The students will take a ranger-led hike into the lakebed and walk through the ruins of the South Fork Dam.


In addition to learning the history of what happened, students will utilize math skills to determine rate and flow speed of the waters coming from the broken South Fork Dam.


A partnership was formed with the Johnstown Flood National Memorial and the Johnstown Area Heritage Association. Out of this partnership an interdisciplinary curriculum based prgoram about the Great Johnstown Flood of 1889 was created, which provides a complete educational experience telling the story of the Johnstown Flood. This program takes the student from the story's beginnings-the South Fork Dam and Clubhouse of the South Fork Fishing and Hunting Club to the story's end-disaster, relief and the rebuilding of the city of Johnstown, Pennsylvania.
