parable length. Before the construction of dams, the river flooded twice each year – once in the "April Rise" or "Spring Fresh", with the melting of snow on the plains of the watershed, and in the "June Rise", caused by snowmelt and summer rainstorms in the Rocky Mountains. The latter was far more destructive, with the river increasing to over ten times its normal discharge in some years. The Missouri's discharge is affected by over 17,000 reservoirs with an aggregate capacity of some 141 million acre-feet (174 km3). By providing flood control, the reservoirs dramatically reduce peak flows and increase low flows. Evaporation from reservoirs significantly reduces the river's runoff, causing an annual loss of over 3 million acre-feet (3.7 km3) from mainstem reservoirs alone.

The United States Geological Survey operates fifty-one stream gauges along the Missouri River. The river's average discharge at Bismarck, 1,314.5 miles (2,115.5 km) from the mouth, is 21,920 cu ft/s (621 m3/s). This is from a drainage area of 186,400 sq mi (483,000 km2), or 35% of the total river basin. At Kansas City, 366.1 miles (589.2 km) from the mouth, the river's average flow is 55,400 cu ft/s (1,570 m3/s). The river here drains about 484,100 sq mi (1,254,000 km2), representing about 91% of the entire basin.

The lowermost gage with a period of record greater than fifty years is at Hermann, Missouri – 97.9 miles (157.6 km) upstream of the mouth of the Missouri – where the average annual flow was 87,520 cu ft/s (2,478 m3/s) from 1897 to 2010. About 522,500 sq mi (1,353,000 km2), or 98.7% of the watershed, lies above Hermann. The highest annual mean was 181,800 cu ft/s (5,150 m3/s) in 1993, and the lowest was 41,690 cu ft/s (1,181 m3/s) in 2006. Extremes of the flow vary even further. The largest discharge ever recorded was over 750,000 cu ft/s (21,000 m3/s) on July 31, 1993, during a historic flood. The lowest, a mere 602 cu ft/s (17.0 m3/s) – caused by the formation of an ice dam – was measured on December 23, 1963.

High silt content makes the Missouri River (left) noticeably lighter than the Mississippi River (right) at their confluence north of St. Louis.
The Rocky Mountains of southwestern Montana at the headwaters of the Missouri River first rose in the Laramide Orogeny, a mountain-building episode that occurred from around 70 to 45 million years ago (the end of the Mesozoic through the early Cenozoic). This orogeny uplifted Cretaceous rocks along the western side of the Western Interior Seaway, a vast shallow sea that stretched from the Arctic Ocean to the Gulf of Mexico, and deposited the sediments that now underlie much of the drainage basin of the Missouri River. This Laramide uplift caused the sea to retreat and laid the framework for a vast drainage system of rivers flowing from the Rocky and Appalachian Mountains, the predecessor of the modern-day Mississippi watershed. The Laramide Orogeny is essential to modern Missouri River hydrology, as snow and ice melt from the Rockies provide the majority of the flow in the Missouri and its tributaries.

The Missouri and many of its tributaries cross the Great Plains, flowing over or cutting into the Ogallala Group and older mid-Cenozoic sedimentary rocks. The lowest major Cenozoic unit, the White River Formation, was deposited betw
