The Flood Of 1920-Palm Sunday (March 28th, 1920) Manistique, MI-The most catastrophic event to occur in Manistique other than the fire of 1883 was the flood of 1920. Floodwaters began pouring over the flume walls in the early morning of Palm Sunday, March 28, 1920. The immediate cause of the flood was an ice jam on the Driggs River that backed the river up. When the jam broke, the water and logs in the river rushed into the Manistique River. Since the winter had an exceptional snowfall along with warmer than normal temperatures and several days of rain, the rivers draining into the Manistique River were already swollen. With the torrent of water, a west bank wall broke, causing water to rush over the flume walls and into the west side of Manistique all the way down Deer Street and Chippewa Avenue.
