Current river conditions, plus 2021 flood season resources

May 26, 2021 by CRC Action Group in News

Flood season is upon us yet again (May 15 to July 15) and we are fast approaching the eighth anniversary of the Southern Alberta Floods.

To keep things simple during these uncertain times, we’re sharing links to flood related resources, current river conditions, and a flood readiness newsletter from the City below.

The Glenmore gates upgrade was completed in September 2020. The gates will allow the city to fully mitigate a 2005-sized flood, and slightly reduce the effect of the 2013-sized flood.

Flood readiness campaign from City of Calgary


Each year during flood season, the City of Calgary undertakes a flood readiness campaign to share flood-related information and resources.

Similar to previous years, the campaign is focused on helping residents understand their flood risk, pointing them to resources that help them prepare and stay informed throughout the season.


You will see us sharing resources on our social channels and you can read a flood season newsletter the City has provided us below.

Flooding can happen quickly. Take simple steps to be ready.

By The City of Calgary

As we approach the time of year when Calgary is most likely to experience river flooding, we’re ready, but it’s important that you’re flood ready too.

On the Elbow River, the installation of higher gates on the crest of the Glenmore Dam completed last year has doubled the amount of storage in the reservoir so we can manage higher river flows in the spring (up to moderate level floods, similar to the flood in 2005). Along the Bow River, the TransAlta agreement to modify operations of the Ghost Reservoir during flood season has been renewed through 2026.

In preparation for this year’s flood season we’ve already lowered the reservoir, stockpiled riverbank protection and temporary barrier materials and trained staff to respond in case of an emergency.

While our staff are monitoring conditions 24/7 so that we can provide residents with the earliest possible warning if flooding arises, floods can still happen quickly, so it’s important to be prepared.

  1. Understand your risk. Check The City’s flood maps to find out if your home is at risk of river flooding.
  2. Be prepared. This includes taking precautions to prepare your family and your property.
    1. Move valuables and documents out of your basement.
    2. Review your emergency plan and safe accommodations in the event of an evacuation.
    3. Contact your insurance company to review coverage in the event you must evacuate.
    4. Check your downspouts, sump and backflow preventer valves as part of your regular home maintenance schedule.

  3. Stay informed.  River conditions can change quickly. Go to calgary.ca/floodinfo to sign up to get alerts.


What’s the status of the Springbank Reservoir (SR1) project?

Earlier this spring, the Springbank Reservoir completed the last step for regulatory approvals, and we’re eagerly awaiting decisions from the provincial and federal regulatory review process, which should be made this summer.
