Floods in the United States before 1900 is a list of flood events that were of significant impact to the country, before 1900. Floods are generally caused by excessive rainfall, excessive snowmelt, and dam failure.
Prehistoric events
Kankakee Torrent
The Kankakee Torrent was a catastrophic flood that occurred between 14,000 and 18,000 years ago, resulting from the breach of a large glacial lake formed by the melting of the Wisconsin Glacier. The origin of the flood may have been prehistoric Lake Chicago, it may have come from further east, near what is today the center of the Lower Peninsula of the state of Michigan. The torrent carved out a channel that is currently followed by the Kankakee River and Illinois River. It also appears to have pushed the course of the Ohio River further south and the Mississippi River further west. The bluffs carved by the torrent can be seen at Starved Rock State Park and Kankakee River State Park. In both parks, smaller streams flow over waterfalls before they join the main river, a phenomenon known as hanging tributaries.
Glacial River Warren
Glacial River Warren drained Lake Agassiz in central North America through a series of floods about 9,700 years ago. The enormous outflow from this lake carved a broad valley now occupied by the much smaller Minnesota River and the Upper Mississippi River. Agassiz was a huge body of water, up to deep, and at various times covering areas totaling over .Lusardi, Quaternary Glacial Geology , pp. 3–4; Sansome, Minnesota Underfoot, p. 175. The area actually inundated at one time was somewhat less. Blocked by an ice sheet to the north, the lake water rose until about 9,700 years ago, when it overtopped the Big Stone Moraine, a ridge of glacial drift left by the receding glacier, at the location of Browns Valley, Minnesota. The lake's outflow was catastrophic at times,Fisher, River Warren Boulders , pp. 348, 350. and carved a gorge through the moraine a mile (1.6 km) wide and deep, which is now known as the Traverse Gap.Sansome, Minnesota Underfoot, pp. 174–75; Upham, The Glacial Lake Agassiz , p. 14-17. While active, Glacial River Warren cut and eroded a bed up to wide and deep.Sansome, Minnesota Underfoot, pp. 118–19. This has left a valley which starts at Traverse Gap near Browns Valley, Minnesota, goes southeast to Mankato, then turns northeast to the Twin Cities.
Maumee Torrent
The Maumee Torrent was caused by the draining of glacial Lake Maumee, the ancestor of present-day Lake Erie. The flood carved a channel up to 2 miles wide, which today is the site of the Little River in Allen County, Indiana.
Missoula floods
The Missoula floods are a series of flood outbursts that took place near the end of the last ice age. Much of the unique geography of eastern Washington, named the Channeled Scablands, is thought to have been carved during this period. A glacial lake, located on the Clark Fork River in western Montana is thought to have been the source. The glacial lake outburst floods are thought to have been the result of periodic sudden ruptures of the ice dam on the Clark Fork River that created Glacial Lake Missoula. After each ice dam rupture, the waters of the lake would rush down the Clark Fork and the Columbia River, inundating much of eastern Washington and the Willamette Valley in western Oregon. After the rupture, the ice would reform, recreating Glacial Lake Missoula once again.
Bonneville flood
The Bonneville flood was a catastrophic flood 14,000 years ago, which involved massive amounts of water inundating parts of southern Idaho and Eastern Washington along the course of the Snake River. Unlike the Missoula Floods, which occurred during the same period, the Bonneville Flood happened only once. The flood is believed to be the second largest flood in known geologic history.
Sixteenth century
Flood of March 1543 Hernando DeSoto's party was passing through a village at the confluence of the Mississippi River and Arkansas River on March 18 when the rivers flooded. The high water only allowed passage by canoe and inundated fields surrounding the town. Brad Edmondson. 1927 Mississippi River flood. Retrieved on 2006-11-30.

New Hampshire/Maine flood – October 1785 In New Hampshire, a significant flood struck the Cocheco, Baker, Pemigewasset, Contoocook and Merrimack rivers on October 23 which established records at Lowell which held until 1902. The Androscoggin River flooded significantly, which destroyed many homesteads in what would become Bethel, Maine. Those that survived the flood moved uphill into less valuable, plots. Turner's first mill was destroyed during this inundation. Environmental History of the Androscoggin River, Maine and New Hampshire
Great Pumpkin flood – October 1786 Received its name due to the pumpkins that were washed away in the flood on October 5. It was a major flood in the Susquehanna River basin.Stephen F. Miller Jr. The Chronological History of Natural Disasters in North Central Pennsylvania. Retrieved on 2006-11-30.
Red River of the South flood – 1800 According to the Caddo tribe, a "great flood" moved down the river and reinforced the "Great Log Raft" on the river. This raft was a natural dam that increased water levels on some of the Red River tributaries. This process formed Caddo Lake.WFO SHV – Hydrology Information

Androscoggin Freshet – 1843 A flood along the Androscoggin swept the town of Jay's sawmill downstream.
