Corps Awards Contract For Dredge Project

The St. Paul (Minn.) Engineer District awarded a $7.475 million contract September 24, 2018, to Dubuque Barge & Fleeting Services Company, Dubuque, Iowa, to carry-out a Corps Island dredged material unloading project.

The project involves unloading approximately 500,000 cubic yards of dredged material from Corps Island, located in Pool 3 of the Mississippi River, near Diamond Bluff, Wis. The contractor is removing the material by mechanical and/or hydraulic means.

Corps Island was endorsed for use as a dredged material placement site by the River Resources Forum in December 1995, as recommended in the 1995 Lower Pool 3 reconnaissance report prepared by the Corps of Engineers. The report recommends that channel maintenance material be placed on Corps Island until site capacity is reached—approximately 500,000 cubic yards—then transferred (unloaded) to an upland placement site.

Work is anticipated to begin in the spring of 2019 and be completed by December 2019.
