A report in 2000 showed that it handles an average discharge of 27 @.@ 3 m3 / s ( 960 cu ft / s ) into its mouth yearly , with a recorded high of 730 m3 / s ( 26 @,@ 000 cu ft / s ) in 1962 and a low of 0 @.@ 36 m3 / s ( 13 cu ft / s ) in 1966 . The same report estimated mean values for the minimum and maximum discharges for every two @-@ year , 10 @-@ year , and 100 @-@ year flood events , and minimum discharges for every two @-@ year , five @-@ year , and 100 @-@ year " drought " events :

 Since the beginning of the 20th century , the Missouri River has been extensively engineered for water transport purposes , and about 32 percent of the river now flows through artificially straightened channels . In 1912 , the USACE was authorized to maintain the Missouri to a depth of six feet ( 1 @.@ 8 m ) from the Port of Kansas City to the mouth , a distance of 368 miles ( 592 km ) . This was accomplished by constructing levees and wing dams to direct the river 's flow into a straight , narrow channel and prevent sedimentation . In 1925 , the USACE began a project to widen the river 's navigation channel to 200 feet ( 61 m ) ; two years later , they began dredging a deep @-@ water channel from Kansas City to Sioux City . These modifications have reduced the river 's length from some 2 @,@ 540 miles ( 4 @,@ 090 km ) in the late 19th century to 2 @,@ 341 miles ( 3 @,@ 767 km ) in the present day .

 The Missouri River is the longest river in North America . Rising in the Rocky Mountains of western Montana , the Missouri flows east and south for 2 @,@ 341 miles ( 3 @,@ 767 km ) before entering the Mississippi River north of St. Louis , Missouri . The river takes drainage from a sparsely populated , semi @-@ arid watershed of more than half a million square miles ( 1 @,@ 300 @,@ 000 km2 ) , which includes parts of ten U.S. states and two Canadian provinces . When combined with the lower Mississippi River , it forms the world 's fourth longest river system .
