CHARLESTON, W.Va. — Shaped by rugged mountains and winding rivers, West Virginia has endured some of the most catastrophic floods in American history.
Its five worst floods—measured by lives lost, destruction caused, and lasting impact—include the Buffalo Creek Disaster of 1972, where a coal slurry dam failure killed 125 people; the Election Day Floods of 1985, which claimed 38 lives and caused widespread damage; the Ohio River Flood of 1937, which inundated cities like Huntington and prompted major flood control projects; the 2016 Flash Floods, a thousand-year rain event that killed 23 and devastated multiple counties; and the 1943 Little Kanawha Flood, caused by a sudden deluge that also took 23 lives.
Altogether, these events underscore the state’s vulnerability to both natural and man-made disasters, highlighting the critical need for improved flood management and infrastructure resilience.
1. Buffalo Creek Flood, 1972
Death Toll: 125 | Homeless: ~4,000 | Cause: Coal slurry dam failure in Logan County
At dawn on February 26, 1972, the collapse of Pittston Coal Company’s dam No. 3 unleashed 132 million gallons of toxic coal slurry down Buffalo Creek Hollow near Logan. The surge obliterated 16 coal towns, killed 125 people, injured over 1,121, destroyed more than 507 houses, and displaced more than 4,000 residents.
The Buffalo Creek Flood remains West Virginia’s deadliest. Entire families perished, and survivors described the slurry wave of black sludge leaping between ridges like a tsunami. Environmental recovery spanned decades, with serious litigation and public outrage over the disaster’s scale and preventability.
2. Election Day Floods, 1985
Death Toll in West Virginia: 38 | Damage: ~ $700 million
In early November 1985, floods triggered by two Gulf-origin low-pressure systems brought record rainfall across West Virginia’s Potomac, Cheat, and Monongahela basins. At least 27 river gauges recorded 1-in-100‑year flood levels.
The Potomac River at Paw Paw crested 29 feet above flood stage, roads and bridges were washed out, and over 13,000 homes and businesses were damaged or destroyed. The Election Day Floods claimed 38 lives in the state and inflicted nearly $700 million in damage, making it the costliest flood in West Virginia history.
3. Ohio River Flood of 1937
Death Toll: Not specified statewide; massive property damage
The Ohio River Flood of 1937, among the Mississippi Valley’s worst floods, struck Huntington on January 28, 1937, when the river crested at 69.45 feet, nearly 19 feet above flood stage.
This Ohio River flood necessitated navigation by boat through submerged streets, evacuation of Wheeling Island and Parkersburg, and triggered the construction of the Huntington floodwall, which was completed in 1943. Although exact statewide fatalities in West Virginia are unclear, the human and economic costs were immense, prompting long-term flood control initiatives.
4. West Virginia Flood of 2016
Death Toll: 23 | Damage: ~$1.1 billion
On June 23–24, 2016, a catastrophic “thousand‑year” rainfall event soaked central and southern West Virginia with 8–10 inches of rain in under 12 hours.
Saturated soils and steep terrain funneled water into the Meadow, Cherry, Elk, and Greenbrier rivers, causing them to overflow into communities such as Clendenin, Richwood, Rainelle, and White Sulphur Springs.
The Elk River at Queens Shoals crested at more than 33 feet, breaking a 125-year record. The West Virginia Flood of 2016 claimed 23 lives, displaced more than 2,000 people, destroyed 1,500 homes and businesses, damaged 2,500 more, and resulted in approximately $50–53 million in road and bridge losses; the total estimated damages reached $1.1 billion.
5. Little Kanawha Flash Flood,1943
Death Toll: 23 | Location: Little Kanawha River Basin
On the night of August 4–5, 1943, intense thunderstorms dropped up to 15 inches of rain in just two hours over central West Virginia’s Little Kanawha River tributaries in Braxton, Calhoun, Gilmer, Ritchie, and Wirt counties.
