On a stormy day in May of 1889, the South Fork Dam impounding Conemaugh Lake exploded, unleashing a 40-foot wall of water. The bustling industrial city of Johnstown, PA, in the valley below was reduced to a wasteland, killing more than 2,200. This heavily dramatized documentary reviews the factors that led to the dam's collapse, while dramatic reenactments and survivors' personal testimonies detail the horror.
Unfortunately the movie The Johnstown Flood is not yet available on HBO Max.