Great Flood of 1844 The Great Flood of 1844 is the biggest flood ever recorded on the Missouri River and Upper Mississippi River in terms of discharge. This flood was particularly devastating since the region had little or no levees at the time. Among the hardest hit were the Wyandot who lost 100 people in the diseases that occurred after the flood. The flood also is the highest recorded for the Mississippi River at St. Louis. After the flood, Congress in 1849 passed the Swamp Act providing land grants to build stronger levees.Jackson County 175th Anniversary Timeline
Androscoggin flood – 1846 A flood along the Androscoggin River carried away the bridge in Durham, Maine. This reinstituted ferry service across the river.
Potomac flood of October 1847 A significant flood struck the Potomac basin, part of a major flood event which encompassed Pennsylvania, Ohio, Maryland, and Virginia. Damage along the C&O Canal was worst between lock #7 and Widewater, from Great Falls to Pennyfield Lock, Point of Rocks to Dam #4, and surrounding Dam #5. Damages to the canal for the year, which included another flood that November, totaled US$48,000 (1847 dollars).Potomac Riverkeeper – flood History
Sauvé's Crevasse – 1849 This was the last of the annual spring Mississippi River floods to swamp New Orleans.
Red River of the South flood – August 1849 A flood that appears to have been caused by a tropical cyclone led to the flood of record on the Red River of the South. This flood shifted the river to its present course, moving out of Natchitoches. A remnant of the river known as Cane River extends from Grand Ecore to Colfax.
Late Nineteenth century
Midwest and Plains U.S. – 1851 The Flood of 1851 occurred after record-setting rainfalls across the U.S. Midwest and Plains from May to August, 1851. Hardest hit was the State of Iowa, where the city of Des Moines was virtually destroyed, with significant flooding extending to the Lower Mississippi River basin. Historical evidence suggest flooding occurred in the eastern Plains, from Nebraska to the Red River basin, but these areas were sparsely settled in 1851. Heavy rainfall also occurred in the Ohio River basin.
Northeast flood – April 1852 In New Hampshire, the Winnipesaukee, Pemigewasset, Contoocook, Blackwater and Ashuelot Rivers went into flood. The Merrimack River at Concord reached its highest levels in nearly 70 years. A flood with higher waters than 1847 surged down the Potomac River. The worst damage was witnessed between Georgetown and Seneca, with breaches at the abutments of Dams 3 and 4 in Maryland, and Dam 6 in Virginia. Damage was estimated at US$80,000 (1852 dollars).
Susquehanna River flood – September 1861 Torrential rain and a logjam initiated the flood at the Susquehanna on September 28. Debris in the flood waters swept the Keating railroad bridge away. Sinnemahoning cemeteries were flooded, and some of its bodies moved downstream.
The Great Flood of 1862
The largest flood in the recorded history of Oregon, Nevada and California. It began in Oregon in November 1861 after weeks of continuous precipitation, flooding the communities on the Willamette River.
California Beginning on December 24, 1861, it rained for almost four weeks. The largest flood in California's recorded history occurred from January 9–12, 1862. The entire Sacramento and San Joaquin Valleys were inundated for an extent of , averaging in breadth. The rain created an inland sea in Orange County, lasting about three weeks with water standing deep up to from the river.
Nevada Flooding began in December, 1861 in Carson Valley from a series of storms in the upper Carson River basin. By January 2, 1862, the town of Dayton and the area surrounding it had been flooded. Samuel Young of Aurora recorded in his diary that the snow and rain had fallen for twenty six days out of thirty since December 24, 1861.
Androscoggin River flood – 1863 A large flood along the river destroys the bridge in East Turner, Maine.
Saxby Gale flooding – 1869 The combination of the extreme high tide and a hurricane on October 4–5 was dubbed the Saxby Gale. The resultant flooding set records on the East Coast of the United States. The Federal Emergency Management Agency (FEMA) named it a 100-year flood for the Schuylkill River in Philadelphia, cresting higher than Hurricane Agnes in 1972.Placard at Fairmount Waterworks Washington, DC, was also hit hard.
Mill River flood – May 1874 It rained significantly on May 16, 1874, in western Massachusetts. The earthen dam suddenly gave way. A large section of the east bank of the Mill River slid away and was sent downstream. The dam's gatekeeper mounted a horse and rushed down the valley to warn Williamsburg of what was to come. The gatekeeper's wife watched from their cabin as the dam exploded upward. Four riders galloped down the valley as fast as possible to warn people of the oncoming flood. Some residents fled to higher ground, while others refused to believe the awful news. Many never heard the warning. A tall flood swept everything away. Damage totaled US$1 million and 144 people died.NESEC – floods
