Delta Plan Amendments

Introduction to the Amendment Process:


Adopted by the Council in May 2013, the Delta Plan anticipated the need for periodic reviews and updates in response to changing circumstances and conditions in the Delta unrelated to the Water Code section 85300(c) requirement that the Council review the entire Delta Plan no less than once every five years. For information about the current five-year review, click here.



One update is now being considered for Chapter 4 (Protect, Restore, and Enhance the Delta Ecosystem)


When the Council approved the Delta Plan in 2013, it adopted policies and recommendations in Chapter 4 directing agencies to restore aquatic habitat and improve water quality while respecting local land uses and expanding opportunities for nature-based recreation and tourism. While that general direction holds true, much has changed in the past five years.


Through a public process lasting through early 2019, the Council will work with partner agencies, stakeholders, and the public to build upon, further refine, and amend Chapter 4 of the Delta Plan. Currently, the chapter includes regulations covering flow, introduction of nonnative invasive species, and criteria for priority restoration sites. To learn more, please click here.

  • Glossary was amended to include three new terms included in the Delta Levees Investment Strategy.

Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
