FWA Assessment Watersheds for GEOS Analysis, BC

The Freshwater Atlas (FWA) is a standardized dataset for mapping the province's hydrological features. The atlas defines watershed boundaries by height of land and provides a connected network of streams, lakes and wetlands. Each stream in the province has its own watershed (the land drained by that stream) but it is also linked to the other streams and watersheds around it.

This allows you to connect a stream to both its tributaries and the watersheds associated with them. Simply put, you could, conceptually, launch a paper boat in the headwaters of a small creek in the interior and trace its route to the sea. You could also identify all the wetlands, lakes and watersheds your boat passed through.
