Winnipeg, MB - The Province of Manitoba today released an updated flood outlook and advised that there is a risk of moderate to major spring flooding. The outlook noted that with the benefit of floodway operations, levels on the Red River would be James Avenue 4.6m (15 feet) for favourable weather or 5.5m (18 feet) in unfavourable conditions.
As of 12:38 p.m., on Friday, March 24, the river level at James Avenue was 2.5 metres (8.22 feet).
City engineers will use the Province’s latest information to generate an updated list of properties that may be at risk. It is expected that the identification of properties at risk will be completed during the week of March 27. Notices will be hand-delivered to property owners once identification of at-risk properties is complete.
The public is encouraged to follow the City of Winnipeg on Facebook and Twitter (#WpgFlood) for flood updates as well as reviewing flood information on winnipeg.ca/EmergWeb/.
City staff will continue to monitor river levels and work closely with the Province in monitoring the situation and adapt protection measures accordingly.
Springtime thaws also 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 overtax the sewer system placing their basement and those of their neighbours at risk of flooding and damage.
