Minnesota Congressional District 5 projects and studies

Continuing Authorities Program (CAP)

Under the Continuing Authorities Program (CAP), the U.S. Army Corps of Engineers is authorized to plan, design and construct certain types of water resource and ecosystem restoration projects without additional and specific congressional authorization. The purpose is to implement projects of limited scope and complexity. Each authority has specific guidelines and total program and per-project funding limits. Studies are cost-shared 50/50 during feasibility. Most projects are cost-shared 65 percent Federal and 35 percent non-Federal during implementation, unless otherwise noted.

Dam Bridge & Gate Painting – Lower St. Anthony Falls Through Lock and Dam 10

The St. Paul District operates and maintains 13 locks and dams from Upper St. Anthony Falls in downtown Minneapolis, Minnesota, to Lock and Dam 10 in Guttenberg, Iowa. Each lock and dam is a critical step in the "stairway of water" that makes navigation possible between Minneapolis and St. Louis, Missouri. These facilities are aging structures, with locks and dams 2 through 10 originally constructed in the 1930s. These sites include a dam bridge and varying numbers of dam gates. The moveable dam gates are one of the most critical system components because they control pool elevation for navigation, flood control and environmental purposes.

Hydropower, SAF Hydropower, Lower St. Anthony Falls Lock and Dam

The Federal Energy Regulatory Commission (FERC) issued license number 12451 on Feb. 21, 2006, granting the authority to SAF Hydropower, LLC, to construct and operate a hydropower facility on the Mississippi River at Lower St. Anthony Falls Lock and Dam in Minneapolis, Minnesota. The hydropower project includes an 8.98-megawatt generating system composed of a 16-unit turbine matrix, a control building, a transmission line and ancillary facilities. The total capacity of the plant is enough to provide power to 6,200 households.

Level of Service Reduction at the Twin Cities Locks and Dams

Constrained funding and the Nation’s fiscal deficit have led to reduced operations and maintenance funding within the Corps Inland Marine Transportation System (IMTS). When coupled with deteriorating infrastructure and increasing costs of operation, it became clear that the level of service the Corps has been providing at some locks and dams is not sustainable.

Minnesota River Basin Integrated Watershed Study

The Minnesota River had been recognized as highly degraded and a significant sediment source filling Lake Pepin on the Mississippi River and delivering nutrients to the Gulf of Mexico. The Minnesota River Basin Reconnaissance Study, Section 905(b) Analysis recommended an “Integrated watershed, water quality management, and ecosystem restoration analysis, leading to the development of a basin scale watershed management plan” for the Minnesota River Basin. The purpose of this Minnesota River Basin Interagency Study (MRBI Study) was to implement that recommendation by engaging agency partners and using advanced hydrologic modeling and environmental benefit analysis. The intent was to understand water, sediment, nitrogen and phosphorus transport across large landscapes to evaluate hydrologic, sediment and nutrient runoff response to historic, existing and probable future conditions.

Miscellaneous: Hydropower, Crown Hydro, Minneapolis, Minnesota

The Federal Energy Regulatory Commission (FERC) issued license 11175 to Crown Hydro, LLC, in 1999 which granted it the exclusive rights to develop a hydropower facility in the Mill Ruins Park area on the Mississippi River near Upper St. Anthony Falls Lock and Dam in Minneapolis, Minnesota. The Crown Hydro Project was originally proposed to be located in the Crown Roller Building and then, later, on Minneapolis park land. Crown Hydro was unable to secure the needed real estate agreements. Crown Hydro submitted a draft license amendment to FERC in April 30, 2015, which proposed locating the project on federal property at Upper St. Anthony Falls.

Mississippi River Lock and Dam 1, Ambursen Dam Downstream Repair

Lock and Dam 1 is located on the Minneapolis side of the Mississippi River. The purpose of this project is to re-establish armor downstream of the concrete apron. The existing rock protection consists of grouted derrick stone. This stone bedding has broken up and washed downstream, exposing bedding material and risking failure of the wooden piles and sheet pile located underneath the existing concrete apron.

Upper St. Anthony Falls Tainter Gate Rehabilitation

The Upper St. Anthony Falls Lock and Dam is part of the Inland Waterway Navigation System of the Upper Mississippi River Basin. The Tainter gate’s electrical control system has not been upgraded for many decades. Attempts to operate the gate have failed on various occasions and reliability is a concern. There is also question over the condition of the system’s hydraulics because the ram cylinder rooms and operating machinery rooms are constantly wet.
