Salish Sea Bioregion Watersheds

Watersheds in the Salish Sea Bioregion. Created for the Salish Sea Atlas (https://wp.wwu.edu/salishseaatlas/). HUC-8 level US watersheds and sub-sub-drainage basin level Canadian watersheds that directly or indirectly drain into the Salish Sea. The watersheds at the northeastern and northwestern corners of the bioregion's boundary were clipped along sub-basin boundaries to remove portions of the larger watersheds that drain into Johnstone Strait or Bute Inlet rather than the Salish Sea. All processing and analysis was completed using the NAD 83 UTM Zone 10N projection and coordinate system.
