Floods in the United States: 1901–2000

Floods in the United States are generally caused by excessive rainfall, excessive snowmelt, and dam failure. Below is a list of flood events that were of significant impact to the country, 1901 through 2000, inclusive.

On June 6, 1903, after heavy rain, the Pacolet River destroyed or heavily damaged six large cotton mills, their associated dams, and 70 houses in the mill villages of Converse, Clifton, and Pacolet, South Carolina. Approximately 100 people were killed.

The third deadliest flash flood in US history, the normally placid Willow Creek burst its banks during an intense rain and hail storm. The city of Heppner, at the foothills of the Blue Mountains in eastern Oregon, was almost completely destroyed. 220 of Heppner's 1,400 residents died in the flood.

flooding was more significant along the Grand, Saginaw, Kalamazoo, and River Raisin river basins than the St. Joseph and Huron River basins. In Lansing, it was the worst flood in the previous 135 years of its history. Many dams were either undermined or swept away. Kalamazoo saw two square miles of flooding during this event.

It was also considered the most destructive flood in Grand Rapids history. The Grand River went above bankfull on the night of March 24, rising slowly for the next four days. It broke the previous high-water mark by over 60 cm (2.0 ft), and was considered a once in 100 year flood. Over one-half of the population on the west side of the river was inundated. On the east bank of the river, numerous factories went underwater. There was one casualty. Damages totaled US$1.8 million (1904 dollars).

A tropical storm in late 1906 reported highest ever rainfalls in a southeast to northwest direction from Monterey to Ione in the Sierra Nevada foothills. An area of 300,000 acres (1,200 km2) was flooded in the Sacramento Valley.
