An environmental summary created by the ENVS 560/L Watershed Systems class at CSUMB.


This page requires further development. The goal of this page is to have two major sections for acquiring information about anadromous species and their habitat in the Pacific Northwest (PNW). One can give you geographical information about a single species accross the entire region, the other will provide a more ecological context by listing all anadromous species present in a specific location.

Special Note: There will likely be more information and more accurate information available for species of special concern (state and federally listed species), and useful sources for information include federal and state agency prepared documents.

1. The first section should be titled (Species Range) and it should list all anadromous species that occur in this region of the United States (i.e., WA, OR, CA), it should have a brief description of their range, a map of their range, and a link to a species-specific page if it exists. At the bottom of this section there will be a list of species declared extinct in this region since the beginning of record keeping.

2. The second section, which may end up being a separate page, should have three subheadings to organize the information by state, and under each state subheading there should be a list of MAJOR waterbodies, watersheds, and hydrologic features of the state. Paired with these waterbodies should be a downloadable source or link to a source which clearly describes the anadromous species present.

Species Range

  • Coho salmon
  • Coastal Cutthroat trout
  • Chinook salmon
  • Chum Salmon
  • Pink Salmon
  • Sockeye salmon
  • Steelhead
  • American shad
  • Eulachon
  • White sturgeon
  • Green sturgeon
  • Pacific Lamprey

Species by Hydrologic Boundaries


California is separated into 10 Hydrologic Regions and management strategies for anadromous species varies throughout these regions. General fish species information for California can be found on the California Department of Fish and Wildlife Fishes page.[1]


Species in Oregon can be organized into eight Hydrologic Units.

  • Central Coast/Upper Willamette Basin
  • Deschutes Basin
  • High Desert Basin
  • John Day/Umatilla Basin
  • Lower Willamette Basin
  • North Coast Basin
  • Snake River Basin
  • Southwest Oregon Basin
