What is OGWA?
The Ottawa-Gatineau Watershed Atlas (OGWA) is a community-based water information hub. OGWA combines information from many different sources and paints a holistic picture of the 5 subwatersheds.
A comprehensive guide to all things water. Read about the importance of water in your community, where it comes from, how it is impacted, who manages it and how you can protect it. Link from this information to facts and data on the water where you live.
We all live in a watershed - a watershed is an area of land that is drained by a river and its tributaries into a particular body of water such as a pond, lake or ocean. Do you know which watershed you live in? Find out by clicking here.
