California State Water Resources Control Board (SWRCB)

The State Water Resources Control Board is launching a new and improved system called CalWATRS (short for California Water Accounting Tracking and Reporting System) to make reporting water rights easier and more efficient. This system will help the state manage water data better and make it easier for the public to access important information.

What You Need to Know

Early Access Starts in July 2025 You’ll be able to explore and get used to the new CalWATRS system from July through September 2025. This is your chance to try it out before official reporting begins. Look for more information on the CalWATRS website.
Official Reporting Begins October 2025 You can start submitting your water rights reports to CalWATRS in October 2025. Reports for the 2024-2025 water year will be due by January 31, 2026. More details and instructions will be shared closer to October.
Current System (eWRIMS) Will Close June 8, 2025 The current system, eWRIMS, will stop accepting reports on June 8, 2025. You’ll still be able to search for water rights information in eWRIMS after that, but you won’t be able to submit anything new.
No Changes to Old Reports from June 8 – September 30, 2025 During the switch to CalWATRS, you won’t be able to edit or amend past reports between June 8 and September 30, 2025. If you need to make changes to old reports, do it before June 8 in eWRIMS, or wait until after October 1 in CalWATRS.
CalWATRS Website and Email Updates The CalWATRS website is your go-to hub for the latest news, system updates, and helpful resources. While you’re there, sign up for the CalWATRS email list to receive important announcements and helpful information straight to your inbox.
