eWRIMS Electronic Water Rights Information Management System

The Electronic Water Rights Information Management System (eWRIMS) is a computer database developed by the State Water Resources Control Board to track information on water rights in California. eWRIMS contains 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.

eWRIMS Database (View Water Rights)

The eWRIMS Database System provides information about water rights throughout California. You can search for water rights by several criteria, including the water right owner's name, watershed, stream system, and county.

The eWRIMS Web Mapping Application provides the spatial location of water rights throughout California. Using a Geographic Information System (GIS), you can search search for the location of water rights by visually displaying the location of point(s) of diversion on a map or aerial photograph. If you find water rights using this method, you can use the eWRIMS Database System (above) to search for information about the water rights.

eWRIMS Report Management System (RMS)

The eWRIMS Report Management System (RMS) is used by water right holders to submit the reports required as a result of their diversion and use of water. Four types of water use reports are supported by the system:

  1. Supplemental Statement of Diversion and Use
  2. Report of Licensee
  3. Progress Report by Permittee
  4. Groundwater Extraction Notice

The Division of Water Rights submits annual notices to water right holders that are required to submit reports. If you have a water right but have not received notification, either (1) it may not be your year to file or (2) your address and ownership information may not be current in our records. Having current contact information for Statement, License, and Permit holders helps us protect your water rights.  It is your responsibility to keep your address and ownership information current with the State Water Board.

eWRIMS Help Center

If you need assistance with using eWRIMS or RMS, or if you have questions about a specific water right or project, the Division of Water Rights maintains an eWRIMS Help Center available here:
