Feasibility Study: 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. The recovery efforts are still ongoing.

Upper Mississippi River Restoration Program: Conway Lake, Lansing, Iowa

Dissolved oxygen is essential for a healthy fisheries habitat. Dissolved oxygen depletion is a problem in the study area in summer and in winter due to a variety of reasons. Conway Lake is relatively shallow with abundant aquatic vegetation. During the winter, excessive water enters Phillipi Lake through openings that are eroding, creating unsuitable habitat conditions for overwintering backwater fish. Shore Slough has less than optimal fish habitat conditions as a result of sedimentation and the high flows from Phillipi Lake.

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.
