    Beneficial Use of Dredged Material: Section 1122, Upper Pool 4 – Lake Pepin, Bay City, Wisconsin

    This project utilizes dredged material generated from navigation channel to protect and restore backwater habitat; this is a win-win project for the U.S. Army Corps of Engineers, our partner agencies, and the environment. The Wisconsin Department of Natural Resources is the non-federal sponsor.

  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program (NESP) Systemic Mitigation Island 4 Project

    Sedimentation and sediment resuspension caused a loss in water depth diversity of the backwater lakes and isolated wetlands above Lake Pepin as well as a loss in aquatic vegetation. Concerns over habitat deficiencies in Upper Pool 4 include reduced habitat diversity and quality, lack of aquatic vegetation and invertebrates, and reduced abundance of fish and wildlife. The project includes construction of a peninsula to improve habitat conditions by reducing wind, waves, and redirecting sediment inflows. It also includes overwintering dredging to support a deep water habitat for fish and bank and shoreline stabilization to reduce inflows and erosion during high flow events.

  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program (NESP) Wacouta Bay Project

    This is a NESP study partnership with the Wisconsin Department of Natural Resources (WIDNR), Minnesota Department of Natural Resources and the U.S. Army Corps of Engineers. The study will consider alternatives including island building and enhancement, forest enhancement and creation, backwater restoration and dredging, island and shoreline protection and beneficial use of dredged material.
