The Assiniboine River flows through the northern end of the City of Brandon. Most of the developed areas of the city are located on the higher elevations outside of the Assiniboine River Valley floodplain. However, some industrial, commercial, residential and recreational properties and facilities exist within the floodplain, most notably the Brandon Flats area, located south of the river
between First Street and 26th Street.
The flood-prone properties are protected by dikes to varying degrees, but in general they are not high enough to protect against a 100-year flood.
To address this issue, the City of Brandon raised approximately 5 km (3.1 miles) of dike by about 0.6 m (2 ft), to a level about 0.3 m (1 ft) above the unfavourable predictions from the January and February flood outlooks for the 2011 spring flood. The Manitoba government is providing $781,000 to support the $1.07 million the city is investing in this project.
