EXTREMES OUTSIDE PERIOD OF RECORD - Maximum stage in Minot occurred in 1881, and was at least 3 ft higher than 1904 peak of 21.9 ft (site and datum then in use), according to April 20, 1904, issue of Minot Daily Optic. Review of weather records and additional historic flood information suggest that the 1881 peak may have actually occurred in 1882.
