The Sacramento-San Joaquin Delta Reform Act of 2009 requires the Council to review the Delta Plan at least every five years and revise it as needed. Consistent with the flexible decision-making framework known as adaptive management, the five-year review process ensures that the Delta Plan responds to changes in the environment, science, and knowledge, and the pace and uncertainty of climate change to stay the course in the pursuit of the coequal goals.

The first Five-Year Review and a highlights report can be found on the Council's website.

Delta Plan Performance measures help evaluate whether resource management actions recommended in the Delta Plan are producing the expected results. The Council developed quantitative performance measures based on the best available data, and science, and management relevance through an inclusive multi-year process involving state, federal, and local agencies, scientists, and more. These performance measures can be tracked on the Performance Measures Dashboard.

Additionally, watch our YouTube video to learn how performance measures are used to track the health of the Delta.
