Weather History - March 27th

Local and Regional Events:

March 27th, 1993:

Rain and rapid snowmelt caused the Big Sioux and Vermillion Rivers to rise to 1 to 8 feet above flood stage from March 26th through March 31st, 1993. The worst flooding occurred in far southeast South Dakota, where large farmland areas were under water. The floodwaters closed at least four state highways in southeast South Dakota and blocked dozens of more minor roads in the east. Large chunks of ice on the Big Sioux led to many temporary ice jams. The ice jams took out fences and washed out roads. In some areas, the ice had to be pushed off the streets with tractors.
