California Water Accounting, Tracking, and Reporting System (CalWATRS)

As part of the CalWATRS rollout, we are bringing people in early to help shape the new system and make it better. Public feedback is key to building something that works for everyone, but since CalWATRS is a work in progress there will be some issues along the way. Early users will help us find and fix those issues, so we create a strong, reliable system. We appreciate your help and patience as we make this big improvement.

• CalWATRS Launches October 7, 2025
  Check back on October 7th for a link to the new system. Please Note: You'll be able to create a new account in CalWATRS as soon as it opens, but you won't be able to begin reporting until you receive your personal identification number (PIN) from the State Water Board. Continue reading to learn more about creating a CalWATRS account and when PINs will be mailed.
• Create a New Account
  To use CalWATRS, you'll need to create a new account with a new username and password. Please note: Usernames and passwords for eWRIMS will not work in CalWATRS.
• Migrate Your Water Right Records
  After creating a CalWATRS account, you'll complete a one-time record migration process to connect your existing water right records to your CalWATRS account. This process requires an individual 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 have more than one water right, you may receive multiple PINs (in a single letter or in multiple separate letters). To migrate all your water right records, you'll need all your PINs. CalWATRS will guide you through this process.
• Managing Multiple or Complex Water Rights
  If you manage a large number of water rights or have a complex portfolio, please contact us before setting up your CalWATRS account. We'll work with you directly to ensure your account is configured correctly and that all records are connected from the start. This helps prevent issues with record migration and ensures a smoother experience in the new system. Email us at CalWATRS-help@waterboards.ca.gov to schedule an appointment.
• 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. More information about creating organizations in CalWATRS will be added here soon.
• Public Outreach & Support
  The State Water Board will hold public workshops and informational meetings to help users get started with CalWATRS. Events details will be posted in the "Workshops & Meetings" section of this page as they are scheduled.

Stay informed and get hands-on help with CalWATRS. Below is a list of upcoming events where the CalWATRS team will present, demonstrate system features, and offer direct assistance to water right holders and agents.
