The Souris River broke the 130-year-old record high and kept going because of the heavy rains upstream and dam releases water to the rivers.
By Friday evening, the brownish river water had risen to more than four feet above historic 1969 flooding and topped the 1881 record by two feet.
North Dakota Gov. Jack Dalrymple says the Souris River is flowing over most levees in Minot.
