Municipalities across southern Alberta are mobilizing emergency response efforts as forecasters warn of significant flooding risk along the Bow River and surrounding waterways this week.
Environment Canada issued a yellow rainfall warning Sunday morning for Calgary and much of Alberta, with meteorologist Erin Staunton confirming the alert remains in effect through Wednesday. The combination of melting alpine snowpack and heavy precipitation is expected to push water levels dangerously high, threatening low-lying communities and infrastructure.
What's at Risk
A flood watch is currently active for the Bow River and Pipestone River near Lake Louise, with water levels expected to climb throughout the week. Environment Canada has also issued a high streamflow advisory spanning from upstream Banff to Ghost Reservoir, with an additional 30-centimetre rise forecast for Friday alone.
Communities in Banff face particular concern, while Canmore and Exshaw residents should prepare for potential groundwater flooding. Several additional high streamflow advisories have been issued across southern and central Alberta as conditions deteriorate.
Current Conditions
Observers have documented increased debris flowing through the Bow River—a sign of the force and volume of water moving downstream. The debris creates additional hazards, potentially blocking culverts, damaging bridges, and complicating rescue operations if water levels breach banks.
Calgary residents living in flood-prone neighbourhoods are advised to review emergency preparedness plans and monitor official city updates closely. Those in areas with a history of flooding should consider moving valuables to higher ground and having documents and irreplaceable items secured.
What You Should Do
Stay informed by checking Environment Canada's website for updated warnings and watches. Follow local municipal emergency management social media accounts for real-time information about closures and safety advisories. Avoid approaching swollen rivers and creeks—currents are far stronger than they appear.
Alberta Emergency Management Agency continues coordinating response efforts with municipal partners. Residents should have emergency kits prepared and know evacuation routes if ordered by local authorities.
