To Tell The Truth: Will the Real Brigadier General John McMahon Please Stand Up?

In mid-October 2011, Brigadier General John McMahon, head of the Northwestern Division, wrote a widely circulated op-ed piece on the future management of the Missouri River.  In the article, the general acknowledged that the Army’s Missouri River hydraulic system of dams, levees, and channelization structures failed to halt this year’s flood and it would not stop the next super flood.  He wrote, “We know it [the hydraulic system] cannot handle the most extreme of flood events.”

McMahon stated that additional inputs of technology (such as dams or levees) would not solve the flooding problem along the Missouri.  Instead, the Missouri basin needed a new, non-structural flood mitigation program.  Such a program should include new zoning laws limiting or prohibiting construction in the floodplain, property easements to allow the river access to its former floodplain during high flow episodes, and the repositioning of levees.  The Missouri, according to McMahon, must have more room to maneuver.

Far and Wide: The Omaha-Council Bluffs Levees and the Flood of 2011

In 2011, an ocean of water poured down the Missouri River from the Dakotas and Montana.  The deluge represented the largest flood to strike the Missouri Valley since 1952.  At the peak of that earlier flood on April 18, 1952, the Missouri hurled 396,000 cubic feet per second past Omaha-Council Bluffs.  From Sioux City to the mouth of the Kaw River at Kansas City, the swollen river stretched from valley wall to valley wall – completely inundating the bottomlands.  A yellow, inland sea sank farmsteads, cropland, and rural roadways.  Because suburban housing developments and industrial parks did not yet exist in the river’s floodplain, high water devastated mostly agricultural land. Consequently, farmers bore the brunt of the financial losses associated with that flood.  Damage estimates ran as high as $179 million dollars (or $1.48 billion when adjusted for inflation).

Wetlands, Farmers, and Missouri River Floods

European-American agricultural settlement had a noticeable effect on the Missouri’s hydraulic regime.  During the steamboat era, roustabouts felled the valley’s forests to provide fuel for the hundreds of steamers that worked the river.  The loss of lowland timber caused the Missouri to rise higher, faster, and more frequently than it had in the years before the advent of steamboat traffic on the river.

Valley farmers also contributed to deforestation.  They knocked down the Missouri’s wooded fringes to acquire timber for log cabins, fence posts, roofing shingles, crude furniture, containers, and tool handles.  Settlers burned kindling in cooking and heating fires.  Not coincidentally, the most voluminous Missouri River floods in the nineteenth century occurred during the busiest years of the steamboat era.  Floods passed down the valley in 1844, 1857, 1858, 1862, 1867, 1872, 1874, 1875, 1878, and 1881.  Unknown to valley residents, or at least not acknowledged by them, they had to large extent brought down the floodwaters upon themselves.

Woodcutters and Floods: Steamboats, Deforestation, and the Missouri River

In 1819, the U.S. Army’s Western Engineer became the first steamboat to navigate the shallow, shifting Missouri.  On its voyage, the vessel encountered a number of problems that delayed its upstream passage, including sunken trees, sandbars, and mud (which found its way into the boiler).  Although, steamboat navigation did not have an auspicious beginning on the Mighty Mo, regular steamer traffic emerged along the Lower Missouri between St. Louis and Kansas City in the 1820s.

In 1831, the first steamboat traveled to the Upper Missouri (the river reach north and west of the Platte River confluence).  In the 1840s, steamboats replaced the slower, more cumbersome, keelboats along the entire length of the river.  By the 1850s, dozens of boats worked the Missouri between St. Louis and the head of navigation at Fort Benton, Montana Territory.  The 1850s witnessed the peak of Missouri river steamboat traffic.

Buffalo Roads and River Bottoms: Restoring an Ancient Ecology

An ancient mammalian road network once crisscrossed the northern reaches of what is now the United States.  Its trails had existed since the last ice age.  For thousands of years, large mammals – such as the wooly mammoth, saber-toothed tiger, sloth, bison antiques and later bison bison, cut pathways across the land.  Over the years, the mammal trails became deeper and wider from the incessant pounding of hooves.  Even before humans arrived on the continent, bison, deer, and elk located the routes of least resistance through the landscape.  After the peopling of North America, humans adopted those same roads for their own use.

King Corn and Its Minions: The Iowanization of Dakota

“So completely has the whole State passed beneath the plow, so quickly assumed the appearance of one vast farm, that one who thus studies the Iowa of to-day realizes with difficulty the strange picturesque wildness of fifty or sixty years ago…. The whole flora of the prairie went down to rise no more, to give place to plants of man’s selecting and to weeds…. Hosts of alien species occupied the ground.” – Thomas Macbridge, 1895 [Quote from Cornelia F. Mutel, "The Emerald Horizon: The History of Nature in Iowa," Iowa City: University of Iowa Press, 2008, p.75.]

Iowa once held a reputation for being a top pheasant hunting state.  In 1962, the Iowa Department of Natural Resources (DNR) estimated that bird numbers throughout the state stood at 65.9 pheasants per 30-mile brood survey route.  High pheasant populations resulted from ample habitat.  Birds found nesting sites, cover, and concealment in stands of timber and brush growing along fence rows or next to farm houses, in cattails encircling wetlands, and in the un-mowed ditches straddling public highways and dirt roads.  Good habitat enabled pheasants to survive Iowa’s occasionally brutal winters.
