The Johnstown Flood, sometimes referred to locally as Great Flood of 1889, occurred on Friday, May 31, 1889, after the catastrophic failure of the South Fork Dam, located on the south fork of the Little Conemaugh River, 14 miles (23 km) upstream of the town of Johnstown, Pennsylvania, United States. The dam ruptured after several days of extremely heavy rainfall, releasing 14.55 million cubic meters of water. With a volumetric flow rate that temporarily equaled the average flow rate of the Mississippi River, the flood killed 2,208 people and accounted for US$17,000,000 (equivalent to $553,696,296 in 2022) in damage.
The American Red Cross, led by Clara Barton and with fifty volunteers, undertook a major disaster relief effort. Support for victims came from all over the U.S. and eighteen foreign countries. After the flood, survivors suffered a series of legal defeats in their attempts to recover damages from the dam's owners. This led to American law changing from a fault-based regime to one of strict liability.
The city of Johnstown, Pennsylvania, was founded in 1800 by Swiss immigrant Joseph Johns (anglicized from "Schantz") where the Stonycreek and Little Conemaugh rivers joined to form the Conemaugh River. It began to prosper with the building of the Pennsylvania Main Line Canal in 1836 and the construction of the Pennsylvania Railroad and the Cambria Iron Works in the 1850s. By 1889, Johnstown's industries had attracted numerous Welsh and German immigrants. With a population of 30,000, it was a growing industrial community known for the quality of its steel.
The high, steep hills of the narrow Conemaugh Valley and the Allegheny Mountains to the east kept the development of Johnstown close to the riverfront areas. The valley had large amounts of runoff from rain and snowfall. The area surrounding the city is prone to flooding due to its location on the rivers, whose upstream watersheds include an extensive drainage basin of the Allegheny plateau. Adding to these factors, slag from the iron furnaces of the steel mills was dumped along the river to create more land for building. Developers' artificial narrowing of the riverbed to maximize early industries left the city even more flood-prone. The Conemaugh River, immediately downstream of Johnstown, is hemmed in by steep mountainsides for about 10 miles (16 km). A roadside plaque alongside Pennsylvania Route 56, which follows this river, proclaims that this stretch of valley is the deepest river gorge in North America east of the Rocky Mountains.
South Fork Dam and Lake Conemaugh
High above the city, the Commonwealth of Pennsylvania built the South Fork Dam between 1838 and 1853 as part of a cross-state canal system, the Main Line of Public Works. Johnstown was the eastern terminus of the Western Division Canal, supplied with water by Lake Conemaugh, the reservoir behind the dam. As railroads superseded canal barge transport, the Commonwealth abandoned the canal and sold it to the Pennsylvania Railroad. The dam and lake were part of the purchase, and the railroad sold them to private interests.
Henry Clay Frick led a group of Pittsburgh speculators, including Benjamin Ruff, to purchase the abandoned reservoir, modify it, and convert it into a private resort lake for their wealthy associates. Many were connected through business and social links to Carnegie Steel. Development included lowering the dam to make its top wide enough to hold a road and putting a fish screen in the spillway. Workers lowered the dam, which had been 72 feet high, by 3 feet. These alterations are thought to have increased the vulnerability of the dam. Moreover, a system of relief pipes and valves, a feature of the original dam which had previously been sold off for scrap, was not replaced, so the club had no way of lowering the water level in the lake in case of an emergency.
The Pittsburgh speculators built cottages and a clubhouse to create the South Fork Fishing and Hunting Club, an exclusive and private mountain retreat. Membership grew to include more than fifty wealthy steel, coal, and railroad industrialists. Lake Conemaugh at the club's site was 450 feet (140 m) in elevation above Johnstown. The lake was about 2 miles (3.2 km) long, about 1 mile (1.6 km) wide, and 60 feet (18 m) deep near the dam. The dam was 72 feet (22 m) high and 931 feet (284 m) long.
Events of the flood
On May 28, 1889, a low-pressure area formed over Nebraska and Kansas. By the time this weather pattern reached western Pennsylvania two days later, it had developed into what would be termed the heaviest rainfall event that had ever been recorded in that part of the U.S. The United States Army Signal Corps estimated that 6 to 10 inches (150 to 250 mm) of rain fell in 24 hours over the region. During the night, small creeks became roaring torrents, ripping out trees and debris. Telegraph lines were downed and rail lines were washed away. Before daybreak, the Conemaugh River that ran through Johnstown was about to overwhelm its banks.
