Red River failed early on Sunday and swamped a school in Fargo, North Dakota, but a backup dike contained the spill as cold weather favored flood fighting and evacuation efforts.
