Johnstown flood of July 20, 1977
Johnstown, PA (Cambria County) has an extensive history of major flooding. The "Great Johnstown Flood of May 1889" resulted in more than 2200 lives lost. The St. Patricks Day Flood from March 17-20th, 1936 also brought devestation to the region with 22 deaths in the Johnstown area.

History repeated itself in the early morning hours July 20th, 1977 when a thunderstorm complex stalled over the Johnstown area and Cambria County. Up to 12 inches of rainfall fell on the hills surrounding Johnstown, unleasing torrents of rainfall off the hillsides and into the Little Conemaugh River and smaller creeks. Similar to the 1889 event, a breach in a dam (Laurel Run Dam and Sandy Run Dam) sent a 10 foot high wall of water into town, sweeping away residents in their homes and cars.

When it was over, 77 lives were lost and damage was estimated at over $400 million dollars.

Below are a few of the many photos and images that we have saved in our archives of this event.
