From the State Water Resources Control Board:
The State Water Resources Control Board is launching the California Water Accounting, Tracking, and Reporting System (CalWATRS) on October 7, 2025. A link to the new system and additional information will be posted on the CalWATRS webpage on October 7th.
What You Need to Know
- You Can Create an Account on October 7th You’ll be able to create a CalWATRS account as soon as it opens, but you won’t be able to begin reporting until you receive a personal identification number (PIN) from the State Water Board.
- PINs Will Be Mailed in Mid-October The State Water Board will begin mailing PINs in mid-October. If you manage multiple water rights, you may receive multiple PINs.
- eWRIMS Usernames and Passwords Don’t Work for CalWATRS CalWATRS accounts require a new username and password. Your eWRIMS usernames and passwords will not work in CalWATRS.
- Large & Complex Water Rights If you manage a large or complex portfolio of water rights, please email
CalWATRS-help@waterboards.ca.gov before creating your CalWATRS account. We will work with you directly to ensure your account is set up correctly. - Public Outreach The State Water Board is planning a series of public events to help users navigate CalWATRS. It all kicks off with an Informational Item at the Board’s public meeting on October 7th. Upcoming events will be posted on the CalWATRS webpage as they are scheduled.
If you have questions or would like the CalWATRS team to attend an event in your area, please email CalWATRS-help@waterboards.ca.gov.
