Government of British Columbia

Glaciers and ice masses for the province, derived from aerial imagery flown in the late 1980s and early 1990s. Please refer to the Glaciers dataset for recent glacier extents in British Columbia, and Historical Glaciers for a comparable historic view.

Links the edge type codes used in the stream network layer with an English description used to categorize stream network features

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

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

All wetland polygons for the province

Named point features (both fresh and marine) such as points of land, etc. Point names included as an attribute

Bay and Channel (fresh and marine) features and associated names

Water obstacles (rapids, falls, etc)

Lookup table for watershed type codes

Linear coastlines of BC, including mainland and marine islands. Lines are directionalized and connected. Attributes include a hierarchical key and route identifier

All lake polygons for the province

All named watershed polygons

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)

All manmade waterbodies, including reservoirs and canals, for the province

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

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.

All double line river polygons for the province

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

All island polygons. Islands may overlap as there are islands within islands (e.g., a lake on an island contains an island). GNIS_NAME_1 contains the most atomic name for the island. For example, there are 3797 "Haida Gwaii" islands. If the island has not been named as part of a more specific...
