GeoBC Freshwater Atlas Delivery

The four largest Freshwater Atlas (FWA) datasets exceed the maximum size supported by the Data Catalogue Custom Download and cannot be downloaded in their entirety at the full provincial extent using that method. Therefore, when using that download service, a smaller area of interest must be specified to download portions of these four larger datasets: Because of this BC Data Catalogue download size limitation, the complete Freshwater Atlas, at the full provincial extent for all datasets, is provided through cloud storage below.

Data Downloads

Stream Networks Contains stream network line features for the entire province, organized by watershed group.
Linear Boundaries Contains linear boundary features for the entire province, organized by watershed group.
Watershed Boundaries Contains watershed boundary line features for the entire province, organized by watershed group.
Watersheds Polygons Contains watershed polygon features for the entire province, organized by watershed group.
