'A Roar Like Thunder"
On June 1, 1889, Americans woke to the news that Johnstown,
Pennsylvania, had been devastated by the worst inland flood
in the nation's history. More than 2,200 were dead, with thousands more injured. When the full story of the flood came to
light, many realized that this was more than a "natural" disaster—that greed and self-interest were powerful accomplices.
Johnstown in 1889 was a steel company town of German and
Welsh families. It was a growing and industrious community
of 30,000, known for the quality of its steel. Founded in 1794,
Johnstown began to prosper with the building of the Pennsylvania Mainline Canal in 1834 and the arrival of the Pennsylvania Railroad and the Cambria Iron Company in the 1850s.
There was one drawback to living in the city. Johnstown had
been built on a floodplain at the fork of the Little Conemaugh
and Stony Creek rivers. Over the years the growing city had
stripped forests from the surrounding hills and narrowed the
river banks t o gain building space. Without the trees to slow
runoff, rainwater was forced into the constricted river channel; heavy annual rains had dramatically increased flooding.
And, there was something else. Fourteen miles up the Little
Conemaugh, two-mile-long Lake Conemaugh was held on the
side of a mountain—450 feet higher than Johnstown—by the
old South Fork Dam. The dam was poorly maintained, and
there was talk that the dam might not hold. But it always had,
and the supposed threat became a standing joke around t o w n .
On the afternoon of May 31 t o w n residents heard a low rumble that grew to a "roar like thunder." After a night of heavy
rain the South Fork Dam had finally broken, sending 20 million
tons of water crashing down the narrow valley. Most people
never saw anything until the 36-foot wall of water, boiling
with huge chunks of debris, rolled over them at 40 miles per
hour, consuming everything in its path. Those w h o saw the
water said it "snapped off trees like pipestems," "crushed
houses like eggshells," and "threw around locomotives like so
much chaff." A violent wind preceded it, blowing down small
buildings. Making the wave even more terrifying was the black
pall of smoke and steam from burst boilers that hung over it—
the "death mist" remembered by survivors.
Thousands of people desperately tried t o escape the wave,
but they were slowed as in a nightmare as the deepening
water covered the t o w n . One observer from a hill said the
streets "grew black with people running for their lives." Some
remembered reaching the hills and pulling themselves out of
the flood path seconds before it overtook them. Those caught
by the wave found themselves swept up in a torrent of oily,
yellow-brown water, surrounded by tons of grinding debris
that crushed some and provided rafts for others. Many became
helplessly entangled in miles of barbed wire from a destroyed
wire works. People indoors when the wave struck raced upstairs seconds ahead of the rising water, which reached the
third story in many buildings. Some never had a chance, as
homes were crushed or ripped from foundations, adding t o
the churning rubble. People clinging t o debris struggled t o
keep their balance as their rafts pitched in the flood.
It was over in 10 minutes—but for some the worst was still t o
come. Thousands of people in attics or on rooftops of buildings
that withstood the initial wave were threatened by the 20-foot
current tearing at the foundations. In the growing darkness
they watched buildings topple, not knowing if theirs would
last the night.
The most harrowing experience for hundreds came at the
stone railroad bridge below the junction of the rivers (see diagram below "The Flood Paths"). Thousands of tons of debris
scraped from the valley, along with a good part of Johnstown,
piled up against the arches. The 45-acre mass held homes,
machinery, freight cars, railroad track, bridge sections, boilers,
telegraph poles, trees, animals, and hundreds of people. The
oil-soaked jam was immovable, held against the bridge by the
current and bound tight by the barbed wire.
Those who were able scrambled over the heap toward shore.
Many were trapped in the wreckage or snared in the wire,
unable to move. Then the oil caught fire. As rescuers worked
in the dark to free people, flames spread over the whole mass,
burning with "all the fury of hell," according to a Johnstown
newspaper. More than 80 people died at the bridge, some
still in their own homes.
The next morning an eerie silence hung over Johnstown. The
water receded during the night, leaving vast heaps of rubble
in the streets (where there were streets). Entire blocks were
razed. Hundreds of people, alive and dead, lay buried in debris
and mud.
Many bodies were never identified, and hundreds of the missing were never found. Disease followed in the wake of the
flood, and typhoid added 40 more lives to the 2,209 lost in the
flood. Emergency morgues and hospitals were set up, and commissaries distributed food and clothing. The nation responded
to the disaster with an outpouring of time, money, food, and
clothing. Contributions from the United States and other countries totaled more than $3,700,000.
Property damage was $17 million. The cleanup operation took
years, w i t h bodies still being found months (and years) after
the flood. The city regained its population and rebuilt its manufacturing centers, but it was years before Johnstown fully
recovered.
Retreat for the Rich
The Flood Paths
A Wild Ride
Aid from the Red Cross
Unknown Flood Victims
The South Fork Fishing
and Hunting Club was
an exclusive and somewhat secretive retreat for
the Pittsburgh rich. They
bought an abandoned
reservoir, repaired the old
dam, raised the lake level,
and built a clubhouse and
cottages. The members
enjoyed hunting, sailing,
and two excursion steamers that plied the lake. The
lack of adequate maintenance on the dam weakened it dangerously.
When the flood hit Johnstown the wave of water
divided: part followed the
river channel and the rest
headed downtown. Large
buildings split that second
wave again. Water roared
down Clinton and Jackson
streets; the rest plowed
directly through town.
This central wave crashed
into the sheer hillside at
Stony Creek, causing a
backwash up the river
and a violent whirlpool
above the stone bridge.
Victor Heiser, 16, recalled:
"The townspeople, like
those who live in the shadow of Vesuvius, grew calloused to the possibility of
danger." Heiser was in the
family barn when the
flood struck and saw his
home, with his parents
in it, crushed and swept
away. Clinging to the barn
roof, he had a wild ride
down the Conemaugh
River and then up Stony
Creek on the backwash,
ending up in Kernville.
Clara Barton, "Angel of
the Battlefield," and her
staff of 50 doctors and
nurses arrived in Johnstown five days after the
flood. It was the first test
of her newly formed
American Red Cross. She
surveyed the injured, set
up hospital tents, built six
"Red Cross hotels" for the
homeless, and distributed
food, clothing, and medicine. Although 67 she
worked hard, staying in
Johnstown until October.

