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.

Electronic Water Rights Information Management System (eWRIMS) Database The eWRIMS Database System provides information about water rights throughout California. It includes information on Statements of Water Diversion and Use that have been filed by water diverters, as well as registrations, certificates, and water right permits and licenses that have been issued by the State Water Resources Control Board and its predecessors. You can search for water rights by several criteria, including the water right owner's name, watershed, stream system, and county.

Points of Diversion (PODs) Points of Diversion (PODs) are locations where water is being drawn from a water source such as a stream or river. The point locations in this service were derived by extracting the best known location information from the POD table from the WRIMS database supplied by the California State Water Resources Control Board. This service should be used for general mapping of Points of Diversion. Because of source data irregularities, some POD locations may be inaccurate by as much as half the width of a Public Land Survey System section.
