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

At 7:15 p.m. CDT on March 26, 2009, the river exceeded the 1997 crest of 39.57 feet (12.06 m) at Fargo, which was the previous second-highest crest. The projected crest was 24 feet (7.3 m) above flood stage and higher than the record-setting floods in 1997 and 1897.
At 2:30 a.m. CDT on March 27, the National Weather Service offices in Grand Forks issued a Flash Flood Warning for extreme east-central Cass County due to a levee breach in Fargo on Lindenwood Drive. With the river more than 6 meters (20 feet) above flood stage, there appeared to be a growing sense in Fargo that despite best efforts, it might not be possible to build dikes high enough to hold back the river. The Manitoba government upgraded the 2009 flood as the second highest to hit southern Manitoba over the last 150 years, just 60 centimeters (23.6 in) lower than the 1997 Flood of the Century. The highest level in 2009 was 6.9 meters (23 ft), and in 1997 it was 7.5 meters (25 ft). However, without flood control measures such as the Red River floodway, Portage Diversion and Shellmouth dam, the peak would have been 10.2 meters (33 ft), which is higher than the 1950 peak of 9.3 meters (31 ft) in Winnipeg. The Red River showed signs of receding April 23, however the Souris river was expected to crest towards the end of the month of April.
• Ice jams
On March 25, an ice jam formed north of Winnipeg, causing the municipalities of St. Andrews, St. Clements, East St. Paul and West St. Paul to declare a state of emergency. Flooding from the ice jam necessitated the evacuation of about thirty homes. While the jam was broken, it reformed near Lower Fort Garry, causing the water to rise 4.5 meters (14.7 feet) in 2 hours. On March 31, a state of emergency was declared for the city of Selkirk due to concerns over ice jams.
