Missouri experienced multiple major floods during the 20th century. These floods were caused by heavy rainfall, snowmelt, and the overflowing of the Mississippi and Missouri Rivers. Cities, towns, and farmland were frequently affected, creating damage to homes, roads, and bridges.
The 1915 flood hit the Missouri River Valley with severe force. Water levels rose quickly, washing away riverbanks and inundating towns along the river. Many families were forced to evacuate, and livestock drowned in low-lying areas. Emergency services struggled to respond because communication systems were limited at the time.
In 1927, Missouri was affected by the larger Mississippi River flood. Levees broke in several areas, causing widespread destruction. Railroads were submerged, cutting off transportation and supply routes. Farmers lost entire crops, which caused food shortages and economic strain.
Flood control measures began after these early disasters. Levees were reinforced, and dams were constructed to manage river flow. Despite these improvements, the 1951 Missouri River flood caused extensive damage. Kansas City and surrounding communities faced rising waters, forcing evacuations and emergency sandbagging operations.

The 1973 flood was another major event in Missouri. Rainfall over several days caused tributaries of the Missouri River to overflow. Cities like Jefferson City and Columbia saw streets under several feet of water. Bridges were closed, schools were canceled, and emergency shelters were set up in gymnasiums and community centers.
In 1993, Missouri faced one of the worst floods in its history. Heavy rains over the Midwest caused both the Mississippi and Missouri Rivers to overflow simultaneously. Entire counties were declared disaster areas. Roads were washed out, towns were isolated, and thousands of homes were damaged. The flood affected agriculture, with millions of acres of crops destroyed.
Flooding often prompted state and federal responses. The Army Corps of Engineers worked to reinforce levees, clear debris, and build floodways. Local governments coordinated evacuations and provided temporary shelters. Community volunteers contributed by filling sandbags, rescuing stranded residents, and distributing supplies.
Missouri’s geography made it especially vulnerable. The combination of large rivers, rolling plains, and low-lying floodplains allowed water to spread quickly during heavy rainfall. Towns built near riverbanks were particularly at risk, and bridges and roads were often damaged or washed away.
Throughout the 20th century, flooding shaped the development of Missouri’s infrastructure. Levees, dams, and floodwalls were strengthened after major events. Emergency response plans were updated, and new technologies for monitoring river levels were implemented. Flood insurance programs were introduced to help residents recover financially.
Floods in Missouri also affected daily life. Families had to move possessions to higher ground, schools and businesses were closed, and travel became difficult. Livelihoods, especially farming, were disrupted for weeks or months. Local newspapers regularly reported on water levels, road closures, and evacuation orders.
