Watersheds

Frontenac Arch Biosphere encompasses four different tertiary watersheds (Cataraqui, Rideau, Napanee, and Upper St. Lawrence – Thousand Islands). 

Watersheds are delineated by an area of land that catches rain and snow and drains or seeps into the same place such as the St Lawrence River (through marshes, streams, rivers, lakes, or groundwater). You can explore the Frontenac Arch Biosphere’s watersheds on the maps to the right (view map for the interactive version and click features to display background information).
