Flood — Trempealeau, WI

Jul 1, 2024

Heavy rainfall throughout June led to many locations along the Mississippi River in Western Wisconsin to enter flood stage which persisted into July. During the first week of July many points along the Mississippi River observed their maximum river stage in minor to moderate flooding. As relatively drier conditions took hold over the first half of July, river stages fell below flood stage into the middle of the month.
