Winnipeg, MB - Today, the Province updated its flood forecast due to the cooler than normal temperatures that are preventing ice breakup on the Red River. Given the cool temperatures we have experienced in the past two weeks, it is anticipated that ice along the Red River upstream of the floodway and within the City of Winnipeg may still be intact when the Red River crests within the city. If the ice cover remains intact, it is estimated the Red River water level at James Avenue could see an ice-induced crest of 18.2 to 18.7 feet.
City staff have been undertaking flood preparations for several weeks. As the river has been rising for the last week, the City has begun activating flood pumping stations, checking flood control gates and setting up temporary pumps.
Grant Mohr, Flood Planning Engineer with the City’s Water and Waste Department, says “Based on the revised forecast, the City estimates that there are three properties that will require sandbags. City crews will be contacting the residents of these properties shortly. It is estimated that about 2,300 sandbags will be required for these properties.” Mohr adds “We continue to monitor river levels and will adjust our plans accordingly.”
High river levels increase the risk of basement flooding across the city. When river levels are high, the normal capacity of the sewer system is reduced. With heavy rains, there is an increased risk of overloaded sewers backing up through house sewer lines and flowing into basements that aren’t protected.
Although basement flooding is a risk at any time of the year, the risk increases with high river levels because the sewer system must then rely heavily on pumping stations rather than gravity to carry the rainfall runoff.
Homeowners are reminded to take steps to protect their homes and property.
- Residents who live along the river should move or secure any structures or equipment near the water’s edge, such as docks, sheds, gazebos, irrigation pumps, and recreational equipment. The rising river level will affect each property owner differently.
- To ensure maximum protection against basement flooding, arrange for a licensed plumber to install a sewer line backup valve and a sump pit with pump in the basement.
- Inspect backup valves and sump pump drainage systems to make sure they are functioning properly.
- Ensure drainage is directed away from the home by extending downspouts away from the basement walls and ensuring the earth is built up around the house.
Property owners are reminded it is against the law to drain sump pump water into the basement floor drain or any other part of the house plumbing system, as it can overwhelm the sewer system placing their basement and those of their neighbours at risk of flooding and damage.
