• No river flooding expected in the next five days.
• Today through Saturday, we’re expecting highs up to 29°C, with a chance of showers today and Friday.
• Flows will continue to stay steady or subside slowly through the week.

Summary of the 2026 high flow season:

• Snowpack conditions were above average, approximately 120 – 150 per cent of normal.
• Precipitation from mid-May to mid-July was above average, approximately 150 per cent of normal.
• We experienced two significant rain events:
  • May 30–June 1: Approximately 100 mm of precipitation fell on eastern slopes, with up to 150 mm in the Jumpingpound Basin. Combined with elevated snow melt, this raised flows on the Elbow River to 86 m³/s and on the Bow River to 474 m³/s.
  • June 27–29: Approximately 150 mm of precipitation fell on eastern slopes. With the intense rainfall, Elbow River flows recorded a peak flow of around 250 m³/s (at Bragg Creek, early morning on June 29) and 558 m³/s (Bow River at Calgary; late evening on June 29).
• The Springbank Reservoir operated for the first time ever, diverting 13 million cubic metres of floodwater. All water was released back to the Elbow River by July 10.
• Elbow River flows downstream of Glenmore Dam were maintained below 80 m3/s and the reservoir level was maintained below crest level. 

• No impacts at this time.
• We’re continuing to monitor rainfall and river 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.

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 that will give you an early alert if there’s 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.

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.
