The Flood Watch Girls of Johnstown, 1889May 31, 1889. The South Fork Dam above Johnstown, Pennsylvania had been leaking for days. Engineers said it would hold. It didn’t. At 3:10 PM, 20 million tons of water came rushing down the valley at 40 mph — a wall of water 60 feet high.
The only warning Johnstown received came from the Cambria Iron Works telephone exchange. Sixteen-year-old operator Anna Hudson and her sister Emma, nineteen, spotted the water surging through the valley from their second-story window. They didn’t run. For eight straight minutes they stayed at the switchboard, cranking every connected line — stores, homes, churches — and shouting the same urgent message: “The dam has broke! Run to the hills!”They managed to connect 112 calls before the building was ripped from its foundation.
Both girls drowned at the switchboard. That day, 2,209 people died — out of Johnstown’s 14,000 residents. Historians credit the Hudson sisters with saving more than 10,000 lives. The flood carried Emma’s body 14 miles downstream. She was found still clutching the headset cord. The first telegram sent from the ruins read: “Operators died at their posts.”
