Flooding

One of the most important responsibilities of the GRCA is protecting people and property from flooding.

The Grand River system has a long history of flooding. Floods can occur in all seasons: during the spring melt, following major rainstorms in summer and fall, and during a snap melt or because of an ice jam in the winter. (You can see historical flooding photos on our Flickr page.)

The GRCA manages floods by:

• monitoring weather conditions and river flows to know when flooding is possible;
• issuing flood messages to alert municipal flood coordinators and the public about coming high water;
• operating seven dams and reservoirs to hold water and reduce flood peaks;
• owning and maintaining dikes to protect low-lying areas in Kitchener (Bridgeport), Cambridge (Galt) and Brantford; and
• controlling development in flood-prone areas to reduce potential property damage.
