The notice posted below commences the data and information solicitation period for the 2026 California Integrated Report. The State Water Board is soliciting surface water quality data and information to inform the compilation of the 2026 California Integrated Report. Data and information received may be used to identify impaired waters (i.e., waters not meeting water quality standards) and overall surface water quality conditions.
The listing cycle for the 2026 Integrated Report focuses on surface waterbodies such as rivers, streams, lakes, reservoirs, estuaries, lagoons, bays, and ocean waters in the following areas of California:
- The regions of the North Coast, Lahontan, and Colorado River Basin Regional Water Boards.
- The San Joaquin River sub-area of the Central Valley Regional Water Board, which is defined as the San Joaquin River watershed and includes the mainstem of the San Joaquin River upstream of the legal boundary of the Sacramento-San Joaquin Delta and all surface waters tributary to the mainstem.
The attached notice contains instructions to follow when submitting data and information to the State Water Board. The data and information submission process could take several weeks. Data and information submittals should be done as soon as possible to reduce and avoid backlogs in data and information uploading.
Data and information submissions must be received by the State Water Resources Control Board no later than 12:00 p.m. noon on October 21, 2022.
Questions regarding data or information submittals, or about other information included in the notice, should be directed to WQAssessment@waterboards.ca.gov.
The notice, including enclosures, and additional information about the Integrated Report are available on the Surface Water Quality Assessment webpage.
