Instream flow status

In consultation with Washington State Department of Fish and Wildlife and the Tribes, Ecology adopted the “Instream Resources Protection and Water Resources Program” rule (Chapter 173-505 WAC) in August 2005.

The rule:

  • Established instream flows for 32 rivers and streams.
  • Reserved a limited amount of groundwater for future domestic use.
  • Reserved a limited amount of water for stock watering.
  • Established maximum limits for withdrawals from nine water sources.
  • Closed lakes and ponds to new diversions (except for domestic use).
  • Closed numerous rivers and streams to new uses unless the use qualifies under identified exceptions.