"Our Misery Is the Work of Man'
Warnings about a possible f l o o d reached the people of Johnstown three times in t h e hours before
the dam broke—but they had heard those kinds of
warnings before. The South Fork Dam, one of the
largest earthen dams in the world, had always held
during high water. Besides, wasn't the dam maintained by some of the richest men in America?
The South Fork Fishing and Hunting Club, made up
of Pittsburgh industrialists and businessmen such as
Andrew Carnegie and Andrew Mellon, had bought
the lake and dam nine years earlier to use as a summer retreat. The reservoir was originally built to supply water for the Pennsylvania Mainline Canal, and
the dam met accepted engineering practices of the
time. But the canal system was obsolete by the time
the dam was completed in 1853, and the Pennsylvania Railroad bought it four years later. In 1862 a
break occurred near the discharge pipes (see diagram at right), draining the lake, but little damage
resulted because the lake level was low at the time.
The railroad abandoned the dam and it deteriorated until 1879, when it was bought by the South
Fork Club.
plowing the earth to raise it, some digging another
spillway at the other end, and some trying to plug
leaks with whatever materials they could find.
At first the 72-foot-high dam frightened some residents of Johnstown. Said one: "No one could see
the immense height to which that artificial dam had
been built without fearing the tremendous power of
the water behind i t . . . People wondered and asked
why the dam was not strengthened, as it certainly
had become weak, but nothing was done, and by
and by they talked less and less about it." Others,
realizing their continuing vulnerability, called the
dam " t h e sword of Damocles hanging over Johnst o w n . " Daniel J. Morrell, president of Cambria Iron,
worried about the dam. Benjamin Ruff (South Fork
Club's first president) refused Morrell's requests that
the dam be strengthened: "You and your people
are in no danger from our enterprise."
John Parke, an engineer for the South Fork Club,
briefly considered cutting through the dam's end,
where the pressure w o u l d be less. Feeling that he
would be held responsible for flooding the valley,
Parke decided against it. Unger, Parke, and the others worked until they were exhausted.
UNIVERSITY OF PENNSYLVANIA
On the morning of May 31, 1889, in a farmhouse
above the dam, Elias Unger (current president of
the South Fork Club) awoke to the sight of a lake
swollen after a night of torrential rain. Unger rushed
t o the dam t o assess the situation. Horrified, he
saw t h a t the water was nearly cresting the dam.
Unger acted quickly in an effort to save it. Soon a
group of men were atop the South Fork Dam—some
South Fork Club's maintenance of dam: 1 Fish trap
built across the spillway. In
heavy rains, debris clogged
trap and spillway. 2 Twoto four-foot sag developed
along dam wall; club did
not repair it.
3 Dam height reduced
by one- to three-feet. This
and the sag meant that
the center of dam—the
part bearing the greatest
pressure and which should
have been its highest
point—was only four feet
above the bottom of the
spillway. 4 Stone "riprap"
covering the face of dam
poorly maintained. 5 Original discharge pipes not
replaced. Culvert holding
pipes carelessly filled in.
John Parke, the club engineer who tried in vain to
save the dam, rode his
horse at breakneck speed
to South Fork to warn
Johnstown.
When the dam started to break at 3:10 p.m., Parke
wrote later, "the fearful rushing waters opened the
gap w i t h such increasing rapidity that soon after the
entire lake leaped out. . . . It took but forty minutes
t o drain that three miles of water." One observer
said the water "roared like a mighty battle." Twenty
million tons of water took its natural course, dropping 450 feet in 14 miles, at times in a wall 70 to 75
feet high and reaching speeds of 40 miles per hour.
Telegraph lines were down, and Johnstown received
no more warning messages. In 57 minutes the wave
engulfed the t o w n . More than 2,200 people were
unaware that death was moving down the valley.
Two worn abutments are
all that remain of what
was one of the largest
earthen dams in the
world in 1889. The old
lakebed behind the dam
and the quiet Little Conemaugh River give little
indication of the awesome power released on
the day that the dam
broke, causing the deadliest inland flood in the
nation's history.

The South Fork Dam did
not instantly burst (left).
Observers remember the
water gouging out a "big
notch," then cutting down
rapidly through the earth.
"The whole dam seemed
to push out all at once. Not
a break, just one big push."
Lake Conemaugh broke t h r o u g h t h e South Fork

The debris actually spared Johnstown even worse
destruction, as it slowed t h e wave t o a m a x i m u m

wave. The rest of the town
was reduced to mud flats.
Destruction of the wire
works released miles of
barbed wire, adding to the
terror of those caught in
the flood.

A jam at stone bridge caused a 10- to 30-foot lake
over Johnstown. The fire caused by oil and hot coals
burned for two days. More than 80 people died here.
As soon as the water receded, rescue workers began
searching for survivors and bodies. Some waited days
to be rescued.
Locomotives at East Conemaugh trainyard were tossed
