Bob Criss doesn\u2019t claim to walk on<\/em> water, but on a walk over <\/em>the water, he has a lot to say about current [pun intended] issues. On a windy, June-morning stroll across historic Eads Bridge just north of downtown St. Louis, Criss offered a guided tour that combined science [he\u2019s a hydrologist and professor at Washington University in St. Louis], history, a bit of math and a large dollop of politics.<\/p>\n

A walk across Eads Bridge is an experience that, it\u2019s probably safe to say, most residents of and visitors to St. Louis routinely miss, even though the iconic structure\u2014one of the first major bridges across the Mississippi\u2014is \u00a0just one street-crossing from the Arch. That\u2019s unfortunate, because the view from the refurbished Eads Bridge pedestrian lane offers a perspective that you can\u2019t get from the top of the Arch or from a car window at 50 mph.<\/p>\n

Mississippi River at St. Louis, 1837<\/figcaption><\/figure>\n

For example, ask someone how wide the Mississippi is at St. Louis, and the answer will probably be about a mile. That measurement, says Criss, was nearly correct in the mid-1800\u2019s, when a young engineer named Robert E. Lee measured its width at 3500 to 4500 feet at St. Louis. Today, however, the river is significantly narrower, and Criss challenged participants on our walking tour to calculate its width by counting their paces across the bridge. Using the \u201cpace\u201d method, or even a more high-tech calculation employing a global positioning device that Criss supplied, the width of the river turned out to be only 1800 feet.<\/p>\n

The reasons behind the narrowing of the Mississippi River are of considerable interest and concern to Criss. \u201cThe Mississippi used to be a wide, braided river, with water running around islands and sand bars,\u201d he says. \u201cNow, it\u2019s like a thin string of spaghetti, and practically all of the islands and bars have been removed.\u201d<\/p>\n

<\/object><\/p>\n

The main culprits, says Criss, are the barge industry and the U.S. Army Corps of Engineers. He explains that, over the years, the Corps removed obstacles, such as islands, and put up thousands of wing dikes that narrow the channel. And it\u2019s all at the behest of the barge industry, says Criss. \u201cThe Army Corps of Engineers has become a \u2018pork\u2019 arm of Congress, and it\u2019s basically a facilitator for the barge industry,\u201d he says. \u201cThe industry wants bigger boats for more profitable operations, and bigger boats require a deeper, more predictable channel. These \u2018improvements\u2019 benefit the industry, but degrade the environment and worsen flooding.”<\/p>\n

But Criss\u2019 guided waterfront tour is not just a diatribe against the Army Corps of Engineers. He also offers intriguing historical lore that adds color to the story of the Mississippi River and its sojourn through St. Louis.<\/p>\n