On the morning of May 31, in a farmhouse on a hill just above the South Fork Dam, Elias Unger, president of the South Fork Fishing and Hunting Club, awoke to the sight of Lake Conemaugh swollen after a night-long heavy rainfall. Unger ran outside in the still-pouring rain to assess the situation and saw that the water was nearly cresting the dam. He quickly assembled a group of men to save the face of the dam by trying to unclog the spillway; it was blocked by the broken fish trap and debris caused by the swollen waterline. Other men tried digging a ditch at the other end of the dam, on the western abutment which was lower than the dam crest. The idea was to let more water out of the lake to try to prevent overtopping of the crest, but without success. Most remained on top of the dam, some plowing earth to raise it, while others tried to pile mud and rock on the face to save the eroding wall.
John Parke, an engineer for the South Fork Club, briefly considered cutting through the dam's end, where the pressure would be less to create another spillway, but eventually decided against it as that would have quickly ensured the failure of the dam. Twice, under orders from Unger, Parke rode on horseback to a telegraph office in the nearby town of South Fork to send warnings to Johnstown explaining the dangerous situation unfolding at the dam. Unfortunately, Parke did not personally take a warning message to the telegraph tower – he sent a man instead. However the warnings were not passed to the authorities in Johnstown, as there had been many false alarms in the past of the dam not holding against flooding. Unger, Parke, and the rest of the men continued working until exhausted to save the face of the dam; they abandoned their efforts at around 1:30 p.m., fearing that their efforts were futile and the dam was at risk of imminent collapse. Unger ordered all of his men to fall back to high ground on both sides of the dam where they could do nothing but watch and wait. During the day in Johnstown, the situation worsened as water rose to as high as 10 feet (3.0 m) in the streets, trapping some people in their houses.
Between 2:50 and 2:55 p.m. the South Fork Dam breached. A Lidar analysis of the Conemaugh Lake basin reveals that it contained 14.55 million cubic meters (3.843 billion gallons) of water at the moment the dam collapsed. Modern dam-breach computer modeling reveals that it took approximately 65 minutes for most of the lake to empty after the dam began to fail. The first town to be hit by the flood was South Fork; the town was on high ground, and most of the people escaped by running up the nearby hills when they saw the dam spill over. Between twenty and thirty houses were destroyed or washed away, and four people were killed.
Continuing on its way downstream to Johnstown, 14 miles (23 km) west, the water picked up debris such as trees, houses, and animals. At the Conemaugh Viaduct, a 78-foot (24 m) high railroad bridge, the flood was momentarily stemmed when debris jammed against the stone bridge's arch. But within seven minutes, the viaduct collapsed, allowing the flood to resume its course. However, owing to the delay at the stone arch, the flood waters gained renewed hydraulic head, resulting in a stronger, more abrupt wave of water hitting places downstream than otherwise would have been expected. The small town of Mineral Point, one mile (1.6 km) below the viaduct, was the first populated place to be hit with this renewed force. About thirty families lived on the village's single street. After the flood, there were no structures, no topsoil, no subsoil – only the bedrock was left. The death toll here was approximately sixteen people. In 2009, studies showed that the flood's flow rate through the narrow valley exceeded 420,000 cubic feet per second (12,000 m3/s), comparable to the flow rate of the Mississippi River at its delta, which varies between 250,000 and 710,000 cu ft/s (7,000 and 20,000 m3/s).
The village of East Conemaugh was the next populated area to fall victim to the flood. One witness on high ground near the town described the water as almost obscured by debris, resembling "a huge hill rolling over and over". From his idle locomotive in the town's railyard, the engineer John Hess heard and felt the rumbling of the approaching flood. Throwing his locomotive into reverse, he raced backward toward East Conemaugh, the whistle blowing constantly. His warning saved many people who reached high ground. When the flood hit, it picked up the still-moving locomotive off the tracks and floated it aside; Hess himself survived, but at least fifty people died, including about twenty-five passengers stranded on trains in the village.
Before hitting the main part of Johnstown, the flood surge hit the Cambria Iron Works in the town of Woodvale, sweeping up railroad cars and barbed wire. Of Woodvale's 1,100 residents, 314 died in the flood. Boilers exploded when the flood hit the Gautier Wire Works, causing black smoke seen by Johnstown residents. Miles of barbed wire became entangled in the debris in the flood waters.
Fifty-seven minutes after the dam collapsed, the flood hit Johnstown. Residents were caught by surprise as the wall of water and debris bore down, traveling at speeds of 40 miles per hour (64 km/h) and reaching a height of 60 feet (18 m) in places. Some people, realizing the danger, tried to escape by running towards high ground, but most were hit by the surging floodwater. Many people were crushed by pieces of debris, and others became caught in barbed wire from the wire factory upstream and/or drowned. Those who reached attics or roofs, or managed to stay afloat on pieces of floating debris, waited hours for help to arrive.
