  • St. Louis District, U. S. Army Corps of Engineers, Dredge Potter underway for another dredging season

    The Dredge Potter, owned and operated by the U. S. Army Corps of Engineers, St. Louis District, is getting underway today for the 2024 dredging season ensuring safe navigation for commercial vessels on the Illinois and Mississippi Rivers. In 2023, drought conditions required the crew and then 92-year-old vessel to move 6.3 million cubic yards of sand, silt, and clay from the river bottom at 31 different locations.
  • Corps of Engineers begins dredging operations near Brownsville, Minnesota

    The U.S. Army Corps of Engineers, St. Paul District, is conducting dredging operations at their Above Brownsville Placement site, also known as “Crater Island,” within Pool 8, of the Mississippi River, near Brownsville, Minnesota.
  • USACE marks completion of the Indiana Harbor Confined Disposal Facility Dike Raise Construction Project

    Today, the U.S. Army Corps of Engineers (USACE) Chicago District, Rep. Frank J. Mrvan (IN-1), and Fernando Trevino, Executive Director of the East Chicago Waterways Management District, marked the completion of the Dike Raise construction project at the Indiana Harbor Confined Disposal Facility.
  • Corps of Engineers begins dredging operations in Saugatuck

    The U.S. Army Corps of Engineers, Detroit District, will begin dredging 68,000 cubic yards of sediment from Saugatuck Harbor, Michigan, next week to ensure safe navigation between Lake Michigan and the Kalamazoo River. The two-mile federal channel in Saugatuck is a popular recreational destination and harbor of refuge. The King Company, of Holland, is contracted to complete the work for $341,000, after completing dredging in Muskegon under the same awarded contract totaling $1.4 million.
  • Site Selection and Conceptual Designs for Beneficial Use of Dredged Material Sites for Habitat Creation in the Lower Columbia River

    Abstract: Channel maintenance in most major rivers throughout the United States requires ongoing dredging to maintain navigability. The US Army Corps of Engineers explores several options for placement based on sediment characteristics, material quantity, cost, operational constraints, and minimization of potential adverse effects to existing resources and habitat. It is a priority to beneficially reuse dredged sediments to create habitat and retain sediments within the river system whenever possible. Nonetheless, there can be discrepancies among state and federal resource agencies, landowners, tribes, and various other stakeholders about what constitutes a benefit and how those benefits are ultimately weighed against short- and long-term tradeoffs. This work leveraged prior Regional Sediment Management efforts building consensus among stakeholders on a suite of viable strategies for in-water placement in the lower Columbia River. The goal was to identify suitable locations for applying the various strategies to maximize habitat benefits and minimize potential adverse effects. A multistep site-selection matrix was developed with criteria accounting for existing site conditions, overall placement capacity, tradeoffs, long-term maintenance, cost, stakeholder concerns, and landscape principles in the context of other habitat restoration projects implemented in the lower river. Three highly ranked sites were selected for conceptual design and exemplify results of collaborative beneficial use implementation.
  • Rolling Prairie, Minnesota, Beneficial Use Area: A 100-Year Plan for Multiuse Land Management and Restoration Using Dredged Sediment

    Purpose: Inland waterway dredged sediment management is challenged by a lack of capacity in existing dredged material confined disposal facilities (CDFs) and a lack of available land to place sediment near frequently dredged navigation channels. Navigation operation and maintenance (O&M) dredging, material management, and coordination costs are increasing, and alternative long-term solutions are required. In response, the US Army Corps of Engineers (USACE), St. Paul District has addressed the challenge by investigating regional sediment management and beneficial use of dredged material when updating navigation pool–specific dredged material management plans (DMMP). The recently completed Pool 5 DMMP planning identified a 950 acre (384 ha)[1] placement site consisting of several land parcels available from willing sellers that will accommodate a “100-year plan” for dredged material management (USACE 2019). This technical note describes the multiple-use site plan that creates sand prairie and wetland habitat, provides public access to sand stockpiles, and implements agriculture studies with the University of Minnesota to evaluate the benefits of dredged material (i.e., sand) amendments in alluvial cropland soils, which has not been widely investigated. The Rolling Prairie site will demonstrate benefits of “distributed DMMPs” in which thin-layer placement on agricultural land near dredging locations can supplement traditional disposal methods. It also shows the advantage of having a large placement site to achieve multiple objectives.
  • Jacksonville District hosts Atlantic Intracoastal Waterway boat tour

    Jacksonville, Fla. -- (May 1, 2024) The U.S. Army Corps of Engineers Jacksonville District, partnered with the Florida Inland Navigation District, U.S. Coast Guard, and local stakeholders, on the U.S. Army Corps survey vessel, Florida II to conduct inspections along segments of the Atlantic Intracoastal Waterways. While unconventional, the ship provided an invaluable setting for decision-makers to witness firsthand the environmental areas under discussion and foster relationships among stakeholders.
  • USACE & FIND host the Atlantic Intracoastal Waterway boat tour

    On May 1, 2024, members of the U.S. Army Corps of Engineers (USACE) Jacksonville District, joined by partners from the Florida Inland Navigation District (FIND), U.S. Coast Guard, and various stakeholders, embarked on the vessel named Florida II to conduct inspections along segments of the Atlantic Intracoastal Waterways (IWW). While unconventional, the ship provided an invaluable setting for decision-makers to witness firsthand the environmental areas under discussion and foster relationships among stakeholders.
