Feasibility Study: Souris River Basin

The Souris River in the North Dakota cities of Burlington, Minot, Logan, and Sawyer had a flood of record in 2011 with flows of 27,000 cubic feet per second. These flows devastated the communities and caused evacuations of more than 10,000 residents and millions of dollars in damage to private and public property. 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 Public Law 84-99 emergency levees, which were later incorporated into the Federal project.

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.

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.

Sandy Lake Dam Rehabilitation Project

Sandy Lake Dam is a significant hazard dam located on the Sandy River in Aitkin County, Minnesota, 1.25 miles upstream of the junction between the Sandy River and Mississippi River. The dam’s original purpose was to provide supplemental flow to the Mississippi River during periods of low river stages for navigation. Construction of the locks and dams downstream of Minneapolis in the 1930s reduced the need for upstream storage for navigation, and since then Sandy Lake Dam’s purpose has shifted to flood control, recreation, fish and wildlife conservation, and water supply.
