Found 10 records similar to Freshwater Atlas Assessment Watersheds
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
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 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
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)
Lookup table for watershed type codes
Flow network arcs (observed, inferred and constructed). Contains no banks, coast or watershed bourdary arcs. Directionalized and connected. Contains heirarchial key and route identifier
Human activities occurring on land can impact marine coastal ecosystems. Baseline information on the locations and intensity of these activities are critical components of any impact assessment or spatial planning approach seeking to mitigate stress and protect or restore coastal ecosystems. As part of a wider project, land use maps were created for 109 coastal watersheds draining into the Scotian Shelf Bioregion – a biophysical subdivision of Canada’s marine waters in the Maritimes Region of Fisheries and Oceans Canada. Information was compiled from various national and provincial publicly available spatial data sources.
This file contains a representation of 3rd order watersheds developed for the 1:50,000 BC Watershed Atlas with each watershed polygon coded for occurrence of freshwater fish species (including anadromous salmon in their freshwater stages). The initial fish species codes for presence/absence in each watershed were derived from an GIS overlay of fish species occurrences within broadly defined fish regions for BC. This overlay of fish ranges describes the occurrences of fish species in 30 regions throughout the province. These broad species ranges were derived from McPhail and Carveth's 'Key to Freshwater Fish of BC' and refined further based on the most current expert opinion.
