Statutory Adjudication of Water Rights in the Fresno River Watershed

On October 20, 2020, the State Water Board granted a petition by the Madera Irrigation District for the statutory adjudication of the Fresno River, directing State Water Board staff to proceed with the determination of the rights of the various claimants to the water of the Fresno River stream system. Parties in the lower Fresno River had previously been given time to negotiate an alternative agreement to resolve the issues outlined in the petition following its submission to the Board in October 2018.

A statutory adjudication is a proceeding by which the rights to water in a stream system are determined through a State Water Board proceeding and court decree. California Water Code sections 2500-2868 and California Code of Regulations Title 23, sections 945-951 describe the State Water Board’s process in conducting a statutory adjudication. Previous statutory adjudications conducted by the Board are listed on the Division’s Water Rights Judgments and Determinations page.
