All wetland polygons for the province

Points with rotations that indicate downstream flow direction. Can be displayed with arrow symbols to show flow direction. There is one point at the upstream end for each stream network feature

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)

Links the waterbody type codes used in the waterbody layers with an English description used to categorize waterbody features

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

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

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.
