In Manitoba, the 2009 flood was the second worst on record since 1826. The Red River Floodway was not initially opened, due to the Red River being full of ice, which can lead to damage of the floodway and the flooding of Selkirk. The Red River Floodway was opened in early April once the ice jams cleared. Several towns and R.M.s declared a state of emergency due to the ice jams built up in places along the Red. Flooding in Manitoba was not expected until the second week of April. The CPR Line from Winnipeg to Emerson closed.
The floodway was opened around 1 p.m. on April 8 due to a crest expected to hit the city of Winnipeg. Highway 75, a major artery between Winnipeg and the U.S. border, was closed between April 7 and May 13. This closure cost Manitoba trucking companies thousands of dollars in additional travel costs and severely hurt the economy of the town of Morris.
