The project is the routine maintenance, including painting and repair of the dam gates. Phase 1 consisted of report development, including alternatives and life cycle costs. Phase 2 of the project analyzed the alternatives, and decided upon an Indefinite Delivery – Indefinite Quantity (IDIQ) acquisition strategy with maintenance performed on site.
Granting licensing of a privately-owned hydropower project on federal property. The project is proposed to be located at Upper St. Anthony Falls lock and dam, in Minneapolis, Minnesota.
This dam modification and equipment refurbishment project replaces nine sluice gates and associated operating equipment and installs a permanent stop log dewatering system to provide a dry environment to allow for sluice gate and concrete inspection, maintenance, repair and modifications without impeding all flow through the dam. 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, and 300 river miles upstream of Minneapolis, Minnesota.
Embankment rehabilitation will address restoring embankments to meet current design standards. Overtopping protection adjacent to concrete structures is the first priority for design and construction. No increase in the height of the embankments is planned. Upper Mississippi Locks and Dams 2 through 10.
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.
The tow rail system is integral to the operation of each of the Mississippi River Locks and Dams 2 through 10. It is attached to the top of the lock guidewall and helps guide tows through the lock chamber. Each system is comprised of an operating unit, rail and traveling kevel or “mule.” The Locks and Dams 2 through 10 tow rail systems have been deteriorating over the past several years, requiring rehabilitation of these systems.
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.
The purpose of the Dredged Material Management Plan (DMMP) is to prepare a coordinated long-term plan for managing dredged material from Pool 6. The Pool 6 DMMP study area is located between Lock and Dam 5A at river mile 728.5 and Lock and Dam 6 at river mile 714.1. The study area borders the city of Winona, Minnesota, at the upstream end and extends downstream of the village of Trempealeau, Wisconsin.
The Tribal Partnership Program (TPP) provides authority for the U.S. Army Corps of Engineers to utilize TPP to perform water-related planning activities and activities related to the study, design and construction of water resources development projects located primarily on tribal lands that substantially benefit federally-recognized tribes. To start the process, a tribe submits a study request to the U.S. Army Corps of Engineers. The Corps evaluates the request, and if viable, the Corps works with the tribe to determine a scope of work and enters into a feasibility cost sharing agreement (FCSA). Following the execution of the FCSA, the Corps seeks federal funding for the study.
Navigation and Ecosystem Sustainability Program (NESP) is a long-term program of ecosystem restoration and navigation improvements for the Upper Mississippi River System (UMRS). NESP will improve system capacity and reduce commercial traffic delays through construction of seven new 1,200-foot locks, mooring cells, and switchboat implementation.
The U.S. Army Corps of Engineers, St. Paul District is responsible for maintaining 244 miles of the Upper Mississippi River 9-foot channel navigation system from Minneapolis, Minnesota, to Guttenberg, Iowa. The Upper Mississippi River 9-Foot Channel Navigation Project is located in or contiguous to Minnesota, Wisconsin, and Iowa. The navigation project within the St. Paul District includes 13 locks and dams that are operated and maintained by the Corps. In addition to the locks and dams, the project includes channel maintenance, recreation and natural resource activities.
The U.S. Army Corps of Engineers is responsible for maintaining a 9-foot navigation channel as an important component to the inland navigation system. The St. Paul District (MVP) is responsible for maintaining 244 miles of the Upper Mississippi River 9-Foot Channel Navigation Project from the head of navigation at Minneapolis, Minnesota, to Guttenberg, Iowa. The navigation project also includes the lower navigable portions of the Minnesota, St. Croix, and Black Rivers.
