Water Boards Data and Databases

The State Water Resources Control Board (State Water Board) and Regional Water Quality Control Boards (Regional Boards and collectively, the Water Boards) directs and collects vast amounts of data and information on the state’s water quality, quantity, and uses, as well as the agency business operations. On July 10, 2018, the State Water Board adopted an Open Data Resolution (Resolution No. 2018-0032) to increase the focus on data management and accessibility at the Water Board. The Water Boards Strategic Data Action Plan describes a set of strategic actions that, when implemented, would significantly improve the way we manage and use data and information for both internal facing operations and external facing decisions about California’s valuable water resources.

  Accessing Data

A subset of the datasets maintained by the Water Boards can be found on the State of California's Open Data Portal under the 'Water' category. That platform provides web services that enhance data accessibility, and we plan to continue adding datasets to that platform in the future. Note that the datasets found on that site mirror some of the datasets described in the table below.

For questions regarding a specific database or dataset, please use the contact information provided for that program or database. For general questions regarding the content covered in this webpage, or if you cannot locate the contact information for a specific database, please contact the Water Boards' Office of Information Management and Analysis (OIMA) at OIMA-Helpdesk@waterboards.ca.gov.

CIWQS Sanitary Sewer Overflows (SSO) Report Sanitary sewer system agencies covered under Statewide General Waste Discharge Requirements for Sanitary Sewer Systems (WQO No. 2006-0003-DWQ), referred to as Enrollees, are required to report all Sanitary Sewer Overflows (SSOs) for which their agency has responsibility into the State Water Resources Control Board’s SSO database. Enrollees are also able to report sewage discharges from privately owned laterals or collection systems (known as private lateral sewage discharges, or PLSDs), for which the Enrollee has knowledge of the event but is not responsible, on a voluntary basis. The SSO Report allows users to view summary information of SSOs and PLSDs reported by Enrollees, as well as complete reports submitted for specific sewage discharge locations.
