Visit Potter-Tioga The Johnstown Flood

The Johnstown Flood

Over 130 years ago...
In the waning years of the nineteenth century, the steel barons from Pittsburgh enjoyed a private retreat in the mountains of Cambria County. Known as the South Fork Fishing and Hunting Club, the members included Andrew Carnegie and Henry Clay Frick. The club boasted a multi-acre lake, boathouses and cottages. A large clubhouse served as a hotel and restaurant for members and their guests. Life was easy along the lake until the rains came that day. The storm began on Memorial Day and continued through the night.

On May 31, 1889, rising water in the lake breached the South Fork Dam, sending twenty million tons of water roaring through the Conemaugh Valley. The massive wall of water destroyed everything in its path. Houses, railroad cars and other debris all became part of the deadly mix that crashed into Johnstown and literally swept the town away. When it was all over, 2,209 people were dead; but from the destruction rose a spirit of survival and commitment that is still alive in Johnstown.

Visiting the following sites and points of interest is an unforgettable journey through a poignant time in Johnstown’s history; here the lessons of the past still apply today.

Learn the shocking story of the Great Johnstown Flood of 1889 and Johnstown’s remarkable recovery.
Johnstown Flood Attractions
Johnstown Flood National Memorial

See the remains of the South Fork Dam!

This National Park Service Site is located at the ruins of the South Fork Dam that burst May 31, 1889. The dam unleashed 20,000,000 tons of water that devastated Johnstown. 

A visit to the Johnstown Flood National Memorial puts into perspective the scope and size of the disaster. The Lake View Visitor Center has two floors of exhibits and a life-size “debris wall” that dramatically illustrates the flood wave that devastated Johnstown. The film Black Friday chillingly recreates that day in 1889. Visitors can also explore trails around the dam's remains and picnic areas. 

There is no entrance fee. 




Johnstown Flood Museum
Johnstown Flood Museum

Watch the Academy-Award® winning film!

The Johnstown Flood Museum recreates the 1889 Flood with exhibits, artifacts and the Academy Award® winning film, The Johnstown Flood. This film is the only museum-commissioned documentary that has won an Academy Award® in the short subject documentary category. The museum not only tells the story of the flood, but the town's triumphant recovery.

The museum is located in the former Cambria Library. The building was built after the flood using funds provided by Andrew Carnegie, a member of the South Fork Fishing & Hunting Club, which owned the South Fork Dam.

The museum includes a relief map that illustrates the path of the flood down the Conemaugh Valley by using light and sound effects. A featured exhibit is an original "Oklahoma House", one of the first types of pre-fabricated temporary houses sent to Johnstown for flood survivors.

The Johnstown Flood story

The Johnstown Flood story made the big screen!

In 2003, Johnstown Flood, narrated by actor Richard Dreyfuss, was released straight to DVD.

Much of the footage from the Johnstown Flood National Memorial’s film Black Friday was taken from the 1926 silent film, The Johnstown Flood, which starred Janet Gaynor and George O’Brien.

The animated short from 1946, Mighty Mouse and The Johnstown Flood, features our rodent hero using super-hypnosis to turn back time and “save the day”.
