  • Dredging project to cause temporary river closure near Keithsburg, Illinois

    Beginning today, the U.S. Army Corps of Engineers, Rock Island District, will temporarily close the main channel of the Mississippi River at river mile 425.7 in Pool 18 near Keithsburg, Illinois, to move dredged material from Willow Bar Island to the Iowa shore. The closure is anticipated to last three weeks and will impact navigation.

  • LA District marks completion of Newport Bay Harbor jetty repairs, dredging slated to finish Sept. 10

    After the placement of 4,500 tons of stone and 150 cubic yards of concrete, the U.S. Army Corps of Engineers Los Angeles District marked the completion of repairs to the east jetty at Newport Bay Harbor, with the area reopening to the public Aug. 25.

  • Corps of Engineers set to dredge Mississippi River near Winona, MN

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is planning to dredge the Mississippi River near Winona, Minnesota, at the end of the month.

  • Corps advises mariners it will begin dredging Intracoastal Waterway, Palm Valley North Reaches, in St. Johns County

    The Jacksonville District, U.S. Army Corps of Engineers, will begin dredging sections of the Intracoastal Waterway (IWW) in St. Johns County, Florida, within the Palm Valley North Reach beginning in the October 2021 timeframe and finishing in May 2022.

  • From the Wicomico River to Deal Island

    The U.S. Army Corps of Engineers, Baltimore District, and several local, state and federal agencies have been partnering up to find a new placement site on the eastern shore of Maryland for material dredged from the Wicomico River. After extensive research and evaluation, USACE and partners agreed on the Deal Island Wildlife Management Area in Somerset County to hold the material and also provide beneficial long-term environmental benefits.

  • ERDC researcher’s detective work helps ship channel improvement project stay on track

    A construction effort as massive as the Houston Ship Channel Expansion Improvement Project — designed to accommodate the wider and deeper ships now carrying goods back and forth between Asia and the U.S. — has many regulatory requirements that need to be met.

  • Army Corps, State to host public meeting on Ocean City Inlet projects

    The U.S. Army Corps of Engineers, Baltimore District (USACE), in coordination with the Maryland Department of Natural Resources (DNR) and Worcester County, is hosting a hybrid public meeting Aug. 17, 2021, at the Worcester County Library – Berlin Branch at 13 Harrison Ave., from 7 – 8:30 p.m. This public meeting provides an opportunity to discuss two concurrent efforts: a navigation improvement project to address sediment accumulation in the Ocean City Inlet and a study on the scour hole near Homer Gudelsky Park.

  • Corps plans Depoe Bay dredging, after environmental assessment

    The U.S. Army Corps of Engineers will begin dredging Depoe Bay, Ore. to remove 2,000 cubic yards of material between September 13 and the end of the month. The work will take place for seven to 14 days and is an effort, with the City of Depoe Bay, to clean out the sediment catch basin.

  • An Assessment of Long-Term, Multipurpose Ecosystem Functions and Engineering Benefits Derived from Historical Dredged Sediment Beneficial Use Projects

    Abstract: The beneficial use of dredged materials improves environmental outcomes while maximizing navigation benefits and minimizing costs, in accordance with the principles of the Engineering With Nature® (EWN) initiative. Yet, few studies document the long-term benefits of innovative dredged material management strategies or conduct comprehensive life-cycle analysis because of a combination of (1) short monitoring time frames and (2) the paucity of constructed projects that have reached ecological maturity. In response, we conducted an ecological functional and engineering benefit assessment of six historic (>40 years old) dredged material–supported habitat improvement projects where initial postconstruction beneficial use monitoring data was available. Conditions at natural reference locations were also documented to facilitate a comparison between natural and engineered landscape features. Results indicate the projects examined provide valuable habitat for a variety of species in addition to yielding a number of engineering (for example, shoreline protection) and other (for example, carbon storage) benefits. Our findings also suggest establishment of ecological success criteria should not overemphasize replicating reference conditions but remain focused on achieving specific ecological functions (that is, habitat and biogeochemical cycling) and engineering benefits (that is, storm surge reduction, navigation channel maintenance) achievable through project design and operational management.

  • Corps set to move dredged material, urges caution near work site

    The U.S. Army Corps of Engineers, St. Paul District, is scheduled to begin moving approximately 50,000 cubic yards of river sand, or dredged material, from the Dakota Island Placement Site, near Dakota, Minnesota, to the Trempealeau, Wisconsin, Placement Site, which is about 8 miles away.
