The U.S. Army Corps of Engineers, along with Roseau Mayor Jeffry Pelowski, U.S. Sen. Al Franken, U.S. Rep. Collin Peterson, state Sen. LeRoy Stumpf, state Rep. Dan Fabian, Minnesota Department of Natural Resources representative Kent Lokkesmoe and Mark Karl of Polaris Industries, dedicated the Roseau Flood Risk Management project August 18, 2015. The $44.6 million project includes a 4.5 mile diversion channel and 45 acres of recreation opportunities to include three birding sites, 9 miles of off-road vehicle trails, an ATV challenge course, 7 miles of multi-use trails and a trail head with parking and picnic area. The diversion channel was designed to divert floodwater around the city to reduce flood stages within the community.
Working up to seven days a week, excavators move 50,000 to 70,000 cubic yards of material a week as contractors work through the winter months to complete the Roseau, Minnesota, flood risk management project.

Location/DescriptionRoseau is located in the northwestern corner of Minnesota in Roseau County about 10 miles south of the Canadian border and about 65 miles east of the North Dakota border. Roseau’s population is about 2,800. It is home to Polaris Industries, Inc., which employs more than 2,000 people and along with agriculture, provides a solid economic base for the community. Roseau County has 16,000 residents.
Once the Roseau River flows out of its banks, it flows throughout most of the city. From June 9 to 11, 2002, intense rainfall over the river basin dumped an extraordinary amount of water into the area. This water quickly collected and drained into the Roseau River, overtopping the city's levee system and flooding most of the developed area. The flood damage was extensive, resulting in significant damage to downtown businesses and private residences.
After the 2002 floods, the city of Roseau and the Roseau River Watershed District asked the Corps to conduct a feasibility study for a flood control project in Roseau. In 2003, a likely Federal interest was determined and a feasibility study was completed in September 2006. The Chief of Engineers Report was signed in December 2006, with project design beginning in 2006. The project partnership agreement was signed June 15, 2009, initiating project construction.
Construction of the diversion channel is complete. The project consists of a 4.5-mile diversion channel, diversion inlet structure and river restriction structure located on the Roseau River. The project is operational and was dedicated August 2015. In January 2016, two reaches of the project were transitioned to the city of Roseau for long-term operation and maintenance. Minor miscellaneous activities were completed in 2016, and the final reach of the project was transitioned to the city in March 2017.
