The Great Flood of 1844

The Great Flood of 1844 was the largest known flood by discharge on the lower Missouri River in recorded history, cresting in June and July 1844 after weeks of heavy spring rain across the basin.¹² At Westport Landing — the river-bottom trading point that would become Kansas City — the flood is estimated to have discharged about 625,000 cubic feet per second, washing away the homes, farms, and trading improvements of the early French settlements clustered near the Missouri–Kaw confluence.¹ Nearly two centuries later it remains the benchmark “flood of record” for the lower Missouri basin, the event against which the later 1903 and 1951 floods are measured.¹²

The flood (June-July 1844)

Heavy rains soaked the lower Missouri River Valley through May and June 1844, with monthly rainfall totals reported from roughly 18 inches at St. Louis to about 27 inches at Fort Scott, Kansas.¹ A succession of violent storms beginning in early June drove the rivers over their banks; by mid-June the bottomlands along the Missouri and the Kansas (Kaw) rivers were inundated, and the waters did not begin to recede until late June, with the crisis easing into mid-July.¹ Because the region had almost no levees at the time, the floodwaters spread far beyond the normal channels.¹

The flood produced the largest discharge ever recorded on the Missouri–Upper Mississippi system, with about 1,300,000 cubic feet per second measured for the Mississippi at St. Louis.¹ On the Kaw, experts have called 1844 the worst flood in that river’s recorded history, with floodwaters reported reaching what is now the Kansas State University campus in Manhattan, far above the normal stream level.¹ The June 1844 event is regarded as the greatest known flood in the lower Missouri basin.²

Impact on the early Kansas City area

At Westport Landing — the Missouri River landing in the river bottoms that anchored the future Kansas City — the 1844 flood was the largest of the region’s major historic floods by rate of discharge, estimated at roughly 625,000 cubic feet per second.¹ The flood destroyed the small French farming and trading community that had grown up in the bottoms around the Chouteau interests near the Missouri–Kaw confluence (the area of the future West Bottoms and Kaw Point). A contemporary Catholic priest recorded that after the flood “washed away all of their little homes and improvements,” the little French clearings fell silent but for birdsong.¹

The human toll fell hardest on the Wyandot, recently removed to the confluence area; roughly 100 deaths were attributed to disease that followed the flood near what became Kansas City, Kansas.¹

How it shaped KC settlement (higher ground)

The disaster reinforced a lesson the river bottoms had already taught. After an earlier major flood in 1826, François Chouteau had relocated his trading post to higher ground near the riverfront in the vicinity of what became Troost Avenue.³ The 1844 flood, which destroyed the residential community that grew up around the post, drove home the hazard of building in the bottoms and pushed the young settlement’s commercial and residential center toward the bluffs and higher ground above the river — the pattern that would shape the town of Kansas as it organized in the following decade.¹³

The flood also had a regional realignment effect: it formed a large sandbar in front of the Wayne City Landing at Independence, Missouri, prompting traffic and settlers to move farther west to Westport Landing — a shift that strengthened the landing’s role as a trailhead and helped concentrate the trade that would build Kansas City.¹

Legacy (the benchmark flood; later 1903 + 1951 comparisons)

The Great Flood of 1844 remains the flood of record by discharge for the lower Missouri basin and is the standard against which later major floods are compared.¹² By discharge, subsequent floods on the system measured well below 1844: about 782,000 cubic feet per second in 1951 and about 1,030,000 cubic feet per second in 1993, against roughly 1,300,000 in 1844.¹ The catastrophic 1903 and 1951 floods, which devastated a far more developed West Bottoms and the surrounding metro, are routinely measured against the 1844 benchmark in flood-history accounts of the region.¹²

Significance to Kansas City

The Great Flood of 1844 is a foundational event in Kansas City’s pre-city history. It destroyed the first European-American settlement layer in the river bottoms, accelerated the consolidation of trade at Westport Landing over rival landings, and embedded an early, hard-won understanding that the bottoms were no place to build a city center — a calculus that recurred through the 1951 flood and the eventual armoring of the West Bottoms with levees. As the basin’s flood of record, it still frames how Kansas City understands its own relationship to the Missouri and Kaw rivers.
