That is a good question Joe. From all that I have read, while researching, the tracks were never out of service during flooding. The 1908 flood is considered the worst to hit the Shelby/ Water Valley area. In the pictures, the flood waters have advanced to almost the crossing of the Monon and the NYC Kankakee Belt. These residences are all south of the NYC tracks. When the river was dredged and straightened the area still was prone to flooding, but not like 1908.
