CalWATRS is the state's new and improved water rights data system, replacing the legacy eWRIMS platform. With CalWATRS, water right holders now have a streamlined way to view all their water right records, file annual reports, and request water rights services.
* 2025 Annual Water Use Reports – Deadline Update
The deadline to submit 2025 Annual Water Use Reports was Saturday, January 31, 2026.
If you are still completing your report or working with staff to access your information in the CalWATRS system, continue submitting your report even if it is after the deadline. A 30-day grace period is available, and reports may be submitted through March 2, 2026 without penalty.
* Current Estimated Response Time: Two Weeks
Due to a high volume of requests, responses for CalWATRS assistance may take up to two weeks. We apologize for the delay and appreciate your patience. While you wait, we encourage you to visit the CalWATRS Resources webpage for materials that may help resolve your issue sooner. To help us respond more effectively, please provide your preferred method of communication and the best times to reach you when you email or call our help line.
* PINs Have Been Mailed
To access your water right records in CalWATRS you need a personal identification number (PIN). The State Water Board mailed PINs to primary owners and agents of water rights in October and November 2025. If you have not received a letter, please email CalWATRS-help@waterboards.ca.gov.
* Reporting Must Be Completed in CalWATRS — eWRIMS User IDs and Passwords Do Not Work in CalWATRS
Beginning this year, annual reports will be filed through CalWATRS. The previous platform, eWRIMS, is closed. CalWATRS accounts require a new username and password. Your eWRIMS username and password will not work in CalWATRS.
* For Businesses or Government Agencies
If you are part of a business or government agency, you will be able to create an "organization" within CalWATRS. This feature allows multiple staff or representatives to create their own accounts that can access and manage the organization's water rights.
