We're advising Calgarians that alpine snowmelt and forecasted rain are expected to increase river flows and water levels in the Bow and Elbow rivers between now and Tuesday. High streamflow advisories, a boating advisory and pathway underpass closures are expected to begin this weekend. We are asking everyone to exercise caution around rivers and low-lying pathway areas.
Our current outlook:
* No river flooding expected in the next five days.
* Currently, warmer temperatures are driving snow melt and increasing runoff in both rivers. However, both rivers remain within normal spring levels for this time of year.
* A cold wet front is expected this weekend, with forecasts indicating between 40-60 mm of precipitation. This is anticipated to increase flows on both rivers, resulting in some pathway closures.
How we're responding:
* Some pathway closures due to increased flows expected over the next few days.
* We’re continuing to monitor 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.
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. 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.
* 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.
