  • Souris Court Levee Repair, Minot, ND

    The Souris River flows from Saskatchewan, Canada into North Dakota and then back into Canada. Minot is a city located in north central North Dakota with a population of approximately 46,000 residents. Above normal precipitation during the summer and fall of 2010 left much of the eastern portion of Saskatchewan saturated. The winter of 2010 and 2011 then saw snowfall significantly above normal throughout the basin. The Souris River in the Minot area started to rise in April 2011 and continued to rise throughout May 2011.
  • Souris River Basin, North Dakota

    In the mid-1970s, a series of major flood events occurred. To protect the communities, the U.S. Army Corps of Engineers constructed a series of emergency levees under Public Law 84‒99. These levees were later incorporated into the federal project. Since then, the emergency levees have undergone limited maintenance and experienced structural encroachments; however, these levees remain the primary line of defense for major flood events. While the emergency levees have provided some protection against major flood events, a permanent solution is needed to reduce the flood risk to these critical North Dakota communities. The Souris River in the North Dakota cities of Burlington, Minot, Logan, and Sawyer had a flood of record in 2011 with flows of 27,400 cubic feet per second. These flows devastated the communities and caused evacuations of more than 11,000 residents and approximately $1 billion in damage to private and public property.

  • 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.
