Chapter 173-201A WAC, (salmon spawning habitat)

We have started a rulemaking to revise chapter 173-201A WAC, Water Quality Standards for Surface Waters of the State of Washington.

This rulemaking will consider revising WAC 173-201A-200(1) Aquatic life uses, to provide additional water quality and habitat protection for early life stages of salmonids—including salmon, steelhead, and trout—and their spawning gravel. We will consider two general revisions in this rulemaking:

  1. Revising the freshwater dissolved oxygen (DO) criteria to better protect early life stages of salmonids in spawning gravel.
  2. Adding fine sediment criteria to provide additional protection for spawning gravel habitat.

Other sections of Chapter 173-201A WAC may be amended, as necessary, to support any revisions to the sections noted above.