At Johnstown, the Stone Bridge, which was a substantial arched structure, carried the Pennsylvania Railroad across the Conemaugh River. The debris carried by the flood formed a temporary dam at the bridge, resulting in the flood surge rolling upstream along the Stoney Creek River. Eventually, gravity caused the surge to return to the dam, resulting in a second wave that hit the city from a different direction. Some people who had been washed downstream became trapped in an inferno as the debris that had piled up against the bridge caught fire; at least eighty people died there. The fire burned for three days. After floodwaters receded, the pile of debris at the bridge was seen to cover 30 acres (12 ha), and reached 70 feet (21 m) in height. It took workers three months to remove the mass of debris, the delay owing in part to the huge quantity of barbed wire from the ironworks entangled with the wreckage. Dynamite was eventually used.
The total death toll from the flood was calculated originally as 2,209 people, making the disaster the largest loss of civilian life in the U.S. at the time. This number of deaths was later surpassed by fatalities in the 1900 Galveston hurricane and the 9/11 attacks. However, as pointed out by historian David McCullough, a man reported as presumed dead had survived; Leroy Temple returned to Johnstown eleven years after the disaster and revealed he had extricated himself from the flood debris at the Stone Bridge, walked out of the valley, and relocated to Beverly, Massachusetts. After the revelation of Temple's survival, the official death toll was 2,208.
According to records compiled by the Johnstown Area Heritage Association, bodies were found as far away as Cincinnati, Ohio, and as late as 1911; 99 entire families died in the flood, including 396 children; 124 women and 198 men were widowed; 98 children were orphaned; and one third of the dead, 777 people, were never identified; their remains were buried at Johnstown's Grandview Cemetery.
On June 5, 1889, five days after the flood, the American Society of Civil Engineers (ASCE) appointed a committee of four prominent engineers to investigate the cause of the disaster. The committee was led by the esteemed James B. Francis, a hydraulic engineer best known for his work related to canals, flood control, turbine design, dam construction, and hydraulic calculations. Francis was a founding member of the ASCE and served as its president from November 1880 to January 1882. The committee visited the site of the South Fork Dam, reviewed the original engineering design of the dam and modifications made during repairs, interviewed eyewitnesses, commissioned a topographic survey of the dam remnants, and performed hydrologic calculations.
The ASCE committee completed their investigation report on January 15, 1890, but its final report was sealed and not shared with other ASCE members or the public. At ASCE's annual convention in June 1890, committee member Max Becker was quoted as saying, “We will hardly [publish our investigation] report this session, unless pressed to do so, as we do not want to become involved in any litigation.” Although many ASCE members clamored for the report, it was not published in the society's transactions until two years after the disaster, in June 1891. William Shinn, a former partner of industrialist Andrew Carnegie, became the new president of ASCE in January 1890. He gave the investigation report to outgoing Becker to decide when to release it to the public. Becker kept it under wraps until the time of ASCE's convention in Chattanooga, Tennessee, in 1891. The long-awaited report was presented at that meeting by James Francis. The other three investigators, William Worthen, Alphonse Fteley, and Max Becker, did not attend.
In their final report, the ASCE committee concluded the dam would have failed even if it had been maintained within the original design specifications, i.e., with a higher embankment crest and with five large discharge pipes at the dam's base. This claim has since been challenged. A hydraulic analysis published in 2016 confirmed that the changes made to the dam by the South Fork Fishing and Hunting Club severely reduced its ability to withstand major storms. Lowering the dam by as much as 3 feet (0.91 m) and failing to replace the discharge pipes at its base cut the dam's safe discharge capacity in half. This fatal lowering of the dam greatly reduced the capacity of the main spillway and virtually eliminated the action of an emergency spillway on the western abutment. Walter Frank first documented the presence of that emergency spillway in a 1988 ASCE publication. Its existence is supported by topographic data from 1889 which shows the western abutment to be about one foot lower than the crest of the dam remnants, even after the dam had previously been lowered as much as three feet by the South Fork Club. Adding the width of the emergency spillway to that of the main spillway yielded the total width of spillway capacity that had been specified in the 1847 design of William Morris, a state engineer.
In the years following the disaster, some survivors blamed the members of the South Fork Fishing and Hunting Club for their modifications to the dam. They were accused of failing to maintain the dam properly, so that it was unable to contain the additional water of the unusually heavy rainfall. The club was successfully defended in court by the firm of Knox and Reed (later Reed Smith LLP), whose partners Philander Knox and James Hay Reed were both club members. Knox and Reed successfully argued that the dam's failure was a natural disaster which was an Act of God, and no legal compensation was paid to the survivors of the flood. The club was never held legally responsible for the disaster. The perceived injustice aided the acceptance, in later cases, of "strict, joint, and several liability," so that even a "non-negligent defendant could be held liable for damage caused by the unnatural use of land."
