Just prior to 8:00 a.m. on February 26, heavy-equipment operator Denny Gibson discovered the water had risen to the crest of the impoundment and the dam was "real soggy." At 8:05 a.m., the dam collapsed. The water obliterated the other two impoundments and approximately 132 million gallons of black waste water rushed through the narrow Buffalo Creek hollow.
In a matter of minutes, 125 were dead, 1,100 injured, and over 4,000 left homeless.
