  • Pokegama Dam Slurry Trench Project, Grand Rapids, Minn.

    Pokegama Dam was constructed in 1884. The main embankment was constructed with a pervious, rock and clay-filled timber structure core and covered with sandy material. In 1941, a sheetpile wall was installed upstream of the timber core to minimize unwanted seepage (flow) through the embankment. The existing sheetpile wall has been effective at controlling seepage, but its overall condition is currently in question. Without an effective seepage barrier, the water levels could rise throughout the embankment causing downstream slope instability, which would threaten the integrity of the dam.

  • 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: 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: Harpers Slough, Pool 9, Iowa Habitat Restoration

    Harpers Slough area is a 3,510-acre backwater located primarily on the Iowa side of the Mississippi River in Pool 9, about 3 miles upstream of Lock and Dam 9. The site is in the Upper Mississippi River National Wildlife and Fish Refuge. The purpose is to assess the extent of damage of islands and habitat and determine repairs necessary for the Harpers Slough Project in Pool 9. Construction was completed in 2017; however, two consecutive years of high water (including record levels in 2019) prevented plantings from becoming established and caused significant breaches in three islands. Island loss led to material deposition in the backwaters, resulting in less productive habitat for fish and wildlife and the project not achieving the benefits originally anticipated.
  • Upper Mississippi River Restoration Program: Lake Winneshiek

    Lake Winneshiek is a 6,000 acre backwater lake on the Wisconsin side of the Mississippi River navigation channel in lower Pool 9 about 4 miles downstream from Lansing, Iowa. The proposed project would create two islands, each about 8,000 feet long, in the center of Lake Winneshiek to reduce wave action in this large, open water area. If suitable construction material can be found in the backwater area, dredging would provide up to 20 acres of additional deepwater habitat.
  • Upper Mississippi River Restoration Program: Lower Pool 10 Islands, Guttenberg, Iowa Habitat Restoration

    This program, authorized by Congress in 1986, emphasizes habitat rehabilitation and enhancement projects (HREPs) and long-term resource monitoring. The HREP component includes dredging backwater areas and channels, constructing dikes, creating and stabilizing islands, controlling side channel flows and water levels, and creating floodplain forest habitat.
  • 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.
  • 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.
