On May 31, 1889, the South Fork Dam failed, releasing more than 4.8 billion gallons of water. The flood devastated Johnstown, Pennsylvania, and claimed the lives of over 2,200 people. Today, on National Dam Safety Awareness Day, we honor those lives by continuing efforts to improve dam safety across the country.

Johnstown Flood National Memorial preserves the remains of the dam and tells the story of one of the deadliest disasters in American history. The site invites visitors to reflect on the tragedy and the remarkable relief efforts that followed.
