Southern Manitoba has extensive flood control measures in place, particularly in the Red River Valley, from Winnipeg, south to the US border. Flood controls were built after the devastating flood of 1950, which flooded the Red River Valley and the City of Winnipeg. Construction of the Red River Floodway was completed in 1968. Additional flood control improvements, including an expansion of the floodway, were made after the Flood of the Century in 1997. This flood was substantially larger than the 1950 flood, but resulted in far less property damage because of the flood control measures in place. There are also flood control measures along the Assiniboine River.
Flood protection work has prevented property damage and reduced the potential impact of flooding on families and communities. Since the 1997 flood, more than $1 billion has been invested in flood mitigation efforts in Manitoba.
