  • USACE shares update on Manasquan Inlet

    The U.S. Army Corps of Engineers (USACE) Philadelphia District shared an update regarding navigation at the Manasquan Inlet in Ocean County, N.J. USACE is aware of the shoaling within the Manasquan Inlet inside of the south jetty. Currently, USACE is working to obtain hydrographic surveys of the current inlet conditions. Once completed, this information will be posted online for mariners to access and shared with the U.S. Coast Guard. The USACE Dredge MURDEN is currently scheduled to conduct dredging operations within the inlet later this month and may conduct some operations early this week depending on weather and sea conditions.
  • Corps of Engineers identifies Little Lake Harbor as critical need for dredging

    SAULT STE. MARIE, Mich. – The U.S. Army Corps of Engineers, Detroit District identifies Little Lake Harbor, located near Newberry, Michigan, as a critical need for dredging due to significant shoaling and shoreline flooding. “Little Lake Harbor is a shallow draft harbor that serves as an important Harbor of Refuge and supports Tribal fishing,” LeighAnn Ryckeghem, Sault Sainte Marie Project Office, Operations Manager said. “Due to severe shoaling, the harbor has not been functional in some time. The Corps of Engineers issued a Notice to Navigation Interests in August of 2021 to use extreme caution when attempting use.” The harbor conditions are surveyed annually and the harbor requires annual maintenance dredging. The harbor was last dredged in 2018 with approximately 53,000 cubic yards of material removed. The Detroit District has identified the funding need for both maintenance dredging and structure maintenance at Little Lake Harbor since 2020. However, needs for maintenance of navigation projects throughout the country outpace available funds.
  • 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.
  • U.S. Army Engineer Research and Development Center assists Kansas City Corps with hydrodynamic dredge

    In a demonstration of collaboration and innovation, the U.S. Army Engineer Research and Development Center deployed an experimental asset and team of experts to the Missouri River in the Kansas City District, U.S. Army Corps of Engineers, to assist in dredging shallow areas called shoals in the navigation river channel.
  • PUBLICATION NOTICE: Investigation of Shoaling in the Federal Navigation Channel, Waukegan Harbor, Illinois

    Abstract: Persistent and excessive shoaling occurs in the Outer Harbor and Approach Channel of the Waukegan Harbor, Illinois. This report describes a numerical modeling study performed for the US Army Corps of Engineers, Chicago District, to evaluate the existing harbor and 11 structural alternatives for three crest elevations. This report provides details of numerical modeling study, analysis of field data, and estimates of shoaling. The focus of the study is the investigation of a variety of structural solutions intercepting and/or diverting sediments to reduce shoaling in the navigation channel. These include breakwaters, groins, spurs, and structural extensions with varying length and crest elevation connecting to the north beach and existing north breakwater. Estimates of both shoaling volume and height are developed with and without project using an integrated wave-flow-sediment transport numerical modeling approach. Quantitative reduction estimates are provided for each structural alternative investigated.
  • Dredging to start in Norfolk Harbor inner channels

    NORFOLK, Va. – The U.S. Army Corps of Engineers and Cottrell Contracting are set to begin dredging the Norfolk Harbor Inner Channel and channel to Newport News on Saturday.
  • Norfolk District begins James River dredging

    NORFOLK, Va. – James River Federal Navigation Project engineers are ramping up efforts to minimize shoaling effects and improve safe navigation along Central Virginia’s winding watershed. Norfolk District, U.S. Army Corps of Engineers and Cottrell Contracting Corp. commenced maintenance dredging Sunday in the 7.6-mile Dancing Point-Swann Point channel.
  • Army Corps, State to host public meeting on Ocean City inlet projects

    The U.S. Army Corps of Engineers, in coordination with the Maryland Department of Natural Resources and Worcester County, is hosting a public meeting May 30 at the Worcester County Library – Berlin Branch (13 Harrison Ave. in Berlin) from 6:30 – 8:30 p.m. to discuss two concurrent efforts: a project to address sediment accumulation in the Ocean City Inlet, as well as a study on the scour hole near Homer Gudelsky Park.
  • Norfolk District to begin Dismal Swamp Canal dredging

    CHESAPEAKE, Va. – The U.S. Army Corps of Engineers is set to begin Dismal Swamp Canal dredging early next week – roughly a year ahead of schedule due to lingering impacts from Hurricane Matthew in 2016. The maintenance work should be completed by April.
  • Army Corps kicks off inlet navigation improvement project with State of Maryland, Worcester County

    The U.S. Army Corps of Engineers, Maryland Department of Natural Resources, and Worcester County signed a Project Partnership Agreement Feb. 14 to start work on a navigation improvement project to address sediment accumulation, or shoaling, within the Ocean City Inlet.
