Brandon experienced an inflow of water from the Shellmouth Reservoir on Saturday, resulting in water flooding the soccer pitches along First Street North. That area remains under water and is closed to public access, as are all recreational areas along the Assiniboine River corridor.
Water levels, as measured at First Street, continue to sit at a level around 358 metres above sea level, though precipitation is forecast in the coming days and could increase that. Officials say they anticipate a peak level of 358.4 metres above sea level; however, the arrival of the crest might occur anytime from today through Thursday.
The city’s current response plan takes into account a safety margin of two feet above those predicted peak levels. Several pumps have been placed at key areas along the dike system and will be activated if needed. Work is planned along the city’s dike system to block affected outflows, including one at Knowlton Drive.
A response plan is also in place to close Grand Valley Road if water begins to flood over the roadway.
A provincial flood warning remains in effect for all of the Assiniboine River between the Shellmouth Dam and Brandon. The province estimates that about 30,000 acres of agricultural land have been affected.

Emergency crews scrambled to city dikes over the weekend after warnings that the Assiniboine River was spiking.
However, although the river is high — and getting higher — it wasn’t at the extreme range that instruments suggested.
Automated readings showed a sudden surge on Saturday night to a river level of 361.18 metres above sea level — a new record that would have been more than 30 centimetres above the level recorded in 2011, and closing in on the all-time estimated record from the Great Flood of 1882.
In fact, however, water levels were not that high. They were actually about three metres lower, at a level that is similar to where they are now.
The city’s electronic gauge and other infrastructure were inspected Monday morning to ensure accuracy.
