2011 Red River Flood, North Dakota, Minnesota, United States

Volunteers continued preparing sandbags, with 560,000 bags filled by late March 22, out of an expected 1.5 million to 2 million needed. By March 24, residents in Fargo-Moorhead had filled over 1 million sandbags and were attempting to fill a total of 2 million by the 26th. A levee in Georgetown, Minnesota was raised another two feet, and emergency dikes were being built in Fargo, Moorhead, Harwood, Grafton and Richland County. The predicted flood crest was raised again on March 26, changed to between 41 feet (12 m) and 42 feet (13 m) by March 28, with a possibility of 43 feet (13 m).
In addition to the sandbags, the construction of the dikes protecting the city required large amounts of clay. Clay had been brought from several places in and around the city, including the soccer field at Centennial Elementary School and around Discovery Middle School.
• Wahpeton-Breckenridge
Elsewhere along the river, early predictions for the Wahpeton-Breckenridge area saw a predicted level of at least 16 feet (4.9 m). By March 24, the National Weather Service predicted the crest in Wahpeton and Breckenridge not to top 18 feet (5.5 m), below the cities' levees.
