Last revised: August 07, 2019

View of a river from the bank The Streamflow Restoration Act (RCW 90.94) is a new law affecting water resource management in Washington State. The law, passed in 2018, helps protect water resources while providing water for families in rural Washington. 

The law directs local planning groups in 15 watersheds to develop or update plans that offset potential impacts to instream flows associated with new permit-exempt domestic water use.

Ecology is leading the WRIA 9 Duwamish/Green Watershed Restoration and Enhancement Committee. Get more information:

How the law affects this watershed

people fishing off the end of a wooden patioAs of Jan. 19. 2018, new permit-exempt wells for domestic use in this watershed are:

  • allowed 950 gallons per day as the maximum annual average (350 gallons per day during drought).
  • subject to a $500 fee.

Please contact your county for more information on these standards as they may change in the final watershed plan or any potential rulemaking.

This watershed:

  • has an instream flow rule that does not regulate permit-exempt wells.
  • is directed by Section 203 of the new law to adopt a watershed restoration and enhancement plan by June 30, 2021.


This committee has until June 2021 to complete plans that estimate the 20 year consumptive use from new permit-exempt wells and identify projects to offset that consumptive use. The plans will need to meet net ecological benefit. The standing meeting date for this committee is the 4th Tuesday of the month in the afternoon.
