Event narrative (NOAA)
Flash flooding hit all the creeks and drainage areas hard that begin near the Interstate 90 area in Winona County. Garvin Brook and other creeks that flow into Stockton became terrain-changing flowages that washed out numerous roads, created massive mudslides, took out bridges, damaged railroad tracks, and washed away some homes.||Most homes in Stockton had severe water damage as flood waters roared through town.||Erosion problems were also noted south of Interstate 90 in the Hart area. Many roads, including Highway 43, were closed for several days.
