    Dredge Goetz

    The U.S. Army Corps of Engineers, St. Paul District, uses the Dredge William L. Goetz to help maintain 850 miles of the Upper Mississippi River, 335 miles of the Illinois River and other inland rivers. The St. Paul District acquired it in the spring of 2005.
  • 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.
