Over the last few months, Team Ward 9 has been to community association meetings and events and has spoken with many concerned Ward 9 neighbours and business owners in our flood-affected communities. With spring in full swing, there is one common issue on their mind – what is going to happen during Calgary’s rainy months?

We’ve put together some quick information for your reference:

·         Alberta Environment provides advisories and warningsflow rates and river forecast comments.

·         The City will continue to update information on flood recovery and mitigation at

·         Important updates will be distributed via email as the situation warrants or you can also follow The City on Facebook and Twitter.

Can Calgarians expect flooding in spring?

Some amount of flooding occurs in Calgary every spring. The period between May 15 and July 15 is when Calgary typically receives the largest amount of rainfall and the highest rate of snowmelt, two main contributors to overland flooding.

The City of Calgary, Calgary Emergency Management Agency and our partners, such as Environment Canada and Alberta Environment and Sustainable Resource Development  continually monitor snowpack levels, river and stream flows, and ground saturation levels.

Alberta Environment and Sustainable Resources (AESRD) provides river forecasts. Their numbers are calibrated from information received from reporting stations. There is a two-hour delay in the information they post as it is received from various stations. You can access the Province’s most current forecastsand forecasters’ comments through AESRD.

The City of Calgary Water Services team uses the AESRD information to model forecasts and flows in order to respond as necessary to high river flows.

For more information on the many ways to stay updated on conditions and understanding river monitoring, visit The City’s flood information website.
