Flooding likely to impact river navigation

An Army Corps of Engineers official says the flooding in Minnesota, Iowa, and Wisconsin will likely create some navigation problems on the upper Mississippi River.

Alan Marshall with the Rock Island District office tells Brownfield flooding in Minnesota and Wisconsin is where most of their flow is coming from and all but two recreational areas on the Mississippi River are already closed.  He expects there will be a few lock and dam closures stopping the flow of cargo in the next week. “Locks 12, 16, and 17 are currently likely to close, not for sure, but based on the forecast. Each lock has a certain river level that if it reaches it, they have to close it for safe operations of the lock.”

Locks 12, 16, and 17 are in Bellevue, Iowa, Muscatine, Iowa, and New Boston, Illinois, respectively.

Janet Meredith with the St. Louis District office tells Brownfield the massive flooding now in Minnesota and northwestern Iowa will not make Mississippi River navigation worse, and that water will probably make it to the St. Louis harbor by the weekend. “This Saturday, it will come up a foot and then we’ll see. We’ve got a long way before we get to flood stage.”

The Rock Island District manages the Mississippi River and tributaries between the confluence of the Wisconsin River and Hannibal, Missouri.  The St. Louis District manages the river downstream to the confluence of the Ohio River.
