    Chippewa Diversion Repairs; Watson, Minnesota

    The Chippewa Diversion structure redirect flows from the Chippewa River to the Minnesota River to controlled via the Lac qui Parle embankment dam. The structure includes one Tainter gate and a low flow culvert with sluice gate. The site also includes a low channel. Maintenance is required one the Tainter gate, concrete gate structure, electrical components and low flow channel.

    Leech Lake Dam Preliminary Engineering Report (PER)

    Leech Lake Dam was originally constructed in the early 1880s under the Rivers and Harbors Act as a timber spillway with an earth and timber embankment. Over the history of the dam, the spillway was reconstructed with concrete piers and the downstream apron was replaced with concrete. The cofferdam breached during construction of the concrete aprons in 1957, resulting in loss of fourteen spillway bays which were replaced with earth embankment. Since then, the major components of the dam have remained relatively the same.
  • Navigation: Mississippi River Lock and Dam 7, Outdraft

    In 2017, a hydraulic study was launched to identify potential causes of the increased outdraft and to investigate and implement measures to alleviate the condition. Flow measurements collected over the last 30 years indicate a significant shift in flows just upstream of Lock and Dam 7 with nearly 20% more flow coming through the existing navigation channel which must then exit through the dam, exacerbating the outdraft condition.
  • Navigation: Pool 3 and Upper Pool 4 Dredged Material Management Plan – Dakota and Washington and Goodhue County, Minnesota, and Pierce County, Wisconsin

    The U.S. Army Corps of Engineers operates and maintains the Upper Mississippi River 9-Foot Channel Navigation Project, and one method the Corps uses to keep the channel the right size is dredging river soils or “material.” The purpose of the DMMP is to prepare a coordinated, long-term plan for managing dredged material in Pool 3 and Upper Pool 4. This plan was initiated due to needs for dredged material management upland placement sites.

    Navigation: Upper Pool 4 Channel Management Study Minnesota/Wisconsin

    The purpose of the study is to investigate if any action(s) would reduce the dredging frequency in the study area. Navigation in upper Pool 4 has been negatively affected by sedimentation in the navigation channel.

    Operations & Maintenance: Lake Traverse Repairs Modernization Project

    The St. Paul District staff has been conducting field investigations, developing hydrologic and hydraulic models and developing plans and specifications for the three sites as well as the water control manual update. The White Rock Dam modernization project will be ready for contract award in May 2025. The Reservation Dam and Browns Valley Dike work will be completed and awarded in 2025. The Water Control Manual update will be complete in 2025.

    Planning Assistance to States: Northern Red River Flood Study

    The North Dakota and Minnesota Departments of Transportation requested that a comprehensive water resource plan to identify and prioritize feasible alternatives to reduce the frequency and duration of road closures due to flooding of the Red River of the North.

    Planning Assistance to States: Thief River Falls

    The purpose of this potential project is to aid in providing technical assistance to gather baseline river sediment and morphology data. This data will potentially feed into future feasibility study and project addressing the city of Thief River Falls water quality.

    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.
  • Upper Mississippi River – Navigation and Ecosystem Sustainability Program Sny Magill Project

    This NESP study is a partnership with the National Park Service, U.S. Fish and Wildlife Service, Iowa Dept of Natural Resources, Wisconsin Dept of Natural Resources and the U.S. Army Corps of Engineers. The study will consider alternatives including riverbank stabilization and protection, floodplain restoration, closure or partial closure structures, and in-channel diversion structures.
  • Upper Mississippi River Restoration Program: Robinson Lake, Pool 4, Minnesota - Habitat Restoration

    The proposed project goal is to maintain, enhance, and create habitat suitable for native and desirable, aquatic and terrestrial plants and animals. The Robinson Lake area has lost bathymetric diversity, floodplain forest patch size, connectivity, and interior forest habitat over time. Island creation/enhancement and dredging would be the primary tools used to counter-act the losses. Increasing wild celery beds and perennial emergent vegetation would also be a goal within the lake to increase opportunities for migratory waterfowl. The project seeks to protect, enhance, restore, or create backwater and flowing channel habitats that provide diverse flow conditions and sediment dynamics that will benefit native fish (including migratory species) and mussel populations. The project seeks to protect and enhance diverse bottomland forest that will benefit migratory and resident birds and other species. The project also seeks to maintain or increase quantity and diversity of submerged, emergent, and rooted floating leaved vegetation.
