Oregon's IWRS provides a statewide inter-agency framework for better understanding and meeting Oregon's instream and out-of-stream water needs. Oregon's Water Resources Commission adopted the first IWRS in 2012 and the second in 2017. Oregon Revised Statute (536.220) was updated in 2023 to require that the IWRS is updated every 8 years.
