• A widespread system is moving into Alberta over the weekend with the majority of rain falling on Sunday and early Monday in the Bow and Elbow Catchments.
• River flows are currently within the normal range for this time of year but are expected to modestly increase early next week due to the forecasted rainfall.
• The City is monitoring the weekend forecast closely, but at this time overbank river flooding is not expected.
• The scale of this event is currently expected to be similar in size to the event in early June, potentially resulting in wet low-lying areas near the river, some pathway closures at underpasses near the river, and possibly a boating advisory. 

• 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.
• City stormwater crews are monitoring and responding to drainage concerns.
• Reservoir levels are positioned to be able to store high river flow as needed.
• Crews, equipment and materials are ready in case conditions change and we need additional response.
• In preparation for flood season each year, The City completes exercises and testing of infrastructure like river outfalls, lift stations and temporary barrier deployments.
• We are prepared to communicate as needed through the event, should conditions change and additional actions be required.

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. If there is a boating advisory, 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.

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.

Weather and river conditions in Calgary can change quickly and without notice.

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.
