Lakes, Rivers, and Creeks

Within the boundary of the Frontenac Arch Biosphere Reserve there are over 220 named Lakes, 2 major rivers (Cataraqui River and Gananoque River), approximately 80 Creeks, and hundreds of small unnamed water bodies. View the maps on the right hand side to further explore the numerous Lakes, Rivers, and Creeks spread out across the Frontenac Arch region.


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).
