River flooding in Calgary

River flooding in Calgary

High river flow season is May 15 - July 15

The 2023 high river flow season has ended for Calgary. Daily river condition updates will return in May 2024.

Did you know?

Calgary is a dry climate, and because of 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.

Unlike floods, which can happen very quickly, droughts develop slowly over time. Calgary is most at risk of experiencing a drought from mid-July to the end of September. A drought can last anywhere from weeks to months and can evolve into multi-year droughts if the region is consistently not getting enough moisture.
