The episode as NWS DVN wrote it up.
The runoff from very heavy rains that fell in southern and eastern Minnesota and western Wisconsin on September 22-23, 2010 flowed down the Mississippi River during late September and into the first half of October. Minor to moderate flooding occurred from Dubuque, Iowa southward to Gregory Landing, Missouri. Crests along this portion of the river were generally 2 to 3 feet above flood stage. At Dubuque the river rose above flood stage on September 29 and fell below flood stage on October 11. At Burlington the river rose above flood stage on October 2 and fell below flood stage on October 16. Interesting to note that this was only the 3rd or 4th time (depending on location) since 1862 that the Mississippi River has flooded during the fall season.
