As a result of the damage, the government built the Red River Floodway, to divert flood waters from Winnipeg to more distant portions of the river. The project was completed in 1968 and has been used 20 times. From 1950 to about 1997, it was derogatorily referred to as "Duff's Ditch", after the premier ( Dufferin Roblin) that built the floodway. It is estimated to have prevented more than $100 billion (CAD) in cumulative flood damage. The Floodway was designated a National Historic Site of Canada in 2000, and is considered an outstanding engineering achievement both in terms of function and effects.
