Great Lakes Dredge and Dock Company, LLC (GLDD) is working as a subcontractor with Western Contracting Corporation to provide fill for an emergency sand berm to close a levee breach at river mile 572 on the Missouri River.
GLDD’s Hydraulic Cutter Suction Dredge ‘Iowa’ is dredging approximately 350,000 cubic yards of river sands from a borrow source in the Missouri River and pumping along 7,000-ft of floating and shore pipeline to fill the 600-ft wide levee breach. An initial 75-ft wide berm closure was completed on June 20th and a second phase to widen the berm to 450-ft is underway.
According to the U.S. Army Corps of Engineers, Omaha District GLDD’s dredge cutter suction dredge Iowa completed an initial breach closure on a levee near Percival, Iowa yesterday. The Corps said this closure stops the inflows through this breach.
“Our USACE and Contractor team fought through tough challenges such as high water and floating debris in the river to close this critical breach and provide some protection to those affected, said Brendan Kight, PE, USACE Area Engineer. “This is a great milestone for the L575 levee system as we continue to repair the system and restore protection.”
