Missouri River Flood of 1943

It’s High Time We Envisioned a Different River

In 1891, the Corps began building a six-foot deep navigation channel along the Missouri from the river’s mouth to Kansas City.  In order to constrict the Missouri’s channel area and deepen the stream to six feet, Army engineers erected thousands of pile dikes and revetments along the river’s bank line.  It took the Corps over four decades to complete that navigation channel.  On June 27, 1932, in a ceremony at Kansas City’s waterfront, the bombastic Secretary of War, Patrick Hurley, declared the channel open to barge traffic.  But barge operators stayed clear of the Missouri.  The railroads and highways between St. Louis and Kansas City carried products cheaper and faster than the river route.

In the mid-1930s, the Roosevelt administration authorized and funded the extension of the six-foot navigation channel northward to Sioux City.  Federal officials believed a longer navigation channel, which extended further inland and opened a larger market area to river traffic, would surely attract barge operators to the stream.  In 1940, the Corps completed the navigation channel to Sioux City.  But the hoped-for barge traffic still did not materialize because the railroads continued to provide a cost-effective alternative.

It’s A Tabletop: The Missouri Valley Spreads the Floodwaters

During the construction of the Missouri River navigation channel, the Army erected thousands of pile dikes and revetments to narrow, deepen, and straighten the wide, shallow, meandering stream.  Once the engineering works went into the river, the Missouri deposited its heavy silt-load on the downstream side of the structures.  Overtime, new, elevated lands appeared in the river’s floodplain.  Side channels, marshlands, and scour holes – everything that constituted the floodplain – filled with alluvium.  Accumulated sediments sharply reduced the floodplain’s ability to store floodwater.  Valley farmers benefitted from the newly accreted land.  They expanded their operations into the floodplain, planting row crops where native vegetation once grew.  The floodplain’s loss meant the farmer’s monetary gain.http://ecointheknow.com/wp-includes/js/tinymce/plugins/wordpress/img/trans.gif Continue Reading »
