Contains all primary and secondary matches between 1:20K and 1:50K stream edges. This attribute table links the new Freshwater Atlas watershed codes with the existing 1:50K Watershed Atlas watershed codes for cross reference purposes

Assessment Watersheds are mesoscale aquatic units designed to replace the 3rd order 1:50K watersheds. Assessment Watersheds are based on groupings of fundamental watersheds using FWA watershed code and local code, with a target size of between 2,000ha and 10,000ha.

Lookup table for watershed type codes

One of the spatial views of the BC WATERSHED ATLAS 50K, which is the digital basemap representation of the aquatic Man-made waterbodies, Wetlands and Double-line Rivers based on the 1:50,000 scale Canadian National Topographic Series of Maps.

All principal and non-principal watershed boundary edges. These are the linear features that makeup the watershed polygons

All fundamental watershed polygons generated from watershed boundary lines, bank edges, delimiter edges, coastline edges, and administrative boundary edges

All named watershed polygons

Flow network arcs (observed, inferred and constructed). Contains no banks, coast or watershed bourdary arcs. Directionalized and connected. Contains heirarchial key and route identifier

Polygons delimiting the watershed group boundary, which is a collections of drainage areas. In-land groups will contain a single polygon, coastal groups may contain multiple polygons (one for each island)
