A Winter to Remember: Corps of Engineers continues annual winter maintenance fight to preserve aging infrastructure

The American Society of Civil Engineers 2021 infrastructure report card released in March was less than perfect for the nation’s inland navigation system. According to the report, they gave the Inland waterway infrastructure a D+. The ASCE report said the infrastructure "includes locks and dams as well as navigation channels” but added that shipping delays cost up to $739 per hour for an average tow within the United States.

Moving sand isn’t just for kids

Navigation on the Upper Mississippi River this year has been anything but normal. Historic flooding plagued the region for much of the spring and early summer. The floods brought historic high water and a significant increase in the amount of sediment. The high water has since receded leaving sediment as the sole souvenir of the 2019 flood.

Dredge W.A. Thompson and early dredging

In 1930 the 9-foot draft channel was legislated by Congress to increase commerce on the river. The U.S. Army Corps of Engineers began construction of the series of 29 locks and dams between St. Louis and Minneapolis, creating a stairway of water for river traffic. Since the river is constantly shifting its load of sand and sediment and tributaries along the way contribute more it is necessary to remove the material from the bottom of the channel to prevent a closure to navigation. This process of underwater excavation is called dredging.
