The floods in Manitoba
Seeing that the Red River has a natural propensity to floods, Manitoba's authorities had to initiate preventive measures in order to diminish the flood risks. A large amount of money was invested in protective structures to minimise damages in case of a flood.

Over 100 kilometres of dyke-boulevards and pumping stations were built in and around Winnipeg immediately after the devastating 1950 flood.
These protective structures have since saved the Winnipeg population 18 times and, according to estimations, may have spared the city of 3 billion dollars in additional damages. A governmental commission estimated that each dollar invested in protective structures could help save 2,73$ should a flood arise.
Permanent earth
dykes also protect
eight cities to the
south of Winnipeg.
The city of Morris is one of the communities encircled by a permanent dyke. Even though it looked like an island during the 1997 flood, it actually was lower than the flood level. The city of Morris was spared from the waters thanks to the dyke system.
On top of the protective structures around the cities, many land and farm owners have erected their own permanent dykes around their buildings to protect themselves from the frequent flooding.
Some private landowners called on to a solution other than dykes to protect their houses. This system consists in building their houses on mounds.
