  • Army Corps issues advisory regarding upcoming maintenance dredging along NJ Intracoastal Waterway

    The U.S. Army Corps of Engineers’ Philadelphia District has issued an advisory regarding upcoming maintenance dredging. The government owned and operated Dredge Merritt will be conducting maintenance dredging of portions of the federal channel of the New Jersey Intracoastal Waterway between markers 419 and 427, and between markers 388 and 399 near Stone Harbor, N.J. Work will take place between September 21 and 24 during daylight hours.

  • Dredging to Begin at Sandusky Harbor: Notice to All Boaters

    Dredging of the federal navigation channel in Sandusky Harbor by the U.S. Army Corps of Engineers, Buffalo District and its contractor, Michigan-based The King Co., Inc., will begin Sunday, Sept. 17. Recreational boaters who routinely use the channel should take caution and be aware of changes within the channel marked by buoys. Boaters are asked to go slow and stay away from marine equipment, stay clear of the contractor’s temporary pipeline, and stay out of the perimeter of the sediment placement area.

  • Evaluation of Structural and Operational Alternatives to Optimize the Distribution of Water and Sediment in the Passes of the Mississippi River

    Abstract: Mississippi River shoaling and dredging processes in the vicinity of Head of Passes and in Southwest Pass were investigated. Existing rates of deposition and dredging were determined using near-daily eHydro bathymetric surveys, National Dredging Quality Management dredge operating data, and geospatial processing steps developed for this study. These surveys provide a means to characterize the highly dynamic and variable sedimentation patterns observed in the navigation channel. The HEC-6T one-dimensional numerical sedimentation model was used to evaluate possible modifications to the distribution of water and sediment in the Mississippi River near Head of Passes in an attempt to reduce shoaling in the navigation channel. The model was used to evaluate the effects of partial closures of several distributaries downstream from Venice and to evaluate the effects of channel widening and channel deepening adjacent to the Hopper Dredge Disposal Area at Head of Passes. In this study, various structural alternatives were compared to a base test that represented existing conditions. Sedimentation and dredging effects were projected 50 years into the future.

  • U.S. Army Corps resumes Grand Haven dredging with additional E.coli testing

    The U.S. Army Corps of Engineers, Detroit District (USACE) will resume dredging in Grand Haven Harbor on Wednesday, July 12, with additional testing for E. Coli and safety measures. King Co. Inc., under an Army Corps contract, will dredge the remaining 35,000 of 141,000 cubic yards of sediment contracted to be removed from the outer harbor in Grand Haven to keep the commercial channel navigable throughout the remainder of the year. The Army Corps paused dredging at the location Friday, July 7, out of an abundance of caution after the Ottawa County Health Department issued a “no body contact” warning because of high concentrations of E. coli at North Park Beach in Ferrysburg. The remaining dredging will take about seven days to complete, weather dependent

  • Army Corps awards contract for Delaware River maintenance dredging

    The U.S. Army Corps of Engineers’ Philadelphia District awarded a contract to Seaward Marine of Norfolk, Va. for $12.9 million to conduct maintenance dredging of portions of the federal channel of the Delaware River between Philadelphia and Trenton.
