Fishway and Screening Rules

Rule-making status: Pending
Rule-making reference: #P2020-02

Summary of proposed rule

The rule proposal establishes standards for director approval for fish passage and screening, ensuring that fish can freely migrate and move through and around obstructions and are not harmed by man-made transfers of water flow from a natural system. The rule proposal defines terms, identifies standards for evaluating inadequate fishways and water diversions, and outlines compliance requirements and agency enforcement options. 

Based on public comments received on the rule publication, the department is currently revising its draft rules and will be refiling a supplemental rule publication.      

Scope and rationale for proposed rule

In November 2018, the Southern Resident Orca Task Force published its report (PDF) identifying lack of preferred prey as a key threat to Southern Resident Orcas. Recommendation 3 of the report endorsed agencies to apply and enforce laws that protect fish habitat. Specifically, the Task Force noted that the Governor should direct WDFW to develop rules to fully implement WDFW’s fish passage and screening authorities in chapter 77.57 RCW. During the past several years, WDFW has worked with tribal partners, local governments, and other stakeholders to develop rules to ensure fish passage and protection that would benefit fish and, ultimately, southern resident orcas. A new chapter 220-670 WAC will contain the new rules.
