Providing Data for the Integrated Report

Section 303(d) of the Clean Water Act requires each state to identify waters of the United States that do not meet or are not expected to meet by the next listing cycle, applicable water quality standards and to prioritize those waters for total maximum daily load development, unless other corrective action is appropriate. Section 305(b) of the Clean Water Act requires each state to report on the overall condition of its surface waterbodies. California combines its 303(d) lists and 305(b) reports into a single “California Integrated Report.”

Information and instructions for providing data for the integrated report are available on the Submitting Data and Information for the Integrated Report webpage.

Detailed information on data solicitation, data submission, CEDEN, the Integrated Report Upload Portal, and the listing cycles are available on the State Water Board Water Quality Assessment program webpage.

If you have questions about submission requirements for the Integrated Report, the Listing Policy, or uploading to the Integrated Report Document Upload Portal, please see the Surface Water Quality Assessment page or email WQAssessment@waterboards.ca.gov.

Preparing your data to meet CEDEN and Integrated Report requirements can be time consuming and the vocabulary request process can take several weeks of processing time, so please plan accordingly.
