Flood Risk Management: Devils Lake

To continue to meet the appropriate combination of levee and dam safety standards, it was necessary to raise the existing embankments protecting the city of Devils Lake, North Dakota and extend the embankments to high ground. Previously, the embankments had been constructed to an elevation of 1,460 feet.

Flood Risk Management: Wisconsin Silver Jackets Team

Silver Jackets teams are collaborative, state-led, interagency teams that are continuously working together to reduce flood risk at the state level. Through the Silver Jackets program, the U.S. Army Corps of Engineers, the Federal Emergency Management Agency, additional federal, state, and sometimes local and tribal agencies provide a unified approach to addressing a state’s flood risk priorities. Often, no single agency has the complete solution, but each may have one or more pieces to contribute. Silver Jackets team activities and projects occur throughout Wisconsin.

Mississippi River Lock and Dam 5A Embankment and Levee Certification

The Lock and Dam 5A embankment is located along the Mississippi River about 3.5 river miles above Winona, Minnesota, and about 3 river miles below Fountain City, Wis. FEMA is verifying that all levees recognized as providing protection from the base flood meet the requirements outlined in 44 CFR 65.10. This code requires that specific structural requirements must be certified by a registered professional engineer or a federal agency with responsibility for levee design. The city of Winona is performing this certification for the flood risk management project with the Corps providing an analysis of the Lock and Dam 5A embankment in support of that certification.

Red River of the North Basin-Wide Feasibility Study

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.

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 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. The Tainter gate’s electrical control system has not been upgraded for many decades. Attempts to operate the gate have failed on various occasions and reliability is a concern. There is also question over the condition of the system’s hydraulics because the ram cylinder rooms and operating machinery rooms are constantly wet.
