Lac qui Parle Dam Emergency Spillway; Watson, Minnesota

The Lac qui Parle dike and emergency spillway is designed to retain the Lac qui Parle Reservoir during times of flood but is designed for overtopping during extreme events. The overtop elevation of the spillway is 940.75 feet. The Lac qui Parle Dam is located on the upper Minnesota River 30 miles east of the South Dakota border. The dam is about seven river miles upstream of Montevideo, Minnesota. The dike and emergency spillway is adjacent to and west of the dam between the dam and County Hwy 75. The damaged area of the spillway extends approximately 2,500 feet from the dam.

Mississippi River Locks and Dams 2–10 Miter Gates Replacement

Locks and Dams (LD) 2 through 10 have used the same miter gates since their construction in the 1930s. Over time, the gates have been damaged and distressed, which has led to serviceability and safety issues. This project will replace the gates and the anchorages system, increasing navigational longevity and operational readiness while decreasing repair costs and downtime due to maintenance or failure. Upper Mississippi Locks and Dams 2 through 10.

Mississippi River Locks and Dams 2–10 Non-Structural Embankment Repair

The non-structural embankment repair projects at Locks and Dams (LD) 2 through 10 will address restoring embankments to meet current design standards. Most dam embankments are currently protected from the erosive forces of water by a layer of riprap placed along the embankment’s length. When the riprap eventually erodes, the embankment itself will erode if more protection is not added. Upper Mississippi Locks and Dams 2 through 10.

National Loon Center Facility, Public Docks and Shoreline Protection Project, Crosslake, MN: Review Outgrant Request (REC, ENS)

The National Loon Center Foundation, a 501(c)(3) tax-exempt non-profit organization, is proposing the construction of a 15,000 square-foot National Loon Center Facility as well as 3,100 linear feet of shoreline protection efforts at the Cross Lake Recreation Area. The center will include a welcoming entrance and lobby area, interpretive displays, an aquarium, indoor/outdoor classrooms, laboratory, gift shop, conference rooms and office space, and a kitchen designed for concessions and large group events. The architectural design of the facility will conform to a “Northwoods” theme with fountains and a fireplace. Loon focused learning opportunities will extend beyond the interpretive exhibits and into the bay and throughout a trail system along the shoreline. An interpretive trail, multi-slip docks, and shoreline protection measures will provide visitors with a unique and educational experience.

Navigation and Ecosystem Sustainability Program (NESP)

The Navigation and Ecosystem Sustainability Program (NESP), seeks to provide a safe, reliable, cost effective and environment sustainable waterborne navigation system by implementing switchboats at five locks, constructing mooring cells and seven new 1,200 foot locks. NESP will restore the aquatic and terrestrial habitat to a more natural condition on more than 100,000 acres throughout the system through a wide variety of ecosystem projects.

Planning Assistance to States: Red River Basin Comprehensive Study

The purpose of this study is to investigate the effectiveness of various flood risk reduction measures basin-wide to reduce main stem peak flows by 20% for the larger rare events such as the 0.5 (200-year) and 0.2% (500-year) chance of exceedance floods.

Planning Assistance to States: Yellow Medicine River and Minnesota River Watersheds, Minnesota

The Yellow Medicine River is a major tributary to the Minnesota River located in southwestern Minnesota. The study area for this project includes approximately 685 square miles of mostly agricultural lands across five counties. The Yellow Medicine River and Minnesota River wetland project addresses three high priority concerns: (1) mitigate altered hydrology and minimize flooding; (2) minimize transport of excess nutrients, sediment and bacteria; and (3) preserve groundwater quantity and quality.

Project Alteration Reviews: Section 408

Section 14 of the Rivers and Harbors Act of 1899 authorizes the Secretary of the Army to grant permission for alterations to existing U.S. Army Corps of Engineers projects under certain circumstances. The authority is codified in 33 U.S.C. Section 408. Authority to approve alterations has been delegated to the district commander in most cases, although certain alterations require approval from the director of Civil Works at the Corps’ Headquarters (HQUSACE). The Corps may grant permission for the alteration or permanent occupation or use of any of its public works when, in the Corps’ judgment, the occupation or use will not be injurious to the public interest and will not impair the usefulness of the federal works.

Upper Mississippi River Restoration Program: Reno Bottoms, Pool 9, Upper Mississippi River

The primary objective of this project is to protect, restore, or create resilient and diverse bottomland forests. The quality and extent of the unique forest and aquatic habitat in the Reno Bottoms project area has been declining over the past several decades. Human caused changes in hydrology, land use, and climate have increased water levels within the project area. Without action, the project area will continue to degrade. The quality of forest and aquatic habitat will decrease. Invasive grasses would expand into forests, limiting opportunities for smaller trees to grow and reducing habitat value. Additional loss of wetland habitat would adversely affect migrating waterbirds and songbirds who require the floodplain forest to stop and rest.

Upper Mississippi River Restoration Project Big Lake, Pool 4, Wisconsin

As with the much of the upper Mississippi River, sedimentation of backwater areas is an ongoing issue. The project area is greatly influenced by the input of sand from the Chippewa River that enters Pool 4 at about river mile 764. Other potential sources of sand are the historic channel maintenance dredging side-cast islands and the four active temporary placement sites within the study area. Big Lake has lost much of its island complex and bottomland forest to wind and wave erosion. The barrier islands between the lake and Catfish Slough have been degraded and/or eliminated over the past several years.
