  • The Johnstown flood of 1977 was a major flood which began on the night of July 19, 1977, when heavy rainfall caused widespread flash flooding in Cambria County, Pennsylvania, United States, including the city of Johnstown and the . On July 19, 1977, a deluge of rain hit the area around Johnstown during the night. Nearly 12 inches (300 millimetres) of rain fell in 24 hours when a thunderstorm stalled over the area, and six dams in the area over-topped and failed. The largest dam to fail was the Laurel Run Dam, releasing over 101 million U.S. gallons (380,000 cubic meters) of water that poured through the village of Tanneryville, killing 41 people. The combination of the other five dams released another 27 million US gallons (100,000 m3), not counting the water from rains. Well over 128 million US gallons (480,000 m3) of water from the dams alone poured down the valley, and by dawn Johnstown was inundated with six feet (1.8 m) of water. The channel improvements were designed to carry 81,500 cu ft/s (2,310 m3/s), but the 1977 flood discharge was measured as 115,000 cu ft/s (3,300 m3/s). Ron Shawley, executive director of Laurel Highland's Historical Village, returned to Johnstown on July 20 and stated "It was like somebody dropped an atomic bomb on Johnstown" and that "I questioned what kind of force it would take to do that."
