How we’re responding

How we’re responding

  • We’re continuing to monitor rainfall and river conditions 24/7.
  • We are communicating regularly with Environment and Climate Change Canada, Alberta River Forecast Centre and TransAlta to share the best available information.
  • The Springbank Off-Stream Reservoir (SR1) worked with the Glenmore Reservoir to store water along the Elbow River, and is now gradually releasing stored water back to the Elbow River.
  • Ghost Reservoir on the Bow River upstream of Calgary is limiting downstream flows as it returns to normal operating levels.
  • Crews, equipment and materials remain ready to respond to changing conditions.
  • In preparation for flood season each year, The City completes exercises and testing of infrastructure like river outfalls, lift stations and temporary barrier deployments.

What you can do

What you can do

Stay safe near rivers

When the rivers and creeks rise in Calgary, stay away from the banks, including children and pets, as high flows can cause bank erosion and instability. Before going out on the river (rafting, fishing, kayaking), check calgary.ca/watersafety. When a boating advisory is in place, stay off the river for your safety.

Direct rainwater away from your home

Eavestroughs and extensions should drain at least 1.5 meters (5 feet) away from your and your neighbour's home and onto a landscaped area so the water can soak into the ground.

Ensure your basement is flood resilient

When river levels are high, and/or when it rains heavily, water can enter basements. Check your sump pump and backflow valve if you have them, to make sure they are in good working order. Consider moving valuable or sentimental items to higher levels. Consider installing a water alarm to for an early alert about any water entering your basement. Check your insurance policy to see if you’re covered for groundwater basement flooding. Visit Basement flooding and seepage to learn more about basement seepage.

Help us keep an eye on storm drains

During intense rainfalls, storm drains can be temporarily overwhelmed and it may take some time for water to drain. In some areas of the city, we’ve installed a device in the storm drains to manage how fast water flows into the pipes from the storm drain that helps prevent the system from becoming overwhelmed with stormwater, avoiding water backups into basements or flooding into houses, garages and businesses.

If you see water pooling around storm drains and it hasn’t drained within 90 mins, take a photo and submit it via the 311 app or online request. This will help City crews respond on a priority basis. If safety is a concern or water is entering a building, contact 311 immediately.

A note about online AI-generated flood forecasts:
The City and Provincial River Forecast Centre are aware of various AI generated flooding reports, such as Google Flood Hub. Please note that forecasts from official local sources, such as The City and the AB River Forecast Centre, account for weather model uncertainty, reservoir operations, and advisory levels, and take into account knowledge of on-the-ground flood thresholds that include community flood protection measures. The City, River Forecast Centre and Environment and Climate Change Canada meteorologists are in close contact, and local emergency managers will issue the appropriate advisories as required.

Next update: Friday, July 10, 2026

Flood resources

We can’t prevent flooding entirely, and it can happen quickly with little or no warning. Protecting our community and citizens from flooding is a shared responsibility – we all have a role to play.

  • View flood maps

    Know your flood risk. Search for your property on our flood mapping tool to see if you are at risk for flooding.

  • Prepare for flooding

    Take steps to reduce flood damage to your home and ensure your family knows what to do if a flood happens. Find preparation resources on this page, including guides in Traditional and Simplified Chinese.

  • Stay informed

    Sign up for e-mail alerts and find a list of flood notification resources, including City of Calgary emergency notices.

Did you know?

Flooding can occur even during dry conditions.

Although Calgary has a dry climate, flooding is always possible. With our proximity to the mountains, we can experience unpredictable swings in the weather, from heavy rains leading to floods, to many weeks of dry temperatures and little rain leading to droughts.

Flood mitigation projects

Calgary is better prepared today for flood events like the one in 2013. We’ve taken steps to reduce Calgary’s exposure to flood damage that have reduced our flood risk by 70 per cent as of 2026.

Sunnyside Flood Barrier

The communities of Sunnyside, Kensington and Hillhurst are now protected from a 1-in-100 flood, due to the functional completion of the Memorial Parkway / Sunnyside Flood Barrier. The 2.4 km barrier includes a combination of permanent concrete and metal flood walls, with additional temporary barriers to close gaps across roadways and pathways during flood response.    

Springbank Off-Stream Reservoir

Calgary’s Elbow River communities are now protected from 2013-sized floods, thanks to the new Springbank Off-Stream Reservoir (SR1) located along the Elbow River, upstream of Calgary. The ‘dry' reservoir will only be filled during floods, and will work together with the Glenmore Reservoir to significantly increase the overall floodwater storage capacity on the Elbow River.
