The bill aims to facilitate the filing of adjudication claims for precode uses of groundwater and surface water in the water resource inventory area 1 (WRIA 1) water rights adjudication, specifically for Whatcom and Skagit counties. It builds on the procedures established during the Yakima basin water rights adjudication, ensuring that water users can apply similar processes in WRIA 1. The legislation amends RCW 90.14.043 to allow individuals to file claims without being restricted by time limitations, provided they obtain certification from the pollution control hearings board. This certification can be granted if the applicant demonstrates continuous beneficial use of water since specified dates or from the date of a court decree confirming a water right.

Additionally, the bill introduces new provisions that allow for the filing of adjudication claim forms in WRIA 1 after June 1, 2023, which will satisfy the requirements for filing a statement of claim. It clarifies that such filings will not affect existing water rights prior to July 27, 1997, and establishes that any new water rights claimed will be subordinate to previously established rights. The bill emphasizes the importance of ensuring that the adjudication process is accessible and fair for all water users in the region.
