Ottawa City Flood Levels

The City of Ottawa has worked very hard to understand what happens throughout the city as flood waters rise. They have used stream gauge correlation with field reconnaissance during a number of flooding events to develop a flood action plan. This plan looks at and establishes the “who, what, when, where, and why” of flooding within the City of Ottawa. It lays out a detailed protocol and procedure of what has to be done and at what stage/elevation during a flooding event.

The plan can be viewed at the following:

The City of Ottawa also has worked with a number of agencies to develop a flood inundation map/model.  This allows for users to look at locations within the City and analyze the extent and depth of water inundation at specific gauge elevations and increments.  This tool can be used at:
