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.
The study area is located in a rural setting in Polk County, Minnesota, 275 miles northwest of Minneapolis, Minnesota. The Sand Hill River basin is centrally located in the Red River Valley watershed. A major reach of the river downstream of Fertile, Minnesota, was the subject of a flood control project constructed by the Corps of Engineers from 1955 to 1958. It involved straightening the river and constructing several drop structures and served as a drainage improvement to local agriculture. Overall, more than 18 miles of the Sand Hill River was straightened or abandoned.
The study area is located in a rural setting in Wilkin County just to the east of Breckenridge, Minnesota, approximately 180 miles northwest of Minneapolis, Minnesota. The Otter Tail River is located in the upper portion of the Red River Valley watershed. A major reach of the river upstream of Breckenridge, Minnesota, was the subject of a flood control project constructed by the U.S. Army Corps of Engineers in the early 1950’s. It involved straightening, cleaning enlarging the river for drainage improvement to local agriculture. The overall length of the river in this reach was reduced from 18 miles to 11 miles as a result of the project. The straightened channel decreased channel length, increased channel grade, increased channel conveyance, increased bank erosion, and reduced the flood profiles in the lower Otter Tail River watershed.
Montevideo is located in Chippewa County in western Minnesota, approximately 130 miles west of St. Paul, Minnesota. The city is at the confluence of the Chippewa and Minnesota Rivers. The area is subject to flooding from both rivers. The three areas that are affected include the 1969 levee area, the Smith Addition and the U.S. Highway 212 area.
Wahpeton is in Richland County in eastern North Dakota, approximately 55 miles south of Fargo, North Dakota. The Red River of the North and the Bois de Sioux River border the city on the east. The confluence of the Otter Tail River with the Red River of the North is located at Wahpeton. The city of Breckenridge, Minnesota, lies east across the Red River of the North from Wahpeton.
Project locations: Orwell Lake on the Otter Tail River, approximately six miles southwest of Fergus Falls, Minnesota; Highway 75 Dam on the upper Minnesota River near Odessa, Minnesota; Lac qui Parle on the Minnesota River near Montevideo, Minnesota; Red Lake Dam located at the outlet of Lower Red Lake in the northeastern part of Clearwater County, Minnesota.
Breckenridge is in Wilkin County in western Minnesota, approximately 200 miles northwest of Minneapolis, Minnesota, and 55 miles south of Fargo, North Dakota. The Red River of the North and the Bois de Sioux River border the city on the west. The Otter Tail River flows from the east, bisecting the city. Wahpeton, North Dakota, is located to the west across the Red River from Breckenridge. The devastating flood of 1997 in the Red River basin generated a strong response at all levels of government to implement permanent flood risk management projects for urban communities along the Red River of the North.
Marsh Lake is on the Minnesota River between Swift and Lac qui Parle Counties near Appleton, Minnesota. The Marsh Lake Dam is owned and maintained by the U.S. Army Corps of Engineers as part of the Lac qui Parle Flood Risk Management project. The fixed-crest dam holds a conservation pool in the upper portion of the Lac qui Parle Reservoir. The Works Progress Administration constructed the dam and rerouted the Pomme de Terre River into the reservoir between 1936 and 1939.
The Minnesota River originates in southwestern Minnesota at the Minnesota-South Dakota border. It drains 16,770 square miles in Minnesota, South Dakota, North Dakota and Iowa. It flows 335 miles to join the Mississippi River at Mendota, Minnesota, just south of St. Paul and Minneapolis, Minnesota. The hydrology of the basin has been significantly altered, leading to increased erosion, impaired water quality, substantial sediment and nutrient loads, and degraded aquatic ecosystems in the Minnesota River, Mississippi River, and the Gulf of Mexico.
The Red River of the North rises in Lake Traverse near Wheaton, Minnesota and flows north towards Canada and ultimately to Lake Winnipeg. The Red River Basin Commission (RRBC) produced the Long Term Flood Study (LTFS) in 2011 after the 2009 event. Minnesota and North Dakota expressed the need for a coordinated, comprehensive, proactive plan that responds to and mitigates flooding and flood damages throughout the Red River Watershed.
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 Watershed was selected by the Minnesota Board of Water and Soil Resources as one of five pilot area for the One Watershed, One Plan (1W1P) program. The program allows counties to transition from county based water management planning to watershed based planning.
The Red River of the North basin covers 45,000 square miles and occupies substantial portions of North Dakota, northwestern Minnesota, southern Manitoba and a small portion of northeastern South Dakota. Land use in the basin is primarily agricultural, but several urban centers are located along the Red River main stem and tributaries. While extensive drainage systems have resulted in extremely rich agricultural areas, portions of the basin still support the ecologically abundant prairie-pothole region. Flooding is a major concern for residents in the basin; frequent floods have impacts on urban and rural infrastructure and agricultural production.
The Red River of the North basin is an international, multi-jurisdictional watershed of 45,000 square miles, with 80 percent of the basin lying in the United States and 20 percent in Manitoba, Canada. Eighteen Minnesota counties and 22 North Dakota counties lie wholly or partially in the basin. The river flows to the north, bringing water and nutrients to Lake Winnipeg in Manitoba. Flooding and loss of native habitat are significant issues in the Red River basin.
The Tribal Partnership Program is authorized by Section 203 of the Water Resources Development Act of 2000. The Tribal Partnership Program provides authority for the U.S. Army Corps of Engineers in cooperation with Indian nations to study and determine the feasibility of carrying out projects that will substantially benefit Indian nations. Activity may address (A) projects for flood damage reduction, environmental restoration and protection and preservation of cultural and natural resources; (B) watershed assessments and planning activities; and (C) such other projects as the Corps, in cooperation with Indian tribes and the heads of other federal agencies, determines to be appropriate.