Individual members of the South Fork Club, millionaires in their day, contributed to the recovery in Johnstown. Along with about half of the club members, co-founder Henry Clay Frick donated thousands of dollars to the relief effort. After the flood, Andrew Carnegie built the town a new library.
Popular feeling ran high, as is reflected in Isaac G. Reed's poem:
Many thousand human lives-
Butchered husbands, slaughtered wives
Mangled daughters, bleeding sons,
Hosts of martyred little ones,
(Worse than Herod's awful crime)
Sent to heaven before their time;
Lovers burnt and sweethearts drowned,
Darlings lost but never found!
All the horrors that hell could wish,
Such was the price that was paid for— fish!
The Johnstown Flood was the worst flood to hit the U.S. in the 19th century. 1,600 homes were destroyed, $17 million in property damage levied (approx. $497 million in 2016), and 4 square miles (10 km2) of downtown Johnstown were completely destroyed. Debris at the Stone Bridge covered thirty acres, and clean-up operations were to continue for years. Cambria Iron and Steel's facilities were heavily damaged; they returned to full production within eighteen months.
Working seven days and nights, workmen built a wooden trestle bridge to temporarily replace the Conemaugh Viaduct, which had been destroyed by the flood. The Pennsylvania Railroad restored service to Pittsburgh, 55 miles (89 km) away, by June 2. Food, clothing, medicine, and other provisions began arriving by rail. Morticians traveled by railroad. Johnstown's first call for help requested coffins and undertakers. The demolition expert "Dynamite Bill" Flinn and his 900-man crew cleared the wreckage at the Stone Bridge. They carted off debris, distributed food, and erected temporary housing. At its peak, the army of relief workers totaled about 7,000.
One of the first outsiders to arrive was Clara Barton, the founder and president of the American Red Cross. Barton arrived on June 5, 1889, to lead the group's first major disaster relief effort; she did not leave for more than five months. Donations for the relief effort came from all over the U.S. and overseas. $3,742,818.78 was collected for the Johnstown relief effort from within the U.S. and eighteen foreign countries, including Russia, France, Germany, Great Britain, Australia, and the Ottoman Empire.
Frank Shomo, the last known survivor of the 1889 flood, died March 20, 1997, at the age of 108.

Floods have continued to be a concern for Johnstown, which had major flooding in 1894, 1907, 1924, 1936, and 1977. The biggest flood of the first half of the 20th century was the St. Patrick's Day flood of March 1936. That flood also reached Pittsburgh, where it was known as the Pittsburgh Flood of 1936. Following the 1936 flood, the United States Army Corps of Engineers dredged the Conemaugh River within the city and built concrete river walls, creating a channel nearly twenty feet deep. Upon completion, the Corps proclaimed Johnstown "flood free."
The new river walls withstood Hurricane Agnes in 1972, but on the night of July 19, 1977, a severe thunderstorm dropped eleven inches of rain in eight hours on the watershed above the city and the rivers began to rise. By dawn, the city was under water that reached as high as 8 feet (2.4 m). Seven counties were declared a disaster area, suffering $200 million in property damage, and 78 people died. Forty were killed by the Laurel Run Dam failure. Another 50,000 were rendered homeless as a result of this "100-year flood". Markers on a corner of City Hall at 401 Main Street show the height of the crests of the 1889, 1936, and 1977 floods.

The Carnegie Library in Johnstown is now operated by the Johnstown Area Heritage Association, which has adapted it for use as the Johnstown Flood Museum.
Portions of the Stone Bridge have been made part of the Johnstown Flood National Memorial, established in 1969 and managed by the National Park Service. In 2008, the bridge was restored in a project including new lighting as part of commemorative activities related to the flood.
Combined with the failure of the Walnut Grove Dam less than a year later, the Flood brought national attention to the issue of dam safety.
Effect on the development of American law
Survivors of the flood were unable to recover damages in court because of the South Fork Club's ample resources. First, the wealthy club owners had designed the club's financial structure to keep their personal assets separated from it and, secondly, it was difficult for any suit to prove that any particular owner had behaved negligently. Though the former reason was probably more central to the failure of survivors' suits against the club, the latter received coverage and extensive criticism in the national press.
As a result of this criticism, in the 1890s, state courts around the country adopted Rylands v. Fletcher, a British common law precedent which had formerly been largely ignored in the U.S. State courts' adoption of Rylands, which held that a non-negligent defendant could be held liable for damage caused by the unnatural use of land, foreshadowed the legal system's 20th-century acceptance of strict liability.