The result: 23 fatalities, particularly in narrow hollows where water rose with lethal speed and swept away homes. Despite occurring in less-populated areas, the loss of life and suddenness make the Little Kanawha River Flash Flood one of the worst flash floods in West Virginia history.
Why these flooding events matter
The five deadliest floods in West Virginia's history are significant because they highlight the state’s profound vulnerability to both natural disasters and human negligence. These tragedies—characterized by sudden devastation, loss of life, and lasting economic impact—have significantly shaped public policy, emergency preparedness, and infrastructure development.
Each serves as a sobering reminder of the importance of strong environmental oversight, early warning systems, and resilient community planning in a region where heavy rainfall and narrow valleys can turn deadly in hours.
Fatalities & Shock
Only five floods killed more than 20 people in West Virginia's history. The Buffalo Creek flood tops the list by a wide margin (125 fatalities), followed by the 1985 Election Day floods (38 deaths), 2016 flash floods (23 deaths), and both the 1943 Little Kanawha and 2016 events, tying at 23 deaths. Those events starkly illustrate how quickly and devastatingly mountainous terrain and heavy rain can overwhelm communities.
Economic and Infrastructure Impact
The 1985 floods cost nearly $700 million, and the 2016 event exceeded $1 billion in total losses. The 1937 Ohio River flood led to the construction of major flood-control projects, including the Huntington floodwall. The Buffalo Creek disaster led to litigation, increased scrutiny of mining regulations, and long-term environmental consequences.
Causes: Natural vs. Man‑made
The Buffalo Creek Flood was a catastrophic man-made dam failure, the only event on this list directly tied to the collapse of industrial infrastructure. In contrast, the other floods were natural, caused by record-breaking rain totals, often linked to stalled fronts, tropical moisture, or hurricanes.
2016: A stalled frontal boundary brought repeated storms, creating “training rains” that dumped extreme rainfall into river basins.
1985 floods: A combination of wet soils, tropical-fed low systems, and a stalled front triggered extensive runoff.
1937 flood: A classic Ohio Valley event caused by prolonged snowmelt and upstream rainfall.
Community Flood Response & Lessons Learned
In the aftermath of the worst floods in West Virginia's history, communities have consistently shown resilience, unity, and determination to rebuild. From volunteer rescue efforts during the Buffalo Creek disaster to widespread fundraising and federal aid following the 2016 flash floods, each event has strengthened local awareness and emergency response capabilities.
These floods also prompted critical lessons, such as the need for stricter environmental regulations, improved dam safety, and investment in flood-resistant infrastructure. By learning from past tragedies, West Virginians continue to adapt and prepare for future flood risks with greater coordination and resolve.
Buffalo Creek (1972): Prompted regulatory scrutiny of coal slurry impoundments and dam safety rules, though legal settlements and federal cleanup efforts fell short of justice for families.
Election Day Floods (1985): Led to improved flood warnings, better preparedness, and new water management strategies in eastern West Virginia and neighboring Virginia communities.
2016 floods: Spurred recovery grants and federal disaster declarations, but also raised urgent questions about climate resilience for mountain towns in floodplains.
1937 Ohio River Flood: Led to infrastructure upgrades, including park evacuation plans and flood walls that still protect Huntington and Parkersburg.
1943 flash flood: Though less remembered, it underscored the peril of abrupt thunderstorms in rural valleys—a risk that remains.
Looking ahead at flood risk in West Virginia
West Virginia’s mountainous terrain, narrow valleys, and reliance on rivers make it especially vulnerable to sudden, catastrophic flooding. These five disasters demonstrate:
Recurring vulnerability: Heavy rainfall events—whether natural or anthropogenic—can result in extensive loss of life.
Need for warning systems: Flash floods occur rapidly, leaving little time for evacuation.
Infrastructure resilience: Control systems, such as floodwalls and safer dam designs, can reduce the impacts.
Climate factors: Warmer air holds more moisture, increasing the likelihood of intense storms.
Today’s planners and residents must study these historic disasters closely to build stronger early-warning systems, infrastructure upgrades, and land-use policies that reduce future flood risk.
