Click here for the Delta Regional Monitoring Program Monitoring Design Review Final Phase



The Delta Regional Monitoring Program (Delta RMP) was initiated by the Central Valley Regional Water Quality Control Board (Regional Water Board) to fulfill the unique need for a comprehensive effort to assess and track water quality constituents and their effects in the Delta to provide a scientific basis for water policy and documenting the effectiveness of beneficial use protection and restoration efforts.


The development of the Delta RMP was initially prompted by the collapse of several pelagic fish species in the early 2000s, an event that triggered new inquiries into the potential role of contaminants in what is now termed the Pelagic Organism Decline; however, these inquiries more broadly highlighted the shortcomings of existing monitoring efforts to address similar questions at the scale of the Delta.


A Monitoring Design for the Delta RMP (Monitoring Design) was approved in June 2015 and monitoring for pesticides and pathogens began that same year.


The purpose of this review is to provide an independent and objective assessment of the Monitoring Design.


This effort will involve an initial and final review of the 2015 Monitoring Design. The Delta Science Program will host this review in accordance with its mission to provide the best possible unbiased scientific information to inform water and environmental decision making.

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)
