After a might 1889 storm dumped practically 10 inches of rain top top Pennsylvania, the southern Fork Dam on the state"s little Conemaugh River might no longer organize the rain-swollen waters of Lake Conemaugh.

Remove of flood manage pipes in 1875 dilute the damaged dam also further and minimal flood control options. In 1879, Benjamin Ruff purchased Lake Conemaugh and also the surrounding property because that the wealthy clientele of his south Fork Hunting and Fishing Club. Had in the purchase was the distressed south Fork Dam. Ruff hastily repaired and "improved" the neglected dam. In doing so, he jeopardized the dam"s truth by lowering its elevation to construct a road to his clubhouse and blocking the dam"s spillways with display screens to prevent Lake Conemaugh"s fish from escaping.

In late might 1889, a short pressure device stalled end Pennsylvania, dumping an estimated 6 come 10 inch of rain on the Conemaugh flow Valley. On the morning of may 31, Elias Unger—president the the south Fork Fishing and Hunting Club—awoke to find that Lake Conemaugh"s water level was climbing rapidly. In the decade since Benjamin Ruff transformed the dam, debris had actually clogged the fish screens installed throughout its spillways, preventing the release of overabundance water. Regardless of the best efforts that Unger and also his employee to lull the anxiety on the dam, they were unable to divert the climbing water or clean the dam"s spillways. Castle warned the villages downstream together water started overtopping and also eroding the dam by early afternoon. Lake Conemaugh finally breached the dam around 3:00 p.m., sending approximately 3.8 billion gallons that water racing under the sink towards south Fork, Mineral Point, and also East Conemaugh. Once the overwhelming waters reached Johnstown, 14 mile downstream from the south Fork Dam, the wave surged with the city crushing terrified victim in a torrent of mud, broken trees, shattered homes and also furniture, barbed wire, and also debris.

That evening, the shocked inhabitants of the Conemaugh Valley started assessing the damage and searching for missing family members and also neighbors.
